1Cycle stability of lithium/garnet/lithium cells with different intermediate layers显示文摘The garnet-type electrolytes such as Ta-doped Li_7La_3Zr_2O_(12)(LLZTO) have been viewed as the promising electrolytes for solid-state lithium batteries, but it exhibits problem of high interfacial resistance(1960 Ω·cm^2) and short circuit when being cycled in Li/LLZTO/Li cells at the current density above 0.5 mA·cm^(-2). Introduction of intermediate layers in between lithium and LLZTO is helpful for decreasing the interfacial resistance and suppressing the growth of lithium dendrites. In this work, three kinds of intermediate layers of Au, Nb and Si with the thickness of 100 nm were prepared. Although the interfacial resistance with the Au layer decreases from 1960 to 32 Ω·cm^2, the cells can only cycle for 0.67 h at 0.5 mA·cm^(-2), related to the Au peeled off from the LLZTO. The Nb layers lead to the initial interfacial resistance of 14 Ω·cm^2, while showing extension of cycle time to 50 h with the increase in interfacial resistance due to the formation of the resistive Li–Nb–O phase. The Si layers induce the interfacial resistance as low as 5 Ω·cm^2 and the cycles as long as 120 h, which is attributed to the improvement in electrical contact between Li and electrolyte as well as the maintenance of conductive interface during cycles.Ning Zhao Rui Fang MingHui He Cheng Chen YiQiu Li ZhiJie Bi Xiang-Xin Guo 2018Rare Metals2018,37,6:7
2Effectiveness of Catch-Up Vaccinations after COVID-19 Containment--China,2020显示文摘Introduction:In the early stages of the coronavirus disease 2019(COVID-19)epidemic in China,the highest level of public health emergency response(Level 1 Response)was launched in all province-level administrative divisions(PLADs)across the country.Provision of vaccination services was selectively suspended due to the physical distancing and gathering restrictions required of Level 1 Response.The purpose of this paper is to evaluate the impact of COVID-19 on vaccination services and the effectiveness of selective vaccination service suspension and catch-up vaccinations in China.Methods:Vaccine doses administered,routine vaccination coverage levels,catch-up vaccine doses administered,and coverage levels after the catch-up campaign were determined from individual vaccination records in sampled clinics,standard routine immunization administrative coverage reports,and catch-up vaccination activity reports submitted by PLADs between October 2019 and October 2020.Results:National Immunization Program(NIP)and non-NIP vaccine doses administered in sampled clinics decreased by 80% and 90%,respectively,compared with doses administered before the COVID-19 pandemic.Coverage with the birth dose of hepatitis B vaccine(HepB1)and the Bacillus Calmette-Guérin vaccine(BCG)—two vaccinations recommended to continue throughout the epidemic due to their timecritical nature—were maintained at over 85%,while coverage of other NIP vaccines decreased to below 60%by February 2020.Catch-up vaccination coverage of the 29 PLADs,excluding Xinjiang and Xizang(Tibet),began in April 2020 and exceeded 90%;Hubei catch-up coverage was 95% by October 2020.Conclusions and Implications for Public Health Practice:The COVID-19 pandemic had a great impact on China’s vaccination services.During the epidemic and time of local transmission of the coronavirus,HepB1,BCG,rabies vaccine for postexposure prophylaxis,and tetanus antitoxin(TAT)for wound prophylaxis were maintained at high levels.Of the 69 million vaccine doses postponed during the time of local transmission of the coronavirus,94% were administered in the catch-up campaign.China’s pandemic immunization practices may provide evidence for other countries’immunization programs.Jing Wu Wenzhou Yu Lei Cao Lingsheng Cao Lance Rodewald Jiakai Ye Yifan Song Li Li Xiaoxue Liu Ning Wen Fuzhen Wang Lixin Hao Yixing Li Hui Zheng Keli Li Chao Ma Dan Wu Yanmin Liu Guomin Zhang Zhijie An Huaqing Wang Zundong Yin 2020China CDC weekly2020,2,50:6
3Traditional Chinese Medicine syndrome elements of male infertility revealed by latent tree model analysis显示文摘OBJECTIVE: To explore the features of Traditional Chinese Medicine(TCM) syndromes in male infertility using computer-based analyses.METHODS: Latent class analysis was used to analyze the TCM syndrome data from 813 patients with male infertility and establish a latent tree model.RESULTS: A latent tree model with a Bayesian information criterion score of-11 263 was created.This model revealed that the characteristics of basic TCM syndromes in patients with male infertility were kidney Yang deficiency, kidney Qi deficiency,spleen Yang deficiency, liver Qi stagnation, Qi stagnation and blood stasis, and dump-heat; moreover,most patients with male infertility had complex syndromes(spleen-kidney Yang deficiency and liver Qi stagnation) rather than simple single syndromes.CONCLUSION: The hidden tree model analysis revealed the objective and quantitative complex relationships between the TCM symptoms of male infertility, and obtained the quantification and objective evidence of TCM syndromes in male infertility.Zhang Zhijie Liu Shaoming Zhang Yueyang Yang Jingzhe Kong Tao Wang Chengli Ning Peng Chen Xiaochao Li Xuesong Jia Yusen Chen Xiaojun 2018Journal of Traditional Chinese Medicine2018,38,6:5
4Nuclear Aurora kinase A switches m^(6)A reader YTHDC1 to enhance an oncogenic RNA splicing of tumor suppressor RBM4显示文摘Aberrant RNA splicing produces alternative isoforms of genes to facilitate tumor progression,yet how this process is regulated by oncogenic signal remains largely unknown.Here,we unveil that non-canonical activation of nuclear AURKA promotes an oncogenic RNA splicing of tumor suppressor RBM4 directed by m^(6)A reader YTHDC1 in lung cancer.Nuclear translocation of AURKA is a prerequisite for RNA aberrant splicing,specifically triggering RBM4 splicing from the full isoform(RBM4-FL)to the short isoform(RBM4-S)in a kinase-independent manner.SiSi Li YangFan Qi JiaChuan Yu YuChao Hao Bin He MengJuan Zhang ZhenWei Dai TongHui Jiang SuYi Li Fang Huang Ning Chen Jing Wang MengYing Yang DaPeng Liang Fan An JinYao Zhao WenJun Fan YuJia Pan ZiQian Deng YuanYuan Luo Tao Guo Fei Peng ZhiJie Hou ChunLi Wang FeiMeng Zheng LingZhi Xu Jie Xu QingPing Wen BiLian Jin Yang Wang Quentin Liu 2022Signal Transduction and Targeted Therapy2022,7,5:4
5POLYMERIZATION OF OCTAMETHYLCYCLOTETRASILOXANE WITH HEXAMETHYLDISILAZYL-LITHIUM AS INITIATOR显示文摘This work focused on the anionic polymerization of octamethylcyclotetrasiloxane (D4, D = Me2SiO2/2) initiated by a new kind of initiator hexamethyldisilazyl-lithium (MMPi). 29Si-NMR spectroscopy and gas chromatography (GC) were used to characterize the polymerization products. The process was accelerated by adding a small amount of high activity monomer D3 and by raising the polymerization temperature. At the end of polymerization more than 95% of the monomer was converted to polymer and only a very small amount ofD4 and D5 remained in the polymers.Zhijie Zhang Ning Zhou Cai-hong Xu Ze-min Xie 2001Chinese Journal of Polymer Science2001,19,1:4
6Detection and Initial Response to a Type 2 Vaccine-Derived Poliovirus—Sichuan Province,China,2019显示文摘What is already known about this topic?After the type 2 strain of the live,attenuated poliovirus vaccine was withdrawn globally in 2016,any identification of a type 2 poliovirus is a Public Health Emergency of International Concern.A vaccinederived type 2 poliovirus(VDPV2)was identified in Sichuan,prompting an urgent,comprehensive investigation and response.What is added by this report?Type 2 monovalent,live,attenuated oral poliovirus vaccine(mOPV2)is being used to respond to the numerous VDPV2 outbreaks seen around the world.In contrast,the response in Sichuan used Sabin strain inactivated poliovirus(sIPV)to stop circulation of the VDPV2.In the 6 months following the vaccination response,there have been no VDPV2s detected in Sichuan,despite extensive search.What are the implications for public health practices?Further search for the VDPV2 must continue in order to determine whether transmission has been stopped.The ongoing investigation and response to the Sichuan VDPV2 is providing evidence to the Global Polio Eradication Initiative on managing VDPV2 outbreaks.Jiushun Zhou Ning Wen Yong Zhang Qi Qi Chunxiang Fan Dongmei Yan Xiaoping Zhu Lixin Hao Shuangli Zhu Yu Liu Xiaozhen Ma Chao Ma Lei Nan Yong Chen Qianli Ma Cheng Wang Kun Deng Lei Cao Ge Shao Xianxiang Ding Hong Yang Zhijie An Lance ERodewald Aiqiang Xu Huaqing Wang Zijian Feng Zundong Yin Xianping Wu Wenbo Xu 2020China CDC weekly2020,2,11:3
7Numerical study on dynamic mechanism of brain volume and shear deformation under blast loading显示文摘Blast-induced traumatic brain injury(b-TBI)is a kind of significant injury to soldiers in the current military conflicts.However,the mechanism of b-TBI has not been well understood,and even there are some contradictory conclusions.It is crucial to reveal the dynamic mechanism of brain volume and shear deformations under blast loading for better understanding of b-TBI.In this paper,the numerical simulation method is adopted to carry out comprehensive and in-depth researches on this issue for the first time.Based on the coupled Eulerian-Lagrangian method,the fluid-structure coupling model of the blast wave and human head is developed to simulate two situations,namely the head subjected to the frontal and lateral impacts.The simulation results are analyzed to obtain the underlying dynamic mechanisms of brain deformation.The brain volume deformation is dominated by the local bending vibration of the skull,and the corresponding frequency for the forehead skull under the frontal impact and the lateral skull faced to the lateral impact is as high as 8 kHz and 5 kHz,respectively.This leads to the high-frequency fluctuation of brain pressure and the large pressure gradient along the skull,totally different from the dynamic response of brain under head collisions.While the brain shear deformation mainly depends on the relative tangential displacement between the skull and brain and the anatomical structure of inner skull,being not related to the brain pressure and its gradient.By further comparing the medical statistics,it is inferred that diffuse axonal injury and brain contusion,the two most common types of b-TBI,are mainly attributed to brain shear deformations.And the von Mises stress can be adopted as the indicator for these two brain injuries.This study can provide theoretical guidance for the diagnosis of b-TBI and the development of protective equipment.Zhijie Li Zhibo Du Xiaochuan You Zhanli Liu Jian Cheng Chengcheng Luo Dongyang Chu Shaowu Ning Yue Kang Ce Yang Zhuo Zhuang 2019Acta Mechanica Sinica2019,35,5:3
8Heterogeneous electrolyte membranes enabling double-side stable interfaces for solid lithium batteries显示文摘The solid polymer electrolyte(SPE) is one of the most promising candidates for building solid lithium batteries with high energy density and safety due to its advantages of flexibility and light-weight.However,the conventional monolayered electrolytes usually exhibit unstable contacts with either high-voltage cathodes or Li-metal anodes during cell operation.Herein,heterogeneous dual-layered electrolyte membranes(HDEMs) consisting of the specific functional polymer matrixes united with the designed solid ceramic fillers are constructed to address the crucial issues of interfacial instability.The electrolyte layers composed of the high-conductivity and oxidation-resistance polyacrylonitrile(PAN) combined with Li_(0.33)La_(0.557)TiO_(3) nanofibers are in contact with the high-voltage cathodes,achieving the compatible interface between the cathodes and the electrolytes.Meanwhile,the electrolyte layers composed of the highstability and dendrite-resistance polyethylene oxide(PEO) with Li_(6.4)La_(3) Zr_(1.4)Ta_(0.6)O_(12) nanoparticles are in contact with the Li-metal anodes,aiming to suppress the dendrite growth,as well as avoid the passivation between the PAN and the Li-metal.Consequently,the solid LiNi_(0.6)Co_(0.2)Mn_(0.2)O2‖Li full cells based on the designed HDEMs show the good rate and cycling performance,i.e.the discharge capacity of 170.1 mAh g^(-1) with a capacity retention of 78.2% after 100 cycles at 0.1 C and 30℃.The results provide an effective strategy to construct the heterogeneous electrolyte membranes with double-side stable electrode/-electrolyte interfaces for the high-voltage and dendrite-free solid lithium batteries.Shuang Mu Weilin Huang Wuhui Sun Ning Zhao Mengyang Jia Zhijie Bi Xiangxin Guo 2021Journal of Energy Chemistry2021,30,9:2
9Embryonic lineage tracing with Procr-CreER marks balanced hematopoietic stem cell fate during entire mouse lifespan显示文摘The functional heterogeneity of hematopoietic stem cells(HSCs) has been comprehensively investigated by single-cell transplantation assay.However,the heterogeneity regarding their physiological contribution remains an open question,especially for those with life-long hematopoietic fate of rigorous selfrenewing and balanced differentiation capacities.In this study,we revealed that Procr expression was detected principally in phenotypical vascular endothelium co-expressing DII4 and CD44 in the midgestation mouse embryos,and could enrich all the HSCs of the embryonic day 11.5(E11.5) aortagonad-mesonephros(AGM) region.We then used a temporally restricted genetic tracing strategy to irreversibly label the Procr-exp res sing cells at E9.5.Interestingly,most labeled mature HSCs in multiple sites(such as AGM) around E11.5 were functionally categorized as lymphomyeloid-balanced HSCs assessed by direct transplantation.Furthermore,the labeled cells contributed to an average of 7.8% of immunophenotypically defined HSCs in E14.5 fetal liver(FL) and 6.9% of leukocytes in peripheral blood(PB) during one-year follow-up.Surprisingly,in aged mice of 24 months,the embryonically tagged cells displayed constant contribution to leukocytes with no bias to myeloid or lymphoid lineages.Altogether,we demonstrated,for the first time,the existence of a subtype of physiologically long-lived balanced HSCs as hypothesized,whose precise embryonic origin and molecular identity await further characterization.Xiaona Zheng Guangyu Zhang Yandong Gong Xiaowei Ning Zhijie Bai Jian He Fan Zhou Yanli Ni Yu Lan Bing Liu 2019Journal of Genetics and Genomics2019,46,10:1

12Oxidative phosphorylation safeguards pluripotency via UDP-N-acetylglucosamine显示文摘Dear Editor,Embryonic stem cells(ESCs)have been assumed to possess immature mitochondria and to favor anaerobic glycolysis over oxidative phosphorylation(OXPHOS)for energy production.This proposition is largely based on the findings that ESCs possess globular mitochondria with blurred cristae,and the facts that ESCs have higher glycolysis activity and lower mitochondrial respiration capacity than somatic cells(Kondoh et al.,2007;Folmes et al.,2011,2012;Zhang et al.,2012;Xu et al.,2013;Ito and Suda,2014;Gu et al.,2016).However,recent studies have shown that mitochondrial autophagy and mitochondrial dynamics are pivotal for ESC self-renewal and pluripotency(Todd et al.,2010;Liu et al.,2016,2020;Wang et al.,2019;Zhong et al.,2019).These studies have raised a fundamental question:what is the contribution and functional mechanism of mitochondrial respiration in pluripotency regulation?Jiani Cao Meng Li Kun Liu Xingxing Shi Ning Sui Yuchen Yao Xiaojing Wang Shiyu Li Yuchang Tian Shaojing Tan Qian Zhao Liang Wang Xiahua Chai Lin Zhang Chong Liu Xing Li Zhijie Chang Dong Li Tongbiao Zhao 2023Protein & Cell2023,14,5:1

14Influence of the Chamfer on the Flexural Properties of Beetle Elytron Plates显示文摘To improve the flexural properties of Beetle Elytron Plates(BEPs)and clarify the effect of the transition arcs(chamfers)between the skins and the trabeculae,the chamfers were set in BEPs,and then the influence of the chamfer on BEPs'mechanical properties was investigated via experimentation and the Finite Elemnent Method simulation(FEM).The results indicate that the influence of the chamfer on the flexural properties and ductility was most obvious in the Trabecular Beetle Elytron Plates(TBEPs),less obvious in the Honeycomb Plates(HPs)and basically no efiect was observed on End-trabecular Beetle Elytron Plates(EBEPs).The chamfer can improve the mechanical stability of EBEPSs.As the chamfer diameter increased in the BEPs,the length of the residual trabecular root on the skin increased when failure occurred in the TBEPs.The crack position in the honeycomb wallsof the HPs gradually shifted from the skin to the center.The EBEPs continued to exhibit oblique cracks.From the perspective of the force characteristics of these BEPs.combined with numerical simulation,the influence mechanism of the chamfer on their flcxural propertics was investigated.Ning Hao Mengye Xu Jinxiang Chen Yiheng Song Zhijie Zhang Yaqin Fu 2021Journal of Bionic Engineering2021,18,1:0

16Waste-Derived Catalysts for Water Electrolysis:Circular Economy-Driven Sustainable Green Hydrogen Energy显示文摘The sustainable production of green hydrogen via water electrolysis necessitates cost-effective electrocatalysts.By following the circular economy principle,the utilization of waste-derived catalysts significantly promotes the sustainable development of green hydrogen energy.Currently,diverse waste-derived catalysts have exhibited excellent catalytic performance toward hydrogen evolution reaction(HER),oxygen evolution reaction(OER),and overall water electrolysis(OWE).Herein,we systematically examine recent achievements in waste-derived electrocatalysts for water electrolysis.The general principles of water electrolysis and design principles of efficient electrocatalysts are discussed,followed by the illustration of current strategies for transforming wastes into electrocatalysts.Then,applications of waste-derived catalysts(i.e.,carbon-based catalysts,transitional metal-based catalysts,and carbon-based heterostructure catalysts)in HER,OER,and OWE are reviewed successively.An emphasis is put on correlating the catalysts’structure-performance relationship.Also,challenges and research directions in this booming field are finally highlighted.This review would provide useful insights into the design,synthesis,and applications of waste-derived electrocatalysts,and thus accelerate the development of the circular economy-driven green hydrogen energy scheme.Zhijie Chen Sining Yun Lan Wu Jiaqi Zhang Xingdong Shi Wei Wei Yiwen Liu Renji Zheng Ning Han Bing-Jie Ni 2023Nano-Micro Letters2023,15,1:0

18Divergent expression of Neurl3 from hemogenic endothelial cells to hematopoietic stem progenitor cells during development显示文摘Prior to the generation of hematopoietic stem cells(HSCs)from the hemogenic endothelial cells(HECs)mainly in the dorsal aorta in midgestational mouse embryos,multiple hematopoietic progenitors including erythro-myeloid progenitors and lymphoid progenitors are generated from yolk sac HECs.These HSCindependent hematopoietic progenitors have recently been identified as major contributors to functional blood cell production until birth.However,little is known about yolk sac HECs.Here,combining integrative analyses of multiple single-cell RNA-sequencing datasets and functional assays,we reveal that Neurl3-EGFP,in addition to marking the continuum throughout the ontogeny of HSCs from HECs,can also serve as a single enrichment marker for yolk sac HECs.Moreover,while yolk sac HECs have much weaker arterial characteristics than either arterial endothelial cells in the yolk sac or HECs within the embryo proper,the lymphoid potential of yolk sac HECs is largely confined to the arterial-biased subpopulation featured by the Unc5b expression.Interestingly,the B lymphoid potential of hematopoietic progenitors,but not for myeloid potentials,is exclusively detected in Neurl3-negative subpopulations in midgestational embryos.Taken together,these findings enhance our understanding of blood birth from yolk sac HECs and provide theoretical basis and candidate reporters for monitoring step-wise hematopoietic differentiation.Xiaowei Ning Junjie Du Yandong Gong Yingpeng Yao Zhijie Bai Yanli Ni Yanyan Li Zongcheng Li Haixin Zhao Jie Zhou Bing Liu Yu Lan Siyuan Hou 2023Journal of Genetics and Genomics2023,50,9:0
19Design of earth-abundant amorphous transition metal-based catalysts for electrooxidation of small molecules:Advances and perspectives显示文摘Electrochemical oxidation of small molecules(e.g.,water,urea,methanol,hydrazine,and glycerol)has gained growing scientific interest in the fields of electrochemical energy conversion/storage and environmental remediation.Designing cost-effective catalysts for the electrooxidation of small molecules(ESM)is thus crucial for improving reaction efficiency.Recently,earth-abundant amorphous transition metal(TM)-based nanomaterials have aroused souring interest owing to their earth-abundance,flexible structures,and excellent electrochemical activities.Hundreds of amorphous TM-based nanomaterials have been designed and used as promising ESM catalysts.Herein,recent advances in the design of amorphous TM-based ESM catalysts are comprehensively reviewed.The features(e.g.,large specific surface area,flexible electronic structure,and facile structure reconstruction)of amorphous TM-based ESM catalysts are first analyzed.Afterward,the design of various TM-based catalysts with advanced strategies(e.g.,nanostructure design,component regulation,heteroatom doping,and heterostructure construction)is fully scrutinized,and the catalysts’structure-performance correlation is emphasized.Future perspectives in the development of cost-effective amorphous TM-based catalysts are then outlined.This review is expected to provide practical strategies for the design of next-generation amorphous electrocatalysts.Zhijie Chen Ning Han Renji Zheng Zijie Ren Wei Wei Bing-Jie Ni 2023SusMat2023,3,3:0
20Cases of Residual Paralysis in an Acute Flaccid Paralysis Surveillance System--China,2001−2010显示文摘Background:China has been polio-free since 2000 and maintains an acute flaccid paralysis(AFP)surveillance system.Residual paralysis(RP)in children with acute flaccid paralysis can be caused by Sabinstrain poliovirus(PV)and non-polio enteroviruses(NPEV).Methods:The national AFP surveillance data was analyzed to describe AFP cases with RP in the mainland of China during 2001 to 2010.Epidemiological patterns and virus detection of AFP cases with RP were described.Results:Annual incidence of AFP with RP among children aged<15 years old ranged between 0.22-0.35 cases per 100,000.The peak age for AFP with RP and PV was 2 to 4 months.Among cases with viral Sabinstrain viral isolates,types Ⅱ and Ⅲ were the most common.A summer season peak in RP cases was similar to cases with NPEV isolated.Conclusions and Implications for Public Health Practice:The first ten years after polio eradication of AFP surveillance data for the occurrence of RP can serve as a baseline rate for poliovirus vaccine changes in the routine immunization system to help detect vaccine safety signals in a timely manner and to support the routine polio immunization program switch in China.Ning Wen Qiru Su Chunxiang Fan Haibo Wang Yong Zhang Lei Cao Wei Xia Zhijie An Huiming Luo 2020China CDC weekly2020,2,50:0
