| 1 | Stenting for symptomatic intracranial arterial stenosis in China:1-year outcome of a multicentre registry study显示文摘background and purpose A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis(ICAS)combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable.However,it remained uncertain whether the low event rate could be of a long term.We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Methods Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid,middle cerebral,intracranial vertebral or basilar arteries combined with poor collaterals were enrolled.Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators.The primary outcome was the rate of 30-day stroke,transient ischaemic attack and death,and 12-month ischaemic stroke within the same vascular territory,haemorrhagic stroke and vascular death after stenting.results From September 2013 to January 2015,300 patients(ages 58.3±9.78 years)were recruited.Among them,159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent.During the 1-year follow-up,25 patients had a primary end point event.The probability of primary outcome at 1 year was 8.1%(95% CI 5.3% to 11.7%).In 76 patients with digital subtraction angiography follow-up,27.6%(21/76)had re-stenosis≥50% and 18.4%(14/76)had re-stenosis≥70%.No baseline characteristic was associated with the primary outcome.Conclusion The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Further randomised trial of comparing individually tailored stenting with best medical therapy is needed. | Ning Ma Yong Zhang Jie Shuai Changchun Jiang Qiyi Zhu Kangning Chen Li Liu Baomin Li Xiangqun Shi Lianbo Gao Yajie Liu Feng Wang Yongli Li Tieyan Liu Hongbo Zheng Dapeng Mo Feng Gao Yilong Wang Yongjun Wang Lei Feng Zhongrong Miao | 2018 | Stroke & Vascular Neurology2018，3，3： | 29 |
| 2 | Super-hydrophobic characteristics of butterfly wing surface显示文摘Many biological surface are hydrophobic because of their complicated composition and surface microstructure. Eleven species (four families) of butterflies were selected to study their micro-, nano-structure and super-hydrophobic characteristic by means of Confocal Light Microscopy, Scanning Electron Microscopy and Contact Angle Measurement. The contact an- gles of water droplets on the butterfly wing surface were consistently measured to be about 150 ? and 100 ? with and without the squamas, respectively. The dust on the surface can be easily cleaned by moving spherical droplets when the inclining angle is larger than 3 ?. It can be concluded that the butterfly wing surface possess a super-hydrophobic, water-repellent, self-cleaning, or “Lotus-effect”characteristic. The contact angle measurement of water droplets on the wing surface with and without the squamas showed that the water-repellent characteristic is a consequence of the microstructure of the squamas. Each water droplet (diameter 2 mm) can cover about 700 squamas with a size of 40 m×80 m of each squama. The regular riblets with a width of 1000 nm to 1500 nm are clearly observed on each single squama. Such nanostructure should play a very important role in their super-hydrophobic and self-cleaning characteristic. | CONG Qian, CHEN Guang-hua, FANGYan , REN Lu-quan Key Laboratory for Terrain-Machine Bionics Engineering (Ministry of Education, China), Jilin University, Changchun, 130022, P.

| 5 | Hydrology and water resources variation and its response to regional climate change in Xinjiang显示文摘Based on the surface runoff, temperature and precipitation data over the last 50 years from eight representative rivers in Xinjiang, using Mann-Kendall trend and jump detection method, the paper investigated the long-term trend and jump point of time series, the surface runoff, mean annual temperature and annual precipitation. Meanwhile, the paper analyzed the relationship between runoff and temperature and precipitation, and the flood frequency and peak flow. Results showed that climate of all parts of Xinjiang conformably has experienced an increase in temperature and precipitation since the mid-1980s. Northern Xinjiang was the area that changed most significantly followed by southern and eastern Xinjiang. Affected by temperature and precipitation variation, river runoff had changed both inter-annually and intra-annually. The surface runoff of most rivers has increased significantly since the early 1990s, and some of them have even witnessed the earlier spring floods, later summer floods and increasing flood peaks. The variation characteristics were closely related with the replenishment types of rivers. Flood frequency and peak flow increased all over Xinjiang. Climate warming has had an effect on the regional hydrological cycle. | XU Changchun CHEN Yaning YANG Yuhui HAO Xingming SHEN Yongping | 2010 | Journal of Geographical Sciences2010，20，4： | 17 |
| 6 | Laser probe ^(40)Ar/^(39)Ar dating of mica on the deformed rocks from Altyn Fault and its tectonic implications,western China显示文摘The samples of Caledonian mylonitized granite and Jurassic meta-sedimentary rocks were collected in the north of Dangjinshan Pass, Qaidam gate fault-valley and Gesi fault-valley. Detailed studies under the microscope and electronic microscope suggest that all the samples contain the syntectonic-growing minerals such as white mica, chlorite, sericite, biotite, etc. By dating these minerals, we got a group of 40Ar/39Ar laser probe isochronal ages of 89-92 Ma and apparent ages of (46.6±6.4) Ma. The ages ranging from 97 to 46 Ma were reported for the first time in the isotopic dating researches of the Altyn Fault The isochronal age group of (98-89) Ma indicates that a ductile strike-slip event, with low-grade metamorphism, began in late Cretaceous. This suggests that the strike-slip movement of the Altyn Fault should be related to the formation of the so-called west tectonic syntaxis in the Nepal-western Kunlun area. | LIU Yongjiang, YE Huiwen, GE Xiaohong, CHEN Wen, LIU Junlai, REN Shoumai & PAN HongxunCollege of Earth Sciences, Changchun University of Science and Technology, Changchun 130061, China Graduate School, China University of Geosciences, Beijing 100083, China Laboratory of Isotopic Geochronology, Institute of Geology, Ministry of Land and Resources of China, Beijing 100037, China | 2001 | Chinese Science Bulletin2001，46，4： | 16 |
| 7 | The research progress on lateral shift of reflected electromagnetic wave at the interface of two conductive media显示文摘In this paper the research status of lateral shift of reflected electromagnetic wave at the interface of conductive media was reviewed, the lateral shift and the lateral delay were analyzed, and the charac-teristic of lateral shift curves varying with the angle of incidence was introduced in detail. For electro-magnetic wave logging, the error correction method of lateral shift was stressed in this paper, the magnitude of measured errors caused by the lateral shift was established. It is noticed that the longer wavelength, the larger error of measured results. With respect to the effect of lateral shift, the problem which still needs to be settled in the measurement of electromagnetic wave, as well as prospects on the further research and applications of lateral shift are described. | LIU FuPing WANG AnLing CHEN Qiang LI RuiZhong CHEN HuiGuo YANG ChangChun | 2008 | Chinese Science Bulletin2008，53，7： | 15 |
| 8 | Geologic investigation and mapping of the Sinus Iridum quadrangle from Clementine, SELENE, and Chang’e-1 data显示文摘The objectives of lunar satellite remote sensing are to study lunar surface characteristics, inner structure, and its evolution history. The contents of TiO 2 and FeO are assessed from Clementine UV/VIS data for Sinus Iridum. The geologic stratigraphic units and crates are interpreted visually based on SELENE Terrain Camera (TC) images and the spatial resolution of which is up to 10 m. And the geologic ages of different stratigraphic units are calculated by the crater size-frequency distributions measurements. The gravity anomaly is generated from SELENE gravity model (SGM90d) to show its difference from Mare Imbrium. Furthermore, the thickness of lunar regolith is also derived from microwave radiometer data of Chang’e-1 satellite. Integrating these results, it shows that the Sinus Iridum is different from the Mare Imbrium in inner structure and surface sedimentation. And its history of subsidence, deposition, volcanism, and impact is described. It makes sense to the future soft-landing and sampling at potential Sinus Iridum by remote sensing geologic analysis. | CHEN ShengBo , MENG ZhiGuo, CUI TengFei, LIAN Yi, WANG JingRan & ZHANG XuQing College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 10 |
| 9 | Sliding resistance of plates with bionic bumpy surface against soil显示文摘The non-smooth surface morphology of dung beetle, Copris ochus, was analyzed. The bulldozing plates with bionic geometric non-smooth or the chemical uneven surface were designed for the soil sliding test based on the simulation of the bumpy surface of the dung beetle. Special black metals— with different contents of alloys of manganese, silicon, chromium, copper and rare earth— were developed for making geometric non-smooth and chemical uneven surfaces by means of surface welding at the surfaces of a middle carbon steel plate. Four metals, with different surface properties including hardness and water contact angle were used to make the bulldozing plates for measuring the soil sliding resistance. Test results of soil sliding resistance indicate that all the geometric non-smooth plates and the chemical uneven plates reducing soil friction. Considering the materials and surface morphology, the bionic plate can reduce the soil sliding resistance from 18.1 % up to 42.2%, compared to the traditional smooth bulldozing plate made from middle carbon steel. The test results also show that the smaller the normal load, the greater effect on resistance reduction by the bionic non-smooth surface plates. | LI Jian-qiao1, SUN Jiu-rong2, REN Lu-quan1, CHEN Bing-cong1 1.

| 13 | The Effect of Tide on the Global Climate Change显示文摘The differential rotation between the solid and fluid spheres caused by tidal force could explain the 1500 to 1800-year cycle of the world's temperature. Strong tide increases the vertical and horizontal mixing of water in the oceans, drawing the cold Pacific water from the depths to the surface and the warm water from the west to the east, where it cools or warms the atmosphere above, absorbs or releases CO2 to decrease or increase greenhouse effect and to make La Nina or El Nino occur in the global. The moon's declination and obliquity of the ecliptic affect the tidal intensity. The exchange of tidal energy and tide-generating force caused by the sun, moon and major planets makes the earth's layers rotate in different speeds. The differenti-al rotation between solid and fluid of the earth is the basic reason for El Nino and global climate change. | YANG Xuexiang, CHEN Zhen and CHEN Dianyou( College of Ceo - exploration Science and Technology, Jilin University, Changchun 130026, P.

| 14 | The fluxes and controlling factors of N_2O and CH_4 emissions from freshwater marsh in Northeast China显示文摘Nitrous oxide (N2O) and methane (CH4) emissions were measured using a static chamber method in two adjacent plots of freshwater marsh predominated by Calamagrostis angustifolia, one is seasonal waterlogged (SW) and the other without surface water accumulation (NW), in Sanjiang Plain wetland (47°35′N, 133°31′E), northeast China, during 2002-2004. The diurnal and seasonal flux variations of both gases were significantly correlated with 5-cm-soil temperature. The NW marsh is a source of N2O and sink of CH4, while the SW marsh is sink of N2O and source of CH4. Remarkably, we observed a N2O emission peak under Eh of +300 to +100 mV, and CH4 emission peak under Eh of +300 to +400 mV, which indicate additional sources of N2O and CH4 for the freeze-thaw induced emission peaks of N2O and CH4 observed between late July and early August. Further study shows that the additional N2O and CH4 were emitted under the frozen soil after thawing. | YU JunBao1,2, LIU JingShuang2, SUN ZhiGao1, SUN WeiDong3, WANG JinDa2, WANG GuoPing2 & CHEN XiaoBing1 1 Key Lab of Coastal Envionment Processed, Yantai Institute of Coastal Zone Research for Sustainable Development, Chinese Academy of Sciences, Yantai 264003, China 2 Key Lab of Wetland Ecology and Environment, Northeast Institute of Geography and Agricultural Ecology, Chinese Academy of Sciences, Changchun 130012, China 3 Key Laboratory of Isotope Geochronology and Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China | 2010 | Science China Earth Sciences2010，53，5： | 7 |
| 15 | Factors impacting nanoindentation testing results of the cuticle of dung beetle Copris ochus Motschulsky显示文摘The cuticle of dung beetle is a layered composite material in micro- or nano-scale. Dung beetle can fly, walk and dig. It can shovel and compact dung of mammals into balls. It use foreleg to walk, midleg and hindleg to hold and impel dung ball. Its two foreleges as digging legs are developed. The factors impacting the nanoindentation testing results of the femur cuticle of forelegs of dung beetle Copris ochus Motschulsky were examined. The nanomechanical test instrument used for the tests was Hysitron nanomechanical system. The results shown that the holding time and loading time are important factors im- pacting the accuracy of such indentation properties as reduced modulus (Er) and the harness ( H ) of the femur cuticle of the forelegs of dung beetle Copris ochus Motschulsky in nanoscale. There exists a threshold holding time of 20 s for the reduced modulus of the femur cuticle. The tests of nanoindentation creep property and the regression analysis of relationship between the depth increment at the maximum load and the time further confirmed the correction of the above threshold holding time. There exist visco-elastic-plastic behaviour and creep phenomenon in the femur cuticle during indenting. Its creep property during the holding procedure at maximum load can be regressed by a general logarithmic equation. The equation fitted by the testing data is ? h = 54.83452 ln(0.00723t +1.00486), where, ? h is the depth increment at the maximum load and t is the time. | TONG Jin , SUN Ji-yu , CHEN Dong-hui , ZHANG Shu-jun 1 1 1 2 1.

| 16 | Detection and characterization of diverse alpha-and betacoronaviruses from bats in China显示文摘Bats have been implicated as important reservoir hosts of alpha- and betacoronaviruses. In this study, diverse coronaviruses(CoVs) were detected in 50 of 951(positive rate 5.3%) intestinal specimens of eight bat species collected in four provinces and the Tibet Autonomous Region of China by pan-coronavirus RT-PCR screening. Based on 400-nt RNA-dependent RNA polymerase(Rd RP) sequence analysis, eight belonged to genus Alphacoronavirus and 42 to Betacoronavirus.Among the 50 positive specimens, thirteen gave rise to CoV full-length Rd RP gene amplification for further sequence comparison, of which three divergent sequences(two from a unreported province) were subjected to full genome sequencing. Two complete genomes of betacoronaviruses(JTMC15 and JPDB144) and one nearly-complete genome of alphacoronavirus(JTAC2) were sequenced and their genomic organization predicted. The present study has identified additional numbers of genetically diverse bat-borne coronaviruses with a wide distribution in China. Two new species of bat CoV, identified through sequence comparison and phylogenetic analysis, are proposed. | Lin Xu Fuqiang Zhang Weihong Yang Tinglei Jiang Guanjun Lu Biao He Xingyu Li Tingsong Hu Gang Chen Yun Feng Yuzhen Zhang Quanshui Fan Jiang Feng Hailin Zhang Changchun Tu | 2016 | Virologica Sinica2016，31，1： | 6 |
| 17 | Correlation between echolocation calls and morphological features among three kinds of bats显示文摘The correlation between echolocation sound and morphological features of 18 species of bats, which are subordinated to 3 families including rhinolophidae, hipposideridae and vespertilionidae is studied. Pearson's correlation and regression analysis are adopted to analyze the correlations between noseleaf width (NW) and forearm length (FAL), NW and dominant frequency (DF), FAL and DF. The results show a positive correlation between NW and FAL and a negative correlation between NW and DF in Rhinolophidae. In each family, there is a negative correlation between FAL and DF. Some species have a higher or lower frequency than predicted one according to their body size. There are significant differences of the regression equation of FAL and DF among the three families. For the bats with the same body size, the order in frequency is: hipposiderid bats> rhinolophid bats> vespertilionid bats. The mechanism of interrelationship between FAL and DF of bats, the reason why these deviations occur in correlativity of the three families and the mechanism of the interaction between morphological, physiological and ecological characteristics are discussed. | FENG Jiang , CHEN Min, LI Zhenxin, ZHANG Shuyi, ZHAO Huihua and ZHOU Jiang(1.

| 18 | Adaptive changes of gastro-entero-pancreatic system endocrine cells in the black-spotted pond frog Rana nigromaculata after fasting显示文摘Changes in distribution density,morphology and secretory content of endocrine cells in the gastro-entero-pancreatic system of black-spotted frogs Rana nigromaculata before and after fasting were investigated using immunohistochemistry and antisera to six gut hormones.Six types of endocrine cells were detected in the digestive tract of Rana nigromaculata,including 5-hydroxytryptamine(5-HT),gastrin(GAS),somatostatin(SOM),glucagon(GLU),pancreatic polypeptide(PP)and vasoactive intestinal polypeptide(VIP)cells.After fasting,the density of 5-HT cells in the esophagus,cardia and fundus,GAS cells in the fundus and pylorus,PP cells in the fundus decreased significantly(P<0.01),while SOM cells in the cardia,GLU cells in the rectum increased significantly(P<0.01).The cytoplasmic processes of 5-HT cells became shorter or not detectable.The secretory content of GAS cells reduced in the cardia.The positive immunostaining reaction in the perinuclear region of SOM cells in the cardia,fundus and pylorus became weaker,while the staining intensity in the periphery of these cells became stronger.VIP cells were not detectable in the whole digestive tract after fasting.Five types of endocrine cells were found in the pancreas of Rana nigromaculata,including 5-HT,GAS,SOM,GLU and PP cells.After fasting,the density of 5-HT cells decreased slightly(P>0.05),while SOM,GAS,GLU and PP cells increased significantly(P<0.01).Furthermore,the secretory content of GLU cells increased significantly.Considering their functionalities,our results indicate that the changes of GEP endocrine cells in Rana nigromaculata responded adaptively to starvation-induced stress. | Hongzhen PAN Honghong CHEN Lianjiu ZHU Yang LI Changchun LI Shengzhou ZHANG | 2009 | Current Zoology2009，55，4： | 4 |
| 19 | Research on water ice content in Cabeus crater using the data from the microwave radiometer onboard Chang’e-1 satellite显示文摘The existence, formation and content of water ice in the lunar permanently shaded region is one of the important questions for the current Moon study. On October 9, 2009, the LCROSS mission spacecraft impacted the Moon, and the initial result verified the existence of water on the Moon. But the study on formation and content of water ice is still under debate. The existence of water ice can change the dielectric constants of the lunar regolith, and a microwave radiometer is most sensitive to the dielectric parameters. Based on this, in this paper, the radiation transfer model is improved according to the simulation results in high frequency. Then the mixture dielectric constant models, including Odelevsky model, Wagner and landau-Lifshitz model, Clau-sius model, Gruggeman-Hanai model, etc., are analyzed and compared. The analyzing results indicate that the biggest difference occurs between Lichtenecker model and the improved Dobson model. The values estimated by refractive model are the second biggest in all the models. And the results from Odelevsky model, strong fluctuation model, Wagner and Landau –Lifshitz model, Clausius model and Bruggeman-Hanai model are very near to each other. Thereafter, the relation between volume water ice content and microwave brightness temperature is constructed with Odelevsky mixing dielectric model and the improved radiative transfer simulation, and the volume water ice content in Cabeus crater is retrieved with the data from microwave radiometer onboard Chang’e-1 satellite. The results present that the improved radiative transfer model is proper for the brightness temperature simulation of the one infinite regolith layer in high frequency. The brightness temperature in Cabeus crater is 69.93 K (37 GHz), and the corresponding volume water ice content is about 2.8%. | MENG ZhiGuo 1 , CHEN ShengBo 1* , Edward Matthew OSEI Jnr 2 , WANG ZiJun 1 & CUI TengFei 1 1 College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China 2 Department of Geomatic Engineering, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 4 |
| 20 | Trends in sunshine duration and atmospheric visibility in the Yunnan-Guizhou Plateau,1961-2005显示文摘Using the observed data from 184 stations over the Yunnan-Guizhou Plateau (YGP) from 1961 to 2005,the long-term trends in sunshine duration,cloud amount,dry visibility (Vd),dry extinction,and water vapor over the YGP are analyzed.The results show that 85% of the stations recorded shortening annual sunshine duration,with the decrease rates between -12.2 and -173.7 h/10yr.Results of Mann-Kendall tests indicate that,among the stations with decreasing sunshine duration,63.7% of them experienced an abrupt change that started in the 1970s and peaked in the 1980s.This decreasing trend has reversed in the early years of the 21st century.The cloud cover and water vapor content in the mid and lower levels over the YGP had no obvious changes during the study period.The annual averages of Vd declined from 34 km in the 1960s to 27 km at present.The annual mean dry extinction coefficient trended upward,from 0.176 to 0.190,on the YGP from 1980 to 2005.Analyses of cloud cover,water vapor,atmos-pheric visibility,and dry extinction coefficient revealed that emitted tropospheric aerosols (including air pollutants) resulting from increased energy consumption over the YGP could be a major factor influencing the reductions of sunshine duration and atmospheric visibility. | XiaoBo Zheng TianLiang Zhao YuXiang Luo ChangChun Duan Juan Chen | 2011 | Research in Cold and Arid Regions2011，3，2： | 4 |
