摘要 目的研究缬沙坦对人冠脉内皮细胞(HCAEC)氧化应激过程中gp91Phox的影响。方法对照组:体外贴壁培养HCAEC,不进行其他干预;实验组:相同培养条件下加入缬沙坦(10μmol/L)培养24 h。应用Western blot法和细胞免疫荧光法测定两组细胞中gp91Phox的水平,对两组结果进行统计分析并比较。结果实验组HCAEC中gp91Phox的水平明显低于对照组,差异有统计学意义(P<0.01)。结论缬沙坦可以显著减少HCAEC中尼克酰胺腺嘌呤二核苷酸磷酸(NADPH)氧化酶亚基gp91Phox的表达,从而降低氧化应激水平。 Objective To study the effect on human coronary artery endothelial cells （HCAEC） gp91Phox in the process of oxidative stress by valsartan. Methods The control group： adherent culture HCAEC in vitro, no other intervention; the experimental group： under the same conditions with valsartan （ 10 μmol/L） train for 24 hours. U- sing Western blot and cell immunofluorescence measure gp91Phox levels in two groups of cells. The results were sta- tistically analyzed and compared in both groups. Results The experimental group gp91Phox level significantly lower than the control group in HCAEC （P 〈 0.01 ） , the difference was statistically significant. Conclusion Valsartan can significantly decrease the nicotinamide adenine dinucleotide phosphate（NADPH） oxidase subunit gp91Phox ex- pression in HCAEC, thus reduce oxidative stress level.
