2Progress in glial cell studies in some laboratories in China显示文摘Glial cells in the central nervous system(CNS) consist of a heterogeneous population of cell types,each characterized by distinct morphological features,physiological properties,and specific markers.In contrast to the previous view that glial cells were passive elements in the brain,accumulating evidence suggests that glial cells are active participants in various brain functions and brain disorders.This review summarizes recent progress of glial cell studies from several groups in China,ranging from studies about the mechanisms of neuron-glia crosstalking to investigations on the roles of glial cells in various CNS disorders.DUAN ShuMin Institute of Neuroscience,State Key Laboratory of Neuroscience,Shanghai Institutes for Biological Sciences,Chinese Academy of Sciences,Shanghai China,200031 2010Science China(Life Sciences)2010,53,3:11

4A Critical Time-Window for the Selective Induction of Hippocampal Memory Consolidation by a Brief Episode of Slow-Wave Sleep显示文摘Although extensively studied, the exact role of sleep in learning and memory is still not very clear. Sleep deprivation has been most frequently used to explore the effects of sleep on learning and memory, but the results from such studies are inevitably complicated by concurrent stress and distress. Furthermore, it is not clear whether there is a strict time-window between sleep and memory consolidation. In the present study we were able to induce time-locked slow-wave sleep(SWS) in mice by optogenetically stimulating GABAergic neurons in the parafacial zone(PZ), providing a direct approach to analyze the influences of SWS on learning and memory with precise time-windows. We found that SWS induced by light for 30 min immediately or 15 min after the training phase of the object-in-place task significantly prolonged the memory from 30 min to 6 h. However, induction of SWS 30 min after the training phase did not improve memory, suggesting a critical time-window between the induction of a brief episode of SWS and learning for memory consolidation.Application of a gentle touch to the mice during light stimulation to prevent SWS induction also failed to improve memory, indicating the specific role of SWS,but not the activation of PZ GABAergic neurons itself, in memory consolidation. Similar influences of light-induced SWS on memory consolidation also occurred for Y-maze spatial memory and contextual fear memory, but not for cued fear memory. SWS induction immediately before the test phase had no effect on memory performance, indicating that SWS does not affect memory retrieval. Thus, by induction of a brief-episode SWS we have revealed a critical time window for the consolidation of hippocampusdependent memory.Yi Lu Zheng-Gang Zhu Qing-Qing Ma Yun-Ting Su Yong Han Xiaodong Wang Shumin Duan Yan-Qin Yu 2018Neuroscience Bulletin2018,34,6:9
5Standardized Operational Protocol for Human Brain Banking in China显示文摘With the progress of society, there is an increasing need to tackle disorders of the central nervous system. Human brain tissue, unlike animal tissues, is an irreplaceable resource for the study of neurological diseases (1)Aimed at scientific research and education, the roles of human brain tissue repositories are to acquire brain tissue from donors, prepare, process, and preserve collected samples,provide tissue to specific eligible facilities, and determine the characteristics of each tissue sample.Wenying Qiu Hanlin Zhang Aimin Bao Keqing Zhu Yue Huang Xiaoxin Yan Jing Zhang Chunjiu Zhong Yong Shen Jiangning Zhou Xiaoying Zheng Liwei Zhang Yousheng Shu Beisha Tang Zhenxin Zhang Gang Wang Ren Zhou Bing Sun Changlin Gong Shumin Duan Chao Ma 2019Neuroscience Bulletin2019,35,2:6
6Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting.Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu 2021Cancer Communications2021,41,9:5
7Anterograde Trans-Synaptic Tagging Mediated by Adeno-Associated Virus显示文摘Trans-neuronal viral tracing is becoming one of the most important methods for mapping neuronal circuit connections,but an anterograde trans-synaptic tracer compatible with functional assays is still lacking.Adeno-associated virus(AAV)is replication-defective,and its production of offspring needs the help of adenovirus(AV)[1]or herpesvirus co-infection[2].The replication deficiency,non-pathogenicity,easy manipulability。Fei Zhao Hai-Fei Jiang Wen-Bo Zeng Yousheng Shu Min-Hua Luo Shumin Duan 2017Neuroscience Bulletin2017,33,3:4
8Brain-wide Mapping of Mono-synaptic Afferents to Different Cell Types in the Laterodorsal Tegmentum显示文摘The laterodorsal tegmentum(LDT) is a brain structure involved in distinct behaviors including arousal,reward, and innate fear. How environmental stimuli and top-down control from high-order sensory and limbic cortical areas converge and coordinate in this region to modulate diverse behavioral outputs remains unclear.Using a modified rabies virus, we applied monosynaptic retrograde tracing to the whole brain to examine the LDT cell type specific upstream nuclei. The LDT received very strong midbrain and hindbrain afferents and moderate cortical and hypothalamic innervation but weak connections to the thalamus. The main projection neurons from cortical areas were restricted to the limbic lobe, including the ventral orbital cortex(VO), prelimbic, and cingulate cortices. Although different cell populations received qualitatively similar inputs, primarily via afferents from the periaqueductal gray area, superior colliculus, and the LDT itself, parvalbumin-positive(PV?) GABAergic cells received preferential projections from local LDT neurons.With regard to the different subtypes of GABAergic cells, aconsiderable number of nuclei, including those of the ventral tegmental area, central amygdaloid nucleus, and VO, made significantly greater inputs to somatostatinpositive cells than to PV?cells. Diverse inputs to the LDT on a system-wide level were revealed.Xiaomeng Wang Hongbin Yang Libiao Pan Sijia Hao Xiaotong Wu Li Zhan Yijun Liu Fan Meng Huifang Lou Ying Shen Shumin Duan Hao Wang 2019Neuroscience Bulletin2019,35,5:3

10Effect of integrated Traditional Chinese and Western Medicine on Gout显示文摘OBJECTIVE:To evaluate the curative effect of integrated Traditional Chinese and Western Medicine on gout,and to investigate the therapy timing and exact treatment options of integrated medicine.METHODS:Totally 860 patients were enrolled,including 460 patients with intermittent gout,200 patients with active Traditional Chinese Medicine(TCM)syndrome(TCM syndrome score≥6)and200 patients with stable TCM syndrome(score<6).They were randomly divided into intervention and control groups.The control group was treated according to Western Medicine guidelines.The intervention group was treated with integrated Traditional Chinese and Western Medicine.The efficacy of TCM syndrome,joint pain score,joint swelling score,ESR,C-reactive protein,serum uric acid,liver and kidney function,and the duration of remission of TCM syndrome were compared between the two groups before and after treatments.RESULTS:For the patients with stable TCM syndrome,there was no significant difference in the effective rate and inefficiency between the intervention group and the control group.For the active type,the effective rate of the intervention group is better than the control group significantly.For the stable type,there was no significant difference between the intervention group and the control group in improving the scores of joint pain and swelling,reducing the level of ESR,C-reactive protein,serum uric acid and improving liver and kidney function.For the active type,the differences between the two groups were significant.The stable stage of gout in the intervention group was longer than the control group.CONCLUSION:For the gout patients with stable TCM syndrome in the acute stage of gout,we can use TCM treatment or Western Medicine alternatively;for the patients with active TCM syndrome,the scheme of combination of Traditional Chinese and Western Medicine can be applied,with the better curative effect than any medicine alone.LIU Wei WU Yuanhao XUE Bin JIN Yue ZHANG Shumin LI Peihao XIE Qing WANG Aihua GAO Jingyue CAI Yue ZHANG Bo LIU Xiaoya WANG Yi DUAN Ran 2021Journal of Traditional Chinese Medicine2021,41,5:3
11Lysosomal Exocytosis in Schwann Cells Contributes to Axon Remyelination显示文摘髓鞘形成是一个包括协同性的胞吐、内吞、mRNA转运和细胞骨架的动态变化的复杂过程。尽管髓鞘的异常在溶酶体贮积症中很常见,但对溶酶体在髓鞘形成和维持中所扮演的角色仍不清楚。本文发现Schwann细胞中的晚期内涵体/溶酶体包含大量的髓鞘蛋白P0,含量占超过一半的外周神经系统中的致密髓鞘的总蛋白并且在不同的刺激下表现出Ca2+依赖性的胞吐作用。Rab27a(一种将分泌溶酶体运输至细胞膜的小GTP酶)下调,极大地阻碍了Schwann细胞中的溶酶体胞吐作用,减少了再生坐骨神经的髓鞘形成。这些发现强调了Schwann细胞中溶酶体的新角色,提示调节Schwann细胞中的溶酶体胞吐作用在外周神经系统中有很重要的生理和病理意义。GANG CHEN ZHIJUN ZHANG ZHONGYA WEI QIONG CHENG XIA LI WEI LI SHUMIN DUAN AND XIAOSONG GU 2012神经损伤与功能重建2012,7,3:3
12Anxiolytic Effect of Increased NREM Sleep after Acute Social Defeat Stress in Mice显示文摘Social defeat stress(SDS)plays a major role in the pathogenesis of psychiatric disorders like anxiety and depression.Sleep is generally considered to involve recovery of the brain from prior experience during wakefulness and is altered after acute SDS.However,the effect of acute SDS on sleep/wake behavior in mice varies between studies.In addition,whether sleep changes in response to stress contribute to anxiety is not well established.Here,we first investigated the effects of acute SDS on sleep/wake states in the active period in mice.Our results showed that total sleep time(time in rapid eyemovement[REM]and non-REM[NREM]sleep)increased in the active period after acute SDS.NREM sleep increased mainly during the first 3 h after SDS,while REM sleep increased at a later time.Then,we demonstrated that the increased NREM sleep had an anxiolytic benefit in acute SDS.Mice deprived of sleep for 1 h or 3 h after acute SDS remained in a highly anxious state,while in mice with ad libitum sleep the anxiety rapidly faded away.Altogether,our findings suggest an anxiolytic effect of NREM sleep,and indicate a potential therapeutic strategy for anxiety.Xiang Feng Hui-Ying Zhao Yu-Jin Shao Hui-Fang Lou Li-Ya Zhu Shumin Duan Yan-Qin Yu 2020Neuroscience Bulletin2020,36,10:2
13Trafficking pathway between plasma membrane and mitochondria via clathrin-mediated endocytosis显示文摘Endocytosis is a basic cellular process that describes a form of active transport across the plasma membrane into the cell.The endocytic pathway consists of distinct membrane compartments;internalized molecules are delivered to early endosomes,and some of them are recycled back to the surface,whereas other molecules are sent to late endosomes and lysosomes for degradation.However,little is known about how mitochondria are involved in the endocytic pathway.Here,we report that FM dyes, membrane-impermeant fluorescent lipid probes,can traffic to mitochondria directly from the plasma membrane by clathrinmediated endocytosis.FM dye entry into mitochondria uses microtubule-dependent active transport,but the mechanism is different from the classical endocytic pathway.Hence,this study reveals a previously unrealized lipid trafficking pathway from the plasma membrane to mitochondria.Zhongya Wei Wenfeng Su Huifang Lou Shumin Duan Gang Chen 2018Journal of Molecular Cell Biology2018,10,6:2

16Lysosomal Hydrolase Cathepsin D Non-proteolytically Modulates Dendritic Morphology in Drosophila显示文摘The main lysosomal protease cathepsin D(cathD)is essential for maintaining tissue homeostasis via its degradative function,and its loss leads to ceroid accumulation in the mammalian nervous system,which results in progressive neurodegeneration.Increasing evidence implies non-proteolytic roles of cathD in regulating various biological processes such as apoptosis,cell proliferation,and migration.Along these lines,we here showed that cathD is required for modulating dendritic architecture in the nervous system independent of its traditional degradative function.Upon cathD depletion,class I and class III arborization(da)neurons in Drosophila larvae exhibited aberrant dendritic morphology,including overbranching,aberrant turning,and elongation defects.Reintroduction of wild-type cathD or its proteolyticallyinactive mutant dramatically abolished these morphological defects.Moreover,cathD knockdown also led to dendritic defects in the adult mushroom bodies,suggesting that cathD-mediated processes are required in both the peripheral and central nervous systems.Taken together,our results demonstrate a critical role of cathD in shaping dendritic architecture independent of its proteolytic function.Ting Zhang Daxiao Cheng Cunjin Wu Xingyue Wang Qiang Ke Huifang Lou Liya Zhu Xiao-Dong Wang Shumin Duan Yi-Jun Liu 2020Neuroscience Bulletin2020,36,10:1
17Pathological Networks Involving Dysmorphic Neurons in Type ⅡFocal Cortical Dysplasia显示文摘Focal cortical dysplasia(FCD)is one of the most common causes of drug-resistant epilepsy.Dysmorphic neurons are the major histopathological feature of typeⅡFCD,but their role in seizure genesis in FCD is unclear.Here we performed whole-cell patch-clamp recording and morphological reconstruction of cortical principal neurons in postsurgical brain tissue from drug-resistant epilepsy patients.Quantitative analyses revealed distinct morphological and electrophysiological characteristics of the upper layer dysmorphic neurons in typeⅡFCD,including an enlarged soma,aberrant dendritic arbors,increased current injection for rheobase action potential firing,and reduced action potential firing frequency.Intriguingly,the upper layer dysmorphic neurons received decreased glutamatergic and increased GABAergic synaptic inputs that were coupled with upregulation of the Na^(+)-K^(+)-Cl^(−)cotransporter.In addition,we found a depolarizing shift of the GABA reversal potential in the CamKⅡ-cre::PTENflox/flox mouse model of drug-resistant epilepsy,suggesting that enhanced GABAergic inputs might depolarize dysmorphic neurons.Thus,imbalance of synaptic excitation and inhibition of dysmorphic neurons may contribute to seizure genesis in typeⅡFCD.Yijie Shao Qianqian Ge Jiachao Yang Mi Wang Yu Zhou Jin-Xin Guo Mengyue Zhu Jiachen Shi Yiqi Hu Li Shen Zhong Chen Xiao-Ming Li Jun-Ming Zhu Jianmin Zhang Shumin Duan Jiadong Chen 2022Neuroscience Bulletin2022,38,9:1
18Suggestion on further strengthening ultra-low emission standards for PM emission from coal-fired power plants in China显示文摘China has established the largest clean coal-fired power generation system in the world by accomplishing the technological transformation of coal-fired power plants(CFPPs)to achieve ultra-low emission.The potential for further particulate matter(PM)emission reduction to achieve near-zero emission for CFPPs has become a hotspot issue.In this study,PM emission from some ultra-low emission CFPPs adopting advanced air pollutant control technologies in China was reviewed.The results revealed that the average filterable particulate matter(FPM)concentration,measured as the total particulate matter(TPM)according to the current national monitoring standard,was(1.67±0.86)mg/m^(3),which could fully achieve the ultra-low emission standard for key regions(5 mg/m^(3)),but that achieving the near-zero emission standard was difficult(1 mg/m^(3)).However,the condensable particulate matter(CPM),with an average concentration of(1.06±1.28)mg/m^(3),was generally ignored during monitoring,which led to about 38.7%underestimation of the TPM.Even considering both FPM and CPM,the TPM emission from current CFPPs would contribute to less than 5%of atmospheric PM_(2.5) concentrations in the key cities and regions in China.Therefore,further reduction in FPM emission proposed by the near-zero emission plan of CFPPs may have less environmental benefit than emission control of other anthropogenic sources.However,it is suggested that the management of CPM emission should be strengthened,and a national standard for CPM emission monitoring based on the indirect dilution method should be established for CFPPs.Those measurements are helpful for optimal operation of air pollutant control devices and continuously promoting further emission reduction.Jianguo Deng Shumin Wang Jiawei Zhang Yi Zhang Jingkun Jiang Yongzheng Gu Tao Han Lei Feng Jian Gao Lei Duan 2023Journal of Environmental Sciences2023,,1:1

20FTO is a transcriptional repressor to auto-regulate its own gene and potentially associated with homeostasis of body weight显示文摘Fat mass and obesity-associated (FTO) protein is a ferrous ion (Fe^2+)/2-oxoglutarate (2-OG)-dependent demethylase preferentially catalyzing m^6A sites in RNA. The FTO gene is highly expressed in the hypothalamus with fluctuation in response to various nutritional conditions, which is believed to be involved in the control of whole body metabolism. However, the underlying mechanism in response to different nutritional cues remains poorly understood. Here we show that ketogenic diet-derived ketone body β-hydroxybutyrate (BHB) transiently increases FTO expression in both mouse hypothalamus and cultured cells. Interestingly, the FTO protein represses Fto promoter activity, which can be offset by BHB. We then demonstrate that FTO binds to its own gene promoter, and Fe^2+, but not 2-OG, impedes this binding and increases FTO expression. The BHB-induced occupancy of the promoter by FTO influences the assembly of the basal transcriptional machinery. Importantly, a loss-of-function FTO mutant (I367F), which induces a lean phenotype in FTO^I367F mice, exhibits augmented binding and elevated potency to repress the promoter. Furthermore, FTO fails to bind to its own promoter that promotes FTO expression in the hypothalamus of high-fat diet-induced obese and 48-h fasting mice, suggesting a disruption of the stable expression of this gene. Taken together, this study uncovers a new function of FTO as a Fe^(2+)-sensitive transcriptional repressor dictating its own gene switch to form an auto-regulatory loop that may link with the hypothalamic control of body weight.Shu-Jing Liu Hui-Ling Tang Qian He Ping Lu Tao Fu Xu-Ling Xu Tao Su Mei-Mei Gao Shumin Duan Yan Luo Yue-Sheng Long 2019Journal of Molecular Cell Biology2019,11,2:0
