认为哮喘是外因作用于内因的结果 ,痰瘀伏肺为其宿根 ,外邪引触伏痰、痰瘀胶结、阻塞气道、痰阻气逆为其病机 ,寒热夹杂为其病性。具有宣肺化痰、降气平喘、清热活血功效的中药平喘合剂可明显改善哮喘发作期患儿的肺通气功能 ,明显降低患儿血浆中sICAM 1、IgE水平 ,与对照组比较有显著性差异 (P <0 .0 1,P <0 .0 5 ) ,推测其作用机制可能与减轻气道阻塞、调节免疫反应及抑制气道炎症等多个环节有关
It is believed that asthma is the result of external factors acting on the internal cause. Phlegm-stasis volvulus is its pest root. Exogenous evils trigger phlegm, phlegm and blood stasis cease, airway obstruction, phlegm obstruction is its pathogenesis, cold and heat inclusion is its pathogenicity. The traditional Chinese medicine Pingchuan Mixture, which has the functions of dispersing lung and resolving phlegm, lowering blood pressure and relieving asthma and expelling heat and promoting blood circulation, can obviously improve pulmonary aeration function in children with asthma attack and obviously reduce the plasma sICAM 1 and IgE levels in children with significant difference compared with the control group (P <0.01, P <0.05), suggesting that its mechanism of action may be related to reducing airway obstruction, regulating immune response and inhibiting airway inflammation and many other aspects
