The inhibitory environment that surrounds the lesion site and the lack of intrinsic regenerative capacity of the adult mammalian central nervous system (CNS) impede the regrowth of injured axons and thereby the reestablishment of neural circuits required for functional recovery after spinal cord injuries (SCI).To circumvent these barriers,biomaterial scaffolds are applied to bridge the lesion gaps for the regrowing axons to follow,and,often by combining stem cell transplantation,to enable the local environment in the growth-supportive direction.Manipulations,such as the modulation of PTEN/mTOR pathways,can also enhance intrinsic CNS axon regrowth after injury.Given the complex pathophysiology of SCI,combining biomaterial scaffolds and genetic manipulation may provide synergistic effects and promote maximal axonal regrowth.Future directions will primarily focus on the translatability of these approaches and promote therapeutic avenues toward the functional rehabilitation of patients with SCIs.

引:电脑的计算能力在不断提升，迟早有一天会赶上人脑的智力水平吗？未来的计算机不会像今天的这样方头方脑地摆在桌面上吧？未来的电脑和人脑之间，会是一场竞争或战争，还是相互合作或融合呢？美国著名的未来学家Ray Kurzweil最近接受了Computerworld[美]报社的采访，就这些未来的问题进行了大胆的设想。 人脑和电脑的互动研究 有人认为可以对人脑进行“反向研究的工程”，这种设想是相

玉米是重要的粮食、饲料和工业原料作物,在我国国民经济中占有十分重要的地位。近年来,玉米蚜虫危害呈现出日益严重的发展趋势,局部地区已从次要虫害上升为主要虫害,给玉米产量造成了严重损失。本试验以玉米幼胚培养再生体系为基础,利用农杆菌介导法进行抗蚜虫基因的遗传转化研究,旨在通过转化体系的优化将从薄荷中提取的抗蚜虫基因转入受体细胞并再生植株,创造抗蚜虫玉米新种质,为抗蚜虫玉米品种的选育奠定基础。本试验对玉
