摘要 目的:观察利心I号对阿霉素所致充血性心力衰竭大鼠心肌细胞凋亡的影响,探讨其作用机制。方法:利用阿霉素的心肌毒性,复制充血性心力衰竭的动物模型。将84只Wistar雄性大鼠随机平均分为6组:正常对照组、模型组、依那普利对照组、心宝对照组、利心I号低剂量组、利心I号高剂量组。采用免疫组化法测定大鼠心肌细胞凋亡基因Bax、Bcl-2的表达。结果:各治疗组均能抑制充血性心力衰竭大鼠心肌细胞Bax基因的表达,以中药高剂量组和西药对照组效果为优。同时各治疗组能够促进大鼠心肌细胞Bcl-2基因的表达,与模型组比较具有显著性差异,P<0.05或P<0.01,其中以利心I号高剂量组为优。结论:利心I号可能通过调控凋亡基因而抑制心肌细胞凋亡,从而延缓或部分逆转心室重塑的发生、发展,而起到治疗充血性心力衰竭的作用。
