Objective To explore the correlation between Th1,Th2,Th17,and Treg cells differentiation and related cytokines in patients with rheumatoid arthritis (RA).Methods Seventy-one patients with active RA were enrolled in this study.They were divided into low,moderate and high disease activity groups according to disease activity score (DAS28).The frequencies of Th1,Th2,Th17,and Treg cells in the peripheral blood of RA patients group (n=71) and healthy conlrol group (n=18) were determined by flow cytometry.T test was used for statistical analysis.Results Significant difference could be detected between the proportions of Th1 [ (6.2±4.5)%],Th17 [ (1.1±0.9)%] and Treg [(1.8±1.2)%] cells in the peripheral blood of RA patients and the control group (P<0.05),and there was correlation between proportions of these three kinds of cell and the DAS28.Conclusion Th1 and Th 17 cells may promote the development of RA disease,but Th2 and Treg cells could prevent further development of RA disease.

Inflammatory bowel disease is thought to be regulated by the balance between Th1 and Th2 cytokines secreted by T cells, and NF-kappaB p65 also plays a predominant role in the intestinal inflammation. We evaluated the potency of oxymatrine, one of active components of Sophora Root, in inhibiting the immune responses and inflammation in 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis. The inflammation was markedly ameliorated in the oxymatrine-treated rats. The level of IL-2 was increased and that of IL-10 was decreased in colon tissue in the rat model, which was reversed by the treatment of oxymatrine. Moreover, the elevated expression of NF-kappaB p65 in colon tissue in the model was also improved by oxymatrine treatment. Our results suggest that oxymatrine might be beneficial for the abnormal immune responses and inflammation by regulating the unbalance of Th1 and Th2 cytokines secretion and inhibiting the expression of NF-kappaB p65 in colon tissue.
