OBJECTIVE： To investigate the improvement effects of andrographolide dripping pills combined with Danxi yupingfeng 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； observation 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 before 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）. Two 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 levels 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 observation 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.
