摘要
目的：探讨无抽搐电休克治疗(modified electroconvulsive therapy，MECT)对精神分裂症患者认知功能及其氧化自由基清除剂的影响。方法：对符合国际疾病分类(10th International Classification of Diseases，ICD-10)诊断标准的精神分裂症患者进行前后对照研究，共收集50例。在MECT前后，对患者进行认知功能测评，检测基线血清超氧化物歧化酶(superoxide dismutase，SOD)、一氧化氮(NO)和谷胱甘肽过氧化物酶(GSH-Px)水平，探索MECT对患者认知功能影响及与氧自由基及其清除剂的相关性。结果：1)MECT治疗前后P300的N1潜伏期缩短，P3波幅降低，心理测试颜色连线测验、Stroop色词测验、威斯康星卡片分类测验(WCST-128)正确应答数及持续错误数差异有统计学意义(P<0.05)；2)治疗前后SOD，GPX差异无统计学意义，NO水平较治疗前降低，差异有统计学意义(P<0.05)；3)MECT治疗前NO水平与精神分裂症患者的认知功能有相关性。结论：1)MECT治疗对精神分裂症患者的认知功能是有改善的；2)MECT治疗后患者NO水平降低，且治疗前的NO水平与患者的认知功能有一定的相关性，提示其可能在认知功能中起一定的作用。

Abstract
Objective: To study effect of modified electroconvulsive therapy on the cognitive function and oxygen free radicals in schizophrenic patients. Methods: A before and after treatment controlled study was carried out. A total of 50 schizophrenic meeting a diagnostic criteria of 10 th International Classification of Diseases (ICD-10) were recruited. To assess cognitive function and serum SOD, NO and GSH-Px. Results: Part of neuropsychological and electrophysiological testing results were improved after treatment. NO difference were found in serum SOD and GPX level before and after treatment (P<0.05). While serum NO level was lower after therapy. Before treatment there was relationship between serum NO level and cognitive function. Conclusion: The cognitive function of schizophrenic was improved by MECT. There was relationship between serum NO level and cognitive function before therapy, which suggests NO may play a role in cognitive function.
