Neurogenesis and Regeneration of Nervous Tissue

701
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

科学领域:

  • 整形外科 整形外科 整形外科
  • 放射学 放射学是一门学科.
  • 生物化学 生物化学

背景情况:

  • 椎间盘退化是腰部疼痛的常见原因之一.
  • 手术的目的是减少轴负荷并恢复圆盘高度.
  • 非侵入性地评估盘代谢对于了解治疗疗效至关重要.

研究的目的:

  • 在手术减少轴负荷后评估椎间盘代谢.
  • 通过使用延迟加多增强的软骨MRI (dGEMRIC) 来评估糖氨基甘氨酸含量的变化.
  • 为了将手术结果与磁盘健康和患者报告的疼痛相关联.

主要方法:

  • 十六名患有腰椎退化 (L4-L5或L5-S1) 的患者接受了后腰融合与脊椎间分心.
  • 延迟加多增强的软骨MRI (dGEMRIC) 用于评估手术前和后的葡萄糖氨基酸含量.
  • 收集了患者报告的结果,包括视觉模拟量表 (VAS) 和奥斯威斯特残疾指数 (ODI).

主要成果:

  • 手术后观察到VAS (P=.003) 和ODI (P=.0004) 的显著改善.
  • 经过手术的磁盘显示厚度增加 (2.41毫米,P=.0004) 和dGEMRIC信号的显著变化 (P=.0013),表明糖氨酸甘氨酸含量增加.
  • 控制盘显示没有显著变化 (P=.87).

结论:

  • 恢复磁盘高度和降低轴向压力会增加糖氨基甘氨酸含量,这表明磁盘再生.
  • 消除对椎间盘的压力可能会防止退化并启动再生.
  • 手术减压和融合可以积极影响磁盘代谢和患者的结果.
