The severity of cough before and after treatment and the curative effect in the two groups were compared. Results:After treatment,the scores of severity of cough and indexes of lung function in the two groups were improved(P<0.05). After treatment, the score of severity of cough and indexes of lung function in the observation group were better than those in the control group(P<0.05). After treatment,the neutrophils percentage in sputum and Th1/ Th2 ratio in the two groups were improved when compared with those before treatment(P<0.05), the difference being significant(P<0.05). There was no significant difference being found in the comparison of incidences of pharynx discomfort, vomiting,dizziness and rash between the two groups(P>0.05).
