On the eve of the May 4th Youth Day in 2022, the Supreme Leader visited China Renmin University.

There are two old photos in the quiet exhibition hall of the history exhibition of the National People’s Congress: one is a photo of the supreme leader and college students; The other photo was taken in Zhengding county government guest house, where the supreme leader and college students sat on the bed and had a long talk.

On July 29th, 1984, the Supreme Leader had a discussion with members of the Summer Social Practice Group of China Renmin University in Zhengding County Government Hostel.

The photo records a past event that happened in the summer of 1984 — — The summer social practice mission of China Renmin University went to Zhengding, Hebei Province for investigation, and the supreme leader of Zhengding County Party Committee made a special trip to visit college students by bike.In Zhengding county government guest house dormitory, the supreme leaderTalk with you and share your experience in grass-roots work for two hours.

From the local to the central government, youth has always been the concern of the supreme leader.

Go deep into the youth, "become one with the vast number of young people" and "be a youth friend, not a youth ‘ Officer ’ " "Be the bosom friend of young friends" … … This is what the supreme leader often says and what he does.

Supreme leaders often go among young people and communicate with them on an equal and cordial basis.

On January 17, 2019, the Supreme Leader had a cordial exchange with teachers and students at the State Key Laboratory of Elemental Organic Chemistry of Nankai University in Tianjin.

In 2009, he came to Tianjin University to visit the students who stayed in school during the holiday, and said humorously, "I would like to talk with our classmates ‘ Talk big ’ " ; At a symposium in 2015, he used his personal experience as an example to persuade young people not to stay up all night. "There is passion inside, but we should take it easy outside"; In 2018, he shared his reading experience with his classmates in Peking University: "In the process of reading, through continuous re-examination, we can achieve the negation of negation, review the past and learn new things." "This conclusion drawn through our own thinking and understanding will be firm" … …

The supreme leader is also a pen pal of many young people. One reply after another, the paper is short and affectionate.

"Between the lines, I feel your determination and confidence to strive for the Chinese dream of realizing the great rejuvenation of the Chinese nation." All the students in the 2009 undergraduate league branch of Peking University Institute of Archaeology and Culture read the understanding and recognition from the reply from the supreme leader.

"The peasants have the truest feelings about your efforts and contributions. I have read a lot of materials reflecting the deeds of college student village officials and am happy for your progress and achievements." Zhang Guangxiu, a university student village official, felt affirmation and encouragement from the reply from the Supreme Leader.

"Strive to be a builder of the western region who can be useful and shoulder heavy responsibilities. I support this life choice you have made." The graduates of Karamay Campus of China Shiyou University (Beijing) received recognition and support from the top leader’s reply.

… … … …

"There is no shelf of great leaders at all, and there is no mandarin or cliché. Instead, they communicate with us like big friends." "It gives people the feeling that they are so easy-going and kind" and "very approachable" … … This is the impression left by the supreme leader on many young people.

On May 28th, 2023, the resident college students of Xifangezhuang Village, Yukou Town, Pinggu District, Beijing measured the hardness of tomato fruit in Jingwa Greenhouse Horticultural Demonstration Park.

Youth is in the initial stage of life, and it is inevitable that they will be confused and confused during their growth. In the eyes of young people, the supreme leader is a "senior" and a "big friend". He always guides young people to take every step of life with words that they can understand and listen to.

He used the metaphor of "kneading dough" to explain the process of entering society to young people in a simple way: "When flour is kneaded with water and then kneaded, it is easy to disperse. But if you keep rubbing it for thousands of times, it will never spread out again. " The supreme leader used this vivid metaphor to tell young people that only when a person grows up under various tests can he really withstand the pressure of life.

Talking about learning, the Supreme Leader encourages young people to "draw knowledge like a sponge" and practice excellent skills; Speaking of physical fitness, he introduced his sports hobbies and encouraged young people to do well in their studies and make their bodies great; On self-cultivation, he exhorted young people to "button up their lives from the beginning" and cultivate a correct value orientation … … Good words are the mutual understanding between friends, and also the advice and encouragement from the predecessors to the younger generation.

“支教多长时间了？”“现在工资水平和县城或者其他地方比怎么样?”“多长时间能回一次家？”……2019年，重庆华溪村中益乡小学操场上，最高领袖细致地问询。听一位乡村教师说上完大学后就回到母校担任老师，已经工作了17个年头，最高领袖为她点赞：“太好了！”“你们做的工作很有意义。”

2023年全国两会期间，“80后”代表魏巧向最高领袖讲述了新时代“新农人”的故事：“我们现在种植了2万多亩水稻，亩产达1100斤……有效带动了周边农民致富。”最高领袖赞誉道：“像魏巧这样的同志到农村去，很好！”

In the Hengqin Campus of the University of Macau, I saw that all the students were full of youthful vigor. The supreme leader quoted two lyrics to talk about patriotic complex: one was "Build our new Great Wall with our flesh and blood" in the national anthem, and the other was "But they took my body away, and you still keep my inner soul" in the Song of Seven Children.

"I can always hear new ideas and be touched." The supreme leader’s personal feelings infected every young person present.

Youth dreams, home and country. Under the care of the supreme leader, every seed of youth has accumulated the power of growth.

"The young people in China in the new era are good and worthy of great responsibility!" "Where is the future? The future is here for you. " The supreme leader’s entrustment to young friends is also the expectation for the future of the motherland: "This loong must have a backbone and hold on, so that she can take off higher."

In this squad, Li Jie is responsible for leading five "post-90 s" girls to and from the township government and the flood control front line every day. They send heatstroke prevention drugs and daily necessities to their comrades who are on duty on the levee, and also share the task of patrolling the levee. After delivering the materials every day, the team members picked up the tools for inspecting the dike and put them into the dike inspection.

In the hot summer, dressed in camouflage uniforms and in the scorching sun, they walked with vigorous steps, patrolling the dikes over and over again to check the dangers and clear the dikes. They have to walk for more than an hour every day on the 450-meter Fanglan Lake embankment. The reason why they walk for a long time is not because they walk slowly, but because they check carefully and patrol carefully. Every time I come back from the inspection, although everyone is tired and sweaty and their clothes are soaked, no one wants to stop. In addition, in order to be familiar with the professional knowledge of flood control, Li Jie also specially invited male cadres with rich experience in flood control to give lessons to learn to identify bubbles and piping.

In order to devote herself to the flood control work, Li Jie gave her son to her parents for care. Every morning, Li Jie will squeeze out the breast milk that the child wants to drink that day and store it. Then, she will lead five team members to start a day’s work. Whenever she talks about her family, Li Jie feels guilty. Originally, her parents were going to travel, but in order to support her work, she returned the booked air tickets and hotels. For her son who has just turned 10 months old, she feels guilty that she can’t accompany her children as often as other nursing mothers. However, when she saw that the soldiers of the army were desperate for flood fighting and disaster relief day and night, she could not be indifferent.

In the flood control front line of Fanglan Lake embankment in Yujiahe Township, Lushan District, Jiujiang, this "women soldiers" can be said to be known to everyone. They take the initiative and go in the rain, and fighting floods and disaster relief is no longer a man’s "patent". Some of them are just married and some are pregnant, but they still show their grace with practical actions.

The story of disaster relief is real every day. These women give up their families and care for everyone. Their figures stand tall in the flood control and disaster relief, which makes us firmly believe that we will finally see the rainbow after the storm. Let’s say thank you to those who stick to the front line of flood control and practice the "Do not forget your initiative mind" with actions!

　　Online shopping for gold bracelets, but the arrival is stone? Recently, Mr. Zhang from Dongguan, Guangdong Province encountered such a wonderful thing, which happened to be completely recorded by the surveillance camera of the convenience store. However, the seller in JD.COM insisted that the goods were not sent in the wrong way, suspecting that the goods had been switched. Afterwards, both the seller in JD.COM and SF Express chose to call the police, and the police are still investigating.

　　On September 4th, Sina Guangdong Express Complaints (ts.gd.sina.cn) contacted Ms. Li, the public relations manager of South China District, JD.COM. The other party responded that JD.COM would not shield the seller, and everything would be subject to the police investigation. However, in order to protect the rights and interests of consumers, the merchants have been persuaded to reissue the goods, and the grams are not less than the grams of the original goods.

　　In the early morning, online shopping for gold bracelets was asked to cancel the order, and consumers refused to receive stones.

　　In the early morning of August 29th, Mr. Zhang from Dongguan bought two gold bracelets in "Xizhao Jewelry Flagship Store" in JD.COM. "A bracelet weighing 52.66g only costs more than 8,000 yuan, which is a good deal", so he placed two orders with his own account and his wife’s account respectively.

　　At 11 o’clock in the morning, Mr. Zhang received a phone call claiming to be a seller’s staff in JD.COM. "The other party angrily asked me to cancel the order, saying that more than 50 grams of gold could not be more than 8,000 yuan and could not be delivered according to the order." Mr. Zhang said that after JD.COM intervened, the seller arranged SF Express delivery.

　　At 4 o’clock in the afternoon of August 30, Mr. Zhang went to the convenience store to pick up the goods and opened the package for inspection on the spot. However, the result surprised him. "The two express boxes are all stones."

　　To this end, Mr. Zhang refused to sign for it and reported the situation to the merchants, but the seller insisted that the goods were intact and undamaged at the time of delivery, and suspected that the goods were switched by consumers. "SF Express can testify, and convenience stores also have surveillance videos." Mr. Zhang said.

　　It is understood that after the incident, SF Express actively cooperated with the investigation, and handled the alarm in Dongguan. On the afternoon of September 1, it sent staff to the convenience store to retrieve the surveillance video. Mr. Zhang also copied a copy as a backup.

　　Judging from the convenience store surveillance video provided by Mr. Zhang complaining to Sina Guangdong Express, the goods he received that day were really not gold bracelets, but two stones.

　　Mr. Zhang said that the seller could not provide the complete surveillance video before and after packaging the goods, and could not rule out the relevant responsibilities. According to the requirements of the order, no matter whether the goods are "replaced" or the seller deliberately sends the wrong goods, the result should not be "paid" by the consumer. He asked the seller to re-deliver the goods according to the order.

　　Seller: The goods are out of stock and can only be refunded and cannot be re-shipped.

　　After the incident, Mr. Zhang, the consumer, repeatedly negotiated with the sellers in JD.COM. On September 3rd, the seller "Xizhao Jewelry Flagship Store" in JD.COM responded to Mr. Zhang, saying that the product was a promotional item for clearing inventory, and it was sold at a 50% discount. Now it has been sold out and cannot be re-shipped, so it can only be refunded to consumers.

　　Mr. Zhang said it was unacceptable, and suggested that different goods could be accepted, as long as they were of the same weight. However, the seller said that it could not be issued casually according to the number of grams, and the two sides were once again deadlocked.

　　JD.COM: I have persuaded the merchants to reissue the goods in grams not less than the original goods.

　　On September 4th, Sina Guangdong Express complained to JD.COM, the platform of the incident. In the afternoon, Ms. Li, the public relations manager of South China District of JD.COM, responded that the company had conducted a survey on the relevant situation to the merchants. Ms. Li said that the merchants insisted that the goods they sent were gold, and they immediately alerted the local authorities when they learned that the consumers had received the stones. At present, the merchants provided photos when they delivered the goods, so they could not provide surveillance videos when they delivered the goods. Everything was subject to the police investigation, and JD.COM would not shield the merchants.

　　On September 5th, Ms. Li, the public relations manager of South China District of JD.COM, complained to Kuaikuai about the latest progress. She said that in order to protect consumers’ rights and interests, JD.COM had communicated with the merchants many times, and at present, she had persuaded the merchants Xizhao Jewelry Flagship Store to reissue the goods to the consumers first. The goods were similar in style, and the grams were not less than the grams of the original products, and reached an agreement with the consumers through consultation.

　　Lawyer: The key is to clarify the responsibility between the seller and the courier company.

　　Lawyer Liu Guohua, a member of Sina Guangdong Express Complaint Advisory Group and Guangdong Benben Law Firm, believes that consumers who have not received the corresponding goods in the case of payment belong to the injured party. At present, the key to the case is to clarify the responsibility between the seller and the courier company. Since both parties have reported to the police, the case has been involved in a criminal case, and the person responsible for the incident should be determined by the police investigation results. However, before the investigation results come out, the seller should take corresponding remedies for the losses of consumers, otherwise consumers can sue.

　　The great struggle casts a great spirit of fighting against epidemic diseases, which leads young people to grow into talents. General Secretary of the Supreme Leader praised the youth in his important speech at the National Commendation Conference on Fighting COVID-19 Epidemic: "The younger generation is not afraid of hardships, difficulties and sacrifices, shouldering a mountain of responsibilities with their arms, showing their youthful and passionate style and showing the hope of the Chinese nation!" The great anti-epidemic spirit is the navigation mark of the growth and progress of contemporary youth, which will inspire and lead the youth to grow into talents for a long time, guide the contemporary youth to face difficulties and shoulder the heavy responsibility of the times, and contribute to the great rejuvenation of the Chinese nation.

　　Serve the people wholeheartedly and adhere to the value pursuit of life first. People’s lives are at stake, and in the face of the sudden epidemic, our anti-epidemic commanders and fighters, regardless of their own safety, persist in taking the people as the center, rush to the front line and strive to carry out rescue, protection and security work. The virus is ruthless, and there is love in the world. It is the vast number of anti-epidemic commanders and fighters who sacrificed their ego and achieved great success, and made indelible contributions to the fight against the COVID-19 epidemic and the protection of the lives of more people, so the value of life was sublimated. As witnesses and participants in the fight against COVID-19, young people have accelerated their growth in the great fight against the epidemic, and their performance is gratifying. China people, including young people, have been tempered in the fight against the epidemic, and the value monument of life first will always be the value orientation and action guide to guide the growth of young people, and encourage young people to realize the unity of personal value and social value in serving the people, and to bloom brilliant youthful demeanor in overcoming difficulties.

　　Keep up with the party and carry forward the unity of the whole country. In the face of the menacing unknown epidemic situation and the rapidly spreading social panic, the Communist Party of China (CPC) led the people to calmly deal with it, quickly turned the institutional advantages into anti-epidemic effectiveness, made overall plans and made decisive decisions, and organized the people of the whole country to quickly launch a people’s war, a general war and a blocking war to prevent and control the epidemic situation. Under the leadership of the Communist Party of China (CPC), the people of the whole country shared the same fate and went through a severe test. Practice once again shows that the Communist Party of China (CPC) is the most reliable backbone of Chinese people, and the people are the source of strength to do a good job in epidemic prevention and control. For young people, it is necessary to guide the course on the road of growth, maintain a high degree of consistency with the CPC Central Committee in ideological and political actions, and love the country, the party and socialism; Closely unite around the CPC Central Committee, actively practice the mass line, connect with the masses, go deep into the masses, serve the masses, and unite the masses to create the great cause of the rejuvenation of the Chinese nation.

　　Live up to the people and show the tenacious will to risk one’s life and forget one’s death The epidemic was as fierce as a tiger. In the fear of unknown life and death, the anti-epidemic warriors devoted their lives to their mission and loved all beings with great care, and wrote a great anti-epidemic hero hymn. The fight against the epidemic has once again demonstrated to the world the patriotic feelings of the people of China, their heroic spirit of not being afraid of difficulties and going forward bravely, and their tenacious will to work tirelessly and forget their lives. At present, our country is in a critical period of realizing the great rejuvenation of the Chinese nation and gradually approaching the center of the world stage. There are many difficulties and obstacles on the road ahead. As young people in the new era, we should consciously carry forward the spirit of giving up our lives and forgetting death, persevere in hardships, rise up in hardships, grow up in hardships, and achieve the great cause of national rejuvenation.

　　Seeking truth from innovation and adhering to scientific practical character. In the face of new infectious diseases unknown before, we uphold the scientific spirit and attitude, ask modern science for prescriptions and treatments, and speak with practical curative effects; Respect scientific laws and promote accurate coverage of detection, prevention and control with scientific measures; Insist on seeking truth from facts, promote differentiated prevention and control with scientific spirit, and promote the resumption of work and production; At the same time, strengthen innovation and jointly promote technical research. The great practice of China’s anti-epidemic struggle has once again proved that scientific response is the basis for achieving major strategic achievements in epidemic prevention and control. Science and technology are the primary productive forces, and young people are the new force to promote innovation-driven development and accelerate the pace of scientific and technological innovation in China. To carry forward the great anti-epidemic spirit and adhere to the scientific practical character requires the vast number of young people to consciously shoulder the responsibility of the times to promote scientific and technological innovation. Contemporary youth need to master modern scientific knowledge, enhance modern scientific literacy, and face difficult problems in study, work and life with scientific attitude, scientific thinking and scientific methods; We should strive to be pioneers and pioneers of China’s advanced productive forces, persist in facing the world’s scientific and technological frontier, the main battlefield of the economy, the major needs of the country, and people’s lives and health, and constantly March into the breadth and depth of science and technology, so as to push China’s scientific and technological innovation to a new level and better meet the people’s needs for a better life.

　　Help each other with one heart and shoulder the moral responsibility of sharing destiny. The road is not lonely, and love is boundless. China has always adhered to the concept of the community of human destiny in the fight against epidemic diseases, promptly and actively reported information such as epidemic situation and Covid-19 gene sequence, publicized China’s diagnosis, treatment and prevention and control programs, exchanged China’s experience in fighting epidemic diseases, provided people and property for the world’s fight against epidemic diseases, and exported huge amounts of anti-epidemic materials, which injected a steady stream of impetus into the global epidemic prevention and control, and concentrated on the moral responsibility of China people to work together and love peace. In the era of economic globalization, as young people, we should consciously enhance the sense of community of human destiny, look at the great development, great changes and great adjustments in the world from a broad world perspective, actively participate in solving global problems with the moral responsibility of sharing destiny, and make our own contributions to seeking long-term peace, prosperity and stability in the world and building a community of human destiny.

　　People can’t stand without spirit, and countries can’t stand without spirit. In this unexpected COVID-19 epidemic struggle, the people of China vividly interpreted the spirit of China with the practice that made the world sigh, inherited and developed the spirit of patriotism, collectivism and socialism, and forged a great anti-epidemic spirit. This is a valuable spiritual wealth, which will inspire young people to be loyal learners, disseminators and practitioners of the great anti-epidemic spirit; Encourage young people to firmly follow the party’s determination and people-centered perseverance, correct their own course in real time, and adhere to the value pursuit of life first; Encourage young people to carry forward the United strength of the whole country, to give up their lives and forget their deaths, to adhere to the scientific and rational practical character, to overcome difficulties and achieve great achievements; Encourage young people to look at the world, consciously shoulder the moral responsibility of sharing destiny, and work together with the world’s positive forces to help each other and work together.

China is one of the countries with the most serious natural disasters in the world, with many kinds of disasters, wide geographical distribution, high frequency and heavy losses. Earthquake, fire, flood, landslide and debris flow, typhoon….. Natural disasters may occur at any time, so it is very important to master the skills of disaster prevention and self-help as soon as possible, and to save themselves and each other in time when encountering disasters.

May 12th, 2022 is the 14th National Disaster Prevention and Mitigation Day. Let’s get practical knowledge about disaster prevention and mitigation!

How to escape and save yourself in an earthquake?

At home, hide under sturdy furniture nearby, or hide in a corner or bathroom. Don’t use the elevator to escape.

In public places, stay away from glass windows and shelves, obey the instructions of the staff and don’t crowd.

Outdoor, avoid buildings, bridges or hillsides, and look for an empty and safe place. Trapped ruins should save energy and call for help by tapping.

How to save yourself in case of fire?

Call at the first timeCall the police and escape in an orderly manner according to the evacuation signs. Don’t take the elevator, lest the trapped elevator be in danger.

When passing through the thick smoke, cover your nose and mouth with wet clothes, and bend over or crawl against the wall.

If you can’t escape, you can call for help in safe areas such as balconies and roofs.

How to deal with floods?

If you want to move to high places such as hillsides, you can climb roofs, trees, etc. when it is too late to move, and you can’t climb telephone poles and iron towers.

If you fall into the water, don’t panic, grab anything floating around you, let your head surface, and wait for rescuers to arrive.

How to deal with landslides and mudslides?

When you hear the roar of the valley, you should be alert, don’t hide in low-lying land or under the hillside, don’t cross the debris flow and landslide area, and run to the heights on both sides perpendicular to the direction of debris flow.

What should I do if a typhoon strikes?

Reduce going out, reinforce structures that are easy to be blown, close doors and windows, and stick them with adhesive tape.The "meter" figure.

Don’t stay near buildings, billboards and telephone poles, and beware of falling objects.

Pay attention to the safety of food and water after the typhoon.

The film includes 17 concerts. Martha joked about making a sequel.

　　"Pursuing Dreams in Mayday 3DNA" is the first time for these five people to make a movie. There are many clips of their concerts in the film, and the golden songs are endless. A Xin, the lead singer, revealed: "It feels very fresh to make a movie like this. There are almost 17 concerts in it." Because it is a 3D movie, the camera used in shooting is very advanced, and A Xin also "threatened" that the visual effect of this movie would not be lost to.

　　The three stories in the film were not filmed in Beijing. When asked why, bassist Martha immediately joked, "Maybe the director thinks Beijing is too cold, or maybe the sequel will be filmed in Beijing." Just after that, Martha "repented" again. "Everyone knows that I am the most irresponsible person in May."

The number of finless porpoises living in Nanjing section of the Yangtze River is increasing, and the biodiversity of their homes is becoming increasingly rich. Yesterday, the Municipal Bureau of Greening and Landscape Architecture released the dynamic investigation of biodiversity in the Yangtze finless porpoise provincial nature reserve (hereinafter referred to as the "reserve") from 2023 to 2024. The reporter learned from the press conference that the number of finless porpoises and birds in the reserve has increased; Precious and endangered species and wetland plants are rich in distribution; The water environment has reached Class II value of fishery water quality and surface water environmental quality standard. The overall ecological environment quality is stable and improving.

New changes: the number of finless porpoises in the reserve has increased from 62 to 65.

The Yangtze finless porpoise is the only existing cetacean in the Yangtze River, which is a national first-class protected wild animal and an important indicator species to test the health of the Yangtze River ecosystem.

Nanjing is the only big city in the whole Yangtze River basin where you can see the wild finless porpoise at close range in the central section of the city. In 2014, Nanjing finless porpoise reserve was formally established, starting from Xinshengzhou in Jiangning District in the west, adjacent to Maanshan City in Anhui Province, and east to Nanjing Yangtze River Bridge, with a planned total area of 80.38 square kilometers, including 51.52 square kilometers in the core area and 28.86 square kilometers in the experimental area.

The dynamic investigation of biodiversity in the nature reserve lasted from the autumn of 2023 to the summer of 2024. According to the investigation and analysis of four quarters, the number of finless porpoises in the finless porpoise nature reserve showed an increasing trend.

Zhang Ruizhong, a first-class researcher of the Municipal Bureau of Greening and Landscape Architecture, said that the number of Yangtze finless porpoises in the reserve is about 65, an increase of 4.84% compared with the 62 in the background resources survey in 2022. The finless porpoise is generally distributed continuously, and its Jizhou-Zimuzhou waters and Qianzhou waters are hot spots. There are also seasonal differences in distribution, especially in the waters of the Yangtze River Bridge from Xinshengzhou to Dashengguan, which are mainly affected by geographical location, hydrological conditions and fish resources. During the investigation period, the mother and child dolphins were also observed for 9 times, which means that the Yangtze finless porpoise population in the reserve has good development potential.

New discovery: rich biological resources, rare bird black stork first appeared.

A finless porpoise needs to be strong in order to breed, and it needs to have enough food in order to be strong. An important reason for the decrease in the number of finless porpoises in the Yangtze River is that the food sources of finless porpoises are reduced due to uncontrolled fishing. With the ten-year ban on fishing in Nanjing, the Yangtze River has not only been able to recuperate, but also provided valuable survival opportunities for rare animals such as finless porpoises.

According to Zhang Ruizhong, this survey found that the protected area is rich in aquatic biological resources and there are many precious and endangered species. A total of 105 species of phytoplankton, 59 species of zooplankton, 56 species of benthos and 47 species of fish were collected and identified. In addition to the Yangtze finless porpoise, which is a national first-class protected wild animal, there are also two national second-class protected aquatic wild animals: Myxocyprinus asiaticus, an endangered species in China’s Red Book, and the aquatic wild animals in Jiangsu Province, such as Anoplophora longirostrata, Anguilla japonica, Diplodocus and tong yu.

There are also many kinds of birds in and around the reserve. A total of 123 species of birds were recorded in the survey, including 4 species of national first-class protected wild animals: except yellow-breasted pomfret, oriental white stork and black-faced spoonbill, black stork appeared in the reserve for the first time; In addition, there are 20 species of national second-class key protected wild animals: Pheasant, White-breasted Jade, Aurora, Lark, Black Kite, Peregrine Falcon, Red-footed Falcon, Swallow, White-tailed Cocktail, Sparrow Eagle, Hongyan, Little Swan, Little White-fronted Goose, Yuanyang, White-fronted Goose and baikal teal.

New achievements: the ecological environment quality of the reserve is steadily improving.

According to Zhang Ruizhong, this dynamic survey found that there are abundant wetland plants in and around the reserve. A total of 367 species of wetland plants were collected and identified, including 5 species of gymnosperms, 5 species of pteridophytes, 267 species of angiosperms and 90 species of angiosperms. It is divided into 4 vegetation types, 9 vegetation types and 49 formations. At the same time, two national first-class protected wild plants, Metasequoia glyptostroboides and Ginkgo biloba, and two national second-class protected wild plants, namely, Metasequoia glyptostroboides, Ginkgo biloba and Cinnamomum camphora, were also discovered, among which Metasequoia glyptostroboides and Cinnamomum camphora were all cultivated artificially.

The survey shows that the water environment quality in the reserve is good. The five main physical and chemical indexes of water body, such as pH value, dissolved oxygen and total phosphorus, have reached Class II value of fishery water quality standard and surface water environmental quality standard. The average comprehensive nutritional status index of the sampled water bodies is 47.03, and the comprehensive nutritional status index of 63% of the water samples is in the range of 30-50.

The dynamic investigation was organized and implemented by the Nanjing Yangtze finless porpoise provincial nature reserve management station, and undertaken by the Freshwater Fisheries Research Center of the Chinese Academy of Fishery Sciences and Nanjing Normal University.

Liu Kai, a researcher at the Freshwater Fisheries Research Center of the Chinese Academy of Fishery Sciences, who is in charge of the dynamic survey, believes that the overall survey results show that the ecological environment quality of the nature reserve is steadily improving, the number of Yangtze finless porpoises is increasing, and the biodiversity is generally stable.

The reporter learned that since its establishment, the nature reserve has intensively launched a number of innovative measures for the protection of finless porpoises, such as the national initiative and the introduction of the "List of Responsibilities for the Protection of Yangtze Finless Porpoises in Nanjing" to establish a long-term coordination mechanism for the protection of finless porpoises; The decision on strengthening the protection of the Yangtze finless porpoise was promulgated and implemented in conjunction with the inter-provincial collaborative legislation of Zhenjiang and Maanshan provinces, which became the first basin-based regional collaborative protection legislation for a single species in China; Gradually build a normalized protection system for patrol and rescue, as well as the first application of the "water-underwater-shoreline" monitoring system in China. At present, combined with the study of finless porpoise’s activity habits and habitat environment, the protected area is still improving the level of intelligent, accurate and scientific protection.

The immune system can also get sick and even be life-threatening.

　　"Wang Lin, a qigong master, died of multiple organ failure due to ANCA-related vasculitis and autoimmune peripheral neuritis." This news brought "immune system diseases" into public view.

　　In the course of millions of years of evolution, human beings have formed a complex defense mechanism against foreign microorganisms and harmful substances. This defense mechanism has a clear division of labor and powerful functions, and can cope with the changes and challenges of the living environment. We call it "immune system".

　　But like other organs of the human body, the immune system will get sick and even be life-threatening. What’s wrong with this?

　　The innate immune system is derived from invertebrates.

　　The normal immune system consists of immune organs, immune cells and immune molecules.

　　Immune organs mainly refer to lymph nodes, spleen and thymus. Among immune cells, there are cells involved in immune response and immune regulation, mainly T lymphocytes and B lymphocytes. Among them, T lymphocytes come from thymus and play an important role in the regulation of immune response, while B lymphocytes are mainly involved in the formation of antibodies, including autoantibodies. Immune molecules are mostly synthesized and secreted by immune cells, which play an important role in the initiation and regulation of immune response and the attack on tissues and organs.

　　Humans have inherited the innate immune system of invertebrates in the process of evolution. This ancient defense system identifies invading external pathogenic microorganisms through germinal cells widely distributed in human immune organs; Through the macrophages of innate immune system, we can identify the virulence factors of main microorganisms, directly kill pathogens and protect human body. This kind of protection is an immune response that is quickly started and mobilized, and it is non-specific. That is to say, innate immunity is reacted and cleared in the same way for any foreign microbial invasion, so it is not the most effective.

　　However, while the innate immune system slows down infection, it will activate the acquired immune system-the acquired immune system. Acquired immunity will react specifically to foreign antigens or pathogens. After the first contact with antigens, the second contact with the same antigen can trigger a faster and stronger immune response, attack foreign antigens and remove them from the body.

　　In short, the normal immune system has three important characteristics: one is a variety of antigen receptor libraries, which can identify almost endless pathogens; The second is immune memory, which can initiate a rapid memory immune response, which is why we can be immune for life after injecting some vaccines; The third is immune tolerance to avoid immune damage to normal self-tissues.

　　Distinguish the Immune Tolerance of "Friend or Foe"

　　The most important function of so-called "immunity" is to identify "self" and "non-self", and it will not produce immune response to its own tissue components, which is called immune tolerance.

　　The human body can achieve immune tolerance through autoantigen isolation, so that its own tissues can not contact with the immune system, and the specific immunity of related T or B cells is "unresponsive". For the "non-ego" of foreign microorganisms or foreign tissues and organs introduced into the body, the immune system will protect the body from the damage of intruders by starting an immune "response" reaction.

　　Therefore, if the function of the immune system is disordered and the normal components of the body are regarded as foreign substances, autoimmune diseases will occur. From the pathogenesis, autoimmune diseases are diseases caused by the breaking of immune tolerance. The immune system cannot correctly identify "self" and "non-self", thus attacking its own tissues and organs.

　　In addition, the dysfunction of T cells with the function of regulating immunity can not stop or inhibit the immune response in time, which will also lead to the occurrence of autoimmune reaction.

　　Autoimmune diseases are related to genes.

　　It is necessary for us to understand the role of genes in autoimmune diseases.

　　In the process of immune response, many auxiliary molecules are needed to produce specific immune response against foreign microbial antigens. Among them, the most important helper molecule is MHC (major histocompatibility complex). T cells can be activated and the subsequent immune response can be initiated only after the foreign microbial antigen and MHC molecules combine to form a complex.

　　MHC is usually called human leukocyte antigen (HLA), and its related gene is located on chromosome 6. HLA antigen complex is regarded as the genetic determinant of immune activation. In other words, HLA mainly determines the characteristics of immune response and the occurrence and development direction of immune response. At present, more and more genetic studies show that HLA determines a person’s susceptibility to many diseases, especially autoimmune diseases. People who carry these susceptibility genes have a much higher risk of autoimmune diseases than the general population.

　　In reality, scientists have found some susceptible genes related to autoimmune diseases. It is certain that human immune response is influenced by genetic factors, and some autoimmune diseases have genetic tendencies.

　　People with genetic susceptibility should beware of "molecular simulation"

　　Generally speaking, autoimmune diseases often occur in genetically susceptible people. Their immune cells have abnormal functions, and they will get sick when they encounter suitable external triggers.

　　These external triggers include microorganisms, such as some bacterial or viral infections, and some harmful substances in the environment, such as smoking. For example, some microbial antigens, such as staphylococcal protein A and staphylococcal enterotoxin, can stimulate T or B cells, making these cells transform into autoreactive T or B cells, leading to autoimmune reactions.

　　In addition, because the components of some microorganisms are similar to the fragments in normal human tissues, the normal immune response to foreign microorganisms will activate autoimmune lymphocytes in the form of "molecular simulation" or cross-reaction, causing autoimmune reactions. The most typical autoimmune disease caused by molecular simulation is rheumatic fever. The anti-Streptococcus M protein antibodies in rheumatic fever cross-react with actin, laminin and antigens of nervous system, and start inflammatory reaction in the heart, causing rheumatic heart disease. If these antibodies enter the brain tissue, they can cause chorea. Studies have shown that in type I diabetes, rheumatoid arthritis and multiple sclerosis, there is a "molecular simulation" effect between this microbial protein and human tissues.

　　In a word, the immune system is a delicate and complex barrier to protect the body from external harm. However, the pathogenesis of autoimmune diseases is very complicated, so far, the exact pathogenesis of a considerable number of diseases has not been fully studied. It should be noted that after the occurrence of autoimmune diseases, patients should seek medical advice in time, diagnose and treat early, so as to avoid irreversible damage to important organs.
