B Immunohistochemical analysis of RAF in knee synovial. C The effect of GA on the expression of RAF, ERK, and p-ERK in ankle synovial. D The effect of GA on the expression of RAF, ERK, and p-ERK in knee synovial. *P < 0.05, **P < 0.01, and ***P < 0.001 compared with the control group. $P < 0.05, $$P < 0.01, and $$$P < 0.001 compared with model group
