OBJECTIVE:To investigate the improvement effects of andrographolide dripping pills combined with Danxi yup-ingfeng granules on immunologic function of children with allergic rhinitis(AR). METHODS:Two hundred and eight AR children were randomly divided into control group,observation groupⅠ,observation groupⅡ,observation groupⅢ,with 52 cases in each group. Control group was given Loratadine syrup 10 mL,qd;observation groupⅠwas given Danxi yupingfeng granules 15 g,bid+Andrographolide dripping pills 0.6 g,tid;observation groupⅡwas given constant dose of Andrographolide dripping pills;observa-tion groupⅢwas given constant dose of Danxi yupingfeng granules. Four groups were treated for 2 weeks. 2 weeks later,they were given Loratadine syrup orally if the symptom appeared again. The levels of IgE and Th1/Th2 were compared among 4 groups be-fore treatment,1,2 weeks after treatment,3 months after the end of treatment. The children receiving Loratadine syrup orally due to the recurrence of AR 3 months after the end of treatment were observed. RESULTS:Before treatment,there was no statistical significance in serum levels of IgE and Th1/Th2 among groups(P>0.05). One week after treatment,serum levels of IgE and Th1/Th2 were improved significantly,with statistical significance (P<0.05);but there was no statistical significance among 4 groups (P>0.05). 2 weeks after treatment,serum levels of IgE and Th1/Th2 were improved significantly,and the observation groups were significantly better than the control group,with statistical significance(P<0.05). Three months afterthe end of treatment,serum lev-els of IgE and Th1/Th2 in observation group were improved significantly and better than control group,with statistical significance (P<0.05);there was no statistical significance in control group,compared to before treatment(P>0.05). The recurrence rate of ob-servation groupⅠwas significantly lower than that of observation groupⅡ,observation group Ⅲ and control group,with statistical significance(P<0.05). No obvious ADR was found in 4 groups. CONCLUSIONS:Andrographolidume dripping pills combined with Danxi yupingfeng granules can effectively improve immunologic function of AR children and reduce recurrence rate with good safety.
