| 1 | Inhibition of cyclooxygenase-2 activity in subchondral bone modifies a subtype of osteoarthritis显示文摘Osteoarthritis(OA) causes the destruction of joints. Its pathogenesis is still under investigation, and there is no effective diseasemodifying therapy. Here, we report that elevated cyclooxygenase-2(COX-2) expression in the osteocytes of subchondral bone causes both spontaneous OA and rheumatoid arthritis(RA). The knockout of COX-2 in osteocytes or treatment with a COX-2 inhibitor effectively rescues the structure of subchondral bone and attenuates cartilage degeneration in spontaneous OA(STR/Ort)mice and tumor necrosis factor-α transgenic RA mice. Thus, elevated COX-2 expression in subchondral bone induces both OAassociated and RA-associated joint cartilage degeneration. The inhibition of COX-2 expression can potentially modify joint destruction in patients with arthritis. | Manli Tu Mi Yang Nanxi Yu Gehua Zhen Mei Wan Wenlong Liu Baochao Ji Hairong Ma Qiaoyue Guo Peijian Tong Li Cao Xianghang Luo Xu Cao | 2019 | Bone Research2019，7，3： | 5 |
| 2 | Response of magnetic fields at geosynchronous orbit and on the ground to the sudden changes of IMF B_Z显示文摘The rapid change in the Earth’s magnetosphere caused by solar wind disturbances has been an important part of the solar wind-magnetosphere interaction.However most of the previous studies focused on the perturbation of the Earth’s magnetic field caused by solar wind dynamic pressure changes.In this paper,we studied the response of geosynchronous magnetic field and the magnetic field to the rapid southward turning of interplanetary magnetic field during the interval 1350 1420 UT on 7May 2007.During this event,BZ component of the interplanetary magnetic field decreased from 15 nT to 10 nT within 3 min(1403 1406 UT).The geosynchronous magnetic field measured by three geosynchronous satellites(GOES 10 12)first increased and then decreased.The variations of magnetic field strength in the morning sector(9 10 LT)were much larger than those in the dawn sector(5 LT).Meanwhile,the H components of geomagnetic field on the ground have similar response features but exhibit latitude and LT dependent variations.Compared with H components,the D components do not have regular variations.Although the solar wind dynamical pressure encounters small variations,the magnetic field both in space and on the ground does not display similar variations.Therefore,the increase of geomagnetic field in the dawn sector is caused by the southward turning of IMF(interplanetary magnetic field)BZ.These results will help to better understand the coupling process of geomagnetic filed and interplanetary magnetic field. | DONG YiXuan CAO JinBin LIU WenLong ZHANG Lei LI LiuYuan | 2014 | Science China(Technological Sciences)2014，57，2： | 3 |

| 4 | Clinical data analysis reveals the role of OGR1 (GPR68) in head and neck squamous cancer显示文摘Background:Head and neck squamous cancer(HNSC)frequently occurs in the clinic.Revealing the role of the genes that correlate with cancer cell outgrowth will contribute to potential treatment target identification and tumor inhibition.Methods:The gene expression profiles and gene ontology of the proton-sensing G-protein-coupled receptor OGR1 were analyzed using the TCGA(The Cancer Genome Atlas)database.The effects of sex,age,race,and degree of malignancy on HNSC were investigated,and the survival times of HNSC patients with high or low/medium expression levels of OGR1 were compared.Methylation of the OGR1 promoter CpG sites was also investigated and OGR1-related genes were analyzed using gene set enrichment analysis.Results:OGR1 is overexpressed in HNSC patients.However,compared with the low/median expression group,the high OGR1 expression group did not have different survival rates.The OGR1 expression level differed across sex,age,race,and degree of malignancy,while the methylation of the OGR1 promoter CpG sites was maintained at a similar level.Gene set enrichment analysis revealed that OGR1 was positively correlated with head and neck cancer,cisplatin resistance,hypoxia,angiogenesis,cell migration,and TGF-β.Conclusion:The expression of OGR1 correlated with HNSC progression and survival and thus can serve as a potential treatment target and prognostic marker. | Wenlong Zhang Yong Han Weisha Li Lin Cao Libo Yan Chuan Qin Ran Gao | 2020 | Animal Models and Experimental Medicine2020，3，1： | 2 |
| 5 | Downregulation of HNRNPK in human cancer cells inhibits lung metastasis显示文摘Background: Lung cancer frequently occurs in the clinic, leading to poor prognosis and high mortality. Markers for early diagnosis of lung cancer are scarce, and further potential therapeutic targets are also urgently needed.Method: We established a new mouse model in which the specific gene HNRNPK(heterogeneous nuclear ribonucleoprotein K) was downregulated after administration of doxycycline. The lung metastatic nodules were investigated using bioluminescence imaging, micro-CT, and autopsy quantification.Results: Compared with the short hairpin negative control group, less lung metastatic nodules were formed in the short hairpin RNA group.Conclusion: Downregulation of HNRNPK in cancer cells can inhibit lung metastasis. | Mengyuan Li Wenlong Zhang Xingjiu Yang Hongfei Liu Lin Cao Weisha Li Le Wang Guoxin Zhang Ran Gao | 2019 | Animal Models and Experimental Medicine2019，2，4： | 2 |
| 6 | Case study of small scale polytropic index in the central plasma sheet显示文摘This paper studies the effective polytropic index in the central plasma sheet(CPS) by using the method of Kartalev et al.(2006), which adopts the denoising technique of Haar wavelet to identify the homogeneous MHD Bernoulli integral(MBI) and has been frequently used to study the polytropic relation in the solar wind. We chose the quiet CPS crossing by Cluster C1 during the interval 08:51:00–09:19:00 UT on 03 August 2001. In the central plasma sheet, thermal pressure energy per unit mass is the most important part in MBI, and kinetic energy of fluid motion and electromagnetic energy per unit mass are less important. In the MBI, there are many peaks, which correspond to isothermal or near isothermal processes. The interval lengths of homogenous MBI regions are generally less than 1 min. The polytropic indexes are calculated by linearly fitting the data of lnp and lnn within a 16 s window, which is shifted forward by 8 s step length. Those polytropic indexes with |R|≥0.8(R is the correlation coefficient between lnp and lnn) and p-value≤0.1 in the homogeneous regions are almost all in the range of [0, 1]. The mean and median effective polytropic indexes with high R and low p-value in homogeneous regions are 0.34 and 0.32 respectively, which are much different from the polytropic index obtained by traditional method(?trad=?0.15). This result indicates that the CPS is not uniform even during quiet time and the blanket applications of polytropic law to plasma sheet may return misleading value of polytropic index. The polytropic indexes in homogeneous regions with a high correlation coefficient basically have good regression significance and are thus credible. These results are very important to understand the energy transport in magnetotail in the MHD frame. | PANG XueXia CAO JinBin LIU WenLong MA YuDuan LU HaoYu YANG JunYing LI LiuYuan LIU Xu WANG Jing WANG TieYan YU Jiang | 2015 | Science China Earth Sciences2015，58，11： | 2 |
| 7 | Joint Bearing Mechanism of Coal Pillar and Backfilling Body in Roadway Backfilling Mining Technology显示文摘In the traditional mining technology,the coal resources trapped beneath surface buildings,railways,and water bodies cannot be mined massively,thereby causing the lower coal recovery and dynamic disasters.In order to solve the aforementioned problems,the roadway backfilling mining technology is developed and the joint bearing mechanism of coal pillar and backfilling body is presented in this paper.The mechanical model of bearing system of coal pillar and backfilling body is established,by analyzing the basic characteristics of overlying strata deformation in roadway backfilling mining technology.According to the Ritz method in energy variation principle,the elastic solution expression of coal pillar deformation is deduced in roadway backfilling mining technology.Based on elastic-viscoelastic correspondence principle,combining with the burgers rheological constitutive model and Laplace transform theory,the viscoelastic solution expression of coal pillar deformation is obtained in roadway backfilling mining technology.By analyzing the compressive mechanical property of backfilling body,the time formula required for coal pillar and backfilling body to play the joint bearing function in roadway backfilling mining technology is obtained.The example analysis indicates that the time is 140 days.The results can be treated as an important basis for theoretical research and process design in roadway backfilling mining technology. | Zhengzheng Cao Ping Xu Zhenhua Li Minxia Zhang Yu Zhao Wenlong Shen | 2018 | Computers, Materials & Continua2018，，2： | 2 |
| 8 | Hydrogen Bonding-Assisted Synthesis of Silica/Oxidized Mesocarbon Microbeads Encapsulated in Amorphous Carbon as Stable Anode for Optimized/Enhanced Lithium Storage显示文摘The practical application of silica-based composites as an alternative to commercial graphite anode materials is hampered by their large volumetric expansion,poor conductivity,and low Coulombic efficiency.In this work,a novel silica/oxidized mesocarbon microbead/amorphous carbon(SiO2/O’MCMB/C)hierarchical structure in which SiO2 is sandwiched between spherical graphite and amorphous carbon shell was succes sfully fabricated through hydrogen bonding-assisted self-assembly and post-carbon coating method.The obtained three-layer hierarchical structure effectively accommodates the volumetric expansion of SiO2 and significantly enhances the electronic conductivity of composite materials.Moreover,the outer layer of amorphous carbon effectively increases the diffusion rate of lithium ions and promotes the formation of stable SEI film.As a result,the SiO2/O’MCMB/C composite exhibits superior electrochemical performance with a reversible capacity of 459.5 mA h/g in the first cycle,and the corresponding Coulombic efficiency is 62.8%.After 300 cycles,the capacity climbs to around 600 mA h/g.This synthetic route provides an efficient method for preparing SiO2 supported on graphite with excellent electrochemical performance,which is likely to promote its commercial applications. | Zongjie Cao Huitian Liu Wenlong Huang Peng Chen Yuansheng Liu Yu Yu Zhongqiang Shan Shuxian Meng | 2020 | Transactions of Tianjin University2020，26，1： | 2 |

| 10 | Vertical variations in the bio-optical properties of seawater in the northern South China Sea during summer 2008显示文摘Vertical variability in the bio-optical properties of seawater in the northern South China Sea(NSCS)including inherent optical properties(IOPs)and chlorophyll a concentration(Chl)were studied on the basis of in situ data collected in summer 2008 using an absorption/attenuation spectrophotometer.An empirical model was developed to estimate Chl profiles based on the absorption line height at long wavelengths,with a relative root mean square error of 37.03%.Bio-optical properties exhibited large horizontal and vertical spatial variability.As influenced by coastal upwelling and the Zhujiang River(Pearl River)discharge,both IOPs and Chl exhibited high values in the surface waters of the inner shelf,which tended to decrease with distance offshore.Subsurface maximum layers of IOPs and Chl were observed in the middle and outer shelf regions,along with significantly higher values of attenuation coefficients beneath this layer that rapidly increased towards the bottom.In the open ocean,both IOPs and Chl exhibited consistent variability,with the subsurface maximum layer typically located at34–84 m.Phytoplankton were found to be one of the major components in determining the vertical variability of bio-optical properties,with their vertical dynamics influenced by both physical forcing and light attenuation effects.The depth of the subsurface maximum layer was found to be closely related to the fluctuation of the oceanic thermocline and the depth of the euphotic zone,which also affected the total integrated biomass of the upper ocean.Typically high values of attenuation coefficients observed in the bottom waters of the continental shelf reflected the transport of particulate matter over the bottom boundary layer.Our results reveal large spatial differences in bio-optical profiles in response to complex marine ecodynamics in the NSCS.From the perspective of marine research,high-resolution optical measurements are clearly advantageous over conventional bottle sampling. | Guifen Wang Wen Zhou Zhantang Xu Wenlong Xu Yuezhong Yang Wenxi Cao | 2020 | Acta Oceanologica Sinica2020，39，4： | 1 |
| 11 | Replacing“Alkyl”with“Aryl”for inducing accessible channels to closed pores as plateau-dominated sodium-ion battery anode显示文摘Hard carbons are promising anodes for sodium-ion batteries.However,there is still considerable controversy regarding the sodium storage behaviors in hard carbons,which are mainly attributed to the varied precursors,confused pyrolysis mechanism,and different characterization methods.Herein,benefiting from the flexible molecular structure of polymers,a series of hard carbons with carefully tunedmicrostructures are fabricated by adjusting the ratio of aryl and alkyl groups in the epoxy resins.The results of dynamic mechanical analysis,insitu Fourier transform infrared spectra,and synchronous thermal gravimetricinfrared spectrum-gas chromatography/mass spectrometry reveal that replacing the alkyl with aryl groups in the resin can enhance the crosslink density,inhibit the degradation and rearrangement process,and further lead to a more disordered microstructure.In addition,it is suggested that accessible channels provided by sufficiently wide interlayer spacing are necessary for closed pore filling.The optimized anode delivers a high capacity of 375 mAh/g in half cell with an initial Coulombic efficiency of 80.61%,and an energy density of 252 Wh/kg is attained in full cell.Finally,a reliable relationship among precursor-pyrolysis mechanism-structure-performance is established,and the sodium storagemechanism of“adsorption-insertion-pore filling”iswell proved. | Wenlong Shao Qi Cao Siyang Liu Tianpeng Zhang Zihui Song Ce Song Zhihuan Weng Xigao Jian Fangyuan Hu | 2022 | SusMat2022，2，3： | 1 |
| 12 | Delaminated layered double hydroxide delivers DNA molecules as sandwich nanostructure into cells via a non-endocytic pathway显示文摘Layered double hydroxides(LDHs) are effective molecular carriers in cytological research, gene therapy,and transgenic applications. Herein, we investigated the internalization behavior of the LDH-DNA bioconjugates via a microscopic approach and analyzed the internalization pathway by dissipative particle dynamics(DPD) simulations. We experimentally found that LDH can efficiently carry DNA into the nucleus of cell in BY-2 suspension cells. Furthermore, atomic force microscopy and X-ray diffraction analysis demonstrated that the LDH-DNA bioconjugates mainly exist as a DNA-LDH-DNA sandwich complex,while the LDH-DNA-LDH sandwich complex and DNA-LDH complex cannot be excluded. The DPD simulations further indicated that only the DNA-LDH-DNA sandwich structure could penetrate the plasma membrane(PM), while PM is impermeable to the LDH-DNA-LDH sandwich complex and the DNA-LDH complex. This work provides novel perspective for understanding the membrane penetration mechanism of LDH nano-sheets and new insights into the design of novel molecular delivery systems.ó 2017 Science China Press.

| 13 | Electron-ion collider in China显示文摘Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei.As a future high energy nuclear physics project,an Electron-ion collider in China(EicC)has been proposed.It will be constructed based on an upgraded heavy-ion accelerator,High Intensity heavy-ion Accelerator Facility(HIAF)which is currently under construction,together with a new electron ring.The proposed collider will provide highly polarized electrons(with a po-larization of 80%)and protons(with a polarization of 70%)with variable center of mass energies from 15 to 20 GeV and the luminosity of(2–3)×1033 cm^(−2)·s^(−1).Polarized deuterons and Helium-3,as well as unpolarized ion beams from Carbon to Uranium,will be also available at the EicC.The main foci of the EicC will be precision measurements of the structure of the nucleon in the sea quark region,including 3D tomography of nucleon;the partonic structure of nuclei and the parton interaction with the nuclear environment;the exotic states,especially those with heavy flavor quark contents.In addition,issues fundamental to understanding the origin of mass could be addressed by measurements of heavy quarkonia near-threshold production at the EicC.In order to achieve the above-mentioned physics goals,a hermetical detector system will be constructed with cutting-edge technologies.This document is the result of collective contributions and valuable inputs from experts across the globe.The EicC physics program complements the ongoing scientific programs at the Jefferson Laboratory and the future EIC project in the United States.The success of this project will also advance both nuclear and particle physics as well as accelerator and detector technology in China. | Daniele PAnderle Valerio Bertone Xu Cao Lei Chang Ningbo Chang Gu Chen Xurong Chen Zhuojun Chen Zhufang Cui Lingyun Dai Weitian Deng Minghui Ding Xu Feng Chang Gong Longcheng Gui Feng-Kun Guo Chengdong Han Jun He Tie-Jiun Hou Hongxia Huang Yin Huang KrešImir KumeričKi LPKaptari Demin Li Hengne Li Minxiang Li Xueqian Li Yutie Liang Zuotang Liang Chen Liu Chuan Liu Guoming Liu Jie Liu Liuming Liu Xiang Liu Tianbo Liu Xiaofeng Luo Zhun Lyu Boqiang Ma Fu Ma Jianping Ma Yugang Ma Lijun Mao Cédric Mezrag HervéMoutarde Jialun Ping Sixue Qin Hang Ren Craig DRoberts Juan Rojo Guodong Shen Chao Shi Qintao Song Hao Sun PawełSznajder Enke Wang Fan Wang Qian Wang Rong Wang Ruiru Wang Taofeng Wang Wei Wang Xiaoyu Wang Xiaoyun Wang Jiajun Wu Xinggang Wu Lei Xia Bowen Xiao Guoqing Xiao Ju-Jun Xie Yaping Xie Hongxi Xing Hushan Xu Nu Xu Shusheng Xu Mengshi Yan Wenbiao Yan Wencheng Yan Xinhu Yan Jiancheng Yang Yi-Bo Yang Zhi Yang Deliang Yao Zhihong Ye Peilin Yin C-PYuan Wenlong Zhan Jianhui Zhang Jinlong Zhang Pengming Zhang Yifei Zhang Chao-Hsi Chang Zhenyu Zhang Hongwei Zhao Kuang-Ta Chao Qiang Zhao Yuxiang Zhao Zhengguo Zhao Liang Zheng Jian Zhou Xiang Zhou Xiaorong Zhou Bingsong Zou Liping Zou | 2021 | Frontiers of physics2021，16，6： | 1 |

| 15 | Design and construction of microbial cell factories based on systems biology显示文摘Environmental sustainability is an increasingly important issue in industry.As an environmentally friendly and sustainable way,constructing microbial cell factories to produce all kinds of valuable products has attracted more and more attention.In the process of constructing microbial cell factories,systems biology plays a crucial role.This review summarizes the recent applications of systems biology in the design and construction of microbial cell factories from four perspectives,including functional genes/enzymes discovery,bottleneck pathways identification,strains tolerance improvement and design and construction of synthetic microbial consortia.Systems biology tools can be employed to identify functional genes/enzymes involved in the biosynthetic pathways of products.These discovered genes are introduced into appropriate chassis strains to build engineering microorganisms capable of producing products.Subsequently,systems biology tools are used to identify bottleneck pathways,improve strains tolerance and guide design and construction of synthetic microbial consortia,resulting in increasing the yield of engineered strains and constructing microbial cell factories successfully. | Wenlong Yan Zhibei Cao Mingzhu Ding Yingjin Yuan | 2023 | Synthetic and Systems Biotechnology2023，8，1： | 1 |

| 17 | Antiferromagnetic spintronics: An overview and outlook显示文摘Over the pas few decades,the diversified development of antiferomagnetic spintronics has made antiferomagnets(AFMs)interesting and very useful.After tough challenges,the applications of AFMs in electronic devices have transitioned from focusing on the interface coupling features to achieving the manipulation and detection of AFMs.As AFMs are internally magnetic,taking full use of AFMs for information storage has been the main target of research.In this paper,we provide a comprehensive description of AFM spintronics applications from the interface coupling,read-out operations,and writing manipulations perspective.We examine the early use of AFMs in magnetic recordings and conventional magnetoresistive random-access memory(MRAM),and review the latest mechanisms of the manipulation and detection of AFMs.Finally,based on exchange bias(EB)manipulation,a high-performance EB-MRAM is introduced as the next generation of AFM-based memories,which provides an effective method for read-out and writing of AFMs and opens a new era for AFM spintronics. | Danrong Xionga Yuhao Jiang Kewen Shi Ao Du Yuxuan Yao Zongxia Guo Daoqian Zhu Kaihua Cao Shouzhong Peng Wenlong Cai Dapeng Zhu Weisheng Zhao | 2022 | Fundamental Research2022，2，4： | 1 |
| 18 | Femtosecond laser-assisted switching in perpendicular magnetic tunnel junctions with double-interface free layer显示文摘Perpendicular magnetic tunnel junctions with double-interface free layer(p-DMTJs), which exhibit enhanced tunnel magnetoresistance(TMR) and thermal stability(△) at the nanoscale, have received considerable interest as building blocks for spintronic data storage devices. Heat-assisted magnetic recording(HAMR) techniques have been widely employed in mainstream magnetic storage to enable ultrahigh storage density. However, the data access is achieved by sensing the stray field of the selected magnetic element using a mechanical “read head”, resulting in an unfavorable speed limitation and design complexity. To address this issue, integrating laser-assisted switching with a high-performance magnetic tunnel junction has received interest in spintronic R&D;however, it has not yet been achieved. In this study, we experimentally explored femtosecond(fs) laser-assisted switching in a p-DMTJ device using a direct electrical TMR readout. We demonstrate two reconfigurable switching operations, i.e., binary “write” and unidirectional “reset”, by the interplay of the fs laser and synchronized magnetic field sequence. We further explored the joint effect, and a switching phase diagram was obtained. The effect of the stray field of p-DMTJ, as well as laser helicity,on switching is also discussed. Results show the feasibility of fs laser-assisted writing p-DMTJs, which can pave the way in high-density optospintronic storage applications. | Luding WANG Wenlong CAI Kaihua CAO Kewen SHI Bert KOOPMANS Weisheng ZHAO | 2022 | Science China(Information Sciences)2022，65，4： | 1 |

| 20 | Photonic topological fermi nodal disk in non-Hermitian magnetic plasma显示文摘Topological physics mainly arises as a necessary link between properties of the bulk and the appearance of surface states,and has led to successful discoveries of novel topological surface states in Chern insulators,topological insulators,and topological Fermi arcs in Weyl,Dirac,and Nodal line semimetals owing to their nontrivial bulk topology.In particular,topological phases in non-Hermitian systems have attracted growing interests in recent years.In this work,we predict the emergence of the topologically stable nodal disks where the real part of the eigen frequency is degenerate between two bands in non-ideal magnetohydrodynamics plasma with collision and viscosity dissipations.Each nodal disk possesses continuously distributed topological surface charge density that integrates to unity.It is found that the lossy Fermi arcs at the interface connect to the middle of the projection of the nodal disks.We further show that the emergence,coalescence,and annihilation of the nodal disks can be controlled by plasma parameters and dissipation terms.Our findings contribute to understanding of the linear theory of bulk and surface wave dispersions of non-ideal warm magnetic plasmas from the perspective of topological physics. | Wenhui Wang Wenlong Gao Leifeng Cao Yuanjiang Xiang Shuang Zhang | 2020 | Light(Science & Applications)2020，9，1： | 0 |
