摘要
目的:确定基质金属蛋白酶-2(MMP-2)及金属蛋白酶组织抑制剂-2(TIMP-2)在寻常型银屑病发病中的作用及阿维A对其的调节作用。方法:应用双抗体夹心酶联免疫吸附法(ELISA)检测30例寻常型银屑病患者经阿维A治疗前后外周血清中MMP-2及TIMP-2的水平。结果:寻常型银屑病患者血清中MMP-2、TIMP-2、MMP-2/TIMP-2的水平较正常人对照组显著增高(P<0.001)。治疗后血清中MMP-2、TIMP-2、MMP-2/TIMP-2较治疗前显著下降(P<0.01)。结论:阿维A可通过降低血清MMP-2,升高TIMP-2水平而起到治疗作用。
Objective: To determine the effect of acitretin on MMP - 2 and TIMP- 2 and to explore its treatment mechanism in the patients with psoriasis vulgaris. Methods: Serum levels of MMP - 2 and TIMP - 2 were measured by double antibody sandwich enzyme - linked innnunosorbent assay (ELISA) in 30 patients with psoriasis vulgaris before and after treatment with acitretin. Results: The senml levels of MMP-2, TIMP-2 and MMP-2/TIMP-2 were significantly higher than those in normal controls ( P 〈 0. 001 ) and were significantly higher before the treatment than after treatment ( P 〈 0.01 ). Conclusion: The results indicate that the therapeutic effect of acitretin in the treatment psoriasis vulgaris may be by inhibiting the secretion of MMP - 2 and increasing the level of TIMP - 2.
