| 1 | Relationship between Cognition Function and Hippocampus Structure after Long-term Microwave Exposure显示文摘Objective To analyze the effects of long-term microwave exposure on hippocampal structure and function in the rat.Methods Experiments were performed on 184 male Wistar rats(three exposure groups and a sham group).Microwaves were applied daily for 6 min over 1 month at average power densities of 2.5,5,and 10 mW/cm2.Learning and memory abilities were assessed by Morris water maze.High performance liquid chromatography was used to detect neurotransmitter concentrations in the hippocampus.Hippocampal structures were observed by histopathological analysis.Results Following long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d,14 d,and 1 m in all three microwave exposure groups.Neurotransmitter concentrations of four amino acids(glutamate,aspartic acid,glycine,and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group.There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups.Further,mitochondria became swollen and cristae were disordered.The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.Conclusion These data suggest that the hippocampus can be injured by long-term microwave exposure,which might result in impairment of cognitive function due to neurotransmitter disruption. | ZHAO Li PENG Rui Yun WANG Shui Ming WANG Li Feng GAO Ya Bing DONG Ji LI Xiang SU Zhen Tao | 2012 | Biomedical and Environmental Sciences2012，25，2： | 27 |
| 2 | Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups. | YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng | 2016 | Biomedical and Environmental Sciences2016，29，3： | 18 |
| 3 | The Development of A Fluorescence Polarization Immunoassay for Aflatoxin Detection显示文摘A fluorescence polarization immunoassay(FPIA)was developed for the analysis ofaflatoxins(AFs)using an anti-aflatoxin B1(AFB1)monoclonal antibody and a novel fluorescein-labeled AFB1tracer.The FPIA showed an IC50 value of 23.33ng/mL with a limit of detection of 13.12 ng/mL for AFB1.The cross-reactivities of AFB1,AFB2,AFG1,AFG2,AFM1,and AFM2 with the antibody were100%,65.7%,143%,23.5%,111.4%,and 2%,respectively.The group-specificity of anti-AFB1mAb indicated that the FPIA could potentially be used in a screening method for the detection of total AFs,albeit not AFG2 and AFM2.The total time required for analyzing 96 samples in one microplate was less than 5 min.This study demonstrates the potential usefulness of the FPIA as a rapid and simple technique for monitoring AFs. | SHENG Ya Jie EREMIN Sergei MI Tie Jun ZHANG Su Xia SHEN Jian Zhong WANG Zhan Hui | 2014 | Biomedical and Environmental Sciences2014，27，2： | 10 |
| 4 | Antidepressant-Like Action of Single Facial Injection of Botulinum Neurotoxin A is Associated with Augmented 5-HT Levels and BDNF/ERK/CREB Pathways in Mouse Brain显示文摘The present study was designed to examine the therapeutic effects of Botulinum neurotoxin A(BoNT/A)on depression-like behaviors in mice and to explore the potential mechanisms.These results revealed that a single facial injection of BoNT/A induced a rapid and prolonged improvement of depression-like behaviors in naive and space-restriction-stressed(SRS)mice,reflected by a decreased duration of immobility in behavioral despair tests.BoNT/A significantly increased the 5-hydroxytryptamine(5-HT)levels in several brain regions,including the hippocampus and hypothalamus,in SRS mice.BoNT/A increased the expression of the N-methyl-Daspartate receptor subunits NR1 and NR2 B in the hippocampus,which were significantly decreased in SRS mice.Furthermore,BoNT/A significantly increased the expression of brain-derived neurotrophic factor(BDNF)in the hippocampus,hypothalamus,prefrontal cortex,and amygdala,which were decreased in SRS mice.Finally,BoNT/A transiently increased the levels of phosphorylated extracellular signal-regulated kinase(p-ERK)and cAMPresponse element binding protein(p-CREB),which were suppressed in the hippocampus of SRS mice.Collectively,these results demonstrated that BoNT/A treatment has antidepressant-like activity in mice,and this is associated with increased 5-HT levels and the activation of BDNF/ERK/CREB pathways in the hippocampus,supporting further investigation of BoNT/A therapy in depression. | Yang Li Jing Liu Xu Liu Cun-Jin Su Qi-Lin Zhang Zhi-Hong Wang Lei-Fang Cao Xue-Yan Guo Ya Huang Weifeng Luo Tong Liu | 2019 | Neuroscience Bulletin2019，35，4： | 10 |
| 5 | MicroTom Metabolic Network: Rewiring Tomato Metabolic Regulatory Network throughout the Growth Cycle显示文摘Tomato(Solanum lycopersicum)is a major horticultural crop worldwide and has emerged as a preeminent model for metabolic research.Although many research efforts have focused on the analysis of metabolite differences between varieties and species,the dynamics of metabolic changes during the tomato growth cycle and the regulatory networks that underlie these changes are poorly understood.In this study,we integrated high-resolution spatio-temporal metabolome and transcriptome data to systematically explore the metabolic landscape across 20 major tomato tissues and growth stages.In the resulting MicroTom Metabolic Network,the 540 detected metabolites and their co-expressed genes could be divided into 10 distinct clusters based on their biological functions.Using this dataset,we constructed a global map of the major metabolic changes that occur throughout the tomato growth cycle and dissected the underlying regulatory network.In addition to verifying previously well-established regulatory networks for important metabolites,we identified novel transcription factors that regulate the biosynthesis of important secondary metabolites such as steroidal glycoalkaloids and flavonoids.Our findings provide insights into spatiotemporal changes in tomato metabolism and generate a valuable resource for the study of metabolic regulatory processes in model plants. | Yan Li Yang Chen Lu Zhou Shengjie You Heng Deng Ya Chen Saleh Alseekh Yong Yuan Rao Fu Zixin Zhang Dan Su Alisdair R.Fernie Mondher Bouzayen Tao Ma Mingchun Liu Yang Zhang | 2020 | Molecular Plant2020，13，8： | 10 |
| 6 | Spatial Interpolation and Sample Size Optimization for Soil Copper(Cu) Investigation in Cropland Soil at County Scale Using Cokriging显示文摘Knowledge on spatial distribution and sampling size optimization of soil copper(Cu) could lay solid foundations for environmetal quality survey of agricultural soils at county scale.In this investigation,cokriging method was used to conduct the interpolation of Cu concentraiton in cropland soil in Shuangliu County,Sichuan Province,China.Based on the original 623 physicochmically measured soil samples,560,498,and 432 sub-samples were randomly selected as target variable and soil organic matter(SOM) of the whole original samples as auxiliary variable.Interpolation results using Cokriging under different sampling numbers were evaluated for their applicability in estimating the spatial distribution of soil Cu at county sacle.The results showed that the root mean square error(RMSE) produced by Cokriging decreased from 0.9 to 7.77%,correlation coefficient between the predicted values and the measured increased from 1.76 to 9.76% in comparison with the ordinary Kriging under the corresponding sample sizes.The prediction accuracy using Cokriging was still higher than original 623 data using ordinary Kriging even as sample size reduced 10%,and their interpolation maps were highly in agreement.Therefore,Cokriging was proven to be a more accurate and economic method which could provide more information and benefit for the studies on spatial distribution of soil pollutants at county scale. | PANG Su,LI Ting-xuan,WANG Yong-dong,YU Hai-ying and LI Xi College of Resource and Environmental Science,Sichuan Agricultural University,Ya’an 625014,P.R.China | 2009 | Agricultural Sciences in China2009，8，11： | 10 |

| 10 | Influencing Factors on Rice Sheath Blight Epidemics in Integrated Rice-Duck System显示文摘Sheath blight, a disease caused by the fungus Rhizoctonia solani Kuhn (anamorph), has been the most economically significant disease of rice. It was frequently reported that the disease was well-controlled in integrated rice-duck system without the employment of fungicides. However, the effecting factors behind this phenomenon were rarely reported. In this research, experiment was carried out between two treatments, rice combined with ducks (RD) and conventional rice field without ducks rearing (CK) in early season rice paddy, to investigate the variations of sclerotia in floodwater and on rice plant, microclimate 10 cm above the waterline in rice paddy and activity of protective enzymes in rice plants. The results showed that the floating sclerotia in floodwater in RD was 86-91% lower than that in CK, and adhering sclerotia in rice plant in RD was 67-78% lower than that in CK. The relative humidity tested significantly lower and light intensity tested significantly higher in RD. The temperature in the early rice growth stages in RD was slightly lower than that in CK, but it was significantly higher (32.3-36.5°C) in the middle stage rice growth stages. The polyphenoloxidase (PPO) activity in RD were lower than that in CK, but the enhanced activity of phenylalanine ammonia-lyase (PAL), peroxidase (POD) and Chitinase was observed in different stages of rice growth in RD, especially the Chitinase which showed higher activity in all investigating days. | SU Pin LIAO Xiao-lan ZHANG Ya HUANG Huang | 2012 | Journal of Integrative Agriculture2012，11，9： | 6 |
| 11 | Effect of platinum on the photocatalytic degradation of chlorinated organic compound显示文摘TiO 2 nanoparticles, doped with different Pt contents, were prepared by a modified photodeposition method using Degussa P-25 TiO 2 , H 2 PtCl 6 ·6H 2 O and methanol as the solvents. The physicochemical properties of Pt/TiO 2 were investigated by the nitrogen adsorption and desorption isotherm measurement technique, X-ray diffraction analysis and photoluminescence spectra, respectively. Reaction rates from photocatalytic removal of dichloromethane over Degussa P-25 TiO 2 and Pt/TiO 2 were evaluated. The average diameter and BET surface area of the TiO 2 catalyst particles were 300 nm and 50 m 2 /g, respectively. The degradation efficiency was 99.0%, 82.7%, 55.2%, and 57.9% with TiO 2 at inlet concentrations of 50, 100, 200, and 300 ppm, respectively. And the degradation efficiency was 99.3%, 79.7%, 76.5%, and 73.4% with a 0.005 wt.% Pt/TiO 2 at inlet concentrations of 50, 100, 200, and 300 ppm, respectively. In addition, we found that the photoluminescence emission peak intensities decreased with increases in the doping amount of Pt, which indicates that the irradiative recombination was weakened. Furthermore, the results showed that the UV/0.005 wt.% Pt/TiO 2 process was capable of efficiently decomposing gaseous DCM in air. | Chih Ming Ma Ya Wen Lee Gui Bing Hong Te Li Su Je Lueng Shie Chang Tang Chang | 2011 | Journal of Environmental Sciences2011，23，4： | 5 |
| 12 | Thioredoxin-Interacting Protein(TXNIP) Regulates Parkin/PINK1-mediated Mitophagy in Dopaminergic Neurons Under High-glucose Conditions: Implications for Molecular Links Between Parkinson’s Disease and Diabetes显示文摘Patients with diabetes mellitus have a higher risk of developing Parkinson’s disease(PD). However, the molecular links between PD and diabetes remain unclear.In this study, we investigated the roles of thioredoxininteracting protein(TXNIP) in Parkin/PINK1-mediated mitophagy in dopaminergic(DA) cells under high-glucose(HG) conditions. In streptozotocin-induced diabetic mice,TXNIP was upregulated and autophagy was inhibited in the midbrain, while the loss of DA neurons was accelerated by hyperglycemia. In cultured PC12 cells under HG, TXNIP expression was upregulated and the intracellular reactive oxygen species(ROS) levels increased, leading to cell death. Autophagic flux was further blocked and PINK1 expression was decreased under HG conditions. Parkin expression in the mitochondrial fraction and carbonyl cyanide 3-chlorophenylhydrazone(CCCP)-induced co-localization of COX IV(marker for mitochondria) and LAMP1(marker for lysosomes) were also significantly decreased by HG. Overexpression of TXNIP was sufficient to decrease the expression of both PINK1 and Parkin in PC12 cells, while knockdown of the expression of TXNIP by si RNA decreased intracellular ROS and attenuated cellular injury under HG. Moreover, inhibition of TXNIP improved the CCCP-induced co-localization of COX IV and LAMP1 in PC12 cells under HG. Together, these results suggest that TXNIP regulates Parkin/PINK1-mediated mitophagy under HG conditions, and targeting TXNIP may be a promising therapeutic strategy for reducing the risk of PD under hyperglycemic conditions. | Cun-Jin Su Zhu Shen Ru-Xiao Cui Ya Huang De-Lai Xu Feng-Lun Zhao Jie Pan Ai-Ming Shi Tong Liu Yun-Li Yu | 2020 | Neuroscience Bulletin2020，36，4： | 5 |

| 15 | 基于关联规则进行词对齐的跨领域情感分类算法(英文)显示文摘文本情感分类被应用于企业用户管理系统,通过自动对诸如评论、博客等带有情感倾向性文字进行分析,帮助商家更好地了解用户对商品或者服务的态度。然而,评论和博客等内容常源于不同应用领域,为每个领域训练一个能准确预测情感倾向的分类器非常困难。主要原因是,在不同领域,人们通常会用不同特征词表达相同情感,并且难以找到一个直接的映射函数,以建立不同领域特征词间的映射关系,从而消除领域间差异。因此,将某个领域训练好的分类器直接应用到另一个领域时,会因为领域间差异使得分类器准确率急速下降。本文提出一个新的基于关联规则进行特征词对齐的跨领域情感分类算法,该算法通过在同一领域中挖掘具有强关联关系的领域共享词和领域专有词词对,建立直接映射关系,并以领域共享词为桥梁,在不同领域的特征专有词之间建立间接映射关系,从而在一定程度上消除了源领域和目标领域之间的差异,有效提升了跨领域情感分类准确率。在亚马逊数据库上的实验结果证明该算法提高了跨领域情感分类性能。 | Xi-bin JIA Ya JIN Ning LI Xing SU Barry CARDIFF Bir BHANU | 2018 | Frontiers of Information Technology & Electronic Engineering2018，19，2： | 4 |
| 16 | Validation of the Simplified Chinese-character Version of the International Physical Activity Questionnaire-Long Form in Urban Community-dwelling Adults:a Cross-sectional Study in Hangzhou,China显示文摘Objective To assess the test-retest reliability and criterion validity of the Simplified Chinese-character version of the International Physical Activity Questionnaire Long form(IPAQ-L) in urban community-dwelling adults in Hanghzou,China.Methods A total of 158 eligible participants aged 25-59 years from 6 neighbourhoods in two central districts of Hangzhou completed the IPAQ-L questionnaire twice within a 7-day interval.Half of the subjects wore pedometers during the first 7 days.Test-retest reliability was examined by comparing the first(Day 1) and the second(Day 9) survey of IPAQ-L.Criterion validity was assessed by comparing IPAQ-L with pedometer data.Results Modest to good test-retest reliability was found with intraclass correlation coefficients of 0.67 for total PA,0.37 to 0.73 for specific dimensions,and 0.56 to 0.71 for different intensities of PA.Total PA measured by IPAQ-L was moderately correlated with exercise levels(partial r = 0.27,P = 0.020) and walking distance(partial r = 0.31,P = 0.007),which were measured by a pedometer,after adjusting for gender,age,educational attainment and employment status.Conclusion Our results indicate that the IPAQ-L is a reliable and validated measure for assessing physical activity levels in this population and possibly the adult population in other mainland Chinese cities. | REN Yan Jun SU Meng LIU Qing Min TAN Ya Yun DU Yu Kun LI Li Ming LYU Jun | 2017 | Biomedical and Environmental Sciences2017，30，4： | 4 |
| 17 | Bone Loss Induced by Simulated Microgravity,Ionizing Radiation and/or Ultradian Rhythms in the Hindlimbs of Rats显示文摘Objective To better understand the pathological causes of bone loss in a space environment, including microgravity, ionizing radiation, and ultradian rhythms. Methods Sprague Dawley(SD) rats were randomly divided into a baseline group, a control group, a hindlimb suspension group, a radiation group, a ultradian rhythms group and a combined-three-factor group. After four weeks of hindlimb suspension followed by X-ray exposure and/or ultradian rhythms, biomechanical properties, bone mineral density, histological analysis, microstructure parameters, and bone turnover markers were detected to evaluate bone loss in hindlimbs of rats. Results Simulated microgravity or combined-three factors treatment led to a significant decrease in the biomechanical properties of bones, reduction in bone mineral density, and deterioration of trabecular parameters. Ionizing radiation exposure also showed adverse impact while ultradian rhythms had no significant effect on these outcomes. Decrease in the concentration of the turnover markers bone alkaline phosphatase(b ALP), osteocalcin(OCN), and tartrate-resistant acid phosphatase-5 b(TRAP-5 b) in serum was in line with the changes in trabecular parameters. Conclusion Simulated microgravity is the main contributor of bone loss. Radiation also results in deleterious effects but ultradian rhythms has no significant effect. Combined-three factors treatment do not exacerbate bone loss when compared to simulated microgravity treatment alone. | ZHANG Ya Nan SHI Wen Gui LI He HUA Jun Rui FENG Xiu WEI Wen Jun WANG Ju Fang HE Jin Peng LEI Su Wen | 2018 | Biomedical and Environmental Sciences2018，31，2： | 4 |
| 18 | Dynamical decoupling of electron spins in phosphorus-doped silicon显示文摘Quantum coherence is an important enabling feature underpinning quantum computation. However, because of couplings with its noisy surrounding environment, qubits suffer from the decoherence effects. The dynamical decoupling (DD) technique uses pulse-induced qubit flips to effectively mitigate couplings between qubits and environment. Optimal DD eliminates dephasing up to a given order with the minimum number of pulses. In this paper, we first introduce our recent work on prolonging electron spin coherence in γ-irradiated malonic acid crystals and analyze different decoherence mechanisms in this solid system. Then we focus on electron spin relaxation properties in another system, phosphorous-doped silicon (Si:P) crystals. These properties have been investigated by pulse electron paramagnetic resonance (EPR). We also investigate the performance of the dynamical decoupling technique on this system. Using 8-pulse periodic DD, the coherence time can be extended to 296 μs compared with 112 μs with one-pulse control. | RONG Xing WANG Ya YANG JiaHui ZHU JinXian XU WanJie FENG PengBo WEN XuJie SU JiHu DU JiangFeng | 2011 | Chinese Science Bulletin2011，56，7： | 4 |
