目的:研究T-bet、GATA-3、Foxm1在慢性鼻窦炎(CRS)黏膜组织中的表达及其与炎症分子表达的相关性.方法:选择2015年6月~2017年2月期间在胜利医院接受鼻内镜下手术的鼻窦炎患者和鼻中隔偏曲患者,分别作为CRS组和对照组.术中采集鼻黏膜组织,检测T-bet、GATA-3、Foxm1的mRNA表达量及炎症反应分子的蛋白表达量.结果:CRS组患者鼻黏膜组织中T-bet、GATA-3、Foxm1的mRNA表达量以及白介素(IL)-1β、γ干扰素(IFN-γ)、肿瘤坏死因子(TNF)-α、IL-4、IL-5、IL-19、IL-20R1、IL-20R2、基质金属蛋白酶(MMP)2、MMP9、PI3K、Akt、GSK-3β、p38MAPK的蛋白表达量均显著高于对照组;CRS患者鼻黏膜组织中T-bet、GATA-3、Foxm1的mRNA表达量与IL-1β、IFN-γ、TNF-α、IL-4、IL-5、IL-19、IL-20R1、IL-20R2、MMP2、MMP9、PI3K、Akt、GSK-3β、p38MAPK的蛋白表达量呈正相关关系.结论:慢性鼻窦炎黏膜组织中T-bet、GATA-3、Foxm1的高表达能够激活Th1、Th2免疫反应并引起黏膜炎症反应.%Objective: To study T-bet, GATA-3 and Foxm1 expression in chronic sinusitis mucosa and their correlation with inflammatory molecule expression.Methods: Patients with sinusitis and deflection of nasal septum who received nasal endoscopic surgery in Shengli Hospital between June 2015 and February 2017 were selected and enrolled in CRS group and control group respectively.Nasal mucosa tissue was collected during operation to determine mRNA expression of T-bet, GATA-3 and Foxm1 as well as protein expression of inflammatory molecules.Results: T-bet, GATA-3 and Foxm1 mRNA expression as well as IL-1β, IFN-γ, TNF-α, IL-4, IL-5, IL-19, IL-20R1, IL-20R2, MMP2, MMP9, PI3K, Akt, GSK-3β and p38MAPK protein expression in nasal mucosa tissue of CRS group were significantly higher than those of control group(P<0.05);T-bet, GATA-3 and Foxm1 mRNA expression in nasal mucosa tissue of patients with CRS were positively correlated with IL-1β, IFN-γ, TNF-α, IL-4, IL-5, IL-19, IL-20R1, IL-20R2, MMP2, MMP9, PI3K, Akt, GSK-3β and p38MAPK protein expression.Conclusions: High expression of T-bet, GATA-3 and Foxm1 in chronic sinusitis mucosa tissue can activate Th1 and Th2 immune response and cause mucosal inflammatory response.
