摘要:

目的 检测巨噬细胞游走抑制因子(MIF)在寻常型白癜风患者外周血单一核细胞(PBMC)、血清及皮肤组织液中的表达,探讨其临床意义。方法 应用实时逆转录PCR及酶联免疫吸附试验检测39例寻常型白癜风患者与31例性别、年龄相匹配的正常人对照者PBMC中MIF mRNA的表达水平及血清、皮肤组织液中MIF的含量。结果 寻常型白癜风患者PBMC中MIF mRNA的表达水平及血清、皮肤组织液中MIF的含量分别为6.70(2.64 ~ 8.65)、32.76(10.67 ~ 40.98) μg/L、167.80(107.40 ~ 219.60) μg/L,显著高于正常人对照组(Z值分别为5.895、5.936、4.715,P值均 < 0.05);进展期白癜风患者分别为7.89(3.89 ~ 9.12)、37.80(29.50 ~ 45.70) μg/L、211.50(131.70 ~ 248.75) μg/L,显著高于稳定期患者(Z值分别为2.213、2.141、2.100,P值均 < 0.05)。白癜风患者PBMC中MIF mRNA的表达水平及血清中MIF的含量与疾病严重程度评分呈正相关(r值分别为0.486、0.453,P值均 < 0.05)。结论 MIF可能在寻常型白癜风的发病过程中发挥一定作用。

Abstract:

Objective To detect the expression levels of macrophage migration inhibitory factor (MIF) in peripheral blood mononuclear cells(PBMCs), sera and skin tissue fluid from patients with vitiligo vulgaris, and to investigate their clinical significance. Methods Thirty-nine patients with vitiligo vulgaris and 31 age- and sex-matched normal human controls were recruited in this study. Real-time reverse transcription-PCR was employed to assess the expressions of MIF mRNA in PBMCs, enzyme-linked immunosorbent assay(ELISA) to detect the concentrations of MIF in sera and skin tissue fluid from these subjects. Results Patients with vitiligo vulgaris showed a significantly higher level of MIF mRNA in PBMCs (6.70 (2.64 - 8.65) vs. 1.67 (1.24 - 2.45), Z = 5.895, P < 0.05), MIF protein in sera (32.76 (10.67 - 40.98) μg/L vs. 7.89 (6.13 - 9.54) μg/L, Z = 5.936, P < 0.05) and skin tissue fluid (167.80 (107.40 - 219.60) μg/L vs. 42.44 (32.29 - 49.74) μg/L , Z = 4.715, P < 0.05) compared with the normal human controls. The expression levels of MIF mRNA in PBMCs, and MIF protein in sera and skin tissue fluid were also higher in patients with progressive vitiligo than in those with stable vitiligo (7.89 (3.89 - 9.12) vs. 5.62 (2.23 - 7.29), Z = 2.213, P < 0.05; 37.80 (29.50 - 45.70) μg/L vs. 22.70 (9.36 - 37.78) μg/L, Z = 2.141, P < 0.05; 211.50 (131.70 - 248.75) μg/L vs. 144.65 (89.13 - 167.30) μg/L, Z = 2.100, P < 0.05). In addition, the vitiligo area severity index (VASI) score was positively correlated with the expression levels of MIF mRNA in PBMCs (r = 0.486, P < 0.05)and MIF protein in sera (r = 0.453, P < 0.05). Conclusion MIF might play a certain role in the pathogenesis of vitiligo vulgaris.
