冠心病病人血清HMGB1与hs-CRP变化及临床意义

目的探讨冠心病(CHD)病人血清高迁移率族蛋白B1(HMGB1)和超敏C反应蛋白(hs-CRP)的变化及其临床意义。方法采用ELISA法和散射速率比浊法,测定60例不同类型CHD病人血清HMGB1和hs-CRP浓度变化,并与20例健康体检者(对照组)进行比较。结果 CHD病人血清HMGB1和hs-CRP水平明显增高,与对照组比较差异有显著性(t′=8.02、8.43,P<0.01)。急性心肌梗死(AMI)病人血清HMGB1和hs-CRP水平均显著高于不稳定型心绞痛(UAP)病人、稳定型心绞痛(SAP)病人和对照组(F=31.48、24.60,q=4.32~12.84,P<0.01);UAP病人血清HMGB1和hs-CRP水平显著高于SAP病人和对照组(q=3.98~8.51,P<0.01);SAP病人血清HMGB1和hs-CRP水平与对照组比较差异亦有显著性(q=3.63、2.90,P<0.05)。CHD病人血清HMGB1和hs-CRP水平呈正相关(r=0.287,P<0.05)。血清HMGB1和hs-CRP水平在AMI、UAP组AUCROC均大于0.90,对AMI诊断的灵敏度和特异度分别为0.90、0.95和0.85、0.95,对UAP诊断的灵敏度和特异度分别为0.95、0.85和0.90、0.90。结论血清HMGB1和hs-CRP浓度的变化对AMI和UAP具有明显的诊断价值和较高的诊断准确度,可以作为评价CHD危险程度的指标之一。

THE CHANGES AND REALTED CLINICAL SIGNIFICANCE IN SERUM LEVELS OF HIGH-MOBILITY GROUP BOX 1 PROTEIN AND HYPERSENSITIVE C-REACTIVE PROTEIN IN PATIENTS WITH CORONARY HEART DISEASE

Objective To explore the changes of serum levels of high-mobility group box l protein(HMGB1) and hypersensitive C-reactive protein(hs-CRP) in patients with coronary heart disease(CHD) and to discuss the related clinical significance.Methods The serum levels of HMGB1 and hs-CRP were detected by enzyme-linked immunosorbent assay and scatter velocity turbidimetry,respectively,among 60 patients with different types of CHD.The data obtained were compared with 20 healthy controls. Results The serum HMGB1 and hs-C...
