Abstract
目的探讨益气降浊汤对病毒性心肌炎转化生长因子β1(TGF-β1)mRNA表达的影响.方法建立慢性病毒性心肌炎模型,通过4次梯度倍增CVB3m病毒感染小鼠,160只雄性昆明鼠分成空白组、模型组、中药治疗组、西药治疗组,分别于末次感染后10、30、60天处死小鼠,采用HE染色观察心肌病变,采用半定量RT-PCR法检测心肌组织中TGF-β1mRNA表达情况.结果HE染色显示各治疗组比模型组心肌病变明显减轻(P＜0.05),且TGF-β1 mRNA面积较模型组减少(P＜0.05).结论益气降浊汤能通过下调TGF-β1 mRNA表达,抑制心肌间质细胞外基质(ECM)的增生和重建,改善心脏病理变化,防止心肌炎后心室重构及向扩张型心肌病转化.
