Key Points

  • The research aims to investigate the biological basis of yin deficiency syndrome in Parkinson's disease (PD) rats and the intervention effects of Compound Dihuang Granule (CDG).
  • Developed PD rat model via 6-hydroxydopamine (6-OHDA) stereotaxic injection.
  • Divided successful models into Model, CDG, Erastin+CDG, and Sham groups.
  • Conducted treatment for 4 weeks and observed general conditions and neurological behaviors.
  • Analyzed striatal and brain tissue through immunohistochemistry and transmission electron microscopy.
  • Used Western blotting to assess protein expression levels of key markers.
  • CDG and Erastin+CDG groups improved motor dysfunction in PD rats.
  • Both treatments reduced dopaminergic neuronal damage and mitochondrial morphology issues.
  • Decreased levels of ferroptosis-related proteins ACSL4 and PTGS2 were observed.
  • Increased expression of the protective protein GPX4 was noted.

Abstract

目的 探究阴虚动风证帕金森病(PD)证候生物学基础及复方地黄颗粒(CDG)的干预作用。 方法 6-羟基多巴胺(6-OHDA)脑立体定位注射制备PD阴虚动风证大鼠模型,将成功模型大鼠随机分为Model组、CDG组、Erastin+CDG组,另纳入大鼠为Sham组。连续治疗4周。观察大鼠一般体征及神经行为学测试,收集大鼠纹状体以及全脑。免疫组织化学染色法(IHC)检测黑质和纹状体TH的表达;透射电镜法观察大鼠纹状体组织中线粒体的病理变化。蛋白质免疫印迹法(WB)检测酪氨酸羟化酶(TH)、酰基辅酶A合成酶长链家族成员4(ACSL4)、环氧合酶(PTGS2)、谷胱甘肽过氧化物酶4(GPX4)表达。 结果 CDG组、Erastin+CDG组能改善阴虚动风证PD大鼠运动障碍,改善PD多巴胺神经元损伤及线粒体形态,降低铁死亡相关蛋白ACSL4、PTGS2蛋白表达,增加GPX4蛋白表达。 结论 阴虚动风证PD大鼠模型的证候生物学基础与铁死亡相关,复方地黄颗粒缓解阴虚动风证PD大鼠DA神经元损伤作用机制与抑制铁死亡相关。
