| 1 | Cluster analysis for syndromes of real-world coronary heartdisease with angina pectoris显示文摘Syndromes of coronary heart disease with angina pectoris were analyzed to provide guidance forclinical practice and to improve accuracy of traditional Chinese medicine (TCM) diagnoses and efficacy of TCMtreatment. A total of 860 cases with coronary heart disease with angina pectoris were selected from TCM ClinicalResearch Information Sharing System for TCM clinics and research. Syndromes were automatically extractedwith the cluster method and were analyzed to provide objective evidence for clinical studies. Final syndromeclassifications were recognized and confirmed by clinical experts. Popular syndromes included Qi and blooddeficiency, blood stasis and obstruction collaterals, liver depression and spleen deficiency, and Qi stagnation andblood stasis. Syndromes Qi and blood deficiency and blood stasis and obstruction collaterals accounted for 28.61%of total syndromes, whereas liver depression and spleen deficiency and Qi stagnation and blood stasis accountedfor 26.44%. The main syndrome elements comprised Qi deficiency, blood deficiency, blood stasis, and Qistagnation. | Yufeng Zhao Xueyun Yu Xinyu Cao Lin Luo Liyun He Shusong Mao Li Ma Peijing Rong Yuxue Zhao Guozheng Li Baoyan Liu | 2018 | Frontiers of Medicine2018，12，5： | 28 |
| 2 | Analysis of Five Differentially Expressed Gene Families in Fast Elongating Cotton Fiber显示文摘Using the suppression subtractive hybridization method, we isolated five gene families,including proline-rich proteins (PRPs), arabinogalactan proteins (AGPs), expansins, tubulins and lipid transfer proteins (LTPs), from fast elongating cotton fiber cells. Expression profile analysis using cDNA array technology showed that most of these gene families were highly expressed during early cotton fiber developmental stages (0-20 days post anthesis, DPA). Many transcripts accumulated over 50 fold in 10 DPA fiber cells than in 0 DPA samples. The entire gene family-AGP, together with 20 individual members in other 4 gene families, are reported in cotton for the first time. Accumulation of cell wall proteins, wall loosening enzymes, microtubules and lipid transfer proteins may contribute directly to the elongation and development of fiber cells. | Jian-XunFENG Sheng-JianJI Yong-HuiSHI YuXU GangWEI Yu-XianZHU | 2004 | Acta Biochimica et Biophysica Sinica2004，36，1： | 27 |
| 3 | Bone marrow mesenchymal stem cell therapy in ischemic stroke: mechanisms of action and treatment optimization strategies显示文摘Animal and clinical studies have confirmed the therapeutic effect of bone marrow mesenchymal stem cells on cerebral ischemia, but their mechanisms of action remain poorly understood. Here, we summarize the transplantation approaches, directional migration, differentiation, replacement, neural circuit reconstruction,angiogenesis, neurotrophic factor secretion, apoptosis, immunomodulation, multiple mechanisms of action,and optimization strategies for bone marrow mesenchymal stem cells in the treatment of ischemic stroke.We also explore the safety of bone marrow mesenchymal stem cell transplantation and conclude that bone marrow mesenchymal stem cell transplantation is an important direction for future treatment of cerebral ischemia. Determining the optimal timing and dose for the transplantation are important directions for future research. | Guihong Li Fengbo Yu Ting Lei Haijun Gao Peiwen Li Yuxue Sun Haiyan Huang Qingchun Mu | 2016 | Neural Regeneration Research2016，11，6： | 22 |
| 4 | Characteristics of Cd isotopic compositions and their genetic significance in the lead-zinc deposits of SW China显示文摘Up to now,the evaporation and condensation,as well as the biological absorption and inorganic absorptions,have been proved to be major factors in Cd isotope fractionation.And Cd isotopes have been widely applied in studies on the universal evolution and marine environment and so on.However,only a few researches have been conducted in applying Cd isotopes to trace the source of metallogenic material and the evolution of the ore-forming fluid in a complex mineralization environment,especially in a hydrothermal ore-formation system.We measured the Cd isotopic compositions of sphalerite,galena,and ores from five lead-zinc deposits in SW China,and found that the 114/110Cd values varied from 1.53‰to 0.34‰,with a total range of1.87‰,which is greater than most of measured geological samples.Meanwhile,through contrasting the Cd content with Cd isotopic compositions of different deposits,it may be concluded that different genetic lead-zinc deposits have different Cd content and isotopic compositions,which could be a tool for the studies on the origin of ore deposits.Also,the biomineralization and crystal fractionation may also result in Cd isotope fractionation.In a word,although the research of Cd isotopes is presently at the preliminary stage(especially in hydrothermal ore-formation system),this study demonstrated that Cd isotopes can give a clue in tracing the evolution of ore-forming fluid and metallogenic environment. | ZHU ChuanWei WEN HanJie ZHANG YuXu FAN HaiFeng FU ShaoHong XU Juan QIN TingRong | 2013 | Science China Earth Sciences2013，56，12： | 14 |
| 5 | Earthquake-related Tectonic Deformation of Soft-sediments and Its Constraints on Basin Tectonic Evolution显示文摘The authors introduced two kinds of newly found soft-sediment deformation-syn-sedimentary extension structure and syn-sedimentary compression structure,and discuss their origins and constraints on basin tectonic evolution.One representative of the syn-sedimentary extension structure is syn-sedimentary boudinage structure,while the typical example of the syn-sedimentary compression structure is compression sand pillows or compression wrinkles.The former shows NW-SE-trending contemporaneous extension events related to earthquakes in the rift basin near a famous Fe-Nb-REE deposit in northern China during the Early Paleozoic(or Mesoproterozoic as proposed by some researches),while the latter indicates NE-SW-trending contemporaneous compression activities related to earthquakes in the Middle Triassic in the Nanpanjiang remnant basin covering south Guizhou,northwestern Guangxi and eastern Yunnan in southwestern China.The syn-sedimentary boudinage structure was found in an earthquake slump block in the lower part of the Early Paleozoic Sailinhudong Group,20 km to the southeast of Bayan Obo,Inner Mongolia,north of China.The slump block is composed of two kinds of very thin layers—pale-gray micrite(microcrystalline limestone)of 1?2 cm thick interbedded with gray muddy micrite layers with the similar thickness.Almost every thin muddy micrite layer was cut into imbricate blocks or boudins by abundant tiny contemporaneous faults,while the interbedded micrite remain in continuity.Boudins form as a response to layer-parallel extension(and/or layer-perpendicular flattening)of stiff layers enveloped top and bottom by mechanically soft layers.In this case,the imbricate blocks cut by the tiny contemporaneous faults are the result of abrupt horizontal extension of the crust in the SE-NW direction accompanied with earthquakes.Thus,the rock block is,in fact,a kind of seismites.The syn-sedimentary boudins indicate that there was at least a strong earthquake belt on the southeast side of the basin during the early stage of the Sailinhudong Group.This may be a good constraint on the tectonic evolution of the Bayan Obo area during the Early Paleozoic time.The syn-sedimentary compression structure was found in the Middle Triassic flysch in the Nanpanjiang Basin.The typical structures are compression sand pillows and compression wrinkles.Both of them were found on the bottoms of sand units and the top surface of the underlying mud units.In other words,the structures were found only in the interfaces between the graded sand layer and the underlying mud layer of the flysch.A deformation experiment with dough was conducted,showing that the tectonic deformation must have been instantaneous one accompanied by earthquakes.The compression sand pillows or wrinkles showed uniform directions along the bottoms of the sand layer in the flysch,revealing contemporaneous horizontal compression during the time between deposition and diagenesis of the related beds.The Nanpanjiang Basin was affected,in general,with SSW-NNE compression during the Middle Triassic,according to the syn-sedimentary compression structure.The two kinds of syn-sedimentary tectonic deformation also indicate that the related basins belong to a rift basin and a remnant basin,respectively,in the model of Wilson Cycle. | LU Hongbo ZHANG Yuxu ZHANG Qiling XIAO Jiafei | 2006 | Acta Geologica Sinica(English Edition)2006，80，5： | 13 |
| 6 | NUMERICAL ANALYSIS ON THREE-DIMENSIONAL FLOW FIELD OF TURBINE IN TORQUE CONVERTER显示文摘Three-dimensional flow field of turbine in torque converter is simulated by numerical calculation in order to improve the performance of torque converter. Calculation model of a torque converter is presented based on the mixing-plane technology. In the calculation of flow field,the 3D N-S equations are separated by finite-volume method and solved by semi-implicit method for pressure-linked equations(SIMPLE). Based on flow field calculation,the flow field of turbine is simulated. The velocity and pressure in the flow field of turbine are analyzed. The external performance of the torque converter is also calculated. Results of flow simulation show that there are secondary flow,off flow and velocity gradient in turbine passage. The validity of numerical simulation is verified by comparing the results of numerical simulation with experiment data. | LIU Yue PAN Yuxue LIU Chunbao | 2007 | Chinese Journal of Mechanical Engineering2007，20，2： | 11 |
| 7 | Inhibitory Activity of Honeysuckle Extracts against Influenza A Virus In Vitro and In Vivo显示文摘Honeysuckle has been used in the treatment of influenza virus infection for thousands of years in China.However,its main active components and the functional mechanisms remain to be elucidated.Here,four honeysuckle extracts,including acids extract,flavonoids extract,total extract and acids-flavonoids mixture,were prepared to clarify the main active antiviral components.The cytopathic effect reduction assay showed that all the four extracts inhibited the replication of influenza viruses H1N1,H3N2 and the oseltamivir-resistant mutant strain H1N1-H275Y.The acids-flavonoids mixture had the strongest inhibitory effects in vitro with EC_(50) values of 3.8,4.1,and >20 lg/m L against H1N1,H3N2 and H1N1-H275Y,respectively,showing competitive antiviral activity with oseltamivir and ribavirin.Honeysuckle acids extract also showed the most significant antiviral activity in vivo.Oral administration of the acids extract at a dosage of 600 mg/kg/d effectively alleviated viral pneumonia,maintained body weight and improved the survival rate to 30% of the mice infected with a lethal dose of H1N1.The results of time-of-drug addition experiment and neuraminidase (NA) inhibition assay showed that honeysuckle extracts had a broad-spectrum inhibitory effect against influenza virus NAs.The flavonoid extract showed the strongest inhibitory effect on the NA of influenza virus H7N9 with an IC_(50) of 24.7 lg/m L.These results suggested that these extracts might exert their antiviral activity by suppressing the release of influenza viruses.Briefly,our findings demonstrate that acids and flavonoids extracts of honeysuckle are the major antiviral active components,and the acids extract has the potential to be developed into an antiviral agent against influenza virus,especially for oseltamivirresistant viruses. | Mengwei Li Yuxu Wang Jing Jin Jie Dou Qinglong Guo Xue Ke Changlin Zhou Min Guo | 2021 | Virologica Sinica2021，36，3： | 11 |
| 8 | Effects of melatonin on the expression of iNOS and COX-2 in rat models of colitis显示文摘AIM: To investigate the effects of melatonin (MT) on the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in rat models of colitis.
METHODS: Healthy adult Sprague-Dawlay (SD) rats of both sexes, weighing 280±30 g, were employed in the present study. The rat models of colitis were induced by either acetic acid or 2,4,6-trinitrobenzene sulfonic acid (TNBS) enemas. The experimental animals were randomly divided into melatonin treatment and model control group that were intracolicly treated daily with melatonin at doses of 2.5, 5.0, 10.0 mg.kg-1 and equal amount of saline respectively from 24 h following induction of colitis in rats inflicted with acetic acid enema and the seventh day in rats with TNBS to the end of study. A normal control group of rats treated with neither acetic acid nor TNBS but saline enema was also included in the study. On the 28th day of the experiment, the rat colon mucosal damage index (CDMI) was calculated, and the colonic prostaglandin E2(PGE2), nitric oxide (NO), as well as the iNOS and COX-2expression were also determined biochemically or immunohistochemically.
RESULTS: CDMI increased to 2.87±0.64 and 3.12±1.12respectively in rats treated with acetic acid and TNBS enema,which was in accordance with the significantly elevated colonic NO and PGE2 contents, as well as the up-regulated colonic iNOS and COX-2 expression in both of the two rat models of colitis. With treatment by melatonin at the doses of 5.0 and 10.0 mg@kg-1, CDMI in both models of rat colitis was significantly decreased (P<0.05-0.01), which accorded synchronously and unanimously with the reduced colonic NO and PGE2 content, as well as the down-regulated expression of colonic iNOS and COX-2.
CONCLUSION: Melatonin has a protective effect on colonic injury induced by both acetic acid and TNBS enemas, which is probably via a mechanism of local inhibition of iNOS and COX-2 expression in colonic mucosa. | Wei-GuoDong QiaoMei Jie-PingYu Jian-MingXu LiXiang YuXu | 2003 | World Journal of Gastroenterology2003，9，6： | 7 |
| 9 | Mo isotopes in the Lower Cambrian formation of southern China and its implications on paleo-ocean environment显示文摘Over the past decade, as one of nontraditional stable isotopes, Mo isotope has developed rapidly and now become an important geochemical proxy to trace paleo-oceanic and atmospheric evolution through geological history. In this paper, Early Cambrian formations in southern China are investigated. The results indicate that δ 97/95Mo values of Early Cambrian seawater may have been larger than 1.4‰, values that are close to those of the modern ocean. It was also found that the variations in Mo isotope composition in samples from two sections (Huangjiawan and Gezhongwu in Guizhou) were closely related to changes in redox conditions during sedimentary processes. Combining our results with existing data, a preliminary model for the evolution of seawater Mo isotope composition through geological history was provided. It indicated that Mo isotopic variations were generally consistent with the evolution of atmospheric oxygen. | WEN HanJie ZHANG YuXu FAN HaiFeng HU RuiZhong | 2009 | Chinese Science Bulletin2009，54，24： | 6 |
| 10 | Effects of temperature and pressure on the structural and optical properties of ZnO films grown by pulsed laser deposition显示文摘ZnO thin films were deposited on fused silica via pulsed laser deposition (PLD) at substrate temperatures from 300°C to 800°C and ambient oxygen pressures ranging from 10-2 mTorr to 240 mTorr. X-ray diffraction (XRD) and Raman spectra indicated that wurtzite ZnO was obtained in all cases. The highly c-oriented ZnO films were obtained for oxygen pressures above 11 mTorr. The room-temperature photoluminescence (PL) spectra demonstrated that all the films exhibited strong near-band-edge (NBE) emission, while deep-level (DL) emission was also observed in films deposited at oxygen pressures below 80 mTorr. From analysis of the XRD, Raman and photoluminescence PL data, an optimal condition was identified for the deposition of highly crystallized ZnO films. | ZHAO Lei, XU ChangShan, LIU YuXue & LIU YiChun Center for Advanced Opto-Electronic Functional Materials Research, Northeast Normal University, Changchun 130024, China | 2010 | Science China(Technological Sciences)2010，53，2： | 6 |
| 11 | An Intra-Oceanic Subduction System Influenced by Ridge Subduction in the Diyanmiao Subduction Accretionary Complex of the Xar Moron Area,Eastern Margin of the Central Asian Orogenic Belt显示文摘This study focuses on the geology,geochemistry,Sr-Nd isotopes and their tectonic settings of three types of basalts in Diyanmiao ophiolite in the Xar Moron area located on the eastern margin of the Central Asian Orogenic Belt.Type I basalts are oceanic tholeiites with a depleted light rare earth element(LREE)pattern,which are similar to the typical N-mid-oceanic ridge basalt(MORB)and suggests that they were formed at a mid-oceanic ridge.The initial 87Sr/86Sr ratios of Type I basalts range from 0.703966 to 0.705276 and theεNd(t)values are from 16.49 to 17.15,indicating that they were derived from a depleted mantle source.Type II basalts belong to the medium-potassium calc-akaline series and have the geochem-ical characteristics of Nb-enriched basalt(NEB)with high Nb content(14.5 ppm)and strong enrichment in LREEs,implying that they were created by the partial melting of mantle wedge peridotite that previously metasomatized by slab melts.Type III basalts are high-Al basalt(HAB)with high-Al contents(Al_(2)0_(3)=16.75 wt.%-18.00 wt.%),distinct Nb depletion and high Th/Yb ratios.Thus they were likely gen-erated in a normal island-arc setting.Therefore,the association of MORB,NEB,and HAB in the study area may be due to the subduction of a mid-oceanic ridge,and the Diyanmiao ophiolite is proposed to be formed in the forearc setting of a mid-oceanic ridge subduction system. | Yang Cheng Qinghui Xiao Tingdong Li Liquan Xu Yuxu Fan Yan Li Lingjun Guo Jinli Pang Weiming Yuan | 2021 | Journal of Earth Science2021，32，1： | 6 |
| 12 | Effect of manual acupuncture on bowel motility in normal kunming mouse显示文摘OBJECTIVE:To observe the effects of acupuncture on motility of jejunum and distal colon at different acupoints on normal Kunming mice.METHODS:The jejunal and colorectal motor activity of forty Kunming mice were recorded by the intra-intestinal capsule.The capsules contained with distilled water were placed into the cavities of jejunum and distal colon.The changes of bowel were compared with the background activity recorded before any stimulation.The chosen acupoints were as follows:Zusanli(ST 36) on the lower legs,Tianshu(ST 25) on the mid-lower abdomen.RESULTS:Manual acupuncture(MA) at Zusanli(ST36) significantly promoted the motility of jejunum and distal colon(manifested as increased change rate of average amplitude and increased change rate of mean area under the contractile curve) of normal Kunming mice(P < 0.01).MA atTianshu(ST25) significantly inhibited the motility of jejunum(manifested as decreased change rate of average amplitude,decreased change rate of mean area under the contractile curve,and the reduced frequency) of normal Kunming mice(P < 0.01),while significantly increased the distal colonic motility(manifested as increased amplitude and increased mean area under the contractile curve) of normal Kunming mice(P < 0.01).CONCLUSION:MA at specific acupoints[Zusanli(ST 36),Tianshu(ST 25)]has different effects on the motility of jejunum and distal colon,which might involve the segmental innervations of the related nerve. | Zhao Yuxue Cui Changxiang Qin Qingguang Ben Hui Gao Junhong Yu Xiaochun Zhu Bing | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 5 |
| 13 | Effects of three needling manipulations of the right-side Zusanli(ST 36) on brain using functional magnetic resonance imaging显示文摘OBJECTIVE: To investigate the effects on the brain using three needling manipulations(twirling, lifting-thrusting, and twirling plus lifting-thrusting)when the right-side Zusanli(ST 36) acupoint was stimulated with needles.METHODS: Seventeen healthy subjects accepted three needling manipulations stimulating the right Zusanli(ST 36) over separate days. Functional magnetic resonance imaging was used to detect changes in the brain during the manipulations, and then the needling sensations were recorded using the MGH acupuncture sensation scale(MASS) after each scan. f MRI data were processed using Statistical Parametric Mapping 8 to analyze the positiveand negative activation in the brain induced by different acupuncture manipulations.RESULTS: The individual needling sensations showed no statistically significant differences among the three manipulations. However, the MASS index showed that lifting-thrusting > twirling plus lifting-thrusting > twirling. Lifting-thrusting activated left premotor cortex, left postcentral,right middle frontal gyrus, left inferior frontal gyrus,right lingual gyrus, left insula, right putamen, bilateral cingulate gyrus and right cerebellum; and deactivated bilateral hippocampus and left caudate.Twirling activated bilateral orbital middle frontal gyrus, left opercular and triangular inferior frontal gyrus, and right middle occipital gyrus; and deactivated bilateral precuneus, right amygdala, left anterior cingulate gyrus, right inferior temporal gyrus,right middle frontal gyrus, right supplementary motor gyrus, and left postcentral. Twirling plus lifting-thrusting activated bilateral postcentral, left inferior occipital gyrus, left insula, left thalamus, left cingulate gyrus, and right putamen; and deactivated right superior frontal gyrus, right superior parietal gyrus, right temporal gyrus, right middle occipital gyrus, right insula, and left lingual gyrus. Pairwise comparisons of the three manipulations showed that signals induced by lifting-thrusting were the strongest, especially in the limbic system,followed by twirling plus lifting-thrusting; twirling alone was the weakest.CONCLUSION: Three methods of needling manipulations similarly activated areas associated with the somatosensory system, vision, cognition, and emotional regulation. This may have significant implications for acupuncture in clinical practice. | Lu Fengyan Gao Junhong Wang Yuanyuan Dai Qiufu Bao Yan Hong Yang Zhang Guolei Xin Juanjuan Zhao Yuxue Wu Shuyang Chen Yuanyuan Li Xiaojiao Fang Jiliang Yu Xiaochun | 2017 | Journal of Traditional Chinese Medicine2017，37，3： | 5 |
| 14 | Mesoporous silica rods with cone shaped pores modulate inflammation and deliver BMP-2 for bone regeneration显示文摘Biomaterials with suitable osteoimmunomodulation properties and ability to deliver osteoinductive biomolecules,such as bone morphogenetic proteins,are desired for bone regeneration.Herein,we report the development of mesoporous silica rods with large cone-shaped pores(MSR-CP)to load and deliver large protein drugs.It is noted that those cone-shaped pores on the surface modulated the immune response and reduced the pro-inflammatory reaction of stimulated macrophage.Furthermore,bone morphogenetic proteins 2(BMP-2)loaded MSR-CP facilitated osteogenic differentiation and promoted osteogenesis of bone marrow stromal cells.In vivo tests confirmed BMP-2 loaded MSR-CP improved the bone regeneration performance.This study provides a potential strategy for the design of drug delivery systems for bone regeneration. | Chun Xu Lan Xiao Yuxue Cao Yan He Chang Lei Yin Xiao Wujin Sun Samad Ahadian Xueting Zhou Ali Khademhosseini Qingsong Ye | 2020 | Nano Research2020，13，9： | 5 |
| 15 | Composite Stratigraphy of the Sailinhudong Group and Ore-bearing Micrite Mounds in the Bayan Obo Deposits,Inner Mongolia,China显示文摘Based on studies of sequence stratigraphy, event stratigraphy, biostratigraphy and lithostratigraphy, it is concluded that the Sailinhudong Group is a part of the Bayan Obo Group. Some trilobite fragments are first found in thin sections of the rock from the lower part of the Sailinhudong Group and some Ordovician acritarchs and chitinozoans are also found in this group. A formationa unit of carbonate seismites is first recognized in the upper part and a huge micrite mound is first identified at the top. Dolomite, the host rock of the super giant Bayan Obo Fe-Nb-REE deposits, is neither an igneous carbonatite nor a common bedded sedimentary carbonate, but a huge micrite mound. It has the same macroscopic characters as the micrite mounds at the top of the Sailinhudong Group, which suggests that they should be of the same horizon. According to the fossils, the Sailinhudong and Bayan Obo Groups should be of the Early Palaeozoic rather than the Middle Proterozoic.

| 16 | Molybdenum isotopic composition as a tracer for low-medium temperature hydrothermal ore-forming systems:A case study on the Dajiangping pyrite deposit,western Guangdong Province,China显示文摘Little is known about the range or controls on the molybdenum isotopic composition of low-medium temperature hydrothermal ore-forming systems.We present molybdenum isotope data from 12 hydrothermal syndepositional silicalite and carbonaceous slate samples from the Dajiangping pyrite deposit in western Guangdong Province,South China.The δ 97/95Mo values from Orebody III range from ?0.02‰ to 0.29‰,with an average of 0.18‰.In contrast,the composition values from Orebody IV display a larger variation from ?0.70‰ to 0.62‰.However,the five samples from the main ore bed all show strong negative values.This indicates that the significant variation in molybdenum isotopic composition supports different hydrothermal ore-forming metallogenesis and a metallogenic environment between the two orebodies.Orebody III is likely to have been deposited from submarine exhalative hydrothermal fluids under a relatively strong reducing environment and Orebody IV may have also been influenced by hydrothermal superimposition in a more oxidized disequilibrium condition.In addition,the δ 97/95Mo values of Orebody IV are clearly negative,together with the values increasing stratigraphically upward in the ore beds,suggesting that the metallogenic environment of Orebody IV is different from the open oceanic systems.There might be dynamic fractionation in this restricted environment.Therefore,the molybdenum isotope can be used as an effective tracer for the ore-forming fluid and metallogenic environment. | SONG ShiMing HU Kai WEN HanJie ZHANG YuXu LI Kuang FAN HaiFeng | 2011 | Chinese Science Bulletin2011，56，21： | 4 |
| 17 | Isotopic Geochemistry of Cadmium:A Review显示文摘Cadmium(Cd) is a scarce, but not an extremely rare element in the Earth's crust(crustal average: 0.2 ppm Cd). Geochemically, Cd exhibits thiophile, lithophile, and volatile behavior in different geologic processes. Biologically, it is a nutrient-like element that is closely related to P and Zn and is toxic element to organisms. Presently, Cd isotopes have been successfully utilized to trace Cd sources and nutrient cycling in marine systems in addition to unearthing other geochemical processes. Using published studies and our recent work, this survey summarizes the chemical preparation and mass spectrometry of Cd isotopes. It also reviews Cd isotopic compositions and fractionation mechanisms in nature as well as experiments. | ZHU Chuanwei WEN Hanjie ZHANG Yuxu LIU Yizhang WEI Rongfei | 2015 | Acta Geologica Sinica(English Edition)2015，89，6： | 3 |
| 18 | Pollution characteristics and health risk assessment of polycyclic aromatic hydrocarbons and nitrated polycyclic aromatic hydrocarbons during heating season in Beijing显示文摘Polycyclic aromatic hydrocarbons(PAHs)and their nitrated derivatives(NPAHs)attract continuous attention due to their outstanding carcinogenicity and mutagenicity.In order to investigate the diurnal variations,sources,formation mechanism,and health risk assessment of them in heating season,particulate matter(PM)were collected in Beijing urban area from December 26,2017 to January 17,2018.PAHs and NPAHs in PM were quantitatively analyzed via gas chromatography-mass spectrometry(GC-MS).Average daily concentrations of PAHs and NPAHs were(78±54)ng/m^(3)and(783±684)pg/m^(3),respectively.The concentrations of them were significantly higher at nighttime than at daytime,and NPAHs concentrations were 1-2 orders of magnitude lower than PAHs concentrations.In the heating season,the dominant species of PAHs include benzo[b]fluoranthene,fluoranthene,pyrene,and chrysene,while 9-nitroanthracene,2+3-nitrofluoranthene,and 2-nitropyrene were dominant species for NPAHs.NPAHs were found to have a single peak during heating and to be primarily distributed in the 0.4-0.7μm particle size.Primary emissions such as biomass burning,coal combustion,and traffic emissions were the major sources of PAHs.NPAHs were produced by the primary source of vehicle emissions and the secondary reaction triggered by OH radicals,as well as biomass burning during daytime.According to the health risk assessment,the total carcinogenic risk was higher in adults than in children.While upon oral ingestion,the carcinogenic risk in children was higher than that of adults,but the risk of adults was higher than children through skin contact and respiratory inhalation. | Xurong Bai Jie Wei Yanqin Ren Rui Gao Fahe Chai Hong Li Fei Xu Yuxue Kong | 2023 | Journal of Environmental Sciences2023，，1： | 3 |
| 19 | Agent-based effectiveness evaluation method and impact analysis of airborne laser weapon system in cooperation combat显示文摘The laser weapons will play a special role in the future high-tech war.To study the impact of airborne laser weapon on the System-of-System(SoS)effectiveness in cooperative com-bat,this paper proposes an indicator construction method based on the combination of the weapon capability indicator system and the combat simulation.The indicator system of capability is divided into 4 layers by the bottom-to-up generation mechanism of indicators.It can describe the logical relationship between the indicator layers from a qualitative perspective.Together with the 4 layers capability indicator system,a hierarchical framework of airborne laser weapon is established by the agent-based modeling and simulation.Impact analyses show that the SoS effectiveness improves with the increase of the laser weapon output power,the laser launcher diameter,and the photoelectric sensor pixel.But the SoS effectiveness promotion brought by the photoelectric sensor pixel is limited.The results can be used for the development of tactical airborne laser weapon. | Likuan SHI Yang PEI Qijia YUN Yuxue GE | 2023 | Chinese Journal of Aeronautics2023，36，4： | 3 |
