Background Since January 2002, adult-to-adult living donor liver transplantation （AALDLT） has gained increasing popularity in China in response to the shortage of cadaveric donor livers. This study presents a detailed analysis of the outcomes of AALDLT in a single center. Methods A total of 70 patients underwent AALDLT at our center between January 2002 and January 2007. Among these, 67 patients received a right lobe graft without the middle hepatic vein and 3 patients received dual grafts. Three-dimensional volumetric computed tomography, magnetic resonance imaging with angiography and cholangiography were performed preoperatively. Recipient operation time, intraoperative transfusion requirement, length of intensive care unit stay, length of hospital stay, liver function tests, coagulation tests and surgical outcomes were routinely investigated throughout this study. Results All donors survived the procedure with an overall complication rate of 15.3%. Overall recipient 1-year survival and complication rates were 87.1% and 34.2%, respectively. Among the 70 cases, average graft recipient weight ratio was 0.94% （0.72%-1.43%） and average graft volume/standard liver volume ratio was 46.42% （31.74%-71.68%）. All residual liver volumes exceeded 35%. Liver function and coagulation recovered rapidly within the first 7 days after transplantation. Conclusions AALDLT is a safe procedure for the donors and an effective therapy for patients with end-stage liver disease. Patient selection and timely decision-making for transplantation are essential in achieving good outcomes. With accumulation of experience in surgery and clinical management, timely feedback and proper modification, we foresee better outcomes in the future.

农民的政治参与状况直接影响和制约着当代中国社会政治文明的进程。江西省都昌县黄村农民政治参与案例显明,在经济落后的农村地区,村支部往往取代村委会行使村级事务的决策权和管理权,当选的村干部不为民谋利甚至以权谋私,又缺乏必要而有效的约束,结果造成村支部与村委会、村民与村干部关系紧张,村民政治参与意识冷漠,遇事多采取制度外政治参与方式维护自身权益,导致整个社会管理运行成本的增加。解决问题的途径是,从制度创新、经济发展、文化教育、社团建设、政治宣传、舆论监督等方面入手,通过村民自治实践培养村民的政治参与意识,培育和壮大农村市民社会,为建设社会主义新农村提供政治环境和制度支持。
