| ［摘要］目的 探讨多发性硬化（MS）患者血清褪黑激素、肿瘤坏死因子-α（TNF-α）和γ-干扰素（IFN-γ）水平变化与致残状况的相关性．方法 收集40例MS患者和30例健康体检者分别作为实验组及对照组，应用酶联免疫吸附法（ELISA）检测实验组与对照组间血清褪黑激素、TNF-α、IFN-γ水平；应用EDSS量表评价所有MS患者致残状况；并进一步对MS患者血清褪黑激素、TNF-α、IFN-γ水平及EDSS评分进行相关性分析． 结果 MS组血清褪黑激素浓度明显低于正常人群（P＜0.01），TNF-α水平明显高于正常对照人群（P＜0.05），2组间比较差异有统计学意义；MS组和对照组之间血清IFN-γ无显著差异．MS患者血清褪黑激素水平与EDSS评分呈显著负相关（r = -0.76，P＜0.01），而TNF-α则呈正相关（r = 0.83 ，P＜0.01），而与IFN-γ无显著相关性（r = 0.17，P ＞0.05 ）．结论 血清褪黑激素的下调及TNF-α的上调可以影响MS患者的炎症反应过程，并与MS患者功能残障程度密切相关；血清褪黑激素及TNF-α可以作为监测MS临床疗效及评估预后的实验室指标. |

| Abstract: |
| ［Abstract］Objective To study the serum levels of melatonin， tumor necrosis factor alpha（TNF-α）and interferon gamma（IFN-γ）in multiple sclerosis（MS） patients and the correlation with disability. Methods Forty patients with multiple sclerosis were collected as MS group and 30 healthy participants were collected as control group. Serum levels of melatonin and cytokines， including IFN-γ and TNF-， were detected in all participants by the enzyme-linked immunosorbent assay（ELISA）method; disability status of patients with MS was evaluated by EDSS scale. The relevant analysis between serum melatonin， TNF-α， IFN-γ levels and EDSS score in patients with MS was conducted. Results The concentration of serum melatonin in MS group was significantly lower than control group（P＜0.01）. TNF-α levels were higher than control group（P＜0.05）and the difference was statistically significant between MS patients and control group. Among MS group and control group， no significant correlation with the serum levels of IFN-γ was seen. The serum melatonin level was inversely correlated with EDSS score in MS patients（r = -0.76，P＜0.01），and positively correlated with TNF-α（r = 0.83，P＜0.01） and as compared to IFN-γ，no significant correlation was found （r = 0.17，P＞0.05）. Conclusion The decrease of melatonin and increase of TNF-α can be a factor in the inflammatory reaction in patients with MS，and is closely related with dysfunction occurring in multiple sclerosis. Serum melatonin and TNF-αcan be used as laboratory indicators to monitor clinical curative effect and evaluate prognosis of MS. |
