Stephan Yip,19151010/8, was born in a teacher's family in Hefei, Anhui. Since he was a child, he witnessed the imperialist powers' aggression against China. Warlords fought each other for years, causing frequent epidemics, which made the people of China live in dire straits. In middle school, Ye Tianxing made the wish of "being a good doctor if you don't want to be one", and thought that "strengthening the country first strengthens the body, saving the country first strengthens the people". He is eager to study medicine when he grows up and prevent and treat diseases for the public. He also often goes to a familiar hospital nearby to help with housework. 193 1 When he graduated from middle school, Anhui was in famine and his family was in decline. He became the cousin of the hospital director. Seeing that Ye Tianxing Middle School was diligent and determined to study medicine, he sponsored him to enter Shanghai Southeast Medical College. He studied hard and stayed in school for six winter and summer vacations to study foreign languages and other courses. He is particularly interested in pathology and microbiology, and often takes time out to study experimental techniques in the laboratories of these two courses, which is highly valued by his teachers, Professor Yang Shuzu and Professor Zhang Xiaozong. 1937 After graduation, Ye Tianxing was recommended by Professor Yang Shuzu to study in the Department of Bacteriology, Shanghai Institute of Natural Science, which was founded by Japanese in boxer indemnity, China. Soon after the July 7th Incident broke out, he angrily left the institute and went to Xi with Zhang Xiao's religious prize at the end of 1937. He was once employed as an academic researcher in the Biological Products Division of Shaanxi Provincial Epidemic Prevention Department, and concurrently served as a microbiology and Japanese teacher in Northwest Pharmaceutical College.

1938 Spring, zoonotic (rinderpest) epidemic occurred in northern Shaanxi. Ye Tianxing volunteered to take part in the prevention and control work, so he took vaccines, immune serum and medicines, and arrived in Yan 'an in April with Dr. Bethune who passed through Xi and the first batch of foreign experts who came to China for international epidemic prevention. Lectures on epidemic prevention classes organized by the civil affairs department of the Shaanxi-Gansu-Ningxia Border Region Government and the Ministry of Health behind the 18th Army. Subsequently, Ye Tianxing led epidemic prevention personnel to carry medical equipment to villages in more than a dozen counties in the border region, and went door-to-door to vaccinate soldiers, civilians and farm cattle and inject immune serum. I traveled more than 2,000 kilometers on foot in four months, and completed the task at the end of August, which was well received by the soldiers and civilians in the border area.

In the border area, Ye Tianxing witnessed the incorruptible political style of democratic governments at all levels, the rising anti-Japanese sentiment of the military and civilians, equality for all, social peace, the extinction of opium, prostitutes, gambling and bandits, and a thriving scene, which was far from the situation of corruption, declining social atmosphere and people's poverty in the Kuomintang-ruled areas. This made him deeply feel that "the hope of saving the country lies in China". After returning to Xi 'an, he often talked with friends and students about what he saw and heard in the border region and his feelings. At the end of 1939, the Kuomintang die-hards set off the first anti-communist climax. Ye Tianxing was accused by a few people of being "pro-Communist" and "propaganda for communist party" and was threatened by intimidation. 1In April, 940, he was forced to leave his wife and daughter and fled from Xi 'an to Guiyang, where he took part in the work of the China Red Cross Rescue Corps and the Central Health Laboratory led by Professor Lin Kesheng, engaged in teaching, scientific research and vaccine serum manufacturing.

194 1,1/In June, Stephan Yip participated in the investigation of bacterial weapons infected with Yersinia pestis, such as fleas, dropped by Japanese invaders in Changde, Hunan. Under the threat of germ warfare by the Japanese invaders, the China Red Cross Rescue Corps Department and the Health Department of Chongqing National Government recommended Ye Tianxing as a visiting scholar of Rockefeller Foundation in the United States, and went to British India to study and defend against plague and cholera in April 1942. Under the guidance of Sir Sokai, director of the Khavkin Institute in Mumbai, and Sir Taylor, president of the Central Research Institute of the Indian Ministry of Medicine in Delhi, he studied the prevention and treatment of plague and cholera and developed immune preparations.

1942 10 Stephan Yip's return from India coincided with the frantic throwing of cholera bacterial weapons by Japanese invaders in various parts of China, resulting in cholera epidemics in Hunan, Guizhou, Sichuan, Yunnan, Guangdong and Guangxi. He immediately went to Guiyang to participate in the prevention and control, isolated and identified the pathogenic bacteria, found out the serotyping of the prevalent Vibrio cholerae, revealed that it was released by the Japanese army, and selected strains to prepare cholera vaccine. 1942 to 1945, employed as a bacteriology teacher in Guiyang wartime health personnel joint training institute, working in the vaccine serum laboratory affiliated to the institute donated by Hong, an American Chinese.

1946 At the beginning of this year, pneumonic plague broke out suddenly in Shenyang, China. Lin Kesheng assigned Stephan Yip and others to fly to Shenyang with medical equipment to prevent and control the epidemic together with the personnel of the United Nations Relief and Rehabilitation Agency, and the epidemic situation was quickly controlled. In the same year, Ye Tianxing went to study in the United States at public expense. He studied at American Military Medical College, American Institute of Military Medicine and Cornell University in new york, and studied virology, immunology and microbiology under the guidance of Professor Smale. Because he studies hard and takes the laboratory as his home, he is very appreciated by the school. At the end of 1947, with the determination to serve the motherland and relieve the sufferings of the people, he declined the advice of the United States and resolutely returned to China to become a professor in the Department of Bacterial Serology of the Health Experimental College of Shanghai National Defense Medical College, working with Professor Li Zhenpi. At the same time, he is also a professor at Tongji University Medical College in Shanghai, the president of its affiliated Advanced Medical Laboratory College, and a professor of microbiology at Southeast Medical College. At that time, the People's Liberation War led by China was victorious, and the collapse of the Kuomintang government was imminent. National Defense Medical College1moved to Taiwan Province Province at the end of 948. Judging from the experience of the Shensi-Gansu-Ningxia Border Region, Ye Tianxing firmly believes that "only * * * can save China". On the pretext of refusing to go to Taiwan with the school, he transferred to work in the affiliated hospital of Shanghai, secretly contacted colleagues who did not want to go to Taiwan Province Province, and secretly transferred a large number of teaching and research instruments, medicines and equipment for making vaccine serum donated by the Japanese army to Shanghai Liberation Hospital.

1On May 27th, 949, after the liberation of Shanghai, Ye Tianxing met with Cui Yitian, Minister of Health of East China Military Region of China People's Liberation Army, and Li Zhenxiang, Minister of Health of the Third Field Army, and handed over all the equipment and medicines to China People's Liberation Army. Later, he resigned from his original post and devoted himself to the preparation of the People's Medical College of East China Military Region (the predecessor of the Second Military Medical University). He was hired as a professor of the Health Laboratory and the head of the Department of Bacteriology. During this period, he actively made vaccine serum for the soldiers and civilians in Shanghai after liberation. For this, he was praised and awarded the third class merit. During the War to Resist US Aggression and Aid Korea, he compiled the Inspection Manual of Defensive Bacteriological Weapons and participated in the investigation. 1950- 1954, Professor of Microbiology, Department of Biology, Fudan University, Shanghai, teaching microbiology for the first time.

1952 The People's Medical College of East China Military Region was changed to the Second Military Medical University of China People's Liberation Army, and Ye Tianxing was appointed as the head of the Department of Microbiology, and was later hired as the first-class professor of immunology. Since then, I have lived a stable life and devoted myself to teaching and scientific research.

/kloc-During the Cultural Revolution in 0/0, Ye Tianxing was persecuted to death. After the downfall of the Gang of Four, he was recalled to Beijing by the General Logistics Department of the China People's Liberation Army for rehabilitation. February 1985 Gloriously joined China.

After Stephan Yip resumed his work, he worked day and night to regain the lost 10 year. In addition to teaching in various classes of military medical university, he also instructed graduate students, participated in special scientific research, compiled immunology textbooks, presided over the work of Shanghai Immunology Society, and taught the basic theory and latest progress of immunology to immunology classes held in the whole city, the whole army and the whole country. From 1979 to 1990, a total of 12 volumes of medical microbiology and immunology were edited, and 33 academic papers were published independently or jointly with others, plus more than 70 previously published papers.

Ye Tianxing has served as the first, second and third director of chinese society for microbiology, the third director and consultant of Shanghai Immunology Society, honorary director of Microcirculation Committee of China Research Association of Integrated Traditional Chinese and Western Medicine, and honorary director of China Immunology Society.
