摘要
目的探究血清氧化低密度脂蛋白(oxLDL)、补体C1q/肿瘤坏死因子相关蛋白5(CTRP5)、单核细胞趋化蛋白-1(MCP-1)表达水平与高血压颈动脉粥样硬化(CAS)的相关性。方法选取143例高血压患者为研究对象,根据颈动脉内膜中层厚度(CIMT)将其分为正常组(n=61)和CAS组(n=82),另选同期体检的87例健康者作为对照组。ELISA法测定血清oxLDL、CTRP5、MCP-1水平;血清oxLDL、CTRP5、MCP-1水平与CIMT的关系用Pearson相关性分析法;logistic回归法探究高血压患者发生CAS的影响因素;血清oxLDL、CTRP5、MCP-1对高血压CAS的诊断价值使用受试者工作特征(ROC)曲线进行探究。结果对照组、正常组、CAS组血清oxLDL、CTRP5、MCP-1水平依次升高(P<0.05)。Pearson结果显示血清oxLDL、CTRP5、MCP-1与CIMT呈显著正相关(r=0.526、0.592、0.646,P<0.05)。logistic回归分析结果显示:同型半胱氨酸(Hcy)、高密度脂蛋白(HDL-C)、oxLDL、CTRP5、MCP-1均为高血压患者发生CAS的影响因素(P<0.05)。oxLDL、CTRP5与MCP-1联合诊断的AUC均显著大于oxLDL、CTRP5和MCP-1的单独诊断(P<0.05)。结论血清oxLDL、CTRP5、MCP-1水平在高血压CAS患者中均升高,3者表达水平与CIMT呈正相关,且3者在诊断高血压CAS具有较高诊断效能。
Objective The aim of this study is to determine the correlation between serum oxidized low-density lipoprotein(oxLDL),complement C1q/tumor necrosis factor related protein 5(CTRP5)and monocyte chemotactic protein-1(MCP-1)and hypertensive carotid atherosclerosis(CAS).Methods Based on the carotid intima-media thickness(CIMT),143 hypertensive patients were divided into two groups:a normal group(n=61)and a CAS group(n=82).Additionally,87 healthy individuals who underwent physical examinations were included in the control group.ELISA method was applied to measure serum levels of oxLDL,CTRP5,and MCP-1.The relationship between serum oxLDL,CTRP5,MCP-1 levels and CIMT was analyzed using Pearson correlation method.Logistic regression method was applied to explore the influencing factors of CAS occurrence in hypertensive patients.The diagnostic value of serum oxLDL,CTRP5,and MCP-1 in hypertensive CAS was investigated using receiver operating characteristic(ROC)curves.Results The levels of serum oxLDL,CTRP5,and MCP-1 in the control group,normal group,and CAS group all increased sequentially(P<0.05).Pearson analysis showed a significant positive correlation between serum oxLDL,CTRP5,MCP-1 and CIMT(r=0.526,0.592,0.646,P<0.05).Logistic regression analysis suggested that homocysteine(Hcy),high-density lipoprotein(HDL-C),oxLDL,CTRP5,and MCP-1 were all influencing factors for the occurrence of CAS in hypertensive patients(P<0.05).The AUC of oxLDL,CTRP5 and MCP-1 combined diagnosis was significantly higher than that of each index alone diagnosis(P<0.05).Conclusion The levels of serum oxLDL,CTRP5,and MCP-1 are all elevated in hypertensive CAS patients,and their expression levels are positively correlated with CIMT.Moreover,these three factors demostrate high diagnostic efficacy in diagnosing hypertensive CAS.
