This study was aimed to carry out pharmacological research on the hemostatic activity and mechanism of Yi medicine Ma-Bu (Paris polyphylla Smith var stenophylla Franch.). One kind of C27 steroidal saponin from P. polyphylla Smith var stenophylla Franch. was isolated and identified as Paris saponin H (PSH). The effect of PSH on the index of bleeding time (BT), prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB) of mice were measured. The results showed that PSH have significant hemostatic activity by shortening BT. The effect of PSH on shortening PT and APTT of mouse was not significant. However, the FIB was enhanced significantly after treatment with PSH. It was concluded that PSH had no significant promoting effect on the extrinsic coagulation pathway (ECP) or the intrinsic coagulation pathway (ICP). The enhancement of FIB may be a pathway for the effect of hemostatic activity by PSH.

BACKGROUND:Research on liver transplantation has not just focused on survival rate and survival time, and the quality of life has become a new field of study. However, it is stil a blank about the quality of life of liver transplant recipients in Xinjiang. OBJECTIVE:To investigate the quality of life of liver transplant recipients in Xinjiang and to explore the main risk factors for the quality of life in patients. METHODS: A Chinese version of the SF-36 health survey was used to retrospectively evaluate the quality of life of liver transplant recipients in Xinjiang. RESULTS AND CONCLUSION:The scores of al eight dimensions in the patients with liver transplantation ranged from 60.6±18.7 to 93.9±22.1. Primary diseases, operation method, marital status, level of education, occupation, gender and age could influence the quality of life of the liver transplant recipients, but nation, income and the way of medical insurance had no significant effect on the quality of life. These findings indicate that there is no obvious difference in the quality of life between liver transplant recipients and normal population, and the scores in six dimensions are higher in the liver transplant recipients than normal population, which is further confirmed that liver transplantation is an effective way for treatment of advanced liver disease.

Objective To describe a new surgical approach to treatment of scapular neck and body fractures and evaluate the clinical outcomes. Methods From December 2002 to October 2004, 13 cases of the scapular neck and body fractures including 9 males and 4 females with age range of 22-48 years (mean 31 years) were admitted into our hospital. There were seven cases with neck fractures, two with associated clavicle fractures, six with mere body fractures, seven with associated subluxation of humeral head and three with associated rib fractures. Internal fixation and open reduction reconstruction using titanium plate and screws were for treatment of scapular neck and body fractures in all 13 cases by making straight incision along lateral border of the scapula. Results The operation lasted for 40-80 minutes, with intraoperative blood loss for 30-80 ml. The follow up for 4-24 months showed average fracture healing time for 6-8 weeks and satisfactory results in 10 cases. Conclusion The surgical approach with straight incision along the lateral border of the scapula can attain perfect reduction and internal fixation of scapular neck and body fractures as well as satisfactory functional recovery with minor (trauma.)

Objective To evaluate the applicability of the simplified equation of MDRD to predict glomerular filtration rate(GFR)from serum creatinine in Chinese patients with chronic kidney disease(CKD),and refit the MDRD equation parameter estimates with Chinese patients data.Methods A total of 760 hospitalized CKD patients were investigated from 2002 to 2005.Patients'sex,age,height and body weight were recorded;plasma creatinine and ~ 99m Tc-GFR(standardized by body surface area)were measured in all patients;GFR was estimated with simplified equation of MDRD and Cockcroft-Gault;the accurancy of estimated GFR with MDRD and CG were compared with~ 99m Tc-GFR in different stage of CKD.Totally 670 patients were randomly selected as the training sample,the remaining 90 patients constituted the validation sample.We used stepwise multiple regression to refit the equation of MDRD and the regression models were developed by using the training sample.The refitting equation was then tested and compared with the other equation in the validation sample.Results (1)Both the MDRD and CG-GFR prediction equations seemd to systematically underestimate GFR,but the accurancy of MDRD equation was better than CG-GFR in stage Ⅰ~Ⅲ of CKD.(2)The bias of estimated GFR(MDRD or CG-GFR equation)with ~ 99m Tc-GFR was lower in stage Ⅰ~Ⅲ than in stage Ⅳ~Ⅴ of CKD.(3)Refitting of the MDRD equation parameter estimates to Chinese patients data set resulted in the following prediction equations:GFR=234.96?(Scr)~ -0.926 ?(Age)~ -0.280 ?0.828(Female).(4)Comparing with~ 99m Tc-GFR,the bias of estimated GFR calculated by the refitting MDRD equation was lower than that of estimated with MDRD or CG especially in the stage Ⅳ~Ⅴ of CKD in Chinese patients.Conclusion the simplified equation of MDRD can estimate GRF accurately,but the equation must be refitted in Chinese patients.

Objective Preparation of a stable and reliable atrioventricular blockage ( AVB) animal model is of great im-portance to anti-arrhythmic drugs and biological engineering research .The aim of the article was to establish a rat model of AVB in-duced by chemical ablation, providing an effective animal model for the development of new drugs . Methods 60 adult SD rats were randomly divided into 4 groups(n=15): normal saline (NS) group, Verapmil (Ver) group, chemical ablation group 1 and chemical ablation group 2.0.9%NaCl (5 mg/kg) was injected into caudal vein of each rat in NS group .Verapmil (5 mg/kg) was injected into the caudal vein in Ver group.Anhydrous ethanol(50μL)was injected into atrioventricular groove area in chemical abla-tion group 1.Anhydrous ethanol(50μL) was injected into atrioventricular node area in chemical ablation group 2.The electrocardio-grams of the rats were examined by electrophysiological recorder.HE staining and Connexin 43 (CX43) immunohistochemical tech-nique were applied to atrioventricular junctions of the rats . Results A rat model of AVB was successfully established .Compared with NS group([45 ±2.24]per field of view), there was a significant decrease in the CX43 expressions of chemical ablation group 1 and group 2 ([15.20 ±2.23]per field of view, [22.10 ±4.70]per field of view)(P<0.05).Concerning NS group and Ver group, myocyte tissues of the atrioventricular nodal region were detected to remain in order without obvious changes and the expres-sion of CX43 immunoreactive protein was obvious under light microscope.As to chemical ablation group 1 and group 2, myocyte tissues were in degenerative necrosis and the expression of CX43 im-munoreactive protein was in lighter staining.Compared with Ver group, the incidence rate(73.3%, 60.6%) and the mortality rate (33.3%, 26.7%)of third-degree AVB decreased remarkably(P<0.05). Conclusion Chemical ablation can be induced to estab-lish a stable and reliable rat model of AVB , providing an effective
animal model for the research and development of new anti-arrhythmic drugs.

Objective To evaluate the curative efficacy of endoscopic retrograde cholangiopancreatography (ERCP) on bile leaks after orthotopic liver transplantation (OLT). Methods Data of 12 cases, hospitalized in our hospital from March 2013 to February 2016, with bile leaks after OLT confirmed by magnetic resonance imaging of the pancreas (MRCP) or ERCP were retrospectively analyzed . The curative efficacy of ERCP was evaluated including clinical symptoms of bile leaks and complications, occurrence time and location, diagnosis and treatment process and efficacy. Results In this study, 12 cases were male patients, with the average age of 49.75 ± 8.55 (age from 35 to 62 years old). Among them 11 cases were successfully treated by endoscopic nasobiliary drainage (ENBD), and the success rate of endoscopical therapy was 91.7%, the curative rate of bile leaks was 91.7%(11/12). No ERCP related serious complications and death were found in patients. Nine cases combined with biliary strictures and/or biliary duct stone/bile plug were performed endoscopic sphinctrotomy (EST) during the first time of ERCP, and accepted further ERCP treatment after 2 weeks when the bile leaks were healed. All patients with ENBD were carried out well except one case. Conclusion ERCP is a safe and effective minimally invasive treatment method for different types of bile leaks after OLT.
