1Arctic Sea Ice and Eurasian Climate:A Review显示文摘The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades,including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the Arctic warming and reduction of Arctic sea ice, Europe, East Asia and North America have experienced anomalously cold conditions, with record snowfall during recent years. In this paper, we review current understanding of the sea-ice impacts on the Eurasian climate.Paleo, observational and modelling studies are covered to summarize several major themes, including: the variability of Arctic sea ice and its controls; the likely causes and apparent impacts of the Arctic sea-ice decline during the satellite era,as well as past and projected future impacts and trends; the links and feedback mechanisms between the Arctic sea ice and the Arctic Oscillation/North Atlantic Oscillation, the recent Eurasian cooling, winter atmospheric circulation, summer precipitation in East Asia, spring snowfall over Eurasia, East Asian winter monsoon, and midlatitude extreme weather; and the remote climate response(e.g., atmospheric circulation, air temperature) to changes in Arctic sea ice. We conclude with a brief summary and suggestions for future research.GAO Yongqi SUN Jianqi LI Fei HE Shengping Stein SANDVEN YAN Qing ZHANG Zhongshi Katja LOHMANN Noel KEENLYSIDE Tore FUREVIK SUO Lingling 2015Advances in Atmospheric Sciences2015,32,1:21
2Design,modeling,and control of morphing aircraft:A review显示文摘A morphing aircraft can adapt its configuration to suit different types of tasks,which is also an important requirement of Unmanned Aerial Vehicles(UAV).The successful development of an unmanned morphing aircraft involves three steps that determine its ability and intelligent:configuration design,dynamic modeling and flight control.This study conducts a comprehensive survey of morphing aircraft.First,the methods to design the configuration of a morphing aircraft are presented and analyzed.Then,the nonlinear dynamic characteristics and aerodynamic interference caused by a morphing wing are described.Subsequently,the dynamic modeling and flight control methods for solving the flight control problems are summarized with respect to these features.Finally,the general as well as special challenges ahead of the development of intelligent morphing aircraft are discussed.The findings can provide a theoretical and technical reference for designing future morphing aircraft or morphing-wing UAVs.Lingling CHU Qi LI Feng GU Xintian DU Yuqing HE Yangchen DENG 2022Chinese Journal of Aeronautics2022,35,5:16

5Toxicological effects involved in risk assessment of rare earth lanthanum on roots of Vicia faba L.seedlings显示文摘Combined chemical analyses and biological measurements were utilized to investigate potential toxicological effects and possible mechanisms involved in risk assessment of rare earth elements (REEs) on Vicia faba L.seedlings,which were hydroponically cultivated and exposed to various concentrations of lanthanum (La) for 15 days.The results showed that La contents in both the solution and roots increased with the increase of extraneous La,contributing to hormetic dose responses of superoxide dismutase (SOD),catalase (CAT),guaiacol peroxidase (GPX),ascorbate peroxidase (APX) and endoprotease (EP) isozymes activities,and HSP 70 production enhanced at low doses but suppressed at higher doses of La.These physiological responses constituted antioxidant and detoxification systems against La-induced oxidative stress.The elevated La levels also contributed to oxidatively modified proteins,which were most responsible for subsequent cell death and growth retardation of the roots.By combination of hormetic and traditional threshold dose levels,the threshold dose range was deduced to be 108-195 μg La/g dry weight in the roots,corresponding to 0.90-3.12 mg/L of soluble La in the culture solution.It suggests that persistent applications of REEs may lead to potential ecological risk in the environment.Chengrun Wang Mei He Wen Shi Jessie Wong Tao Cheng Xiaorong Wang Lingling Hu Fenfen Chen 2011Journal of Environmental Sciences2011,23,10:9
6WIP1 Phosphatase Plays a Critical Neuroprotective Role in Brain Injury Induced by High-Altitude Hypoxic Inflammation显示文摘The hypobaric hypoxic environment in highaltitude areas often aggravates the severity of inflammation and induces brain injury as a consequence. However, the critical genes regulating this process remain largely unknown. The phosphatase wild-type p53-induced phosphatase 1(WIP1) plays important roles in various physiological and pathological processes, including the regulation of inflammation in normoxia, but its functions in hypoxic inflammation-induced brain injury remain unclear.Here, we established a mouse model of this type of injury and found that WIP1 deficiency augmented the release of inflammatory cytokines in the peripheral circulation and brain tissue, increased the numbers of activated microglia/macrophages in the brain, aggravated cerebral histological lesions, and exacerbated the impairment of motor and cognitive abilities. Collectively, these results provide the first in vivo evidence that WIP1 is a critical neuroprotector against hypoxic inflammation-induced brain injury.Dahu Li Lijun Zhang Xin Huang Lili Liu Yunling He Lun Xu Yiyao Zhang Tong Zhao Liying Wu Yongqi Zhao Kuiwu Wu Yan Wu Ming Fan Lingling Zhu 2017Neuroscience Bulletin2017,33,3:9
7Synoptic-scale variation of δ^(18)O in summer monsoon rainfall at Lijiang, China显示文摘Based on the daily δ^(18)O data in June―September 2003 at Lijiang and the daily mean NCEP/ NCAR reanalysis data, synoptic-scale variation of δ^(18)O in summer monsoon rainfall was investigated. The 'precipitation amount effect' is obvious for the daily δ^(18)O variation, whereas the 'temperature effect' is insignificant. Alternate occurrences of active phase and break phase of the southwest monsoon probably influence the synoptic-scale δ^(18)O variation prominently. Moreover, the isotopic composition in precipitation during the late monsoon months is presumably influenced significantly by recycling of monsoon precipitation. Both the above factors disturb the 'amount effect' of isotopic variation in the monsoon region. This study also indicates that the synoptic-scale rainfall δ^(18)O variation at Lijiang in summer is domi-nated by the Indian monsoon depression (low pressure) system at large scale. These results are important for further studying the 'amount effect' and reconstructing paleoclimate in the monsoon region.PANG Hongxi HE Yuanqing LU Aigang ZHAO Jingdong NING Baoying YUAN Lingling SONG Bo 2006Chinese Science Bulletin2006,51,23:9
8Mechanism of acupuncture regulating visceral sensation and mobility显示文摘Chinese ancient medical scientists have long focused on the internal and external contacts between acupoints on the surface of the body and the viscera.The Miraculous Pivot(it is one of the earliest medical classics in China)stated,“Twelve regular channels belong to the zang-fu organs internally,and connect to the extremities and joints externally.”Traditional Chinese medicine considers acupoints as defined areas where the Qi of viscera and meridians are transfused.These include the reaction points of visceral diseases on the body surface as well as the acupuncture trigger points that promote the flow of Qi and blood,and regulate visceral function.Chinese ancient medical scientists classified the specificity of the main acupoints in the body based on the meridian doctrine,which has been instructing clinical application for about 2000 years.Laws on the domino effect of acupoints have mainly focused on conclusions to clinical experiences.Indications of some acupoints exceed the practical paradigm since the excessive extension occurred during theory derivation.The current research direction on acupuncture focuses on three aspects:the effectiveness of acupuncture and moxibustion;the relevances and associations between meridians and viscera;and the physical and chemical properties and relevant physical basis of acupoints.The relevance between meridians and viscera is the central theory in the meridian doctrine,and acupoints are regarded as an important link in the relationship between meridians and viscera.Specific relationships between acupoints and target organs exist.Stimulating different acupoints on the body surface can help deal with different diseases,especially visceral diseases.In addition,acupoints have a dual function of reflecting and treating visceral diseases.There is no systemic research available on acupoint specificity,despite current knowledge and clinical experiences,which results in a weak foundation for acupuncture theory.This study focuses on the relevance and associations between meridians and viscera.A summary of the mechanisms of acupuncture regulating visceral sensation and mobility and the specific relationships between acupoints and their target organs are presented in this review.Peijing Rong Bing Zhu Yuqing Li Xinyan Gao Hui Ben Yanhua Li Liang Li Wei He Rupeng Liu Lingling Yu 2011Frontiers of Medicine2011,5,2:8
9Sirtuin 5:a review of structure,known inhibitors and clues for developing new inhibitors显示文摘Sirtuins(SIRTs) are nicotinamide adenine dinucleotide(NAD^+)-dependent protein deacetylases,which regulate important biological processes ranging from apoptosis,age-associated pathophysiologies,adipocyte and muscle differentiation,and energy expenditure to gluconeogenesis.Very recently,sirtuin 5(SIRT5) has received considerable attention due to that it was found to have weak deacetylase activity but strong desuccinylase,demalonylase and deglutarylase activities,and it was also found to be associated with several human diseases such as cancer,Alzheimer's disease,and Parkinson's disease.In this review,we for the first time summarized the structure characteristics,known peptide and small-molecule inhibitors of SIRT5,extracted some clues from current available information and introduced some feasible,practical in silico methods,which might be useful in further efforts to develop new SIRT5 inhibitors.Lingling Yang Xiaobo Ma Yanying He Chen Yuan Quanlong Chen Guobo Li Xianggui Chen 2017Science China(Life Sciences)2017,60,3:7
10Effect of Landform on Seasonal Temperature Structures across China in the Past 52 Years显示文摘The data of 160 national meteorological observatory stations including the long-term monthly temperature data in China were analyzed to study the seasonal variation of the spatial temperature structures across China in the past half century. It is found that temperature structures differ between seasons: a latitude temperature pattern in winter and a landform temperature pattern in summer, which indicate that the effect of landform on temperature structure is much stronger in summer than that in winter and the effect of latitudinal temperature is much stronger in winter than that in summer. The mechanisms of the seasonal difference in temperature structures are also discussed in this paper.LU Aigang PANG Deqian GE Jianping HE Yuanqing PANG Hongxi YUAN Lingling 2006Journal of Mountain Science2006,3,2:7

12The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5

15CFD-DEM simulation of fluid-solid flow of a tapered column separation bed显示文摘Research on recycling waste Printed Circuit Boards(PCB) is at the forefront of preventing environmental pollution and finding ways to recycle resources.The Tapered Column Separation Bed(TCSB) is invented aiming at disposing the problem that fine particles of waste printed circuit boards cannot be separated efficiently so as to obtain further insight about the underlying mechanisms and demonstrate the separation feasibility in the tapered column separation bed.In this work,a Computational Fluid Dynamics(CFD) coupled with Discrete Element Method(DEM) model for two-phase flow has been extended to simulate the fluid-solid flow in the tapered column separation bed.Its validity is demonstrated by its successful capturing the key features of particles' flow pattern,velocity,the pressure distribution,the axial position with time and axial force for particles with different densities.Simulation results show that the plastic particles and resin particles become overflow,while copper particles,iron particles and aluminum particles successively become underflow,with a discharge water flow rate of 1 m^3/h,an obliquity of 30°.The simulated results agree reasonably well with the experimental observation.Using this equipment to separate waste PCBs is feasible,theoretically.Duan Chenlong Sheng Cheng Wu Lingling Zhao Yuemin He Jinfeng 2015International Journal of Mining Science and Technology2015,25,5:4

17Impact of Global Warming on Water Resource in Arid Area of Northwest China显示文摘As the unprecedented global warming is under way, the glacier retreat is getting more and more serious. In the inland arid area of Northwest China, due to very scarce precipitation, where there is water, there are oases. And the glacier melt water amounts to 22 % of the total direct supply of the inland river water and is of crucial importance to the survival and development of the oases. In this paper, using both the observed data and the previous research achievements of the glaciers in the inland valley of Northwest China where the oasis depending on the glacier is the only location suitable for human living, the authors describe the glacier retreat trend over the past half century, focusing on discussing the possible impact of the glacier retreat on the melt water runoff that is almost the only water resource efficient to nourish the oases. The authors find that even with increasing amount of water from the glacier with global warming, the water shortage is getting more and more serious and the environment is under a degrading way due to the accelerating economical development. The water shortage is bound to be more serious if the glacier retreat keeps on, especially after the glacier melt water is over its top for the degradedglacier scale. So suggestions are stressed in the end that a new water-saving pattern should be adopted in the area for a sustainable development due to the warming-up induced continuous glacier retreat.LU Aigang DING Yongjian PANG Hongxi YUAN Lingling HE Yuanqing 2005Journal of Mountain Science2005,2,4:3
18Effect of acupuncture treatment on smoking cessation in smokers from Hong Kong显示文摘OBJECTIVE: To analyze the characteristics of smokers treated with acupuncture for smoking cessation in Hong Kong.METHODS: A total of 2051 subjects were recruited in a clinical pilot research project 'acupuncture for smoking cessation', which was conducted jointly by Institute of Acupuncture and Moxibustion, China Academy of Chinese Medical Sciences and Hong Kong Pok Oi Hospital from January of 2011 to December of 2013. The characteristics of study subjects, including baseline information, smoking background, intention to quit and influencing factors were analyzed.RESULTS: The majority of subjects treated with acupuncture for smoking cessation in Hong Kong was male(66.7%), but the proportion of female smokers in this study(33.3%) was higher than that of female smokers in Hong Kong population(13.8%, P <0.05). Subjects were at the mean age of 43.83 years old, of which the percentage of females aged 31-40 years was the highest(38.8%, P < 0.05). The mean duration of smoking was 25.49 years. The number of cigarettes smoked per day was 17.57 cigarettes.Fagerstrom Test for Nicotine Dependence(FTND)was 5.29 points. Most of the subjects had attempted quitting smoking(81.42%). The confidence index(7.44 points) and the readiness to quit smoking(8.13 points) were high. Subjects quitting smoking were mostly due to health cause(81.91%). The majority of subjects were at the level of middle school(61.63%). The higher the educational level was, the lower the tobacco dependence was and the higher the confidence in successfully quitting smoking was. 50.27% of subjects chose acupuncture for smoking cessation mainly through friends, television and network publicity. Subjects who had received acupuncture had the highest confidence index, while those who wanted to try a new method had the lower confidence index.CONCLUSION: Acupuncture for smoking cessation was more popular in female smokers, especially those aged 31-40 years. The effectiveness of acupuncture-smoking cessation was most significant in the smokers over 60.Wang Yingying Liu Zhao Zhang Ou Chen Min Huang Lingling Wu Yuan Zhang Fanfan Wu Guanyi He Xiuqing Yang Jinsheng 2016Journal of Traditional Chinese Medicine2016,36,5:3
19Effects of surface modifications on the physicochemical properties of iron oxide nanoparticles and their performance as anticancer drug carriers显示文摘The feature of the surface coating can affect important properties of iron oxide nanoparticles(IONPs), it is therefore critical for further understanding how these materials react to physiological conditions, which is still needed to fully exploit the potential of IONPs for their theranostiThe feature of the surface coating can affect important properties of iron oxide nanoparticles(IONPs), it is therefore critical for further understanding how these materials react to physiological conditions, which is still needed to fully exploit the potential of IONPs for their theranostic applications. In this work, we prepared IONPs which surface were modified with citric acid(CA), chitosan(CS) and folic acid conjugated chitosan(FA-g-CS). respectively. Their physicochemical properties were investigated using FT-IR, TEM,powder XRD, VSM, TGA, DLS and zeta potential. We found that CA-IONP dispersion was composed of monocrystalline particles while CS-IONP and FA-g-CS-IONP were composed of polycrystalline aggregates. All IONPs retained the crystalline structure of magnetite and exhibited the superparamagnetic behavior. Their saturation magnetization decreased with the increase in the amount of their organic coatings. Their drug loading capacities, drug release patterns and in vitro anticancer efficiencies were studied by using doxorubicin(DOX) as a model drug. DOX@CS-IONP and DOX@FA-g-CSIONP exhibited lower drug loading while showing higher water dispersity when compared with DOX@CA-IONP. All IONPs were surface charged and they tended to agglomerate in medium with high pH value and ionic strength. In the presence of chitosan or FA-g-CS coatings, their DOX release rate was slowed down compared with that of DOX@CA-IONP. Unloaded IONPs exhibited nearly no cytotoxicity on both cancer cells and normal cells in the presence of chitosan and FA-g-CS when compared with CA-IONP which presented high cytotoxicity. However, DOX@FA-g-CS-IONP showed significantly cytotoxicity on folate receptors(FRs) positive breast cancer cells while exhibiting nearly no cytotoxicity on FRs negative normal cells. Results presented in this study were valuable to the design and fabrication of IONPs-based system for better theranostic applications.c applications.
