Objective: To explore the effect of beclometasone dipropionate combined with montelukast sodium in children's cough variation asthma and its affection on levels of eotaxin expression and pulmonary function. Methods: 82 children with cough variant asthma treated in our hospital from January 2014 to January 2016 as research objects, and were randomly divided into control group and research group(41 cases in each group). The children in the control group was treated with beclomethasone dipropionate, and the children in the research group was treated with montelukast sodium based on the control group.The children in the two groups were treated continuously for 3 months.The total effective rate and adverse reaction rate were compared between the two groups. The levels of serum interleukin(interleukin-5,interleukin-8 and interleukin-10), levels of immunoglobulin E, tumor necrosis factor alpha,pulmonary function[maximal mid-expiratory flow (MMEF) curve, forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)], peripheral eosinophils and eotaxin were compared between the two groups before and after treatment. Results: The total effective rate of the control group was 70.73%, which was significantly lower than that in the research group(92.68%),the difference had statistical meaning between the two groups(P<0.05).After treatment,the values of FEV1,FVC and MMEF in the control group were significantly lower than those in the research group, two sets of data had statistically significant differences(P<0. 05).After treatment, the levels of serum interleukin(interleukin-5,interleukin-8 and interleukin-10),immunoglobulin E and tumor necrosis factor alpha in the research group were significantly lower than those in the control group, the differences had statistical meanings between the two groups(P<0.05).After treatment, the peripheral eosinophils value and levels of eotaxin expression in the research group were significantly lower than those in the control group(P<0.05).The adverse reaction rate in the two groups were 19.51% and 9.76% respectively, the difference was not statistically significant(P>0.05).Conclusion: Beclometasone dipropionate combined with montelukast sodium has exact effect for children's cough variation, and it can decrease the level of airway inflammation, improve pulmonary function and inhibit eotaxin expression. |
