| 1 | A seven-gene-deleted African swine fever virus is safe and effective as a live attenuated vaccine in pigs显示文摘African swine fever(ASF)is a devastating infectious disease in swine that is severely threatening the global pig industry.An efficacious vaccine is urgently required.Here,we used the Chinese ASFV HLJ/18 as a backbone and generated a series of genedeleted viruses.The virulence,immunogenicity,safety,and protective efficacy evaluation in specific-pathogen-free pigs,commercial pigs,and pregnant sows indicated that one virus,namely HLJ/18-7GD,which has seven genes deleted,is fully attenuated in pigs,cannot convert to the virulent strain,and provides complete protection of pigs against lethal ASFV challenge.Our study shows that HLJ/-18-7GD is a safe and effective vaccine against ASFV,and as such is expected to play an important role in controlling the spread of ASFV. | Weiye Chen Dongming Zhao Xijun He Renqiang Liu Zilong Wang Xianfeng Zhang Fang Li Dan Shan Hefeng Chen Jiwen Zhang Lulu Wang Zhiyuan Wen Xijun Wang Yuntao Guan Jinxiong Liu Zhigao Bu | 2020 | Science China(Life Sciences)2020，63，5： | 72 |
| 2 | Crustal velocity structure in the Emeishan large igneous province and evidence of the Permian mantle plume activity显示文摘The Emeishan large igneous province(ELIP) in SW China is interpreted to be associated with an ancient mantle plume. Most of the constraints on the role of mantle plume in the generation of the Emeishan flood basalts were provided by geological and geochemical methods, but the geophysical investigation is very limited. In order to better understand the deep structure and features of ELIP, we have studied the crustal velocity structure using the data acquired from the Lijiang-Panzhihua-Qingzhen wide-angle seismic profile. This profile crosses the three sub-zones of the ELIP(the inner, intermediate, and outer zones), divided based on the differential erosion and uplift of the Maokou limestone. The results provided by the active source seismic experiment demonstrate:(1) The average depth of the crystalline basement along the profile is about 2 km.(2) The middle crust in the Inner Zone is characterized by high-velocity anomalies, with the average velocity of 6.2-6.6 km/s, which is about 0.1– 0.2 km/s higher than the normal one. The velocity of the lower crust in the inner zone is 6.9-7.2 km/s, higher than those observed in the intermediate and outer zones(6.7-7.0 km/s). Relatively low velocity anomalies appear in the upper, middle and lower crusts near the junction of the inner zone and intermediate zone, probably due to the effect of the Xiaojiang fault(XJF).(3) The average velocity of the crust is comparatively low on both sides of XJF, especially on the east side, and the average velocity of the consolidated continental crust is also low there. This may suggest that the XJF extends at least down to 40 km deep, even beyond through the crust.(4) The depth to the Moho discontinuity decrease gradually from 47-53 km in the inner zone, via 42-50 km in the intermediate zone to 38-42 km in the outer zone. In the inner zone, the Moho uplifts locally and the(consolidated) crust is characterized by high-velocity anomalies, which are likely related to intensive magma intrusion and underplating associated with melting of plume head. Overall the crustal velocity structure in the study area recorded the imprint left by the Permian Emeishan mantle plume. | XU Tao ZHANG ZhongJie LIU BaoFeng CHEN Yun ZHANG MingHui TIAN XiaoBo XU YiGang TENG JiWen | 2015 | Science China Earth Sciences2015，58，7： | 36 |

| 4 | Policy Analysis and Development Evaluation of Digital Trade:An International Comparison显示文摘As an extension of traditional trade,digital trade is a new type of trade in the era of the digital economy.In this paper,we first analyze the digital trade-related strategies of eight leading economies through word clouds and dissect China s digital trade-related policies using the word frequency method by sorting through the digital trade-related policy documents of 26 economies and Chinese provinces.We then evaluate the status quo of digital trade development in 111 countries and Chinese provinces by building a digital trade index system to determine the development environment and market potential.The results show that all countries attach great importance to digital technology,data and government guidance in the development of digital trade.The results also reveal that'development,''service'and'construction'are the three most frequently used words in various Chinese documents.The overall level of China s digital trade is at the global vanguard,but is characterized by uneven regional development.In the era of digital trade,traditional international trade theory is also in urgent need of breakthroughs and innovation. | Shuzhong Ma Jiwen Guo Hongsheng Zhang | 2019 | China & World Economy2019，27，3： | 29 |

| 6 | Drug nanoclusters formed in confined nano-cages of CD-MOF: dramatic enhancement of solubility and bioavailability of azilsartan显示文摘Tremendous efforts have been devoted to the enhancement of drug solubility using nanotechnologies, but few of them are capable to produce drug particles with sizes less than a few nanometers. This challenge has been addressed here by using biocompatible versatile γ-cyclodextrin(γ-CD) metal-organic framework(CD-MOF) large molecular cages in which azilsartan(AZL) was successfully confined producing clusters in the nanometer range. This strategy allowed to improve the bioavailability of AZL in Sprague–Dawley rats by 9.7-fold after loading into CD-MOF. The apparent solubility of AZL/CD-MOF was enhanced by 340-fold when compared to the pure drug. Based on molecular modeling, a dual molecular mechanism of nanoclusterization and complexation of AZL inside the CD-MOF cages was proposed, which was confirmed by small angle X-ray scattering(SAXS) and synchrotron radiation-Fourier transform infrared spectroscopy(SR-FTIR) techniques. In a typical cage-like unit of CD-MOF, three molecules of AZL were included by the γ-CD pairs, whilst other three AZL molecules formed a nanocluster inside the 1.7 nm sized cavity surrounded by six γ-CDs. This research demonstrates a dual molecular mechanism of complexation and nanoclusterization in CD-MOF leading to significant improvement in the bioavailability of insoluble drugs. | Yuanzhi He Wei Zhang Tao Guo Guoqing Zhang Wei Qin Liu Zhang Caifen Wang Weifeng Zhu Ming Yang Xiaoxiao Hu Vikramjeet Singh Li Wu Ruxandra Gref Jiwen Zhang | 2019 | Acta Pharmaceutica Sinica B2019，9，1： | 13 |

| 8 | Study on crustal, lithospheric and asthenospheric thickness beneath the Qinghai-Tibet Plateau and its adjacent areas显示文摘Based on the results of pure dispersions of Rayleigh wave tomography in the Qinghai-Tibet Plateau and its adjacent areas, taking S wave velocities from previous linear inversion as the initial model, us-ing the simulated annealing algorithm, a nonlinear simultaneous inversion has been carried out for S wave velocity and thickness of different layers, including the crust, the lithosphere and the astheno-sphere. The results indicate: The crustal thickness shows strong correlation with geology structures sketched by the sutures and major faults. The crust is very thick in the Qinghai-Tibet Plateau, varying from 60 km to 80 km. The lithospheric thickness in the Qinghai-Tibet Plateau is thinner (130―160 km) than its adjacent areas. And two blocks can be recognized, divided by an NNE strike boundary running between 90°E―92°E inside the plateau. Its asthenosphere is relatively thick, varies from 150 km to 230 km, and the thickest area is located in the western Qiangtang. India has a thinner crust (32―38 km), a thicker lithosphere of 190 km and a rather thin asthenosphere of only 60 km. Sichuan and Tarim basins have the crust thickness less than 50 km. Their lithospheres are thicker than the Qinghai-Tibet Plateau, and their asthenospheres are thinner. A discussion has been made on the character and formation mechanism of the typical crust-mantle transition zone in the western Qiangtang block. | ZHANG XueMei SUN RuoMei TENG JiWen | 2007 | Chinese Science Bulletin2007，52，6： | 9 |
| 9 | Prevalent thickening and local thinning of the mantle transition zone beneath the Baikal rift zone and its dynamic implications显示文摘The Baikal rift is the most seismically active continental rift in the world and is significant for studying the dynamics of continental rifts, although its precise dynamic mechanisms remain controversial. We calculated receiver functions (1748) from Global Seismographic Network seismic stations TLY and ULN and stacked receiver functions in different bins. Here we present discontinuities at depths of 410km and 660km and thickness of the mantle transition zone (MTZ) beneath the study area. The MTZ structure shows an obvious thickening (292km) in the Baikal rift zone except for an area of limited thinning (230km), whereas it is basically normal (250km) beneath the Mongolian area, to the southeast of the Baikal rift. Combining these results with previous findings, we propose that the large-scale thickening beneath the Baikal rift zone is likely to be caused by the Mesozoic collision between the Siberian Platform and the Mongolia-North China Block or magmatic intrusion into the lower crust, which would result in crust and lithosphere thickening. Thus, the lower crust becomes eclogitized and consequently detached into the deep mantle because of negative buoyancy. The detachment not only induces asthenosphere upwelling but also accelerates mantle convection of water detached from the subducted slab, which would increase mantle melting, while both processes promote the development of the rift. Our preliminary results indicate that the detachment and the consequent hot upwelling have an important influence on the development of the Baikal rift, and a small-scale mantle upwelling indicated by the located thinning may have destroyed the lithosphere and promoted this development. | SI ShaoKun TIAN XiaoBo ZHANG HongShuang TENG JiWen | 2013 | Science China Earth Sciences2013，56，1： | 6 |

| 12 | Synchrotron radiation-based Fourier-transform infrared spectromicroscopy for characterization of the protein/peptide distribution in single microspheres显示文摘The present study establishes a visualization method for the measurement of the distribution and localization of protein/peptide constituents within a single poly-lactide-co-glycolide(PLGA) microsphere using synchrotron radiation–based Fourier-transform infrared spectromicroscopy(SR-FTIR).The representative infrared wavenumbers specific for protein/peptide(Exenatide) and excipient(PLGA) were identified and chemical maps at the single microsphere level were generated by measuring and plotting the intensity of these specific bands.For quantitative analysis of the distribution within microspheres,Matlab software was used to transform the map file into a 3D matrix and the matrix values specific for the drug and excipient were extracted.Comparison of the normalized SR-FTIR maps of PLGA and Exenatide indicated that PLGA was uniformly distributed,while Exenatide was relatively non-uniformly distributed in the microspheres.In conclusion,SR-FTIR is a rapid,nondestructive and sensitive detection technology to provide the distribution of chemical constituents and functional groups in microparticles and microspheres. | Manli Wang Xiaolong Lu Xianzhen Yin Yajun Tong Weiwei Peng Li Wu Haiyan Li Yan Yang Jingkai Gu Tiqiao Xiao Min Chen Jiwen Zhang | 2015 | Acta Pharmaceutica Sinica B2015，5，3： | 5 |
| 13 | Microbial assembly, interaction, functioning, activity and diversification: a review derived from community compositional data显示文摘Microorganisms play crucial roles in maintaining ecosystem stability. The last two decades have witnessed an upsurge instudies on marine microbial community composition using high-throughput sequencing methods. Extensive mining ofthe compositional data has provided exciting new insights into marine microbial ecology from a number of perspectives.Both deterministic and stochastic processes contribute to microbial community assembly but their relative importance instructuring subcommunities, that are categorized by traits such as abundance, functional type and activity, differs. Throughcorrelation-based network analysis, significant progress has been made in unraveling microbial co-occurrence patterns anddynamics in response to environmental changes. Prediction of ecosystem functioning, based on microbial data, is receivingincreasing attention, as closely related microbes often share similar ecological traits and microbial diversity often exhibitssignificant correlations to ecosystem functioning. The ecosystem functioning is likely executed not by the whole community,but rather by an active fraction of a community, which can be inferred from the marker gene transcription level of communitymembers. Furthermore, the huge amount of microbial community data has significantly expanded the tree of lifeand illuminated microbial phylogenetic divergence and evolutionary history. This review summarizes important findingsin microbial assembly, interaction, functioning, activity and diversification, highlighting the interacting roles of differentaspects, derived from community compositional data. | Jiwen Liu Zhe Meng Xiaoyue Liu Xiao-Hua Zhang | 2019 | Marine Life Science & Technology2019，1，1： | 5 |
| 14 | Diversity of culturable heterotrophic bacteria from the Mariana Trench and their ability to degrade macromolecules显示文摘The Mariana Trench is the deepest location on earth and harbors unique microbial communities as evidenced by 16S rRNA gene amplicon and metagenomic sequencing.Obtaining culturable microorganisms from the Mariana Trench will contribute to a further understanding of hadal biogeochemical processes and act as a unique microbial reservoir with potential applications.Here,825 bacterial strains,identified by 16S rRNA gene sequencing,were isolated from 12 water depths(0-10,400 m)of the Mariana Trench with 2216E and R2A media at 4℃ or 28℃ on four cruises during 2015-2017.These bacteria belong to four phyla,nine classes,27 orders,45 families and 108 genera.Alphaproteobacteria,Gammaproteobacteria,Actinobacteria_c,Bacilli and Flavobacteriia were the most abundant classes,accounting for 37.9%,33.0%,11.8%,8.6%and 8.0%of the total bacterial isolates,respectively.2216E and R2A media were found to have a better selectivity to Bacilli and Flavobacteriia,respectively.Fifty strains were potential novel bacterial species with a 16S rRNA gene similarity<98.65%,and a higher percentage of novel strains were obtained from R2A than 2216E medium.Additionally,301(150 species)out of 354 strains(178 species)selected from each depth could degrade at least one of the ten kinds of macromolecules tested.These results indicate that there is a high diversity of culturable bacteria in the Mariana Trench and they can produce a variety of extracellular enzymes.Our study provides a valuable resource of microorganisms for investigating their biogeochemical roles in the Mariana Trench and for industrial applications. | Xiuxiu Zhao Jiwen Liu Shun Zhou Yanfen Zheng Yanhong Wu Kazuhiro Kogure Xiao-Hua Zhang | 2020 | Marine Life Science & Technology2020，2，2： | 5 |
| 15 | Seismic traveltime inversion of 3D velocity model with triangulated interfaces显示文摘Seismic traveltime tomographic inversion has played an important role in detecting the internal structure of the solid earth. We use a set of blocks to approximate geologically complex media that cannot be well described by layered models or cells. The geological body is described as an aggregate of arbitrarily shaped blocks,which are separated by triangulated interfaces. We can describe the media as homogenous or heterogeneous in each block. We define the velocities at the given rectangle grid points for each block,and the heterogeneous velocities in each block can be calculated by a linear interpolation algorithm. The parameters of the velocity grid positions are independent of the model parameterization,which is advantageous in the joint inversion of the velocities and the node depths of an interface. We implement a segmentally iterative ray tracer to calculate traveltimes in the 3D heterogeneous block models.The damped least squares method is employed in seismic traveltime inversion,which includes the partial derivatives of traveltime with respect to the depths of nodes in the triangulated interfaces and velocities defined in rectangular grids. The numerical tests indicate that the node depths of a triangulated interface and homogeneous velocity distributions can be well inverted in a stratified model. | Fei Li Tao Xu Minghui Zhang Zhenbo Wu Chenglong Wu Zhongjie Zhang Jiwen Teng | 2014 | Earthquake Science2014，27，2： | 5 |
| 16 | Sodium dodecyl sulfate/β-cyclodextrin vesicles embedded in chitosan gel for insulin delivery with p H-selective release显示文摘In an answer to the challenge of enzymatic instability and low oral bioavailability of proteins/peptides, a new type of drug-delivery vesicle has been developed. The preparation, based on sodium dodecyl sulfate(SDS) and β-cyclodextrin(β-CD) embedded in chitosan gel, was used to successfully deliver the model drug-insulin. The self-assembled SDS/β-CD vesicles were prepared and characterized by particle size, zeta potential, appearance, microscopic morphology and entrapment efficiency. In addition, both the interaction of insulin with vesicles and the stability of insulin loaded in vesicles in the presence of pepsin were investigated.The vesicles were crosslinked into thermo-sensitive chitosan/β-glycerol phosphate solution for an in-situ gel to enhance the dilution stability. The in vitro release characteristics of insulin from gels in media at different p H values were investigated. The insulin loaded vesicles–chitosan hydrogel(IVG) improved the dilution stability of the vesicles and provided p H-selective sustained release compared with insulin solution–chitosan hydrogel(ISG). In vitro, IVG exhibited slow release in acidic solution and relatively quick release in neutral solutions to provide drug efficacy. In simulated digestive fluid, IVG showed better sustained release and insulin protection properties compared with ISG. Thus IVG might improve the stability of insulin during its transport in vivo and contribute to the bioavailability and therapeutic effect of insulin. | Zhuo Li Haiyan Li Caifen Wang Jianghui Xu Vikramjeet Singh Dawei Chen Jiwen Zhang | 2016 | Acta Pharmaceutica Sinica B2016，6，4： | 4 |
| 17 | The protective effects of peptides from Chinese baijiu on AAPH-induced oxidative stress in HepG2 cells via Nrf2 signaling pathway显示文摘Antioxidant peptides have been widely reported.However,only a few reports have been published examining the antioxidant peptides derived from Chinese baijiu.In this study,6 novel peptides derived from Chinese baijiu were identified successfully using high-performance liquid chromatography-quadrupoletime-of-flight mass spectrometry(HPLC-QTOF-MS)with a concentration of 0.835–24.540μg/L.The underlying molecular mechanisms were investigated,and their cytoprotective effects were examined against 2,2’-azobis(2-methylpropanimidamidine)dihydrochloride(AAPH)-induced oxidative stress in Hep G2 cells.The results showed that these peptides exerted protective effects by suppressing reactive oxygen species(ROS)generation,preventing malondialdehyde(MDA)formation,and upregulating cellular antioxidant enzyme activities(SOD,CAT,and GSH-Px)in a dose-dependent manner.Further experiments proved that these peptides exerted antioxidant effects via Nrf2/ARE-mediated signaling pathway by promoting Nrf2 nuclear translocation,inhibiting ubiquitination,and enhancing transcription capacity of Nrf2 in Hep G2 cells.These findings provide the molecular basis for the effects of antioxidant peptides derived from Chinese baijiu,which is important for a deeper understanding of the relationship between human health and moderate drinking. | Jiaying Huo Yuezhang Ming Huifeng Li Anjun Li Jiwen Zhao Mingquan Huang Weizheng Sun Jihong Wu Jinglin Zhang | 2022 | Food Science and Human Wellness2022，11，6： | 3 |
| 18 | Optimization of taste-masking on ibuprofen microspheres with selected structure features显示文摘The microsphere was a primary particulate system for taste-masking with unique structural features defined by production process. In this article, ibuprofen lipid microspheres of octadecanol and glycerin monostearate were prepared to mask the undesirable taste of ibuprofen via three kinds of spray congealing processes, namely, air-cooling, water-cooling and citric acid solution-cooling. The stereoscopic and internal structures of ibuprofen microspheres were quantitatively analyzed by synchrotron radiation X-ray micro-computed tomography(SR-μCT) to establish the relationship between the preparation process and microsphere architectures. It was found that the microstructure and morphology of the microspheres were significantly influenced by preparation processes as the primary factors to determine the release profiles and taste-masking effects. The sphericity of ibuprofen microspheres congealed in citric acid solution was higher than that of other two and its morphology was more regular than that being congealed in air or distilled water, and the contact angles between congealing media and melted ibuprofen in octadecanol and glycerin monostearate well demonstrated the structure differences among microspheres of three processes which controlled the release characteristics of the microspheres. The structure parameters like porosity, sphericity, and radius ratio from quantitative analysis were correlated well with drug release behaviors. The results demonstrated that the exterior morphology and internal structure of microspheres had considerable influences on the drug release behaviors as well as taste-masking effects. | Wei Qin Yuanzhi He Zhen Guo Liu Zhang Li Wu Xianzhen Yin Shailendra Shakya Abi Maharjan Yan Tang Weifeng Zhu Jiwen Zhang | 2019 | Asian Journal of Pharmaceutical Sciences2019，14，2： | 3 |

| 20 | Observation and research of deep underground multi-physical fields—Huainan–848 m deep experiment显示文摘Compared with the surface,the deep environment has the advantages of allowing“super-quiet and ultra-clean”-geophysical field observation with low vibration noise and little electromagnetic interference,which are conducive to the realization of long-term and high-precision observation of multi-physical fields,thus enabling the solution of a series of geoscience problems.In the Panyidong Coal Mine,where there are extensive underground tunnels at the depth of 848 m below sea level,we carried out the first deep-underground geophysical observations,including radioactivity,gravity,magnetic,magnetotelluric,background vibration and six-component seismic observations.We concluded from these measurements that(1)the background of deep subsurface gravity noise in the long-period frequency band less than 2 Hz is nearly two orders of magnitude weaker than that in the surface observation environment;(2)the underground electric field is obviously weaker than the surface electric field,and the relatively high frequency of the underground field,greater than 1 Hz,is more than two orders of magnitude weaker than that of the surface electric field;the east-west magnetic field underground is approximately the same as that at the surface;the relatively high-frequency north-south magnetic field underground,below 10 Hz,is at least one order of magnitude lower than that at the surface,showing that the underground has a clean electromagnetic environment;(3)in addition to the highfrequency and single-frequency noises introduced by underground human activities,the deep underground space has a significantly lower background vibration noise than the surface,which is very beneficial to the detection of weak earthquake and gravity signals;and(4)the underground roadway support system built with ferromagnetic material interferes the geomagnetic field.We also found that for deep observation in the“ultra-quiet and ultra-clean”environment,the existing geophysical equipment and observation technology have problems of poor adaptability and insufficient precision as well as data cleaning problems,such as the effective separation of the signal and noise of deep observation data.It is also urgent to interpret and comprehensively utilize these high-precision multi-physics observation data. | Yun WANG Yaxin YANG Heping SUN Chengliang XIE Qisheng ZHANG Xiaoming CUI Chang CHEN Yongsheng HE Qiangqiang MIAO Chaomin MU Lianghui GUO Jiwen TENG | 2023 | Science China Earth Sciences2023，66，1： | 3 |
