摘要
目的:观察麝香保心丸(SXBXW)对血管平滑肌细胞表型转化的影响。方法:以血管平滑肌细胞系RASMCP8为模型,设对照组,SXBXW0.25、0.5、1.0和2.0g/L组,经不同浓度的SXBXW作用后,用流式细胞术测定RASMCP8细胞的收缩型特异性分子标志物α-平滑肌肌动蛋白(α-SMA)和平滑肌肌球蛋白重链(SM-MHC)表达的变化。结果:与对照组相比,经SXBXW处理后,α-SMA和SM-MHC的阴性细胞百分比降低,阳性细胞百分比增加。结论:SXBXW能促使血管平滑肌细胞的表型从合成型向收缩型转化。
AIM: To observe the effects of She xiang bao xin wan (SXBXW) of Chinese patent drug on the phenotype transformation of vascular smooth muscle cells.METHODS: The vascular smooth muscle cell line RASMC P8 was used as the cell model in this experiment. The cells were treated with SXBXW at the doses of 0.25 g/L, 0.50 g/L, 1.0 g/L and 2.0 g/L, respectively, and control cells were treated with the same volume of culture medium without SXBXW. The expression of α-smooth muscle actin (α-SMA) and the smooth muscle myosin heavy chain (SM-MHC), which served as specific molecular markers of vascular smooth muscle contraction in RASMC P8 cells, was analyzed by flow cytometry. RESULTS: The percentages of α-SMA and SM-MHC negative cells in SXBXW treated groups were lower than those in control group. Meanwhile, the percentages of α-SMA and SM-MHC positive cells were increased in RASMC P8 cells treated with SXBXW, indicating that SXBXW prompted the transformation of RASMC P8 cells from synthetic to contractile phenotype.CONCLUSION: Chinese patent drug SXBXW plays a role in transforming the cell phenotype from synthetic to the contraction in vascular smooth muscle.
