| 1 | Features of colorectal cancer in China stratified by anatomic sites:A hospital-based study conducted in university-affiliated hospitals from 2014 to 2018显示文摘Objective:The clinical and biological characteristics of colorectal cancer have been found to differ depending on the anatomic site of the cancer.However,for Chinese patients,there is limited information on the proportion of cases at each site and the related features.In this study,we explored the location,distribution and other features of colorectal cancers at each anatomic site in Chinese patients.Methods:We conducted a hospital-based study using hospitalization summary reports from 10 Peking University-affiliated hospitals from 2014 to 2018;the reports covered a total of 2,097,347 hospitalizations.Incident cases were chosen as the study population,and their epidemiological features were further analyzed.Results:A total of 20,739 colorectal cancer patients were identified.Rectum was the most common location(48.3%)of the cancer,whereas the proportions of patients with distal and proximal colon cancer were 24.5%and18.6%,respectively.Patients with rectal cancer were predominantly male and were the youngest for all anatomical sites(each P<0.001).The highest proportion of emergency admissions,the longest hospital stays and the highest hospitalization costs were found in patients with proximal colon cancer(each P<0.001).The proximal colon cancer subgroup included the highest proportions of patients with medical histories of cholecystectomy,cholecystolithiasis and/or gallbladder polyps and appendectomy(P=0.009,P<0.001 and P<0.001,respectively).The distal colon cancer subgroup included the highest proportions of patients with medical histories of diabetes and hypertension(P<0.001,respectively).Conclusions:The patterns of colorectal cancer observed in this study differ from those reported for Western patients and show a significantly higher proportion of patients with rectal cancer.Different epidemiological features were also found based on anatomic sites.Further studies based on tumor location should be conducted to facilitate more accurate screening and treatment. | Ruize Qu Yanpeng Ma Liyuan Tao Xiaoyuan Bao Xin Zhou Bingyan Wang Fei Li Siyi Lu Lin Tuo Siyan Zhan Zhipeng Zhang Wei Fu | 2021 | Chinese Journal of Cancer Research2021，33，4： | 10 |
| 2 | WheatOmics:A platform combining multiple omics data to accelerate functional genomics studies in wheat显示文摘Dear Editor,Mold-breaking progress in whole-genome sequencing and rapid accumulation of multi-omics data have revolutionized the research strategies of functional genomics in wheat(Wang et al.,2018).However,how to access these vast multi-omics data and to extract key information on genes of in-terest,is still challenging for most wet-lab or field wheat re-searchers who have little bioinformatic experiences and cannot access the expensive computational resources.Here,we pre-sent WheatOmics(http://wheatomics.sdau.edu.cn/,previously designated as Triticeae Multi-omics Center,http://202.194.139.32/),a free,web-accessible,and user-friendly platform.WheatOmics not only empowers the effective access to the visualized multi-omics data of user-interested genes but also offers several distinctive and practical toolkits that can ease almost every aspect of wheat functional genomics studies(Figure 1A). | Shengwei Ma Meng Wang Jianhui Wu Weilong Guo Yongming Chen Guangwei Li Yanpeng Wang Weiming Shi Guangmin Xia Daolin FU Zhensheng Kang Fei Ni | 2021 | Molecular Plant2021，14，12： | 9 |
| 3 | Genomic insights into the fast growth of paulownias and the formation of Paulownia witches' broom显示文摘Paulownias are among the fastest growing trees in the world,but they often suffer tremendous loss of wood production due to infection by Paulownia witches'broom(PaWB)phytoplasmas.In this study,we have sequenced and assembled a high-quality nuclear genome of Paulownia fortunei,a commonly cultivated paulownia species.The assembled genome of P.fortunei is 511.6 Mb in size,with 93.2%of its sequences anchored to 20 pseudo-chromosomes,and it contains 31985 protein-coding genes.Phylogenomic analyses show that the family Paulowniaceae is sister to a clade composed of Phrymaceae and Orobanchaceae.Higher photosynthetic efficiency is achieved by integrating C3 photosynthesis and the crassulacean acid metabolism pathway,which may contribute to the extremely fast growth habit of paulownia trees.Comparative transcriptome analyses reveal modules related to cambial growth and development,photosynthesis,and defense responses.Additional genome sequencing of PaWB phytoplasma,combined with functional analyses,indicates that the effector PaWB-SAP54 interacts directly with Paulownia PfSPLa,which in turn causes the degradation of PfSPLa by the ubiquitin-mediated pathway and leads to the formation of witches'broom.Taken together,these results provide significant insights into the biology of paulownias and the regulatory mechanism for the formation of PaWB. | Yabing Cao Guiling Sun Xiaoqiao Zhai Pingluo Xu Liming Ma Minjie Deng Zhenli Zhao Haibo Yang Yanpeng Dong Zhonghai Shang Yujie Lv Lijun Yan Haifang Liu Xibing Cao Bingbing Li Zhe Wang Xiaogai Zhao Haiyan Yu Fan Wang Wen Ma Jinling Huang Guoqiang Fan | 2021 | Molecular Plant2021，14，10： | 7 |

| 6 | The Seismogenic Structure of the 2010 Suining Ms 5.0 Earthquake and its Geometry,Kinematics and Dynamics Analysis显示文摘在 2010 年 1 月, Suining Ms5.0 地震发生在中央四川盆,与在 Moxi-Longnvsi 结构的带和 10 km 的焦点的深度的震中。在这个区域基于地震侧面的结构的解释,我们认出了在 910 km 的深度位于 Suining 区域的 Presinian 地下室的一个地区性的分开差错,转移它从 NW 滑倒到 SE 取向。从 NW 滑动到 SE,并且经历了几的这个分开差错砍并且弯曲,它引起了地下室被卷在并且覆盖阶层褶层变丑。它在 Moxi 区域形成了差错拐弯褶层与一近似 4 km 滑倒。相应地, Moxi 背斜的形成与分开差错有关。与地震分开差错的斜面上的震中,有一个新观点, Suining 地震被这个地下室分开差错的复活引起。自从迟了的侏罗记时期,在地区性的构造应力的影响下面,分开差错从 Longmen 山( LMS )戳带把它的slip 转移了到四川盆的内地,并且最后到西南 Huayingshan ( HYS )的山麓地区,它显示 HYS 可能是 LMS 戳带的最后的前面区域。 | LU Renqi HE Dengfa JOHN Suppe MA Yongsheng GUAN Shuwei SUN Yanpeng GAO Jinwei | 2011 | Acta Geologica Sinica(English Edition)2011，85，6： | 5 |
| 7 | Clusterin in Alzheimer's disease: a player in the biological behavior of amyloid-beta显示文摘Alzheimer's disease (AD) remains a major killer, and although its pathogenesis varies, one dominant feature is an increase in the expression, formation, and sedimentation of senile plaques of amyloid-beta (Aβ) peptides in the brain. The chaperone protein clusterin has, since its first discovery at the end of the 20th century, been labeled as a cytoprotector. However, epigenetic studies showing that clusterin is associated with the severity and risk of AD, especially in the hippocampus, triggered studies to clarify its role in the pathogenesis of AD. It is true that clusterin can inhibit the aggregation of Aβ and therefore prevent further formation of senile plaques in the AD brain, yet it induces the formation of soluble forms of Aβ which are toxic to neurons. Another problematic finding is that clusterin is involved in a pathway through which Aβ has neurodegenerative effects intracellularly. Although the role of clusterin in the pathogenesis of AD is still not clear, this review specifically discusses the interactions between clusterin and Aβ, to open up the possibility of a potential therapeutic approach for treating AD. | Xiang Li Yifei Ma Xu Wei Yanpeng Li Huijuan Wu Jianhua Zhuang Zhongxin Zhao | 2014 | Neuroscience Bulletin2014，30，1： | 4 |
| 8 | Kinetics of Solvent Blue and Reactive Yellow removal using microwave radiation in combination with nanoscale zero-valent iron显示文摘We investigated the efficiency and kinetics of the degradation of soluble dyes over the p H range 5.0–9.0 using a method employing microwave radiation in combination with nanoscale zero-valent iron(MW–n ZVI). The n ZVI particles(40–70 nm in diameter) were prepared by a liquid-phase chemical reduction method employing starch as a dispersant.Compared to the removal of Solvent Blue 36 and Reactive Yellow K-RN using only n ZVI,more rapid and efficient dye removal and total organic carbon removal were achieved using MW–n ZVI. The dye removal efficiency increased significantly with decreasing p H, but was negligibly affected by variation in the microwave power. The kinetics of dye removal by MW–n ZVI followed both an empirical equation and the pseudo first-order model, while the kinetics of dye removal using n ZVI could only be described by an empirical equation. It was also concluded that microwave heating of the dye solutions as well as acceleration of corrosion of n ZVI and consumption of Fe(II) were possible reasons behind the enhanced dye degradation. | Yanpeng Mao Zhenqian Xi Wenlong Wang Chunyuan Ma Qinyan Yue | 2015 | Journal of Environmental Sciences2015，27，4： | 3 |
| 9 | The source and transport of bioaerosols in the air:A review显示文摘Recent pandemic outbreak of the corona-virus disease 2019(COVID-19)has raised widespread concerns about the importance of the bioaerosols.They are atmospheric aerosol particles of biological origins,mainly including bacteria,fungi,viruses,pollen,and cell debris.Bioaerosols can exert a substantial impact on ecosystems,climate change,air quality,and public health.Here,we review several relevant topics on bioaerosols,including sampling and detection techniques,characterization,effects on health and air quality,and control methods.However,very few studies have focused on the source apportionment and transport of bioaerosols.The knowledge of the sources and transport pathways of bioaerosols is essential for a comprehensive understanding of the role microorganisms play in the atmosphere and control the spread of epidemic diseases associated with them.Therefore,this review comprehensively summarizes the up to date progress on the source characteristics,source identification,and diffusion and transport process of bioaerosols.We intercompare three types of diffusion and transport models,with a special emphasis on a widely used mathematical model.This review also highlights the main factors affecting the source emission and transport process,such as biogeographic regions,land-use types,and environmental factors.Finally,this review outlines future perspectives on bioaerosols. | Wenwen Xie Yanpeng Li Wenyan Bai Junli Hou Tianfeng Ma Xuelin Zeng Liyuan Zhang Taicheng An | 2021 | Frontiers of Environmental Science & Engineering2021，15，3： | 2 |
| 10 | Altered vaginal eukaryotic virome is associated with different cervical disease status显示文摘Viruses are important components of the human body.Growing evidence suggests that they are engaged in the physiology and disease status of the host.Even though the vaginal microbiome is involved in human papillomavirus(HPV)infection and cervical cancer(CC)progression,little is known about the role of the vaginal virome.In this pilot exploratory study,using unbiased viral metagenomics,we aim to investigate the vaginal eukaryotic virome in women with different levels of cervical lesions,and examine their associations with different cervical disease status.An altered eukaryotic virome was observed in women with different levels of lesions and Lactobacillus profiles.Anelloviruses and papillomaviruses are the most commonly detected eukaryotic viruses of the vaginal virome.Higher abundance and richness of anelloviruses and papillomaviruses were associated with lowgrade squamous intraepithelial lesion(LSIL)and CC.Besides,higher anellovirus abundance was also associated with lactobacillus-depleted microbiome profiles and bacterial community state(CST)type IV.Furthermore,increased correlations between Anelloviridae and Papillomaviridae occurred in the women with increased cervical disease severity level from LSIL to CC.These data suggest underlying interactions between different microbes as well as the host physiology.Higher abundance and diversity of both anelloviruses and papillomaviruses shared by LSIL and CC suggest that anellovirus may be used as a potential adjunct biomarker to predict the risk of HPV persistent infection and/or CC.Future studies need to focus on the clinical relevance of anellovirus abundance with cervical disease status,and the evaluation of their potential as a new adjunct biomarker for the prediction and prognoses of CC. | Yanpeng Li Le Cao Xiao Han Yingying Ma Yanmei Liu Shujun Gao Chiyu Zhang | 2023 | Virologica Sinica2023，38，2： | 0 |
| 11 | Stimulus-responsive water soluble synthetic nanographene显示文摘Nanographenes(NGs)are exceptionally hydrophobic.They are insoluble in water,preventing the exploration and utilization of their photophysical properties under aqueous conditions.This work discloses an atomically precise water-soluble synthetic NG1,featuring a 2 nm sp^(2) carbon skeleton appended with 12 branched triethylene glycol chains.It synergistically combines low critical solution temperature(LCST)behavior and a photothermal effect to create the first thermo-and photo-responsive atomically precise NG functioning in an aqueous solution.The LCST behavior can be attributed to a delicate balance of hydrophobic-hydrophilic interactions,providing a sensitive thermal response to changes over a temperature range of physiological interest(close to 37℃).Moreover,1 has considerable photothermal conversion capability,with irradiation of 1 in water by red or near infrared light increasing the solutions temperature to above the clouding point within seconds,leading to a reversible clear-to-turbid transition over many cycles without evident fatigue. | Shuang Ma Yanpeng Zhu Weitao Dou Ying Chen Xiaopeng He Jiaobing Wang | 2021 | Science China Chemistry2021，64，4： | 0 |
| 12 | Heat treatment effects on the superconducting properties of Ag-doped SrKFeAs compounds显示文摘The superconducting properties of polycrystalline Sr0.6K0.4Fe2As2 were strongly influenced by Ag doping(Supercond.Sci.Technol.23(2010) 025027).Ag addition is mainly dominated by silver diffusing,so the annealing process is one of the essential factors to achieve high quality Ag doped Sr0.6K0.4Fe2As2.In this paper,the optimal annealing conditions were studied for Ag doped Sr0.6K0.4Fe2As2 bulks prepared by a one-step solid reaction method.It is found that the annealing temperature has a strong influence on the superconducting properties,especially on the critical current density Jc.As a result,higher heat treatment temperature(~900℃) is helpful in diffusing Ag and reducing the impurity phase gathered together to improve the grain connectivity.In contrast,low-temperature sintering is counterproductive for Ag doped samples.These results clearly suggest that annealing at ~900℃ is necessary for obtaining high Jc Ag-doped samples. | ZHANG ZhiYu,WANG Lei,QI YanPeng,GAO ZhaoShun,WANG DongLiang,ZHANG XianPing & MA YanWei* Key Laboratory of Applied Superconductivity,Institute of Electrical Engineering,Chinese Academy of Sciences,Beijing 100190,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，7： | 0 |
| 13 | Tectonic implications of the subduction of the Kyushu-Palau Ridge beneath the Kyushu,southwest Japan显示文摘The Kyushu-Palau Ridge(KPR),a remnant arc on the Philippine Sea Plate(PSP),is subducting beneath the Kyushu,southwest Japan.Influenced by the subducting KPR,the Kyushu subduction zone corresponding to the KPR is significantly different from Shikoku subduction zone in terms of gravity anomalies,seismicity,the stress state,and the subducting slab morphology.Significant negative free-air and Bouguer gravity anomalies are observed in a prolonged area of KPR,southeast of the Miyazaki Plain,indicating that this is where KPR overlaps the overriding plate.The gravity anomaly in this area is much lower than that in other areas where the inferred KPR extends,suggesting that the subduction of the buoyant KPR may cause the lower mantle density to decrease.More earthquakes have occurred in Hyuga-nada region where the KPR subducts than in Shikoku forearc and other areas in the Kyushu forearc,indicating that the subduction of the KPR enhances the local coupling between the subducting and overriding plates.The centroid moment tensor(CMT)mechanism of earthquakes shows that stress is concentrated in the accumulated crust beneath the Kyushu forearc corresponding to the KPR,and the shallow thrusting events in the obducting plate are caused by the KPR subduction.The buoyant KPR,with a large volume of low-density sediments,was responsible for the differences of the subduction depth and dip angle of the subducting Philippine Sea(PS)slab between northern Kyushu and Shikoku.The seismic gaps and the sudden change of the dipping angle of the subducting PS slab indicate that slab tear may have occurred along the west side of the KPR beneath southwest Kyushu.A two-tear model was proposed,and the subduction of the buoyant KPR was believed to play an important role in the slab tear. | Chenglong Xia Yanpeng Zheng Baohua Liu Qingfeng Hua Long Ma Xianfeng Li Qiuhong Xie | 2021 | Acta Oceanologica Sinica2021，40，3： | 0 |
| 14 | LSM12 facilitates the progression of colorectal cancer by activating the WNT/CTNNB1 signaling pathway显示文摘Aberrant activation of the WNT signaling pathway is a joint event in colorectal cancer(CRC),but the molecular mechanism is still unclear.Recently,RNA-splicing factor LSM12(like-Sm protein 12)is highly expressed in CRC tissues.This study aimed to verify whether LSM12 is involved in regulating CRC progression via regulating the WNT signaling pathway.Here,we found that LSM12 is highly expressed in CRC patient-derived tissues and cells.LSM12 is involved in the proliferation,invasion,and apoptosis of CRC cells,similar to the function of WNT signaling in CRC.Furthermore,protein interaction simulation and biochemical experiments proved that LSM12 directly binds to CTNNB1(also known asβ-Catenin)and regulates its protein stability to affect the CTTNB1-LEF1-TCF1 transcriptional complex formation and the associated WNT downstream signaling pathway.LSM12 depletion in CRC cells decreased the in vivo tumor growth through repression of cancer cell growth and acceleration of cancer cell apoptosis.Taken together,we suggest that the high expression of LSM12 is a novel factor leading to aberrant WNT signaling activation,and that strategies targeting this molecular mechanism may contribute to developing a new therapeutic method for CRC. | YAN ZHUANG CHUNLAN NING PENGFEI LIU YANPENG ZHAO YUE LI ZHENCHI MA LULING SHAN YINGZHE PIAO PENG ZHAO XUN JIN | 2022 | Oncology Research2022，30，6： | 0 |
| 15 | Interactions of Microplastics and Methane Seepage in the Deep-Sea Environment显示文摘Microplastics(MPs)are important exempla of the Anthropocene and are exerting an increasing impact on Earth’s carbon cycle.The huge imbalance between the MPs floating on the marine surface and those that are estimated to have been introduced into the ocean necessitates a detailed assessment of marine MP sinks.Here,we demonstrate that cold seep sediments,which are characterized by methane fluid seepage and a chemosynthetic ecosystem,effectively capture and accommodate small-scale(<100μm)MPs,with 16 types of MPs being detected.The abundance of MPs in the surface of the sediment is higher in methane-seepage locations than in non-seepage areas.Methane seepage is beneficial to the accumulation,fragmentation,increased diversity,and aging of MPs.In turn,the rough surfaces of MPs contribute to the sequestration of the electron acceptor ferric oxide,which is associated with the anaerobic oxidation of methane(AOM).The efficiency of the AOM determines whether the seeping methane(which has a greenhouse effect 83 times greater than that of CO_(2)over a 20-year period)can enter the atmosphere,which is important to the global methane cycle,since the deep-sea environment is regarded as the largest methane reservoir associated with natural gas hydrates. | Jing-Chun Feng Zhifeng Yang Wenliang Zhou Xingwei Feng Fuwen Wei Bo Li Chuanxin Ma Si Zhang Linlin Xia Yanpeng Cai Yi Wang | 2023 | Engineering2023，，10： | 0 |
| 16 | Competing esterification and oligomerization reactions of typical long-chain alcohols to secondary organic aerosol formation显示文摘Organosulfate (OSA) nanoparticles,as secondary organic aerosol (SOA) compositions,are ubiquitous in urban and rural environments.Hence,we systemically investigated the mechanisms and kinetics of aqueous-phase reactions of 1-butanol/1-decanol (BOL/DOL) and their roles in the formation of OSA nanoparticles by using quantum chemical and kinetic calculations.The mechanism results show that the aqueous-phase reactions of BOL/DOL start from initial protonation at alcoholic OH^(-)groups to form carbenium ions (CBs),which engage in the subsequent esterification or oligomerization reactions to form OSAs/organosulfites (OSIs) or dimers.The kinetic results reveal that dehydration to form CBs for BOL and DOL reaction systems is the rate-limiting step.Subsequently,about 18%of CBs occur via oligomerization to dimers,which are difficult to further oligomerize because all reactive sites are occupied.The rate constant of BOL reaction system is one order of magnitude larger than that of DOL reaction system,implying that relative short-chain alcohols are more prone to contribute OSAs/OSIs than long-chain alcohols.Our results reveal that typical long-chain alcohols contribute SOA formation via esterification rather than oligomerization because OSA/OSI produced by esterification engages in nanoparticle growth through enhancing hygroscopicity. | Jiaxin Wang Xiaohui Ma Yuemeng Ji Yongpeng Ji Yanpeng Gao Yuqi Xiao Guiying Li Taicheng An | 2023 | Journal of Environmental Sciences2023，，4： | 0 |
| 17 | Delineation of Integrated Anomaly with Generative Adversarial Networks and Deep Neural Networks in the Zhaojikou Pb-Zn Ore District,Southeast China显示文摘Geochemical maps are of great value in mineral exploration.Integrated geochemical anomaly maps provide comprehensive information about mapping assemblages of element concentrations to possible types of mineralization/ore,but vary depending on expert's knowledge and experience.This paper aims to test the capability of deep neural networks to delineate integrated anomaly based on a case study of the Zhaojikou Pb-Zn deposit,Southeast China.Three hundred fifty two samples were collected,and each sample consisted of 26 variables covering elemental composition,geological,and tectonic information.At first,generative adversarial networks were adopted for data augmentation.Then,DNN was trained on sets of synthetic and real data to identify an integrated anomaly.Finally,the results of DNN analyses were visualized in probability maps and compared with traditional anomaly maps to check its performance.Results showed that the average accuracy of the validation set was 94.76%.The probability maps showed that newly-identified integrated anomalous areas had a probability of above 75%in the northeast zones.It also showed that DNN models that used big data not only successfully recognized the anomalous areas identified on traditional geochemical element maps,but also discovered new anomalous areas,not picked up by the elemental anomaly maps previously. | DUAN Jilin LIU Yanpeng ZHU Lixin MA Shengming GONG Qiuli Alla DOLGOPOLOVA Simone A.LUDWIG | 2023 | Acta Geologica Sinica(English Edition)2023，97，4： | 0 |
| 18 | Comparison on Chromosome Number among Ussuri Raccoon Dogs with Three Different Coat Colors显示文摘[Objective]This study aimed to lay theoretical foundation for establishing the database of biological characteristics of raccoon dogs with different coat colors.[Method]Reddish-brown ussuri raccoon dogs,wild ussuri raccoon dogs and Jilin white raccoon dogs were used as experimental materials in this study.Chromosome specimens were prepared by peripheral blood lymphocyte culture,to analyze chromosome number of ussuri raccoon dogs with different coat colors.[Result]Frequencies of cells with diploid chromosome number of 56 in reddish-brown ussuri raccoon dogs and wild ussuri raccoon dogs were 86%and 83%respectively,indicating that the chromosome number of reddish-brown ussuri raccoon dogs and wild ussuri raccoon dogs was 56.The frequency of cells with diploid chromosome number of 56 in Jilin white raccoon dogs was 70%,which was lower than that of other two varieties,while the frequency of cells with 2n=57 was higher than that of other two varieties.[Conclusion]The chromosome number was 56 for reddish-brown ussuri raccoon dogs and wild ussuri raccoon dogs,and it was56 or 57 for Jilin white raccoon dogs,which represented polymorphism. | Yanpeng LI Zefang MA Yanfei ZHU Jinhai SUN | 2013 | Agricultural Biotechnology2013，2，6： | 0 |
