1Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased.NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng 2012Chinese Science Bulletin2012,57,22:51
2The Genome Sequence Archive Family: Toward Explosive Data Growth and Diverse Data Types显示文摘The Genome Sequence Archive(GSA)is a data repository for archiving raw sequence data,which provides data storage and sharing services for worldwide scientific communities.Considering explosive data growth with diverse data types,here we present the GSA family by expanding into a set of resources for raw data archive with different purposes,namely,GSA(https://ngdc.cncb.ac.cn/gsa/),GSA for Human(GSA-Human,https://ngdc.cncb.ac.cn/gsa-human/),and Open Archive for Miscellaneous Data(OMIX,https://ngdc.cncb.ac.cn/omix/).Compared with the 2017 version,GSA has been significantly updated in data model,online functionalities,and web interfaces.GSA-Human,as a new partner of GSA,is a data repository specialized in human genetics-related data with controlled access and security.OMIX,as a critical complement to the two resources mentioned above,is an open archive for miscellaneous data.Together,all these resources form a family of resources dedicated to archiving explosive data with diverse types,accepting data submissions from all over the world,and providing free open access to all publicly available data in support of worldwide research activities.Tingting Chen Xu Chen Sisi Zhang Junwei Zhu Bixia Tang Anke Wang Lili Dong Zhewen Zhang Caixia Yu Yanling Sun Lianjiang Chi Huanxin Chen Shuang Zhai Yubin Sun Li Lan Xin Zhang Jingfa Xiao Yiming Bao Yanqing Wang Zhang Zhang Wenming Zhao 2021Genomics, Proteomics & Bioinformatics2021,19,4:38
3The first all-season sample set for mapping global land cover with Landsat-8 data显示文摘We report the world's first all-season training and validation sample sets for global land cover classification with Landsat-8 data.Prior to this,such samples were only available at a single date primarily from the growing season.It is unknown how much limitation such a single-date sample has to mapping global land cover in other seasons of the year.To answer this question,we selected available Landsat-8 images from four seasons and collected training and validation samples from them.We compared the performances of training samples in different seasons using Random Forest algorithm.We found that the use of training samples from any individual season would result in the best overall classification accuracy when validated by samples in the same season.The global overall accuracy from combined best seasonal results was 67.2% when classifying the 11 Level-1 classes in the Finer Resolution Observation and Monitoring of Global Land Cover(FROM-GLC) classification system.The use of training samples from all seasons(named all-season training sample set hereafter) produced an overall accuracy of 67.0%.We also tested classification within 10° latitude 60° longitude zones using all-season training subsample within each zone and obtained an overall accuracy of 70.2%.This indicates that properly grouped subsamples in space can help improve classification accuracies.All the results in this study seem to suggest that it is possible to use an all-season training sample set to reach global optimality with universal applicability in classifying images acquired at any time of a year for global land cover mapping.Congcong Li Peng Gong Jie Wang Zhiliang Zhu Gregory S.

4Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show 2020Cell Research2020,30,10:19
5Characteristics of the water-soluble components of aerosol particles in Hefei,China显示文摘Size-classified daily aerosol mass concentrations and concentrations of water-soluble inorganic ions were measured in Hefei,China,in four representative months between September 2012 and August 2013.An annual average mass concentration of 169.09μg/m^3 for total suspended particulate(TSP)was measured using an Andersen Mark-II cascade impactor.The seasonal average mass concentration was highest in winter(234.73μg/m^3)and lowest in summer(91.71μg/m^3).Water-soluble ions accounted for 59.49%,32.90%,48.62%and 37.08%of the aerosol mass concentration in winter,spring,summer,and fall,respectively,which indicated that ionic species were the primary constituents of the atmospheric aerosols.The four most abundant ions were NO_3^-,SO_4^(2-),Ca^(2+) and NH_4^+.With the exception of Ca^(2+),the mass concentrations of water-soluble ions were in an intermediate range compared with the levels for other Chinese cities.Sulfate,nitrate,and ammonium were the dominant fine-particle species,which were bimodally distributed in spring,summer and fall;however,the size distribution became unimodal in winter,with a peak at 1.1–2.1μm.The Ca^(2+) peak occurred at approximately 4.7–5.8μm in all seasons.The cation to anion ratio was close to 1.4,which suggested that the aerosol particles were alkalescent in Hefei.The average NO_3^-/SO_4^(2-)mass ratio was 1.10 in Hefei,which indicated that mobile source emissions were predominant.Significant positive correlation coefficients between the concentrations of NH_4^+ and SO_4^(2-),NH_4^+ and NO_3^-,SO_4^(2-)and NO_3^-,and Mg^(2+) and Ca^(2+) were also indicated,suggesting that aerosol particles may be present as(NH_4)_2SO_4,NH_4HSO_4,and NH_4NO_3.Xue-liang Deng Chun-e Shi Bi-wen Wu Yuan-jian Yang Qi Jin Hong-lei Wang Song Zhu Caixia Yu 2016Journal of Environmental Sciences2016,28,4:18
6Ablative fractional CO_(2)laser surgery improving sleep quality,pain and pruritus in adult hypertrophic scar patients:a prospective cohort study显示文摘Background:Poor sleep quality is associated with a decrease in quality of life in patients with major burn scars,combined with pruritus and pain.Few interventions have been reported to improve the sleep quality of patients with scars.In the current prospective cohort study,we investigated the efficacy of CO_(2)-ablative fractional laser(AFL)surgery vs conventional surgery in post-burn patients with hypertrophic scars with sleep quality as the primary study outcome.Methods:In total 68 consecutive patients undergoing scar surgical treatment were recruited,including a CO_(2)-AFL surgery cohort(n=35)and a conventional surgery cohort(n=33).A subgroup from the AFL cohort was selected.Sleep quality,pain and pruritus were evaluated.Multiple linear regression analyses were performed to reveal the effect of CO_(2)-AFL surgery.Results:The CO_(2)-AFL surgery cohort had significantly lower Pittsburgh sleep quality index(PSQI)global scores than the conventional surgery cohort after the last surgical treatment.In the subgroup of patients receiving hardware sleep monitoring,CO_(2)-AFL markedly increased deep sleep time,deep sleep efficiency and reduced initial sleep latency.Compared to the conventional surgery cohort,the CO_(2)-AFL cohort presented significantly lower pain and pruritus scores.Correlation analysis showed pain and pruritus were significantly associated with PSQI scores,and there were also significant correlations between pain and pruritus scores.Multiple linear regression analysis showed that surgery method was negatively linearly correlated with visual analog scale(VAS)pain score,brief pain inventory(BPI)total,VAS pruritus score,5-D itch scale total,four-item itch questionnaire(FIIQ)total and PSQI total.Conclusions:CO_(2)-AFL surgery significantly improved sleep quality and reduced pain and pruritus of hypertrophic scar patients.The alleviation of sleep disorder was associated with improvement of deep sleep quality including deep sleep time and deep sleep deficiency.Trial registration:The Chinese Clinical Trial Registry(ChiCTR200035268)approved retrospectively registration on 5 Aug 2020.Kaiyang Lv Huazhen Liu Haiting Xu Caixia Wang Shihui Zhu Xiaozhen Lou Pengfei Luo Shichu Xiao Zhaofan Xia 2021Burns & Trauma2021,9,1:4
7Distinct immune signatures discriminate between asymptomatic and presymptomatic SARS-CoV-2^(pos)subjects显示文摘Increasing numbers of SARS-CoV-2-positive(SARS-CoV-2^(pos))subjects are detected at silent SARS-CoV-2 infection stage(SSIS).Yet,SSIS represents a poorly examined time-window wherein unknown immunity patterns may contribute to the fate determination towards persistently asymptomatic or overt disease.Here,we retrieved blood samples from 19 asymptomatic and 12 presymptomatic SARS-COV-2^(pos)subjects,47 age/gender-matched patients with mild or moderate COVID-19 and 27 normal subjects,and interrogated them with combined assays of 44-plex CyTOF,RNA-seq and Olink.Notably,both asymptomatic and presymptomatic subjects exhibited numerous readily detectable immunological alterations,while certain parameters including more severely decreased frequencies of CD107a^(low)classical monocytes,intermediate monocytes,non-classical monocytes and CD62L^(hi)CD8^(+)Tnaive cells,reduced plasma STC1 level but an increased frequency of CD4^(+)NKT cells combined to distinguish the latter.Intercorrelation analyses revealed a particular presymptomatic immunotype mainly manifesting as monocytic overactivation and differentiation blockage,a likely lymphocyte exhaustion and immunosuppression,yielding mechanistic insights into SSIS fate determination,which could potentially improve 5ARS-CoV-2 management.Shanhe Yu Caixia Di Shijun Chen Mingquan Guo Jiayang Yan Zhaoqin Zhu Li Liu Ruixue Feng Yinyin Xie Ruihong Zhang Juan Chen Mengxi Wang Dong Wei Hai Fang Tong Yin Jinyan Huang Saijuan Chen Hongzhou Lu Jiang Zhu Jieming Qu 2021Cell Research2021,31,11:4
8Genome editing in plants with MAD7 nuclease显示文摘MAD7 is an engineered nuclease of the Class 2 type V-A CRISPR-Cas(Cas12 a/Cpf1)family with a low level of homology to canonical Cas12 a nucleases.It has been publicly released as a royalty-free nuclease for both academic and commercial use.Here,we demonstrate that the CRISPR-MAD7 system can be used for genome editing and recognizes T-rich PAM sequences(YTTN)in plants.Its editing efficiency in rice and wheat is comparable to that of the widely used CRISPR-Lb Cas12 a system.We develop two variants,MAD7-RR and MAD7-RVR that increase the target range of MAD7,as well as an M-AFID(a MAD7-APOBEC fusion-induced deletion)system that creates predictable deletions from 50-deaminated Cs to the MAD7-cleavage site.Moreover,we show that MAD7 can be used for multiplex gene editing and that it is effective in generating indels when combined with other CRISPR RNA orthologs.Using the CRISPR-MAD7 system,we have obtained regenerated mutant rice and wheat plants with up to 65.6%efficiency.Qiupeng Lin Zixu Zhu Guanwen Liu Chao Sun Dexing Lin Chenxiao Xue Shengnan Li Dandan Zhang Caixia Gao Yanpeng Wang Jin-Long Qiu 2021Journal of Genetics and Genomics2021,48,6:4
9Alloyed Au-Ag nanorods with desired plasmonic properties and stability in harsh environments显示文摘Bio-chemical molecular detection in the nanoscale, based on alloyed nanorods(NRs) with tunable surface plasmon resonance(SPR) properties and high chemical stability, has attracted particular interest. In this work,alloyed Au-Ag NRs with tunable aspect ratios were achieved by annealing Au nanobipyramid-directed Au@Ag core-shell NRs. The core-shell NRs were encapsulated within mesoporous silica outer shells to avoid fusion or aggregation. The structural stability of fully alloyed Au-Ag NRs, including chemical and thermal stability, is remarkably improved compared with that of Au@Ag core-shell NRs. The alloyed NRs would maintain the rod-like structure after being incubated in etchant solution, while Au@Ag core-shell NRs would decay into nanobipyramids.Additionally, fully alloyed NRs present stable morphology under annealing at high temperatures of up to 600℃ in air. Benefiting from excellent structural and chemical stabilities, the surface-enhanced Raman scattering effect based on alloyed NRs is stable in harsh environments. Taking advantage of tunable SPR properties(600–1800 nm) and excellent stability, the obtained nanostructures can serve as drug carriers. The perfect photo-thermal effect induced by the particular SPR of alloyed NRs can improve the release efficiency of drugs.Yuan Ni Caixia Kan Longbing He Xingzhong Zhu Mingming Jiang Daning Shi 2019Photonics Research2019,7,5:3
10β-Elemene-loaded polymeric micelles intensify anti-carcinoma efficacy and alleviate side effects显示文摘β-Elemene is a volatile oil used for the treatment of cancer,but poor solubility,low bioavailability,and various adverse reactions limit its application.For amelio rating risks of the venous toxicity ofβ-elemene,intravenously injectable micelle ofβ-elemene was prepared using the thin-film hydration method.The results pointed out the micelles were uniformly spherical with about 20.96±0.1966 nm in average diameter and exhibited high entrapment efficiency(99.02%±0.88%).As revealed by drug release studies in vitro,β-elemene micelles had sustained drug release.Compared with freeβ-elemene,the micelles increased the drug cellular uptake and enhanced the anti-tumor effect in vitro through retarding cell cycle and inducing apoptosis.Meanwhile,the elevated se rum stability o fβ-elemene micelles implied less drug leakage and reduced toxicity.The wound healing and tube formation assay in vitro demonstrated the anti-metastasis and anti-angiogenesis effects ofβ-elemene micelles.Moreover,the pharmacokinetics study showed the AUC and T1/2 ofβ-elemene in micelle group were 1.79 and 1.62 times of that in free fi-elemene group,suggesting the circulation time ofβ-elemene in the blood had been prolonged.In addition,β-elemene micelles showed a favorable antitumor response compared with theβ-elemene solution on C26 colon cance r-bearing mice model.Local irritation study investigated in rabbits indicated that theβ-elemene micelles strikingly mitigated the irritation to the injection sites compared with freeβ-elemene.These results proved that the micelle could be a good candidate as an auspicious drug delivery system ofβ-elemene for the prospective clinical treatment of carcinoma.Qiaoqiao Hu Lan Bai Zejiang Zhu Zhengying Su Peng Bai Minghai Tang Caixia Dou Junfeng Yan Rongsheng Tong Wuyu Zhang Lijuan Chen Lulu Cai 2020Chinese Chemical Letters2020,31,3:2
11Repeated Failure in Reward Pursuit Alters Innate Drosophila Larval Behaviors显示文摘Animals always seek rewards and the related neural basis has been well studied. However, what happens when animals fail to get a reward is largely unknown,although this is commonly seen in behaviors such as predation. Here, we set up a behavioral model of repeated failure in reward pursuit(RFRP) in Drosophila larvae. In this model, the larvae were repeatedly prevented from reaching attractants such as yeast and butyl acetate, before finally abandoning further attempts. After giving up, they usually showed a decreased locomotor speed and impaired performance in light avoidance and sugar preference,which were named as phenotypes of RFRP states. In larvae that had developed RFRP phenotypes, the octopamine concentration was greatly elevated, while tbh mutants devoid of octopamine were less likely to develop RFRP phenotypes, and octopamine feeding efficiently restored such defects. By down-regulating tbh in different groups of neurons and imaging neuronal activity, neurons that regulated the development of RFRP states and the behavioral exhibition of RFRP phenotypes were mapped to a small subgroup of non-glutamatergic and glutamatergic octopaminergic neurons in the central larval brain. Our results establish a model for investigating the effect of depriving an expected reward in Drosophila and provide a simplified framework for the associated neural basis.Yue Fei Dikai Zhu Yixuan Sun Caixia Gong Shenyang Huang Zhefeng Gong 2018Neuroscience Bulletin2018,34,6:2

13Regioisomerism effect(RIE) on optimizing ultralong organic phosphorescence lifetimes显示文摘Organic phosphorescence materials demonstrate potential optoelectronic applications due to their remarkably ultralong organic phosphorescence(UOP)lifetime and abundant optical characteristics prior to the fluorescence materials.For a better insight into the intrinsic relationship among regioisomeric molecules,crystalline interactions,and phosphorescence properties,three crystalline dicarbazol-9-yl pyrazine-based regioisomers with para-,meta-and ortho-convergent substitutions(p-DCzP,m-DCzP,and o-DCzP)were designed and presented gradually increased UOP lifetimes prolonging from 63.14,127.93 to 350.46 ms,respectively,due to the regioisomerism effect(RIE)which would be an effective strategy for better understanding of structure-property of UOP materials.Yanni Zhang Jianfeng Zhao Caixia Zhu Lifang Bian Huifang Shi Shiming Zhang Huili Ma Wei Huang 2019Chinese Chemical Letters2019,30,11:1

17Low-temperature and high-voltage planar micro-supercapacitors based on anti-freezing hybrid gel electrolyte显示文摘Micro-supercapacitors(MSCs)are considered as highly competitive power sources for miniaturized electronics.However,narrow voltage window and poor anti-freezing properties of MSCs in conventional aqueous electrolytes lead to low energy density and limited environmental adaption.Herein,we report the construction of low-temperature and high-energy-density MSCs based on anti-freezing hybrid gel electrolytes(HGE)through introducing ethylene glycol(EG)additives into aqueous LiCl electrolyte.Since EG partially destroys hydrogen bond network among water molecules,the HGE exhibits maximum electrochemical stability window of 2.7 V and superior anti-freezing features with a glass transition temperature of-62.8℃.Further,the optimized MSCs using activated carbon microelectrodes possess impressive volumetric capacitance of 28.9 F cm^(-3)and energy density of 10.3 mWh cm^(-3)in the voltage of 1.6 V,2.6 times higher than MSCs tested in 1.2 V.Importantly,the MSCs display 68.3%capacitance retention even at-30℃ compared to the value at 25℃,and ultra-long cyclability with 85.7%of initial capacitance after 15,000 times,indicating extraordinary low-temperature performance.Besides,our devices offer favorable flexibility and modular integration.Therefore,this work provides a general strategy of realizing flexible,safe and anti-freezing microscale power sources,holding great potential towards subzero-temperature microelectronic applications.Manning Chen Xiaoyu Shi Xiaolei Wang Hanqing Liu Sen Wang Caixia Meng Yu Liu Liangzhu Zhang Yuanyuan Zhu Zhong-Shuai Wu 2022Journal of Energy Chemistry2022,31,9:1
18Molecular insights of nanozymes from design to catalytic mechanism显示文摘Emerging as cost-effective potential alternatives to natural enzymes,nanozymes have attracted increasing interest in broad fields.To exploit the in-depth potential of nanozymes,rational structural engineering and explicit catalytic mechanisms at the molecular scale are required.Recently,impressive progress has been made in mimicking the characteristics of natural enzymes by constructing metal active sites,binding pockets,scaffolds,and delicate allosteric regulation.Ingenious in-depth studies have been conducted with advances in structural characterization and theoretical calculations,unveiling the“black box”of nanozymecatalytic mechanisms.This review introduces the state-of-art synthesis strategies by learning from the natural enzyme counterparts and summarizes the general overview of the nanozyme mechanism with a particular emphasis on the adsorbed intermediates and descriptors that predict the nanozyme activity.The emerging activity assessment methodology that illustrates the relationship between electrochemical oxygen reduction and enzymatic oxygen reduction is discussed with up-to-date advances.Future opportunities and challenges are presented in the end to spark more profound work and attract more researchers from various backgrounds to the flourishing field of nanozymes.Yuan Xu Zhixin Zhou Nankai Deng Kangchun Fu Caixia Zhu Qing Hong Yanfei Shen Songqin Liu Yuanjian Zhang 2023Science China Chemistry2023,66,5:1
