| 2 | Influence of Different Extraction and Purification Methods on Astragalus Polysaccharides and Pharmacological Evaluation显示文摘Objective To clarify the influence on component and pharmacological action of Astragalus polysaccharides(APS) as complementary therapeutic agents prepared by different extraction and purification techniques.Methods Components of APS prepared by different extraction and purification techniques were analyzed,and these APS were used for synergy and attenuation of chemotherapy,radiotherapy treatment with H22 liver cancer and Lewis lung cancer of tumor-bearing mice,and also used for the regulation of immune function to immunosuppression mice.Results Experimental data were analyzed by means of statistical method to get pharmaco-result:A3(extracted by microwave assistance and purified by membrane separation)>A4(extracted by refluxing and purified by membrane separation)>A1(extracted by refluxing and no purification)≈A2(extracted by microwave assistance and no purification).There were no significant differences on pharmacodynamic action between A1 and A2.However,compared with A1 and A2,it was worth noting that A3 and A4 exhibited good pharmacodynamic action.Then A3-in and A4-in,the samples in dialyzer after dialysis,were separated and purified to get homogeneous APS,which were the principal constituents of APS in dialyzer,with the molecular weight(Mw) of 7669 and 14142 determined by HPGPC,respectively.The average Mw of APS outside of the dialyzer,A3-out was 3102 and A4-out 3256,which were the main compositions of A3 and A4,accounted for 79.63% and 53.92%,respectively.Conclusion APS with Mw about 5000 Da exhibit better antitumor effect and immunological activity.Refluxing,microwave assistance extractions,and membrane enrichment techniques bring different cases on Mw distribution,components and pharmacodynamic action,and obviously exhibit relationship among component,Mw distribution,and pharmacological action. | YANG Yi-fang1,FENG Jing-qian1,XU Hai-yan1,PENG Dan-ming2,HU Jian-ping2 1.Shanghai Institute of Pharmaceutical Industry,Shanghai 200040,China 2.Jiangxi Provincial Academy of Traditional Chinese Medicine,Nanchang 330077,China | 2010 | Chinese Herbal Medicines2010，2，1： | 24 |
| 3 | Epidemiology of urolithiasis in Asia显示文摘In Asia,about 1%-19.1% of the population suffer fromurolithiasis.However,due to variations in socio-economic status and geographic locations,the prevalence and incidence have changed in different countries or regions over the years.The research for risk factors of urinary tract stones is of predominant importance.In this review,we find the prevalence of urolithiasis is 5%-19.1% in West Asia,Southeast Asia,South Asia,aswellas somedevelopedcountries(SouthKorea and Japan),whereas,it is only 1%e8%inmost part of East Asia and North Asia.The recurrence rate ranges from 21% to 53% after 3e5 years.Calciumoxalate(75%-90%)is themost frequent component of calculi,followed by uric acid(5%-20%),calciumphosphate(6%-13%),struvite(2%-15%),apatite(1%)and cystine(0.5%-1%).The incidence of urolithiasis reaches its peak in population agedover 30 years.Males aremore likely to suffer fromurinary calculi.Because of different dietary habits or genetic background,differences of prevalence among races or nationalities also exist.Geneticmutation of specific locus may contribute to the formation of different kinds of calculi.Dietary habits(westernized dietary habits and less fluid intake),as well as climatic factors(hot temperature andmany hours of exposure to sunshine)play a crucial role in the development of stones.Other diseases,especially metabolic syndrome,may also contribute to urinary tract stones. | Yu Liu Yuntian Chen Banghua Liao Deyi Luo Kunjie Wang Hong Li Guohua Zeng | 2018 | Asian Journal of Urology2018，5，4： | 24 |

| 6 | The concept of effective emissivity of nonisothermal mixed pixel and its test显示文摘Based on two preconditions, the local thermal equilibrium is satisfied and emissivities donot change with temperature, the concept of component effective emissivity of nonisothermal mixed pixel has been put forward and then the radiant directionality model of nonisothermal mixed pixel constructed from it. Our study shows that the component effective emissivity is associated with geometric structure, optical properties of target, and viewing angle, but does not depend on the component temepratures. The component temperatures can only change the ratio of component radiance to the total radiance of the mixed-pixel. The total effective emissivity of this pixel is the complement of its directional-hemisphere reflectance. After the simulation of component effective emissivity of the discrete cones and continuous vegetation canopy (winter wheat) by the Monte Carlo method, our model of radiant directionality of nonisothermal mixed pixel have been proved by lab and field measurements. | CHEN Liangfu ZHUANG Jiali XU Xiru NIU Zheng ZHANG Renhua XIANG Yueqing | 2000 | Chinese Science Bulletin2000，45，9： | 17 |

| 8 | Physiological mechanisms of resistance to cold stress associated with 10 elite apple rootstocks显示文摘A study was conducted in attempting to identify the cold-resistant apple rootstocks and to establish a comprehensive evaluation system. In this study, 10 elite apple dwarfing rootstocks(GM256, JM7, M26, M7, SC1, SH1, SH38, SH6, M9, and T337) were employed for the experiment and the following parameters were investigated under different low temperature stress conditions(0, –15, –20, –25, –30, and –35°C): the changes of the relative electrical conductivity(REC), anthocyanin content, protein content, soluble sugar content, soluble starch content, proline content, malondialdehyde(MDA) content, superoxide dismutase(SOD) activity, and peroxidase(POD) activity of the dormant branches. The inflection temperature that could represent the plant tissue semi-lethal temperature(LT_(50)) was obtained by the measurements of REC. The LT_(50) was used to evaluate eight other indices. The results showed that there was no significant correlation between LT_(50) and POD activity as well as between the soluble sugar, protein and proline contents at 0 and –15°C. Soluble starch content at 0 and –15°C and anthocyanin content at –15–(–30)°C were significantly but negatively correlated to the LT50 and the MDA content at 0–(–20)°C was significantly positively correlated to the LT_(50). Statistical analysis based on principal component analysis and LT50 showed that cold resistant apple rootstocks in the decreasing order from high to low as GM256, SH6, SH38, SH1, SC1, M26, M7, JM7, T337, and M9. | WANG Yan-xiu HU Ya CHEN Bai-hong ZHU Yan-fang Mohammed Mujitaba Dawuda Sofkova Svetla | 2018 | Journal of Integrative Agriculture2018，17，4： | 15 |

| 12 | Characterizing and estimating rice brown spot disease severity using stepwise regression,principal component regression and partial least-square regression显示文摘Detecting plant health conditions plays a key role in farm pest management and crop protection. In this study, measurement of hyperspectral leaf reflectance in rice crop (Oryzasativa L.) was conducted on groups of healthy and infected leaves by the fungus Bipolaris oryzae (Helminthosporium oryzae Breda. de Hann) through the wavelength range from 350 to 2 500 nm. The percentage of leaf surface lesions was estimated and defined as the disease severity. Statistical methods like multiple stepwise regression, principal component analysis and partial least-square regression were utilized to calculate and estimate the disease severity of rice brown spot at the leaf level. Our results revealed that multiple stepwise linear regressions could efficiently estimate disease severity with three wavebands in seven steps. The root mean square errors (RMSEs) for training (n=210) and testing (n=53) dataset were 6.5% and 5.8%, respectively. Principal component analysis showed that the first principal component could explain approximately 80% of the variance of the original hyperspectral reflectance. The regression model with the first two principal components predicted a disease severity with RMSEs of 16.3% and 13.9% for the training and testing dataset, respec-tively. Partial least-square regression with seven extracted factors could most effectively predict disease severity compared with other statistical methods with RMSEs of 4.1% and 2.0% for the training and testing dataset, respectively. Our research demon-strates that it is feasible to estimate the disease severity of rice brown spot using hyperspectral reflectance data at the leaf level. | LIU Zhan-yu1, HUANG Jing-feng1, SHI Jing-jing1, TAO Rong-xiang2, ZHOU Wan3, ZHANG Li-li3 (1Institute of Agriculture Remote Sensing and Information System Application, Zhejiang University, Hangzhou 310029, China) (2Institute of Plant Protection and Microbiology, Zhejiang Academy of Agricultural Sciences, Hangzhou 310021, China) (3Plant Inspection Station of Hangzhou City, Hangzhou 310020, China) | 2007 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2007，8，10： | 13 |

| 14 | Extracting mineral alteration information using WorldView-3 data显示文摘The multispectral commercial satellite-WorldView-3(WV-3) has the highest spatial, spectral and radiation resolutions among the satellites currently and can generate good data in the shortwave infrared(SWIR). The study area is located in the Pobei area of Xinjiang Uygur Autonomous Region, which is rich in mineral resources. The spectral analyses of some typical altered hydroxy-bearing, iron-bearing, and carbonate-bearing minerals could establish several Principal Component Analysis(PCA) models and mineral indices, using the visible and near infrared(VNIR) and the shortwave infrared(SWIR) subsystems of WV-3 data. In addition, the Spectral Angle Method and the spectrum index tool of ENVI software were used to extract the relevant alteration information. The WV-3 data is well suited for identifying hydroxy-bearing alteration with rich SWIR bands which distinguish Al-OH-bearing from MgOH-bearing alteration. Hence, this study provides a basis for the prediction of mineral resources in the Pobei area and sets the foundation for WV-3 data to be used as an important tool in extracting alteration information and prospecting practices. | Yaqin Sun Shufang Tian Baogang Di | 2017 | Geoscience Frontiers2017，8，5： | 13 |
| 15 | A review on carbon/magnetic metal composites for microwave absorption显示文摘At present,developing high-efficiency microwave absorption materials with properties including lightweight,thin thickness,strong absorbing intensity and broad bandwidth is an urgent demand to solve the electromagnetic pollution issues.An ideal microwave absorber should have excellent dielectric and magnetic loss capabilities,thereby inducing attenuation and absorption of incident electromagnetic radiation.Recently,various carbon/magnetic metal composites have been developed and expected to become promising candidates for high-performance microwave absorbers.In this review,we introduce the mechanisms of microwave absorption and summarize the recent advances in carbon/magnetic metal composites.Preparation methods and microwave absorption properties of carbon/magnetic metal composites with different components,morphologies and microstructures are discussed in detail.Finally,the challenges and future prospects of carbon/magnetic metal absorbing materials are also proposed,which will be useful to develop high-performance microwave absorption materials. | Baolei Wang Qian Wu Yonggang Fu Tong Liu | 2021 | Journal of Materials Science & Technology2021，，27： | 13 |
| 16 | Accumulation and potential sources of heavy metals in soils of the Hetao area,Inner Mongolia,China显示文摘Soil contamination by heavy metals is a problem in agricultural irrigation systems.To assess the accumulation and sources of heavy metals in the Yongji irrigation district of the Hetao area,Inner Mongolia,China,195 soil samples from 39 sites(0–100 cm)were collected,and Zn,Cu,Pb,Cr,and Cd concentrations were analyzed.The mean concentrations were 107.17,32.48,12.31,53.53,and 0.22 mg kg-1,respectively,with no significant differences between soil depths(P>0.05).Concentrations of Zn,Cu,and Cd were higher than the background levels,with moderate accumulation;the contamination factor(CF)values were 1.9,1.7,and 1.9,respectively,and the geoaccumulation index(Igeo)was>0.Concentrations of Pb and Cr were lower than,or close to,the background levels(CF<1,Igeo<0),indicating that they originated from a natural source.The monomial potential ecological risk index(Eri)for Zn,Cu,Pb,and Cr was low;Eri for Cd was 55.73,implying a moderate risk.The grade of potential ecological risk index of the five heavy metals(RI)was low,declining from south to north.The studied soils were contaminated with Zn,Cu,and Cd;principal component(PC)analysis implicated the enrichment of Cd and partial Cu(high loading in PC 2)was related to agricultural activities;Zn and partial Cu,closely associated with PC 3,may have originated from irrigation water from the Yellow River.Future agricultural development should focus on fertilizer and pesticide application and the quality of irrigation water. | Yangchun ZHU Lijin WANG Xueyong ZHAO Jie LIAN Zhenhua ZHANG | 2020 | Pedosphere2020，30，2： | 12 |
| 17 | A Study on Retrieving Atmospheric Profiles from EOS/AIRS Observations显示文摘The paper presents the algorithms for retrieving atmospheric temperature and moisture profiles and surface skin temperature from the high-spectral-resolution Atmospheric Infrared Sounder (AIRS) with a statistical technique based on principal component analysis. The synthetic regression coefficients for the statistical retrieval are obtained by using a fast radiative transfer model with atmospheric characteristics taken from a dataset of global radiosondes of atmospheric temperature and moisture profiles. Retrievals are evaluated by comparison with radiosonde observations and European Center of Medium-Range Weather Forecasts (ECMWF) analyses. AIRS retrievals of temperature and moisture are in general agreement with the distributions from ECMWF analysis fields and radiosonde observations, but AIRS depicts more detailed structure due to its high spectral resolution (hence, high vertical spatial resolution). | 官莉 ALLEN Huang 李俊 | 2005 | Acta meteorologica Sinica2005，19，1： | 11 |
| 18 | Bionic optimization research of soil cultivating component design显示文摘The basic biomechanical laws that apply to the clawed toes of animals with powerful digging abilities and the optimal bionic design of curved soil cultivating components with an analogous contour were researched in a novel way. First, the curvature and profile of the inside contour line of a field mouse’s clawed toe were analyzed. The finite element method (FEM) was then used to simulate the working process in order to study the changing characteristics of the working resistance of bionic soil- engag- ing surfaces and the stress field of the processed soil. A straight-line cultivating component was used for comparative analysis. In accordance with the simulation results, a series of soil cultivating com- ponents of varying design were manufactured. An indoor soil bin experiment was carried out to meas- ure their working resistance and validate the results of the FEM analysis. The results of this research would have important values in the optimization design of cultivating components for energy and cost savings. | GUO ZhiJun ZHOU ZhiLi ZHANG Yi LI ZhongLi | 2009 | Science China(Technological Sciences)2009，52，4： | 11 |
