摘要:

疼痛是一种与脊髓损伤(SCI)自然病变、神经系统结构受损以及存活组织继发性病理生理改变相关的带衰弱性质的病变结果。约有三分之二的SCI患者经受着持续性临床疼痛的折磨,其中三分之一患者病况严重。脊髓损伤后疼痛可随时间的延长而增强,并且常规治疗方式往往难以治愈。在过去的十年里,临床研究表明,脊髓损伤后疼痛会影响患者的康复过程、日常活动和生活质量,可能会对情绪造成严重影响进而导致抑郁,甚至自杀。SCI引起的慢性神经病理性疼痛的机制目前还不是很清楚,但痛觉纤维异常发育中心已普遍被认为是脊髓损伤疼痛的机制,并与SCI9-11诱发机械性异常疼痛相关。美国约翰霍普金斯大学医学院的Feng Tao教授认为少突胶质细胞损伤和死亡诱导的脱髓鞘(髓鞘缺失)和髓鞘形成障碍(异常髓鞘形成)是导致SCI相关行为缺陷,包括疼痛的主要原因。例如,脊髓损伤引起的髓鞘形成障碍会参与到痛觉纤维异常发育,进而造成脊髓损伤疼痛行为。因此,脱髓鞘/髓鞘形成障碍可能是修复治疗脊髓损伤的重要疗法,并且是脊髓损伤后功能恢复和异常发育预防的关键要素之一。

Abstract:

Transient ischemic attack (TIA) is a temporary event, which portends a higher risk of a disabling stroke following the TIA. However, the evaluation and management of TIA vary worldwide and is debated and controversial. Dr. Mohamed Al-Khaled from University of Lübeck in Germany considered With the development of brain imaging, particularly diffusion weighted imaging-magnetic resonance imaging (DWI-MRI), the diagnosis of TIA changed from time-based definition to a tissue-based one. DWI-MRI became a mandatory tool in the TIA workup. The DWI-MRI provides not only the evidence to distinguish between TIA and acute ischemic stroke, furthermore it predicts TIA patients who are at higher risk of disabling stroke, which can be prevented by an immediate evaluation and treatment of TIA These findings, published in the Neural Regeneration Research (Vol. 9, No. 3, 2014).
