摘要
目的探讨窄谱中波紫外线(NB-UVB)对寻常性银屑病患者外周血干扰素诱导的T细胞α趋化因子(I-TAC)表达的影响。方法采用夹心酶联免疫吸附试验(ELISA)检测正常人和寻常性银屑病患者NB-UVB治疗前后外周血I-TAC水平变化。结果寻常性银屑病患者血清I-TAC水平明显高于正常对照组(t=21.37,P<0.05)。经NB-UVB治疗36次后,银屑病患者I-TAC水平较治疗前明显下降(t=18.23,P<0.05),且治疗前后银屑病患者银屑病皮损面积严重度指数(PASI)评分与血清I-TAC水平呈正相关(r=0.293,P<0.05)。结论 NB-UVB可降低寻常性银屑病患者外周血I-TAC水平,在银屑病的发病过程中I-TAC可能发挥重要作用。
Objective To study the effect of the narrow-band ultraviolet B( NB-UVB) on serum levels of IFN-inducible T cell alpha chemoattractant(I-TAC) in psoriasis. Methods Sandwich enzyme-linked immunosorbent assay was used to detect peripheral blood levels of serum I-TAC in psoriasis vulgaris before and after the treatment of NB-UVB and healthy controls. Results The serum level of I-TAC was signifi cant higher in patients with psoriasis vulgaris than those in normal group(t=21.37, P0.05). After the treatment of NB-UVB for 36 times, I-TAC level in psoriasis patients was signifi cantly decreased compared with before the treatment(t=18.23, P0.05). PASI score of psoriasis patients, before and after the treatment, and serum I-TAC levels were positively correlated. Conclusion NB-UVB can reduce the serum level of I-TAC in patients with psoriasis vulgaris, and I-TAC may be involved in valueadded pathogenesis of psoriasis.
