| 1 | Cadmium accumulation and tolerance of two castor cultivars in relation to antioxidant systems显示文摘To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor(Ricinus communis L.) cultivars(Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment(0, 1 and 2 mg/L Cd) and a pot experiment using Cd-contaminated soil(34 mg/kg) with the addition of ethylenedinitrilotetraacetic acid(EDTA). The results indicated that there were significant differences between the two cultivars with respect to Cd uptake in shoots(113–248 mg/kg for Zibo No. 5 and 130–288 mg/kg Zibo No. 8), biomass tolerance indexes(64.9%–74.6% for Zibo No. 5 and 80.1%–90.9% for Zibo No. 8) in the hydroponic experiment and survival rates(0% for Zibo No. 5 and 100% for Zibo No. 8)determined by the addition of EDTA in the pot experiment, suggesting that Zibo No. 8 has higher tolerance than Zibo No. 5. Moreover, the castor cultivars have low bioconcentration factors(4.80% for Zibo No. 5 and 5.43% for Zibo No. 8) and low translocation factors(<1%).Consequently, Zibo No. 8 can participate in Cd phytostabilization in highly Cd-polluted areas. The results indicated that glutathione(GSH) as a non-enzymatic antioxidant, and antioxidant enzymes including superoxide dismutase(SOD), catalase(CAT) and guaiacol peroxidase(GPX), were cultivar- and dose-dependent. The higher tolerance of Zibo No. 8compared with Zibo No. 5 can be attributed to the higher GSH levels in the root and higher GPX activity in the leaf. | Hanzhi Zhang Qingjun Guo Junxing Yang Tongbin Chen Guangxu Zhu Marc Peters Rongfei Wei Liyan Tian Chunyu Wang Deyun Tan Jie Ma Gangming Wang Yingxin Wan | 2014 | Journal of Environmental Sciences2014，26，10： | 15 |
| 2 | Application of Pb isotopic tracing technique to constraining the source of Pb in the West Lake Longjing tea显示文摘This paper dealt with the Pb contents and Pb isotopic composition of the West Lake Longjing tea. The results showed that in the tea leaves, from young leaf →old leaf →tea limb, the Pb contents tend to increase gradu-ally from 1.63 →4.84 →6.07×10-6, wich revealed that the Pb was accumulated gradually in the tea. After cleaned, the Pb contents of tea leaves were significantly reduced. This indicated that the deposits on the surface of tea leaves made a great contributuion to Pb contents. The survey results for soils in the relevant tea gardens showed that soil from the Longjing tea garden has higher Pb contents, with an average level of 49.6×10-6, two times those of common soils (24×10-6) in China. Results of the systematic analysis for tea, tea garden soil and the samples with the relevant background of the Pb isotopic composition displayed that the Pb isotopic ratio of tea is 206Pb/207Pb=1.164±0.005 (2σ). The ratio of 206Pb/207Pb for the soil gradually decreased from residue phase, soil dilute acid extract phase, and then to urban topsoil, i.e., 1.175 →1.171 →1.170. The 208Pb/(206Pb+207Pb) ratios also show a similar variation trend. 206Pb/207Pb ratios in the samples with the relevant background were: vehicle exhaust, 1.124; coal-combustion, 1.156; atmosphere, 1.168; and water, 1.166. Comparative studies have shown that Pb pollution is popular in the environ-mental media (soil, atmosphere, water) in Hangzhou. With the aggravation of Pb pollution, the Pb isotopic composi-tion gradually changed from the natural background (soil residues) to the direction of automobile exhaust. This phe-nomenon could illustrate that the pollution source was the vehicle exhaust, while the coal-combustion contributed little to environmental pollution in Hangzhou. The Pb of the Longjing tea came mostly from soluble phase Pb in the polluted soil. Moreover, secondary pollution was caused by vehicle exhaust. | LU Yuanfa YANG Hongmei MA Liyan CHEN Xiqing WANG Qunying | 2011 | Chinese Journal Of Geochemistry2011，30，4： | 13 |
| 3 | A critical review on the health promoting effects of mushrooms nutraceuticals显示文摘Extensive elucidations focusing on the efficient health promoting properties and high nutritional values of mushrooms have been expanded dynamically from the past few decades.Due to its high quality of proteins,polysaccharides,unsaturated fatty acids,mineral substances,triterpenes sterols and secondary metabolites,mushrooms have always been appreciated for their vital role in protecting and curing various health problems,such as immunodeficiency,cancer,inflammation,hypertension,hyperlipidemia,hypercholesterolemia and obesity.Moreover,investigations in recent years have revealed the correlations between the health-promoting benefits and gut microbiota regulating effects induced by the mushrooms intake.Researches on the immense role in the nutritional and health benefits displayed by mushrooms have become an emergent task to study.The present article overviewed and compiled the latest information correlated to the health benefits and underlying functional mechanisms of mushroom nutraceuticals,and concluded that the supplementation of mushrooms as a dietary composition could become a natural adjuvant for the prevention and treatment of several health diseases. | Gaoxing Ma Wenjian Yang Liyan Zhao Fei Pei Donglu Fang Qiuhui Hu | 2018 | Food Science and Human Wellness2018，7，2： | 10 |
| 4 | Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding. | Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang | 2020 | Science China(Life Sciences)2020，63，11： | 8 |

| 8 | Characterization of a Novel Anti-DR5 Monoclonal Antibody WD1 with the Potential to Induce Tumor Cell Apoptosis显示文摘TNF-related apoptosis-inducing ligand (TRAIL) is a TNF family member capable of inducing apoptosis. Death receptor 5 (DR 5) is a key receptor of TRAIL and plays an important role in TRAIL-induced apoptosis. To prepare monoclonal antibodies (mAbs) against DR5,cDNA encoding soluble DR5 (sDR5) was firstly amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) with specific primers,and then inserted into a prokaryotic expression vector pET-30a. The recombinant plasmid was expressed in Escherichia coli strain BL21 (DE3),and sDR5 was purified by nickel affinity chromatography. As an antigen,sDR5 was used to immunize mice. Hybridomas secreting antibodies against sDR5 were identified. One positive clone was selected to produce antibody,WD1. ELISA and immunofluorescence demonstrated that WD1 could bind recombinant sDR5 and membrane-bound DR5 (mDR5) on Jurkat and Molt-4 cells. ATPLite assays showed that Jurkat and Molt-4 cells were sensitive to the antibody in a dose dependent manner. The Annexin V/PI assays and Giemsa's staining both showed that WD1 could induce Jurkat cell apoptosis efficiently. Transient transfection of 293T cells and indirect immunofluorescence assay demonstrated that mAb (WD1) couldn't cross-react with DR4. Our findings indicated that the novel antibody,WD1 could act as a direct agonist,bind DR5 characteristically,and initiate efficient apoptotic signaling and tumor regression. Thus,WD1 would be a leading candidate for potential cancer therapeutics. | Jing Wang Zhou Lin Chunxia Qiao Ming Lv Ming Yu He Xiao Qingyang Wang Liyan Wang Jiannan Feng Beifen Shen Yuanfang Ma Yan Li | 2008 | Cellular & Molecular Immunology2008，5，1： | 4 |
| 9 | White blood cell count and the incidence of hyperuricemia:insights from a community-based study显示文摘Hyperuricemia(HUA)is a risk factor for chronic kidney disease(CKD).The relationship between HUA and white blood cell(WBC)count remains unknown.A sampling survey for CKD was conducted in Sanlin community in 2012 and 2014.CKD was defined as proteinuria in at least the microalbuminuric stage or an estimated GFR of 60 mL/(min·1.73 m2).HUA was defined as serum uric acid>420µmol/L in men and>360µmol/L in women.This study included 1024 participants.The prevalence of HUA was 17.77%.Patients with HUA were more likely to have higher levels of WBC count,which was positively associated with HUA prevalence.This association was also observed in participants without CKD,diabetes mellitus,hyperlipidemia,or obesity.Multivariate logistic regression analysis showed that WBC count was independently associated with the risk for HUA in male and female participants.Compared with participants without HUA,inflammatory factors such as high-sensitivity C-reactive protein,tumor necrosis factor-α,and interleukin 6 increased in participants with HUA.Hence,WBC count is positively associated with HUA,and this association is independent of conventional risk factors for CKD. | Jian Liu Pingyan Shen Xiaobo Ma Xialian Yu Liyan Ni Xu Hao Weiming Wang Nan Chen | 2019 | Frontiers of Medicine2019，13，6： | 3 |
| 10 | A study of peroxyacetyl nitrate at a rural site in Beijing based on continuous observations from 2015 to 2019 and the WRFChem model显示文摘Peroxyacetyl nitrate(PA N)is one of the most important photochemical pollutants and has aroused much concern in China in recent decades.However,few studies described the long-term variations in PAN in China.In this study,we continuously monitored the PAN,03 and NOx concentrations at a regional background site near Beijing from August 2015 to February 2019.Based on the observed concentrations and climate data,w e analyzed the seasonal PAN variations.The results revealed that the monthly mean PAN concentration ranged from 0.33-2.41 ppb,with an average value of 0.94 ppb.The PAN concentration exhibited a distinct seasonal variation,with high values in spring and low values in winter.After analyzing the corresponding meteorological data,we found that stronger ultraviolet(UV)radiation,a relatively longer lifetime and a higher background PAN concentration contributed to the high PAN concentrations in spring.In addition,with the utilization of the WRF-Chem(Weather Research and Forecasting with Chemistry)model,the cause of the extremely high PAN concentration in spring 2018 wa s determined.The model results demonstrated that an anomalously low pressure and the southwesterly winds in northern China might be the main causes of the increased PAN concentration in Beijing and its surrounding area in spring 2018. | Yulu Qiu Zhiqiang Ma Weili Lin Weijun Quan Weiwei Pu Yingruo Li Liyan Zhou Qingfeng Shi | 2020 | Frontiers of Environmental Science & Engineering2020，14，4： | 3 |

| 16 | Lactate anions participate in T cell cytokine production and function显示文摘After antigen stimulation, T cells preferentially increase aerobic glycolysis to meet the bioenergetic and biosynthetic demands of T cell activation, proliferation, and effector functions. Lactate, a by-product of glycolysis, has been reported to function as an important energy source and signaling molecule. Here, we found that lactate anions are involved in cytokine production in Tcells after TCR activation. During ex vivo T cell activation, the addition of excess sodium lactate(Na L) increased the production of cytokines(such as IFNγ/IL-2/TNFα) more than the addition of sodium chloride(NaCl). This enhanced cytokine production was dependent on TCR/CD3 activation but not CD28 activation. In vivo, Na L treatment inhibited tumour growth in subcutaneously transplanted tumour models in a T cell-dependent manner, which was consistent with increased T cell cytokine production in the Na L treatment group compared to the Na Cl treatment group. Furthermore, a mechanistic experiment showed that this enhanced cytokine production was regulated by GAPDH-mediated post-transcriptional regulation. Taken together, our findings indicate a new regulatory mechanism involved in glycolysis that promotes T cell function. | Jing Wen Shipeng Cheng Yaguang Zhang Ran Wang Jiefang Xu Zhiyang Ling Liyan Ma Xinghao Ai Bing Sun | 2021 | Science China(Life Sciences)2021，64，11： | 2 |
| 17 | N,P-codoped porous carbon derived from chitosan with hierarchical N-enriched structure and ultra-high specific surface Area toward high-performance supercapacitors显示文摘In this work,a facile'carbonization-activation'strategy is developed to synthesize N,P-codoped hierarchical porous carbon.Phosphoric acid is innovatively introduced during the hydrothermal process to achieve in-situ P doping as well as create abundant pores,and the employment of sodamide is of vital importance to simultaneously serve as activating agent and N-source to succeed a high-level N doping.Thus,the obtained samples exhibit a unique three-dimensional hierarchical structure with an ultra-high specific surface area(3646 m^(2)g^(-1))and ultra-high N-doping level(9.81 at.%).Computational analyses confirm that N,P co-doping and higher N content can enhance active sites and widen potential differences of carbon materials to improve their capacitance.The as-prepared carbon materials demonstrate superior electrochemical performances,such as an ultra-high capacitance of 586 Fg^(-1)at 1 Ag^(-1),a superior rate capability of 409 Fg^(-1)at 20 Ag^(-1),and excellent long-term stability of 97%capacitance retention after10,000 cycles in 6 M KOH.Moreover,an assembled symmetric supercapacitor delivers a high energy density of 28.1 Wh kg^(-1)at the power density of 450 W kg^(-1)in 1 M Na_(2)SO_(4),demonstrating a great potential for applications in supercapacitors. | Xipeng Xin Na Song Ruiming Jia Bingnan Wang Hongzhou Dong Shuai Ma Lina Sui Yingjie Chen Qian Zhang Lifeng Dong Liyan Yu | 2021 | Journal of Materials Science & Technology2021，，29： | 2 |
| 18 | Multi-vision Attention Networks for on-Line Red Jujube Grading显示文摘To solve the red jujube classification problem,this paper designs a convolutional neural network model with low computational cost and high classification accuracy.The architecture of the model is inspired by the multi-visual mechanism of the organism and Dense Net.To further improve our model,we add the attention mechanism of SE-Net.We also construct a dataset which contains 23,735 red jujube images captured by a jujube grading system.According to the appearance of the jujube and the characteristics of the grading system,the dataset is divided into four classes:invalid,rotten,wizened and normal.The numerical experiments show that the classification accuracy of our model reaches to 91.89%,which is comparable to Dense Net-121,Inception V3,Inception V4,and Inception-Res Net v2.Our model has real-time performance. | SUN Xiaoye MA Liyan LI Gongyan | 2019 | Chinese Journal of Electronics2019，28，6： | 2 |
