Objective To evaluate the therapeutic effect of combined splenorenal shunt and portaazygous devascularization on bleeding esophageal varices.Methods We summarized 120 cases suffering from esophageal variceal bleeding treated by splenorenal shunt plus portaazygods devascularization,from April,1978 to April,1997.Results The operative mortality was 4.2%,no short-term postoperative bleeding,and long-term postoperative bleeding rate was 9.5%,postoperative hepatic encephalopathy rate was 4.8%.Five,ten and fifteen years survival rate were 83.6%,64.5% and 54.5% respectively. The portal hemodynamics was observed by means of Doppler flowmeter,DSA,and intraoperative portal pressure measurement in some of the patients.Conclusion The result showed that combined shunt and portaazygous devacularization not only preserve the advantage of devacularization but also decrease the portal pressure and blood volume,alleviating portal hyperhemodynamics while preserve hepatopetal blood flow to some extent.

Objective To investigate the causes,diagnosis and treatment of postoperative acute cholecystitis. Methods Clinical data of 9 cases with postoperaive acute cholecystitis were analyzed retrospectively. Results7 cases was confirmed by ultrasonography, 1 case was confirmed by CT, and 1 case died of gallbladder perforation, no operative mortality in emergency cholecystectomy. Conclusion The prevalent etiology is biliary stasis. Early diagnosis and treatment is the key point to decrease the death rate.

Objective To investigate the diagnosis and treatment of cystic adenoid tumor of the pancreas. Methods Retrospective analysis was made on the clinical data of 11 cases of pancreatic cystic neoplasms confirmed by operation and pathology at our hospital from 1978 to 1998. Results Cystic adenoid tumor of the pancreas is more likely to occur in young females with middle age, clinical presentations were as follows: a long-term persistent mass and distending pain in the epigastrium. Utrasounography, CT and ERCP could contribute to the diagnosis. Of the 11 cases, pancreaticoduodenectomy was performed in 2, distal pancreatectomy and splenectomy in 6, local excision of the mass in 2, and loop type cystojejunostomy in 1. The rete of resection was 90.9%. Of them, 1 case died of abdominal abscess and septicemia postoperatively. All the 10 cases who survived postoperatively were followed up. Among the 10 cases, 1 case of pancreatic cystoadenoma died of cardiac infarction 3 months after operation, and 1 case of cystoadenocarcinoma died of metastasis 51 months after tumor excision. The other 8 cases still alived well now. Conclusions Cystic tumor of the pancreas should be suspected when young or middle aged female patients have a long term big mass in epigastrium or left upper quadrant. Ultrasonography and CT scan are helpful in the diagnosis of the tumor including cystoademoma and cystoadenocarcinoma, Although the volume of the tumors may be very big, they often have a intact capsure,so easy to excise. The excision of the total tumor and some arounding pancreatic tissue is the first choice of the treatment for cystic tumor of the pancreas, and the curative effectiveness is satisfctory.

Objective To study the mechanism of 5 fluorouracil(5 FU) in the treatment of severe acute pancreatitis(SAP). Methods SD rats were randomly divided into three groups:acute pancreatitis group (AP group,n=12), 5 FU treatment group( 5 FU group,n=10),and control group (n=10). In 5 FU group,5 FU(1mg/100g) were injected immediately after AP was induced.12h after the AP was induced, blood samples were taken to determine nitric oxide(NO) and interleukin 6(IL 6). Results Compared with AP group,in 5 FU group, the survival rate increased,mean survival time prolonged,ascites volume decreased significantly,and the inflammatory mediators subsided. Conclusions NO and IL 6 may play an important role in the pathogenises of acute pancreatitis. The treatment effect of 5 FU for AP may through inhibit the inflammatory mediators.

Objective: To research the anti-inflammatory and anti-allergic effects of Qifangbimin particle.Methods: The anti-inflammatory effects were observed by the methods of xylene-induced ear-swelling in mice and cotton-ball induced granuloma in rats.The anti-allergic effects were evaluated by the method of passive skin allergy model in rats and ear-heterogeneous passive skin allergy model in mice.Results: In the treatment groups with Qifangbimin particle, the swelling degree of ear edema induced by dimethylbenzene in mice was significantly suppressed when compared with that in the control groups (P<0.01 or 0.05) , however, the particle had no significantly inhibitory effect on granulation tissue hyperplasia induced by cotton-ball in rats.The Qifangbimin particle groups obviously decreased the absorbance value of locus coeruleus on rats' back (P<0.01 or 0.05), and Qifangbimin particle at high dose significantly reduced the absorbance value of locus coeruleus of auricle in mice (P<0.01 or 0.05).Conclusion: Qifangbimin particle has significant anti-inflammatory and anti-allergic effects.

Pulmonary ventilation function of 22 patients with idiopathic scoliosis was assessed. The results showed that there were significantly lower in Vital Capacity, Vita! Capacity % in predicted, Inspiratory Capacity, Forced Vital Capacity, Forced Expiratory Volume in Is, Maximal Voluntary Ventilation, and Maximal Voluntary Ventilation % in predicted of patients than those of age and sex matched normal controls. And there was no any statistical difference of Tidal Volume, Forced Expiratory Volume in Is % in predicted, Maximal Middle Flow, and Maximal Middle Flow % in predicted between two groups. Furthermore, the reduction of Vital Capacity % in patients with idiopathic scoliosis was correlated with the Cobb Angle, Wedge Index and rotation degree of the top vertebral body and not with the scoliosis direction and the patients' age.

Objective To assess the efficacy of one-stage posterior median incision via costotransverse joint in treating thoracic spinal tuberculosis.Methods Thirty three patients with tuberculosis of thoracic spine undergoing one-stage posterior thoracic spine debridement,bone grafting fusion and posterior instrumentation from July 2011 to October 2013 were included in the study.There were 18 males and 15 females.The age was from 17 to 39 years old with an average of 29.5.The course was from 5 to 11 months with an average of 7.3.The Cobb angle was from 19° to 42° with an average of 29.8°.There were 5 in upper thoracic spine,17 in middle thoracic spine and 11 in lower thoracic spine.6 were in Frankel scale grade C,11 were in grade D and 16 were in grade E before surgery.Postoperative kyphosis correction,recovery of neurological function and bone fusion were observed.Results All the surgeries were completed successfully.The operation time was from 120 to 230 min with an average of 183.The blood loss during operation was from 480 to 700 ml with an average of 530.All 33 patients were followed-up for 12-36 months with an average of 22.7 months.The Cobb angle was from 8° to 15° with an average of 10.2°,the correction rate was 77％.The Frankel scale of 11 patients recovered from D to E,2 recovered from C to D and 4 recovered from C to E.The postoperative kyphosis correction and Frankel scale were significantly improved,all patients had a 100％ bone fusion rate and there were no internal fixation loosened or shift of graft bone at the last follow-up.ESR and CRP were returned to the normal range and the tuberculosis symptoms disappeared.Conclusions One-stage posterior median incision via costotransverse joint can complete surgery by the same position and the same incision in treating thoracic spinal tuberculosis with safety and good clinical efficacy.
