| 4 | Omentin-1 prevents inflammation-induced osteoporosis by downregulating the pro-inflammatory cytokines显示文摘Osteoporosis is a frequent complication of chronic inflammatory diseases and increases in the pro-inflammatory cytokines make an important contribution to bone loss by promoting bone resorption and impairing bone formation. Omentin-1 is a newly identified adipocytokine that has anti-inflammatory effects, but little is known about the role of omentin-1 in inflammatory osteoporosis. Here we generated global omentin-1 knockout(omentin-1^(-/-)) mice and demonstrated that depletion of omentin-1 induces inflammatory bone loss-like phenotypes in mice, as defined by abnormally elevated pro-inflammatory cytokines, increased osteoclast formation and bone tissue destruction, as well as impaired osteogenic activities. Using an inflammatory cell model induced by tumor necrosis factor-α(TNF-α), we determined that recombinant omentin-1 reduces the production of proinflammatory factors in the TNF-α-activated macrophages, and suppresses their anti-osteoblastic and pro-osteoclastic abilities. In the magnesium silicate-induced inflammatory osteoporosis mouse model, the systemic administration of adenoviral-delivered omentin-1 significantly protects from osteoporotic bone loss and inflammation. Our study suggests that omentin-1 can be used as a promising therapeutic agent for the prevention or treatment of inflammatory bone diseases by downregulating the proinflammatory cytokines. | Shan-Shan Rao Yin Hu Ping-Li Xie Jia Cao Zhen-Xing Wang Jiang-Hua Liu Hao Yin Jie Huang Yi-Juan Tan Juan Luo Ming-Jie Luo Si-Yuan Tang Tuan-Hui Chen Ling-Qing Yuan Er-Yuan Liao Ran Xu Zheng-Zhao Liu Chun-Yuan Chen Hui Xie | 2018 | Bone Research2018，6，2： | 16 |
| 5 | Great progress in study on aerosol and its impact on the global environment显示文摘The transport from atmosphere is a more important pathway than that from rivers for certain elements and compounds in the remote ocean. The desert and those arid/semi-arid areas in the northwest of China and the Loess Plateau are the sources of those aerosols over the Pacific. Atmospheric iron is the limiting factor of the productivity in certain ocean regions. The dust storms must now be seen as repeated sources of pollution elements as well as soil elements to the East China Sea and, farther out, to the North Pacific Ocean and even to the USA. The long-range transport of aerosols, especially the dust storm, from China and the positive feedbacks of iron coupled with sulfur in atmosphere might be one of the important mechanisms that would affect the primary productivity in the Pacific and/or the global climate change and deserve to be further studied. It can be seen clearly that the dust storms would affect not only the health of human beings and the local or regional climate, but also the global climate change that has been the focus of environmental study internationally. | ZHUANG Guoshun, HUANG Ronghui, WANG Mingxing, Q.

| 6 | MicroTom Metabolic Network: Rewiring Tomato Metabolic Regulatory Network throughout the Growth Cycle显示文摘Tomato(Solanum lycopersicum)is a major horticultural crop worldwide and has emerged as a preeminent model for metabolic research.Although many research efforts have focused on the analysis of metabolite differences between varieties and species,the dynamics of metabolic changes during the tomato growth cycle and the regulatory networks that underlie these changes are poorly understood.In this study,we integrated high-resolution spatio-temporal metabolome and transcriptome data to systematically explore the metabolic landscape across 20 major tomato tissues and growth stages.In the resulting MicroTom Metabolic Network,the 540 detected metabolites and their co-expressed genes could be divided into 10 distinct clusters based on their biological functions.Using this dataset,we constructed a global map of the major metabolic changes that occur throughout the tomato growth cycle and dissected the underlying regulatory network.In addition to verifying previously well-established regulatory networks for important metabolites,we identified novel transcription factors that regulate the biosynthesis of important secondary metabolites such as steroidal glycoalkaloids and flavonoids.Our findings provide insights into spatiotemporal changes in tomato metabolism and generate a valuable resource for the study of metabolic regulatory processes in model plants. | Yan Li Yang Chen Lu Zhou Shengjie You Heng Deng Ya Chen Saleh Alseekh Yong Yuan Rao Fu Zixin Zhang Dan Su Alisdair R.Fernie Mondher Bouzayen Tao Ma Mingchun Liu Yang Zhang | 2020 | Molecular Plant2020，13，8： | 10 |
| 7 | Thermal history of the Sichuan Basin,SW China:Evidence from deep boreholes显示文摘The Sichuan Basin is a superimposition basin composed of terrestrial and marine sediments that is well known for its abundant petroleum resources. Thermal history reconstruction using paleogeothermal indicators, including vitrinite reflectance and thermochronological data, shows that different structural subsections of the Sichuan Basin have experienced various paleogeothermal episodes since the Paleozoic. The lower structural subsection comprising the Lower Paleozoic to Middle Permian(Pz–P_2) successions experienced a high paleogeothermal gradient(23.0–42.6°C/km) at the end of the Middle Permian(P_2), whereas the upper structural subsection comprising Late Permian to Mesozoic strata underwent a relatively lower paleogeothermal gradient(13.2–26.9°C/km) at the beginning of the denudation(Late Cretaceous or Paleocene in the different regions). During the denudation period, the Sichuan Basin experienced a successive cooling episode. The high paleogeothermal gradient resulted from an intensive thermal event correlated to the Emeishan mantle plume. The heat flow value reached 124.0 m W/m^2 in the southwestern basin near the center of the Emeishan large igneous province. The low geothermal gradient episode with heat flow ranging from 31.2 to 70.0 m W/m^2 may be related to the foreland basin evolution. The cooling event is a result of the continuous uplift and denudation of the basin. | ZHU Chuan Qing HU ShengBiao QIU NanSheng RAO Song YUAN YuSong | 2016 | Science China Earth Sciences2016，59，1： | 9 |
| 8 | Outcomes in children with biliary atresia following liver transplantation显示文摘BACKGROUND: Congenital biliary atresia is a rare condition characterized by idiopathic dysgenesis of the bile ducts. If untreated, congenital biliary atresia leads to liver cirrhosis, liver failure and premature death. The present study aimed to evaluate the outcomes of orthotopic liver transplantation in children with biliary atresia. METHOD: We retrospectively analyzed 45 patients with biliary atresia who had undergone orthotopic liver transplantation from September 2006 to August 2012. RESULTS: The median age of the patients was 11.0 months (5-102). Of the 45 patients, 41 were younger than 3 years old. Their median weight was 9.0 kg (4.5-29.0), 34 of the 45 patients were less than 10 kg. Thirty-one patients had undergone Kasai portoenterostomy prior to orthotopic liver transplantation. We performed 30 living donor liver transplants and 15 split liver transplants. Six patients died during a follow-up. The median follow-up time of surviving patients was 11.4 months (1.4-73.7). The overall 1-, 2- and 3-year survival rates were 88.9%, 84.4% and 84.4%, respectively. CONCLUSION: With advances in surgical techniques and management, children with biliary atresia after liver transplantation can achieve satisfactory survival in China, although there remains a high risk of complications in the early postoperative period. | Li-Ying Sun Yun-Sheng Yang Zhi-Jun Zhu Wei Gao Lin Wei Xiao-Ye Sun Wei Qu Wei Rao Zhi-Gui Zeng Chong Dong Jin-Peng Tu Jian Wang Yi-He Liu Yuan Liu Li-Xin Yu Yu Wang Jing Li Zhong-Yang Shen | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，2： | 8 |

| 10 | The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |

| 17 | A Multi-semantics Classification Method Based on Deep Learning for Incredible Messages on Social Media显示文摘How to classify incredible messages has attracted great attention from academic and industry nowadays.The recent work mainly focuses on one type of incredible messages(a.k.a rumors or fake news)and achieves some success to detect them.The existing problem is that incredible messages have different types on social media,and rumors or fake news cannot represent all incredible messages.Based on this,in the paper,we divide messages on social media into five types based on three dimensions of information evaluation metrics.And a novel method is proposed based on deep learning for classifying the five types of incredible messages on social media.More specifically,we use attention mechanism to obtain deep text semantic features and strengthen emotional semantics features,meanwhile,construct universal metadata as auxiliary features,concatenating them for incredible messages classification.A series of experiments on two representative real-world datasets demonstrate that the proposed method outperforms the state-of-the-art methods. | WU Lianwei RAO Yuan YU Hualei WANG Yiming AMBREEN Nazir | 2019 | Chinese Journal of Electronics2019，28，4： | 4 |
| 18 | Load balancing routing for single-layered satellite networks显示文摘The varying population density leads to imbalanced utilization rate of satellites. To ensure an intelligent engineering of traffic over satellite networks,a distributed routing scheme for single-layered satellite network,load balancing routing protocol based on mobile agent (LBRP-MA) is proposed. For LBRP-MA,mobile agents explore route by migrating autonomously. Upon arriving at destination,mobile agents migrate back. On each intermediate satellite,mobile agents evaluate path cost considering satellite geographical position as well as inter-satellite link (ISL) cost,and finally take ISL congestion index into account to update routing tables. Through simulations on the Courier-like constellation,the proposed approach is shown to achieve guaranteed end-to-end delay bound and decrease packet loss ratio with better throughput,which is especially suitable for data transferring in case of high traffic load. Moreover,results of the complexity analysis demonstrate that LBRP-MA can have low onboard signaling,storage and computation requirements. Furthermore,issues of LBRP-MA such as ISL congestion index and cost modification factor are discussed. | RAO Yuan WANG Ru-chuan XU Xiao-long | 2010 | The Journal of China Universities of Posts and Telecommunications2010，17，2： | 3 |

| 20 | Morphological Evolution of Fe-Rich Phases in the AlSi_9Cu_3Mg_(0.19)(Fe)Alloy with the Addition of Minor Mn and Cr显示文摘The morphological evolution of Fe-rich phases in the Alalloy has been investigated with various contents of Fe,Mn,and Cr.The results show that coarse Chinese script Fe-rich phases appear in the alloy with 0.6 wt%Fe combined with trace Mn,while the blocky Fe-rich phases appear combined with trace Cr.Under the coexistence of trace Mn and Cr,a large number of fine Chinese script Fe-rich phases could be visible in the low iron-bearing AlSi_9Cu_3-alloy(0.60 wt%).At high Fe level(1.30 wt%),numerous Fe-rich phases with hexagonal morphologies are observed with the trace Cr,while fish-bone and pentagonal morphologies of Fe-rich phases could be simultaneously observed with the addition of both Mn and Cr.The results reveal that the trace Mn and Cr promote the morphological evolution of Fe-rich phases.The morphology evolution mechanism of Fe-rich phases has been discussed by using the atom radius and electronegativity differences of Fe,Mn,and Cr. | Zhi-Qiang Qiu Xiang-Chen Meng Qiu-Hong Yuan Xiao-Shu Zeng Xi-Xin Rao Yan Ding Lan Luo Yong Liu | 2018 | Acta Metallurgica Sinica(English Letters)2018，31，6： | 3 |
