Abstract

Aim

This study aimed to investigate the mechanism of Si Shen Decoction (SSD) in rats with Collagen-Induced Arthritis (CIA).

Background

Rheumatoid arthritis (RA) is a complex immune disease characterized by bilateral symmetrical multi-joint pain and swelling. SSD has shown good results in treating RA in clinical applications, but its mechanism of action remains unclear.

Objective

To investigate the mechanism of SSD in rats with Collagen-Induced Arthritis (CIA).

Methods

Bioinformatics and network pharmacology analyses were used to predict the possible treatment targets and signaling pathways. Elisa, Western blotting, and quantitative real-time polymerase chain reaction were used to verify the mechanism of SSD in the treatment of RA.

Results

FABP4, MMP9, and PTGS2 were the most common predicted therapeutic targets. SSD treatment significantly reduced synovitis, ankle swelling and bone erosion in CIA rats. The SSD group also significantly reduced the serum secretion of CRP, TNFα, and IL1β, decreased mRNA levels of FABP4, IKKα, and p65 in the synovial membrane, but increased PPARγ. Western blot showed that SSD treatment could significantly reduce the expression of FABP4, IKKα, and phosphorylated p65 (p-p65) proteins in the synovium. SSD was found to inhibit the FABP4/PPARγ/NFκB signaling pathway and reduce the inflammatory response in CIA rats. The therapeutic effect of SSD was significant with the increase of dose.

Conclusion

SSD can relieve joint symptoms in CIA rats and alleviate inflammation by inhibiting the FABP4/PPARγ/NFκB signaling pathway. The effect of high-dose SSD was more prominent.
