Ethnopharmacological Relevance:
Acute lung injury (ALI) is an aggressive inflammatory disease of the lungs characterized by a high mortality rate. More and more researchers have found that herbal medicines are highly effective in preventing and treating inflammatory lung diseases. Among them, Dachengqi Decoction (DCQD) is considered to be the representative prescription of "lung-intestine combined treatment" in traditional Chinese medicine, and its potential protective mechanism against ALI is worthy of further study.
Aim Of The Study:
Based on the theory of "lung-intestine combined treatment", the protective effect and molecular mechanism of DCQD in alleviating ALI were verified by network pharmacology and experiments.
Materials And Methods:
The active ingredients of DCQD were obtained by UPLC-MS. Network pharmacology and molecular docking techniques were used to screen the active ingredient-target pathway of DCQD for ALI treatment. Additionally, the ALI model was constructed and verified in vivo according to the predicted results.
Results:
34 active components and 570 potential targets of DCQD were selected by network pharmacological analysis. In addition, 950 target genes of ALI and 2095 target genes related to sepsis were obtained, and 570 interlinked target genes of the two were identified. We finally screened out 199 common target genes critical to DCQD treatment of ALI and sepsis, and then enriched them with GO and KEGG. In the ALI model, studies have found that DCQD alleviates the inflammatory response of ALI, possibly by inhibiting HIF-1α-mediated glycolysis.
Conclusion:
This study confirmed the preventive effect of DCQD on ALI, and found that DCQD can improve the protective mechanism of ALI by regulating the expression of HIF-1α, down-regulating glycolysis and reducing inflammation.
