Figure Lengend Snippet: Construction of CKM mouse model: Renal Part: (A) Serum indicators of uric acid, creatinine, and urea nitrogen, (B) quantification of kidney weight, (C) typical images evaluated using two staining methods for Renal pathological changes: In the HFD group, glomeruli are normal in size and shape with clear boundaries. The glomerular capsule is very distinct. In the CKM group, glomeruli are deformed, enlarged, filled with blood cells, and capillaries are dilated. There is fat deposition in the renal tubular interstitium (black arrow), and inflammatory cell deposition (red arrow). MASSON staining shows significant fibrosis in the glomeruli and renal interstitium of the CKM group (blue area). (D) Renal injury score based on HE staining.
