【摘要】 背景 目前,采用脑涨落图仪分析精神分裂症患者多个脑区神经递质功能特点的研究较多,也有关于
无抽搐电休克疗法(MECT)对精神分裂症患者脑内神经递质影响的研究,但关于 MECT 对精神分裂症患者具体脑区
神经递质影响的研究较少。目的 观察精神分裂症患者 MECT 治疗前后脑内及不同脑区神经递质水平变化而探讨其可
能的神经生物学机制。方法 选取 2019 年 1 月至 2020 年 12 月常州市德安医院收治的签署 MECT 治疗同意书的精神
分裂症患者 51 例,均接受 MECT 治疗且在治疗期间所用抗精神疾病药物剂量保持不变。比较所有患者首次 MECT 治
疗前 24 h 和 MECT 治疗结束后 24 h 阳性和阴性症状量表(PANSS)新 5 因子模型(20 项版)评分、脑内和不同脑区
神经递质水平。结果 与首次 MECT 治疗前 24 h 相比,所有患者 MECT 治疗结束后 24 h 阳性因子、阴性因子、敌对
兴奋、焦虑抑郁、认知功能损伤因子评分及总分,脑内 γ- 氨基丁酸(GABA)水平及左后脑区 GABA、谷氨酸(Glu)
水平均降低,脑内及右前脑区多巴胺(DA)水平升高(P<0.05)。结论 MECT 对精神分裂症患者精神症状有一定治
疗效果,并可能通过影响脑内 GABA 和 DA、左后脑区 GABA 和 Glu、右前脑区 DA 等神经递质水平而发挥神经生物学
机制。

【Abstract】 Background Neurotransmitters in multiple brain regions in schizophrenia patients have been extensively
studied using encephal of luctuograph in terms of functional features,and also been explored using modified electroconvulsive
therapy(MECT)regarding their responses to MECT,but responses of neurotransmitters in a specific region to MECT have
been rarely examined. Objective To examine pre- and post-treatment changes of neurotransmitters in brain and different brain
regions in patients with schizophrenia with MECT,and to investigate the possible neurobiological mechanism of MECT. Methods
Fifty-one schizophrenia patients were recruited from Changzhou Dean Hospital from January 2019 to December 2020. All of
them had signed the written informed consent form of receiving MECT prior to the participation in the study,and received MECT
with unchanged antipsychotic medications during the study period. Scores of new 5-factor model of the PANSS(20 items),
neurotransmitters in brain and different brain regions 24 hours before the first MECT and 24 hours after the end of MECT were
compared among all patients. Results Compared with those 24 hours before the first MECT,scores of positive factor,negative
factor,hostile excitement,anxiety and depression,cognitive and total PANSS score,as well as gamma-aminobutyric acid(GABA)
in brain and left posterior brain region,and glutamate(Glu)in left posterior brain region significantly decreased,but dopamine
