| 1 | Comparative study of the net exchange of CO_(2) in 3 types of vegetation ecosystems on the Qinghai-Tibetan Plateau显示文摘Using the eddy covariance method,from 1 July2003 to 30 June 2004, we conducted the observation andanalysis of ecosystem CO2 flux in 3 types of alpine meadowvegetation (Kobresia humilis, Potentilla fruticosa shrub andKobresia tibetica swamp meadows) on the Qinghai-TibetanPlateau. The results show that the Kobresia humilis meadow,the shrub meadow and the swamp meadow’s highest CO2uptake rates are 16.78, 10.42 and 16.57 μmol·m?2·s?1respectively, while their highest CO2 release rates are 8.22,7.73 and 18.67 μmol·m?2·s?1 respectively. The Kobresiahumilis meadow and shrub meadow’s annual atmosphericuptakes are 282 g CO2/m2 and 53 g CO2/m2, respectively,while swamp meadow’s annual atmospheric release is 478 gCO2/m2. This proves that the Kobresia humilis meadow andthe shrub meadow on the Qinghai-Tibetan Plateau haverelatively low potential for CO2 uptake and release comparedto C4 grasslands, a number of lowland grasslands, andforests. Moreover, swamp meadow has relatively high releasepotential. This, in turn, reveals clear differences in carbonsource/sink between different types of vegetation in theQinghai-Tibetan Plateau alpine meadow ecosystem. Thesedifferences are mainly brought by differences in thevegetations’ photosynthetic capacity and soil respiration. | ZHAO Liang LI Yingnian ZHAO Xinquan XU Shixiao TANG Yanhong YU Guirui GU Song DU Mingyuan WANG Qinxue | 2005 | Chinese Science Bulletin2005,50,16: | 34 |
| 2 | Neutrophil extracellular traps mediate the crosstalk between glioma progression and the tumor microenvironment via the HMGB1/RAGE/IL-8 axis显示文摘Objective:Neutrophil extracellular traps(NETs)produced by tumor-infiltrating neutrophils(TINs)are associated with poor prognosis in patients with several types of cancer.However,the mechanisms underlying the involvement of NETs in glioma progression remain largely unknown.This study aimed to elucidate the roles of NETs in biological processes that drive the crosstalk between glioma progression and the tumor microenvironment.Methods:Neutrophil infiltration and NETs formation were investigated in glioma tissue through immunohistochemistry,and their relationships with clinicopathological features and outcomes were statistically evaluated.The effects of NETs on glioma cell progression were studied in a co-culture system.In vivo and in vitro experiments validated the reactive oxygen species activity and cytokine production of TINs,as well as the ERK signaling pathway activation and the metastasis of gliomas.Results:Neutrophil infiltration and NETs formation were induced in high-grade glioma compared with low-grade glioma.NETs induced by TINs were determined to be an oncogenic marker of high-grade gliomas and to be involved in cell proliferation and invasion.NETs overproduction promoted glioma cell proliferation,migration,and invasion.Furthermore,HMGB1 was found to bind to RAGE and activate the NF-κB signaling pathway in vitro.In addition,NETs stimulated the NF-κB signaling pathway,thus promoting IL-8 secretion in glioblastoma.Subsequently,IL-8 recruited neutrophils which in turn mediated NETs formation via the PI3 K/AKT/ROS axis in TINs.Conclusions:Our results suggest that NETs produced by TINs mediate the crosstalk between glioma progression and the tumor microenvironment by regulating the HMGB1/RAGE/IL-8 axis.Targeting NETs formation or IL-8 secretion may be an effective approach to inhibit glioma progression. | Caijun Zha Xiangqi Meng Lulu Li Shan Mi Da Qian Ziwei Li Pengfei Wu Shaoshan Hu Shihong Zhao Jinquan Cai Yanhong Liu | 2020 | Cancer Biology & Medicine2020,17,1: | 19 |
| 3 | Whole-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 | 2020 | Cell Research2020,30,10: | 19 |
| 4 | SHP2 inhibition triggers anti-tumor immunity and synergizes with PD-1 blockade显示文摘Tyrosine phosphatase SHP2 is a promising drug target in cancer immunotherapy due to its bidirectional role in both tumor growth promotion and T-cell inactivation. Its allosteric inhibitor SHP099 is known to inhibit cancer cell growth both in vitro and in vivo. However, whether SHP099-mediated SHP2 inhibition retards tumor growth in vivo via anti-tumor immunity remains elusive. To address this, a CT-26 colon cancer xenograft model was established in mice since this cell line is insensitive to SHP099.Consequently, SHP099 minimally affected CT-26 tumor growth in immuno-deficient nude mice, but significantly decreased the tumor burden in CT-26 tumor-bearing mice with intact immune system.SHP099 augmented anti-tumor immunity, as shown by the elevated proportion of CD8tIFN-γtT cells and the upregulation of cytotoxic T-cell related genes including Granzyme B andPerforin, which decreased the tumor load. In addition, tumor growth in mice with SHP2-deficient T-cells was markedly slowed down because of enhanced anti-tumor responses. Finally, the combination of SHP099 and antiPD-1 antibody showed a higher therapeutic efficacy than either monotherapy in controlling tumor growthin two colon cancer xenograft models, indicating that these agents complement each other. Our study suggests that SHP2 inhibitor SHP099 is a promising candidate drug for cancer immunotherapy. | Mingxia Zhao Wenjie Guo Yuanyuan Wu Chenxi Yang Liang Zhong Guoliang Deng Yuyu Zhu Wen Liu Yanhong Gu Yin Lu Lingdong Kong Xiangbao Meng Qiang Xu Yang Sun | 2019 | Acta Pharmaceutica Sinica B2019,9,2: | 18 |

| 7 | Metamorphism of the northern Liaoning Complex:Implications for the tectonic evolution of Neoarchean basement of the Eastern Block,North China Craton显示文摘As one of the areas where typical late Archean crust is exposed in the Eastern Block of the North China Craton,the northern Laioning Complex consists principally of tonalitic-trondhjemitic-granodioritic(TTG) gneisses,massive granitoids and supracrustal rocks.The supracrustal rocks,named the Qingyuan Group, consist of interbedded amphibolite,hornblende granulite,biotite granulite and B1F.Petrological evidence indicates that the amphibolites experienced the early prograde(M1),peak(M2) and post-peak(M3) metamorphism.The early prograde assemblage(M1) is preserved as mineral inclusions,represented by actinotite + hornblende + plagioclase + epidote + quartz + sphene,within garnet porphyroblasts.The peak assemblage(M2) is indicated by garnet + clinopyroxene + hornblende + plagioclase + quartz + ilmenite, which occur as major mineral phases in the rock.The post-peak assemblage(M3) is characterized by the garnet + quartz symplectite.The P—T pseudosections in the NCFMASHTO system constructed by using THERMOCALC define the P-T conditions of Ml,M2 and M3 at 490-550℃/<4.5 kbar,780-810℃/7.65- 8.40 kbar and 630-670℃/8.15-9.40 kbar,respectively.As a result,an anticlockwise P-T path involving isobaric cooling is inferred for the metamorphic evolution of the amphibolites.Such a P-T path suggests that the late Archean metamorphism of the northern Liaoning Complex was related to the intrusion and underplating of mantle-derived magmas.The underplating of voluminous mantle-derived magmas leading to metamorphism with an anticlockwise P-T path involving isobaric cooling may have occurred in continental magmatic arc regions,above hot spots driven by mantle plumes,or in continental rift environments. A mantle plume model is favored because this model can reasonably interpret many other geological features of late Archean basement rocks from the northern Liaoning Complex in the Eastern Block of the North China Craton as well as their anticlockwise P—T paths involving isobaric cooling. | Kam Kuen Wu Guochun Zhao Min Sun Changqing Yin Yanhong He Pui Yuk Tam | 2013 | Geoscience Frontiers2013,4,3: | 14 |

| 9 | Foreword to the special issue:looking into the impacts of global warming from the roof of the world显示文摘To most people,the Qinghai-Tibetan Plateau is a place full of mystery.It is also mysterious to many ecologists.The vast central Asian plateau lies at an average elevation>4000 m and covers about 370 million km2.Spanning the highest range of elevations of any ecosystem in the world makes the plateau unique even among alpine ecosystems due to the presence of extreme abiotic environments:the lowest atmospheric pressure and thus,the lowest partial pressures of CO_(2) and O_(2),low temperatures and high levels of radiation,including high ultraviolet radiation. | Yanhong Tang Shiqiang Wan Jinsheng He Xinquan Zhao | 2009 | Journal of Plant Ecology2009,2,4: | 11 |
| 10 | Multi-Stage Hydrocarbon Accumulation and Formation Pressure Evolution in Sinian Dengying FormationCambrian Longwangmiao Formation, Gaoshiti-Moxi Structure, Sichuan Basin显示文摘Sichuan Basin is a typical superimposed basin, which experienced multi-phase tectonic movements, meanwhile Sinian–Cambrian underwent complex hydrocarbon accumulation processes, causing exploration difficulties in the past 60 years. Based on the microscopic evidence of fluid inclusions, combined with basin-modelling, this paper determines stages and time of hydrocarbon accumulation, reconstructs evolution of formation pressure and dynamic processes of hydrocarbon accumulation in Sinian Dengying Formation-Cambrian Longwangmiao Formation of Gaoshiti-Moxi structure. Three stages of inclusions are detected, including a stage of yellow-yellowgreen fluorescent oil inclusions, a stage of blue fluorescent oil-gas inclusions and a stage of non-fluorescent gas inclusions, reflecting the study area has experienced a series of complex hydrocarbon accumulation processes, such as formation of paleo-oil reservoirs, cracking of crude oil, formation of paleo-gas reservoirs and adjustment to present gas reservoirs, which occurred during 219–188, 192–146 and 168–0 Ma respectively. During the period of crude oil cracking, Dengying Formation-Longwangmiao Formation showed weak overpressure to overpressure characteristics, then after adjustment of paleo-gas reservoirs to present gas reservoirs, the pressure in Dengying Formation changed into overpressure but finally reduced to normal pressure system. However, due to excellent preservation conditions, the overpressure strength in Longwangmiao Formation only slightly decreased and was still kept to this day. | Juan Wu Shugen Liu Guozhi Wang Yihua Zhao Wei Sun Jinming Song Yanhong Tian | 2016 | Journal of Earth Science2016,27,5: | 8 |
| 11 | Expert consensus on dental caries management显示文摘Dental Caries is a kind of chronic oral disease that greatly threaten human being’s health.Though dentists and researchers struggled for decades to combat this oral disease,the incidence and prevalence of dental caries remain quite high.Therefore,improving the disease management is a key issue for the whole population and life cycle management of dental caries.So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification.Dentists should perform oral examination and establish dental records at each visit.When treatment plan is made on the base of caries risk assessment and carious lesion activity,we need to work out patient-centered and personalized treatment planning to regain oral microecological balance,to control caries progression and to restore the structure and function of the carious teeth.And the follow-up visits are made based on personalized caries management.This expert consensus mainly discusses caries risk assessment,caries treatment difficulty assessment and dental caries treatment plan,which are the most important parts of caries management in the whole life cycle. | Lei Cheng Lu Zhang Lin Yue Junqi Ling Mingwen Fan Deqin Yang Zhengwei Huang Yumei Niu Jianguo Liu Jin Zhao Yanhong Li Bin Guo Zhi Chen Xuedong Zhou | 2022 | International Journal of Oral Science2022,14,2: | 8 |
| 12 | Mycorrhizal fungal community composition in seven orchid species inhabiting Song Mountain, Beijing, China显示文摘Mycorrhizal fungi play an important role in the germination and growth of orchids essentially influencing their survival,abundance, and spatial distribution. In this study, we investigated the composition of the mycorrhizal fungal community in seven terrestrial orchid species inhabiting Song Mountain, Beijing, China, using Illumina MiSeq high-throughput sequencing. The mycorrhizal communities in the seven orchids were mainly composed of members of the Ceratobasidiaceae, Sebacinales, and Tulasnellaceae, while a number of ectomycorrhizal fungi belonging to the Russulaceae, Tricholomataceae, Thelephoraceae, and Cortinariaceae were occasionally observed. However, the dominant fungal associates and mycorrhizal community differed significantly among the orchid species as well as subhabitats. These findings confirm the previous observation that sympatric orchid species show different preferences for mycorrhizal fungi, which may drive niche partitioning and contribute to their cooccurrence. | Yanhong Chen Yue Gao Linli Song Zeyu Zhao Shunxing Guo Xiaoke Xing | 2019 | Science China(Life Sciences)2019,62,6: | 6 |
| 13 | Doping bioactive elements into a collagen scaffold based on synchronous self-assembly/mineralization for bone tissue engineering显示文摘Pure collagen is biocompatible but lacks inherent osteoinductive,osteoimmunomodulatory and antibacterial activities.To obtain collagen with these characteristics,we developed a novel methodology of doping bioactive elements into collagen through the synchronous self-assembly/mineralization(SSM)of collagen.In the SSM model,amorphous mineral nanoparticles(AMN)(amorphous SrCO3,amorphous Ag3PO4,etc.)stabilized by the polyampholyte,carboxymethyl chitosan(CMC),and collagen molecules were the primary components under acidic conditions.As the pH gradually increased,intrafibrillar mineralization occurred via the self-adaptive interaction between the AMNs and the collagen microfibrils,which were self-assembling;the AMNs wrapped around the microfibrils became situated in the gap zones of collagen and finally transformed into crystals.Srdoped collagen scaffolds(Sr-CS)promoted in vitro cell proliferation and osteogenic differentiation of rat bone marrow mesenchymal stromal cells(rBMSCs)and synergistically improved osteogenesis of rBMSCs by altering the macrophage response.Ag-doped collagen scaffolds(Ag-CS)exhibited in vitro antibacterial effects on S.aureus,as well as cell/tissue compatibility.Moreover,Sr-CS implanted into the calvarial defect of a rat resulted in improved bone regeneration.Therefore,the SSM model is a de novo synthetic strategy for doping bioactive elements into collagen,and can be used to fabricate multifunctional collagen scaffolds to meet the clinical challenges of encouraging osteogenesis,boosting the immune response and fighting severe infection in bone defects. | Huanhuan Liu Mingli Lin Xue Liu Ye Zhang Yuyu Luo Yanyun Pang Haitao Chen Dongwang Zhu Xue Zhong Shiqing Ma Yanhong Zhao Qiang Yang Xu Zhang | 2020 | Bioactive Materials2020,5,4: | 6 |
| 14 | Leaf photosynthesis and simulated carbon budget of Gentiana straminea from a decade-long warming experiment显示文摘Aims Alpine ecosystems may experience larger temperature increases due to global warming as compared with lowland ecosystems.Information on physiological adjustment of alpine plants to temperature changes can provide insights into our understanding how these plants are responding to current and future warming.We tested the hypothesis that alpine plants would exhibit acclimation in photosynthesis and respiration under long-term elevated temperature,and the acclimation may relatively increase leaf carbon gain under warming conditions.Methods Open-top chambers(OTCs)were set up for a period of 11 years to artificially increase the temperature in an alpine meadow ecosystem.We measured leaf photosynthesis and dark respiration under different light,temperature and ambient CO_(2)concentrations for Gentiana straminea,a species widely distributed on the Tibetan Plateau.Maximum rates of the photosynthetic electron transport(J_(max)),RuBP carboxylation(V_(cmax))and temperature sensitivity of respiration Q10 were obtained from the measurements.We further estimated the leaf carbon budget of G.straminea using the physiological parameters and environmental variables obtained in the study.Important findings 1)The OTCs consistently elevated the daily mean air temperature by;1.6℃and soil temperature by;0.5℃during the growing season.2)Despite the small difference in the temperature environment,there was strong tendency in the temperature acclimation of photosynthesis.The estimated temperature optimum of light-saturated photosynthetic CO_(2)uptake(A_(max))shifted;1℃higher from the plants under the ambient regime to those under the OTCs warming regime,and the Amax was significantly lower in the warming-acclimated leaves than the leaves outside the OTCs.3)Temperature acclimation of respiration was large and significant:the dark respiration rates of leaves developed in the warming regime were significantly lower than leaves from the ambient environments.4)The simulated net leaf carbon gain was significantly lower in the in situ leaves under the OTCs warming regime than under the ambient open regime.However,in comparison with the assumed non-acclimation leaves,the in situ warmingacclimated leaves exhibited significantly higher net leaf carbon gain.5)The results suggest that there was a strong and significant temperature acclimation in physiology of G.straminea in response to long-term warming,and the physiological acclimation can reduce the decrease of leaf carbon gain,i.e.increase relatively leaf carbon gain under the warming condition in the alpine species. | Haihua Shen Julia AKlein Xinquan Zhao Yanhong Tang | 2009 | Journal of Plant Ecology2009,2,4: | 5 |
| 15 | Development of a disease-specific health-related quality of life questionnaire for patients with post-stroke spasticity显示文摘OBJECTIVE:This study was designed to develop a disease-specific health-related quality of life(HR-QOL) measure for patients with post-stroke spasticity.METHODS:Based on responses from 20 patients with post-stroke spasticity and an extensive literature search,items potentially used to measure these patients' recovery status were identified and the Apoplexy Spastic-Paralysis Questionnaire(ASPQ) was formed.A sample of 106 patients was then tested twice using the ASPQ,the Self-rating Depression Scale(SDS) and the Stroke-specific Quality of Life(SS-QOL).Clinicians also examined all the patients using the Ashworth Scale(AS).Internal reliability was assessed using Cronbach's coefficient α,while construct validity was determined using principal component analysis(PCA).Empirical validity was evaluated between patients with depression and those without depression by single factor analysis.Sensitivity was examined by calculating the Spearman correlation coefficient between the changes in scores of the ASPQ,the AS and the SS-QOL.RESULTS:The ASPQ had adequate internal consistency reliability(α=0.874) and sensitivity,with significant correlations between the changes in scores of the AS,the SS-QOL and the ASPQ,with three domains.In a construct validity test,six factors were extracted;the overall variance explained by all factors was 72.6%.For empirical validity,mean values of 19 items and 3 domains were all higher in the depressive patients than in the non-depressive patients.CONCLUSION:The ASPQ is a reliable and valid self-rating scale for measuring the HR-QOL in patients with post-stroke spasticity. | Yanhong Zhang Baoyan Liu Zhishun Liu Yin Wang Hong Zhao Mingjie Zi Liping Wang Hong Liu Zhen Chen Ying Xie | 2012 | Journal of Traditional Chinese Medicine2012,32,4: | 5 |
| 16 | Emplacement Mechanism of the Akebasitao Pluton:Implications for Regional Tectonic Evolution of West Junggar,NW China显示文摘Late Carboniferous to Early Permian A-type granites are extensively distributed throughout the West Junggar region,NW China,and the Akebasitao pluton is extremely distinguished among these plutons.In this paper,we reported new anisotropy of magnetic susceptible(AMS) data combine with detailed field study and audio magnetotelluric(AMT) sounding to assess the three-dimensional shape and magmatic emplacement mechanism of the Akebasitao pluton.The geological features and the AMT sounding indicate that the pluton had a slightly oblique movement of magma from northwest to southeast,which was most likely to correspond to an asymmetrical torch with a laccolith-shaped upper part,and a lower part formed by sub-vertical 'root' that was located within its northwestern part,probably controlled by the NE-trending Anqi fault.The AMS fabrics of aU the specimens reveal a low P_j value(mean of 1.02) and a low T value(mean of-0.024),suggesting that the deformation of the AMS ellipsoid is relatively weak.The specimens exhibit both oblate and prolate shapes of the AMS ellipsoid.Magnetic lineations and foliations are randomly distributed throughout the pluton without any preferred orientation.These AMS patterns indicate that the pluton formed in a relatively stable structural environment with no regional extrusion.Therefore,we propose a complex emplacement process in which the magmas reached the shallower crust levels via deep-faults and subsequently occupied the room created by doming,accompanied by sloping near the pluton roof.Additionally,the regional tectonic setting was relatively stable during the emplacement of the Akebasitao pluton,indicating the termination of compressional orogeny during the late Late Carboniferous in the West Junggar region.This conclusion perfectly coincides with the regional tectonic paleogeography,magmatic system,and paleostress field. | ZHANG Pan WANG Guocan LI Yongtao ZHANG Shengye PENG Chao ZHAO Hongwei ZHA Yanhong | 2017 | Acta Geologica Sinica(English Edition)2017,91,3: | 5 |
| 17 | Compositions of aliphatic des-A-triterpenes in the Hani peat deposit,Northeast China and its biological significance显示文摘Aliphatic des-A-triterpenes,the degradation products of pentacyclic triterpenes have been tentatively assigned in samples taken from a 963-cm-thick peat sequence from the Hani region of Northeast China using gas chromatography-mass spectrometry(GC-MS)in order to understand and identify these des-A-triterpenes response to climate and ecology.The study indicates that aliphatic des-A-triterpenes are abundant in the Hani peat bog.The high relative abundance of the total des-A-triterpenes mainly occurs at the Holocene periods and is corresponding to the low sedimentation rate.The mechanism of des-A-triterpenes accumulation is not consistent with the previous studies.It is proposed that the biological community is also one influence factor.The obvious stage variations of the total des-A-triterpenes in the whole sequence reveal the different biological(microbes and plants) processes and responses,possibly revealing the four large replacements of biological community and functional composition in the swamp environment over the 16000 cal a BP.The low total des-A-triterpenes values occur at about 10200,8700,7700,6600,4480-3940 and 3040 cal a BP,reflecting the multiple millennial micro-environment oscillations under the macro-environment of the swamp during the Holocene.The ratios of diene and monoene des-A-triterpenes(DT/MT),des-A-lupane and diene and monoene des-A-triterpenes(DL/(DT+MT)),ratios ofindividual compounds exhibit vertical opposite to the total des-A-triterpenes. Namely,these ratios are high during the last deglaciation and late Holocene whereas they are low at other periods,indicating different compounds have different responses to micro-environment and microbial activities.This study discusses the diversity of biological community and biological functional composition response to micro-environment,which not only provides the complement in Northeast China,but also bears important fundamental information for the implication to ecological environment in the future. | ZHENG YanHong ZHOU WeiJian LIU Zhao CHEN QingMin YU XueFeng LIU XiaoMin | 2010 | Chinese Science Bulletin2010,55,21: | 5 |
| 18 | Diversity of culturable heterotrophic bacteria from the Mariana Trench and their ability to degrade macromolecules显示文摘The Mariana Trench is the deepest location on earth and harbors unique microbial communities as evidenced by 16S rRNA gene amplicon and metagenomic sequencing.Obtaining culturable microorganisms from the Mariana Trench will contribute to a further understanding of hadal biogeochemical processes and act as a unique microbial reservoir with potential applications.Here,825 bacterial strains,identified by 16S rRNA gene sequencing,were isolated from 12 water depths(0-10,400 m)of the Mariana Trench with 2216E and R2A media at 4℃ or 28℃ on four cruises during 2015-2017.These bacteria belong to four phyla,nine classes,27 orders,45 families and 108 genera.Alphaproteobacteria,Gammaproteobacteria,Actinobacteria_c,Bacilli and Flavobacteriia were the most abundant classes,accounting for 37.9%,33.0%,11.8%,8.6%and 8.0%of the total bacterial isolates,respectively.2216E and R2A media were found to have a better selectivity to Bacilli and Flavobacteriia,respectively.Fifty strains were potential novel bacterial species with a 16S rRNA gene similarity<98.65%,and a higher percentage of novel strains were obtained from R2A than 2216E medium.Additionally,301(150 species)out of 354 strains(178 species)selected from each depth could degrade at least one of the ten kinds of macromolecules tested.These results indicate that there is a high diversity of culturable bacteria in the Mariana Trench and they can produce a variety of extracellular enzymes.Our study provides a valuable resource of microorganisms for investigating their biogeochemical roles in the Mariana Trench and for industrial applications. | Xiuxiu Zhao Jiwen Liu Shun Zhou Yanfen Zheng Yanhong Wu Kazuhiro Kogure Xiao-Hua Zhang | 2020 | Marine Life Science & Technology2020,2,2: | 5 |
| 19 | Expert consensus on early childhood caries management显示文摘Early childhood caries(ECC)is a significant chronic disease of childhood and a rising public health burden worldwide.ECC may cause a higher risk of new caries lesions in both primary and permanent dentition,affecting lifelong oral health.The occurrence of ECC has been closely related to the core microbiome change in the oral cavity,which may be influenced by diet habits,oral health management,fluoride use,and dental manipulations.So,it is essential to improve parental oral health and awareness of health care,to establish a dental home at the early stage of childhood,and make an individualized caries management plan.Dental interventions according to the minimally invasive concept should be carried out to treat dental caries.This expert consensus mainly discusses the etiology of ECC,caries-risk assessment of children,prevention and treatment plan of ECC,aiming to achieve lifelong oral health. | Jing Zou Qin Du Lihong Ge Jun Wang Xiaojing Wang Yuqing Li Guangtai Song Wei Zhao Xu Chen Beizhan Jiang Yufeng Mei Yang Huang Shuli Deng Hongmei Zhang Yanhong Li Xuedong Zhou | 2022 | International Journal of Oral Science2022,14,3: | 5 |
| 20 | Precise temporal regulation of Dux is important for embryo development显示文摘Dear Editor,Zygotic genome activation(ZGA)following fertilization is accomplished through a process termed the maternal-to-zygotic transition,during which the maternal RNAs and proteins are degraded and zygotic genome is transcriptionally activated.In mice,minor ZGA occurs from S phase of the zygote to G1 phase of the two-cell(2C)embryo,while major ZGA takes place during the middle-to-late 2C stage with a burst of transcription of totipotent cleavage stage-specific genes and retrotransposons. | Mingyue Guo Yanping Zhang Jianfeng Zhou Yan Bi Junqin Xu Ce Xu Xiaochen Kou Yanhong Zhao Yanhe Li Zhifen Tu Kuisheng Liu Jiaming Lin Peng Yang Shaorong Gao Yixuan Wang | 2019 | Cell Research2019,29,11: | 5 |
