Effect of Fengshi Qutong Capsule on Function of Human Synovial Cells in Rheumatoid Arthritis Induced by TNF-α / 中国实验方剂学杂志

ABSTRACT

Objective: To study the effects of Fengshi Qutong capsule (FSQTC) on proliferation, migration, adhesion, invasion and secretion of human synovial cells in rheumatoid arthritis (RA) induced by tumor necrosis factor-α (TNF-α) and explore its mechanism. Method: Human synovial cells (MH7A) in RA patients were induced in vitro by using TNF-α (20 μg·L-1). After treatment with different concentrations of FSQTC (0.02,0.1,0.5 μg·L-1), MTT colorimetric assay, transwell migration, adhesion and invasion tests were used to detect the proliferation, migration, adhesion and invasion of the MH7A, respectively. The expression levels of vascular endothelial growth factor (VEGF) and interleukin-1β (IL-1β) in MH7A supernatant were detected by enzyme linked immunosorbent assay (ELISA). Result: As compared with blank control group, TNF-α (20 μg·L-1) significantly increased the proliferation, migration, adhesion, invasion and secretion of IL-1β and VEGF of MH7A cells (P-1) had no significant effect on proliferation of TNF-α-induced MH7A cells after treatment for 24 hours. After 48 hours of treatment, proliferation of MH7A cells induced by TNF-α was decreased in a concentration-dependent manner (PPPPConclusion: FSQTC can inhibit the proliferation, migration, adhesion, invasion and secretion of IL-1β and VEGF in MH7A cells.
