摘要
目的 研究辛伐他汀对动脉粥样硬化兔髂动脉基质金属蛋白酶组织抑制物 1(TIMP 1)表达的影响。方法  18只家兔分为正常对照组 (正常饮食 ,5只 )、基础对照组 (球囊和高脂饮食 ,7只 )和辛伐他汀治疗组 (球囊、高脂饮食和辛伐他汀 ,6只 )。球囊损伤后 4周处死 ,取一侧病变髂动脉做病理切片 ,取另一侧病变髂动脉抽提总RNA和总蛋白 ,分别应用半定量逆转录多聚酶链式反应 (RT PCR)和Western蛋白印迹法 (Westernblot)测定TIMP 1mRNA和蛋白质的表达。结果 辛伐他汀可以显著降低家兔血浆总胆固醇 ,抑制动脉粥样硬化的形成 ;增加动脉粥样硬化兔髂动脉组织TIMP 1的表达 ,正常对照组、基础对照组、辛伐他汀治疗组动脉壁TIMP 1mRNA的相对值分别为 1 5 7± 0 11,2 72± 0 10 ,3 33± 0 2 8,相互间有统计学差异 (P <0 0 5 ) ;正常对照组、基础对照组、辛伐他汀治疗组Westernblot检测结果分别为 2 72± 1 16 ,7 5 1± 1 4 4 ,16 90± 1 4 5 ,相互间有显著性差异 (P <0 0 0 0 1) ;免疫组化观察结果也提示TIMP 1的表达增加。结论 辛伐他汀可以显著增加动脉粥样硬化兔血管组织TIMP 1的表达 ,抑制动脉粥样硬化的形成。
