| 1 | Evolution of planetary boundary layer under different weather conditions,and its impact on aerosol concentrations显示文摘一个领域实验在天津被进行,从 2010 年 9 月 930 日的中国,在表面空气污染物质上集中了于行星的边界层(PBL ) 和它的影响的进化。实验使用了三台遥感仪器,风侧面雷达( WPR ),微波辐射计( MWR )和微脉搏的激光雷达( MPL ),到检测风,温度,和喷雾器 backscattering 系数并且到的垂直侧面测量表面污染物质的垂直侧面(喷雾器,公司, SO2 , NOx ),并且也从 255-m 收集了声音的风速表数据气象学的塔。把大小基于这些, PBL 的进化被估计。平均 PBL 高度在夜间期间在 noon/afternoon-time,和 200300 m 期间是大约 10001300 m。PBL 高度和喷雾器集中是相关反的在期间清楚并且薄雾条件。当平均喷雾器集中分别地是在薄雾和晴朗天空条件下面的 52 和 17 g/m3 时,平均最大的 PBL 高度是 1.08 和 1.70 km。太阳的放射上的喷雾器和云的影响基于从 255-m 收集的声音的风速表数据被观察气象学的塔。当 PBL 的镇压结构进一步削弱了污染物质的散开时,热流动被发现被薄雾(重污染) 或云显著地减少了,它趋于压抑 PBL 的发展,导致重污染。这个可能的积极反馈周期(更多的喷雾器降低 PBL 高度更多的喷雾器) 将在大城市为重地面污染导致一个加速过程。 | Jiannong Quan Yang Gao Qiang Zhang Xuexi Tie Junji Cao Suqin Han Junwang Meng Pengfei Chen Delong Zhao | 2013 | Particuology2013，11，1： | 51 |
| 2 | Prospective study of biofeedback retraining in patients with chronic idiopathic functional constipation显示文摘AIM: To determine the efficacy and long-term outcome of biofeedback treatment for chronic idiopathic constipation and to compare the efficacy of two modes of biofeedback (EMG-based and manometry-based biofeedback).METHODS: Fifty consecutive contactable patients included 8 cases of slow transit constipation, 36 cases of anorectic outlet obstruction and 6 cases of mixed constipation. Two modes of biofeedback were used for these 50 patients, 30 of whom had EMG-based biofeedback, and 20 had manometrybased biofeedback. Before treatment, a consultation and physical examination were done for all the patients, related information such as bowel function and gut transit time was documented, psychological test (symptom checkJist 90, SCL90)and anorectic physiological test and defecography were applied. After biofeedback management, all the patients were followed up. The Student′s t-test, chi-squared test and Logistic regression were used for statistical analysis.RESULTS: The period of following up ranged from 12 to 24months (Median 18 months). 70% of patients felt that biofeedback was helpful, and 62.5% of patients with constipation were improved. Clinical manifestations including straining, abdominal pain, bloating, were relieved, and less oral laxative was used. Spontaneous bowel frequency and psychological state were improved significantly after treatment. Patients with slow and normal transit, and those with and without paradoxical contraction of the anal sphincter on straining, benefited equally from the treatment. The psychological status rather than anorectal test could predict outcome. The efficacy of the two modes of biofeedback was similar without side effects.CONCLUSION: This study suggests that biofeedback has a long-term effect with no side effects, for the majority of patients with chronic idiopathic constipation unresponsive to traditional treatment. Pelvic floor abnormalities and transit time should not be the selection criteria for treatment. | JunWang Mao-HongLuo Qing-HuiQi Zuo-LiangDong | 2003 | World Journal of Gastroenterology2003，9，9： | 45 |
| 3 | A Genome Sequence of Novel SARS-CoV Isolates: the Genotype, GD-Ins29, Leads to a Hypothesis of Viral Transmission in South China显示文摘We report a complete genomic sequence of rare isolates (minor genotype) of theSARS-CoV from SARS patients in Guangdong, China, where the first few casesemerged. The most striking discovery from the isolate is an extra 29-nucleotidesequence located at the nucleotide positions between 27,863 and 27,864 (referredto the complete sequence of B J01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream ofthe N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29,suggests a significant genetic event and differentiates it from the previously re-ported genotype, the dominant form among all sequenced SARS-CoV isolates. A17-nt segment of this extra sequence is identical to a segment of the same size intwo human mRNA sequences that may interfere with viral genome replication andtranscription in the cytosol of the infected cells. It provides a new avenue for theexploration of the virus-host interaction in viral evolution, host pathogenesis, andvaccine development. | E‘deQin XiongleiHe WeiTian YongLiu WeiLi JieWen BingyinSi YongwuHu WenmingPeng LinTaug TaoJiang JianpingShi JiaJia YuZhang JiaYe Cui’eWang YujunHan JingqiangWang BaochangFan QingfaWu GuohuiChang WuchunCao ZuyuanXu RuifuYang JmgWang ManYu YanLi JingXu JunZhou YajumDeng XiaoyuLi JianfeiHu CaipingWang ChunxiaYan QingrunZhang JingyueBao GuoqingLi HaiqingZhang YilinZhang HuiZhao XiaoweiZhang ShuangliLi XiaoJieCheng XiuqingZhang BinLiu ChangqingZeng HuanmingYang WeijunChen LinFang ChangfengLi MengLei DaweiLi WeiTong XiangjunTian JianWang BoZhang SonggangLi XuehaiTan SiqiLiu WeiDong JunWang GaneKa-ShuWong JunYu QingyuZhu | 2003 | Genomics, Proteomics & Bioinformatics2003，1，2： | 6 |

METHODS: A retrospective study of 26 cases of lymphoma diagnosed by gastroscopic biopsy during 1999 to 2001 from gastroscopy files of Xijing Hospital was made. The diagnostic criteria were adopted according to the new classification of non-Hodgkin's lymphoma.
RESULTS: Twenty-six cases of primary gastric lymphoma consisting of 15 men and 11 women, aged between 23 to 76 years were recruited from 6 225 cases who Received gastroscopy. All of them were diagnosed by both endoscopic findings and histological examinations. Histologically, 23cases were MALToma (low grade) and 3 cases lymphoblastic lymphoma (high grade). Immunohistochemically, all cases were CD20 positive, while CK and EMA were negative.
CONCLUSION: The majority of the cases of primary lowgrade gastric lymphoma have morphologic and clinical features that justify their inclusion in the category of lowgrade lymphoma of mucosa associated lymphoid tissue. | HongCheng JunWang Chuan-ShanZhang Pei-SongYan Xiao-HuiZhang Pei-ZhenHu Fu-ChengMa | 2003 | World Journal of Gastroenterology2003，9，6： | 5 |
| 5 | Gene Identification and Expression Analysis of 86,136 Expressed Sequence Tags(EST)from the Rice Genome显示文摘Expressed Sequence Tag(EST)analysis has pioneered genome-wide gene discovery and expression profiling.In order to establish a gene expression index in the rice cultivar indica,we sequenced and analyzed 86,136 ESTs from nine rice cDNA libraries from the super hybrid cultivar LYP9 and its parental cultivars.We assembled these ESTs into 13,232 contigs and leave 8,976 singletons.Overall,7,497 sequences were found similar to the existing sequences in GenBank and 14,711 are novel.These sequences are classified by molecular function,biological process and pathways according to the Gene Ontology.We compared our sequenced ESTs with the publicly available 95,000 ESTs from japonica,and found little sequence variation,despite the large difference between genome sequences,We then assembled the combined 173,000 rice ESTs for further analysis.Using the pooled ESTs,we compared gene expression in metabolism pathway between rice and Arabidopsis according to KEGG.We further profiled gene expression patterns in different tissues,developmental stages,and in a conditional sterile mutant,after checking the libraries are comparable by means of sequence coverage.We also identified some possible library specific genes and a number of enzymes and transcription factors that contribute to rice development. | YanZhou JiabinTang MichaelG.Walker XiuqingZhang JunWang SongnianHu HuayongXu SigiLiu HuanmingYang JunYu JianWang YajunDeng JianhaiDong LinYe LiLin JunLi XuegangWang HaoHu YibinPan WeiLin WeiTian JingLiu LipingWei | 2003 | Genomics, Proteomics & Bioinformatics2003，1，1： | 4 |
| 6 | Determination of interface layer thickness of a pseudo two—phase system by extension of the Debye equation显示文摘The Debye equation with slit-smeared small angle x-ray scattering(SAXS) data is extended form an ideal two-phase system to a pseudo two-phase system with the presence of the interface layer,and a simple accurate solution is proposed to determine the average thickness of the interface layer in porous materials.This method is tested by experimental SAXS data,which were measured at 25℃,of organo-modified mesoporous silica prepared by condensation of tetraethoxysiland(TEOS) and methyltriethoxysilane(MTES) using non-ionic neutral surfactant as template under neutral condition. | ZhiHongLi YanJunGong MinPu DongWu YuHanSun JunWang YiLiu BaoZh | 2001 | Beijing Synchrotron Radiation Facility2001，，2： | 3 |
| 7 | An aptamer-based shear horizontal surface acoustic wave biosensor with a CVD-grown single- layered graphene film for high-sensitivity detection of a label-free endotoxin显示文摘The thickness of the sensitive layer has an important influence on the sensitivity of a shear horizontal surface acoustic wave(SH-SAW)biosensor with a delay-line structure and lower layer numbers of graphene produce better sensitivity for biological detection.Therefore,a label-free and highly sensitive SH-SAW biosensor with chemical vapor deposition(CVD-)-grown single-layered graphene(SLG)for endotoxin detection was developed in this study.With this methodology,SH-SAW biosensors were fabricated on a 36°Y-90°X quartz substrate with a base frequency of 246.2MHz,and an effective detection cell was fabricated using acrylic material.To increase the surface hydrophilicity,chitosan was applied to the surface of the SLG film.Additionally,the aptamer was immobilized on the surface of the SLG film by cross-linking with glutaraldehyde.Finally,the sensitivity was verified by endotoxin detection with a linear detection ranging from 0 to 100 ng/mL,and the detection limit(LOD)was as low as 3.53 ng/mL.In addition,the stability of this type of SH-SAW biosensor from the air phase to the liquid phase proved to be excellent and the specificity was tested and verified by detecting the endotoxin obtained from Escherichia coli(E.coli),the endotoxin obtained from Pseudomonas aeruginosa(P.aeruginosa),and aflatoxin.Therefore,this type of SH-SAW biosensor with a CVD-grown SLG film may offer a promising approach to endotoxin detection,and it may have great potential in clinical applications. | Junwang Ji Yiquan Pang Dongxiao Li Zheng Huang Zuwei Zhang Ning Xue Yi Xu Xiaojing Mu | 2020 | Microsystems & Nanoengineering2020，6，1： | 3 |
| 8 | CHARACTERISTICS OF SEDIMENT TRANSPORT ALONG A RIVER REACH WITH A RESERVOIR显示文摘Based on long-term measurements at three gauging stations,Toudaoguai,Fugu and Hequ,and one meteorological station,this article discusses the features of discharge (Q) and sediment concentration (CS) of a river reach of the Yellow River with a reservoir located in the Loess Plateau. The impacts of the local sub-watershed between Toudaoguai and Fugu gauging stations on sediment budget to the Yellow River have been analyzed. In addition,the deposition processes in the Tianqiao Reservoir have been investigated. Results show over 80% of the precipitation that falls in the local sub- watershed is unable to contribute to the Yellow River runoff process. It is found that the annual maximum sediment concentration is usually less than 30 kg/m3 during flood seasons at Toudaoguai Gauging Station,but the sediment concentration varies dramatically at Fugu Gauging Station. About 35% of the sediment eroded in the sub-watersheds between Toudaoguai and Fugu gauging stations was produced from the Huangfuchuan sub-watershed which has a drainage area accounting only for 10% of the drainage area between Toudaoguai and Fugu gauging stations. The Tianqiao Reservoir generally has deposition during the summer flood season,and scouring during the non-flood season. On average,over 85% of deposited sediment in the reservoir occurs in the 12 km long lower reservoir reach. The volume of annual deposition in the reservoir mainly depends on the volume of water from the local region between Hequ and Fugu gauging stations. | JueyiSUI ChengLIU DaxianFANG JunWANG | 2005 | International Journal of Sediment Research2005，20，2： | 3 |

| 10 | The E Protein Is a Multifunctional Membrane Protein of SARS-CoV显示文摘The E (envelope) protein is the smallest structural protein in all coronaviruses andis the only viral structural protein in which no variation has been detected. Weconducted genome sequencing and phylogenetic analyses of SARS-CoV. Based ongenome sequencing, we predicted the E protein is a transmembrane (TM) pro-tein characterized by a TM region with strong hydrophobicity and α-helix con-formation. We identified a segment (NH2-_L-Cys-A-Y-Cys-Cys-N_-COOH) in thecarboxyl-terminal region of the E protein that appears to form three disulfide bondswith another segment of corresponding cysteines in the carboxyl-terminus of the S(spike) protein. These bonds point to a possible structural association between theE and S proteins. Our phylogenetic analyses of the E protein sequences in all pub-lished coronaviruses place SARS-CoV in an independent group in Coronaviridaeand suggest a non-human animal origin. | QingfaWu YilinZhang HongLu JingWang XimiaoHe YongLiu ChenYe WeiLin JianfeiHu JiaJi JingXu JiaYe YongwuHu WenjunChen SonggangLi JunWang JiauWang ShengliBi HuanmingYang | 2003 | Genomics, Proteomics & Bioinformatics2003，1，2： | 2 |
| 11 | Experimental studies on ozonation of ethylenethiourea显示文摘The experimental study on ozonation of ethylenethiourea(ETU) is conducted.The reaction of gas-phase ETU with 0.63 × 10-6 mol/L ozone is carried out in a 200-L reaction chamber.The secondary organic aerosol(SOA) resulted from the ozonation of gas-phase ETU is observed with a scanning mobility particle size(SMPS).The rapid exponential growth of SOA reveals that the atmospheric lifetime of ETU vapor towards ozone reaction is less than four days.The ozonation of dry ETU particles,ETU-contained water droplets and ETU aqueous solution is investigated with a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer(VUVATOFMS).The formation of 2-imidazoline is observed in the ozonation of dry ETU particles and ETU-contained water droplets.The formation of 2-imidazoline and ethylenerea is observed in the ozonation of ETU aqueous solution. | Xinyu Dong Junwang Meng Bo Yang Yang Zhang Jie Gan XiShu Jinian Shu | 2011 | Journal of Environmental Sciences2011，23，1： | 2 |
| 12 | In-situ A1/24Si Functional Graded Materials Prepared by Electromagnetic Separation显示文摘Cylinder-like in-situ Al/24Si FGMs were produced by using electromagnetic separating process. Si primary phasereinforced layer with volume fraction as high as 16 pct was formed at the outer region of the cylinder-like sampleswhere the local hardness and wear resistance were enhanced remarkably. Moreover, both of strength and ductility inthe inner region provided insurance of reliable strength for this as-cast gradient material. It indicated that generalmechanical properties such as good wear resistance at the outer region and good ductility in the central part couldbe obtained with the optimized redistribution of the Si primary particles under the electromagnetic force. | KeLI JunWANG DaSHU BaodeSUN YaoheZHOU | 2002 | Journal of Materials Science & Technology2002，18，5： | 2 |
| 13 | A novel three primers PCR (TP-PCR) method to obtain recombinant DNA molecule independent of restriction enzyme显示文摘In this note, we report a novel and efficient three primers PCR (TP-PCR) method to rapidly generate recombinant DNA molecule at precise junction between two arbitrary DNA fragments. TP-PCR method is characterized by its reaction system with two templates and three primers, which can produce a recombinant DNA molecule in one PCR reaction. The main advantages of this method are the independence of sequences at the recombination site, the rapid-ness, and the easy establishment of adequate conditions.

| 15 | Ground-high altitude joint detection of ozone and nitrogen oxides in urban areas of Beijing显示文摘Based on observational data of ozone(O3) and nitrogen oxide(NOx) mixing ratios on the ground and at high altitude in urban areas of Beijing during a period of six days in November 2011,the temporal and spatial characteristics of mixing ratios were analyzed.The major findings include:urban O3 mixing ratios are low and NOx mixing ratios are always high near the road in November.Vertical variations of the gases are significantly different in and above the planetary boundary layer.The mixing ratio of O3 is negatively correlated with that of NOx and they are positively correlated with air temperature,which is the main factor directly causing vertical variation of O3 and NOx mixing ratios at 600-2100m altitude.The NOx mixing ratios elevated during the heating period,while the O3 mixing ratios decreased:these phenomena are more significant at high altitudes compared to lower altitudes.During November,air masses in the urban areas of Beijing are brought by northwesterly winds,which transport O3 and NOx at low mixing ratios.Due to Beijing's natural geographical location,northwest air currents are beneficial to the dilution and dispersion of pollutants,which can result in lower O3 and NOx background values in the Beijing urban area. | Pengfei Chen Qiang Zhang Jiannong Quan Yang Gao Delong Zhao Junwang Meng | 2013 | Journal of Environmental Sciences2013，25，4： | 1 |

| 17 | A Statistical Approach Designed for Finding Mathematically Defined Repeats in Shotgun Data and Determining the Length Distribution of Clone-Inserts显示文摘The large amount of repeats, especially high copy repeats, in the genomes of higher animals and plants makes whole genome assembly (WGA) quite difficult. In order to solve this problem, we tried to identify repeats and mask them prior to assembly even at the stage of genome survey. It is known that repeats of different copy number have different probabilities of appearance in shotgun data, so based on this principle, we constructed a statistical model and inferred criteria for mathematically defined repeats (MDRs) at different shotgun coverages. According to these criteria, we developed software MDRmasker to identify and mask MDRs in shotgun data. With repeats masked prior to assembly, the speed of assembly was increased with lower error probability. In addition, clone-insert size affects the accuracy of repeat assembly and scaffold construction. We also designed length distribution of clone-inserts using our model. In our simulated genomes of human and rice, the length distribution of repeats is different, so their optimal length distributions of clone-inserts were not the same. Thus with optimal length distribution of clone-inserts, a given genome could be assembled better at lower coverage. | LanZhong KunlinZhang XiangangHuang PeixiangNi YujunHan KaiWang JunWang SonggangLi | 2003 | Genomics, Proteomics & Bioinformatics2003，1，1： | 1 |

| 20 | The Solar Upper Transition Region Imager(SUTRI)Onboard the SATech-01 Satellite显示文摘The Solar Upper Transition Region Imager(SUTRI)onboard the Space Advanced Technology demonstration satellite(SATech-01),which was launched to a Sun-synchronous orbit at a height of~500 km in 2022 July,aims to test the on-orbit performance of our newly developed Sc/Si multi-layer reflecting mirror and the 2k×2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of~3 nm.SUTRI employs a Ritchey-Chrétien optical system with an aperture of 18 cm.The on-orbit observations show that SUTRI images have a field of view of~416×416 and a moderate spatial resolution of~8″without an image stabilization system.The normal cadence of SUTRI images is 30 s and the solar observation time is about16 hr each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period.Approximately15 GB data is acquired each day and made available online after processing.SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of~0.5 MK in the solar atmosphere,which has rarely been sampled by existing solar imagers.SUTRI observations will establish connections between structures in the lower solar atmosphere and corona,and advance our understanding of various types of solar activity such as flares,filament eruptions,coronal jets and coronal mass ejections. | Xianyong Bai Hui Tian Yuanyong Deng Zhanshan Wang Jianfeng Yang Xiaofeng Zhang Yonghe Zhang Runze Qi Nange Wang Yang Gao Jun Yu Chunling He Zhengxiang Shen Lun Shen Song Guo Zhenyong Hou Kaifan Ji Xingzi Bi Wei Duan Xiao Yang Jiaben Lin Ziyao Hu Qian Song Zihao Yang Yajie Chen Weidong Qiao Wei Ge Fu Li Lei Jin Jiawei He Xiaobo Chen Xiaocheng Zhu Junwang He Qi Shi Liu Liu Jinsong Li Dongxiao Xu Rui Liu Taijie Li Zhenggong Feng Yamin Wang Chengcheng Fan Shuo Liu Sifan Guo Zheng Sun Yuchuan Wu Haiyu Li Qi Yang Yuyang Ye Weichen Gu Jiali Wu Zhe Zhang Yue Yu Zeyi Ye Pengfeng Sheng Yifan Wang Wenbin Li Qiushi Huang Zhong Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，6： | 1 |
