| 3 | Re-Os dating of gold-bearing arsenopyrite of the Maoling gold deposit,Liaoning Province,Northeast China and its geological significance显示文摘The Maoling gold deposit, one of the large gold deposits in eastern Liaoning Province, NE China, is an ar- senopyrite-disseminated gold deposit with a resource of ap- proximately 25 t Au and an average Au grade of 3.2 g/t. Six arsenopyrites closely related to Au mineralization of the Maoling gold deposit are dated by Re-Os technique and de- fine a Re-Os isochron with an age of 2316±140 Ma, which suggests that the deposit was formed in the Paleoproterozoic era rather than in the Indosinian period as some early re- searchers suggested. High initial 187Os/188Os ratio of 1.32±0.48 indicates a crustal derivation of the ore-forming material of the deposit, which may be derived from rocks of the Gaixian formation of the Liaohe Group. Furthermore, the result also implies that the age of the Gaixian Formation in the Maoling district is older than 2316±140 Ma. | YU Gang YANG Gang CHEN Jiangfeng QU Wenjun DU Andao HE Wei | 2005 | Chinese Science Bulletin2005，50，14： | 12 |

| 5 | Water regime-nitrogen fertilizer incorporation interaction:Field study on methane and nitrous oxide emissions from a rice agroecosystem in Harbin, China显示文摘Water regime and nitrogen(N) fertilizer are two important factors impacting greenhouse gases(GHG) emission from paddy field, whereas their effects have not been well studied in cold region. In this study, we conducted a two-year field experiment to study the impacts of water regime and N fertilizer on rice yields and GHG emissions in Harbin, China, a cold region located in high latitudes. Our results showed that intermittent irrigation significantly decreased methane(CH_4) emission compared with continuous flooding, however,the decrement was far lower than the global average level. The N_2O emissions were very small when flooded but peaked at the beginning of the disappearance of floodwater. The N fertilizer treatments increased CH_4 emissions at low level(75 kg N/ha). But both CH_4 and N_2O emissions were uninfluenced at the levels of 150 kg N/ha and 225 kg N/ha. Rice yields increased under intermittent irrigation and were highest at the level of 150 kg N/ha. From our results, we recommended that the intermittent irrigation and 150 kg N/ha as the ideal water regime-nitrogen fertilizer incorporation for this area to achieve low GHG emissions without impacting rice yields. | Wenjun Dong Jia Guo Lijun Xu Zhifeng Song Jun Zhang Ao Tang Xijuan Zhang Chunxu Leng Youhong Liu Lianmin Wang Lizhi Wang Yang Yu Zhongliang Yang Yilei Yu Ying Meng Yongcai Lai | 2018 | Journal of Environmental Sciences2018，30，2： | 12 |
| 6 | Two-dimensional metal-organic-framework as a unique theranostic nano-platform for nuclear imaging and chemo-photodynamic cancer therapy显示文摘Nanoscale metal organic frameworks (NMOFs) with porous structure and inherent biodegradability are attractive nanomedicine platforms.In addition to conventional particulate NMOFs,two-dimensional (2D) NMOFs are emerging as a unique type of NMOFs which however have been relatively less explored for nanomedicine applications.Herein,2D NMOFs composed of Zn2+ and tetrakis(4-carboxyphenyl) porphyrin (TCPP) are fabricated and functionalized with polyethylene glycol (PEG).Compared to their particulate counterpart,such 2D NMOFs show greatly increased drug loading capacity and enhanced light-triggered singlet oxygen production,promising for chemotherapy and photodynamic therapy (PDT),respectively.Utilizing the porphyrin structure of TCPP,our 2D NMOFs could be labeled with a diagnostic radioisotope,99mTc,for single photon emission computer tomography (SPECT) imaging,which reveals efficient tumor homing of those 2D NMOFs upon intravenous injection.While offering a remarkable synergistic in vivo antitumor effect for the combined chemo-PDT,such 2D NMOFs show efficient biodegradation and rapid renal clearance.Our work presents the great promise of 2D NMOFs for nanomedicine applications. | Wenjun Zhu Yu Yang Qiutong Jin Yu Chao Longlong Tian Jingjing Liu Ziliang Dong Zhuang Liu | 2019 | Nano Research2019，12，6： | 9 |
| 7 | Tree-ring-based annual precipitation reconstruction in Kalaqin, Inner Mongolia for the last 238 years显示文摘A tree-ring-width chronology of Pinus tabulaeformis from Kalaqin, Inner Mongolia was developed using modern dendroc hronological techniques. Based on the results of correlation function analysis, the total precipitation from the previous August to current July was reconstructed for 1771-2008 AD with an explained variance of 49.3%. The reconstruction correlated well with the dryness/wetness series derived from historical documents, as well as the precipitation reconstruction of the Chifeng-Weichang region. There were eight intervals with greater precipitation than the average (associated with the strong East Asian summer monsoon) and seven intervals lower than the average (weak monsoon). A power spectrum analysis showed that there were 120 a, 80 a, 8 a and 2 a periodicities. | LIU Yu WANG CaiYong HAO WenJun SONG HuiMing CAI QiuFang TIAN Hua SUN Bo Hans W.

| 9 | Overexpression of lysine specific demethylase 1 predicts worse prognosis in primary hepatocellular carcinoma patients显示文摘AIM:To investigate the clinicopathological features and prognostic value of lysine specific demethylase 1(LSD1) in hepatocellular carcinoma(HCC).METHODS:We examined LSD1 expression in 60 paired liver cancer tissues and adjacent noncancerous tissues by quantitative real time polymerase chain reaction(qRT-PCR) and Western blotting.In addition,we analyzed LSD1 expression in 198 HCC samples by immunohistochemistry.The relationship between LSD1 expression,clinicopathological features and patient survival was investigated.RESULTS:Immunohistochemistry,Western blotting,and qRT-PCR consistently confirmed LSD1 overexpression in HCC tissues compared to adjacent non-neoplastic tissues(P < 0.01).Additionally,immunostaining showed more LSD1-positive cells in the higher tumor stage(T3-4) and tumor grade(G3) than in the lower tumor stage(T1-2,P < 0.001) and tumor grade(G1-2,P < 0.001),respectively.Moreover,HCC patients with high LSD1 expression had significantly lower 5-year overall survival rates(P < 0.001) and lower 5-year disease-free survival rates(P < 0.001),respectively.A Cox proportional hazards model further demonstrated that LSD1 over-expression was an independent predictor of poor prognosis for both 5-year disease-free survival [hazards ratio(HR) = 1.426,95%CI:0.672-2.146,P < 0.001] and 5-year overall survival(HR = 2.456,95%CI:1.234-3.932,P < 0.001) in HCC.CONCLUSION:Our data suggest for the first time that the overexpression of LSD1 protein in HCC tissues indicates tumor progression and predicts poor prognosis. | Ze-Kun Zhao Hai-Feng Yu Dao-Rong Wang Ping Dong Lei Chen Wen-Guang Wu WenJun Ding Ying-Bin Liu | 2012 | World Journal of Gastroenterology2012，18，45： | 8 |
| 10 | Mechanical properties and microstructure of an α+β titanium alloy with high strength and fracture toughness显示文摘The Ti-Al-Sn-Zr-Cr-Mo-V-Si (Ti-62A) alloy, an alpha-beta alloy with high strength and fracture toughness, is currently used as an advanced structural material in aerospace and non-aerospace applications. Thermo-mechanical processes can be used to optimize the relationship between its strength and fracture toughness. A Ti-62A alloy bar can be machined through a transus β-forged plus α+β solution treated and aged specimen with a lamellar alpha microstructure. The effects of heat treatment on the mechanical properties were discussed. Heat treatment provided a practical balance of strength, fracture toughness, and fatigue crack growth resistance. A comparison of the Ti-62A alloy with the Ti-62222S alloy under the same thermo-mechanical processing conditions showed that their properties are at the same level. | YU Yang HUI Songxiao YE Wenjun XIONG Baiqing | 2009 | Rare Metals2009，28，4： | 8 |
| 11 | Whole genome sequencing of 10K patients with acute ischaemic stroke or transient ischaemic attack: design, methods and baseline patient characteristics显示文摘Background and purpose Stroke is the second leading cause of death worldwide and the leading cause of mortality and long-term disability in China,but its underlying risk genes and pathways are far from being comprehensively understood.We here describe the design and methods of whole genome sequencing(WGS)for 10914 patients with acute ischaemic stroke or transient ischaemic attack from the Third China National Stroke Registry(CNSR-III).Methods Baseline clinical characteristics of the included patients in this study were reported.DNA was extracted from white blood cells of participants.Libraries are constructed using qualified DNA,and WGS is conducted on BGISEQ-500 platform.The average depth is intended to be greater than 30×for each subject.Afterwards,Sentieon software is applied to process the sequencing data under the Genome Analysis Toolkit best practice guidance to call genotypes of single nucleotide variants(SNVs)and insertion-deletions.For each included subject,21 fingerprint SNVs are genotyped by MassARRAY assays to verify that DNA sample and sequencing data originate from the same individual.The copy number variations and structural variations are also called for each patient.All of the genetic variants are annotated and predicted by bioinformatics software or by reviewing public databases.Results The average age of the included 10914 patients was 62.2±11.3 years,and 31.4%patients were women.Most of the baseline clinical characteristics of the 10914 and the excluded patients were balanced.Conclusions The WGS data together with abundant clinical and imaging data of CNSR-III could provide opportunity to elucidate the molecular mechanisms and discover novel therapeutic targets for stroke. | Si Cheng Zhe Xu Yang Liu Jinxi Lin Yong Jiang Yilong Wang Xia Meng Anxin Wang Xinying Huang Zhimin Wang Guohua Chen Songdi Wu Zhengchang Jia Yongming Chen Xuerong Qiu Jun Wu Binbin Song Weizhong Ji Zhongping An Wenjun Xue Lili Zhao Yu Geng Hongyan Li Hao Li Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 8 |
| 12 | Structural Surface Crack Monitoring Method Based on Electrical Potential Technique and Modern Surface Technology显示文摘Crack monitoring plays a great role in modern structural health monitoring, however, most of the conventional crack inspections have disadvantages in terms of the accuracy, expense, reliability, durability and level of instrumentation required. Thus, development of a simple and reliable crack inspection technique that allows continuous monitoring has been desired. In this paper, electrical potential technique and modern surface technology are employed together to develop a new structural surface crack monitoring method. A special crack monitoring coating sensor based on electrical potential technique was deposited on the hot spot of the structure by modern surface technology. The sensor consists of three layers: the isolated layer, the sensing layer and the protective layer. The isolated layer is prepared by anodic oxidation technology, the sensing layer is made of ion plated copper, and the protective layer is made of silicone. The thickness of each layer is at micrometer magnitude. The electrical conductivity of the sensor is very stable, and the fatigue performance of the specimen with or without coating sensor is nearly unchanged. The crack monitoring experiment result shows that there are two sudden rises of the coating sensor electrical potential values, corresponding to different stages of the crack initiation and propagation. Since the width of the surface coating sensor is only 0.5 mm, this crack monitoring sensor can detect the propagation of cracks less than 0.5 mm long. The method proposed takes the simplicity of electrical potential technique and can monitor surface crack of nearly all kinds of structures precisely. The results of this paper may form the basis of a new crack monitoring system. | CUI Ronghong HE Yuting YU Zhiming LI Hongpeng SHU Wenjun DU Jinqiang | 2011 | Chinese Journal of Mechanical Engineering2011，24，4： | 7 |
| 13 | Estimation of the Type of Low Energy Discharge in GIS Adopting Characteristic Gas显示文摘In order to guarantee safe operations, low energy discharge within gas insulated switchgear (GIS) should be detected as soon as possible before they develop severely and cause final breakdown failures. This paper aims to present a GIS discharge diagnosis technique adopting gaseous decompositions. To reach this aim, needle-plate electrode and the sphere-plate electrode with metallic particles on the plate are designed to simulate two kinds of low energy discharge, namely, corona discharge and spark discharge, respectively. After sampling and analyzing the gases, different yields of gaseous by-products under different types of low energy discharge are obtained. Based on the decomposition mechanisms reported by previous researches and the experiment results, it can be concluded that S2OF10, SO2F2 , and SO2 can be used as the characteristic gas to identify low energy discharge; the increment of S2OF10 can indicate the occurrence of low energy discharges while the volume ratio between SO2F2 and SO2 can define the type of low energy discharge. | CHEN Jun LI Li YAO Weijian TANG Yang ZHENG Xiaoguang YU Jianhui LUO Yunbai ZHOU Wenjun | 2011 | Wuhan University Journal of Natural Sciences2011，16，4： | 7 |
| 14 | Dosage effect of multiple genes accounts for multisystem disorder of myotonic dystrophy type 1显示文摘Multisystem manifestations in myotonic dystrophy type 1(DM1)may be due to dosage reduction in multiple genes induced by aberrant expansion of CTG repeats in DMPK,including DMPK,its neighboring genes(SIX5 or DMWD)and downstream MBNLh However,direct evidence is lacking.Here,we develop a new strategy to generate mice carrying multigene heterozygous mutations to mimic dosage reduction in one step by injection of haploid embryonic stem cells with mutant Dmpk,Six5 and Mbnll into oocytes.The triple heterozygous mutant mice exhibit adult-onset DM1 phenotypes.With the additional mutation in Dmwd,the quadruple heterozygous mutant mice recapitulate many major manifestations in congenital DM1.Moreover,muscle stem cells in both models display reduced sternness,providing a unique model for screening small molecules for treatment of DM1.Our results suggest that the complex symptoms of DM1 result from the reduced dosage of multiple genes. | Qi Yin Hongye Wang Na Li Yifu Ding Zhenfei Xie Lifang Jin Yan Li Qiong Wang Xinyi Liu Liuqing Xu Qing Li Yongjian Ma Yanbo Cheng Kai Wang Cuiqing Zhong Qian Yu Wei Tang Wanjin Chen Wenjun Yang Fan Zhang Chen Ding Lan Bao Bin Zhou Ping Hu Jinsong Li | 2020 | Cell Research2020，30，2： | 7 |
| 15 | Dynamic fracture toughness of TA15ELI alloy studied by instrumented impact test显示文摘The dynamic fracture toughness of TA15ELI alloy with two types of microstructures was studied by instrumented impact test.Charpy specimens with both the 0.2 mm U-notch and the a/W = 0.2 pre-crack were adopted to compare notch sensitivity in the two microstructures.The result shows that the specimen with Widmanst?tten microstructure exhibits a better dynamic fracture toughness and lower notch sensitivity than that with lath-like microstructure.Fracture surfaces in the case of the two microstructures are analyzed to have a ductile and brittle mixed feature under dynamic loading.The fracture surface of lath-like microstructure is composed of dimples and tear ridges,while that of Widmanst?tten microstructure is covered with rough block-like facets and dimples and tear ridges.The α phase boundaries and α/β interfaces act as locations for void nucleation and crack arrest and deviation.The decrease in width of α phase lamellae leads to the increase in the amount of boundaries and interfaces,which causes the increase in the consumption of impact energy and results in the improvement in dynamic fracture toughness. | LIU Rui,HUI Songxiao,YE Wenjun,XIONG Baiqing,YU Yang,and FU Yanyan State Key Laboratory for Fabrication & Processing of Nonferrous Metals,General Research Institute for Nonferrous Metals,Beijing 100088,China | 2010 | Rare Metals2010，29，6： | 6 |

| 17 | Chemoselective hydrogenolysis of tetrahydrofurfuryl alcohol to 1,5-pentanediol over Ir-MoO_x/SiO_2 catalyst显示文摘In this work, MoOx promoted Ir/SiO2 catalysts were prepared and used for the selective hydrogenolysis of tetrahydrofurfuryl alcohol(THFA)to 1,5-pentanediol in a continuous flow reactor. The effects of different noble metals(Ir, Pt, Pd, Ru, Rh), supports and Ir contents were screened.Among the investigated catalysts, 4 wt%Ir-MoOx/SiO2 with a Mo/Ir atomic ratio of 0.13 exhibited the best catalytic performance. The synergy between Ir particles and the partially reduced isolated MoOx species attached on them is essential for the excellent catalytic performance of Ir-MoOx/SiO2. The catalyst exhibited a better hydrogenolysis efficiency of THFA with the selectivity of 1,5-pentanediol of 65%–74% at a conversion of THFA of 70%–75% when the initial THFA concentration is ranging from 20 wt% and 40 wt%. And higher system pressure was also in favor of the conversion of THFA. During a stability test, the conversion of THFA and 1,5-pentanediol yield over Ir-MoOx/SiO2 decreased with reaction time, which can be explained by the leaching of Mo species during the reaction. | Zhiqiang Wang Boonrat Pholjaroen Mengxia Li Wenjun Dong Ning Li Aiqin Wang Xiaodong Wang Yu Cong Tao Zhang | 2014 | Journal of Energy Chemistry2014，23，4： | 6 |
| 18 | Soft measurement of wood defects based on LDA feature fusion and compressed sensor images显示文摘We proposed a detection method for wood defects based on linear discriminant analysis(LDA) and the use of compressed sensor images. Wood surface images were captured, using a camera Oscar F810C IRF camera,and then the image segmentation was performed, and the defect features were extracted from wood board images. To reduce the processing time, LDA algorithm was used to integrate these features and reduce their dimensions. Features after fusion were used to construct a data dictionary and a compressed sensor was designed to recognize the wood defects types. Of the three major defect types, 50 images live knots, dead knots, and cracks were used to test the effects of this method. The average time for feature fusion and classification was 0.446 ms with the classification accuracy of 94%. | Chao Li Yizhuo Zhang Wenjun Tu Cao Jun Hao Liang Huiling Yu | 2017 | Journal of Forestry Research2017，28，6： | 6 |
| 19 | Tensile and fracture properties of Ti-62A alloy plate with different microstructures显示文摘Ti-62A alloy plates with three different types of microstructure, fully equiaxed, bimodal, and Widmanst tten, were obtained by various heat treatments to investigate the effects of microstructure on the tensile and fracture properties at room temperature. The results reveal that Widmanst tten microstructure exhibits good damage tolerance behavior considering strength, fracture toughness, and fatigue crack growth behavior, while the bimodal microstructure shows good comprehensive properties considering the plasticity synthetically. Optical microscopy (OM) and scanning electron microscopy (SEM) microstructure analyses on fracture and fatigue crack path demonstrate that the dependence of mechanical properties and fatigue crack growth behavior on microstructural feature are attributed to the α lamellae width and the α colony size. | LIU Rui HUI Songxiao YE Wenjun YU Yang FU Yanyan SONG Xiaoyun DENG Xiguang | 2012 | Rare Metals2012，31，5： | 5 |
| 20 | Hydrogen production via steam reforming of bio-oil model compounds over supported nickel catalysts显示文摘The steam reforming of four bio-oil model compounds(acetic acid,ethanol,acetone and phenol) was investigated over Ni-based catalysts supported on Al2O3 modified by Mg,Ce or Co in this paper.The activation process can improve the catalytic activity with the change of high-valence Ni(Ni2O3,NiO) to low-valence Ni(Ni,NiO).Among these catalysts after activation,the Ce-Ni/Co catalyst showed the best catalytic activity for the steam reforming of all the four model compounds.After long-term experiment at 700°C and the S/C ratio of 9,the Ce-Ni/Co catalyst still maintained excellent stability for the steam reforming of the simulated bio-oil(mixed by the four compounds with the equal masses).With CaO calcinated from calcium acetate as CO2 sorbent,the catalytic steam reforming experiment combined with continuous in situ CO2 adsorption was performed.With the comparison of the case without the adding of CO2 sorbent,the hydrogen concentration was dramatically improved from 74.8% to 92.3%,with the CO2 concentration obviously decreased from 19.90% to 1.88%. | Huaqing Xie Qingbo Yu Xin Yao Wenjun Duan Zongliang Zuo Qin Qin | 2015 | Journal of Energy Chemistry2015，24，3： | 5 |
