Abstract:Objective: To investigate the protective effects of curcumin on acute respiratory distress syndrome (ARDS) in mice by regulating the MAPK/NF-κB signaling pathway. Methods: BALB/C mice were randomly divided into five groups: control group, model group, curcumin group (200mg/kg), anisomycin group (MAPK activator, 20mg/kg), and curcumin (200mg/kg) + anisomycin (20mg/kg) group, with 12 mice per group. ARDS models were established in the model and drug intervention groups via intratracheal instillation of lipopolysaccharide (LPS), while the control group received an equal volume of normal saline. After 3 days of intervention, the following were measured: lung function indices-forced vital capacity (FVC), peak expiratory flow (PEF), and oxygenation index (OI); inflammatory cell count in bronchoalveolar lavage fluid (BALF); histopathological changes and lung injury scores in lung tissues via HE staining; levels of TNF-α, IL-1β, IL-10, and IL-13 in BALF and serum using ELISA; and MAPK/NF-κB pathway protein expression in lung tissues via Western blotting. Results: Compared with the control group, the model group showed significantly increased inflammatory cell count, lung injury score, TNF-α and IL-1β levels, and p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 ratios (P<0.05), while FVC, PEF, OI, IL-10, and IL-13 levels were significantly decreased (P<0.05). Compared with the model group, the curcumin group had reduced inflammatory cell count, lung injury score, TNF-α and IL-1β levels, and p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 ratios (P<0.05), along with increased FVC, PEF, OI, IL-10, and IL-13 levels (P<0.05). The anisomycin group, compared to the model group, exhibited further increases in inflammatory markers and reductions in lung function indices. Co-administration of curcumin and anisomycin negated the protective effects observed in the curcumin group alone. Conclusion: Curcumin inhibits the activation of the MAPK/NF-κB signaling pathway, reducing inflammation, mitigating lung tissue damage, and improving lung function in ARDS mice, thereby exerting a significant protective effect on the lungs.
