摘    要:目的观察冠状动脉造影患者外周血单个核细胞Toll样受体(TLR)1~10的表达状况及其与冠状动脉病变程度的关系。方法冠状动脉造影患者436例,根据冠状动脉病变支数,分为多支病变组93例、双支病变组172例、单支病变组98例和冠状动脉造影正常的对照组73例,用流式细胞术检测外周血单个核细胞TLR1~10的表达。用Gensini评分系统对冠状动脉造影结果进行评分。观察TLR1~10在各组中的阳性率的情况,用相关分析研究TLR1~10阳性率与冠状动脉Gensini评分的关系。结果外周血单个核细胞TLR2~6在多支病变组、双支病变组、单支病变组表达的阳性率均显著高于对照组,TLR2(86.36±13.45)%,(81.74±12.68)%,(72.89±10.37)%vs(60.76±11.56)%(均P〈0.01);TLR3(7.05±2.47)%,(6.94±2.83)%,(7.01±2.21)%vs(5.25±2.06)%(均P〈0.05);TLR4(39.83±8.34)%,(37.17±8.02)%,(30.35±9.78)%vs(25.86±6.48)%(P〈0.01或〈0.05);TLR5(18.10±4.46)%,(17.31±4.92)%,(13.62±4.25)%vs(11.34±3.77)%(P〈0.01或〈0.05);TLR6(9.71±3.60)%,(9.43±3.25)%,(8.62±3.53)%vs(6.84±3.19)%(均P〈0.01)。其中TLR2、4、5在多支病变组、双支病变组的表达阳性率均显著高于单支病变组(均P〈0.01),其他亚型在各组间差异无统计学意义。相关分析显示,外周血中单个核细胞TLR2~6表达的阳性率与冠状动脉Gensini评分呈正相关,其相关系数分别为0.473,0.327,0.646,0.516,0.304(P〈0.05或〈O.01)。结论冠状动脉病变患者外周血中单个核细胞TLR2~6表达的阳性率增多,TLR2、4、5可反映冠状动脉病变的广泛性;冠状动脉的病变程度与TLR2~6的表达有关。

Abstract:Objective To investigate the expression Toll-like receptor(TLR2) 1-10(10 subtypes) on human peripheral blood mononuclear cells in subjects undergoing coronary angiography and analyze the relationship between the positive rates of TLR 1-10 and the severity of coronary artery stenosis.Methods 436 subjects were enrolled.All subjects underwent coronary angiography and were divided into four groups according to the number of coronary artery damage:single vessel damage group(SVD,n=98),double vessels damage group(...
