文题释义:
丙泊酚的神经保护作用:
丙泊酚可能通过降低代谢率、减少脑组织耗氧;抑制线粒体通透性转换孔,抗脂质过氧化反应;激活细胞外调节蛋白激酶转导的通路;抑制细胞钙超载及炎性细胞因子表达,抑制细胞凋亡等机制来发挥神经保护作用。
舒芬太尼的神经保护作用:舒芬太尼可能是通过抑制炎性反应过度表达,调节神经损伤局部及相应脊髓节段组织Bcl-2和Caspase-3的表达,抑制神经细胞凋亡,起到减轻神经损伤的作用。

 

摘要
背景:
临床工作中发现,舒芬太尼及丙泊酚对神经系统损伤有很好的保护作用。
目的:观察丙泊酚联合舒芬太尼在脐血间充质干细胞移植治疗脊髓损伤中的作用。
方法:取Wistar大鼠45只,采用Allens重物坠落法制备急性脊髓损伤模型,脊髓损伤后6 h随机分为3组,联合组尾静脉注射脐血间充质干细胞悬液0.5 mL(细胞浓度为1×105 L-1),同时尾静脉注射舒芬太尼0.5 μg/kg、丙泊酚1.0-1.5 mg/kg;干细胞组尾静脉注射脐血间充质干细胞悬液0.5 mL(细胞浓度为1×105 L-1);对照组尾静脉注射含体积分数5%胎牛血清LDMEM培养液 30 μL。注射后15,60 min时,检测血清S100β蛋白水平;脊髓损伤后1,2,4,6,8周,检测斜板实验运动功能评分与BBB评分;脊髓损伤后第4周,观察脊髓组织病理变化;脊髓损伤后1,2周,检测血管内皮生长因子蛋白表达。
结果与结论:①干预后15,60 min时,联合组血清S100β蛋白水平低于干细胞组、对照组(P < 0.05),干细胞组低于对照组(P < 0.05);②脊髓损伤后2,4,6,8周,联合组斜板实验运动功能评分与BBB评分高于干细胞组、对照组(P < 0.05),干细胞组高于对照组(P < 0.05);③脊髓损伤后第4周,对照组脊髓组织损伤严重,神经纤维较少;干细胞组可见增生的脊髓组织及少量再生轴突、PKH-26标记的阳性干细胞;联合组可见大量的神经轴索样结构及PKH-26标记的阳性干细胞;④脊髓损伤后1,2周,联合组血管内皮生长因子蛋白高于干细胞组、对照组(P < 0.05),干细胞组高于对照组(P < 0.05);⑤结果表明,丙泊酚、舒芬太尼联合脐血间充质干细胞可加快脊髓损伤大鼠后肢功能的恢复,促进脊髓损伤的修复。

Abstract:

BACKGROUND: Sufentanil and propofol are both found to have good neuroprotective effects on neurological damage in clinical practice.
OBJECTIVE: To investigate the effect of propofol combined with sufentanil in umbilical cord blood mesenchymal stem cells transplantation for the treatment of spinal cord injury.
METHODS: Sixty-five Wistar rats were selected to make animal models of acute spinal cord injury using Allen’s method. Six hours after modeling, these rats were randomly assigned into combined group (injection of 2×107/L human umbilical cord blood mesenchymal stem cell suspension (0.5 mL) plus injection of 1.0-1.5 mg/kg propofol and 0.5 μg/kg sufentanil via the tail vein), stem cell group (injection of 2×107/L human umbilical cord blood mesenchymal stem cell suspension (0.5 mL) via the tail vein), or control group (injection of 30 μL of LDMEM containing 5% fetal bovine serum). S100β protein level in serum was detected in each group at 15 and 60 minutes after injection. Motor function of rat in each group was assessed by Basso Beattie Bresnahan (BBB) scoring and incline plane test at 1, 2, 4, 6, 8 weeks after modeling. Pathological changes of the spinal cord were observed at 4 weeks after modeling. Expression of vascular endothelial growth factor was detected using western blot assay at 1 and 2 weeks after modeling.
RESULTS AND CONCLUSION: After 15 and 60 minutes of intervention, S100β protein level was lowest in the combined group followed by the stem cell and control groups (P < 0.05). At 2, 4, 6, 8 weeks after modeling, scores on the incline plane test and BBB were ranked as follows: combined group > stem cell group > model group (P < 0.05). At 4 weeks after modeling, severe damage to the spinal cord and few nerve fibers were found in the control group; spinal cord hyperplasia and a few of regenerated axons and PKH-26-positive stem cells appeared in the stem cell group; while in the combined group, there were a large amount of PKH-26-positive stem cells and nerve axon-like structures. At 1 and 2 weeks after modeling, the highest protein level of vascular endothelial growth factor was found in the combined group followed by the stem cell group and control group (P < 0.05). To conclude, these findings indicate that propofol and sufentanil in umbilical cord blood mesenchymal stem cell transplantation therapy can promote the recovery of hindlimb function after spinal cord injury, thereby promoting the functional recovery of rats from spinal cord injury.
