| 摘要: |
| 目的 观察滋肾活血方对血管性痴呆（vascular dementia，VD）大鼠海马组织自噬标记蛋白LC3II、Beclin1以及自噬调控PINK1/Parkin信号通路的影响。方法 改良2-VO法建立VD大鼠模型，采用滋肾活血方进行干预，免疫组化法检测VD大鼠海马组织LC3II、Beclin1、PINK1以及Parkin蛋白的表达。结果 滋肾活血方能显著提高VD大鼠海马组织自噬标记蛋白LC3II、Beclin1以及自噬调控PINK1/Parkin信号分子的表达（P<0.01）。结论 滋肾活血方可能通过激活PINK1/Parkin信号通路，促进细胞自噬，保护VD大鼠海马神经元，改善其学习记忆能力。 |

| Abstract: |
| Objective To observe the effects of Zishen Huoxue Decoction on the autophagy related protein LC3II and Beclin1, and autophagy regulation PINK1/Parkin signaling molecules in hippocampal of rats with vascular dementia (VD). Methods The modified 2-VO method was used to establish the VD rat model. The expressions of LC3II, Beclin1, PINK1 and Parkin proteins in the hippocampal of VD rats were detected by immunohistochemistry after the intervention with Zishen Huoxue Decoction. Results The expression of LC3II, Beclin1 and autophagy regulation PINK1/Parkin signaling molecules in the hippocampal of VD rats were significantly improved after the intervention with Zishen Huoxue Decoction (P<0.01). Conclusion Zishen Huoxue Decoction may improve autophagy, protect hippocampal neurons of VD rats, and improve learning and memory ability by activating PINK1/Parkin signaling pathway. |
