摘要

摘要: 目的：探讨冠状动脉（冠脉）粥样硬化性心脏病（CHD）患者外周血淋巴细胞表面CD1分子的表达特点及其与血脂的相关性。方法：收集2017-11-2018-02于湖北医药学院附属东风医院心内科行冠脉造影检查的患者117例，根据冠脉造影检查发现冠脉狭窄是否≥ 50%分为CHD组（64例）和对照组（53例）。采用流式细胞术检测2组患者外周血淋巴细胞表面CD1分子的表达情况，并对2组患者的CD1分子、血脂水平进行分析。结果：CHD患者外周血淋巴细胞表面CD1b的表达显著高于对照组，差异有统计学意义（P<0.05）；CD1b及CD1d分子的表达与三酰甘油水平呈显著负相关（r=-0.241，P=0.010；r=-0.204，P=0.030）。结论：CD1分子的高表达可能提示其参与了CHD的发病过程，这一机制可能与CD1b的分子结构及其参与的炎症反应相关，且与CD1分子识别并呈递脂质抗原密切相关。

Abstract: Objective: To investigate the expression characteristics of CD1 molecules on the peripheral blood lymphocytes in patients with coronary atherosclerotic heart disease(CHD)and explore the possible mechanisms of CD1 molecules participating in the pathogenesis of CHD.Method: A total of 117 cases were collected who had received coronary angiography examination in the Department of Cardiology, affiliated Dongfeng Hospital, Hubei University of Medicine, from November 2017 to February 2018.According to the results of coronary angiography, cases were divided into CHD group (64 cases) and control group (53 cases) by whether the coronary artery stenosis was great than 50%.The expression of CD1 molecule on peripheral blood lymphocyte surface was detected by flow cytometry and the levels of CD1 molecule and blood lipid were analyzed.Result: The expression of CD1b on peripheral blood lymphocyte surface in patients with coronary artery disease is significantly higher than that in the control group (P<0.05).The expression of CD1b and CD1d is negatively correlated with triglyceride level (r=-0.241, P=0.010;r=-0.204, P=0.030).Conclusion: The high expression of CD1b molecule may indicate that this molecule participates in the pathogenesis of CHD and underlying mechanism may include that the molecular structure of CD1b and its involvement in the inflammatory responses, as well as the recognition and presentation of lipid antigen by CD1 molecule.
