炎性相关细胞因子水平与老年人急性冠状动脉综合征的关系

目的探讨炎性细胞因子与老年人急性冠脉综合征(ACS)的关系。方法应用夹心酶联免疫吸附法(ELISA)、单克隆荧光抗体标记法检测ACS组33例、稳定性劳力型心绞痛(SA)组24例及健康对照组20例外周血中单核细胞趋化因子-1(MCP-1)、可溶性细胞间黏附分子-1(sICAM-1)、单核细胞表面CD11b及P-选择素(CD62p)水平。结果(1)ACS组、SA组与对照组比较,MCP-1〔(85.78±33.79)(、56.96±22.47)μg/L对(39.16±14.17)μg/L〕、sICAM-1〔(561.29±93.16)(、496.49±73.55)μg/L对(359.19±110.78)μg/L〕、CD11b〔(227.17±67.13)(、118.05±24.19)MFI对(86.81±40.93)MFI〕、CD62p〔(36.03±9.30)、(14.19±6.49)对(4.25±2.59)%〕均值之间的差异均具有统计学意义(P<0.01),以ACS组中4种炎性因子水平最高,SA组次之,对照组最低。(2)不稳定型心绞痛(UA)组20例和急性心肌梗死(AMI)组13例的4种炎性因子检测指标,其均值之间的差异均无统计学意义(P>0.05)。(3)SA组、UA组和AMI组冠状动脉病变程度之间的差异均无统计学意义(P>0.05)。结论外周血中炎性细胞因子可能参与了ACS发病过程。

Relationship between the levels of inflammation-related cytokines and acute coronary syndrome in elderly patients

Objective By measuring the levels of serum MCP-1,sICAM-1 and expression of monocyte CD11b and CD62p in order to investigate the effects of these inflammation mediators on acute coronary syndrome and the relationship between inflammatory mediators and degree of coronary artery stenosis. Methods By means of enzyme-linked immunosorbent assay(ELISA) technique and flow cytometry technique,the changes of concentration of MCP-1,sICAM-1 and expression of CD11b and CD62p were measured in patients with acute coronary syndrome(ACS,n=33) group,stable angina(SA,n=24) group and control group(n=20)in the study. Results (1) The concentration of MCP-1 and sICAM-1 and expression of CD11b and CD62p had significant difference in statistics among three groups.Four inflammatory mediators were the highest in ACS group and the lowest in control group.(2)There were no significant differences in the levels of MCP-1,sICAM-1,CD11b,CD62p between AMI group and UA group.(3)There were no significant differences in the degree of coronary artery stenosis amomg SA,UA and AMI groups. Conclusions The results of the present study suggest that inflammation might play a role in the pathogenesis of coronary artery disease.
