To compare the neuroprotective effects of methylprednisolone (MPSS) and rosiglitazone (ROSG) following spinal cord injury (SCI).
This study was carried out at the Institute of Orthopedics, the First Affiliated Hospital of Soochow University, Suzhou, China between June 2009 and March 2010. One hundred and twenty Sprague-Dawley rats after SCI were divided into 4 different groups (30/group): i) SCI-vehicle group, ii) MPSS group, iii) ROSG group, and iv) sham saline group. The following 5 aspects were evaluated: 1) spinal cord inflammation and tissue injury; 2) neutrophil infiltration; 3) cell apoptosis; 4) the expression of proinflammatory cytokines tumor necrosis factor-α and interleukin-β; and 5) the expression of tissue Bax, Bcl-2, and HSP70 proteins in situ.
Notably, ROSG showed similar neuroprotective effects to MPSS, and significantly decreased spinal cord damage, apoptosis, and cytokine expression. There were no significant differences between the MPSS or ROSG-treated groups.
Administration of ROSG after SCI reduces the development of inflammation and tissue injury associated with spinal cord trauma.
比较甲基强的松龙(MPSS)和罗格列酮(ROSG)对脊髓损伤(SCI)后的神经保护作用。
本研究于2009年6月至2010年3月在中国苏州大学附属第一医院骨科研究所进行。120只脊髓损伤后的Sprague-Dawley大鼠被分为4组(每组30只):i)SCI-载体组,ii)MPSS组,iii)ROSG组,iv)假生理盐水组。评估以下5个方面:1)脊髓炎症和组织损伤;2)中性粒细胞浸润;3)细胞凋亡;4)促炎细胞因子肿瘤坏死因子-α和白细胞介素-β的表达;5)组织Bax、Bcl-2和HSP70蛋白的原位表达。
值得注意的是,ROSG显示出与MPSS相似的神经保护作用,并显著降低了脊髓损伤、凋亡和细胞因子表达。MPSS或ROSG治疗组之间无显著差异。
脊髓损伤后给予ROSG可减少与脊髓创伤相关的炎症和组织损伤的发展。
