  摘要目的:研究生脉饮对病毒性心肌炎心肌细胞凋亡作用的影响。方法:用柯萨奇B病毒建立感染的心肌细胞模型,在感染后24小时将细胞分为正常对照组、病理模型组、生脉饮组和辅酶Q10组。4组分别在不同时间点观察细胞形态,并采用TUNEL法进行细胞凋亡的检测。结果:在48小时点开始检测,正常对照组无细胞凋亡,生脉饮组及辅酶Q10组均有凋亡,生脉饮组凋亡率低于辅酶Q10组(P<0.05),论文范文病理模型组随着时间的推移,凋亡率增加,72小时点明显高于48小时点(P<0.01),与药物干预组比较差异具有统计学意义(P<0.05)。结论:生脉饮能够有效抑制病毒性心肌炎心肌细胞的凋亡,且应该早期干预。

  AbstractObjective:To study the effect of pulse-activating decoction compound preparation in myocardial apoptosis effect of viral myocarditis.Methods:Using coxsackie B virus established infectious myocardial cell model.In 24 hours after infection,the cells were divided into four groups:the normal control group,the pathological model group,the pulse-activating decoction group and the coenzyme Q10 group.The cellular morphology of four groups of cells were observed at different time points.The apoptosis was detected by TUNEL method.Results:Begin testing at 48 hours,the normal control group had no apoptosis;the pulse-activating decoction group and the coenzyme Q10 group all had apoptosis;the apoptosis rate of the pulse-activating decoction group was lower than that of the coenzyme Q10 group(P<0.05).In the pathological model group,the apoptosis rate was increased as time goes on.72 hours point was obviously higher than 48 hours point(P<0.01).There had statistically significant compared with the drug intervention group (P<0.05).Conclusion:Pulse-activating decoction can effectively inhibit the myocardial cell apoptosis of viral myocarditis,and it should be early intervented.

  病毒性心肌炎(viral myocarditis,VM)是指病毒感染引起的心肌局限性或弥漫性的急慢性炎性病变,多由柯萨奇病毒引起。在柯萨奇病毒导致VM的病理机制研究中,越来越多的证据表明,柯萨奇病毒导致病毒性心肌炎心肌细胞凋亡,从而出现心肌坏死病变[1]。中医学认为VM属于“心悸”“怔忡”范畴,病机中多存在气阴两虚,治疗上以益气养阴为主,多采用生脉饮进行加减治疗,其组成为人参、麦冬、五味子。生脉饮治疗VM临床疗效确切,但其干预机制尚不明确,且临床上生脉饮是否应该早期应用一直是临床争议的问题。为此,本实验拟观察生脉饮对VM心肌细胞凋亡的影响,力求明确生脉饮的作用机制以及最佳时间,为临床准确使用提供参考。
