摘要: 目的 探讨 CD40/CD40L 在冠心病发生发展中的作用, 以及环孢素 A(CsA)对 CD40/CD40L 是否具有抑制作用。方法 71 例冠心病或疑诊为冠心病患者分为急性心肌梗死 (AMI) 组 19 例, 不稳定型心绞痛 (UAP) 组 18 例,稳定型心绞痛 (SAP) 组 17 例, 正常对照 (N) 组 17 例。提取各组患者外周血单个核细胞 (PBMCs), 应用流式细胞术检测各组 CD40/CD40L 表达水平, 筛选出 CD40/CD40L 高表达组并给予不同浓度 CsA (H1:0 mg/L; H2:0.01 mg/L; H3:0.1 mg/L; H4:1 mg/L)处理细胞, 流式细胞术检测处理组 CD40/CD40L 的表达水平。结果 与 N 组相比, 其他 3 组 CD40 表达水平均升高 (均 P < 0.05), UAP 组、 AMI 组较 SAP 组升高, UAP 组与 AMI 组之间差异无统计学意义 (P > 0.05); CD40L 的表达在不同病变程度组间依次升高, 两两比较差异均有统计学意义 (P < 0.05)。AMI 组 CD40/CD40L 表达水平最高。不同浓度 CsA 处理后 H1 组 CD40 表达率高于 H3 组、 H4 组 (均 P < 0.05)。CD40L 表达率在 H1 组显著高于其他 3 组(均 P < 0.05)。结论 CD40/CD40L 可能参与冠心病的发生发展, CsA 可通过抑制 CD40/CD40L 从而延缓冠心病发展及改善预后。

Abstract: Objective To investigate the effect of CD40/CD40 ligand on the genesis and development of coronary artery disease (CAD), and the inhibitory effect of cyclosporine A (CsA) on CD40/CD40 ligand. Methods A total of 71 patients were divided into four groups: acute myocardial infarction group (AMI, n=19), unstable angina pectoris group (UAP, n=18), stable angina pectoris group (SAP, n=17) and normal control group (N, n=17). Flow cytometry was used to detect the expression of CD40 and CD40L in peripheral blood mononuclear cells (PBMCs) of four groups. The group in which CD40 and CD40L were produced at the highest level was chosen, and a series concentrations of CsA(H1:0 mg/L, H2:0.01 mg/ L, H3: 0.1 mg/L, H4:1 mg/L) were used to treat the cells. Then the expressions of CD40 and CD40L were measured by flow cytometry. Results Compared with N group, the expression of CD40 was significant higher in other groups (P < 0.05). The expression of CD40 was significant higher in UAP group and AMI group than that of SAP group. There was no significant difference in the expression of CD40 between UAP group and AMI group (P > 0.05). The expression of CD40L was elevated and fol⁃ lowed by different severity of CAD. There was significant difference in the expression of CD40L between groups (P < 0.05) . AMI group showed the highest expression of CD40 and CD40L. After being treated with CsA, the expression of CD40 was higher in H1 group than that of H3 group and H4 group (P < 0.05). The expression of CD40L was significantly higher in H1 group than that of other three groups (P < 0.05). Conclusion CD40 and CD40L may be involved in the development of CAD. Moreover, it might be restrained by CsA via regulation of CD40/CD40L.
