Gastroesophageal variceal bleeding is one of the major causes of death for patients with portal hypertension.The treatment of portal hypertension has evolved from surgery being the only option to the wide range of options currently available,including endoscopic sclerotherapy of varietals ligation,interventional radiology and surgery.Given the shortage of liver transplantation donors,devascularization would be one of the major treatments for portal hypertension for a considerable time.Based on the clinical experience of the People's Hospital of Peking University,we think that peraesophagogastric devascularization without splenectomy is a better option for the treatment of portal hypertension,with less operation time,less intraoperative blood loss and fewer postoperative complications,and better short-and long-term hemostatic effect.

Liver transplantation is the only curative treatment for cirrhotic portal hypertension, especially for the patients with end-stage liver failure. In the era of liver transplantation, when drugs, endoscopy and interventional treatments fail, surgery (not including liver transplantation) is an irreplaceable treatment option for esophagogastric variceal bleeding, which should be individualized, in order not to increase the risk and difficulty of liver transplantation in the future.

Objective To evaluate the safety and efficacy and explore the clinical application value of the enhancement controlla-ble output channel narrowed ileal bladder suspension surgery and traditional ileal neobladder after total cystectomy.Methods From January 2001 to August 2009,42 patients with bladder cancer received enhancement controllable output channel narrowed ileal blad-der suspension surgery after total cystectomy;and 46 patients received ileal neobladder after total cystectomy.Their clinical data, perioperative situation,postoperative complications and tumor progress were analyzed.Results In regard to the blood loss,postop-erative hospital stay,and postoperative recent or far complications,both surgical methods had no significant statistical difference (P >0.05).The group of Enhanced controllable output channel narrowing ileal bladder suspension surgery was good control of uri-nation after operation(P <0.05).Conclusion Enhancement controllable output channel narrowed ileal bladder suspension surgery has good clinical effect and safety.It is especially suitable for the patients who need control inurine and don′t accepted orthotopic neobladder.

Objective To investigate the application of ~(18)F-fluorodeoxyglucose hybrid PET/CT (~(18)F-FDG hPET/CT) imaging in clinical staging of non-small cell lung cancer (NSCLC). Methods Seventy two consecutive patients with NSCLC undergoing ~(18)F-FDG hPET/CT before radiotherapy were analyzed. The results were compared with previous CT scan and conventional clinical staging. The patients were followed-up for at least 6 months. Results Among the 72 patients, the staging grade was changed in 27 patients due to the result of ~(18)F-FDG hPET/CT in whom with 20 patients having their grade raised and 7 lowered. Radical treatment was changed to palliative treatment in view of a raise of staging grade. Because of distant metastasis was detected by ~(18)F-FDG hPET/CT imaging, 14 patients received palliative treatment. Compared with CT, 47 more lymph nodes and 26 distant metastases were found with ~(18)F-FDG hPET/CT imaging, and the patients in question received radiotherapy and palliative treatment accordingly. Conclusion ~(18)F-FDG hPET/CT imaging, by changing the clinical staging in 37.5% (27/72) NSCLC patients, has impact on treatment strategy and treatment planning of radiotherapy in NSCLC patients. Patients were frequently spared unnecessary treatment, and management was more appropriately targeted.

The mitochondria were isolated at 4 h,24 h and 48 h after treatment respectively while the activity of ATPase and SOD and the content of MDA were measured by biochemical technique.Results Activity of ATPase( P

Objective To study clinicopathological characteristics of hereditary nonpolyposis colorectal carcinoma(HNPCC)-associated endometrial carcinoma(EC).Methods Totally 421 EC patients admitted to General Hospital of Tianjin Medical University from 1981 to 2006 were divided into three groups:group A:sporadic EC;group B:familial aggregation of EC;group C:HNPCC-associated EC.Results HNPCC-associated EC accounted for 6.4%(27/421).Mean age at time of diagnosis was 49.7years in group C,earlier than 56.3 years in group A(P=0.004)and 55.2 years in group B(P=0.035).There were 33.3%(9/27)patients with multiple primary carcinomas in group C.It was higher than 14.3%(9/63)in group B and 5.1%(17/331)in group A respectively(P=0.038,P＜0.01).There was no difference among the three groups in histological type or menopausal status(P＞0.05).The numbers of patients with low grade EC in group C(70.4%,19/27)and group B(61.3%,38/62)were more than that in Group A(P=0.013,P=0.023).Prognosis for group C was better than that in group A(P=0.021),and 5-and 10-year survival rate in groups A,B and C was 80%,70%;88%,85%;and 96%,96%respectively.Conclusions Mean age at time of diagnosis is earlier in HNPCC-associated EC than that in sporadic EC;patients with HNPCC-associated EC are more frequently complicated with multiple primary carcinomas and of low grade;prognosis is better.

Objective To explore the effect of cell apoptosis and oxidative stress on stressive liv-er injury after traumatic brain injury (TBI) in rats. Methods The model of TBI was duplicated by u-sing modified Allen's mehtods. Forty male Wistar rats were randomly divided into control group and groups at 6,12,24,48 hours after TBI. The serum levels of ALT and AST as well as the levels of superox-ide dismutase (SOD) and malandialdehyde in liver tissue were measured. The index of hepatocyte apopto-sis was detected through flow cytometer. Pathological changes of liver tissues were observed under light and electron microscopes. Results After TBI, the serum levels of ALT and AST were significantly in-creased, while malondialdehyde was increased and SOD decreased in liver tissues. The electron micro-scope showed that the index of hepatocyte apoptosis reached a peak at 6 hours after TBi. Aggressive inju-ries of the liver tissues were observed after TBI, showed by pathological observations. Conclusion Cell apoptosis and oxidative stress may be involved in the pathogenesis of stressive liver injury after TBI.
