缺血性中风是人类发病率和死亡率的主要原因之一。脑缺血再灌注损伤是脑卒中的主要原因。北五味子是我国著名的传统中药。本研究探讨了S.结果表明,当归总皂苷对大鼠大脑中动脉闭塞再灌注模型的脑缺血再灌注有明显的保护作用,并探讨了其可能的作用机制。我们发现,GJ减少神经评分,脑梗死,并在I/R大鼠脑含水量。重要的是,GJ挽救了I/R治疗-减少了海马神经元的存活,抑制了I/R大鼠缺血组织的凋亡,增加了B细胞淋巴瘤-特大(Bcl-XL)的表达,并降低了I/R大鼠脑组织中裂解的caspase-3、Bax、环氧合酶-2、核因子κ B和一氧化氮的水平。此外,GJ处理增强核因子E2相关因子2(Nrf 2)易位,血红素加氧酶-1(HO-1)的表达,超氧化物歧化酶和谷胱甘肽过氧化物酶的活性,谷胱甘肽水平。总体而言,GJ处理GJ通过在体内诱导抗凋亡、抗氧化和抗炎作用来减弱CIR损伤。
Ischemic stroke is one of the leading causes of morbidity and mortality in humans. Cerebral ischemia-reperfusion (CIR) injury serves as a leading cause of stroke. Schisandra chinensis is a well-known Chinese traditional medicine. In this study, we explored the role of Gomisin J (GJ), a compound of S. chinensis, in CIR using a middle cerebral artery occlusion/reperfusion rat model and the possible mechanisms. We identified that GJ reduced neurological scores, cerebral infarction, and water content in the I/R rat brain. Importantly, GJ rescued I/R treatment-reduced neuron survival in the hippocampus, inhibited apoptosis of ischemic tissues in I/R rats, increased B-cell lymphoma-extra-large (Bcl-XL) expression, and reduced the levels of cleaved caspase-3, Bax, cyclooxygenase-2, nuclear factor kappa-B, and nitric oxide in I/R rat brain tissues. Furthermore, GJ treatment enhanced nuclear factor E2 related factor 2 (Nrf2) translocation, heme oxygenase-1 (HO-1) expression, superoxide dismutase and glutathione peroxidase activities, and glutathione level. Overall, GJ treatment GJ attenuates CIR injury by inducing anti-apoptotic, antioxidant, and anti-inflammatory effects in vivo.
