2Loess in the Tian Shan and its implications for the development of the Gurbantunggut Desert and drying of northern Xinjiang显示文摘Eolian loess is widely distributed on the various geomorphic surfaces between 700-2400 m a.s.l. on the northern slope of the Tian Shan. It is formed in a synchronous manner with dust transported from the Gurbantunggut Desert in the Junggar Basin. The thickest section of loess was found in the Shawan and Shihezi regions. Paleomagnetic and climatic proxy analyses of over 71 m of a loess-paleosol sequence on the highest terrace of the Qingshui He (River) in the Shawan show that the paleomagnetic Bruhues/Matuy-ama (B/M) boundary lies at the bottom of paleosol S8, at a depth of 69.5 m, and the bottom of the sequence was estimated to be -0.8 Ma. This implies that the extremely dry climatic conditions in the Junggar Basin and the initial Gurbantunggut Desert were present at least by 0.8 Ma. High-resolution grain size series demonstrate that this area and desert expansion experienced two dramatic periods of desert expansions that occurred at -0.65 Ma and 0.5 Ma, respectively; and the subsequent continuousFANG Xiaomin SHI Zhentao YANG Shengli YAN Maodu LI Jijun JIANG Ping’an 2002Chinese Science Bulletin2002,47,16:33

4Paleozoic and Mesozoic Basement Magmatisms of Eastern Qaidam Basin,Northern Qinghai-Tibet Plateau:LA-ICP-MS Zircon U-Pb Geochronology and its Geological Significance显示文摘The eastern margin of the Qaidam Basin lies in the key tectonic location connecting the Qinling,Qilian and East Kunlun orogens.The paper presents an investigation and analysis of the geologic structures of the area and LA-ICP MS zircon U-Pb dating of Paleozoic and Mesozoic magmatisms of granitoids in the basement of the eastern Qaidam Basin on the basis of 16 granitoid samples collected from the South Qilian Mountains,the Qaidam Basin basement and the East Kunlun Mountains.According to the results in this paper,the basement of the basin,from the northern margin of the Qaidam Basin to the East Kunlun Mountains,has experienced at least three periods of intrusive activities of granitoids since the Early Paleozoic,i.e.the magmatisms occurring in the Late Cambrian(493.1±4.9 Ma),the Silurian(422.9±8.0 Ma-420.4±4.6 Ma) and the Late Permian-Middle Triassic(257.8±4.0 Ma-228.8±1.5 Ma),respectively.Among them,the Late Permian-Middle Triassic granitoids form the main components of the basement of the basin.The statistics of dated zircons in this paper shows the intrusive magmatic activities in the basement of the basin have three peak ages of 244 Ma(main),418 Ma,and 493 Ma respectively.The dating results reveal that the Early Paleozoic magmatism of granitoids mainly occurred on the northern margin of the Qaidam Basin and the southern margin of the Qilian Mountains,with only weak indications in the East Kunlun Mountains.However,the distribution of Permo-Triassic(P-T) granitoids occupied across the whole basement of the eastern Qaidam Basin from the southern margin of the Qilian Mountains to the East Kunlun Mountains.An integrated analysis of the age distribution of P-T granitoids in the Qaidam Basin and its surrounding mountains shows that the earliest P-T magmatism(293.6-270 Ma) occurred in the northwestern part of the basin and expanded eastwards and southwards,resulting in the P-T intrusive magmatism that ran through the whole basin basement.As the Cenozoic basement thrust system developed in the eastern Qaidam Basin,the nearly N-S-trending shortening and deformation in the basement of the basin tended to intensify from west to east,which went contrary to the distribution trend of N-S-trending shortening and deformation in the Cenozoic cover of the basin,reflecting that there was a transformation of shortening and thickening of Cenozoic crust between the eastern and western parts of the Qaidam Basin,i.e.,the crustal shortening of eastern Qaidam was dominated by the basement deformation(triggered at the middle and lower crust),whereas that of western Qaidam was mainly by folding and thrusting of the sedimentary cover(the upper crust).CHEN Xuanhua George GEHRELS YIN An LI Li JIANG Rongbao 2012Acta Geologica Sinica(English Edition)2012,86,2:32
5Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot.Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu 2020Burns & Trauma2020,8,1:34

7Laparoscopic vs open D2 gastrectomy for locally advanced gastric cancer: A meta-analysis显示文摘AIM:To conduct a meta-analysis comparing laparoscopic(LGD2)and open D2 gastrectomies(OGD2)for the treatment of advanced gastric cancer(AGC).METHODS:Randomized controlled trials(RCTs)and non-RCTs comparing LGD2 with OGD2 for AGC treatment,published between 1 January 2000 and 12January 2013,were identified in the Pub Med,Embase,and Cochrane Library databases.Primary endpoints included operative outcomes(operative time,intraoperative blood loss,and conversion rate),postoperative outcomes(postoperative analgesic consumption,time to first ambulation,time to first flatus,time to first oralintake,postoperative hospital stay length,postoperative morbidity,incidence of reoperation,and postoperative mortality),and oncologic outcomes(the number of lymph nodes harvested,tumor recurrence and metastasis,disease-free rates,and overall survival rates).The Cochrane Collaboration tools and the modified Newcastle-Ottawa scale were used to assess the quality and risk of bias of RCTs and non-RCTs in the study.Subgroup analyses were conducted to explore the incidence rate of various postoperative morbidities as well as recurrence and metastasis patterns.A Begg’s test was used to evaluate the publication bias.RESULTS:One RCT and 13 non-RCTs totaling 2596patients were included in the meta-analysis.LGD2 in comparison to OGD2 showed lower intraoperative blood loss[weighted mean difference(WMD)=-137.87 m L,95%CI:-164.41--111.33;P<0.01],lower analgesic consumption(WMD=-1.94,95%CI:-2.50--1.38;P<0.01),shorter times to first ambulation(WMD=-1.03d,95%CI:-1.90--0.16;P<0.05),flatus(WMD=-0.98d,95%CI:-1.30--0.66;P<0.01),and oral intake(WMD=-0.85 d,95%CI:-1.67--0.03;P<0.05),shorter hospitalization(WMD=-3.08 d,95%CI:-4.38--1.78;P<0.01),and lower postoperative morbidity(odds ratio=0.78,95%CI:0.61-0.99;P<0.05).No significant differences were observed between LGD2 and OGD2 for the following criteria:reoperation incidence,postoperative mortality,number of harvested lymph nodes,tumor recurrence/metastasis,or three-or five-year diseasefree and overall survival rates.However,LGD2 had longer operative times(WMD=57.06 min,95%CI:41.87-72.25;P<0.01).CONCLUSION:Although a technically demanding and time-consuming procedure,LGD2 may be safe and effective,and offer some advantages over OGD2 for treatment of locally AGC.Zhen-Hong Zou Li-Ying Zhao Ting-Yu Mou Yan-Feng Hu Jiang Yu Hao Liu Hao Chen Jia-Ming Wu Sheng-Li An Guo-Xin Li 2014World Journal of Gastroenterology2014,20,44:25
8Recent progress in high temperature permanent magnetic materials显示文摘Permanent magnetic materials capable of operating at high temperature up to 500°C have wide potential applications in fields such as aeronautics,space,and electronic cars.SmCo alloys are candidates for high temperature applications,since they have large magnetocrystalline anisotropy field(6–30 T),high Curie temperature(720–920°C),and large energy product([200 kJám-3)at room temperature.However,the highest service temperature of commercial 2:17type SmCo magnets is only 300°C,and many efforts have been devoted to develop novel high temperature permanent magnets.This review focuses on the development of three kinds of SmCo based magnets:2:17 type SmCo magnets,nanocrystalline SmCo magnets,and nanocomposite SmCo magnets.The oxidation protection,including alloying and surface modification,of high temperature permanent magnets is discussed as well.Cheng-Bao Jiang Shi-Zhong An 2013Rare Metals2013,32,5:21
9Overexpression of p27^(KIP1)induced cell cycle arrest in G_1 phase and subsequent apoptosis in HCC-9204 cell line显示文摘AIM We have previously reported that inducibleover-expression of Bak may prolong cell cycle inG1 phase and lead to apoptosis in HCC-9204 cells.This study is to investigate whether p27KIP1playsan important role in this process.METHODS In order to elucidate the exactfunction of p27KIP1in this process,a zinc induciblep27KIP1stable transfectant and transient p27KIP1-GFP fusion transfectant were constructed.Theeffects of inducible,p27KIP1on cell growth,cellcycle arrest and apoptosis were examined in themock,control pMD vector,and pMD-KIP1transfected HCC-9204 cells.RESULTS This p27KIP1-GFP transfectant maytransiently express the fusion gene.The cellgrowth was reduced by 35% at 48 h of p27KIP1induction with zinc treatment as determined bytrypan blue exclusion assay.These differencesremained the same after 72 h of p27KIP1expression,p27KIP1caused cell cycle arrest after24 h of induction,with 40% increase in G1population.Prolonged p27KIP1expression in thiscell line induced apoptotic cell death reflected byTUNEL assay.Fourty-eight h and 72 h of p27KIP1expression showed a characteristic DNA ladder onagarose gel electrophoresis. CONCLUSION Bak may induce cell cycle arrest inG1 phase through upregulating expression ofp27KIP1and subsequently lead to apoptosis inHCC-9204 cells.The p27KIP1-GFP fusion proteincan be transiently expressed in HCC-9204 cells.The inducible p27KIP1-expressing cell line providesa model to assess p27KIP1function.Jiang Li Xin Ke Yang Xin Xin Yu Meng Liang Ge Wen Liang Wang Jie Zhang Yun De Hou Department of Pathology,Fourth Military Medical University,Xi’an 710033,Shaanxi Province,China State Key Laboratory for Molecular Virology and Genetic Engineering,Beijing 100052,China Department of Dermatology,Beijing Hospital,Beijing 100016,China Institute of Radiation Medicine,Beijing 100085,China 2000World Journal of Gastroenterology2000,6,4:20

13Geochronology and Petrogenesis of Triassic High-K Calc-Alkaline Granodiorites in the East Kunlun Orogen,West China:Juvenile Lower Crustal Melting during Post-Collisional Extension显示文摘This study reports zircon U-Pb and Hf isotopes and whole-rock elemental data for granodiorites from the East Kunlun orogen. The zircon U-Pb dating defines their crystallization age of 235 Ma. The rocks are characterized by high-K calc-alkaline, magnesian and metaluminous with(K_2O+Na_2O)=6.38 wt.%–7.01 wt.%, Mg#=42–50 [Mg#=100×molar Mg/(Mg+Fe OT)], A/CNK=0.92–0.98, coupled with high εHf(t) values from-0.65 to-1.80. The rocks were derived from partial melting of a juvenile mafic crustal source within normal crust thickness. The juvenile lower crust was generated by mixing lithospheric mantle-derived melt(55%–60%) and supracrustal melt(40%–45%) during the seafloor subduction. Together with available data from the East Kunlun, it is proposed that the studied Middle Triassic granodiorites were formed in post-collisional extension setting, in which melting of the juvenile lower crust in response to the basaltic magma underplating resulted in the production of high-K granodioritic melts.Fuhao Xiong Changqian Ma Hong’an Jiang Hang Zhang 2016Journal of Earth Science2016,27,3:16
14Enhancing photocatalytic performance by constructing ultrafine TiO2 nanorods/g-C3N4 nanosheets heterojunction for water treatment显示文摘Photocatalysis is considered to be a clean, green and efficient method to purify water. In this report, we first developed a highly efficient ultrafine TiO_2 nanorods/g-C3 N4 nanosheets(TiO_2 NR/CN NS) composites via a simple hydrothermal method. Tiny TiO_2 nanorods(diameter:~1.5 nm and length:~8.3 nm) were first loaded in situ on the CN NS by adding graphitic carbon nitride(g-C3 N4) to the reaction solution.The TiO_2 NR/CN NS composites present high charge separation efficiency and broader light absorbance than P25 TiO_2. Furthermore, we illustrate that the Ti0_2 NR/CN NS catalyst possesses high performance for the photocatalytic degradation of the common and stubborn pollutants in water, such as the rhodamine B(RhB) dye and phenol. Under visible light(λ> 420 nm) irradiation, the apparent rate of the TiO_2 NR/CN NR is 172 and 41 times higher than that of the P25 TiO_2 and TiO_2 NR, respectively.Additionally, we speculated that the heterojunction formed between TiO_2 NR and CN NS, which is the basis for the experiments we have designed and the corresponding results. We demonstrated that reactive oxidative species such as superoxide anion radical and holes play critical roles in the degradation,and the hydroxyl radical contributes nothing to the degradation.Shiliang Luan Dan Qu Li An Wenshuai Jiang xiang Gao Shixin Hua Xiang Miao Yuanjing Wen Zaicheng Sun 2018Science Bulletin2018,63,11:16

16Modeling the climate effects of different subregional uplifts within the Himalaya-Tibetan Plateau on Asian summer monsoon evolution显示文摘Considering the different uplifting time of different subregions of the Himalaya-Tibetan Plateau(TP),a series of numerical simulations have been conducted with the Community Atmosphere Model(CAM4) developed at the National Center for Atmospheric Research to explore the effects of the phased tectonic uplift of the Himalaya-TP on the evolution of Asian summer monsoons.The results show that the uplifts of the Himalaya and northern TP significantly affect the evolutions of South Asian summer monsoon and northern East Asian summer monsoon respectively.That is,the tectonic uplift of the Himalaya intensifies the South Asian summer monsoon circulation and increases the precipitation in South Asia,whereas the uplift of the northern TP intensifies the northern East Asian summer monsoon circulation and increases the precipitation in northern East Asia.Compared with previous simulations,current comparative analyses of modeling results for different subregional uplifts within the Himalaya-TP help deepen our understanding of the evolutionary history of Asian monsoons.ZHANG Ran 1,JIANG DaBang 1,2,3,LIU XiaoDong 4 & TIAN ZhiPing 2,5 1 Climate Change Research Center,Chinese Academy of Sciences,Beijing 100029,China 2 Nansen-Zhu International Research Centre,Institute of Atmospheric Physics,Chinese Academy of Sciences,Beijing 100029,China 3 Key Laboratory of Regional Climate-Environment Research for Temperate East Asia,Chinese Academy of Sciences,Beijing 100029,China 4 State Key Laboratory of Loess and Quaternary Geology,Institute of Earth Environment,Chinese Academy of Sciences,Xi’an 710075,China 5 Graduate University of Chinese Academy of Sciences,Beijing 100049,China 2012Chinese Science Bulletin2012,57,35:14

18High speed robust image registration and localization using optimized algorithm and its performances evaluation显示文摘Local invariant algorithm applied in downward-looking image registration,usually computes the camera's pose relative to visual landmarks.Generally,there are three requirements in the process of image registration when using these approaches.First,the algorithm is apt to be influenced by illumination.Second,algorithm should have less computational complexity.Third,the depth information of images needs to be estimated without other sensors.This paper investigates a famous local invariant feature named speeded up robust feature(SURF),and proposes a highspeed and robust image registration and localization algorithm based on it.With supports from feature tracking and pose estimation methods,the proposed algorithm can compute camera poses under different conditions of scale,viewpoint and rotation so as to precisely localize object's position.At last,the study makes registration experiment by scale invariant feature transform(SIFT),SURF and the proposed algorithm,and designs a method to evaluate their performances.Furthermore,this study makes object retrieval test on remote sensing video.For there is big deformation on remote sensing frames,the registration algorithm absorbs the Kanade-Lucas-Tomasi(KLT) 3-D coplanar calibration feature tracker methods,which can localize interesting targets precisely and efficiently.The experimental results prove that the proposed method has a higher localization speed and lower localization error rate than traditional visual simultaneous localization and mapping(vSLAM) in a period of time.Meng An Zhiguo Jiang Danpei Zhao 2010Journal of Systems Engineering and Electronics2010,21,3:13
19A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice.Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan 2019Cell Research2019,29,10:13
20COVID-19: Challenges to GIS with Big Data显示文摘The outbreak of the 2019 novel coronavirus disease(COVID-19)has caused more than 100,000 people infected and thousands of deaths.Currently,the number of infections and deaths is still increasing rapidly.COVID-19 seriously threatens human health,production,life,social functioning and international relations.In the fight against COVID-19,Geographic Information Systems(GIS)and big data technologies have played an important role in many aspects,including the rapid aggregation of multi-source big data,rapid visualization of epidemic information,spatial tracking of confirmed cases,prediction of regional transmission,spatial segmentation of the epidemic risk and prevention level,balancing and management of the supply and demand of material resources,and socialemotional guidance and panic elimination,which provided solid spatial information support for decision-making,measures formulation,and effectiveness assessment of COVID-19 prevention and control.GIS has developed and matured relatively quickly and has a complete technological route for data preparation,platform construction,model construction,and map production.However,for the struggle against the widespread epidemic,the main challenge is finding strategies to adjust traditional technical methods and improve speed and accuracy of information provision for social management.At the data level,in the era of big data,data no longer come mainly from the government but are gathered from more diverse enterprises.As a result,the use of GIS faces difficulties in data acquisition and the integration of heterogeneous data,which requires governments,businesses,and academic institutions to jointly promote the formulation of relevant policies.At the technical level,spatial analysis methods for big data are in the ascendancy.Currently and for a long time in the future,the development of GIS should be strengthened to form a data-driven system for rapid knowledge acquisition,which signifies ts that GIS should be used to reinforce the social operation parameterization of models and methods,especially when providing support for social management.Chenghu Zhou Fenzhen Su Tao Pei An Zhang Yunyan Du Bin Luo Zhidong Cao Juanle Wang Wen Yuan Yunqiang Zhu Ci Song Jie Chen Jun Xu Fujia Li Ting Ma Lili Jiang Fengqin Yan Jiawei Yi Yunfeng Hu Yilan Liao Han Xiao 2020Geography and Sustainability2020,1,1:13
