摘要/Abstract

摘要：

目的观察脊髓损伤患者大脑中央前回初级运动皮质(M1)代谢变化。方法 2018年12月至2019年10月,选择住院脊髓损伤患者20例(患者组)和健康人15例(对照组),使用磁共振波谱(MRS)观察大脑左侧M1感兴趣区氮-乙酰天门冬氨酸(NAA)、胆碱(Cho)、肌酸(Cr)和肌醇(MI)浓度。结果患者组MI浓度较对照组明显增高(t = 3.745, P < 0.01),NAA、Cho、Cr、NAA/Cr、Cho/Cr、Cho/NAA与对照组相比无显著性差异( t < 1.431, P > 0.05)。结论脊髓损伤患者M1区可能有胶质细胞增生,提示发生代偿性修复。

Abstract:

Objective To investigate the changes of metabolite concentration in the precentral gyrus (primary motor cortex, M1) in spinal cord injury (SCI) patients.Methods From December, 2018 to October, 2019, 20 SCI patients and 15 healthy controls were scaned with magnetic resonance spectroscopy to measure the concentrations of N-acetylaspartate (NAA), choline (Cho), creatine (Cr) and myo-inositol (MI) in region of interest (ROI) of left M1. Results Concentration of MI was more in the patients than in the controls (t = 3.745, P < 0.01). There was no significant difference in the concentrations of NAA, Cho and Cr, as well as the ratios of NAA/Cr, Cho/Cr, Cho/NAA between the patients and the controls ( t < 1.431, P > 0.05). Conclusion There may be hyperplasia of glial cells in M1 of SCI patients, indicating compensatory repair in cerebral motor cortex.

Key words: spinal cord injury, magnetic resonance spectroscopy, precentral gyrus, primary motor cortex, gial cells, hyperplasia, repair
