| 3 | Myeloid-specific targeting of Notch ameliorates murine renal fibrosis via reduced infiltration and activation of bone marrowderived macrophage显示文摘Macrophages play critical roles in renal fibrosis.However,macrophages exhibit ontogenic and functional heterogeneities,and which population of macrophages contributes to renal fibrosis and the underlying mechanisms remain unclear.In this study,we genetically targeted Notch signaling by disrupting the transcription factor recombination signal binding protein-JK(RBP-J),to reveal its role in regulation of macrophages during the unilateral ureteral obstruction(UUO)-induced murine renal fibrosis.Myeloid-specific disruption of RBP-J attenuated renal fibrosis with reduced extracellular matrix deposition and myofibroblast activation,as well as attenuated epithelial-mesenchymal transition,likely owing to the reduced expression of TGF-β.Mean while,RBP-J deletion significantly hampered macrophage infiltration and activation in fibrotic kidney,although their proliferation appeared unaltered.By using macrophage clearance experiment,we found that kidney resident macrophages made negligible contribution,but bone marrow(BM)-derived macrophages played a major role in renal fibrogenesis.Further mechanistic analyses showed that Notch blockade reduced monocyte emigration from BM by down-regulating CCR2 expression.Finally,we found that myeloid-specific Notch activation aggravated renal fibrosis,which was mediated by CCR2^+macrophages infiltration.In summary,our data have unveiled that myeloid-specific targeting of Notch could ameliorate renal fibrosis by regulating BM-derived macrophages recruitment and activation,providing a novel strategy for intervention of this disease. | Yali Jiang Yuanyuan Wang Pengfei Ma Dongjie An Junlong Zhao Shiqian Liang Yuchen Ye Yingying Lu Peng Zhang Xiaowei Liu Hua Han Hongyan Qin | 2019 | Protein & Cell2019，10，3： | 10 |
| 4 | Dual-Mode Induction of Tunable Circularly Polarized Luminescence from Chiral Metal-Organic Frameworks显示文摘The general approach for fabricating solid-state materials showing circularly polarized luminescence(CPL)is still in its challenge.In this work,chiral metal-organic frameworks(MOFs)with full-color and white-color circularly polarized light emission are firstly achieved through a host-guest emitter-loading strategy.Chiral zeolitic imidazolate frameworks(ZIFs,a class of MOFs)are fabricated by a facile and simple mixed-ligand coassembly pathway.Meantime,achiral dyes,quantum dots(QDs),and upconversion nanoparticles(UCNPs)are easily loaded into the chiral ZIFs during the synthetic process.Size-matched dyes can be solely encapsulated into the chiral cages of ZIF,resulting in induced CPL and enhanced luminescence efficiency in solid-state ZIF⊃dye composites.Large-sized QDs,after embedding into the gap of the ZIF particles,also exhibited intense CPL activity.Furthermore,through modulating the blending ratio of colored dyes or QDs in chiral ZIFs,white light-emitting ZIFs with circular polarization could be constructed in a solid state.In addition,through loading rare earth element-based upconversion nanoparticles(UCNPs)into chiral ZIFs,upconverted CPL(UC-CPL)could be achieved with a high dissymmetry factor(glum).Thus,various achiral luminophores were endowed with CPL upon coupling with chiral ZIFs,which significantly deepened and enlarged the research scope of the chiroptical materials in a solid state. | Tonghan Zhao Jianlei Han Xue Jin Minghao Zhou Yan Liu Pengfei Duan Minghua Liu | 2020 | Research2020，，1： | 8 |
| 5 | The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |

| 7 | Deep learning in optical metrology:a review显示文摘With the advances in scientific foundations and technological implementations,optical metrology has become versatile problem-solving backbones in manufacturing,fundamental research,and engineering applications,such as quality control,nondestructive testing,experimental mechanics,and biomedicine.In recent years,deep learning,a subfield of machine learning,is emerging as a powerful tool to address problems by learning from data,largely driven by the availability of massive datasets,enhanced computational power,fast data storage,and novel training algorithms for the deep neural network.It is currently promoting increased interests and gaining extensive attention for its utilization in the field of optical metrology.Unlike the traditional,,physics-basedH approach,deep-learning-enabled optical metrology is a kind of,/data-drivenw approach,which has already provided numerous alternative solutions to many challenging problems in this field with better performances.In this review,we present an overview of the current status and the latest progress of deep-learning technologies in the field of optical metrology.We first briefly introduce both traditional image-processing algorithms in optical metrology and the basic concepts of deep learning,followed by a comprehensive review of its applications in various optical metrology tasks,such as fringe denoising,phase retrieval,phase unwrapping,subset correlation,and error compensation.The open challenges faced by the current deep-learning approach in optical metrology are then discussed.Finally,the directions for future research are outlined. | Chao Zuo Jiaming Qian Shijie Feng Wei Yin Yixuan Li Pengfei Fan Jing Han Kemao Qian Qian Chen | 2022 | Light(Science & Applications)2022，11，4： | 7 |
| 8 | Validation and application of water levels derived from Sentinel-3A for the Brahmaputra River显示文摘For the first time ever, this study aims at applying Sentinel-3 A to the Great Brahmaputra River(GBR) and validating water levels derived from this newly-launched altimetry satellite mission. The GBR is divided into three primary parts:(1) a large section of the Yarlung Zangbo River in China, also termed the Upper Brahmaputra River(UBR) in this study, featured by high elevation,complex terrain, narrow river widths(from less than 100 to 400 m), and limited in situ measurements;(2) the Middle Brahmaputra River(MBR) with widths varying from ~400 m to ~1 km;(3) the Lower Brahmaputra River(LBR), dominated by braided channels with wide river channels(up to several kilometers). For the altimetry data, both waveform retracking and hooking effect correction were applied to mitigate the influence caused by land contamination and to improve the accuracy of water level retrievals. Water levels were derived from 41 virtual stations(VSs) across the GBR and different retracking algorithms were compared with in situ data from two gauging stations in the UBR. Time series of altimetry-based water levels were categorized into three types based on the quality: no data(type 1), degraded(type 2), and good(type 3). Results showed that the VSs(type 1) only existed in the mountainous regions, accounting for ~ a half of the total in the UBR. Validation with the gauged water levels showed that the TIC algorithm performed best among all of the retrackers applied, followed by the Ice-1 algorithm. The standard deviation of the difference between the gauged and TIC-derived water levels ranged from 0.41 to 0.76 m among four different VSs(type 3). In addition, the quality of VSs in the LBR was best, followed by the MBR. Our study has demonstrated the capability of Sentinel-3 A in monitoring water levels in the GBR, thereby paving the way for future applications such as discharge estimation and hydrologic/hydrodynamic applications. | HUANG Qi LI XingDong HAN PengFei LONG Di ZHAO FanYu HOU AiZhong | 2019 | Science China(Technological Sciences)2019，62，10： | 6 |
| 9 | S-palmitoylation regulates AMPA receptors trafficking and function: a novel insight into synaptic regulation and therapeutics显示文摘Glutamate acting on AMPA-type ionotropic glutamate receptor(AMPAR) mediates the majority of fast excitatory synaptic transmission in the mammalian central nervous system. Dynamic regulation of AMPAR by post-translational modifications is one of the key elements that allow the nervous system to adapt to environment stimulations. S-palmitoylation, an important lipid modification by post-translational addition of a long-chain fatty acid to a cysteine residue, regulates AMPA receptor trafficking, which dynamically affects multiple fundamental brain functions, such as learning and memory. In vivo, S-palmitoylation is controlled by palmitoyl acyl transferases and palmitoyl thioesterases.In this review, we highlight advances in the mechanisms for dynamic AMPA receptors palmitoylation,and discuss how palmitoylation affects AMPA receptors function at synapses in recent years.Pharmacological regulation of S-palmitoylation may serve as a novel therapeutic strategy for neurobiological diseases. | Jun Han Pengfei Wu Fang Wang Jianguo Chen | 2015 | Acta Pharmaceutica Sinica B2015，5，1： | 6 |
| 10 | An improved modeling of precipitation phase and snow in the Lancang River Basin in Southwest China显示文摘Precipitation phase(e.g., rainfall and snowfall) and snow(e.g., snowpack and snowmelt runoff) in high-mountain regions may largely affect runoff generation, which is critical to water supply, hydropower generation, agricultural irrigation, and ecosystems downstream. Accurately modeling precipitation phase and snow is therefore fundamental to developing a better understanding of hydrological processes for high-mountain regions and their lower reaches. The Lancang River(LR, or the Upper Mekong River)in China, among the most important transboundary rivers originating from the Tibetan Plateau, features active dam construction and complex water resources allocation of various stakeholders in Southeast Asian countries under climate change. This study aims to improve precipitation phase and snow modeling for the LR basin with a hydrological model and multisource remotely sensed data. Results show that joint use of the Moderate Resolution Imaging Spectroradiometer(MODIS) land surface temperature product with high spatial resolution(1 km×1 km) and an air temperature product can more precisely distinguish precipitation phase than air and wet-bulb temperature products in the LR basin. Snowfall and snowmelt were found to be controlled primarily by rainfall and snowfall temperature thresholds in snow modeling. The rainfall and snowfall temperature thresholds derived from the hydrological model through calibration with remotely sensed snowpack at basin scales were considerably lower than those derived from in situ observations. Rainfall and snowfall temperature thresholds derived from in situ observations could lead to the overestimation of snowmelt runoff due mostly to the lack of representation of point-based measurements at basin scales. This study serves as a basis for better modeling and predicting snow for the LR basin and potentially other similar basins globally. | HAN ZhongYing LONG Di HAN PengFei HUANG Qi DU MingDa HOU AiZhong | 2021 | Science China(Technological Sciences)2021，64，7： | 6 |
| 11 | A novel design of 3D carbon host for stable lithium metal anode显示文摘Rational design of porous conductive hosts with high electrical conductivity,large surface area,and adequate interior space is desirable to suppressing dendritic lithium growth and accommodating large volume change of lithium metal anode during the Li plating/stripping process.However,due to the conductive nature of the conductive hosts,Li is easily deposited directly on the top of the hosts,which hinders it from fully functioning.To circumvent the issue,in this study,we designed a novel porous carbon host with a gradient-pore-size structure based on one-dimensional(1D)carbon with different diameters.With this kind of host,stable cycling with high and stable Coulombic efficiency of~98%is achieved at 0.5 mA cm^(−2) with an areal capacity of 1 mAh cm^(−2) over 320 cycles.In contrast,the normal three-dimensional(3D)carbon nanotube host presents a moss-like Li morphology with wildly fluctuating Coulombic efficiency after 100 cycles.The results reveal that the unique gradient-pore-size structure of the 3D conductive host greatly improves the performance of lithium metal batteries. | Hang Liu Jie Di Ping Wang Rui Gao Han Tian Pengfei Ren Qingxi Yuan Wanxia Huang Ruiping Liu Qiang Liu Ming Feng | 2022 | Carbon Energy2022，4，4： | 5 |

| 13 | The Chinese Carbon-Neutral Goal:Challenges and Prospects显示文摘On 22 September 2020,within the backdrop of the COVID-19 global pandemic,China announced its climate goal for peak carbon emissions before 2030 and to reach carbon neutrality before 2060.This carbon-neutral goal is generally considered to cover all anthropogenic greenhouse gases.The planning effort is now in full swing in China,but the pathway to decarbonization is unclear.The needed transition towards non-fossil fuel energy and its impact on China and the world may be more profound than its reform and development over the past 40 years,but the challenges are enormous.Analysis of four representative scenarios shows significant differences in achieving the carbon-neutral goal,particularly the contribution of non-fossil fuel energy sources.The high target values for nuclear,wind,and bioenergy have approached their corresponding resource limitations,with solar energy being the exception,suggesting solar’s critical role.We also found that the near-term policies that allow for a gradual transition,followed by more drastic changes after 2030,can eventually reach the carbon-neutral goal and lead to less of a reduction in cumulative emissions,thus inconsistent with the IPCC 1.5°C scenario.The challenges and prospects are discussed in the historical context of China’s socio-economic reform,globalization,international collaboration,and development. | Ning ZENG Kejun JIANG Pengfei HAN Zeke HAUSFATHER Junji CAO Daniel KIRK-DAVIDOFF Shaukat ALI Sheng ZHOU | 2022 | Advances in Atmospheric Sciences2022，39，8： | 4 |
| 14 | Site-Dependent Osseointegration of Biodegradable High-Purity Magnesium for Orthopedic Implants in Femoral Shaft and Femoral Condyle of New Zealand Rabbits显示文摘Magnesium(Mg) has been widely accepted as osteoconductive biomaterial, but osseointegration of Mg device at different implantation sites is still unclear. In the present study, high-purity magnesium(HP Mg)pins were implanted into femoral shaft and condyle of New Zealand rabbits concurrently. 2, 8, 12 and 16 weeks after surgery, rabbit femurs were harvested for micro-computed tomography(micro-CT) scanning and subsequent histological examinations. HP Mg pins were retrieved for scanning electron microscope and energy dispersive spectrum(SEM/EDS) analyses. HP Mg pins at both implantation sites performed stable corrosion with mineral deposition and bone incorporation on surface. However, difference in distribution of contact osteogenesis centers and biological properties of peri-implant bone tissues was detected between femoral shaft and femoral condyle. In femoral condyle, contact osteogenesis centers originated from both periosteum and cancellous bones and the whole HP Mg pin was encapsuled in trabecular bone at 16 weeks.Meanwhile, bone volume to total bone volume(BV/TV) and bone mineral density(BMD) of peri-implant bone tissues were above those of normal bone tissues. In femoral shaft, contact osteogenesis centers were only from periosteum and direct bone contact was confined in cortical bone, while BV/TV and BMD kept lower than normal. Furthermore, new formation of peri-implant bone tissues was more active in femoral condyle than in femoral shaft at 16 weeks. Therefore, although HP Mg performed good biocompatibility and corrosion behavior in vivo, its bioadaption of osseointegration at different implantations sites should be taken into consideration. Bone metaphysic was suitable for Mg devices where peri-implant bone tissues regenerated rapidly and the biological properties were close to normal bone tissues. | Pengfei Cheng Changli Zhao Pei Han Jiahua Ni Shaoxiang Zhang Xiaonong Zhang Yimin Chai | 2016 | Journal of Materials Science & Technology2016，32，9： | 4 |
| 15 | The influence of rock anisotropy on elliptical-polarization state of inhomogenously refracted P-wave显示文摘This paper discusses the influence of the anisotropy parameters on elliptical-polarization of the inhomogenously refracted P-wave induced at VTI-media interface.For this refracted P-wave,we have derived,the equations of the elliptical-polarization trajectory.Following the elliptical-polarization trajectory,we calculated the effects of the rock anisotropic-parameters on the polarization state,with a Poincare-sphere-like representation,for several varying media parameters.It is noted that the size,shape and initial phase angle of the elliptical-polarization trajectory are all depending the anisotropy media,as well as on the incident-angle.We expect that the findings from this paper would be applied to practical applications of seismic exploration. | Lin Fa Jie Zhao YongLan Han GuoHui Li PengFei Ding MeiShan Zhao | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，4： | 4 |
| 16 | Zinc finger transcription factor Sp7/Osterix acts on bone formation and regulates col10a1a expression in zebrafish显示文摘Sp7/Osterix as a zinc finger transcription factor is expressed specifically in osteoblasts.Embryonic lethality of Sp7 knockout mice,however,has prevented from examining the functions of Sp7 in osteoblast and bone formation in live animals.Here we used TALEN,a versatile genome-editing tool,to generate one zebrafish sp7 mutant line.Homozygous sp7-/- mutant zebrafish are able to survive to adulthood.Alizarin Red staining and Micro-CT analysis showed that sp7-/- larvae and adult fish fail to develop normal opercula,and display curved tail fins and severe craniofacial malformation,while Alcian Blue staining showed no obvious cartilage defects in sp7-/- fish.Quantitative RT-PCR showed that a number of osteoblast markers including spp1,phex,col1 ala,and col1a1 b are significantly down-regulated in sp7-/- fish.Furthermore,col10a1 a,whose ortholog is the cartilage marker in mice,was shown to be a novel downstream gene of Sp7 as an osteoblast marker in zebrafish.Together,these results suggest that Sp7 is required for zebrafish bone development and zebrafish sp7 mutants provide animal models for investigating novel aspects of bone development. | Pengfei Niu Zhaomin Zhong Mingyong Wang Guodong Huang Shuhao Xu Yi HOU Yilin Yan Han Wang | 2017 | Science Bulletin2017，62，3： | 4 |
| 17 | High-purity magnesium pin enhances bone consolidation in distraction osteogenesis via regulating Ptch protein activating Hedgehog-alternative Wnt signaling显示文摘Magnesium alloys are promising biomaterials for orthopedic implants because of their degradability,osteogenic effects,and biocompatibility.Magnesium has been proven to promote distraction osteogenesis.However,its mechanism of promoting distraction osteogenesis is not thoroughly studied.In this work,a high-purity magnesium pin developed and applied in rat femur distraction osteogenesis.Mechanical test,radiological and histological analysis suggested that high-purity magnesium pin can promote distraction osteogenesis and shorten the consolidation time.Further RNA sequencing investigation found that alternative Wnt signaling was activated.In further bioinformatics analysis,it was found that the Hedgehog pathway is the upstream signaling pathway of the alternative Wnt pathway.We found that Ptch protein is a potential target of magnesium and verified by molecular dynamics that magnesium ions can bind to Ptch protein.In conclusion,HP Mg implants have the potential to enhance bone consolidation in the DO application,and this process might be via regulating Ptch protein activating Hedgehog-alternative Wnt signaling. | Musha Hamushan Weijie Cai Yubo Zhang Zun Ren Jiafei Du Shaoxiang Zhang Changli Zhao Pengfei Cheng Xiaonong Zhang Hao Shen Pei Han | 2021 | Bioactive Materials2021，6，6： | 3 |
| 18 | Fabrication of Fe nanocomplex pillared few-layered Ti_(3)C_(2)T_(x)MXene with enhanced rate performance for lithium-ion batteries显示文摘Pillaring technologies have been considered as an effective way to improve lithium storage performance of Ti_(3)C_(2)T_(x)MXene.Nevertheless,the pillared hybrids suffer from sluggish Li^(+)diffusion kinetics and electronic transportation due to the compact multi-layered MXene structure,thus exhibiting inferior rate performance.Herein,the few-layered Ti_(3)O_(2)MXene(f-Ti_(3)C_(2)MXene)which is free from restacking can be prepared quickly based on the NH4^(+)ions method.Besides,Fe nanocomplex pillared few-layered Ti_(3)C_(2)T_(x)(FPTC)heterostructures are fabricated via the intercalation of Fe ions into the interlayer of f-Ti_(3)C_(2)MXene.The f-Ti_(3)C_(2)MXene which is immune to restacking can provide a highly conductive substrate for the rapid transport of Li+ions and electrons and possess adequate electrolyte accessible area.Moreover,f-Ti_(3)C_(2)MXene can efficiently relieve the aggregation,prevent the pulverization and buffer the large volume change of Fe nanocomplex during lithiation/delithiation process,leading to enhanced charge transfer kinetics and excellent structural stability of FPTC composites.Consequently,the FPTC hybrids exhibit a high capacity of 535 mAh·g^(-1)after 150 cycles at 0.5 A·g^(-1)and an enhanced rate performance with 310 mAh·g^(-1)after 850 cycles at 5 A·g^(-1).This strategy is facile,universal and can be extended tofabricate various few-layered MXene-derived hybrids with superior rate capability. | Pengfei Huang Shunlong Zhang Hangjun Ying Wentao Yang Jianli Wang Rongnan Guo Weiqiang Han | 2021 | Nano Research2021，14，4： | 3 |
| 19 | Recover the abnormal positioning,velocity and timing services caused by BDS satellite orbital maneuvers显示文摘The BeiDou Navigation Satellite System(BDS)provides global Positioning,Velocity,And Timing(PVT)services that are widely used in various areas.The BDS satellites frequently need the orbit maneuvers due to various perturbations to keep satellites in their designed positions.During these maneuvers,PVT services may be abnormal if the data from a maneuvering satellite is used.In this paper we developed an approach to recover the abnormal PVT services.By using BDS observations from multiple tracking stations,the orbital errors of a maneuvering satellite can be in real time obtained and corrected,thereby avoiding any influence on the performance of PVT services.The tests show that the average precision of position,velocity and timing services are improved by 0.8 m,0.1 mm/s and 0.16 ns,respectively,using the developed orbital maneuver recovery approach.In addition,the approach can also be used for the orbital maneuver detection and monitoring. | Rui Tu Rui Zhang Pengfei Zhang Junqiang Han Lihong Fan Xiaochun Lu | 2021 | Satellite Navigation2021，2，1： | 3 |
