| 1 | New generation of multi-scale NWP system (GRAPES):general scientific design显示文摘A new generation of numerical prediction system GRAPES (a short form of Global/Regional Assimilation and PrEdiction System) was set up in China Meteorological Administration (CMA). This paper focuses on the scientific design and preliminary results of the numerical prediction model in GRAPES, including basic idea and strategy of the general scientific design, multi-scale dynamic core, physical package configuration, architecture and parallelization of the codes. A series of numerical experiments using the real data with horizontal resolutions from 10 to 280 km and idealized experiments with very high resolution up to 100 m are conducted, giving encouraging results supporting the multi-scale application of GRAPES. The results of operational implementation of GRAPES model in some NWP centers are also presented with stress at evaluations of the capability to predict the main features of precipitation in China. Finally the issues to be dealt with for further development are discussed. | CHEN DeHui XUE JiShan YANG XueSheng ZHANG HongLiang SHEN XueShun HU JiangLin WANG Yu JI LiRen CHEN JiaBin | 2008 | Chinese Science Bulletin2008，53，22： | 70 |
| 2 | LA-(MC)-ICPMS U-Pb zircon geochronology and Lu-Hf isotope compositions of the Taihua complex on the southern margin of the North China Craton显示文摘Widely distributed on the southern margin of the North China Craton,the Taihua complex extends roughly in an east-west direction and the relatively complete successions are found in Lushan County,Henan Province.Like many other Archean terranes,the Taihua Complex can be divided into two major lithological units along the Dangze River,namely gneisses series and supracrustal rocks.The former is located on the north side of the river and chiefly composed of TTG gneisses and amphibolites;the latter on the south side of the river is mainly supracrustal rock.Coupled with the previous studies,the results obtained by this study show that the Taihua complex was formed in a large time span from Neoarchean to Palaeoproterozoic.The TTG gneisses and amphibolites are dated at Neoarchean (2794–2752 Ma).The 2.9 Ga and 3.1 Ga zircons in amphibolites could be xenocrysts.In the North China Craton,the 2.8–2.7 Ga old rocks crop out in several areas e.g.western Shandong Province,Jiaodong Peninsula and Lushan area of Henan Province.In addition,2.8–2.7 Ga detrital zircons or xenocryst zircons have been recognized in Huai’an,Fuping,Wutai areas of North China Craton and also reported in the Early Paleozoic diamondiferous kimberlites in Mengyin and Fuxian.All these age results indicate that the 2.8–2.7 Ga rocks may have been developed much broader region than today’s outcrops.Zircon Hf and whole rock Nd isotopes show that the 2.8–2.7 Ga tectono-thermal event represents an important period of crustal growth with minor ancient crust reworked in the North China Craton.However the formation of supracrustal rocks is limited to 2.2–2.0 Ga in the Palaeoproterozoic time,not the Archaean,as previously believed.Combined with the chronological data of aluminium-rich metamorphic rocks (Khondalite series) on the southern margin of the North China Craton and adjacent areas,it is suggested that the above areas have widely developed Paleoproterozoic passive continental margin environment. | DIWU ChunRong SUN Yong LIN CiLuan WANG HongLiang | 2010 | Chinese Science Bulletin2010，55，23： | 72 |
| 3 | U–Pb ages and Hf isotopes for detrital zircons from quartzite in the Paleoproterozoic Songshan Group on the southwestern margin of the North China Craton显示文摘In situ U-Pb dating and Lu-Hf isotopic analysis were carried out for detrital zircons from quartzite in the Paleoproterozoic Songshan Group on the southern margin of the North China Craton (NCC). The re- sults provide further constraints on the crustal formation and evolution history of NCC. Four 207Pb/206Pb age populations were obtained from 99 analyses, with clusters at ~3.40 Ga, 2.77―2.80 Ga, ~2.50 Ga and 2.34 Ga, respectively. The 3.40 Ga old zircons have similar Hf isotopic compositions to those from Ar- chean rocks in the Jidong and Anshan areas of NCC. However, crustal remnants older than 3.6 Ga have been identified in the southern margin of NCC, the South China Craton, the northwestern part of the Qinling Orogen and its adjacent area. Thus, it is not easy to trace the source rock from which the 3.40 Ga detrital zircons were derived. It can be inferred that the crustal remnants older than 3.40 Ga might have been widely distributed in the North China Craton. The 2.77―2.80 Ga zircons make up a relatively small proportion and have the highest εHf (t) values (up to 6.1±1.6), consistent with the Hf isotopic composition of the depleted mantle at 2.83 Ga. Their single-stage Hf model age of 2.83 Ga is close to their crystallized age, suggesting that their source rocks were extracted from the contemporaneous depleted mantle. The ~2.50 Ga zircon grains constitute about 85% of the total grain population and their Hf isotopic compositions indicate major growth of juvenile crust at ~2.50 Ga but minor reworking of ancient crust. The youngest zircon dated in this study gave an U-Pb age of 2337±23 Ma, which can be considered the maximum depositional age of the formation of the Songshan Group. | DIWU ChunRong SUN Yong YUAN HongLin WANG HongLiang ZHONG XingPing LIU XiaoMing | 2008 | Chinese Science Bulletin2008，53，18： | 54 |
| 4 | Genetic diversity of rice cultivars (Oryza sativa L.) in China and the temporal trends in recent fifty years显示文摘To understand geographical distribution of the genetic diversity of rice cultivars {Oryza sativa L.) and its trends in recent fifty years in China, 453 ’ accessions were analyzed by 36 microsatellites loci and 42 phenotypic traits. Results revealed that the genetic diversity by SSRs is highly consistent with that by phenotypic traits and the genetic diversity of indica cultivars was higher than that of japonica cultivars; the genetic diversity of cultivars declined from 1950s to 1980s and then increased greatly; among the six rice ecological zones (REZs), genetic diversity of REZTl was the highest and those of REZV and REZVT were the lowest at both DNA and phenotypic level. Jiangsu and Jiangxi provinces in the middle and lower reaches of Yangtze River and Sichuan province in southwest of China were the areas with the highest genetic diversity. Breeders in REZV which is an important japonica rice area but with very low genetic diversity should explore more gene resources to widen the genetic backgrounds of cultivars. | QI Yonawen ZHANG Dongling ZHANG Hongliang WANG Meixing SUN Junli WEI Xinghua QIU Zongen TANG Shengxiang CAO Yongsheng WANG Xiangkun LI Zichao | 2006 | Chinese Science Bulletin2006，51，6： | 27 |
| 5 | ~4.1 Ga xenocrystal zircon from Ordovician volcanic rocks in western part of North Qinling Orogenic Belt显示文摘High-precision U-Pb dating by in situ LA-ICP-MS yields an age of 4079±5 Ma for a xenocrystal zircon from Ordovician volcanics of the Caotangou Group in western part of the North Qinling Orogenic Belt. As a result, the North Qinling Orogenic Belt becomes one of a few localities in the world that contain Hadean age records (4276±6 Ma and 4404±8 Ma detrital zircons from Jack Hill of the Yilgarn craton, 4016 Ma Acasta gneisses of the Wopmay Orogeny and Burang quartzite with detrital zircon of 4103 Ma in Tibet). It is also the first report of the Hadean age in Phanerozoic volcanics. The finding of the 4.1 Ga xenocrystal zircon provides not only the geochronological record of the oldest crustal materials in China, but also the condition for further search for rocks forming in the region during the early time of the Earth’s evolution. Thirty-six zircon U-Pb dates from the Ordovician volcanic rocks are subgrouped into seven generations that represent different tectono-magmatic events in the North Qinling Orogenic Belt. Among them, two periods of 0.9-1.5 Ga and 0.4-0.5 Ga are consistent with Mesoproterozoic and Early Paleozoic orogenies, respectively. | WANG HongLiang CHEN Liang SUN Yong LIU XiaoMing xu XueYi CHEN JuanLu ZHANG Hong DIWU ChunRong | 2007 | Chinese Science Bulletin2007，52，21： | 23 |
| 6 | Essential oil and aromatic plants as feed additives in non-ruminant nutrition:a review显示文摘This paper summarizes the current knowledge regarding the possible modes of action and nutritional factors involved in the use of essential oils(EOs) for swine and poultry.EOs have recently attracted increased interest as feed additives to be fed to swine and poultry,possibly replacing the use of antibiotic growth promoters which have been prohibited in the European Union since 2006.In general,EOs enhance the production of digestive secretions and nutrient absorption,reduce pathogenic stress in the gut,exert antioxidant properties and reinforce the animal's immune status,which help to explain the enhanced performance observed in swine and poultry.However,the mechanisms involved in causing this growth promotion are far from being elucidated,since data on the complex gut ecosystem,gut function,in vivo oxidative status and immune system are still lacking.In addition,limited information is available regarding the interaction between EOs and feed ingredients or other feed additives(especially pro- or prebiotics and organic acids).This knowledge may help feed formulators to better utilize EOs when they formulate diets for poultry and swine. | Zhikai Zeng Sai Zhang Hongliang Wang Xiangshu Piao | 2016 | Journal of Animal Science and Biotechnology2016，7，1： | 19 |
| 7 | Agriculture Green Development: a model for China and the world显示文摘Realizing sustainable development has become a global priority.This holds,in particular,for agriculture.Recently,the United Nations launched the Sustainable Development Goals(SDGs),and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development.The overall objective of Agriculture Green Development(AGD)is to coordinate'green'with'development'to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity,high resource use efficiency and low environmental impact.This is a formidable task,requiring joint efforts of government,farmers,industry,educators and researchers.The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system,with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being.This paper addresses the significance,challenges,framework,pathways and potential solutions for realizing AGD in China,and highlights the potential changes that will lead to a more sustainable agriculture in the future.Proposals include interdisciplinary innovations,whole food chain improvement and regional solutions.The implementation of AGD in China will provide important implications for the countries in developmental transition,and contribute to global sustainable development. | Jianbo SHEN Qichao ZHU Xiaoqiang JIAO Hao YING Hongliang WANG Xin WEN Wen XU Tingyu LI Wenfeng CONG Xuejun LIU Yong HOU Zhenling CUI Oene OENEMA William JDAVIES Fusuo ZHANG | 2020 | Frontiers of Agricultural Science and Engineering2020，7，1： | 18 |
| 8 | Changes in soil properties and erodibility of gully heads induced by vegetation restoration on the Loess Plateau, China显示文摘Soil erosion on the Loess Plateau of China is effectively controlled due to the implementation of several ecological restoration projects that improve soil properties and reduce soil erodibility. However, few studies have examined the effects of vegetation restoration on soil properties and erodibility of gully head in the gully regions of the Loess Plateau. The objectives of this study were to quantify the effects of vegetation restoration on soil properties and erodibility in this region. Specifically, a control site in a slope cropland and 9 sites in 3 restored land-use types(5 sites in grassland, 3 in woodland and 1 in shrubland) in the Nanxiaohegou watershed of a typical gully region on the Loess Plateau were selected, and soil and root samples were collected to assess soil properties and root characteristics. Soil erodibility factor was calculated by the Erosion Productivity Impact Calculator method. Our results revealed that vegetation restoration increased soil sand content, soil saturated hydraulic conductivity, organic matter content and mean weight diameter of water-stable aggregate but decreased soil silt and clay contents and soil disintegration rate. A significant difference in soil erodibility was observed among different vegetation restoration patterns or land-use types. Compared with cropland, soil erodibility decreased in the restored lands by 3.99% to 21.43%. The restoration patterns of Cleistogenes caespitosa K. and Artemisia sacrorum L. in the grassland showed the lowest soil erodibility and can be considered as the optimal vegetation restoration pattern for improving soil anti-erodibility of the gully heads. Additionally, the negative linear change in soil erodibility for grassland with restoration time was faster than those of woodland and shrubland. Soil erodibility was significantly correlated with soil particle size distribution, soil disintegration rate, soil saturated hydraulic conductivity, water-stable aggregate stability, organic matter content and root characteristics(including root average diameter, root length density, root surface density and root biomass density), but it showed no association with soil bulk density and soil total porosity. These findings indicate that although vegetation destruction is a short-term process, returning the soil erodibility of cropland to the level of grassland, woodland and shrubland is a long-term process(8–50 years). | GUO Mingming WANG Wenlong KANG Hongliang YANG Bo | 2018 | Journal of Arid Land2018，10，5： | 14 |
| 9 | Formability of AA 2219-O sheet under quasi-static,electromagnetic dynamic,and mechanical dynamic tensile loadings显示文摘The mechanism by which electromagnetic forming(EMF)enhances the formability of metals is unclear owing to the coupling effect of multi-physics fields.In the present work,the associated formability improvement mechanisms were qualitatively categorized and illustrated.This was realized by comparing the formability of fully annealed 2219 aluminum alloy(AA 2219-O)sheet under quasi-static(QS),electromagnetic dynamic(EM),and mechanical dynamic(MD)tensile loadings.It was found that the forming limit of AA 2219-O sheet under EM tensile loading was significantly(45.4%)higher than that under QS tensile loading,and was marginally(3.7%–4.3%)higher than that under MD tensile loading.In addition,the forming limit of AA 2219-O sheet demonstrated a negative dependency on the strain rate within the range of the dynamic tensile tests conducted.The deformation conditions common to EM and MD tensile loadings were responsible for the significant formability improvement compared with QS tensile loading.In particular,the inertial effect was dominant.The different deformation conditions that distinguish EM tensile loading from MD tensile loading resulted in the marginal improvement in formability.This was caused by the absence of a sustaining contact force at the later deformation stage and the lower strain rate.The body force exerted little influence on the formability improvement,and the thermal effect under the two dynamic tensile loadings was negligible. | Hongliang Su Liang Huang Jianjun Li Wang Xiao Hui Zhu Fei Feng Hongwei Li Siliang Yan | 2021 | Journal of Materials Science & Technology2021，，11： | 13 |
| 10 | CRISPR technology is revolutionizing the improvement of tomato and other fruit crops显示文摘Fruits are major sources of essential nutrients and serve as staple foods in some areas of the world.The increasing human population and changes in climate experienced worldwide make it urgent to the production of fruit crops with high yield and enhanced adaptation to the environment,for which conventional breeding is unlikely to meet the demand.Fortunately,clustered regularly interspaced short palindromic repeat(CRISPR)technology paves the way toward a new horizon for fruit crop improvement and consequently revolutionizes plant breeding.In this review,the mechanism and optimization of the CRISPR system and its application to fruit crops,including resistance to biotic and abiotic stresses,fruit quality improvement,and domestication are highlighted.Controversies and future perspectives are discussed as well. | Tian Wang Hongyan Zhang Hongliang Zhu | 2019 | Horticulture Research2019，6，1： | 13 |

| 13 | Influenza A virus H5N1 entry into host cells is through clathrin-dependent endocytosis显示文摘Influenza A virus H5N1 presents a major threat to human health. The entry of influenza virus into host cells is believed to be mediated by hemagglutinin (HA), a virus surface glycoprotein that can bind terminal sialic acid residues on host cell glycoproteins and glycolipids. In this study, we elucidated the pathways through which H5N1 enters human lung carcinoma cell line A549. We first proved that H5N1 can enter A549 cells via endocytosis, as lysosomotropic agents, such as bafilomycin A1 and chloroquine, can rescue H5N1-induced A549 cell death. By using specific inhibitors, and siRNAs that target the clathrin pathway, we further found that H5N1 could enter A549 cells via clathrin-mediated endocytosis, while inhibitors targeting caveolae-mediated endocytosis could not inhibit H5N1 cell entry. These findings expand our understanding of H5N1 pathogenesis and provide new information for anti-viral drug research. | WANG HongLiang & JIANG ChengYu National Key Laboratory of Medical Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100005, China | 2009 | Science China(Life Sciences)2009，52，5： | 11 |
| 14 | Cell multiplication, apoptosis and p-Akt protein expression of bone mesenchymal stem cells of rat under hypoxia environment显示文摘Objective: To elucidate whether cell multiplication, apoptosis, glucose intake and p-Akt protein expression of bone Mesenchy-mal Stem Cells(MSCs) of rats is influenced by a hypoxic environment ex vivo. Methods: Passage 3 of bone marrow MSCs takenfrom Wistar rats, were cultured in a culturing chamber with 94%N2, 1%O2, 5%CO2 at 37℃. At different hypoxia time points, 0, 0.5,1, 4 and 8 h, glucose uptake was assayed by using radiation isotope 3H-G, Apoptotic Rate(AR) and dead rate(DR) were analyzedby flow cytometry(FCM) after Annexin V/PI staining, cell multiplication(by MTT methods) and p-Akt protein by immunocyto-chemistry and western blot. Results: Assay for CD29+, CD44+, CD71+, CD34- , Tn T+(after 5-azacytidine agent inducing) andALP+(after bone differentiation agent inducing) suggested these bone-derived cells were MSCs. The 3H-G intaking ratio(CPM/flask value: 157 ±11, 110 ±11, 107 ±13, 103 ±10, 100 ±9 and 98 ±10) of MSCs at different hypoxia time points, significantlydecreased compared to that of normoxia(P < 0.01) and tended to descend slowly with hypoxia time duration, for which there wasno statistical significance(P > 0.05). The AR(0.09 ±2.03%, 12.9 ±1.72%, 13.7 ±2.26%, 13.8 ±3.01%, 14.1 ±2.78% and 14.7 ±4.01% at 0, 0.5, 1, 4 and 8 h, respectively, P < 0.01) and DR (0.04 ±1.79%, 0.93 ±1.85%, 3.11 ±2.14%, 4.09 ±2.36%, 4.72 ±2.05% and 4.91 ±3.72% at 0, 0.5, 1, 4 and 8 h, respectively, P < 0.05) at different hypoxia time points significantly increasedcompared to those time in normoxia; The AR further went up with time (P < 0.05), however there was no statistical significance(P > 0.05) for the DR. Optical absorption value of MTT methods at different hypoxia time points significantly decreased com-pared to those with a corresponding normoxia time (P < 0.01) and degraded with time (in an hypoxic environment - P < 0.01).IOD of p-Akt protein of MSCs at different hypoxia time points significantly increased (0.367 ±0.031, 0.556 ±0.023, 0.579 ±0.013, 0.660 ±0.024, 0.685 ±0.039 and 0.685 ±0.011, respectively) compared to their equivalents in normoxia (P<0.05), how-ever, there was no statistical significance (P > 0.05) for different hypoxia time points. Hypoxia may result in ultramicrostructurechanges, such as defluvium of Microvilli, apoptotic body, 'margination'and so on and are further aggravated with hypoxia timestretching. Conclusion: Hypoxia may lead to a depression of MSCs intaking glucose, creep of cell multiplication, upregulation ofp-Akt protein and apoptosis of MSCs ex vivo. | Hongliang Kong Ningning Liu Xin Huo Bo Wang Haipeng Zhang Mingyu Gao Guoxian Qi | 2007 | Journal of Nanjing Medical University2007，21，4： | 10 |
| 15 | The influence of pore structure on P-& S-wave velocities in complex carbonate reservoirs with secondary storage space显示文摘Secondary storage spaces with very complex geometries are well developed in Ordovician carbonate reservoirs in the Tarim Basin,which is taken as a study case in this paper.It is still not clear how the secondary storage space shape influences the P-& S-wave velocities (or elastic properties) in complex carbonate reservoirs.In this paper,three classical rock physics models (Wyllie timeaverage equation,Gassmann equation and the Kuster-Toks z model) are comparably analyzed for their construction principles and actual velocity prediction results,aiming at determining the most favourable rock physics model to consider the influence of secondary storage space shape.Then relationships between the P-& S-wave velocities in carbonate reservoirs and geometric shapes of secondary storage spaces are discussed from different aspects based on actual well data by employing the favourable rock physics model.To explain the influence of secondary storage space shape on V P-V S relationship,it is analyzed for the differences of S-wave velocities between derived from common empirical relationships (including Castagna's mud rock line and Greenberg-Castagna V P-V S relationship) and predicted by the rock physics model.We advocate that V P-V S relationship for complex carbonate reservoirs should be built for different storage space types.For the carbonate reservoirs in the Tarim Basin,the V P-V S relationships for fractured,fractured-cavernous,and fractured-hole-vuggy reservoirs are respectively built on the basis of velocity prediction and secondary storage space type determination.Through the discussion above,it is expected that the velocity prediction and the V P-V S relationships for complex carbonate reservoirs should fully consider the influence of secondary storage space shape,thus providing more reasonable constraints for prestack inversion,further building a foundation for realizing carbonate reservoir prediction and fluid prediction. | Wang Haiyang Sam Zandong Sun Yang Haijun Gao Hongliang Xiao Youjun Hu Hongru | 2011 | Petroleum Science2011，8，4： | 10 |
| 16 | A new-generation sand and dust storm forecasting system GRAPES_CUACE/Dust:Model development,verification and numerical simulation显示文摘Based on the new-generation Global/Regional Assimilation and PrEdiction System(GRAPES) developed by the Numerical Prediction Research Center,China Meteorological Administration and the Chinese Unified Atmospheric Chemistry Environment for Dust Atmospheric Chemistry Module(CUACE/Dust) developed by the Centre for Atmosphere Watch and Services(CAWAS) of the Chinese Academy of Meteorological Sciences(CAMS) ,the China sand and dust storm forecasting system GRAPES /CUACE-Dust model has been established.The latest data of land desertification,optical properties of China sand and dust aerosols,daily soil moisture and snow cover over China main land was introduced in this system.The system showed good performance in mass conservation.The comparisons of real-time prediction outputs with surface observations and aerosol indices derived from TOMS ozone spectrophotometers(TOMS AI) indicate that the model can predict the outbreak,development,transport and depletion processes of sand and dust storms accurately over China and the East Asian region.The system makes real-time quantitative prediction of a series of elements including sand and dust injection from the surface,dry and wet deposition amount,dust concentration and optical depth.We selected 7 major dust storms occurring in April 2006 and analyzed the spatiotemporal distribution patterns of dust emission,dry and wet deposition and atmospheric load in this paper.The results showed that about 225 million tons of dust were emitted into the atmosphere from the deserts over east Asia in that month.The 3 major sand and dust sources were just as the following:The deserts in northern Inner Mongolia and the boundary area around China-Mongolia were the first dust sources with a contribution of 153 million tons accounting for 68%of the total emission.The Taklimakan Desert ranked second and contributed approximately 40 million tons accounting for 17%of the dust emission.The Onqin Daga Sandland emitted about 15 million tons or 7%of the total emission.The contributions from other deserts,sandy lands and abandoned farmlands were about only 8%of the total dust emission.The total deposition over the East Asian region in April 2006 was 136 million tons.The regional distribution of dust deposition showed that the 3 major sources were also the major deposition areas.The deposition amount in the 3 major sources accounted for 78%of the total with about 135 million tons falling back to the source regions.The secondary deposition area was the China mainland downriver,where more than 2 million tons deposited accounting for 16%of the total deposition.The deposition over the region east of 120°E including China off-shore regions,Korean Peninsula,Japan and the West Pacific took only 6%of the total deposition,which was about 850000 tons.The analysis on dry and wet deposition showed that dry deposition dominated in the process,accounting for 94%of the total sand and dust depositions in the period and wet deposition only was around for 6%,since it was generally dry with less rainfall over northern China in April. | WANG Hong GONG ShanLing ZHANG HongLiang CHEN Yong SHEN XueShun CHEN DeHui XUE JiShan SHEN YuanFang WU XiangJun JIN ZhiYan | 2010 | Chinese Science Bulletin2010，55，7： | 10 |
| 17 | Pre-stack inversion for caved carbonate reservoir prediction:A case study from Tarim Basin,China显示文摘The major storage space types in the carbonate reservoir in the Ordovician in the TZ45 area are secondary dissolution caves.For the prediction of caved carbonate reservoir,post-stack methods are commonly used in the oilfield at present since pre-stack inversion is always limited by poor seismic data quality and insufficient logging data.In this paper,based on amplitude preserved seismic data processing and rock-physics analysis,pre-stack inversion is employed to predict the caved carbonate reservoir in TZ45 area by seriously controlling the quality of inversion procedures.These procedures mainly include angle-gather conversion,partial stack,wavelet estimation,low-frequency model building and inversion residual analysis.The amplitude-preserved data processing method can achieve high quality data based on the principle that they are very consistent with the synthetics.Besides,the foundation of pre-stack inversion and reservoir prediction criterion can be established by the connection between reservoir property and seismic reflection through rock-physics analysis.Finally,the inversion result is consistent with drilling wells in most cases.It is concluded that integrated with amplitude-preserved processing and rock-physics,pre-stack inversion can be effectively applied in the caved carbonate reservoir prediction. | Zhang Yuanyin Sam Zandong Sun Yang Haijun Wang Haiyang HanJianfa Gao Hongliang Luo Chunshu Jing Bing | 2011 | Petroleum Science2011，8，4： | 9 |

| 19 | Avian influenza H5N1:an update on molecular pathogenesis显示文摘Avian influenza A virus constitutes a large threat to human health. Recent outbreaks of highly pathogenic avian influenza H5N1 virus in poultry and in humans have raised concerns that an influenza pandemic will occur in the near future. Transmission from avian species to humans remains sporadic, but the mortality associated with human infection is very high (about 62%). To date, there are no effective therapeutic drugs or a prophylactic vaccines available, which means that there is still a long way to go before we can eradicate or cure avian influenza. This review focuses on the molecular pathogenesis of avian influenza H5N1 virus infection. An understanding of the viral pathogenesis may facilitate the development of novel treatments or effective eradication of this fatal disease. | WANG HongLiang & JIANG ChengYu National Key Laboratory of Medical Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100005, China | 2009 | Science China(Life Sciences)2009，52，5： | 9 |
| 20 | Targeted delivery of chlorogenic acid by mannosylated liposomes to effectively promote the polarization of TAMs for the treatment of glioblastoma显示文摘Tumor-associated macrophages(TAMs)generally display an immunosuppressive M2 phenotype and promote tumor progression and metastasis,suggesting their potential value as a target in cancer immunotherapy.Chlorogenic acid(CHA)has been identified as a potent immunomodulator that promotes the polarization of TAMs from an M2 to an M1 phenotype.However,rapid clearance in vivo and low tumor accumulation have compromised the immunotherapeutic efficacy of CHA in clinical trials.In this study,mannosylated liposomes are developed for targeted delivery of CHA to TAMs.The immunoregulatory effects of CHA,along with the overall antitumor efficacy of CHA-encapsulated mannosylated liposomes,are investigated through in vitro and in vivo experiments.The prepared CHA-encapsulated mannosylated liposomes exhibit an ideal particle size,favorable stability,and preferential accumulation in tumors via the mannose receptor-mediated TAMs-targeting effects.Further,CHA-encapsulated mannosylated liposomes inhibit G422 glioma tumor growth by efficiently promoting the polarization of the pro-tumorigenic M2 phenotype to the anti-tumorigenic M1 phenotype.Overall,these findings indicate that CHA-encapsulated mannosylated liposomes have great potential to enhance the immunotherapeutic efficacy of CHA by inducing a shift from the M2 to the M1 phenotype. | Jun Ye Yanfang Yang Jing Jin Ming Ji Yue Gao Yu Feng Hongliang Wang Xiaoguang Chen Yuling Liu | 2020 | Bioactive Materials2020，5，3： | 9 |
