Objective To analyze the predictive value of changes in serum Notch1 and interferon γ-induced protein 10(IP-10)expression in children with bronchial asthma for airway remodeling.Methods A total of 120 children with bronchial asthma treated from August 2021 to December 2023 were selected and divided into the acute exacerbation group and the clinical remission group based on their disease status.Additionally,60 healthy children who underwent the physical examination during the same period were selected as the control group.The levels of Notch1 and IP-10 in the blood of the subjects were measured,and airway remodeling and pulmonary function indicators were assessed.Pearson correlation analysis was used to examine the correlation between serum IP-10,Notch1,and airway remodeling indicators.Receiver operating characteristic curve analy-sis was conducted to evaluate the predictive value of Notch1 and IP-10 for airway remodeling.Results There were statistically significant differences in the levels of Notch1 and IP-10 among the acute exacerbation group,clinical remission group,and control group,and the levels of Notch1 and IP-10 were highest in the acute exac-erbation group and lowest in the control group,with statistically significant differences(P＜0.05).The poste-rior and outer diameters of bronchial tubes ratio(T/D)and wall area percent(WA)levels in the acute exacer-bation group were obvious higher than those in the clinical remission group,and the differences were statisti-cally significant(P＜0.05).The forced expiratory volume in one second(FEV1)and FEV1/forced vital ca-pacity levels in the acute exacerbation group were lower than those in the clinical remission group,and the differences were statistically significant(P＜0.05).IP-10 and Notch1 were obvious positively correlated with airway remodeling indicators T/D and WA(P＜0.05).The area under the curve of IP-10 and Notch1 for pre-dicting airway remodeling in pediatric patients were both greater than 0.85,indicating high application value.Conclusion The levels of Notch1 and IP-10 increase during acute exacerbation of asthma and are closely relat-ed to airway remodeling and decreased lung function.Notch1 and IP-10 have high accuracy in predicting airway remodeling.
