3Genome-wide analysis of heat shock transcription factor families in rice and Arabidopsis显示文摘The heat shock transcription factors (HSFs) are the major heat shock factors regulating the heat stress response. They participate in regulating the expression of heat shock proteins (HSPs), which are critical in the protection against stress damage and many other important biological processes. Study of the HSF gene family is important for understanding the mechanism by which plants respond to stress. The completed genome sequences of rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana) constitute a valuable resource for comparative genomic analysis, as they are representatives of the two major evolutionary lineages within the angiosperms: the monocotyledons and the dicotyledons. The identification of phylogenetic relationships among HSF proteins in these species is a fundamental step to unravel the functionality of new and yet uncharacterized genes belonging to this family.In this study, the full complement of HSF genes in rice and Arabidopsis has probably been identified through the genome-wide scan. Phylogenetic analyses resulted in the identification of three major clusters of orthologous genes that contain members belonging to both species, which must have been represented in their common ancestor before the taxonomic splitting of the angiosperms. Further analysis of the phylogenetic tree reveals a possible dicot specific gene group. We also identified nine pairs of paralogs, as evidence for studies on the evolution history of rice HSF family and rice genome evolution. Expression data analysis indicates that HSF proteins are widely expressed in plants. These results provide a solid base for future functional genomic studies of the HSF gene family in rice and Arabidopsis.Jingkang Guo Jian Wu Qian Ji Chao Wang Lei Luo Yi Yuan Yonghua Wang Jian Wang 2008Journal of Genetics and Genomics2008,35,2:52
4Effects of AT1 receptor antagonist,Iosartan,on rat hepatic fibrosis induced by CCl_4显示文摘AIM To investigate effect of losartan,an AT1receptor antagonist,on hepatic fibrosis induced byCCl;and to determine whether or not AT1receptors are expressed on hepatic stellate cells,METHODS AND RESULTS Fifty male Sprague-Dawley rats,weighing(180±20)g,wererandomized into five groups(control group,modelgroup,and three losartan treated groups),inwhich all rats were given the subcutaneousinjection of 40% CCl4(every 3 days for 6 weeks)except for rats of control group.Rats of losartan-treated groups were treated with losartan(20 mg/kg,10 mg/kg,5 mg/kg,daily gavage),After 6weeks liver tissue and serum samples of all ratswere examined.Serum hyaluronic acid(HA),procollagen typeⅢ(PCⅢ)were detected byradioimmunoassays,van Giesion collagen stainingwas used to evaluate the extracellular matrix of ratswith liver fibrosis.The expression of AT1receptors,transforming growth factor-beta(TGF-β),and alpha-smooth muscle actin(a-SMA)inliver tissue were determined byimmunohistochemical techniques.Compared withmodel group,serum ALT and AST of losartan-treated groups were significantly reduced(t=4.20,P<0.01 and t=4.57,P<0.01).Serum HAand PCⅢalso had significant differences(t=3.53,P<0.01 and t=2.20,P<0.05).Thedegree of fibrosis was improved by losartan and correlated with the expressions of AT1 receptors,TGF-β,and α-SMA in liver tissue.CONCLUSION AT1 receptor antagonist,losartan,could limit the progression of the hepatic fibrosisinduced by CCl4.The mechanism may be related tothe decrease in the expression of AT1 receptorsand TGF-β,ameliorating the injury of hepatocytes;activation of local renin-angiotensin system mightrelate to hepatic fibrosis;and during progressionof fibrosis,activated hepatic stellate cells mightexpress AT1 receptors.Hong Shan Wei Ding Guo Li Han Ming Lu Yu Tao Zhan Zhi Rong Wang Xin Huang Jing Zhang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China 2000World Journal of Gastroenterology2000,6,4:42

6Linking atmospheric pollution to cryospheric change in the Third Pole region: current progress and future prospects显示文摘The Tibetan Plateau and its surroundings are known as the Third Pole(TP). This region is noted for its high rates of glacier melt and the associated hydrological shifts that affect water supplies in Asia. Atmospheric pollutants contribute to climatic and cryospheric changes through their effects on solar radiation and the albedos of snow and ice surfaces; moreover, the behavior and fates within the cryosphere and environmental impacts of environmental pollutants are topics of increasing concern. In this review, we introduce a coordinated monitoring and research framework and network to link atmospheric pollution and cryospheric changes(APCC) within the TP region. We then provide an up-to-date summary of progress and achievements related to the APCC research framework, including aspects of atmospheric pollution’s composition and concentration, spatial and temporal variations, trans-boundary transport pathways and mechanisms, and effects on the warming of atmosphere and changing in Indian monsoon, as well as melting of glacier and snow cover. We highlight that exogenous air pollutants can enter into the TP’s environments and cause great impacts on regional climatic and environmental changes. At last, we propose future research priorities and map out an extended program at the global scale. The ongoing monitoring activities and research facilitate comprehensive studies of atmosphere–cryosphere interactions, represent one of China’s key research expeditions to the TP and the polar regions and contribute to the global perspective of earth system science.Shichang Kang Qianggong Zhang Yun Qian Zhenming Ji Chaoliu Li Zhiyuan Cong Yulan Zhang Junming Guo Wentao Du Jie Huang Qinglong You Arnico K.Panday Maheswar Rupakheti Deliang Chen Orjan Gustafsson Mark H.Thiemens Dahe Qin 2019National Science Review2019,6,4:35
7A Positioning System based on Communication Satellites and the Chinese Area Positioning System(CAPS)显示文摘The Chinese Area Positioning System(CAPS) is a positioning system based on satellite communication that is fundamentally different from the 3'G'(GPS,GLONASS and GALILEO) systems.The latter use special-purpose navigation satellites to broadcast navi-gation information generated on-board to users,while the CAPS transfers ground-generated navigation information to users via the communication satellite.In order to achieve accurate Positioning,Velocity and Time(PVT),the CAPS employs the following strategies to over-come the three main obstacles caused by using the communication satellite:(a) by real-time following-up frequency stabilization to achieve stable frequency;(b) by using a single carrier in the transponder with 36 MHz band-width to gain sufficient power;(c) by incorporating Decommissioned Geostationary Orbit communication satellite(DGEO),barometric pressure and Inclined Geostationary Orbit communication satellite(IGSO) to achieve the 3-D posi-tioning.Furthermore,the abundant transponders available on DGEO can be used to realize the large capacity of communication as well as the integrated navigation and communication.With the communication functions incorporated,five new functions appear in the CAPS:(1) combination of navigation and communication;(2) combination of navigation and high accu-racy orbit measurement;(3) combination of navigation message and wide/local area differen-tial processing;(4) combination of the switching of satellites,frequencies and codes;and(5) combination of the navigation message and the barometric altimetry.The CAPS is thereby labelled a PVT5C system of high accuracy.In order to validate the working principle and the performance of the CAPS,a trial system was established in the course of two years at a cost of about 20 million dollars.The trial constellation consists of two GEO satellites located at E87.5° and E110.5°,two DGEOs located at E130° and E142°,as well as barometric altimetry as a virtual satellite.Static and dynamic performance tests were completed for the Eastern,the Western,the Northern,the Southern and the Middle regions of China.The evaluation results are as follows:(1) land static test,plane accuracy range:C/A code,15~25m;P code,5~10 meters;altitude accuracy range,1~3 m;(2) land dynamic test,plane accuracy range,C/A code,15~25m;P code,8~10m;(3) velocity accuracy,C/A code,0.13~0.3ms-1,P code,0.15~0.17ms-1;(4) timing accuracy,C/A code,160ns,P code,13 ns;(5) timing compared accuracy of Two Way Satellite Time and Frequency Transfer(TWSTFT),average accuracy,0.068ns;(6) random error of the satellite ranging,10.7 mm;(7) orbit determination accuracy,better than 2 m.The above stated random error is 1σ error.At present,this system is used as a preliminary operational system and a complete system with 3 GEO,3 DGEO and 3 IGSO is being established.Guo-Xiang Ai Hu-Li Shi Hai-Tao Wu Yi-Hua Yan Yu-Jing Bian Yong-Hui Hu Zhi-Gang Li Ji Guo Xian-De Cai 2008Chinese Journal of Astronomy and Astrophysics2008,8,6:33

10Hypoxic preconditioning stimulates angiogenesis in ischemic penumbra after acute cerebral infarction显示文摘Previous studies have demonstrated the protective effect of hypoxic preconditioning on acute cerebral infarction,but the mechanisms underlying this protection remain unclear.To investigate the protective mechanisms of hypoxic preconditioning in relation to its effects on angiogenesis,we induced a photochemical model of cerebral infarction in an inbred line of mice(BALB/c).Mice were then exposed to hypoxic preconditioning 30 minutes prior to model establishment.Results showed significantly increased vascular endothelial growth factor and CD31 expression in the ischemic penumbra at 24 and 72 hours post infarction,mainly in neurons and vascular endothelial cells.Hypoxic preconditioning increased vascular endothelial growth factor and CD31 expression in the ischemic penumbra and the expression of vascular endothelial growth factor was positively related to that of CD31.Moreover,hypoxic preconditioning reduced the infarct volume and improved neurological function in mice.These findings indicate that the protective role of hypoxic preconditioning in acute cerebral infarction may possibly be due to an increase in expression of vascular endothelial growth factor and CD31 in the ischemic penumbra,which promoted angiogenesis.Sijie Li Yanbo Zhang Guo Shao Mingfeng Yang Jingzhong Niu Guowei Lv Xunming Ji 2013Neural Regeneration Research2013,8,31:31

14The mechanism and risk factors for immune checkpoint inhibitor pneumonitis in non-small cell lung cancer patients显示文摘Immune checkpoint inhibitors(ICIs)are new and promising therapeutic agents for non-small cell lung cancer(NSCLC).However,along with demonstrating remarkable efficacy,ICIs can also trigger immune-related adverse events.Checkpoint inhibitor pneumonitis(CIP)has been reported to have a morbidity rate of 3%to 5%and a mortality rate of 10%to 17%.Moreover,the incidence of CIP in NSCLC is higher than that in other tumor types,reaching 7%to 13%.With the increased use of ICIs in NSCLC,CIP has drawn extensive attention from oncologists and cancer researchers.Identifying high risk factors for CIP and the potential mechanism of CIP are key points in preventing and monitoring serious adverse events.In this review,the results of our analysis and summary of previous studies suggested that the risk factors for CIP may include previous lung disease,prior thoracic irradiation,and combinations with other drugs.Our review also explored potential mechanisms closely related toCIP,including increasedT cell activity against associated antigens in tumor and normal tissues,preexisting autoantibodies,and inflammatory cytokines.Xiaoyang Zhai Jian Zhang Yaru Tian Ji Li Wang Jing Hongbo Guo Hui Zhu 2020Cancer Biology & Medicine2020,17,3:25

18Motion trajectory prediction based on a CNN-LSTM sequential model显示文摘Accurate monitoring the surrounding environment is an important research direction in the field of unmanned systems such as bio-robotics,and has attracted much research attention in recent years.The trajectories of surrounding vehicles should be predicted accurately in space and time to realize active defense and running safety of an unmanned system.However,there is uncertainty and uncontrollability in the process of trajectory prediction of surrounding obstacles.In this study,we propose a trajectory prediction method based on a sequential model,that fuses two neural networks of a convolutional neural network(CNN)and a long short-term memory network(LSTM).First,a box plot is used to detect and eliminate abnormal values of vehicle trajectories,and valid trajectory data are obtained.Second,the trajectories of surrounding vehicles are predicted by merging the characteristics of CNN space expansion and LSTM time expansion;the hyper-parameters of the model are optimized according to a grid search algorithm,which satisfies the double-precision prediction requirement in space and time.Finally,data from next generation simulation(NGSIM)and Creteil roundabout in France are taken as test cases;the correctness and rationality of the method are verified by prediction error indicators.Experimental results demonstrate that the proposed CNNLSTM method is more accurate and features a shorter time cost,which meets the prediction requirements and provides an effective method for the safe operation of unmanned systems.Guo XIE Anqi SHANGGUAN Rong FEI Wenjiang JI Weigang MA Xinhong HEI 2020Science China(Information Sciences)2020,63,11:24
