摘要 目的:观察不同浓度尿酸盐溶液对人血管内皮细胞(Endothelial cell of vessels,ECV)分泌肿瘤坏死因子-α(TNF-α)的影响。方法:体外培养人血管内皮细胞,分别用低、中、高(710μmol/L、1070μmol/L、1430μmol/L)等不同浓度的尿酸盐刺激,用ELISA技术观测尿酸盐对血管内皮细胞分泌TNF-α的影响。结果:低、中、高浓度尿酸盐刺激组细胞上清液中TNF-α浓度均较空白对照组明显上调,均具有显著性统计学差异(P均<0.05)。结论:说明尿酸盐能直接作用于人的血管内皮细胞,诱导细胞分泌肿瘤坏死因子-α(TNF-α),这也可能是其促进动脉粥样硬化斑块形成的重要机制之一。
