BACKGROUND: Because the orthotopic liver transplantation (OLT) was performed widely in recent 5 years throughout China, the proportion of recipients whose graft function deteriorated to be retransplantation candidates increased gradually. This study was undertaken to analyze clinical experience of orthotopic liver retransplantation (re-OLT) at our center. METHODS: The medical records of 80 patients who had undergone liver retransplantation at our center from January 1999 to July 2005 were analyzed retrospectively, including indications and timing of retransplantation, surgical techniques, and the causes of death. RESULTS: The commonest cause leading to hepatic graft loss and subsequent retransplantation was biliary complications in 36 patients (45%). The patients underwent retransplantation more than 30 days after their primary transplant recovered better than those who underwent retransplantation within 8-30 days after primary transplantation (peri-operative mortality 19.6% versus 70%). Sepsis (12 of 22 patients, 54.5%) and multiple organ failure (4 of 22 patients, 18.2%) were leading causes of re-OLT recipient deaths. CONCLUSIONS: Proper indications and optimal operative time, surgical procedures, perioperative monitoring and appropriate postoperative treatment contribute to the improvement of the survival rate of patients after liver retransplantation.

由于时代的局限性以及地理单元的独特性,以往城市空间结构理论的研究热点多集中于经济较为发达的东部地区或特大型城市,对于欠发达西部地区的中小城市关注不够。基于RS与GIS技术,通过1995年、2000年、2005年、2010年、2015年5期TM遥感影像提取城市建成区数据,利用城市空间扩展强度和速度指数、紧凑度、分形维数及形状指数对三峡库区重庆段20 a间城市空间扩展及形态演变定量分析。得出以下结论及建议:(1)随着时间增长,城市空间扩展强度及速度总体呈上升趋势,紧凑度持续降低,城市建成区面积逐年递增,城市扩展极不稳定;(2)城市空间形态受重大事件影响易发生"突变",随着时间的沉淀,空间形态再发生"整合";(3)1997年重庆直辖以来,前10 a的移民安置工程为城市形态的"突变"提供了良好契机。2007年之后,在经济发展作为城市空间扩展的核心动力支撑下,研究区城市扩展主流模式侧重于沿一到两个方向扩展,形成"一心两辅"的发展态势;(4)在未来城市发展规划中,应坚持可持续发展理念、合理规划用地布局,优化产业结构,加强环境保护,避免"边发展、边污染"的被动局面,同时结合自身交通运输条件的优势,在各个方向上形成依附在中心城镇周围的腹地并作为未来扩展的基础,构建副中心城市,将城市形态有序沿城市发展中心蔓延,形成"一核多翼"的发展态势。

Insulin is widely used in treating diabetes, but still needs to be administered by needle injection. This study investigated a new needle-free approach for insulin delivery. A portable powder needleless injection（PNI） device with an automatic mechanical unit was designed. Its efficiency in delivering insulin was evaluated in alloxan-induced diabetic rabbits. The skin irritation caused by the device was investigated and the results were analyzed in relation to aerodynamic parameters. Inorganic salt-carried insulin powders had hypoglycemic effects, while raw insulin powders were not effective when delivered by PNI, indicating that salt carriers play an important role in the delivery of insulin via PNI. The relative delivery efficiency of phosphate-carried insulin powder using the PNI device was 72.25%. A safety assessment test showed that three key factors（gas pressure, cylinder volume, and nozzle distance） were related to the amount of skin irritation caused by the PNI device. Optimized injection conditions caused minimal skin lesions and are safe to use in practice. The results suggest that PNI has promising prospects as a novel technology for delivering insulin and other biological drugs.

《中华儿科杂志》2009年第8期刊载的“儿童腹泻病诊断治疗原则的专家共识”（以下简称“共识”）。“共识”很好地反映了当今国际上腹泻病研究的新成果，推荐使用新ORS（“低渗”ORS）配方，强调患儿在腹泻发生时及早补锌，为儿科临床工作者以及卫生保健工作者提供了儿童腹泻病诊断治疗的新方案，对更好地开展我国腹泻病的诊断治疗工作有着极其重要的作用。在临床工作中，我们觉得有一些问题值得商榷。
