Ketamine exerts rapid and robust antidepressant properties in both animal models and depressed patients and tramadol possesses potential antidepressant effects. Brain-derived neurotrophic factor (BDNF) is an important biomarker for mood disorders and tropomyosin-related kinase B (TrkB) is a high affinity catalytic receptor for BDNF. We hypothesized that tramadol pretreatment might reinforce ketamine-elicited antidepressant effects with significant changes in hippocampal BDNF and TrkB levels in rats. Immobility time of rats receiving different treatment in the forced swimming test (FST) was observed. Levels of BDNF and TrkB in hippocampus were measured by enzyme linked immunosorbent assay. Results showed that tramadol (5 mg/kg) administrated alone neither elicited antidepressant effects nor altered BDNF or TrkB level. However, pretreatment with tramadol (5 mg/kg) enhanced the ketamine (10 mg/kg) -elicited antidepressant effects and upregulated the BDNF and TrkB levels in hippocampus. In conclusion, tramadol pretreatment reinforces the ketamine-elicited antidepressant effects, which is associated with the increased levels of BDNF and TrkB in rat hippocampus.

Brain-dead donors have become one of the main sources of organs for transplantation in Western countries. The quality of donor organs is closely related to the outcome of the transplantation. Experimental studies have confirmed the inferior graft survival of livers from brain-dead donors compared with those from living donors. Studies conducted in the past 10 years have shown that brain death is associated with effects on the decreased donor organ quality. However, whether the decrease in the viability of donor organs is caused by brain death or by the events before and after brain death remains uncertain. The purpose of this review is to introduce the advances and controversies regarding the influence of brain death on the viability of donor livers and to summarize the mechanisms of the different protective interventions for donor livers.

富含sn-2 DHA脂质对大脑的益处及其酶法合成综述 Review

大脑中二十二碳六烯酸(DHA, ω-3脂肪酸)的含量与中枢神经系统的正常发育和功能维持高度相关。甘油酯sn-2位上的DHA可以被肠黏膜更好地吸收,从而实现机体对DHA的高效利用。然而,如今人们在饮食中摄入较多的饱和脂肪或富含ω-6脂肪酸的油脂,而摄入较少的DHA,从而导致了部分个体在行为和神经生理学方面的缺陷。为了全面了解DHA对大脑的有益功能,本文系统介绍了天然油脂甘油骨架上DHA的位置分布(sn-2和sn-1,3位)特征,并讨论了DHA补充和通过肠-脑轴传递信息的潜在功能机制。肠-脑轴包含的多条双向信息通道为DHA、肠道菌群和大脑健康的相互作用提供了新的研究思路。为了在日常饮食中摄入更多的sn-2 DHA,我们建议通过更为高效和经济的酯交换制造技术生产富含sn-2 DHA脂质,其中需要解决的关键技术包括强化酶的特异性和优化纯化工艺。这类饮食可满足对sn-2 ω-3脂质有强烈需求的人群,特别是婴儿、儿童、孕妇和哺乳期妇女。

回顾人工智能(artificial intelligence, AI)的发展历史,我们可以清晰地看到脑科学给AI领域带来的巨大突破,如深度学习。目前,尽管AI及其应用的发展趋势已经超越了人类的预期,但AI与人类智能之间仍然存在着难以逾越的鸿沟。从脑科学到AI、从了解大脑到模拟大脑,在脑科学与AI研究之间建立起一座桥梁已经成为一种迫切需求。为此,我们首先需要通过研究新型脑成像技术来探索脑科学的秘密,建立大脑的动态连接图谱以及将神经科学实验与理论、模型和统计学相结合等。在此基础上,我们将进一步研究新一代AI理论和方法,从而建立起从机器感知和机器学习到机器思维和机器决策的颠覆性模型和工作模式。与此同时,本文还将讨论在脑科学启发新一代AI过程中的一些机遇与挑战。
