| 1 | Establishing eutrophication assessment standards for four lake regions, China显示文摘The trophic status assessment of lakes in diferent lake regions may provide important and fundamental information for lake trophic state classification and eutrophication control. In this study, a region-specific lake eutrophication assessment standard was established through a frequency distribution method based on chlorophyll-a concentration. The assessment standards under the oligotrophic state for lakes in the Eastern plain, Yungui Plateau, Northeast Plain and Mountain Mongolia-Xinjiang regions are total phosphorus of 0.068,0.005, 0.011, 0.005 mg/L; total nitrogen of 1.00, 0.16, 0.37, 0.60 mg/L; Secchi depth of 0.60, 8.00, 1.55, 3.00 m; and CODMn of2.24, 1.00, 5.11, 4.00 mg/L, respectively. Moreover, a region-specific comprehensive trophic level index was developed to provide an understandable assessment method for the public. The results indicated that the frequency distribution analysis based on chlorophyll-a combined with trophic level index provided a useful metric for the assessment of the lake trophic status. In addition, the diference of eutrophication assessment standards in diferent lake regions was analyzed, which suggested that the sensitivities of algae to nutrients and the assessment standard of trophic status possessed significant regional diferences for the four lake ecoregions. Lake eutrophication assessment standards would contribute to maximizing the efectiveness of future management strategies, to control and minimize lake eutrophication problems. | Shouliang Huo Chunzi Ma Beidou Xi Jing Su Fengyu Zan Danfeng Ji Zhuoshi He | 2013 | Journal of Environmental Sciences2013,25,10: | 18 |
| 2 | Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers. | Rui Chen Shancheng Ren 无 Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun | 2014 | Asian Journal of Urology2014,1,1: | 13 |
| 3 | Percent free prostate-specific antigen for prostate cancer diagnosis in Chinese men with a PSA of 4.0-10.0 ng/mL:Results from the Chinese Prostate Cancer Consortium显示文摘Objective:To test the diagnostic performance of percent free prostate-specific antigen(%fPSA)in predicting any prostate cancer(PCa)and high-grade prostate cancer(HGPCa)in a retrospective multi-center biopsy cohort with a PSA level of 4.0e10.0 ng/mL in China.Methods:Consecutive patients with a PSA of 4.0-10.0 ng/mL who underwent transrectal ultrasound-guided biopsy were enrolled at 16 Chinese medical centers from January 1st,2010 to December 31st,2013.Total and free serum PSA determinations were performed using three types of electro-chemiluminescence immunoassays recalibrated to the World Health Organization(WHO)standard.The diagnostic accuracy of PSA,%fPSA,and %fPSA in combination with PSA(%fPSA t PSA)was determined using the area under the receiver operating characteristic(ROC)curve(AUC).Results:A total of 2310 consecutive men with PSA levels between 4.0 and 10.0 ng/mL were included,and the detection rate of PCa was 25.1%.The AUC of%fPSA and %fPSA t PSA in predicting any PCa was superior to PSA alone in men aged≥60 years(0.623 vs.0.534,p<0.0001)but not in men aged 40e59 years(0.517 vs.0.518,p=0.939).Similar result was yield in predicting HGPCa.Conclusion:In a clinical setting of Chinese men with 4.0e10.0 ng/mL PSA undergoing initial prostate biopsy,adding %fPSA to PSA can moderately improve the diagnostic accuracy for any PCa and HGPCa compared with PSA alone in patients≥60 but not in patients aged 40-59 years. | Rui Chen Liping Xie Xiaobing Cai Yiran Huang Liqun Zhou Lulin Ma Xu Gao Chuanliang Xu Shancheng Ren Pengfei Shao Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Li Lu Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tie Zhou Fubo Wang Biming He Yinghao Sun | 2015 | Asian Journal of Urology2015,2,2: | 8 |
| 4 | High-Resolution Genome-wide Association Study Identifies Genomic Regions and Candidate Genes for Important Agronomic Traits in Wheat显示文摘Wheat(Triticum aestivum)is a major staple food crop worldwide.Genetic dissection of important agronomic traits is essential for continuous improvement of wheat yield to meet the demand of the world's growing population.We conducted a large-scale genome-wide association study(GWAS)using a panel of 768 wheat cultivars that were genotyped with 327609 single-nucleotide polymorphisms generated by genotyping-by-sequencing and detected 395 quantitative trait loci(QTLs)for 12 traits under 7 environments.Among them,273 QTLs were delimited to≤1.0-Mb intervals and 7 of them are either known genes(Rht-D,Vrn-B1,and Vrn-D1)that have been cloned or known QTLs(TaGA2ox8,APO1,TaSus1-7B,and Rht12)that were previously mapped.Eight putative candidate genes were identified for three QTLs that enhance spike seed setting and grain size using gene expression data and were validated in three bi-parental populations.Protein sequence analysis identified 33 putative wheat orthologs that have high identity with rice genes in QTLs affecting similar traits.Large r^2 values for additive effects observed among the QTLs for most traits indicated that the phenotypes of these identified QTLs were highly predictable.Results from this study demonstrated that significantly increasing GWAS population size and marker density greatly improves detection and identification of candidate genes underlying a QTL,solidifying the foundation for large-scale QTL fine mapping,candidate gene validation,and developing functional markers for genomics-based breeding in wheat. | Yunlong Pang Chunxia Liu Danfeng Wang Paul St.Amand Amy Bernardo Wenhui Li Fang He Linzhi Li Liming Wang Xiufang Yuan Lei Dong Yu Su Huirui Zhang Meng Zhao Yunlong Liangi Hongze Jia Xitong Shen Yue Lu Hongming Jiang Yuye Wu Anfei Li Honggang Wang Lingrang Kong Guihua Bai Shubing Liu | 2020 | Molecular Plant2020,13,9: | 8 |
| 5 | Construction of heparin-based hydrogel incorporated with Cu_(5.4)O ultrasmall nanozymes for wound healing and inflammation inhibition显示文摘Excessive production of inflammatory chemokines and reactive oxygen species(ROS)can cause a feedback cycle of inflammation response that has a negative effect on cutaneous wound healing.The use of wound-dressing materials that simultaneously absorb chemokines and scavenge ROS constitutes a novel‘weeding and uprooting’treatment strategy for inflammatory conditions.In the present study,a composite hydrogel comprising an amine-functionalized star-shaped polyethylene glycol(starPEG)and heparin for chemokine sequestration as well as Cu_(5.4)O ultrasmall nanozymes for ROS scavenging(Cu_(5.4)O@Hep-PEG)was developed.The material effectively adsorbs the inflammatory chemokines monocyte chemoattractant protein-1 and interleukin-8,decreasing the migratory activity of macrophages and neutrophils.Furthermore,it scavenges the ROS in wound fluids to mitigate oxidative stress,and the sustained release of Cu_(5.4)O promotes angiogenesis.In acute wounds and impaired-healing wounds(diabetic wounds),Cu_(5.4)O@Hep-PEG hydrogels outperform the standard-of-care product Promogram®in terms of inflammation reduction,increased epidermis regeneration,vascularization,and wound closure. | Yuan Peng Danfeng He Xin Ge Yifei Lu Yuanhao Chai Yixin Zhang Zhengwei Mao Gaoxing Luo Jun Deng Yan Zhang | 2021 | Bioactive Materials2021,6,10: | 7 |
| 6 | Catalytic pyrolysis of Pubescens to phenols over Ni/C catalyst显示文摘The pyrolysis of Pubescens over Ni/C catalyst was studied at 350°C in H2 flow.The presence of Ni/C catalyst efficiently improved the degradation of raw materials,and produced bio-oil with high content of phenols but low contents of acetic acid,furfural and water.In the reaction,Ni/C catalyst plays the role of catalytic decomposition and catalytic hydrogenation.The existence of the carbon carrier favors the formation of active Ni in small sizes with more defects,which results in high catalytic activity of Ni in biomass decomposition and selective production of phenols. | LUO Jia LI Jie SHEN DanFeng HE Ling TONG DongMei HU ChangWei | 2010 | Science China Chemistry2010,53,7: | 4 |
| 7 | Analysis of the Global Burden of Disease study highlights the trends in death and disability-adjusted life years of leukemia from 1990 to 2017显示文摘Background:The patterns of leukemia burden have dramatically changed in recent years.This study aimed to estimate the global trends of leukemiarelated death and disability-adjusted life-years(DALYs)from 1990 to 2017.Methods:The data was acquired from the latest version of the Global Burden of Disease(GBD)study.Estimated annual percentage changes(EAPCs)were calculated to estimate the trend of age-standardized rate(ASR)of death and DALYs due to leukemia and its main subtypes from 1990 to 2017.Results:Globally,the numbers of death and DALYs due to leukemia were 347.58×10^(3)(95%uncertainty interval[UI]=317.26×10^(3)-364.88×10^(3))and 11975.35×10^(3)(95%UI=10749.15×10^(3)-12793.58×10^(3))in 2017,with a 31.22% and 0.03% increase in absolute numbers from 1990 to 2017,respectively.Both of their ASR showed decreasing trends from 1990 to 2017 with the EAPCs being−1.04(95%confidence interval[CI]=(−1.10-−0.99)and−1.52(95%CI=−1.59-−1.44),respectively.Globally,the most pronounced decreasing trend of death and DALYs occurred in chronic myeloid leukemia with EAPCs of−2.76(95%CI=−2.88-−2.64)and−2.84(95%CI=−2.97-−2.70),respectively,while the trend increased in acute myeloid leukemia.The death and DALYs of leukemia decreased in most areas and countries with high socio-demographic index(SDI)including Bahrain,Finland,and Australia.Conclusions:The disease burden of death and DALYs due to leukemia decreased globally,and for most regions and countries from 1990 to 2017.However,the leukemia burden is still a substantial challenge globally and required adequate and affordable medical resources to improve the survival and quality of life of leukemia patients. | Zejin Ou Danfeng Yu Yuanhao Liang Wenqiao He Yongzhi Li Minyi Zhang Fangfei You Huan He Qing Chen | 2020 | Cancer Communications2020,40,11: | 4 |
| 8 | A model to determine the lake nutrient standards for drinking water sources in Yunnan-Guizhou Plateau Ecoregion, China显示文摘Lake eutrophication (LE) has become an increasingly severe environmental problem recently. However, there has been no nutrient standard established for LE control in many developing countries such as China. This study proposes a structural equation model to assist in the establishment of a lake nutrient standard for drinking water sources in Yunnan-Guizhou Plateau Ecoregion (Yungui Ecoregion), China. The modeling results indicate that the most predictive indicator for designated use-attainment is total phosphorus (TP) (total effect =-0.43), and chlorophyll a (Chl-a) is recommended as the second important indicator (total effect =-0.41). The model is further used for estimating the probability of use-attainment associated with lake water as a drinking water source and various levels of candidate criteria (based on the reference conditions and the current environmental quality standards for surface water). It is found that these candidate criteria cannot satisfy the designated 100% use-attainment. To achieve the short-term target (85% attainment of the designated use), TP and Chl-a values ought to be less than 0.02 mg/L and 1.4 μg/L, respectively. When used as a long-term target (90% or greater attainment of the designated use), the TP and Chl-a values are suggested to be less than 0.018 mg/L and 1 μg/L, respectively. | Danfeng Ji Beidou Xi Jing Su Shouliang Huo Li He Hongliang Liu Queping Yang | 2013 | Journal of Environmental Sciences2013,25,9: | 2 |
| 9 | Highly selective synthesis for 4,4′-bisphenol F from phenol and formaldehyde catalyzed with [C_4mim][HSO_4] ionic liquid显示文摘The effects of N-methylimidazole cation [Cnmim] with different alkyl chain lengths, the types of cations and anions of ionic liquids and the reaction parameters on the catalytic activity and the selectivity for 4,4′-bisphenol F were investigated. The hydrogen bonding between the hydroxyl of phenol and the C2-position hydrogen of imidazole moiety in hydrophilic imidazole-based ionic liquid has important influence on the selectivity for 4,4′-bisphenol F, and under the conditions of the molar ratio of phenol/[C4mim][HSO4] 1:1, reaction temperature65 °C and the theoretical molar ratio of phenol/formaldehyde 2:1, the selectivity for 4,4′-bisphenol F reached69.1%. Compared with the high phenol/formaldehyde ratio reported in literatures, the low molar ratio of phenol/formaldehyde and the low reaction temperature can greatly reduce energy consumption, and has important significance for industrial application. | Danfeng Wang Zhicheng He Zhimin Wu Ying Tan Yongfei Li Yuejin Liu | 2016 | Chinese Journal of Chemical Engineering2016,24,9: | 2 |

| 11 | Improved suspension quality and liquid level stability in stirred tanks with Rotor-Stator agitator based on CFD simulation显示文摘The solid-liquid mixing is an important operation unit in the preparation of composites by stirring casting.High quality composite materials need good homogeneity and stable liquid level.In this work,the performances of the Rotor-Stator agitator for solid suspension in stirred tank were investigated through CFD modeling,including the homogeneity,power consumption and liquid level stability.The Eulerian-Eulerian(E-E)multiphase model and the RNG k-εturbulence model were adopted for modeling the multiphase flow and the turbulence effects,respectively.The effect of various important parameters such as stirring speed,particle size,solid loading and the use of baffles were examined.Adding a stator structure with array holes outside the rotor can optimize the flow pattern,thereby improving the mixing uniformity and liquid level stability.The homogeneity and liquid level stability attained by the Rotor-Stator agitator were better than those for the A200(an axial-flow agitator)and the Rushton(a radial-flow agitator). | Cuicui Yin Jiazhen He Yongnan Xiong Zhibo Zhang Xing Luo Yao Shu Danfeng Long Kaihong Zheng | 2023 | Particuology2023,,11: | 0 |

| 13 | Task Coordination Organization Model and the Task Allocation Algorithm for Resource Contention of the Syncretic System显示文摘At present, robot embedded systems have some common problems such as closure and poor dynamic evolution. Aiming at resolving this situation, our paper focuses on improvements to the robot embedded system and sets up a new robot system architecture, and we propose a syncretic mechanism of a robot and Soft Man(SM). In the syncretic system, the structural organization of the Soft Man group and its modes are particularly important in establishing the task coordination mechanism. This paper, therefore, proposes a coordination organization model based on the Soft Man group, and studies in detail the process of task allocation for resource contention, which facilitates a rational allocation of system resources. During our research, we introduced Resource Requirement Length Algorithm(RRLA) to calculate the resource requirements of the task and a resource conformity degree allocation algorithm of Resource Conformity Degree Algorithm(RCDA) for resource contention. Finally, a comparative evaluation of RCDA with five other frequently used task allocation algorithms shows that RCDA has higher success and accuracy rates with good stability and reliability. | Danfeng Wu Guangping Zeng Di He Zhaopeng Qian Qingchuan Zhang | 2016 | Tsinghua Science and Technology2016,21,4: | 0 |
| 14 | Low-complexity iterative equalization for OTFS based on alternating minimization显示文摘To achieve robust communication in high mobility scenarios,an iterative equalization algorithm based on alternating minimization(AM)is proposed for the orthogonal time frequency space(OTFS)system.The algorithm approximates the equalization problem to a convex function optimization problem in the real-valued domain and solves the problem iteratively using the AM algorithm.In the iterative process,the complexity of the proposed algorithm is reduced further based on the study of the cyclic structure and sparse property of the OTFS channel matrix in the delay-Doppler(DD)domain.The new method for OTFS is simulated and verified in a high-speed mobile scenario and the results show that the proposed equalization algorithm has excellent bit error rate performance with low complexity. | HE Xin JIA Haoxiang SUN Yutong ZHOU Zijian ZHAO Danfeng | 2023 | Journal of Systems Engineering and Electronics2023,34,4: | 0 |
| 15 | Vertical Differential Structural Deformation of the Main Strike-slip Fault Zones in the Shunbei Area,Central Tarim Basin:Structural Characteristics,Deformation Mechanisms,and Hydrocarbon Accumulation Significance显示文摘Vertical differential structural deformation(VDSD),one of the most significant structural characteristics of strike-slip fault zones(SSFZs)in the Shunbei area,is crucial for understanding deformation in the SSFZ and its hydrocarbon accumulation significance.Based on drilling data and high-precision 3-D seismic data,we analyzed the geometric and kinematic characteristics of the SSFZs in the Shunbei area.Coupled with the stratification of the rock mechanism,the structural deformations of these SSFZs in different formations were differentiated and divided into four deformation layers.According to comprehensive structural interpretations and comparisons,three integrated 3-D structural models could describe the VDSD of these SSFZs.The time-space coupling of the material basis(rock mechanism stratification),changing dynamic conditions(e.g.,changing stress-strain states),and special deformation mechanism of the en echelon normal fault array uniformly controlled the formation of the VDSD in the SSFZs of the Shunbei area.The VDSD of the SSFZs in this area controlled the entire hydrocarbon accumulation process.Multi-stage structural superimposing deformation influenced the hydrocarbon migration,accumulation,distribution,preservation,and secondary adjustments. | TIAN Fanglei HE Dengfa CHEN Jiajun MAO Danfeng | 2022 | Acta Geologica Sinica(English Edition)2022,96,4: | 0 |
| 16 | Distribution, evolution and structural properties of Wushenqi paleo-uplift in Ordos Basin, NW China显示文摘This paper depicts the distribution of the Wushenqi paleo-uplift in the Ordos Basin by using the latest drilling and seismic data, and analyzes the tectonic evolution of the paleo-uplift with the support of Bischke curve and balanced section. The compressional Wushenqi paleo-uplift which developed in the Early Caledonian orogeny(Huaiyuan orogeny) is approximately a ellipse extending in S-N direction. Its long axis is about 194 km and short axis is about 55-94 km in nearly W-E direction. The denudation thickness and area of the Cambrian in the core are 170-196 m and 11 298 km^(2), respectively. It was mainly formed during the Huaiyuan orogeny according to the chronostratigraphic framework. It was in the embryonic stage in the Middle-Late Cambrian, denuded after developed obviously at the end of Late Cambrian. The paleo-uplift of the 3rd member of the Ordovician Majiagou Formation was reactivated and reduced in area. In the sedimentary period of the Ma 4 Member-pre-Carboniferous, the paleo-uplift experienced non-uniform uplift and denudation. It entered the stable period of burial and preservation in the Carboniferous and later period. The Wushenqi paleo-uplift was formed on the weak area of the basement and tectonic belts, into an compressional structure with irregular morphology, under the control of the non-coaxial compression in the south and north and the stress transmitted by the uplift in the basin. The Wushenqi paleo-uplift has a controlling effect on the sedimentary reservoirs and hydrocarbon accumulation. | MAO Danfeng HE Dengfa BAO Hongping WEI Liubin XU Yanhua CHENG Xiang GOU Junyi WU Saijun | 2023 | Petroleum Exploration and Development2023,50,4: | 0 |
