The effects of PM on LPS-induced ALI inflammation. A. The levels of IL-1β, IL-6, and TNF-α in BALF were determined by ELISA. B. The levels of inflammatory proteins in lung tissues was determined by Western blot analysis. C. The levels of HMGB1 protein in lung tissues was determined by Western blot analysis. The statistical results are presented as mean ± standard deviation (x±s, n=10 in each group). Compared with control group, ***P < 0.001; compared with LPS group, #P < 0.05, ##P < 0.01, ###P < 0.001. BALF: bronchoalveolar lavage fluid.
