Key Points

  • The aim is to explore the effects of Jianpi Bushen Formula on motor function and mechanisms in ALS model mice.
  • Randomly assigned ALS mice into model and treatment groups.
  • Administered Jianpi Bushen Formula and saline for 8 weeks.
  • Observed behavior, muscle strength, and fatigue resistance weekly.
  • Analyzed spinal cord tissue for pathological changes and protein expression using various methods.
  • Treatment group showed reduced weight loss compared to the model group.
  • Fatigue resistance in treatment group was less impaired than in the model group.
  • Grip strength decline was slower in the treatment group compared to the model group.
  • Treatment group exhibited reduced neuron apoptosis and structural integrity in spinal motor neurons.
  • Less mitochondrial swelling and demyelination were observed in the treatment group compared to the model group.

Abstract

目的 探索健脾补肾方对肌萎缩侧索硬化(ALS)模型小鼠运动功能的影响及其机制。方法 将12只采取转基因法繁育的保留部分运动功能的ADAR2flox/flox/VAChT-Cre小鼠(AR2小鼠)随机分为模型组和治疗组,每组6只;以6只同批次野生型(WT)小鼠为对照组。治疗组小鼠灌胃给予健脾补肾方30 g/(kg·d),对照组和模型组小鼠灌胃给予0.2 mL氯化钠溶液(9 g/L),每日1次,连续干预8周。每周观察小鼠活动状况、体质量以及抓力、抗疲劳能力(滚轮测试)等行为学功能。第24周后取样,采用苏木精-伊红(HE)染色法、尼氏染色法观察各组小鼠脊髓前角组织病理变化,采用Western blot法检测各组小鼠脊髓组织中作用于RNA的腺苷脱氨酶2(ADAR2)、转录反应DNA结合蛋白-43(TDP-43)的蛋白表达量,透射电镜观察小鼠脊髓组织超微结构。结果 与对照组比较,模型组小鼠体质量随周龄逐渐增长;与模型组比较,治疗组小鼠体质量降低。与对照组比较,模型组小鼠与治疗组小鼠抗疲劳程度均有所下降,但是治疗组小鼠的抗疲劳能力下降相对模型组有所延缓。与对照组比较,模型组小鼠抓力下降;与模型组比较,治疗组抓力下降相对减缓。与对照组相比,模型组TDP-43表达量显著降低(P0.05)。与对照组相比,模型组脊髓前角运动神经元损伤严重,神经元结构不完整;与模型组相比,治疗组神经细胞凋亡数量减少。透射电镜下,模型组与对照组比较出现明显的线粒体肿胀凋亡、髓鞘脱散现象;治疗组与对照组相比较存在部分髓鞘脱散、线粒体肿胀,相对于模型组,存在肿胀凋亡现象的神经细胞数量有所减少。结论 健脾补肾方能延缓ALS模型小鼠运动功能的减退,减少脊髓运动神经元的凋亡和损伤,阻止散发性ALS(sALS)病理异常标志物TDP-43的生成,保护脊髓神经元有髓神经纤维与线粒体,有效延缓ALS小鼠疾病的进展与功能的丧失。
