摘要 目的观察四妙勇安汤对体外培养的人脐静脉内皮细胞(HUVEC)缺氧损伤模型的影响。方法实验分为3组,即正常组、模型组、四妙勇安汤组,后2组建立体外细胞缺氧模型,用四甲基偶氮唑蓝(MTT)实验观察四妙勇安汤对缺氧内皮细胞存活率的影响,测定四妙勇安汤对缺氧内皮细胞乳酸脱氢酶(LDH)漏出量的影响,并用免疫荧光法检测细胞中血管内皮生长因子(VEGF)生成量的表达。结果四妙勇安汤能显著增加MTT实验中各孔吸光度值,降低LDH漏出量,增加VEGF的生成量。结论四妙勇安汤具有保护缺氧的HUVEC损伤的作用,其作用机制与增加细胞活性、降低缺氧造成的细胞毒性、增加VEGF的表达、促进血管新生的作用有关。 Objective To study the effect of Simiaoyongantang on human umbilical vein endothelial cells (HUVECs) injury induced by hypoxia. Methods The HUVECs were divided into normal group, model group and Simiaoyongantang group, and the hypoxia model was established at the latter two groups. The livability of HUVECs was measured by MTT assay. The transudation of LDH in the medium was measured by biochemistry and the positive expression of VEGF was detected by immunofuorescence chemistry. Results The level of LDH was reduced significantly and the cell activity indicated by MTT was increased. The number of the cells stained by VEGF increased in the treatment group of Simiaoyongantang. Conclution Simiaoyongantang has protective effect on hypoxia injured HUVECs, which may be related to its effect of increasing the cells livability, reducing the injury induced by hypoxia, up-regulating expressions of VEGF and promoting angiogenesis.
