Abstract: 目的研究中药芪芍五味子复方制剂抗柯萨奇B3病毒(CVB3)效果及抑制病毒性心肌炎小鼠心肌细胞凋亡的机制。方法采用细胞培养法观察细胞病变效应(CPE)与广谱抗病毒药物病毒唑对照,进行复方制剂体外抗病毒实验;BALB/c小鼠接种CVB3建立病毒性心肌炎动物模型,随机分为正常对照组、病毒对照组、复方制剂治疗组和维生素C与病毒唑联用组,观察各组心肌病理变化,Real-time定量PCR检测小鼠心肌CVB3RNA水平,流式细胞仪检测心肌细胞凋亡和坏死率。结果复方制剂体外最大无毒浓度为19.53g/L,预防给药、同时给药和治疗给药3种方式细胞培养所需有效药物浓度均低于病毒唑;与同期病毒对照组小鼠比较,复方制剂治疗组小鼠心肌炎症性病理变化明显减轻,CVB3RNA拷贝数降低(P<0.05),心肌细胞凋亡和坏死率显著降低(P<0.05)。结论芪芍五味子复方制剂可有效抗病毒,抑制病毒诱导心肌细胞凋亡,对CVB3感染小鼠心肌有良好的保护作用。
