摘要:

目的  通过Meta分析探索精神分裂症高危人群脑内谷氨酸类化合物(glutamineGlx)、谷氨酸(glutamateGlu)的水平对早期识别精神分裂症的神经生化异常的作用。

方法  检索中英文数据库中建库至20201031日的文献,收集比较了精神分裂症高危人群组与正常对照组在磁共振波谱测量下脑内的GlxGlu浓度的差异。

结果  共纳入27篇文献,43组数据,样本量3 875例。Meta分析结果显示,在精神分裂症高危人群丘脑、背外侧前额叶、颞叶的Glu的浓度低于正常对照组,而在其他脑区以及人脑整体没有发现两组间的GlxGlu的差异。

结论  丘脑Glu浓度可能是精神分裂症发作前的风险标志物。

Abstract:

Objective  To explore the effects of the levels of glutamine(Glx) and glutamate(Glu) on the early identification of neurobiochemical abnormalities in high-risk people with schizophrenia through Meta-analysis.

Methods  The literature was retrieved from Chinese and English databases from the establishment to October 31,2020, and the differences of Glx and Glu concentrations in the brain measured by magnetic resonance spectroscopy(MRS) were collected and compared between high-risk group of schizophrenia and the normal control group.

Results  A total of 27 articles, 43 groups of data and a sample size of 3 875 were included. Meta-analysis results showed that the concentration of Glu in the thalamus, dorsolateral prefrontal lobe and temporal lobe in the high-risk group of schizophrenia was lower than that in the normal control group, while no difference in Glx or Glu was found in other brain regions or the whole brain between two groups.

Conclusion  Glu concentration in the thalamus may be a risk marker before the onset of schizophrenia.
