2Epigenetic regulation in B-cell maturation and its dysregulation in autoimmunity显示文摘B cells have a critical role in the initiation and acceleration of autoimmune diseases, especially those mediated byautoantibodies. In the peripheral lymphoid system, mature B cells are activated by self or/and foreign antigens andsignals from helper T cells for differentiating into either memory B cells or antibody-producing plasma cells.Accumulating evidence has shown that epigenetic regulations modulate somatic hypermutation and class switchDNA recombination during B-cell activation and differentiation. Any abnormalities in these complex regulatoryprocesses may contribute to aberrant antibody production, resulting in autoimmune pathogenesis such as systemiclupus erythematosus. Newly generated knowledge from advanced modern technologies such as next-generationsequencing, single-cell sequencing and DNA methylation sequencing has enabled us to better understand B-cellbiology and its role in autoimmune development. Thus this review aims to summarize current research progress inepigenetic modifications contributing to B-cell activation and differentiation, especially under autoimmuneconditions such as lupus, rheumatoid arthritis and type 1 diabetes.Haijing Wu Yaxiong Deng Yu Feng Di Long Kongyang Ma Xiaohui Wang Ming Zhao Liwei Lu Qianjin Lu 2018Cellular & Molecular Immunology2018,15,7:10
3Occurrence of mycotoxins in feed ingredients and complete feeds obtained from the Beijing region of China显示文摘Background:The current study was carried out to provide a reference for the control of mycotoxin contamination in feed ingredients and complete feeds for swine.Methods:A total of 55 feed ingredients,including 14 corn,13 wheat bran,11 soybean meal and 17 dried distillers grains with solubles(DDGS) as well as 76 complete swine feeds including 7 creep feeds,14 starter feeds,14 grower feeds,18 grower-finisher feeds,10 gestating sow feeds,and 13 lactating sow feeds were randomly collected from15 swine farms located in the Beijing region of China from July to August 2011.Immunoaffinity clean-up,using High-Performance Liquid Chromatography(HPLC) in combination with UV or Fluorescence Detection,was used for quantitative analysis of aflatoxin B,(AFB,),deoxynivalenol(DON),zearalenone(ZEA) and ochratoxin A(OTA) in the ingredients and complete feeds.Results:DON and ZEA were the most prevalent mycotoxins found.DON was detected at percentages of 93,92,54,100 and 97%with a mean level of 1.01,0.44,0.05,1.36 and 0.65 ppm in the samples of corn,wheat bran,soybean meal,DDGS and complete feeds,respectively.The detected percentages of ZEA were 100,100,54,100 and 100 with mean levels of 109.1,14.9,9.2,882.7 and 58.9 ppb in the same samples.In the wheat bran and soybean meal samples,the content of all four mycotoxins were below the maximum limits set by Chinese regulations while the percentage of samples that exceeded regulatory limits were 7,57 and 7%for corn,and 7,14 and 3%for the complete feeds for AFB,,DON and OTA respectively.DDGS showed the most serious mycotoxin contamination and the percentage of samples that exceeded regulatory limits were 6,88 and 41%,for AFB,,DON and ZEA,respectively.Conclusions:This paper is the first to present data on the natural occurrence of AFB,,DON,ZEA and OTA in ingredients and complete feeds obtained from swine farms in China's Beijing region.The data shows that feed ingredients and complete swine feeds obtained from these farms are most often contaminated with DON followed by contamination with AFB,and ZEA.Xiaoying Li Lihong Zhao Yu Fan Yaxiong Jia Lei Sun Shanshan Ma Cheng Ji Qiugang Ma Jianyun Zhang 2014Journal of Animal Science and Biotechnology2014,5,4:7
4Development and validation of a nomogram for predicting the survival of patients with non-metastatic nasopharyngeal carcinoma after curative treatment显示文摘Background: The TNM staging system is far from perfect in predicting the survival of individual cancer patients because only the gross anatomy is considered. The survival rates of the patients who have the same TNM stage disease vary across a wide spectrum. This study aimed to develop a nomogram that incorporates other clinicopathologic factors for predicting the overall survival(OS) of non-metastatic nasopharyngeal carcinoma(NPC) patients after curative treatments.Methods: We retrospectively collected the clinical data of 1520 NPC patients who were diagnosed histologically between November 2000 and September 2003. The clinical data of a separate cohort of 464 patients who received intensity-modulated radiation therapy(IMRT) between 2001 and 2010 were also retrieved to examine the extensibility of the model. Cox regression analysis was used to identify the prognostic factors for building the nomogram. The predictive accuracy and discriminative ability were measured using the concordance index(c-index).Results: We identiied and incorporated 12 independent clinical factors into the nomogram. The calibration curves showed that the prediction of OS was in good agreement with the actual observation in the internal validation set and IMRT cohort. The c-index of the nomogram was statistically higher than that of the 7th edition TNM staging system for predicting the survival in both the primary cohort(0.69 vs. 0.62) and the IMRT cohort(0.67 vs. 0.63).Conclusion: We developed and validated a novel nomogram that outperformed the TNM staging system in predicting the OS of non-metastatic NPC patients who underwent curative therapy.Wenhua Liang Guanzhu Shen Yaxiong Zhang Gang Chen Xuan Wu Yang Li Anchuan Li Shiyang Kang Xi Yuan Xue Hou Peiyu Huang Yan Huang Hongyun Zhao Ying Tian Chong Zhao Li Zhang 2016Chinese Journal of Cancer2016,35,12:6
5Carbon emission trading system of China: a linked market vs. separated markets显示文摘中国政府打算升级它在 2015 交换飞行员到一个全国性的计划的当前的省的碳排放。这研究调查二种情形:分开的省的市场和一个连接内部省的市场。分开并且连接的市场的碳消退效果基于一个可计算出来的一般平衡模型用湖北和广东的二个飞行员省被比较称为的 Sino-TERMCo2。模拟结果证明连接市场能与分开的市场相比为国家以及为湖北广东团体改进社会福利和还原剂碳排放紧张。然而,联合系统也更不均匀的散布福利并且因此增加社会不公正。在政策地面上,当前的结果建议与足够的福利转移政策补充的一个构造得好的、全国性的碳市场能被采用代替当前的自顶向下的消退目标崩溃实践。Yu LIU Shenghao FENG Songfeng Yaxiong ZHANG Xiang ZHOU Yanbin CHEN Zhanming CHEN 2013Frontiers of Earth Science2013,7,4:5
6Liensinine induces gallbladder cancer apoptosis and G2/M arrest by inhibiting ZFX-induced PI3K/AKT pathway显示文摘Gallbladder carcinoma (GBC) is the most comm on and aggressive can cer of the biliary tract. Liensinine has been proved to have hypotensive effect. However, the effect of liensinine on GBC is still unknown. The aim of this study is to investigate the effect and mechanism of liensinine in human GBC cells. Cell viability assay and colony formation assay were performed to assess cell growth and proliferation. Flow cytometry analysis was used to investigate cell cycle apoptosis in vitro. Hoechst 33342 staining was also used to evaluate cell apoptosis. Western blot analysis was used to determine the expression of proteins corresponding to the related cell cycle and apoptosis.The effect of liensinine treatment in vivo was experimented with xenografted tumors. We found that liensinine significantly inhibited the growth of GBC cells both in vivo and in vitro. In vitro, cell growth and proliferation were significantly suppressed by liensinine in a dose- and time-dependent manner. In vivo, liensinine inhibited tumor growth. Liensinine could induce GBC cells G2/M phase arrest by up-regulating the levels of Cyclin B1 and CDK1 proteins. Liensinine also affected GBC cell cycle progress!on and induced apoptosis by down-regulating phosphorylated protein kinase B (AKT), phosphorylated protein kinase B (p-AKT), phosphatidylinositol 3-kinase (PI3K), and Zinc finger X-chromosomal protein (ZFX) proteins. Liensinine induced G2/M arrest and apoptosis in gallbladder cancer, suggest!ng that liensinine might represent a novel and effective agent against gallbladder cancer.Yitong Shen Rui Bian Yaxiong Li Yuan Gao Yingbin Liu Yuzhen Xu Xiaoling Song Yijian Zhang 2019Acta Biochimica et Biophysica Sinica2019,51,6:4
7Identification and location of grapevine sucker based on information fusion of 2D laser scanner and machine vision显示文摘Chemical sucker control has been proven to be a more efficient method than manual and mechanical removals.The quick and effective identification and location of suckers are key technologies for targeted spray that can reduce chemical applications and alleviate potential problems.The goal of this research was to improve the accuracy of identification and location algorithm of grapevine suckers for real-time mobile targeted spray based on information fusion of two dimensional(2D)laser scanner and camera machine vision.A triangle white calibration board was used to determine the invisible laser scanning line.The positions of the terminated points of the scanning line on the calibration board in the laser scanner’s coordinates were calculated.Suckers size and center location were obtained by ExGExR segmentation,then the relative position between the suckers and triangle calibration board was determined in the image coordinates.Eventually,the actual size and relative position between the identified suckers and the platform were calculated by integrating the laser line and image information.The results of the field trials showed that the consumed time of the developed algorithm was 0.787 s,the width recognition rate 91.8%,height recognition rate 88.2%,and the relative position accuracies 92.0%,87.3%,which could meet the requirement of grapevine sucker precision targeted spray.Wang Yaxiong Xu Shasha Li Wenbin Kang Feng Zheng Yongjun 2017International Journal of Agricultural and Biological Engineering2017,10,2:4
8A graphene rheostat for highly durable and stretchable strain sensor显示文摘Strain sensors for human health monitoring are of paramount importance in wearable medical diagnostics and personal health monitoring.Despite extensive studies,strain sensors with both high durability and stretchability are still desired,particularly with the stability for different environmental conditions.Here,we report a series of strain sensors possessing the graphene network with a high density of intermittent physical interconnections,which produces the relative resistance change by varying the overlap area between the neighboring graphene sheets under stretching and releasing,analogous to the slide rheostat working in electronics.Our in-situ transmission electron microscope observation reveals the full recoverability of the structure from large deformation upon unloading for ensuring the exceptional cycle stability of our material on monitoring full-range body movements.The stable response is also demonstrated over wide temperature range and frequency range,because the peculiar dynamic structure can be maintained through the self-adjustment to the thermal expansion of the bulk material.Based on the working mechanism of graphene“slide rheostat,”the sensing properties of the strain sensor are tailored by tuning the graphene network structure with different mass densities using different concentrations of graphene oxide dispersion,while the stretchability and sensitivity can be separately optimized for different application requirements.Jing Ren Wenjun Zhang Yubo Wang Yaxiong Wang Jun Zhou Liming Dai Ming Xu 2019InfoMat2019,1,3:4
9Dache: A Data Aware Caching for Big-Data Applications Using the MapReduce Framework显示文摘The buzz-word big-data refers to the large-scale distributed data processing applications that operate on exceptionally large amounts of data. Google's MapReduce and Apache's Hadoop, its open-source implementation, are the defacto software systems for big-data applications. An observation of the MapReduce framework is that the framework generates a large amount of intermediate data. Such abundant information is thrown away after the tasks finish, because MapReduce is unable to utilize them. In this paper, we propose Dache, a data-aware cache framework for big-data applications. In Dache, tasks submit their intermediate results to the cache manager. A task queries the cache manager before executing the actual computing work. A novel cache description scheme and a cache request and reply protocol are designed. We implement Dache by extending Hadoop. Testbed experiment results demonstrate that Dache significantly improves the completion time of MapReduce jobs.Yaxiong Zhao Jie Wu Cong Liu 2014Tsinghua Science and Technology2014,19,1:3

13Photodynamic therapy accelerates skin wound healing through promoting re-epithelialization显示文摘Background:Epidermal stem cells(EpSCs)that reside in cutaneous hair follicles and the basal layer of the epidermis are indispensable for wound healing and skin homeostasis.Little is known about the effects of photochemical activation on EpSC differentiation,proliferation and migration during wound healing.The present study aimed to determine the effects of photodynamic therapy(PDT)on wound healing in vivo and in vitro.Methods:We created mouse full-thickness skin resection models and applied 5-aminolevulinic acid(ALA)for PDT to the wound beds.Wound healing was analysed by gross evaluation and haematoxylin–eosin staining in vivo.In cultured EpSCs,protein expression was measured using flow cytometry and immunohistochemistry.Cell migration was examined using a scratch model;apoptosis and differentiation were measured using flow cytometry.Results:PDT accelerated wound closure by enhancing EpSC differentiation,proliferation and migration,thereby promoting re-epithelialization and angiogenesis.PDT inhibited inflammatory infiltration and expression of proinflammatory cytokines,whereas the secretion of growth factors was greater than in other groups.The proportion of transient amplifying cells was significantly greater in vivo and in vitro in the PDT groups.EpSC migration was markedly enhanced after ALAinduced PDT.Conclusions:Topical ALA-induced PDT stimulates wound healing by enhancing re-epithelialization,promoting angiogenesis as well as modulating skin homeostasis.This work provides a preliminary theoretical foundation for the clinical administration of topical ALA-induced PDT in skin wound healing.Zengjun Yang Xiaohong Hu Lina Zhou Yaxiong He Xiaorong Zhang Jiacai Yang Zhenyu Ju Yih-Cherng Liou Han-Ming Shen Gaoxing Luo Michael R.Hamblin Weifeng He Rui Yin 2021Burns & Trauma2021,9,1:3
14A novel lignite pre-drying system with low-grade heat integration for modern lignite power plants显示文摘The lignite pre-drying process plays an important role in modern lignite power plants and the fluidized bed dryer with internal heat utilization is a promising drying method which has both high efficiency and cost-effectiveness. After conducting an in-depth analysis of a typical lignite pre-drying power plant, this work proposed a novel lignite pre-drying system with low-grade heat integration. Through system integration, the low-temperature evaporation of the lignite was recovered to heat the combustion air, while the residual heat from the flue gases was used to heat the feed or condensed water, thereby saving a portion of heat from the steam bleeds of the high and intermediate pressure turbines. The results for a1,000 MW lignite-fired power plant showed that, the proposed pre-drying system could yield an increase in net plant efficiency of approximately 3.6 % points and a reduction in the cost of electricity of $1.83/(MW h). The thermodynamic and economic performances were each superior to those of the existing pre-drying system, convincingly demonstrating that the research of this paper may provide a promising integrated lignite pre-drying method for the next-generation of lignite-fired power plants.Cheng Xu Gang Xu Yu Han Feifei Liang Yaxiong Fang Yongping Yang 2014Chinese Science Bulletin2014,59,33:2

16On Peer-Assisted Data Dissemination in Data Center Networks: Analysis and Implementation显示文摘Data Center Networks(DCNs) are the fundamental infrastructure for cloud computing. Driven by the massive parallel computing tasks in cloud computing, one-to-many data dissemination becomes one of the most important traffic patterns in DCNs. Many architectures and protocols are proposed to meet this demand. However, these proposals either require complicated configurations on switches and servers, or cannot deliver an optimal performance. In this paper, we propose the peer-assisted data dissemination for DCNs. This approach utilizes the rich physical connections with high bandwidths and mutli-path connections, to facilitate efficient one-to-many data dissemination. We prove that an optimal P2P data dissemination schedule exists for FatTree, a speciallydesigned DCN architecture. We then present a theoretical analysis of this algorithm in the general multi-rooted tree topology, a widely-used DCN architecture. Additionally, we explore the performance of an intuitive line structure for data dissemination. Our analysis and experimental results prove that this simple structure is able to produce a comparable performance to the optimal algorithm. Since DCN applications heavily rely on virtualization to achieve optimal resource sharing, we present a general implementation method for the proposed algorithms, which aims to mitigate the impact of the potentially-high churn rate of the virtual machines.Yaxiong Zhao Jie Wu Cong Liu 2014Tsinghua Science and Technology2014,19,1:2
17Transferrin plays a central role in coagulation balance by interacting with clotting factors显示文摘Coagulation balance is maintained through fine-tuned interactions among clotting factors,whose physiological concentrations vary substantially.In particular,the concentrations of coagulation proteases(pM to nM)are much lower than their natural inactivator antithrombin(AT,〜3μM),suggesting the existence of other coordinators.In the current study,we found that transferrin(norm plasma concentration〜40 μM)interacts with fibrinogen,thrombin,factor Xlla(FXlla),and AT with different affinity to maintain coagulation balance.Normally,transferrin is sequestered by binding with fibrinogen(normal plasma concentration〜10 μM)at a molar ratio of 4:1.In atherosclerosis,abnormally up-regulated transferrin interacts with and potentiates thrombin/FXlla and blocks ATs inactivation effect on coagulation proteases by binding to AT,thus inducing hypercoagulability.In the mouse model,transferrin overexpression aggravated atherosclerosis,whereas transferrin inhibition via shRNA knockdown or treatment with antitransferrin antibody or designed peptides interfering with transferrin-thrombin/FXlla interactions alleviated atherosclerosis.Collectively,these findings identify that transferrin is an important clotting regulator and an adjuster in the maintenance of coagulation balance and modifies the coagulation cascade.Xiaopeng Tang Zhiye Zhang Mingqian Fang Yajun Han Gan Wang Sheng Wang Min Xue Yaxiong Li Li Zhang Jian Wu Biqing Yang James Mwangi Qiumin Lu Xiaoping Du Ren Lai 2020Cell Research2020,30,2:2
18Novel human H7N9 influenza virus in China显示文摘Outbreaks of H7N9 avian influenza in humans in 5 provinces and 2 municipalities of China have reawakened concern that avian influenza viruses may again cross species barriers to infect the human population and thereby initiate a new influenza pandemic.Evolutionary analysis shows that human H7N9 influenza viruses originated from the H9N2,H7N3 and H11N9 avian viruses,and that it is as a novel reassortment influenza virus.This ar­ticle reviews current knowledge on 11 subtypes of influenza A virus from human which can cause human infec­tions.Chengmin WANG Jing LUO Jing WANG Wen SU Shanshan GAO Min ZHANG Li XIE Hua DING Shelan LIU Xiaodong LIU Yu CHEN Yaxiong JIA Hongxuan HE 2014Integrative Zoology2014,9,3:2
19Effect of pore size on CH4/N2 separation using activated carbon显示文摘In this paper,a model of activated carbon was established by molecular simulation and the separation performance of N2 and CH4 on activated carbon was studied.In order to evaluate the adsorption selectivity and diffusion selectivity of N2 and CH4,Grand Canonical Monte Carlo and molecular dynamic methods were used to obtain equilibrium adsorption isotherms and mean square displacements of N2 and CH4 on activated carbon with different pore sizes.Research results showed that the difference in adsorption isosteric heat of N2 and CH4 at the pore size of 0.46 nm is the largest,which is 5.759 and 7.03 kcal·mol^-1(1 cal=4.184 J),respectively.Activated carbon with pore size of 0.46 nm has the best N2 and CH4 adsorption selectivity,while its diffusion selectivity is not obvious.Gaofei Chen Yaxiong An Yuanhui Shen Yayan Wang Zhongli Tang Bo Lu Donghui Zhang 2020Chinese Journal of Chemical Engineering2020,28,4:2
