脊髓损伤后神经缺损的有效修复仍然是临床治疗的挑战。随着干细胞和再生医学的发展,目前常用的脊髓损伤细胞治疗包括促进内源性干细胞分化、神经干细胞、嗅鞘细胞以及雪旺细胞等移植治疗。然而,不同细胞来源的干细胞均存在各自的局限性... 脊髓损伤后神经缺损的有效修复仍然是临床治疗的挑战。随着干细胞和再生医学的发展,目前常用的脊髓损伤细胞治疗包括促进内源性干细胞分化、神经干细胞、嗅鞘细胞以及雪旺细胞等移植治疗。然而,不同细胞来源的干细胞均存在各自的局限性,而联合应用针灸治疗能够直接调控内源性神经干细胞的增殖和分化、促进外源性移植细胞的存活和向损伤局部的迁移、促进轴突再生以及修复脊髓继发性损伤的微环境。在后续研究中应围绕参数标准化、再生精准化和方案制度化,推动针灸联合细胞移植方法在脊髓损伤诊疗方案中的应用。 展开更多

The National Strong Motion Observation Network System (NSMONS) of China is briefly introduced in this paper. The NSMONS consists of permanent free-field stations, special observation arrays, mobile observatories and a network management system. During the Wenchuan Earthquake, over 1,400 components of acceleration records were obtained from 460 permanent free-field stations and three arrays for topographical effect and structural response observation in the network system from the main shock, and over 20,000 components of acceleration records from strong aftershocks occurred before August 1, 2008 were also obtained by permanent free-field stations of the NSMONS and 59 mobile instruments quickly deployed after the main shock. The strong motion recordings from the main shock and strong aftershocks are summarized in this paper. In the ground motion recordings, there are over 560 components with peak ground acceleration (PGA) over 10 Gal, the largest being 957.7 Gal. The largest PGA recorded during the aftershock exceeds 300 Gal. 展开更多

DNA nanotechnology enables precise organization of nanoscale objects with extraordinarily structural programmability.Self-assembled DNA nanostructures possess a lot of interesting features,such as designable size and shape,and structural addressability at nanometer scale.Taking advantage of these properties,DNA nanostructures could work as templates or molds for the controllable synthesis of functional nanomaterials,such as organic macromolecules,metallic or inorganic nonmetallic nanomaterials.In this review,we summarize the recent progress in the shape-controllable synthesis of functional nanomaterials on DNA templates.The potential application fields of these nanomaterials are also discussed. 展开更多
