摘  要:目的:探讨CD45RA+调节性T细胞(CD45RA+Treg)在老年急性冠状动脉(冠脉)综合征患者中的作用。方法:入选100例老年冠心病患者,分为稳定型心绞痛组(SA组),不稳定型心绞痛组(UA组),非ST段抬高性心肌梗死组(NSTEMI组),ST段抬高性心肌梗死组(STEMI组);另外入选20例老年对照者(对照组)。流式细胞术检测各组外周血中CD45RA+Treg的表达,ELISA检测Treg相关的抗炎细胞因子IL-10和TGF-β1的表达。结果:老年冠心病患者各组CD45RA+Treg的表达较对照组均明显降低(均P<0.05);UA组和STEMI组CD45RA+Treg的表达较SA组又进一步减少(P<0.05),而NSTEMI组较SA组未见明显减少。UA组、NSTEMI组和STEMI组IL-10水平较对照组明显减少(均P<0.05)。结论:CD45RA+Treg对老年人群冠心病的发生有一定预测价值,尤其是对老年UA患者及STEMI的发生,其预测价值及临床意义可能更大。Objective:To study the role of CD45RA+ regulatory T cell (Treg) in old patients with acute coronary syndrome (ACS). Method: We evaluated circulating CD45RA+ Treg percentages by flow cytometry and the amount of IL-10, TGF β1 and IFN-γ by ELSA among old healthy subjects (control group) and old patients with stable angina (SA group), unstable angina (UA group), non ST elevated myocardial (NSTEMI group) and ST elevated myocardial (STEMI group). Result:Old patients with coronary heart disease (CHD) had lower percentages of CD45RA+ Treg compared to the controls (P〈0. 05). Furthermore, UA group and STEMI group showed significant reduction of CD45RA+ Treg than SA group (P〈0.05). Old patients with ACS including UA group, NSTEMI group and STEMI group had lower amount of IL-10 than the control group (P〈0.05). Conclusion: CD45RA+ Treg may be applied to predicate CHD, especially in patients with ACS.
