摘要: 目的 观察抗柯胶囊总皂苷抑制柯萨奇病毒B型(CVB)诱导细胞凋亡的作用,探讨其可能的机制。方法 通过接种病毒液的方式建立体外细胞感染模型,采用细胞病变效应法(CPE)测定抗柯胶囊总皂苷对CVB3、CVB4、CVB5株50%抑制浓度(IC50)及治疗指数(TI);CCK-8试剂盒检测细胞存活情况;TdT介导的dUTP缺口末端标记技术(TUNEL法)测定心肌细胞凋亡率;蛋白免疫印迹法(Western-blot)检测大鼠原代心肌细胞中Bcl-2、Bax蛋白表达情况。结果 抗柯胶囊总皂苷可明显抑制CVB3、CVB4、CVB5致细胞病变,对CVB3、CVB4、CVB5的IC50分别为223.34、315.48、306.53 μg·mL-1,治疗指数分别为4.68、3.24、3.24;390.63、195.32、97.66 μg·mL-1剂量组可明显提高3种病毒感染后心肌细胞的存活率,抑制心肌细胞凋亡。抗柯胶囊总皂苷对CVB3病毒复制有明显抑制作用,390.63、195.32 μg·mL-1 2个剂量组可使凋亡关键因子Bcl-2表达增加,Bax表达降低,Bcl-2/Bax比值升高,与病毒对照组比较有显著差异(P<0.05, P<0.01)。结论 抗柯胶囊总皂苷可以改善CVB致心肌细胞病变,提高细胞存活率,减少细胞凋亡,其机制与抑制病毒复制、调控心肌细胞中凋亡相关蛋白表达相关。

Abstract: Objective To observe the inhibitory effects of saponins from Kangke capsules on apoptosis caused by Coxsackievirus B (CVB), and to explore the mechanism. Methods CVB was inoculated into cardiomyocytes to establish an infection model in vitro. The cytopathic effect method (CPE) was adopted to determine the 50% inhibitory concentration (IC50) and therapeutic index (TI) of saponins from Kangke capsules on CVB3, CVB4 and CVB5. CCK-8 kit was used to detect cell viability. TdT-mediated dUTP notch end labeling technique (TUNEL) was used to determine the apoptosis rate of cardiomyocytes. Western-blot was used to study the expressions of Bcl-2 and Bax protein in primary rat cardiomyocytes. Results Saponins from Kangke capsules could significantly alleviate cytopathy induced by CVB. The IC50 for CVB3, CVB4, and CVB5 was 223.34, 315.48 and 306.53 μg·mL-1 respectively, while the therapeutic index was 4.68, 3.24 and 3.24 respectively. The doses of 390.63, 195.32, and 97.66 μg·mL-1 could increase the survival rate of cardiomyocytes after viral infection. Saponins from Kangke capsules could significantly inhibit viral replication and cell apoptosis after infection while increasing the expression of Bcl-2, decreasing the expression of Bax, and elevating the Bcl-2/Bax ratio. Conclusion Saponins from Kangke capsules can improve cytopathy caused by CVB infection, improve cell survival rate, and inhibit apoptosis. The mechanism is related to the regulation of apoptosis-related protein expressions in cardiomyocytes.
