1A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding.Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu 2020Molecular Plant2020,13,9:14
2Integrative single-cell analysis of transcriptome,DNA methylome and chromatin accessibility in mouse oocytes显示文摘Oocyte growth is a key step in forming mature eggs that are ready to be fertilized.The states and modifications of chromatin represent critical sources of information for this process.However,the dynamics and interrelations of these chromatin characteristics remain elusive.In this study,we developed an improved scCOOL-seq technique (iscCOOL-seq),which is a multiomics,single-cell and single-base resolution method with high mapping rates,and explored the chromatin accessibility landscape and its relationship to DNA methylation in growing mouse oocytes.The most dramatic change in chromatin accessibility occurs during oocyte growth initiation,accompanied with prominent transcriptome alterations and an elevated variation in DNA methylation levels among individual oocytes.Unlike CpG islands (CGIs),partially methylated domains (PMDs)are associated with a low density of nucleosome-depleted regions (NDRs)during the whole maturation period.Surprisingly,highly expressed genes are usually associated with NDRs at their transcriptional end sites (TESs).In addition,genes with de novo methylated gene bodies during oocyte maturation are already open at their promoters before oocyte growth initiation.Furthermore,epigenetic and transcription factors that might be involved in oocyte maturation are identified.Our work paves the way for dissecting the complex, yet highly coordinated,epigenetic alterations during mouse oocyte growth and the establishment of totipotency.Chan Gu Shanling Liu Qihong Wu Lin Zhang Fan Guo 2019Cell Research2019,29,2:14

4Whole-system thinking, development control, key barriers and promotion mechanism for EV development显示文摘Electric vehicles(EVs)have received significant attention because of the potential energy savings and emission reductions they enable.However,current studies and demonstrations have focused mainly on specific technologies and equipment types,which cannot in themselves solve the predicaments facing EVs.This study points out that EVs will form a large,complex system that needs to be optimized over different aspects to compete with traditional vehicles.Therefore,wholesystem thinking is needed to support the development control of EVs,with a broader scope than operational control,and the core issue is the interaction between EVs and power grid,including their coordinated development and operational management.For development control of EVs,a target system and a step-wise optimization method are presented,as well as the basic principles for designing the target system.There are two key barriers in EVs’development:the research and mass production of highperformance power batteries,and the formulation of a favorable mechanism to capture benefits and encourage development.To address the problems of EV development,a promotion method that combines franchising with moderate competition is proposed.The concepts and methods developed in this study can facilitate the research and development of EVs.Chunlin GUO Ching Chuen CHAN 2015Journal of Modern Power Systems and Clean Energy2015,3,2:9
5Estimation and Projection of the HIV Epidemic Trend among the Migrant Population in China显示文摘Objective The migrant population is a vulnerable group for HIV infection in China.Understanding potential epidemic trends among migrants is critical for developing HIV preventative measures in this population.Methods The Estimation and Projection Package (EPP) model was used to process prefecture and county-level surveillance data to generate HIV prevalence and epidemic trends for migrant populations in China.Results The prevalence of HIV among migrants in 2009 was estimated at 0.075% (95% CI:0.042%,0.108%) in China.The HIV epidemic among migrants is likely to increase over the next 5 years,with the prevalence expected to reach 0.110% (95% CI:0.070%,0.150%) by 2015.Conclusion Although the 2009 estimates for the HIV/AIDS epidemic in China indicate a slower rate of increase compared with the national HIV/AIDS epidemic,it is estimated to persistently increase among migrants over the next 5 years.Migrants will have a strong impact on the overall future of the HIV epidemic trend in China and evidence-based prevention and monitoring efforts should be expanded for this vulnerable population.MENGXiaoJun WANG Lu Susan CHAN Kathleen Heather REILLY PENG ZhiHang GUO Wei DING GuoWei DING ZhengWei QIN QianQian 2011Biomedical and Environmental Sciences2011,24,4:8

7Would integrated Western and traditional Chinese medicine have more benefits for stroke rehabilitation? A systematic review and meta-analysis显示文摘Background Stroke is a major cause of death or long-term disability worldwide.Many patients with stroke receive integrative therapy consisting of Western medicine(WM)and routine rehabilitation in conjunction with Chinese medicine(CM),such as acupuncture and Chinese herbal medicine.However,there is no available evidence on the effectiveness of the combined use of WM and CM interventions in stroke rehabilitation.Aims The purpose of this meta-analysis is to evaluate the results of all individual studies to assess the combined use of CM and WM in stroke rehabilitation compared with WM only.Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed.MEDLINE,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI)were searched.The included outcomes were dependency,motor function,depression and swallowing function.Subgroup analysis was performed,and publication bias was assessed using funnel plots.Summary of review 58 studies and 6339 patients were included in the meta-analysis.Subgroup analysis revealed that combined therapy comprising both acupuncture and WM had a superior effect on improving dependency and swallowing function compared with standard WM therapy alone.Potential superiority of combined therapy comprising CM and WM in improving depression compared with standard WM therapy was also found.Conclusions Our results indicate that the combined use of CM and WM could be more efficacious in stroke rehabilitation compared with the use of WM therapy alone.However,most studies were short in duration(2 to 4 weeks)and prone to different types of biases,which prevents making any conclusion regarding the long-term effects and raises concerns regarding true efficacy in context of high likelihood of Hawthorn bias.So,more randomised controlled trials with more rigorous design and longer duration of treatment and follow-up need to be conducted to compare WM alone versus WM and CM combined.Linda LD Zhong Ya Zheng Alexander Y Lau Norman Wong Liang Yao Xingyao Wu Tengteng Shao Zhenxing Lu Huijuan Li Chun Sum Yuen Jianwen Guo Suzanne Lo Janita Chau Kam Wa Chan Bacon Fung Leung Ng Zhaoxiang Bian Edwin Chau-leung Yu 2022Stroke & Vascular Neurology2022,7,1:7
8Adsorptive hemofiltration for sepsis management: expert recommendations based on the Asia Pacific experience显示文摘To the Editor:In sepsis,bacterial endotoxins play a central role by inducing a dysregulated and exaggerated release of inflammatory mediators and cytokines,often described as the“cytokine storm”or“cytokinemia.”[1]Both endotoxins and cytokines have been implicated in the development of organ dysfunction,including acute kidney injury(AKI).[2]Removing circulating endotoxins and excess cytokines from the circulation restores chemotactic gradients,localizing the immune response to the principal site of infection and re-establishing a regulated immune response.[1,3]Therefore,using hemofilters with enhanced endotoxin and cytokine adsorptive properties may bring about additional therapeutic benefits compared with conventional continuous renal replacement therapy(CRRT)filters.Ling Zhang Matthew Cove Binh G.Nguyen Nuttha Lumlertgul Kartik Ganesh Alfred Chan Giang T.H.Bui Chunwen Guo Junhua Li Songqiao Liu Mian Peng Kit W.Foong Jian Zhang Minmin Wang Jacques Goldstein Kai Harenski 2021Chinese Medical Journal2021,,18:6

10Crystal structures of D-psicose 3-epimerase from Clostridium cellulolyticum H10 and its complex with ketohexose sugars显示文摘D-Psicose 3-epimerase(DPEase)is demonstrated to be useful in the bioproduction of D-psicose,a rare hexose sugar,from D-fructose,found plenty in nature.Clostridium cellulolyticum H10 has recently been identified as a DPEase that can epimerize D-fructose to yield D-psicose with a much higher conversion rate when compared with the conventionally used DTEase.In this study,the crystal structure of the C.cellulolyticum DPEase was determined.The enzyme assembles into a tetramer and each subunit shows a(β/α)8 TIM barrel fold with a Mn2+metal ion in the active site.Additional crystal structures of the enzyme in complex with substrates/products(D-psicose,D-fructose,D-tagatose and D-sorbose)were also determined.From the complex structures of C.cellulolyticum DPEase with D-psicose and D-fructose,the enzyme has much more interactions with D-psicose than D-fructose by forming more hydrogen bonds between the substrate and the active site residues.Accordingly,based on these ketohexosebound complex structures,a C3-O3 proton-exchange mechanism for the conversion between D-psicose and D-fructose is proposed here.These results provide a clear idea for the deprotonation/protonation roles of E150 and E244 in catalysis.Hsiu-Chien Chan Yueming Zhu Yumei Hu Tzu-Ping Ko Chun-Hsiang Huang Feifei Ren Chun-Chi Chen Yanhe Ma Rey-Ting Guo Yuanxia Sun 2012Protein & Cell2012,3,2:6

12Investigation of Radix Achyranthis Bidentatae Phytochemistry and Pharmacology显示文摘Radix achyranthis bidentatae(RAB), a member of the Amaranthaceae family, has been widely used in Traditional Chinese Medicine for1000 s of years. Increasing interest in RAB-derived medicinal has led to the discovery of additional triterpenoid saponins, phytoecdysones,polysaccharides, and many other compounds, as well as investigations into their pharmacology. A large number of pharmacological studies have shown RAB and its active components possess a range of pharmacological activities, including anti-tumor, anti-fertility, anti-senile, and anti?inflammatory effects. This review is an up?to?date summary and synthesis of the uses of RAB from phytochemical and pharmacological perspectives.Liu Yang A-Jiao Hou Mei-Ling Yan Xu-Dong Xing Xin-Yue Guo Hai Jiang Bing-You Yang Kelvin Chan Qiu-Hong Wang Hai-Xue Kuang 2019World Journal of Traditional Chinese Medicine2019,5,1:4
13Continuous and comprehensive atmospheric observations in Beijing:a station to understand the complex urban atmospheric environment显示文摘Due to profound impact on climate and human health,air quality has attracted attention from all levels of the civil society.The key step in the provision of required tools for the society to tackle the complex air quality problem is to characterize it in a comprehensive manner with a long-term perspective.Here,we describe a continuous and comprehensive observation station and its accompanying state-ofthe-art instrumentation that was established to investigate the complex urban atmospheric environment in a rapidly developing Chinese Megacity.The station,located in downtown Beijing,aims to study air quality by identifying the major atmospheric pollutants and key processes determining their formation and loss mechanisms.A few hundreds of parameters are continuously measured with the state-of-the-art instruments,including trace gas concentrations,aerosol particle size distributions,and mass concentrations,covering aerosol particle chemical composition from molecules to micrometer-sized aerosol particles.This produced long-term,comprehensive big data with around 1�10^(11)bytes per year.In this paper,we provide an overview on the facilities of the station,the instrumentation used,the workflow of continuous observations and examples of results from 2018 to 2019 and a basis for establishing a modern long-term,comprehensive atmospheric urban observation station in other megacities.Yongchun Liu Chao Yan Zemin Feng Feixue Zheng Xiaolong Fan Yusheng Zhang Chang Li Ying Zhou Zhuohui Lin Yishou Guo Ying Zhang Li Ma Wenshuo Zhou Zhikun Liu Lubna Dada Kaspar Dallenbach Jenni Kontkanen Runlong Cai Tommy Chan Biwu Chu Wei Du Lei Yao Yonghong Wang Jing Cai Juha Kangasluoma Tom Kokkonen Joni Kujansuu Anton Rusanen Chenjuan Deng Yueyun Fu Rujing Yin Xiaoxiao Li Yiqun Lu Yiliang Liu Chaofan Lian Dongsen Yang Weigang Wang Maofa Ge Yuesi Wang Douglas R.Worsnop Heikki Junninen Hong He Veli-Matti Kerminen Jun Zheng Lin Wang Jingkun Jiang Tuukka Petaja Federico Bianchi Markku Kulmala 2020Big Earth Data2020,4,3:3
14Haplotype-resolved genome assembly and allele- specific gene expression in cultivated ginger显示文摘Ginger(Zingiber officinale)is one of the most valued spice plants worldwide;it is prized for its culinary and folk medicinal applications and is therefore of high economic and cultural importance.Here,we present a haplotype-resolved,chromosome-scale assembly for diploid ginger anchored to 11 pseudochromosome pairs with a total length of 3.1 Gb.Remarkable structural variation was identified between haplotypes,and two inversions larger than 15Mb on chromosome 4 may be associated with ginger infertility.We performed a comprehensive,spatiotemporal,genome-wide analysis of allelic expression patterns,revealing that most alleles are coordinately expressed.The alleles that exhibited the largest differences in expression showed closer proximity to transposable elements,greater coding sequence divergence,more relaxed selection pressure,and more transcription factor binding site differences.We also predicted the transcription factors potentially regulating 6-gingerol biosynthesis.Our allele-aware assembly provides a powerful platform for future functional genomics,molecular breeding,and genome editing in ginger.Shi-Ping Cheng Kai-Hua Jia Hui Liu Ren-Gang Zhang Zhi-Chao Li Shan-Shan Zhou Tian-Le Shi Ai-Chu Ma Cong-Wen Yu Chan Gao Guang-Lei Cao Wei Zhao Shuai Nie Jing-Fang Guo Si-Qian Jiao Xue-Chan Tian Xue-Mei Yan Yu-Tao Bao Quan-Zheng Yun Xin-Zhu Wang Ilga Porth Yousry AEl-Kassaby Xiao-Ru Wang Zhen Li Yves Van de Peer Jian-Feng Mao 2021Horticulture Research2021,8,1:3

16A single-cell transcriptome of mesenchymal stromal cells to fabricate bioactive hydroxyapatite materials for bone regeneration显示文摘The osteogenic microenvironment of bone-repairing materials plays a key role in accelerating bone regeneration but remains incompletely defined,which significantly limits the application of such bioactive materials.Here,the transcriptional landscapes of different osteogenic microenvironments,including three-dimensional(3D)hydroxyapatite(HA)scaffolds and osteogenic medium(OM),for mesenchymal stromal cells(MSCs)in vitro were mapped at single-cell resolution.Our findings suggested that an osteogenic process reminiscent of endochondral ossification occurred in HA scaffolds through sequential activation of osteogenic-related signaling pathways,along with inflammation and angiogenesis,but inhibition of adipogenesis and fibrosis.Moreover,we revealed the mechanism during OM-mediated osteogenesis involves the ZBTB16 and WNT signaling pathways.Heterogeneity of MSCs was also demonstrated.In vitro ossification of LRRC75A+MSCs was shown to have better utilization of WNT-related ossification process,and PCDH10+MSCs with superiority in hydroxyapatite-related osteogenic process.These findings provided further understanding of the cellular activity modulated by OM conditions and HA scaffolds,providing new insights for the improvement of osteogenic biomaterials.This atlas provides a blueprint for research on MSC heterogeneity and the osteogenic microenvironment of HA scaffolds and a database reference for the application of bioactive materials for bone regeneration.Peng Guo Xizhe Liu Penghui Zhang Zhongyuan He Zhen Li Mauro Alini RGeoff Richards Sibylle Grad Martin J.Stoddart Guangqian Zhou Xuenong Zou Danny Chan Wei Tian Dafu Chen Manman Gao Zhiyu Zhou Shaoyu Liu 2022Bioactive Materials2022,7,3:3
17Weather Information Acquisition and Health Significance during Extreme Cold Weather in a Subtropical City:A Crosssectional Survey in Hong Kong显示文摘Health and disaster risk reduction are important and necessary components in building a smart city,especially when climate change may increase the frequency of extreme temperatures and the health risks of urban dwellers.However,limited knowledge is available about the best way to disseminate weather warnings and health protection information.This study explores the weather information acquisition patterns of the Hong Kong public and examines the sociodemographic predictors of these patterns to establish the potential public health implications of smart city development.A population-based,stratified crosssectional,random digit dialing telephone survey was conducted among the Cantonese-speaking population aged over 15 years in Hong Kong in early 2016.Analyses were conducted based on 1017 valid samples,with a response rate of 63.6%.Cold Weather Warnings were well disseminated in Hong Kong,with 95.7% of the respondents reporting awareness of the public warnings.Television and smartphone apps were the two most important channels for weather information acquisition.Age and education level are the main social-demographic variables associated with the current utilization and future preference of smartphone technology.Among those who were not using a preferredchannel to acquire weather information,61.3% considered switching to a smartphone app.Moreover,the patterns of individual health protection measures and self-reported health impacts were significantly different between smartphone app users and non-users.Weather information dissemination should be tailored to the sociodemographic characteristics of the users.Emily Ying Yang Chan Zhe Huang Carman Ka Man Mark Chunlan Guo 2017International Journal of Disaster Risk Science2017,8,2:2

20Plasma metabolomics combined with personalized diagnosis guided by Chinese medicine reveals subtypes of chronic heart failure显示文摘Background:Chronic heart failure(CHF)is characterized by insufficient blood supply from heart to meet the body’s metabolic demands.Integrating Western and traditional Chinese medicine to treat CHF has proved a validated therapeutic approach.In recent years,metabolomics has been regarded as a potential platform to provide biomarkers for diseasesubtypes.Objective:To examine 38 patients,combined NMR plasma metabolomics and traditional Chinese medicine diagnosis in order to identify diagnostic biomarkers for two CHF syndrome subtypes.Methods:After processing the spectra,orthogonal partial least square discriminant analysis was performed,and the contributing NMR signals were analyzed using Y-scrambling statistical validation with good reliability.Results:Plasma metabolic patterns of yin deficiency and yang deficiency patients were clearly discriminated.The yin-deficiency group had increased level of lactate,glycoprotein,lipoprotein and lower levels of glucose,valine and proline.The yang-deficiency group had higher levels of lactate,glycoprotein and pyruvic acid,and lower levels of glucose and lipoprotein.Potential biomarkers of CHF based on the two traditional Chinese medicine syndromes indicated alternative modes of metabolites and metabolic pathways in the disease,e.g.dysfunction of energy utilization and disturbance in fatty acids,amino acids.Conclusion:This study suggests that combining metabolomics with traditional Chinese medicine diagnosis can reveal metabolic signatures for CHF syndrome subtypes.The plasma metabolites identified might be of special clinical relevance for subtypes of CHF,which could lead to further understanding of mechanisms involved and an improvement in personalized treatment for CHF.Juan Wang Shuzhen Guo Kuo Gao Qi Shi Bangze Fu Chan Chen Liangtao Luo Dong Deng Huihui Zhao Wei Wang 2015Journal of Traditional Chinese Medical Sciences2015,2,2:2
