    Abstract:
    OBJECTIVE: To explore the effect of Jinwu Jiangu Recipe (JJR) on the expression of synovial cells' nuclear factor-kappaB (NF-kappaB) and serum interleukin 17 (IL-17) in collagen induced arthritis (CIA) rats. METHODS: Totally 60 Wistar rats were randomly divided into 6 groups, i.e., the blank control group, the model group, high, middle, and low dose JJR treatment groups, and the tripterygium control group, 10 in each group. Except rats in the blank control group, CIA model was established in rats of the rest 5 groups. Then they were treated from the 7th day of modeling. After 4 weeks of medication they were sacrificed, serum collected, and synovium of joints were isolated. The expression of serum IL-17 was detected in synovium of joints by enzyme linked immunosorbent assay (ELISA). And the expression of NF-kappaB/P65, Ikappabetaalpha and NF-KappaB/P50 were detected by Western blot. RESULTS: Compared with the blank control group, the serum IL-17 level increased in the model group (P <0. 01). Compared with the model group, the serum IL-17 level obviously decreased in high and middle dose JJR groups and the tripterygium control group (P < 0.01). Results of Western blot showed, when compared with the blank control group, protein activities of NF-kappaB/P65 and NF-kappaB/P50 were significantly enhanced in the model group (P < 0.01). Compared with the model group, protein activities of NF-kappaB/P65 and NF-kappaB/P50 significantly decreased in high and middle dose JJR groups and the tripterygium control group (P < 0.05, P < 0.01). All indices mentioned above were higher in the low dose JJR group than in the tripterygium control group (P < 0.05, P < 0.01). CONCLUSION: JJR could lower the expression of serum IL-17 in CIA model rats, and inhibit protein activities of NF-kappaB/P65 and NF-kappaB/P50.
