Biological indexes: lung wet/ dry weight, the rate of neutrophils and protein content in the pulmonary alveolar lavage fluid, pulmonary vascular permeability and pulmonary alveolar permeability index were correspondingly significantly high. 肺湿重与干重比、肺泡灌洗液中中性粒细胞比例、蛋白含量及肺泡通透指数、肺毛细血管通透性均显著升高。
Apoptosis rate of alveolar type II epithelial cells is significantly positively related to alveolar lung leak index, and the concentration of IL-2 in BALF to apoptosis rate and alveolar leak index. 肺泡Ⅱ型上皮细胞凋亡率与肺通透指数显著相关,BALF中IL-2水平与肺通透指数、肺泡Ⅱ型上皮细胞凋亡率显著相关。
