This study was aimed at clarifying the mechanism of Gandi capsule (GDC) ameliorating DN by regulating the lipid metabolism of podocytes. Network pharmacology methods were performed to screen the key molecules and potential targets of GDC for constructing the molecular\u2010protein interaction network of GDC and conducting signal pathway enrichment analysis. GDC was predicted to ameliorate DN through SIRT1\/AMPK\/HNF4A pathway. Our results showed that GDC improved renal function in db\/db mice. Besides, GDC exhibited effectiveness in relieving kidney tissue damage and renal lipid accumulation in db\/db mice, and same effects were present in GDC\u2010active ingredient baicalin. We further proved the new role of HNF4A in the lipid metabolism of DN mediated by SIRT1 and AMPK signaling pathways. The results suggested decreased expression of SIRT1 and p\u2010AMPK<jats:italic>\u03b1<\/jats:italic> in the kidney tissue and increased expression of HNF4A of db\/db mice compared with the control group. GDC and baicalin could reverse these expression changes. Furthermore, similar expression changes were observed in the murine podocyte cell line (MPC\u20105) treated with different concentrations of GDC and baicalin. Our research suggested that GDC and its active ingredient baicalin could alleviate the abnormal lipid metabolism in the kidney of db\/db mice and might exert renal protection through the SIRT1\/AMPK\/HNF4A pathway.<\/jats:p>","DOI":"10.1155\/2022\/6275505","type":"journal-article","created":{"date-parts":[[2022,4,18]],"date-time":"2022-04-18T22:50:09Z","timestamp":1650322209000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Gandi
