Before the treatment, healthy subjects and osteoarthritis(OA) patients with knee joint effusion were assigned to the serum control group and the synovial fluid control group, respectively; during the treatment, RA patients with damp-heat-obstruction symptom pattern were divided into two groups:one is combined group that was administered Sanhuangyilong decoction plus MTX; the other group was MTX group that received MTX only. The expression levels of TNF-α and IFN-γ in the serum and synovial fluid were measured with enzyme-linked immunosorbent assay(ELISA) before and after the treatment, and the peripheral blood levels of erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and disease activity score in 28 joints(DAS28)were determined.RESULTS: Before treatment, the serum levels of TNF-α and IFN-γ in the RA patients with dampheat-obstruction symptom pattern were higher than those in healthy control group(P < 0.05).The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those in the serum of the RA patients(P < 0.05). The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those of the sy-novial fluid of the osteoarthritis patients(P < 0.05).The expression of TNF-α and IFN-γ in the serum and synovial fluid of the RA patients had no correlation with the inflammatory activity index ESR, CRP,or DAS28(P > 0.05). After 2 weeks of treatment, the expression level of TNF-α and IFN-γ in the combined group had increased, although the difference was not statistically significant(P > 0.05); in contrast, ESR, CRP, and DAS28 decreased, and the difference was statistically significant(P < 0.01). After 4 weeks of therapy, TNF-alpha and IFN-γ, ESR,CRP, and DAS28 in the combined group decreased compared with the before-treatment levels(P <0.01). After 2 w of treatment, the differences in the TNF-α and IFN-γ expression levels in the combined group were not statistically significant(P > 0.05)compared with that in the MTX group, although there were statistically significant differences in the ESR, CRP, and DAS28(P < 0.05). After 4 weeks of treatment, differences in TNF-α, IFN-γ, ESR, CRP, and DAS28 in the combined group compared with MTX group were statistically significant(P < 0.01).CONCLUSION: TNF-α and IFN-γ might be involved in the development of RA. The RA patients with damp-heat-obstruction symptom pattern show better benefits from the treatment of Sanhuangyilong decoction plus MTX, and the treatment is superior to that of using MTX only.展开更多
