1Ideal cardiovascular health and incidence of atherosclerotic cardiovascular disease among Chinese adults:the China-PAR project显示文摘Existing evidence on the relationship between cardiovascular health(CVH) metrics and cardiovascular disease(CVD) was primarily derived from western populations. We aimed to evaluate the benefits of ideal CVH metrics on preventing incident atherosclerotic CVD(ASCVD) in Chinese population. This study was conducted among 93,987 adults from the China-PAR project(Prediction for ASCVD Risk in China) who were followed up until 2015. Cox proportional hazard regression models were used to estimate the hazard ratios(HRs) and their corresponding 95% confidence intervals(CIs) of CVH metrics for the risk of ASCVD, including coronary heart disease(CHD), stroke and ASCVD death. We further estimated the population-attributable risk percentage(PAR%) of these metrics in relation to each outcome. We observed gradient inverse associations between the number of ideal CVH metrics and ASCVD incidence. Compared with participants having ≤2 ideal CVH metrics, the multivariable-adjusted HRs(95% CIs) of ASCVD for those with 3, 4, 5, 6 and 7 ideal CVH metrics were 0.83(0.74–0.93), 0.66(0.59–0.74), 0.55(0.48–0.61), 0.44(0.38–0.50) and 0.24(0.18–0.31), respectively(P for trend <0.0001). Approximately 62.1% of total ASCVD, 38.7% of CHD, 66.4% of stroke, and 60.5% of ASCVD death were attributable to not achieving all the seven ideal CVH metrics. After adjusting effects of ideal health factors, having four ideal health behaviors could independently bring adults health benefits in preventing 17.4% of ASCVD, 18.0% of CHD, 16.7% of stroke, and 10.1% of ASCVD death. Among all the seven CVH metrics, to keep with ideal blood pressure(BP) implied the largest public health gains against various ASCVD events(PAR% between 33.0% and 47.2%), while ideal diet was the metric most difficult to be achieved in the long term. Our study indicates that the more ideal CVH metrics adults have, the less ASCVD burden there is in China. Special efforts of health education and behavior modification should be made on keeping ideal BP and dietary habits in general Chinese population to prevent the epidemic of ASCVD.Chao Han Fangchao Liu Xueli Yang Jichun Chen Jianxin Li Jie Cao Ying Li Chong Shen Ling Yu Zhendong Liu Xianping Wu Liancheng Zhao Dongshen Hu Xiangfeng Lu Xigui Wu Dongfeng Gu 2018Science China(Life Sciences)2018,61,5:60
2Performance of RegCM4 over Major River Basins in China显示文摘A long-term simulation for the period 1990–2010 is conducted with the latest version of the International Centre for Theoretical Physics' Regional Climate Model(RegCM4), driven by ERA-Interim boundary conditions at a grid spacing of 25 km. The Community Land Model(CLM) is used to describe land surface processes, with updates in the surface parameters,including the land cover and surface emissivity. The simulation is compared against observations to evaluate the model performance in reproducing the present day climatology and interannual variability over the 10 main river basins in China,with focus on surface air temperature and precipitation. Temperature and precipitation from the ERA-Interim reanalysis are also considered in the model assessment. Results show that the model reproduces the present day climatology over China and its main river basins, with better performances in June–July–August compared to December–January–February(DJF).In DJF, we find a warm bias at high latitudes, underestimated precipitation in the south, and overestimated precipitation in the north. The model in general captures the observed interannual variability, with greater skill for temperature. We also find an underestimation of heavy precipitation events in eastern China, and an underestimation of consecutive dry days in northern China and the Tibetan Plateau. Similar biases for both mean climatology and extremes are found in the ERA-Interim reanalysis, indicating the difficulties for climate models in simulating extreme monsoon climate events over East Asia.Xuejie GAO Ying SHI Zhenyu HAN Meili WANG Jia WU Dongfeng ZHANG Ying XU Filippo GIORGI 2017Advances in Atmospheric Sciences2017,34,4:33
3A genome-wide landscape of mRNAs,lncRNAs,and circRNAs during subcutaneous adipogenesis in pigs显示文摘Background: Preadipocyte differentiation plays a critical role in subcutaneous fat deposition in pigs.However,the roles of different RNAs,such as messenger RNAs(mRNAs),long non-coding RNAs(lncRNAs),and circular RNAs(circRNAs) in the differentiation process of subcutaneous preadipocytes,are still largely unclear.In the present study,a transcriptome analysis,including the analysis of mRNAs,lncRNAs,and circRNAs,during different differentiation stages,namely,day 0(D0),day 2(D2),day 4(D4),and day 8(D8),of subcutaneous preadipocytes from Chinese Erhualian pigs was performed.Results: A total of 1554,470,1344,1777,and 676 differentially expressed(DE) mRNAs,112,58,95,136,and 93 DE lncRNAs,and 902,787,710,932,and 850 DE circRNAs were identified between D2 and D0,between D4 and D2,between D8 and D4,between D4 and D0,and between D8 and D0,respectively.Furthermore,functional enrichment analysis showed that the common DE mRNAs during the entire differentiation process were mainly involved in lipid metabolic and cell differentiation processes.Additionally,co-expression network analysis identified the potential lncRNAs related to adipogenesis,e.g.,MSTRG.131380 and MSTRG.62128.Conclusions: Our study provides new insights of the expression changes of RNAs during adipogenic differentiation,which might contribute to the phenotype of subcutaneous adipogenesis.These results greatly improve our understanding of the molecular mechanisms regulating subcutaneous fat deposition in pigs.Xin Liu Kaiqing Liu Baosen Shan Shengjuan Wei Dongfeng Li Haiyin Han Wei Wei Jie Chen Honglin Liu Lifan Zhang 2019Journal of Animal Science and Biotechnology2019,10,1:5
4Isolation and Characterization of Fucoidans from Five Brown Algae and Evaluation of Their Antioxidant Activity显示文摘In this study, we evaluated the chemical property and antioxidant activity of fucoidans isolated from brown algae, Laminaria japonica(LJF), Lessonia nigrescens(LNF), Lessonia trabeculata(LTF), Ascophyllum mackaii(AMF), and Ecklonia maxima(EMF). LJF was less in sulfate content(14.16%) and more in galactose and mannose content(1.08 and 0.68) than the documented early. EMF contained 20%–30% of sulfate and fucose, 0.97 in molar ratio which was lower than that of sulfate to other four fucoidans(1.21–1.41). AMF(162 kDa) and EMF(150 kDa) were the first two largest in molecular weight, which were followed by LJP(126 kDa), LNF(113 kDa) and LTF(105 kDa). The fucoidans isolated these algae showed a wide range of antioxidant activity in vitro. It was found that the reducing power of the isolated fucoidans was positively correlated with their sulfate content and molecular weight. In addition, LNF and LTF at low concentrations exhibited high superoxide and hydroxyl radical scavenging activity. This demonstrated that low molecular weight fucoidans may perform a high antioxidant activity.QU Guiyan LIU Xu WANG Dongfeng YUAN Yi HAN Lijun 2014Journal of Ocean University of China2014,13,5:3

7Enhanced Performance of Denitrifying Sulfide Removal Process by 1,2-Naphthoquinone-4-Sulphonate显示文摘The denitrifying sulfide removal(DSR) process with bio-granules comprising both heterotrophic and autotrophic denitrifiers can simultaneously convert nitrate, sulfide and acetate species into di-nitrogen gas, elemental sulfur and carbon dioxide, respectively, at high loading rates. This study has determined that the reaction rate of sulfide oxidized into sulfur could be enhanced in the presence of 1,2-naphthoquinone-4-sulphonate(NQS). The presence of NQS mitigated the inhibition effects of sulfide species on denitrification. Furthermore, the reaction rates of nitrate and acetate to nitrogen gas and CO_2, respectively, were also promoted in the presence of NQS, thereby enhancing the performance of DSR granules. The advantages and disadvantages of applying the NQS-DSR process are discussed.Liu Chunshuang Han Kang Zhao Dongfeng Guo Yadonag Liu Lihong Liu Fang Zhao Chaocheng 2016China Petroleum Processing & Petrochemical Technology2016,18,1:1

14Caching Algorithm with a Novel Cost Model to Deliver Content and Its Interest over Content Centric Networks显示文摘Recently the content centric networks(CCNs) have been advocated as a new solution to design future networks. In the CCNs, content and its interest are delivered over the content store and pending interest table, respectively, where both have limited capacities. Therefore, how to design the corresponding algorithms to efficiently deliver content and inertest over them becomes an important issue. In this paper, based on the analysis of content distribution, status of content store, and pending interest, we propose a novel caching algorithm with which the resources of content store and pending interest table can be efficiently used. Simulation results prove that the proposal can outperform the conventional methods.SU Zhou FANG Dongfeng HAN Bo 2015China Communications2015,12,7:1
15In-situ revealing the degradation mechanisms of Pt film over 1000℃显示文摘Degradation of a metallic film under harsh thermal-mechanical-electrical coupling field conditions determines its service temperature and lifetime.In this work,the self-heating degradation behaviors of Pt thin films above 1000℃were studied in situ by TEM at the nanoscale.The Pt films degraded mainly through void nucleation and growth on the Pt-SiN_(x)interface.Voids preferentially formed at the grain boundary and triple junction intersections with the interface.At temperatures above 1040℃,the voids nucleated at both the grain boundaries and inside the Pt grains.A stress simulation of the suspended membrane suggests the existence of local tensile stress in the Pt film,which promotes the nucleation of voids at the Pt-Si Nxinterface.The grain-boundary-dominated mass transportation renders the voids grow preferentially at GBs and triple junctions in a Pt film.Additionally,under the influence of an applied current,the voids that nucleated inside Pt grains grew to a large size and accelerated the degradation of the Pt film.Dongfeng Ma Shengcheng Mao Jiao Teng Xinliang Wang Xiaochen Li Jin Ning Zhipeng Li Qing Zhang Zhiyong Tian Menglong Wang Ze Zhang Xiaodong Han 2021Journal of Materials Science & Technology2021,,36:0

17Genetic Architecture of Childhood Kidney and Urological Diseases in China显示文摘Kidney disease is manifested in a wide variety of phenotypes,many of which have an important hereditary component.To delineate the genotypic and phenotypic spectrum of pediatric nephropathy,a multicenter registration system is being imple-mented based on the Chinese Children Genetic Kidney Disease Database(CCGKDD).In this study,all the patients with kidney and urological diseases were recruited from 2014 to 2020.Genetic analysis was conducted using exome sequencing for families with multiple affected individuals with nephropathy or clinical suspicion of a genetic kidney disease owing to early-onset or extrarenal features.The genetic diagnosis was confirmed in 883 of 2256(39.1%)patients from 23 provinces in China.Phenotypic profiles showed that the primary diagnosis included steroid-resistant nephrotic syndrome(SRNS,23.5%),glomerulonephritis(GN,32.2%),congenital anomalies of the kidney and urinary tract(CAKUT,21.2%),cystic renal disease(3.9%),renal calcinosis/stone(3.6%),tubulopathy(9.7%),and chronic kidney disease of unknown etiology(CKDu,5.8%).The pathogenic variants of 105 monogenetic disorders were identified.Ten distinct genomic disorders were identified as pathogenic copy number variants(CNVs)in 11 patients.The diagnostic yield differed by subgroups,and was highest in those with cystic renal disease(66.3%),followed by tubulopathy(58.4%),GN(57.7%),CKDu(43.5%),SRNS(29.2%),renal calcinosis/stone(29.3%)and CAKUT(8.6%).Reverse phenotyping permitted correct identification in 40 cases with clinical reassessment and unexpected genetic conditions.We present the results of the largest cohort of children with kidney disease in China where diagnostic exome sequencing was performed.Our data demonstrate the utility of family-based exome sequencing,and indicate that the combined analysis of genotype and phenotype based on the national patient registry is pivotal to the genetic diagnosis of kidney disease.Ye Fang Hua Shi Tianchao Xiang Jiaojiao Liu Jialu Liu Xiaoshan Tang Xiaoyan Fang Jing Chen Yihui Zhai Qian Shen Guomin Li Li Sun Yunli Bi Xiang Wang Yanyan Qian Bingbing Wu Huijun Wang Wenhao Zhou Duan Ma Jianhua Mao Xiaoyun Jiang Shuzhen Sun Ying Shen Xiaorong Liu Aihua Zhang Xiaowen Wang Wenyan Huang Qiu Li Mo Wang Xiaojie Gao Yubin Wu Fang Deng Ruifeng Zhang Cuihua Liu Li Yu Jieqiu Zhuang Qing Sun Xiqiang Dang Haitao Bai Ying Zhu Siguang Lu Bili Zhang Xiaoshan Shao Xuemei Liu Mei Han Lijun Zhao Yuling Liu Jian Gao Ying Bao Dongfeng Zhang Qingshan Ma Liping Zhao Zhengkun Xia Biao Lu Yulong Wang Mengzhun Zhao Jianjiang Zhang Shan Jian Guohua He Huifeng Zhang Bo Zhao Xiaohua LI Feiyan Wang Yufeng Li Hongtao Zhu Xinhui Luo Jinghai Li Jia Rao Hong Xu 2021Phenomics2021,1,3:0
18Analysis of Microstructure of Reactor Pressure Vessel Steel due to Thermal Aging Effect by Small-angle Neutron Scattering显示文摘Reactor pressure vessels are of great importance for nuclear power safety and play an extremely important role in the safe operation of reactors and in preventing nuclear leakage.As material microstructure probe,neutrons have the advantages of high penetrability,ability to distinguish between adjacent nuclide and sensitivity to magnetism.The small-angle neutron scattering can accurately obtain the size distribution,volume fraction and composition of the defects of the nanosized copper clusters in the pressure vessel steel matrix,revealing the microstructure mechanism of the macroscopic mechanical properties.The thermal aging supervision samples from a nuclear power plant in China had been analyzed by small-angle neutron scattering.LI Bonan WANG Zijun LIU Rongdeng HAN Songbai SUN Kai CHEN Dongfeng LIU Yuntao WANG Chenglong TONG Zhenfeng LI Tianfu 2018中国原子能科学研究院年报2018,,1:0
19Characterization of a Triticum aestivum-Aegilops germplasm line presenting reduced plant height and early maturation显示文摘Plant height plays an important role in the potential and stability of crop yields and represents one of the most important agronomic traits of wheat. Although more than 30 dwarfing genes have been identified in wheat, only a few are used in wheat breeding, which has narrowed the genetic basis of newly developed varieties. Therefore, continually identifying new dwarfing genes is required to produce improved wheat cultivars. TA001 is a new germplasm line marked by reduced plant height and early maturation, and it was derived from a hybridization between the common wheat Yannong 15 and the Aegilops ventricosa × Aegilops cylindrica amphiploid SDAU18. In this study, cytological observations, agronomic trait examinations, genomic in situ hybridization(GISH), multicolor genomic in situ hybridization(mc-GISH), multicolor fluorescence in situ hybridization(mc-FISH), SSR analysis and seed storage protein electrophoresis were combined to determine the cytological stability, main agronomic traits, chromosomal constituents and seed storage protein subunits of TA001. Twenty-one bivalents were observed in most of the pollen mother cells at metaphase I(PMCs MI) in TA001, which housed 42 chromosomes, and the chromosomes in most pollen mother cells at anaphase I(PMCs AI)displayed 21/21 segregation. Twenty bivalents plus two univalents were simultaneously observed in most of the PMCs MI of the hybrid F_1 between TA001 and Yannong 15. TA001 possessed all chromosomes from genomes A, B and D except for chromosome 7B, which was replaced by one pair of N-genome chromosomes from Aegilops ventricosa. Several pairs of chromosomes in TA001 exhibited different FISH patterns from the equivalent chromosomes in Yannong 15. TA001 housed alien genetic materials from Aegilops ventricosa and Aegilops cylindrica and possessed new glutenin and gliadin subunits specific to SDAU18, as revealed by molecular marker analysis and protein electrophoresis respectively.Yuhai Wang Qingdian Han Fang He Yinguang Bao Dongfeng Ming Honggang Wang 2017The Crop Journal2017,5,3:0
