| 摘 要： | 目的观察丹参多酚酸盐预处理供肝对受体大鼠肝移植术后胆道损伤的影响,探讨其可能的作用机制。方法根据供体肝脏保存方法,受体大鼠随机分为UW液组、丹参多酚酸盐预处理组(UW液+0.4 mg/ml丹参多酚酸盐)、生理盐水对照组(UW液+等量生理盐水)。大鼠行胆道持续外引流肝动脉化原位肝移植,观察移植术后1、6、24 h胆汁流量及胆汁酸盐分泌量。大鼠行肝动脉化大鼠原位肝移植,移植术后2周检测各组大鼠血清碱性磷酸酶、胆汁酸盐及总胆红素水平,观察胆道并发症发生率;采用实时荧光定量PCR、蛋白印迹法分别检测肝脏移植物内胆汁酸盐输出泵(bile salt export pump,BSEP)基因及蛋白的表达。结果与UW液组及生理盐水对照组相比,丹参多酚酸盐预处理组大鼠术后早期胆汁流量及胆汁酸盐分泌量明显增加(P<0.05);术后2周血清碱性磷酸酶、胆汁酸盐及总胆红素水平明显降低(P<0.05),胆汁淤积等胆道并发症发生率明显降低(P<0.01);肝脏移植物内BSEP mRNA及蛋白表达均升高(P<0.05)。结论UW液内加入丹参多酚酸盐保存供肝可明显减轻受体大鼠肝移植术后胆道损伤,降低术后胆道并发症的发生,可能与其促进移植肝内B...

| Abstract: | Objective To evaluate the effect of pretreating donor liver with salvianolate on biliary injury after orthotopic liver transplantation(OLT) in rats,and to discuss the underlying mechanisms.Methods According to the preservation solutions of the liver grafts,the recipients rats were allocated in three groups: UW solution group,salvianolate group(UW solution + 0.4 mg/ml salvianolate),and saline group(UW solution + saline).In experiment 1,the recipient rats underwent arterialized OLT with biliary extra-drainage... |
