| 1 | Adakite-type sodium-rich rocks in Awulale Mountain of west Tianshan:Significance for the vertical growth of continental crust显示文摘The sodium-rich dacites and albite porphyries of Permian in the Awulale Mountain of west Tianshan have unique chemical and trace element signatures identical to adakite. These intermediate-acidic igneous rocks are characterized by high Na2O, Al2O3 and Sr contents and high Sr/Y and La/Y ratios (>40 and >20, respectively), and low Y and Yb contents, and strong depletion in HREE, and positive Eu anomaly. The (143Nd/144Nd)i is in the range from0.51236 to 0.51248 and the εNd(t) is positive value (+0.79-+3.11); the (87Sr/86Sr)i is in the range from 0.7052 to 0.7054. These Nd and Sr isotopic composition features indicate that the source rocks of these adakite-type rocks are from a weakly depleted mantle, or a depleted mantle, but was contaminated by the crustal materials. These adakite-type rocks were most likely derived from the partial melting of new underplated basaltic rocks under the conditions of amphibo-lite to eclogite transition in the postcollisional environment of North Xinjiang during the Permian | XIONG Xiaolin ZHAO Zhenhua BAI Zhenghua MEI Houjun WANG Yixian WANG Qiang XU Jifeng Niu Hecai BAO Zhiwei | 2001 | Chinese Science Bulletin2001,46,10: | 25 |
| 2 | Geochronology and geochemistry of the Fangcheng Neoproterozoic alkali-syenites in East Qinling orogen and its geodynamic implications显示文摘Finding of Neoproterozoic syenites at Fangcheng in the northern Qinling region of the East Qinling orogen provides an important constraint on timing of tectonic transformation to extensional regime. The alkaline pluton consists mainly of nepheline syenite,aegirine syenite,and alkali-feldspar syenite. The syenites are of intermediate (SiO2=54%―62%),rich in alkali (K2O+Na2O=12%―15%),aluminum (Al2O3=16.81%―23.26%) and large ion lithophile elements (LILE),without any obvious Nb,Ta,Zr,and Hf anoma-lies. The Fangcheng syenites are geochemically characterized by relative enrichment of LREE,minor differentiation of HREE,significant negative Eu anomalies (Eu=0.13―0.23),less negative εNd(t) values of -1.37 to -3.90,young Nd model ages of 1364 to 1569 Ma,and high zircon saturation temperatures of 915 to 1044℃. The syenitic magmas probably originated from small proportion melting of upper mantle in an extensional regime of intraplate-anorogenic tectonic setting,and have been slightly contaminated by crustal materials during ascending and/or emplacement. LA-ICP-MS zircon U-Pb dating yields ages of 844.3±1.6 Ma (MSWD=0.86),suggesting that the Fangcheng alkaline syenites formed in the early Neo-proterozoic. They are the oldest Neoproterozoic alkaline rocks ever recognized in the Qinling orogen as well as in South China. This implies that the tectonic regime of the Qinling region would have transformed from post-collisional stretch to intraplate-anorogenic extension no later than 844 Ma. | BAO ZhiWei WANG Qiang BAI GuoDian ZHAO ZhenHua SONG YaoWu LIU XiaoMing | 2008 | Chinese Science Bulletin2008,53,13: | 22 |
| 3 | The p53-induced lincRNA-p21 derails somatic cell reprogramming by sustaining H3K9me3 and CpG methylation at pluripotency gene promoters显示文摘最近的研究在众多的生物过程增加了我们长 noncoding RNA (lncRNAs ) 的理解,但是很少在体的房间 reprogramming 检验了他们的角色。通过表示介绍并且功能的屏蔽,我们鉴别了大 intergenic noncoding RNA p21 (lincRNA-p21 ) 损害 reprogramming。尤其是, lincRNA-p21 被 p53 导致,但是不在 reprogramming 支持 apoptosis 或房间老朽。相反, lincRNA-p21 与 H3K9 methyltransferase SETDB1 和维护 DNA methyltransferase DNMT1 联系,它被 RNA 有约束力的蛋白质 HNRNPK 便于。因而, lincRNA-p21 由在 pluripotency 基因倡导者支撑 H3K9me3 或 CpG methylation 阻止 reprogramming。我们的结果在 reprogramming 提供卓见进 lncRNAs 的角色并且建立在 p53 和 heterochromatin 规定之间的一个新奇连接。 | Xichen Bao Haitao Wu Xihua Zhu Xiangpeng Guo Andrew P Hutchins Zhiwei Luo Hong Song Yongqiang Chen Keyu Lai Menghui Yin Lingxiao Xu Liang Zhou Jiekai Chen Dongye Wang Baoming Qin Jon Frampton Hung-Fat Tse Duanqing Pei Huating Wang Biliang Zhang Miguel A Esteban | 2015 | Cell Research2015,25,1: | 21 |
| 4 | A peculiar composite M-and W-type REE tetrad effect:Evidence from the Shuiquangou alkaline syenite complex,Hebei Province,China显示文摘A new type of REE tetrad effect,a composite M-and W-type,was recognized in the K-feldsparthized and silicificated Shuiquangou alkaline syenites,Dongping,Hebei Province.Different analytical methods such as ICP-MS and isotopic dilution thermal ion mass spectrometer were exploited to verify the REE concentrations of the samples in three laboratories in China,France and Korea.The results are reliable and consistent within errors.In situ quantitative analysis of REE concentrations of individual zircons and apatites extracted from the very same sample has shown that fractional crystallization of magma and the superimposed hydrothermal alteration might have taken place in at least two-stage hydrothermal activities to generate the composite M-and W-type REE tetrad effect.The coexisting melt and aqueous phases,the superimposed alteration by volatile(Cl,CO2) -and Si,K, Al-enriched high temperature hydrothermal fluids might be the important facts for this new MW-type of REE tetrad effect.In addition,the peculiar MW-type tetrad effect might be an indicator for Au mineralization of reworked plutons. | ZHAO ZhenHua BAO ZhiWei QIAO YuLou | 2010 | Chinese Science Bulletin2010,55,24: | 19 |
| 5 | Single-shot BOTDA based on an optical chirp chain probe wave for distributed ultrafast measurement显示文摘Brillouin optical time-domain analysis(BOTDA)requires frequency mapping of the Brillouin spectrum to obtain environmental information(e.g.,temperature or strain)over the length of the sensing fiber,with the finite frequencysweeping time-limiting applications to only static or slowly varying strain or temperature environments.To solve this problem,we propose the use of an optical chirp chain probe wave to remove the requirement of frequency sweeping for the Brillouin spectrum,which enables distributed ultrafast strain measurement with a single pump pulse.The optical chirp chain is generated using a frequency-agile technique via a fast-frequency-changing microwave,which covers a larger frequency range around the Stokes frequency relative to the pump wave,so that a distributed Brillouin gain spectrum along the fiber is realized.Dynamic strain measurements for periodic mechanical vibration,mechanical shock,and a switch event are demonstrated at sampling rates of 25 kHz,2.5 MHz and 6.25 MHz,respectively.To the best of our knowledge,this is the first demonstration of distributed Brillouin strain sensing with a wide-dynamic range at a sampling rate of up to the MHz level. | Dengwang Zhou Yongkang Dong Benzhang Wang Chao Pang Dexin Ba Hongying Zhang Zhiwei Lu Hui Li Xiaoyi Bao | 2018 | Light(Science & Applications)2018,7,1: | 11 |

Methods: The clinical and pathological data of 120 patients with pancreatic head cancer who had undergone TMpE in our center from May 2010 to January 2014 were retrospectively analyzed. Results: The mean operative time was(275.0±50.2) min and the average intra-operative blood loss was(390.0±160.5) mL. Post-operative complications were reported in 45 patients, while no peri-operative death was noted. The specimen margins were measured in three dimensions, and 86 patients(71.6%) achieved R0 resection. Conclusions: TMpE is safe and feasible for pancreatic head cancer and is particularly helpful to increase the R0 resection rate. | Wenguang Wu Xu'an Wang Xiangsong Wu Maolan Li Hao Weng Yang Cao Ruifa Bao Sijun Su Jianhua Lu Wei Gong Weibin Shi Jun Gu Xuefeng Wang Yingbin Liu Zhiwei Quan Shuyou Peng | 2016 | Chinese Journal of Cancer Research2016,28,4: | 10 |
| 7 | Desulfurization kinetics of ZnO sorbent loaded on semi-coke support for hot coal gas显示文摘Zn-based sorbent (Z20SC) prepared through semi-coke support in 20 wt% zinc nitrate solution by high-pressure impregnation presents an excellent desulfurization capacity in hot coal gas,in which H2 S can not be nearly detected in the outlet gas before 20 h breakthrough time.The effects of the main operational conditions and the particle size of Z20SC sorbent on its desulfurization performances sorbent were investigated in a fixed-bed reactor and the desulfurization kinetics of Z20SC sorbent removing H2 S from hot coal gas was calculated based on experimental data.Results showed that the conversion of Z20SC sorbent desulfurization reaction increased with the decrease of the particle size of the sorbent and the increases of gas volumetric flow rate,reaction temperature and H 2 S content in inlet gas.Z20SC sorbent obtained from hydrothermal synthesis by high-pressure impregnation possessed much larger surface area and pore volume than semi-coke support,and they were significantly reduced after the desulfurization reaction.The equivalent grain model was reasonably used to analyze experimental data,in which k s=4.382×10-3 exp(-8.270×103/RgT) and Dep=1.262×10-4exp(1.522×104/RgT).It suggests that the desulfurization reaction of the Z20SC sorbent is mainly controlled by the chemical reaction in the initial stage and later by the diffusion through the reacted sorbent layer. | Zhiwei Ma Xianrong Zheng Liping Chang Ruiyuan He Weiren Bao | 2012 | Journal of Natural Gas Chemistry2012,21,5: | 7 |
| 8 | Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes显示文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients. | Peinan Chen Xueke Zhao Fuyou Zhou Xin Song Shoujia Hu Yan Jin Xianzeng Wang Xuena Han ZongminFan Ran Wang Bei Li Wenli Han Panpan Wang Jilin Li Lixin Wan Liguo Zhang Qide Bao Fubao Chang Yanru Qin Zhiwei Chang Jianwei Ku Haijun Yang Ling Yuan Jingli Ren Xuemin Li Lidong Wang | 2020 | Cancer Biology & Medicine2020,17,1: | 6 |
| 9 | Multi-functional polyethersulfone nanofibrous membranes with ultra-high adsorption capacity and ultra-fast removal rates for dyes and bacteria显示文摘The adsorption technology has been widely applied in water remediation for contamination removal of dyes and bacteria,by virtue of the advantages of adsorption technology including high efficiency,energy conservation and ease of operation.Simultaneous removal of dyes and bacteria has been realized by some reported materials,but to achieve satisfactory adsorption amounts and rates remain an unmet goal for decades.Herein,a poly(methacrylatoethyl trimethyl ammonium chloride-co-methyl methacrylate)copolymer was synthesized,and then blended with polyethersulfone for the fabrication of nanofibrous membranes via electrospinning for the use of fast and massive removal of dyes and bacteria.Owing to the introduction of abundant quaternary ammonium groups,the maximum adsorption amount for methyl orange was up to 909.8 mg g^(-1).In addition,the modified nanofibrous membranes showed good recyclability,broad applications in severe environments,selective adsorption ability,and excellent dynamic removal performance.Especially,thanks to the abundant functional groups,the membranes showed fast adsorption ability for bacteria through electrostatic interaction.It should be noted that the clearance ratio for Staphylococcus aureus or Escherichia coli by 6 min of static adsorption could reach 93%or 90%for each.Additionally,dynamic removal ratio via filtration with the nanofibrous membranes could reach 99.7%for Staphylococcus aureus or 98.7%for Escherichia coli in 90 s.Therefore,the proposed approach towards the quaternary ammonium modified polyethersulfone nanofibrous membranes creates a new route for ultra-high adsorption capacity and ultra-fast removal rates for dyes and bacteria in water remediation. | Jianxu Bao Hang Li Yuanting Xu Shengqiu Chen Zhoujun Wang Chunji Jiang Huilin Li Zhiwei Wei Shudong Sun Weifeng Zhao Changsheng Zhao | 2021 | Journal of Materials Science & Technology2021,,19: | 4 |
| 10 | High-Q microresonators on 4H-silicon-carbide-on-insulator platform for nonlinear photonics显示文摘The realization of high-quality(Q)resonators regardless of the underpinning material platforms has been a ceaseless pursuit,because the high-Q resonators provide an extreme environment for confining light to enable observations of many nonlinear optical phenomenon with high efficiencies.Here,photonic microresonators with a mean Q factor of 6.75×10^(6)were demonstrated on a 4H-silicon-carbide-on-insulator(4H-SiCOI)platform,as determined by a statistical analysis of tens of resonances.Using these devices,broadband frequency conversions,including second-,third-,and fourth-harmonic generations have been observed.Cascaded Raman lasing has also been demonstrated in our SiC microresonator for the first time,to the best of our knowledge.Meanwhile,by engineering the dispersion properties of the SiC microresonator,we have achieved broadband Kerr frequency combs covering from 1300 to 1700nm.Our demonstration represents a significant milestone in the development of SiC photonic integrated devices. | Chengli Wang Zhiwei Fang Ailun Yi Bingcheng Yang Zhe Wang Liping Zhou Chen Shen Yifan Zhu Yuan Zhou Rui Bao Zhongxu Li Yang Chen Kai Huang Jiaxiang Zhang Ya Cheng Xin Ou | 2021 | Light(Science & Applications)2021,10,8: | 4 |

| 14 | Petrogenesis of the Payangazu Complex in Southern Mandalay, Central Myanmar and Its Tectonic Implications显示文摘The Payangazu complex in the central Myanmar is composed mainly of quartz diorite,granodiorite,and some synplutonic mafic dikes.The quartz diorite and granodiorite have zircon U-Pb ages of 130.5±4.0(MSWD=3.5)and 118.4±2.5 Ma(MSWD=2.4),respectively.Rock samples of the quartz diorite and granodiorite are metaluminous,enriched in large-ion lithophile elements like LREE,Rb,Th,and U,and depleted in high field-strength elements such as HREE,Nb,Ta,P,and Ti,indicative of arc-type magmatic affinities.Whole rock samples of the quartz diorite haveε_(Hf)(t)value of+0.6,initial ^(87)Sr/^(86)Sr ratios of 0.708 6 to 0.710 0,andε_(Nd)(t)values of-4.8 to-4.9;whereas rocks of the granodiorite are relatively isotopically enriched,withε_(Hf)(t)values of-5.1 to-7.2,initial ^(87)Sr/^(86)Sr ratios of 0.711 7 to 0.711 8,andε_(Nd)(t)values of-8.7 to-8.8.The isotopic data together with the high Mg~#(both the quartz diorite and granodiorite have Mg~#values of>40)suggest a strong involvement of mantle materials in the genesis of the parent magmas.The possible petrogenetic process may be that the ascending of melts from partial melting of metasomatized mantle wedge triggered by dehydration of subducted slab resulted in partial melting of the lower crust and mixed with the latter.These Early Cretaceous intrusions from the complex are older than those found in the eastern Wuntho-Popa arc in western Myanmar,eastern Himalaya,and western Yunnan which are interpreted to be related to the Neo-Tethyan subduction,and haveε_(Nd)(t),ε_(Hf)(t)values lower than the latter.On the contrary,the ages and geochemical characteristics of the Payangazu complex are consistent with some of the intrusions in the northern magmatic belt in Tibet,eastern Himalaya,and western Yunnan which are believed to be associated with the subduction of the Bangong-Nujiang Ocean crust.Thus,we propose that the Early Cretaceous intrusions in the central Myanmar are most likely related to the southward subduction of an ocean slab that was possibly an extension of the Bangong-Nujiang Ocean. | Kaixuan Li Huaying Liang Zhiwei Bao Wenting Huang Jian Zhang Long Ren | 2019 | Journal of Earth Science2019,30,1: | 2 |
| 15 | Tailoring thermal conductivity of bulk graphene oxide by tuning the oxidation degree显示文摘Bulk graphene oxide(GO) shows great potential in a variety of applications, such as sensors,photodetectors, supercapacitors, lithium ion batteries and catalysts. However, its thermal conductivity,one of the most important and fundamental physical properties, is still less known. Herein, we have systematically investigated the thermal conductivity of bulk GOs and find that it can be tailored by tuning their oxidation degree during preparation process. Notably, the cross-plane thermal conductivity of bulk GO, in comparison with its precursor graphite, exhibits more than 100 times decrease at room temperature. The dependence of thermal conductivity of GO on oxidation degree is attributed to the chemical and structural changes by introducing oxygen atoms and oxygen-containing functional groups,which can lead to a significant enhancement in atomic-and nano-scale phonon scattering. Furthermore,we reveal that the thermal conductivity of bulk GOs exhibits evident anisotropic behavior. These results provide fundamental understanding and valuable information on thermal transport properties of bulk GOs for various practical applications. | Qing-Long Meng Hengchang Liu Zhiwei Huang Shuang Kong Peng Jiang Xinhe Bao | 2018 | Chinese Chemical Letters2018,29,5: | 2 |
| 16 | Geochemistry and geodynamic significance of the rare-earth mineralized Paleoproterozoic Longwangzhuang granite on the southern margin of the North China Craton显示文摘The Longwangzhuang granite pluton occurs on the southern margin of the North China Craton and consists mainly of biotite syenogranite with aegirine granite being locally distributed.The granites are characterized by high silicon and alkaline contents(SiO2=72.17%-76.82%,K2O+Na2O=8.28%-10.22%,K2O/Na2O>>1),AI(agpaitic index) =0.84-0.95,DI=95-97,ASI(aluminum saturation index)=0.96-1.13,and very high Fe* number(FeO*/(FeO*+Mg)=0.90-0.99),thus the granites are assigned to the metaluminous to weakly peraluminous,alkalic to calc-alkalic ferroan A-type granites.The granites are rich in large ion lithophile elements(LILE),especially high in REE concentrations(REE+Y=854×10-6-1572×10-6);whereas the enrichment of high strength field elements(Nb,Ta,Zr,Hf) is obviously less than that of LILEs,exhibiting mild depletions on trace element spider plots;and the rocks are significantly depleted in Ba,Sr,Ti,and Pb.The low εNd(t) values(-4.5--7.2) and high model ages(2.3-2.5 Ga) of the granites as well as the low εHf(t) values(-1.11--5.26) and high Hf model ages(THf1= 2.1-2.3 Ga,THf2=2.4-2.6 Ga) of zircons from the biotite syenogranite suggest that the granites were probably derived from an enriched mantle source.The zircons from the biotite syenogranite are mainly colorless transparent crystals exhibiting well-developed oscillatory zoning on the cathodoluminescence images with a LA-ICPMS zircon U-Pb age of 1602.1±6.6 Ma(MSWD=0.48).Petrochemical,trace elements,as well as Nd and Hf isotopic compositions of the rocks demonstrate that the granites were formed in a within-plate extensional tectonic regime possibly related to the breakup of the Columbia supercontinent.The granites were most likely formed through extreme fractional crystallization of alkali basaltic magma resulted from partial melting of the mantle,which was fertilized by recycling crustal rocks triggered by the delamination of lithospheric mantle and lower crust following the ~1.8 Ga collision and amalgamation of the North China Craton which is part of the Columbia supercontinent.However,contamination of neo-Archean to Paleoproterozoic crustal rocks during the ascent and emplacement of the magma could not be excluded.Being the youngest known anorogenic magmatism on the southern margin of the North China Craton related to Columbia breakup,it might represent the break off of the North China Craton from Columbia supercontinent at the end of Paleoproterozoic. | Bao, Zhiwei Wang, Qiang Du, Fengjun | 2011 | Chinese Journal Of Geochemistry2011,30,2: | 2 |

| 18 | Selective potassium uptake via biocompatible zeolite–polymer hybrid microbeads as promising binders for hyperkalemia显示文摘Patients with chronic kidney disease are at high risk of hyperkalemia that is associated with various lifethreatening complications.Treatments primarily rely on orally administered potassium binding agents,along with low curative effects and various side effects.Herein,direct serum potassium uptake was realized via zeolite–heparin-mimicking-polymer hybrid microbeads.The preparation process involved the synthesis of the heparin-mimicking polymer via the in situ cross-linking polymerization of acrylic acid and N-vinylpyrrolidone in polyethersulfone solution,the fabrication of microbeads via zeolite-mixing,electro-spraying and phase-inversion,and the subsequent aqueous-phase modifications based on ion-exchange and metal-leaching.An ultra-high(about 88%)amount of zeolite could be incorporated and well locked inside the polymer matrix.Potassium uptake capability was verified in water,normal saline and human serum,showing high selectivity and fast adsorption.The microbeads exhibited satisfying blood compatibility,negligible hemolysis ratio,prolonged clotting time,inhibited contact activation,and enhanced antifouling property toward serum proteins and cells.The proposed approach toward zeolite–heparin-mimicking-polymer hybrid microbeads provided a cheap,efficient and safe treatment protocol of hyperkalemia for the high-risk patients. | Zhoujun Wang Wei Sun Zhiwei Wei Jianxu Bao Xin Song Yupei Li Haifeng Ji Jue Zhang Chao He Baihai Su Weifeng Zhao Changsheng Zhao | 2021 | Bioactive Materials2021,6,2: | 2 |
| 19 | Metallogeny of the Lannigou Sedimentary Rock-hosted Disseminated Gold Deposit in Southwestern Guizhou Province,China显示文摘The Lannigou deposit is a large-sized sedimentary rock-hosted disseminated gold (SRHDG) deposit located in the Youjiang Basin. It is hosted by the Middle Triassic turbidite. Wall rock alterations, including silicification, pyritization, arsenopyritization, carbonatization and argillization, commonly occur along fractures. PGE study demonstrates that either Permian basalts or Triassic ultrabasic intrusives are unlikely to be the main source of gold mineralization. Coupled with the lack of other magmatic activity in the vicinity of the mining area, an amagmatic origin is proposed. Organic matter compositions and GC-MS analysis of the ores and host rocks show that the organics in the ores and the host rocks have a common source; the organic matter in the ores was mainly indigenous. The positive correlation between S2 and Au contents, along with the common occurrence of organic inclusions, suggest involvement of organic matter in the ore-forming process in terms of promoting Au leaching from the source rocks, making colloidal Au migration possible, as well as hydrocarbon reduction of sulphate. Geological and geochemical characteristics of the Lannigou deposit suggest that it was formed through circulation of meteoric water and probably less importantly organic bearing formation water driven by high geothermal gradient caused by late Yanshanian extension, which leached Au from the source bed, and then migrated as Au-bisulfides and colloidal Au, culminating in deposition by reduction-adsorption and surface complexation of gold onto the growth surface of arsenian pyrite. | BAO Zhiwei Jayanta GUHA | 2007 | Acta Geologica Sinica(English Edition)2007,81,1: | 2 |
