| 1 | DNA image cytometry test for primary screening of esophageal cancer: a population-based multi-center study in high-risk areas in China显示文摘Objective: To evaluate the feasibility of DNA image cytometry(DNA-ICM) as a primary screening method for esophageal squamous cell cancer(ESCC).Methods: A total of 5,382 local residents aged 40–69 years from three high-risk areas in China(Linzhou in Henan province, Feicheng in Shandong province and Cixian in Hebei province) from 2008 to 2011 were recruited in this population-based screening study. And 2,526 subjects declined to receive endoscopic biopsy examination with Lugol's iodine staining, while 9 and 815 subjects were excluded from liquid-based cytology and DNA-ICM test respectively due to slide quality. Finally, 2,856, 5,373 and 4,567 subjects were enrolled in the analysis for endoscopic biopsy examination, liquid-based cytology and DNA-ICM test, respectively. Sensitivity(SE), specificity(SP), negative predictive values(NPV) and positive predictive values(PPV) as well as their 95% confidence intervals(95% CI) for DNA-ICM, liquid-based cytology and the combination of the two methods were calculated. Receiver operating characteristic(ROC) curves were applied to determine the cutoff point of DNA-ICM for esophageal cancer.Results: DNA-ICM results were significantly correlative with esophageal cancer and precancer lesions(χ~2=18.016, P<0.001). The cutoff points were 5,802, 5,803 and 8,002 based on dissimilar pathological types of low grade intraepithelial neoplasia(LGIN), high grade intraepithelial neoplasia(HGIN), and ESCC, respectively, and 5,803 was chosen in this study considering the SE and SP. The SE, SP, PPV, NPV of DNA-ICM test(cutoff point 5,803) combined with liquid-based cytology [threshold atypical squamous cells of undetermined significance(ASCUS)] were separately 72.1%(95% CI: 70.3%-73.9%), 43.3%(95% CI: 41.3%-45.3%), 22.8%(95% CI: 21.1%-24.5%) and 87.0%(95% CI: 85.7%-88.3%) for LGIN, 85.7%(95% CI: 84.3%-87.1%), 41.3%(95% CI: 39.3%-43.3%), 4.6%(95% CI: 3.8%-5.4%) and 98.9%(95% CI: 98.5%-99.3%) for HGIN, and 96.0%(95% CI: 95.2%-96.8%), 40.8%(95% CI: 38.8%-42.8%), 1.7%(95% CI: 1.2%-2.2%) and 99.9%(95% CI: 99.8%-100.0%) for ESCC.Conclusions: It is possible to use DNA-ICM test as a primary screening method before endoscopic screening for esophageal cancer. | Meng Wang Changqing Hao Qing Ma Guohui Song Shanrui Ma Deli Zhao Lin Zhao Xinqing Li Wenqiang Wei | 2016 | Chinese Journal of Cancer Research2016，28，4： | 15 |
| 2 | A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM. | Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON | 2020 | Science China Earth Sciences2020，63，8： | 7 |
| 3 | Structure and properties of an ultra-high strength 7xxx aluminum alloy contained Sc and Zr显示文摘An ultra-high strength aluminum alloy was produced by casting and then extruded to rods.The effect of heat treatment on the microstructure and mechanical properties of the alloy was investigated.After single ageing(120℃,24 h),the tensile strength was 812.4 MPa and the elongation was 6.2%.After retrogression reaging(RRA),the tensile strength was 751.2 MPa and the elongation was 6.4%.The strengthening mechanism is considered as fine grain strengthening,substructure strengthening and dispersion strengthening by Al_3(Sc,Zr). | Xiaoyuan Dai Changqing Xia Xiaomin Peng Ke Ma | 2008 | Journal of University of Science and Technology Beijing2008，15，3： | 7 |
| 4 | Drosophila RecQ5 is required for efficient SSA repair and suppression of LOH in vivo显示文摘RecQ5 in mammalian cells has been suggested to suppress inappropriate homologous recombination.However,the specific pathway(s)in which it is involved and the underlining mechanism(s)remain poorly understood.We took advantage of genetic tools in Drosophila to investigate how Drosophila RecQ5(dRecQ5)functions in vivo in homologous recombination-mediated double strand break(DSB)repair.We generated null alleles of dRecQ5 using the targeted recombination technique.The mutant animals are homozygous viable,but with growth retardation during development.The mutants are sensitive to both exogenous DSB-inducing treatment,such as gamma-irradiation,and endogenously induced double strand breaks(DSBs)by I-Sce I endonuclease.In the absence of dRecQ5,single strand annealing(SSA)-mediated DSB repair is compromised with compensatory increases in either inter-homologous gene conversion,or non-homologous end joining(NHEJ)when inter-chromosomal homologous sequence is unavailable.Loss of function of dRecQ5 also leads to genome instability in loss of heterozygosity(LOH)assays.Together,our data demonstrate that dRecQ5 functions in SSA-mediated DSB repair to achieve its full efficiency and in suppression of LOH in Drosophila. | Yixu Chen Wen Dui Zhongsheng Yu Changqing Li Jun Ma Renjie Jiao | 2010 | Protein & Cell2010，1，5： | 5 |
| 5 | Methane dry reforming on Ni/La_2Zr_2O_7 treated by plasma in different atmospheres显示文摘A series of Ni/La2Zr2O7 pyrochlore catalysts prepared by impregnation method and treated by dielectric barrier discharge(DBD) plasma in different atmospheres and varied sequences were prepared and applied for dry reforming of methane(DRM). It is found that all of the plasma treated catalysts show evidently improved activity and coke resistance in comparison with the non-plasma treated one. The best performance is achieved on Ni/La2Zr2O7–H2P–C,a catalyst treated in H2 plasma before calcination. TGA-DSC and SEM demonstrate that carbon deposition is significantly suppressed on all of the plasma treated samples. Moreover,XRD and TEM results testify that both Ni O and Ni sizes on the calcined and reduced samples treated by plasma are also decreased,which results in higher Ni metal dispersion on the reduced and used catalysts and enhances the interactions between Ni sites and the support. It is believed that these are the inherent reasons accounting for the promotional effects of plasma treatment on the reaction performance of the Ni/La2Zr2O7 pyrochlore catalysts. | Honggen Peng Youhe Ma Wenming Liu Xianglan Xu Xiuzhong Fang Jie Lian Xiang Wang Changqing Li Wufeng Zhou Ping Yuan | 2015 | Journal of Energy Chemistry2015，24，4： | 4 |
| 6 | Whole Genome Analyses of Chinese Population and De Novo Assembly of A Northern Han Genome显示文摘To unravel the genetic mechanisms of disease and physiological traits,it requires comprehensive sequencing analysis of large sample size in Chinese populations.Here,we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative(CASPMI)project launched by the Chinese Academy of Sciences,including the de novo assembly of a northern Han reference genome(NH1.0)and whole genome analyses of 597 healthy people coming from most areas in China.Given the two existing reference genomes for Han Chinese(YH and HX1)were both from the south,we constructed NH1.0,a new reference genome from a northern individual,by combining the sequencing strategies of PacBio,10×Genomics,and Bionano mapping.Using this integrated approach,we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1.In order to generate a genomic variation map of Chinese populations,we performed the whole-genome sequencing of 597 participants and identified 24.85 million(M)single nucleotide variants(SNVs),3.85 M small indels,and 106,382 structural variations.In the association analysis with collected phenotypes,we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males.Moreover,significant genetic diversity in MTHFR,TCN2,FADS1,and FADS2,which associate with circulating folate,vitamin B12,or lipid metabolism,was observed between northerners and southerners.Especially,for the homocysteine-increasing allele of rs1801133(MTHFR 677T),we hypothesize that there exists a “comfort”zone for a high frequency of 677T between latitudes of 35–45 degree North.Taken together,our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine. | Zhenglin Du Liang Ma Hongzhu Qu Wei Chen Bing Zhang Xi Lu Weibo Zhai Xin Sheng Yongqiao Sun Wenjie Li Meng Lei Qiuhui Qi Na Yuan Shuo Shi Jingyao Zeng Jinyue Wang Yadong Yang Qi Liu Yaqiang Hong Lili Dong Zhewen Zhang Dong Zou Yanqing Wang Shuhui Song Fan Liu Xiangdong Fang Hua Chen Xin Liu Jingfa Xiao Changqing Zeng | 2019 | Genomics, Proteomics & Bioinformatics2019，17，3： | 4 |
| 7 | Efficacy of endoscopic treatment on patients with severe dysplasia/carcinoma in situ of esophageal squamous cell carcinoma: A prospective cohort study显示文摘Objective: To explore the natural history of severe dysplasia/carcinoma in situ(SD/CIS) patients and to evaluate the efficacy of endoscopic treatment to SD/CIS patients.Methods: Between January 2005 and December 2009, a population-based prospective screening program on esophageal squamous cell carcinoma(ESCC) was performed in Linzhou, China, with endoscopic screening plus iodine staining. All the eligible histologically confirmed SD/CIS patients were followed up through the door-todoor follow-up and local cancer registry. The endpoint was diagnosed as ESCC or the December 31 st, 2016.Kaplan-Meier survival analysis and Log-rank test were used to compare the survival rates among treated and untreated patients.Results: A total of 175 SD/CIS patients were enrolled and grouped by whether they received endoscopic treatment. Eleven-year cumulative incidence rates for untreated and treated SD/CIS patients were 10.7% [95%confidence interval(95% CI): 6.9-16.1] and 3.2%(95% CI: 1.4-7.0), respectively. The ESCC incidence free survival rate, and all-cause incidence and mortality free survival rates were all significantly higher in the treated patients vs. untreated patients(P=0.043, P=0.008 and P=0.015, respectively). The ESCC mortality free survival rate showed no significant differences between the two groups(P=0.847).Conclusions: The cumulative incidence rate of SD/CIS patients to ESCC was much lower than previously reported. The Kaplan-Meier survival analysis showed that endoscopic treatment could increase the ESCC and allcause disease-free survival rates of SD/CIS patients significantly. | Meng Wang Changqing Hao Shuanghua Xie Shanrui Ma Qing Ma Rongshou Zheng Ru Chen Xinqing Li Wenqiang Wei | 2019 | Chinese Journal of Cancer Research2019，31，2： | 4 |
| 8 | Mesoscopic superelasticity,superplasticity,and superrigidity显示文摘Atomic-undercoordination-induced local bond contraction,bond strength gain,and the associated temperature (T)-dependent atomic-cohesive-energy and binding-energy-density are shown to originate intrinsically the exotic paradox of superplasticity,superelasticity,and superrigidity demonstrated by solid sizing from monatomic chain to mesoscopic grain.The paradox follows these relationships:(ε(K,T)y(K,T)σ(K,T))∝(exp(B/△T_(mk)),(η_1△T_(mk))d~(-3),[1+AK~(-2/2)exp(△T_(mk)/T)]△T_(mk)d~(-3)),(Plastic strain)(Elastic modulus)(Yield stress,IHPR)where A,B,η1,d and△T_(mk)=Tm(K) Tare size (K)-dependent physical parameters.Tm (K) is the melting point.Mechanical work hardening during compressing and self-heating during stretching modulate the measured outcome extrinsically.Superplasticity dominates in the solid-quasimolten-liquid transition state.The competition between the accumulation and annihilation of dislocations activates the inverse Hall-Petch relationship.Therefore,it is essential for one to discriminate the intrinsic competition between the local bond energy density gain and the atomic cohesive energy loss from the extrinsic factors of pressure and temperature in dealing with atomistic mechano-thermo dynamics. | MA ZengSheng ZHOU ZhaoFeng HUANG YongLi ZHOU YiChun SUN ChangQing | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，6： | 3 |
| 9 | A Facile Self-assembly Synthesis of Hexagonal ZnO Nanosheet Films and Their Photoelectrochemical Properties显示文摘Here, large-scale and uniform hexagonal zinc oxide(ZnO) nanosheet films were deposited onto indium tin oxide(ITO)-coated transparent conducting glass substrates via a facile galvanic displacement deposition process. Compared with other commonly used solution methods, this process avoids high temperature and electric power as well as supporting agents to make it simple and cost-effective. The as-fabricated ZnO nanosheet films have uniform hexagonal wurtzite structure. The photoelectrochemical(PEC) cell based on ZnO nanosheet film/ITO photoelectrode was also fabricated and its performance was improved by optimizing the solution concentration. A higher photocurrent density of*500 l A cm^(-2)under AM 1.5 G simulated illumination of 100 m W cm^(-2)with zero bias potential(vs. Ag/AgCl electrode) was obtained, which may ascribe to the increased surface-to-volume ratio of disordered Zn O nanosheet arrays. Our developed method may be used to deposit other oxide semiconductors, and the Zn O nanosheet film/ITO PEC cell can be used to design low-cost optoelectronic and photoelectrochemical devices. | Bin Zhang Faze Wang Changqing Zhu Qiang Li Jingnan Song Maojun Zheng Li Ma Wenzhong Shen | 2016 | Nano-Micro Letters2016，8，2： | 3 |
| 10 | Surface nanostructure formation mechanism of 45 steel induced by supersonic fine particles pombarding显示文摘By means of supersonic fine particles bombarding (SFPB),a nanostructured surface layer up to 15 μm was fabricated on a 45 steel plate with ferrite and pearlite phases. To reveal the grain refinement mechanism of SFPB-treated 45 steel,microstructure features of various sections in the treated surface were systematically characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Grain size increases with an increase of depth from the treated surface. Plastic deformation and grain refinement processes are accompanied by an increase in strain. Plastic deformation in the proeutectoid ferrite phases has precedence over the pearlite phases. Grain refinement in the ferrite phases involves: the onset of dis-location lines (Dls),dislocation tangles (DTs) and dense dislocation walls (DDWs) in the original grains; the formation of fine la-mellar and roughly equiaxed cells separated by DDWs; by dislocation annihilation and rearrangement,the transformation of DDWS into subboundaries and boundaries and the formation of submicron grains or subgrains; the successive subdivision of grains to finer and finer scale,resulting in the formation of highly misoriented nano-grains. By contrast,eutectoid cementite phase accommodated strain in a sequence as follows: onset of elongated,bended and shear deformation under deformation stress of ferrites,short and thin cementites with a width of about 20-50 nm and discontinuous length were formed. Shorter and thinner cementites were developed into ultra-fine pieces under the action of high density dislocation and strains. At the top surface,some cementites were decomposed under severe plastic deformation. Experimental evidences and analysis indicate that surface nanocrystallization of 45 steel results from dislocation activities,high strains and high strain rate are necessary for the formation of nanocrystallites. | Dema Ba Shining Ma Changqing Li Fanjun Meng | 2008 | Journal of University of Science and Technology Beijing2008，15，5： | 3 |
| 11 | Disruption of the bHLH transcription factor Abnormal Tapetum 1 causes male sterility in watermelon显示文摘Although male sterility has been identified as a useful trait for hybrid vigor utilization and hybrid seed production,its underlying molecular mechanisms in Cucurbitaceae species are still largely unclear.Here,a spontaneous male-sterile watermelon mutant,Se18,was reported to have abnormal tapetum development,which resulted in completely aborted pollen grains.Map-based cloning demonstrated that the causal gene Citrullus lanatus Abnormal Tapetum 1(ClATM1)encodes a basic helix-loop-helix(bHLH)transcription factor with a 10-bp deletion and produces a truncated protein without the bHLH interaction and functional(BIF)domain in Se18 plants.qRT–PCR and RNA in situ hybridization showed that ClATM1 is specifically expressed in the tapetum layer and in microsporocytes during stages 6–8a of anther development.The genetic function of ClATM1 in regulating anther development was verified by CRISPR/Cas9-mediated mutagenesis.Moreover,ClATM1 was significantly downregulated in the Se18 mutant,displaying a clear dose effect at the transcriptional level.Subsequent dual-luciferase reporter,β-glucuronidase(GUS)activity,and yeast one-hybrid assays indicated that ClATM1 could activate its own transcriptional expression through promoter binding.Collectively,ClATM1 is the first male sterility gene cloned from watermelon,and its self-regulatory activity provides new insights into the molecular mechanism underlying anther development in plants. | Ruimin Zhang Jingjing Chang Jiayue Li Guangpu Lan Changqing Xuan Hao Li Jianxiang Ma Yong Zhang Jianqiang Yang Shujuan Tian Li Yuan Xian Zhang Chunhua Wei | 2021 | Horticulture Research2021，8，1： | 3 |
| 12 | Effect of acupotomy on chondrocyte proliferation and expression of CyclinD1,CDK4 and CDK6 in rabbits with knee osteoarthritis显示文摘Objective:The aim of this study was to investigate the mechanism of acupotomology(Apo)in the prevention of articular cartilage destruction via the promotion of chondrocyte proliferation and chondrocyte expression of cell cycle regulators,CyclinD1,CDK4 and CDK6 in a rabbit knee osteoarthritis(KOA)model.Methods:Twenty-eight rabbits were randomly divided into a control group,an OA(osteoarthritis)model group,an Apo(acupotomology)group and EA(electro-acupuncture)group(n Z 7).Improved Videman’s method was used to induce a rabbit model of KOA over 6 weeks.One week later,acupotomy and electro-acupuncture therapy was applied to animals in the respective groups and treatment lasted 4 weeks.Following these treatments,quantitative real-time PCR,immunohistochemical staining and western blotting were performed to assess the mRNA and protein levels of cell cycle regulators CyclinD1(Cell cycle protein D1),CDK4(Cyclin-dependent kinase 4)and CDK6(Cyclin-dependent kinase 6).Ethology measures and knee morphology were also compared among groups.Results:The Lequesne MG index score of morphology was increased(P<.01),and the passive range of motion(PROM)and the mRNA and protein levels of CyclinD1,CDK4,and CDK6 were significantly decreased(P<.01)in the OA model compared with the control group.The Lequesne MG index score and the morphology score were decreased in the Apo and EA group compared with the OA model group(P<.05 or P<.01),while the mRNA levels of CyclinD1,CDK4,and CDK6,and the protein levels of CDK4 were increased in the Apo and EA groups compared with the OA model group(P<.05 or P<.01).The PROM,and the protein levels of CyclinD1 and CDK6 were increased(P<.05)in the Apo group compared with the OA model group,while the PROM and the protein levels of CyclinD1 and CDK6 in the EA group were not significantly different(P>.05).Compared with the EA group,the morphology score was decreased in Apo group(P<.05).Conclusions:The mRNA levels of CyclinD1 and CDK4,and the protein level of CDK4 in chondrocytes are regulate by both Apo and EA.Apo is more effective than EA in regulating the protein levels of CyclinD1 and CDK6.According to the observed changes in morphology and cytokine levels,acupotomy can promote chondrocyte proliferation and can alleviate the destruction of articular cartilage in a model of KOA. | Yang Gao Tong Wang Wei Zhang Xiaowei Shi Shining Ma Lijuan Wang Shuai Zhou Defeng Wang Meyer Magali Changqing Guo | 2019 | Journal of Traditional Chinese Medical Sciences2019，6，3： | 2 |

| 17 | MD-AVB: A Multi-Manifold Based Available Bandwidth Prediction Algorithm显示文摘The performance of Internet applications is heavily affected by the end-to-end available bandwidth. Thus,it is very important to examine how to accurately predict the available Internet bandwidth. A number of available bandwidth prediction algorithms have been proposed to date, but none of the existing solutions are able to achieve a high level of accuracy. In this paper, a Multi-manifold based Available Bandwidth prediction algorithm(MD-AVB)is proposed, based on the observation that the available bandwidth space on the Internet is multi-manifold and asymmetrical. In the proposed algorithm, the available bandwidth space is divided into multiple lower-dimensional domains iteratively, and each domain is embedded separately to predict the available bandwidth. Experiments on HP S^3 datasets demonstrate that the proposed algorithm is more accurate than existing approaches. | Pei Zhang Changqing An Zhanfeng Wang Fengyuan Ma | 2020 | Tsinghua Science and Technology2020，25，1： | 1 |

| 19 | Fast Growth of Highly Ordered TiO2 Nanotube Arrays on Si Substrate under High-Field Anodization显示文摘Highly ordered TiO_2 nanotube arrays(NTAs) on Si substrate possess broad applications due to its high surfaceto-volume ratio and novel functionalities, however, there are still some challenges on facile synthesis. Here, we report a simple and cost-effective high-field(90–180V) anodization method to grow highly ordered TiO_2 NTAs on Si substrate,and investigate the effect of anodization time, voltage, and fluoride content on the formation of TiO_2 NTAs. The current density–time curves, recorded during anodization processes, can be used to determine the optimum anodization time. It is found that the growth rate of TiO_2 NTAs is improved significantly under high field, which is nearly 8 times faster than that under low fields(40–60 V). The length and growth rate of the nanotubes are further increased with the increase of fluoride content in the electrolyte. | Jingnan Song Maojun Zheng Bin Zhang Qiang Li Faze Wang Liguo Ma Yanbo Li Changqing Zhu Li Ma Wenzhong Shen | 2017 | Nano-Micro Letters2017，9，2： | 1 |
