Objective To explore the factors for the development of gallstones after gastrectomy. Methods 52 cases of patients with postgastrectumy,were retrospectively analyzed according to their diseases for gastrectomy and operation form. Results Incidence of gallstone in patients of postgastrectomy was higher than in general population. Among which, Billroth Ⅱ type of gastrectomy for carcinoma was the highest (35.5%), then the total gastrectomy (31.5%) and proximate gastrectomy(13.5%). Billroth Ⅰ type operation was 10.3%. Incidence of gallstone in pa-tients of selective vagotomy was lowest (2.5%). Condusion Billroth Ⅱ type of gastrectomy and total gastrectomy were the risk factors of postgastrectomy cholelithiasis. The causes for gallstone formation after Billroth Ⅱ type of gas-trectomy were the restitution of digestive canal and metabolic disorder of bile acid.

Objective To explore the clinical curative effect of the modified Sugiura surgieal operation on the portal hypertension. Methods Look back of sex analysis the Sugiura surgical operation of 30 enforcement im-provement to cure a door the disease sufferer's clinical data of the vein high pressure. Results Measure a free door vein pressure(FPP) respectively in the Sugiura operation: slice before the Pi FPP for (3.06±0.39) kPa, slice after the Pi FPP for (3.07±0.32) kPa, leave to break after the surgical operation FPP for (3.22±0.31) kPa, showed difference(P <0.01) very much with slice before the Pi after slicing Pi,but with leave to break surgieal iperation be-hind do not show difference(P > 0.05). 2 earlier period appear the liver brain disease.27 patients 3 ～ 6 eclipse of the moon tube basic disappearance of the varixes after the surgical operation, die in cirrhosis after a surgical operation bad for 16 months change. There are 25 sufferers with visit for 3 years,2 appear again to bleed up the digest way and the forward didn't discover the liver brain patient's. Conclusion Improve the Sugiura surgical operation cures the dis-ease more ideal valid surgical operation type of a vein high pressure,long-term after can lower surgical iperafion again the issue of blood rate,varix relapse the attack source of vitality rate of rate and liver brain.

Objective:To understand the needs, problems and challenges of medical personnel in the hospital for scientific research, propose tailored management measurements and suggestions for the hospital.Methods:The questionnaire was prepared by " Questionnaire Star" , the convenience sampling method was used, and information was collected by WeChat online chat group. Factor analysis and multi-dimensional preference analysis were adopted to analyze information collected.Results:Four main factors that affect the scientific research of medical personnel were identified. The most significant impact is the lack of information platform, followed by the lack of environmental atmosphere, lack of personal capacity and lack of personal interest. The research needs of medical personnel are divided into two categories: one is the more basic skill needs, which are mainly targeted at female, nurses, undergraduates, 5~10 years′ working experiences, medium-grade professional title, and people with no knowledge and experience in research. The other one is the needs of skill improvement, which are mainly targeted at younger, physicians, early career, lower professional titles, and had certain research knowledge.Conclusions:So far, there is a lot of space for improvement. It is recommended to promote the capacity building by training, strengthen the research team building and construct of research communication platform, at the same time, update the scientific research management system.
