| 1 | GDNF-Enhanced Axonal Regeneration and Myelination Following Spinal Cord Injury is Mediated by Primary Effects on Neurons显示文摘我们先前研究表明胶质细胞源性神经营养因子(GDNF)联合施万细胞移植能促进脊髓损伤后轴突再生和髓鞘形成。然而,GDNF介导这一过程的细胞靶点尚不清楚。在此,我们报道了GDNF可增加在体再生轴突的数目和直径,并促进体外背根神经节神经元的轴突向外生长,提示GDNF对神经元有直接作用。在施万细胞-背根神经节神经元共培养下,GDNF显著增加施万细胞生成的髓鞘数目;GDNF处理对孤立培养的施万细胞增殖无作用,但可促进已与神经轴突有突触联系的施万细胞增殖;GDNF可增加孤立施万细胞中分子量为140kDa的神经细胞黏附分子(NCAM)的表达,但对黏附分子L1表达或神经营养因子NGF、NT3及BDNF分泌没有影响。总之,这些结果支持假设:GDNF提高轴突再生和施万细胞髓鞘形成主要是通过GDNF对神经元的直接作用介导的,并且提示GDNF联合施万细胞移植可能是促进脊髓损伤后轴突再生和髓鞘形成的有效策略之一。 | LIQUN ZHANG ZHENGWEN MA GEORGE M.

| 2 | Surgical intervention combined with weight-bearing walking training improves neurological recoveries in 320 patients with clinically complete spinal cord injury:a prospective self-controlled study显示文摘Although a large number of trials in the SCI field have been conducted,few proven gains have been realized for patients.In the present study,we determined the efficacy of a novel combination treatment involving surgical intervention and long-term weight-bearing walking training in spinal cord injury(SCI)subjects clinically diagnosed as complete or American Spinal Injury Association Impairment Scale(AIS)Class A(AIS-A).A total of 320 clinically complete SCI subjects(271 male and 49 female),aged 16–60 years,received early(≤7 days,n=201)or delayed(8–30 days,n=119)surgical interventions to reduce intraspinal or intramedullary pressure.Fifteen days post-surgery,all subjects received a weight-bearing walking training with the“Kunming Locomotion Training Program(KLTP)”for a duration of 6 months.The neurological deficit and recovery were assessed using the AIS scale and a 10-point Kunming Locomotor Scale(KLS).We found that surgical intervention significantly improved AIS scores measured at 15 days post-surgery as compared to the pre-surgery baseline scores.Significant improvement of AIS scores was detected at 3 and 6 months and the KLS further showed significant improvements between all pair-wise comparisons of time points of 15 days,3 or 6 months indicating continued improvement in walking scores during the 6-month period.In conclusion,combining surgical intervention within 1 month post-injury and weight-bearing locomotor training promoted continued and statistically significant neurological recoveries in subjects with clinically complete SCI,which generally shows little clinical recovery within the first year after injury and most are permanently disabled.This study was approved by the Science and Research Committee of Kunming General Hospital of PLA and Kunming Tongren Hospital,China and registered at ClinicalTrials.gov(Identifier:NCT04034108)on July 26,2019. | Yansheng Liu Jia-Xin Xie Fang Niu Zhexi Xu Pengju Tan Caihong Shen Hongkun Gao Song Liu Zhengwen Ma Kwok-Fai So Wutian Wu Chen Chen Sujuan Gao Xiao-Ming Xu Hui Zhu | 2021 | Neural Regeneration Research2021,16,5: | 3 |

| 5 | Solid-state corrosion of lithium for prelithiation of SiO_(x)-C composite anode with carbon-incorporated lithium phosphorus oxynitride显示文摘In order to address the issues of low initial Coulombic efficiency of SiO_(x)-C composite anode due to the formation of solid electrolyte interphase,irreversible conversion reaction,and large volume change,the prelithiation method using metal lithium has been employed as one of effective solutions.However,violent side reactions with liquid electrolyte for prelithiation lead to low prelithiation efficiency and induce poor interface between the SiO_(x)-C electrode and liquid electrolyte.Here,a new prelithiation method with so called solid-state corrosion of lithium is developed.By replacing liquid electrolyte with solid-state electrolyte of carbon-incorporated lithium phosphorus oxynitride(LiCPON),not only various side reactions associated with metal lithium are avoided,but also the perfect interface is achieved from the decomposition products of LiCPON.The successful implementation of solid-state corrosion prelithiation can be confirmed by changes in optical image,scanning electron microscopy,and X-ray diffraction.Compared with pristine electrode,the initial Coulombic efficiency of the prelithiated electrode using solid electrolyte can be increased by about 10%,reaching 98.6%in half cell and 88.9%in full cell.Compared with prelithiated electrode using liquid electrolyte,the prelithiation efficiency of the prelithiated anode with solid-state corrosion can be increased from 25.7%to 82.8%.Solid-state corrosion of lithium is expected to become a useful method for prelithiation of SiO_(x)-C composite electrode with high initial Coulombic efficiency and large prelithiation efficiency. | Yan Qiao Siyu Yang Ziqiang Ma Yangyuchen Yang Xiang Hong Zhengwen Fu | 2023 | Nano Research2023,16,6: | 0 |
| 6 | All-solid-state thin-film batteries based on lithium phosphorus oxynitrides显示文摘Lithium phosphorus oxygen nitrogen(LiPON)as solid electrolyte discovered by Bates et al in the 1990s is an important part of all-solid-state thin-film battery(ASSTFB)due to its wide electrochemical stability window and negligible low electronic conductivity.However,the ionic conductivity of LiPON about 2×10^(−6) S cm^(−1) at room temperature is much lower than that of other types of solid electrolytes,which seriously limits the application of ASSTFBs.This review summarizes the research and progress in ASSTFBs based on LiPON,in the solid-state electrolyte of LiPON-derivatives with adjustable chemical compositions of the amorphous structure for the improvement of the ionic conductivity and electrochemical stability,in the critical interface issues between LiPON and electrodes,and in preparation methods for LiPON.This review is helpful for people to understand the interface characteristics and various preparation methods of LiPON in ASSTFBs.The key issues to be addressed concern how to develop solid-state electrolyte films with high conductivity and high-quality interface engineering as well as large-scale preparation technology,so as to realize the practical application of highly integrated ASSTFBs. | Wangqi Dai Yan Qiao Ziqiang Ma Tian Wang Zhengwen Fu | 2022 | Materials Futures2022,1,3: | 0 |

| 8 | Elucidating the selectivity of dyotropic rearrangements of β-lactones:a computational survey显示文摘The dyotropic rearrangement of β-lactones is a neglected treasure in the family of multi-bond reactions and pericyclic reactions.Despite its appealing synthetic potential,the complicated migration selectivity greatly limits its widespread application.In this work,we report the first systematic and comprehensive computational study on the dyotropic rearrangements of β-lactones.The use of the double-hybrid functional ensures the accuracy of results.On the basis of the present study and our previous work,five methods to control the reaction selectivity of dyotropic rearrangements of β-lactones have been summarized,providing valuable references for synthetic chemists to design and develop brand-new type dyotropic reactions. | Jingyang Zhang Yumiao Ma Ke Qiu Bo Li Zhengwen Xue Boxue Tian Yefeng Tang | 2022 | Organic Chemistry Frontiers2022,9,2: | 0 |
