| 1 | Petrogenesis of highly fractionated I-type granites in the Zayu area of eastern Gangdese, Tibet: Constraints from zircon U-Pb geochronology, geochemistry and Sr-Nd-Hf isotopes显示文摘The Cretaceous granitoids in the middle and northern Gangdese, Tibet are generally interpreted as the products of anatexis of thickened deep crust genetically associated with the Lhasa-Qiangtang collision. This paper reports bulk-rock major element, trace element and Sr-Nd isotopic data, zircon U-Pb age data, and zircon Hf isotopic data on the Zayu pluton in eastern Gangdese, Tibet. These data shed new light on the petrogenesis of the pluton. Our SHRIMP zircon U-Pb age dates, along with LA-ICPMS zircon U-Pb age dates recently reported in the literature, indicate that the Zayu pluton was emplaced at about 130 Ma, coeval with Early Cretaceous magmatic rocks in other areas of eastern Gangdese (e.g., Rawu, Baxoi areas) and the Middle Gangdese. The Zayu pluton samples lack amphibole and muscovite, and are compositionally characterized by high SiO2 (69.9%―76.8%), K2O (4.4%―5.7%), and low P2O5 (0.05%―0.12%). These samples also have A/CNK values of 1.00-1.05, and are enriched in Rb, Th, U, and Pb, and depleted in Ba, Nb, Ta, Sr, P, Ti, and Eu. These geochemical features suggest that the Zayu pluton samples are metaluminous to slightly peraluminous and are of highly fractionated I-type granite. The Zayu pluton samples have high εNd(t) values (-10.9--7.6) and low initial 87Sr/86Sr ratios (0.7120- 0.7179) relative to melts derived from mature continental crust in the Gangdese (e.g., Ningzhong Early Jurassic strongly peraluminous granite). The Zayu pluton samples are heterogeneous in zircon εHf(t) values (-12.8--2.9), yielding ancient zircon Hf crustal model ages of 1.4―2.0 Ga. The data obtained in this study together with the data in the recent literature suggest that the Early Cretaceous granitoids in eastern Gangdese represent the eastward extension of the Early Cretaceous magmatism in the middle Gangdese, and that the Lhasa micro-continent block with ancient basement may extend for ~2000 km from east to west. Zircon Hf isotopic data and bulk-rock zircon saturation temperature (789-821℃) indicate that mantle-derived materials likely played a role in the generation of the Zayu pluton. We propose that the Zayu pluton was most likely generated in a setting associated with southward sub- duction of the Bangong-Nujiang ocean floor, where mantle wedge-derived magmas may have providedthe heat and material for the anatexis of ancient crust of the Lhasa micro-continent, resulted in hybrid melts (i.e., mantle-derived basaltic magmas + crust-derived felsic magmas). Such hybrid melts with subsequent fractional crystallization are responsible for the highly evolved Zayu pluton (crust thick- ening is not a prerequisite). | ZHU DiCheng MO XuanXue WANG LiQuan ZHAO ZhiDan NIU Yaoling ZHOU ChangYong YANG YueHeng | 2009 | Science China Earth Sciences2009，52，9： | 107 |
| 2 | Emplacement age of the Tahe granite and its constraints on the tectonic nature of the Ergun block in the northern part of the Da Hinggan Range显示文摘Large-scale granitic plutons are exposed in the Ergun block in the northern part of the Da Hinggan Range, but their emplacement age and petrogenesis remain un-known. Of these plutons, the Tahe pluton is composed mainly of porphyritic syenogranite and monzogranite, with minor hornblende alkali feldspar granite and gabbro, which have affinities to post-orogenic granitoids. Laser-ablation Induc-tively Coupled Plasma Mass-spectroscope (LA-ICP-MS) analysis shows that the major rock types of the Tahe pluton formed at 494-480 Ma ago, indicating its emplacement in the Early Paleozoic. It is concluded, therefore, that the colli-sion between the Ergun and the Xing’an blocks ended in Early Paleozoic. Considering the geochronological data of the plutons in the adjacent areas, the Early Paleozoic evolu-tionary history of the Ergun block is similar to the central Mongolia and the Tuvino blocks in Mongolia, and the Ergun block should be a part of the accretionary continental mar-gin in the southern Siberian Craton. | GE Wenchun WU Fuyuan ZHOU Changyong Abdel Rahman A.

| 6 | Leukocyte Membrane-Coated Liquid Metal Nanoswimmers for Actively Targeted Delivery and Synergistic Chemophotothermal Therapy显示文摘We report a leukocyte membrane-coated gallium nanoswimmer(LMGNS)capable of ultrasound-propelled motion,antibiofouling,and cancer cell recognition and targeting.The LMGNS consists of a needle-shaped gallium core encapsulating an anticancer drug and a natural leukocyte membrane shell.Under the propulsion of an ultrasound field,LMGNSs could autonomously move in biological media with a speed up to 108.7μms^(-1).The velocity and motion direction of the LMGNSs can be modulated by regulating the frequency and voltage of the applied ultrasound field.Owing to the leukocyte membrane coating,LMGNSs can not only avoid biofouling during the motion in blood but also possess cancer cell recognition capability.These LMGNSs could actively seek,penetrate,and internalize into the cancer cells and achieve enhanced anticancer efficiency by combined photothermal and chemical therapy.Such biofunctionalized liquid metal nanoswimmer presents a new type of multifunctional platform for biomedical applications. | Daolin Wang Changyong Gao Chang Zhou Zhihua Lin Qiang He | 2020 | Research2020，，1： | 8 |
| 7 | Growth of LaBr_3:Ce^(3+) Single Crystal by Vertical Bridgman Process in Nonvacuum Atmosphere显示文摘The growth of LaBr3:Ce3+ crystal by the vertical Bridgman process in a nonvacuum atmosphere was reported. According to the dehydration procedure of LaBr3·7H2O and CeBr3·7H2O investigated by differential thermal analysis/thermogravimetry (DTA/TG), anhydrous LaBr3 and CeBr3 were prepared by heating LaBr3·7H2O and CeBr3·7H2O at 240–260°C for 5–6 h in dried HBr atmosphere. Using the feed materials prepared from the anhydrous lanthanon bromides, a 0.5 mole fraction Ce3+ doped LaBr3 crystal with size of φ25 mm×50 mm had been grown by vertical Bridgman process successfully. By sealing the feed material in a platinum crucible, the crystal could be grown in a nonvacuum atmosphere as the oxidization and volatilization of the melt could be avoided. The crystal was grown with the optimum conditions such as a growth rate of 0.5–1.0 mm/h and a temperature gradient of around 30°C/cm across solid-liquid interface under a furnace temperature of 850–880°C. The crystal was characterized by DTA/TG, X-ray diffraction (XRD), optical transmission, photoluminescence and X-ray stimulated luminescence measurement. The Bridgman process was confirmed to be promising for growing transparent LaBr3:Ce3+ crystal with high optical quality. | Hongbing Chen Changyong Zhou Peizhi Yang Jinhao Wang | 2009 | Journal of Materials Science & Technology2009，25，6： | 6 |
| 8 | Monoclonal antibody-based serological methods for detecting Citrus tristeza virus in citrus groves显示文摘Citrus tristeza virus(CTV) is one of the most economically important citrus viruses and harms the citrus industry worldwide.To develop reliable and effective serological detection assays of CTV,the major capsid protein(CP) gene of CTV was expressed in Escherichia coli BL21(DE3) using the expression vector p ET-28 a and purified through Ni^+-NTA affinity chromatography.The recombinant protein was used to immunize BALB/c mice.Four hybridoma cell lines(14B10,14H11,20D5,and20G12) secreting monoclonal antibodies(MAbs) against CTV were obtained through conventional hybridoma technology.The titers of MAb-containing ascitic fluids secreted by the four hybridoma lines ranged from 10-6 to 10-7 in indirect enzyme-linked immunosorbent assay(ELISA).Western blots showed that all four MAbs could specifically react with CTV CP.Using the prepared MAbs,dot-ELISA,Tissue print-ELISA,and triple antibody sandwich(TAS)-ELISA were developed to detect CTV in tree nurseries and epidemiological studies.The developed dot-ELISA and TAS-ELISA methods could detect CTV in crude extracts of infected citrus leaves with dilutions of 1:2560 and1:10,240(w/v,g/m L),respectively.Tissue print-ELISA was particularly useful for large-scale field sample detection,mainly owing to its simplicity and lack of sample preparation requirements.The field survey revealed that CTV is prevalent on citrus trees in the Chongqing Municipality,Jiangxi Province,and Zhejiang Province of China.The coincidence rate of serological and RT-PCR test results reached more than 99.5%.The prepared MAbs against CTV and established sensitive and specific serological assays have a significant role in the detection and prevention and control of CTV in our country. | Zhen Liu Zhe Chen Jian Hong Xuefeng Wang Changyong Zhou Xueping Zhou Jianxiang Wu | 2016 | Virologica Sinica2016，31，4： | 5 |
| 9 | A comparative study on different regeneration processes of Pt-Sn/γ-Al2O3 catalysts for propane dehydrogenation显示文摘Three different regeneration processes including hydrogen or nitrogen purging and coke-burning treatment were used to restore the Pt-Sn/γ-Al_2O_3 catalysts, through which propane dehydrogenation reaction was performed in a consecutive reaction-regeneration mode. It was found that the catalyst using hydrogen regeneration showed the best stability compared with those regenerated by nitrogen purging and coke-burning treatment, suggesting that hydrogen regeneration is an effective approach for maintaining the performance of Pt-Sn/γ-Al_2O_3 catalysts in propane dehydrogenation reaction. The effect of different regeneration atmospheres on the metal active center and the coke deposition was investigated by XRD,TEM, N_2-physisorption, TPO, TG and Raman technologies, and the results revealed that hydrogen or nitrogen regeneration resulted in little impact on the size and structure of metal active center, retaining the effective Pt Sn phase over the catalyst. Moreover, hydrogen regeneration not only removed the low dense components of the coke, but also altered the property of the residual coke through hydrogenation, leading to a higher mobility of coke, and thus a higher accessibility of the metal active centers. Whereas nitrogen regeneration only removed the low dense components of the coke. Although coke-burning regeneration caused a thorough coke removal, the catalyst subjected to repeated redox exhibited poor stability due to metal agglomeration, phase segregation and the resulting large Pt_3Sn particle and core-shell structure with a Sn-rich surface. | Changyong Sun Junyin Luo Mingjin Cao Ping Zheng Guocheng Li Jiahao Bu Zhou Cao Shihong Chen Xiaowei Xie | 2018 | Journal of Energy Chemistry2018，27，1： | 5 |
| 10 | Detection of Citrus yellow vein clearing virus by Quantitative Real-time RT-PCR显示文摘To develop a rapid and reliable detection method for Citrus yellow vein clearing virus(CYVCV), a quantitative real-time reverse transcriptionpolymerase chain reaction(q RT-PCR) system based on SYBR Green I was established by using a pair of specific primers designed from its conserved coat protein gene. The sensitivity, specificity, and applicability of the system were evaluated accordingly. The results showed that amplicons were produced from CYVCV isolates, whereas no amplicons from non-CYVCV citrus virus samples, including Citrus tristeza virus(CTV) and Citrus tatter leaf virus(CTLV), were obtained. The sensitivity of the q RT-PCR was 100-fold higher than that of conventional RT-PCR. An excellent linear correlation(R2= 0.999) was obtained from two standard curves of c RNA, and the amplification efficiency was 102%. The data from field citrus samples detection showed that the q RT-PCR system could be used in determining the concentration of CYVCV in different citrus species. | CHEN Hongming ZHOU Yan WANG Xuefeng ZHOU Changyong YANG Xiuyan LI Zhongan | 2016 | Horticultural Plant Journal2016，2，4： | 4 |
| 11 | Palaeoecological Analysis of Trace Fossil Sinusichnus sinuosus from the Middle Triassic Guanling Formationin Southwestern China显示文摘The Luoping Biota discovered from the early Middle Triassic(Anisian) Guanling Formation of southwestern China represents a fully recovered shallow marine ecosystem, marking the end point of Early Triassic biotic recovery following the end-Permian mass extinction. Contemporaneously preserved are prolific trace fossils, which offer good opportunities to understand the palaeoecology of marine invertebrates from a fully recovered shallow marine ecosystem. Here we present a newly discovered sinuous branching burrow from the fossil-bearing unit in Member II of the Guanling Formation. Several features, including the horizontal regular sinuous nature, the branching pattern, typical H-junction, and the small wavelength/amplitude ratio of these sinuous structures within the burrow systems justify assignment of these traces as Sinusichnus sinuosus, a trace possibly produced by decapod crustaceans. Close association of S. sinuosus with Rhizocorallium commune suggests a deposit-feeding strategy of these trace makers. The newly reported Anisian material from the Guanling Formation in Luoping represents first report of Sinusichnus from South China. The global record of Sinusichnus occurrence suggests that these burrows might have an older history than Early Middle Triassic. | Mao Luo Yi-Ming Gong G. R.

| 12 | Embryoid bodies formation and differentiation from mouse embryonic stem cells in collagen/Matrigel scaffolds显示文摘Embryonic stem (ES) cells have the potential to develop into any type of tissue and are considered as a promising source of seeding cells for tissue engineering and transplantation therapy.The main catalyst for ES cells differentiation is the growth into embryoid bodies (EBs),which are utilized widely as the trigger of in vitro differentiation.In this study,a novel method for generating EBs from mouse ES cells through culture in collagen/Matrigel scaffolds was successfully established.When single ES cells were seeded in three dimensional collagen/Matrigel scaffolds,they grew into aggregates gradually and formed simple EBs with circular structures.After 7 days' culture,they formed into cystic EBs that would eventually differentiate into the three embryonic germ layers.Evaluation of the EBs in terms of morphology and potential to differentiate indicated that they were typical in structure and could generate various cell types;they were also able to form into tissue-like structures.Moreover,with introduction of ascorbic acid,ES cells differentiated into cardiomyocytes efficiently and started contracting synchronously at day 19.The results demonstrated that collagen/Matrigel scaffolds supported EBs formation and their subsequent differentiation in a single three dimensional environment. | Jin Zhou Ye Zhang Qiuxia Lin Zhiqiang Liu Haibin Wang Cuimi Duan Yanmeng Wang Tong Hao Kmwu Wu Changyong Wang | 2010 | Journal of Genetics and Genomics2010，37，7： | 4 |
| 13 | Distribution and characteristics of telocytes as nurse cells in the architectural organization of engineered heart tissues显示文摘Interstitial Cajal-like cells are a distinct type of interstitial cell with a wide distribution in mammalian organs and tissues,and have been given the name'telocytes'.Recent studies have demonstrated the potential roles of telocytes in heart development,renewal,and repair.However,further research on the functions of telocytes is limited by the complicated in vivo environment.This study was designed to construct engineered heart tissue(EHT)as a three-dimensional model in vitro to better understand the role of telocytes in the architectural organization of the myocardium.EHTs were constructed by seeding neonatal cardiomyocytes in collagen/Matrigel scaffolds followed by culture under persistent static stretch.Telocytes in EHTs were identified by histology,toluidine blue staining,immunofluorescence,and transmission electron microscopy.The results from histology and toluidine blue staining demonstrated widespread putative telocytes with compact toluidine blue-stained nuclei,which were located around cardiomyocytes.Prolongations from the cell bodies showed a characteristic dichotomous branching pattern and formed networks in EHTs.Immunofluorescence revealed positive staining of telocytes for CD34 and vimentin with typical moniliform prolongations.A series of electron microscopy images further showed that typical telocytes embraced the cardiomyocytes with their long prolongations and exhibited a marked appearance of nursing cardiomyocytes during the construction of EHTs.This finding highlights the great importance of telocytes in the architectural organization of EHTs.It also suggests that EHT is an appropriate physical and pathological model system in vitro to study the roles of telocytes during heart development and regeneration. | ZHOU Jin WANG Yan ZHU Ping SUN HongYu MOU YongChao DUAN CuiMi YAO AnNing LV ShuangHong WANG ChangYong | 2014 | Science China(Life Sciences)2014，57，2： | 4 |

| 15 | Microbially Induced Carbonate Precipitation in a Middle Triassic Microbial Mat Deposit from Southwestern China:New Implications for the Formational Process of Micrite显示文摘Lime mud(i.e.,micrite)is a major component of carbonate deposits.Various mechanisms(biotic versus abiotic)have been proposed for the formation of lime mud in Earth’s history.However,the detailed role that microbes play in the nucleation and subsequent precipitation of micrites remains to be resolved.Herein we undertook a detailed geobiological characterization of laminated lime mudstone from the Middle Triassic Guanling Formation in Yunnan Province,southwestern China.Morphological features,together with previous geobiological investigations,suggest that the laminated lime mudstones represent the former presence of microbial mats.These lime mudstones consist mainly of calcite,dolomite and quartz,with clay minerals and pyrites as subordinate components.In particular,micro-analysis shows copious nano-globules(65–878 nm)and capsule-shaped nano-rods in laminations.These low-Mg calcite nano-globule aggregates are closely associated with mucilaginous biofilms resembling extracellular polymeric substances(EPS).Nano-sized globules coalesce to form semi-euhedral micrite crystals.We suggest that a decaying hydrolytic destruction of the EPS by microbial communities within microbial mat leads to the precipitation of the nano-globules by enhancing alkalinity in local micro-environment.As an intermediate,these nano-globules further aggregate to form micrite crystals possibly through a dissolution-reprecipitation process. | Mao Luo Jitao Chen Wenkun Qie Jinyuan Huang Qiyue Zhang Changyong Zhou Wen Wen | 2021 | Journal of Earth Science2021，32，3： | 2 |
| 16 | Modulation of Beta Oscillations for Implicit Motor Timing in Primate Sensorimotor Cortex during Movement Preparation显示文摘Motor timing is an important part of sensorimotor control. Previous studies have shown that beta oscillations embody the process of temporal perception in explicit timing tasks. In contrast, studies focusing on beta oscillations in implicit timing tasks are lacking. In this study, we set up an implicit motor timing task and found a modulation pattern of beta oscillations with temporal perception during movement preparation. We trained two macaques in a repetitive visually-guided reach-to-grasp task with different holding intervals. Spikes and local field potentials were recorded from microelectrode arrays in the primary motor cortex, primary somatosensory cortex, and posterior parietal cortex. We analyzed the association between beta oscillations and temporal interval in fixedduration experiments(500 ms as the Short Group and1500 ms as the Long Group) and random-duration experiments(500 ms to 1500 ms). The results showed that the peak beta frequencies in both experiments ranged from15 Hz to 25 Hz. The beta power was higher during the hold period than the movement(reach and grasp) period.Further, in the fixed-duration experiments, the mean poweras well as the maximum rate of change of beta power in the first 300 ms were higher in the Short Group than in the Long Group when aligned with the Center Hit event. In contrast, in the random-duration experiments, the corresponding values showed no statistical differences among groups. The peak latency of beta power was shorter in the Short Group than in the Long Group in the fixed-duration experiments, while no consistent modulation pattern was found in the random-duration experiments. These results indicate that beta oscillations can modulate with temporal interval in their power mode. The synchronization period of beta power could reflect the cognitive set maintaining working memory of the temporal structure and attention. | Hongji Sun Xuan Ma Liya Tang Jiuqi Han Yuwei Zhao Xuejiao Xu Lubin Wang Peng Zhang Luyao Chen Jin Zhou Changyong Wang | 2019 | Neuroscience Bulletin2019，35，5： | 2 |
| 17 | Acoustophoretic Motion of Erythrocyte-mimicking Hemoglobin Micromotors显示文摘of main observation and conclusion Biocompatible micromotors have received increasing attention,due to their powerful motion,diverse functionalities and autonomous navigation in the field of biomedical applications.Herein,we report an acoustically-propelled,magnetic-guided,erythrocyte-mimicking hemoglobin micromotor with oxygen-carrying capability.These hemoglobin micromotors were fabricated by encapsulating magnetic nanoparticles in hybrid hemoglobin/calcium carbonate microparticles,followed by covalently layer-by-layer assembly of hemoglobin multilayers.The asymmetric distribution of magnetic nanoparticles enables these micromotors to move rapidly under the propulsion of an acoustic field.The velocity of acoustophoretic motion of hemoglobin micromotors increases with the increase of input voltage of acoustic field,up to 58.2 pirn s^-1 at 10 V.The hemoglobin micromotors are directionally navigated by applying an external magnetic field,and also could pass through microchannels toward the targeted region.Moreover,such hemoglobin micromotors show effective oxygen loading and releasing capability,holding considerable promise as a new platform for oxygen delivery applications. | Changyong Gao Zhihua Lin Chang Zhou Daolin Wang Qiang He | 2020 | Chinese Journal of Chemistry2020，38，12： | 1 |
| 18 | Recent Advances on Citrus yellow vein clearing virus in Citrus显示文摘Citrus yellow vein clearing virus(CYVCV)is the causal agent of yellow vein clearing disease,a significant and devastating disease of most citrus species including lemon and sour orange.CYVCV,a single-strand positive-sense RNA virus containing six ORFs(Open Reading Frames),represents a new species in the genus Mandarivirus of the Alphaflexiviridae family.The virus can cause particularly serious damage,resulting in reduced tree vigor,lower yields,and decreased marketability of fruit production,and it has been found in India,Turkey,Pakistan,China and Iran.Here we described the geographical distribution of the virus,its transmission mode by grafting,mechanical inoculation,and insects,as well as currently available techniques for detection.In addition,we also discussed practical measures aimed at controlling the disease and provided theoretical guidance to prevent the acquisition and spread of the disease that is a significant step toward ensuring the health of the citrus industry. | Cuihua Liu Hai Liu John Hurst Michael P Timko Changyong Zhou | 2020 | Horticultural Plant Journal2020，6，4： | 1 |
| 19 | Crystalline InGaZnO quaternary nanowires with superlattice structure for high-performance thin-film transistors显示文摘Amorphous indium-gallium-zinc oxide (a-IGZO) materials have been widely explored for various thin-film transistor (TFT) applications;however, their device performance is still restricted by the intrinsic material issues especially due to their non-crystalline nature. In this study, highly crystalline superlattice-structured IGZO nanowires (NWs) with different Ga concentration are successfully fabricated by enhanced ambient-pressure chemical vapor deposition (CVD). The unique superlattice structure together with the optimal Ga concentration (i.e., 31 at.%) are found to effectively modulate the carrier concentration as well as efficiently suppress the oxygen vacancy formation for the superior NW device performance. In specific, the In1.8Ga1.8Zn2.4O7 NW field-effect transistor exhibit impressive device characteristics with the average electron mobility of ~ 110 cm^2-V^-1·s^-1 and on/off current ratio of ~ 10^6. Importantly, these NWs can also be integrated into NW parallel arrays for the construction of high-performance TFT devices, in which their performance is comparable to many state-of-the-art IGZO TFTs. All these results can evidently indicate the promising potential of these crystalline superlattice-structured IGZO NWs for the practical utilization in next-generation metal-oxide TFT device technologies. | Fangzhou Li SenPo Yip Ruoting Dong Ziyao Zhou Changyong Lan Xiaoguang Liang Dapan Li You Meng Xiaolin Kang Johnny C.
