摘　　要：目的探讨血清学生物标志物对急性呼吸窘迫综合征(ARDS)早期诊断预警及预后判断的预测效果。方法采用多中心、前瞻队列研究的方法,从2014年1月开始纳入各中心收治的ARDS与ARDS高危病例。采集患者的人口学资料,检测患者在入组24 h内的血清学指标(sRAGE、CC16、Ang-2、sICAM-1、PAI-1、Su PAR、HMGB1)。采用Logistic回归分析对影响高危ARDS患者发展成为ARDS危险因素和影响ARDS预后的危险因素。用ROC曲线比较单个危险因素或联合多个危险因素对ARDS发生的预警及ARDS死亡预后的预测效果,计算其预测的灵敏度、特异度及约登指数。结果共纳入ARDS患者59例,ARDS高危患者41例。ARDS发生的独立危险因素有HMGB1、sICAM-1、Ang-2、CC16、PAI-1。其中HMGB1预测效果最好(AUC=0.908),其次根据AUC大小顺序为CC16(AUC=0.861),Ang-2(AUC=0.858),PAI-1(AUC=0.801),sICAM-1(AUC=0.773)。单指标分析中,敏感度最高的单指标为HMGB1与sICAM-1,皆为79.7%,特异度最高的指标为HMGB1、CC16与Ang-2,皆为87.8%。在联合预测中,HMGB1与Ang-2联合预测,特异度最高,为95.1%,其AUC也为最高(0.92)。HMGB1、Ang-2与PAI-1指标联合预测,敏感度最高,为89.9%。多指标联合预测,可以在一定程度上提高对ARDS诊断预测的灵敏度和特异度。对ARDS预后分析,sRAGE与Ang-2是其死亡的独立危险因素。sRAGE(AUC=0.791)比Ang-2(AUC=0.67)对ARDS患者死亡预测效果好。两指标联合可以提高ARDS死亡预测的特异性。结论在ARDS高危患者中,HMGB1、sICAM-1、Ang-2、CC16、PAI-1是其发展成为ARDS的独立危险因素。HMGB1与Ang-2联合预测有较好的特异性,HMGB1、Ang-2与PAI-1联合预测有较好的敏感性。对于ARDS患者,sRAGE与Ang-2的增高预示着ARDS患者预后不良,两者联合预测可以提高预测的特异性。Objective To investigate the predictive effect of serological biomarkers in early diagnosis and prognosis of acute respiratory distress syndrome （ARDS）. Methods A multieenter, prospective cohort study was conducted from January 2014 to enroll ARDS cases and cases at high risk of ARDS in each center. The patients＇ demographic data were collected and the serological biomarkers, including soluble receptor of advanced glycosylation end products （sRAGE）, Clara cell protein （CC16）, angiopoietin-2 （Ang-2）, soluble intercellular adhesion molecule 1 （sICAM-1）, plasminogen activator inhibitor-1 （PAI-1）, soluble urokinaseplasminogen activator receptor （ sUPAR）, and high-mobility group box-1 （ HMGB1 ） were tested within 24 h after admission. Logistic regression analysis was used to recognize the risk factors for accelerating the progress of the patients at high risk to ARDS and the factors influencing the prognosis of ARDS. Receiver operating characteristic （ROC） curve was used to compare the predictive effects of single factor or combination of multiple factors in early warning and outcome of ARDS for the sensitivity, specificity and Youden index. Results A total of 59 ARDS patients and 41 patients at high risk of ARDS were enrolled in this study. The independent risk factors for ARDS were HMGB1, sICAM-I, Ang-2, CC16 and PAI-1, and HMGB1 showed the best predictive effect with area under curve （ AUC ） of 0. 908, followed by CC16 （ 0. 861 ）, Ang-2 （0. 858）, PAI-1 （0. 801）, and sICAM-1 （0. 773）. In the single index analysis, the most sensitive indexes were HMGB1 and sICAM-1, both with the sensitivity of 79.7%, and the highest specific indexes were HMGB1, CC16 and Ang-2, all with the specificity of 87.8%. In the combined prediction, HMGB1 combined with Ang-2 had the highest specificity of 95.1% and the highest AUC of 0.92. The sensitivity of combining HMGB-1, Ang-2 and PAI-1 （89.9%） was the highest to predict. Multi-index combined prediction, to a certain extent, imp
