CXCL10、CXCR3及T细胞亚群在进展期白癜风患者外周血中的表达及复方中药对其影响

目的 检测进展期白癜风患者外周血中T细胞亚群及趋化因子配体10(CXCL10)及其受俸3(CXCR3)的表这情况,并探索复方中药对其影响.方法 采用流式细胞仪检测治疗前后白癜风患者外周血中T细胞亚群的细胞比例,ELISA法检测治疗前后白癜风患者外周血清中CXCL10及CXCR3水平.结果 服用复方中药1个月后,白癜风患者外周血中CD3+ CD4+、CD3+ CD8+T细胞比例均较治疗前升高(P＜0.05).治疗前外周血清中CXCL10水平较健康对照组明显升高(P＜0.01),治疗后较治疗前明显降低(P＜0.05).治疗前外周血清中CXCR3水平较健康对照组明显升高(P＜0.01),治疗后仍明显高于健康对照组(P＜0.01).结论 CXCL10、CXCR3表达水平及T细胞亚群比例异常可能与白癜风的发病相关,本研究所用的复方中药可能通过调节T细胞亚群、CXCL10及CXCR3的表达水平发挥其治疗作用.

Expression of CXCL10 ,CXCR3 and T cell subsets in peripheral blood and effect of compound Chinese medicine on it in patients with advanced vitiligo

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.
