title: [Effect of 10-Hydroxycamptotbecine on the proliferation of human Fibroblast-like Synoviocyte with Rheumatoid Arthritis].
abstract: Objective:To study the effect of 10-Hydroxycamptothecine (10-HCPT) on the proliferation and apoptosis of human Fibroblast-like Synoviocyte (FLS) with Rheumatoid Arthritis (RA).Methods:Different concentrations of 10-HCPT and Methotrexate (MTX) were used to treat FLS cells in RA and Osteoarthritis (OA) for different time (24, 48, and 72 hours), and FLS cells without 10-HCPT and MTX were served as the control group. CCK-8 assay were applied to determine the proliferation of FLS cells, Annexin-V APC/7-AAD staining were used to detect the apoptosis of FLS cells.Results:The survival rate of FLS cells were (66.68±0.48) %, 48 h; (60.09±0.95) %, 72 h and (44.05±1.29) %, 48 h; (30.63±1.79) %, 72 h, when the concentrations were 1.0 μg/ml and 10.0 μg/ml in 10-HCPT group. Compared with the control group, the survival rate of FLS cells in RA and OA both declined in treatment groups with different concentrations of 10-HCPT and MTX. With the extension of time, the survival rate of FLS cells declined significantly. Compared with the MTX group, there were no obvious differences in 10-HCPT group with 1.0 μg/ml. But the concentration of 10.0 μg/ml of 10-HCPT group showed obviously difference in the proliferation of FLS cells. The apoptosis rate of FLS cells were (66.68±0.48) %, 48 h; (60.09±0.95) %, 72 h and (44.05±1.29) %, 48 h; (30.63±1.79) %, 72 h, when the concentrations were 1.0 μg/ml and 10.0 μg/ml in 10-HCPT group. Compared with the control group, two concentrations of 10-HCPT and MTX induced higher apoptosis in FLS cells with RA and OA; with the extension of time (72 h), the rate of apoptosis was significantly enhanced (P<0.05). When FLS cells with RA were treated for 48 h, apoptosis of 10-HCPT group was higher than that of MTX group. The 10.0 μg/ml of 10-HCPT had the highest effect.Conclusion:Compared with MTX, 10-HCPT had the higher efficacy of inhibiting proliferation and promoting apoptosis in FLS cells.
