| 1 | Sleep Deprivation Selectively Down-Regulates Astrocytic 5-HT2B Receptors and Triggers Depressive-Like Behaviors via Stimulating P2X7 Receptors in Mice显示文摘Chronic loss of sleep damages health and disturbs the quality of life.Long-lasting sleep deprivation(SD)as well as sleep abnormalities are substantial risk factors for major depressive disorder,although the underlying mechanisms are not clear.Here,we showed that chronic SD in mice promotes a gradual elevation of extracellular ATP,which activates astroglial P2X7 receptors(P2X7Rs).Activated P2X7Rs,in turn,selectively down-regulated the expression of 5-HT2B receptors(5-HT2BRs)in astrocytes.Stimulation of P2X7Rs induced by SD selectively suppressed the phosphorylation of AKT and FoxO3 a in astrocytes,but not in neurons.The overexpression of FoxO3a in astrocytes inhibited the expression of 5-HT2BRs.Down-regulation of 5-HT2BsRs instigated by SD suppressed the activation of STAT3 and relieved the inhibition of Ca2+-dependent phospholipase A2.This latter cascade promoted the release of arachidonic acid and prostaglandin E2.The depression-like behaviors induced by SD were alleviated in P2X7R-KO mice.Our study reveals the mechanism underlying chronic SD-induced depression-like behaviors and suggests 5-HT2BRs as a key target for exploring therapeutic strategies aimed at the depression evoked by sleep disorders. | Maosheng Xia Zexiong Li Shuai Li Shanshan Liang Xiaowei Li Beina Chen Manman Zhang Chengyi Dong Alexei Verkhratsky Dawei Guan Baoman Li | 2020 | Neuroscience Bulletin2020，36，11： | 10 |
| 2 | Advanced Functional Fiber and Smart Textile显示文摘The research and applications of fiber materials are directly related to the daily life of social populace and the development of relevant revolutionary manufacturing industry.However,the conventional fibers and fiber products can no longer meet the requirements of automation and intellectualization in modern society,as well as people’s consumption needs in pursuit of smart,avant-grade,fashion and distinctiveness.The advanced fiber-shaped electronics with most desired designability and integration features have been explored and developed intensively during the last few years.The advanced fiber-based products such as wearable electronics and smart clothing can be employed as the second skin to enhance information exchange between humans and the external environment.In this review,the significant progress on flexible fiber-shaped multifunctional devices,including fiber-based energy harvesting devices,energy storage devices,chromatic devices,and actuators are discussed.Particularly,the fabrication procedures and application characteristics of multifunctional fiber devices such as fiber-shaped solar cells,lithium-ion batteries,actuators and electrochromic fibers are introduced in detail.Finally,we provide our perspectives on the challenges and future development of functional fiber-shaped devices. | Qiuwei Shi Jianqi Sun Chengyi Hou Yaogang Li Qinghong Zhang Hongzhi Wang | 2019 | Advanced Fiber Materials2019，1，1： | 7 |
| 3 | Effect of groundwater depth on riparian plant diversity along riverside-desert gradients in the Tarim River显示文摘Aims Riparian plant diversity is sensitive to changes in groundwater in arid regions.However,little is known about how plant diversity responds to changes in environment along riverside-desert gradi-ents in riparian ecosystem.Our objectives were to(i)identify ri-parian plant diversity along riverside-desert gradients in Tarim desert riparian forests,(ii)analyze the impact of environment variables on plant diversity,(iii)determine the optimum groundwater depth for different plant life-forms.Methods Six transects 90 quadrats(with each size 100 m×100 m)distributed vertically to river bed along riverside-desert gradients~30 km in length were surveyed.At each quadrat,the morphological features of riparian plant communities were measured,and the groundwater depth,soil water,soil salinity,soil nutrient were also monitored at same sites.Important Finding Three distinct vegetation communities were identified based on cover and richness in the tree,shrub and herb layers:the riparian zone,the transitional zone and the desert margin zone.Twelve spe-cies were indicators of the three vegetation communities.Riparian plant diversity was influenced by groundwater depth,distance from river,soil moisture content,soil salinity and soil nutrient by redundancy analysis.In response to groundwater depth,the op-timal groundwater depths for species diversity,evenness and shrub cover were 2.8,2.7 and 3.7 m,respectively.Therefore,maintaining high plant diversity requires managers to ensure stable groundwater depth for different plant life-forms rather than for some of them. | Yong Zeng Chengyi Zhao Jun Li Yan Li Guanghui Lv Tong Liu | 2019 | Journal of Plant Ecology2019，12，3： | 7 |
| 4 | Isolation and identification of sinapine-degrading bacteria from the intestinal tract of laying hens显示文摘This study was aimed to isolate sinapine-degrading bacteria from the intestinal tract of laying hens and to identify the predominant bacteria. Thirty-week old healthy laying hens were killed, and the chyme in the digestive tract was inoculated into modified Czapek medium containing sinapin and cultivated at 37 ℃for 10 days. The optical density(OD) values of the bacterial solutions at different cultivating times were detected by a spectrophotometric method. The predominant strains were identified by 16 S rRNA gene analysis. We extracted the extracellular products of the predominant strains to determine the total protein using the Coomassie brilliant blue method, and to determine the activities of some extracellular enzymes using the agar plate diffusion method. Nine strains were isolated from the lower intestinal tract of laying hens. Among the 9 strains, 5 were from the ileum, 2 were from the ceca and 2 were from the jejunum. We could not isolate any strains from the upper intestinal tract, such as the stomach and duodenum. Eight of those 9 isolated strains were gram negative and one was gram positive. Strains YD-1 and YD-2 were better than other strains in their abilities to degrade sinapine. Strains YD-1 and YD-2 were identified as Escherichia coli and Klebsiella spp., respectively, by the 16 S rRNA sequence analysis.The total protein level of the extracellular products was 1.213 g/L for YD-1 and 1.990 g/L for YD-2. Both extracellular products of YD-1 and YD-2 had the activities of protease, amylase and urease. This study confirmed that the primary site of sinapine degradation is in the lower intestinal tract of laying hens. The sinapine-degrading strains are mainly gram negative. Strains YD-1 and YD-2 are predominant in degrading sinapine and they belong to E. coli and Klebsiella spp., respectively. Both extracellular products of YD-1 and YD-2 contain protease, amylase and urease. Strain YD-2 is better than strain YD-1 in its ability to degrade sinapine. | Dan Yu Xiaoli Huang Chengyi Zou Bin Li Jing Duan Qin Yin | 2016 | Animal Nutrition2016，，1： | 5 |
| 5 | Competition between Populus euphratica and Tamarix ramosissima seedlings under simulated high groundwater availability显示文摘Desert riparian plants experience high variability in water availability due to hydrological fluctuations. How riparian plants can survive with low water availability has been well studied, however, little is known about the effects of high water availability on plant community structuring. We conducted a mesocosm experiment to test whether seedling competition under simulated high groundwater availability can explain the shift of co-dominance of Populus euphratica and Tamarix ramosissima in early communities to P. euphratica dominance in mature ones along the Tarim River in northwestern China. Seedlings of these two plant species were grown in monoculture and mixture pools with high groundwater availability. Results indicated that the above-ground biomass and relative yield of T. ramosissima were higher than those of P. euphratica. The competitive advantages of T. ramosissima included its rapid response in growth to groundwater enrichment and its water spender strategy, as evidenced by the increased leaf biomass proportion and the inert stomatal response to leaf-to-air vapor pressure deficit(VPD). In comparison, P. euphratica showed a conservative strategy in water use, with a sensitive response to leaf-to-air VPD. Result of the short-term competition was inconsistent with the long-term competition in fields, suggesting that competition exclusion is not the mechanism structuring the desert riparian plant communities. Thus, our research highlights the importance of mediation by environmental fluctuations(such as lessening competition induced by disturbance) in structuring plant communities along the Tarim riparian zones. | WU Guilin JIANG Shaowei LIU Weiyang ZHAO Chengyi LI Jun | 2016 | Journal of Arid Land2016，8，2： | 4 |
| 6 | Ternary organic solar cells based on polymer donor,polymer acceptor and PCBM components显示文摘In this work,ternary organic solar cells(OSCs)combining a fullerene derivative PC71BM with a nonfullerene acceptor N2200-F blended with a polymer donor PM6 were reported.Compared with the binary systems,the highest power conversion efficiency(PCE)of 8.11%was achieved in ternary solar cells with 30 wt%N2200-F content,mainly due to the improved short-circuit current density(Jsc)and fill factor(FF).Further studies showed that the improved Jsc could attribute to the complementary abso rption of the two acceptors and the enhanced FF was originated from the higher hole mobility and the fine-tuned morphology in the ternary system.These results demonstrate that the combination of fullere ne and nonfullerene acceptors in ternary organic solar cells is a promising approach to achieve high-performance OSCs. | Feng Liu Cheng Li Junyu Li Chao Wang Chengyi Xiao Yonggang Wu Weiwei Li | 2020 | Chinese Chemical Letters2020，31，3： | 3 |
| 7 | Regional partitioning of agricultural non-point source pollution in China using a projection pursuit cluster model显示文摘A projection pursuit cluster(PPC) model was used to analyze the regional partitioning of agricultural non-point source pollution in China.The environmental factors impacting the agricultural non-point source pollution were compiled into a projection index to set up the projection index function.A novel optimization algorithm called Free search(FS) was introduced to optimize the projection direction of the PPC model.By making the appropriate improvements as we explored the use of the algorithm,it became simpler,and developed better exploration abilities.Thus,the multi-factor problem was converted into a single-factor cluster,according to the projection,which successfully avoided subjective disturbance and produced objective results.The cluster results of the PPC model mirror the actual regional partitioning of the agricultural non-point source pollution in China,indicating that the PPC model is a powerful tool in multi-factor cluster analysis,and could be a new method for the regional partitioning of agricultural non-point source pollution. | XinHu LI ChengYi ZHAO Bin WANG Garry FENG | 2011 | Journal of Arid Land2011，3，4： | 3 |
| 8 | Light-driven artificial muscles based on electrospun microfiber yarns显示文摘Artificial muscles are widely potential in diverse fields including medical treatment, humanoid robotics and industrial automation. Soft materials due to bio-friendly interaction are suitable for those applications. Planar and fiber shape based artificial muscles that use the polymer as substrate materials can be triggered by various stimuli like electric, moisture and heat. Here,artificial muscles based on electrospun microfiber yarns are demonstrated, which can be remotely controlled. The carbon nanotubes embedded in polyurethane microfibers enable the yarns to efficiently absorb near-infrared light and radiate heat,which induces the fast temperature change that leads to the contraction/expansion motions along the axial direction. Microfiber mats are collected by a rotating cylinder that results in highly oriented alignment. The yarns from microfiber mats are highly twisted into the coiled structure, which generates maximum contractive actuation of 6.7% at 70°C. 1000 cycles were demonstrated without an obvious decline of actuating performances. The light-driven artificial muscles can be potentially applied in wireless control, bio-medical devices and so on. | MENG JunXing HOU ChengYi ZHANG QingHong LI YaoGang WANG HongZhi | 2019 | Science China(Technological Sciences)2019，62，6： | 3 |
| 9 | A STUDY ON THE EFFECT OF RADIAL INERTIA ON THE ELASTO-PLASTIC COMBINED STRESS WAVE PROPAGATION IN THIN-WALLED TUBES显示文摘An in-depth analysis of propagation characteristics of elasto-plastic combined stress waves in circular thin-walled tubes has been made. In obtaining the simple-wave solution, however,most researches have ignored the influence of the circumferential stressrelated to the radial inertial effect in the tubes. In this paper the incremental elasto-plastic constitutive relations which are convenient for dynamic numerical analysis are adopted, and the finite-difference method is used to study the evolution and propagation of elasto-plastic combined stress waves in a thin-walled tube with the radial inertial effect of the tube considered. The calculation results are compared with those obtained when the radial inertial effect is not considered. The calculation results show that the radial inertial effect of a tube has a fairly great influence on the propagation of elasto-plastic combined stress waves. | Li Yongchi Huang Chengyi Yuan Fuping Jin Yongmei | 2001 | Acta Mechanica Solida Sinica2001，14，1： | 2 |
| 10 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |

| 14 | Controlled direct synthesis of single- to multiple-layer MWW zeolite显示文摘The minimized diffusion limitation and completely exposed strong acid sites of the ultrathin zeolites make it an industrially important catalyst especially for converting bulky molecules.However,the structure-controlled and large-scale synthesis of the material is still a challenge.In this work,the direct synthesis of the single-layer MWW zeolite was demonstrated by using hexamethyleneimine and amphiphilic organosilane as structure-directing agents.Characterization results confirmed the formation of the single-layer MWW zeolite with high crystallinity and excellent thermal/hydrothermal stability.The formation mechanism was rigorously revealed as the balanced rates between the nucleation/growth of the MWW nanocrystals and the incorporation of the organosilane into the MWW unit cell,which is further supported by the formation of MWW nanosheets with tunable thickness via simply changing synthesis conditions.The commercially available reagents,well-controlled structure and the high catalytic stability for the alkylation of benzene with 1-dodecene make it an industrially important catalyst. | Jie-Qiong Chen Yu-Zhao Li Qing-Qing Hao Huiyong Chen Zhao-Tie Liu Chengyi Dai Jianbo Zhang Xiaoxun Ma Zhong-Wen Liu | 2021 | National Science Review2021，8，7： | 1 |
| 15 | A Soil Morphological Index for Paleosol Research显示文摘We developed a soil morphological index to quantitatively measure the degree ofpaleosol development. For its development, this index combined paleopedogenic features with tensoil macro- and micro-morphological properties from morphological descriptions of Potou and JiuZhoutai loess sections in the Loess Plateau of China. These ten properties are: rubification (colorhue and chroma), total texture (texture type, stickiness and plasticity), melanization (color value),microstructure, fine material (<0.01 mm), primary carbonate, biotite, fe(hydr)oxides, secondarycarbonate (micromorphology) and illuvial clay. Future study may reject some of these propertiesand add others. The index works well with the loess-paleosol sequences. The soil morphologicalindex successfully identifies paleosols and weak-paleosols. | LI Xuyong LI Baoguo GUO Zhengtang ZHAO Chengyi SHI Yuanchun 1 Commission for Integrated Survey of Natural Resources, CAS, Beijing 100101, China. 2 Department of Soil and Water, China Agricultural University, Beijing 100094, China 3 Institute of Geology, CAS, Beijing 100029, China 4 Institute of Xinjiang Ecology and Geography, CAS, Urumqi 830011.

| 16 | Mechanical-robust and recyclable polyimide substrates coordinated with cyclic Ti-oxo cluster for flexible organic solar cells显示文摘With the rapid development of flexible optoelectronic devices,recyclability is highly desirable for alleviating resource waste and environmental pollution,but remains challenging.Here,a fully closed-loop recyclable crosslinked polyimide(RCPI)was fabricated via carboxyl ligand exchange between the CPI with pendent carboxyl groups and the cyclic Ti-oxo cluster(CTOC)with labile carboxyl ligands,which could be reconverted into reprocessable CPI and CTOC solution by pivalic acid.The RCPI-based embedded AgNWs@RCPI electrode shows comparable high conductivity,transparency and low roughness with ITO(indium tin oxide)/glass electrode,and meanwhile outstanding mechanical robustness.The related flexible organic solar cells(FOSCs)provided a high efficiency of 14.78% and maintained~97% of the initial efficiency after 5000 bending cycles at a small bending radius of 1 mm.Moreover,the recyclability of the RCPI still retains after being manufactured into the FOSCs.This work provides a promising strategy for recyclable flexible optoelectronic devices. | Guangcong Zhang Qiaomei Chen Chengcheng Xie Yongmei Wang Chaowei Zhao Chengyi Xiao Yen Wei Weiwei Li | 2022 | npj Flexible Electronics2022，6，1： | 1 |
| 17 | Camera localization for augmented reality and indoor positioning:a vision-based 3D feature database approach显示文摘The recent fast development in computer vision and mobile sensor technology such as mobile LiDAR and RGB-D cameras is pushing the boundary of the technology to suit the need of real-life applications in the fields of Augmented Reality(AR),robotics,indoor GIS and self-driving.Camera localization is often a key and enabling technology among these applications.In this paper,we developed a novel camera localization workflow based on a highly accurate 3D prior map optimized by our RGBD SLAM method in conjunction with a deep learning routine trained using consecutive video frames labeled with high precision camera pose.Furthermore,an AR registration method tightly coupled with a game engine is proposed,which incorporates the proposed localization algorithm and aligns the real Kinetic camera with a virtual camera of the game engine to facilitate AR application development in an integrated manner.The experimental results show that the localization accuracy can achieve an average error of 35 cm based on a fine-tuned prior 3D feature database at 3 cm accuracy compared against the ground-truth 3D LiDAR map.The influence of the localization accuracy on the visual effect of AR overlay is also demonstrated and the alignment of the real and virtual camera streamlines the implementation of AR fire emergency response demo in a Virtual Geographic Environment. | Jing Li Chengyi Wang Xuejie Kang Qiang Zhao | 2020 | International Journal of Digital Earth2020，13，6： | 1 |

| 20 | An iridium(Ⅲ)-palladium(Ⅱ) metal-organic cage for efficient mitochondria-targeted photodynamic therapy显示文摘An Ir8 Pd4-heteronuclear metal-organic cage(MOC-51)was assembled from bipodal metalloligand[Ir(ppy)2(qpy)(BF4)](qpy=4,4′:2′,2″:4″,4′′′-quaterpyridine;ppy-2-phenylpridine)with Pd(Ⅱ)salt.The cubic barrel shaped MOC shows one-photon and two-photon excited deep-red emission,as well as large singlet oxygen quantum yields under visible light irradiation,therefore exhibiting great potentials in organelles-targeted cell imaging and photodynamic therapy(PDT).Compared with the Ir(Ⅲ)metalloligand,the Ir8 Pd4-MOC showed less dark toxicity and higher mitochondria-targeting efficiency.The localization in mitochondria overco mes the limitation of short lifetime and diffusion distance of ROS in cell,thus improved PDT effect can be obtained in low light dose usage of the MOC.This study presents the first case of Ir-based metal-organic cages for bio-applications in successful integration of imaging diagnosis and photodynamic therapy. | Chaojie Li Yaping Wang Yulin Lu Jing Guo Chengyi Zhu Haozhe He Xiaohui Duan Mei Pan Chengyong Su | 2020 | Chinese Chemical Letters2020，31，5： | 1 |
