摘要 目的探讨乌司他丁(ULI)对兔供体肺血管内皮在缺血和再灌注损伤中的保护作用。方法选取成年新西兰大白兔20只,随机分为对照组(n=10)和ULI组(n=10),建立兔供体肺缺血保存和再灌注模型。对照组灌洗液和保存液为Euro-collins液,ULI组灌洗液和保存液为Euro-collins液+ULI。两组均低温保存6 h后行自体血再灌注,测量两组再灌注后血液中循环内皮细胞(circulating endothelial cells,CEC)、血管假性血友病因子(von Willebrand factor,vWF)和血栓调节蛋白(thrombomodulin,TM)以及血氧分压、肺组织含水量等指标。结果对照组和ULI组再灌注后氧分压均较取肺前有明显下降,对照组下降更明显,各组内前后比较差异有统计学意义(P<0.05)。再灌注后对照组氧分压较ULI组低,肺组织含水量较ULI组高,差异有统计学意义(P<0.05)。对照组CEC、vWF、TM均较ULI组升高,差异有统计学意义(P<0.05)。结论灌注液和保存液中加入ULI对兔供体肺具有一定的保护作用,ULI对血管内皮的保护作用之可能是减轻供体肺缺血和再灌注损伤。
