摘要
目的 探讨蛋白质质谱分析对急性心肌梗死病程不同时期的鉴别意义。方法 应用美国CipherGen公司金属亲和表面(IMAC3)芯片和蛋白芯片仪检测153例心肌梗死患者血清标本(其中刚入院45例,3h标本12例,6h标本22例,9h标本24例,12h标本24例,24h标本16例,48h标本10例)中的蛋白质相对含量。结果 不同时期急性心肌梗死患者在质荷比为4kD^12kD间有10种血清蛋白质含量有显著差异。不同时期的患者均被正确判断,准确率为100%(153/153),灵敏度和特异性分别为100%(45/45)和100%(108/108)。结论 该方法可快速、准确检测各期急性心肌梗死,灵敏度、特异性高。
Objective To approach the significance of serum protein fingerprinting on the identification of different courses of acute myocardial infarction. Methods For 153 patients of acute myocardial infarction, including 45 cases of just admitted patients, 12 cases of 3h admitted patients, 22 cases of 6h admitted patients, 24 cases of 9h admitted patients, 24 cases of 12h admitted patients, 16 cases of 24h admitted patients and 10 cases of 48h admitted patients. The relative contents of serum proteins were detected by IMAC3 chip and proteinchip reader (CipherGen Inc., VS). Results On the M/Z values ranged from 4KDa to 12KDa, ten protein contents were obviously different between the different courses of acute myocardial infarction. All the patients in different courses were diagnosed correctly, the accuracy was 100%(153/153). Both sensitivity and specificity were also 100% in learning mode. Conclusion Different courses of acute myocardial infarction patients can be quickly and correctly diagnosed by this method with high sensitivity and specificity. That will be widely used in clinical application
