摘要 目的:了解他汀类降脂药对低氧诱导因子1α(HIF1α)表达的影响,探讨其除降脂以外的抗心肌缺血作用机制。方法:将大鼠随机分为对照组、辛伐他汀组、心肌缺血组和辛伐他汀+心肌缺血组。给辛伐他汀药4周后心肌缺血组和辛伐他汀+心肌缺血组通过结扎冠状动脉左前降支致大鼠急性心肌缺血。分别用逆转录聚合酶链式反应(RT-PCR)法和Western blotting法及免疫组化法检测各组心肌组织中HIF1αmRNA和蛋白的表达。结果:辛伐他汀和心肌缺血组均能使HIF1α表达明显高于对照组(P<0.01),心肌缺血前辛伐他汀预处理可使HIF1α表达进一步增高(P<0.01)。结论:辛伐他汀可能是通过上调HIF1α表达促进新生血管形成,治疗心肌缺血。
