摘要: 目的 探讨鞘磷脂酶(sMase)和肿瘤坏死因子α(TNF-α)在类风湿性关节炎(RA)患者发生动脉粥样硬化(AS)中的临床意义。方法 用TNF-α刺激培养的人脐带静脉血管内皮细胞(EC),检测上清液中sMase活性。对124例RA患者[单纯RA组66例、RA合并冠心病(CHD)组58例]和相应对照组检测血清sMase活性、TNF-α浓度水平。结果 经TNF-α刺激后EC的sMase活性显著升高;RA组患者血清sMase活性高于对照组,尤其是RA合并CHD组;单纯RA组和RA合并CHD组患者血清TNF-α活性高于对照组。结论 TNF-α刺激ECsMase活性增加。RA患者TNF-α和sMase活性增高与血管内皮损伤有关,sMase有可能成为血管内皮功能障碍(ECD)的实验室诊断指标之一。

Abstract: Objective To investigate the clinical significance of sphingomyelinase(sMase)and tumor necrosis factor-alpha(TNF-α)in patients with rheumatoid arthritis(RA)and atherosclerosis(AS). Methods The cultured human umbilical cord vein vascular endothelial cells(EC)were stimulated by TNF-α, and the activity of sMase in the supernatant was detected. The serum sMase activity and TNF-α levels were detected in 124 RA patients [66 patients with only RA and 58 RA patients also with coronary heart disease(CHD)] and the corresponding control group. Results The sMase activity of EC increased significantly after the stimulation of TNF-α. The serum sMase activity of RA group was higher than that of control group,especially the activity of RA combined CHD group was the highest. The serum TNF-α levels of only RA group and RA combined CHD group were higher than that of control group. Conclusions The sMase activity of EC increases with the stimulation of TNF-α. The increases of TNF-α level and sMase activity in RA patients are related to vascular endothelial damage. Therefore,sMase activity may become one of the laboratory diagnostic indicators of vascular endothelial cell dysfunction(ECD).
