| 1 | On the timing of the East Asian summer monsoon maximum during the Holocene Does the speleothem oxygen isotope record reflect monsoon rainfall variability?显示文摘The evolution of the East Asian summer monsoon(EASM) during the Holocene has long been of significant interest.Knowledge of past EASM variability not only increases our understanding of monsoon dynamics on a long timescale,but it also provides an environmental and climatic background for research into Chinese cultural development.However,the timing of the EASM maximum remains controversial.The popular concept of an 'early Holocene maximum' is mainly based on speleothemδ^(18)O(δ^(18)O_c) records from caves in southern China;however,the interpretation of δ^(18)O_C as a reliable proxy for EASM intensity is being increasingly challenged.The present paper is a critical review of the climatic significance of the δ^(18)O_C record from China.Firstly,we suggest that precipitation in northern China is an appropriate index of EASM intensity,the variation of which clearly indicates a mid-Holocene monsoon maximum.Secondly,an interregional comparison demonstrates that the precipitation record in northern China is quite different from that in southern China on a range of timescales,and is inconsistent with the spatial similarity exhibited by speleothem oxygen isotope records.Furthermore,both modeling and observational data show that the δ^(18)O_C records from southern China indeed reflect changes in precipitation δ^(18)O(δ^(18)O_P) rather than precipitation amount,and therefore that their use as an EASM proxy is inappropriate.Finally,we address several significant monsoon-related issues-including the driving mechanism of the EASM on an orbital timescale,the climatic significance of speleothem oxygen isotopes,and the relationship between atmospheric circulation and precipitation in monsoonal regions. | CHEN JianHui RAO ZhiGuo LIU JianBao HUANG Wei FENG Song DONG GuangHui HU Yu XU QingHai CHEN FaHu | 2016 | Science China(Information Sciences)2016，59，12： | 18 |
| 2 | 恶性肿瘤骨转移及骨相关疾病临床诊疗中国专家共识(英文)显示文摘Since 1980s, palliative medicine has been an independent educational project. The development of palliative care in China started in the early 1990s. During the last 18 years, we have seen an increasing allocation of resources to palliative care, the establishment of an academic chair in palliative medicine, and more focused interest and awareness of the need for palliative care in the society at large. So the doctors in China have established principles of treatment on clinical diagnosis and treatment of malignant tumor bone metastases and bone related complications. In order to share our experience with the world, after two years’ preparation, the top-level experts in palliative medicine have written the consensus statement on clinical diagnosis and treatment of malignant tumor bone metastases and bone related complications. The overview includes not only the achievements in the world, but the hands-on experience in clinic, especially the experience in combination of TCM and Western medicine. We hope that the publication of this consensus statement will contribute to the palliative medicine development in this field, thus bring benefits to the majority of patients. | Shiying Yu Zefei Jiang Li Zhang Xiaohui Niu Lvhua Wang Ning Wu Jianhui Ma | 2010 | The Chinese-German Journal of Clinical Oncology2010，9，1： | 15 |
| 3 | Major advances in studies of the physical geography and living environment of China during the past 70 years and future prospects显示文摘The natural environment provides material essentials for human survival and development. The characteristics,processes, regional differentiation and forcing mechanisms of the elements of the natural environment(e.g. geomorphology,climate, hydrology, soil, etc.) are the main objects of research in physical geography. China has a complex natural environment and huge regional differentiation and therefore it provides outstanding reserach opportunities in physical geography. This review summarizes the most important developments and the main contributions of research in the physical geography and human living environment in China during the past 70 years. The major topics addressed are the uplift of the Tibetan Plateau and the evolution of its cryosphere, the development of fluvial systems, the acidification of the vast arid region of the Asian interior, variations in the monsoon and westerly climate systems on multiple timescales, the development of lakes and wetlands, the watershed system model, soil erosion, past human-environment interactions, biogeography, and physical geographic zonality. After briefly introducing international research developments, we review the history of research in physical geography in China, focusing on the major achievements and major academic debates, and finally we summarize the status of current research and the future prospects. We propose that in the context of the national demand for the construction of an ecological civilization, we should make full use of the research findings of physical geography, and determine the patterns and mechanisms of natural environmental processes in order to continue to promote the continued contribution of physical geography to national development strategies, and to further contribute to the theory of physical geography from a global perspective. | Fahu CHEN Bojie FU Jun XIA Duo WU Shaohong WU Yili ZHANG Hang SUN Yu LIU Xiaomin FANG Boqiang QIN Xin LI Tingjun ZHANG Baoyuan LIU Zhibao DONG Shugui HOU Lide TIAN Baiqing XU Guanghui DONG Jingyun ZHENG Wei YANG Xin WANG Zaijun LI Fei Wang Zhenbo HU Jie WANG Jianbao LIU Jianhui CHEN Wei HUANG Juzhi HOU Qiufang CAI Hao LONG Ming JIANG Yaxian HU Xiaoming FENG Xingguo MO Xiaoyan YANG Dongju ZHANG Xiuhong WANG Yunhe YIN Xiaochen LIU | 2019 | Science China Earth Sciences2019，62，11： | 11 |

| 6 | Sensitivity-enhanced surface plasmon resonance sensor utilizing a tungsten disulfide (WS_2) nanosheets overlayer显示文摘Tungsten disulfide(WS_2), as a representative layered transition metal dichalcogenide(TMDC) material, possesses important potential for applications in highly sensitive sensors. Here, a sensitivity-enhanced surface plasmon resonance(SPR) sensor with a metal film modified by an overlayer of WS_2 nanosheets is proposed and demonstrated. The SPR sensitivity is related to the thickness of the WS_2 overlayer, which can be tailored by coating a WS_2 ethanol suspension with different concentrations or by the number of times of repeated post-coating.Benefitting from its large surface area, high refractive index, and unique optoelectronic properties, the WS_2 nanosheet overlayer coated on the gold film significantly improves the sensing sensitivity. The highest sensitivity(up to 2459.3 nm∕RIU) in the experiment is achieved by coating the WS_2 suspension once. Compared to the case without a WS_2 overlayer, this result shows a sensitivity enhancement of 26.6%. The influence of the WS_2 nanosheet overlayer on the sensing performance improvement is analyzed and discussed. Moreover, the proposed WS_2 SPR sensor has a linear correlation coefficient of 99.76% in refractive index range of 1.333 to 1.360. Besides sensitivity enhancement, the WS_2 nanosheet overlayer is able to show additional advantages, such as protection of metal film from oxidation, tunability of the resonance wavelength region, biocompatibility, capability of vapor,and gas sensing. | HAO WANG HUI ZHANG JIANGLI DONG SHIQI HU WENGUO ZHU WENTAO QIU HUIHUI LU JIANHUI YU HEYUAN GUAN SHECHENG GAO ZHAOHUI LI WEIPING LIU MIAO HE JUN ZHANG ZHE CHEN YUNHAN LUO | 2018 | Photonics Research2018，6，6： | 8 |
| 7 | Effect of Bushenhuoxue formula on interleukin-1 beta and discoidin domain receptor 2 levels in a rat model of osteoarthritis显示文摘OBJECTIVE:To determine the effects of Bushenhuoxue formula(BHF) on interleukin-1 beta(IL-1β),transforming growth factor beta 1(TGF-β1),discoidin domain receptor 2(DDR2) and matrix metalloproteinase-1(MMP-1) levels in a rat model of osteoarthritis(OA).METHODS:Sprague-Dawley rats were used to establish an OA model and subjected to various treatments over 6 weeks.Rats were treated with BHF,glucosamine sulfate(G5),or starch as a control.Serum levels of IL-1β and MMP-1 and joint fluid levels of IL-1 β were determined by means of ELISAs.We used immunohistochemistry to determine DDR2 levels in knee cartilage.Gene expression levels of MMP-1 in joint synovial tissue were assessed using reverse transcription polymerase chain reaction assays.RESULTS:Serum IL-1β levels were unchanged throughout the study.Levels of IL-1β in joint fluid and MMP-1 in sera from the BHF- and GS-treated groups were significantly reduced.DDR2 levels in knee cartilage were also significantly reduced in the BHF group.Expression of the MMP-1 gene was significantly reduced by BHF treatment.CONCLUSION:BHF might be beneficial in the inhibition and alleviation of local inflammatory responses and cartilage degeneration in OA. | Li Nianhu Xia Lei Yi Sheng Yu Jianhui Zhai Yi Xu Zhanwang | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 7 |
| 8 | Industrial Spatial Agglomeration Using Distance-based Approach in Beijing, China显示文摘To study the difference of industrial location among different industries, this article is to test the spatial agglomeration across industries and firm sizes at the city level. Our research bases on a unique plant-level data set of Beijing and employs a distance-based approach, which considers space as continuous. Unlike previous studies, we set two sets of references for service and manufacturing industries respectively to adapt to the investigation in the intra-urban area. Comparing among eight types of industries and different firm sizes, we find that: 1) producer service, high-tech industries and labor-intensive manufacturing industries are more likely to cluster, whereas personal service and capital-intensive industries tend to be randomly dispersed in Beijing; 2) the spillover of the co-location of firms is more important to knowledge-intensive industries and has more significant impact on their allocation than business-oriented services in the intra-urban area; 3) the spatial agglomeration of service industries are driven by larger establishments, whereas manufacturing industries are mixed. | LI Jiaming ZHANG Wenzhong YU Jianhui CHEN Hongxia | 2015 | Chinese Geographical Science2015，25，6： | 7 |
| 9 | 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 |
| 10 | Spatial and temporal variation in magnetic properties of street dust in Lanzhou City,China显示文摘Urban environmental problems are of increasing concern. Lanzhou is a large industrial city in North-west China. Street dust samples representing different temporal and spatial scales were collected for magnetic properties study. Magnetic measurements indicate a high concentration of magnetic minerals in Lanzhou street dust, dominated by pseudo-single domain (PSD) magnetite. The concentration of magnetic materials is distinctly high in winter and spring, low in autumn. Similarly, higher concentra-tions associated with heavy industry, concentrated residential development, and vehicular traffic sug-gest mixed contributions of magnetic material from both anthropogenic and natural sources. χ_lf and SOFT% are effective magnetic parameters that denote seasonal differences among magnetic proper-ties in street dust, convenient and economical methods for monitoring street dust pollution. | WANG Guan XIA DunSheng LIU XiuMing CHEN FaHu YU Ye YANG LiPing CHEN JianHui ZHOU AiFeng | 2008 | Chinese Science Bulletin2008，53，12： | 7 |

| 12 | Association of a missense mutation in the luteinizing hormone/choriogonadotropin receptor gene (LHCGR) with superovulation traits in Chinese Holstein heifers显示文摘Background: Upon binding luteinizing hormone in the ovary, the luteinizing hormone/choriogonadotropin receptor (LHCGR) is necessary for follicular maturation and ovulation, as well as luteal function. We detected mutations in the LHCGR gene and evaluated their association with superovulation. Methods: Using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and DNA sequencing, we examined polymorphisms in LHCGR and the genotypes associated with superovulation traits in 127 Chinese Holstein heifers. Results: A G/T polymorphism (ss52050737) in exon 11 was significantly associated with the total number of ova and the number of transferable embryos. Conclusions: LHCGR may be a new predictor for superovulation in Chinese Holstein heifers. | Yong Yu Yunwei Pang Haichao Zhao Xiaoling Xu Zhonghong Wu Lei An Jianhui Tian | 2012 | Journal of Animal Science and Biotechnology2012，3，4： | 6 |

| 14 | Haplotype variations in QTL for salt tolerance in Chinese wheat accessions identified by marker-based and pedigree-based kinship analyses显示文摘Most modern wheat cultivars were selected on the basis of yield-related indices measured under optimal fertilizer and irrigation inputs.With climate change,land degradation and salinity caused by sea water encroachment,wheat is increasingly subjected to environmental stress.Moreover,expanding urbanization increasingly encroaches upon prime agricultural land in countries like China,and alternative cropping areas must be found.Some of these areas have moderate constraining factors,such as salinity.Therefore,it is important to investigate whether current genetic materials and breeding procedures are maintaining adequate variability to address future problems caused by abiotic stress.In this study,a panel of 307 wheat accessions,including local landraces,exotic cultivars used in Chinese breeding programs and Chinese cultivars released during different periods since1940,were subjected to a genome-wide association study to dissect the genetic basis of salinity tolerance.Both marker-based and pedigree-based kinship analyses revealed that favorable haplotypes were introduced in some exotic cultivars as well as a limited number of Chinese landraces from the 1940 s.However,improvements in salinity tolerance during modern breeding are not as obvious as that of yield.To broaden genetic diversity for increasing salt tolerance,there is a need to refocus attention on local landraces that have high degrees of salinity tolerance and carry rare favorable alleles that have not been exploited in breeding. | Shizhou Yu Jianhui Wu Meng Wang Weiming Shi Guangmin Xia Jizeng Jia Zhensheng Kang Dejun Han | 2020 | The Crop Journal2020，8，6： | 4 |
| 15 | Homogeneous label-free fluorescent assay of small molecule-protein interactions using protein binding-inhibited transcription nanomachine显示文摘Quantitative analysis of interactions between small molecules and proteins is a central challenge in chemical genetics, molecular diagnostics and drug developments. Here, we developed a RNA transcription nanomachine by assembling T7 RNA polymerase on a small molecule-labeled DNA heteroduplex. The nanomachine, of which the RNA transcription activity can be quantitatively inhibited by protein binding, showed a great potential for small molecule-protein interaction assay. This finding enabled us to develop a novel homogeneous label-free strategy for assays of interactions between small molecules and their protein receptors. Three small molecule compounds and their protein receptors have been used to demonstrate the developed strategy. The results revealed that the protein-small molecule interaction assay strategy shows dynamic responses in the concentration range from 0.5 to 64 nM with a detection limit of 0.2 nM. Due to its label-free, homogeneous, and fluorescence-based detection format, besides its desirable sensitivity this technique could be greatly robust, cost-efficient and readily automated, implying that the developed small molecule-protein interaction assay strategy might create a new methodology for developing intrinsically robust, sensitive and selective platforms for homogeneous protein detection. | ZHOU DianMing, WU YiDan, LIU Pei, BAI HaoTian, TANG LiJuan, YU RuQin & JIANG JianHui State Key Laboratory of Chemo/Bio-Sensing and Chemometrics College of Chemistry and Chemical Engineering, Hunan University, Changsha 410082, China | 2011 | Science China Chemistry2011，54，8： | 4 |
| 16 | Photonic cavity enhanced high-performance surface plasmon resonance biosensor显示文摘Herein we propose a novel strategy to enhance surface plasmon resonance(SPR)by introducing a photonic cavity into a total-internal-reflection architecture.The photonic cavity,which is comprised of a highly reflective photonic crystal(PC),defect layers,and a gold(Au)film,enables Fabry–Perot(FP)resonances in the defect layers and therefore narrows the SPR resonance width in the metallic surface as well as increases the electric field intensity and penetration depth in the evanescent region.The fabricated sensor exhibits a 5.7-fold increase in the figure of merit and a higher linear coefficient as compared with the conventional Au-SPR sensor.The demonstrated PC/FP cavity/metal structure presents a new design philosophy for SPR performance enhancement. | GUI-SHI LIU XIN XIONG SHIQI HU WEICHENG SHI YAOFEI CHEN WENGUO ZHU HUADAN ZHENG JIANHUI YU NUR HIDAYAH AZEMAN YUNHAN LUO ZHE CHEN | 2020 | Photonics Research2020，8，4： | 4 |
| 17 | Generation and characterization of stable pig pregastrulation epiblast stem cell lines显示文摘Pig epiblast-derived pluripotent stem cells are considered to have great potential and broad prospects for human therapeutic model developme nt and livestock breeding.Despite on going attempts since the 1990s,no stably defined pig epiblast-derived stem cell line has bee n established.Here,guided by in sights from a large-scale sin gle-cell tran scriptome an alysis of pig embryos from embryonic day(E)0 to E14,specifically,the tracing of pluripotency changes during epiblast development,we developed an in vitro culture medium for establishing and maintaining stable pluripotent stem cell lines from pig E10 pregastrulation epiblasts(pgEpiSCs).Enabled by chemical inhibition of WNT-related signaling in combination with growth factors in the FGF/ERK,JAK/STAT3,and Activin/Nodal pathways,pgEpiSCs maintain their pluripotency transcriptome features,similar to those of E10 epiblast cells,and normal karyotypes after more than 240 passages and have the potential to differentiate into three germ layers.Strikingly,ultradeep in situ Hi-C analysis revealed functional impacts of chromatin 3D-spatial associations on the transcriptional regulation of pluripote ncy marker genes in pgEpiSCs.I n practice,we con firmed that pgEpiSCs readily tolerate at least three rounds of successive gene editi ng and gene rated cloned gen e-edited live piglets.Our findings deliver on the long-a nticipated promise of pig pluripote nt stem cells and open new avenues for biological research,animal husbandry,and regenerative biomedicine. | Minglei Zhi Jinying Zhang Qianzi Tang Dawei Yu Shuai Gao Dengfeng Gao Pengliang Liu Jianxiong Guo Tang Hai Jie Gao Suying Cao Zimo Zhao Chongyang Li Xiaogang Weng Mengnan He Tianzhi Chen Yingjie Wang Keren Long Deling Jiao Guanglei Li Jiaman Zhang Yan Liu Yu Lin Daxin Pang Qianqian Zhu Naixin Chen Jingjing Huang Xinze Chen Yixuan Yao Jingcang Yang Zicong Xie Xianya Huang Mengxin Liu Ran Zhang Qiuyan Li Yiliang Miao Jianhui Tian Xingxu Huang Hongsheng Ouyang Bofeng Liu Wei Xie Qi Zhou Zhonghua Liu Caihong Zheng Mingzhou Li Jianyong Han | 2022 | Cell Research2022，32，4： | 3 |

| 19 | The temporal and spatial evaluation on China's agricultural policy output since 1978显示文摘Since reform and opening up, how much contribution has China's implementation of new agricultural policy made to agricultural output? This paper is trying to establish an agricultural policy output econometric model for doing a quantitative analysis of China's new agricultural policy. The results show that China's agricultural policies on agricultural output have an average contribution rate of about 7% since 1978, which is consistent with the OECD's basic forecast. There are obvious temporal and spatial differences. Generally speaking, we can divide the contribution of agricultural policy into three periods, which are the start-up phase from 1978 to 1991 (14 years), the stationary phase from 1992 to 2002 (11 years) and the rising phase from 2003 to 2008 (6 years). In space, the contribution of agricultural policy underwent a process from the all-low in the start-up phase, the gradual increase in the stationary phase to the all-high in the rising phase. Northern and western regions are more sensitive to policies. There are three major factors that can affect the contribution of regional agricultural policies, which are the process of national industrialization strategy, terrain and the level of local finance. | YU Jianhui | 2011 | Journal of Geographical Sciences2011，21，3： | 3 |
