AIM:To study the protective effect of heat shock factor1(HSF1)on the mice with lipopolysaccharide(LPS)-induced acute lung injury(ALI),and to screen the relevant differentially-expressed genes.METHODS:ALI mouse model was established by LPS intracheal instillation.The macroscopic and pathological changes of the lung tissue were observed,and the concentrations of total protein,TNF-α,IL-β,IL-6 and VEGF in the bronchoalveolar lavage fluid(BALF)were analyzed.Differentially-expressed genes in the lung tissues of H...
