内质网应激与急性肺损伤恶化关联性的研究进展 [PDF]

open access: yesZhongshan Daxue xuebao. Yixue kexue ban
急性肺损伤(ALI)是一种严重威胁全球人类生命健康的疾病,其主要病理特征为肺泡上皮细胞和肺毛细血管内皮细胞的损伤,导致弥漫性肺间质水肿和肺泡水肿,通常伴有急性低氧性呼吸功能不全。内质网应激(ERS)在ALI的发生和发展过程中扮演着关键角色。它通过多种途径加剧急性肺损伤:在细胞凋亡方面,关键蛋白如GRP78、CHOP和caspase-12参与调控,促进肺血管内皮细胞和肺泡上皮细胞的凋亡,从而加重肺组织损伤;在ROS代谢方面,诱导活性氧(ROS)的大量释放,NADPH氧化酶等参与ROS的产生过程 ...

体外循环中低流量肺动脉灌注对肺功能的影响 [PDF]

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2006
【目的】探讨体外循环中低流量肺动脉灌注对肺功能影响的作用机理。【方法】体质量18-22kg的杂种犬10只,随机分为对照组(n=5)和肺灌注组(n=5)。常规建立体外循环。肺灌注组用氧合血30mL/(kg·min)灌注肺动脉。分别于转流前,停体外循环即刻,转流后1h,转流后2h采集数据,计算氧合指数、肺动态顺应性。检测肺静脉血丙二醛(MDA)、超氧化物歧化酶(SOD)、细胞间黏附分子1(ICAM-1)和P选择素。【结果】转流后肺灌注组犬的肺动态顺应性和氧合指数明显高于对照组(P〈0.05 ...
