             [摘    要] 目的:探讨氧化应激⁃脂质代谢复合标志物血色素结合蛋白(hemopexin,Hpx)与载脂蛋白B(apolipoprotein B,apoB)
              的乘积(Hpx·apoB)与冠心病的关系,评估其在临床风险分层中的价值。方法:采用液相色谱⁃串联质谱法检测107例冠心病患
              者和33例非冠心病对照者血浆Hpx,收集临床资料后构建多因素Logistic回归模型,分析Hpx·apoB与冠心病的关联强度。通
              过受试者工作特征(receiver operating characteristic,ROC)曲线的曲线下面积(area under the curve,AUC)和净重分类指数(net
              reclassification index,NRI)评估模型预测效能。结果:冠心病组Hpx·apoB 值显著高于对照组(P < 0.01)。Hpx·apoB 值在急性
              心肌梗死、急性冠脉综合征和多支冠状动脉病变组中均显著升高(P均 < 0.01)。多因素Logistic回归分析显示,Hpx·apoB是冠
              心病的独立危险因素(OR=2.554,95%CI:1.336~4.881,P < 0.01)。ROC曲线显示其单独预测冠心病的AUC为0.667,与C反应
              蛋白(C⁃reactive protein,CRP)+低密度脂蛋白胆固醇(low⁃density lipoprotein cholesterol,LDL⁃C)联合后预测效能显著提升:
              ΔAUC=0.106(P < 0.05),NRI=15.6%(P < 0.05)。与临床风险模型整合后展现出更高的预测价值,整合 Framingham 评分:
              ΔAUC=0.076(P=0.139),NRI=27.0%(P < 0.01);整合 SCORE 评分:ΔAUC=0.142(P=0.093),NRI=37.55%(P < 0.001)。亚组分
              析显示,Hpx·apoB在男性、吸烟者和肾功能受损患者中对冠心病的预测能力更强(P < 0.05)。结论:Hpx·apoB作为氧化应激⁃
              脂质代谢的复合指标,可独立预测冠心病风险,与临床风险评分联合时显著改善风险预测效能。

             [Abstract] Objective:This study aims to explore the relationship between the oxidative stress⁃lipid metabolism composite biomarker
              Hpx·apoB[the product of hemopexin(Hpx)and apolipoprotein B(apoB)]and coronary artery disease(CAD),and evaluate its value in
              clinical risk stratification. Methods:The study utilized liquid chromatography⁃tandem mass spectrometry to quantify plasma Hpx levels
              in 107 CAD patients and 33 controls without CAD,collected the clinical data,and constructed a multivariate logistic regression model to
              analyze the association strength between Hpx·apoB and CAD. The predictive efficacy of the model was evaluated by area under the
              receiver operating characteristic(ROC)curve(AUC)and net reclassification index(NRI). Results:The Hpx·apoB value in the CAD
              group was significantly higher than that in the control group(P < 0.01). The Hpx·apoB value was significantly increased in patients with
