升陷汤及各单味药对阿霉素致心肌细胞损伤的保护作用

Protective effect of Shengxian decoction and each single herb component against adriamycin-induced cardiomyocyte injury

目的 研究升陷汤(SXT)及各单味药对阿霉素致心肌细胞损伤的保护作用。方法 将乳鼠缺氧/复氧培养的心肌细胞分为正常对照组(Con组)、阿霉素诱导损伤组(M组)和不同药物(升陷汤及其各单味药)治疗阿霉素诱导损伤组(SXT、A-E组)。检测指标包括细胞活力、细胞活性氧族(ROS)、Ca 2+和乳酸脱氢酶(LDH)水平。结果 与正常组相比,阿霉素能够造成心肌细胞损伤,与模型组比较,升陷汤全方以及各单味药实验组均能增强细胞的活力,降低细胞Ca 2+和LDH浓度;除桔梗和升麻外,升陷汤全方及其他单味药能够降低ROS的浓度,实验结果提示,在早期阿霉素治疗中如果应用升陷汤,一定程度上能降低阿霉素的心脏毒性作用。结论 升陷汤及各单味药对阿霉素致心肌细胞损伤具有保护作用。

Objective To study the protective effect of Shengxian decoction (SXT) and its each single herb component against doxorubicin induced cardiomyocyte injury. Methods Myocardial cells isolated from the neonatal rats with hypoxia/reoxygenation injury of cardiomyocytes were divided into eight groups,control group (Con group),doxorubicin-induced injury group (M group),and treatment groups with Shengxian decoction and its each single herb decoction (SXT,A-E groups) following doxorubicin-induced injury.The indicators tested included cell viability,cell ROS,Ca 2+ and LDH levels. Results Compared with the control group,doxorubicin induced obvious myocardial injury in model group.Compared with the model group,all tested drug groups increased the cell viability,reduced the levels of cell Ca 2+ and LDH.Besides,SXT and the single herb decoction reduced the concentration of ROS except the decoction of Platycodon grandiflorum and Cimicifuage Rhizoma.The experimental results suggested that the application of SXT in the early episode could reduce the cardiac toxicity of adriamycin to a certain extent. Conclusion SXT and its each single herb decoction showed protective effect against doxorubicin-induced cardiomyocyte injury.
