Department of Gastroenterology, Southwest Hospital, was established in 1950s by Liu Wei, a professor, and it is a clinical department integrating medicine, teaching and research. Digestion laboratory was established in 1958, which is one of the earliest professional laboratories in China. 1978 became the first batch of master's degree authorization points, and 1986 became the doctoral degree authorization discipline. 1988 is the first batch of key disciplines in the Third Military Medical University, and 1995 is the key discipline in Sichuan Province. 1998 approved postdoctoral mobile station. 1998 is the national clinical pharmacology research base, 1999 is the first batch of key disciplines in Chongqing, in 2000, it was the specialized center of digestive diseases of the whole army, in 2000, it was the Chongqing Institute of Digestive Diseases, and in 2005, it became the Institute of Digestive Diseases of the whole army. There are two wards in Chongqing, 1 Digestive Endoscopy Center and 1 Key Laboratory, with 80 beds, with a total area of * * * 2,500 square meters, with an annual outpatient volume of 23,775, and patients treated 1 person-time. In 2006, the endoscopic center of this discipline became the only endoscopic training base in the southwest of the Ministry of Health. The laboratory is equipped with molecular biology room, cell culture room, biochemical room, pathology room, immunohistochemistry room, radioimmunoassay room, gastrointestinal motility room, electrogastrogram room and so on. , cell culture, protein purification, PCR detection, Southen hybridization, Northern hybridization, in situ hybridization, gene transfection, DNA sequencing, radioimmunoassay, gastrointestinal function detection and many other experimental techniques were carried out. This topic focuses on the molecular genetic mechanism of gastric cancer and precancerous lesions, the new targeted therapy of digestive tract tumors, the adaptive molecular mechanism of complications of chronic liver diseases, the protective mechanism of gastrointestinal mucosa and the diagnosis and treatment of early digestive tract tumors under endoscope. Since the "Tenth Five-Year Plan", * * * has undertaken 20 national natural science funds and 5 provincial and ministerial-level (military) projects, with research funding of 4.2 million yuan; Published 457 papers, including 34 papers included in SCI; Editor-in-chief of monograph 10, obtained the practical patent 1 item. Since 1987, * * * has won 20 scientific and technological achievement awards at or above the provincial level, including 1 national scientific and technological progress award and 19 provincial and ministerial level (military) award. Located in the southwest of China, this discipline has trained and transported a large number of high-level talents in gastroenterology for the southwest, and contributed to improving the prevention and treatment level of digestive diseases in this area and changing the situation of high incidence of digestive diseases and lack of medical personnel, especially high-level talents in the southwest. During the Tenth Five-Year Plan period, * * * enrolled 2 postdoctoral students, 67 doctoral students (56 graduates) and 92 master students (74 graduates). Three phases of "Training Course on New Progress of Early Gastric Cancer and Precancerous Lesions", "National Training Course on Digestive Endoscopy" and "National Specialized Training Course on Digestive Diseases" were held, and more than 1 100 people from all over the country participated in the training. It has trained 184 advanced students from 25 provinces, municipalities and autonomous regions in China (32 of them have senior professional titles when they come to the hospital for further study). At present, 50 students have become the leaders of internal medicine in hospitals above the second level. As a digestive disease research institute of the whole army, it adheres to the main idea of serving the army, aiming at improving the textile and scientific research level of the army in war emergency and gastrointestinal functional diseases, and improving the combat effectiveness of our army. Become a high-level digestive disease professional training base and our army digestive disease prevention and treatment center. During the Tenth Five-Year Plan period, our department has sent 35 graduates to hospitals at all levels of the whole army, and they have become the business backbones of all units. Talent structure: the talent echelon of the department is reasonable, forming an outstanding team of scientific and technological cadres with young and middle-aged as the backbone, and the main series of personnel have doctoral degrees or above. During the tenth five-year plan period, 2 doctoral supervisors and 3 master supervisors were added; At present, there are 82 staff members, 5 1 main series personnel, 6 returned overseas students, 3 doctoral supervisors and 3 master supervisors. There are 8 senior titles in the compilation, including 5 senior titles and 3 deputy senior titles, with an average age of 40.5 years; There are 7 people with intermediate titles, with an average age of 29; Junior professional title 13, with an average age of 24 years old. The main series includes 4 postdoctoral staff, 0/2 doctors/kloc, 6 masters and 6 undergraduates. Formed an academic echelon with young and middle-aged experts as the leading factor, optimized structure and strong competitiveness. Professor Xu Caipu: well-known expert in gastroenterology, doctoral supervisor, second-class professor, member of the expert group of the Third Military Medical University, enjoying special government allowance. He has been engaged in clinical work in gastroenterology for 50 years and has rich experience in the diagnosis and treatment of intractable diseases in gastroenterology. He used to diagnose and treat diseases for the heads of the military commission and provinces and cities, and the curative effect was good, which was well received. Seriously study the early diagnosis of chronic gastritis, peptic ulcer and gastric cancer under endoscope. A new viewpoint of canceration of chronic benign gastric ulcer has been published abroad, which has attracted the attention of the international medical community, and nearly 100 foreign experts have written and exchanged letters. Professor Fang Dianchun: Doctoral supervisor, visiting scholar at the University of Queensland in Australia and the University of Pittsburgh in the United States, and a famous expert in gastroenterology in China. Engaged in medical treatment, teaching and scientific research for more than 30 years, with solid basic medical knowledge, professional theory and related knowledge of digestive medicine, master the latest development trends at home and abroad, and have deep attainments in clinical basic research of digestive system diseases.
