Abstract:
Objective To analyze the relationship between serum long chain non coding ribonucleic acid(ln-cRNA)ANRIL,microRNA(miR)-423-5p and airway inflammation and remodeling in children with bronchial asthma and its predictive value.Methods A total of 98 children with bronchial asthma treated in Haikou Ma-ternal and Child Health Hospital from June 2020 to December 2022 were selected.46 children with acute at-tack were selected as the attack group and 52 children with clinical remission were selected as the remission group.Another 50 children who were healthy during physical examination in the same period were selected as the health group.The relative expression levels of serum lncRNA ANRIL and miR-423-5p were detected by real-time fluorescence quantitative polymerase chain reaction.The serum inflammatory factor indicators[in-terleukin-13(IL-13),transforming growth factor-β1(TGF-β1),vascular endothelial growth factor(VEGF)]were detected by enzyme-linked immunosorbent assay.Airway remodeling indicators[bronchial thickness(T/D),pipe wall area/total cross-sectional area of gas pipeline(WA)]and lung function indicators[first second forced expiratory volume(FEV1),peak expiratory flow(PEF),maximum mid expiratory flow(MMEF)]were measured.The correlation between expression of serum lncRNA ANRIL,miR-423-5p and airway inflam-mation and remodeling indicators were analyzed by the Pearson method.The predictive value of serum ln-cRNA ANRIL and miR-423-5p in the diagnosis of bronchial asthma was analyzed by receiver operating charac-teristic(ROC)curve.Results The relative expression level of serum lncRNA ANRIL in remission and attack groups was higher than that in healthy group,and the relative expression level of serum miR-423-5p was lower than that in healthy group,with statistical significance(P＜0.05).The relative expression level of serum ln-cRNA ANRIL in the attack group was higher than that in the remission group,and the relative expression lev-el of serum miR-423-5p was lower than that in the remission group,with statistical significance(P＜0.05).The levels of serum VEGF,IL-13 and TGF-β1 in attack and remission groups were higher than those in healthy group,and the difference was statistically significant(P＜0.05).The levels of serum VEGF,IL-13 and TGF-β1 in attack group were higher than those in remission group,and the difference was statistically sig-nificant(P＜0.05).The levels of T/D and WA in the remission and attack groups were higher than those in the healthy group,and the levels of FEV,,PEF and MMEF were lower than those in the healthy group,with statistical significance(P＜0.05).The levels of T/D and WA in the attack group were higher than those in the remission group,and the levels of FEV1,PEF and MMEF were lower than those in the remission group,with statistical significance(P＜0.05).The results of Pearson correlation analysis showed that serum ln-cRNA ANRIL expression was positively correlated with airway inflammation and remodeling indicators,and negatively correlated with lung function indicators(P＜0.05).The expression of miR-423-5p was negatively correlated with airway inflammation and remodeling indexes,and positively correlated with lung function inde-xes(P＜0.05).ROC curve analysis showed that the area under the curve of lncRNA ANRIL and miR-423-5p alone and combined detection were 0.772,0.707 and 0.865 respectively,the predictive value of combined de-tection in diagnosing bronchial asthma was higher.Conclusion The relative expression level of serum lncRNA ANRIL increase in children with bronchial asthma,and miR-423-5p decrease,which promote airway inflamma-tion,remodeling,lung function decrease,and which has high diagnostic efficacy for children with bronchial asthma.
