摘要 目的:观察培哚普利联合厄贝沙坦对扩张型心肌病(DCM)大鼠心功能及心肌的骨骼肌型α-肌动蛋白(α-actin)表达的影响。方法:通过腹腔注射阿霉素建立大鼠DCM模型。13周后,大鼠分为4组:A组为正常大鼠;B、C、D组均为DCM大鼠。A、B组不予药物干预,C组予以培哚普利,D组予以培哚普利联合厄贝沙坦。超声心动图测定左室射血分数(LVEF);RT-PCR方法检测骨骼肌型α-actin mRNA表达;免疫组化方法检测骨骼肌型α-actin蛋白的表达。结果:药物治疗3周后:①D组LVEF高于C组(P<0.05);②D组骨骼肌型α-actin mRNA及蛋白表达水平均低于C组(P<0.05)。结论:与单用培哚普利比较,培哚普利联合厄贝沙坦更明显改善DCM大鼠心功能,同时伴随心肌骨骼肌型α-actin表达更明显下调。
