| 1 | Construction of habitat suitability models(HSMs) for benthic macroinvertebrate and their applications to instream environmental flows:A case study in Xiangxi River of Three Gorges Reservior region,China显示文摘Based on a long-term ecological monitoring, the present study chose the most dominant benthic macroinvertebrate (Baetis spp.) as tar- get organisms in Xiangxi River, built the habitat suitability models (HSMs) for water depth, current velocity and substrate, respectively, which is the first aquatic organisms model for habitat suitability in the Chinese Mainland with a long-term consecutive in situ measurement. In order to protect the biointegrity and function of the river ecosystem, the theory system of instream environmental flow should be cat- egorized into three hierarchies, namely minimum required instream flow (hydrological level), minimum instream environmental flow (bio- species level), and optimum instream environmental flow (ecosystem level). These three hierarchies of instream environmental flow models were then constructed with the hydrological and weighted usable area (WUA) method. The results show that the minimum required instream flow of Xiangxi River calculated by the Tennant method (10% of the mean annual flow) was 0.615 m3 s 1; the minimum instream environmental flow accounted for 19.22% of the mean annual flow (namely 1.182 m3 s 1), which was the damaged river channel flow in the dry season; and 42.91% of the mean annual flow (namely 2.639 m3 s 1) should be viewed as the optimum instream environmental flow in order to protect the health of the river ecosystem, maintain the instream biodiversity, and reduce the impact of small hydropower stations nearby the Xiangxi River. We recommend that the hydrological and biological methods can help establish better instream environmental flow models and design best management practices for use in the small hydropower station project. | Fengqing Li Qinghua Cai Xiaocheng Fu Jiankang Liu | 2009 | Progress in Natural Science:Materials International2009，19，3： | 18 |
| 2 | Isotope Chronology and Geochemistry of the Lower Carboniferous Granite in Xilinhot, Inner Mongolia, China显示文摘Geochronological and geochemical analyses were performed on K-feldspar granites and monzonitic granites from the Xilinhot area, Inner Mongolia, China. Zircon U/Pb ages indicate that the two types granites were emplaced during the Lower Carboniferous. The K-feldspar granites(332 Ma) have the typical A-type granite characteristics of a post-collision setting. The monzonitic granites have an emplacement age of 323 Ma. Zircon εHf values of the former range from +12.8 to +14.2, with an average T_(DM2) of 453 Ma. The latter have lower zircon ε_(Hf) values, ranging from +5.4 to +10.7, with an average T_(DM2) of 798 Ma. The strong, positive ε_(Hf) values of the zircon indicate that both sets of samples are from a juvenile crust formed in an oceanic crust subduction stage, although the monzonitic granite may have undergone a hybridization of crustal materials. These results indicate a younger post orogenic event. The Paleo-Asian Ocean had closed before the Early Carboniferous and the Xilinhot area started its post-orogenic evolution with an extensional tectonic environment during the Early Carboniferous. | Xiaocheng Zhao Wenxiao Zhou Dong Fu Bo Huang Mengchun Ge | 2018 | Journal of Earth Science2018，29，2： | 8 |

| 4 | The Solar Upper Transition Region Imager(SUTRI)Onboard the SATech-01 Satellite显示文摘The Solar Upper Transition Region Imager(SUTRI)onboard the Space Advanced Technology demonstration satellite(SATech-01),which was launched to a Sun-synchronous orbit at a height of~500 km in 2022 July,aims to test the on-orbit performance of our newly developed Sc/Si multi-layer reflecting mirror and the 2k×2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of~3 nm.SUTRI employs a Ritchey-Chrétien optical system with an aperture of 18 cm.The on-orbit observations show that SUTRI images have a field of view of~416×416 and a moderate spatial resolution of~8″without an image stabilization system.The normal cadence of SUTRI images is 30 s and the solar observation time is about16 hr each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period.Approximately15 GB data is acquired each day and made available online after processing.SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of~0.5 MK in the solar atmosphere,which has rarely been sampled by existing solar imagers.SUTRI observations will establish connections between structures in the lower solar atmosphere and corona,and advance our understanding of various types of solar activity such as flares,filament eruptions,coronal jets and coronal mass ejections. | Xianyong Bai Hui Tian Yuanyong Deng Zhanshan Wang Jianfeng Yang Xiaofeng Zhang Yonghe Zhang Runze Qi Nange Wang Yang Gao Jun Yu Chunling He Zhengxiang Shen Lun Shen Song Guo Zhenyong Hou Kaifan Ji Xingzi Bi Wei Duan Xiao Yang Jiaben Lin Ziyao Hu Qian Song Zihao Yang Yajie Chen Weidong Qiao Wei Ge Fu Li Lei Jin Jiawei He Xiaobo Chen Xiaocheng Zhu Junwang He Qi Shi Liu Liu Jinsong Li Dongxiao Xu Rui Liu Taijie Li Zhenggong Feng Yamin Wang Chengcheng Fan Shuo Liu Sifan Guo Zheng Sun Yuchuan Wu Haiyu Li Qi Yang Yuyang Ye Weichen Gu Jiali Wu Zhe Zhang Yue Yu Zeyi Ye Pengfeng Sheng Yifan Wang Wenbin Li Qiushi Huang Zhong Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，6： | 1 |

| 6 | Method for the extraction of circulating nucleic acids based on MOF reveals cell-free RNA signatures in liver cancer显示文摘Cell-free RNA(cf RNA) allows assessment of health, status, and phenotype of a variety of human organs and is a potential biomarker to non-invasively diagnose numerous diseases. Nevertheless, there is a lack of highly efficient and bias-free cf RNA isolation technologies due to the low abundance and instability of cf RNA.Here, we developed a reproducible and high-efficiency isolation technology for different types of cell-free nucleic acids(containing cf RNA and viral RNA) in serum/plasma based on the inclusion of nucleic acids by metal-organic framework(MOF) materials, which greatly improved the isolation efficiency and was able to preserve RNA integrity compared with the most widely used research kit method. Importantly, the quality of cf RNA extracted by the MOF method is about 10-fold that of the kit method, and the MOF method isolates more than three times as many different RNA types as the kit method. The whole transcriptome mapping characteristics of cf RNA in serum from patients with liver cancer was described and a cf RNA signature with six cf RNAs was identified to diagnose liver cancer with high diagnostic efficiency(area under curve = 0.905 in the independent validation cohort) using this MOF method. Thus, this new MOF isolation technique will advance the field of liquid biopsy, with the potential to diagnose liver cancer. | Yuqing Sun Haixin Yu Shaoqing Han Ruoxi Ran Ying Yang Yongling Tang Yuhao Wang Wenhao Zhang Heng Tang Boqiao Fu Boshi Fu Xiaocheng Weng Song-Mei Liu Hexiang Deng Shuang Peng Xiang Zhou | 2024 | National Science Review2024，11，1： | 0 |
| 7 | Neofusicoccum parvum Causing Leaf Spot of Camellia drupifera in China显示文摘[Objectives]The study was to identify the causal agent of leaf spots of Camellia drupifera in Hainan Province,China.[Methods]Phylogenetic analyses,spore morphology and pathogenicity tests were adopted to identify the pathogen.[Results]The fungus was identified as Neofusicoccum parvum.The colonies were initially pale to white on PDA,with diffuse yellow pigment around the colonies in the agar after 5 d.After 10 d,the aerial mycelium became gray,and the substrate mycelium became black.Thirty days later,a large number of conidia were generated on OMA.Conidia were hyaline,nonseptate,and fusiform.The mean size of 100 conidia was(13.6-25.4)×(6.2-10.3)μm;the mean length/width ratio was(2.5±0.3)μm.[Conclusions]N.parvum was the causal agent of leaf spots of C.drupifera observed in Hainan Province,China. | Fengyu YU Xiaoyu LIU Xiaocheng JIA Dengqiang FU Xiaoqing NIU Weiwei SONG | 2022 | Plant Diseases and Pests2022，13，2： | 0 |
| 8 | Epidemiological Analysis of Foodborne Botulism Outbreaks-China,2004-2020显示文摘Introduction:Foodborne botulism is a rare,potentially fatal illness resulting from the ingestion of foods contaminated with preformed botulinum neurotoxin types A,B,E,or F,produced by Clostridium botulinum.The descriptive epidemiology of foodborne botulism outbreaks in China during 2004−2020 was performed to inform public health response strategies.Methods:Data from 22 of 31 provincial-level administrative divisions(PLADs)of the National Foodborne Disease Outbreaks Surveillance System during 2004−2020 and Embase,China National Knowledge Infrastructure(CNKI),Wanfang Data,and Chinese Science and Technique Journals(CQVIP)from January 2004 to December 2020 to identify indexed publications in the Chinese literature using the following search terms“botulism,”or“botulinum toxin,”or“Clostridium botulinum.”The number and proportion of outbreaks,illnesses,and deaths by PLAD,food types,and contributing factors were calculated.Results:During 2004−2020,a total of 80 foodborne botulism outbreaks occurred in China,involving 386 illnesses and 55 deaths;most outbreaks were reported between June and August,with a sharp peak in January;22 out of 31 PLADs reported foodborne botulism outbreaks,Xinjiang reported the largest number of outbreaks(20),followed by Qinghai(13);the most commonly implicated foods were homeprepared traditional processed stinky tofu and dried beef,accounting for 51.25%events.Improper processing and improper storage in contributing factors accounted for 77.50%outbreaks.Initial misdiagnosis occurred in 27.50%of cases.Conclusions:Outbreaks of foodborne botulism had a high case-fatality rate.Targeted food safety and popularization education to farmers and herdsmen in Xinjiang and Qinghai related to botulism prevention should be carried out,and timely outbreak investigation and hospital surge capacity should be improved. | Hongqiu Li Yunchang Guo Tian Tian Wanhua Guo Changqing Liu Xiaocheng Liang Jikai Liu Weiwei Li Ping Fu | 2022 | China CDC weekly2022，4，35： | 0 |
