摘　　要：目的探讨血清肠型脂肪酸结合蛋白(I-FABP)对慢加急性肝衰竭(ACLF)发生发展的预测作用。方法回顾性分析2020年9月—2023年3月延边大学附属医院收治的168例肝硬化失代偿患者的临床资料,观察入院合并ACLF的患者情况和随访6个月新发ACLF事件。采用ELISA法测定患者入院血清I-FABP水平。非正态分布计量资料两组间比较采用MannWhitney U检验,多组间比较采用Kruskal-Wallis H秩和检验。计数资料组间比较采用χ^(2)检验。趋势性分析采用JonckheereTerpstra检验。采用Spearman相关分析两变量间相关性。多变量Cox回归法分析随访期间新发ACLF的影响因素。KaplanMeier曲线分析不同组间ACLF发生情况,并采用Log-rank检验评估差异。采用受试者工作特征曲线(ROC曲线)和曲线下面积评估I-FABP对ACLF发生、发展的预测性能。结果入组168例患者中43例合并ACLF,125例无ACLF的患者在随访期间新发ACLF19例。纳入时合并ACLF患者的I-FABP水平高于无ACLF者,差异有统计学意义(Z=4.359,P<0.001)。新发ACLF患者的I-FABP水平均高于未发生ACLF者,差异有统计学意义(Z=3.414,P<0.001)。I-FABP随ACLF分级增加而升高(H=17.385,P<0.001,P趋势<0.001)。多因素分析显示I-FABP与随访期间新发ACLF独立相关(HR=2.138,95%CI:1.297~3.525,P=0.003),且I-FABP三分位数显示出良好的区分能力(χ^(2)=12.16,P<0.001)。ROC曲线显示I-FABP对ACLF发生和发展具有较好的预测效能,ROC曲线下面积分别为0.854(95%CI:0.791~0.903)和0.747(95%CI:0.661~0.820),最佳截断值分别为2.07µg/L和1.86µg/L。结论I-FABP是预测ACLF发生和发展的生物标志物,有助于临床识别高危患者,改善临床管理。Objective To investigate the value of intestinal fatty acid binding protein(I-FABP)in predicting the development and progression of acute-on-chronic liver failure(ACLF).Methods A retrospective analysis was performed for the clinical data of 168 patients with decompensated liver cirrhosis who were admitted to The Affiliated Hospital of Yanbian University from September 2020 to March 2023.The conditions of the patients with ACLF on admission were observed,and the patients were followed up for 6 months to identify new-onset ACLF cases.ELISA was used to measure the serum level of I-FABP on admission.The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups,and the Kruskal-Wallis H rank sum test was used for comparison between multiple groups;the chi-square test was used for comparison of categorical data between groups;the Jonckheere-Terpstra test was used for trend analysis.The Spearman correlation analysis was used to investigate the correlation between two variables,and the multivariate Cox regression analysis was used to investigate the influencing factors for new-onset ACLF during follow-up.The Kaplan-Meier curve was used to analyze the onset of ACLF in different groups,and the log-rank test was used for the analysis of such differences.The receiver operating characteristic(ROC)curve and the area under the ROC curve(AUC)were used to investigate the performance of I-FABP in predicting the development and progression of ACLF.Results Among the 168 patients enrolled in this study,there were 43 patients with ACLF and 125 patients without ACLF,among whom 19 developed ACLF during follow-up.The patients with ACLF on admission had a significantly higher level of I-FABP than those without ACLF(Z=4.359,P<0.001).The patients with new-onset ACLF had a significantly higher level of I-FABP than those without new-onset ACLF(Z=3.414,P<0.001).The level of I-FABP increased with the increase in ACLF severity grade(H=17.385,P<0.001,Ptrend<0.001).The multivariate Cox regression ana
