With the rapid development of digital technology, artificial intelligence is becoming a core competitive advantage in the field of education. Its iterative upgrading has not only brought revolutionary changes to teaching practice, but also brought unprecedented creativity to the education industry. Ms. Fan Bo, general manager of Aiqiyi Quanzhixin Education, pointed out: With the development of artificial intelligence, it marks that the field of education is moving towards a brand-new era.

　　First of all, in terms of teaching mode, the application of artificial intelligence is changing the traditional dual structure of "teacher-student" and introducing the ternary teaching mode of "teacher-student-machine". The support of intelligent teaching tools and platforms has become the key. These tools can not only provide personalized learning paths, but also provide accurate teaching feedback for teachers through data analysis, so as to realize personalized teaching, make up for the weak links of strengthening students and maximize the teaching effect.

　　Secondly, under the teaching mode of man-machine cooperation, the role of teachers is changing. They are no longer simple knowledge transmitters, but become the motivators of students’ learning internal drive, guiding students to explore the ocean of knowledge. At the same time, teachers have changed from the leader of the teaching process to the leader of the education process, helping students to build a knowledge system and cultivate their autonomous learning ability.

　　At the same time, students’ autonomous learning ability is particularly important in this process. With the great enrichment of educational resources and the expansion of educational space, students can study in a more diverse and open environment, which is no longer limited by traditional classrooms. The application of cognitive model has changed the way of knowledge production and knowledge dissemination, and brought far-reaching influence to the field of education.

　　Ubiquitous education has once again taken the lead in educational innovation by using artificial intelligence (AIGC) technology, and launched a series of cutting-edge courses, aiming at training students to master and apply the latest AI-generated content (AIGC) technology. The courses of "AIGC Design" and "AIGC Writing" under the company are well received. At the same time, based on the existing audio and video transmission technology and intelligent network, Universal Education innovatively launched a variety of online education products and services, including live broadcast, interactive live broadcast, recording and broadcasting, interactive recording and broadcasting, AR, VR, MR and so on. Reach more users quickly and accurately through the big data intelligent recommendation system.

　　Our "AIGC Design" course will teach students how to use AI tools for creative design, including graphic design, UI/UX design, animation production and other fields. The course covers the operation skills of AI design tools, the innovative application of design concepts, the acquisition of design core typesetting and color matching skills, the disassembly of aesthetic principles and practical cases, etc., in order to cultivate students’ innovative thinking and practical ability.

　　The course "AIGC Writing" emphasizes practicality and innovation, especially its application in content creation, copywriting and news editing. The course will introduce the use of AI writing tools, teach students how to efficiently generate texts with AI assistance, and at the same time emphasize maintaining the unique perspective and creativity of human authors to ensure the originality and attractiveness of the content. In addition, the course also focuses on the creation and incubation of personal brands, guiding students how to give play to their personal interests and hobbies through creative content output, establish and enhance their personal IP influence, and achieve creative efficiency and dimension improvement, thus realizing more possibilities for self-media sideline and new careers. The project also won the award of "China Science and Technology Innovation Enterprise of the Year in 2023 -AIGC" in the new economic peak list of Ai Media, which is also a high recognition of the achievements of Universal Education in the field of AIGC.

　　Universal education has always been committed to promoting the development of education through technological innovation, which not only responds to the demand for updating educational content in the digital age, but also provides students with the necessary skills to adapt to the future workplace and increase their competitiveness in their careers.

　　In the future, Ubiquitous Education will continue to explore the deep integration and application of artificial intelligence technology and educational practice, provide students with more high-quality learning resources, and constantly promote the innovation and upgrading of education and teaching with the "golden key" of artificial intelligence.

　　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.

　　Recently, this year’s perfect composition "Living in a Tree" in Zhejiang College Entrance Examination triggered a hot discussion among netizens, and Chen Jianxin, the leader of the composition marking group of Zhejiang College Entrance Examination and an associate professor of Zhejiang University, received attention. Some netizens pointed out that Chen Jianxin was the editor-in-chief of the college entrance examination composition teaching aid book, and gave many lectures on college entrance examination composition teaching, and questioned Chen Jianxin’s "abuse of power for personal gain".

　　In this regard, the survey in The Paper found that Chen Jianxin had edited two supplementary books on composition for college entrance examination in 2016 and 2019, and gave lectures on "Intensive Training Course on Composition for College Entrance Examination" through Tencent Classroom, Qingyun Duan Micro Classroom, Southern Academy and other platforms, with a price of 199 yuan. In addition, he has given many lectures on composition for teachers and students in Zhejiang Province.

　　Is Chen Jianxin’s behavior illegal or "abusing power for personal gain"? When interviewed by The Paper, many education experts said that it is necessary for Zhejiang Education Examinations Institute to answer and decide whether college entrance examination examiners edit relevant books and give lectures in violation of regulations.

　　Recently, The Paper repeatedly called the Scientific Research and Publicity Department of Zhejiang Education Examinations Institute, but no one answered the phone.

　　With regard to a series of discussions triggered by the perfect score composition of Zhejiang college entrance examination, many education experts also mentioned that further education reform should be carried out to change the way of education evaluation.

　　Editor-in-chief of the college entrance examination composition teaching assistant, lecturing on the "intensive training course of college entrance examination composition" for 199 yuan.

　　The Paper noted that Chen Jianxin had participated in the editing of two supplementary books on college entrance examination composition, namely, Selected Comments on Essays published by Zhejiang Education Publishing House in 2016 and Practical Training on College Entrance Examination Composition published in 2019. At present, these two books are sold on multiple e-commerce platforms.

　　In a shop of an e-commerce platform, the introduction of "Selected Comments on Discourse Articles" shows that Chen Jianxin, the editor-in-chief of the book, is priced in 30 yuan, and the content is divided into five parts; The latest revised edition published in 2017 added the "2017 college entrance examination composition marking standard" and "selected more than 20 examination room compositions and authentic comments".

　　According to the information of another store on the above-mentioned e-commerce platform, one of the two editors of the College Entrance Examination Composition Practical Training is Chen Jianxin, whose price is 59 yuan, and the designated purchase method is "Xinhua Bookstore in Zhejiang Province". The book also contains full-score compositions and comments from the college entrance examination.

　　In addition, Chen Jianxin’s "Intensive Training Course of College Entrance Examination Composition" was launched on Tencent Classroom, Qingyun Micro Classroom and other platforms, and was promoted through the media platform in late April 2019.

Screenshot of the related publicity page of "College Entrance Examination Composition Intensive Training Course" by Chen Jianxin.

　　The poster of this course is written with the words "2019 College Entrance Examination Composition" and "College Entrance Examination Composition Intensive Training Course for Candidates by College Entrance Examination Marking Teachers". According to the lecturer, Chen Jianxin has been the leader of the composition marking group of Zhejiang College Entrance Examination since 2000, presiding over the composition marking work of Zhejiang College Entrance Examination every year, and evaluating the perfect composition every year. The introduction of the course features in the poster also emphasizes "the head of the college entrance examination marking team and the famous marking teacher personally teach", "accurately coping with the scoring points of the college entrance examination composition" and "writing skills that can be directly applied to the examination room composition".

　　According to the information in the publicity page, the "2019 College Entrance Examination Composition Intensive Training Course" was created by Zhejiang Education Publishing Group, with a total of 18 sessions, including the college entrance examination composition marking and high score points, examination, conception, breakthrough in essay writing, and the use of words and phrases. The online course is priced at 199 yuan in Tencent classroom and Southern Academy platform.

　　In addition, Chen Jianxin has given lectures on composition for college entrance examination for Zhejiang teachers and students for many times.

　　Official website, Education Bureau of Huzhou City, Zhejiang Province, shows that Chen Jianxin gave a special lecture on composition for the 2019 college entrance examination for all senior high school teachers in Deqing County in March 2019 in Deqing No.1 Middle School of Huzhou. Official website, the People’s Government of Cangnan County, Zhejiang Province, shows that Chen Jianxin participated in the "On-the-spot Meeting of Writing Guidance for Senior High School Chinese College Entrance Examination" hosted by Cangnan County Education Bureau in March 2018, giving lectures on composition guidance for nearly 200 senior high school Chinese teachers. Official website of Hangzhou Xuejun Middle School in Zhejiang Province showed that Chen Jianxin had given a lecture entitled "How to write a good exposition article" at the school in April 2017, and the audience was all senior three students of Hangzhou Xuejun Middle School.

　　On the morning of August 10th, according to the report of The Paper, Chen Jianxin responded that he was "unclear" about compiling teaching AIDS for college entrance examination composition.

　　Whether the relevant behavior is illegal or not needs to be answered by Zhejiang Education Examinations Institute.

　　In the past few days, the concern aroused by the perfect score composition of Zhejiang college entrance examination has shifted from the discussion on the text of Living in a Tree and whether the full score given by the composition is reasonable to the disclosure of the marking situation by the head of the Chinese marking group of the college entrance examination, the editing of the teaching aid book of the college entrance examination composition, and whether the intensive training courses and lectures on the college entrance examination composition are in compliance and whether it is suspected of abusing power for personal gain.

　　In this regard, on August 10th, Chen Zhiwen, editor-in-chief of China Education Online, said in an interview with The Paper that there was no room for discussion about how to judge the perfect composition in Zhejiang College Entrance Examination. "In fact, foreign exams such as TOEFL, IELTS SAT, GRE, etc., candidates need to sign a statement on the transfer of rights before the exam. The core meaning is that right or wrong is determined by the organizers of the exam, not by people including candidates." Chen Zhiwen said.

　　He believes that among the concerns caused by the perfect score composition of Zhejiang college entrance examination, the only point worth discussing is: Who pushed a topic that is not suitable for discussion in the public opinion field to the public opinion field?

　　On August 5th, Wen Rumin, editor-in-chief of Chinese textbooks for primary and secondary schools hired by the Ministry of Education, pointed out in the Weibo that the marking of the college entrance examination should be kept confidential, and all participants in marking should not disclose the marking situation to the outside world, and bluntly said, "It is illegal to disclose the Zhejiang perfect score composition in the journal for the first time."

　　In addition, on August 10th, Chu Zhaohui, a researcher at the Chinese Academy of Educational Sciences, told The Paper that it was definitely not suitable for the group leader of Chinese composition marking in the college entrance examination to write and publish the college entrance examination composition guidance book and give lectures on composition guidance.

　　In this regard, Chen Zhiwen said that, unlike the proposer, the management of college entrance examination examiners is relatively not too confidential. Therefore, whether it is illegal for college entrance examination examiners to go out to give lectures and publish some related books requires the relevant departments of various provinces to answer and decide.

　　Similarly, Xiong Bingqi, president of the 21st Century Education Research Institute, pointed out that it is not rational to discuss the issue just because Chen Jianxin published books and participated in lectures. Whether there is any act of illegally seeking personal gain by using the identity of the group leader of Chinese composition marking in Chen Jianxin requires the involvement of relevant departments in the investigation.

　　An education expert who did not want to be named bluntly said: "Zhejiang Education Examinations Institute has the responsibility to stand up and respond to public questions."

　　Expert: The entrance examination should be changed from "selection" to "evaluation"

　　Xiong Bingqi believes that it is impossible for the examiners to disclose the college entrance examination questions, and it is not against the regulations to interpret the marking standards for serving candidates, with the leader of the marking group as the editor-in-chief and publishing books on composition guidance.

　　Chu Zhaohui, on the other hand, said that Chen Jianxin is not alone in publishing books and giving lectures by examiners in the college entrance examination. Some training institutions still use examiners to conduct commercial speculation. He believes that this kind of situation has both loopholes in the system and lax management, so it is necessary to improve the system and strengthen management.

　　In addition, Chen Zhiwen believes that the statement that "Chen Jianxin has been the head of the Zhejiang College Entrance Examination Chinese composition marking group since 2000 and presided over the annual Zhejiang College Entrance Examination composition marking work" needs to be verified by the authorities. "There are still many people who claim to be the leader of the proposition, or the proposer. Can you believe it?" Chen Zhiwen said.

　　Talking about a series of discussions triggered by the perfect score composition of Zhejiang College Entrance Examination, Chu Zhaohui and Xiong Bingqi both mentioned the need for further education reform.

　　Xiong Bingqi pointed out that the focus of the contradiction lies in the fact that the college entrance examination is a selection test, not an evaluation test. The so-called selection test is to select candidates fairly, and it doesn’t matter whether the selection system is scientific or not; The evaluation test, on the other hand, is to pass the test to evaluate students’ mastery of real subject knowledge and subject accomplishment.

　　He believes that it is difficult to solve the problem of exam-oriented composition atmosphere through marking. "To improve the quality of composition proposition and reading, further improve the quality of Chinese education, and the quality of education in all subjects, we need to promote the reform of the examination enrollment system and effectively change the entrance examination from ‘ Selection ’ , the reform is ‘ Evaluation ’ . Otherwise, the controversy surrounding the proposition and marking is just ‘ Chicken feathers in one place ’ 。”

　　Chu Zhaohui believes that the controversial issue reflects from a deeper level that the current enrollment examination program design is not standardized and professional. "In a more standardized and professional procedure, the questioner doesn’t have to write the questions in a closed environment, and the questions need to go through multiple procedures and various tests before ‘ Out of the oven ’ ; In the marking session, it will not be determined that a certain person will be the team leader for a long time. " Chu Zhaohui said.

　　"There is still a long distance between the professionalism and modernity of the college entrance examination enrollment process and modern education evaluation." Chu Zhaohui, for example, said that some foreign exams judged that candidates cheated, not because they caught the candidates plagiarizing in the examination room, but because they initiated the analysis of the answer results, and if the analysis results showed that some answers reached a certain similarity, they were considered cheating.

　　In this regard, Chu Zhaohui’s idea can allow ordinary colleges and universities to use students’ academic performance in high school as the basis for enrollment, thus narrowing the scope of the college entrance examination. In this way, the workload of marking and evaluating the college entrance examination is relatively reduced, and it is possible to analyze and evaluate the results of the college entrance examination according to different levels, to reverse the problems of exam-oriented teaching and routine answering, and to promote the specialization and modernization of educational evaluation.

　　In the 2008 Beijing Olympic Games, Phelps’ eight gold medals broke the 36-year-old record that was once considered inaccessible by swimmer Mark Spitz. Phelps participated in men’s 400m individual medley, men’s 200m individual medley, men’s 100m butterfly, men’s 200m butterfly, men’s 200m freestyle, men’s 4x100m freestyle relay, men’s 4x200m freestyle relay and men’s 4x100m medley relay successively at the Beijing Olympic Games, winning eight gold medals, breaking seven world records, and gaining fourteen individual medals. Phelps set an insurmountable record for others. China News Agency issued Du Yang photo

This is also the first time that a male athlete from China has won an Olympic medal. China News Agency issued Du Yang photo

　　BEIJING, Aug. 16 (Xinhua) Title: Swimming Inventory: The United States and Australia are "gender imbalance" and the China Navy is no longer "water"

　　Author: Lu Chunyan

　　On August 17th, "prodigy" michael phelps led the American team to win the gold medal in the men’s 4×100 medley relay final, and won his eighth gold medal in Beijing. This marks the end of the swimming event in Beijing, which is second only to the 46 gold medals in track and field. The "Water Cube" of this Olympic Games has turned into a "Water Cube", and the world record has been labeled as "fragile". The United States and Australia have their own gains in competing for hegemony, and the China Navy has also seen hope in its progress.

　　"Yang Prosperity and Yin Decline" VS "Yin Prosperity and Yang Decline" The United States and Australia strive for hegemony and "gender imbalance"

　　Compared with the Athens swimming event, the gorgeous performance of the American swimming team in the Water Cube can be described as "dominating the world". The results of 12 gold medals, 9 silver medals and 9 bronze medals left Australia’s 6 gold medals, 6 silver medals and 8 bronze medals far behind.

　　However, Australia, suppressed by the United States, should also be respected. After all, today’s swimming world has the strength to challenge the American team, and it is Australia. The remaining 14 gold medals were divided among 11 countries, with Britain, Germany and Japan each taking two, and China, Brazil, Tunisia, South Korea, the Netherlands, Italy, France and Zimbabwe each taking one.

　　The distribution of gold medals in the American swimming delegation showed a situation of "Yang flourishes and Yin declines". Male athletes won 10 of the 12 gold medals, and they monopolized five-eighths of the Olympic men’s swimming events under the leadership of Phelps. Only coughlin and Sony saved a little face for American female swimmers.

　　Unlike the United States, which relies on men’s events, Australia has completely embarked on the "female route". All six gold medals in the "Water Cube" were won by female athletes, while male athletes only got three silver medals and three bronze medals. Compared with the American team, Australia’s "Yin flourishes while Yang declines" seems to be more thorough.

　　"Yin flourishes and Yang declines" VS "Yang flourishes and Yin declines", and there is a gender imbalance between the United States and Australia. In August, a gender war was staged at the National Aquatics Center.

　　World records are labeled as "fragile" and old records are turned into rarities.

　　The Water Cube staged a "war epic" against the "world record" from the first match day when two world records were born in the four finals. Seven of the eight gold medals won by the American "prodigy" rewrote the world record, and even the only gold medal in the 100m butterfly, which was "lighter" than the other seven gold medals, was almost the same as the world record. What’s more, Zimbabwe’s Coventry started a record-breaking trip in the preliminaries.

　　The birth of one new world record after another makes the audience seem to have formed "aesthetic fatigue" on the records, and a large number of newly released records really test everyone’s memory. All of a sudden, those records that have been preserved have become rare, and they can still be "immune" when such large-scale good results are released, which shows the preciousness of these old records.

　　Men make history. China swims in the "Water Cube" and sees hope.

　　China swimming, dormant in the downturn, finally saw the hope of recovery in the "Water Cube". One gold, three silvers, two bronzes, three 4th, one 5th, one 7th and one 8th in this Olympic Games are enough for China to get a performance score of 80 points. All these have become the best evidence that Zhang Yadong, the head coach, pointed out that China Water Army began to walk out of the trough.

　　Liu Zige, Jiao Liuyang and other young players have changed the situation in 2007, and Zhang Lin’s silver medal has also shown us the progress of male athletes.

　　The most significant one is the silver medal in the men’s 400-meter freestyle from Zhang Lin. Even in Barcelona, the most splendid swimming place in China, the male swimmers from China failed to grab a gold and a half silver. Zhang Lin won the first medal in Olympic history for men’s swimming in China with his own efforts and national support.

　　However, we should also see that China’s swimming strength is still far from the collective advantage of the United States and Australia, and the highlights are only concentrated in three or two events. Moreover, China’s swimming does not have the domineering and winning strength of the United States and Australia.

　　However, I still believe that "a single spark can start a prairie fire", and I hope that China Swimming, which finds a breakthrough point, can make a name for itself in the Olympic swimming field through its own efforts.

　　"God" Phelps, the first man in the centennial Olympic Games, ascended the throne in Beijing.

　　After winning the NBA championship three times in a row, the media commented that "Jordan is God wearing a jersey and playing"; Once again won the NBA championship for three consecutive times, the media commented that "even God can’t beat Jordan in his jersey". Therefore, even with bare arms, God may not be able to win eight gold medals in an Olympic Games, but the "prodigy" did it.

　　Michael phelps seems to have come to Beijing to break the record. He has seven world records in eight competitions, a single Olympic gold medal record with eight gold medals and an individual Olympic gold medal record with fourteen gold medals. Phelps is proving himself to be the "Water Cube" and the king of Olympic history with figures that others can’t match.

　　When Bolt broke the world record and won the 100-meter new Olympic champion, the media who liked the new and hated the old questioned the ownership of "the best athlete in Beijing Olympic Games". In fact, this is a very simple arithmetic problem. Can’t nine records beat one record? The record of eight gold medals of "prodigy" was accumulated in the Olympic Games for a hundred years, but who can say that the record road of 9.69 seconds can be kept fresh in a hundred years?

　　For 23-year-old Phelps, the Beijing Olympic Games is probably just a "walk" of his brilliant career, because he will be 27 years old in four years, which is the best age for professional athletes. At that time, he will give the world the expectation of several Olympic gold medals. (End)

　　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.
