Original magnification ×200. a, bone destruction; b, immune cell infiltration; c, hypertrophic synovium. (b) Histopathology scores of synoviocyte hyperplasia and inflammatory cell infiltration in all groups. ^∗P < 0.05, ^∗∗P < 0.01 when compared with the control group; ^#P < 0.05, ^##P < 0.01 when compared with the vehicle group.
