Abstract:
Objective To investigate the key targets and pathways of Juhongtai formula granules in improving acute lung injury(ALI).Methods Juhongtai formula granules and their drug-containing serum components were analyzed by UPLC-QTOF-MS/MS,and the active ingredients were screened based on the"Lipinski Rule of Five".The action targets of the above active ingredients were obtained through the TCMSP,Swiss Target Prediction and SuperPred databases,and the ALI-related targets were obtained from the GeneCards,OMIM,PharmGKB,CTD databases and GEO chip.The target protein-protein interaction network was constructed using the String database and Cytoscape to analyze the key targets.The DAVID database was used for GO functional annotation and KEGG pathway enrichment analysis,and the CB-dock2 platform was used for molecular docking verification.After one week of adaptive feeding,the experimental SD rats were randomly divided into the blank group,the model group,the positive control group,the negative control group and the Juhongtai formula granules group,with 6 rats in each group.The rat model of ALI was replicated by tracheal infusion of lipopolysaccharide.The pathological morphology of lung tissues in each group of rats was observed by HE staining,and the mRNA expressions of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-1 β(IL-1β)and nitric oxide were detected by reverse transcription quantitative polymerase chain reaction(RT-qPCR).Results In total,44 components of the Juhongtai formula granules were identified,including 26 drug-containing serum components,and 21 key compounds were screened.A total of 22 intersection targets were obtained.The pathway enrichment results indicated the action of these targets on the advanced glycation end product receptor(AGE-RAGE)and TNF signaling pathways.The docking results showed that limonin,kaempferol and naringenin could be matched with prostaglandin peroxidase 2,nitric oxide synthase 2 and TNF.Animal experiments confirmed that the Juhongtai formula granules can alleviate inflammatory infiltration in lung tissue and reduce the expressions of TNF-α,IL6,IL-1β mRNA and nitric oxide.Conclusion Juhongtai formula granules can inhibit ALI-related inflammatory targets through the synergistic effects of multiple components such as limonin and kaempferol,regulate signaling pathways such as AGE-RAGE and TNF,reduce the production of inflammatory factors and nitric oxide,and improve ALI.
