Abstract

Insights

Jiawei Shengjiangsan (JWSJS) effectively reduced kidney inflammation and injury in diabetic nephropathy mice. Its mechanism involves inhibiting the PI3K/Akt/NF-κB signaling pathway, improving kidney function and pathology.

Area of Science:

  • Pharmacology
  • Nephrology
  • Traditional Chinese Medicine

Background:

  • Diabetic nephropathy (DN) is a major complication of diabetes, leading to significant kidney damage.
  • Current treatments for DN have limitations, necessitating the exploration of novel therapeutic agents.
  • Jiawei Shengjiangsan (JWSJS) is a traditional Chinese medicine with potential renoprotective properties.

Purpose of the Study:

  • To investigate the therapeutic mechanism of JWSJS in a mouse model of diabetic nephropathy.
  • To evaluate the effects of JWSJS on kidney injury markers and inflammatory pathways.

Main Methods:

  • db/db mice were treated with varying doses of JWSJS or Perindopril for 12 weeks.
  • Serum creatinine (SCr), blood urea nitrogen (BUN), and urinary albumin were measured.
  • Levels of inflammatory cytokines (TNF-α, IL-1β, VCAM-1, MCP-1), NGAL, and HbA1c were assessed via ELISA.
  • Protein expression of PI3K/Akt/NF-κB signaling pathway components was analyzed using Western blot.
  • Renal histopathology was examined to evaluate kidney damage.

Main Results:

  • JWSJS treatment significantly reduced SCr, BUN, urinary albumin, NGAL, HbA1c, and inflammatory markers (TNF-α, IL-1β, VCAM-1, MCP-1) compared to the model group.
  • JWSJS upregulated the expression of p-PI3K and p-Akt while downregulating p-NF-κB p65.
  • Histological analysis showed JWSJS ameliorated renal tubular and glomerular damage, and improved podocyte injury.

Conclusions:

  • JWSJS exhibits significant renoprotective effects in diabetic nephropathy.
  • The therapeutic mechanism of JWSJS is associated with the inhibition of the PI3K/Akt/NF-κB signaling pathway.
  • JWSJS demonstrates potential as a treatment for diabetic nephropathy by reducing inflammation and improving kidney structure.
