| 1 | Seedling growth and metal accumulation of selected woody species in copper and lead/zinc mine tailings显示文摘A greenhouse pot experiment was conducted to evaluate the potential of selected woody plants for revegetation in copper (Cu) and lead/zinc (Pb/Zn) mine tailing areas.Five woody species (Amorpha fruticosa Linn,Vitex trifolia Linn.var.simplicifolia Cham,Glochidion puberum (Linn.) Hutch,Broussonetia papyrifera,and Styrax tonkinensis) and one herbaceous species (Sesbania cannabina Pers) were planted in Cu and Pb/Zn tailings to assess their growth,root morphology,nutrition uptake,metal accumulation,and translocation in plants.Amorpha fruticosa maintained normal growth,while the other species demonstrated stress related growth and root development.Sesbania cannabina showed the highest biomass among the plants,although it decreased by 30% in Cu tailings and 40% in Pb/Zn tailings.Calculated tolerance index (TI) values suggested that A.fruticosa,an N-fixing shrub,was the most tolerant species to both tailings (TI values 0.92-1.01),while S.cannabina had a moderate TI of 0.65-0.81 and B.papyrifera was the most sensitive species,especially to Pb/Zn tailings (TI values 0.15-0.19).Despite the high concentrations of heavy metals in the mine tailings and plants roots,only a small transfer of these elements to the aboveground parts of the woody plants was evident from the low translocation factor (TF) values.Among the woody plants,V.trifolia var.simplicifolia had the highest TF values for Zn (1.32),Cu (0.78),and Pb/Zn (0.78).The results suggested that A.fruticosa and S.cannabina,which have the highest tolerance and biomass production,respectively,demonstrated the potential for tailings revegetation in southern China. | Xiang Shi Xiaolei Zhang Guangcai Chen Yitai Chen Ling Wang Xiaoquan Shan | 2011 | Journal of Environmental Sciences2011，23，2： | 18 |

| 3 | Characteristics of change in water quality along reclaimed water intake area of the Chaobai River in Beijing, China显示文摘To reveal the basic characteristics and controlling factors of water quality change in the project Wenyu to Chaobai reclaimed water diversion, the water quality in the study area was monitored for one year at seven monitoring sites. Inverse geochemical models of the statistical groups were developed using PHREEQC to elucidate the hydrochemistry characteristics of reclaimed water and the factors. The monitoring results indicated that nitrogen and phosphorus contents were significantly reduced along the river mainly caused by seasonal and location variation. The pH ranged from 7.44 to 9.81. Photosynthesis of algae and denitrification in anaerobic microenvironment ultimately led to a sudden p H increase after the Jian River and the Chaobai River confluence. Mg^(2+)and SO_4^(2-) levels dropped obviously in the summer and increased in winter seasons after intersection. Na+and Cl-are relatively stable, and marked drop in the concentration only after the two rivers meet. And there is a decrease of Ca^(2+) and HCO^(3-) and increase in CO_3^(2-) during monitoring period. As a whole, the primary ions and nutrient components, including nitrogen and phosphorus, had high levels in winter. Algae's photosynthesis and respiration were observed to have an impact on the river water quality; there was precipitation–dissolution of minerals and denitrification from upstream to downstream. Inverse geochemical PHREEQC modeling confirmed that there was precipitation of aragonite or calcite, and gypsum or anhydrite in summer, and dissolution in winter; as well as precipitation of dolomite in winter, and cationic exchange and denitrification along the river. | Lei Yang Jiangtao He Yumei Liu Jian Wang Lie Jiang Guangcai Wang | 2016 | Journal of Environmental Sciences2016，28，12： | 14 |
| 4 | Groundwater hydrochemistry and isotope geochemistry in the Turpan Basin, northwestern China显示文摘The Turpan Basin is located in the arid zone of northwestern China and is a typical closed inland basin surrounded by high mountains. It is one of the most arid regions in the world and, as a result, the groundwater in this area is very important for both domestic and agricultural uses. In the present study, the relationships of major elements(K+, Na+, Ca2+, Mg2+, HCO3-, SO42- and Cl-) and environmental isotopes(δ18O, δ2H and T) in groundwater were analyzed to investigate the evolution of the regional hydrochemistry within the Turpan Basin. The hydrochemistry results demonstrate that groundwater with high total dissolved solids(TDS) concentration is dominated by sodium chloride(Na-Cl) and sodium sulfate(Na-SO4) type water, whereas that with low TDS concentration(typically from near mountain areas) is dominated by calcium bicarbonate(Ca-HCO3) type water. The evolution of groundwater hydrochemistry within the Turpan Basin is a result of calcium carbonate precipitation, evaporation concentration, cation exchange and dissolution of evaporites(i.e. halite, mirabilite and gypsum). Furthermore, evaporite dissolution associated with irrigation practice plays a key role in the groundwater salinization, especially in the central part of the basin. Environmental isotopes reveal that the groundwater is recharged by precipitation in the mountain areas and fast vertical infiltration of irrigation return flow. In the southern sub-basin the shallow groundwater and the deep groundwater is separated at a depth of about 40 m, with substantial differences in terms of hydrochemical and isotopic characteristics. The results are useful for decision making related to sustainable water resource utilization in the Turpan Basin and other regions in northwestern China. | Lu CHEN GuangCai WANG FuSheng HU YaJun WANG Liang LIU | 2014 | Journal of Arid Land2014，6，4： | 13 |
| 5 | Effects of sulfur fertilization and short-term high temperature on wheat grain production and wheat flour proteins显示文摘The content of wheat flour proteins affects the quality of wheat flour. Sulfur nutrition in wheat can change the protein content of the flour. The inconsistency and instability of wheat grain quality during grain filling under high temperature stress(HTS) are a major challenge to the production of high-quality wheat. The effects of sulfur fertilization and HTS on wheat flour protein and its components are unknown. In this study, treatments varying two factors: sulfur fertilization and exposure to short-term HTS, at 20 days postanthesis, were applied to two wheat cultivars with differing gluten types. Plants of a stronggluten wheat(Gaoyou 2018) and a medium-gluten wheat(Zhongmai 8) were grown in pots in Beijing in 2015–2017. HTS significantly increased the contents of total protein, albumin,gliadin, glutenin, Cys, and Met in wheat kernels, but reduced grain yield, grain weight,protein yield, globulin content, and total starch accumulation. The HTS-induced increase in total protein amount was closely associated with nitrate reductase(NR) and glutamine synthetase(GS) activities in flag leaves. Sulfur fertilization increased grain and protein yields; grain weight; total protein, albumin, gliadin, glutenin, and globulin contents; protein yield; total starch; Cys, Met; and NR and GS activities. HTS and sulfur fertilization had larger effects on the strong-than on the medium-gluten cultivar. Sulfur fertilization also alleviated the negative effects of HTS on grain yield, protein yield, and starch content.Thus, growing wheat with additional soil sulfur can improve the quality of the flour. | Zhiqiang Tao Xuhong Chang Demei Wang Yanjie Wang Shaokang Ma Yushuang Yang Guangcai Zhao | 2018 | The Crop Journal2018，6，4： | 11 |

| 7 | Effects of tridimensional uniform sowing on water consumption, nitrogen use, and yield in winter wheat显示文摘Wheat is a staple crop worldwide, but yields may diminish as climate change causes increasingly unpredictable patterns of precipitation and soil nutrient availability. Farmers are thus challenged to maximize planting efficiency to increase yield, while also improving their resource use efficiency. In this study the effectiveness of tridimensional uniform sowing was tested across a range of planting densities for winter wheat crops on the North China Plain. Tridimensional uniform sowing was tested against conventional drilling at three planting densities (180 × 104, 270 × 104, and 360 × 104 plants ha 1) and assessed for water consumption, biomass, nitrogen uptake and allocation, and aspects of yield. The tridimensional uniform sowing treatment outperformed the conventional drilling treatment in most metrics and at most planting densities, while performing markedly better at higher planting densities. Water consumption decreased and nitrogen efficiency increased. Tiller number and percentage of productive tillers, leaf area index, dry weight, and yield increased without a significant decline in grain protein. Nitrogen allocation was more efficient under tridimensional uniform sowing than with conventional drilling, and also varied according to annual precipitation and planting density. Both yield and grain protein contents were significantly correlated with the amount of pre-anthesis accumu- lated nitrogen translocated from vegetative organs to kernels after anthesis. Overall, a density of 270 × 104 plants ha 1 provided the highest water use efficiency and grain yield. Tridimensional uniform sowing will benefit farmers by forming stronger overall crops, promoting the coordinated improvement of yield, nitrogen uptake and efficiency, and increasing grain protein content at higher planting densities. | Zhiqiang Tao Shaokang Ma Xuhong Chang Demei Wang Yanjie Wang Yushuang Yang Guangcai Zhao Jiancang Yang | 2019 | The Crop Journal2019，7，4： | 8 |
| 8 | Active Fault Exploration and Seismic Hazard Assessment in Fuzhou City显示文摘It has been proven by a number of earthquake case studies that an active fault-induced earthquake beneath a city can be devastating. It is an urgent issue for seismic hazard reduction to explore the distribution of active faults beneath the urban area and identify the seismic source and the risks underneath. As a pilot project of active fault exploration in China, the project, entitled “Active fault exploration and seismic hazard assessment in Fuzhou City', started in early 2001 and passed the check before acceptance of China Earthquake Administration in August 2004. The project was aimed to solve a series of scientific issues such as fault location, dating, movement nature, deep settings, seismic risk and hazard, preparedness of earthquake prevention and disaster reduction, and etc. by means of exploration and assessment of active faults by stages, i.e., the preliminary survey and identification of active faults in target area, the exploration of deep seismotectonic settings, the risk evaluation of active seismogenic faults, the construction of geographic information system of active faults, and so on. A lot of exploration methods were employed in the project such as the detection of absorbed mercury, free mercury and radon in soil, the geological radar, multi-channel DC electrical method, tsansient electromagnetic method, shallow seismic refraction and reflection, effect contrast of explored sources, and various sounding experiments, to establish the buried Quaternary standard section of the Fuzhou basin. By summing up, the above explorations and experiments have achieved the following results and conclusions: (1)The results of the synthetic pilot project of active fault exploration in Fuzhou City demonstrate that, on the basis of sufficient collection, sorting out and analysis of geological, geophysical and borehole data, the best method for active fault exploration (location) and seismic risk assessment (dating and characterizing) in urban area is the combination of various approaches, that is, the possible location of active fault determined by using geochemical exploration as a guide “scout', the shallow seismic sounding as the main tool, the electromagnetic method as a supplement, establishing the standard Quaternary profile or stratigraphic sequence from drilling and various geophysical parameters from borehole logs as methods to correct and verify the data above. And in addition, the method also includes the field surveys on fault exposures, trenching, paleoearthquake investigation, dating and comparison of lithology, strata sequence, absolute or relative ages of the cores on the two sides of buried faults. (2)The Fuzhou basin locates under the regional seismotectonic settings which have the potential of moderate earthquake. Comparatively, the region is less affected by the “Taiwan dynamic Antenna'; (3)The activity of the major faults in Fuzhou basin is weak in general. All the six identified target faults are not Holocene faults, among which the Bayi Reservoir-Shanggan fault and the Minhou-Nanyu fault are dormant at least since the mid Epipleistocene time, and the rest are dormant since the Epipleistocene time; (4)In terms of deep-seated structures beneath the basin, there is no evidence indicating the possible occurrence of the underneath strong destructive earthquakes. The adjacent Changle-Zhao’an fault zone is the potential seismic source which may possibly affect Fuzhou City; (5)There exists potential of moderate-strong earthquake on the major faults of the region, but the probability is low; (6)The seismic hazards are weak in the region and the surface earthquake fractures are not likely to occur; (7)The first geographic information system of active faults is developed with functions of information query and display, data management, analysis and processing, etc. | Zhu Jinfang Huang Zonglin Xu Xiwei Zheng Rongzhang Fang Shengmin Bai Denghai Wang Guangcai Min Wei Wen Xueze Han Zhujun | 2005 | Earthquake Research in China2005，19，3： | 7 |
| 9 | Coseismic response of groundwater level in the Three Gorges well network and its relationship to aquifer parameters显示文摘The 12 May 2008 Ms 8.0 Wenchuan earthquake caused notable changes in the water levels of wells in the Three Gorges area. This work examines the relationship between these coseismic changes in water level and the changes in aquifer parameters. Three wells in the area with good responses to earth tide were chosen for analysis. Water-level data from February to June 2008 were used to calculate the aquifer transmissivity, permeability and specific storage of the rocks, and analyze the relationship between the coseismic responses of the wells and their aquifer parameters. The results show that the Wenchuan earthquake changed these parameters considerably, thereby controlling co- and postseismic variations of water level. The values of these parameters prior to the earthquake are linearly related with the amplitudes of coseismic variations in water level. The larger the aquifer transmissivity, the more remarkable the coseismic change in water level. During the earthquake, changes in aquifer parameters were found to be associated with coseismic variations in water level, with the larger changes occurring when the coseismic variation in water level was larger. The tectonic setting has a certain degree of influence on the co- and postseismic changes in water level. The permeability structures of the fault zone appear to determine the manner of coseismic variation in water level. Moreover, it seems that the water level in wells where groundwater converges more easily can recover faster following an earthquake. Insight from this study helps to improve understanding of the characteristics of water-level changes caused by earthquakes. | SHI ZheMing WANG GuangCai LIU ChengLong MEI JianChang WANG JinWei FANG HuiNa | 2013 | Chinese Science Bulletin2013，58，25： | 6 |

| 11 | Complex fields in heterogeneous materials under shock:modeling, simulation and analysis显示文摘In this mini-review we summarize the progress of modeling, simulation and analysis of shock responses of heterogeneous materials in our group in recent years. The basic methodology is as below. We first decompose the problem into different scales. Construct/Choose a model according to the scale and main mechanisms working at that scale. Perform numerical simulations using the relatively mature schemes. The physical information is transferred between neighboring scales in such a way: The statistical information of results in smaller scale contributes to establishing the constitutive equation in larger one. Except for the microscopic Molecular Dynamics(MD) model, both the mesoscopic and macroscopic models can be further classified into two categories,solidic and fluidic models, respectively. The basic ideas and key techniques of the MD, material point method and discrete Boltzmann method are briefly reviewed. Among various schemes used in analyzing the complex fields and structures, the morphological analysis and the home-built software, GISO, are briefly introduced. New observations are summarized for scales from the larger to the smaller. | AiGuo Xu GuangCai Zhang YangJun Ying Cheng Wang | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，5： | 4 |
| 12 | Deformation Behavior of the Zr_(53.5)Cu_(26.5)Ni_5Al_(12)Ag_3 Bulk Metallic Glass Over a Wide Range of Strain Rate and Temperatures显示文摘The stress–strain relations for the Zr53.5Cu26.5Ni5Al12Ag3 bulk metallic glass(BMG) over a broad range of temperatures(room temperature to its supercooled liquid region) and strain rates(10-4to 10-1s-1) were established in uniaxial compression using a thermal-mechanical simulation system. The superplastic flow was seen above its glass transition temperature(Tg = 694 K) and strain rates of up to 10-1s-1from the variation of stress–strain curves. A deformation map of strain rate vs temperature of Zr53.5Cu26.5Ni5Al12Ag3 was obtained, which was mainly composed of homogeneous and inhomogeneous deformation regions,the former featuring either Newtonian or non-Newtonian flow while the latter characterizing linear elastic behavior followed by shear localization, respectively. A phenomenological constitutive equation used to describe a master curve of viscosity with respect to the strain rate was obtained by fitting the experimental results, which determines the viscosity of the present alloy at the temperature near and above Tg. The results show the Zr53.5Cu26.5Ni5Al12Ag3 BMG is the subject suitable for net shape forming process at the supercooled liquid region. | Guangcai Ma Zhengwang Zhu Zheng Wang Haifeng Zhang | 2015 | Journal of Materials Science & Technology2015，31，9： | 4 |
| 13 | Hydrochemical Dynamic Characteristics and Evolution of Underground Brine in the Mahai Salt Lake of the Qaidam Basin Qinghai-Tibet Plateau显示文摘The mineral rock salts present in the Mahai Salt Lake of the Qaidam basin exhibit high solubilities in water. In addition, the multicomponent underground brine exhibits a high salinity and is easily precipitated. In the natural state, brine transport in the brine layer is extremely slow, and the brine is in a relatively stable chemical equilibrium state with the rock salt media. However, during mining, both the seepage and the chemical fields fluctuate significantly, thereby disrupting the equilibrium and leading to variations in the chemical composition and dynamic characteristics of the brine. Therefore, we selected underground brine from the Mahai Salt Lake, collecting a total of 183 brine samples over three stages of mining(i.e., the early stage of underground brine extraction, the initial stage of mining, and the later stage of mining). Using a range of analytical techniques, the chemical dynamics of the underground brine water and its evolution were systematically studied. We found that evaporation and enrichment were the main mechanisms of underground brine evolution in the Mahai Salt Lake, with cation exchange and mineral dissolution/precipitation being key factors in determining the dynamic characteristics and evolution of the brine. | HU Shuya ZHAO Quansheng WANG Guangcai ZHANG Jianwei FENG Juan | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 4 |
| 14 | Removing barometric pressure effects from groundwater level and identifying main influential constituents显示文摘Changes in barometric pressure can affect the micro-dynamic state of groundwater level.The groundwater level data carry a lot of important information of tectonic activity and earthquakes.It is very significant to eliminate the barometric pressure effects from the groundwater level data in order to recognize seismic anomalies effectively.With the analysis of the main influential constituents of barometric pressure and their changes,we can have a better understanding of the changes of the aquifer medium,which can provide useful information for earthquake prediction.Taking the May 12,2008 Wenchuan earthquake as an example,this paper deals with the influence of barometric pressure on groundwater level based on observational data from Nanxi,Qionglai and Chaohu wells.The methods of the linear regression and the deconvolution regression were employed to remove the barometric pressure from the groundwater level data.The harmonic analysis and the spectral analysis were used to recognize the main influential waves of barometric pressure effect.A comparison was conducted on the main influential waves before and after the earthquake.The results showed that the main influential waves of barometric pressure effect changed and the amplitudes of all constituents also changed.This phenomenon may result from the characteristics of the influential constituents of pressure,or from the changes of the aquifer medium,which were caused by the earthquake. | ZHAO Dan WANG GuangCai | 2013 | Science China(Technological Sciences)2013，56，1： | 3 |
| 15 | Distribution of δ^(34)S and δ^(18)O in SO_4^(2-) in Groundwater from the Ordos Cretaceous Groundwater Basin and Geological Implications显示文摘The Ordos Cretaceous Groundwater Basin,located in an arid-semiarid area in northwestern China,is a large-style groundwater basin.SO_4^(2-) is one of the major harmful components in groundwater.Dissolved SO_4^(2-) concentrations,andδ^(34)S-SO_4^(2-) andδ^(18)O-SO_4^(2-) in groundwater from 14 boreholes and in gypsum from aquifer were analyzed.Results show that SO_4^(2-) in shallow groundwaters originates from precipitation,sulfide oxidation,and dissolution of stratum sulphate,with a big range ofδ^(34)S values,from-10.7‰to 9.2‰,and addition of SO_4^(2-) in deep groundwater results from dissolution of stratum sulphate,with biggerδ^(34)S values,from 7.8‰to 18.5‰,compared with those in shallow groundwater.This research also indicates that three types of sulphate are present in the strata,and characterized by highδ^(34)S values and highδ^(18)O values-style,highδ^(34)S values and middleδ^(18)O valuesstyle, middleδ^(34)S values and lowδ^(18)O values-style,respectively.Theδ^(34)S-SO_4^(2-) andδ^(18)O-SO_4^(2-) in groundwater have a good perspective for application in distinguishing different groundwater systems and determining groundwater circulation and evolution in this area. | YANG Yuncheng SHEN Zhaoli WEN Dongguang HOU Guangcai SHE Hongquan ZHAO Zhenhong WANG Dong LI Jingwen | 2010 | Acta Geologica Sinica(English Edition)2010，84，2： | 3 |
| 16 | Advances in research on earthquake fluids hydrogeology in China:a review显示文摘Monitoring of subsurface fluid(underground fluid)is an important part of efforts for earthquake prediction in China.The nationwide network,which monitors groundwater level,water temperature,and radon and mercury in groundwater,has been constructed in the last decades.Large amounts of abnormal fluid changes before and after major earthquakes have been recorded,providing precious data for research in earthquake sciences.Many studies have been done in earthquake fluid hydrogeology in order to probe the nature of the earthquake.Much progress in earthquake fluid hydrogeology has been made in the last decades.The paper provides a review of the advances in research on earthquake fluid hydrogeology over the last40 years in China.It deals with the following five aspects:(1)an introduction to the development history of monitoring networks construction;(2)cases of different subsurface fluid changes recorded before some majorearthquakes which occurred in the last decades;(3)characteristics of subsurface fluid changes following major earthquakes;(4)mechanism of subsurface fluid changes before and following earthquakes;(5)application of earthquake fluids in the hydrogeology field. | Zheming Shi Guangcai Wang Chenglong Liu | 2013 | Earthquake Science2013，26，6： | 3 |
| 17 | Relationship between the Earth tidal factor and phase lag of groundwater levels in confined aquifers and the Wenchuan M_s8.0 earthquake of 2008显示文摘This work focuses on variations of the Earth tidal factor and phase lag derived from groundwater observations before and after major earthquakes.It is based on an analysis of the data from four observational wells at boundaries between distinct active blocks of China mainland.These wells are also situated on several active fault zones and have exhibited considerable responses to the Wenchuan Ms8.0 earthquake of 2008 in China.We collected hourly records of water levels of these wells from 2007to 2009 and processed these data for analysis.The tidal factors,phase lags,and phase-difference changes of tidal residuals of each well were calculated.We found that when the Wenchuan quake happened,the tidal factors of the 4 wells were changing rapidly,while their phase lags and phase differences of tidal residuals declined swiftly,which may reflect the stress and strain changes of the well-aquifer system during the seismic generation. | SHI ZheMing WANG GuangCai | 2013 | Science China Earth Sciences2013，56，10： | 3 |
| 18 | Porosity Distribution Characteristics and Geological Analysis of Brine Storage Medium in the Qaidam Basin, Western China显示文摘Underground brine is an unusual water resource that contains abundant mineral resources. It is distributed widely in the Qaidam Basin, western China, a hyperarid inland basin located in the northern Tibetan Plateau. Pores in the brine storage medium act as storage space and transmission channels of underground brine. Therefore, the porosity of brine storage medium determines its ability to store brine. In this study, Mahai Salt Lake was used as the research area as a modern saline lake located in the north area of the Qaidam Basin. A total of 100 porosity samples were collected from eight sampling points in two profiles of the research area at sampling depths of 1.30–314.78 m. The porosity distribution characteristics and influencing factors in brine storage medium were analysed according to the measured porosity data. Based on analysis of the pore structure characteristics, the brine storage medium contains intercrystalline pores, unlike conventional freshwater storage mediums. Moreover, the primary salt rock is susceptible to dissolution by lighter brine, facilitating the formation of secondary porosity. Due to the formation of secondary pores, a porosity greater than 20% remains even at buried depths greater than 100 m. Based on the geological statistical analysis, due to the geographic location, salt formation time, and depositional environment, the porosity values of Mahai Salt Lake do not exhibit a wider distribution, but also show more extreme values than a nearby salt lake. Based on the porosity characteristics by depth, due to the presence of secondary pores, flooding, stratigraphic static pressure, and other factors, porosity shows fluctuations with increasing depth. | HU Shuya XIAO Changlai LIANG Xiujuan ZHAO Quansheng WANG Guangcai ZHANG Jianwei FENG Juan | 2018 | Chinese Geographical Science2018，28，4： | 2 |
| 19 | Comparison of gut microbiota in autism spectrum disorders and neurotypical boys in China:A case-control study显示文摘Background:Autism spectrum disorders(ASDs)are a set of complex neurobiological disorders.Growing evidence has shown that the microbiota that resides in the gut can modulate brain development via the gut–brain axis.However,direct clinical evidence of the role of the microbiota–gut–brain axis in ASD is relatively limited.Methods:A case-control study of 71 boys with ASD and 18 neurotypical controls was conducted at China-Japan Friendship Hospital.Demographic information and fecal samples were collected,and the gut microbiome was evaluated and compared by 16S ribosomal RNA gene sequencing and metagenomic sequencing.Results:A higher abundance of operational taxonomic units(OTUs)based on fecal bacterial profiling was observed in the ASD group.Significantly different microbiome profiles were observed between the two groups.At the genus level,we observed a decrease in the relative abundance of Escherichia,Shigella,Veillonella,Akkermansia,Provindencia,Dialister,Bifidobacterium,Streptococcus,Ruminococcaceae UCG_002,Megasphaera,Eubacterium_coprostanol,Citrobacter,Ruminiclostridium_5,and Ruminiclostridium_6 in the ASD cohort,while Eisenbergiella,Klebsiella,Faecalibacterium,and Blautia were significantly increased.Ten bacterial strains were selected for clinical discrimination between those with ASD and the neurotypical controls.The highest AUC value of the model was 0.947.Conclusion:Significant differences were observed in the composition of the gut microbiome between boys with ASD and neurotypical controls.These findings contribute to the knowledge of the alteration of the gut microbiome in ASD patients,which opens the possibility for early identification of this disease. | Fang Ye Xinying Gao Zhiyi Wang Shuman Cao Guangcai Liang Danni He Zhitang Lv Liming Wang Pengfei Xu Qi Zhang | 2021 | Synthetic and Systems Biotechnology2021，6，2： | 2 |
