Abstract:Objective To investigate the changes and clinical significance of KL-6 and Plasminogen activator inhibitor-1(PAI-1)in children with wheezing less than 5 years old.Methods A total of 198 children under 5 years of age with wheezing symptoms diagnosed and treated in our hospital from January 2015 to December 2016 were selected and randomly divided into API positive group(n=104)and API--negative group(n=94)according to API scoring criteria.Patients in the two groups were inhaled budesonide suspension and bricanyl at 1-4 weeks,and only treated with montelukast sodium orally at 4 weeks.the asthma symptom scores were recorded before treatment,4,8 and 12 weeks after treatment,and the expression levels of KL-6 and PAI-1 in blood were detected.Results There was no significant difference between KL-6 and PAI-1 in API negative group(P>0.05).The expression of KL-6 and PAI-1 in API-positive group decreased with the treatment time(P<0.05),and the expression of KL-6 and PAI-1 in API-positive group was significantly higher than that in API-negative group(P<0.05).There was no significant difference in KL-6 and PAI-1 expression between the two groups at 12 weeks after treatment(P>0.05).There was no significant difference in asthma symptom score between the two groups before treatment(P>0.05).The symptom scores of asthma decreased significantly at 4,8 and 12 weeks after treatment,the difference was statistically significant(P<0.05).The scores of asthma symptoms in API positive group were significantly lower than those in API negative group at 4 and 8 weeks after treatment,the difference was statistically significant(P<0.05);there was no significant difference in the scores of asthma symptoms between the two groups at 12 weeks after treatment(P>0.05).Conclusion The expression of KL-6 and PAI-1 in the asthmatic children less than 5 years old is in a dynamic state and associates with the symptom score of asthma.
