Objective To explore the value of serum long non-coding RNA KCNQl opioid strand transcript 1(lncRNA KCNQ1OT1)and fibroblast growth factor 2(FGF2)in the evaluation of the condition and control level of pediatric bronchial asthma.Methods 96 children with bronchial asthma(Asthma group)and 76 healthy children(Control group)admitted to Yulin Hospital of Traditional Chinese Medicine from March 2021 to March 2023 were selected.According to the severity of bronchial asthma,the children were divided into a mild group(n=54)and a severe group(n=42).According to the disease control status after treatment,the children were divided into an asthma Control group(n=61)and an uncontrolled Asthma group(n=35).The serum levels of lncRNA KCNQ1OT1 and FGF2 were detected in each group.Multivariate Logistic regression analysis was performed to identify the factors affecting bronchial asthma disease control.The performance of lncRNA KCNQ1OT1 and FGF2 in predicting the control of bronchial asthma disease was evaluated using the receiver operating characteristic curve.Results The serum levels of lncRNA KCNQ1OT1(2.35±0.71)and FGF2(27.35±6.29 pg/ml)in the Asthma group were higher than those in the Control group(1.51±0.33,15.32±4.08 pg/ml),and the differences were statistically significant(t=9.527,14.437,all P<0.001).The serum levels of lncRNA KCNQ1OT1(2.59±0.35)and FGF2(28.65±1.03 pg/ml)in the severe group were higher than those in the mild group(2.16±0.41,26.34±1.24 pg/ml),and the differences were statistically significant(t=5.429,9.737,all P<0.001).The serum levels of lncRNA KCNQ1OT1(2.63±0.27)and FGF2(29.02±1.41 pg/ml)in the uncontrolled asthma group were higher than those in the controlled asthma group(2.19±0.35,26.39±1.52 pg/ml),and the differences were statistically significant(t=5.417,8.374,all P<0.001).High lncRNA KCNQ1OT1 and FGF2 levels were risk factors for uncontrolled disease in children with bronchial asthma(all P<0.05).The AUC of lncRNA KCNQ1OT1 and FGF2 combined to predict uncontrolled disease in children with bronchial asthma,which was higher than of lncRNA KCNQ1OT1 and FGF2 alone,and the differences were statistically significant(Z=3.250,2.096,all P<0.05).Conclusion Serum lncRNA KCNQ1OT1 and FGF2 are both elevated in children with bronchial asthma,which is related to the worsening of bronchial asthma and uncontrolled disease.Combining lncRNA KCNQ1OT1 and FGF2 can predict the level of bronchial asthma disease control.
