Heyingwuzi formulation alleviates diabetic retinopathy by promoting mitophagy via the HIF-1α/BNIP3/NIX axis

Figure 7 Heying wuzi formulation reduced pathological damage to retinal tissues. A: The impact of heying wuzi formulation (HYWZF) on weight; B: The impact of HYWZF on blood glucose changes; C: The number of ganglion cells in retinal tissues by tar violet staining (scar bar: 50 μm); D: Hematoxylin and eosin staining was used to observe retinal tissue structure (scar bar: 50 μm); E: Periodic acid-shiff staining was used to detect the number of acellular capillaries in retinal tissues (scar bar: 50 μm). Compared with the con group, ^bP value < 0.01; compared with the diabetic model group, ^dP value < 0.01. HYWZF: Heying wuzi formulation; mod: Diabetic model; Con: Control.
