摘要:

背景:建立一种成功率较高、安全可靠的标准脊髓横断模型是研究脊髓修复的前提条件。

目的:评价大鼠脊髓横断模型制备的价值及椎板切除对脊髓的影响。

方法:检索美国国立医学图书馆(PubMed)、中国知网(CNKI)、重庆维普(VIP)、万方数据库中所用关于大鼠脊髓横断模型的随机对照研究。

结果与结论:11篇随机对照研究符合纳入标准(英文2篇,中文9篇),共394只大鼠纳入研究,脊髓半横断组与椎板切除组1-6周内下肢运动功能评分(BBB评分)、4周内电生理差异有显著性意义(WMD=-12.86,95%CI-16.10至-9.62,P < 0.01)、(WMD=15.36,95%CI 11.36-19.36,P < 0.01),半横断组6周后BBB评分差异无显著性意义(WMD=-10.28;95%CI -24.20-3.64;P=0.15);脊髓全横断组与椎板切除组1-6周内BBB评分、4周内电生理差异有显著性意义(WMD=-18.83,95%CI -20.64至-17.01,P < 0.01)、(WMD= -11.21,95%CI -16.35至-6.08,P < 0.01)。椎板切除组与正常组4周内BBB评分与电生理评分差异无显著性意义(WMD=-0.00,95%CI -0.01-0.01,P=1)、(WMD= 0.43,95%CI -0.35-1.21,P=0.28);大鼠脊髓横断组和椎板切除组死亡数差异无显著性意义(RD=0.05,95%CI -0.03-0.13;P=0.26)。说明脊髓横断法是一种稳定性好、可复制性强、存活率高的脊髓损伤研究模型,但其横断的准确性、术后护理及对照组的设立有待商榷。

Abstract:

BACKGROUND: Establishing a highly successful, safe, reliable standard spinal cord transection model is the precondition of studying spinal cord injury repair.

OBJECTIVE: To evaluate the value of preparing spinal cord transection model in rats and the effects of laminectomy on spinal cord.

METHODS: We searched the randomized controlled trials involving rat models of spinal cord transection in the databases of PubMed, CNKI, VIP and WanFang.

RESULTS AND CONCLUSION: 11 randomized controlled trials (RCTs) met the inclusion criteria (two in English, 9 in Chinese), and a total of 394 rats were included in the study. There were significant differences in the lower limb motor function scores (BBB scores) within 1-6 weeks after injury (WMD=-12.86, 95%CI -16.10 to -9.62, P < 0.01) and electrophysiological indices within 4 weeks after injury (WMD=15.36, 95%CI 11.36 to 19.36, P < 0.01) between spinal cord hemisection group and laminectomy group. The BBB scores after 6 weeks were not significantly different between these two groups (WMD=-10.28; 95%CI -24.20 to 3.64; P=0.15). There were significant differences in the lower limb motor function scores (BBB scores) within 1-6 weeks after injury (WMD= -18.83, 95% CI -20.64 to -17.01, P < 0.01) and electrophysiological indices within 4 weeks after injury (WMD= -11.21, 95%CI -16.35 to -6.08, P < 0.01) between spinal cord transection group and laminectomy group. No significant differences were found in BBB scores (WMD= -0.00, 95%CI -0.01 to 0.01, P=1) and electrophysiological indices (WMD=0.43, 95%CI -0.35 to 1.21, P=0.28) within 4 weeks after injury between laminectomy group and normal group. There was no significant difference in the number of deaths between spinal cord hemisection group and laminectomy group (RD=0.05, 95%CI -0.03 to 0.13; P=0.26). Experimental findings indicate that spinal cord transection is a method of inducing spinal cord injury with good stability, strong replication and high survival rate. But transection accuracy, postoperative care and designation of control group remain open to question.
