摘　　要：目的探讨半乳糖凝集素-3(Galectin-3)、白细胞介素(IL)-1β、IL-9在难治性肺炎支原体肺炎(RMPP)患儿外周血中的表达情况及临床意义。方法选取确诊为RMPP的132例住院患儿为RMPP组,另取同期128例普通肺炎支原体肺炎(GMPP)患儿为GMPP组。收集患儿C反应蛋白(CRP)、肿瘤坏死因子-α(TNF-α)、降钙素原(PCT)等临床资料。采用酶联免疫吸附试验(ELISA)检测入组时Galectin-3、IL-1β、IL-9表达水平;采用Pearson或Spearman法分析RMPP患儿外周血Galectin-3、IL-1β、IL-9水平与临床因素的相关性;多因素Logistic回归分析GMPP进展为RMPP的危险因素;受试者工作特征(ROC)曲线分析外周血Galectin-3、IL-1β、IL-9水平对RMPP的预测价值。结果RMPP组热程、CRP、TNF-α、PCT、Galectin-3、IL-1β、IL-9、肺外并发症比例高于GMPP组(P<0.01)。相关性分析结果显示Galectin-3、IL-1β、IL-9水平与热程、肺外并发症、CRP、TNF-α、PCT均呈正相关(P<0.01)。Logistic回归分析结果显示,Galectin-3、IL-1β、IL-9升高是GMPP进展为RMPP的独立危险因素(P<0.05)。外周血Galectin-3、IL-1β、IL-9及三者联合预测GMPP进展为RMPP的曲线下面积(AUC)分别为0.852、0.813、0.812和0.949,联合预测效能最高(P<0.01)。结论RMPP患儿外周血Galectin-3、IL-1β、IL-9水平均异常升高,三者联合检测可作为评估GMPP进展为RMPP的重要指标。Objective To investigate the expression levels and clinical significance of Galectin-3,interleukin(IL)-1βand IL-9 in peripheral blood of children with refractory mycoplasma pneumoniae pneumonia(RMPP).Methods A total of 132 hospitalized children diagnosed with RMPP were selected as the RMPP group,and another 128 children with general MPP(GMPP)in the same period were selected as the GMPP group.The clinical data of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α)and procalcitonin(PCT)in pediatric patients were collected.The expression levels of Galectin-3,IL-1βand IL-9 were detected by enzyme-linked immunosorbent assay(ELISA).The correlation between Galectin-3,IL-1βand IL-9 levels in peripheral blood of RMPP children and clinical factors were analyzed by Pearson or Spearman methods.Multivariate Logistic regression analysis was used to analyze risk factors of GMPP progression to RMPP.The predictive value of peripheral blood Galectin-3,IL-1βand IL-9 levels to RMPP was analyzed by receiver operating characteristic(ROC)curve.Results The heat course,CRP,TNF-α,PCT,Galectin-3,IL-1β,IL-9 and the proportion of extrapulmonary complications were higher in the RMPP group than those in the GMPP group(P<0.01).The correlation analysis results showed that Galectin-3,IL-1βand IL-9 levels were positively correlated with heat course,extrapulmonary complications,CRP,TNF-αand PCT(P<0.01).Logistic regression analysis showed that the increased levels of Galectin-3,IL-1βand IL-9 were independent risk factors for GMPP progression to RMPP(P<0.05).The area under the curve(AUC)of peripheral blood Galectin-3,IL-1β,IL-9 and their combined prediction of GMPP progression to RMPP were 0.852,0.813,0.812 and 0.949,respectively,and the combined prediction showed the highest efficacy(P<0.01).Conclusion The levels of Galectin-3,IL-1βand IL-9 in the peripheral blood of children with RMPP are abnormally elevated,and their combined detection can be used as an important indicator for evaluating the progression of GMPP to RMPP.
