Objective To investigate the causes of intractable abdominalgia after simple choleystectomy and analyse the therapeutic effect of endoscopic sphincterotomy (EST).Methods 84 patients undergoing EST were retrospectively viewed from 1987 to 1998. Results Sixty five out of 84 patients were followed up, in which the clinical signs disappeared completely in 51 cases (78%), and there were 6 cases with relapsing symptom(9%),3 cases with intermittent relapsing symptom (4%). Therapy was ineffective in 5 cases. The intractable abdominalgia is a specific sign of postcholecystectomy syndrome. EST is effective in removing the nervous structure in duodenal papilla submucosa and sphincter muscle layer responsible for abdominal pain, therefore eliminated or relived the pain.Conclusion EST has a significant effect on intractable abdominalgia after simple cholecystectomy in the majority of patients.

A service system was created that the tertiary hospitals as the leader, the secondary hospitals as the core and the basic hospi-tals as the foundation, formed the one-stop three level medical rehabilitation service system. It made the referral process more convenient with the operation of the one-stop service, along with the integrated management, the homogenization treatment and the one-stop three level medical institutions;and also solved the problems of the inadequate of rehabilitation medical institutions, the lackage of rehabilitation profes-sionals and the uneven professional and technical condition, that realized hierarchical rehabilitation and two-way referral to meet the rehabil-itation needs of patients.

Objective To study the experience of laparoscopic repair in gastric and duodenum perforation. Methods 35 patients with gastric and duodenum perforation were performed laparoscopic repair.Results 34 pati- ets with gastric and duodenum perforation were safely operated.1 case with perforation of gastric carcinoma was con- verted to open for radial gastrectomy.The mean time of hospitalization was 7.5 days.There was no intraoperative and postoperative complications.Pathological examination showed 4 patients with perforation of gastric ulcer and one with perforation of gastric carcinoma.Conclusion Laparoseopic repair was one of the safe,quick recovery and little suffering treatment for duodenum perforation.

Object To study the effects of gypenosides on MAO and Na/K ATPase activities in brain tissues of aging mice Methods Models of aging mice were prepared by continuous post orbitol injection of 120 mg/kg D galactose for a month, then the effects of gypenosides on MAO and Na/K ATPase activities in brain tissues were investigated Results It was observed that MAO activity was increased and Na/K ATPase activity was decreased in brain tissues of aging mice models significantly; and these effects were reversible respectively by gypenosides ig of 75 and 150 mg/kg Conclusion The result that gypenosides could invert the changes of MAO and Na/K ATPase activities in brain tissues of aging mice, may provide a further explaination of the anti aging mechanism of gypenosides in molecule enzymology

Purpose:To study the influence of chemotherapy on radiotherapy in locally advanced nasopharyngeal carcinoma. Methods:96 patients with histologically proven nasopharyngeal carcinoma in stages Ⅲ,Ⅳ were divided randomly into two groups. Radiotherapy group (48 cases) only received radiotherapy with DT66—76Gy in nasopharynx and DT50—70Gy in the neck. Chemoradiotherapy group (48 cases) received chemotherapy with cisplatin and 5 fluorouracil before the same radiotherapy as the radiotherapy only group. Results:The 1,3,5 year survival rates were 94.2%,72.9%,65.7% in chemoradiotherapy group and 89.1%,56.8 %,46.8% in radiotherapy group respectively, with significant difference between the two groups ( P

0.05) between the two group. Conclusions:No significant difference, concerning efficacy and toxicity ,is shown between domestic made and imported vinorelbine plus cisplatin combination chemotherapy in treating non small cell lung cancer.

objective: To investigate the effect of recombinant human basic fibroblast growth factor (rhbFGF) on cell proliferation during mandible fracture healing. Methods 8 ?g of rhbFGF in 0.3 ml of H 2O was mixed with 1.6 ml of bovine type 1 collagen and then the mixture was vacuumed to be a membrane. The membrane was implanted around the mandibular fracture following the fracture was made in 25 rabbits. 5 animals were sacrificed 1,2,4,8 and 12 weeks respectively after operation. Proliferating cell nuclear antigen (PCNA) in callus was examined with immunohistochemical staining. Type 1 collagen membrane was used as the control in another 25 rabbits. Results:1 week after operation, PCNA positive cell(%) in callus in rhbFGF treated and control group were 65.2?6.1 and 32.0?5.5 respectively ( P

Objective　To establish the method of noninvasive measuring the new indexes of cardiac functions by echocardiography and illustrate the diagnostic values of the indexes.Methods　By use of simultaneous screen display of echocardiography, phonocardiography and electrocardiography and synchronously monitoring blood pressure (BP) technique, the values of LV end-systolic and end-diastolic long and short- axis dimensions, wall thickness and area sizes,and synchronous BP were measured in the patients with myocardial infarction (MI) of defferent sites and area sizes before and during BP were altered to defferent degrees. The values of maximum elasticity (Emax) and average maximum myocardial elasticity stiffness (maxEav) and ejection blood fraction (EF) were calculated through computer programmed process.Results　The order of values of Emax,maxEav and EF among MI patients of defferent sites was control group>inferior MI group>anterior MI subgroup>multi-wall MI subgroup. Their order among MI patients of defferent area sizes was control group > small area MI subgroup > larger MI subgroup. Emax was associated with the MI parts and 　maxEav was associated better with the MI area sizes.Conclusions　The study has established a noninvasive method of examining cardiac function by use of echocardiography and reflected the special diagnostic values of Emax,maxEav and EF in MI patients of defferent parts and area sizes.
