BACKGROUND: Cardiac arrest ( CA) during orthotopic liver transplantation (OLT) is rare but it threatens the lives of patients. The cause of perioperitive CA is not fully understood. We reported the occurrence of CA in 5 patients after unclamping of the vena cava and investigated the relationship between CA and associated variables. METHODS: Five patients with CA after graft reperfusion during OLT in our unit from November 1996 to September 2003 were retrospectively reviewed. Analyzed data included donor and recipient demographic data, and recipient operative and postoperative events. RESULTS: Five (2.1%) of 240 patients undergoing OLT experienced CA 5 minutes after graft reperfusion. Two patients died of resuscitation failure. Hyperkalemia and metabolic acidosis after revascularization were observed in some patients. The five patients had hypothermia and hypocalce-mia, and one had pulmonary embolism. CONCLUSIONS: CA is one of the syndromes after reperfusion. Many factors such as hyperkalemia, acidosis or pulmonary embolism combined with hypothermia and hy-pocalcemia during the operation seem to contribute to the occurrence of CA.

Bio-inspired Iron Porphyrins as Electrocatalysts for the Oxygen Reduction Reaction in Fuel Cells

中国化学会第五届卟啉与酞菁学术研讨会

The oxygen reduction reaction(ORR),one of the most important reactions in life processes as well,has been regarded as a major bottleneck that limits fuel cell performance due to the sluggish cathodic reaction kinetics and diverse reaction pathways. Non-precious-metal catalysts for ORR have long been intensively investigated since the discovery of the capacity of metal complexes with macrocyclic N4 ligands to reduce oxygen electrochemically. However,Non-precious-metal catalysts developed so far usually suffer from substandard performance in fuel cell acidic *** to improve the electrocatalytic activity and mitigate the performance loss with structure-defined catalysts for ORR remains a great *** on our biomimetic mechanistic studies on the binding/activating of O by metalloenzymes such as heme-containing enzymes, we have developed a method of preparing bio-inspired ORR electrocatalysts without traditional pyrolysis treatment,where electrocatalysts of iron porphyrins and copper complexes were covalently grafted onto the surface of carbon nanotubes and other carbon-based supports. This offered the feasibility to tune the catalytic activity via variation of the catalyst structure with defined reaction active *** this talk,I will present our efforts to boost the catalysts ORR performance via rational catalyst design from a bio-inspired approach,and demonstrate their application to low temperature fuel cells.

中国正着手建立覆盖城乡居民的社会保障体系。从国外的经验来看,虽然各国建立这一体系的社会背景不同,但都是在满足一定的人均GDP、工业化与城镇化水平等基本条件下完成的。基于国际比较的经验,对中国建立覆盖城乡社会保障体系的条件进行了比较分析。虽然中国现阶段已初步具备了建立这一体系的基本条件,但条件并不充分。今后应该依据具体国情和条件分阶段逐步推进这一体系的建设。

目的:探讨大鼠胆道梗阻再通术后肾脏水通道蛋白3(AQP3)的变化及其意义.方法:50只大鼠,任选10只为对照组,其余为实验组,实验组先建梗阻性黄疸(obstructive jaundice,OJ)模型,7 d后解除梗阻;按取材时间不同随机分为5组:OJ0h、OJ24h、OJ72 h、OJ1wk和NC.测定血生化指标.Western blot法检测肾脏AQP3水平.结果:随梗阻解除时间延长血清总胆红素(TBIL)和谷丙转氨酶(ALT)逐渐下降(TBIL:93.26±1.32 vs 63.31±1.85,30.78±1.40,5.04±0.24,P0.05),AQP3表达降低;OJ24h BUN、Cr下降,AQP3表达进一步降低.OJ 72 h与OJ 24 h相比BUN、Cr无明显变化,AQP3表达增强,但仍弱于NC(P<0.05);到第7天,BUN、Cr和AQP3均与NC无明显差别.结论:大鼠胆道梗阻解除后短期内因肾功能受损加重,AQP3表达下降后随肾功好转表达增强,其灵敏性和特异度均高于BUN和Cr.
