1Antidiabetic Effects of Gegen Qinlian Decoction via the Gut Microbiota Are Attributable to Its Key Ingredient Berberine显示文摘Gegen Qinlian Decoction(GQD),a traditional Chinese medicine(TCM)formula,has long been used for the treatment of common metabolic diseases,including type 2 diabetes mellitus.However,the main limitation of its wider application is ingredient complexity of this formula.Thus,it is critically important to identify the major active ingredients of GQD and to illustrate mechanisms underlying its action.Here,we compared the effects of GQD and berberine,a hypothetical key active pharmaceutical ingredient of GQD,on a diabetic rat model by comprehensive analyses of gut microbiota,short-chain fatty acids,proinflammatory cytokines,and ileum transcriptomics.Our results show that berberine and GQD had similar effects on lowering blood glucose levels,modulating gut microbiota,inducing ileal gene expression,as well as relieving systemic and local inflammation.As expected,both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria,including Faecalibacterium and Roseburia,thereby attenuating intestinal inflammation and lowering glucose.Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with berberine or GQD.Moreover,concentration of serum proinflammatory cytokines and expression of immune-related genes,including Nfkb1,Stat1,and Ifnrg1,in pancreatic islets were significantly reduced after treatment.Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota.The strategy employed would facilitate further standardization and widespread application of TCM in many diseases.Xizhan Xu Zezheng Gao Fuquan Yang Yingying Yang Liang Chen Lin Han Na Zhao Jiayue Xu Xinmiao Wang Yue Ma Lian Shu Xiaoxi Hu Na Lyu Yuanlong Pan Baoli Zhu Linhua Zhao Xiaolin Tong Jun Wang 2020Genomics, Proteomics & Bioinformatics2020,18,6:29
2Inulin Can Alleviate Metabolism Disorders in ob/ob Mice by Partially Restoring Leptinrelated Pathways Mediated by Gut Microbiota显示文摘Inulin has been used as a prebiotic to alleviate glucose and lipid metabolism disorders in mice and humans by modulating the gut microbiota. However, the mechanism underlying the alleviation of metabolic disorders by inulin through interactions between the gut microbiota and host cells is unclear. We use ob/ob mice as a model to study the effect of inulin on the cecal microbiota by16 S rRNA gene amplicon sequencing and its interaction with host cells by transcriptomics. The inulin-supplemented diet improved glucose and lipid metabolism disorder parameters in ob/ob mice,alleviating fat accumulation and glucose intolerance. The a diversity of gut microbial community of ob/ob mice was reduced after inulin treatment, while the b diversity tended to return to the level of wild type mice. Interestingly, Prevotellaceae UCG 001(family Prevotellaceae) was obviously enriched after inulin treatment. A comparative analysis of the gene expression profile showed that the cecal transcriptome was changed in leptin gene deficiency mice, whereas the inulin-supplemented diet partially reversed the changes in leptin gene-related signaling pathways, especially AMPK signaling pathway, where the levels of gene expression became comparable to those in wild type mice.Further analysis indicated that Prevotellaceae UCG 001 was positively correlated with the AMPK signaling pathway, which was negatively correlated with markers of glycolipid metabolism disorders. Our results suggest that the inulin-supplemented diet alleviates glucose and lipid metabolism disorders by partially restoring leptin related pathways mediated by gut microbiota.Xiaofeng Song Liang Zhong Na Lyu Fei Liu Boxing Li Yanan Hao Yong Xue Jing Li Yuqing Feng Yue Ma Yongfei Hu Baoli Zhu 2019Genomics, Proteomics & Bioinformatics2019,17,1:12
3CRISPR/Cas9-mediated multiple gene editing in Brassica oleracea var.capitata using the endogenous tRNA-processing system显示文摘Cabbage(Brassica oleracea var.capitata)is a biennial plant with strong self-incompatibility and an obligate requirement for prolonged vernalization by exposure to low temperatures to induce flowering.These characteristics significantly increase the difficulty of exploiting novel germplasm induced by physical or chemical mutagens.In this study,we report a CRISPR/Cas9 gene-editing system based on endogenous tRNA processing to induce high efficiency and inheritable mutagenesis in cabbage.Using the phytoene desaturase gene BoPDS,the S-receptor kinase gene BoSRK,and the male-sterility-associated gene BoMS1 as the target genes,multisite and multiple gene mutations were achieved using a construct with tandemly arrayed tRNA-sgRNA architecture to express multiple sgRNAs.The BoSRK3 gene mutation suppressed self-incompatibility completely,converting the self-incompatible line into a self-compatible line.In addition,the BoMS1 gene mutation produced a completely male-sterile mutant,which was highly cross compatible with its nonmutant isoline at the flowering stage as a result of a simultaneous BoSRK3 gene mutation,enabling the economic propagation of the male-sterile line through bee-mediated cross-pollination.Interestingly,higher site mutation efficiency was detected when a guide sequence was inserted into a location in the tandemly arrayed tRNA-sgRNA architecture that was distal from the upstream Pol III promoter.In addition,mutation sites were also detected in the paralogous genes of the BoPDS and BoSRK genes that had fully consistent sequences or base mismatches but beyond the“seed”region in the spacer sequence compared with the target sgRNAs.Collectively,our results demonstrate that the CRISPR/Cas9 system,coupled with an endogenous tRNA-processing system,is an efficient tool to improve cabbage traits.Cunfa Ma Chenzeng Zhu Min Zheng Mengci Liu Dejun Zhang Baoli Liu Qinfei Li Jun Si Xuesong Ren Hongyuan Song 2019Horticulture Research2019,6,1:8
4Vaterite or aragonite observed in the prismatic layer of freshwater-cultured pearls from South China显示文摘A prismatic layer is present in both freshwater-cultured pearls and seawater-cultured pearls. The phase structure of the prismatic layer of freshwater-cultured pearls is investigated for the first time and novel findings are reported in this paper. X-ray diffraction (XRD), optical microscopy (OM) and micro-infrared (IR) spectroscopy were used to characterize the crystallized layers of high and low-quality freshwater-cultured pearls. Results show that there is no calcite in the prismatic layer of freshwater-cultured pearls, which is different from what was found for seawater-cultured pearls. We found that an aragonite phase was present in the prismatic layer of high-quality freshwater-cultured pearls and that a vaterite or aragonite phase was present in low-quality pearls. Based on this study an internal factor that influences the quality of freshwater-cultured pearls is discussed.Hongyan Ma Anan Su Beili Zhang Ru-Kang Li Longchang Zhou Baoli Wang 2009Progress in Natural Science:Materials International2009,19,7:7

6The temporal dynamics of antimicrobial-resistant Salmonella enterica and predominant serovars in China显示文摘Salmonella enterica is one of the most common bacterial pathogens in humans and animals.Systematic studies on the trends and geographical distribution of antimicrobial-resistant Salmonella and dominant serovars have been well studied in European and American countries while not in China.Here,taking the One-Health strategy,we used>35000 Salmonella enterica isolates to explore the temporal and spatial dynamics of dominant serovars in China.We found that Salmonella Typhimurium was the dominant serovar causing human infection in China,which was consistent with Australia but inconsistent with North American and European countries.The proportion of Salmonella serovars Typhimurium,London,Rissen,Corvallis,Meleagridis,Kentucky,and Goldcoast showed an increasing trend during 2006-2019.We randomly selected 1962 isolates for comparative genomics and antimicrobial resistance studies and found that the number of antibiotic resistance genes(ARGs)per isolate increased 1.84 and 2.69 times of human and non-human origins,respectively,spanning 14 years.The proportion of antimicrobial-resistant Salmonella isolates had an increasing trend during 2006-2019,especially beta-lactam,quinolone,tetracycline,and rifampicin resistance.Moreover,we found that higher diversity of sequence types(STs)in S.Typhimurium than in other serovars,ST34 from pig and ST 19 from chicken origin,were mainly associated with isolates causing child and adult gastro-infection,respectively.Our results fill in the data gap on the trends of dominant serovars and antimicrobial resistance of Salmonella enterica in China.These data provide useful information for public health decision-makers prioritizing interventions for foodborne diseases and food safety.Yanan Wang Yue Liu Na Lyu Zhiyuan Li Sufang Ma Demin Cao Yuanlong Pan Yongfei Hu Hua Huang George F.Gao Xuebin Xu Baoli Zhu 2023National Science Review2023,10,3:4
7Effects of river damming on biogenic silica turnover:implications for biogeochemical carbon and nutrient cycles显示文摘Rivers link terrestrial ecosystems and marine ecosystems, and they transport large amounts of substances into oceans each year, including several forms of silicon(Si), carbon(C), and other nutrients. However, river damming affects the water flow and biogeochemical cycles of Si, C, and other nutrients through biogeochemical interacting processes. In this review, we first summarize the current understanding of the effects of river damming on the processes of biogeochemical Si cycle, especially the source, composition, and recycling process of biogenic silica(BSi). Then, we introduce dam impacts on the cycles of C and some other nutrients. Dissolved silicon in rivers is mainly released from phytolith dissolution and silicate weathering. BSi in suspended matter or sediments in most rivers mainly consists of phytoliths and mainly originates from soil erosion. However, diatom growth and deposition in many reservoirs formed by river interception may significantly increase the contribution of diatom Si to total BSi, and thus significantly influence the biogeochemical Si,C, and nutrient cycles. Yet the turnover of phytoliths and diatoms in different rivers formed by river damming is still poorly quantified. Thus, they should be further investigated to enhance our understanding about the effects of river damming on global biogeochemical Si, C and nutrient cycles.Nan Ma Zhaoliang Song Baoli Wang Fushun Wang Xiaomin Yang Xiaodong Zhang Qian Hao Yuntao Wu 2017Acta Geochimica2017,36,4:3

9CO_2 emission and organic carbon burial in the Xinanjiang Reservoir显示文摘In order to understand the effect of river impoundment on carbon dynamics, a large reservoir in a subtropical area, the Xinanjiang Reservoir, was investigated in detail. CO_2 emissions from the water–air interface was studied, as was organic carbon burial in sediment. The results show a significant seasonal difference in CO_2 emissions. River impoundment led to the enhancement of aquatic photosynthesis, generating large amounts of authigenic organic carbon that was then buried in sediment.Fushun Wang Baoli Wang Tao Zhou Tianyu Chen Jing Ma 2017Acta Geochimica2017,36,3:2

13Rapid full-color Fourier ptychographic microscopy via spatially filtered color transfer显示文摘Full-color imaging is of critical importance in digital pathology for analyzing labeled tissue sections.In our previous cover story[Sci.China:Phys.,Mech.Astron.64,114211(2021)],a color transfer approach was implemented on Fourier ptychographic microscopy(FPM)for achieving high-throughput full-color whole slide imaging without mechanical scanning.The approach was able to reduce both acquisition and reconstruction time of FPM by three-fold with negligible trade-off on color accuracy.However,the method cannot properly stain samples with two or more dyes due to the lack of spatial constraints in the color transfer process.It also requires a high computation cost in histogram matching of individual patches.Here we report a modified full-color imaging algorithm for FPM,termed color-transfer filtering FPM(CFFPM).In CFFPM,we replace the original histogram matching process with a combination of block processing and trilateral spatial filtering.The former step reduces the search of the solution space for colorization,and the latter introduces spatial constraints that match the low-resolution measurement.We further adopt an iterative process to refine the results.We show that this method can perform accurate and fast color transfer for various specimens,including those with multiple stains.The statistical results of 26 samples show that the average root mean square error is only 1.26%higher than that of the red-green-blue sequential acquisition method.For some cases,CFFPM outperforms the sequential method because of the coherent artifacts introduced by dust particles.The reported CFFPM strategy provides a turnkey solution for digital pathology via computational optical imaging.JIURUN CHEN AIYE WANG AN PAN GUOAN ZHENG CAIWEN MA BAOLI YAO 2022Photonics Research2022,10,10:1

15Molecular evolution of nitrogen-containing compounds in highly mature organic matter: Implications for the hydrocarbon generation potential显示文摘Evaluating the hydrocarbon generation potential of highly mature organic matter is a key and critically challenging area of research in petroleum geochemistry. To explore this issue, we used negative ion electrospray ionization-Fourier transform-ion cyclotron resonance-mass spectrometry to investigate the molecular evolution of N-containing compounds in Carboniferous-lower Permian source rocks with a range of maturities in the northwestern Junggar Basin, China. The N1compounds formed from on-fluorescent chlorophyll catabolites(NCCs), which record the characteristics of the residual soluble organic matter. These components remain in the source rocks after hydrocarbon generation and expulsion, and enable evaluation of the hydrocarbon generation potential. The newly defined indexes of molecular evolution, which are the polymerization index P1([DBE 18+DBE 15]/[DBE 12+DBE 9]_N1) and alkylation index R1(RC_(6–35)/RC_(0–5)), combined with the vitrinite reflectance(VR_(o)) and paleo-salinity index(β-carotane/n Cmax), can identify the factors that control the evolution of highly mature organic matter. The main factor for source rocks deposited in a weakly saline environment is the maturity, but for a highly saline environment both the maturity and salinity are key factors. The high salinity inhibits the molecular polymerization of organic matter and extends the oil generation peak. Given the differences in the bio-precursors in saline source rocks, we propose a new model for hydrocarbon generation that can be used to determine the oil generation potential of highly mature organic matter.Jingkun ZHANG Jian CAO Wenxuan HU Baoli XIANG Ni ZHOU Wanyun MA 2023Science China Earth Sciences2023,66,4:0
16High-throughput fast full-color digital pathology based on Fourier ptychographic microscopy via color transfer显示文摘The usage of full-color imaging in digital pathology produces significant results.Compared with a grayscale image or a pseudocolor image containing contrast information,a full-color image can identify and detect the target object better with color texture information.Fourier ptychographic microscopy(FPM)is a high-throughput computational imaging technique that breaks the tradeoff between high resolution(HR)and a large field of view.It also eliminates the artifacts of scanning and stitching in digital pathology and improves its imaging efficiency.However,the conventional full-color digital pathology based on FPM is still time-consuming because of the repeated experiments with tri-wavelengths.A color transfer FPM approach termed“CFPM”was reported.The color texture information of a low-resolution full-color pathologic image is directly transferred to the HR grayscale FPM image captured by only a single wavelength.Both of the color space of FPM based on the standard CIE-XYZ color model and the display based on the standard RGB color space were established.Different FPM colorization schemes were analyzed and compared with 30 biological samples.Three types of evaluation approaches were provided,including the root-mean-square error(RMSE),the difference maps,and the image histogram cosine similarity.The average RMSE values of the conventional method and CFPM compared with the ground truth were 5.3%and 5.7%,respectively.Therefore,the reconstruction time is significantly reduced by 2/3 with the sacrifice of precision of only 0.4%.The CFPM method is also compatible with advanced fast FPM approaches to further reduce computation time.Yuting Gao Jiurun Chen Aiye Wang An Pan Caiwen Ma Baoli Yao 2021Science China(Physics,Mechanics & Astronomy)2021,64,11:0
17Vitamin-K2 dependent GGCX and MGP are required for homeostatic calci um regulation in epididymis显示文摘A low-calcium microenvironment is essential for spermatozoa to mature in the epididymis.Abnormal elevation of calcium concentration in the epididymal lumen will lead to premature sperm activation,decreased sperm motility,and even male fertility defects or infertility.However,the mechanism of the epididymal homeostastic calcium regulation has not been fully elucidated.Ma He Zhang Baoli Gao Dayuan Wimmie Shum Li Zhen 2021解剖学杂志2021,44,S01:0
18Investigation on effect of drag models on flow behavior of power-law fluid–solid two-phase flow in fluidized bed显示文摘In this study,a Eulerian-Eulerian two-fluid model combined with the kinetic theory of granular flow is adopted to simulate power-law fluid–solid two-phase flow in the fluidized bed.Two new power-law liquid–solid drag models are proposed based on the rheological equation of power-law fluid and pressure drop.One called model A is a modified drag model considering tortuosity of flow channel and ratio of the throat to pore,and the other called model B is a blending drag model combining drag coefficients of high and low particle concentrations.Predictions are compared with experimental data measured by Lali et al.,where the computed porosities from model B are closer to the measured data than other models.Furthermore,the predicted pressure drop rises as liquid velocity increases,while it decreases with the increase of particle size.Simulation results indicate that the increases of consistency coefficient and flow behavior index lead to the decrease of drag coefficient,and particle concentration,granular temperature,granular pressure,and granular viscosity go down accordingly.Zihan Yuan Shuyan Wang Baoli Shao Lei Xie Yujia Chen Yimei Ma 2022Particuology2022,,11:0
19Global asymptotic tracking of asymmetrical underactuated surface vessels with parameter uncertainties显示文摘In this work,we investigate the tracking control problem of asymmetrical underactuated surface vessels with parameter uncertainties.The tracking error model is frst derived via appropriate coordinate transformations,and is considered as a cascade structure composed of two subsystems.The Lyapunov redesign approach is employed to construct the control laws separately to stabilize the two subsystems with unknown model parameters.The cascade system theory is applied to prove the global uniform asymptotic convergence of the state trajectory to the reference one provided the desired yaw velocity is not vanishing.The effectiveness of the proposed control laws is verifed by simulation examples.Wenjing XIE Hailing SUN Baoli MA 2013控制理论与应用(英文版)2013,11,4:0
20Detection of Plasmid-Mediated Tigecycline Resistance Gene tet(X4) in a Salmonella enterica Serovar Llandoff Isolate显示文摘The emergence and spread of plasmid-mediated tigecycline resistance genes have attracted extensive attention worldwide.We investigated the distribution of mobile tigecycline resistance genes in Salmonella genomes generated by both our laboratory and public bacterial genomes downloaded from the NCBI GenBank.The tet(X4)-positive strains were subjected to susceptibility testing and conjugation assays.The genetic features of the tet(X4)-bearing plasmid sequence were analyzed.Here,we report the identification of the plasmid-mediated tigecycline resistance gene tet(X4)in a conjugative plasmid of the Salmonella enterica serovar Llandoff strain SH16G3606,isolated from a man in China in 2016,the first reported serovar Llandoff in China as a novel sequence type ST8300.The tet(X4)-mediated resistance phenotype was successfully transferred from the Salmonella Llandoff strain into Escherichia coli J53,resulting in a 32-fold increase in the minimal inhibitory concentration of tigecycline.The tet(X4)gene was located between two copies of ISCR2 in the plasmid pSal21GXH-tetX4.To our knowledge,this is the first report of the plasmid-mediated tigecycline resistance gene tet(X4)in a Salmonella Llandoff strain isolated from a human stool sample in China.In addition,our findings demonstrated that a total of 171 isolates are carrying tet(X)-like genes distributed in 21 countries or areas across 6 continents,posing a serious threat to humans and public health.Overall,our timely discovery of the recent emergence of the tet(X4)gene in Salmonella isolates and other Enterobacteriaceae bacteria species supports the need for rapid surveillance to prevent the tet(X)-like gene from spreading.Yanan Wang Fei Liu Xuebin Xu Hua Huang Na Lyu Sufang Ma Luping Chen Mengyu Mao Yongfei Hu Xiaofeng Song Jing Li Yuanlong Pan Aiping Wang Gaiping Zhang Baoli Zhu George F.Gao 2021Infectious Microbes & Diseases2021,3,4:0
