【摘要】 目的 探讨西罗莫司局部缓释对成形术后血管壁纤溶酶原激活物抑制剂1(PAI1)及组织型纤溶酶原激活剂(tPA)表达的影响。方法 建立大鼠颈动脉损伤模型,Wistar雄性大鼠30只,分为实验组(20只)及对照组(10只)。西罗莫司采取外膜给药,以pluronic F127为药物释放载体,给药浓度分为高浓度组600 μg/100 μl及低浓度组300 μg/100 μl,应用免疫组化检测西罗莫司局部缓释对血管壁PAI1及tPA表达的影响。结果 损伤后15及30 d,西罗莫司高、低浓度实验组均促进新生内膜中PAI1的表达(P < 0.05),对中膜PAI1表达的影响除高浓度15 d组与对照相比无统计学差异(P > 0.05)外,其余各组均高于对照组(P < 0.05)。损伤后15及30 d,西罗莫司实验组新生内膜tPA的表达低于对照组(P < 0.05),而中膜tPA的表达高浓度 15 d及30 d组低于对照组(P < 0.05),低浓度组与对照组相比无统计学差异(P > 0.05)。结论 西罗莫司局部缓释在抑制新生内膜增殖的同时亦造成局部PAI1的高表达及tPA的较低表达,两者表达的失衡可能成为晚期血栓形成的重要原因。
