Objective To evaluate the safety,feasibility of primary closure after laparoscopic common bile duct exploration (LCBDE).Methods We retrospectively analyzed the clinical results of laparoscopic common bile duct exploration for common bile duct stones in 119 cases between July 2009 and August 2012.After all stones were removed,there were 63 cases with primary closure of the common bile duct (group A),and 56 cases with T tube drainage (group B).Results All operations were finished laparoscopically.There was significant difference in terms of operation time,postoperative hospital stay and fluid replacement between the two groups.There was no postoperative extrahepatic duct stenosis and biliary residual stones in the two groups.Conclusions Primary closure of common bile duct after LCBDE for common bile duct stones is safe,efficient and feasible.

Objective To observe the clinical effect of α1-antitrypsin gene therapy in the treatment of diabetes.Methods 81 cases with type 1 diabetes were randomly divided into conventional treatment group,islet stem cell transplantation group and gene therapy group,27 cases in each group.The conventional treatment group received the insulin therapy,the stem cell transplantation group received the islet cell transplantation,and the gene therapy group received stem cell therapy of α1-antitrypsin gene.The clinical effect of these three groups were observed.Results The insulin concentration of the gene therapy group was significantly higher than the islet stem cell transplantation group and the conventional treatment group at five time points(F =1 349.379,1 831.186,1 068.173,416.080,257.810,all P ＜0.05).The glucose concentration of the gene therapy group was significantly lower than the other two groups at six time points (F =1 212.243,586.057,962.495,582.887,650.015,1 181.808,all P ＜ 0.05).The degree of inflammatory cell infiltration in the gene therapy group was significantly lighter than in the islet stem cell transplantation group.Conclusion α1-antitrypsin gene therapy can significantly improve the therapeutic effect of diabetes,which is worthy of clinical application.

The choice of the topic area and specific problem on which to conduct research is the mostimportant step in the research process.This paper focused on the development and execution of a clinical re-habilitation research study. The choice of the topic area. principle of research design. data collection and dataanalvsis of a research study have been discussed.

In this study an acute rejecting model of heterotopic rat heart-lung transplantation was established by using simplified technique of end to side anastomosis of donor ascending aorta with recipient abdominal aorta.The measurements of tumor necrosis factor alpha(TNF-α)in serum of rats by Sandwich-ELISA method were taken on the 3rd,5th,7th days respectively after operation.The results of this study with histological examination showed that TNF-α serum levels were increased during acute rejection episodes.and it might be a useful indicator for diagnosis of allograft rejection.
