| 1 | Influences of blood lipids on the occurrence and prognosis of hemorrhagic transformation after acute cerebral infarction: a case-control study of 732 patients显示文摘Background: To study the influence of blood lipid levels on hemorrhagic transformation(HT) and prognosis after acute cerebral infarction(ACI).Methods: Patients with ACI within 72 h of symptoms onset between January 1 st, 2015, and December 31 st, 2016, were retrospectively analyzed. Patients were divided into group A(without HT) and group B(HT). The outcomes were assessed after 3 months of disease onset using the modified Rankin Scale(m RS). An m RS score of 0–2 points indicated excellent prognosis, and an m RS score of 3–6 points indicated poor prognosis.Results: A total of 732 patients conformed to the inclusion criteria, including 628 in group A and 104 in group B. The incidence of HT was 14.2%, and the median onset time was 2 d(interquartile range, 1–7 d). The percentages of patients with large infarct size and cortex involvement in group B were 80.8% and 79.8%, respectively, which were both significantly higher than those in group A(28.7 and 33.4%, respectively). The incidence rate of atrial fibrillation(AF) in group B was significantly higher than that in group A(39.4% vs. 13.9%, P<0.001). The adjusted multivariate analysis results showed that large infarct size, cortex involvement and AF were independent risk factors of HT, while total cholesterol(TC) was a protective factor of HT(OR=0.359, 95% CI 0.136–0.944, P=0.038). With every 1 mmol/L reduction in normal TC levels, the risk of HT increased by 64.1%. The mortality and morbidity at 3 months in group B(21.2% and 76.7%, respectively) were both significantly higher than those in group A(8.0% and 42.8%, respectively). The adjusted multivariate analysis results showed that large infarct size(OR=12.178, 95% CI 5.390–27.516, P<0.001) was an independent risk factor of long-term unfavorable outcomes, whereas low-density lipoprotein cholesterol(LDL-C) was a protective factor(OR=0.538, 95% CI 0.300–0.964, P=0.037). With every 1 mmol/L reduction in normal LDL-C levels, the risk of an unfavorable outcome increased by 46.2%. Major therapies, including intravenous recombinant human tissue plasminogen activator(r TPA), intensive lipid-lowering statins and anti-platelets, were not significantly related to either HT or long-term, post-ACI poor prognosis.Conclusions: For patients with large infarct sizes, especially those with cortex involvement, AF, or lower levels of TC, the risk of HT might increase after ACI. The risk of a long-term unfavorable outcome in these patients might increase with a reduction in LDL-C. | Gang Lv Guo-Qiang Wang Zhen-Xi Xia Hai-Xia Wang Nan Liu Wei Wei Yong-Hua Huang Wei-Wei Zhang | 2019 | Military Medical Research2019，6，3： | 60 |
| 2 | Bowel preparation quality scales for colonoscopy显示文摘Colorectal cancer(CRC) is the third most common cancer and second leading cause of cancer-related death in the United States. Colonoscopy is widely preferred for CRC screening and is the most commonly used method in the United States. Adequate bowel preparation is essential for successful colonoscopy CRC screening. However, up to one-quarter of colonoscopies are associated with inadequate bowel preparation, which may result in reduced polyp and adenoma detection rates, unsuccessful screens, and an increased likelihood of repeat procedure. In addition, standardized criteria and assessment scales for bowel preparation quality are lacking. While several bowel preparation quality scales are referred to in the literature, these differ greatly in grading methodology and categorization criteria. Published reliability and validity data are available for five bowel preparation quality assessment scales, which vary in several key attributes. However, clinicians and researchers continue to use a variety of bowel preparation quality measures, including nonvalidated scales, leading to potential confusion and difficulty when comparing quality results among clinicians and across clinical trials. Optimal clinical criteria for bowel preparation quality remain controversial. The use of validated bowel preparation quality scales with stringent but simple scoring criteria would help clarify clinical trial data as well as the performance of colonoscopy in clinical practice related to quality measurements. | David Kastenberg Gerald Bertiger Stuart Brogadir | 2018 | World Journal of Gastroenterology2018，24，26： | 38 |
| 3 | Experimental study on scale inhibition performance of a green scale inhibitor polyaspartic acid显示文摘Static and dynamic experiments were carried out to validate scale inhibition performance of a green scale inhibitor-polyaspartic acid (PASP). From the static experiment, it was shown that below 60℃, polyaspartic acid is very effective in scale inhibition, with the scale inhibition ratio exceeding 90% with only 3 mg/L PASP for the 600 mg/L hardness solution. For a higher hardness solution of 800 mg/L, the scale inhibition ratio can also reach 90% with 6 and 12 mg/L PASP at 30 and 60℃respectively. The SEM photographs of CaCO3 crystals indicate that the crystal structure transforms from a compact stick-shape to a loose shape so that the scale can be washed away easily instead of being deposited on the heat transfer surface. The dynamic experimental results show that almost no scales formed on the heat trans- fer surface and the fouling thermal resistance decreases extraordinarily if PASP is added in the solution. | QUAN ZhenHua CHEN YongChang WANG XiuRong SHI Cheng LIU YunJie MA ChongFang | 2008 | Science China Chemistry2008，51，7： | 18 |
| 4 | Investigation of scale inhibition mechanisms based on the effect of scale inhibitor on calcium carbonate crystal forms显示文摘To probe the scale inhibition mechanisms,calcium carbonate scale occurring before and after the ad- dition of scale inhibitors was collected.The results from scale SEM confirm that,without scale inhibitor, calcium carbonate scale shows rhombohedron and hexagon,which are the characteristic feathers of calcite.After addition of inhibitors,morphology of scale is changed,and the more efficient the scale inhibitor is,the more greatly the morphology is modified.To elucidate the scale constitute,they were further analyzed by FT-IR,XRD.Besides calcite,vaterite and aragonite occur in calcium carbonate scale after addition of inhibitors,and the higher scale inhibition efficiency is,the more vaterite presents in scale.It can be concluded that the alteration of morphology is ascribed to the change of crystal form. There are three stages in the crystallizing process including occurrence and disappearing of unstable phase,occurrence and disappearing of metastable phase,development of stable phase.Without scale inhibitors,metastable phases usually transform into stable phase,thus the main constitute of formed scale is calcite.When scale inhibitors are added,both formation and transformation of metastable phases are inhibited,which results in the occurrence of aragonite and vaterite.From the fact that more vaterite presents in scale with a more efficient scale inhibitor added,we can see that the function of scale inhibitor is realized mainly by controlling the crystallizing process at the second stage. | ZHANG GuiCai GE JiJiang SUN MingQin PAN BinLin MAO Tao SONG ZhaoZheng | 2007 | Science China Chemistry2007，50，1： | 17 |
| 5 | Object-oriented land cover classification using HJ-1 remote sensing imagery显示文摘The object-oriented information extraction technique was used to improve classification accuracy,and addressed the problem that HJ-1 CCD remote sensing images have only four spectral bands with moderate spatial resolution.We used two key techniques:the selection of optimum image segmentation scale and the development of an appropriate object-oriented information extraction strategy.With the principle of minimizing merge cost of merging neighboring pixels/objects,we used spatial autocorrelation index Moran's I and the variance index to select the optimum segmentation scale.The Nearest Neighborhood(NN) classifier based on sampling and a knowledge-based fuzzy classifier were used in the object-oriented information extraction strategy.In this classification step,feature optimization was used to improve information extraction accuracy using reduced data dimension.These two techniques were applied to land cover information extraction for Shanghai city using a HJ-1 CCD image.Results indicate that the information extraction accuracy of the object-oriented method was much higher than that of the pixel-based method. | SUN ZhongPing1,SHEN WenMing1,WEI Bin1,LIU XiaoMan1,SU Wei2,ZHANG Chao2 & YANG JianYu2 1 Satellite Environment Center,Ministry of Environmental Protection,Beijing 100094,China 2 College of Information and Electrical Engineering,China Agricultural University,Beijing 100083,China | 2010 | Science China Earth Sciences2010，53，S1： | 15 |
| 6 | Experimental observation of the nano-scale particles in geogas matters and its geological significance显示文摘The geogas collectors showing a geogas anomaly in field geogas prospecting and in simulation tests were selected for the observation under high resolution microscopy. The result demonstrates that the geogas matter is transported in the form of nano scale particles with a size of about \%N\% nm to \%N\%·10 nm, and accumulated into aggregations of 1\2 μm to \%N\%·10 μm, with globular and film shape, and the component of Cu, Zn, Cr, Au, Al, V, Si, Br, Cl, S, Ca, etc. Based on the knowledge of nano science and technique, the mechanism of the geogas prospecting and its significance in geology and mineral prospecting are discussed. | 童纯菡 李巨初 葛良全 杨凤根 | 1998 | Science China Earth Sciences1998，41，3： | 15 |
| 7 | Analysis on the decadal scale variation of the dust storm in North China显示文摘In this paper, the temporal variation characteristics of the dust storm in North China are investigated. Based on power spectrum analysis and wavelet analysis, 1956-1970 and 1985-1999 are chosen as the high-frequency and low-frequency dust storm decades respectively. Analysis results clearly show that the spring and wintertime anomalous atmospheric circulation between these two dec-ades are significantly different. Compared with the former decade, there are a strengthened polar vortex, enhanced westerlies near 50°N, and a weak East Asian major though in the winter of the latter decade. The north and center parts of the Siberian high and the Aleutian low become weak. The southerly and easterly wind anomalies appear over the north and east parts of China, which implies the weakening of East Asian winter monsoon. Meanwhile, northern China experiences warmer winters and wetter springs, which are in favor of the weakening of dust storm intensity in North China. There are significant out-of-phase relationships between dust frequency and wintertime westerly intensity, as well as between dust frequency and Arctic Oscillation. It is also found that the frequency of dust weather is strongly re-lated to winter-springtime East Asian monsoon intensity. | KANG Dujuan1,2 & WANG Huijun1 1.

| 8 | The effect of nursing intervention based on Autar scale results to reduce deep venous thrombosis incidence in orthopaedic surgery patients显示文摘Purpose:To reduce the incidence of deep venous thrombosis(DVT)with nursing intervention based on the Autar DVT risk assessment scale among orthopaedic surgery patients.Methods:We recruited 216 orthopaedic surgery patients at our hospital between September 2013 and March 2014.The patients were assigned to intervention and historical control groups based on the time of admission.Using the Autar DVT risk assessment scale,we assessed the DVT risk levels in both groups;the intervention group received the corresponding prophylactic measures while the control group received routine nursing.Results:The DVT incidence rate and the D-dimer level on postoperative day 3 in the intervention group were lower(1.82%;623±225 mg/L,respectively)than that of the control group(9.43%;825±201 mg/L,respectively);both differences were statistically significant(p<0.05).Conclusions:The Autar scale is beneficial when used in orthopaedic surgery patients;corresponding nursing intervention based on Autar scale assessment can prevent DVT effectively. | Hui-Zhen Yin Ci-Ming Shan | 2015 | International Journal of Nursing Sciences2015，2，2： | 14 |
| 9 | Mapping global impervious surface area and green space within urban environments显示文摘The mapping of impervious surface area(ISA) and urban green space(UGS) is essential for improving the urban environmental quality toward ecological, livable, and sustainable goals. Currently, accurate ISA and UGS products are lacking in urban areas at the global scale. This study established regression models that estimated the fraction of ISA/UGS in global 30 cities for validation using MODIS NDVI and DMSP/OLS nighttime light imageries. A global dataset of ISA and UGS fraction with a spatial resolution of 250 m×250 m was developed using the regression model, with a mean relative error of 0.19 for its ISA. The results showed the global urban area of 76.29×10~4 km^2, which was primarily distributed in central Europe, eastern Asia,and central and eastern North America. The urban land area in North America, Europe, and Asia was 66.3×10~4 km^2, accounting for 86.91% of the world’s urban area;the urban land area of the top 50 countries accounted for 59.32% of the total urban land area in the world. The global ISA of 45.26×10~4 km^2 was mainly distributed in central and southern North America, eastern Asia, and Europe, as well as coastal regions around the world. The proportion of ISA situated in built-up areas on the continental scale followed the order of Africa(>70%)>South America>Oceania>Asia(>60%)>North America>Europe(>50%), and these areas were mostly in southeastern North America, southwestern Europe, and eastern and western Asia. North America, Europe, and Asia accounted for 89.44% of the world’s total UGS. The cities of developed countries in Europe and North America exposed a dramatic mosaic of ISA and UGS composites in urban construction. Therefore, the proportion of UGS is relatively high in those cities. However, in developing and underdeveloped countries, the proportion of UGS in built-up areas is relatively low, and urban environments need to be improved for livability. | Wenhui KUANG | 2019 | Science China Earth Sciences2019，62，10： | 12 |
| 10 | Scale effect of Planck's law over nonisothermal blackbody surface显示文摘Many physical laws, principles, models, measurement methods, etc., are applicable only to either a point on surface or a homogeneous surface. However, remote sensing deals with pixels which may range from meters to kilometers. Therefore scale effects of these laws and measurements are inevitable problems which must be faced. As an example, the spatial scale effect of Planck Law over nonisothermal blackbody surface is considered. | 李小文 王锦地 A. H. Strahler | 1999 | Science China(Technological Sciences)1999，42，6： | 12 |
| 11 | Electro-acupuncture Treatment for Internet Addiction: Evidence of Normalization of Impulse Control Disorder in Adolescents显示文摘Objective: To observe the impacts of electro-acupuncture(EA) and psychological intervention(PI) on impulsive behavior among internet addiction(IA) adolescents. Methods: Thirty-two IA adolescents were allocated to either EA(16 cases) or PI(16 cases) group by a randomized digital table. Subjects in the EA group received EA treatment and subjects in the PI group received cognition and behavior therapy. All adolescents underwent 45-d intervention. Sixteen healthy volunteers were recruited into a control group. Barratt Impulsiveness Scale(BIS-11) scores, Young's Internet Addiction Test(IAT) as well as the ratio of brain N-acetyl aspartate(NAA) to creatine(NAA/Cr) and choline(Cho) to creatine(Cho/Cr) were recorded by magnetic resonance spectroscopy before and after intervention respectively. Results: The IAT scores and BIS-11 total scores in both EA and PI group were remarkably decreased after treatment(P<0.05), while EA group showed more significant decrease in certain BIS-11 sub-factors(P<0.05). Both NAA/Cr and Cho/Cr were significantly improved in EA group after treatment(P<0.05); however, there were no significant changes of NAA/Cr or Cho/Cr in PI group after treatment(P>0.05). Conclusions: Both EA and PI had significantly positive effect on IA adolescents, especially in the aspects of psychological experiences and behavioral expressions, EA might have an advantage over PI in terms of impulsivity control and brain neuron protection. The mechanism underlying this advantage might be related to the increased NAA and Cho levels in prefrontal and anterior cingulate cortices. | YANG Yang LI Hui CHEN Xi-xi ZHANG Luo-ming HUANG Bing-jie ZHU Tian-min | 2017 | Chinese Journal of Integrative Medicine2017，23，11： | 11 |
| 12 | 中国城市绿色发展效率时空演变特征及影响因素显示文摘To resolve conflicts between development and the preservation of the natural environment,enable economic transformation,and achieve the global sustainable development goals(SDGs),green development(GD)is gradually becoming a major strategy in the construction of an ecological civilization and the ideal of building a'beautiful China',alongside the transformation and reconstruction of the global economy.Based on a combination of the concept and implications of GD,we first used the Slacks Based Model with undesirable outputs(SBM-Undesirable),the Theil index,and the spatial Markov chain to measure the spatial patterns,regional differences,and spatio-temporal evolution of urban green development efficiency(UGDE)in China from 2005 to 2015.Second,by coupling natural and human factors,the mechanism influencing UGDE was quantitatively investigated under the framework of the human-environment interaction.The results showed that:(1)from 2005 to 2015,the UGDE increased from 0.475 to 0.523,i.e.,an overall increase of 10%.In terms of temporal variation,there was a staged increase,with its evolution having the characteristics of a'W-shaped'pattern.(2)The regional differences in UGDE followed a pattern of eastern>central>western.For different types of urban agglomeration,the UGDE had inverted pyramid cluster growth characteristics that followed a pattern of'national level>regional level>local level',forming a stable hierarchical scale structure of'super cities>mega cities>big cities>medium cities>small cities'.(3)UGDE in China has developed with significant spatial agglomeration characteristics.High-efficiency type cities have positive spillover effects,while low-efficiency cities have negative effects.Different types of urban evolution processes have a path dependence,and a spatial club convergence phenomenon exists,in which areas with high UGDE are concentrated and drive low UGDE elsewhere.(4)Under the framework of regional human-environment interaction,the degree of human and social influence on UGDE is greater than that of the natural background.The economic strength,industrial structure,openness,and climate conditions of China have positively promoted UGDE. | 周亮 周成虎 车磊 王宝 | 2020 | Journal of Geographical Sciences2020，30，5： | 11 |

| 14 | Soil erosion and sediment transport in the gullied Loess Plateau:Scale effects and their mechanisms显示文摘Scale effects exist in the whole process of rainfall―runoff―soil erosion―sediment transport in river basins.The differences of hydrographs and sediment graphs in different positions in a river basin are treated as basic scale effects,which are more complex in the gullied Loess Plateau,a region notorious for high intensity soil erosion and hyper-concentrated sediment-laden flow.The up-scaling method of direct extrapolation that maintains dynamical mechanism effective in large scale application was cho-sen as the methodology of this paper.Firstly,scale effects of hydrographs and sediment graphs were analyzed by using field data,and key sub-processes and their mechanisms contributing to scale effects were clearly defined.Then,the Digital Yellow River Model that integrates sub-models for the sub-processes was used with high resolution to simulate rainfall―runoff―soil erosion―sediment transport response in Chabagou watershed,and the distributed results representing scale effects were obtained.Finally,analysis on the simulation results was carried out.It was shown that gravitational erosion and hyper-concentrated flow contribute most to the spatial variation of hydrographs and sediment graphs in the spatial scale.Different spatial scale distributions and superposition of different sub-processes are the mechanisms of scale effects. | LI TieJian1,WANG GuangQian1,XUE Hai2,3 & WANG Kai4 1 State Key Laboratory of Hydroscience and Engineering,Tsinghua University,Beijing 100084,China 2 Yellow River Engineering Consulting Co.,Ltd.,Zhengzhou 450003,China 3 North China Institute of Water Conservancy and Hydropower,Zhengzhou 450008,China 4 China Institute of Water Resources and Hydropower Research,Beijing 100038,China | 2009 | Science China(Technological Sciences)2009，52，5： | 11 |
| 15 | On characteristic modeling of a class of flight vehicles'attitude dynamics显示文摘The characteristic modeling problem of flight vehicles'attitude dynamics is considered in this paper.In terms of the affine nonlinear system with triangle form of flight vehicles'attitude dynamics,a general method is presented to compress the dynamics into the characteristic model parameters,by introducing the time scale of nonlinear systems and a class of system states related compress functions.The parameter region and limit of the characteristic model are also given.From the given parameter region it is seen that the bound of the characteristic model parameters is dependent on the sampling period,the modeling error,the system order and the system change rate.The modeling error of the established characteristic model can be arbitrarily small according to the control precision,showing the difference between the characteristic model and other model reduction methods,that is,no system information is lost using this approach.On the basis of this modeling approach,the characteristic model of the flexible satellite attitude is established,as well as the bound and limit of the parameters,which sets a theoretical foundation for characteristic model based control design of flight vehicles. | MENG Bin &WU HongXin National Laboratory of Space Intelligent Control,Beijing Institute of Control Engineering,Beijing 100190,China | 2010 | Science China(Technological Sciences)2010，53，8： | 11 |

| 20 | A study of scale effect on specific sediment yield in the Loess Plateau,China显示文摘Based on data from 148 hydrometric stations in the Yellow River Basin, an analysis of regional scale relationship, or the relationship between specific sediment yield and drainage basin area, has been undertaken in the study area of the Loess Plateau. For different regions, scale relationship in log-log ordinate can be fitted by two types of lines: straight and parabola, and for each line, a function was fitted using regression analysis. The different scale relationships have been explained in terms of the difference in surface material distribution and landforms. To offset the scale-induced influence, calcu-lation has been done based on the fitted functions, in order to adjust the data of specific sediment yield to a common standard area. Based on the scaled data, a map of specific sediment yield was con-structed using Kriging interpolation. For comparison, a map based on the un-scaled data of specific sediment yield was also constructed using the same method. The two maps show that the basic pattern of specific sediment yield was basically the same. The severely eroded areas (Ys >10000 t km-2a-1) were at the same locations from Hekouzhen to Longmen in the middle Yellow River Basin. However, after the adjustment to a common standard area, the very severely eroded area (Ys >20000 t km-2a-1) became much enlarged because after the adjustment, all the values of Ys in the lower river basin in those regions became much larger than before. | YAN YunXia & XU JiongXin Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences Key Laboratory of Water Cycle and Related Land Surface Processes, Chinese Academy of Sciences, Beijing 100101, China | 2007 | Science China Earth Sciences2007，50，1： | 9 |
