中文摘要：

目的:通过肝动脉桥式转流达到移植肝门静脉、肝动脉同时再灌注,探讨其对再灌注早期脂多糖受体CD14表达及肝损伤的影响。方法:选择健康雄性西安地区杂交犬30只,建立简易犬自体原位肝移植模型,随机分为对照组、肝动脉缺血组(HAI组)和肝动脉桥式转流组(HABB组)。检测CD14蛋白表达,肝组织MDA含量、血清ALT水平,观察肝组织形态学变化。结果:HAI组和HABB组的CD14表达随时间延长而增强,并且与对照组之间存在显著性差异(P<0.01);两组于再灌注后4h达到峰值,HAI组CD14表达(11.94±0.43)明显强于HABB组(5.98±0.22)。肝组织MDA含量,血清ALT水平以及肝组织病理学变化同CD14表达呈现出相同变化趋势。结论:肝动脉桥式转流可以达到门静脉、肝动脉同时再灌注,消除原位肝移植过程中的肝动脉缺血时间,减轻供肝的损伤;脂多糖受体CD14介导的内毒素损伤途径受到抑制可能是其作用机制之一。

英文摘要：

Objective:To study the effect of hepatic artery bridge-bypass(HABB) on CD14 expression and liver injury in early reperfusion in canine auto- transplantation livers. Methods:30 healthy male Xi’an canines were randomly divided into control group, HAI group and HABB group. CD14 protein expression, MDA Contents in hepatic tissues and ALT valuse in serum were detected, and the pathological changes of hepatic tissues were investigated under light microscopy. Results:The level of CD14 protein expression in HABB an...
