Moreover, Fu et al. reported in 2012 that Moutan Cortex decreased the levels of cytokines such as IL-1β, IL-6, IL-10, and CXCL2 in the bronchoalveolar lavage fluid of rats with LPS-induced ALI and improved leukocyte infiltration in the alveolar space [4]. This evidence concerns the gene CXCL2 and acute respiratory distress syndrome.
