目的 探讨麻黄汤对模型大鼠鼻黏膜屏障功能的影响及作用机制。方法 以冷-热循环刺激复制鼻黏膜免疫功能低下大鼠模型，并予麻黄汤灌胃，取鼻黏膜进行转录组学测序，并用qPCR和Western blot法验证结果。结果 给予模型大鼠麻黄汤后，可影响β-干扰素水平及细胞外基质、细胞因子应答等进程，并通过影响肿瘤坏死因子信号通路、JAK-STAT信号通路等发挥作用。麻黄汤通过激活IL-22/STAT3 通路上调LCN2、S100A8、MUC5b、MMP13、CXCL10、CCL20、IL17RA差异基因的表达及IL-22、STAT3、p-STAT3、p-STAT1 的蛋白表达，并降低TRAF6 的mRNA表达。结论 麻黄汤可通过IL-22/STAT3 信号通路提高模型大鼠鼻腔局部免疫屏障功能。
Effect of Mahuang Decoction on the Immune Barrier Function of Nasal Mucosa in Model Rats
Objective To investigate the effect of Mahuang Decoction on the nasal mucosal barrier function in model rats and relevant mechanism.Methods Rat models of nasal mucosal immune dysfunction were constructed by cold-hot cycle stimulation and were given Mahuang Decoction by gavage.The nasal mucosa was taken for transcriptome sequencing,and the qPCR and Western blot were used for verification test.Results Mahuang Decoction could affect the β-interferon level,extracellular matrix,response to cytokines and other processes in model rats,and it also played a role by affecting the tumor necrosis factor signaling pathway,JAK-STAT signaling pathway,etc.Mahuang Decoction upregulated the expression of differential genes including LCN2,S100A8,MUC5b,MMP13,CXCL10,CCL20,IL17RA and the protein expression of IL-22,STAT3,p-STAT3 and p-STAT1,and decreased the mRNA expression of TRAF6 by activating the IL-22/STAT3 pathway.Conclusion Mahuang Decoction can improve the local immune barrier function in the nasal cavity of model rats through the IL-22/STAT3 signaling pathway.
