| 1 | The role of the gut microbiome and its metabolites in metabolic diseases显示文摘It is well known that an unhealthy lifestyle is a major risk factor for metabolic diseases,while in recent years,accumulating evidence has demonstrated that the gut microbiome and its metabolites also play a crucial role in the onset and development of many metabolic diseases,including obesity,type 2 diabetes,nonalcoholic fatty liver disease,cardiovascular disease and so on.Numerous microorganisms dwell in the gastrointestinal tract,which is a key interface for energy acquisition and can metabolize dietary nutrients into many bioactive substances,thus acting as a link between the gut microbiome and its host.The gut microbiome is shaped by host genetics,immune responses and dietary factors.The metabolic and immune potential of the gut microbiome determines its significance in host health and diseases.Therefore,targeting the gut microbiome and relevant metabolic pathways would be effective therapeutic treatments for many metabolic diseases in the near future.This review will summarize information about the role of the gut microbiome in organism metabolism and the relationship between gut microbiome-derived metabolites and the pathogenesis of many metabolic diseases.Furthermore,recent advances in improving metabolic diseases by regulating the gut microbiome will be discussed. | Jiayu Wu Kai Wang Xuemei Wang Yanli Pang Changtao Jiang | 2021 | Protein & Cell2021，12，5： | 40 |
| 2 | Holocene vegetational and climatic variation in westerly-dominated areas of Central Asia inferred from the Sayram Lake in northern Xinjiang,China显示文摘Changes in the vegetation and climate of the westerly-dominated areas in Central Asia during the Holocene were interpreted using pollen-assemblages and charcoal data from a 300-cm-long sediment core of the Sayram Lake,northern Xinjiang.Accele-rator Mass Spectrometry(AMS) radiocarbon dating methods were applied to bulk organic matter of the samples.Artemisia spp./Chenopodiaceae ratios and results from principal component analysis were used to infer that the lake basin was dominated by desert vegetation before ca.9.6 cal.ka BP,which suggests a warm and dry climate in the early Holocene.Desert steppe/steppe expanded during 9.6-5.5 cal.ka BP,indicating a remarkable increase both in the precipitation and temperature during the mid-Holocene.Desert vegetation dominated between 6.5 and 5.5 cal.ka BP,marking an extreme warmer and drier interval.The steppe/meadow steppe recovered,and temperatures decreased from 5.5 cal.ka BP in the late Holocene,as indicated by the increased abundance of Artemisia and the development of meadows.Holocene temperatures and moisture variations in the Sayram Lake areas were similar to those of adjacent areas.This consistency implies that solar radiation was the main driving factor for regional temperature changes,and that the effect of temperature variations was significant on regional changes in humidity.The evolution of climate and environment in the Sayram Lake areas,which were characterized as dry in the early Holocene and relatively humid in the middle-late Holocene,are clearly different from those in monsoonal areas.Dry conditions in the early Holocene in the Sayram Lake areas were closely related to decreased water vapor advection.These conditions were a result of reduced westerly wind speeds and less evaporation upstream,which in turn were caused by seasonal changes in solar radiation superimposed by strong evaporation following warming and drying local climate. | JIANG QingFeng JI JunFeng SHEN Ji Ryo MATSUMOTO TONG GuoBang QIAN Peng REN XueMei YAN DeZhi | 2013 | Science China Earth Sciences2013，56，3： | 32 |
| 3 | Ablation of gut microbiota alleviates obesity-induced hepatic steatosis and glucose intolerance by modulating bile acid metabolism in hamsters显示文摘Since metabolic process differs between humans and mice, studies were performed in hamsters, which are generally considered to be a more appropriate animal model for studies of obesityrelated metabolic disorders. The modulation of gut microbiota, bile acids and the farnesoid X receptor(FXR) axis is correlated with obesity-induced insulin resistance and hepatic steatosis in mice. However,the interactions among the gut microbiota, bile acids and FXR in metabolic disorders remained largely unexplored in hamsters. In the current study, hamsters fed a 60% high-fat diet(HFD) were administeredvehicle or an antibiotic cocktail by gavage twice a week for four weeks. Antibiotic treatment alleviated HFD-induced glucose intolerance, hepatic steatosis and inflammation accompanied with decreased hepatic lipogenesis and elevated thermogenesis in subcutaneous white adipose tissue(sWAT). In the livers of antibiotic-treated hamsters, cytochrome P450 family 7 subfamily B member 1(CYP7 B1) in the alternative bile acid synthesis pathway was upregulated, contributing to a more hydrophilic bile acid profile with increased tauro-β-muricholic acid(TβMCA). The intestinal FXR signaling was suppressed but remained unchanged in the liver. This study is of potential translational significance in determining the role of gut microbiota-mediated bile acid metabolism in modulating diet-induced glucose intolerance and hepatic steatosis in the hamster. | Lulu Sun Yuanyuan Pang Xuemei Wang Qing Wu Huiying Liu Bo Liu George Liu Min Ye Wei Kong Changtao Jiang | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 29 |
| 4 | Effects of dietary Clostridium butyricum supplementation on growth performance,intestinal development,and immune response of weaned piglets challenged with lipopolysaccharide显示文摘Background: Weanling pigs, with immature immune system and physiological function, usually experience postweaning diarrhea. This study determined the effects of dietary Clostridium butyricum supplementation on growth performance, diarrhea, and immunity of weaned pigs challenged with lipopolysaccharide(LPS).Methods: In Experiment(Exp.) 1,144 weaned piglets were weaned at 21 d and randomly assigned to six groups,with six replicates per group and four pigs per replicate, receiving a control diet(CON) or diet supplemented with antibiotics(AB) or C. butyricum(CB)(0.1%, 0.2%, 0.4%, or 0.8%), respectively. All diets in Exp. 1 were a highly digestible basal diet, with 3,000 mg/kg zinc oxide supplied in the first 2 wk only. In Exp. 2, 180 piglets were weaned at 21 d and randomly assigned to five groups, with six replicates per group and six pigs per replicate, receiving CON, AB, or CB(0.2%, 0.4%, or 0.6%) diets. The digestibility of diets was lower than those in Exp. 1, and did not include zinc oxide. At 36 d of Exp. 2, 12 piglets were selected from each of the CON and 0.4% CB groups, six piglets were intraperitoneally injected with LPS(50 μg/kg body weight) and the other six piglets with normal saline;animals were killed at 4 h after injection to collect blood, intestine, and digesta samples for biochemical analysis.Results: In Exp. 1, CB and AB diets had no effect on growth performance of piglets. In Exp. 2, 0.4% CB decreased feed-gain ratio(P < 0.1), diarrhea score(P < 0.05), and increased duodenal, jejunal, and ileal villus height and jejunal villus height/crypt depth(P < 0.05). The 0.4% CB decreased the plasma tumor necrosis factor(TNF) α(P < 0.05) but increased ileal mucosa IL-10 and TLR2 mRNA expression(P < 0.05). Furthermore, 0.4% CB altered the microbial profile, with Bacillus and Ruminococcaceae UGG-003 at genus level and Lactobacillus casei and Parasutterella secunda at species level were higher than CON in colonic content(P < 0.05).Conclusions: Dietary C. butyricum supplementation had positive effects on growth of weaned piglets with less digestible diets. There was a tendency to reduce the feed-gain ratio, which could reduce feed costs in pig production. Moreover, C. butyricum decreased post-weaning diarrhea by improving the intestinal morphology,intestinal microflora profile, and immune function. | Ling Chen Shuang Li Jie Zheng Wentao Li Xuemei Jiang Xilun Zhao Jian Li Lianqiang Che Yan Lin Shengyu Xu Bin Feng Zhengfeng Fang De Wu | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 26 |
| 5 | Recently duplicated sesterterpene(C25) gene clusters in Arabidopsis thaliana modulate root microbiota显示文摘Land plants co-speciate with a diversity of continually expanding plant specialized metabolites(PSMs) and root microbial communities(microbiota).Homeostatic interactions between plants and root microbiota are essential for plant survival in natural environments.A growing appreciation of microbiota for plant health is fuelling rapid advances in genetic mechanisms of controlling microbiota by host plants.PSMs have long been proposed to mediate plant and single microbe interactions.However,the effects of PSMs,especially those evolutionarily new PSMs,on root microbiota at community level remain to be elucidated.Here,we discovered sesterterpenes in Arabidopsis thaliana,produced by recently duplicated prenyltransferase-terpene synthase(PT-TPS) gene clusters,with neo-functionalization.A single-residue substitution played a critical role in the acquisition of sesterterpene synthase(sesterTPS) activity in Brassicaceae plants.Moreover,we found that the absence of two root-specific sesterterpenoids,with similar chemical structure,significantly affected root microbiota assembly in similar patterns.Our results not only demonstrate the sensitivity of plant microbiota to PSMs but also establish a complete framework of host plants to control root microbiota composition through evolutionarily dynamic PSMs. | Qingwen Chen Ting Jiang Yong-Xin Liu Haili Liu Tao Zhao Zhixi Liu Xiangchao Gan Asis Hallab Xuemei Wang Juan He Yihua Ma Fengxia Zhang Tao Jin M.

| 6 | Effects of dietary supplementation with essential oils and protease on growth performance,antioxidation,inflammation and intestinal function of weaned pigs显示文摘This experiment evaluated the impacts of essential oils(EO)and protease(PRO),independently or in combination,on growth performance,antioxidation,inflammation and intestinal function of weaned pigs.One hundred and sixty weaned pigs(21 d of age,BW of 6.74±0.20 kg)were randomly divided into 4 treatments with 8 replicate pens of 5 pigs per pen.Dietary treatments included the following:1)control diet(CON),2)CON with 300 mg/kg essential oils(EO),3)CON with 500 mg/kg protease(PRO),4)CON with 300 mg/kg essential oil and 500 mg/kg protease(EO + PRO).On d 8,one pig from each penwas selected for sampling.The remaining pigs were fed for an additional week and growth performance was monitored during this period.Dietary treatments had no marked effects(P>0.05)on the growth performance of pigs.However,pigs receiving EO diet had higher(P<0.05)serumglutathione peroxidase(GSH-Px)activity,and tended to decrease(P=0.063)serum concentration of tumor necrosis factor-a(TNF-a).In addition,pigs receiving EO diet had higher(P<0.05)abundances of phylum Actinobacteria,and genera Bifidobacterium,and lower(P<0.05)phylum Bacteroidetes and genera Alloprevotella in colonic digesta.Pigs receiving PRO diet decreased(P<0.05)the serum concentration of malondialdehyde(MDA)and diamine oxidase activity,increased(P<0.05)the villus height and the ratio of villus height to crypt depth in duodenum,increased sucrase activity in jejunal mucosa,and also increased the abundance of phylum Actinobacteria in colonic digesta.Furthermore,the synergistic effects of EO and PROwas observed(P<0.05)for pigs with decreasing serum TNF-a concentration and increasing serum GSH-Px activity.Collectively,the results indicated that dietary supplementation of EO and PRO had no significant effects on growth performance of weaned pigs.EO diet appeared to improve antioxidant activity and intestinal microbiota,while PRO diet improved intestinal morphology and digestive enzyme activity,and there was a synergistic effect of EO and PRO on reducing inflammatory parameters in weaned pigs. | Xie Peng Qiang Zhou Cheng Wu Jian Zhao Quan Tan Ying He Liang Hu Zhengfeng Fang Yan Lin Shengyu Xu Bin Feng Jian Li Yong Zhuo Chris Van Ginneken Xuemei Jiang De Wu Lianqiang Che | 2022 | Animal Nutrition2022，，2： | 8 |
| 7 | Rumen microbiome structure and metabolites activity in dairy cows with clinical and subclinical mastitis显示文摘Background:Due to the high prevalence and complex etiology,bovine mastitis(BM)is one of the most important diseases to compromise dairy cow health and milk quality.The shift in milk compositions has been widely investigated during mastitis,but recent studies suggested that gastrointestinal microorganism also has a crucial effect on the inflammation of other peripheral tissues and organs,including the mammary gland.However,research focused on the variation of rumen inner-environment during mastitis is still limited.Therefore,the ruminal microbial profiles,metabolites,and milk compositions in cows with different udder health conditions were compared in the present study.Furthermore,the correlations between udder health status and ruminal conditions were investigated.Based on the somatic cell counts(SCC),California mastitis test(CMT)parameters and clinical symptoms of mastitis,60 lactating Holstein dairy cows with similar body conditions(excepted for the udder health condition)were randomly divided into 3 groups(n=20 per group)including the healthy(H)group,the subclinical mastitis(SM)group and the clinical mastitis(CM)group.Lactation performance and rumen fermentation parameters were recorded.And rumen microbiota and metabolites were also analyzed via 16S rRNA amplicon sequencing and untargeted metabolomics,respectively.Results:As the degree of mastitis increased,rumen lactic acid(LA)(P<0.01),acetate,propionate,butyrate,valerate(P<0.001),and total volatile fatty acids(TVFAs)(P<0.01)concentrations were significantly decreased.In the rumen of CM cows,the significantly increased bacteria related to intestinal and oral inflammation,such as Lachnospiraceae(FDR-adjusted P=0.039),Moraxella(FDR-adjusted P=0.011)and Neisseriaceae(FDR-adjusted P=0.036),etc.,were accompanied by a significant increase in 12-oxo-20-dihydroxy-leukotriene B4(FDR-adjusted P=5.97×10^(−9))and 10beta-hydroxy-6beta-isobutyrylfuranoeremophilane(FDR-adjusted P=3.88×10^(−10)).Meanwhile,in the rumen of SM cows,the Ruminiclostridium_9(FDR-adjusted P=0.042)and Enterorhabdus(FDR-adjusted P=0.043)were increased along with increasing methenamine(FDR-adjusted P=6.95×10^(−6)),5-hydroxymethyl-2-furancarboxaldehyde(5-HMF)(FDR-adjusted P=2.02×10^(−6))and 6-methoxymellein(FDR-adjusted P=2.57×10^(−5)).The short-chain fatty acids(SCFAs)-producing bacteria and probiotics in rumen,including Prevoterotoella_1(FDRadjusted P=0.045)and Bifidobacterium(FDR-adjusted P=0.035),etc.,were significantly reduced,with decreasing 2-phenylbutyric acid(2-PBA)(FDR-adjusted P=4.37×10^(−6)).Conclusion:The results indicated that there was a significant shift in the ruminal microflora and metabolites associated with inflammation and immune responses during CM.Moreover,in the rumen of cows affected by SM,the relative abundance of several opportunistic pathogens and the level of metabolites which could produce antibacterial compounds or had a competitive inhibitory effect were all increased. | Yue Wang Xuemei Nan Yiguang Zhao Linshu Jiang Mengling Wang Hui Wang Fan Zhang Fuguang Xue Dengke Hua Jun Liu Junhu Yao Benhai Xiong | 2021 | Journal of Animal Science and Biotechnology2021，12，3： | 6 |
| 8 | The cellular labeling and pH-sensitive responsive-drug release of celastrol in cancer cells based on Cys-CdTe QDs显示文摘As one of the active compounds derived from Traditional Chinese Medicine,Celastrol(CSL)had cytotoxicity for human leukemia cancer cells K562 and its multidrug-resistant cell line K562/A02.Here,we introduced cysteamine-modified CdTe QDs as the labeling and drug carrier into CSL research and found that the self-assembly and conjugation of anticancer molecular CSL with the Cys-CdTe QDs could significantly increase the drug’s cytotoxicity for K562 cells.More important,these CSL-Cys-CdTe nanocomposites could overcome the multidrug resistance of K562/A02 cells and efficiently inhibit the cancer cell proliferation by realizing the pH-sensitive responsive release of CSL to cancer cells.The enhanced cytotoxicity was caused by the increase of the G2/M phase arrest for K562/A02 cells as well as for K562 cells.Cys-CdTe QDs can readily bind on the cell plasma membranes and be internalized into cancer cells to trace and detect human leukemia cancer cells in real time.In addition,these Cys-CdTe QDs can facilitate the inhibition of the multidrug resistance of K562/A02 cells and readily induce apoptosis.As a good photosensitizer for the therapy,labeling,and tracing of cancer cells,the combination of CSL with Cys-CdTe QDs can optimize the use of and a new potential therapy method for CSL and yield new tools to explore the mechanisms of active compounds from Traditional Chinese Medicine. | LI JingYuan SHI LiXin SHAO YiXiang SELKE Matthias CHEN BaoAn JIANG Hui WANG XueMei | 2014 | Science China Chemistry2014，57，6： | 6 |
| 9 | Structural changes in the gray matter of unmedicated patients with obsessive-compulsive disorder: a voxel-based morphometric study显示文摘The aim of the current study was to use whole brain voxel-based morphometry(VBM)to assess the gray matter(GM)changes in unmedicated patients with obsessive-compulsive disorder(OCD)compared with normal controls.We compared the GM volumes in28 patients with 22 matched healthy controls using a1.5T MRI.Three-dimensional T1-weighted magnetic resonance images were obtained from all participants.VBM was performed to detect GM volume differences between the two groups.We detected increased regional GM volumes in the bilateral middle temporal gyri,bilateral middle occipital gyri,bilateral globus pallidus,right inferior parietal gyrus,left superior parietal gyrus,right parahippocampus,right supramarginal gyrus,right medial superior frontal gyrus,and left inferior frontal opercular cortex in the OCD patients relative to controls(P<0.001,uncorrected,cluster size>100 voxels).No decreased GM volume was found in the OCD group compared with normal controls.Our findings suggest that structural changes in the GM are not limited to fronto-striato-thalamic circuits in the pathogenesis of OCD.Temporo-parietal cortex may also play an important role. | Ling Tan Qing Fan Chao You Jijun Wang Zhao Dong Xuemei Wang Kemin Chen Zeping Xiao Kaida Jiang | 2013 | Neuroscience Bulletin2013，29，5： | 5 |
| 10 | Bivalent Metal Ions Tethered Fluorescent Gold Nanoparticles as a Reusable Peroxidase Mimic Nanozyme显示文摘Nanozymes are a class of mimic enzymes that have both unique properties of nanomaterials and catalytic functions.They are widely used in medicine,food,agriculture,and environment due to their high catalytic efficiency,stability,economy,and large-scale preparation.In this work,a simple,gentle method was applied to synthesize adenosine phosphates(AXP)templated gold nanoparticles(Au NPs)with small size,good optical properties,and peroxidase-like activities.In the presence of hydrogen peroxide(H_(2)O_(2)),the peroxidase substrate 3,3′,5,5′-tetramethylbenzidine(TMB)could be oxidized to form blue-colored oxidized TMB(oxTMB),which demonstrates that the AuAXP NPs have peroxidase-like activities.Inter-estingly,the introduction of bivalent metal ions into AuAXP NPs allows their reusability.Among them,after three rounds of recycling,the catalytic activity of Mg@AuAMP could still reach 92.69%compared to the original level,which showed excellent reusability.In addition,the glutathione(GSH)detection was realized with a linear detection range of 0-200μM due to the GSH-induced loss of peroxidase-like activities.Overall,this work provides a new idea of recycling for biosensor and catalytic analysis. | Liu Liu Hui Jiang Xuemei Wang | 2019 | Journal of Analysis and Testing2019，3，3： | 4 |
| 11 | Fast-Suppressor Screening for New Components in Protein Trafficking,Organelle Biogenesis and Silencing Pathway in Arabidopsis thaliana Using DEX-Inducible FREE1-RNAi Plants显示文摘Membrane trafficking is essential for plant growth and responses to external signals.The plant unique FYVE domain-containing protein FREE1 is a component of the ESCRT complex(endosomal sorting complex required for transport).FREE1 plays multiple roles in regulating protein trafficking and organelle biogenesis including the formation of intraluminal vesicles of multivesicular body(MVB),vacuolar protein transport and vacuole biogenesis,and autophagic degradation.FREE1 knockout plants show defective MVB formation,abnormal vacuolar transport,fragmented vacuoles,accumulated autophagosomes,and seedling lethality.To further uncover the underlying mechanisms of FREE1 function in plants,we performed a forward genetic screen for mutants that suppressed the seedling lethal phenotype of FREE1-RNAi transgenic plants.The obtained mutants are termed as suppressors of free1(sof).To date,229 putative sof mutants have been identified.Barely detecting of FREE1 protein with M3plants further identified 84 FREE1-related suppressors.Also145 mutants showing no reduction of FREE1 protein were termed as RNAi-related mutants.Through next-generation sequencing(NGS)of bulked DNA from F2mapping population of two RNAi-related sof mutants,FREE1-RNAi T-DNA inserted on chromosome 1 was identified and the causal mutation of putative sof mutant is being identified similarly.These FREE1-and RNAi-related sof mutants will be useful tools and resources for illustrating the underlying mechanisms of FREE1 function in intracellular trafficking and organelle biogenesis,as well as for uncovering the new components involved in the regulation of silencing pathways in plants. | Qiong Zhao Caiji Gao PoShing Lee Lin Liu Shaofang Li Tangjin Hu Jinbo Shen Shuying Pan Hao Ye Yunru Chen Wenhan Cao Yong Cui Peng Zeng Sheng Yu Yangbin Gao Liang Chen Beixin Mo Xin Liu Shi Xiao Yunde Zhao Silin Zhong Xuemei Chen Liwen Jiang | 2015 | Journal of Genetics and Genomics2015，42，6： | 4 |

| 13 | Relationships between tree-ring cell features of Pinus koraiensis and climate factors in the Changbai Mountains,Northeastern China显示文摘Anatomical characteristics have been proven useful for extracting climatic signals. To examine the climatic signals recorded by tree-ring cell features in the Changbai Mountains, we measured cell number and cell lumen diameter, in addition to ring widths, of Korean pine(Pinus koraiensis) tree rings at sites of varied elevation,and we developed chronologies of cell number(CN), mean lumen diameter(MLD), maximum lumen diameter(MAXLD) and tree-ring width(TRW). The chronologies were correlated with climatic factors monthly mean temperature and the sum of precipitation. As shown by our analysis, the cell parameter chronologies were suitable for dendroclimatology studies. CN and TRW shared relatively similar climatic signals which differed from MLD andMAXLD, and growth-climate relationships were elevationdependent, as shown by the following findings:(1) at each elevation, MLD and MAXLD recorded different monthly climatic signals from those recorded by TRW for the same climatic factors; and(2) MLD and MAXLD recorded climatic factors that were absent from TRW at lower and middle elevations. Cell lumen diameter proved to be an effective archive for improving the climate reconstruction for this study area. | Hui Wang Xuemei Shao Xiuqi Fang Yuan Jiang Chunlan Liu Qing Qiao | 2017 | Journal of Forestry Research2017，28，1： | 3 |
| 14 | Construction and analysis of a plant transformation binary vector pBDGG harboring a bi-directional promoter fusing dual visible reporter genes显示文摘The constitutive promoter of cauliflower mosaic virus 35S (CaMV 35S) is a polar unidirectional promoter and is widely used in plant genetic engineering. In the present study, the unidirectional CaMV 35S promoter has been modified to a bi-directional promoter by fusing its minimal promoter element to the 5′end of CaMV 35S promoter in the opposite orientation. To qualitatively and quantitatively esti-mate its bi-directional transcriptional function and activity, two visible reporter genes, gusA (β-glucuronidase, GUS) and gfp (green fluo-rescent protein, GFP), were fused to the two ends of the promoter in bi-orientations ending with NOS terminator sequences, respectively. Stable expression of gusA and gfp genes in transgenic tobacco (Nicotiana tabacum L.) was visulized by histochemically staining for GUS and fluorescence microscopic observation under UV for GFP in transgenic plants. The expression of two reporter genes showed that the constructed bi-directional promoter did have the bi-directional transcriptional function in both expected orientations. The quantitative estimation of GUS and GFP were determined on a HITACHI F1000 Fluorescence Spectrophotometer with various wavelengths of excita-tion and emission. The GUS activity varied from 8 to 250 pmol 4-MU / min / mg protein and the GFP content varied from 0.9 to 1.8 μg / mg protein in various lines of transgenic tobacco plants. Higher GUS activity generally coupled with lower GFP content, and vice versa. | Chunxiao Zhang Ying Gai Wenqi Wang Yanyan Zhu Xuemei Chen Xiangning Jiang | 2008 | Journal of Genetics and Genomics2008，35，4： | 3 |
| 15 | In vivo rapid fluorescence imaging of Alzheimer's disease through accurate target bio-marking of zinc gluconate显示文摘Alzheimer's disease(AD) is a progressive and age-related irreversible neurodegenerative disease. When AD occurs, the relevant amount of zinc ions in brain considerably changes. In this contribution, we have explored the possibility of in vivo rapid fluorescence imaging of AD through accurate targeting biomarker of zinc gluconate. By using the 3- and 6-month-old Alzheimer's model mice(AD-1) as the experimental models, our observations demonstrate that zinc gluconate molecules could pass through the blood–brain barrier and then produce hippocampus region-specific accumulation of fluorescent zinc nanoclusters in vivo, thus allowing kinetically controlled selective imaging of AD by fluorescence bioimaging. | Lanmei Lai Chunqiu Zhao Meina Su Jing Ye Hui Jiang Xuemei Wang | 2015 | Science Bulletin2015，60，16： | 3 |

| 17 | Evaluating the Role of International Trade in the Growth of China's CO_2 Emissions显示文摘International trade matters in assessing the extent of China’s responsibility for CO2 emissions.A determining factor is whether emissions are measured in production or in consumption terms.Based on a series of input-output tables,an empirical analysis is conducted to measure the impact of international trade on China’s emissions growth during the period 1997 to 2007.The authors also measure the impact on emissions of bilateral trade between China and US,European Union and Japan.As the largest of the developing countries,China has a trade surplus that can substantially influence its measured responsibility for emissions.The authors consider some policy implications for international negotiations to reduce global greenhouse gas emissions. | JIANG Xuemei LIU Yifang ZHANG Jin ZU Lei WANG Shouyang GREEN Christopher | 2015 | Journal of Systems Science & Complexity2015，28，4： | 3 |
| 18 | Evolutionary transition between invertebrates and vertebrates via methylation reprogramming in embryogenesis显示文摘Major evolutionary transitions are enigmas,and the most notable enigma is between invertebrates and vertebrates,with numerous spectacular innovations.To search for the molecular connections involved,we asked whether global epigenetic changes may offer a clue by surveying the inheritance and reprogramming of parental DNA methylation across metazoans.We focused on gametes and early embryos,where the methylomes are known to evolve divergently between fish and mammals.Here,we find that methylome reprogramming during embryogenesis occurs neither in pre-bilaterians such as cnidarians nor in protostomes such as insects,but clearly presents in deuterostomes such as echinoderms and invertebrate chordates,and then becomes more evident in vertebrates.Functional association analysis suggests that DNA methylation reprogramming is associated with development,reproduction and adaptive immunity for vertebrates,but not for invertebrates.Interestingly,the single HOX cluster of invertebrates maintains unmethylated status in all stages examined.In contrast,the multiple HOX clusters show dramatic dynamics of DNA methylation during vertebrate embryogenesis.Notably,the methylation dynamics of HOX clusters are associated with their spatiotemporal expression in mammals.Our study reveals that DNA methylation reprogramming has evolved dramatically during animal evolution,especially after the evolutionary transitions from invertebrates to vertebrates,and then to mammals. | Xiaocui Xu Guoqiang Li Congru Li Jing Zhang Qiang Wang David KSimmons Xuepeng Chen Naveen Wijesena Wei Zhu Zhanyang Wang Zhenhua Wang Bao Ju Weimin Ci Xuemei Lu Daqi Yu Qian-fei Wang Neelakanteswar Aluru Paola Oliveri Yong EZhang Mark QMartindale Jiang Liu | 2019 | National Science Review2019，6，5： | 2 |

| 20 | Recent Progress in Atmospheric Chemistry Research in China: Establishing a Theoretical Framework for the “Air Pollution Complex”显示文摘Atmospheric chemistry research has been growing rapidly in China in the last 25 years since the concept of the“air pollution complex”was first proposed by Professor Xiaoyan TANG in 1997.For papers published in 2021 on air pollution(only papers included in the Web of Science Core Collection database were considered),more than 24000 papers were authored or co-authored by scientists working in China.In this paper,we review a limited number of representative and significant studies on atmospheric chemistry in China in the last few years,including studies on(1)sources and emission inventories,(2)atmospheric chemical processes,(3)interactions of air pollution with meteorology,weather and climate,(4)interactions between the biosphere and atmosphere,and(5)data assimilation.The intention was not to provide a complete review of all progress made in the last few years,but rather to serve as a starting point for learning more about atmospheric chemistry research in China.The advances reviewed in this paper have enabled a theoretical framework for the air pollution complex to be established,provided robust scientific support to highly successful air pollution control policies in China,and created great opportunities in education,training,and career development for many graduate students and young scientists.This paper further highlights that developing and low-income countries that are heavily affected by air pollution can benefit from these research advances,whilst at the same time acknowledging that many challenges and opportunities still remain in atmospheric chemistry research in China,to hopefully be addressed over the next few decades. | Tong ZHU Mingjin TANG Meng GAO Xinhui BI Junji CAO Huizheng CHE Jianmin CHEN Aijun DING Pingqing FU Jian GAO Yang GAO Maofa GE Xinlei GE Zhiwei HAN Hong HE Ru-Jin HUANG Xin HUANG Hong LIAO Cheng LIU Huan LIU Jianguo LIU Shaw Chen LIU Keding LU Qingxin MA Wei NIE Min SHAO Yu SONG Yele SUN Xiao TANG Tao WANG Tijian WANG Weigang WANG Xuemei WANG Zifa WANG Yan YIN Qiang ZHANG Weijun ZHANG Yanlin ZHANG Yunhong ZHANG Yu ZHAO Mei ZHENG Bin ZHU Jiang ZHU | 2023 | Advances in Atmospheric Sciences2023，40，8： | 2 |
