表皮生长因子受体抑制剂对外源锌离子致大鼠急性呼吸道炎症的影响 [PDF]
目的:探讨表皮生长因子受体(EGFR)抑制剂对外源锌离子致大鼠呼吸道急性炎症的影响。方法:将100μmol/L硫酸锌溶液经气管灌注大鼠肺部复制动物炎症模型,于灌注后4h、8h和24h处死大鼠,以PBS为对照,分别测定支气管肺泡灌洗液(BALF)中白细胞计数、总蛋白、白细胞介素8(IL-8)以及乳酸脱氢酶(LDH)的含量,以选择炎症最明显的时间点。进一步用二甲基亚砜(DMSO)和EGFR抑制剂PD153035预灌注大鼠,观察其对硫酸锌溶液所致呼吸道炎症的影响。结果:不同灌注液作用后大鼠白细胞计数(F=12.

Clinical analysis of 103 cases of invasive pulmonary fungal infection [PDF]
目的 分析侵袭性肺部真菌感染(IPFI)的临床特点,探讨防治对策。方法 对103例IPFI的临床资料进行回顾性分析。结果 IPFI以COPD、支气管肺癌多见,滥用抗生素等是主要危险因素;念珠菌属占57.3%,其次为曲霉菌属占32.0%;病死率为20.4%。结论 IPFI是在多种诱发因素下继发的肺部感染,原发性IPFI少见;其病死率高,重视易患因素的控制、尽早诊断,综合治疗可降低死亡率。Objective: To analyze the clinical features of invasive ...

儿童下气道菌群多样性及其对支气管哮喘辅助性T细胞分化机制影响研究进展 [PDF]
哮喘是由多种细胞(如嗜酸性粒细胞、肥大细胞、T淋巴细胞、中性粒细胞、气道上皮细胞等)和细胞组分参与的以慢性气道炎症和气道高反应性为特征的一种异质性疾病[1]。近年来哮喘发病率逐年攀升,据全球哮喘防治创议(GINA)委员会调查显示,全球约有3亿人受到哮喘困扰[2],世界卫生组织(WHO)预计至2025年全世界哮喘患者将会增至4亿人。研究发现,哮喘患者气道菌群在丰度及多样性等方面与正常人存在显著差异[3 ...
