Spine J:高龄患者急性脊髓损伤功能恢复差且与损伤严重程度相关

2014-07-29 orthowhq 丁香园

在未来40年中,美国65岁以上人口将翻番,人口平均寿命的延长引起社会人口结构再分布,可引起创伤性脊髓损伤流行病学改变,老年人比例增多。因此,有必要探讨年龄对创伤性脊髓损伤临床疗效的影响。现有证据表明,尽管老年人创伤性脊髓损伤运动功能恢复与年轻人类似,但长期随访疗效欠佳。但,这些探讨年龄对临床疗效影响的研究基于损伤严重程度相同的假定。现有的评估脊髓损伤严重程度的常用标准为美国脊髓损伤协会(A

在未来40年中,美国65岁以上人口将翻番,人口平均寿命的延长引起社会人口结构再分布,可引起创伤性脊髓损伤流行病学改变,老年人比例增多。因此,有必要探讨年龄对创伤性脊髓损伤临床疗效的影响。

现有证据表明,尽管老年人创伤性脊髓损伤运动功能恢复与年轻人类似,但长期随访疗效欠佳。但,这些探讨年龄对临床疗效影响的研究基于损伤严重程度相同的假定。现有的评估脊髓损伤严重程度的常用标准为美国脊髓损伤协会(ASIA)损害量表(AIS),将脊髓损伤分为A, B, C和D四级。

加拿大多伦多大学多伦多西部医院神经脊柱外科的学者,进行了一项多中心的数据库联合分析研究,提示高龄患者脊髓损伤功能恢复差,且与损伤严重程度相关,文章于2014年7月发表在Spine J上。

该多中心研究共纳入376例成人(16岁以上)急性创伤性脊髓损伤的病例,平均年龄43.2岁。所有病例在受伤3天内做过神经功能检查,进行ASIA运动评分,ASIA感觉评分和总体AIS分级。所有病例均于伤后24小时甲强龙冲击治疗并行脊髓减压手术。术后随访时间为6月(66例)或1年(310例)。

评价的主要指标为术后1年功能独立测量的运动评分。对老年患者的界定,采用65岁和60岁两个标准分别加以分析。采用多变量回归分析,比较年龄对伤后3天内美国脊髓损伤协会损害量表分值和随访独立测量的运动评分的影响,评估年龄对不同损伤严重程度功能恢复的影响。

研究结果显示,所有病例中65岁以上41例(10.9%),单变量分析提示运动功能恢复或美国脊髓损伤协会损害量表分值无年龄相关差异。但术后1年独立测量的运动评分,老年组明显低。多变量回归分析提示,年龄对急性脊髓损伤分级和随访功能恢复有显著影响。

总体而言,老年脊髓损伤病例,随访运动功能差,且在AIS B和C级病例中最明显,A和D的病例次之。

以上结果提示,急性创伤性脊髓损伤病例,高龄患者功能恢复差,此效应因脊髓损伤严重程度不同而异。这些发现有助于临床中医患的沟通,也利于制定个体化治疗和康复计划。

Neuroscience:脊髓损伤小鼠的免疫功能被成功恢复

据物理学家组织网8月7日(北京时间)报道,美国俄亥俄州立大学维克斯纳医疗中心脑和脊髓修复中心的研究人员开展的一项最新研究显示,脊髓损伤小鼠的免疫功能有可能得到恢复。该结果已经发表在《神经科学》杂志上。 脊髓损伤的人往往免疫功能也受到损伤,这使他们更易被感染。这些人的免疫力遭到抑制的原因不明,但这项新研究发现,一种被称为自主神经反射异常的疾病可以引起免疫抑制。 自主神经反射异常是高位脊髓损伤患者

2013 CNS/AANS 急性颈椎和脊髓损伤管理指南

近期,由美国神经外科医师大会(CNS)和美国神经外科医师协会(AANS)发布的关于急性颈椎及脊髓损伤的最新循证医学指南首次明确指出,急性脊髓损伤后早期不推荐使用类固醇,这项新推荐是112项循证学推荐之一。 神经外科医师协会会长威斯康辛大学麦迪逊分校医学和公共卫生学院神经外科教授Daniel K. Resnick说,之前有关类固醇激素使用的推荐称,只要医生认识到使用这些药物导致损害的几率高于其使用

STM:对大脑的电刺激可在大鼠脊髓损伤后促进其行走

在所有瘫痪的病人中大约有一半会终身离不开轮椅。据一项在大鼠中进行的新研究披露,深部脑刺激可帮助瘫痪病人重新获得行走的能力。脊髓是由神经纤维束从大脑通过一个脊椎骨管道下行而成的。中脑运动区或MLR是位于原始脑核中的指挥中心,而该原始脑核被称为脑干,它会与这一神经网络交流而影响运动。在所有的物种中,包括从刺鳐和蝾螈到猫和猴子,其MLR都非常相似。人们已知,用电脉冲刺激这个部分的

J Neurosci:衰老会加剧脊髓损伤的损害程度

最近研究人员发现,在骨髓损伤的复杂环境中,老年小鼠中枢神经系统中的免疫细胞无法激活一个重要的信号通路,这大大降低了损伤后的修复机会。相关研究结果发表在最近的神经科学主流期刊《神经科学杂志》(Journal of Neuroscience)。     这些研究首次表明,与年轻成年小鼠相比,老年小鼠的脊髓损伤更加严重,证实了以前来自临床设置的调查结果。他们还

CNS Neurosci Ther:氢气治疗脊髓损伤的机制研究

第二军医大学长征医院麻醉科学袁红斌教授课题组,前期研究证明,氢气对脊髓损伤的具有治疗作用,但对其治疗作用机制并不十分了解。最近袁红斌教授课题组进一步研究证明,氢气所以能治疗脊髓损伤,主要是通过抑制氧化损伤相关星形胶质细胞增生,并对和星形胶质细胞增生关系密切的细胞信号分子STAT3磷酸化、活性氧和相关炎症因子的变化进行的分析。该研究目前已经发表在CNS Neurosci Ther. 脊髓损伤是导

NRR:脊髓损伤患者进行跑台步行训练改善运动能力

大量证据表明,跑台步行训练能促进腰骶段脊髓完全横断大鼠脊髓通路重建,但由于无法确定动物运动功能恢复是来自于跑台步行训练还是动物的自发性步行训练,所以,对不完全损伤后跑台步行训练的效果仍有争论。 《中国神经再生研究(英文版)》杂志2013年9月第27期出版的一项研究的结果显示,第10胸椎段脊髓不完全损伤大鼠进行跑台步行训练后,脊髓损伤组织周围生长相关蛋白43的表达量明显增加,且第2腰椎脊髓纤维
