%X 目的：观察全真一气汤对慢性阻塞性肺疾病(COPD)大鼠肺组织LASP1和CXCR1表达的影响，探析全真一气汤对COPD的炎症反应和免疫功能的影响。方法：将18只SD大鼠随机分为中药组和模型组，每组各9只。利用烟熏联合内毒素脂多糖(LPS)构建COPD大鼠模型。模型组每日予0.9%生理盐水灌胃；中药组每日予40%全真一气汤浓缩汤剂灌胃。利用PCR技术检测大鼠肺组织LASP1和CXCR1mRNA水平的变化，Western blot检测大鼠肺组织LASP1和CXCR1蛋白水平的变化。结果：中药组LASP1 mRNA表达丰度为模型组的0.145倍；中药组CXCR1 mRNA表达丰度为模型组的0.614倍。与模型组相比，中药组LASP1、CXCR1蛋白表达水平均显著降低。结论：全真一气汤能通过下调LASP1和CXCR1基因及蛋白的表达，改善COPD大鼠炎症微环境，这可能是其降低COPD引起肺癌发生风险的潜在机制之一。<br />
Objective: To observe the effects of Quanzhen Yiqi Decoction on the expression of LASP1 and CXCR1 in lung tissue of chronic obstructive pulmonary disease (COPD) rats, and to explore the effects of Quanzhen Yiqi Decoction on inflammation and immune function of COPD. Methods: Eighteen SD rats were randomly divided into Chinese medicine group and model group, with 9 rats in each group. COPD rat model was established by smoking combined with lipopolysaccharide (LPS). The model group was given 0.9% normal saline daily. The traditional Chinese medicine group was given 40% Quanzhen Yiqi Decoction concentrated decoction every day. The mrna levels of LASP1 and CXCR1 in rat lung tissue were detected by fluorescence quantitative PCR, and the protein levels of LASP1 and CXCr1 in rat lung tissue were detected by Western blot. Results: The mRNA expression abundance of LASP1 in the Chinese medicine group was 0.145 times that in the model group. The mRNA expression abundance of CXCR1 in the TCM group was 0.614 times of that in the model group. Compared with model group, the protein expression levels of LASP1 and CXCR1 in TCM group were significantly decreased. Conclusions: Quanzhen Yiqi Decoction can inhibit airway inflammation in COPD rats by down-regulating the expressions of LASP1 and CXCR1 genes and proteins, which may be one of the potential mechanisms to reduce the risk of lung cancer caused by COPD.
