摘要: 目的 通过检测脐血Toll样受体4(TLR4)、巨噬细胞迁移抑制因子(MIF)、白细胞介素-1β(IL-1β)水平,旨在分析三者与新生儿呼吸窘迫综合征(NRDS)患儿预后的关系。方法 选取2023年1月至2024年6月期间206例早产儿作为研究对象,依据NRDS诊断标准分为NRDS组(n=120)和非NRDS组(n=86),根据NRDS患儿预后情况分为良好预后组(n=90)、不良预后组(n=30)。采用ELISA检测脐血TLR4、IL-1β、MIF表达水平。多因素Logistic回归分析影响NRDS患儿预后不良的因素,受试者工作特征(ROC)曲线分析脐血TLR4、MIF、IL-1β在预测NRDS患儿不良预后的效能。结果 相较于非NRDS组,NRDS组脐血TLR4、MIF、IL-1β水平均明显升高(P<0.05);相较于良好预后组,不良预后组脐血TLR4、MIF、IL-1β水平明显升高(P<0.05);脐血TLR4、MIF、IL-1β水平升高均是影响NRDS患儿预后不良的危险因素(P<0.05);脐血TLR4、MIF、IL-1β及三者联合预测NRDS患儿预后的AUC分别为0.843、0.845、0.850、0.976,三者联合预测效能显著优于单一指标(Z三者联合-TLR4=3.841、Z三者联合-MIF=3.615、Z三者联合-IL-1β=2.452,P<0.001、0.001、0.05)。结论 NRDS患儿脐血TLR4、MIF、IL-1β水平均显著升高,三者水平变化与NRDS患儿预后密切相关,且三者联合在预测NRDS患儿不良预后方面展现出更高的效能。

Abstract: Objective To detect the expression level of Toll-like receptor 4 (TLR4), macrophage migration inhibitory factor (MIF) and interleukin-1β (IL-1β) in umbilical cord blood, and to analyze their relationship with the prognosis of neonatal respiratory distress syndrome (NRDS). Methods From January 2023 to June 2024, 206 premature infants in our hospital were reviewed. Complying with the NRDS diagnostic criteria, they were assigned into NRDS group (n=120) and non-NRDS group (n=86). Complying with the prognosis of NRDS patients, they were assigned into a good prognosis group (n=90) and a poor prognosis group (n=30). ELISA method was applied to detect the expression levels of TLR4, IL-1β, and MIF in umbilical cord blood. Multivariate Logistic regression was applied to analyze the factors affecting the prognosis of NRDS. Receiver operating characteristic (ROC) curve was applied to analyze the efficacy of cord blood TLR4, MIF, and IL-1β in predicting poor prognosis in children with NRDS. Results Compared with the non-NRDS group, the level of TLR4, MIF and IL-1β in umbilical cord blood were significantly higher in the NRDS group (P<0.05). Compared with the good prognosis group, the levels of TLR4, MIF and IL-1β in umbilical cord blood were greatly higher in the poor prognosis group (P<0.05). Elevated levels of TLR4, MIF, and IL-1β in umbilical cord blood was a group of risk factors affecting for poor prognosis in children with NRDS (P<0.05). The AUC of TLR4, MIF, IL-1β, and their combination in predicting the prognosis of NRDS children in umbilical cord blood was 0.843, 0.845, 0.850, and 0.976, respectively. The effectiveness of the combined prediction of the three indicators was greatly better than that of a single indicator (Zcombination-TLR4=3.841,Zcombination-MIF=3.615, Zcombination-IL-1β=2.452, P<0.001, 0.001, 0.05). Conclusions The level of TLR4, MIF, and IL-1β in umbilical cord blood of children with NRDS is greatly elevated. The changes in their level of these factors are closely related to the prognosis of NRDS children. The combination of the three shows higher efficacy in predicting poor prognosis in NRDS children.
