| 1 | The acidic tumor microenvironment: a target for smart cancer nano-theranostics显示文摘The acidic tumor microenvironment(TME), which mainly results from the high glycolytic rate of tumor cells, has been characterized as a hallmark of solid tumors and found to be a pivotal factor participating in tumor progression. Recently, due to the increasing understanding of the acidic TME, it has been shown that the acidic TME could be utilized as a multifaceted target during the design of various pH-responsive nanoscale theranostic platforms for the precise diagnosis and effective treatment of cancers. In this article,we will give a focused overview on the latest progress in utilizing this characteristic acidic TME as the target of nano-theranostics to enable cancer-specific imaging and therapy. The future perspectives in the development of acidic TME-targeting nanomedicine strategies will be discussed afterwards. | Liangzhu Feng Ziliang Dong Danlei Tao Yicheng Zhang Zhuang Liu | 2018 | National Science Review2018，5，2： | 14 |
| 2 | PIKA as an Adjuvant Enhances Specific Humoral and Cellular Immune Responses Following the Vaccination of Mice with HBsAg plus PIKA显示文摘An adjuvant is usually used to enhance the immune response induced by vaccines. The choice of adjuvant or immune enhancer determines the effectiveness of the immune response. Currently, aluminium (Alum, a generic term for salts of aluminium) is the only FDA-approved adjuvant. Alum predominantly induces the differentiation of Th2 cells and thus mediates an antibody immune response. Therefore, there is an urgent need for new adjuvants that enhance not only humoral but also cellular immune responses. In the present study, we demonstrates that PIKA (a stabilized dsRNA) as an adjuvant directly induces the activation and the proliferation of both B and NK cells in vitro. Injection of PIKA into mice results in the production of cytokines in vivo. In addition, the study demonstrates that PIKA promotes the maturation of bone marrow-derived dendritic cells (BMDCs) including up-regulation of the co-stimulatory molecules CD80, CD86 and CD40, and the induction of cytokines such as IL-12p70, IL-12p40 and IL-6. Importantly, after immunization of mice with HBsAg plus PIKA, the presence of PIKA enhances the titers of HBsAg-specific IgG and HBsAg-specific IFN-γ production. These results demonstrate that PIKA as an adjuvant can promote both humoral and cellular immune responses. These might have an implication in applying PIKA as an adjuvant to be used in the design and development of both therapeutic and preventive vaccines, and used in the clinical study. | Erxia Shen Li Li Lietao Li Lianqiang Feng Lin Lu Ziliang Yao Haixiang Lin Changyou Wu | 2007 | Cellular & Molecular Immunology2007，4，2： | 13 |
| 3 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment. | ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，2： | 11 |

| 6 | Two-dimensional metal-organic-framework as a unique theranostic nano-platform for nuclear imaging and chemo-photodynamic cancer therapy显示文摘Nanoscale metal organic frameworks (NMOFs) with porous structure and inherent biodegradability are attractive nanomedicine platforms.In addition to conventional particulate NMOFs,two-dimensional (2D) NMOFs are emerging as a unique type of NMOFs which however have been relatively less explored for nanomedicine applications.Herein,2D NMOFs composed of Zn2+ and tetrakis(4-carboxyphenyl) porphyrin (TCPP) are fabricated and functionalized with polyethylene glycol (PEG).Compared to their particulate counterpart,such 2D NMOFs show greatly increased drug loading capacity and enhanced light-triggered singlet oxygen production,promising for chemotherapy and photodynamic therapy (PDT),respectively.Utilizing the porphyrin structure of TCPP,our 2D NMOFs could be labeled with a diagnostic radioisotope,99mTc,for single photon emission computer tomography (SPECT) imaging,which reveals efficient tumor homing of those 2D NMOFs upon intravenous injection.While offering a remarkable synergistic in vivo antitumor effect for the combined chemo-PDT,such 2D NMOFs show efficient biodegradation and rapid renal clearance.Our work presents the great promise of 2D NMOFs for nanomedicine applications. | Wenjun Zhu Yu Yang Qiutong Jin Yu Chao Longlong Tian Jingjing Liu Ziliang Dong Zhuang Liu | 2019 | Nano Research2019，12，6： | 9 |
| 7 | Nonlinear optical selection rule based on valley-exciton locking in monolayer ws2显示文摘Optical selection rules fundamentally determine the optical transitions between energy states in a variety of physical systems,from hydrogen atoms to bulk crystals such as gallium arsenide.These rules are important for optoelectronic applications such as lasers,energy-dispersive X-ray spectroscopy,and quantum computation.Recently,single-layer transition metal dichalcogenides have been found to exhibit valleys in momentum space with nontrivial Berry curvature and excitons with large binding energy.However,there has been little study of how the unique valley degree of freedom combined with the strong excitonic effect influences the nonlinear optical excitation.Here,we report the discovery of nonlinear optical selection rules in monolayer WS2,an important candidate for visible 2D optoelectronics because of its high quantum yield and large direct bandgap.We experimentally demonstrated this principle for second-harmonic generation and two-photon luminescence(TPL).Moreover,the circularly polarized TPL and the study of its dynamics evince a sub-ps interexciton relaxation(2p R 1s).The discovery of this new optical selection rule in a valleytronic 2D system not only considerably enhances knowledge in this area but also establishes a foundation for the control of optical transitions that will be crucial for valley optoelectronic device applications such as 2D valley-polarized THz sources with 2p–1s transitions,optical switches,and coherent control for quantum computing. | Jun Xiao Ziliang Ye Ying Wang Hanyu Zhu Yuan Wang Xiang Zhang | 2015 | Light(Science & Applications)2015，4，1： | 8 |
| 8 | The Low Energy X-ray telescope (LE) onboard the Insight-HXMT astronomy satellite显示文摘The Low Energy X-ray telescope(LE) is one of the three main instruments of the Insight-Hard X-ray Modulation Telescope(Insight-HXMT). It is equipped with Swept Charge Device(SCD) sensor arrays with a total geometrical area of 384 cm^2 and an energy band from 0.7 to 13 ke V. In order to evaluate the particle induced X-ray background and the cosmic X-ray background simultaneously, LE adopts collimators to define four types of Field Of Views(FOVs), i.e., 1.6°×6°, 4°×6°, 50°-60°×2°-6 oand the blocked ones which block the X-ray by an aluminum cover. LE is constituted of three detector boxes(LEDs) and an electric control box(LEB) and achieves a good energy resolution of 140 e V@5.9 ke V, an excellent time resolution of 0.98 ms, as well as an extremely low pileup(<1%@18000 cts/s). Detailed performance tests and calibration on the ground have been performed,including energy-channel relation, energy response, detection efficiency and time response. | Yong Chen WeiWei Cui Wei Li Juan Wang YuPeng Xu FangJun Lul YuSa Wang TianXiang Chen DaWei Han Wei Hu Yi Zhang Jia Huo YanJi Yang MaoShun Li Bo Lu ZiLiang Zhang TiPei Li ShuangNan Zhang ShaoLin Xiong Shu Zhang RongFeng Xue XiaoFan Zhao Yue Zhu YuXuan Zhu HongWei Liu YiJung Yang Fan Zhang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 8 |
| 9 | Genetic Types and Metallogenic Model for the Polymetallic Copper–Gold Deposits in the Tongling Ore District, Anhui Province, Eastern China显示文摘The Tongling ore district is one of the most economically important ore areas in the Middle–Lower Yangtze River Metallogenic Belt, eastern China. It contains hundreds of polymetallic copper–gold deposits and occurrences. Those deposits are mainly clustered(from west to east) within the Tongguanshan, Shizishan, Xinqiao, Fenghuangshan, and Shatanjiao orefields. Until recently, the majority of these deposits were thought to be skarn-or porphyry–skarn-type deposits; however there have been recent discoveries of numerous vein-type Au, Ag, and Pb-Zn deposits that do not fall into either of these categories. This indicates that there is some uncertainty over this classification. Here, we present the results of several systematic geological studies of representative deposits in the Tongling ore district. From investigation of the ore-controlling structures, lithology of the host rock, mineral assemblages, and the characteristics of the mineralization and alteration within these deposits, three genetic types of deposits(skarn-, porphyry-, and vein-type deposits) have been identified. The spatial and temporal relationships between the orebodies and Yanshanian intrusions combined with the sources of the ore-forming fluids and metals, as well as the geodynamic setting of this ore district, indicate that all three deposit types are genetically related each other and constitute a magmatic–hydrothermal system. This study outlines a model that relates the polymetallic copper–gold porphyry-, skarn-, and vein-type deposits within the Tongling ore district. This model provides a theoretical basis to guide exploration for deep-seated and concealed porphyry-type Cu(–Mo, –Au) deposits as well as shallow vein-type Au, Ag, and Pb–Zn deposits in this area and elsewhere. | FU Zhongyang XU Xiaochun HE Jun FAN Ziliang XIE Qiaoqin DU Jianguo CHEN Fang | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 6 |
| 10 | Effect of a starch-based filter aid on the dewatering of fine clean coal显示文摘The dewatering of fine, flotation cleaned coals from Huaibei and Xuzhou (bituminous) and Yongcheng (anthracite) were studied. The supernatant and filter cake were examined to determine the rate and extent of flocculation and dewatering. A starch-based filter aid was used to increase flocculation and dewatering rates. The filtration constant, K, and compression index, s, of the Yongcheng slurry were measured under various conditions. A designed experiment was performed to determine optimum conditions for dewatering. The results showed that the filter aid enhanced flocculation and coagulation of the fine cleaned coal slurry, enhanced the structure of the filter cake and promoted dewatering of the cake. Moisture content in the cake was reduced to 17% after vacuum filtration. | GONG Guanqun XIE Guangyuan ZHANG Yingjie WANG Ziliang WANG Jin XIE Linghui LUO Zhenfu | 2010 | Mining Science and Technology2010，20，4： | 6 |
| 11 | The enhanced permeability and retention effect based nanomedicine at the site of injury显示文摘The enhanced permeability retention(EPR)effect based nanomedicine has been widely used for tumor targeting during the past decades.Here we unexpectedly observed the similar'EPR effect'at the site of iniury.We found that the temporary dilated and leaky blood vessels caused by the potent vasodilator histamine in response to injury allowed the injected nanoparticles to pass through the vasculature and reached the injured tissue.Our finding shows the potential underline mechanism of'EPR effect'at the injured site.By loading with antibiotics,we further demonstrated a new strategy for prevention of infection at the site of injury. | Yingjun Liu Dongdong Sun Qin Fan Qingle Ma Ziliang Dong Weiwei Tao Huiquan Tao Zhuang Liu Chao Wang | 2020 | Nano Research2020，13，2： | 6 |
| 12 | Frost heave and freezing processes of saturated rock with an open crack under different freezing conditions显示文摘Frost heave experiments on saturated sandstone and tuff with an open crack are conducted under uniform and unidirectional freezing conditions.Frost heave of crack in sandstone with high permeability is more significant under uniform freezing condition than that under unidirectional freezing condition.However,frost heave of crack in tuff with low permeability is more significant under unidirectional freezing condition.To illustrate the reasons for this phenomenon,a numerical model on the freezing processes of saturated rock with an open crack considering the latent heat of pore water and water in crack is proposed and confirmed to be reliable.Numerical results show that a frozen shell that blocks the migration of water in crack to rock develops first in the outer part of the rock before the freezing of water in crack under unifonn freezing condition.However,the migration path of water in crack to the unfrozen rock under freezing front exists under unidirectional freezing condition.The freezing process and permeability of rock together determine the migration of water in crack and lead to the different frost heave modes of crack for various permeable rocks under different freezing conditions.The frost heave modes of crack in rock with low or high permeability are similar under uniform freezing condition because water migration is blocked by a frozen shell and is irrelevant to rock permeability.For high permeability rock,the frost heave of crack will be weakened due to water migration under unidirectional freezing condition;however,the frost heave of crack would be more significant for low permeability rock because water migration is blocked under unidirectional freezing condition.Therefore,the freezing condition and rock permeability determine the frost heave of rock with crack together,and this should be concerned in cold regions engineering applications. | Zhitao Lv Caichu XIA Yuesong WANG Ziliang LIN | 2020 | Frontiers of Structural and Civil Engineering2020，14，4： | 5 |
| 13 | Bias-drift-free Mach–Zehnder modulators based on a heterogeneous silicon and lithium niobate platform显示文摘Optical modulators have been and will continue to be essential devices for energy-and cost-efficient optical communication networks.Heterogeneous silicon and lithium niobate modulators have demonstrated promising performances of low optical loss,low drive voltage,and large modulation bandwidth.However,DC bias drift is a major drawback of optical modulators using lithium niobate as the active electro-optic material.Here,we demonstrate high-speed and bias-drift-free Mach–Zehnder modulators based on the heterogeneous silicon and lithium niobate platform.The devices combine stable thermo-optic DC biases in silicon and ultra-fast electro-optic modulation in lithium niobate,and exhibit a low insertion loss of 1.8 d B,a low half-wave voltage of 3 V,an electro-optic modulation bandwidth of at least 70 GHz,and modulation data rates up to 128 Gb/s. | SHIHAO SUN MINGBO HE MENGYUE XU SHENGQIAN GAO ZIYAN CHEN XIAN ZHANG ZILIANG RUAN XIONG WU LIDAN ZHOU LIN LIU CHAO LU CHANGJIAN GUO LIU LIU SIYUAN YU XINLUN CAI | 2020 | Photonics Research2020，8，12： | 5 |
| 14 | Preparation of monoclonal antibody based indirect competitive ELISA for detecting 19-nortestosterone residue显示文摘19-Nortestosterone (NT) has been illegally used in horse racing to boost physical performance, and in animal husbandry to accelerate weight gain. To monitor the abuse of NT, our goal was to develop a commercial enzyme linked immunosorbent assay (ELISA) kit. For this purpose, hybridomas were prepared by fusing NS0 mouse myeloma cells with splenocytes isolated from immunized BALB/c mouse. Noncompetitive and competitive indirect ELISA were used to screen positive cell clones. To optimize the indirect competitive ELISA (icELISA) method, various methanol concentrations in assay buffer were evaluated. Matrix effects in urine and spiking test were also investigated. Finally, five hybridoma cell lines named NT-1, NT-2, NT-3, NT-4 and NT-5 were screened out. The corresponding monoclonal antibodies (mAbs) were of the IgG 1 isotype with a k light chain, and the antibody affinity of all mAbs were between 2.6×10 9 and 4.7×10 9 L/mol. The titer and IC 50 values of purified ascites were in the range of 0.64×10 5 2.56×10 5 and 0.55-1.0 ng/mL, respectively. Based on the NT-1 hybridoma, a heterologous icELISA method was developed for the quantitative detection of NT in cattle urine. The dynamic range was from 0.004 to 85.8 ng/mL, with a detection limit for the assay and IC 50 values of 0.002 and 0.55 ng/mL, respectively. Except for a high cross-reactivity (62%) to α-NT, negligible cross-reactivity to other compounds was observed. After optimization, 10% of methanol was used in the assay buffer, and a 20-fold dilution in cattle urine gave an inhibition curve almost the same as that in phosphate buffered saline. The correlation coefficient between the established icELISA and LC-MS/MS method was 0.9871. The results showed that the established heterologous icELISA method provides an excellent alternative for the detection of NT residues in food producing animals. | JIANG JinQing ZHANG HaiTang FAN GuoYing MA JinYou WANG ZiLiang WANG JianHua | 2011 | Chinese Science Bulletin2011，56，25： | 4 |
| 15 | A Monte Carlo Neural Fictitious Self-Play approach to approximate Nash Equilibrium in imperfect-information dynamic games显示文摘Solving the optimization problem to approach a Nash Equilibrium point plays an important role in imperfect information games,e.g.,StarCraft and poker.Neural Fictitious Self-Play(NFSP)is an effective algorithm that learns approximate Nash Equilibrium of imperfect-information games from purely self-play without prior domain knowledge.However,it needs to train a neural network in an off-policy manner to approximate the action values.For games with large search spaces,the training may suffer from unnecessary exploration and sometimes fails to converge.In this paper,we propose a new Neural Fictitious Self-Play algorithm that combines Monte Carlo tree search with NFSP,called MC-NFSP,to improve the performance in real-time zero-sum imperfect-information games.With experiments and empirical analysis,we demonstrate that the proposed MC-NFSP algorithm can approximate Nash Equilibrium in games with large-scale search depth while the NFSP can not.Furthermore,we develop an Asynchronous Neural Fictitious Self-Play framework(ANFSP).It uses asynchronous and parallel architecture to collect game experience and improve both the training efficiency and policy quality.The experiments with th e games with hidden state information(Texas Hold^m),and the FPS(firstperson shooter)games demonstrate effectiveness of our algorithms. | Li ZHANG Yuxuan CHEN Wei WANG Ziliang HAN Shijian Li Zhijie PAN Gang PAN | 2021 | Frontiers of Computer Science2021，15，5： | 3 |
| 16 | Porous Carbon Architecture Assembled by Cross-Linked Carbon Leaves with Implanted Atomic Cobalt for High-Performance Li-S Batteries显示文摘The practical application of lithium-sulfur batteries is severely hampered by the poor conductivity,polysulfide shuttle effect and sluggish reaction kinetics of sulfur cathodes.Herein,a hierarchi-cally porous three-dimension(3D)carbon architecture assembled by cross-linked carbon leaves with implanted atomic Co-N4 has been deli-cately developed as an advanced sulfur host through a SiO_(2)-mediated zeolitic imidazolate framework-L(ZIF-L)strategy.The unique 3D architectures not only provide a highly conductive network for fast electron transfer and buffer the volume change upon lithiation-delithi-ation process but also endow rich interface with full exposure of Co-N4 active sites to boost the lithium polysulfides adsorption and conversion.Owing to the accelerated kinetics and suppressed shuttle effect,the as-prepared sulfur cathode exhibits a superior electrochemical perfor-mance with a high reversible specific capacity of 695 mAh g^(−1) at 5 C and a low capacity fading rate of 0.053%per cycle over 500 cycles at 1 C.This work may provide a promising solution for the design of an advanced sulfur-based cathode toward high-performance Li-S batteries. | Ruirui Wang Renbing Wu Chaofan Ding Ziliang Chen Hongbin Xu Yongfeng Liu Jichao Zhang Yuan Ha Ben Fei Hongge Pan | 2021 | Nano-Micro Letters2021，13，10： | 3 |

| 18 | The Fibrillin-1/VEGFR2/STAT2 signaling axis promotes chemoresistance via modulating glycolysis and angiogenesis in ovarian cancer organoids and cells显示文摘Background:Chemotherapy resistance is a primary reason of ovarian cancer therapy failure;hence it is important to investigate the underlying mechanisms of chemotherapy resistance and develop novel potential therapeutic targets.Methods:RNA sequencing of cisplatin-resistant and sensitive(chemoresis-tant and chemosensitive,respectively)ovarian cancer organoids was performed,followed by detection of the expression level of fibrillin-1(FBN1)in organoids and clinical specimens of ovarian cancer.Subsequently,glucose metabolism,angiogenesis,and chemosensitivity were analyzed in structural glycoprotein FBNl-knockout cisplatin-resistant ovarian cancer organoids and cell lines.To gain insights into the specific functions and mechanisms of action of FBN1 in ovarian cancer,immunoprecipitation,silver nitrate staining,mass spectrometry,immunofluorescence,Western blotting,and Forister resonance energy transfer-fluorescence lifetime imaging analyses were performed,followed by in vivo assays using vertebrate model systems of nude mice and zebrafish.Results:FBN1 expression was significantly enhanced in cisplatin-resistant ovar-ian cancer organoids and tissues,indicating that FBNI might be a key factor in chemoresistance of ovarian cancer.We also discovered that FBN1 sustained the energy stress and induced angiogenesis in vitro and in vivo,which promoted the cisplatin-resistance of ovarian cancer.Knockout of FBN1 combined with treat-ment of the antiangiogenic drug apatinib improved the cisplatin-sensitivity of ovarian cancer cells.Mechanistically,FBN1 mediated the phosphorylation of vascular endothelial growth factor receptor 2(VEGFR2)at the Tyrl054 residue,which activated its downstream focal adhesion kinase(FAK)/protein kinase B(PKB or AKT)pathway,induced the phosphorylation of signal transducer and activator of transcription 2(STAT2)at the tyrosine residue 690(Tyr690),pro-moted the nuclear translocation of STAT2,and ultimately altered the expression of genes associated with STAT2-mediated angiogenesis and glycolysis.Conclusions:The FBN1/VEGFR2/STAT2 signaling axis may induce chemore-sistance of ovarian cancer cells by participating in the process of glycolysis and angiogenesis.The present study suggested a novel FBNl-targeted therapy and/or combination of FBN1 inhibition and antiangiogenic drug for treating ovarian cancer. | Ziliang Wang Wei Chen Ling Zuo Midie Xu Yong Wu Jiami Huang Xu Zhang Yongheng Li Jing Wang Jing Chen Husheng Wang Huizhen Sun | 2022 | Cancer Communications2022，42，3： | 3 |
| 19 | Mercury in soil,vegetable and human hair in a typical mining area in China:Implication for human exposure显示文摘Concentrations of total mercury(T-Hg) and methylmercury(MeHg) in soil, vegetables, and human hair were measured in a mercury mining area in central China. T-Hg and MeHg concentrations in soil ranged from 1.53 to 1054.97 mg/kg and 0.88 to 46.52 μg/kg, respectively.T-Hg concentrations was correlated with total organic carbon(TOC) content(R^2= 0.50, p<0.01)and pH values(R^2= 0.21, p<0.05). A significant linear relationship was observed between MeHg concentrations and the abundance of sulfate-reducing bacteria(SRB)(R^2= 0.39, p<0.05) in soil.Soil incubation experiments amended with specific microbial stimulants and inhibitors showed that Hg methylation was derived from SRB activity. T-Hg and MeHg concentrations in vegetables were 24.79 – 781.02 μg/kg and 0.01 – 0.18 μg/kg, respectively; levels in the edible parts were significantly higher than in the roots(T-Hg: p<0.05; MeHg: p<0.01). Hg species concentrations in rhizosphere soil were positively correlated to those in vegetables(p<0.01), indicating that soil was an important source of Hg in vegetables. Risk assessment indicated that the consumption of vegetables could result in higher probable daily intake(PDI) of T-Hg than the provisional tolerable daily intake(PTDI) for both adults and children. In contrast, the PDI of MeHg was lower than the reference dose. T-Hg and MeHg concentrations in hair samples ranged from 1.57 to 12.61 mg/kg and 0.04 to 0.94 mg/kg, respectively, and MeHg concentration in hair positively related to PDI of MeHg via vegetable consumption(R^2= 0.39, p<0.05), suggesting that vegetable may pose health risk to local residents. | Qin Jia Xuemei Zhu Yaqiong Hao Ziliang Yang Qi Wang Haihui Fu Hongjin Yu | 2018 | Journal of Environmental Sciences2018，30，6： | 3 |
| 20 | Evidence from pseudomorphous β-quartz phenocryst for decompression of rock-forming and ore-forming processes in Shapinggou porphyry Mo deposit显示文摘The Shapinggou porphyry molybdenum(Mo) deposit, located in Jinzhai County, Anhui Province, China, is the largest in the Qinling-Dabie Mo Metallogenic Belt. The intrusive rocks in the Shapinggou Mo ore district formed in the Yanshanian can be divided into two stages based on zircon U-Pb dating and geochemical features. This study focuses on the late stage intrusions(quartz syenite and granite porphyry), which are closely genetically related to molybdenum mineralization. Petrographic observations identified two quartz polymorphs in the quartz syenite and granite porphyry, which were derived from the same magmatic sources and similar evolutionary processes. The quartzes were identified as a xenomorphic β-quartz within quartz syenite, while the quartz phenocrysts within the granite porphyry were pseudomorphous b-quartz, characterized by a hexagonal bipyramid crystallography. The pseudomorphous b-quartz phenocrysts within the granite porphyry were altered from b-quartz through phase transformation. These crystals retained b-quartz pseudomorph. Combined with titanium-inzircon thermometry, quartz phase diagrams, and granitic Q-Ab-Or-H_2O phase diagrams, it is suggested that the quartz syenite and granite porphyry were formed under similar magmatic origins, including similar depths and magmatic crystallization temperatures. However, the β-quartz within quartz syenite indicated that the crystallization pressure was greater than 0.7 GPa, while the original b-quartz within the granite porphyry was formed under pressures between 0.4 and 0.7 GPa. The groundmass of the granite porphyry which formed after the phenocryst indicated a crystallizing pressure below 0.05 GPa. This indicates that the granite porphyry was formed under repetitive and rapid decompression. The decompression was significant as it caused the exsolution of the ore-forming fluids, and boiling and material precipitation during the magmatic-fluid process. The volumetric difference during the phase transformation from b-quartz to β-quartz caused extensive fracturing on the granite porphyry body and the wall rocks. As the main ore-transmitting and ore-depositing structures, these fractures benefit the hydrothermal alteration and stockwork-disseminated mineralization of the porphyry deposit. It is considered that the pseudomorphous β-quartz phenocrysts of the porphyritic body are metallogenic indicators within the porphyry deposits. The pseudomorphous β-quartzes therefore provide evidence for the formation of the porphyry deposit within a decompression tectonic setting. | HE Jun XU XiaoChun XIE QiaoQin FAN ZiLiang CHEN TianHu | 2016 | Science China Earth Sciences2016，59，5： | 3 |
