1Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota.Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng 2019Cell Research2019,29,10:192

5Cryospheric Science: research framework and disciplinary system显示文摘Cryospheric changes and their impacts have received increasing concern, extending the research to include the interactions between earth spheres and the impacts of and social adaptation to cryospheric changes. As a result, Cryospheric Science is rapidly developing. However, the research framework of Cryospheric Science has not completely been set up, and the intension and extension of Cryospheric Science are unclear.Following a literature review, the research framework for Cryospheric Science and the discipline components are analysed in this paper. We consider that Cryospheric Science is an inevitable product of international research on the earth and environmental changes as well as on human sustainable development. It will not only strengthen the linkage between the cryosphere and other earth spheres by deepening traditional research areas, but will also bring more focus on the critical roles of the cryosphere in interactions between earth spheres, and will enhance the relationship between cryospheric change and climate, ecology, hydrology, surface environment and sustainable development. The disciplinary tree of Cryospheric Science is developed following the mainstream of change-impacts adaptation. The disciplines of Cryospheric Science were teased out against characteristics of traditional branches and the developing interdisciplinary branches of cryosphere elements, which will provide reference to Cryospheric Science as it systematically grows to maturity.Dahe Qin Yongjian Ding Cunde Xiao Shichang Kang Jianwen Ren Jianping Yang Shiqiang Zhang 2018National Science Review2018,5,2:42
6Molecular subtyping and genomic profiling expand precision medicine in refractory metastatic triple-negative breast cancer:the FUTURE trial显示文摘Triple-negative breast cancer(TNBC)is a highly heterogeneous disease,and molecular subtyping may result in improved diagnostic precision and targeted therapies.Our previous study classified TNBCs into four subtypes with putative therapeutic targets.Here,we conducted the FUTURE trial(ClinicalTrials.gov identifer:NCT03805399),a phaseⅠb/Ⅱsubtyping-based and genomic biomarker-guided umbrella trial,to evaluate the efficacy of these targets.Patients with refractory metastatic TNBC were enrolled and stratifed by TNBC subtypes and genomic biomarkers,and assigned to one of these seven arms:(A)pyrotinib with capecitabine,(B)androgen receptor inhibitor with CDK4/6 inhibitor,(C)anti PD-1 with nab-paclitaxel,(D)PARP inhibitor included,(E)and(F)anti-VEGFR included,or(G)mTOR inhibitor with nab paclitaxel.The primary end point was the objective response rate(ORR).We enrolled 69 refractory metastatic TNBC patients with a median of three previous lines of therapy(range,1-8).Objective response was achieved in 20(29.0%,95%confidence interval(CI):18.7%-41.2%)of the 69 intention-to-treat(ITT)patients.Our results showed that immunotherapy(arm C),in particular,achieved the highest ORR(52.6%,95%CI:28.9%-75.6%)in the ITT population.Arm E demonstrated favorable ORR(26.1%,95%C:10.2%-48.4%in the ITT population)but with more high grade(23)adverse events.Somatic mutations of TOP2A and CD8 immunohistochemical score may have the potential to predict immunotherapy response in the immunomodulatory subtype of TNBC.In conclusion,the phaseⅠb/ⅡFUTURE trial suggested a new concept for TNBC treatment,demonstrating the clinical beneft of subtyping-based targeted therapy for refractory metastatic TNBC.Yi-Zhou Jiang Yin Liu Yi Xiao Xin Hu Lin Jiang Wen-ia Zuo Ding Ma Jiahan Ding Xiaoyu Zhu Jianjun Zou Claire Verschraegen Daniel G.Stover Virginia Kaklamani Zhong-Hua Wang Zhi-Ming Shao 2021Cell Research2021,31,2:37

8Intelligent and connected vehicles: Current status and future perspectives显示文摘Intelligent connected vehicles(ICVs) are believed to change people's life in the near future by making the transportation safer,cleaner and more comfortable. Although many prototypes of ICVs have been developed to prove the concept of autonomous driving and the feasibility of improving traffic efficiency, there still exists a significant gap before achieving mass production of high-level ICVs. The objective of this study is to present an overview of both the state of the art and future perspectives of key technologies that are needed for future ICVs. It is a challenging task to review all related works and predict their future perspectives, especially for such a complex and interdisciplinary area of research. This article is organized to overview the ICV key technologies by answering three questions: what are the milestones in the history of ICVs; what are the electronic components needed for building an ICV platform; and what are the essential algorithms to enable intelligent driving? To answer the first question, the article has reviewed the history and the development milestones of ICVs. For the second question, the recent technology advances in electrical/electronic architecture, sensors, and actuators are presented. For the third question, the article focuses on the algorithms in decision making, as the perception and control algorithm are covered in the development of sensors and actuators. To achieve correct decision-making, there exist two different approaches: the principle-based approach and data-driven approach. The advantages and limitations of both approaches are explained and analyzed. Currently automotive engineers are concerned more with the vehicle platform technology, whereas the academic researchers prefer to focus on theoretical algorithms. However, only by incorporating elements from both worlds can we accelerate the production of high-level ICVs.YANG DianGe JIANG Kun ZHAO Ding YU ChunLei CAO Zhong XIE ShiChao XIAO ZhongYang JIAO XinYu WANG SiJia ZHANG Kai 2018Science China(Technological Sciences)2018,61,10:31
926mA cm^(-2) J_(sc) from organic solar cells with a low-bandgap nonfullerene acceptor显示文摘Nonfullerene-based organic solar cells(NFOSCs)have received great interest recently due to their higher performance and greater potential compared with fullerene-based solar cells[1].Power conversion efficiencies(PCEs)over 13% have been realized in single-junction NFOSCs[2].Compared with traditional fullerene acceptors,the greatest advantage of nonfullerene acceptors is their stronger light-harvesting capability in the visible andZuo Xiao Xue Jia Dan Li Shizhe Wang Xinjian Geng Feng Liu Junwu Chen Shangfeng Yang Thomas P.Russell Liming Ding 2017Science Bulletin2017,62,22:28
10Molecular Characterization and Expression Analysis of TaZFP15, a C_2H_2-Type Zinc Finger Transcription Factor Gene in Wheat (Triticum aestivum L.)显示文摘Based on sequencing of part clones in a root subtractive cDNA library, an expressed sequence tag (EST) sharing high similarity to a rice C2H2 zinc finger transcription factor (ZFP15) was obtained in wheat. Through bioinformatics approach, the wheat C2H2-type ZFP gene referred to TaZFP15 has been identified and characterized. As a full-length cDNA of 670 bp, TaZFP15 has an open reading frame of 408 bp and encodes a 135-aa polypeptide. TaZFP15 contains two C2H2 zinc finger domains and each one has a conserved motif QALGGH. The typical L-box, generally identified in the C2H2 type transcription factors, has also been found in TaZFP15. Phylogenetic analysis suggested that TaZFP15 shares high similarities with rice ZFP15 (GenBank accession no. AY286473), maize ZFP (GenBank accession no. NM_001159094) and a subset of other zinc-finger transcription factor genes in plant species. The expression of TaZFP15 was up-regulated by starved-Pi stress, showing a pattern to be gradually elevated along with the progression of the Pi-stress in a 23-h treatment regime. Similarly, the transcripts of TaZFP15 in roots were also induced by nitrogen deficiency, and abiotic stresses of drought and salinity. No responses of TaZFP15 were detected in roots to nutrition deficiencies of P, Zn, and Ca, and the external treatment of abscisic acid (ABA). TaZFP15 could be specifically amplified in genome A, B, and D, and without variability in the sequences, suggesting that TaZFP15 has multi-copies in the homologous hexaploid species. Transgenic analysis in tobacco revealed that up-regulation of TaZFP15 could significantly improve plant dry mass accumulation via increasing the plant phosphorus acquisition capacity under Pi-deficiency condition. The results suggested that TaZFP15 is involved in mediation of signal transductions of diverse external stresses.SUN Zhao-hua DING Chang-huan LI Xiao-juan XIAO Kai 2012Journal of Integrative Agriculture2012,11,1:22
11Dendritic Cells Transduced with SOCS1 Gene Exhibit Regulatory DC Properties and Prolong Allograft Survival显示文摘SOCS1 is a key regulator of cytokine signaling and is important for maintaining balance in the immune system. It is thought to participate in negative feedback loops in cytokine signaling and may be an important signal for the regulation of dendritic cell (DC) maturation. However, it remains unclear whether DCs transduced with SOCS1 exhibit characteristics of regulatory DCs and induce allogeneic T-cell hyporesponsiveness. In this study, we constructed adenoviral vector coding SOCS1 (Ad-SOCS1) that can efficiently increase SOCS1 gene expression in bone marrow-derived dendritic cells. DCs transduced with Ad-SOCS1 (DC-SOCS1) expressed low levels of costimulatory and MHC molecules, were resistant to maturation and activation stimulation, induced allogeneic T-cell hyporesponsiveness, and promoted the generation of regulatory-like T cells in vitro. DC-SOCS1 pretreatment significantly prolonged the survival of allografts and led to a substantial increase in the generation of regulatory T cells. Our data suggest that SOCS1 inhibits DC maturation and induces regulatory DC generation, therefore possessing therapeutic potential to prevent rejection in organ transplantation.Hong Fu Shaohua Song Fang Liu Zhijia Ni Xiaoyun Shen Liang Xiao Guoshan Ding Quanxing Wang 2009Cellular & Molecular Immunology2009,6,2:20

13A chlorinated copolymer donor demonstrates a 18.13% power conversion efficiency显示文摘The rapid development of low-bandgap(LBG)nonfullerene acceptors and wide-bandgap(WBG)copolymer donors in recent years has boosted the power conversion efficiency(PCE)of organic solar cells(OSCs)to the 18%level[1−21].The commercialization of OSCs is highly expected.However,critical issues like the cost and the stability also determine whether OSCs can enter the market or not[22].Jianqiang Qin Lixiu Zhang Chuantian Zuo Zuo Xiao Yongbo Yuan Shangfeng Yang Feng Hao Ming Cheng Kuan Sun Qinye Bao Zhengyang Bin Zhiwen Jin and Liming Ding 2021Journal of Semiconductors2021,42,1:19
14Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
15Exploring an Integrative Therapy for Treating COVID-19:A Randomized Controlled Trial显示文摘Objectives:To develop a new Chinese medicine(CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome(ARDS)in COVID-19 patients.Methods:A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized,controlled two-arm trial.The two arms of the trial consist of a control therapy(alpha interferon inhalation,50(x g twice daily;and lopinavir/ritonavir,400 and 100 mg twice daily,respectively)and a testing therapy(control therapy plus Keguan-119.4 g twice daily)by random number table at 1:1 ratio with 24 cases each group.After 2-week treatment,adverse events,time to fever resolution,ARDS development,and lung injury on newly diagnosed COVID-19 patients were assessed.Results:An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events.Based on this result,the study was expanded to include a total of 48 participants(24 cases each arm).The results show that compared with the control arm,the testing arm exhibited a significant improvement in time to fever resolution(P=0.035),and a significant reduction in the development of ARDS(P=0.048).Conclusions:Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.(Trial registration No.NCT 04251871 at www.clinicaltrials.gov).WANG Jia-bo WANG Zhong-xia JING Jing ZHAO Peng DONG Jing-hui ZHOU Yong-feng YANG Guang NIU Ming ZHAO Xu JIANG Tian-jun Bl Jing-feng XU Zhe ZHANG Ping WU Dan BAI Zhao-fang GUO Yu-ming YU Si-miao SUN Yong-qiang ZHANG Zi-teng ZHAN Xiao-yan LI Peng-yan DING Jin-biao ZHAO Peng-fei SONG Xue-ai TANG Jian-yuan HE Dong-chu CHEN Zhu QIN En-qiang WANG Rui-lin XIAO Xiao-he 2020Chinese Journal of Integrative Medicine2020,26,9:18
16Comprehensive metabolomics expands precision medicine for triple-negative breast cancer显示文摘Metabolic reprogramming is a hallmark of cancer.However,systematic characterizations of metabolites in triple-negative breast cancer(TNBC)are still lacking.Our study profiled the polar metabolome and lipidome in 330 TNBC samples and 149 paired normal breast tissues to construct a large metabolomic atlas of TNBC.Combining with previously established transcriptomic and genomic data of the same cohort,we conducted a comprehensive analysis linking TNBC metabolome to genomics.Our study classified TNBCs into three distinct metabolomic subgroups:C1,characterized by the enrichment of ceramides and fatty acids;C2,featured with the upregulation of metabolites related to oxidation reaction and glycosyl transfer;and C3,having the lowest level of metabolic dysregulation.Based on this newly developed metabolomic dataset,we refined previous TNBC transcriptomic subtypes and identified some crucial subtype-specific metabolites as potential therapeutic targets.The transcriptomic luminal androgen receptor(LAR)subtype overlapped with metabolomic C1 subtype.Experiments on patient-derived organoid and xenograft models indicate that targeting sphingosine-1-phosphate(S1P),an intermediate of the ceramide pathway,is a promising therapy for LAR tumors.Moreover,the transcriptomic basal-like immune-suppressed(BLIS)subtype contained two prognostic metabolomic subgroups(C2 and C3),which could be distinguished through machine-learning methods.We show that N-acetyl-aspartyl-glutamate is a crucial tumor-promoting metabolite and potential therapeutic target for high-risk BLIS tumors.Together,our study reveals the clinical significance of TNBC metabolomics,which can not only optimize the transcriptomic subtyping system,but also suggest novel therapeutic targets.This metabolomic dataset can serve as a useful public resource to promote precision treatment of TNBC.Yi Xiao Ding Ma Yun-Song Yang Fan Yang Jia-Han Ding Yue Gong Lin Jiang Li-Ping Ge Song-Yang Wu Qiang Yu Qing Zhang François Bertucci Qiuzhuang Sun Xin Hu Da-Qiang Li Zhi-Ming Shao Yi-Zhou Jiang 2022Cell Research2022,32,5:18

18Thiolactone copolymer donor gifts organic solar cells a 16.72% efficiency显示文摘Since 1995,bulk-heterojunction organic solar cells consisting of one or two organic donors and one or two organic acceptors have been fighting for high power conversion efficiencies(PCEs)and good stability[1].Until recent years,this next-generation photovoltaic technology starts to offer decent PCEs,shedding the light on commercialization,and attracting great attention again[2-14].Compared w让h the continuously emerging highperformance nonfullerene acceptors,high-performance donors are rare.Ji Xiong Ke Jin Yufan Jiang Jianqiang Qin Tan Wang Jinfeng Liu Qishi Liu Haili Peng Xiongfeng Li Anxin Sun Xianyi Meng Lixiu Zhang Ling Liu Wenting Li Zhimin Fang Xue Jia Zuo Xiao Yaqing Feng Xiaotao Zhang Kuan Sun Shangfeng Yang Shengwei Shi Liming Ding 2019Science Bulletin2019,64,21:17
19A carbon-oxygen-bridged ladder-type building block for efficient donor and acceptor materials used in organic solar cells显示文摘A carbon-oxygen-bridged ladder-type donor unit(CO5) was invented and prepared via an ‘‘intramolecular demethanolization cyclization' approach. Its single crystal structure indicates enhanced planarity compared with the carbon-bridged analogue indacenodithiophene(IDT). Owing to the stronger electron-donating capability of CO5 than IDT, CO5-based donor and acceptor materials show narrower bandgaps. A donor-acceptor(D-A) copolymer donor(PCO5TPD) and an A-D-A nonfullerene acceptor(CO5IC) demonstrated higher performance than IDT-based counterparts, PIDTTPD and IDTIC, respectively. The better performance of CO5-based materials results from their stronger light-harvesting capability and higher charge-carrier mobilities.Zuo Xiao Fan Liu Xinjian Geng Jianqi Zhang Shizhe Wang Yujun Xie Zhen Li Huai Yang Yongbo Yuan Liming Ding 2017Science Bulletin2017,62,19:16
20Determination of Seven Major Ginsenosides in Different Parts of Panax quinquefolius L.(American Ginseng) with Different Ages显示文摘Ginsenosides Rg1, Re, Rb1, Rc, Rb2, Rb3, and Rd in different parts of the American ginseng plant were investigated. The extraction process was a pressurized microwave-assisted extraction(PMAE). The seven ginsenosides were separated and determined by high-performance liquid chromatography(HPLC) with a ultraviolet(UV) detector, at 203 nm. The experiment results showed significant variations in the individual ginsenoside contents of the American ginseng in different parts and ages of the plant. The results demonstrated that the leaves, root hairs, and rhizomes of Panax quinquefolius L. contained higher ginsenoside contents, followed by the main roots and stems. The leaves contained dramatically higher levels of ginsenoside Rg1, Rb3, and Rd than the other four parts. Higher contents of Rb1 and Re were present in the main roots, root hairs, and rhizomes. The amount of ginsenoside content in the stems was the lowest. The total content of the seven ginsenosides in main roots, root hairs and rhizomes increased with the age of the plant. In contrast, the ginsenoside contents in the leaves and stems decreased with a year of growth.ZHANG Kun WANG Xiao DING Lan LI Juan QU Chen-ling CHEN Li-gang JIN Hai-yan ZHANG Han-qi 2008Chemical Research in Chinese Universities2008,24,6:15
