Effects of PM2.5 on Naive T Cell Differentiation in Asthma [PDF]

open access: yes, 2017
支气管哮喘(asthma),简称哮喘,是一种以气道高反应性和可逆性气道阻塞为特点的慢性炎症性疾病。虽然对哮喘发病机制和治疗的研究取得了很大进展,但全世界哮喘发病率和死亡率仍呈现上升趋势。哮喘的发病危险因素包括遗传因素(内因)和环境因素(外因)两个方面。环境因素作为诱发哮喘和哮喘急性发作的重要危险因素,主要包括过敏原、气候变化和空气污染等。PM2.5致病的主要原因是由于细颗粒物粒径小,比表面积大,活性强,容易吸附空气中的各类有毒成分。我们前期研究发现PM2.5 ...

支气管哮喘患者诱导痰炎性细胞中Tim-3 mRNA的表达及作用机制研究

open access: yesZhongguo shiyan zhenduanxue, 2015
目的探讨支气管哮喘患者诱导痰炎性细胞中Tim-3mRNA的表达及作用机制,并分析其与上清液中IL-4、IFN-γ和肺功能指标的相关性。方法将2012年5月-2013年8月我院收治的支气管哮喘患者分为哮喘缓解组和哮喘发作组,并于同期随机选取120例健康体检者为对照组,通过逆转录-聚合酶链反应技术(RT-PCR)检测三组的诱导痰炎性细胞中Tim-3mRNA的水平,同时采用酶联免疫吸附法(ELISA)检测上清液中IL-4、IFN-γ,分析其与Tim-3mRNA的相关性。结果哮喘发作组、哮喘缓解组FEV1 ...
