2Traditional Chinese medicine in COVID-19显示文摘COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2(SARSCo V-2)has spread across the globe,posing an enormous threat to public health and safety.Traditional Chinese medicine(TCM),in combination with Western medicine(WM),has made important and lasting contributions in the battle against COVID-19.In this review,updated clinical effects and potential mechanisms of TCM,presented in newly recognized three distinct phases of the disease,are summarized and discussed.By integrating the available clinical and preclinical evidence,the efficacies and underlying mechanisms of TCM on COVID-19,including the highly recommended three Chinese patent medicines and three Chinese medicine formulas,are described in a panorama.We hope that this comprehensive review not only provides a reference for health care professionals and the public to recognize the significant contributions of TCM for COVID-19,but also serves as an evidence-based in-depth summary and analysis to facilitate understanding the true scientific value of TCM.Ming Lyu Guanwei Fan Guangxu Xiao Taiyi Wang Dong Xu Jie Gao Shaoqin Ge Qingling Li Yuling Ma Han Zhang Jigang Wang Yuanlu Cui Junhua Zhang Yan Zhu Boli Zhang 2021Acta Pharmaceutica Sinica B2021,11,11:14
3An eco-environmental friendly operation: An effective method to mitigate the harmful blooms in the tributary bays of Three Gorges Reservoir显示文摘Harmful algal blooms, which frequently occur in different tributaries, have become a serious water quality problem of the Three Gorges Reservoir (TGR) since its initial filling. A three-year monitoring campaign from 2008 to 2010 was conducted to identify the controlling factors of algal blooms and effective preventive measures. The following results were obtained: 1) Layered and bidirectional currents, called intrusive density currents, dominate the tributary bays of the TGR year round; 2) continuously increasing water level can make the intruding density current shift from the middle to the surface, and surface intrusive water can reduce the surface water temperature and break the stable stratification of the tributary; 3) the appearing or fading away of algal blooms is closely associated with fluctuations in the TGR water level. Thus, the water level fluctuation patterns of different 'tide-types' may prevent the occurrence of algal blooms in the spring and summer, and the 'stair-type' tides may control autumn blooms during the impounding period. These methods were feasible and effective throughout the actual TGR's operation in 2009 2011. These patterns formed an eco-environmentally friendly operation (EEFO) to mitigate algal blooms. As an in situ treatment with easier operation and less negative impact and loss, compared with chemical and filter-feeding fish methods, the EEFO is currently considered as the most feasible remedial measure to remit the eco-environmental problems at the Three Gorges Dam (TGD).YANG ZhengJian LIU DeFu JI DaoBin XIAO ShangBin HUANG YuLing MA Jun 2013Science China(Technological Sciences)2013,56,6:14
4Study on the velocity structure of the crust in Southwest Yunnan of the north-south seismic belt—Results from the Menghai-Gengma-Lushui deep seismic sounding profile显示文摘Southwest Yunnan, located in the southern segment of the north-south seismic belt, is one of the regions with strong tectonic movement and seismic activity in China. Study on the characteristics of tectonic setting and deep geophysical field in the region is an important issue in basic science. In 2013, we conducted a 600-km-long Menghai-Gengma-Lushui profile of deep seismic wide-angle reflection/refraction and high-resolution seismic refraction in Southwest Yunnan. In this paper, we use 6 groups of clear intracrustal P-wave phases picked from the seismic record sections of 11 shots to build a velocity structure model of basement and 2D crustal P-wave of the region by using finite difference inversion and ray travel time forward fitting technology. The results show that, from south to north, the crust gradually thickens along the profile and its basement shows a significant lateral heterogeneity. In the vicinity of the Nanting River fault, the basement structure shows the character of alternate depressions and uplifts, and the shallowest basement is about 1.0 km. In the vicinity of Tengchong and Lancang, the basement is about 5.0 km deep. The velocity of the middle and lower crust in the region generally increases with the increasing of depth. At the block boundary and beneath the fault tectonic belt, the velocity contours show apparent irregularity and the P-wave velocity changes sharply. In this region, the Moho gradually deepens from south to north with relatively large lateral undulations. The shallowest point of the Moho is located near Menghai at a depth of about 32.0 km. The deepest point of the Moho is located near Tengchong at a depth of about 40.5 km. Between Gengma and Yongde, the Moho shows significantly fast uplifting and depressing with an amplitude of about 4.0 km. Beneath the Nanting River fault, Longling-Ruili fault, Dayingjiang fault and Tengchong volcano, the basement velocity structure, 2D crustal P-wave velocity structure, distribution of average profile velocity and intracrustal interface spreading also show significant changes from the basement to the top of the Moho, indicating that the crustal velocity and medium physical properties beneath the fault tectonic belt are apparently different from the crustal materials on its both sides, which suggests that these faults should be in a certain scale and may extend to the lower crust or the top of the upper mantle. The earthquakes in the region mainly occurred at a depth of 10–20 km, and the seismic activity is related to the intracrustal medium velocity difference and fault belt distribution. The results can serve as the important data of the crust-mantle structure for the analysis of the deep tectonic setting, earthquake precise positioning, seismogenic structure modeling of the seismic activities in Southwest Yunnan, as well as the important reference for the evaluation of seismic hazard and the planning of earthquake disaster mitigation of this region.WANG ShuaiJun LIU BaoJin ZHANG JianShi LIU BaoFeng DUAN YuLing SONG XiangHui DENG XiaoGuo MA CeJun ZANG YiRan 2015Science China Earth Sciences2015,58,12:13
5The changing regional distribution of grain production in China in the 21st century显示文摘This paper examines the changing regional distribution of grain production in China. Based on the analysis of data from county statistics for the period 2000–2003, major differences in the main grain-output regions in China can be observed. The main grain-producing areas have shifted from the south to the north of China. New grain production regions have been also added to western China since the late 1990s. The per capita grain consumption in one third of China’s main grain-producing counties has fallen below 400 kg; most of these areas are located in southern China. In the new millennium, Northeast China, the central-south North China, and the arid and semi-arid regions of Northwest China produced three quarters of the surplus grains. Most of these areas are located in regions susceptible to environmental change. The amount of grain production in these regions shows high fluctuations. It is argued here that further studies of recent environmental changes as well as a risk assessment of China’s food security in main grain-output regions are needed.YIN Peihong FANG Xiuqi TIAN Qing MA Yuling 2006Journal of Geographical Sciences2006,16,4:8
6Identification and field evaluation of the sex pheromone of an invasive pest,the fall webworm Hyphantria cunea in China显示文摘Pheromone gland extracts of the fall webworm,Hyphantria cunea(Lepidoptera:Arctiidae) were analyzed by gas chromatography(GC) and gas chromatography-mass spectrometry(GC-MS).Based on comparison of retention times and mass spectra of synthetic standards,four compounds were identi-fied as(9Z,12Z)-octadecadienal,(9Z,12Z,15Z)-octadecatrienal,(3Z,6Z,9S,10R)-9,10-epoxy-3,6-heneicosadiene and(3Z,6Z,9S,10R)-9,10-epoxy-1,3,6-heneicosatriene with a ratio of 2:33.6:58.4:6.Trapping tests showed that quaternary blend of these compounds was highly attractive to male H.cunea.Unitraps baited with the quaternary blend loading of 200―300 μg on a gray rubber septum were very effective for monitoring H.cunea populations.SU MaoWen FANG YuLing TAO WanQiang YAN GuoZeng MA WanE ZHANG ZhongNing 2008Chinese Science Bulletin2008,53,4:7
7Pre-course student performance prediction with multi-instance multi-label learning显示文摘Dear editor,Studying courses is one of the most basic and important tasks for college students.For each new course,the initial period of learning is crucial for students,and seriously influences subsequent learning activities.However,given a large number of classes in universities,it has become impossible for teachers to keep track of the individual performance of each student.In these circumstances,it is desirable to predict each student’s performance on a certain course prior to its commencement.Yuling MA Chaoran CUI Xiushan NIE Gongping YANG Kashif SHAHEED Yilong YIN 2019Science China(Information Sciences)2019,62,2:5
8Single-cell transcriptome analysis reveals widespread monoallelic gene expression in individual rice mesophyll cells显示文摘Monoallelic gene expression refers to the phenomenon that all transcripts of a gene in a cell are expressed from only one of the two alleles in a diploid organism. Although monoallelic gene expression has been occasionally reported with bulk transcriptome analysis in plants, how prevalent it is in individual plant cells remains unknown. Here, we developed a single-cell RNA-seq protocol in rice and investigated allelic expression patterns in mesophyll cells of indica(93-11) and japonica(Nipponbare) inbred lines, as well as their F1 reciprocal hybrids. We observed pervasive monoallelic gene expression in individual mesophyll cells, which could be largely explained by stochastic and independent transcription of two alleles. By contrast, two mechanisms that were proposed previously based on bulk transcriptome analyses, parent-oforigin effects and allelic repression, were not well supported by our data. Furthermore, monoallelically expressed genes exhibited a number of characteristics, such as lower expression levels, narrower H3K4me3/H3K9ac/H3K27me3 peaks, and larger expression divergences between 93-11 and Nipponbare. Taken together, the development of a single-cell RNA-seq protocol in this study offers us an excellent opportunity to investigate the origins and prevalence of monoallelic gene expression in plant cells.Yingying Han Xiao Chu Haopeng Yu Ying-Ke Ma Xiu-Jie Wang Wenfeng Qian Yuling Jiao 2017Science Bulletin2017,62,19:5
9Straw return increases crop grain yields and K-use efficiency under a maize-rice cropping system显示文摘Straw return is an effective way to improve crop grain yield and potassium(K)use efficiency by increasing soil K content.However,the effects of straw return on soil K supplying capacity,replacement of K fertilizer,and K-use efficiency under maize(Zea mays L.)–rice(Oryza sativa L.)cropping systems are little studied.A two-year field experiment was conducted to determine the physiological determinants of K-use efficiency under straw return with four K fertilization rates.Sr33(straw returned plus 33%of K fertilizer applied)and Sr67(straw returned plus 67%of K fertilizer applied)increased annual crop yields by 1.5%and 3.2%and increased agronomic K-use efficiency by respectively 2.9 and 1.3-fold on average in the two years,compared with the conventional practice S0K100(no straw returned plus normal amounts of K fertilizer applied).The Sr33 and Sr67 treatments resulted in significantly greater equilibrium K concentration ratios(CR0 K)and specifically exchangeable K(KX)values according to quantity/intensity(Q/I)relationship analyses,indicating improvement of the potential soil K supply capacity.However,the Sr67 better maintained the soil exchangeable K level and K balance.The results suggested that K released from maize and rice straw can replace about half of chemical K fertilizer,depending on the available K content in maize–rice cropping system production.Yuling Han Wei Ma Baoyuan Zhou Akram Salah Mingjian Geng Cougui Cao Ming Zhan Ming Zhao 2021The Crop Journal2021,9,1:5
10High-Performance Solid-State Supercapacitors Fabricated by Pencil Drawing and Polypyrrole Depositing on Paper Substrate显示文摘A solid-state powerful supercapacitor(SC) is fabricated with a substrate of Xerox paper. Its current collector based on a foldable electronic circuit is developed by simply pencil drawing. Thin graphite sheets on paper provide effective channels for electron transmission with a low resistance of 95 X sq-1. The conductive organic material of polypyrrole coated on thin graphite sheets acts as the electrode material of the device. The as-fabricated SC exhibits a high specific capacitance of 52.9 F cm-3at a scan rate of 1 m V s-1. An energy storage unit fabricated by three full-charged series SCs can drive a commercial light-emitting diode robustly. This work demonstrated a simple, versatile and costeffective method for paper-based devices.Jiayou Tao Wenzhen Ma Nishuang Liu Xiaoliang Ren Yuling Shi Jun Su Yihua Gao 2015Nano-Micro Letters2015,7,3:4

12The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs.Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou 2023Horticulture Research2023,10,5:3
13Interleukin-25 in sputum as a marker of airway inflammation in children asthma显示文摘Dear Editor,Interleukin-25(IL-25,also called IL-17E)is an important IL-17 family member that helps initialize and regulate type 2 immunity,exerting an important influence on the pathogenesis of asthma(Corrigan et al.,2011;Barlow et al.,2012).Furthermore,it plays a vital role in initiating type 2 innate lymphoid cell activation and maintenance(Tong and Li,2018)and inducing Th2-type cytokine-mediated allergic airway eosinophilia(Morita et al.,2015).IL-25 expression increases in patients with asthma in different types of lung cells,including lung structural cells(such as endothelium and airway epithelium),eosinophils,T-cells,and mast cells.Following allergen exposure,cells in the bronchial submucosa increase and secrete or respond to IL-25(Corrigan et al.,2011).Plasma IL-25 levels increase in patients with asthma and correlate with lung function(Cheng et al.,2014).The association between IL-25 cells and pulmonary function indicates that IL-25 could be used to monitor asthma severity.In some mouse models,epithelial IL-25 cytokines are closely related with a range of airway inflammation modalities,including type 2 cytokine production,airway eosinophil inflammation,mucinous epithelial metaplasia,and airway hyperresponsiveness(AHR)(Suzukawa et al.,2012).Yun Zhang Cuifen Zhao Xiuxia Zhao Qingyu Kong Mingjie Dingi Yuling Han Xiang Ma Lu Cheng 2019Science China(Life Sciences)2019,62,12:3
14Plant multiscale networks:charting plant connectivity by multi-level analysis and imaging techniques显示文摘In multicellular and even single-celled organisms,individual components are interconnected at multiscale levels to produce enormously complex biological networks that help these systems maintain homeostasis for development and environmental adaptation.Systems biology studies initially adopted network analysis to explore how relationships between individual components give rise to complex biological processes.Network analysis has been applied to dissect the complex connectivity of mammalian brains across different scales in time and space in The Human Brain Project.In plant science,network analysis has similarly been applied to study the connectivity of plant components at the molecular,subcellular,cellular,organic,and organism levels.Analysis of these multiscale networks contributes to our understanding of how genotype determines phenotype.In this review,we summarized the theoretical framework of plant multiscale networks and introduced studies investigating plant networks by various experimental and computational modalities.We next discussed the currently available analytic methodologies and multi-level imaging techniques used to map multiscale networks in plants.Finally,we highlighted some of the technical challenges and key questions remaining to be addressed in this emerging field.Xi Zhang Yi Man Xiaohong Zhuang Jinbo Shen Yi Zhang Yaning Cui Meng Yu Jingjing Xing Guangchao Wang Na Lian Zijian Hu Lingyu Ma Weiwei Shen Shunyao Yang Huimin Xu Jiahui Bian Yanping Jing Xiaojuan Li Ruili Li Tonglin Mao Yuling Jiao Sodmergen Haiyun Ren Jinxing Lin 2021Science China(Life Sciences)2021,64,9:3
15RNA modifications:importance in immune cell biology and related diseases显示文摘RNA modifications have become hot topics recently.By influencing RNA processes,including generation,transportation,function,and metabolization,they act as critical regulators of cell biology.The immune cell abnormality in human diseases is also a research focus and progressing rapidly these years.Studies have demonstrated that RNA modifications participate in the multiple biological processes of immune cells,including development,differentiation,activation,migration,and polarization,thereby modulating the immune responses and are involved in some immune related diseases.In this review,we present existing knowledge of the biological functions and underlying mechanisms of RNA modifications,including N6-methyladenosine(m^(6)A),5-methylcytosine(m^(5)C),N1-methyladenosine(m1 A),N7-methylguanosine(m^(7)G),N4-acetylcytosine(ac^(4)C),pseudouridine(Ψ),uridylation,and adenosine-to-inosine(A-to-I)RNA editing,and summarize their critical roles in immune cell biology.Via regulating the biological processes of immune cells,RNA modifications can participate in the pathogenesis of immune related diseases,such as cancers,infection,inflammatory and autoimmune diseases.We further highlight the challenges and future directions based on the existing knowledge.All in all,this review will provide helpful knowledge as well as novel ideas for the researchers in this area.Lian Cui Rui Ma Jiangluyi Cai Chunyuan Guo Zeyu Chen Lingling Yao Yuanyuan Wang Rui Fan Xin Wang Yuling Shi 2022Signal Transduction and Targeted Therapy2022,7,10:2
16Multi-task MIML learning for pre-course student performance prediction显示文摘In higher education,the initial studying period of each course plays a crucial role for students,and seriously influences the subsequent learning activities.However,given the large size of a course’s students at universities,it has become impossible for teachers to keep track of the performance of individual students.In this circumstance,an academic early warning system is desirable,which automatically detects students with difficulties in learning(i.e.,at-risk students)prior to a course starting.However,previous studies are not well suited to this purpose for two reasons:1)they have mainly concentrated on e-learning platforms,e.g.,massive open online courses(MOOCs),and relied on the data about students’online activities,which is hardly accessed in traditional teaching scenarios;and 2)they have only made performance prediction when a course is in progress or even close to the end.In this paper,for traditional classroom-teaching scenarios,we investigate the task of pre-course student performance prediction,which refers to detecting at-risk students for each course before its commencement.To better represent a student sample and utilize the correlations among courses,we cast the problem as a multi-instance multi-label(MIML)problem.Besides,given the problem of data scarcity,we propose a novel multi-task learning method,i.e.,MIML-Circle,to predict the performance of students from different specialties in a unified framework.Extensive experiments are conducted on five real-world datasets,and the results demonstrate the superiority of our approach over the state-of-the-art methods.Yuling Ma Chaoran Cui Jun Yu Jie Guo Gongping Yang Yilong Yin 2020Frontiers of Computer Science2020,14,5:1
