重组人红细胞生成素与β-七叶皂甙钠对大鼠脊髓损伤后功能恢复和神经细胞继发性损伤的影响

摘要

目的:研究重组人红细胞生成素与β-七叶皂甙钠对大鼠脊髓损伤后功能恢复、神经细胞继发性损伤的影响.方法:选择雌性成年SD大鼠共50只,依据其损伤和治疗的情况分为五组.空白组采用等体积生理盐水腹腔注射、损伤组为脊髓打击损伤组,rh-EPO组单纯采取重组人红细胞生成素,β-SE组单纯采取β-七叶皂甙钠治疗,联合治疗组采取重组人红细胞生成素与β-七叶皂甙钠治疗,比较各项指标.结果:联合治疗组BBB 运动功能评分均显著高于rh-EPO组、β-SE组和损伤组;联合治疗组的神经功能优于rh-EPO组、β-SE组;联合治疗组的Ca2+含量显著高于rh-EPO组、β-SE组;联合治疗组的Mg2+含量显著低于rh-EPO组、β-SE组,差异均有显著统计学意义(P<0.05).结论:重组人红细胞生成素与β-七叶皂甙钠联合治疗有助于改善BBB运动功能评分,促进大鼠运动功能恢复,延缓神经细胞继发性损伤的发展.%Objective:To study the effect of recombinant human erythropoietin and β-aescin on functional recovery and secondary injury of nerve cells in rats after spinal cord injury.Methods:A total of 50 female SD rats were randomly divided into five groups according to their injury and treatment.The rats in the rh-EPO group were treated with recombinant human erythropoietin,and the β-SE group was treated with β-aescin,and the combination group was treated with recombinant human erythropoietin and the treatment of β-aescin,compared the indicators.Results: The BBB motor function scores of the combination therapy group were significantly higher than those of rh-EPO group,β-SE group and injury group.The neurological function of the combined treatment group was better than that of rh-EPO group and β-SE group(P<0.05).The content of Mg2+in the combination group was significantly higher than that in the rhEPO group and the β-SE group,and the difference was significant (P<0.05).Conclusion: The combination of re-combinant human erythropoietin and β-aescin can help improve the BBB motor function score,promote the recovery of motor function and delay the development of secondary injury of nerve cells.
