纤溶酶原激活物抑制剂-1 在脓毒症致 DIC 的早期诊断价值
张雅静(北京京煤集团总医院,北京 102300)
【摘要】目的:探讨纤溶酶原激活物抑制剂-1(Plasminogen activator inhibitortype-1,PAI-1)
在脓毒症所致弥散性血管内凝血(Disseminated intrascular coagulation,DIC)中的早期诊断价
值。方法:纳入 85 例临床诊断为脓毒症的患者的临床病例资料,并根 ISTH 诊断标准分为
DIC 组和非 DIC 组,采用酶免法检测其血 PAI-1 值,评估其 DIC 早期诊断中的价值。结果:
在 DIC 患者中,其血 PAI-1 值在第 1、3、7 天较非 DIC 组均有显著升高(P<0.05);受试
者工作曲线(ROC)分析提示 PAI-1 在患者中第 1、3、7 天的 AUC 面积分别为 0.746(95%CI
0.553~0.875)、 0.913(95%CI 0.831~0.965)、 0.884(95%CI 0.712~0.953);皮尔逊相关性分析
则发现血 PAI-1 值与 SOFA 评分、APACHEⅡ评分存在显著相关性(P<0.05)。 结论:血 PAI-
1 值可用于脓毒症所致 DIC 的早期诊断,为临床早期干预和治疗提供最佳时机。

The Value of F-lysogen-activator Inhibitor-1 in The Early Diagnosis of DIC in Sepsis
Yajing Zhang(Beijing Coal Group General Hospital, Beijing 102300)
[Abstract] Objective: To explore the early diagnostic value of plasminogen activator
inhibitortype-1 (PAI-1) in disseminated intravascular coagulation (DIC) in sepsis. Methods:
Eighty-five patients with sepsis were divided into DIC group and non-DIC group according to the
ISTH, and their blood PAI-1 value was detected by enzyme immunoassay to evaluate its value in
early diagnosis of DIC. Results: The level of PAI-1 in DIC patients was significantly higher than
that in non-DIC group on the 137th day (P < 0.05); The AUC area of PAI-1 on day 137th was 0.746
(95% CI 0.553 ~ 0.875) 0.913 (95% CI 0.831 ~ 0.965) 0.884 (95% CI 26.43); Pearson correlation
analysis showed that there was significant correlation between serum PAI-1 and SOFA score and
APACHE ⅱ score (P < 0.05) . Conclusion: The value of blood PAI-1 can be used in the early
diagnosis of DIC caused by sepsis and provide the best time for early intervention and treatment.

弥漫性血管内凝血(Disseminated intrascular coagulation,DIC)涉及广泛和持续的凝血激活,
最终导致全身小血管出现弥漫性微血栓。先前的研究表明,约有 20-40%的脓毒症可继发 DIC,
