1Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
2TaSCL14,a Novel Wheat(Triticum aestivum L.)GRAS Gene,Regulates Plant Growth,Photosynthesis,Tolerance to Photooxidative Stress,and Senescence显示文摘Rates of photosynthesis,tolerance to photooxidative stress,and senescence are all important physiological factors that affect plant development and thus agricultural productivity.GRAS proteins play essential roles in plant growth and development as well as in plant responses to biotic and abiotic stresses.So far few GRAS genes in wheat(Triticum aestivum L.)have been characterized.A previous transcriptome analysis indicated that the expression of a GRAS gene(TaSCL14) was induced by high-light stress in Xiaoyan 54(XY54),a common wheat cultivar with strong tolerance to high-light stress.In this study,TaSCL14 gene was isolated from XY54 and mapped on chromosome 4A.TaSCL14 was expressed in various wheat organs,with high levels in stems and roots.Our results confirmed that TaSCL14 expression was indeed responsive to high-light stress.Barley stripe mosaic virus(BSMV)-based virus-induced gene silencing(VIGS)of TaSCL14 in wheat was performed to help characterize its potential functions.Silencing of TaSCL14 resulted in inhibited plant growth,decreased photosynthetic capacity,and reduced tolerance to photooxidative stress.In addition,silencing of TaSCL14 in wheat promoted leaf senescence induced by darkness.These results suggest that TaSCL14 may act as a multifunctional regulator involved in plant growth,photosynthesis,tolerance to photooxidative stress,and senescence.Kunmei Chen Hongwei Li Yaofeng Chen Qi Zheng Bin Li Zhensheng Li 2015Journal of Genetics and Genomics2015,42,1:11
3Application of biochar-based materials in environmental remediation:from multi-level structures to specific devices显示文摘The development of biochar has triggered a hot-spot in various research fields including agriculture,energy,environment,and materials.Biochar-based materials provide a novel approach against environmental challenging issues.Considering the rapid development of biochar materials,this review serves as a valuable platform to summarize the recent progress on the theoretical investigation and engineering applications of biochar materials in environmental remediation.For a better understanding of the structure-application relationships,the structural properties of biochar from macroscopic and microscopic aspects are summarized.The multilevel structures including elements,phases,surface chemistry,and molecular are highlighted to elucidate the multi-functional properties of biochars.Sorption,catalysis,redox reaction,and biological activity of biochar are briefly illustrated,which influence the transport,transformation,and removal of organic and inorganic pollutants in the environments.According to the multi-level structures and structure-application relationships of biochar,specific biochar-based materials and devices have been designed for practical environmental application.The important progress on the functionalization and device of biochar-based materials,including magnetic biochars,2D and 3D biochar-based macrostructures,immobilized microorganism on biochar,and biochar-amended biofilters are highlighted.The environmental friendliness and sustainability of biochar-based materials,considering the whole cycle from synthesis to application,are evaluated.Lun Lu Wentao Yu Yaofeng Wang Kun Zhang Xiaomin Zhu Yuecan Zhang Yajing Wu Habib Ullah Xin Xiao Baoliang Chen 2020Biochar2020,2,1:11

7Robust model predictive control for greenhouse temperature based on particle swarm optimization显示文摘Application of model predictive control(MPC)in horticultural practice requires detailed models.However,even highly sophisticated greenhouse climate models are often known to have unknown dynamics affected by bounded uncertainties.To enforce robustness during the controller design stage,this paper proposes a particle swarm optimization(PSO)-based robust MPC strategy for greenhouse temperature systems.The strategy is based on a nonlinear physical temperature affine model.The robust MPC technique requires online solution of a minimax optimal control problem,which optimizes the tradeoff between set point tracking and cost requirements reduction.The minimax optimization problem is reformulated to a nonlinear programming problem with constraints.PSO is used to solve the reformulated problem and priority ranking of constraint fitness is proposed to guarantee that the constraints are satisfied.The results of simulations performed using the proposed control system show that the controller can effectively achieve the set point in the presence of disturbances and that it offers more suitable control variables,higher control precision,and stronger robustness than the conventional MPC.Lijun Chen Shangfeng Du Yaofeng He Meihui Liang Dan Xu 2018Information Processing in Agriculture2018,5,3:4

10Comparative study of estimation methods for genomic breeding values显示文摘Estimation of genomic breeding values is important in genomic selection. Bayesian and BLUP methods are the main techniques employed. In this study,we conducted a comparative study of Bayes A, Bayes B,Bayes Cp and GBLUP methods in simulated data and real data of Chinese Holstein cattle. Results showed that, in simulated data, the accuracies of all methods were all similarly elevated with the increase of reference population size, but they made different responses to the changes of marker number or QTL number. In real data of Chinese Holstein cattle, Bayes A generated the highest accuracy almost for all six traits, and GBLUP performed as well as Bayes A for the traits of milk yield, fat yield and protein yield, while for the trait of fat percentage, protein percentage and somatic cell score, three Bayesian methods showed superior to GBLUP. Comprehensively analyzing above results, it can be speculated that accuracies of the three Bayesian methods are not only influenced by the absolute value of QTL number or marker number, but may also be influenced by the ratio of QTL number to marker number. And there is at least one kind of Bayesian methods performing better than GBLUP, when the ratio of QTL number versus marker number is very small or involving large-effect QTL.Chonglong Wang Qin Zhang Li Jiang Rong Qian Xiangdong Ding Yaofeng Zhao 2016Science Bulletin2016,61,5:3

12Key Technologies and Application of Edge Computing显示文摘Cloud computing faces a series of challenges,such as insufficient bandwidth,unsatisfactory real-time,privacy protection,and energy consumption.To overcome the challenges,edge computing emerges.Edge computing refers to a process where the open platform that converges the core capabilities of networks,computing,storage,and applications provides intelligent services at the network edge near the source of the objects or data to meet the critical requirements for agile connection,real-time services,data optimization,application intelligence,security and privacy protection of industry digitization.Edge computing consists of three elements:edge,computing,and intelligence.Edge computing and the Internet of Things(IoT)mutually create,and edge computing and cloud computing complement each other.In the architecture of edge computing,resources are distributed to the edge nodes,and therefore the storage system is near users while the computation function is near data.In this way,the stress on the backbone network can be lessened.With this architecture,the existing key technologies for computation,networks,and storage will change significantly.ZTE’s edge computing solutions can ensure the service quality of operators and greatly enhance the experience of mobile users.TU Yaofeng DONG Zhenjiang YANG Hongzhang 2017ZTE Communications2017,15,2:3
13Strategic analysis of China’s geothermal energy industry显示文摘China is an early user of geothermal energy,and its direct use ranks first in the world.Recent national strategies and policies have enabled China’s geothermal energy industry to enter a new era with important development opportunities.This paper investigates the strengths,weaknesses,opportunities,and threats(SWOT)to China’s geothermal energy industry from political,economic,social,and technological(PEST)perspectives.SWOT–PEST analysis indicates that the resources,market,and technological foundation exist for the large-scale development of China’s geothermal energy industry.However,it experiences constraints,such as unclear resource distributions,incomplete development of government regulations,incomplete implementation of national policies,unclear authority between governmental administrative systems,and lack of uniform technical standards and codes.Therefore,future development strategies have been proposed to provide technical support and policy tools for geothermal energy development.The recommendations to ensure its healthy and sustainable development include improving resource exploration,rationalizing administration systems,enhancing policy guidance and financial support,and cultivating geothermal talent.Hao GONG Baicun WANG Haijun LIANG Zuoxian LUO Yaofeng CAO 2021Frontiers of Engineering Management2021,8,3:2
