文献报导,呼吸窘迫综合征(ARDS)和败血症休克患者肿瘤坏死因子(TNF)水平增加,提示TNF 在急性肺损伤发病机理中起一定作用,为了进一步评价TNF 与ARDS和败血症的关系,测定了ARDS 患者血清和支气管肺泡灌洗液(BALF)中TNF 水平。研究对象分为三组:(1)ARDS 组22例,男12例,女10例,平均年龄44±4岁。其中 It has been reported in the literature that the increased levels of tumor necrosis factor (TNF) in patients with respiratory distress syndrome (ARDS) and septic shock suggest that TNF plays a role in the pathogenesis of acute lung injury. In order to further evaluate the relationship between TNF and ARDS and sepsis, ARDS TNF levels in patient serum and bronchoalveolar lavage fluid (BALF). The subjects were divided into three groups: (1) 22 ARDS patients, 12 males and 10 females, with an average age of 44 ± 4 years. among them
