Special feature of 1905 film network The 52nd New York International Film Festival closed on October 12th, Beijing time. During the 16-day exhibition, although only a few films were world premieres, paul thomas anderson’s and david fincher’s high-expectation films undoubtedly set off a new wave of Oscar foresight. Documentary, edward snowden’s documentary that exposed the secret of American surveillance is also amazing. In the two days since the film was shown, it has caused heated discussion in all walks of life in the United States, and several major Hollywood film media have officially classified it as a potential player for the best documentary at this year’s Oscar.

Inherent vice commented on the double harvest of word-of-mouth box office of Gone Girl.

　 　 　At the Venice Film Festival in August this year, Barbara, the chairman of the festival, was obsessed with inherent vice and Gone Girl, which were "robbed" by the New York Film Festival. After the Toronto Film Festival ended earlier, many media were vague about this year’s Oscar situation, and many of them also considered that these two "highlights" had not been shown, which showed that these two films had high expectations in the industry. At the end of the New York Film Festival, "Gone Girl" ushered in a double harvest of word-of-mouth box office, while "inherent vice" was polarized because it was too surreal.

　 　 Inherent vice is paul thomas anderson’s latest stoner film noir, adapted from Thomas Pynchon’s novel of the same name in 2009. Because Pynchon’s novels have always been obscure and complicated, and they are typical absurd literary features, adapting them into films is a great test of the director’s skill. Therefore, it is not surprising that the film "inherent vice" won the polarized evaluation of film critics after its world premiere at the New York Film Festival. The reporter of Cinemablend, a well-known American film website, thinks that although the film is a typical stoner film, it tries its best to present strange and stupid interesting elements, but the plot is not attractive enough for people to see in the clouds and make the audience unknown so.[Click to view detailed film reviews]. However, "Variety" magazine believes that the film has cut down a lot of off-topic space and useless dialogue in the novel, while perfectly retaining the theme of the story, which is already very good. Photographer robert elswit’s skillful photography and magnificent color scenery also have extra points. Compared with Anderson’s previous works, the overall style of inherent vice is more biased, which is quite different from harmony.

　 　 In contrast, Gone Girl, directed by david fincher and starring Ben Affleck, is less controversial. Ten days after the official opening of the painting on October 3, it has won 78.3 million US dollars (about 480 million RMB) at the box office in the United States. As the opening film of the New York Film Festival, the film made its world premiere on September 26th, and immediately received rave reviews, and it was officially classified as a strong contender for this year’s Oscar.[Click to view detailed film reviews]However, in fact, this kind of love thriller film has not been shortlisted for the Oscar category, with the exception of 1987, which was shortlisted because of its great achievements at the box office. Now it seems that Gone Girl is likely to follow suit. According to foreign media reviews, Ben Affleck in Gone Girl continues his excellent acting skills, and several supporting actors, kim dickens, Carrie Coon and neil patrick harris, are also brilliant. The script adapted by the original author Gillian Flynn is impeccable. Deadline film critic Peter Hammond thinks that this film is to David Finch, just as it is to billy wilder and Hitchcock. If the later publicity is in place, there is no problem to be nominated for the best picture Oscar.

Snowden’s documentary "citizenfour" is a stunning addition to the Oscar battle.

　 　 This year, Steve James, Alan Hicks, and Gabe Polsky have already produced several powerful players in the Oscar documentary. However, the appearance of citizenfour by female directors Laura Poitras at the New York Film Festival still set off a strong public opinion upsurge, mainly because citizenfour is a film about edward snowden. The former CIA employee is world-famous for exposing the US Prism Gate project and exposing the US surveillance secrets. In addition to recording his life in Hongkong, Macau and Russia, the documentary also appeared in the former Guardian reporter Glenn greenwald, who helped him report the important secrets of the US National Security Agency. Their names are enough to attract the attention of citizenfour.

　 　 Citizenfour, which was shown at the New York Film Festival on the evening of October 11th, North America time, is the final part of the documentary trilogy directed by Laura Poitras. The first is "Iraq, My Motherland" in 2006, which recorded the life of the Iraqi people under American occupation and was nominated for the Oscar that year. The second documentary, in 2010, is related to bin Laden’s Al Qaeda and the military court at Guantanamo Bay. This time, "citizenfour" was directed by Petas by Snowden himself. Judging from the premiere reaction, it was considered to be the most exquisite of the three documentaries, and it was also the "most personal" documentary made by Petas.

　 　 Looking back on the history of Oscar for so many years, documentaries like citizenfour that question the American government are very suitable for the judges of the Academy. For example, The Panamanian Trick in 1991, The Waco Massacre in 1997, Fog of War in 2003, gasland in 2007, in 2010 and 2012, all of which were nominated for the best documentary. In addition, the popularity of this film by foreign media in the past few days after the premiere has greatly improved the chances of citizenfour’s impact on the Oscar.

The potential films are generally too serious. This year’s Oscar may be an "unexpected" dark horse.

　 　 The closing film of this New York Film Festival is from Alexsandro, which was shown at the Venice Film Festival before and will be released in North America this Friday. Birdman is not a good film in the normal sense, but it belongs to a more fun film, which is really rare in this year’s gloomy films.

　 　 Throughout this year’s Oscar-winning players, we will find that many of them should belong to the "melancholy" faction, such as the current powerful generals,, and, although they are admirable films, they are hard to bring people a good mood. Including several "good pictures" movies to be released soon. Tim burton’s, J·C· Chandor’s and Angelina Jolie’s are all excellent works, but none of them look pleasant. Even musicals, for example, are dark and melancholy.

　 　 Some critics believe that the news we saw in 2014 is probably Ebola virus, Gaza war, Syria and so on. It is no wonder that movies are so sad this year. But perhaps such a dense and serious theme will prompt the college to choose some "unexpected" films, such as Gone Girl mentioned above, and Nolan’s new film which will be released at the end of the year. After all, there have indeed been movies in the Oscar nominations for best picture, such as "Harmony" and "Harmony", which are more than 108,000 miles away from the taste of the academy.

　 　 Everyone likes to watch movies that please the audience, and the Oscar judges are no exception. There are no standards that stipulate what kind of films college voters need to nominate. In fact, the more diverse the film types, the better the whole competition process will look.

　 　 The nomination list for the 87th Oscar will be announced on January 15th, 2015, and the award ceremony will be held on February 22nd, 2015. Whether there will be a "dark horse" nomination that does not take the usual path this year, let us wait and see.

On June 16th, in Lidong Street, Hong Kong, the regional flags of National Flag of the People’s Republic of China and Hong Kong Special Administrative Region fluttered in the wind. Xinhua News Agency reporter Li Gangshe

　　Xinhua News Agency, Hong Kong, June 26 (Reporter Wei Hua) There are still a few days to go before the 25th anniversary of Hong Kong’s return to the motherland, and a festive atmosphere has permeated the streets of Hong Kong. On Hong Kong Island, Kowloon and the New Territories, large and small celebration banners and posters dot the streets. At night, bundles of colorful lights illuminate the dark sky of the city.

　　"Celebrate the 25th anniversary of Hong Kong’s return to the motherland", "Celebrate the return of Hong Kong with one heart and create the future with peers" and "forge ahead for 25 years and join hands to embark on a new journey" … … No matter on the external walls of high-rise buildings, or on the lampposts on both sides of roads, or on the body of tinkling cars driving leisurely, a series of celebration slogans come into view, and a red flag is particularly bright against the blue sky and white clouds.

　　As night falls, strolling along the Avenue of Stars by the sea, we can see the poster light show performed by the skyscrapers, which makes the Victoria Harbour, which is already brightly lit, more colorful. Bundles of lights shoot into the sky, dancing with the rhythm of music, and complement each other with the continuous light belt. The lights are projected onto the water, and the Victoria Harbour seems to be covered with a colorful coat.

　　Lidong Street is a pedestrian street located in Wan Chai, Hong Kong Island. The 200-meter-long street gathers many shops such as restaurants, teahouses and hand-run shops. With the approach of the anniversary of the reunification, red has become the main color of Lidong Street. The flag array composed of national flags and regional flags hangs high in the atrium, swaying gently with the wind, and the scene is spectacular, attracting passers-by to stop and watch.

　　Li Wenlong, the contact person of various associations in Wan Chai District, told reporters that the idea of building a "flag sea" in Lidong Street has long existed, and this plan has also been strongly supported by merchants. In addition, they will also light up special lighting to show Hong Kong’s multiculturalism near Wan Chai Waterfront Park and Victoria Park to welcome the anniversary of the reunification with the public.

　　A red sailboat "docked" at a lawn in front of the North Point Meeting. This sailboat is about 7.5 meters long, and the words "Celebrating the 25th anniversary of Hong Kong’s return to the motherland" are printed on three red sails.

　　Li Shaorong, secretary-general of the Hong Kong Eastern District Association, said: "The Hong Kong SAR has been established for 25 years, and this year is a new starting point. It is a blessing for us to build a sailboat and hope that Hong Kong will get better and better in the future. "

　　In yuen long merchants association secondary school, more than 250 teachers and students from 25 schools are creating large-scale murals. According to Lin Bizhu, vice chairman of the Yuen Long Literature and Art Association, the mural, which is more than 30 meters long, was created by teachers, students and volunteers at school and will be opened to the public on the 28th.

　　It is reported that this mural will depict the dream home in the author’s mind from many aspects, such as the feelings of home country, the characteristics of Hong Kong, the people’s Qi Xin’s anti-epidemic and people’s livelihood, so that the people can feel the feelings of the community and celebrate the 25th anniversary of Hong Kong’s return to the motherland.

　　Xinhua News Agency, Fuzhou, February 1st Title: Spring Festival travel rush, a station deep in the mountains, sticks to it.

　　Xinhua News Agency reporter Zhou Yi

　　Zhuyuan Station, located in Shanghang County, Longyan City, Fujian Province, is a fifth-class station on the Ganlong Railway. Here, the peaks are towering, the canyons are faint, there are no passenger trains stopping, no people are busy coming and going, only the small station people silently stick to it.

　　On the afternoon of January 29, the reporter bumped along the country path for an hour by car, and then climbed the mountain on foot before coming to the station deep in this mountain. The reporter saw that at the peak of Spring Festival travel rush’s return trip, the platform here was quiet. Liu Youwu, the stationmaster, said that Zhuyuan Station does not handle passenger business, but is only responsible for receiving and dispatching freight trains.

　　There are 6 employees in the station, 4 of whom are on duty every day. The youngest is 38 years old. The special nature of railway work determines that station attendant must stick to his post every minute, and everyone takes turns to work in shifts and "seamlessly connect" 24 hours a day. In the duty room of the small station, starting from the planned entry section of the train, report the time, open the signal, and jointly control with the driver … … Every time a train passes, station attendant has to answer the phone for nearly 10 times to confirm every link.

　　Liu Youwu told reporters that there is a one-way lane in the interval, and there are two lanes at Zhuyuan Station. If the trains go in opposite directions, they will meet here. By dispatching, one train is allowed to stop temporarily on one track, and then set off after another opposite train passes.

　　Liu Youwu, 60, has worked in the railway system for 36 years. When the reporter asked him how he felt about his work in Zhuyuan Station for many years, he said it was boring, but he insisted on it. "There is no signal on the mobile phone and TV on the mountain. I want to go to work more than resting. At least I can hear the driver’s call when I go to work." Liu Youwu said.

　　Deep in the mountains, it was already dark before 5 pm. In the night, there is a room and a lamp, and the employees on the job talk to the train driver who is about to arrive from time to time. "The personnel on duty can’t read books and newspapers, and safety must be guaranteed. Doing other things will be distracting." On the same day, station attendant Chen Jie said, "The hardest thing is the night shift. You can’t be a little confused. If you are sleepy, you will wash your face with cold water and turn around to refresh yourself. If you are sleepy, you will have to overcome it."

　　After the shift, Chen Jie touched the flashlight and went out, along the long rail, drifting away into the boundless night.

　　"The station staff should patrol a circle of lines before going to bed every day to see if there are any foreign bodies invading and if there are any small animals affecting the equipment. In winter, the wind is strong in the mountains. Standing on the bridge, we often joke that if we don’t eat fat, it will be blown away by the wind. " Luo Mouzhen, deputy stationmaster of Yuyuan Station, said.

　　Early the next morning, Liu Youwu came down from the mountain and went shopping as usual. "Although Zhuyuan Station is a railway station, the traffic is inconvenient. Every time everyone wants to go down the mountain, then take the bus to the town more than 10 kilometers away to buy food and prepare the ingredients for the week. " Liu Youwu said that in order to let employees eat fresh vegetables, he also reclaimed a vegetable field on the mountain and watered and weeded it in his spare time.

　　The station is located in the ravine, and the conditions are difficult. Every time the station staff go to work, they need to take the bullet train to Gutian Meeting Site Railway Station, which is 20 kilometers away from the station, and then take the township bus for half an hour to reach Zhuyuan Village, and it will take a long mountain road to reach the small station. Some employees have several scars on their hands and legs, which are caused by slipping and falling on the hillside in rainy days. "Some people once almost rolled into the valley, but fortunately, they caught the weeds on the side in time to save their lives." Luo Mouzhen said.

　　In addition, there is no running water in the station, and washing and cooking rely on a spring water flowing out of a stone crack on the top of the mountain. The staff of the station will go to the water source every two days to clean up the sundries and ensure the safety of drinking water.

　　When the reporter asked them how they persisted, the staff of the station said that although they did not transport passengers, it was particularly meaningful to think that coal, spring ploughing fertilizer and other materials in the mountains were dispatched through their intersection and then transported out of the mountains.

　　Near retirement, stationmaster Liu Youwu ushered in his last Spring Festival travel rush. For every plant and tree in the station, he has already had a constant feeling of giving up. This year, his biggest thought is still to stand on the last shift. "In Spring Festival travel rush this year, the number of freight trains has increased, and more than 30 trains have to be on duty day and night. The task of small stations is not easy, especially when the weather is cooling and the mountains are prone to freezing. Be more careful at this time."

　　During the period of Spring Festival travel rush, whenever he received the order to pick up the car, Liu Youwu would wait quietly on the platform with a flag in both hands. Trains galloping in the distance pass by here, bringing the persistence and love of the station people to the distance.

　　　　　　 CCTV News:The Ministry of Transport recently issued the "Guidelines for the Prevention and Control of COVID-19 Epidemic in Passenger Stations and Means of Transportation in Spring Festival travel rush in 2021", focusing on seven areas such as road passenger transport, urban public buses and trams, urban rail transit and waterway passenger transport, and formulating detailed epidemic prevention and control measures from five aspects such as disinfection, ventilation, transportation organization, personnel protection and publicity.

　　　　　　 In view of the characteristics of increased personnel flow and increased risk of epidemic spread during the period of Spring Festival travel rush, the Spring Festival travel rush Guide improved the prevention and control standards, made prevention and control by districts and levels, and comprehensively improved and strengthened prevention and control measures. During the period of Spring Festival travel rush, the disinfection frequency of passenger stations and means of transport should be appropriately increased. Strengthen the registration of passenger information, and fully implement the registration of real-name tickets for passengers on Class I and Class II passenger lines and inter-provincial and inter-city chartered passengers. Check the health code of passengers entering the road and waterway passenger station comprehensively, and provide services such as checking the health code on behalf of the elderly, children and other passengers who can’t use or don’t have smart phones, and assisting in filling in information. Temporary observation areas should be set up for 10 or more inter-provincial passenger vehicles and passenger ships, and the passenger load factors in high, medium and low-risk areas should not exceed 50%, 70% and 90% respectively. At the same time, strengthen the health monitoring and protection of employees, guide passengers to travel in the wrong peak, and take protective measures such as wearing masks, hand hygiene and "one-meter line" during various public transport.

　　CCTV News:Winter is the season of high incidence of respiratory diseases. Recently, in Yongchuan District, Chongqing, the number of outpatient and emergency departments in major pediatrics is at a high level, and various measures have been taken to effectively do a good job in the diagnosis and treatment of respiratory diseases in children.

　　In Yongchuan District People’s Hospital of Chongqing, recently, the daily average number of pediatric outpatient and emergency departments is about 800, of which more than 70% are children’s respiratory diseases. The hospital expanded wards, increased beds, and opened night clinics for children to facilitate children to seek medical treatment in time.

　　Wang Jun, Head of Medical Administration Department, Yongchuan District Health and Health Committee, Chongqing:Fever clinics in primary health care institutions should be fully opened, service hours should be extended, weekend clinics should be increased, 12 teams should be set up to help 23 primary health care institutions improve their ability to diagnose and treat respiratory diseases, and various measures should be taken to increase the supply of pediatric medical services, optimize the allocation of medical resources, and improve the ability of pediatric emergency services.

　　High incidence of respiratory diseases, multi-measures to deal with the peak of pediatric visits

　　At present, respiratory diseases have entered a period of high incidence. The number of people with cold, fever, cough and other symptoms has increased significantly in many parts of the country, especially many children infected with respiratory diseases, which not only worries parents, but also increases the number of diagnosis and treatment services in many pediatric hospitals.

　　Recently, the General Office of the National Health and Wellness Commission issued a notice to guide grassroots medical and health institutions to do a good job in health services for respiratory diseases in winter and spring, and put forward measures such as doing everything possible to tap resources to carry out pediatric diagnosis and treatment services and strengthening the support of general hospitals for grassroots medical and health institutions.

　　At 9: 40 in the morning, in the South Campus of Shuangqiao Hospital in Chaoyang District, Beijing, the number of children and parents waiting at the entrance of the pediatric clinic began to increase. Shuangqiao Hospital is a second-class general hospital in Beijing, with 27 clinical departments. The pediatric setting has continued since the establishment of the hospital. Now there are 4 pediatricians, which can meet the basic medical needs of children around the hospital.

　　According to the monitoring data of the hospital, in September, 2023, the average daily outpatient volume of pediatrics in the hospital was 74. After entering October, the data curve increased obviously.

　　Although the number of recent visits has tripled or quadrupled compared with daily visits, the reporter saw here that even during the peak hours of children’s visits, the number of people waiting at the entrance of the pediatric clinic never exceeded 12, and children and parents were basically divided into two clinics within half an hour.

　　In order to cope with the peak of respiratory diseases in autumn and winter in 2023 and reduce the stay time of patients in the hospital, Shuangqiao Hospital optimized the treatment process.

　　In the registration process, the outpatient hall dynamically adjusts the number of manual registration windows, every morning at 8: 00 — At 5: 00 pm, the pediatric registration is not limited. After the registration, you can wait outside the clinic.

　　Outside the clinic, the medical staff who are asking about the illness of the children are full-time medical assistants specially set up for pediatric outpatient clinics in the hospital.

　　Before the child sees a doctor, the doctor can get the basic information of the child from the doctor’s assistant. After a preliminary judgment, the parents of the child can take the test items prescribed by the doctor and take the child for further examination. In this link, the hospital has also carried out dynamic optimization.

　　In order to reduce the time for patients to wait for results, the number of hospital inspection personnel is also dynamically adjusted with the demand.

　　In addition to optimizing the medical treatment process, in order to cope with the epidemic peak of respiratory diseases, many primary hospitals have increased the number of consultation places and opened weekend clinics. At present, Shuangqiao Hospital has implemented holiday-free clinics in the south and north hospitals, and both hospitals are equipped with the same inspection and testing items.

　　Relieve the pressure of hospital treatment through community health service center

　　In order to cope with the long waiting time in pediatrics and the overload of some children’s specialized hospitals, the National Health and Wellness Commission has previously instructed all localities to publicize the information of medical institutions that can provide pediatric diagnosis and treatment services in the region, so as to facilitate patients to seek medical treatment nearby. Not long ago, Chaoyang District published a list of primary medical and health institutions providing pediatric services in its jurisdiction on the Healthy Chaoyang WeChat official account. Cuigezhuang Community Health Service Center is one of them. Recently, there have been more calls to consult pediatrics.

　　Sun Li hasn’t been idle since she took the office phone with her colleagues at 8 am. Most of the calls these days are for consultation with pediatrics.

　　At the same time as the other party consulted, Sun Li also made a preliminary understanding and judgment on the situation of the child.

　　In order to cope with the peak of respiratory diseases in the winter of 2023, Cuigezhuang Community Health Service Center began to optimize the consultation process as early as October and implemented pediatric holiday-free outpatient service. In order to make children infected in the community find out and treat them early, medical staff also make full use of the family doctor signing system to answer questions for the surrounding residents in the WeChat group.

　　Residents and doctors in the WeChat group are familiar with each other. Usually, when residents have a headache, they will directly ask for medicine in the group. For a long time, the two sides have established close ties. In such a special period, this close relationship will play a huge role.

　　In the winter of 2023, although a variety of respiratory diseases were prevalent, no new pathogens appeared. For doctors, these respiratory diseases are common diseases that have to be dealt with every autumn and winter. There is little difference in the diagnosis and treatment of mild children, whether they go to a specialized hospital or stay in the community.

　　Set up a hospital outpatient department in the community to facilitate children to see a doctor

　　In order to facilitate people to see a doctor in primary medical institutions, some general hospitals have also set up hospital outpatient departments in the community, and doctors have been stationed for a long time.

　　Recently, Ren Yumei, a pediatrician in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, was sitting in the Provence Community Hospital in Zhengzhou.

　　Ren Yumei, Deputy Chief Physician of Pediatrics, First Affiliated Hospital of Henan University of Traditional Chinese Medicine:Our community clinics have 1-mdash all the year round; Two specialists are stationed here. At the same time, according to the high incidence season of respiratory infection this year, the hospital sent 5-mdash; Six senior doctors, basically every day we have 2-mdash; Three specialists and general practitioners are together to jointly maintain primary diagnosis and treatment. At present, the community can realize the synchronous diagnosis and treatment process with the hospital, and can do basic blood routine, mycoplasma and influenza, including pulmonary ultrasound imaging, which can completely help us complete the preliminary diagnosis and treatment of common epidemics, infectious diseases and respiratory diseases.

　　Pluto, once "Laojiu", has now been "reduced" to a dwarf planet.

　　Our reporter Gao Bo

　　Not long ago, two foreign astronomers put forward a bold idea: the ninth planet in the solar system, which is "hidden from time to time", is likely to be an original black hole.

　　There is a black hole in the solar system that controls distant celestial bodies? Some experts said that this is an interesting hypothesis, but it is difficult to confirm or falsify with the current observation ability.

　　The vacant throne, there are new contenders.

　　More than a decade ago, who was the ninth planet was clearly written in the textbook. In 1930, clyde tombaugh discovered PLUTO, equating it with Uranus and Neptune, giving it the magnificent Greek name "Prouteau", and the nine planets in the solar system became a kind of common sense knowledge.

　　However, scientists later realized that Pluto seems to be "far from enough to see" in the outer space of the solar system. Since 1992, some distant ice-stone structures have been discovered one after another, and their volume is similar to Pluto. In 2005, it was discovered that the planet Eris was 27% more massive than Pluto! Pluto can be counted as the ninth largest, and it’s unreasonable that Venus doesn’t rank tenth.

　　Astronomers made a decisive decision, and the 26th International Astronomical Union held in August, 2006 passed a resolution: Pluto was classified as a dwarf planet and removed from the nine planets in the solar system. Prouteau abdicated tragically and became an asteroid 134340.

　　But the throne of the ninth planet is not so easy to cancel. In recent five years, some new discoveries have led people to speculate that there may be a real "P9" (the ninth largest planet) in the solar system.

　　On September 24th, another newcomer joined the battle for the throne — — ArXiv.org posted a paper, and Jakub Scholtz of Durham University in Britain and James Unwin of the University of Illinois in the United States put forward a bold idea: the ninth planet in the solar system may be an original black hole.

　　Strange orbit, pointing to the hidden "P9"

　　Around 2014, astronomers discovered some celestial bodies in the Kuiper Belt (the area near the ecliptic plane outside Neptune’s orbit). When the orbit is far from the sun, it can reach hundreds of astronomical units (one astronomical unit is the distance between the sun and the earth). At first, this was explained as the gravitational scattering effect of Neptune. But soon, the conjecture of the new ninth planet was put forward.

　　In 2016, michael brown of California Institute of Technology and his colleagues discovered that six celestial bodies in the Kuiper Belt have strange orbits, and their perihelions all point in the same direction. It’s like six clocks that turn at different speeds, but the hands all point in the same direction. If Neptune was behind the scenes, their directions would have been scattered and not so concentrated.

　　Moreover, when the six celestial bodies are closest to the sun, the distance is more than 40 astronomical units, and the Neptune hypothesis is not easy to explain.

　　Michael brown and his colleagues calculated that the probability of "big guys pointing to accidental coincidence" is 0.007%— — It is more realistic to believe that there is a "big guy who has not yet appeared".

　　Zhou Liyong, an astronomer and professor at Nanjing University, said in an interview with Science and Technology Daily that many people opposed the existence of "P9" at first. With the continuous discovery in recent years, the statistical significance of confirming the existence of the ninth largest planet has gradually increased.

　　Although "P9" has not been observed, some people have speculated its parameters through computer simulation: it is 200 to 800 astronomical units away from the sun, and its mass is 5-mdash that of the earth; Ten times, it takes 30,000 years to circle the sun … …

　　It is not necessarily the earth that wanders, but it may also be a black hole.

　　Astronomers used to believe that the possibility of a new planet outside Neptune is very small, because the material in this area is too thin, and it takes too long to grow a big planet. But what if the solar system "plundered" a ready-made planet from the vast universe? This possibility is worth considering.

　　"In fact, there may be many wandering planets in the universe, just like in the movie ‘ Wandering earth ’ Same. " Xie Jiwei, an astronomer who studies extrasolar planets and an associate professor at Nanjing University, told the Science and Technology Daily reporter that one way to find extrasolar planets is called gravitational microlensing method, which is to capture the weak deformation of images — — The light is distorted by the mass of a celestial body along the way to find clues about the existence of exoplanets. In this way, we have observed many "clues", indicating that there are many "tramps" who are unorganized and undisciplined in the unknown darkness.

　　In the suspected area of "P9", the gravitational anomaly was observed in the optical gravitational lens experiment (OGLE). At least six gravitational microlensing events indicate the gravity anomaly in this area, suggesting the existence of a free-floating celestial body with a mass range of 5-mdash; Between 15 earth masses. The conjecture of "P9" is therefore encouraged.

　　The new paper by Schultz and Unwin speculates that this celestial body may not be a rogue planets, but a wandering black hole. It was drawn into the group by the solar system, which disturbed the orbit of the outer celestial bodies.

　　Generally speaking, black holes observed by astronomers are gathered after the death and collapse of stars. The original black hole that exists in the theoretical assumption is another matter. Hawking made a great contribution to this concept: it was a "cultural relic" that came into being shortly after BIGBANG.

　　The universe before the Big Bang was called the primordial universe by astronomers. The explosion of the original universe was uneven, and the energy density in the local space was too high. Without collapsing, it was compressed into points with infinite mass and surrounding black holes. This kind of black hole varies in size, and it may be as small as a particle. The general primary black hole is similar in mass to the common asteroids in the solar system.

　　These black holes then drift around the universe. Some are dissipated by Hawking radiation and melted like ice; Others absorb substances and grow, and survive to this day.

　　Schultz and Unwin pointed out that the abnormal orbits of celestial bodies outside Neptune, as well as some gravitational events, can be explained by the original black hole whose mass is several times that of the earth; An original black hole may be captured by the solar system and become the ninth planet; They proved that the possibility of this capture is worth considering.

　　Strict assumptions, there are still many voices of opposition.

　　"The idea of this paper is still very rigorous and standardized, not a guess." Xie Jiwei said, "but the author also said that this is only a possibility. Introducing the concept of black hole may be interesting and strange to everyone. But the next step is still impossible. Moreover, whether there is the ninth largest planet is still a problem. "

　　Schultz and Unwin said that if "P9" is an original black hole, it may pass through the peripheral "halo" — — The positive and negative electrons in the outer layer of a black hole annihilate the light to determine its existence. However, a planetary scientist told the Science and Technology Daily reporter that such observation is difficult to achieve because the black hole is small and uncertain in its location.

　　"I personally don’t like the idea of the original black hole." An expert engaged in planetary research told the Science and Technology Daily reporter, "It feels almost mystical — — Can explain some phenomena, but basically never see it. "

　　"The discoverer of Kuiper objects, David Jewitt, didn’t even believe in ‘ The ninth planet ’ The existence of. " The expert said that David Jewett said in a TV interview that he didn’t think "P9" existed. He believes that the black hole hypothesis reveals that scientists are eager to make "major discoveries". But this theory is far from the stage of verification.

　　An important reason for different opinions is that it is still difficult to observe celestial bodies outside Neptune at the current level of human technology. Although humans have observed thousands of extrasolar planets.

　　"I don’t know the true face of Lushan Mountain, but I am only in this mountain." Xie Jiwei said, "Observing exoplanets basically infers the situation of planets indirectly by observing the Ling Xing effect or Doppler effect of star spectra. The planets in the solar system can be directly observed. The brightness of a planet is inversely proportional to its distance from the sun. Celestial bodies that are too far away will receive weak light and reflect weaker light. "

　　The periphery is so vast and the celestial bodies are so dim. Beyond hundreds of astronomical units, it is still unknown.

　　Xie Jiwei said: "Many celestial bodies on the edge of the solar system were seen through the Hubble telescope; After the Weber telescope works, our observation level will improve a little. "

I drive a Camry (parameter picture) twin engine, and there are three shortcomings that are unacceptable, and it is really expensive to change the battery. I advise people who want to buy a hybrid car to think twice, otherwise it will be too late to regret it!

The automobile industry is experiencing a great change that has never happened in a hundred years, and it has become an inevitable trend to develop new energy vehicles.

Plug-in hybrid vehicles and pure electric vehicles are the main models in the future, while hybrid electric vehicles will be eliminated in the future!

This is the real reason why Corolla twin-engine, Camry twin-engine, CR-V and other hybrid vehicles can’t be on the "green card"!

However, at present, Toyota and Honda-based hybrid electric vehicles have achieved high sales, and many consumers are waiting to see and want to buy a hybrid electric vehicle.

So is the current hybrid car worth buying? What are the shortcomings?

Next, I will analyze the advantages and disadvantages of the hybrid car and how much it costs to replace the battery, hoping to give some valuable information to readers who want to buy a hybrid car.

What’s the difference between Toyota THS, Honda i-MMD and BYD DM-i? Did DM-i learn from Honda i-MMD?

We want to know whether the hybrid car is worth buying. First, we need to understand the working principle of the hybrid car, so as to understand the advantages and disadvantages of the hybrid car!

At present, Toyota THS and Honda i-MMD hybrid systems are the main hybrid vehicles. Although both of them are hybrid systems, their working principles are obviously different.

The working principles of Honda i-MMD and BYD DM-i are more similar, so Honda CR-V has two hybrid models, one is a hybrid electric vehicle, and the other is a plug-in hybrid vehicle.

Honda’s i-MMD oil-electric hybrid uses clutches to realize three driving modes.

The first pure electric modeWhen the engine does not work, the clutch of the power separation device is disconnected, the vehicle is directly driven by the motor, and the power battery provides the power source. At this time, the working principle is the same as that of a pure electric vehicle.

The second hybrid modeThe vehicle is still directly driven by the driving motor, and the engine works normally. At this time, the power clutch is disconnected, and the engine is only responsible for driving the motor to generate electricity, and does not directly participate in the driving.

At this time, the working mode is more like an extended-range electric vehicle, and the driving principle is the same as that of an extended-range electric vehicle in Li ONE, so the engine always runs at the highest efficiency and the fuel economy is very high.

The third engine direct drive modeThe engine is working, the power clutch is closed, and the driver controls the power output of the engine through the throttle. At this time, the working mode is the same as that of the fuel vehicle.

When the vehicle needs to overtake and speed up, the motor intervenes to drive, and the auxiliary engine drives the vehicle together. At this time, the vehicle has the strongest power.

The above three driving modes are basically consistent with the working principle of BYD DM-i. Some people think that DM-I borrowed the working principle of i-MMD, but as early as 2008, BYD introduced F3DM, which is the world’s first mass-produced dual-mode vehicle.

The working principle of BYD F3DM is not the same as that of the familiar Tang DM, but the same as that of the Song Plus DM-I. As for why it was not accepted by the market at that time, the main reason was that the engine carried by the F3DM was too poor.

The DM engine is equipped with a 1.0L three-cylinder engine, and its power output is not strong. In the hybrid mode, the power output is insufficient, which makes it impossible to play the advantages of the hybrid mode, so it was eliminated by the market.

In 2012, Honda released the i-MMD hybrid technology, and in 2013, it officially launched the production model, so it was not DM-i that borrowed from i-MMD.

Toyota THS has developed into THS II, which is much better than the previous generation and can be divided into two driving modes.

The first pure electric modeThe engine does not participate in the work and will not start, and the vehicle is driven entirely by the motor, which is the first difference from Honda i-MMD.

However, the pure electric mode of Toyota THS II has a disadvantage, taking Camry twin engines as an example.

Because the battery is only 1.3kwh, it can only be turned on when the power is sufficient, and the pure electric mode can only travel about 2KM, and the speed cannot exceed 50km/h, otherwise it will directly exit the pure electric mode.

It can be said that the pure electric mode of Camry dual-engine is relatively small, but the application scenarios are still relatively rich. For example, the pure electric mode can be enabled when moving cars in short distances, congested roads and queuing, which can avoid the engine idling for a long time.

On the one hand, it can avoid carbon deposition caused by long idle speed of the engine, on the other hand, the engine stops working to achieve the purpose of saving fuel.

The second hybrid mode, due to the working principle of Toyota THS II, is divided into two working states in hybrid mode.

The first working stateDuring normal driving, when the Toyota THS II exits the pure electric mode, the vehicle directly enters the hybrid mode, and the engine and motor drive the vehicle at the same time.

When the power output by the engine is greater than the driving force required by the vehicle, the engine will drive the generator to charge the battery.

The second working stateWhen speeding up overtaking, long-distance climbing and high-speed driving, the engine and motor will still drive the vehicle together, but the engine will use all the power to drive the vehicle and the generator will stop charging the battery.

The power battery also uses all the electricity for motor-driven vehicles, at which time the vehicle has the strongest power. Because Toyota THS II has no engine direct drive mode, this is the second difference from Honda i-MMD.

The first disadvantage, the characteristics of the hybrid working mode of oil and electricity, can’t be green, can’t be exempted from purchase tax, and the price is expensive, saving fuel but not saving money.

Whether Toyota’s THS II or Honda’s i-MMD, the energy for driving vehicles in pure electric mode still comes from fuel.

The cruising range of pure electricity is too short, and the motor is only an auxiliary function. The main driving mode is the engine.

Therefore, hybrid electric vehicles are not new energy vehicles, so they can’t get a green license, and they can’t enjoy the same exemption from purchase tax as plug-in hybrid vehicles.

Take Camry twin engines as an example. The starting price is 219,800 yuan, 40,000 yuan more than the fuel version of the entry-level Camry, and 20,000 yuan more than the fuel version of the Camry with the same configuration.

Imagine that the hybrid of oil and electricity does save fuel, but can it save fuel and money?

I’ll work out an account for you.

With the same configuration, the fuel consumption of the fuel version Camry is 5.7L； per 100 kilometers; The average fuel consumption of Camry twin engines is 4.1L per 100 kilometers.

• The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.
• No.95 gasoline is 7.51 yuan per liter.

Camry dual engine saves 12.016 yuan in fuel per 100 kilometers compared with the fuel version of Camry. Driving 100 kilometers can save fuel in 12 yuan. Is it worth buying a hybrid car?

If the extra 20,000 yuan for purchasing the dual-engine version is used as fuel money,

20 thousand yuan can buy 95 # gasoline 150200L L.

The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.

Then Camry twin engines need to travel 93,875 kilometers to save the extra 20,000 yuan.

However, more than 90,000 kilometers, in addition to operating vehicles, basically few car owners can save fuel and money.

If a private car travels 10,000 kilometers a year, it will take at least 9 years to save money on fuel return, so it is said that hybrid electric vehicles save fuel but not money.

Moreover, it is not the same as plug-in hybrid cars. Although plug-in hybrid cars are also fuel-efficient and do not save money, they can get a green card without purchase tax, which is suitable for car owners.

Therefore, the first unacceptable disadvantage of the hybrid electric vehicle is that it saves fuel and does not save money. With the working principle similar to that of the plug-in hybrid vehicle, it can’t be a green card!

The second disadvantage is that the engine is noisy.

The engine noise of hybrid electric vehicle is very loud, which I felt on Camry twin engines, but it is not disturbing all the time, mainly in two cases, the engine noise will be very obvious.

In the first case, the cold car starts.

When the battery is fed, the cold car starts again. At this time, the engine noise of Camry dual-engine will be very loud, and the engine noise can be felt in the whole underground garage. Sometimes it will be caused by traffic jams for a long time, which may be because the engine water temperature is low.

When the car is cold, the engine can’t reach the best state, but it needs to drive the motor to charge the battery, which leads to the noise of the engine increasing under the combination of these two States.

In the second case, when driving at high speed, the battery is strongly charged.

When the Camry twin engines are driving on the highway, the engine cannot directly drive the vehicle due to the hybrid characteristics of Toyota THS II, so the battery must be charged.

Because the vehicle runs at high speed, it requires high power. At this time, it is necessary to drive both the vehicle and the motor to charge the battery, which leads to insufficient engine power.

In order to complete these two working conditions at the same time, the engine can only increase the speed, because the self-priming engine can only obtain the best power output at high speed.

Therefore, when driving at high speed and the battery is strongly charged, the noise of the engine will become very large. If it is sensitive to noise, it will affect the driving experience.

The third disadvantage is that the battery capacity is too small, and the power connection will shake.

As mentioned earlier, the battery capacity of the Camry twin-engine is only 1.3kwh, so it can only travel at a low speed of about 2km, which means that the Camry twin-engine basically travels in hybrid mode.

However, when switching from pure electricity to hybrid mode, sometimes there will be jitter, sometimes very small, sometimes very large, and sometimes not at all.

This is related to the small battery capacity. When the battery feed is switched to the hybrid mode, the engine needs to drive the vehicle and the engine to generate electricity at the same time, so the engine power is insufficient, and the power connection jitter appears.

If the power is switched when the battery is fully charged, and the engine and the battery drive the vehicle at the same time, there will be no jitter.

Therefore, the jitter caused by too small a battery may be unavoidable. This shortcoming is actually good, but it is somewhat unacceptable for car owners who pursue perfection.

Replacing the battery is expensive, so drive carefully.

Toyota and Honda’s hybrid electric system can be said to be very mature, and they all adopt "shallow charging and shallow discharging" to extend the battery life.

As long as the battery capacity of Toyota THS system is lower than 60%, it will stop discharging directly, while that of Honda is 55%.

This has both advantages and disadvantages. The advantage is that the battery can always be kept at more than 50%, which can increase the number of battery cycles and prolong the battery life.

The disadvantage is that the battery capacity of the hybrid electric vehicle is very small, and it is lightly charged and discharged every time, which makes it impossible to switch the power output mode for a long distance, which may cause the body to shake.

Due to the protection methods adopted by Toyota and Honda for the power battery, under normal use, the battery will basically not decay to the point where it cannot be used normally or be damaged.

Moreover, Toyota guarantees the battery for 8 years or 200,000 kilometers, and Honda guarantees the battery for 10 years or 200,000 kilometers, so the owner does not have to worry about battery damage, and it is expensive to replace the battery.

However, if the battery is damaged by the owner, it is not cheap to replace a battery.

Theoretically, taking the Camry dual engine as an example, the battery capacity is only 1.3kwh. At present, the power battery is 1,300 yuan /kwh, and it is 1,300 yuan to change a battery, plus the working hours are up to 3,000 yuan.

In fact, according to the maintenance cost of replacing the power battery exposed by the owner, it is obvious that it cost 23,848 yuan to replace the battery.

Therefore, it is not cheap to replace the battery in a hybrid electric vehicle, but as long as you drive normally, you basically don’t have to worry about the cost of replacing the battery.

Advantages of hybrid gasoline-electric vehicle

Although I mentioned the disadvantages of hybrid electric vehicles, its advantages cannot be ignored.

1. Whether driving at high speed or in traffic jam, the fuel consumption is relatively stable, and the fuel consumption per 100 kilometers is basically about 5L, which is very suitable for car owners who often run long distances.

2. A tank of oil can run more than 1000 kilometers, so you don’t have to worry about mileage anxiety, and you don’t have to refuel frequently. In today’s fast pace of life, the time saved is money.

3. No matter under any working conditions, the power of the hybrid electric vehicle can come at any time, the power output is better than that of the fuel vehicle, and the power ride comfort and driving experience are incomparable to that of the fuel vehicle.

The extra cost of buying a hybrid electric car may not be able to save fuel and money, but the driving experience is great!

Write it at the end

Hybrid cars are worth buying, but not for everyone.

If you don’t use cars frequently, don’t run at high speed, and just commute to work, then a fuel car is enough.

If there are requirements for power, endurance and long-distance driving, then a hybrid electric vehicle is worth buying.

If you buy a hybrid electric car just to save money, then I advise you to think twice. Actually, it doesn’t save money. If you buy it rashly, it’s too late to regret it!

China. com, December 16-Omicron mutant spreads quickly, is highly contagious and spreads invisibly. However, with the variation of the virus, the vast majority of infected people are mild or asymptomatic in clinical features. For people with mild and asymptomatic infections, people with no basic diseases or with stable basic diseases, they can take care of themselves at home. According to the "Guidelines for Home Treatment of Covid-19 Infected Persons" (hereinafter referred to as "Guidelines") issued by the State Council in response to the joint prevention and control mechanism of novel coronavirus epidemic, as well as the relevant tips from local CDC and medical experts, China. com combed the following 30 questions and answers, covering knowledge points such as protection, medication, medical treatment for key populations, vaccination, etc., to help the general public do a good job in personal protection and home treatment.

1. What should I pay attention to when I am infected with COVID-19?

The "Guide" clarifies that home therapists should take temperature measurement and self-health monitoring once every morning and evening. If symptoms such as fever and cough appear, they can take symptomatic treatment or oral medication. When necessary, you can also contact the medical staff of primary health care institutions or consult relevant medical institutions through Internet medical forms. Asymptomatic people don’t need medication. When taking medicine, home therapists should take it according to the drug instructions to avoid blind use of antibacterial drugs. If you have a basic disease, there is no need to change the dosage of the basic disease treatment drugs being used when the condition is stable. Antigen self-test and report the results according to the relevant epidemic prevention requirements.

If you have difficulty breathing or shortness of breath; After drug treatment, the body temperature remained higher than 38.5℃ for more than 3 days. The original underlying diseases are obviously aggravated and uncontrollable; Children have drowsiness, persistent refusal to eat, feeding difficulties, persistent diarrhea or vomiting; When pregnant women have symptoms such as headache, dizziness, palpitation, breath-holding, or abdominal pain, vaginal bleeding or bleeding, abnormal fetal movement, etc., they can be transferred to relevant hospitals for treatment by means of self-driving and 120 ambulances.

2. How to use medicine?

Reference Table of Commonly Used Drugs for Home Treatment of Infected Persons in Covid-19:

3. How to protect family members?

The Guide suggests that when you are at home, you should open doors and windows regularly every day to keep indoor air circulation. If you don’t have natural ventilation conditions, you can use exhaust fans for mechanical ventilation. Do a good job in ventilation and disinfection of shared areas such as toilets and bathrooms. Wash hands or disinfect hands when preparing food, defecating before and after meals, taking off masks, etc. Cover your nose and mouth with a tissue when coughing or sneezing, or cover your nose and mouth with the inside of your elbow, and throw the used tissue into the trash can. Do not share daily necessities with other family members. Tableware should be cleaned and disinfected after use. The surfaces of articles that may be contacted by home therapists and the towels, clothes and quilts they use should be cleaned and disinfected in time, and the personal belongings of infected persons should be placed separately.If the family shares the bathroom, the home treatment staff should disinfect it every time they use it; If family therapists use a separate bathroom, they can be disinfected once a day. Used paper towels, masks, disposable gloves and other household garbage are put into plastic bags and placed in special trash cans. Articles contaminated by saliva, sputum, etc. shall be disinfected at any time.

4. When can I end the home treatment?

The Guide makes it clear that if the symptoms of home-based therapists are obviously improved or have no obvious symptoms, the self-test antigen is negative, and the Ct value of Covid-19 nucleic acid detection for two consecutive times is ≥35 (the interval between the two tests is more than 24 hours), home-based therapy can be ended, and normal life and going out can be resumed.

5. What should I pay attention to when I go to the hospital?

Shen Ning, vice president of Peking University Third Hospital and director of the Center for Infectious Diseases: If you have fever and related respiratory symptoms and need to see a doctor, you should go to the fever clinic. When visiting a doctor, observe the relevant regulations of the hospital, especially self-protection, wear N95 mask regularly throughout the whole process, and comply with the relevant requirements of the hospital for nucleic acid and antigen. If you suspect that you have related upper respiratory symptoms and are worried about the risk of going to the hospital, you can choose online medical treatment, find experts in infectious diseases, respiratory medicine, Chinese medicine and related departments for consultation, and judge whether you need to go offline for medical treatment.

6. The emergency department and fever clinic can prescribe medicine for up to three days, but it hasn’t recovered after three days. Do you need to go to the hospital for reexamination?

Shen Ning: The self-limiting process of upper respiratory tract infection is about 5-7 days. Many patients’ symptoms are not completely relieved after 3 days. If the symptoms are relieved to a certain extent after 3 days of medication, there is no need to rush to return to the clinic. It is recommended to further observe the changes of symptoms. If the symptoms get worse, you must go to the hospital for a follow-up visit.

7. Can Chinese medicine and western medicine be taken together to treat Covid-19 infection? Can a variety of Chinese patent medicines be eaten together?

Liu Qingquan, President of Beijing Hospital of Traditional Chinese Medicine: At present, according to the research and clinical observation, Chinese patent medicines for treating COVID-19 and colds can be combined with western medicines such as antipyretic and analgesic drugs. Just to be on the safe side, Chinese medicine and western medicine should be separated by half an hour. If the ingredients of "Chinese patent medicine" used include drugs with western medicine for relieving fever and pain, attention should be paid to the combination of them, and side effects may occur after the drugs are superimposed. It is recommended not to combine several drugs, including traditional Chinese medicine and western medicine. As a result of combined use, there will be overlapping of drug doses, which has certain risks and will not improve the curative effect.

8. What traditional Chinese medicines can be selected?

Liu Qingquan: At present, all the Chinese patent medicines for treating colds and flu, especially those with wind-heat syndrome and external cold and internal heat (cold containing fire), have a very good effect on treating Omicron mutant.

9. How to protect pregnant women?

Qiao Jie, Dean of Peking University Third Hospital and Academician of China Academy of Engineering: If pregnant women’s family members are infected, they should be relatively isolated in space as far as possible if possible, and their living items should be separated as much as possible, and the bathroom should be disinfected, and the living space should be ventilated as much as possible. If a colleague is positive, try to work at home as much as possible. If you must work in the same space at the same time, pay special attention to the ventilation of the office space and wear N95 mask. Pregnant women should go to public places as little as possible, and do not get together or have dinner. Pay attention to hand hygiene while wearing a mask. Maintain balanced nutrition, adequate sleep and a positive and optimistic attitude. Pay attention to the standardized wearing of N95 mask when you go to the hospital for check-up, and reduce the waiting time. If you have any questions, you can consult in the form of online medical care.

10. What are the symptoms of pregnant women infected with Covid-19? Will it affect the fetus?

Qiao Jie: After the pregnant women were infected with Covid-19, the overall incidence, symptoms and course of disease were similar to those of the general population. The main symptoms were upper respiratory tract infection, such as cough, sore throat, sneezing, stuffy nose, runny nose, general aches and fever, and the severity was very few. The course of disease is basically 5-7 days, and the severe cases are mainly related to basic diseases, such as poor liver and kidney function, hypertension, diabetes, etc., which need to be treated in time. The mother has the protective barrier of placenta, so it is hardly transmitted to the fetus. However, if it is postpartum, it is best for Bao Ma to be isolated from the newborn or wear N95 mask to breastfeed.

11. How do pregnant women respond to symptoms?

Qiao Jie: When pregnant women have respiratory symptoms such as fever and dry cough, they can do nucleic acid test or antigen test to determine whether they are infected with Covid-19. Drink plenty of water, cool down physically, and choose traditional Chinese medicine available to pregnant women for symptomatic treatment. If western medicine is used to reduce fever, acetaminophen can be used for treatment if the temperature exceeds 38.5 degrees. When choosing antipyretic drugs, choose a single drug, and don’t stack it to reduce possible liver and kidney damage. Pay attention to monitoring heart rate, blood pressure and body temperature. Pregnant women in the third trimester should also pay attention to the monitoring of fetal movement, which can be monitored for one hour every day and have more than three fetal movements every hour. If the symptoms persist for more than 3 days, the fever does not improve after taking antipyretics, or fetal movement disappears, chest pain, chest tightness, abdominal pain, etc., you should contact the midwifery institution in time and see a doctor in time.

12. If COVID-19 is positive, can she give birth by herself?

Zhao Yangyu, director of the Department of Obstetrics and Gynecology, Peking University Third Hospital: Whether Covid-19 is infected or not, the choice of delivery mode is determined according to obstetric indications, and the doctor makes a comprehensive evaluation. For example, simple Covid-19 positive, no natural childbirth taboo (such as poor heart function, severe lung function, etc.), as long as you can tolerate the whole process of vaginal delivery, you can still choose natural childbirth.

13. What are the manifestations of children infected with COVID-19?

Qian Suyun, chief physician of Beijing Children’s Hospital: Most children mainly have fever, cough, runny nose and stuffy nose. Some of them are atypical symptoms, including fatigue, poor appetite, vomiting and even diarrhea. There are also some children who will have wheezing and hoarseness. However, the degree of children’s fever varies greatly from individual to individual, and some children can have a higher fever, even more than 39 degrees or 40 degrees. It is observed that most children have a fever in about 2-3 days. So the course of disease is about 3-5 days. The probability of serious illness is very low.

14. What medicines can families with children store?

Qian Suyun: Families with children should properly store some emergency drugs commonly used by children, but it is not recommended to store a lot of drugs. Improper storage may lead to children taking them by mistake. It is recommended to reserve drugs. The first category is antipyretic drugs. For children over 6 months, you can choose ibuprofen or acetaminophen, and one of them can be enough. Children between 2 months and 6 months are not suitable for ibuprofen, but acetaminophen can be used. For children within two months, it is not recommended to use antipyretic drugs routinely, and measures such as physical cooling can be taken and timely medical treatment can be taken. Cough is conducive to the discharge of respiratory secretions. Routine use of drugs is not recommended for children with mild cough. If there is nasal congestion and obvious cough, you can do atomization and wash your nose. At home, you can use a humidifier to increase the humidity in the air. If you have obvious cough, you can prepare some Chinese patent medicines for clearing heat and eliminating phlegm, and choose drugs suitable for your age, but don’t take two or more at the same time. Antipyretic drugs do not advocate taking the two drugs at the same time, and there is no need to take them alternately. Use drugs according to the age, dosage or doctor’s advice recommended in the instructions, and pay attention to the interval between two drugs. It is best for parents not to give drugs to their children according to their own experience or speculation. They can get medical advice and recommendations from professionals through the Internet.

15. Under what circumstances does the child need to be sent to a doctor?

Qian Suyun: The simplest way to distinguish is to look at the child’s mental state. If the child has fever and other symptoms, but he is in good spirits and can eat, drink and play after the fever has gone down, he can continue to observe and treat the symptoms at home. It is recommended to go to the hospital in the following situations: the fever lasts for more than 3 days and there is no sign of improvement; The child’s mental state is not good, including that the baby sometimes cries, is annoyed and is not easy to appease, and the older child is sleepy, listless and looks bad; In addition, cough is getting worse, which affects daily life and sleep; Some children wheeze, breathe faster, even have difficulty breathing, and have obvious hoarseness. Be careful of laryngitis and laryngotracheitis; If you have consciousness disorder or convulsion, you should see a doctor immediately. Children under three months are a special group, including newborns and infants. Once they have fever, it is recommended to see a doctor in time.

16. How should the elderly protect themselves?

Li Yanming, Director of Department of Respiratory and Critical Care Medicine, Peking Hospital: First of all, we should vaccinate, including whole-course vaccine and booster vaccine, which can obviously reduce the incidence of severe illness. Second, reduce going out, especially avoid going to closed places where people gather. If you really need to go out, wear a mask. Try to minimize contact with the external environment during the whole process, and wash your hands when you come back. Third, pay attention to keep warm while strengthening ventilation. You can put your elderly friends in another room and let them return to the room after the ventilation is over and the room temperature returns to normal. Fourth, to control basic diseases, we can buy medicines through various channels, or let relatives and friends buy medicines. Fifth, ensure regular sleep and nutrition, but don’t overeat. Reduce alcohol and tobacco as much as possible. Family members who don’t live with the elderly can reduce their visits and reduce the chances of virus exposure in the near future. If the co-residents are infected with Covid-19, they can live alone if conditions permit. If conditions do not allow, it is necessary to have an independent room, close the door and strengthen ventilation. Patients should be cleaned and disinfected after touching toilets, door handles and faucets.

17. What are the precautions for drug use in the elderly?

Li Yanming: After the elderly are infected with Covid-19, we should first strengthen observation and monitoring. Second, we should strengthen daily care, including light diet. After infection, the gastrointestinal function of the elderly is not good. It is recommended to eat less and eat more meals to avoid vomiting after eating a lot of food at one time. Ensure sleep; Replenish a proper amount of water, combined with body temperature and sweating, a small amount for many times, to prevent gastrointestinal discomfort and increase heart load caused by a large amount of water supplement at one time. Third, the higher the body temperature and the older you are, the more careful you should use drugs to prevent the elderly from sweating a lot after using a fever to cause collapse or even hypotension; In addition, the fever should be slowed down, and the fever can be reduced by physical means; Avoid using multiple drugs together when using antipyretics and cold medicines. Fourth, the application of proprietary Chinese medicines should be less and more precise, and multiple proprietary Chinese medicines with the same function should not be used at the same time. Fifth, the elderly with basic diseases should strengthen the management of basic diseases. A large amount of water loss caused by fever may lead to a decrease in blood pressure. During the fever, especially when antipyretics are used, pay attention to blood pressure monitoring. If the blood pressure is lower than the normal level, the antihypertensive drugs should be reduced or even stopped, and then used as usual when the blood pressure returns to normal. The elderly may eat little after infection, so it is necessary to monitor the changes of blood sugar to prevent hypoglycemia. When the elderly have fever and weakness, they must prevent falling.

18. Under what circumstances do you need to send the elderly to the hospital?

Li Yanming: We should strengthen the observation of the elderly and understand their basic situation. Such as basal heart rate, basal blood pressure, respiratory rate per minute and body temperature. For the elderly with cardiopulmonary diseases, it is necessary to know their basic peripheral oxygen saturation. Observe the changes of the general situation of the elderly, such as conscious state, mental state, defecation and eating. If the following situations occur, you need to consider seeking medical treatment: First, symptoms such as fever persist or tend to worsen. Second, there are new symptoms, such as chest pain, dyspnea, incontinence or sudden immobility of limbs, especially unilateral immobility of limbs, or inability of the elderly to eat, nausea and vomiting, or drowsiness, unconsciousness and disorientation. In addition, the aggravation of basic diseases, such as coronary heart disease in the elderly themselves, leads to angina pectoris; It turned out that there was chronic obstructive pulmonary disease or asthma, and there was an aggravation of chronic obstructive pulmonary disease and asthma, and they all needed to see a doctor.

19. What should cardiovascular patients pay attention to?

Zhou Yujie, Executive Vice President of Beijing anzhen hospital: Patients with original cardiovascular diseases are taking basic drugs. Drinking more water after high fever may affect the symptoms of heart failure, such as drugs for relieving muscle soreness and cardiovascular drugs. At present, no adverse effects between them have been found, so there is no need to be anxious. Manage the basic diseases of the heart well, use the original drugs for cardiovascular diseases well, increase the body’s immunity, improve their sleep quality and overcome anxiety. Don’t stop taking drugs for cardiovascular disease prevention and control for a long time. If you have persistent chest pain, seek medical advice promptly. Pay attention to keep warm, control the intake of sugar, oil and salt, and keep moderate exercise, not too intense. Monitor blood pressure, heart rate and blood lipid regularly.

20. How to sterilize at home?

Lu Lian, Director of the Hospital Sense Management Office of beijing ditan hospital, said: The risk of being infected by household items after "Yangguo" home rehabilitation is very small. The family can do daily cleaning without terminal disinfection. You can unplug the refrigerator and wipe it with a wet towel containing alcohol. Food that is not sealed in the refrigerator is heated before eating. Wipe hard surfaces such as toilets, desktops and cabinets with alcohol wipes or chlorine-containing disinfectant. Cotton items can be washed normally in the washing machine, and the quilt can be dried in the sun. Physical disinfection methods such as sun exposure and heat are preferred at home. To do a good job of ventilation, it is recommended to ventilate 2-3 times a day for at least 30 minutes each time. Household disinfection should focus on cleaning, supplemented by chemical disinfection.

21. What should I pay attention to when disinfecting?

Peking Union Medical College Hospital: Spraying 75% alcohol in a confined space for air disinfection may easily lead to fire or even explosion. Use chlorine-containing disinfectant to disinfect the surface of metal countertops or leather products that are easy to corrode. Disinfectants cannot be used to directly disinfect the human body. Stimulating the airway after inhalation will lead to cough and even destroy epithelial cells. It needs to be wiped after spraying with disinfectant, and pure chemical action can’t completely disinfect it. After disinfection with chlorine-containing disinfectant, the list of objects should be cleaned. The concentration of disinfectant used should not be too high or too low. Different types of disinfectants should not be mixed. Disinfectant can’t be added to the laundry detergent, and a large amount of water is diluted during washing, which can’t play a disinfection role; Chlorine disinfection will corrode and destroy the inner container of washing machine.

22. How long can I return to work after the fever has gone down?

Li Dongzeng, Chief Physician, Department of Infectious Diseases, Beijing You ‘an Hospital: Under normal circumstances, the symptoms of cough, nasal congestion, runny nose and sore throat will be obviously relieved in 3 days after the body temperature is normal. When somatosensory sore throat and cough no longer affect sleep, it means that the body has basically recovered and is suitable for returning to work. After 7 days of onset in young adults, the nucleic acid gradually turned negative, and the infectivity was low. COVID-19 should still do a good job of respiratory protection after recovery, and do not lower the prevention and control standards. After returning to work, stick to wearing masks in crowded and closed public places, pay attention to hand hygiene, cough, sneezing and other etiquette. Don’t eat face to face in the canteen.

23. Is there a high chance of reinfection after rehabilitation?

Zhong Nanshan, academician of China Academy of Engineering: After being infected with Omicron once, antibodies will be produced in the body, which is equivalent to being vaccinated once. At present, the data show that after being infected with Omicron once, the rate of reinfection within one year is very small.

Wan Mobin, Chief Physician, Department of Infectious Diseases, Shanghai Changhai Hospital:There are three types of people who are more susceptible to repeated infections, including the elderly, people with basic diseases and people with poor immunity.Self-protection awareness should be strengthened after the cured confirmed patients in COVID-19 are discharged from hospital and asymptomatic infected people are released from isolation. Vaccination, wearing a mask, keeping a social distance of 1 meter, and trying to avoid being in crowded and poorly ventilated indoor spaces are still effective ways to prevent repeated infections. In addition, in daily life, we should also increase nutrition, especially increase the intake of protein, keep exercising, ensure a good attitude and improve the body’s immunity.The risk of reinfection, as well as the symptoms after infection, depends on many complicated factors, including the variation of variants, vaccination and previous physical conditions. It is true that a small number of infected people are at higher risk after reinfection, but for most people, there is no need to worry too much about the aggravation of symptoms after reinfection.

24. What are the taboos for vaccination?

Beijing Center for Disease Control and Prevention: The medical staff at the inoculation point are responsible for the taboo judgment, and the clinicians at the secondary and above medical institutions are responsible for the disease diagnosis. The diagnosis certificate issued should specify the recent detailed state of the patient, so as to facilitate the taboo judgment at the inoculation point. Taboos include: ① severe allergic reactions, such as anaphylactic shock and laryngeal edema, occurred during previous vaccination; ② Acute infectious diseases are in the fever stage and vaccination is suspended; ③ Vaccination is suspended for serious chronic diseases during acute attack, such as cancer patients undergoing chemotherapy, patients with hypertensive crisis, patients with coronary heart disease who have myocardial infarction, autoimmune nervous system diseases in the advanced stage, and epilepsy patients in the attack stage; ④ Life has entered the terminal stage due to serious chronic diseases.

25. Does it mean that the COVID-19 vaccine has not been vaccinated because of the basic disease and other reasons?

Wang Huaqing, chief expert of immunization program of China CDC: There was a serious allergic reaction after vaccination, so we can’t vaccinate this vaccine in the future. Most other situations belong to the situation of slow seeding. In the early stage, because of the basic diseases, the vaccine could not be vaccinated in the evaluation process, and most of them belonged to slow seeding. They have entered the stable period of the disease or the special treatment condition is over. After re-evaluating the conditions, it is still recommended to vaccinate as soon as possible.

26. Is the adverse reaction rate of COVID-19 vaccine for the elderly high?

Wang Huaqing: According to the current monitoring situation, the overall reported incidence of adverse reactions among the elderly aged 60 and above after being vaccinated with Covid-19 vaccine is slightly lower than that of people under 60, and the incidence of serious adverse reactions is basically similar to that of other people, which is less than one in a million.

27. How long is the interval between strengthening immunization?

Beijing Center for Disease Control and Prevention: Vaccination with COVID-19 vaccine can effectively reduce the risk of severe illness and death after infection. The elderly who have no vaccination contraindications and meet the vaccination conditions should be vaccinated as soon as possible, and the booster immunization should be completed as soon as possible after 3 months of complete vaccination.

28. Who is the target group of the second dose of booster immunization?

According to the "Implementation Plan for the Second Dose of Enhanced Immunization of Covid-19 Vaccine" (hereinafter referred to as "Implementation Plan") issued by the Comprehensive Group of Joint Prevention and Control Mechanism for novel coronavirus Epidemic in the State Council, at this stage, on the basis of the first dose of enhanced immunization, the second dose of enhanced immunization can be carried out among people with high risk of infection, people over 60 years old, people with serious basic diseases and people with low immunity.

29. How long is the interval between the second dose of booster immunization?

According to the real world research and clinical trial data at home and abroad, combined with the actual vaccination in China, the time interval between the second dose of booster immunization and the first dose of booster immunization is more than 6 months.

30. What vaccines can be selected for the second dose of booster immunization?

According to the progress of vaccine research and development, all vaccines approved for conditional marketing or emergency use can be used for the second dose of booster immunization. Priority is given to sequential booster immunization, or the second dose of booster immunization with vaccines containing Omicron strain or with good cross-immunity to Omicron strain. The relevant combinations are as follows:

3 doses of inactivated vaccine +1 dose of Kangxinuo intramuscular recombinant Covid-19 vaccine (adenovirus type 5 vector); 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (CHO cells) of Chifeilongkema; 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (adenovirus type 5 vector) for Kangxinuo inhalation; 3 doses of inactivated vaccine +1 dose of Zhuhai Livzon recombinant Covid-19 fusion protein (CHO cell) vaccine; 2 doses of Kangxinuo intramuscular adenovirus vector vaccine +1 dose of Kangxinuo inhalation recombinant Covid-19 vaccine (adenovirus vector type 5); 3 doses of inactivated vaccine +1 dose of Chengdu WEEK recombinant Covid-19 vaccine (sf9 cells); 3 doses of inactivated vaccine +1 dose of Beijing Wan Tai nasal spray influenza virus carrier Covid-19 vaccine; 3 doses of inactivated vaccine +1 dose of Zhejiang clover recombinant Covid-19 protein subunit vaccine (CHO cells); 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 bivalent S trimer protein vaccine from Shenzhou cells.
