摘要 目的观察罗格列酮(Ros)灌胃对兔急性心肌梗死(AMI)后心室重构的影响,并探讨其可能机制。方法将32只日本大耳白兔随机分为假手术(Sham)组、AMI模型组(AMI组)、Ros组、卡托普利(Cap)组,各8只。后3个组采用冠状动脉结扎法建立兔AMI模型。Ros组、Cap组分别予Ros 3 mg/(kg.d)和Cap 5 mg/(kg.d)灌胃,Sham组和AMI组予等量蒸馏水灌胃。4周后测量各组左室收缩末内经(LVESD)、左室舒张末内径(LVEDD)、左室射血分数(LVEF)、左室短轴缩短率(LVFS)和左室重量指数(LVMI),采用免疫组化检测各组心肌组织基质金属蛋白酶-9(MMP-9)及基质金属蛋白酶抑制剂-1(TIMP-1)。结果与Sham组比,AMI组LVESD、LVEDD、LVMI明显升高(P分别<0.01、0.01、0.05),LVEF、LVFS明显降低(P均<0.01),心肌组织中MMP-9/TIMP-1明显升高(P均<0.01);与AMI组比,Cap组和Ros组LVESD、LVEDD、LVMI明显减少(P分别<0.01、0.01、0.05),EF、FS明显升高(P均<0.01),心肌组织中MMP-9/TIMP-1明显降低(P<0.01);Ros与Cap组上述指标相近(P均>0.05)。结论 Ros灌胃可抑制兔AMI后心室重构、改善心功能,其可能是通过调节心肌组织中MMP-9/TIMP-1而发挥作用。
