| 1 | Geological Characteristics and Ore-forming Time of the Dexing Porphyry Copper Ore Mine in Jiangxi Province显示文摘The Dexing porphyry copper ore mine is located in the Qin-Hang metallogenic belt between the Yangtze block and the Cathaysia block. It is a giant porphyry copper mine in China, including 3 ore districts: Tongchang, Fujiawu and Zhushahong. Our analyses of Re in molybdenite indicate that the ore-forming material of the copper ore deposits in Dexing should be mainly mantle-derived. Our study fills in a gap in the study of formation time of the Dexing copper mine, and further proves that the copper ore deposits in the three ore districts should be formed simultaneously, about 170 Ma, belonging to the early Yanshan period, and that the formation time of the copper ore deposits should be consistent with the formation time of granodiorite porphyry in which the copper ore deposits are hosted. Promising areas for seeking porphyry copper ore deposits is predicated to be the west or southwest of Dexing. | GUO Shuo ZHAO Yuany QU Huanchun WU Dexin XU Hong LI Chao LIU Yan ZHU Xiaoyun WANG Zengke | 2012 | Acta Geologica Sinica(English Edition)2012，86，3： | 28 |
| 2 | Seasonal patterns and environmental control of ecosystem respiration in subtropical and temperate forests in China显示文摘Continuous measurement of carbon dioxide exchange using the eddy covariance (EC) technique was made at two ChinaFLUX forest sites including the young subtropical Pinus plantation (Qianyanzhou) and old temperate broad-leaved Korean pine mixed forest (Changbai Mountains) as part of the ChinaFLUX network. Seasonal patterns and environmental control of ecosystem respiration in the subtropical and temperate forests were evaluated by the often-used multiplicative model and Q10 model as a function of temperature and soil water content. The resuits suggested that ( i ) temperature was found to be a dominant factor in the ecosystem respiration, and most of the temporal variability of ecosystem respiration was explained by temperature. However, in the drought-stressed ecosystem, soil water content controlled the temporal variability of ecosystem respiration other than temperature effects, and soil water content became a dominat factor when severe drought affected the ecosystem respiration; (ii) the regression models analysis revealed that in the drier soil, ecosystem respiration was more sensitive to soil moisture than was expressed by the often-used multiplicative model. It was possible to accurately estimate the seasonal variation of ecosystem respiration based on the Q10 model; and (iii)annual ecosystem respiration derived from the often-used multiplicative model was 1209 g C m-2and 1303 g C m-2, and was consistently a little higher than the Q10 model estimates of 1197 g C m-2 and 1268 g C m-2 for Qianyanzhou and Changbai Mountains, respectively. | YU Guirui, WEN Xuefa, LI Qingkang, ZHANG Leiming, REN Chuanyou, LIU Yunfen & GUAN Dexin Chinese Ecosystem Research Network Synthesis Research Center, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Institute of Applied Ecology, Chinese Academy of Sciences, Shenyang 110016, China Graduate School of the Chinese Academy of Sciences, Beijing 100039, China | 2005 | Science China Earth Sciences2005，48，z1： | 13 |
| 3 | Validity and reliability of Chinese version of Fatigue Impact Scale in cerebral infarction patients显示文摘BACKGROUND: Post-stroke fatigue has received much attention recently. Three evaluation scales are available,including the Fatigue Impact Scale (FIS). Yet none of these has been proven to be of use in the evaluation of psychological quality after post-stroke fatigue. OBJECTIVE: To introduce FIS into China,and to evaluate the validity and reliability of the Chinese Version in patients with cerebral infarction. DESIGN: Scale evaluation. SETTING: Department of Rehabilitation,Beijing Friendship Hospital,Capital Medical University. PARTICIPANTS: A total of 330 patients with cerebral infarction were selected from the Department of Neurology,Beijing Friendship Hospital,Capital Medical University from June 2005 to December 2006. All patients met diagnostic standards from the Fourth National Cerebrovascular Disease Academic Meeting of China Medical Association and were diagnosed with CT or MRI examination. Patients who were not willing to accept scale evaluation were excluded. METHODS: The English version of FIS was translated into Chinese and subsequently translated back to English again. FIS was given to the discharged patients,and they returned them upon completion. In-patients completed and immediately returned the FIS. Validity and reliability of the retrieved scales were ascertained with descriptive and inference analysis. MAIN OUTCOME MEASURES: Total scores and subscale scores of FIS. RESULTS: Out of 330 questionnaires,214 valid questionnaires were deemed valid in total. Six components were extracted in factor analysis,and the total cumulative contribution was 73.919%,which suggested the questionnaire was valid. After correlation analysis,6 components were divided into 3 subscales,including cognitive,physical,and social,which was the same as the English version. The Cronbach α value for the three subscales was 0.937 7,0.918 8,and 0.940 6,respectively (> 0.7). CONCLUSION: The reliability and validity of the Chinese version of FIS met with satisfaction and ap-peared to be adaptable to cerebral infarction patients in China. | Chunwei Wu Zhandong Liu Yongbo Zhang Jimei Li Dexin Wang | 2008 | Neural Regeneration Research2008，3，2： | 6 |

| 5 | Triassic Granitic Magmatism at the Northern Margin of the North China Craton: Implications of Geochronology and Geochemistry for the Tectonic Evolution of the Central Asian Orogenic Belt显示文摘The early Mesozoic marked an important transition from collisional orogeny to post-orogenic extension at the northern margin of the North China Craton(NCC). In this study, we undertook zircon U-Pb dating and whole-rock majorand trace-element geochemical analyses of early Mesozoic granitic rocks in the Chifeng area to establish their geochronological framework, petrogenesis, and implications for the tectonic evolution of the eastern Central Asia Orogenic Belt(CAOB). Zircon U-Pb dating results show that these rocks were emplaced in three stages during the Triassic:(1) syenogranites during 250-248 Ma,(2) granodiorites during 244-243 Ma, and(3) monzogranites and granodiorites during 232-230 Ma. These Triassic granitoids belong to the high-K calc-alkaline series and are evolved I-type granites. They have high SiO2 and low Mg O contents with enrichments in light rare-earth elements, Zr, Hf, Rb, Th, and U, and depletions in Ba, Nb, Ta, Sr, and Eu. These geochemical data indicate that the granitoids were derived from partial melting of a lower-crustal source under relatively low-pressure conditions and subsequently underwent extensive fractional crystallization. Considering both the geochemical data and regional geological information, we propose that the 250-248 Ma syenogranites were emplaced in an extensional environment linked to slab break-off after closure of the Paleo-Asian Ocean(PAO) along the Solonker-Xra Moron-Changchun suture zone. The 244-243 Ma granodiorites were formed in a compressional orogenic setting during collision between the Erguna-Xing’an-Songliao composite block and the NCC. The 232-230 Ma granodiorites and monzogranites were emplaced during the transition from compressional orogeny to post-orogenic extension. Overall, the early Mesozoic tectonic evolution of the Chifeng area can be divided into three main stages:(1) closure of the Paleo-Asian Ocean and extension related to slab break-off during the Early Triassic;(2) continuous collisional compression during the Middle Triassic after closure of the PAO;and(3) post-orogenic extension during the Late Triassic, most probably due to lithospheric delamination after amalgamation of the Erguna-Xing’an-Songliao composite block and the NCC. | CHEN Jingsheng TIAN Dexin YANG Hao LI Weiwei LIU Miao LI Bin YANG Fan LI Wei WU Zhen | 2019 | Acta Geologica Sinica(English Edition)2019，93，5： | 4 |
| 6 | Effects of temperature and light on seed germination of ephemeral plants in the Gurbantunggut Desert, China: implications for vegetation restoration显示文摘Seed germination is a key transitional stage in plant life cycle and is strongly regulated by temperature and light.Therefore, research on the effects of temperature and light on seed germination is extremely meaningful for vegetation restoration, especially in desert ecosystems.Seeds of 28 ephemeral plants collected from the Gurbantunggut Desert of China were incubated at different temperatures(5℃/1℃, 15℃/5℃, 20℃/5℃, 25℃/10℃ and 30℃/15℃) in 12-h light/12-h darkness or continuous darkness regimes, and the responses of seed germination to temperature and light and the germination speed were studied in 2016.Results showed that seed germination percentage of the 28 ephemeral plants significantly differed to temperature and light.We classified the studied plants as the following groups based on their responses to temperature: 1 low temperature responsed plants, 12 moderate temperature responsed plants, 7 high temperature responsed plants, 4 non-responsed plants and 5 plants of no germination.It should be noted that Corispermum lehmannianum Bunge is sensitive to both moderate and high temperatures.There were 4 groups of plant in response to light, i.e., 7 light responsed plants, 10 dark responsed plants, 6 light non-responsed plants and 5 plants of no germination.Based on seed germination speed of the 28 ephemeral plants, we divided them into 4 patterns of germination, i.e., very rapid, moderately rapid, moderate and slow.Combining variations of temperature, precipitation and sand dune types in the study area, we suggested that very rapid and moderately rapid germinated plants could be used to moving sand dunes in early spring during vegetation restoration, moderate germinated plants could be used to semi-fixed sand dunes in late autumn, and slow germinated plants could be used to sand plain in summer.Thus, seedling establishment and vegetation restoration would be improved by considering seed germination characteristics of these ephemeral plants in the Gurbantunggut Desert, China. | CHEN Yanfeng CAO Qiumei LI Dexin LIU Huiliang ZHANG Daoyuan | 2019 | Journal of Arid Land2019，11，6： | 4 |
| 7 | Molecular evolution and genetic diversity analysis of SFTS virus based on next-generation sequencing显示文摘SFTS virus(SFTSV)is a novel bunyavirus,which was discovered as the etiological agent of severe fever with thrombocytopenia syndrome(SFTS)in China in 2009,and was now prevalent in at least 25 provinces in China.SFTS was subsequently identified in South Korea and Japan in 2012.To explore themolecular evolution and genetic characteristics of this newly identified pathogen,we reported 72 whole genome sequences of SFTSV,and built a dataset of SFTSV genome sequences containing 292 L-segment,302 M-segment and 502 S-segment.We clearly divided SFTSV into six genotypes,Genotype A-F.It was found that genotype F was the dominant epidemic genotype of Japan,South Korea,and Zhejiang province of China.The coalescent analysis supported that SFTSV originated in the early 18th century from Zhejiang province,and Genotype F was the most primitive one.Henan,Hubei,and Anhui provinces which are located in Dabie Mountain area weremainly epidemic of Genotype A,which emerged relatively late but distributed widely.A total of 37 recombination events were identified,making SFTSV with a high recombination frequency(L segment 5.1%,Msegment 3.6%,S segment 0.8%)among negative-strand segmented RNA viruses.It was identified that 19 reassortant strains belonged to 12 reassortment forms of SFTSV genome containing 6 newly identified forms.The reassortment virus and recombination in tick were both found for the first time.We also found many of genotype-specific mutation sites,7 of which could be considered as potential molecular marker for genotype classification.This study promoted a more comprehensive understanding of the phylogeny and origin,and the genetic diversity of SFTSV,and it could help the studies of other newly discovered tick-borne bunyavirus as reference data and research ideas. | Aqian Li Lin Liu Wei Wu Yang Liu Xiaoxia Huang Chuan Li Di Liu Jiandong Li Shiwen Wang Dexin Li Mifang Liang | 2021 | Biosafety and Health2021，3，2： | 4 |
| 8 | SNX11 Identified as an Essential Host Factor for SFTS Virus Infection by CRISPR Knockout Screening显示文摘Severe fever with thrombocytopenia syndrome virus(SFTSV)is a highly pathogenic tick-borne bunyavirus that causes lethal infectious disease and severe fever with thrombocytopenia syndrome(SFTS)in humans.The molecular mechanisms and host cellular factors required for SFTSV infection remain uncharacterized.Using a genome-wide CRISPR-based screening strategy,we identified a host cellular protein,sorting nexin 11(SNX11)which is involved in the intracellular endosomal trafficking pathway,as an essential cell factor for SFTSV infection.An SNX11-KO HeLa cell line was established,and SFTSV replication was significantly reduced.The glycoproteins of SFTSV were detected and remained in later endosomal compartments but were not detectable in the endoplasmic reticulum(ER)or Golgi apparatus.pH values in the endosomal compartments of the SNX11-KO cells increased compared with the pH of normal HeLa cells,and lysosomal-associated membrane protein 1(LAMP1)expression was significantly elevated in the SNX11-KO cells.Overall,these results indicated that penetration of SFTSV from the endolysosomes into the cytoplasm of host cells was blocked in the cells lacking SNX11.Our study for the first time provides insight into the important role of the SNX11 as an essential host factor in the intracellular trafficking and penetrating process of SFTSV infection via potential regulation of viral protein sorting,membrane fusion,and other endocytic machinery. | Tiezhu Liu Jiajia Li Yang Liu Yuanyuan Qu Aqian Li Chuan Li Quanfu Zhang Wei Wu Jiandong Li Yan Liu Dexin Li Shiwen Wang Mifang Liang | 2019 | Virologica Sinica2019，34，5： | 3 |
| 9 | Antibody Cocktail Exhibits Broad Neutralization Activity Against SARS-CoV-2 and SARS-CoV-2 Variants显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)has precipitated multiple variants resistant to therapeutic antibodies.In this study,12 high-affinity antibodies were generated from convalescent donors in early outbreaks using immune antibody phage display libraries.Of them,two RBD-binding antibodies(F61 and H121)showed high-affinity neutralization against SARS-Co V-2,whereas three S2-target antibodies failed to neutralize SARS-Co V-2.Following structure analysis,F61 identified a linear epitope located in residues G446–S494,which overlapped with angiotensinconverting enzyme 2(ACE2)binding sites,while H121 recognized a conformational epitope located on the side face of RBD,outside from ACE2 binding domain.Hence the cocktail of the two antibodies achieved better performance of neutralization to SARS-Co V-2.Importantly,these two antibodies also showed efficient neutralizing activities to the variants including B.1.1.7 and B.1.351,and reacted with mutations of N501 Y,E484 K,and L452 R,indicated that it may also neutralize the recent India endemic strain B.1.617.The unchanged binding activity of F61 and H121 to RBD with multiple mutations revealed a broad neutralizing activity against variants,which mitigated the risk of viral escape.Our findings revealed the therapeutic basis of cocktail antibodies against constantly emerging SARS-Co V-2 variants and provided promising candidate antibodies to clinical treatment of COVID-19 patients infected with broad SARS-Co V-2 variants. | Yuanyuan Qu Xueyan Zhang Meiyu Wang Lina Sun Yongzhong Jiang Cheng Li Wei Wu Zhen Chen Qiangling Yin Xiaolin Jiang Yang Liu Chuan Li Jiandong Li Tianlei Ying Dexin Li Faxian Zhan Youchun Wang Wuxiang Guan Shiwen Wang Mifang Liang | 2021 | Virologica Sinica2021，36，5： | 3 |

| 11 | Hundred-Joule-level,nanosecond-pulse Nd:glass laser system with high spatiotemporal beam quality显示文摘A 100-J-level Nd:glass laser system in nanosecond-scale pulse width has been constructed to perform as a standard source of high-fluence-laser science experiments. The laser system, operating with typical pulse durations of 3–5 ns and beam diameter 60 mm, employs a sequence of successive rod amplifiers to achieve 100-J-level energy at 1053 nm at3 ns. The frequency conversion can provide energy of 50-J level at 351 nm. In addition to the high stability of the energy output, the most valuable of the laser system is the high spatiotemporal beam quality of the output, which contains the uniform square pulse waveform, the uniform flat-top spatial fluence distribution and the uniform flat-top wavefront. | Sensen Li Yulei Wang Zhiwei Lu Lei Ding Yi Chen Pengyuan Du Dexin Ba Zhenxing Zheng Xin Wang Hang Yuan Chengyu Zhu Weiming He Dianyang Lin Yongkang Dong Dengwang Zhou Zhenxu Bai Zhaohong Liu Can Cui | 2016 | High Power Laser Science and Engineering2016，4，1： | 3 |

| 13 | Serological Investigation of Laboratory-Confirmed and Suspected Ebola Virus Disease Patients During the Late Phase of the Ebola Outbreak in Sierra Leone显示文摘This study aimed to investigate the serological characteristics of Ebola virus(EBOV) infection during the late phase of the Ebola outbreak in Sierra Leone. In total, 877 blood samples from 694 suspected Ebola virus disease(EVD) cases assessed from March to December 2015, were analyzed via real-time reverse transcription polymerase chain reaction(RT-PCR) for viral RNA and enzyme-linked immunosorbent assay(ELISA) and Luminex to detect antibodies against EBOV. Viral load and EBOV-specific IgM/IgG titers displayed a declining trend during March to December 2015. Viral RNA load decreased rapidly at earlier stages after disease onset, while EBOV-specific IgM and IgG still persisted in 58.1%(18/31) and 93.5%(29/31) of the confirmed EVD patients and in 3.8%(25/663) and 17.8%(118/663) of the RNA-negative suspected patients in the later phase, respectively. Dynamic analysis of longitudinally collected samples from eight EVD patients revealed typically reversed trends of declining viral load and increasing IgM and/or IgG titers in response to the EBOV infection.The present results indicate that certain populations of Sierra Leone developed immunity to an EBOV infection in the late phase of the outbreak, providing novel insights into the risk assessment of EBOV infections among human populations. | Yang Liu YuLan Sun Wei Wu AQian Li XianDa Yang Shuo Zhang Chuan Li QiuDong Su ShaoJian Cai DaPeng Sun HaiYang Hu Zhe Zhang XiuXu Yang Idrissa Kamara Sheku Koroma Gerald Bangura Alie Tia Abdul Kamara Matt Lebby Brima Kargbo Jiandong Li Shiwen Wang XiaoPing Dong YueLong Shu WenBo Xu George F.

| 14 | Random seismic noise attenuation by learning-type overcomplete dictionary based on K-singular value decomposition algorithm显示文摘The transformation of basic functions is one of the most commonly used techniques for seismic denoising,which employs sparse representation of seismic data in the transform domain. The choice of transform base functions has an influence on denoising results. We propose a learning-type overcomplete dictionary based on the K-singular value decomposition( K-SVD) algorithm. To construct the dictionary and use it for random seismic noise attenuation,we replace fixed transform base functions with an overcomplete redundancy function library. Owing to the adaptability to data characteristics,the learning-type dictionary describes essential data characteristics much better than conventional denoising methods. The sparsest representation of signals is obtained by the learning and training of seismic data. By comparing the same seismic data obtained using the learning-type overcomplete dictionary based on K-SVD and the data obtained using other denoising methods,we find that the learning-type overcomplete dictionary based on the K-SVD algorithm represents the seismic data more sparsely,effectively suppressing the random noise and improving the signal-to-noise ratio. | XU Dexin HAN Liguo LIU Dongyu WEI Yajie | 2016 | Global Geology2016，19，1： | 2 |
| 15 | Fluorouracil-based preoperative chemoradiotherapy with or without oxaliplatin for stage Ⅱ/Ⅲ rectal cancer:a 3-year follow-up study显示文摘Background:Fluorouracil-based preoperative chemoradiotherapy has become the standard treatment for stage II/III rectal cancer.In order to improve the overall survival(OS) and disease-free survival(DFS),we added oxaliplatin to the standard treatment,and compared the effectiveness of these two treatment patterns.Methods:A total of 206 patients enrolled in the prospective study had histologically confirmed rectal cancer of clinical stage II/III during July 2007 to July 2010.They were randomized into the experimental group received oxaliplatin and capecitabine in combination with radiotherapy,and the control group received capecitabine in combination with radiotherapy.All patients received surgery in 6-10 weeks after chemoradiotherapy and adjuvant chemotherapy with m FOLFOX6.The primary endpoints were DFS and OS,and the secondary endpoints included toxicity,compliance,and histopathological response.Results:The 3-year OS in the experimental group and the control group was 90.29% vs.86.41%(P>0.05),and the 3-year DFS was 80.58% vs.69.90%(P>0.05).The pathological complete remission(p CR) rates were 23.30% and 19.42%,respectively(P=0.497).The 3-year local recurrence rates were 4.85% vs.5.83%(P=0.694),and the 3-year distant metastasis rates were 16.50% and 28.16%,respectively(P=0.045).There were no significant differences in most grade 3-4 toxicities between two groups,however,grade 3-4 diarrhea occurred in 16.50%(17/103) of the experimental group,compared with 6.80%(7/103) of the control group(P=0.030).Also,the total grade 3-4 acute toxicity showed a significant difference(10.68% vs.21.36%,P=0.037).Conclusions:The experimental treatment did not lead significantly improved OS and DFS,and thus longer follow-up is warranted for our patient cohort.Adding oxaliplatin to capecitabine-based preoperative chemoradiotherapy can significantly reduce metastasis,but has only minimal impact on local recurrence.Although grade 3-4 toxicity rate increased(primarily gastrointestinal toxicity),patients can stand to be followed up with allopathic treatment. | Dexin Jiao Rui Zhang Zhiqiang Gong Fang Liu Yue Chen Qinrui Yu Liping Sun Hongyan Duan Shendong Zhu Fei Liu Jian Wang Jianhui Jia | 2015 | Chinese Journal of Cancer Research2015，27，6： | 2 |
| 16 | Study on the Physiological,Cellular,and Morphological Aspects of the Postharvest Development of Cut Lily Flowers显示文摘It is of great practical significance to study the development process of cut lily for regulating flowering and preservation.In this study,the developmental process of lily cut flower was explored from cellular,morphological,and physiological aspects.Froma morphological aspect,the tepal edge grows faster than the midrib.The midrib groove of the flowering stage is wider than that of bud stage.The fast-growing edge of the petals results in the midrib bending outward.Moreover,the rapid growth of the stamens and stigmas also contributes to bud cracking.From the cellular aspect,in the bud stage there were more wrinkles in the outer epidermal cell wall of the tepal than those in the inner epidermal cell wall,indicating that asymmetric structural differences exist from the beginning of lily development.From a physiological aspect,from the bud cracking stage to the senescence stage,a variety of substances in the tepal cells gradually decreased,including total nitrogen,total phosphorus,total potassium,total calcium,starch,soluble sugar,and soluble protein,but not malondialdehyde.These results indicate that the asymmetric growth caused by this structural difference is responsible for flowering.The wrinkles in the cell wall can be regarded as indicators of senescent cells and are caused by the degradation of the cell wall and the loss of intracellular turgor pressure.The differences in the epidermal cells between the inner and outer tepal indicated ultrastructural changes in the tepal cells.The bud and flowering stages are maintained by the tepals acting as a sink.After flowering,the tepals gradually change from a sink to a source organ.Senescence of the cut lily flowers was caused by the decomposition of intracellular compounds in the tepals and the remobilization of nutrients from the tepals to the developing organs. | Yushan Zhang Dexin Zhong Zhanfei Liu Jiawei Gao | 2021 | Horticultural Plant Journal2021，7，2： | 2 |

| 19 | Comparison of finite difference and pseudo-spectral methods in forward modelling based on metal ore model of random media显示文摘With more applications of seismic exploration in metal ore exploration,forward modelling of seismic wave has become more important in metal ore. Finite difference method and pseudo-spectral method are two important methods of wave-field simulation. Results of previous studies show that both methods have distinct advantages and disadvantages: Finite difference method has high precision but its dispersion is serious; pseudospectral method considers both computational efficiency and precision but has less precision than finite-difference. The authors consider the complex structural characteristics of the metal ore,furthermore add random media in order to simulate the complex effects produced by metal ore for wave field. First,the study introduced the theories of random media and two forward modelling methods. Second,it compared the simulation results of two methods on fault model. Then the authors established a complex metal ore model,added random media and compared computational efficiency and precision. As a result,it is found that finite difference method is better than pseudo-spectral method in precision and boundary treatment,but the computational efficiency of pseudospectral method is slightly higher than the finite difference method. | LIU Dongyu HAN Liguo ZHANG Pan XU Dexin | 2016 | Global Geology2016，19，2： | 1 |
