OBJECTIVETo observe the difference in the clinical therapeutic effects on bronchial asthma in children of different body constitutions treated with sanfu pingchuan plaster and sanjiu zhichuan plaster.METHODSOne hundred and twenty-two children of bronchial asthma were divided into three groups according to TCM body constitutions, 42 cases in the qi deficiency constitution group, 40 cases in the yang deficiency constitution group and 40 cases in the phlegm damp constitution group. From 2011 to 2013, the acupoint plaster was applied to all of the children in the three groups during the dog days and the third nine-day period after the winter solstice each year. The average attack frequency and onset days of bronchial asthma and relevant immune function indicators were observed during treatment and 1 year after treatment in the children and the therapeutic effects were evaluated.RESULTS①In 2014, the acute attacks of bronchial asthma were (1.2±0.9) times and (1.4±0.4) times in the qi deficiency constitution group and the yang deficiency constitution group, all lower than (3.0±0.5) times in the phlegm damp constitution group (both P<0.05) separately. ②After treatment, in the qi deficiency constitution group and yang deficiency constitution group, the values of IgG, IgA and IgM were all increased as compared with those before treatment (all P<0.05). ③The total effective rate was over 95% in the children of the three groups. The clinical control rates in the qi deficiency constitution group and the yang deficiency constitution group were higher apparently than that in the phlegm damp constitution group, indicating the significant difference statistically (both P<0.05).CONCLUSIONSThe combined treatment of sanfu pingchuan plaster and sanjiu zhichuan plaster are effective on bronchial asthma in the children of different body constitutions. The therapeutic effects for the qi deficiency constitution and the yang deficiency constitution are more apparent than that for the phlegm damp constitution.
