| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management. | Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng | 2015 | Chinese Birds2015，，3： | 20 |
| 3 | Human monoclonal antibodies block the binding of SARS-CoV-2 spike protein to angiotensin converting enzyme 2 receptor显示文摘According to the World Health Organization(WHO)newly updated situation report on March 18th,2020,the coronavirus disease 2019(COVID-19)pandemic has confirmed 191,127 cases and claimed 7807 deaths worldwide.1 The etiological agent of COVID-19 has been identified as a novel coronavirus,the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),belonging to Sarbecovirus subgenus(genus Betacoronavirus,family Coronaviridae)and showing 79.6 and 96.2%sequence identity in nucleotide to SARS-CoV and a bat coronavirus(BatCoV RaTG13),respectively.2–4 Like SARS-CoV infection,a substantial fraction of COVID-19 patients exhibits severe respiratory symptoms and has to be hospitalized in intensive care unit.5–8 Although the mortality rate of COVID-19 is significantly lower than that of SARS-CoV infection,SARS-CoV-2 shows much higher human-to-human transmission rate,rapidly leading to a global pandemic declared by WHO on March 11th,2020. | Xiangyu Chen Ren Li Zhiwei Pan Chunfang Qian Yang Yang Renrong You Jing Zhao Pinghuang Liu Leiqiong Gao Zhirong Li Qizhao Huang Lifan Xu Jianfang Tang Qin Tian Wei Yao Li Hu Xiaofeng Yan Xinyuan Zhou Yuzhang Wu Kai Deng Zheng Zhang Zhaohui Qian Yaokai Chen Lilin Ye | 2020 | Cellular & Molecular Immunology2020，17，6： | 17 |
| 4 | PARylation regulates stress granule dynamics, phase separation, and neurotoxicity of disease-related RNA-binding proteins显示文摘Mutations in RNA-binding proteins (RBPs) localized in ribonucleoprotein (RNP) granules, such as hnRNP A1 and TDP-43, promote aberrant protein aggregation, which is a pathological hallmark of various neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Protein posttranslational modifications (PTMs) are known to 佗gulate RNP granules. In this study, we investigate the function of poly(ADP-ribosyl)ation (PARylation), an important PTM involved in DNA damage repair and cell death, in RNP granule-related neurodegeneration. We reveal that PARylation levels are a major regulator of the assembly-disassembly dynamics of RNP granules containing disease-related RBPs, hnRNP A1 and TDP-43. We find that hnRNP A1 can both be PARylated and bind to PARylated proteins or poly(ADP-ribose)(PAR). We further uncover that PARylation of hnRNP A1 at K298 controls its nucleocytoplasmic transport, whereas PAR-binding via the PAR-binding motif (PBM) of hnRNP Al regulates its association with stress granules. Moreover, we reveal that PAR not only dramatically enhances the liquid-liquid phase separation of hnRNP A1, but also promotes the co-phase separation of hnRNP A1 and TDP-43 in vitro and their interaction in vivo. Finally, both genetic and pharmacological inhibition of PARP mitigates hnRNP Al- and TDP-43-mediated neurotoxicity in cell and Drosophila models of ALS. Together, our findings suggest a novel and crucial role for PARylation in regulating the dynamics of RNP granules, and that dysregulation in PARylation and PAR levels may con tribute to ALS disease pathoge nesis by promoting protei n aggregation. | Yongjia Duan Aiying Du Jinge Gu Gang Duan Chen Wang Xinrui Gui Zhiwei Ma Beituo Qian Xue Deng Kai Zhang Le Sun Kuili Tian Yaoyang Zhang Hong Jiang Cong Liu Yanshan Fang | 2019 | Cell Research2019，29，3： | 13 |
| 5 | Estimation of eddy heat transport in the global ocean from Argo data显示文摘The Argo data are used to calculate eddy(turbulence)heat transport(EHT)in the global ocean and analyze its horizontal distribution and vertical structure.We calculate the EHT by averaging all the v′,T′profiles within each 2×2 bin.The velocity and temperature anomalies are obtained by removing their climatological values from the Argo'instantaneous'values respectively.Through the Student’s t-test and an error evaluation,we obtained a total of 87%Argo bins with significant depth-integrated EHTs(D-EHTs).The results reveal a positive-and-negative alternating D-EHT pattern along the western boundary currents(WBC)and Antarctic Circumpolar Current(ACC).The zonally-integrated D-EHT(ZI-EHT)of the global ocean reaches 0.12 PW in the northern WBC band and–0.38 PW in the ACC band respectively.The strong ZI-EHT across the ACC in the global ocean is mainly caused by the southern Indian Ocean.The ZI-EHT in the above two bands accounts for a large portion of the total oceanic heat transport,which may play an important role in regulating the climate.The analysis of vertical structures of the EHT along the 35 N and45 S section reveals that the oscillating EHT pattern can reach deep in the northern WBC regions and the Agulhas Return Current(ARC)region.It also shows that the strong EHT could reach 600 m in the WBC regions and 1 000 m in the ARC region,with the maximum mainly located between 100 and 400 m depth.The results would provide useful information for improving the parameterization scheme in models. | ZHANG Zhiwei ZHONG Yisen TIAN Jiwei YANG Qingxuan ZHAO Wei | 2014 | Acta Oceanologica Sinica2014，33，1： | 10 |
| 6 | Evidence of compliance with and effectiveness of guidelines for noninvasive prenatal testing in China:a retrospective study of 189,809 cases显示文摘In China,the medical guidelines recommend performing noninvasive prenatal testing(NIPT)with caution for pregnant women aged 35 years or older.However,the Mother and Child Health Care Law suggests that all primiparous women whose age is older than 35 years undergo prenatal diagnosis.These two inconsistent suggestions/recommendations have made obstetricians confused about whether to offer NIPT to these older pregnant women.To face this issue and find out the solution we performed a retrospective study of 189,809 NIPT samples collected from 28 provincial-leveled administrative units in China.Of 1,564 women with high-risk pregnancies who underwent NIPT,459(29.3%)did not participate in follow-up.The compound sensitivity and specificity of NIPT for trisomies 21,18 and 13 detection was 99.1%(95%CI,98.0%–99.6%)and 99.9%(95%CI,98.8%–99.9%),respectively.In secundiparous women,NIPT showed high sensitivity and specificity similar to that in primiparous women.The observed risk for trisomies 21 and 18 significantly increased when the maternal age was 39 and older.After the publication of the current NIPT policy,the follow-up rate at our center was 97.9%;however,a large number of women are not in maternal and infant care networks nationwide,and that makes the follow-up rate outside our center relatively low.Our study shows that to balance the prevention of major aneuploidies and the limited resources for prenatal diagnosis,the cut-off age of 35 for invasive prenatal diagnosis might be unnecessary.Although the NIPT guidelines are well written,how to practice it effectively,especially in less industrialized areas,is worth discussing. | Chan Tian Tao Deng Xiuhuang Zhu Chen Gong Yangyu Zhao Yuan Wei Rong Li Xiufeng Xu Miaonan He Zhiwei Zhang Jing Cheng Mol BenWillem Jie Qiao | 2020 | Science China(Life Sciences)2020，63，3： | 10 |
| 7 | Impacts of artificially planted vegetation on the ecological restoration of movable sand dunes in the Mugetan Desert,northeastern Qinghai-Tibet Plateau显示文摘Controlling desertification is an important ecological target for the Qinghai-Tibet Plateau of China,where studies on impacts of vegetation restoration measures on sandy soil improvement are still lacking.The Mugetan Desert in Guinan County,Qinghai Province,northeastern Qinghai-Tibet Plateau is a representative ecological restoration area.The impacts of artificial vegetation on the ecological restoration and its properties are studied by using field investigation and sample testing including contents of the surface layer and the vegetation composition of movable,semi-fixed,and fixed sand dunes.Results demonstrate that the moss crust has formed on the surface of a sand dune which has become fixed after 30 years under the impact of artificial vegetation(i.e.Cathay poplar).Meanwhile,the clay minerals,organic matter,and other soil available nutrients have markedly increased.A correlation has been found between these materials,i.e.,clay minerals and organic matter content increasing with silt and clay increases with reduction in sand content.In addition,soil nutrient were positively correlated with the increase of plant diversity.Under the current meteorological conditions,the artificial vegetation is helpful for the stabilization of sand dune and the ecological restoration in the Mugetan Desert. | Yanfu Li Zhiwei Li Zhaoyin Wang Wenlong Wang Yanhong Jia Shimin Tian | 2017 | International Journal of Sediment Research2017，32，2： | 8 |
| 8 | KIF18B promotes tumor progression in osteosarcoma by activating β-catenin显示文摘Objective:Osteosarcoma is a common primary highly malignant bone tumor.Kinesin family member 18B(K1F18B)has been identified as a potential oncogene involved in the development and metastasis of several cancer types.While KIF18B overexpression in osteosarcoma tissue is clearly detected,its specific function in the disease process remains to be established.Methods:K IF18B expression was assessed in osteosarcoma tissues and cells.We additionally evaluated the effects of KIF18B on proliferation,migration,and invasion of osteosarcoma cells,both in vitro and in vivo.Results:Our results showed overexpression of KIF18B in osteosarcoma tissues and cells.Knockdown of K IF18B induced G1/S phase arrest and significantly inhibited proliferation,migration,and invasion of osteosarcoma cells,both in vitro and in vivo.K IF18B regulated P-catenin expression at the transcriptional level by controlling nuclear aggregation of ATF2 and at the post-transcriptional level by interacting with the adenomatous polyposis coli(APC)tumor suppressor gene in osteosarcoma cells.Conclusions:KIF18B plays a carcinogenic role in osteosarcoma by regulating expression ofβ-catenin transcriptionally via decreasing nuclear aggregation of ATF2 or post-transcriptionally through interactions with APC.Our collective findings support the potential utility of KIF18B as a novel prognostic biomarker for osteosarcoma. | Tian Gao Ling Yu Zhiwei Fang Jiayong Liu Chujie Bai Shu Li Ruifeng Xue Lu Zhang Zhichao Tan Zhengfu Fan | 2020 | Cancer Biology & Medicine2020，17，2： | 7 |
| 9 | Efficacy of vinorelbine combined with low-dose methotrexate for treatment of inoperable desmoid tumor and prognostic factor analysis显示文摘Objective: To assess the efficacy of conservative chemotherapy for inoperable desmoid tumor(DT) and analyze the prognostic factors.Methods:From November 2008 to April 2016,71 patients of inoperable DT were treated with vinorelbine and low-dose methotrexate in the Department of Bone and Soft Tissue Tumors,Peking University Cancer Hospital&Institute,and enrolled in this retrospective study.The chemotherapy duration is one year.The efficacy of chemotherapy and the prognosis were observed.Results:Of the 71 patients,55% were female.Age of onset varied from 1 to 47 years,and the median age was 14years.Only 11(15.5%)cases suffered primary tumor.The distribution of the site of tumors was:31(43.7%)in the trunk,36(50.7%)in the limbs,and 4(5.6%)in the peritoneal and pelvic cavity.The size of tumor(the maximum diameter)differed from 2 to 37 cm with a mean of 9.3 cm.The median follow-up duration was 28(range,6–87)months.Common side effects included:nausea and vomiting,liver injury,bone marrow suppression and oral ulcers.When the chemotherapy finished,1(1.4%)case achieved complete response,24(33.8%)achieved partial response,37(52.1%)achieved stable disease and 9(12.7%)had progressive disease.The overall response rate was 87.3%.The progression-free survival(PFS)of the participants were from 6 to 87 months,and the 2-,3-and 5-year PFS was 79.9%,68.4% and 36.3%,respectively.No significant difference was identified in PFS in subgroups of gender,age of onset,age of chemotherapy,tumor site and tumor size.Conclusions:For recurrent,inoperable and progressive DT,enough course of chemotherapy with vinorelbine combined with low-dose methotrexate was an optional choice for local control. | Shu Li Zhengfu Fan Zhiwei Fang Jiayong Liu Chujie Bai Ruifeng Xue Lu Zhang Tian Gao | 2017 | Chinese Journal of Cancer Research2017，29，5： | 6 |
| 10 | Comparison of nitrate-removal efficiency and bacterial properties using PCL and PHBV polymers as a carbon source to treat aquaculture water显示文摘Nitrate(NO_(3)^(−))accumulation in recirculating aquaculture systems(RASs)with high stocking densities presents a problem for reared animals and the environment.The use of a biodegradable polymer as organic carbon for heterotrophic denitrification exhibits good performance for NO_(3)^(−)removal from wastewater.A comparison of NO_(3)^(−)–N removal efficiency and bacterial properties using polycaprolactone(PCL)and poly(3-hydroxybutyrateco-3-hydroxyvalerate)(PHBV)as carbon sources to treat aquaculture water was conducted for a 102-day period.The results indicated that the NO_(3)^(−)–N removal rates of 0.27±0.07 and 0.19±0.05 g/L per day,respectively,could be achieved with influent concentrations ranging from 81.1 to 132.75 mg/L and a flow rate of 1 L/h.The removal of NO_(3)^(−)–N versus consumed PCL(1:1 w/w)was significantly higher than that versus consumed PHBV(0.3:1 w/w)(P<0.05).The concentrations of effluent nitrite-nitrogen and total ammonium nitrogen were maintained at an acceptable level.The bacterial community structures between the two types of reactors varied significantly.Acidovorax and Denitratisoma were the top two genera of the bacterial community in the biofilm in the PCL beads with a dominance of 26.83%and 6.67%,respectively.In the PHBV beads,Acidovorax at 17.95%and Bdellovibrio at 6.37%were the top two genera.The PCL-denitrification reactor developed in this study showed better potential than the PHBV-denitrification reactor in removing NO_(3)^(−)from aquaculture water. | Guozhi Luo Zhiwei Hou Luqi Tian Hongxin Tan | 2020 | Aquaculture and Fisheries2020，5，2： | 5 |
| 11 | The histone methyltransferase EZH2 primes the early differentiation of follicular helper T cells during acute viral infection显示文摘Epigenetic modifications to histones dictate the differentiation of naïve CD4^(+) T cells into different subsets of effector T helper(TH)cells.The histone methyltransferase enhancer of zeste homolog 2(EZH2)has been implicated in the mechanism regulating the differentiation of TH1,TH2 and regulatory T(Treg)cells.However,whether and how EZH2 regulates follicular helper T(TFH)cell differentiation remain unknown.Using a mouse model of acute lymphocytic choriomeningitis virus(LCMV)infection,we observed abundant EZH2 expression and associated H3K27me3 modifications preferentially in the early committed virus-specific TFH cells compared to those in TH1 cells.Ablation of EZH2 in LCMV-specific CD4^(+) T cells leads to a selective impairment of early TFH cell fate commitment,but not late TFH differentiation or memory TFH maintenance.Mechanistically,EZH2 specifically stabilizes the chromatin accessibility of a cluster of genes that are important for TFH fate commitment,particularly B cell lymphoma 6(Bcl6),and thus directs TFH cell commitment.Therefore,we identified the chromatin-modifying enzyme EZH2 as a novel regulator of early TFH differentiation during acute viral infection. | Xiangyu Chen Guoshuai Cao Jialin Wu Xinxin Wang Zhiwei Pan Jianbao Gao Qin Tian Lifan Xu Zhirong Li Yaxing Hao Qizhao Huang Pengcheng Wang Minglu Xiao Luoyingzi Xie Shupei Tang Zhenyu Liu Li Hu Jianfang Tang Ran He Li Wang Xinyuan Zhou Yuzhang Wu Mengjie Chen Beicheng Sun Bo Zhu Jun Huang Lilin Ye | 2020 | Cellular & Molecular Immunology2020，17，3： | 4 |
| 12 | Hydrothermal Synthesis of Ce-doped ZnO Heterojunction Supported on Carbon Nanofibers with High Visible Light Photocatalytic Activity显示文摘Ce/ZnO decorated carbon nanofibers(CNFs)heteroarchitectures(Ce/ZnO/CNFs)have been synthesized using electrospinning technique followed hydrothermal method,which have a high visible light photocatalytic activity.The samples were characterized by means of SEM,FTIR and XRD.The photocatalytic performance of Ce/ZnO/CNFs was tested with the methylene blue in the presence of visible light irradiation.In this work,we have analyzed the effects of Ce doping amount,initial methylene blue(MB)concentration and dosage of Ce/ZnO/CNFs on photocatalytic efficiency of the composite.The results showed that the photocatalyst containing 1.0%Ce in molarity(CZC1)obtained by autoclaving at 150℃ has the best photocatalytic degradation of MB than other as-synthesized samples.Ce/ZnO/CNFs catalysts exhibit a good stability and reusability,which would be an economical and environmentally friendly photocatalyst for various practical applications. | JIAN Shaoju TIAN Zhiwei ZHANG Kaiyin DUAN Gaigai YANG Weisen JIANG Shaohua | 2021 | Chemical Research in Chinese Universities2021，37，3： | 4 |
| 13 | Fast integration and accumulation of beneficial breeding alleles through an AB–NAMIC strategy in wheat显示文摘Wheat(Triticum aestivum)is among the most important staple crops for safeguarding the food security of the growing world population.To bridge the gap between genebank diversity and breeding programs,we developed an advanced backcross-nested association mapping plus inter-crossed population(AB-NAMIC)by crossing three popular wheat cultivars as recurrent founders to 20 germplasm lines from a mini core collection.Selective backcrossing combined with selection against undesirable traits and extensive crossing within and between sub-populations created new opportunities to detect unknown genes and increase the frequency of beneficial alleles in the AB-NAMIC population.We performed phenotyping of 590 AB-NAMIC lines and a natural panel of 476 cultivars for six consecutive growing seasons and genotyped these 1066 lines with a 660K SNP array.Genome-wide association studies of both panels for plant development and yield traits demonstrated improved power to detect rare alleles and loci with medium genetic effects in AB-NAMIC.Notably,genome-wide association studies in AB-NAMIC detected the candidate gene TaSWEET6-7B(TraesCS7B03G1216700),which has high homology to the rice SWEET6b gene and exerts strong effects on adaptation and yield traits.The commercial release of two derived AB-NAMIC lines attests to its direct applicability in wheat improvement.Valuable information on genome-wide association studymapping,candidate genes,and their haplotypes for breeding traits are available through WheatGAB.Our research provides an excellent framework for fast-tracking exploration and accumulation of beneficial alleles stored in genebanks. | Chengzhi Jiao Chenyang Hao Tian Li Abhishek Bohra Lanfen Wang Jian Hou Hongxia Liu Hong Liu Jing Zhao Yamei Wang Yunchuan Liu Zhiwei Wang Xin Jing Xiue Wang Rajeev K.Varshney Junjie Fu Xueyong Zhang | 2023 | Plant Communications2023，4，3： | 3 |
| 14 | Mineral composition and particle size distribution of river sediment and loess in the middle and lower Yellow River显示文摘Hyperconcentrated flows often occur in the middle and lower Yellow River(MLYR)and its tributaries,within which the main sediment source originates from the Loess Plateau of China due to serious water erosion.Little is known about the properties of river sediment that is transported by hyperconcentrated flows,particularly with respect to the mineral composition and size distribution.Samples of sediment and loess were collected in the northern,middle,and southern Loess Plateau and the mainstream and tributaries of the MLYR.A total of 18 loess samples and 24 river sediment samples were analyzed to determine their sediment size distribution and mineral composition.The bottom loess samples reflected the original sedimentary features of the Loess Plateau,and the median particle size reduced,and the clay content increased from the north to the south of the study region.The surface loess has been weathered under the action of wind and rainfall,and the clay particle content in the surface loess samples was higher than that in the undisturbed bottom loess.Erosion of the surface soil due to rainfall and surface runoff means that fine particles(mostly clay)have been washed away.The median diameter of surface loess particles was a little larger than that of the bottom loess particles where water erosion dominates.The particle size became coarser with increasing distance from the estuary in the MLYR,which reflects depositional sorting in the river channel.Significant logarithmic relations were found between the median diameter of the sediment particles and the i)non-clay mineral content and ii)clay mineral content.Thus,clay and non-clay mineral compositions can be conveniently estimated from the particle size distribution. | Shimin Tian Zhiwei Li Zhaoyin Wang Enhui Jiang Wenlong Wang Meng Sun | 2021 | International Journal of Sediment Research2021，36，3： | 3 |

| 16 | Genomic footprints of wheat evolution in China reflected by a Wheat660K SNP array显示文摘Common wheat(Triticum aestiuum L.)is one of the most important crops because it provides about 20%of the total calories for humans.T.aestiuum is an excellent modern species for studying concerted evolution of sub-genomes in polyploid species,because of its large chromosome size and three well-known genome donors.Establishment of common wheat genome reference sequence and development of high-density SNP chips provide an excellent foundation to answer questions of wheat evolution and breeding at the genomic level.By genotyping more than 600 accessions of common wheat and their diploid and tetraploid ancestors using a Wheat660 K SNP array,we found dramatic genome changes due to tetraploidization and hexaploidization,in contrast to weaker influences of domestication and breeding on them.Further,since common wheat was introduced in China in 1500 BCE,Chinese landraces formed two subgroups(T.aestiuum-L1 and T.aestiuum-L2)with considerably diverse geographic distributions and agronomic traits.T.aestiuum-L2,mainly distributed in central and east China is found to have more but smaller oval grains with early maturity characteristics.We found that variation and selection in intergenic regions of the A and B sub-genomes dominated this differentiation,in which chromosomes 7 A and 3 B took the leading roles due to the existence of putative genes related to defense responses and environmental adaption in the highly differentiated regions.Large haplotype blocks were detected on 3 B(232.6-398.3 Mb)and 7 A(211.7-272.9 Mb)in the landraces,forming two distinct haplotypes,respectively.We discovered that artificial crosses in breeding promoted recombination in the whole genome,however,this recombination and differentiation was highly asymmetric among the three sub-genomes in homoeologous regions.In addition,we found that the wide use of European and northern American cultivars in breeding at early era,led dramatic changes in Chinese wheat genome,whereas,the recent breeding functioned to optimize it.This study will provide the insight for reconsideration of wheat evolution and breeding,and a new strategy for parent selection in breeding. | Zhiwei Wang Chenyang Hao Jing Zhao Chang Li Chengzhi Jiao Wei Xi Jian Hou Tian Li Hongxia Liu Xueyong Zhang | 2021 | The Crop Journal2021，9，1： | 2 |
| 17 | Application status and challenges of machine vision in plant factory—A review显示文摘Plant factories have a great potential for mitigating the contradiction between the world’sgrowing population and food scarcity. During the process of its automatic production,machine vision plays a significant role. This technique almost covers every production linkfrom raising seedlings, transplanting, management, and harvesting to fruit grading. To provide references and a starting point for those who are committed to studying this issue. Inthis paper, the application prospects of machine vision in plant factories were analyzed,and the present researches were summarized from the fields of plant growth monitoring,robot operation assistance, and fruit grading. The results found that although the existingmethods have solved some practical problems at low cost, high efficiency and precision,some challenges still are faced by machine vision. Firstly, the changing lighting, complexbackgrounds, and color similarity within plant different parts cause the commonly usedimage segmentation algorithms to fail. The shortage of standard agricultural datasets alsokeeps deep learning and unsupervised classification algorithms from making progress.Secondly, there are some theoretical knowledge gaps for machine vision application in aparticular environment of plant factories, which seriously contains its application effect.Thirdly, the lack of special image acquisition devices and supporting facilities resulted inpoor image quality. All these factors hinder machine vision application in plant factories.Nevertheless, it is still a powerful tool and irreplaceable at present. We believed that thistechnique would promote plant factory development greatly with more robust, efficient,and reliable algorithms are developed in the future. | Zhiwei Tian Wei Ma Qichang Yang Famin Duan | 2022 | Information Processing in Agriculture2022，9，2： | 2 |

| 20 | Large-area hydrated vanadium oxide/carbon nanotube composite films for high-performance aqueous zinc-ion batteries显示文摘Synchronously reducing/self-assembling strategy on Zn substrate was designed to fabricate large-area cation-doped hydrated V_(2)O_(5)/multi-walled carbon nanotube(D-HVO/MWCNT)composite films.Interestingly,the Zn^(2+)ions are simultaneously doped in hydrated V_(2)O_(5) during the assembly process,which will be beneficial to the high electrochemical performance of hydrated V_(2)O_(5).By further combining 3D conductive MWCNT network,the freestanding D-HVO/MWCNT composite films display high capacity,excellent rate capability,and remarkable long-term cycling performance(up to 10,000 cycles with a high capacity retention of 98.5%).Moreover,owing to the high conductivity and flexibility of the D-HVO/MWCNT composite films,the softpackaged aqueous zinc-ion batteries(ZIBs)were constructed based on such composite films.The devices exhibit stable electrochemical performance even under different bending states.Therefore,such a strategy provides a promising route to achieve large-area carbon and metal oxides-based composite films with high performance and good flexibility. | Hongmei Cao Shenzhen Deng Zhiwei Tie Jinlei Tian Lili Liu Zhiqiang Niu | 2022 | Science China Chemistry2022，65，9： | 1 |
