ABSTRACT
Objective To detect the expression levels of peripheral blood CXCL10 and its receptor CXCR3 and T cell subsets in of the patients with advanced vitiligo and the influence of compound Chinese medicine on it.Methods Flow cytometry was used to detect the cellular proportions of peripheral blood T cell subsets,ELISA was employed to quantify serum CXCL10 and CXCR3 expression levels before and after treatment.Results After 1 month of taking Chinese medicine,the proportions of CD3+ CD4+ cells and CD3+ CD8+ cells were increased compared before treatment(P＜0.05).The expression level of peripheral serum CXCL10 before treatment was significantly increased compare with the healthy control group(P＜0.01),and the CXCL10 level after treatment was decreased significantly compared with that before treatment(P＜0.05).The expression level of peripheral serum CXCR3 was significantly increased compared with the healthy control group(P＜0.05),while which after treatment was still significantly higher than that in the healthy control group(P＜0.05).Conclusion CXCL10,CXCR3 and T cell subsets proportion may be involved in the pathogenesis of vitiligo.The compound Chinese medicine used in this study plays the curative effect possibly by regulating T cell subsets and expression levels of CXCL10 and CXCR3.
ABSTRACT
Objective To research the change rule of peripheral serum Th1/Th2/Th17 balance and relevant cytokines in atopic dermatitis(AD) and to further study its immunologic mechanism .Methods The levels of peripheral serum IFN‐γ,IL‐4 ,IL‐17 ,IL‐21 and IL‐23 in the patients with AD were detected by the flow immunofluorescence technology and the detection results were performed the statistical analysis ,thus the change rule of Th1/Th2/Th17 balance in AD was analyzed .Results The IL‐4 level in peripheral serum of the patients with AD was increased compared with the healthy control group (P<0 .05);the IFN‐γ/IL‐4 and IFN‐γ/IL‐17 in the AD group were significantly decreased compared with the control group (P<0 .01);IL‐17 was positively corre‐lation with SCORAD scores of AD severity (P<0 .05) .Conclusion Th1/Th2 and Th1/Th17 are decreased in the AD course .Th1/Th2/Th17 balance drift may be the important mechanism of AD pathogenesis .
