Table 1 Primer Pair Sequence of Target Genes

Figure 1 Effect of Yishen capsule on 24-hour urinary microalbumin and pathological changes of kidney. (A) The level of 24-hour urinary microalbumin in each group. (B) Histopathological changes in each group. (*P < 0.05. Black arrows represent glycogen expression. Red arrows represent edema and vacuolar degeneration of renal tubular epithelial cells and mesangial cell proliferation, matrix accumulation).

Abbreviations: N, normal group; DN, diabetic nephropathy group; YS, Yishen capsule group; R, resveratrol group.

Figure 2 Differentially expressed genes (DEGs) of the normal group versus DN group and YS group. (A) The volcano map of 321 DEGs between the normal group and DN group. (B) The volcano map of 261 DEGs between DN group and YS group. (C) Hierarchical clustering analysis of kidney samples between normal group, DN group and YS group, from 3 independent rats. The abscissa represents the log2FoldChange, and the ordinate indicates -log10 (p-value) of gene expression between the two groups. Up-regulated genes were red dots and down-regulated genes were blue dots.

Figure 5 Effect of Yishen capsule on NOD like receptor signaling pathway. (A) Immunohistochemistry staining for NLRP3, caspase-1 and IL-1β (×400). (B) The mRNA expression of NLRP3, caspase-1 and IL-1β. (*P < 0.05. Red arrows indicate the expression of target proteins detected by immunohistochemistry, with brown particles in glomerular, renal tubular epithelial cells).
