Abstract:
Objective To investigate the regulatory effect of Mahuang Dingchuan Decoction on airway inflammation,airway remodeling and imbalance of helper T cell 1(Th1)/helper T cell 2(Th2)in children with allergic asthma.Methods A total of 126 children with allergic asthma of phlegm-heat obstructing the lung type at acute attack stage were randomly divided into observation group and control group,with 63 cases in each group.The control group was treated with conventional western medicine,and the observation group was treated with Mahuang Dingchuan Decoction on the basis of treatment for the control group.The total course of treatment for the two groups covered 14 days.Before and after treatment,the two groups were observed in the changes of lung function indicators of forced expiratory volume in one second(FEV1)and peak expiratory flow(PEF),airway inflammation indicators of neutrophil count,lymphocyte count,eosinophil count,monocyte percentage and levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in the sputum,airway remodeling indicators of airway wall area(WA),airway lumen area(LA)and airway total area(TA),and levels of Th1/Th2 cytokines of gamma-interferon(IFN-γ)and interleukin 4(IL-4).After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 14 days of treatment,the total effective rate of the observation group was 93.65％(59/63),and that of the control group was 80.95％(51/63).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the values of pulmonary function indicators of FEV1 and PEF in the two groups were significantly higher than those before treatment(P＜0.01),and the increase in the observation group was significantly superior to that in the control group(P＜0.05).(3)The analysis of airway inflammation indicators showed that the percentages of neutrophils,eosinophils and monocytes and the levels of IL-6 and TNF-α in the sputum of the two groups after treatment were significantly lower than those before treatment(P＜0.05),and the percentage of lymphocytes was significantly higher than that before treatment(P＜0.05).The decrease of the percentages of neutrophils,eosinophils and monocytes and the levels of IL-6 and TNF-α in the sputum as well as the increase of the percentage of lymphocytes in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the value of airway remodeling indicator of WA in the two groups was lower(P＜0.05)and the values of LA and TA were higher than those before treatment(P＜0.05).The decrease of WA value and the increase of LA and TA values in the observation group were significantly superior to those in the control group(P＜0.05).(5)The observation of Th1/Th2 cytokines showed that the serum IFN-γ level and IFN-γ/IL-4 ratio in the two groups after treatment were significantly higher than those before treatment(P＜0.05),and the serum IL-4 level was significantly lower than that before treatment(P＜0.05).The increase of serum IFN-γ level and IFN-γ/IL-4 ratio and the decrease of serum IL-4 level in the observation group were significantly superior to those in the control group(P＜0.05).(6)No serious adverse reactions were found in the two groups during the treatment,or no obvious abnormalities were found in the safety indicators such as electrocardiogram,blood routine test,liver function examination,heart rate and blood pressure.Conclusion Mahuang Dingchuan Decoction is beneficial to alleviating airway inflammation and airway remodeling in children with allergic asthma,regulating Th1/Th2 imbalance,and improving lung function in children,with definite effective and high safe.
