1Spatiotemporal variations of nitrate sources and dynamics in a typical agricultural riverine system under monsoon climate显示文摘Nitrogen pollution is a serious environmental issue in the Danjiangkou Reservoir region(DRR),the water source of the South-to-North Water Diversion Project of China.In this research,seasonal surveys and a bi-weekly time series survey were conducted in the Qihe River Basin,one of the most densely populated agricultural basins in the DRR.Hydrochemical compositions(NO3^-Cl^-),dual isotopes(δD-H2O,δ^18O-H2O,δ^15N-NO3^-,andδ^18O-NO3^-),and a Markov Chain Monte Carlo isotope mixing model were jointly applied to unravel the sources,migrations,and transformations of the nitrate(NO3^-)in the basin.It was revealed that the mixing between different sources was the main process controlling the isotopic compositions of the riverine NO3the upper-middle reaches.In contrast,denitrification occurred in the lower reaches.For the first time,the sources of NO3^-quantified at a basin scale in the DRR.Overall,the river transported 484.2 tons/year of NO3^-N to the reservoir,of which 32.6%,36.4%,28.0%,and 3.0%was from soil organic nitrogen,chemical fertilizer,residential sewage and atmospheric precipitation,respectively.The NO3^-N fluxes of the different sources were regulated by the monsoon climate and anthropogenic activities.For example,high precipitation and intense fertilization resulted in severe nonpoint source pollution.Denitrification thrived in soils and reservoirs in wet seasons.Temperature could regulate the migration,nitrification and denitrification processes.Based on the results,we suggest that the management strategies dealing with nitrogen pollution issue in the DRR should follow the specific spatiotemporal characteristics of NO3migration and transformation mechanisms.Hao Jiang Wenjing Liu Jiangyi Zhang Li Zhou Xiaode Zhou Ke Pan Tong Zhao Yuchen Wang Zhifang Xu 2020Journal of Environmental Sciences2020,32,7:5

3X16老年人平衡能力测试量表的信度和效度评估(摘译)显示文摘近几十年来,老龄化已成为当今社会的重要公共卫生问题之一。全世界几乎所有国家中60岁及以上的人口数都在逐步、迅速地增长。2012年,全球老年人口占总人口的11%以上。据联合国人口基金会估计,到2050年这一比例将达到约22%。2012年,我国有1.8亿老年人,截至2015年,65岁及以上老人占全国总人口的10.5%,预计到2050年该比例还会增长近三分之一。上海是我国人口最多也是平均期望寿命最高的城市,2014年老年人口比例达到28.8%。随着年龄的增长,老年人的生理、认知和行动能力均有不同程度下降,因此,有必要对老龄化进程中的特点进行研究。姜玉(摘译) 夏庆华(审校) Jingjuan Ju Peng Zhou Lin Li Xiaolei Ye Hongmei Wu Bin Shen Jialei Zhang Xiaoding He Chunjin Niu 2021伤害医学(电子版)2021,10,1:1
4Red AIE conjugated polyelectrolytes for long-term tracing and image-guided photodynamic therapy of tumors显示文摘Robust photosensitizers with strong red/NIR fluorescence, efficient reactive oxygen species(ROS) generation and high photostability are highly desired for photodynamic therapy(PDT). Herein, three novel red conjugated polyelectrolytes(CPEs) with tetraphenylethene and 2,1,3-benzothiadiazole on the main chains and triphenylphosphonium on the side chains are developed.These CPEs display apparent aggregation-induced emission feature and high fluorescence quantum yields in the aggregated state. They can target lysosome in He La cells for fluorescence bioimaging. By virtue of the good retention effect and high photostability, these CPEs show ultralong-term tracing performance of subcutaneous tumors, and the tumor site can still be visualized for 20 days after injection. Owing to their good biocompatibility and strong ROS generation ability, the image-guided PDT based on these CPEs can effectively inhibit the growth of subcutaneous tumor and significantly prolong the survival of tumor bearing mice. The H&E and IHC staining reveal that the PDT of these CPEs depress the proliferation of tumor cells, and promote apoptosis and necrosis process. These new CPEs may be employed both as fluorescent probes for in vitro and in vivo long-term tracing and as photosensitizers for image-guided PDT of tumors.Hongming Yao Jun Dai Zeyan Zhuang Jinya Yao Zixuan Wu Shixuan Wang Fan Xia Jian Zhou Xiaoding Lou Zujin Zhao 2020Science China Chemistry2020,63,12:1
5A Study on Dual-Load-Zone Model of Overlying Strata andEvolution Law of Mining Stress显示文摘The changeable structure and movement law of overlying strata are the maincontributor to the change of mining stress.Starting from the relevant theory of keystratum and particularly based on the theory of mine ground pressure and strata control,this research proposed a new solution to mining stress problems by establishing adual-load-zone stratum structural model.Elastic foundation beam theory was used tosolve the stress of overlying strata of the dual-load-zones with superposition method,which revised the traditional calculation method of mining stress.The abnormal increaseof lead abutment pressure in the mining area was explained effectively,through which theevolution law of mining stress in the case of hard rock was obtained.The results indicatethat mining stress experiences a drastic change within the range of 50 m ahead of the coalwall due to the collapse of main roof;under the influence of main key stratum andinferior key strata,the influence range of lead abutment pressure is extended up toapproximately 120 m in the working face;this remarkable increase can be attributed tothe excessive length of sagging zone.Results from both the dual-load-zone modelexperiment and field measurement demonstrate high consistency.The model can predictthe influence range of abutment pressure effectively and thus guide the safety productionof mining.Yuejin Zhou Mingpeng Li Xiaoding Xu Meng Li 2019Computers, Materials & Continua2019,,2:1
6Current situation and development of facial prosthesis显示文摘Facial prostheses have developed significantly in the last 10 years,especially between 2016 and 2021.This development is mainly due to the great progress made in the fields of biocompatible materials,digital technology,and three-dimensional printing technology,which provides guarantee for low allergy,high biosimulation,comfort,and satisfactory usability.Treatment teams typically consist of plastic surgeons,material experts,engineers,and computer scientists who have extensive clinical experience.These teams successfully implement an integrated,multidisciplinary model by prioritizing the reasonable expectations of both the physician and patient,leading to improved patient satisfaction and compliance with prosthetic constraints.This study aimed to review the concept,development status,existing problems,and future of facial prosthesis.Xin Li Jia Xu Jiajun Fan Yaxin Xue Xiaoding Gu Hengxing Zhou Dong Han 2023Chinese Journal Of Plastic and Reconstructive Surgery2023,5,1:0
7Genomic insights on the contribution of introgressions from Xian/Indica to the genetic improvement of Geng/Japonica rice cultivars显示文摘Hybridization between Xian/indica(XI)and Geng/japonica(GJ)rice combined with utilization of plant ideotypes has greatly contributed to yield improvements in modern GJ rice in China over the past 50 years.To explore the genomic basis of improved yield and disease resistance in GJ rice,we conducted a large-scale genomic landscape analysis of 816 elite GJ cultivars representing multiple eras of germplasm from China.We detected consistently increasing introgressions from three XI subpopulations into GJ cultivars since the 1980s and found that the XI genome introgressions significantly increased the grain number per panicle(GN)and decreased the panicle number per plant.This contributed to the improvement of plant type during modern breeding,changing multi-tiller plants tomoderate tiller plants with a large panicle size and increasing the blast resistance.Notably,we found that key gene haplotypes controlling plant architecture,yield components,and pest and disease resistance,including IPA1,SMG1,DEP3,Pib,Pi-d2,and Bph3,were introduced from XI rice by introgression.By GWAS analysis,we detected a GN-related gene Gnd5,which had been consistently introgressed from XI into GJ cultivars since the 1980s.Gnd5 is a GRAS transcription factor gene,and Gnd5 knockout mutants showed a significant reduction in GN.The estimated genetic effects of genes varied among different breeding locations,which explained the distinct introgression levels of XI gene haplotypes,including Gnd5,DEP3,etc.,to these GJ breeding pedigrees.These findings reveal the genomic contributions of introgressions from XI to the trait improvements of GJ rice cultivars and provide new insights for future rice genomic breeding.Di Cui Han Zhou Xiaoding Ma Zechuan Lin Linhua Sun Bing Han Maomao Li Jianchang Sun Jin Liu Guixiu Jin Xianju Wang Guilan Cao Xing Wang Deng Hang He Longzhi Han 2022Plant Communications2022,3,3:0
