| 2 | Genotypic Characterization of Methicillin-resistant Staphylococcus aureus Isolated from Pigs and Retail Foods in China显示文摘Objective To investigate the genotypic diversity of Methicillin-resistant Staphylococcus aureus(MRSA) isolated from pigs and retail foods from different geographical areas in China and further to study the routes and rates of transmission of this pathogen from animals to food. Methods Seventy-one MRSA isolates were obtained from pigs and retail foods and then characterized by multi-locus sequencing typing(MLST), spa typing, multiple-locus variable number of tandem repeat analysis(MLVA), pulsed-field gel electrophoresis(PFGE), and antimicrobial susceptibility testing. Results All isolated MRSA exhibited multi-drug resistance(MDR). Greater diversity was found in food-associated MRSA(7 STs, 8 spa types, and 10 MLVA patterns) compared to pig-associated MRSA(3 STs, 1 spa type, and 6 MLVA patterns). PFGE patterns were more diverse for pig-associated MRSA than those of food-associated isolates(40 vs. 11 pulse types). Among the pig-associated isolates, CC9-ST9-t899-MC2236 was the most prevalent clone(96.4%), and CC9-ST9-t437-MC621(20.0%) was the predominant clone among the food-associated isolates. The CC9-ST9 isolates showed significantly higher antimicrobial resistance than other clones. Interestingly, CC398-ST398-t034 clone was identified from both pig-and food-associated isolates. Of note, some community-and hospital-associated MRSA strains(t030, t172, t1244, and t4549) were also identified as food-associated isolates. Conclusion CC9-ST9-t899-MC2236-MDR was the most predominant clone in pigs, but significant genetic diversity was observed in food-associated MRSA. Our results demonstrate the great need for improved surveillance of MRSA in livestock and food and effective prevention strategies to limit MDR-MRSA infections in China. | WANG Wei LIU Feng ZULQARNAIN Baloch ZHANG Cun Shan MA Ke PENG Zi Xin YAN Shao Fei HU Yu Jie GAN Xin DONG Yin Ping BAI Yao LI Feng Qin YAN Xiao Mei MA Ai Guo XU Jin | 2017 | Biomedical and Environmental Sciences2017，30，8： | 13 |
| 3 | Molecular organic geochemical peculiarities of lacustrine core sediments in Fildes Peninsula, King George Island, Antarctica显示文摘The peculiarities of lipids in lacustrine core sediments from Fildes Peninsula, King George Island, Antarctica, are reported. The origin of high-molecular-weight n-alkanes, alkenes, fatty acids, alcohols is supposed to be related to the abundant moss occurring in the sediments. Abundant iso- and ante/so-fatty acids that occur in the sediments indicate a relatively strong bacterial activity in non-ice-cover zone than in other regions in Antarctica. The C18:2 unsaturated fatty acids mainly originate from autochthonous algae in the sediment pool, and the C18:2/C18:0 ratios in the profile are controlled more by paleotemperatures than source assemblies. Long-chain alkenones were identified in freshwater lacustrine sediment in Antarctica for the first time, of which Prymnesiophyceae is assumed to be the source organism. High relative abundance of C37:4 homologue in long-chain alkenone well correlates to the severely cold climate in Antarctica. | ZHANG Gan SHENG Guoying PENG Ping’an ZHENG Honghan | 2000 | Chinese Science Bulletin2000，45，S1： | 13 |

| 5 | High-voltage Ride Through Strategy for DFIG Considering Converter Blocking of HVDC System显示文摘This paper presents a P-Q coordination based highvoltage ride through(HVRT) control strategy for doubly fed induction generators(DFIGs) based on a combined Q-V control and P-V de-loading control. The active/reactive power injection effect of DFIG on transient overvoltage is firstly analyzed and the reactive power capacity evaluation of DFIG considering its de-loading operation is then conducted. In the proposed strategy, the reactive power limit of DFIG can be flexibly extended during the transient process in coordination with its active power adjustment. As a result, the transient overvoltage caused by DC bipolar block can be effectively suppressed. Moreover, key outer loop parameters such as Q-V control coefficient and deloading coefficient can be determined based on the voltage level of point of common coupling(PCC) and the available power capacity of DFIG. Finally, case studies based on MATLAB/Simulink simulation are used to verify the effectiveness of the proposed control strategy. | Changping Zhou Zhen Wang Ping Ju Deqiang Gan | 2020 | Journal of Modern Power Systems and Clean Energy2020，8，3： | 10 |
| 6 | Blood Pressure Associated with Arsenic Methylation and Arsenic Metabolism Caused by Chronic Exposure to Arsenic in Tube Well Water显示文摘Objective The effects of arsenic exposure from drinking water, arsenic metabolism, and arsenic methylation on blood pressure(BP) were observed in this study. Methods The BP and arsenic species of 560 participants were determined. Logistic regression analysis was applied to estimate the odds ratios of BP associated with arsenic metabolites and arsenic methylation capability. Results BP was positively associated with cumulative arsenic exposure(CAE). Subjects with abnormal diastolic blood pressure(DBP), systolic blood pressure(SBP), and pulse pressure(PP) usually had higher urinary i As(inorganic arsenic), MMA(monomethylated arsenic), DMA(dimethylated arsenic), and TAs(total arsenic) than subjects with normal DBP, SBP, and PP. The i As%, MMA%, and DMA% differed slightly between subjects with abnormal BP and those with normal BP. The PMI and SMI were slightly higher in subjects with abnormal PP than in those with normal PP. Conclusion Our findings suggest that higher CAE may elevate BP. Males may have a higher risk of abnormal DBP, whereas females have a higher risk of abnormal SBP and PP. Higher urinary i As may increase the risk of abnormal BP. Lower PMI may elevate the BP. However, higher SMI may increase the DBP and SBP, and lower SMI may elevate the PP. | WEI Bing Gan YE Bi Xiong YU Jiang Ping YANG Lin Sheng LI Hai Rong XIA Ya Juan WU Ke Gong | 2017 | Biomedical and Environmental Sciences2017，30，5： | 9 |

| 8 | Involvement of the Mitochondrion-dependent and the Endoplasmic Reticulum Stress-signaling Pathways in Isoliquiritigenin-induced Apoptosis of HeLa Cell显示文摘Objective Isoliquiritigenin(ISL),a licorice chalconoid,is considered to be a bioactive agent with chemopreventive potential.This study investigates the mechanisms involved in ISL-induced apoptosis in human cervical carcinoma HeLa cells.Methods Cell viability was evaluated using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide(MTT)assay.Apoptosis was determined by flow cytometry using an Annexin V-FITC Apoptosis Detection Kit.The intracellular ROS levels were assessed using a 2,7-dichlorofluorescein probe assay.The mitochondrial membrane potential was measured with the dual-emission potential-sensitive probe 5,5',6,6'-tetra-chloro-1,1',3,3'-tetraethyl-imidacarbocyanine iodide(JC-1).The degradation of poly-ADP-ribose polymerase(PARP)protein,the phosphorylation of PKR-like ER kinase(PERK),the phosphorylation of the α-subunit of eukaryotic initiation factor 2(eIF2α),the expression of the 78 kD glucose-regulated protein(GRP 78),and the activation of caspase-12 were analyzed via western blot analysis.Results ISL significantly inhibited the proliferation,the increase in ROS levels and apoptotic rates of HeLa cells in a concentration-dependent manner.Moreover,ISL induced mitochondrial dysfunction,caspase activation,and PARP cleavage,which displayed features of mitochondria dependent on apoptotic signals.Besides,exposure of HeLa cells to ISL triggered endoplasmic reticulum(ER)stress,as indicated by the increase in p-eIF2α and GRP78 expression,ER stress-dependent apoptosis is caused by the activation of ER-specific caspase-12.Conclusion The findings from our study suggest that ISL-induced oxidative stress causes HeLa cell apoptosis via the mitochondrion-dependent and the ER stress-triggered signaling pathways. | YUAN Xuan ZHANG Bo GAN Lu WANG Zhen Hua YU Ba Cui LIU Liang Liang ZHENG Qiu Sheng WANGZhi Ping | 2013 | Biomedical and Environmental Sciences2013，26，4： | 8 |

| 10 | Toxicity of Graphene Quantum Dots in Zebrafish Embryo显示文摘Objective To evaluate the bio-safety of graphene quantum dots(GQDs), we studied its effects on the embryonic development of zebrafish. Methods In vivo, biodistribution and the developmental toxicity of GQDs were investigated in embryonic zebrafish at exposure concentrations ranging from 12.5-200 μg/m L for 4-96 h post-fertilization(hpf). The mortality, hatch rate, malformation, heart rate, GQDs uptake, spontaneous movement, and larval behavior were examined. Results The fluorescence of GQDs was mainly localized in the intestines and heart. As the exposure concentration increased, the hatch and heart rate decreased, accompanied by an increase in mortality. Exposure to a high level of GQDs(200 μg/mL) resulted in various embryonic malformations including pericardial edema, vitelline cyst, bent spine, and bent tail. The spontaneous movement significantly decreased after exposure to GQDs at concentrations of 50, 100, and 200 μg/mL. The larval behavior testing(visible light test) showed that the total swimming distance and speed decreased dose-dependently. Embryos exposed to 12.5 μg/mL showed hyperactivity while exposure to higher concentrations(25, 50, 100, and 200 μg/mL) caused remarkable hypoactivity in the light-dark test. Conclusion Low concentrations of GQDs were relatively non-toxic. However, GQDs disrupt the progression of embryonic development at concentrations exceeding 50 μg/mL. | WANG Zhen Guo ZHOU Rong JIANG Dan SONG Jing E XU Qian SI Jing CHEN Yun Ping ZHOU Xin GAN Lu LI Jian Zhen ZHANG Hong LIU Bin | 2015 | Biomedical and Environmental Sciences2015，28，5： | 6 |

| 13 | Fast algorithm based on triplet Markov fields for unsupervised multi-class segmentation of SAR images显示文摘Non-Gaussian triplet Markov fields (TMF) model is suitable for dealing with multi-class segmentation of non-stationary and non-Gaussian synthetic aperture radar (SAR) images.Considering the complexity of the model and algorithm,as well as the requirement of real-time,and robust and efficient processing of SAR images,a fast algorithm based on TMF for unsupervised multi-class segmentation of SAR images is proposed in this paper.For the speckle noise in SAR images,numerical characteristic,threshold selection and QuadTree decomposition criterion are researched firstly.With the new method,a SAR image can quickly be mapped into an edge-based pixon-representation,which results in a coarse decomposition in smooth regions,and a fine decomposition in edges.Then by combining TMF model with the pixon-representation of SAR image,a new potential energy function of TMF based on pixon-representation is derived.Finally,the segmentation is finished by Bayesian maximum posterior mode (MPM).The effectiveness of the fast TMF algorithm is demonstrated by applying it to simulated data and real SAR images. | WU Yan WANG Xin XIAO Ping GAN Lu LIU ChunYan LIMing | 2011 | Science China(Information Sciences)2011，54，7： | 4 |
