Περίληψη: Acute lung injury (ALI) is a severe respiratory syndrome for which there is still a lack of effective treatment. Salvianolic acid A (Sal A) is a bioactive polyphenol extracted from Salvia miltiorrhiza Bunge, which has anti-inflammatory and antioxidant effects, but its role in ALI is unclear. We injected 50 µL LPS into the trachea of mice, and treated MLE-12 cells with 1 µg/mL LPS to construct ALI mouse and cell model. The levels of genes and proteins was identified using RT‒qPCR, western blot and immunofluorescence. The damage of MLE-12 cells and mouse lung tissue was evaluated by CCK-8, ELISA, TUNEL and HE staining. Sal A treatment can significantly inhibit LPS-induced inflammation and apoptosis, and then inhibit MLE-12 cell damage and ALI progression. From a mechanistic standpoint, Sal A promotes the expression of LC3 II/I and Beclin1, suppresses p62 expression, increases cell autophagy, and suppresses LPS-induced inflammatory cytokines IL-6, IL-1β, and TNF-α expression, ultimately reducing LPS-induced inflammation in lung epithelial cells and alleviating ALI progression. The main function of Sal A is to achieve this by inhibiting the expression of miR-217-5p and thereby promoting the expression of FOXO1. Our research results may provide a new target for the treatment of ALI with Sal A.
