Study On The Relationship Between Etiology And TCM Syndrome Types Of Bronchiolitis In Children

1.Purpose:To study the correlation between etiology and TCM syndrome types of bronchiolitis in children,so as to provide objective basis for clinical syndrome differentiation.2.Methods:With the combination of retrospective study and prospective study,a questionnaire was used to collect the information of 301 children with bronchiolitis in the pediatric ward of Shandong Hospital of traditional Chinese Medicine from January 2015 to January 2020.SPASS23.0 was used to make statistics,and X2 was used to test the counting data,P < 0.05.There was statistical significance.The main analysis is as follows:(1)the distribution of syndrome types and pathogens of bronchiolitis;(2)the correlation between syndrome types and pathogens.And further expand the study of the distribution of each syndrome type in sex,course of disease,season,birth status,birth mode and feeding mode.3.Results:(1)in terms of syndrome type distribution,phlegm-heat closed lung syndrome was the most common in 91 cases(30.23%),followed by wind-heat closed lung syndrome in 73 cases(24.25%),wind-cold closed lung syndrome in 66 cases(21.93%),and other syndromes accounted for less than 20%.(2)in terms of pathogen distribution,the positive rate was69.10%,121 cases(40.2%)were single infection and 87 cases(28.9%)were mixed infection.The main pathogens of single infection were respiratory syncytial virus and parainfluenza virus Ⅲ,and the main pathogens of mixed infection were influenza virus A with parainfluenza virus Ⅰ and respiratory syncytial virus with influenza virus A.(3)the early syndrome types(wind-cold closed lung syndrome,wind-heat closed lung syndrome)and middle syndrome(phlegm-heat closed lung syndrome,damp-heat closed lung syndrome)were related to the types of positive pathogens as a whole.There were differences in the distribution of positive pathogens among wind-cold lung closure syndrome,wind-heat lung closure syndrome and damp-heat lung closure syndrome,but there was no difference in the distribution of positive pathogens among wind-cold lung closure syndrome,wind-heat lung closure syndrome and damp-heat lung closure syndrome.Respiratory syncytial virus was the most common pathogen in children with wind-cold closed lung syndrome,influenza virus A was the most common pathogen in children with wind-heat closed lung syndrome,and mycoplasma pneumoniae infection was more common in children with damp-heat closed lung syndrome.(4)in terms of sex,the ratio of male to female was 2.4.There were differences in the gender composition of phlegm-heat lung closure syndrome,wind-heat lung closure syndrome and wind-cold lung closure syndrome,and the proportion of males was more.(5)In the course of disease,wind-cold closed lung syndrome and wind-heat closed lung syndrome were mainly 1-3 days,phlegm-heat closed lung syndrome and damp-heat closed lung syndrome were mainly4-7 days.(6)in season,the distribution of each syndrome type is different in season,and most of them are in winter.(7)in the state of birth,full-term infants are more common in wind-cold lung closure syndrome,wind-heat lung closure syndrome,phlegm-heat lung closure syndrome and damp-heat lung closure syndrome.(8)in the way of birth,there is no difference in the distribution of syndrome types in the way of birth.(9)in terms of feeding patterns,the distribution of wind-cold closed lung syndrome,wind-heat closed lung syndrome,phlegm-heat closed lung syndrome and damp-heat closed lung syndrome were different,and breastfeeding was common.4.Conclusion:There is a certain correlation between the pathogen of bronchiolitis and TCM syndrome type.Respiratory syncytial virus was the most common pathogen in children with wind-cold closed lung syndrome,influenza virus A was more common in children with wind-heat closed lung syndrome,and mycoplasma pneumoniae infection was more common in children with damp-heat closed lung syndrome.
