| 1 | Performance value of high risk factors in colorectal cancer screening in China显示文摘AIM:To analyze the performance value of high risk factors in population-based colorectal cancer(CRC) screening in China.METHODS:We compared the performance value of the immunochemical fecal occult blood test(iFOBT) and other high risk factors questionnaire in a population sample of 13 214 community residents who completed both the iFOBT and questionnaire investigation.Patients with either a positive iFOBT and/or questionnaire were regarded as a high risk population and those eligible were asked to undergo colonoscopy.RESULTS:The iFOBT had the highest positive predictive value and negative predictive value in screening for advanced neoplasia.The iFOBT had the highest sensitivity,lowest number of extra false positive results associated with the detection of one extra abnormality for screening advanced neoplasias and adenomas.A history of chronic cholecystitis or cholecystectomy,chronic appendicitis or appendectomy,and chronic diarrhea also had a higher sensitivity than a history of adenomatous polyps in screening for advanced neoplasias and adenomas.The sensitivity of a history of chronic cholecystitis or cholecystectomy was highest among the 10 high risk factors in screening for nonadenomatous polyps.A history of chronic appendicitis or appendectomy,chronic constipation,chronic diarrhea,mucous and bloody stool,CRC in first degree relatives,malignant tumor and a positive iFOBT also had higher sensitivities than a history of adenomas polyps in screening for non-adenomatous polyps.Except for a history of malignant tumor in screening for non-adenomatous polyps,the gain in sensitivity was associated with an increase in extra false positive results associated with the detection of one extra abnormality.CONCLUSION:The iFOBT may be the best marker for screening for advanced neoplasias and adenomas.Some unique high risk factors may play an important role in CRC screening in China. | Wen Meng Shan-Rong Cai Lun Zhou Qi Dong Shu Zheng Su-Zhan Zhang | 2009 | World Journal of Gastroenterology2009，15，48： | 41 |
| 2 | Immunohistochemical study on p53,H-rasp21,c-erbB-2 protein and PCNA expression in HCC tissues of Hart and minority ethnic patients显示文摘AIM To find out the difference of humanprimary liver carcinogenesis between Han andminority ethnic patients in Xinjiang.METHODS Expression of p53,c-erbB-2,H-rasp21 protein and proliferating cell nuclearantigen(PCNA)in tumor tissues of 50 patients(Han 38,minority 12)with primary hepaticcarcinoma was detected byimmunohistochemistry(LSAB).RESULTS The positive frequency of p53,c-erbB-2,H-rasp21 and PCNA expression was46.0%(23/50),70.0%(35/50),68.0%(34/50)and 82.0%(41/50)in tumor tissues;4.0%(2/50),22.0%(11/50),64.0%(32/50)and 52.0%(26/ 50)in peritumors respectively and asignificant difference,except for H-rasp21,ofoncogene alteration was found(P<0.05)between tumor and non-tumorous tissues.Combined the three oncogenes alteration,26%(13/50)tumor tissues had positiveimmunoreactivity,but in peritumor and normallivers it was negative.The positive rate of p53,c-erbB-2 and H-rasp21 protein expression was39.5%(15/38),60.5%(23/38)and 39.5%(15/38)in tumors of Han patients;66.7%(8/12),100%(12/12)and 75.0%(9/12)in minoritiesrespectively,with statistical difference (P<0.05).CONCLUSION Overexpression of p53,c-erbB-2and H-rasp21 in human primary liver carcinoma isan important biomarker of genetic alteration.The different frequency of these oncogeneticchanges may reflect some environmental or/andethnic hereditary factors affecting the livercarcinogenesis.The special life style of Han,Uygur,Kazak and Mongolia nationalities inXinjiang may also be related to theetiopathogenesis of this disease. | Guo Yue Lin Zhao Lun Chen Cai Mo Lu Ying Li Xiao Jia Ping Rong Huang Department of Laboratory Medicine,Chinese PLA 474 Hospital,Urumqi 830011,Xinjiang Uygur Autonomic Region,China Department of Pathology,the 1st Teaching Hospital,Xinjiang Medical University,Urumqi 830054,Xinjiang Uygur Autonomic Region,China | 2000 | World Journal of Gastroenterology2000，6，2： | 40 |
| 3 | The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. | Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping | 2016 | Biomedical and Environmental Sciences2016，29，1： | 29 |

| 5 | Two New Group 3 LEA Genes of Wheat and Their Functional Analysis in Yeast显示文摘The group 3 late embryogenesis abundant (LEA) proteins are thought to protect cells from stresses associated with dehydration during periods of water deficit. To investigate the functions of different members of the group 3 LEA genes, we isolated and characterized two new group 3 LEA genes, namely TaLEA2 and TaLEA3, from wheat (Triticum aestivum L.) and introduced TaLEA2 and TaLEA3 into Saccharmyces cerevisiae to examine the effect of these genes on yeast cell tolerance to osmotic, salt, and cold stresses. The TaLEA2 gene encoded a protein of 211 amino acids and possessed five repeats of 11-mer amino acid motifs. The TaLEA3 gene encoded a polypeptide of 211 amino acids with nine repeated units.Overexpression of TaLEA2 and TaLEA3 improved stress tolerance in transgenic yeast cells when cultured in medium containing sorbitol, salt and-20 ℃ freezing treatments respectively. However, the yeast transformants with TaLEA2 seemed to be more tolerant to hyperosmotic and freezing stress than transformants with TaLEA3. This implies that a close relationship exists between function and the number of repeats of the 11-mer amino acid motif in the group 3 LEA protein. | Jia-Ning YU Jin-Song ZHANG Lun SHAN Shou-Yi CHEN | 2005 | Journal of Integrative Plant Biology2005，47，11： | 19 |

| 7 | A Review on Metal-Organic Framework-Derived Porous Carbon-Based Novel Microwave Absorption Materials显示文摘The development of microwave absorption materials(MAMs) is a considerable important topic because our living space is crowed with electromagnetic wave which threatens human’s health.And MAMs are also used in radar stealth for protecting the weapons from being detected.Many nanomaterials were studied as MAMs,but not all of them have the satisfactory performance.Recently,metal-organic frameworks(MOFs) have attracted tremendous attention owing to their tunable chemical structures,diverse properties,large specific surface area and uniform pore distribution.MOF can transform to porous carbon(PC) which is decorated with metal species at appropriate pyrolysis temperature.However,the loss mechanism of pure MOF-derived PC is often relatively simple.In order to further improve the MA performance,the MOFs coupled with other loss materials are a widely studied method.In this review,we summarize the theories of MA,the progress of different MOF-derived PC-based MAMs,tunable chemical structures incorporated with dielectric loss or magnetic loss materials.The different MA performance and mechanisms are discussed in detail.Finally,the shortcomings,challenges and perspectives of MOF-derived PC-based MAMs are also presented.We hope this review could provide a new insight to design and fabricate MOF-derived PC-based MAMs with better fundamental understanding and practical application. | Zhiwei Zhang Zhihao Cai Ziyuan Wang Yaling Peng Lun Xia Suping Ma Zhanzhao Yin Yi Huang | 2021 | Nano-Micro Letters2021，13，4： | 17 |
| 8 | Experimental exploration and research prospect of physical bases and functional characteristics of meridians显示文摘The physical basis of meridians and acupoints (acupuncture points) is in a complex system mainly of connective tissue and interwoven with the blood capillaries, nerves, lymph vessels,etc. Elements of Ca, P, K, Fe, Zn, Mn, etc are found concentrated in the deep connective tissue structures in locations corresponding to acupoints. On this physical basis, the specific waveband of high efficiency for transmission of infrared rays exists in the collagenous fibre in a liquid crystal state. The development direction and new idea of researching on acupuncture and meridians are discussed. | Lun Fei Huansheng Cheng Deheng Cai Shixun Yang Jianrong Xu Eryu Chen Ruishan Dang Guanghong Ding Xueyong Shen Yi Tang et al. | 1998 | Chinese Science Bulletin1998，43，15： | 15 |
| 9 | Nitrous oxide emissions from a maize field during two consecutive growing seasons in the North China Plain显示文摘Nitrous oxide (N 2 O) emissions from a maize field in the North China Plain (Wangdu County,Hebei Province,China) were investigated using static chambers during two consecutive maize growing seasons in the 2008 and 2009.The N 2 O pulse emissions occurred with duration of about 10 days after basal and additional fertilizer applications in the both years.The average N 2 O fluxes from the CK (control plot,without crop,fertilization and irrigation),NP (chemical N fertilizer),SN (wheat straw returning plus chemical N fertilizer),OM- 1/2N (chicken manure plus half chemical N fertilizer) and OMN (chicken manure plus chemical N fertilizer) plots in 2008 were 8.51,72.1,76.6,101,107 ng N/(m 2 ·sec),respectively,and in 2009 were 33.7,30.0 and 35.0 ng N/(m 2 ·sec) from CK,NP and SN plots,respectively.The emission factors of the applied fertilizer as N 2 O-N (EFs) were 3.8% (2008) and 1.1% (2009) for the NP plot,3.2% (2008) and 1.2% (2009) for the SN plot,and 2.8% and 2.2% in 2008 for the OM-1/2N and OMN plots,respectively.Hydromorphic properties of the investigated soil (with gley) are in favor of denitrification.The large differences of the soil temperature and water-filled pore space (WFPS) between the two maize seasons were suspected to be responsible for the significant yearly variations.Compared with the treatments of NP and SN,chicken manure coupled with compound fertilizer application significantly reduced fertilizer loss rate as N 2 O-N. | Yuanyuan Zhang Junfeng Liu Yujing Mu Zhu Xu Shuwei Pei Xiaoxiu Lun Ying Zhang | 2012 | Journal of Environmental Sciences2012，24，1： | 15 |

| 14 | Change of water use efficiency and its relation with root system growth in wheat evolution显示文摘Raising crop water use efficiency (WUE) is the physiological basis to implement crop high efficiently using water. The present soil column and field experiments are designed to investigate the change of wheat WUE (Triticum aestivum L.) at whole plant level and root system growth in evolution and the relationship between WUE and its root system growth using 10 wheat evolution genotypes with different ploidy chromosomes sets. Results show that in wheat evolution from 2n→6n, WUE at whole plant level increases with the increase of ploidy chromosomes, and root system growth (root weight, root length) and root/shoot ratio of wheat decrease with the increase of ploidy chromosomes under dry and irrigated conditions. WUE is negatively correlated with root weight and root/shoot ratio of wheat in evolution, significantly. Root system growth has an adverse redundancy for WUE in wheat evolution, and the root redundancy reduces with the increase of ploidy chromosomes, which result in the increase of wheat WUE at | ZHANG Suiqi SHAN Lun DENG Xiping | 2002 | Chinese Science Bulletin2002，47，22： | 13 |

| 16 | Numerical study on ULF waves in a dipole field excited by sudden impulse显示文摘A three-dimensional numerical model is employed to investigate ULF waves ex-cited by the sudden impulse (SI) of the solar wind dynamic pressure interacting with a dipole magnetosphere. We focus on the solar wind-magnetosphere energy coupling through ULF waves, and the influences of the SI spectrum on the cavity mode structure and the energy deposition due to field line resonances (FLRs) in the magnetosphere. The numerical results show that for a given SI lasting for 1 min with amplitude of 50 mV/m impinging on the subsolar magnetopause, the total ULF energy transported from the solar wind to the magnetosphere is about the magni-tude of 1014 J. The efficiency of the solar wind energy input is around 1%, which depends little on the location of the magnetopause in the model. It is also found that the energy of the cavity mode is confined in the region near the magnetopause, whereas, the energy of the toroidal mode may be distributed among a few specific L-shells. With a given size of the model magnetosphere and plasma density distri-bution, it is shown that the fundamental eigenfrequency of the cavity mode and the central locations of the FLRs do not vary noticeably with the power spectrum of the SI. It is worth noting that the spectrum of the SI affects the excitation of higher harmonics of the global cavity mode. The broader the bandwidth of the SI is, the higher harmonics of cavity mode could be excited. Meanwhile, the corresponding FLRs regions are broadened at the same time, which implies that the global cavity modes and toroidal modes can resonate on more magnetic L-shells when more harmonics of the global cavity modes appear. | YANG Biao FU SuiYan ZONG QiuGang WANG YongFu ZHOU XuZhi PU ZuYin XIE Lun | 2008 | Science China(Technological Sciences)2008，51，10： | 12 |
| 17 | Geochemical characteristics and genetic model of dolomite reservoirs in the eastern margin of the Pre-Caspian Basin显示文摘The widespread Carboniferous KT-I dolomite in the eastern margin of the Pre-Caspian Basin is an important hydrocarbon reservoir. The dolomite lithology is dominated by crystalline dolomite. The δ18O values range from -6.71‰ to 2.45‰, and average 0.063‰, obviously larger than -2.5‰, indicating low-temperature dolomite of evaporation origin. Stable strontium isotope ratios (87Sr/86Sr) range from 0.70829 to 0.70875 and average 0.708365, very consistent with 87Sr/86Sr ratios in Carboniferous seawater. Chemical analysis of Ca and Mg elements shows that the dolomite has 9.1 mole% excess Ca or even higher before stabilization. The degree of order of dolomite is medium-slightly poor, varying in a range of 0.336-0.504 and averaging 0.417. It suggests that the dolomite formed under near-surface conditions. There are two models for the origin of the Carboniferous KT-I dolomite reservoir. These are 1) the evaporation concentration - weathering crust model and 2) the shoal facies - seepage reflux model. The former is mainly developed in restricted platforms - evaporate platforms of restricted marine deposition environments with a representation of dolomite associated with gypsum and mudstone. The latter mainly formed in platform edge shoals and intra-platform shoals and is controlled by dolomitization due to high salinity sea water influx from adjacent restricted sea or evaporate platform. | Wang Shuqin Zhao Lun Cheng Xubin Fan Zifei He Ling | 2012 | Petroleum Science2012，9，2： | 12 |
| 18 | CH_4 emission and conversion from A^2O and SBR processes in full-scale wastewater treatment plants显示文摘Wastewater treatment systems are important anthropogenic sources of CH4emission. A full-scale experiment was carried out to monitor the CH4 emission from anoxic/anaerobic/oxic process(A2O) and sequencing batch reactor(SBR) wastewater treatment plants(WWTPs) for one year from May 2011 to April 2012. The main emission unit of the A2O process was an oxic tank, accounting for 76.2% of CH4emissions; the main emission unit of the SBR process was the feeding and aeration phase, accounting for 99.5% of CH4emissions. CH4can be produced in the anaerobic condition, such as in the primary settling tank and anaerobic tank of the A2O process. While CH4can be consumed in anoxic denitrification or the aeration condition, such as in the anoxic tank and oxic tank of the A2O process and the feeding and aeration phase of the SBR process. The CH4emission flux and the dissolved CH4concentration rapidly decreased in the oxic tank of the A2O process. These metrics increased during the first half of the phase and then decreased during the latter half of the phase in the feeding and aeration phase of the SBR process. The CH4oxidation rate ranged from 32.47% to 89.52%(mean: 67.96%) in the A2O process and from 12.65% to 88.31%(mean: 47.62%) in the SBR process. The mean CH4 emission factors were 0.182 g/ton of wastewater and 24.75 g CH4 /(person·year) for the A2O process, and 0.457 g/ton of wastewater and 36.55 g CH4 /(person·year) for the SBR process. | Yan Liu Xiang Cheng Xiaoxiu Lun Dezhi Sun | 2014 | Journal of Environmental Sciences2014，26，1： | 12 |
| 19 | Multi-spacecraft observations of ULF waves during the recovery phase of magnetic storm on October 30, 2003显示文摘Based on observations obtained by Cluster C1, GOES 10, 12, and Polar, the global ULF wave properties are studied during the recovery phase of a very intense magnetic storm-Halloween storm (October 31, 2003, 21:00-23:00 UT). The results indicate that the ULF waves’ properties observed by different satellites, such as amplitude, period, etc. show large variations. This can be interpreted as that Field Line Resonance (FLR) might take place in the region where Cluster C1 passed. The compressional wave of the cavity mode coupled with FLR’s shear Alfven wave and fed energy to the latter, forming a large-amplitude toroidal mode. From the point of period, Cluster C1 observed the shortest period, GOES 10, 12 observed the middle, while Polar observed the longest. The wave period of toroidal mode observed by Cluster C1 kept almost unchanging when Cluster C1 passed L range from 11.7 to 5.3. Using the Squared Wavelet Coherence analysis method, we estimated that the FLR region in the dayside magnetosphere could expand to at least 4 local time widths. The toroidal mode observed by Polar was a standing wave, while the pol-oidal mode was a propagating wave, the observation results could be well ex-plained by the waveguide mode theory. Since the solarwind speed Vx was -800 km/s and the dynamic pressure varied little, we speculated that the source of the ULF wave was the Kelvin-Helmholtz instability at the magnetopause triggered by high speed solarwind. | YongFu Wang SuiYan Fu QiuGang Zong Biao Yang ZuYin Pu Lun Xie XuZhi Zhou | 2008 | Science China(Technological Sciences)2008，51，10： | 11 |
| 20 | Temperature variability since A.D.1837 inferred from tree-ring maximum density of Abies fabri on Gongga Mountain,China显示文摘Two tree-ring MXD (maximum latewood density) chronologies of Abies fabri were developed from the eastern slopes of Gongga Mountain, and a regional chronology (RC) was established based on the two MXD chronologies. There were significant positive correlations between the three MXD chronologies and August-September temperature, and the RC had the highest correlation (r=0.733, n=48, P<0.001) with mean August-September temperature. Based on growth-climate analyses, we reconstructed mean August-September temperature during the past 171 years for the study area. The reconstruction explained 53.5% of the instrumental temperature variance during the period 1960-2007 (F=52.8, R2adj =52.4%). In the past 171 years, there were 22 very warm years and 23 very cold years, four cold periods (1837-1842, 1884-1891, 1899-1905 and 1984-1989) and three warm periods (1966-1973, 1916-1924 and 1876-1881). Our reconstruction was validated by other tree ring-based temperature reconstructions from the surrounding area and documented climate disaster events. | DUAN JianPing WANG Lily LI Lun CHEN KeLong | 2010 | Chinese Science Bulletin2010，55，26： | 11 |
