Results The total effective rate of observation group was significantly higher than that of control group (P<0.05). After treatment, clinical symptoms disappear time of expectoration, wheezing and cough in the observation group was significantly shorter than that in the control group (P<0.05). After treatment, the levels of TNF-α, IL-6, CRP and IL-4 in two groups were significantly decreased (P<0.05), and the levels of TNF-α, IL-6, CRP and IL-4 in the observation group were significantly lower than those in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between two groups.
