| 1 | Gene cloning and expression of cadherin in midgut of Helicoverpa armigera and its Cry1A binding region显示文摘Cadherins belong to one of the families of animal glycoproteins responsible for cal-cium-dependent cell-cell adhesion. Recent literatures showed that the cadherin-like in midgut of several insects served as the receptor of Bt toxin Cry1A and the variation of cadherin-like is re-lated to insect’s resistance to Cry1A. The full-length cDNA encoding cadherin-like of Helicoverpa armigera is cloned by degenerate PCR and RACE techniques and the gene was designated as BtR-harm, which is 5581 bp in full-length, encoding 1730 amino acid residues (BtR-harm was deposited in GenBank and the accession number is AF519180). Its predicted molecular weight and isoelectric point were 195.39 kDa and 4.23, respectively. The inferred amino acid sequence includes a signal sequence, 11 cadherin repeats, a membrane-proximal region, a transmem-brane region and a cytoplasmic region. Sequence analysis indicated that the deduced protein sequence was most similar to the cadherin-like from Heliothis virescens with 84.2% identity and highly similar to three other lepidopteran cadherin from Bombyx mori, Manduca sexta and Pectinophora gossypiella, with the sequence identities of 60.3.6%, 57.5% and 51.0%, respec-tively. The cDNA encoding cadherin gene was expressed successfully in E. coli and the recom-binant proteins can bind with Cry1Ac. Truncation analysis and binding experiment of BtR-harm revealed that the Cry1A binding region was a contiguous 244-amino acid sequence, which lo-cated between amino acid 1217 and 1461. Semi-quantitative RT-PCR analysis showed that BtR-harm was highly expressed in midgut of H. armigera, very low expressed in foregut and hindgut and was not expressed in other tissues. After H. armigera producing resistance to Cry1Ac, the expression quantity of BtR-harm significantly decreased in midgut of H. armigera. It is the first confirmation that BtR-harm can function as receptor of Cry1Ac in H. armigera and the binding region was located on a contiguous 244 amino acid sequence, suggesting that the de-crease of expression quantity of BtR-harm is one of the main reasons for H. armigera resistance to Cry1Ac. | WANG Guirong WU Kongming LIANG Gemei GUO Yuyuan | 2005 | Science China(Life Sciences)2005，48，4： | 17 |
| 2 | Cerebral small vessel disease or intracranial large vessel atherosclerosis may carry different risk for future strokes显示文摘Background The effect of cerebral small vessel disease(CSVD)and intracranial arterial stenosis(ICAS)on stroke outcomes remains unclear.Methods Data of 1045 patients with minor stroke or transient ischaemic attack(TIA)were obtained from 45 sites of the Clopidogrel in High-Risk Patients with Acute Non-disabling Cerebrovascular Events(CHANCE)trial.We assessed the associations of burdens of CSVD and ICAS with new strokes and bleeding events using multivariate Cox regression models and those with modified Rankin Scale(mRS)scores using ordinal logistic regression models.Results Among the 1045 patients,CSVD was present in 830 cases(79.4%)and ICAS in 460(44.0%).Patients with>1 ICAS segment showed the highest risk of new strokes(HR 2.03,95%CI 1.15 to 3.56,p=0.01).No association between CSVD and the occurrence of new strokes was found.The presence of severe CSVD(common OR(cOR)2.01,95%CI 1.40 to 2.89,p<0.001)and>1 ICAS segment(cOR 2.15,95%CI 1.57 to 2.93,p<0.001)was associated with higher mRS scores.Severe CSVD(HR 10.70,95%CI 1.16 to 99.04,p=0.04),but not ICAS,was associated with a higher risk of bleeding events.Six-point modified CSVD score improved the predictive power for bleeding events and disability.Interpretation CSVD is associated with more disability and bleeding events,and ICAS is associated with an increased risk of stroke and disability in patients with minor stroke and TIA at 3 months.CSVD and ICAS may represent different vascular pathologies and play distinct roles in stroke outcomes. | Huimin Chen Yuesong Pan Lixia Zong Jing Jing Xia Meng Yuyuan Xu Hongyi Yan Xingquan Zhao Liping Liu Hao Li S Claiborne Johnston Yongjun Wang Yilong Wang | 2020 | Stroke & Vascular Neurology2020，5，2： | 13 |
| 3 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders:executive summary and 2019 update of the management of high-risk population显示文摘Aim Cerebrovascular disease is the leading cause of death and disability in China,causing a huge burden among patients and their families.Hence,stroke prevention is critical,especially in the high-risk population.Here,we present the evidence-based guideline suitable for the Chinese population.Methods Literature search of PubMed and Cochrane library(from January 1964 to June 2019)was done.After thorough discussion among the writing group members,recommendations were listed and summarised.This guideline was reviewed and discussed by the fellow writing committees of the Chinese Stroke Association’s Stroke.Results This evidence-based guideline was written in three parts:controlling the risk factors of stroke,utilisation of antiplatelet agents and assessing the risks of first-ever stroke.All recommendations were listed along with the recommending classes and levels of evidence.Conclusions This guideline provides recommendations for primary prevention of cerebrovascular disease among high-risk population in China.Controlling related risk factors,appropriately using antiplatelet agents,assessing the risk of developing first-ever stroke should help reduce the rate of cerebrovascular disease in China. | Yilong Wang Shangrong Han Haiqiang Qin Huaguang Zheng Bin Jiang Yong Cao Yuan Gao Ling Guan Qian Jia Yong Jiang Yuming Jiao Shuya Li Yapeng Li Zixiao Li Wei Liu Xiaojuan Ru Dongling Sun Haixin Sun Penglian Wang Tingting Wang Lixia Zong Lei Guo Xuewei Xie Yuming Xu Yuyuan Xu Xiaomeng Yang Yingying Yang Mengyuan Zhou Wenzhi Wang Chinese Stroke Association Stroke Council Guideline Writing Committee | 2020 | Stroke & Vascular Neurology2020，5，3： | 11 |

At pH 11, upon visible light irradiation for 6 h in the presence of O2, Zn-TDTAPc-F was found to be highly effective for the degradation of phenol in aqueous solution, and the degradation rate of phenol was more than 95%. HPLC was used to confirm formic acid, fumaric acid and maleic acid as its main degradation products. | CHEN WenXing CHEN ShiLiang LüShenShui YAO YuYuan XU MinHong | 2007 | Science China Chemistry2007，50，3： | 8 |
| 5 | Contribution of atmospheric nitrogen deposition to diffuse pollution in a typical hilly red soil catchment in southern China显示文摘Atmospheric nitrogen(N) deposition is currently high and meanwhile diffuse N pollution is also serious in China. The correlation between N deposition and riverine N export and the contribution of N deposition to riverine N export were investigated in a typical hilly red soil catchment in southern China over a two-year period. N deposition was as high as 26.1 to55.8 kg N/(ha·yr) across different land uses in the studied catchment, while the riverine N exports ranged from 7.2 to 9.6 kg N/(ha·yr) in the forest sub-catchment and 27.4 to30.3 kg N/(ha·yr) in the agricultural sub-catchment. The correlations between both wet N deposition and riverine N export and precipitation were highly positive, and so were the correlations between NH4+-N or NO3--N wet deposition and riverine NH4+-N or NO3--N exports except for NH4+-N in the agricultural sub-catchment, indicating that N deposition contributed to riverine N export. The monthly export coefficients of atmospheric deposited N from land to river in the forest sub-catchment(with a mean of 14%) presented a significant positive correlation with precipitation, while the monthly contributions of atmospheric deposition to riverine N export(with a mean of 18.7% in the agricultural sub-catchment and a mean of 21.0% in the whole catchment) were significantly and negatively correlated with precipitation. The relatively high contribution of N deposition to diffuse N pollution in the catchment suggests that efforts should be done to control anthropogenic reactive N emissions to the atmosphere in hilly red soil regions in southern China. | Jianlin Shen Jieyun Liu Yong Li Yuyuan Li Yi Wang Xuejun Liu Jinshui Wu | 2014 | Journal of Environmental Sciences2014，26，9： | 7 |
| 6 | Cloning,expression and binding specificity analysis of odorant binding protein 3 of the lucerne plant bug,Adelphocoris lineolatus(Goeze)显示文摘Credible evidence shows that odorant binding proteins(OBPs)are required for insect olfaction perception and play a key role in transporting hydrophobic odorants across the sensillum lymph to the olfactory receptors(ORs).In the present study,a novel OBP(AlinOBP3)gene from the lucerne plant bug,Adelphocoris lineolatus,was cloned and expressed.The expression pattern of AlinOBP3 was evaluated by qPCR,which indicated that AlinOBP3 was dominantly expressed in antennae.The binding properties of AlinOBP3 with 9 cotton volatiles and 5 sex pheromone analogs were measured by fluorescence competitive binding assays with the fluorescence probe 1-NPN.The results revealed that of 9 cotton volatiles,Myrcene,β-Ocimene and α-Phellandrene can bind with AlinOBP3.α-Phellandrene especially bound to AlinOBP3 with a high binding affinity,with a dissociation constant of 56.68 μmol/L.Of the 5 sex pheromone analogs,Hexyl butyrate had the strongest binding affinity with AlinOBP3,with a dissociation constant as 59.53 μmol/L.Butyl butyrate,trans-2-Hexenyl butyrate and Ethyl butyrate had medium binding affinities with AlinOBP3,with dissociation constants of 227.39,108.77 and 143.47 μmol/L,respectively.The results suggest that AlinOBP3 might be a pheromone binding protein(PBP)with a dual-function for the perception of sex pheromones and plant volatiles. | GU ShaoHua SUN Yang REN LiYan ZHANG XueYing ZHANG YongJun WU KongMing GUO YuYuan | 2010 | Chinese Science Bulletin2010，55，34： | 7 |
| 7 | Novel Ag nanocrystals based dental resin composites with enhanced mechanical and antibacterial properties显示文摘The aim of this work was to investigate the effect of trace addition of oleic acid coated Ag nanocrystals(Ag NCs) on mechanical and antibacterial properties of dental resin composites.Composites(70 wt%of silica loading) with 25 ppm,50 ppm,75 ppm and 100 ppm(wt) Ag NCs were prepared and the composite without Ag NCs served as a control.The experimental results showed that the addition of Ag NCs significantly improved the strength and modulus of the resin composite without compromising the shade.For the composite with 50 ppm Ag NCs,fiexural strength(140.3 MPa),modulus(13.2 GPa)and compressive strength(347.2 MPa) were increased by 4.1%,22.2%,13.3%,respectively,compared with the control.The antibacterial test demonstrated that trace Ag NCs provided the resin composites with an antibacterial effect.Such strong and antibacterial dental resin composites might be advantageous to prevent secondary caries and be potential for future clinical applications. | Fengwei Liu Ruili Wang Yuyuan Shi Xiaoze Jiang Bin Sun Meifang Zhu | 2013 | Progress in Natural Science:Materials International2013，23，6： | 5 |

| 9 | Preparation and photoactivity of thermosensitive polymer supported metallophthalocyanine显示文摘A novel reactive metallophthalocyanine derivative,zinc tetra(2,4-dichloro-1,3,5-triazine)aminophthalo-cyanine(Zn-TDTAPc),was prepared and immobilized on poly(N-isopropylacrylamide)(PNIPAAm) by covalent bonding to obtain a thermosensitive polymer(Zn-TDTAPc-g-PNIPAAm).Compared with zinc tetraaminophthalocyanine(Zn-TAPc),Zn-TDTAPc-g-PNIPAAm exhibits excellent solubility in water and in most organic solvents.Furthermore,it has a special thermosensitive property in water and the lower critical solution temperature(LCST) is 34.1℃.It was found that both dissolved and precipitated Zn-TDTAPc-g-PNIPAAm present high photoactivity evidenced by the experiment of photocatalytic degra-dation of 1,3-diphenylisobenzofuran(DPBF) in the presence of Zn-TDTAPc-g-PNIPAAm.These proper-ties suggest that it can be used potentially in photodynamic therapy(PDT). | CHEN WenXing LIU Fan LU WangYang SHEN XiaoYuan YAO YuYuan XU MinHong | 2008 | Science China Chemistry2008，51，6： | 5 |
| 10 | Rice metabolic regulatory network spanning the entire life cycle显示文摘As one of the most important crops in the world,rice(Oryza sativa)is a model plant for metabolome research.Although many studies have focused on the analysis of specific tissues,the changes in metab-olite abundance across the entire life cycle have not yet been determined.In this study,combining both tar-geted and nontargeted metabolite profiling methods,a total of 825 annotated metabolites were quantified in rice samples from different tissues covering the entire life cycle.The contents of metabolites in different tissues of rice were significantly different,with various metabolites accumulating in the plumule and radicle during seed germination.Combining these data with transcriptome data obtained from the same time period,we constructed the Rice Metabolic Regulation Network.The metabolites and co-expressed genes were further divided into 12 clusters according to their accumulation patterns,with members within each cluster displaying a uniform and clear pattern of abundance across development.Using this dataset,we established a comprehensive metabolic profile of the rice life cycle and used two independent strategies to identify novel transcription factors-namely the use of known regulatory genes as bait to screen for new networks underlying lignin metabolism and the unbiased identification of new glycerophospholipid metabolism regulators on the basis of tissue specificity.This study thus demonstrates how guilt-by-association analysis of metabolome and transcriptome data spanning the entire life cycle in cereal crops provides novel resources and tools to aid in understanding the mechanisms underlying important agro-nomic traits. | Chenkun Yang Shuangqian Shen Shen Zhou Yufei Li Yuyuan Mao Junjie Zhou Yuheng Shi Longxu An Qianqian Zhou Wenju Peng Yuanyuan Lyu Xuemei Liu Wei Chen Shouchuang Wang Lianghuan Qu Xianqing Liu Alisdair R.Fernie Jie Luo | 2022 | Molecular Plant2022，15，2： | 3 |
| 11 | Impact of Different Diets on Adult Tri-Spine Horseshoe Crab,Tachypleus tridentatus显示文摘Effective culture and management of adult tri-spine horseshoe crab,Tachypleus tridentatus can ensure that stock enhancement programs and aquaculture systems are maintained.To explore suitable feed for animals during the breeding season,Pacific oyster(Ostrea gigas)(oyster group;OG)and frozen sharpbelly fish(Hemiculter leucisculus)(frozen fish group;FG)were selected to feed 20 T.tridentatus male and female pairs,respectively.At the end of the experiment,intestinal samples were obtained to measure digestive enzymes activities.The intestinal flora were determined by 16S r DNA sequencing.No eggs were observed in the FG and one T.tridentatus adult died.No animals died in the OG,and 9.7×10;eggs were obtained.These results show that oysters are more suitable for the development and reproduction of adult T.tridentatus than frozen fish.Additionally,the digestive enzyme activity analysis revealed that animals in the OG exhibited higher protein digestibility than those in the FG,but no significant differences in lipid and carbohydrate uptake were observed between the groups.Furthermore,the intestinal flora analysis showed that operational taxonomic units(OTUs)and the Chao1 index were significantly higher in the OG than in the FG,but no significant difference was observed in the Shannon or Simpson indices between the groups.Our data indicate that the oyster diet improved the intestinal microbial diversity of T.tridentatus.We hypothesize that nutrients,such as oyster-based taurine,proteins,and highly unsaturated fatty acids,improve protease activity in the T.tridentatus digestive tract,alter the intestinal floral structure,and improve the reproductive performance of T.tridentatus. | YING Ziwei BAO Yuyuan LI Yinkang YE Guoling ZHANG Shuhuan XU Peng ZHU Junhua XIE Xiaoyong | 2022 | Journal of Ocean University of China2022，21，3： | 3 |

| 13 | Modification of Cellulose by Hydrophobic Long-chain Molecules: Advances and Prospects显示文摘Cellulose,a natural polymer material with abundant natural sources,is non-toxic,renewable,and biodegradable,making it one of the most promising green materials.Its inherent hydrophilicity dramatically limits the development and application of cellulose products.Hydrophobic modification can significantly change cellulose properties and endow it with additional functions depending on the types of modifying molecules.Controlled modification of cellulose by long-chain hydrophobic molecules is challenging.Significant advances took advantage of new reaction systems and copolymerization.This paper reviews recent innovations in long-chain cellulose hydrophobic modification.A brief value-adding assessment provides a reference for green changes of cellulose to make it fit for future applications. | Yuyuan Wang Haishan Zhang Leyi Lin Rui Wu Xiaohui Wang Junli Ren Chuanfu Liu Xiaoying Wang | 2020 | Paper And Biomaterials2020，5，3： | 3 |
| 14 | Enhanced electrocatalytic oxidation of dyes in aqueous solution using cobalt phthalocyanine modified activated carbon fiber anode显示文摘Cobalt tetra(2,4-dichloro-1,3,5-triazine)aminophthalocyanine(CoPc)was immobilized covalently on activated carbon fiber(ACF)felt to obtain CoPc-modified ACF(CoPc-ACF)catalyst,and an electrocatalytic oxidation system using CoPc-ACF as the anode was constructed.The electrocatalytic oxidation of Acid Red 1(AR1)was investigated in aqueous solution by an UV-vis spectrophotometer and UPLC.The results indicated that AR1 could be eliminated efficiently in this electrocatalytic oxidation system.In addition,the results of FTIR,TOC and GC-MS suggested that the electrocatalytic oxidation experienced the decoloration achieved by destroying the azo linkage and the further mineralization due to the cleavages of benzene ring and naphthalene ring.The intermediates were mainly small molecular compounds such as maleic acid and succinic acid,etc.Repetitive tests showed that CoPc-ACF can maintain high electrocatalytic activity over several cycles.The further EPR spin-trap experiments indicated that the hydroxyl radicals did not dominate the reaction in this electrocatalytic system,which was completely different from the traditional electro-Fenton system.Based on the non-radical reaction mechanism,the CoPc-modified ACF electrocatalyst has potential application in treating actual dyestuffs wastewaters,which are accompanied with high concentration of hydroxyl radical scavengers such as chlorine ions and additives in the textile printing and dyeing industry. | LI Nan DONG SuSu LV WangYang HUANG SanQing CHEN HaiXiang YAO YuYuan CHEN WenXing | 2013 | Science China Chemistry2013，56，12： | 2 |
| 15 | Study on catalytic oxidation of planar binuclear copper phthalocyanine on 2-mercaptoethanol显示文摘Mononuclear copper phthalocyanine (CuPc) and binuclear copper phthalocyanine (Cu2Pc2) were synthesized by the phenylanhydride-urea route, and their catalytic oxidation activity on 2-mercaptoethanol was studied. Based on the experimental results, a catalytic mechanism of Cu2Pc2 on 2-mercaptoethanol has been proposed. Furthermore, the effects of pH, Cu2Pc2 concentration, and temperature on the catalytic oxidation activity were evaluated. The results showed that CuPc has no catalytic activity, while Cu2Pc2 has high catalytic oxidation activity towards 2-mercaptoethanol with the optimal activity at pH 11. The reaction can further be enhanced by increasing Cu2Pc2 concentration and temperature, due to its endothermic characteristics. | CHEN Wenxing, WEI Lili, WANG Jinqian, YAO Yuyuan, Lü Shenshui & CHEN Shiliang Key Laboratory of Advanced Textile Materials and Manufacturing Technology, Ministry of Education, Zhejiang Sci-Tech Univer- sity, Hangzhou 310018, China | 2006 | Science China Chemistry2006，49，6： | 2 |
| 16 | Glucose metabolism controls humanγδ-cell-mediated tumor immunosurveillance in diabetes显示文摘Patients with type 2 diabetes mellitus(T2DM)have an increased risk of cancer.The effect of glucose metabolism onγδT cells and their impact on tumor surveillance remain unknown.Here,we showed that high glucose induced Warburg effect type of bioenergetic profle in Vy9vδ2 T cells,leading to excessive lactate accumulation,which further inhibited lytic granule secretion by impairing the traffcking of cytolytic machinery to the Vy9vδ2 T-cell-tumor synapse by suppressing AMPK activation and resulted in the loss of antitumor activity in vitro,in vivo and in patients.Strikingly,activating the AMPK pathway through glucose control or metformin treatment reversed the metabolic abnormalities and restored the antitumor activity of Vy9vδ2 T cells.These results suggest that the impaired antitumor activity of Vy9vδ2 T cells induced by dysregulated glucose metabolism may contribute to the increased cancer risk in T2DM patients and that metabolic reprogramming by targeting the AMPK pathway with metformin may improve tumor immunosurveillance. | Xiaofeng Mu Zheng Xiang Yan Xu Jing He Jianwen Lu Yuyuan Chen Xiwei Wang Chloe Ran Tu Yanme Wenyue Zhang Zhinan Yin Wing-hang Leung Yu-Lung Lau Yinping Liu Wenwei Tu | 2022 | Cellular & Molecular Immunology2022，19，8： | 2 |
| 17 | The bacterial abundance and production in the East China Sea: seasonal variations and relationships with the phytoplankton biomass and production显示文摘The East China Sea is a productive marginal sea with a wide continental shelf and plays an important role in absorbing atmospheric carbon dioxide and transferring terrigenous organic matter to the open ocean. To investigate the roles of heterotrophic bacteria in the biogeochemical dynamics in the East China Sea, bacterial biomasses(BB) and productions(BP) were measured in four cruises. The spatial distributions of the BB and the BP were highly season-dependent. Affected by the Changjiang River discharge, the BB and the BP were high in shelf waters(bottom depth not deeper than 50 m) and generally decreased offshore in August 2009. In December 2009 to January 2010, and November to December 2010, the BB and the BP were high in waters with medium bottom depth. The onshore-offshore decreasing trends of the BB and the BP also existed in May–June 2011, when the BB was significantly higher than in other cruises in shelf break waters(bottom depth deeper than 50 m but not deeper than 200 m). The results of generalized additive models(GAM) suggest that the BB increased with the temperature at a range of 8-20°C, increased with the chlorophyll concentration at a range of 0.02–3.00 mg/m3 and then declining, and decreased with the salinity from 28 to 35. The relationship between the temperature and the log-transformed bacterial specific growth rate(SGR) was linear. The estimated temperature coefficient(Q10) of the SGR was similar with that of the phytoplankton growth. The SGR also increased with the chlorophyll concentration. The ratio of the bacterial to phytoplankton production ranged from less than 0.01 to 0.40, being significantly higher in November–December 2010 than in May–June 2011. Calculated from the bacterial production and growth efficiency, the bacterial respiration consumed, on average, 59%, 72% and 23% of the primary production in August 2009, November–December 2010, and May–June 2011, respectively. | CHEN Bingzhang HUANG Bangqin XIE Yuyuan GUO Cui SONG Shuqun LI Hongbo LIU Hongbin | 2014 | Acta Oceanologica Sinica2014，33，9： | 2 |
