| 1 | Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits. | Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang | 2022 | National Science Review2022，9，1： | 13 |
| 2 | 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 |
| 3 | Two gap-free reference genomes and a global view of the centromere architecture in rice显示文摘Rice(Oryza sativa),a major staple throughout the world and a model system for plant genomics and breeding,was the first crop genome sequenced almost two decades ago.However,reference genomes for all higher organisms to date contain gaps and missing sequences.Here,we report the assembly and analysis of gap-free reference genome sequences for two elite O.sativa xian/indica rice varieties,Zhenshan 97 and Minghui 63,which are being used as a model system for studying heterosis and yield.Gap-free reference genomes provide the opportunity for a global view of the structure and function of centromeres.We show that all rice centromeric regions share conserved centromere-specific satellite motifs with different copy numbers and structures.In addition,the similarity of CentO repeats in the same chromosome is higher than across chromosomes,supporting a model of local expansion and homogenization.Both genomes have over 395 non-TE genes located in centromere regions,of which∼41%are actively transcribed.Two large structural variants at the end of chromosome 11 affect the copy number of resistance genes between the two genomes.The availability of the two gap-free genomes lays a solid foundation for further understanding genome structure and function in plants and breeding climate-resilient varieties. | Jia-Ming Song Wen-Zhao Xie Shuo Wang Yi-Xiong Guo Dal-Hoe Koo Dave Kudrna Chenbo Gong Yicheng Huang Jia-Wu Feng Wenhui Zhang Yong Zhou Andrea Zuccolo Evan Long Seunghee Lee Jayson Talag Run Zhou Xi-Tong Zhu Daojun Yuan Joshua Udall Weibo Xie Rod AWing Qifa Zhang Jesse Poland Jianwei Zhang Ling-Ling Chen | 2021 | Molecular Plant2021，14，10： | 9 |
| 4 | Physical location of rice Gm-6,Pi-5(t) genes in O.officinalis with BAC-FISH显示文摘A fluorescence in situ hybridization (FISH) procedure was adopted to physically map two rice BAC clones 24E21 and 4F22 linked to Gm-6 and Pi-5(t) in O. offi-cinalis. FISH results showed that the two BAC clones were located at 4L. The percentage distance from the centromere to the hybridization sites was 72 ± 2.62 for 24E21 and 54± 5.43 for 4F22, the detection rates were 52.70% and 61.2%. The results obtained from the BAC and plasmid clones, RG214 and RZ565 of cultivated rice and O. officinalis were the same. This suggested that the markers, RG214 and RZ565 of cultivated rice and O. officinalis were in the same BAC clones. The homologous sequences of Gm-6 and Pi-5(t) in O. officinalis were positions that signals existed on the 4L. Many signals were observed when no Cot-1 DNA blocked. This also showed that repetitive sequences were some ho-molgous between cultivated rice and O. officinalis. The identification of chromosome 4 of O. officinalis is based on Jena et al. (1994).

| 5 | Emerging predictors of the response to the blockade of immune checkpoints in cancer therapy显示文摘Checkpoint blockade-based immunotherapy offers new options and powerful weapons for the treatment of cancer,but its efficacy varies greatly among different types of cancer and across individual patients.Thus,the development of the right tools that can be used to identify patients who could benefit from this therapy is of utmost importance in order to maximize the therapeutic benefit,minimize risk of toxicities,and guide combination approaches.Multiple predictors have emerged that are based on checkpoint receptor ligand expression,tumor mutational burden,neoantigen and microsatellite instability,tumor-infiltrating immune cells,and peripheral blood biomarkers.In this review,we discuss the current state and progress of predictors as aids in checkpoint blockadebased immunotherapy in cancer. | Xiaolei Li Wenhui Song Changshun Shao Yufang Shi Weidong Han | 2019 | Cellular & Molecular Immunology2019，16，1： | 5 |
| 6 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |
| 7 | Controlled release of hydrogen by implantation of magnesium induces P53-mediated tumor cells apoptosis显示文摘Hydrogen has been used to suppress tumor growth with considerable efficacy.Inhalation of hydrogen gas and oral ingestion of hydrogen-rich saline are two common systemic routes of hydrogen administration.We have developed a topical delivery method of hydrogen at targeted sites through the degradation of magnesium-based biomaterials.However,the underlying mechanism of hydrogen’s role in cancer treatment remains ambiguous.Here,we investigate the mechanism of tumor cell apoptosis triggered by the hydrogen released from magnesium-based biomaterials.We find that the localized release of hydrogen increases the expression level of P53 tumor suppressor proteins,as demonstrated by the in vitro RNA sequencing and protein expression analysis.Then,the P53 proteins disrupt the membrane potential of mitochondria,activate autophagy,suppress the reactive oxygen species in cancer cells,and finally result in tumor suppression.The anti-tumor efficacy of magnesium-based biomaterials is further validated in vivo by inserting magnesium wire into the subcutaneous tumor in a mouse.We also discovered that the minimal hydrogen concentration from magnesium wires to trigger substantial tumor apoptosis is 91.2μL/mm^(3)per day,which is much lower than that required for hydrogen inhalation.Taken together,these findings reveal the release of H2 from magnesium-based biomaterial exerts its anti-tumoral activity by activating the P53-mediated lysosome-mitochondria apoptosis signaling pathway,which strengthens the therapeutic potential of this biomaterial as localized anti-tumor treatment. | Rui Zan Hao Wang Weijie Cai Jiahua Ni Berengere J.C.Luthringer-Feyerabend Wenhui Wang Hongzhou Peng Weiping Ji Jun Yan Jiazeng Xia Yang Song Xiaonong Zhang | 2022 | Bioactive Materials2022，7，3： | 3 |

| 9 | Improving the mechanical property of dissimilar Al/Mg hybrid friction stir welding joint by PIO-ANN显示文摘Ultrasonic-stationary shoulder assisted friction stir welding(U-SSFSW)is a novel hybrid welding technique,which reveals promising prospect in joining Al/Mg dissimilar alloys.A thorough understanding of U-SSFSW process is imperative for the further application of this technique.Pigeon-inspired optimization(PIO)is a swarm intelligent optimization algorithm and is proposed in mathematical modeling and process optimization by artificial intelligence.In this study,PIO optimized artificial neural network(PIOANN)was firstly established to acquire the relationships between the inputs and output of the Al/Mg welding process by U-SSFSW technique.A reliable PIO-ANN was achieved and the joint with a tensile strength of 161 MPa was acquired under the PIO optimized parameters.This tensile strength is higher than any ever-reported results with the similar welding condition.The joint formation,microstructure,microhardness and fracture behaviors were systemically investigated based on the reported studies and the confirmation experiment of this study to explore the enhancing mechanism of U-SSFSW Al/Mg joint. | Wei Hu Zhongwei Ma Shude Ji Qi Song Mingfei Chen Wenhui Jiang | 2020 | Journal of Materials Science & Technology2020，52，18： | 3 |
| 10 | Topotactically constructed nickel-iron(oxy)hydroxide with abundant in-situ produced high-valent iron species for efficient water oxidation显示文摘The low efficiency of oxygen evolution reaction(OER) is regarded as one of the major roadblocks for metal-air batteries and water electrolysis.Herein,a high-performance OER catalyst of NiFe_(0.2)(oxy)hydroxide(NiFe_(0.2)-O_(x)H_(y)) was developed through topotactic transformation of a Prussian blue analogue in an alkaline solution,which exhibits a low overpotential of only 263 mV to reach a current density of 10 mA cm^(-2) and a small Tafel slope of 35 mV dec-1.Ex-situ/operando Raman spectroscopy results indicated that the phase structure of NiFe_(0.2)-O_(x)H_(y) was irreversibly transformed from the type of α-Ni(OH)_(2) to γ-NiOOH with applying an anodic potential,while ex-situ/operando 57Fe Mossbauer spectroscopic studies evidenced the in-situ production of abundant high-valent iron species under OER conditions,which effectively promoted the OER catalysis.Our work elucidates that the amount of high-valent iron species in-situ produced in the NiFe(oxy)hydroxide has a positive correlation with its water oxidation reaction performance,which further deepens the understanding of the mechanism of NiFe-based electrocatalysts. | Zhichong Kuang Song Liu Xuning Li Meng Wang Xinyi Ren Jie Ding Rile Ge Wenhui Zhou Alexandre IRykov Moulay TSougrati Pierre-Emmanuel Lippens Yanqiang Huang Junhu Wang | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |
| 11 | Customized anterior segment photoacoustic imaging for ophthalmic burn evaluation in vivo显示文摘Photoacoustic imaging has many advantages in ophthalmic application including high-resolution,requirement of no exogenous contrast agent,and noninvasive acquisition of both morphologic and functional information.However,due to the limited depth of focus of the imaging method and large curvature of the eye,it remains a challenge to obtain high quality vascular image of entire anterior segment.Here,we proposed a new method to achieve high quality imaging of anterior segment.The new method applied a curvature imaging strategy based on only one time scanning,and hence is time efficient and more suitable for ophthalmic imaging compared to previously reported methods using similar strategy.A custom-built photoacoustic imaging system was adapted for ophthalmic application and a customized image processing method was developed to quantitatively analyze both morphologic and functional information in vasculature of the anterior segment.The results showed that the new method improved the image quality of anterior segment significantly compared to that of conventional high resolution photoacoustic imaging.More importantly,we applied the new method to study ophthalmic disease in an in vivo mouse model for the first time.The results verified the suitability and advantages of the new method for imaging the entire anterior segment and the numerous potentials of applying it in ophthalmic imaging in future. | Huangxuan Zhao Ke Li Fan Yang Wenhui Zhou Ningbo Chen Liang Song Chuansheng Zheng Zhicheng Liu Chengbo Liu | 2021 | Opto-Electronic Advances2021，4，6： | 2 |
| 12 | An efficient hybrid model for fractured reservoirs显示文摘In this study, an efficient hybrid model is proposed to simulate the fluid flow in the reservoirs with multi-scale fractures, which cannot be easily modeled by neither the continuum models nor the discrete fracture models. In the proposed method, the small fractures are modeled by using an improved Multiple Sub-Region method, which can capture the strongly anisotropy of fracture elements and the effects of border region on the transmissibility and provide more accurate results, on the other hand, the large fractures are modeled explicitly as major fluid conduits by the Embedded Discrete Fracture Model. Then, an efficient numerical algorithm based on the Mimetic Finite Difference method is developed to solve the hybrid method. At the end, several numerical examples are carried out to verify the accuracy and applicability of the proposed numerical model. | YAN Xia HUANG ZhaoQin YAO Jun LI Yang FAN DongYan SONG WenHui | 2016 | Science China(Technological Sciences)2016，59，10： | 2 |
| 13 | Passive shimming based on mixed integer programming for MRI magnet显示文摘A mathematical model based on mixed integer programming is presented in this paper for the passive shimming of magnet in magnetic resonance imaging(MRI) scanner.In this model,the magnetic field inhomogeneity tolerance and the central value of the magnetic field after shimming are programmed together with the volume of each shim piece as the variables,which increases the degree of freedom and guarantees a better solution.The magnetic field inhomogeneity tolerance after shimming with a weighting coefficient and the total volume of shim pieces are both contained in the objective function of the model.By assigning different values to the weighting coefficient in the objective function,different shimming plans with different emphases can be obtained.A simulation test has been carried out on a small permanent magnet with frame structure.Several solutions are given and compared in this paper,which indicates that a practical shimming plan can be obtained quickly by solving this model. | YOU XiaoFei WANG Zheng ZHANG XiaoBing YANG WenHui SONG Tao | 2013 | Science China(Technological Sciences)2013，56，5： | 2 |

| 15 | Mesenteric lymph system constitutes the second route in gut-liver axis and transports metabolism-modulating gut microbial metabolites显示文摘The gut-liver axis denotes the intricate connection and interaction between gut microbiome and liver, in which compositional and functional shifts in gut microbiome affect host metabolism. Hepatic portal vein of the blood circulation system has been thought to be the major route for metabolite transportation in the gut-liver axis, but the existence and importance of other routes remain elusive. Here, we perform metabolome comparison in blood circulation and mesenteric lymph systems and identify significantly shifted metabolites in serum and mesentery. Using cellular assays, we find that the majority of decreased metabolites in lymph system under high-fat diet are effective in alleviating metabolic disorders, indicating a high potential of lymph system in regulating liver metabolism. Among those, a representative metabolite, L-carnitine, reduces diet-induced obesity in mice. Metabolic tracing analysis identifies that L-carnitine is independently transported by the mesenteric lymph system, serving as an example that lymph circulation comprises a second route in the gut-liver axis to modulate liver metabolism. Our study provides new insights into metabolite transportation via mesenteric lymph system in the gut-liver axis, offers an extended scope for the investigations in host-gut microbiota metabolic interactions and potentially new targets in the treatment of metabolic disorders. | Ying Yu Bin Liu Xiaolin Liu Xuan Zhang Wenhui Zhang He Tian Guanghou Shui Wenzhao Wang Moshi Song Jun Wang | 2022 | Journal of Genetics and Genomics2022，49，7： | 1 |
| 16 | Evaluation and prevention of formation damage in offshore sandstone reservoirs in China显示文摘Reduction in water injectivity would be harmful to the waterflood development of offshore sandstone oil reservoirs.In this paper the magnitude of formation damage during water injection was evaluated by analyzing the performance of water injection in the Bohai offshore oilfield,China.Two parameters,permeability reduction and rate of wellhead pressure rise,were proposed to evaluate the formation damage around injection wells.The pressure performance curve could be divided into three stages with different characteristics.Analysis of field data shows that formation damage caused by water injection was severe in some wells in the Bohai offshore oilfield,China.In the laboratory,the content of clay minerals in reservoir rock was analyzed and sensitivity tests(including sensitivity to water, flow rate,alkali,salt and acid)were also conducted.Experimental results show that the reservoir had a strong to medium sensitivity to water(i.e.clay swelling)and a strong to medium sensitivity to flow rate, which may cause formation damage.For formation damage prevention,three injection schemes of clay stabilizer(CS)were studied,i.e.continuous injection of low concentration CS(CI),slug injection of high concentration CS(SI),and slug injection of high concentration CS followed by continuous injection of low concentration CS(SI-CI).Core flooding experiments show that SI-CI is an effective scheme to prevent formation damage and is recommended for the sandstone oil reservoirs in the Bohai offshore oilfield during water injection. | Yang Shenglai Sheng Zhichao Liu Wenhui Song Zhixue Wu Ming Zhang Jianwei | 2008 | Petroleum Science2008，5，4： | 1 |

| 19 | Degradation particles derived from high-purity magnesium inhibit osteogenic differentiation through regulation of macrophage polarization显示文摘Magnesium(Mg)and its alloys have great potential as orthopedic implant candidates,which could release various bioactive substances during degradation.Degradation particles(DPs)are one of the degradation products,but the osteoimmunology effects are still unclear.In this study,the effect of DPs on the polar-ization of macrophages and their release of cytokines was investigated.The results verify that excessive generation of DPs from biodegradable Mg can induce macrophages to realize polarization of proinflamma-tory M1 phenotype.Moreover,macrophages secrete proinflammatory cytokines to inhibit the osteogenic differentiation of rat bone marrow stem cells(rBMSCs).This suggests that the effects of DPs should be considered when evaluating Mg-based implants.DPs continuously produced with the degradation of Mg-based implants may influence osseointegration. | Yu Sun Han Yu Hongzhou Peng Xinbao Kang Zhaoxiang Peng Xieping Dong Wenhui Wang Yang Song Xiaonong Zhang | 2023 | Journal of Materials Science & Technology2023，，8： | 1 |
