| 2 | New incompatible pair of TCM:Epimedii Folium combined with Psoraleae Fructus induces idiosyncratic hepatotoxicity under immunological stress conditions显示文摘Epimedii Folium(EF)combined with Psoraleae Fructus(PF)is a common modern preparation,but liver injury caused by Chinese patent medicine preparations containing EF and PF has been frequently reported in recent years.Zhuangguguanjiewan pills(ZGW),which contain EF and PF,could induce immune idiosyncratic liver injury according to clinical case reports and a nonhepatotoxic dose of lipopolysaccharide(LPS)model.This present study evaluated the liver injury induced by EF or PF alone or in combination and investigated the related mechanism by using the LPS model.Liver function indexes and pathological results showed that either EF or PF alone or in combination led to liver injury in normal rats;however,EF or PF alone could lead to liver injury in LPS-treated rats.Moreover,EF combined with PF could induce a greater degree of injury than that caused by EF or PF alone in LPS-treated rats.Furthermore,EF or PF alone or in combination enhanced the LPS-stimulated inflammatory cytokine production,implying that IL-1β,which is processed and released by activating the NLRP3 inflammasome,is a specific indicator of EF-induced immune idiosyncratic hepatotoxicity.Thus,EF may induce liver injury through enhancing the LPS-mediated proinflammatory cytokine production and activating the NLRP3 inflammasome.In addition,the metabolomics analysis results showed that PF affected more metabolites in glycerophospholipid and sphingolipid metabolic pathways compared with EF in LPS model,suggesting that PF increased the responsiveness of the liver to LPS or other inflammatory mediators via modulation of multiple metabolic pathways.Therefore,EF and PF combination indicates traditional Chinese medicine incompatibility,considering that it induces idiosyncratic hepatotoxicity under immunological stress conditions. | Yuan Gao Zhilei Wang Jinfa Tang Xiaoyi Liu Wei Shi Nan Qin Xiaoyan Wang Yu Pang Ruisheng Li Yaming Zhang Jiabo Wang Ming Niu Zhaofang Bai Xiaohe Xiao | 2020 | Frontiers of Medicine2020，14，1： | 32 |
| 3 | Characterizations and mechanical properties of impregnated diamond segment using Cu-Fe-Co metal matrix显示文摘Diamond impregnated Cu-Fe-Co based saw-blade segments are directly processed by vacuum and pressure-assisted sintering at different temperature,with the purpose of reducing the cobalt content in diamond tools.Copper and iron are used as the bonding elements and co-balt-chrome pre-alloyed powder is used as the hardening phase.Effects of sintering temperature on microstructures and mechanical properties of the sintered matrix and diamond graphitization were investigated by X-ray diffraction analysis,electron probe micro-analyzer,universal testing machine,digital Rockwell hardness tester and Raman scattering analyzer.Results showed that microstructures of the sintered matrix were refined and porosities in the sintered matrix were closed to a more spherical-like shape with the increase of the sintering temperature.Densification,hardness and tensile strength of the matrix sintered at 820 ℃ were 12.75%,2.72% and 156.38% higher than that of the matrix sintered at 740 ℃,respectively.Diamond graphitization was not occurred at 820 ℃.The hardness and the tensile strength rose 32.8% and 13.5%,respectively,after 7.5 h ageing treatment.The matrix densification ascent and the dispersed distribution of Co-Cr pre-alloyed powders contributed a hardness improvement and a tensile strength improvement to the Cu-Fe based matrix. | Li, Wensheng Zhang, Jie Wang, Shucai Dong, Hongfeng Li, Yaming Liu, Yi | 2012 | Rare Metals2012，31，1： | 19 |
| 4 | Cementation and diagenetic fluid of algal dolomites in the Sinian Dengying Formation in southeastern Sichuan Basin显示文摘The Sinian Dengying Formation in China hosts one of the oldest gas-bearing reservoirs in the world.With a long geological history,it has developed into the reservoir rocks,whose quality depends on chemical dissolution and cementation.Despite presence of cavities and pores in the algal dolomites of the Dengying Formation,they were mostly filled with various forms of dolomite cements.Therefore,the investigation of these dolomites and their evolution is significant for analyzing the mechanism of pore space preservation.There are five types of cements in the Dengying Formation,which were well sampled for lab measurements such as thin section,cathodeluminescence,minor elements,isotope analysis of carbon,oxygen and strontium,in attempt to explore the fillers' geochemical characteristics and the diagenetic fluids.They are characterized as follows:firstly,fibrous rim dolomite cement is a typical product formed at sea bottom,and geochemically very similar to the matrix(micrite and microcrystalline dolomite),which could be a reflection of the geochemical characteristics of water at that time;secondly,the diagenetic fluids of the foliated dolomite cements tend to be inheriting,derived from the shallow burial 'imprisoned' seawater;thirdly,fine-to medium-grained dolomite cements with fairly high strontium isotopes and low carbon and oxygen isotopes were precipitated chiefly in freshwater during the period of uplifting caused by Tongwan tectonic movement;fourthly,coarse-grained dolomite cements bear a relatively high percentage of Mn element,but low in Fe and Sr,with carbon and oxygen isotopes remarkably shifted to negative values,which all show that they are related to hydrocarbon maturation and migration,and corresponding Thermochemical Sulfate Reduction;lastly,saddle-shaped dolomite cements are hydrothermally associated,and they were formed in high-temperature brine,which had passed through the areas rich in radioactive strontium isotopes. | SHI ZeJin WANG Yong TIAN YaMing WANG ChangCheng | 2013 | Science China Earth Sciences2013，56，2： | 16 |

| 6 | Effects of five-element music therapy on elderly people with seasonal affective disorder in a Chinese nursing home显示文摘OBJECTIVE: To explore the effects of five-element music therapy on elderly patients with seasonal affective disorder in a Chinese nursing home.METHODS: The patients(n=50) were recruited from a Shijingshan district nursing home in Beijing,China. They were randomly assigned to two groups, a treatment group and a control group,with 25 participants in each group. The patients received music therapy for 1-2 h each week over an8-week period. The music therapy involved four phases: introduction, activities, listening to the Chinese five-element music, and a concluding phase.The participants in the control group did not listen to the five-element music. This study consisted of two parts:(a) a qualitative study that used focus groups to understand the feelings of the patients with seasonal affective disorder;(b) a quantitative study that involved administration of the self-rating depression scale(SDS) and Hamilton depression scale(HAMD) before and after treatment.RESULTS:(a) Qualitative analysis results: strength derived from the five-element group music therapy and emotional adjustment. The five-element group music therapy can reduce patients' psychological distress and let them feel inner peace and enhance their life satisfaction.(b) No significant difference in SDS and HAMD scores was found between the two groups(P>0.05) prior to treatment. After treatment,the mean SDS score of the control group was 49.9±18.8, while the treatment group's score was 40.2±18.1. The HAMD score of the control group was11.2±3.1, and the treatment group's score was 8.8±4.9. Following 8 weeks of music therapy, the SDS and HAMD scores of the treatment group were significantly lower than those for the control group(P<0.05).CONCLUSION: Five-element music therapy alleviated the symptoms of seasonal affective disorder in the elderly patients. | Xifang Liu Xin Niu Qianjin Feng Yaming Liu | 2014 | Journal of Traditional Chinese Medicine2014，34，2： | 8 |
| 7 | Effect of particle inertia on temperature statistics in particle-laden homogeneous isotropic turbulence显示文摘The fluid temperature statistics along particle trajectories is crucial to under- stand the mechanisms of turbulent non-isothermal or reactive fluid-particle flow, especially for the Lagrangian model of non-isothermal particle-laden turbulent flow. In the present study, direct numerical simulations were utilized to generate temperature field statistics in particle-laden incompressible stationary homogeneous isotropic turbulent flows, which is focused on the effect of particle response time on the Lagrangian statistics of the particle and the fluid temperature seen by particles. It shows that, for the particles with τp/τk < 1, the ratio of the fluid intensity seen by particle to fluid temperature intensities deceased as τp/τk increased; while for larger particles (τp/τk > 1), the trend is inversed. For small parti- cles (τp/τk<5), the Lagrangian autocorrelation coefficient of the particle temperature RpT decreases as the particle inertia (τp/τk) increases. The trend is reversed for larger particles. The autocorrelation of fluid temperature along the particle path, RpfT, decreased as the particle inertia increased. And as the particle inertia increased, the autocorrelation coeffi- cient of the fluid temperature seen by particle decreased more rapidly than that of the particle temperature. The mean temperature gradient contributes to the correlation be- tween the particles velocity component and temperature fluctuations in the direction of the gradient. For the particles with τp/τk<1, the magnitude of the correlation coefficient in- creases as the particle inertia increases, while this value is independent of the particle time constant for larger particles. | HE Zhu LIU Zhaohui CHEN Sheng LIU Yaming ZHENG Chuguang | 2006 | Science China(Technological Sciences)2006，49，2： | 8 |
| 8 | Fate of mercury in flue gas desulfurization gypsum determined by Temperature Programmed Decomposition and Sequential Chemical Extraction显示文摘A considerable amount of Hg is retained in flue gas desulfurization(FGD) gypsum from Wet Flue Gas Desulfurization(WFGD) systems. For this reason, it is important to determine the species of Hg in FGD gypsum not only to understand the mechanism of Hg removal by WFGD systems but also to determine the final fate of Hg when FGD gypsum is disposed. In this study, Temperature Programmed Decomposition(TPD) and Sequential Chemical Extraction(SCE) were applied to FGD gypsum to identify the Hg species in it. The FGD gypsum samples were collected from seven coal-fired power plants in China, with Hg concentrations ranging from 0.19 to 3.27 μg/g. A series of pure Hg compounds were used as reference materials in TPD experiments and the results revealed that the decomposition temperatures of different Hg compounds increase in the order of Hg_2Cl_2< HgCl_2< black HgS < Hg_2SO_4< red HgS < HgO < HgSO_4. The Hg compounds existing in FGD gypsums identified by TPD included HgCl_2, Hg_2Cl_2, Hg_2SO_4, black HgS and red HgS, of which mercury sulfides were the primary compounds. The results of SCE indicated that Hg was mainly distributed in the strongly complexed phase. The low Hg content in FGD gypsum increases the ambiguity of assigning extraction fractions to certain Hg species by SCE. The fact that the primary compounds in FGD gypsum are HgS phases leads the leaching of Hg in the natural environment to be quite low, but a considerable amount of Hg may be released during the industrial heating process. | Zhenwu Zhu Yuqun Zhuo Yaming Fan Zhipeng Wang | 2016 | Journal of Environmental Sciences2016，28，5： | 8 |
| 9 | Uplift and evolution of Helan Mountain显示文摘The Helan Mountain lies in the northwest margin of Ordos Basin and its uplift periods have close relations with the tectonic feature and evolution of the basin. There are many views on the uplift time of Helan Mountain, which is Late Triassic and Late Jurassic. It is concluded by the present strata, magmatic rock and hot fluid distribution that the Helan Mountain does not uplift in Late Triassic to Middle Jurassic but after Middle Jurassic. Through the research of the sedimentary strata and deposit rate in Yinchuan Graben which is near to the Helan Mountain, it is proved that the Helan Mountain uplifts in Eocene with a huge scale and in Pliocene with a rapid speed. The fission track analysis of apatite and zircon can be used to determine the precise uplift time of Helan Mountain, which shows that four stages of uplifting or cooling: Late Jurassic to the early stage of Early Cretaceous, mid-late stage of Early Cretaceous, Late Cretaceous and since Eocene. During the later two stages the uplift is most apparent and the mid-late stage of Early Cretaceous is a regional cooling course. Together with several analysis ways, it is considered that the earliest time of Helan Mountain uplift is Late Jurassic with a limited scale and that Late Cretaceous uplift is corresponding to the whole uplift of Ordos Basin, extensive uplift happened in Eocene and rapid uplift in Pliocene. | ZHAO HongGe LIU ChiYang WANG Feng WANG JianQiang LI Qiong YAO YaMing | 2007 | Science China Earth Sciences2007，50，z2： | 7 |
| 10 | A Simulator for Producing of High Flux Atomic Oxygen Beam by Using ECR Plasma Source显示文摘In order to study the atomic oxygen corrosion of spacecraft materials in low earth orbit environment, an atomic oxygen simulator was established. In the simulator, a 2.45 GHz microwave source with maximum power of 600 W was launched into the circular cavity to generate ECR (electron cyclotron resonance) plasma. The oxygen ion beam moved onto a negatively biased Mo plate under the condition of symmetry magnetic mirror field confine, then was neutralized and reflected to form oxygen atom beam. The properties of plasma density, electron temperature, plasma space potential and ion incident energy were characterized. The atomic oxygen beam flux was calibrated by measuring the mass loss rate of Kapton during the atomic 5~30 eV and a cross section of φ80 mm could be obtained under the operating pressure of 10-1~10-3 Pa. Such a high flux source can provide accelerated simulation tests of materials and coatings for space applications. | Shuwang DUO, Meishuan LI and Yaming ZHANGShenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China | 2004 | Journal of Materials Science & Technology2004，20，6： | 7 |
| 11 | Highly Stretchable and Transparent Ionic Conductor with Novel Hydrophobicity and Extreme-Temperature Tolerance显示文摘Highly stretchable and transparent ionic conducting materials have enabled new concepts of electronic devices denoted as iontronics,with a distinguishable working mechanism and performances from the conventional electronics.However,the existing ionic conducting materials can hardly bear the humidity and temperature change of our daily life,which has greatly hindered the development and real-world application of iontronics.Herein,we design an ion gel possessing unique traits of hydrophobicity,humidity insensitivity,wide working temperature range(exceeding 100℃,and the range covered our daily life temperature),high conductivity(10^(-3)~10^(-5) S/cm),extensive stretchability,and high transparency,which is among the bestperforming ionic conductors ever developed for flexible iontronics.Several ion gel-based iontronics have been demonstrated,including large-deformation sensors,electroluminescent devices,and ionic cables,which can serve for a long time under harsh conditions.The designed material opens new potential for the real-world application progress of iontronics. | Lei Shi Kun Jia Yiyang Gao Hua Yang Yaming Ma Shiyao Lu Guoxin Gao Huaitian Bu Tongqing Lu Shujiang Ding | 2020 | Research2020，，1： | 7 |

This article provides a brief overview of the function of the most prominent flaviviruses-induced or-hijacked cytoskeletal structures including actin, microtubules and intermediate filaments, mainly focus on infection by dengue virus, Zika virus and West Nile virus. We suggest that virus interaction with host cytoskeleton to be an interesting area of future research. | Yue Zhang Wei Gao Jian Li Weihua Wu Yaming Jiu | 2019 | Virologica Sinica2019，34，1： | 6 |
| 14 | New insights into hepatitis B virus biology and implications for novel antiviral strategies显示文摘Hepatitis B virus(HBV), a small DNA virus with a unique replication mode, can cause chronic hepatitis(CHB), which is characterized by the persistence of the viral covalently closed circular DNA that serves as the template for HBV replication and the production of large amounts of secreted HBV surface antigen(HBs Ag) that is present in excess of the levels of infectious virus. Despite the success of currently approved antiviral treatments for CHB patients, including interferon and nucleotide analogs, which suppress HBV replication and reduce the risk of CHB-related liver diseases, these therapies fail to eradicate the virus in most of the patients. With the development of the cell and animal models for HBV study, a beter understanding of the HBV life cycle has been achieved and a series of novel antiviral strategies that target diferent stages of HBV replication have been designed to overcome the viral factors that contribute to HBV persistence. Such basic HBV research advancements and therapeutic developments are the subject of this review. | Jieliang Chen Min Wu Kuancheng Liu Wen Zhang Yaming Li Xiaohui Zhou Lu Bai Zhenghong Yuan | 2015 | National Science Review2015，2，3： | 6 |
| 15 | The effect of applied voltages on the structure,apatite-inducing ability and antibacterial ability of micro arc oxidation coating formed on titanium surface显示文摘The micro arc oxidation(MAO)coatings with different concentrations of Ca,P and Zn elements are successfully formed on the titanium substrate at the different applied voltages.After MAO treatment,the MAO coating exhibits the porous surface structure and composed of anatase and rutile TiO2 phases.Meanwhile,the average size and density of micro-pores on the MAO coatings have been modified via the adjusting the applied voltages.In addition,the contents of the incorporated elements such as Zn,Ca and P elements in the MAO coatings have been optimized.The bonding strength test results reveal that the MAO coating shows higher bonding strength,which is up to 45±5 MPa.Compared to the pure Ti plate,the MAO coating formed at 350 and 400 V show good apatite-inducing ability.Meanwhile,the MAO coating containing Zn,Ca and P elements have better antibacterial ability for E.coli and S.aureus.Thus,the incorporation of Zn,Ca and P elements was an effective method to improve the antibacterial ability.Moreover,the concentrations of Zn,Ca and P elements could be adjusted with the changing of the applied voltages.As a result,the enhancement of the antibacterial ability on the MAO coating surfaces was depended on the comprehensive effect of the incorporated elements and the surface property of MAO coatings. | Qing Du Daqing Wei Yaming Wang Su Cheng Shang Liu Yu Zhou Dechang Jia | 2018 | Bioactive Materials2018，3，4： | 6 |
| 16 | Experimental investigation of ash deposits on convection heating surfaces of a circulating fluidized bed municipal solid waste incinerator显示文摘Incineration of municipal solid waste(MSW) is a waste treatment method which can be sustainable in terms of waste volume reduction, as well as a source of renewable energy.During MSW combustion, increased formation of deposits on convection heating exchanger surfaces can pose severe operational problems, such as fouling, slagging and corrosion.These problems can cause lower heat transfer efficiency from the hot flue gas to the working fluid inside the tubes. A study was performed where experiments were carried out to examine the ash deposition characteristics in a full-scale MSW circulating fluidized bed(CFB) incinerator, using a newly designed deposit probe that was fitted with six thermocouples and four removable half rings. The influence of probe exposure time and probe surface temperature(500, 560, and 700℃) on ash deposit formation rate was investigated. The results indicate that the deposition mass and collection efficiency achieve a minimum at the probe surface temperature of 560℃. Ash particles are deposited on both the windward and leeward sides of the probe by impacting and thermophoretic/condensation behavior. The major inorganic elements present in the ash deposits are Ca,Al and Si. Compared to ash deposits formed on the leeward side of the probe,windward-side ash deposits contain relatively higher Ca and S concentrations, but lower levels of Al and Si. Among all cases at different surface temperatures, the differences in elemental composition of the ash deposits from the leeward side are insignificant.However, as the surface temperature increases, the concentrations of Al, Si, K and Na in the windward-side ash deposits increase, but the Ca concentration is reduced. Finally,governing mechanisms are proposed on the basis of the experimental data, such as deposit morphology, elemental composition and thermodynamic calculations. | Zhi Tang Xiaoping Chen Daoyin Liu Yaming Zhuang Minghua Ye Hongchan Sheng Shaojuan Xu | 2016 | Journal of Environmental Sciences2016，28，10： | 6 |
| 17 | Temporal-spatial distribution and ore-forming material source of gold,copper and silver polymetallic ore deposits in the Fuping mantle structure zone显示文摘This study was conducted following research on metallogenesis in the Zhangjiajie-Xuanhua and East Hebei mantle branch structure zones. The Fuping mantle branch structure zone is one where Au, Cu and Ag poly-metallic ore resources are concentrated in North Hebei. However, there has existed a long-standing controversy on the temporal-spatial distribution of ore resources and their ore-forming material sources. In terms of age dating and the comprehensive analysis of S, Pb, O, C and Si isotopes, it is considered that the temporal-spatial distribution of ore resources in this mantle branch structure zone is obviously controlled by the Fuping mantle branch structure. In space there is developed such a metallogenic pattern as to be Ag, Pb and Zn polymetallic ore deposits with gold appearing inside and copper appearing outside. Metallogenesis is dated mainly at Yanshanian, the ore-forming materials were derived predominantly from the deep interior of the Earth, and ore-forming fluids were derived largely from Yanshanian magmatism. | WANG Baode NIU Shuyin SUN Aiqun LIU Yaming XIE Yan JIANG Xiaoping ZHAO Yongli GAO Yincang ZHAO Fuwang | 2010 | Chinese Journal Of Geochemistry2010，29，3： | 6 |
| 18 | Gas chromatography-mass spectrometry analysis on compounds in volatile oils extracted from Yuan Zhi(Radix Polygalae) and Shi Chang Pu(Acorus Tatarinowii) by supercritical CO_2显示文摘OBJECTIVE:To analyze the constituents of volatile oils extracted from Yuan Zhi(Radix Polygalae),Shi Chang Pu(Acorus Tatarinowii),and a mixture of the two herbs.METHODS:The volatile oils were extracted using supercritical fluid extraction(SFE) with CO 2,and the constituents of the volatile oil extracts were analyzed by gas chromatography-mass spectrometry(GC-MS).The relative content of each component was calculated using peak area normalization.RESULTS:The optimized SFE conditions were 45 MPa at 35℃ for 2 h.Twenty-four compounds were identified in the extract from the Yuan Zhi(Radix Polygalae) and Shi Chang Pu(Acorus Tatarinowii) mixture,and six of these had relative contents >1.These compounds were 1,2-dimethoxy-4-(2-propenyl)-benzene;1,2,3-trimethoxy-5-(2-propenyl)-benzene;β-asarone;(Z,Z) 9,12-octadecadienoic acid;(Z) 6-octadecenoic acid;and ethyl oleate.Combination of the herbs increased the number of pharmacologically active substances in the extract and decreased the number of compounds with one benzene ring compared with the extracts from the individual herbs.CONCLUSION:These results indicate there is a synergistic relationship among the compounds in these herbs. | Yingli Wang Liping Chang Xiaoguang Zhao Xianbin Meng Yaming Liu | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 4 |
| 19 | Global characteristics of the second-order ionospheric delay error using inversion of electron density profiles from COSMIC occultation data显示文摘It is a well known fact that ionospheric delay error is a predominant factor which influences the positioning accuarcy of GNSS.Although the main part of the first-order ionospheric delay error can be removed by the frequency-dependent behaviors of the ionosphere,the second-order ionospheric delay error must be eliminated to achieve millimetre-scale positioning accuracy.Due to COSMIC occultation providing electron density profiles on the global scale,the paper presents the first-order and the second-order ionospheric delay error analysis on the global scale using the inversion of electron density profiles from COSMIC occultation data during 2009–2011.Firstly,because of the special geographical location of three ISR(incoherent scatter radar),the first-order and the second-order ionospheric delay errors are calculated and discussed;the paper also shows and analyzes the diurnal,seasonal,semi-annual variation of ionospheric delay error with respect to signal direction.Results show that for the L1 signal path,the first-order ionospheric delay error is the largest near the equator,which is circa 7 m;the maximum second-order ionospheric delay error are circa 0.6 cm,0.8 cm and 0.6 cm respectively for L1 signals coming from the zenith,the north and the south at 10 degree elevation angles.The second-order ionospheric delay error on the L1 signal path from zenith are the symmetry between 15°and 15°with respect to magnetic equator,and are nearly zero at the magnetic equator.For the first time,the second-order ionospheric delay error on the global scale is presented,so this research will greatly contribute to analysing the higher-order ionospheric delay error characteristics on the global scale. | WANG Hu WANG Cheng WANG JieXian DANG YaMing BAI GuiXia WANG QianXin | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，2： | 4 |
| 20 | The alignment of AlN platelets in polymer matrix and its anisotropic thermal properties显示文摘The thermal conductivity of polymer composites can be enhanced by the vertical alignment of anisotropic aluminum nitride(AlN)platelet fillers in polymer matrices.The AlN platelets in polymer matrix were aligned in the direction of in-plane and out-of-plane by using the doctor blading and the lamination process.The alignment of AlN plates in the out-of-plane or the in-plane direction has been confirmed by XRD and FE-SEM investigations.The polymer composite with the out-of-plane aligned AlN platelets showed almost 1.5 times or 2 times higher thermal conductivity than those with the AlN spheres or the in-plane aligned AlN platelets at the same filler content,respectively.This result could be attributed to the improvement of thermal pathway generated along the plane of platelets and the decrease of interfaces between the filler and the polymer. | Chang-Yeoul Kim Thi My Linh Dang Yaming Zhang Jian-Feng Yang Bo Wang | 2019 | Journal of Materiomics2019，5，4： | 4 |
