摘要

Fengshi Gutong (FSGT) capsule, a traditional Chinese medicine formula, has effects including warming meridians and dispersing cold, and relieving pain by dredging collaterals. FSGT is generally used for the treatment of rheumatoid arthritis (RA) in clinic in China.This study aims to investigate the alleviation provided by FSGT capsule on RA in vivo and the engaged mechanism.The collagen-induced arthritis (CIA) mouse model was used to evaluate the alleviation of FSGT capsule on RA in vivo. Network pharmacology was used to find the potential involved molecular targets. Western-blot, Real-time polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA) were conducted. Wound healing assay was performed in human umbilical vein endothelial cells (HUVECs).FSGT capsule (300, 900 mg/kg) alleviated RA in CIA mice with no obvious side effects. The results from network pharmacology showed that the top 6 molecular targets involved in the FSGT-provided alleviation on RA were interleukin 6 (IL-6), tumor necrosis factor α (TNFα), C-C motif chemokine 2 (CCL2), vascular endothelial growth factor (VEGF), intercellular cell adhesion molecule-1 (ICAM-1), interleukin 1β (IL-1β), and these results imply the critical participation of inhibiting inflammation or angiogenesis. Next, FSGT capsule decreased the elevated serum contents of rheumatoid factor (RF) and VEGF, and some pro-inflammatory cytokines like TNFα and IL-6. Moreover, FSGT capsule also reduced the elevated protein expression of ICAM1, IL-1β and phosphorylated protein kinase B (Akt) in synovium from CIA mice. Further in vitro results showed that totally 13 compounds from FSGT reduced the enhanced IL-1β and inducible nitric oxide synthase (iNOS) mRNA expression in RAW264.7 macrophages stimulated by lipopolysaccharide (LPS). Meanwhile, 7 compounds from FSGT decreased the VEGF-induced HUVEC migration. Among those compounds, benzoylhypaconine (BHA), pseudoephedrine hydrochloride (PSE), glycyrrhetnic acid (GA), isoliquiritigenin (ISL), quercetin (QUER) and kaempferol (KAE) were found to inhibit both inflammation and angiogenesis in vitro.FSGT capsule ameliorates RA in CIA mice by reducing inflammation, abrogating angiogenesis and relieving pain. Some compounds in FSGT, including BHA, GA, PSE, ISL, QUER and KAE, reduced both inflammation and angiogenesis in vitro, which suggests that those compounds may contribute to the FSGT capsule-provided alleviation on RA.
