6A Sand Control and Development Model in Sandy Land Based on Mixed Experiments of Arsenic Sandstone and Sand: A Case Study in Mu Us Sandy Land in China显示文摘Serious desertification caused by human activity and climate change,in addition to water loss and soil erosion related to arsenic sandstone in the Mu Us Sandy Land,lead to severe scarcity of soil and water resources,which causes worse local agricultural conditions accordingly.Many physical properties of arsenic sandstone is complementary with that of sand,arsenic sandstone is therefore supposed to be blended to enhance water productivity and arability of sandy land.Container experiments are carried out to study the enhancement of water holding capacity of the mixture,the blending ratio of arsenic sandstone and sand,and the proper size of the arsenic sandstone particles,respectively.The results of the experiments show that particle size of 4 cm with a ratio of 1∶2 between arsenic sandstone and sand are the proper parameters on blending.Both water content and fertility increase after blending.Water use efficiency in the mixture is 2.7 times higher than that in sand by the water release curves from experiments.Therefore,a new sand control and development model,including arsenic sandstone blending with sand,efficient water irrigation management and reasonable farming system,is put forward to control and develop sandy land so that water-saving agriculture could be developed.Demonstration of potato planting about 153.1 ha in area in the Mu Us Sandy Land in China indicates that water consumption is 3018 m3/ha in the whole growth period.It means that about 61%of irrigation water can be saved compared with water use in coarse sand without treatment.Recycle economic mode and positive feedback of sand resource-crop planting-soil resource are constructed,which changes sand into arable soil and make it possible to develop water-saving agriculture on it.The proposed model will be helpful for soil-water resources utilization and management in the Mu Us Sandy Land.WANG Ni XIE Jiancang HAN Jichang 2013Chinese Geographical Science2013,23,6:13
7Interval arithmetic operations for uncertainty analysis with correlated interval variables显示文摘A new interval arithmetic method is proposed to solve interval functions with correlated intervals through which the overestimation problem existing in interval analysis could be significantly alleviated. The correlation between interval parameters is defined by the multidimensional parallelepiped model which is convenient to describe the correlative and independent interval variables in a unified framework. The original interval variables with correlation are transformed into the standard space without correlation,and then the relationship between the original variables and the standard interval variables is obtained. The expressions of four basic interval arithmetic operations, namely addition, subtraction, multiplication, and division, are given in the standard space. Finally, several numerical examples and a two-step bar are used to demonstrate the effectiveness of the proposed method.Chao Jiang Chun-Ming Fu Bing-Yu Ni Xu Han 2016Acta Mechanica Sinica2016,32,4:13
8Inflammatory biomarkers and cerebral small vessel disease:a community-based cohort study显示文摘Background and purpose Although inflammation has been proposed to be a candidate risk factor for cerebral small vessel disease(CSVD),previous findings remain largely inconclusive and vary according to disease status and study designs.The present study aimed to investigate possible associations between inflammatory biomarkers and MRI markers of CSVD.Methods A group of 15 serum inflammatory biomarkers representing a variety of those putatively involved in the inflammatory cascade was grouped and assessed in a cross-sectional study involving 960 stroke-free subjects.The biomarker panel was grouped as follows:systemic inflammation(high-sensitivity C reactive protein(hsCRP),interleukin 6 and tumour necrosis factorα),endothelial-related inflammation(E-selectin,P-selectin,intercellular adhesion molecule 1,vascular cell adhesion molecule 1(VCAM-1),CD40 ligand,lipoprotein-associated phospholipase A2,chitinase-3-like 1 protein and total homocysteine(tHCY))and media-related inflammation(matrix metalloproteinases 2,3 and 9,and osteopontin).The association(s)between different inflammatory groups and white matter hyperintensity(WMH),lacunes,cerebral microbleeds(CMBs),enlarged perivascular space(PVS)and the number of deep medullary veins(DMVs)were investigated.Results High levels of serum endothelial-related inflammatory biomarkers were associated with both increased WMH volume(R^(2)=0.435,p=0.015)and the presence of lacunes(R^(2)=0.254,p=0.027).Backward stepwise elimination of individual inflammatory biomarkers for endothelial-related biomarkers revealed that VCAM-1 was significant for WMH(β=0.063,p=0.005)and tHCY was significant for lacunes(β=0.069,p<0.001).There was no association between any group of inflammatory biomarkers and CMBs or PVS.Systemic inflammatory biomarkers were associated with fewer DMVs(R^(2)=0.032,p=0.006),and backward stepwise elimination of individual systemic-related inflammatory biomarkers revealed that hsCRP(β=−0.162,p=0.007)was significant.Conclusion WMH and lacunes were associated with endothelial-related inflammatory biomarkers,and fewer DMVs were associated with systemic inflammation,thus suggesting different underlying inflammatory processes and mechanisms.Ding-Ding Zhang Yuan Cao Jing-Yu Mu Yi-Ming Liu Feng Gao Fei Han Fei-Fei Zhai Li-Xin Zhou Jun Ni Ming Yao Ming-Li Li Zheng-Yu Jin Shu-Yang Zhang Li-Ying Cui Yong Shen Yi-Cheng Zhu 2022Stroke & Vascular Neurology2022,7,4:11
9Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world.Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong 2022Science China(Life Sciences)2022,65,9:9
10Association between large artery stenosis,cerebral small vessel disease and risk of ischemic stroke显示文摘We aimed to assess the associations of large artery stenosis(LAS)and cerebral small vessel disease(CSVD)with the risk of ischemic stroke and to investigate their respective and combined contributions.In the prospective population-based Shunyi Study,1,082 stroke-free participants aged 55.9±9.1 years were included.Participants were followed for incident stroke throughout the study period(2013-2019).Total small vessel disease score was used to measure CSVD burden.Cervico-cerebral large artery stenosis was evaluated via brain magnetic resonance angiography and carotid ultrasound.We estimated the risk of ischemic stroke in relation to LAS and CSVD with Cox regression models.During a mean follow-up of 4.2 years,34 participants(3.1%)experienced at least one ischemic stroke.Severe LAS(≥50% stenosis versus no stenosis:HR=3.27(95%CI:1.31-8.18))and high CSVD burden(total small vessel disease score 2-4 versus 0 point:HR=12.73(4.83-33.53))were associated with increased stroke risk independently.In multivariate models,CSVD burden(7.72%)explained a larger portion of the variation in stroke risk than severity of LAS(3.49%).Our findings identified that both LAS and CSVD were associated with future ischemic stroke in asymptomatic subjects,while those with high CSVD burden deserve more attention in primary prevention of stroke.Fei Han Ding-Ding Zhang Fei-Fei Zhai Jun Xue Jiang-Tao Zhang Shuang Yan Li-Xin Zhou Jun Ni Ming Yao Meng Yang Ming-Li Li Zheng-Yu Jin Qing Dai Shu-Yang Zhang Li-Ying Cui Yi-Cheng Zhu 2021Science China(Life Sciences)2021,64,9:9
11Advances in ultra-high temperature ceramics,composites,and coatings显示文摘Ultra-high temperature ceramics(UHTCs)are generally referred to the carbides,nitrides,and borides of the transition metals,with the Group IVB compounds(Zr&Hf)and TaC as the main focus.The UHTCs are endowed with ultra-high melting points,excellent mechanical properties,and ablation resistance at elevated temperatures.These unique combinations of properties make them promising materials for extremely environmental structural applications in rocket and hypersonic vehicles,particularly nozzles,leading edges,and engine components,etc.In addition to bulk UHTCs,UHTC coatings and fiber reinforced UHTC composites are extensively developed and applied to avoid the intrinsic brittleness and poor thermal shock resistance of bulk ceramics.Recently,high-entropy UHTCs are developed rapidly and attract a lot of attention as an emerging direction for ultra-high temperature materials.This review presents the state of the art of processing approaches,microstructure design and properties of UHTCs from bulk materials to composites and coatings,as well as the future directions.Dewei NI Yuan CHENG Jiaping ZHANG Ji-Xuan LIU Ji ZOU Bowen CHEN Haoyang WU Hejun LI Shaoming DONG Jiecai HAN Xinghong ZHANG Qiangang FU Guo-Jun ZHANG 2022Journal of Advanced Ceramics2022,11,1:9

13Effects of acute kidney injury on acute pancreatitis patients’ survival rate in intensive care unit: A retrospective study显示文摘BACKGROUND Acute kidney injury(AKI)is one of the most common acute pancreatitis(AP)-associated complications that has a significant effect on AP,but the factors affecting the AP patients’survival rate remains unclear.AIM To assess the influences of AKI on the survival rate in AP patients.METHODS A total of 139 AP patients were included in this retrospective study.Patients were divided into AKI group(n=72)and non-AKI group(n=67)according to the occurrence of AKI.Data were collected from medical records of hospitalized patients.Then,these data were compared between the two groups and further analysis was performed.RESULTS AKI is more likely to occur in male AP patients(P=0.009).AP patients in AKI group exhibited a significantly higher acute physiologic assessment and chronic health evaluation II score,higher Sequential Organ Failure Assessment score,lower Glasgow Coma Scale score,and higher demand for mechanical ventilation,infusion of vasopressors,and renal replacement therapy than AP patients in non-AKI group(P<0.01,P<0.01,P=0.01,P=0.001,P<0.01,P<0.01,respectively).Significant differences were noted in dose of norepinephrine and adrenaline,duration of mechanical ventilation,maximum and mean values of intra-peritoneal pressure(IPP),maximum and mean values of procalcitonin,maximum and mean serum levels of creatinine,minimum platelet count,and length of hospitalization.Among AP patients with AKI,the survival rate of surgical intensive care unit and in-hospital were only 23%and 21%of the corresponding rates in AP patients without AKI,respectively.The factors that influenced the AP patients’survival rate included body mass index(BMI),mean values of IPP,minimum platelet count,and hospital day,of which mean values of IPP showed the greatest impact.CONCLUSION AP patients with AKI had a lower survival rate and worse relevant clinical outcomes than AP patients without AKI,which necessitates further attention to AP patients with AKI in surgical intensive care unit.Ni Shi Guo-Dong Sun Yuan-Yuan Ji Ying Wang Yu-Cheng Zhu Wan-Qiu Xie Na-Na Li Qiu-Yuan Han Zhi-Dong Qi Rui Huang Ming Li Zhen-Yu Yang Jun-Bo Zheng Xing Zhang Qing-Qing Dai Gui-Ying Hou Yan-Song Liu Hong-Liang Wang Yang Gao 2021World Journal of Gastroenterology2021,27,38:8
14The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations.Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao 2022Science China(Physics,Mechanics & Astronomy)2022,65,8:7
15^(18)F-fluorodeoxyglucose PET/CT findings of a solitary primary hepatic lymphoma:A case report显示文摘Primary hepatic lymphoma is extremely rare,and only a few cases have been described on positron emission tomography(PET) or PET/computed tomography(PET/CT) imaging in the English literature.We report a case of a 55-year-old woman who presented with low-grade fever and weight loss of three months.On CT scanning,a mass was identified which appeared to be a hypoattenuating lesion,on ultrasonographic imaging,the mass was hypoechoic,therefore,liver abscess or hepatic metastasis from a gastrointestinal primary was initially suspected.Tumor markers such as alpha-fetoprotein,carcinoembryonic antigen and carbohydrate antigen 19-9 were within normal limits.PET/CT demonstrated a large abnormal ring-like hypermetabolic focus in the right liver lobe.The lesion was resected and the histo-pathological findings were consistent with lymphoma.The patient was discharged two weeks after surgery and did not receive any further treatment.After 25 mo follow-up,she is in good health.18F-fluorodeoxyglucose PET/CT is useful in confirming the diagnosis of primary hepatic lymphoma by demonstrating no other foci with high uptake in other parts of the body.Bo Pan Cun-Shi Wang Jian-Kui Han Lin-Feng Zhan Ming Ni Shi-Cheng Xu 2012World Journal of Gastroenterology2012,18,48:6
16Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2.HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou 2019Science China(Physics,Mechanics & Astronomy)2019,62,3:6
17PhERF2,an ethylene-responsive element binding factor,plays an essential role in waterlogging tolerance of petunia显示文摘Ethylene-responsive element binding factors(ERFs)are involved in regulation of various stress responses in plants,but their biological functions in waterlogging stress are largely unclear.In this study,we identified a petunia(Petunia×hybrida)ERF gene,PhERF2,that was significantly induced by waterlogging in wild-type(WT).To study the regulatory role of PhERF2 in waterlogging responses,transgenic petunia plants with RNAi silencing and overexpression of PhERF2 were generated.Compared with WT plants,PhERF2 silencing compromised the tolerance of petunia seedlings to waterlogging,shown as 96%mortality after 4 days waterlogging and 14 days recovery,while overexpression of PhERF2 improved the survival of seedlings subjected to waterlogging.PhERF2-RNAi lines exhibited earlier and more severe leaf chlorosis and necrosis than WT,whereas plants overexpressing PhERF2 showed promoted growth vigor under waterlogging.Chlorophyll content was dramatically lower in PhERF2-silenced plants than WT or overexpression plants.Typical characteristics of programmed cell death(PCD),DNA condensation,and moon-shaped nuclei were only observed in PhERF2-overexpressing lines but not in PhERF2-RNAi or control lines.Furthermore,transcript abundances of the alcoholic fermentation-related genes ADH1-1,ADH1-2,ADH1-3,PDC1,and PDC2 were reduced in PhERF2-silenced plants,but increased in PhERF2-overexpressing plants following exposure to 12-h waterlogging.In contrast,expression of the lactate fermentation-related gene LDH was up-regulated in PhERF2-silenced plants,but downregulated in its overexpressing plants.Moreover,PhERF2 was observed to directly bind to the ADH1-2 promoter bearing ATCTA motifs.Our results demonstrate that PhERF2 contributes to petunia waterlogging tolerance through modulation of PCD and alcoholic fermentation system.Dongmei Yin Daoyang Sun Zhuqing Han Dian Ni Ayla Norris Cai-Zhong Jiang 2019Horticulture Research2019,6,1:6
18The quality traceability system for prefabricated buildings using blockchain:An integrated framework显示文摘The quality traceability of precast components has largely affected the widespread adoption of prefabricated buildings.Blockchain technology provides an effective solution to change the centralized storage mode of traditional traceability system and its related disadvantages.In this paper,we propose a framework of quality traceability system for precast components based on blockchain technology.The system framework adopts a hybrid blockchain architecture and dual storage mode,defines three types of smart contracts,and creates an interactive and efficient source tracing query method,which could effectively achieve the goals of decentralization,openness,and non-tamperability,as well as efficient traceability.Ziyao ZHANG Zhenmin YUAN Guodong NI Han LIN Yujie LU 2020Frontiers of Engineering Management2020,7,4:5

20Dissecting human embryonic skeletal stem cell ontogeny by single-cell transcriptomic and functional analyses显示文摘Human skeletal stem cells(SSCs)have been discovered in fetal and adult long bones.However,the spatiotemporal ontogeny of human embryonic SSCs during early skeletogenesis remains elusive.Here we map the transcriptional landscape of human limb buds and embryonic long bones at single-cell resolution to address this fundamental question.We found remarkable heterogeneity within human limb bud mesenchyme and epithelium,and aligned them along the proximal-distal and anterior-posterior axes using known marker genes.Osteo-chondrogenic progenitors first appeared in the core limb bud mesenchyme,which give rise to multiple populations of stem/progenitor cells in embryonic long bones undergoing endochondral ossification.Importantly,a perichondrial embryonic skeletal stem/progenitor cell(eSSPC)subset was identified,which could self-renew and generate the osteochondral lineage cells,but not adipocytes or hematopoietic stroma.eSSPCs are marked by the adhesion molecule CADM1 and highly enriched with FOXP1/2 transcriptional network.Interestingly,neural crest-derived cells with similar phenotypic markers and transcriptional networks were also found in the sagittal suture of human embryonic calvaria.Taken together,this study revealed the cellular heterogeneity and lineage hierarchy during human embryonic skeletogenesis,and identified distinct skeletal stem/progenitor cells that orchestrate endochondral and intramembranous ossification.Jian He Jing Yan Jianfang Wang Liangyu Zhao Qian Xin Yang Zeng Yuxi Sun Han Zhang Zhijie Bai Zongcheng Li Yanli Ni Yandong Gong Yunqiao Li Han He Zhilei Bian Yu Lan Chunyu Ma Lihong Bian Heng Zhu Bing Liu Rui Yue 2021Cell Research2021,31,7:5
