　　Give you a heads-up

　　Every summer, all kinds of seemingly eloquent "popular science" are "listed" simultaneously with big and red cherries.

　　Recently, a video about the quality and safety of cherries spread on the Internet, saying that "99% of cherries on the market use swelling agents. Normal cherries can only grow to 12-mdash; The weight of 13 grams can be doubled with swelling agent. If there is no kernel in the cherry pit, the hollow one is medicated … …”

　　What is the swelling agent that is often named? Is there really a miraculous effect in the rumor? What factors are related to the size of the cherry? To this end, the reporter visited experts in the agricultural field and consulted people on issues of concern.

　　No food safety incidents caused by it have been found yet.

　　"The swelling agent is a plant growth regulator. In the process of cherry growth, in order to improve pollination rate and fruit setting rate, cherry planted in greenhouse usually needs to use swelling agent; Cherry cultivated in the open field does not need to be used. " Wang Qiang, a researcher at the Agricultural Products Quality and Safety Risk Assessment Laboratory (Hangzhou) of the Ministry of Agriculture and Rural Affairs, told the reporter that at present, open-field cherry is the mainstream cultivation mode in China. According to this calculation, it is indeed possible to use plant growth regulators such as bulking agents in cherry market, but the utilization rate should be less than 50%.

　　How do plant growth regulators play a role in the production of fruit and vegetable products?

　　"Plant growth regulators have similar effects to plant hormones, which can stimulate the division and growth of plant cells. The difference is that plant growth regulators are artificially synthesized by scientists and modified to make their activities stronger than plant hormones." Xu Dong Hui, a researcher at the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences, said.

　　In terms of management, since 1997, according to the Regulations on Pesticide Management, plant growth regulators have been managed as pesticides.

　　According to the relevant person in charge of the Ministry of Agriculture and Rural Affairs, at present, there are nearly 40 registered plant growth regulators in China. There are more than 100 kinds registered and used internationally. Approved and registered plant growth regulators should formulate technical specifications for safe use, including medication period, dosage, application method, scope of use, matters needing attention and safety interval, and clearly mark them on product labels to guide farmers to use them reasonably. In addition, a series of residue tests should be carried out for registered products, and residue limit standards and reasonable use criteria should be formulated according to data such as residue tests to ensure the quality and safety of agricultural products. Since 2015, the Ministry of Agriculture and Rural Affairs has conducted a risk assessment of plant growth regulator residues in agricultural products, and the results show that the average residue value of plant growth regulators is only 0.001— 0.034 mg/kg, the risk of dietary exposure is very low, and the product quality and safety are guaranteed.

　　Experts said that in terms of safety, there have been no food safety incidents caused by plant growth regulator residues in the world so far. In China, agricultural products that have been applied with plant growth regulators are also very safe for consumers. Compared with other pesticides, although plant growth regulators are included in the management of pesticides, they are not pesticides for treating diseases, insects and weeding in the traditional sense. Their products are of low toxicity, and some of them are even listed as exempted substances without setting residue limits because they are almost nontoxic. For example, the toxicity of chlorfenuron commonly used in expanded fruits (LD50 > 4,918 mg/kg) is lower than that of salt (LD50 = 3,200 mg/kg). In addition, because the amount of plant growth regulator is small, excessive use is easy to produce adverse effects, and farmers can not use it in large quantities, so the residue of plant growth regulator is low.

　　Fruit size is determined by many factors.

　　Then, what factors are related to the size of cherry fruit, and can the swelling agent "double" the fruit?

　　According to experts, large cherry and seedless cherry are related to variety characteristics, cultivation measures and the use of plant growth regulators.

　　Xu Donghui told reporters that "Meizao" is the largest fruit among the cherry varieties at present. This variety of cherries has the characteristics of large fruit shape, full and sweet taste. Under normal circumstances, the single fruit weight of "Meizao" is 8-mdash; 12 grams, which can reach 16-mdash under special cultivation methods; Twenty grams.

　　"A sweet cherry variety selected in China ‘ Red light ’ Under normal circumstances, the weight of a single fruit can reach 11-mdash; Fifteen grams. From the point of view of drug control, it has been reported in literature that treating cherry with plant growth regulator gibberellic acid can increase the weight of single fruit by about 15%— 30%, the swelling effect is limited. " Wang Qiang said.

　　So, does cherry seedless mean that it has been treated with swelling agent? Wang Qiang said, this statement is too absolute. Although it is reported in the literature that cherry stones will be hollow after being treated with gibberellic acid at a certain concentration, it is not necessarily 100% seedless after being treated with gibberellic acid at a low concentration. In addition, the causes of cherry hollowness are natural abortion or other possibilities, not necessarily because of the use of gibberellic acid and other drugs.

　　Xu Donghui explained that in order to improve the pollination rate and fruit setting rate of cherries, fruit farmers will apply gibberellin and other plant growth regulators at flowering stage, which may also cause seedless fruits and nuts, but this will not affect the safety of cherries.

　　As an important supporting regulation for deepening the reform of the taxi industry, yesterday, the Ministry of Transport announced the newly revised Regulations on the Management of Taxi Drivers’ Qualification and the Regulations on the Management of Cruise Taxi Services. The two regulations are clear. Both the traditional cruise taxi driver and the online booking taxi driver must pass the national public and regional subject examinations to obtain the qualification certificate and be registered by the taxi administrative department before they can engage in taxi passenger service. The two regulations will be implemented on October 1 and November 1 this year respectively.

　　■ ask questions

　　● Why do you want to manage the drivers of the network car?

　　According to the Ministry of Transport, whether it is a network car or a cruise car, it provides a universal passenger service for the public and implements access management for drivers according to law, which is the bottom line requirement for industry management departments to ensure transportation safety and service quality.

　　● In what aspects have the characteristics of the network car been considered?

　　In the revision of "Regulations on the Management of Taxi Drivers’ Qualification", the characteristics of the network car are fully considered, and the development of new formats is actively supported through "tailor-made" system design and management innovation. For example, compared with the tour bus driver, it simplifies the test content of the network car driver to the greatest extent, and stipulates that its registration and cancellation can be completed through the platform company reporting to the taxi administrative department where the license issuing organ is located.

　　Regulations on the management of cruise taxis

　　"Money" should be adjusted in time.

　　According to the framework of rules and regulations issued by Guiding Opinions on Deepening Reform and Promoting the Healthy Development of Taxi Industry and Interim Measures for the Management of Online Booking Taxi Management Service, the revised Regulations on the Management of Cruise Taxi Management Service has adjusted the scope of application and made a series of regulations on the positioning of taxi industry and the distribution of interests between operators and drivers. It is clear that taxis are an integral part of urban comprehensive transportation system, a supplement to urban public transportation, and provide personalized transportation services for the public. The development of cruise taxis should be adapted to the economic and social development of the city and coordinated with public transportation and other passenger transport services. By defining the development orientation, we will strive to build a diversified and differentiated urban comprehensive transportation service system to better meet the travel needs of the people.

　　Aiming at the problem of taxi "money", cruise taxi operators are required to adjust the contract fee standard or quota task in time according to operating costs, freight rate changes and other factors, so as to better build a business model in which enterprises and drivers share operational risks and distribute benefits reasonably, and accelerate the transformation and upgrading of traditional industries.

　　■ background

　　Two provisions provide the guarantee of the rule of law.

　　In July this year, the Ministry of Transport issued "Guiding Opinions on Deepening Reform and Promoting the Healthy Development of Taxi Industry" and "Interim Measures for the Management of Online Booking Taxi Operating Services" as important supporting regulations for deepening the reform of the taxi industry. Yesterday, the Ministry of Transport issued newly revised Regulations on the Management of Taxi Drivers’ Qualification and Regulations on the Management of Cruise Taxi Operating Services and made relevant interpretations.

　　The Ministry of Transport said that the amendments to these two ministerial orders sought the opinions of local transportation authorities in early July this year, which will provide legal protection for promoting the transformation and upgrading of cruise vehicles, standardizing the operation of online car-sharing, and promoting the integration and development of new and old formats.

Two sets of contradictory data: year-on-year decline and year-on-year increase of lottery tickets …

Just now, the Ministry of Finance announced that the national lottery sales in December last year was 53.284 billion yuan, a year-on-year decrease of 8.565 billion yuan and a year-on-year decrease of nearly 14%.

According to the data, the total lottery sales amount increased last year, and the growth rate was as high as 36.5%.

-Why did the lottery ticket, whose sales trend rose as a whole, suddenly get cold in December?

We may find clues from a lottery incident in Jiangxi.

Let’s review the 220 million yuan lottery event in Jiangxi.

On December 2, 2023, a lottery player in Jiangxi spent 100,000 yuan to buy 220 million yuan in the lottery, becoming an unprecedented lucky dog.

This lottery event soon became a hot spot. Then, it is a constant voice of doubt, followed by! !

There are many doubts about the winning event, and public opinion has focused on at least three points:

First, who will suddenly spend 100,000 yuan to buy lottery tickets? This doesn’t make sense in the logic of normal people’s thinking. Even the old lottery players would not be so bold.

Second, how did the winners "accurately bet" the same group of numbers, and they got 220 million yuan in luck. Look carefully, that is, betting on the same group of numbers, without avoiding the risk of betting at all, that is, putting eggs in the same basket.

Third, the grand prize triggered risk control, and you can receive all the bonuses of more than 220 million yuan without paying taxes. This is not an insider, and it is estimated that no one really knows this rule.

There are many ways to eliminate the tire pressure lamp of Golf 7.

First of all, you can operate through the navigation system: open the navigation, click the menu, find the original car settings, there will be tire pressure options, click to enter and follow the prompts to eliminate the operation. Secondly, if you change the music system, you can find the original car information button inside, find the tire button after entering, then enter to see the TPMS settings, click reset and press OK. In addition, you can also operate through the buttons on the steering wheel: first press an upward arrow on the left side of the steering wheel, then press the R key on the table, and then press the plus sign on the right side of the steering wheel to restart the vehicle to eliminate the tire pressure light. Finally, you can also find the multi-function steering wheel for reset operation. These methods can effectively eliminate the tire pressure lamp of golf 7.

　　On February 14th, the 29th day of the twelfth lunar month, Hanlingou, Qunli Village, Lianhe Town, Zhongjiang County, was particularly lively. More than 260 villagers had a dam feast together on the newly-built social road. The whole village was full of 24 dining tables, and Tan Lichun, a villager of this village, invited them to have a group dinner.

　　Tan Lichun is the chairman of Jiangsu Xinhongtai Electromechanical Co., Ltd., and his tenacious will and hard-working spirit have been honed from a poor life. After graduating from technical secondary school, he was assigned to an enterprise to repair aircraft engines. After two years of work, he resigned and went to work in Guangdong. However, the road to success was not smooth. After half a year, I returned to Deyang to work because I felt that there was no future. With his own skills and hard-working spirit, Tan Lichun won the position of an engineer in a home appliance enterprise and began to contact mechanical and electrical enterprises all over the country. After accumulating various experiences, he resigned again and went to Jiangsu to start a business.

　　"In 2006, I established the first Hongtai electromechanical company. The road to entrepreneurship is full of hardships, but it is also very lucky. After 12 years of hard work, the enterprise is now on the right track … "Tan Lichun tells the story of starting a business.

　　After starting a successful business, he always cares about the development of his hometown and the life of the villagers, and returns to his hometown every year. When he sees that the village road that he often passes through when he was young has not been fundamentally changed, his heart is extremely restless. In 2017, when he learned that Murakami planned to build roads, but there was still a funding gap, he generously donated 100,000 yuan. "In the second half of 2017, due to the rising price of road building materials and insufficient planned funds, he decided to pay for the gap. Now that the road has been repaired, Boss Tan plans to invest 100,000 yuan to install 50 solar street lamps … "Li Fuxiao interjected.

　　When Tan Lichun went home for the Spring Festival this time, he learned that there was still a funding gap in the construction of village roads, so he decided to pay for it again, and at the same time he was going to pay for the installation of solar street lamps. In order to repay the villagers, on the 29th of New Year’s Day, he invited a chef and put on a dam feast to celebrate the New Year with the villagers.

　　"In the past, we only had dirt roads from Hanlingou to the town and neighboring villages. Since the village roads hardened, it has facilitated life and production, and agricultural and sideline products can also be shipped out." Villager Zhang Hai said happily. "Now, the car can drive to the door, and I am no longer afraid of muddy roads in rainy days. Thanks to Tan Lichun, who is a native of our village, it is really hard to get’ rich and never forget my hometown’." Villager Tan Wen praised Tan Lichun’s actions.

　　"The mountains and rivers in my hometown and my fellow villagers raised me, and I am very proud to be able to do something for the people in my hometown today!" Tan Lichun admits that the idea of doing something for his hometown has a long history. This is just a token of gratitude to his hometown. Facing the praise of the villagers, he feels that he can do something for his hometown. "I have suffered from it since I was a child. At that time, the neighbors often helped me. Now that I am rich, I should care more about the development of my hometown. It is also appropriate to do something for the villagers."

　　Shanghai News, June 1st (Reporter Chen Jing) May 30th every year is World Multiple Sclerosis Day, which was established by the International Multiple Sclerosis Union (MSIF) in 2009 to arouse the world’s attention to the disease. This year’s theme is "making love accessible, connecting you and me", aiming at strengthening the connection between patients with multiple sclerosis and between patients and society, and helping them gain more understanding and care.

　　In order to help more people understand Multiple sclerosis, enhance the public’s attention and reduce the burden of patients’ disease management, Professor Yan Xu, chief physician of neurology department of Peking Union Medical College Hospital, Professor Chen Xiangjun, chief physician of neurology department of Huashan Hospital affiliated to Fudan University, and Professor Qiu Wei, chief physician of neurology department of the Third Affiliated Hospital of Sun Yat-sen University, gave scientific answers on the diagnosis and treatment of multiple sclerosis.

Many symptoms are easy to be ignored, so the diagnosis of multiple sclerosis needs urgent attention.

　　Multiple sclerosis is a chronic and inflammatory demyelinating disease of central nervous system mediated by immunity. According to related research, the incidence and prevalence of multiple sclerosis are affected by geographical distribution and race. China is a low incidence area of multiple sclerosis, with an incidence rate of 0.235/100,000 people per year. At present, there are about 2.3 million patients with multiple sclerosis in the world. At the same time, multiple sclerosis is common in young adults, especially in women, and the number of patients is about three times that of men, so it is also called "beauty disease".

　　Up to now, there is no clear conclusion about the pathogenesis of multiple sclerosis, which may be related to many factors such as heredity, environment and virus infection. It is precisely because of the rarity of multiple sclerosis that the symptoms of the disease are very strange to the public in the early stage. The Survival Report of Multiple Sclerosis Patients in China, designed by Professor Yan Xu, Chief Physician of Neurology Department of Peking Union Medical College Hospital, shows that in 2019, 97% of patients with multiple sclerosis had never heard of multiple sclerosis when they were diagnosed.

　　Professor Yan Xu said: "Many patients may have symptoms in the early stage, but they didn’t realize that they had multiple sclerosis and went to the hospital. As a result, the median time from symptoms to diagnosis of multiple sclerosis in China was five years. If the patient begins to receive treatment within half a year of symptoms, the risk of entering disability in the future will be very low. "

　　Therefore, being alert to early symptoms will help the early diagnosis of multiple sclerosis. However, due to the diverse clinical manifestations of multiple sclerosis, common symptoms include decreased vision, diplopia, limb sensory disturbance, limb movement disturbance, ataxia, bladder or rectal dysfunction, etc., which also brings certain difficulties to the diagnosis.

　　Professor Chen Xiangjun, chief physician of the Department of Neurology, Huashan Hospital affiliated to Fudan University, said: "The initial symptoms of multiple sclerosis include suddenly being unable to see with eyes and feeling numb and weak on one side of the limb when walking, which is easy to be ignored. At the same time, there are some typical symptoms, such as ataxia, dizziness, unsteady walking, swaying, intonation when speaking, and involuntary eye tremor. It is also necessary to attach great importance to whether there is demyelination of the central nervous system when these symptoms appear. In addition, some symptoms are paroxysmal, such as instant headache or numbness of limbs, and uncommon symptoms such as cognitive dysfunction need to be vigilant. When these symptoms occur in young people, especially when these symptoms persist, you need to find a specialist doctor. "　

　　According to the latest data at home and abroad, the incidence and prevalence of multiple sclerosis are on the rise. In view of this phenomenon, Professor Qiu Wei, the chief physician of the Department of Neurology, the Third Affiliated Hospital of Sun Yat-sen University, explained it from three aspects: first, it may be because the prevalence and incidence of neuroimmune diseases, including other immune diseases, are increasing, which makes the prevalence and incidence of multiple sclerosis included increase; Secondly, it may come from the improvement of the diagnosis level of multiple sclerosis at home and abroad, and the support of new imaging technology and biomarkers for the diagnosis of multiple sclerosis. In addition, the public’s awareness of multiple sclerosis is also constantly improving, which makes more patients exposed, leading to an upward trend in the current incidence and prevalence data.

Make a targeted treatment plan to treat not only the "body" but also the "mind"

　　At present, multiple sclerosis can not be completely cured, but fortunately, there are already treatment programs around the world to effectively delay the progress of multiple sclerosis. In China, in recent five years, with the continuous improvement of domestic medical insurance policy and rare disease policy, more therapeutic drugs have been introduced from abroad, and the policy support for clinical treatment of patients with multiple sclerosis has been strengthened, greatly improving the accessibility of innovative drugs for multiple sclerosis in China.

　　With more and more therapeutic drugs, multiple sclerosis has gradually moved to the stage of self-medication and self-management, which makes it more important to choose a reasonable treatment plan. Only by choosing according to the course of disease, symptoms, adaptability and economic situation of different patients can patients benefit the most.

　　Professor Chen Xiangjun introduced that the treatment of patients with multiple sclerosis is divided into two stages: acute stage and chronic stage, and the treatment objectives of these two stages are different. In the treatment of acute phase, doctors need to quickly reduce the inflammatory process of immunity in vivo and reduce the damage of inflammatory process to the central nervous system as soon as possible. Chronic treatment, that is, remission treatment, is also very important. Because multiple sclerosis is a chronic disease process, it is necessary to choose appropriate disease adjustment and treatment drugs, that is, DMT (disease correction therapy) drugs.

　　"China’s emphasis on rare diseases has led to the introduction of many DMT drugs into China and is within the scope of medical insurance coverage. At present, some DMT drugs in China include common interferon beta, oral drugs, and antibody drug olfatomazumab. " Professor Qiu Wei introduced that olfatomuzumab has the characteristics of high efficiency and relative safety, at the same time, the dosage is accurate, which is beneficial to the treatment of multiple sclerosis in China to help realize the coverage and management of the whole population and the whole course.

　　Under the premise of medicine available, how to manage patients with multiple sclerosis at home has also become a common problem for doctors and patients. In the disease management of patients’ daily life, Professor Yan Xu suggested that, first of all, we should correctly establish the understanding of multiple sclerosis, not take it seriously, but not take it too seriously; Secondly, in terms of lifestyle, it is necessary to maintain the normal level of vitamin D, properly bask in the sun and supplement more dairy products; In addition, avoid smoking, control weight and keep proper exercise.

　　"In addition to paying attention to their own diseases, we also need to pay attention to the physical and mental health of patients, and finally achieve the goal of improving the quality of life of patients. Therefore, at the same time as drug treatment, symptomatic treatment is also needed. " Professor Chen Xiangjun emphasized that correct and active rehabilitation training is very beneficial to restore neurological function. Once there are obstacles in physical activity, or sensory obstacles, or obstacles in bladder and sphincter, we should actively seek correct rehabilitation treatment. Not only that, but also need to manage emotions.
