摘　　要：目的探讨祛毒养心冲剂对病毒性心肌炎(VMC)的疗效及作用机制。方法将60只小鼠随机分为正常对照组、病毒组、药物组,每组20只。后两组小鼠每只腹腔注射柯萨奇病毒(CVB3)液,正常对照组腹腔注射不含病毒的Eagle′s液。药物组于接种病毒后24 h灌胃给予祛毒养心冲剂。21 d后,处死所有小鼠并取其心脏。进行心肌病理检查,采用实时荧光定量PCR法和免疫组化技术检测心肌组织中白细胞介素-6(IL-6)mRAN和蛋白的表达。结果与病毒组相比,应用祛毒养心冲剂治疗后,小鼠心肌组织病变积分显著下降(P<0.05),心肌组织中IL-6的表达明显降低(P<0.05)。结论祛毒养心冲剂对VMC具有明显治疗作用,其作用机制是通过抑制IL-6在心脏中的表达而实现的。Objective To investigate the effect and mechanism of Quduyangxinchongji on viral myocarditis. Methods Sixty male BABL/C mice were randomly divided into the control group, the virus group and the drug group, with 20 mice in each group. Mice in the second and third groups were intraperitoneally inoculated with coxsackievirus B3, while those in the control group were administrated with Eagle＇s without coxsackievirus B3. Also the drug group was subjected to Quduyangxinchongji in the stomach after coxsackievirus B3 infection. All mice were killed 21 days later and their hearts were removed for analysis, rFne levels of IL-6 mRNA expression and protein in the myocardium were respectively determined by real-time PCR and immunohistochchemistry technique. Resets As compared with the virus group, the myocardial histopathological scores and mRNA and protein expressions of IL-6 were significantly decreased in the drug group （ P 〈 0.05）. Conclusion Quduyangxinchongji might play a pivotal role in viral myocarditis by inhibiting the IL-6 expression in heart tissues.
