冠心病病人血清sgp130与hs-CRP变化及其意义

目的探讨冠心病(CHD)病人血清可溶性糖蛋白130(sgp130)和超敏C反应蛋白(hs-CRP)的变化及其临床意义。方法采用ELISA和散射速率比浊法检测了20例急性心肌梗死(AMI)病人、20例不稳定型心绞痛(UAP)病人、20例稳定型心绞痛(SAP)病人血清sgp130、hs-CRP水平的变化,并与20例健康体检者(对照组)进行比较。结果CHD病人血清sgp130水平明显降低,血清hs-CRP水平明显增高,与对照组比较,差异有显著性(t=6.97、6.86,P<0.01)。AMI、UAP及SAP病人sgp130和hs-CRP水平比较,差异有显著性(F=47.14、36.23,q=4.26-15.66,P<0.01)。AMI病人血清sgp130、hs-CRP水平均低于或高于UAP病人、SAP病人和对照组(q=4.59-15.66,P<0.01);UAP病人血清sgp130、hs-CRP水平显著低于或高于SAP病人和对照组(q=4.26-11.06,P<0.01);SAP病人血清sgp130水平与对照组之间亦有统计学差异(q=4.93,P<0.01)。CHD病人血清sgp130与hs-CRP水平呈负相关(r=-0.574,P<0.01)。血清sgp130、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0.95、0.90和0.90、0.95,对UAP诊断的灵敏度和特异度分别为0.95、0.90和0.90、0.95。结论血清sgp130、hs-CRP浓度的变化对AMI和UAP具有较高的诊断准确度,其变化的程度可以作为炎症反应和病情严重的判断指标之一。

THE CHANGES OF SERUM SOLUBLE GLYCOPROTEIN-130 AND HYPERSENSITIVE C-REACTIVE PROTEIN AND THEIR SIGNIFICANCE IN PATIENTS WITH CORONARY HEART DISEASE

Objective To explore the clinical significance of changes in serum levels of soluble glycoprotein-130 (sgp130) and hypersensitive C-reactive protein (hs-CRP) in patients with coronary heart disease (CHD). MethodsBy using enzyme-linked immunosorbent assay (ELISA) and light scattering rate nephelometry method, levels of sgp130 and hs-CRP were measured in 20 patients with acute myocardial infarction (AMI), 20 unstable angina pectoris (UAP), and 20 stable angina pectoris (SAP). The results were compared with th...
