Ginkgo biloba and Panax notoginseng are both herb medicines for cerebrovascular disease, and play an active role in treating ischemic cerebrovascular disease(ICVD). Their mechanisms of action include antioxidant stress, nerve protection, vascular protection. According to the comparative study of literatures, G. biloba has a certain protective effect from the early stage of free radical formation throughout the whole process of causing cell inflammation and apoptosis in antioxidant stress; while P. notoginseng has mainly anti-inflammatory, anti-apoptosis effects. In the nerve protection and repair of nerve damage caused by glutamate, both could promote neurogenesis, repair damaged axons and protect nerve cells. In addition, G. biloba could also relieve neurotoxicity caused by glutamate damage, while P. notoginseng have a unique effect in repairing blood-brain barrier(BBB) and blood vessel regeneration. In clinic, they are used as auxiliary drugs in combination with thrombolytic therapy, and play curative effects in alleviating inflammation, eliminating edema, improving the cure rate and the prognosis. For cerebral diseases caused by chronic cerebral hypoperfusion, G. biloba could reduce inflammation and improve cognition. In addition, G. biloba could protect neurocyte by adjusting the secretion of dopamine in vivo, and has a certain effect on antidepressant diseases, which however needs further studies.
银杏叶和三七均为治疗脑血管疾病的草药,在治疗缺血性脑血管病(ICVD)中发挥着积极作用。它们的作用机制包括抗氧化应激、神经保护、血管保护。根据文献对比研究,银杏叶在抗氧化应激中从自由基形成的早期阶段到引发细胞炎症和凋亡的全过程都具有一定的保护作用;而三七主要具有抗炎、抗凋亡作用。在对谷氨酸引起的神经损伤的神经保护和修复方面,二者均能促进神经发生,修复受损轴突并保护神经细胞。此外,银杏叶还可减轻谷氨酸损伤引起的神经毒性,而三七在修复血脑屏障(BBB)和血管再生方面具有独特作用。在临床上,它们作为辅助药物与溶栓治疗联合使用,在减轻炎症、消除水肿、提高治愈率和改善预后方面发挥疗效。对于慢性脑灌注不足引起的脑部疾病,银杏叶可减轻炎症并改善认知。此外,银杏叶可通过调节体内多巴胺的分泌来保护神经细胞,对抑郁症有一定作用,不过这还需要进一步研究。
