| 2 | Serial stimulated thyroglobulin measurements are more specific for detecting distant metastatic differentiated thyroid cancer before radioiodine therapy显示文摘Objective: Preablative stimulated thyroglobulin(ps-Tg) has the potential to be used in identifying distant metastatic differentiated thyroid carcinoma(DM-DTC), but its single level can be affected by remnant thyroid tissue and thyrotropin(TSH). The objective of this retrospective study was to evaluate the value of serial ps-Tg measurements in identifying DM-DTC specifically.Methods: A total of 317 DTC patients with serial measurements of ps-Tg, TSH and anti-Tg antibody were divided into M1(n=72) and M0(n=245) according to the presence of distant metastasis(DM) or not. The initial psTg measurement, with a corresponding TSH exceeding 30 μIU/m L, was marked as Tg1, and ps-Tg measured right before radioactive iodine(RAI) therapy was defined as Tg2, with a median interval of 8 days. ΔTg denotes Tg2–Tg1, and ΔTSH denotes TSH2–TSH1. Tg1, Tg2, ΔTg, and ΔTg/ΔTSH were tested for efficacy in identifying DM-DTC using receiver operating characteristic(ROC) curve analysis, and further compared with chest computed tomography(CT) and posttreatment whole-body RAI scan(Rx WBS).Results: Compared with single ps-Tg measurement(Tg1 or Tg2), both ΔTg and ΔTg/ΔTSH were more narrowly distributed around zero in the M0 group, which made their distribution in the M1 group more distinguished in a relatively dispersed way. ΔTg/ΔTSH manifested a higher accuracy(88.64%) and specificity(90.20%) in identifying DM-DTC than Tg1 or Tg2 measurements, with a much higher specificity than chest CT(90.20% vs. 66.00%) and a much higher sensitivity than Rx WBS(83.33% vs. 61.11%).Conclusions: Serial ps-Tg measurements even over as short an interval as 8 days hold incremental value in identifying DM-DTC. ΔTg/ΔTSH is a specific early biochemical marker for DM-DTC. | Teng Zhao Jun Liang Tianjun Li Wen Gao Yansong Lin | 2017 | Chinese Journal of Cancer Research2017，29，3： | 15 |
| 3 | Effect of sintering temperature in argon atmosphere on microstructure and properties of 3D printed alumina ceramic cores显示文摘Alumina ceramics with different sintering temperatures in argon atmosphere were obtained using stereolithography-based 3D printing.The effects of sintering temperature on microstructure and physical and mechanical properties were investigated.The results show that the average particle size,shrinkage,bulk density,crystallite size,flexural strength,Vickers hardness,and nanoindentation hardness increased with the increase in sintering temperature,whereas the open porosity decreased with increasing sintering temperature.No change was observed in phase composition,chemical bond,atomic ratio,and surface roughness.For the sintered samples,the shrinkage in Z direction is much greater than that in X or Y direction.The optimum sintering temperature in argon atmosphere is 1350℃with a shrinkage of 3.0%,3.2%,and 5.5%in X,Y,and Z directions,respectively,flexural strength of 26.7 MPa,Vickers hardness of 198.5 HV,nanoindentation hardness of 33.1 GPa,bulk density of 2.5 g/cm^3,and open porosity of 33.8%.The optimum sintering temperature was 70℃higher than that sintering in air atmosphere when achieved the similar properties. | He LI Yongsheng LIU Yansong LIU Qingfeng ZENG Kehui HU Zhigang LU Jingjing LIANG | 2020 | Journal of Advanced Ceramics2020，9，2： | 13 |
| 4 | Magnetostratigraphic and paleoclimatic studies on the Red Earth Formation from the Chengdu Plain in Sichuan Province,China显示文摘Two red earth sections from the Chengdu Plain in Sichuan Province are dated using geomagnetic methods. The Brunhes/Matuyama (B/M) reversal boundary is recognized within the upper parts of the two sections,and the Jaramillo normal subzone occurs in the middle-lower parts of the vermiculated red soil (VRS),which indicate that the parent material for the VRS deposited in the middle Quaternary. Sedimentologic and geochemical studies suggest that the Chengdu Clay and part of the parent material for the VRS are of aeolian origin. Pollen analysis indicates that the Chengdu Plain was mainly covered by needle-leaved forest with a cool to cool temperate humid climate when the parent material for the VRS deposited. The relatively cool to cool temperate climatic condition in the Chengdu Plain in the middle Quaternary,which may be caused by the uplift of the Tibetan Plateau,was a response to the geo-environmental changes of global significance. | ZHAO ZhiZhong QIAO YanSong WANG Yan FU JianLi WANG ShuBing LI ChaoZhu YAO HaiTao JIANG FuChu | 2007 | Science China Earth Sciences2007，50，6： | 7 |
| 5 | Development and utilization of a new chemically-induced soybean library with a high mutation density显示文摘Mutagenized populations have provided important materials for introducing variation and identifying gene function in plants. In this study, an ethyl methanesulfonate(EMS)-induced soybean(Glycine max) population,consisting of 21,600 independent M_2 lines, was developed.Over 1,000 M_(4(5))families, with diverse abnormal phenotypes for seed composition, seed shape, plant morphology and maturity that are stably expressed across different environments and generations were identified. Phenotypic analysis of the population led to the identification of a yellow pigmentation mutant, gyl, that displayed significantly decreased chlorophyll(Chl) content and abnormal chloroplast development. Sequence analysis showed that gyl is allelic to Minn Gold, where a different single nucleotide polymorphism variation in the Mg-chelatase subunit gene(ChlI1a) results in golden yellow leaves. A cleaved amplified polymorphic sequence marker was developed and may be applied to marker-assisted selection for the golden yellow phenotype in soybean breeding. We show that the newly developed soybean EMS mutant population has potential for functional genomics research and genetic improvement in soybean. | Zhongfeng Li Lingxue Jiang Yansong Ma Zhongyan Wei Huilong Hong Zhangxiong Liu Jinhui Lei Ying Liu Rongxia Guan Yong Guo Longguo Jin Lijuan Zhang Yinghui Li Yulong Ren Wei He Ming Liu Nang Myint Phyu Sin Htwe Lin Liu Bingfu Guo Jian Song Bing Tan Guifeng Liu Maiquan Li Xianli Zhang Bo Liu Xuehui Shi Sining Han Sunan Hua Fulai Zhou Lili Yu Yanfei Li Shuang Wang Jun Wang Ruzhen Chang Lijuan Qiu | 2017 | Journal of Integrative Plant Biology2017，59，1： | 6 |

| 7 | Integrated Inspection of QoM, QoP, and QoS for AOI Industries in Metaverses显示文摘With the rapid development of information technologies such as digital twin, extended reality, and blockchain,the hype around 'metaverse' is increasing at astronomical speed. However, much attention has been paid to its entertainment and social functions. Considering the openness and interoperability of metaverses, the market of quality inspection promises explosive growth. In this paper, taking advantage of metaverses, we first propose the concept of Automated Quality Inspection(Auto QI), which performs integrated inspection covering the entire manufacturing process, including Quality of Materials, Quality of Manufacturing(Qo M), Quality of Products, Quality of Processes(Qo P), Quality of Systems, and Quality of Services(Qo S). Based on the scenarios engineering theory, we discuss how to perform interactions between metaverses and the physical world for virtual design instruction and physical validation feedback. Then we introduce a bottomup inspection device development workflow with productivity tools offered by metaverses, making development more effective and efficient than ever. As the core of quality inspection,we propose Quality Transformers to complete detection task,while federated learning is integrated to regulate data sharing.In summary, we point out the development directions of quality inspection under metaverse tide. | Yutong Wang Yonglin Tian Jiangong Wang Yansong Cao Shixing Li Bin Tian | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，12： | 5 |

The random walks are described by the interaction of single photons with cross-Kerr media.The proposed scheme can also be used to implement one-dimensional quantum random walks on an infinite line. | WANG Chuan LI YanSong HAO Liang | 2011 | Chinese Science Bulletin2011，56，20： | 5 |

| 10 | Deployment of Sensors in WSN: An Efficient Approach Based on Dynamic Programming显示文摘Efficient sensor node deployment is extremely important in wireless sensor networks. It earns great practical meanings through using fewer sensor nodes as far as possible to satisfy different requirements such as the requirement on coverage and overcoming the potential sensor node failures and the adverse influence from the environment. We propose an efficient approach for the deployment of sensor nodes in wireless networks, termed as EDSNDA, which is excellent in taking both the requirements of sensor coverage and network connectivity into consideration when minimizing the number of necessary sensor nodes to the best of its ability. We proposed a new coverage model of sensor node. Based on the sensor coverage model, we establish four dynamic programming models in four different practical situations, respectively. The algorithms are then proposed which are used for solving the corresponding dynamic programming models. The validity of the method is justified by simulation studies in which the method is compared with the current representative methods. The simulation results show that our method performs better than the other ones with fewer sensor nodes, better coverage and network connectivity result in the same circumstance. | LI Yongyan GAO Wen WU Chunming WANG Yansong | 2015 | Chinese Journal of Electronics2015，24，1： | 4 |
| 11 | 2017 Chinese expert consensus on the clinical application ofserum marker for thyroid cancer显示文摘In recent years, the clinical incidence of thyroid cancer has been increasing year by year, and its risk assessment and clinical management methods have also been accordingly modified and constantly improved. There are great differences between the clinical diagnostic and therapeutic modes and disease management of thyroid cancer employed by various medical institutions in China, particularly with regard to the clinical application of serum marker of thyroid cancer. To this end, the China Anti-Cancer Association Thyroid Cancer Specialized Committee Chinese Association of Thyroid Oncology organized this compilation of ExpertConsensus on Clinical Application of Serum Marker of Thyroid Cancer to help and impel relevant clinical institutions and professionals to standardize clinical diagnosis, treatment, and long-term management of thyroid cancer, and to properly utilize the serum marker for scientific auxiliary clinical diagnosis and assessment of thyroid cancer before and after operation. | Ming Gao Minghua Ge Qinghai Ji Ruochuan Cheng Hankui Lu Haixia Guan Wei Cui Li Gao Zairong Gao Lin Guo Zhuming Guo Tao Huang Xiaoming Huang Yansong Lin Qinjiang Liu Xin Ni Jianwu Qin Li Ren Zhongyan Shan Hui Sun Xudong Wang Zhengang Xu Yang Yu Bin Zhang DaiweiZhao Ying Zheng Jingqiang Zhu Xiangqian Zheng 无 | 2018 | Cancer Biology & Medicine2018，15，4： | 3 |
| 12 | Internal OH^(-)induced cascade quenching of upconversio n luminesce nee in NaYF4:Yb/Er nanocrystals显示文摘Internal hydroxyl impurity is known as one of the main detrimental factors affecting the upconversion(UC)efficiency of upconversion luminescence(UCL)nanomaterials.Different from surface'ligand-related emission quenching which can be effectively diminished by,e.g.,core'shell structure,internal hydroxyl is easy to be introduced in synthesis but difficult to be quantified and controlled.Therefore,it becomes an obstacle to fully understand the relevant UC mechanism and improve UC efficiency of nanomaterials.Here we report a progress in quantifying and large-range adjustment of the internal hydroxyl impurity in NaYF4 nanocrystals.By combining the spectroscopy study and model simulation,we have quantitatively unraveled the microscopic in teractions underlying UCL que nching between internal hydroxyl and the sensitizers and activators,respectively.Furthermore,the internal hydroxyl-involved UC dynamical process is interpreted with a vivid concept of'Survivor effect' i.e.;the shorter the migration path of an excited state,the larger the possibility of its surviving from hydroxyl-induced quenchi ng.Apart from the consist ent experimental results,this concept can be further evidenced by Monte Carlo simulation,which monitors the variation of energy migration step distribution before and after the hydroxyl introduction.The new quantitative insights shall promote the construction of highly efficient UC materials. | Yansong Feng Zhi Li Qiqing Li Jun Yuan Langping Tu Lixin Ning Hong Zhang | 2021 | Light(Science & Applications)2021，10，6： | 3 |
| 13 | Immune responses of a designed HIV-1 DNA vaccine on rhesus monkeys显示文摘An effective HIV-1 vaccine will be the ultimate solution for the prevention of HIV/AIDS, though HAART plays important roles in treating the disease. In this study, a large-scale recombinant DNA plasmid containing a designed HIV-1 multi-epitope- p24 chimeric gene was prepared and purified. Rhesus monkeys were then inoculated muscularly with the plasmid for four times in week 0, 4, 8 and 18. Whole blood was collected two weeks after the third and fourth inoculation, followed by serum and pe- ripheral blood mononuclear cell (PBMC) separation. The CTL activity and proliferation of PBMCs stimu- lated by macaque MHC-I-restricted HIV-1 CTL epi- tope peptide were analyzed by MTT and LDH release assay, respectively. Th1 cytokines in supernatant of cultured PBMC stimulated by HIV-1 CTL epitope peptide and anti-HIV-1 antibody in serum were as- sayed by ELISA. The results showed that increased CTL target-killing activity, higher secretion of Th1 cytokines (IFN-γ and IL-2) and promoted proliferative reaction of monkey PBMCs stimulated by HIV-1 CTL epitope peptide were detected in the immunization group inoculated by the recombinant DNA vaccine for three times, which were further enhanced by the fourth inoculation. At the same time, HIV-1 specific antibody in serum of immunized monkeys was higher than that in controls. We concluded that the designedHIV-1 DNA vaccine may induce HIV-1 specific cellular and humoral immunity on monkeys. | ZHANG Lishu JIN Ningyi SONG Yingjin SUN Yansong WANG Hong ZHAN Dawei MA Hewen SHANG Yupu JIN Hongtao HONG Baoqing LI Chang | 2006 | Chinese Science Bulletin2006，51，13： | 3 |
| 14 | Intensification of the East Asian Monsoon in Southern China at about300-400 kaBP Inferred from Eolian Deposits in the Middle-lower Reaches of the Yangtze River显示文摘In the East Asian monsoon region,eolian deposits widely distributed in the middle-lower reaches of the Yantgze River are among the best materials available for studies on Quaternary climate change in the subtropical zone of Southern China.Typical eolian deposits in this region include upper Xiashu Loess(XL) and underlying Vermiculated Red Soil(VRS) layers.In this paper,chronological and paleoclimatic studies are conducted on an eolian deposit sequence near Jiujiang(JJ) city in northern Jiangxi province.A magnetostratigraphic study,combined with optically stimulated luminescence(OSL) dating,is conducted on the JJ section and provides further evidence that eolian deposits in the middle-lower reaches of the Yangtze River have been formed since the late Early Pleistocene,and that the boundary age between the XL and VRS layers is about 300-400 kaBP.In grain-size records of the JJ section,the median grain-size and content of the >30 μm size fraction increase sharply after 300-400 kaBP,representing an East Asian winter monsoon intensification event.Further pollen analysis reveals differing pollen assemblages before and after 300-400 kaBP:there is an evident increase in plants adapted to grow in a warm humid environment after 300-400 kaBP,implying an increase in precipitation caused by intensification of the East Asian summer monsoon.Global ice volume and uplift of the Tibet Plateau(TP) are regarded as crucial factors influencing variations of the East Asian monsoon on a long-term scale.The deep-sea δ^(18)O record,which reflects variations in global ice volume,shows no obvious change after 300-400 kaBP.Moreover,the influence of global ice volume changes on the East Asian summer and winter monsoons is inverse;the global ice volume increase(decrease) implies a strengthened(weakened) winter monsoon and weakened(strengthened) summer monsoon.We therefore interpret the coupled intensifications of the East Asian summer and winter monsoons at about 300-400 kaBP to the uplift of the TP in the Middle Pleistocene.This climate event is also documented in eolian deposits from the southern margin of the Chinese Loess Plateau(CLP) and from the desert-loess transitional belt.However,it is not recorded in the loess-paleosol sequences from the central part of the CLP,thereby indicating differing climate responses to TP uplift in different regions,which requires further study. | QI Lin QIAO Yansong LI Yuehui WANG Yan PENG Shasha HE Zexin YANG Shuaibin HAN Chao ZHANG Xujiao | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 3 |
| 15 | Modified wavelet filtering algorithm applied to gyro servo technology for the improvement of test-precision显示文摘In order to improve the measurement-precision of the gyro,the gyro experiment is completed based on gyro servo technology.The error sources of gyro servo technology are analyzed in the process of measurement,and the impact of these error sources on measurement is evaluated.To eliminate interference signal existing in the sampled data of the measurement,a modified wavelet threshold filtering method is presented.The results of the simulation and measurement show that the estimation-precision of the proposed method is improvement remarkably compared with the fast Fourier transform method,and the calculation work is reduced compared with the conventional wavelet threshold filtering methods,furthermore,the phenomenon of a common threshold of 'killing' is solved thoroughly. | Yanbo Li Yu Liu Baoku Su Yansong Jiang | 2011 | Journal of Systems Engineering and Electronics2011，22，3： | 3 |

| 17 | Direct sound field separation method on holography surface显示文摘In order to simplify the process which aims at separating the coherent sources located at different sides of holography surface,a direct sound field separation method which only depends on the data of holography surface is proposed.Assume that the reconstruction surface is holography surface,according to the equivalent sources located at the spherical surface,there exists a relationship between the measured sound pressure and the calculated value based on equivalent source method.Then,the coherent sources are separated.Numerical simulation analyzes the separation results when the interference sources are pulsating ball source and simply supported steel sheet with forced oscillation,respectively.The separation method is validated by experiment with two loudspeakers.The results show that the proposed method has high accuracy to the two kinds of interference sources and high tolerate deviation. | MAO Jin XU Zhongming LI Shu HE Yansong ZHANG Zhifei | 2017 | Chinese Journal of Acoustics2017，36，1： | 2 |
| 18 | The small GTPase RABA2a recruits SNARE proteins to regulate the secretory pathway in parallel with the exocyst complex in Arabidopsis显示文摘Delivery of proteins to the plasma membrane occurs via secretion,which requires tethering,docking,priming,and fusion of vesicles.In yeast and mammalian cells,an evolutionarily conserved RAB GTPase activation cascade functions together with the exocyst and SNARE proteins to coordinate vesicle transport with fusion at the plasma membrane.However,it is unclear whether this is the case in plants.In this study,we show that the small GTPase RABA2a recruits and interacts with the VAMP721/722-SYP121-SNAP33 SNARE ternary complex for membrane fusion.Through immunoprecipitation coupled with mass spectrometry analysis followed by the validatation with a series of biochemical assays,we identified the SNARE proteins VAMP721 and SYP121 as the interactors and downstream effectors of RABA2a.Further expreiments showed that RABA2a interacts with all members of the SNARE complex in its GTP-bound form and modulates the assembly of the VAMP721/722-SYP121-SNAP33 SNARE ternary complex.Intriguingly,we did not observe the interaction of the exocyst subunits with either RABA2a or theSNARE proteins in several different experiments.Neither RABA2a inactivation affects the subcellular localization or assembly of the exocystnor the exocyst subunit mutant exo84b shows the disrupted RABA2a-SNARE association or SNARE assembly,suggesting that the RABA2a-SNARE-and exocyst-mediated secretory pathways are largely independent.Consistently,our live imaging experiments reveal that the two sets of proteins follow non-overlapping trafficking routes,and genetic and cell biologyanalyses indicate that the two pathways select different cargos.Finally,we demonstrate that the plant-specific RABA2a-SNARE pathway is essential for the maintenance of potassium homeostasis in Arabisopsis seedlings.Collectively,our findings imply that higher plants might have generated different endomembrane sorting pathways during evolution and may enable the highly conserved endomembrane proteins to participate in plant-specific trafficking mechanisms for adaptation to the changing environment. | Lei Pang Zhiming Ma Xi Zhang Yuanzhi Huang Ruili Li Yansong Miao Ruixi Li | 2022 | Molecular Plant2022，15，3： | 2 |
| 19 | Novel nanometer scaffolds regulate the biological behaviors of neural stem cells显示文摘Ideal tissue-engineered scaffold materials regulate proliferation, apoptosis and differentiation of cells seeded on them by regulating gene expression. In this study, aligned and randomly oriented collagen nanofiber scaffolds were prepared using electronic spinning technology. Their diameters and appearance reached the standards of tissue-engineered nanometer scaffolds. The nanofiber scaffolds were characterized by a high swelling ratio, high porosity and good mechanical properties. The proliferation of spinal cord-derived neural stem cells on novel nanofiber scaffolds was obviously enhanced. The proportions of cells in the S and G 2 /M phases noticeably increased. Moreover, the proliferation rate of neural stem cells on the aligned collagen nanofiber scaffolds was high. The expression levels of cyclin D1 and cyclin-dependent kinase 2 were increased. Bcl-2 expression was significantly increased, but Bax and caspase-3 gene expressions were obviously decreased. There was no significant difference in the differentiation of neural stem cells into neurons on aligned and randomly oriented collagen nanofiber scaffolds. These results indicate that novel nanofiber scaffolds could promote the proliferation of spinal cord-derived neural stem cells and inhibit apoptosis without inducing differentiation. Nanofiber scaffolds regulate apoptosis and proliferation in neural stem cells by altering gene expression. | Jihui Zhou Fuge Sui Meng Yao Yansong Wang Yugang Liu Feipeng Tian Qiang Li Xiaofeng He Lin Shao Zhiqiang Liu | 2013 | Neural Regeneration Research2013，8，16： | 2 |
| 20 | Thermal Behavior Analysis of Stacked-type Supercapacitors with Different Cell Structures显示文摘As a new energy storage element,supercapacitors have characteristics such as high power density,fast charge and discharge rates,green environmental protection,and long cycle life.Temperature is an important parameter of supercapacitors which significantly influences the stability of the supercapacitors.In this study,the finite element method is used to realize a coupling between a one-dimensional electrochemical model and a three-dimensional thermal model.Then,based on this model,the concept of limited cycle numbers is defined,and different unit quantities,unit size,and the effect of temperature under different temperature environments such as low temperature,room temperature,and high temperature on stacked-type supercapacitors is studied.Finally,stacked-type supercapacitors are compared with rolled-type supercapacitors considering the same cell size,density,and volume approximations.The simulation results show that the higher the number of packaging units,the lower is the limit cycle number.This phenomenon is more pronounced under high current than under low current conditions.Increasing the package size of the porous electrode or separator decreases the limiting cycles.Under the same unit volume scenario,improving the separator size proportion can accurately control the temperature rise at small current values.Under the same material,volume,and density approximations,the temperature rises slowly for stacked-type supercapacitors as compared to rolled-type supercapacitors.This phenomenon is more pronounced with an increase in current. | Yansong Li Sihan Wang Meina Zheng Jun Liu | 2018 | CSEE Journal of Power and Energy Systems2018，4，1： | 2 |
