The Clinical Study Of The Treatment For Cough Variant Asthma Of Wind-heat Invading Lung By Chantui Powder

ObjectiveThrough observing the effects of using Chantui powder or pure western medicine for the treatment of CVA resulted from cough due to wind-heat invading lung, and by comparing their influence on the maximum peak expiratory flow of the pulmonary function indicator, to study the pathogenesis of CVA, as well as the effect mechanism of Chantui powder and its comprehensive advantage.MethodsAccording to the diagnostic criterion associated with the western and traditional Chinese medicine60cases have been randomly separated them into2equal groups (30/30). One is treatment group, another one is control group. The treatment group received the Chinese medicine therapy of Chantui powder for one month, while the control one was treated by the Procaterol hydrochloride two weeks and the Loratadine a month.ResultThe cough symptom points before and after treatment of each group and the points of the Chinese medical symptoms are all of statistical significance (p<0.01), The cough symptom points of both groups and the Chinese medical symptoms after treatment are all reduced significantly. After2week’s treatment, the cough symptom points of the2groups and the comparisons of the differences are of statistical significance (p<0.05). The reduction of the points of cough symptoms of the control group is apparently faster, but there is no significant differences after four weeks the medication was over. From the comparison of the different points on the Chinese medical symptoms, the reduction on the treatment group is more obvious than the control group. Moreover, the percentage of the results of the significant efficiency in comprehensive curative effect were83.33%vs36.67%has significant difference(treatment group vs control group, p=0.00). And the rate of the changing in PEF has also significant difference, there is obvious difference between the2groups before and after the treatment (p<0.01). Comparing the reduction of the variation rate, the treatment group is more obvious than the control group. Furthermore, the recrudescence of eight weeks that is four week after the medication was6vs17(relapse cases, treatment group vs control group; since the rate was30%vs70%, p=0.02). In addition, there was no adverse drug reactions in the treatment group while some of the control group occurred, such as the gastrointestinal adverse reactions, headache and dizziness.ConclusionThe result proves that the Chan Tui San has good effect on the treatment of CVA, it reduces the recurrent rates after treatment, and it reduces the side effects and risks which may be caused by the western medicine. It is worth using it widely in the clinical practice.
