The simultaneity use of Xiao Er Chuan Ke Ye and Cang Er Zi San intervening asthma and allergic rhinitis,comparing simply use Xiao Er Chuan Ke Ye,has the predominance in prolonging time of introducing asthma and reducing the frequency of nodding breathe,which indicated that the treatment of allergic rhinitis has great importance in asthma control and lessen the degree of asthma(frequency of rat nodding breath).3,The combination high-dose group has better therapeutic effect than dexamethasone group,all Chuan Ke Ye groups and combination low,medium group in the prevention and control of allergic rhinitis symptoms,reduced airway hyper responsiveness,while in improving breath difficulties combination high-dose group has similar effect with western medicine group,and better effect than all Chuan Ke Ye groups and combination low,medium group.Its efficacy increased with the prolonging of treatment time,but fewer side effects,which makes the application safer and more reliable.4,Xiao Er Chuan Ke Ye combining with Cang Er Zi San can obviously improve the pathological changes in rats with bronchial airway remodeling,reducing the serum TGF-β1,IL-4,ECP levels,increasing the level of serum IFN-γand the imbalance IFN-γ/ IL-4 ratio.

而运用小儿喘咳液合苍耳子散同时干预哮喘与过敏性鼻炎，较之单纯使用小儿喘咳液治疗哮喘，其在延长引喘时间、减少点头呼吸频度等方面有明显的优势，说明过敏性鼻炎的治疗，对于控制哮喘发生，减轻哮喘发作的程度，有着重要的意义。3、大剂量的合方在预防和控制过敏性鼻炎症状、降低哮喘气道高反应性方面疗效较地塞米松对照组、喘咳液各剂量组及合方小、中剂量组更优，而改善呼吸困难方面则与西药组相当，优于喘咳液各剂量组及合方小、中剂量组，且其疗效随着治疗时间的延长而增加，但副作用更少，使用更加安全可靠。4、小儿喘咳液合苍耳子散能明显改善气道重塑大鼠支气管的病理改变，同时降低血清TGF-β1、IL-4、ECP水平，提高血清IFN-γ水平及失衡的IFN-γ/IL-4比值。
