Transcriptomics revealed key pathways, and molecular docking simulated component-target interactions.Results: UPLC-MS confirmed the compositional complexity of MMDH and JGSQ. Network pharmacology indicated their involvement in multiple DN-related pathways. In vitro, JGSQ alleviated fibrosis and enhanced adhesion via FN and E-cad, while MMDH reduced interstitial fibrosis via FN and VIM. Transcriptomics showed JGSQ regulates the TGF-β pathway, and MMDH modulates the TNF pathway. Molecular docking confirmed key components binding to TGFB1 and TNFA.Conclusion: MMDH and JGSQ exhibit distinct chemical compositions, targets, and pathways, underscoring their Yin-Yang regulatory roles in kidney function.
