| 1 | ETCM v2.0:An update with comprehensive resource and rich annotations for traditional Chinese medicine显示文摘Existing traditional Chinese medicine(TCM)-related databases are still insufficient in data standardization,integrity and precision,and need to be updated urgently.Herein,an Encyclopedia of Traditional Chinese Medicine version 2.0(ETCM v2.0,http://gffzz3ff3e9d9e9f64aa3hpx6k6c5bkbk96xuv.ffgz.tsg.suse.edu.cn/ETCM2/front/#/)was constructed as the latest curated database hosting 48,442 TCM formulas recorded by ancient Chinese medical books,9872 Chinese patent drugs,2079 Chinese medicinal materials and 38,298 ingredients.To facilitate the mechanistic research and new drug discovery,we improved the target identification method based on a two-dimensional ligand similarity search module,which provides the confirmed and/or potential targets of each ingredient,as well as their binding activities.Importantly,five TCM formulas/Chinese patent drugs/herbs/ingredients with the highest Jaccard similarity scores to the submitted drugs are offered in ETCM v2.0,which may be of significance to identify prescriptions/herbs/ingredients with similar clinical efficacy,to summarize the rules of prescription use,and to find alternative drugs for endangered Chinese medicinal materials.Moreover,ETCM v2.0 provides an enhanced Java Script-based network visualization tool for creating,modifying and exploring multi-scale biological networks.ETCM v2.0 may be a major data warehouse for the quality marker identification of TCMs,the TCM-derived drug discovery and repurposing,and the pharmacological mechanism investigation of TCMs against various human diseases. | Yanqiong Zhang Xin Li Yulong Shi Tong Chen Zhijian Xu Ping Wang Meng Yu Wenjia Chen Bing Li Zhiwei Jing Hong Jiang Lu Fu Wenjing Gao Yanhua Jiang Xia Du Zipeng Gong Weiliang Zhu Hongjun Yang Haiyu Xu | 2023 | Acta Pharmaceutica Sinica B2023，13，6： | 3 |
| 2 | Regulation of the stability and ABA import activity of NRT1.2/NPF4.6 by CEPR2-mediated phosphorylation in Arabidopsis显示文摘Abscisic acid(ABA)transport plays an important role in systemic plant responses to environmental factors.However,it remains largely unclear about the precise regulation of ABA transporters in plants.In this study,we show that the C-terminally encoded peptide receptor 2(CEPR2)directly interacts with the ABA transporter NRT1.2/NPF4.6.Genetic and phenotypic analyses revealed that NRT1.2/NPF4.6 positively regulates ABA response and that NRT1.2/NPF4.6 is epistatically and negatively regulated by CEPR2.Further biochemical assays demonstrated that CEPR2 phosphorylates NRT1.2/NPF4.6 at serine 292 to promote its degradation under normal conditions.However,ABA treatment and non-phosphorylation at serine 292 prevented the degradation of NRT1.2/NPF4.6,indicating that ABA inhibits the phosphorylation of this residue.Transport assays in yeast and Xenopus oocytes revealed that non-phosphorylated NRT1.2/NPF4.6 had high levels of ABA import activity,whereas phosphorylated NRT1.2/NPF4.6 did not import ABA.Analyses of complemented nrt1.2 mutants that mimicked non-phosphorylated and phosphorylated NRT1.2/NPF4.6 confirmed that non-phosphorylated NRT1.2S292A had high stability and ABA import activity in planta.Additional experiments showed that NRT1.2/NPF4.6 was degraded via the 26S proteasome and vacuolar degradation pathways.Furthermore,we found that three E2 ubiquitin-conjugating enzymes,UBC32,UBC33,and UBC34,interact with NRT1.2/NPF4.6 in the endoplasmic reticulum and mediate its ubiquitination.NRT1.2/NPF4.6 is epistatically and negatively regulated by UBC32,UBC33,and UBC34 inplanta.Taken together,these results suggest that the stability and ABA import activity of NRT1.2/NPF4.6 are precisely regulated by its phosphorylation and degradation in response to environmental stress. | Lei Zhang Zipeng Yu Yang Xu Miao Yu Yue Ren Shizhong Zhang Guodong Yang Jinguang Huang Kang Yan Chengchao Zheng Changai Wu | 2021 | Molecular Plant2021，14，4： | 2 |
| 3 | Regulation of the stability and ABA import activity of NRT1.2/NPF4.6 by CEPR2-mediated phosphorylation in Arabidopsis显示文摘(Molecular Plant 14,633–646;April 52021)In Figure 1D in our original manuscript,we demonstrated by the mating-based split ubiquitin system(MbSUS)assay that the functional domains of CEPR2 interact with the loop region of NRT1.2/NPF4.6(NRT1.2loop,aa 232-346).However,the sub-image of-WLU in Figure 1D was mistakenly assembled. | Lei Zhang Zipeng Yu Yang Xu Miao Yu Yue Ren Shizhong Zhang Guodong Yang Jinguang Huang Kang Yan Chengchao Zheng Changai Wu | 2022 | Molecular Plant2022，15，10： | 1 |
| 4 | A Mixed-integer SDP Solution to Distributionally Robust Unit Commitment with Second Order Moment Constraints显示文摘A power system unit commitment(UC)problem considering uncertainties of renewable energy sources is investigated in this paper,through a distributionally robust optimization approach.We assume that the first and second order moments of stochastic parameters can be inferred from historical data,and then employed to model the set of probability distributions.The resulting problem is a two-stage distributionally robust unit commitment with second order moment constraints,and it can be recast as a mixed-integer semidefinite programming(MI-SDP)with finite constraints.The solution algorithm of the problem comprises solving a series of relaxed MI-SDPs and a subroutine of feasibility checking and vertex generation.Based on the verification of strong duality of the semidefinite programming(SDP)problems,we propose a cutting plane algorithm for solving the MI-SDPs;we also introduce an SDP relaxation for the feasibility checking problem,which is an intractable biconvex optimization.Experimental results on the IEEE 6-bus system are presented,showing that without any tuning of parameters,the real-time operation cost of distributionally robust UC method outperforms those of deterministic UC and two-stage robust UC methods in general,and our method also enjoys higher reliability of dispatch operation. | Xiaodong Zheng Haoyong Chen Yan Xu Zhengmao Li Zhenjia Lin Zipeng Liang | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 1 |
| 5 | Modified methods for isolation of pancreatic stellate cells from human and rodent pancreas显示文摘Primary cultures of pancreatic stellate cells(PSCs) remain an important basis for in vitro study.However,effective methods for isolating abundant PSCs are currently lacking.We report on a novel approach to isolating PSCs from normal rat pancreases and human pancreatic ductal adenocarcinoma(PDAC) tissue.After anaesthesia and laparotomy of the rat,a blunt cannula was inserted into the pancreatic duct through the anti-mesentery side of the duodenum,and the pancreas was slowly infused with an enzyme solution until all lobules were fully dispersed.The pancreas was then pre-incubated,finely minced and incubated to procure a cell suspension.PSCs were obtained after the cell suspension was filtered,washed and subject to gradient centrifugation with Nycodenz solution.Fresh human PDAC tissue was finely minced into 1×1×l mm^3 cubes with sharp blades.Tissue blocks were placed at the bottom of a culture plate with fresh plasma(EDTA-anti-coagulated plasma from the same patient,mixed with CaCL) sprinkled around the sample.After culture for 5-10 days under appropriate conditions,activated PSCs were harvested.An intraductal perfusion of an enzyme solution simplified the procedure of isolation of rat PSCs,as compared with the multiple injections technique,and a modified outgrowth method significantly shortened the outgrowth time of the activated cells.Our modification in PSC isolation methods significantly increased the isolation efficiency and shortened the culture period,thus facilitating future PSC-related research. | Liangtao Zhao Baobao Cai Zipeng Lu Lei Tian Song Guo Pengfei Wu Dong Qian Qingcheng Xu Kuirong Jiang Yi Miao | 2016 | The Journal of Biomedical Research2016，30，6： | 1 |
| 6 | The Brassicaceae-specific secreted peptides,STMPs,function in plant growth and pathogen defense显示文摘Low molecular weight secreted peptides have recently been shown to affect multiple aspects of plant growth,development,and defense responses.Here,we performed stepwise BLAST filtering to identify unannotated peptides from the Arabidopsis thaliana protein database and uncovered a novel secreted peptide family,secreted transmembrane peptides(STMPs).These low molecular weight peptides,which consist of an N-terminal signal peptide and a transmembrane domain,were primarily localized to extracellular compartments but were also detected in the endomembrane system of the secretory pathway,including the endoplasmic reticulum and Golgi.Comprehensive bioinformatics analysis identified 10 STMP family members that are specific to the Brassicaceae family.Brassicaceae plants showed dramatically inhibited root growth uponexposure to chemically synthesized STMP1 and STMP2.Arabidopsis overexpressing STMP1,2,4,6,or 10 exhibited severely arrested growth,suggesting that STMPs are involved in regulating plant growth and development.In addition,in vitro bioassays demonstrated that STMP1,STMP2,and STMP10 have antibacterial effects against Pseudomonas syringae pv.tomato DC3000,Ralstonia solanacearum,Bacillus subtilis,and Agrobacterium tumefaciens,demonstrating that STMPs are antimicrobial peptides.These findings suggest that STMP family members play important roles in various developmental events and pathogen defense responses in Brassicaceae plants. | Zipeng Yu Yang Xu Lifei Zhu Lei Zhang Lin Liu Di Zhang Dandan Li Changai Wu Jinguang Huang Guodong Yang Kang Yan Shizhong Zhang Chengchao Zheng | 2020 | Journal of Integrative Plant Biology2020，62，4： | 1 |
| 7 | Prediction and Verifcation of Forming Limit Diagrams Based on a Modifed Shear Failure Criterion显示文摘The forming limit diagram plays an important role in predicting the forming limit of sheet metals.Previous studies have shown that,the method to construct the forming limit diagram based on instability theory of the original shear failure criterion is efective and simple.The original shear instability criterion can accurately predict the left area of the forming limit diagram but not the right area.In this study,in order to improve the accuracy of the original shear failure criterion,a modifed shear failure criterion was proposed based on in-depth analysis of the original shear failure criterion.The detailed improvement strategies of the shear failure criterion and the complete calculation process are given.Based on the modifed shear failure criterion and diferent constitutive equations,the theoretical forming limit of TRIP780 steel and 5754O aluminum alloy sheet metals are calculated.By comparing the theoretical and experimental results,it is shown that proposed modifed shear failure criterion can predict the right area of forming limit more reasonably than the original shear failure criterion.The efect of the pre-strain and constitutive equation on the forming limits are also analyzed in depth.The modifed shear failure criterion proposed in this study provides an alternative and reliable method to predict forming limit of sheet metals. | Haibo Wang Zipeng Wang Yu Yan Yuanhui Xu | 2023 | Chinese Journal of Mechanical Engineering2023，36，5： | 0 |
| 8 | Stress compensation based on interfacial nanostructures for stable perovskite solar cells显示文摘The long-term stability issue of halide perovskite solar cells hinders their commercialization.The residual stress-strain affects device stability,which is derived from the mismatched thermophysical and mechanical properties between adjacent layers.In this work,we introduced the Rb_(2)CO_(3)layer at the interface of SnO_(2)/perovskite with the hierarchy morphology of snowflake-like microislands and dendritic nanostructures.With a suitable thermal expansion coefficient,the Rb_(2)CO_(3)layer benefits the interfacial stress relaxation and results in a compressive stress-strain in the perovskite layer.Moreover,reduced nonradiative recombination losses and optimized band alignment were achieved.An enhancement of open-circuit voltage from 1.087 to 1.153 V in the resultant device was witnessed,which led to power conversion efficiency(PCE)of 22.7%(active area of 0.08313 cm^(2))and 20.6%(1 cm2).Moreover,these devices retained 95%of its initial PCE under the maximum power point tracking(MPPT)after 2700 h.It suggests inorganic materials with high thermal expansion coefficients and specific nanostructures are promising candidates to optimize interfacial mechanics,which improves the operational stability of perovskite cells. | Cheng Zhu Xi Wang Hangxuan Li Chenyue Wang Ziyan Gao Pengxiang Zhang Xiuxiu Niu Nengxu Li Zipeng Xu Zhenhuang Su Yihua Chen Huachao Zai Haipeng Xie Yizhou Zhao Ning Yang Guilin Liu Xueyun Wang Huanping Zhou Jiawang Hong Xingyu Gao Yang Bai Qi Chen | 2023 | Interdisciplinary Materials2023，2，2： | 0 |
| 9 | The Super-large Ensemble Experiments of CAS FGOALS-g3显示文摘A super-large ensemble simulation dataset with 110 members has been produced by the fully coupled model FGOALS-g3 developed by researchers at the Institute of Atmospheric Physics,Chinese Academy of Sciences.This is the first dataset of large ensemble simulations with a climate system model developed by a Chinese modeling center.The simulation has the largest realizations up to now worldwide in terms of single-model initial-condition large ensembles.Each member includes a historical experiment(1850-2014)and an experiment(2015-99)under the very high greenhouse gas emissions Shared Socioeconomic Pathway scenario(SSP5-8.5).The dataset includes monthly and daily temperature,precipitation,and other variables,requiring storage of 275 TB.Additionally,the surface air temperature(SAT)and land precipitation simulated by the FGOALS-g3 super-large ensemble have been validated and projected.The ensemble can capture the response of SAT and land precipitation to external forcings well,and the internal variabilities can be quantified.The availability of more than 100 realizations will help researchers to study rare events and improve the understanding of the impact of internal variability on forced climate changes. | Pengfei LIN Bowen ZHAO Jilin WEI Hailong LIU Wenxia ZHANG Xiaolong CHEN Jie JIANG Mengrong DING Wenmin MAN Jinrong JIANG Xu ZHANG Yuewen DING Wenrong BAI Chenyang JIN Zipeng YU Yiwen LI Weipeng ZHENG Tianjun ZHOU | 2022 | Advances in Atmospheric Sciences2022，39，10： | 0 |
| 10 | Stability of dimensionally stable anode for chlorine evolution reaction显示文摘Chlorine(Cl2)is one of the most important chemicals produced by the electrolysis of brine solutions and is a key raw material for many areas of industrial chemistry.For nearly half a century,dimensionally stable anode(DSA)made from a mixture of RuO_(2) and TiO_(2) solid oxides coated on Ti substrate has been the most widely used electrode for chlorine evolution reaction(CER).In harsh operating environments,the stability of DSAs remains a major challenge greatly affecting their lifetime.The deactivation of DSAs significantly increases the cost of the chlor-alkali industry due to the corrosion of Ru and the formation of the passivation layer TiO_(2).Therefore,it is urgent to develop catalysts with higher activity and stability,which requires a thorough understanding of the deactivation mechanism of DSA catalysts.This paper reviews existing references on the deactivation mechanisms of DSA catalysts,including both experimental and theoretical studies.Studies on how CER selectivity affects electrode stability are also discussed.Furthermore,studies on the effects of the preparation process,elemental composition,and surface/interface structures on the DSA stability and corresponding improvement strategies are summarized.The development of other non-DSA-type catalysts with comparable stability is also reviewed,and future opportunities in this exciting field are also outlined. | Ziliang Deng Shuying Xu Chuhao Liu Xueqiang Zhang Mufan Li Zipeng Zhao | 2024 | Nano Research2024，17，3： | 0 |
| 11 | Function identification of Md TIR1 in apple root growth benefited from the predicted Md PPI network显示文摘Protein–protein interaction(PPI)network analysis is an effective method to identify key proteins during plant development,especially in species for which basic molecular research is lacking,such as apple(Malus domestica).Here,an MdPPI network containing 30806 PPIs was inferred in apple and its quality and reliability were rigorously verified.Subsequently,a rootgrowth subnetwork was extracted to screen for critical proteins in root growth.Because hormone-related proteins occupied the largest proportion of critical proteins,a hormonerelated sub-subnetwork was further extracted from the root-growth subnetwork.Among these proteins,auxin-related M.domestica TRANSPORT INHIBITOR RESISTANT 1(MdTIR1)served as the central,high-degree node,implying that this protein exerts essential roles in root growth.Furthermore,transgenic apple roots overexpressing an MdTIR1 transgene displayed increased primary root elongation.Expression analysis showed that MdTIR1 significantly upregulated auxin-responsive genes in apple roots,indicating that it mediates root growth in an auxin-dependent manner.Further experimental validation revealed that MdTIR1 interacted with and accelerated the degradation of MdIAA28,MdIAA43,andMdIAA46.Thus,MdTIR1-mediated degradation of MdIAAs is critical in auxin signal transduction and root growth regulation in apple.Moreover,our network analysis and high-degree node screening provide a novel research technique for more generally characterizing molecular mechanisms. | Lin Liu Zipeng Yu Yang Xu Cheng Guo Lei Zhang Changai Wu Guodong Yang Jinguang Huang Kang Yan Huairui Shu Chengchao Zheng Shizhong Zhang | 2021 | Journal of Integrative Plant Biology2021，63，4： | 0 |
| 12 | Digestive tract reconstruction in pancreaticoduodenectomy in University Hospitals of China: a national questionnaire survey显示文摘Background Pancreaticoduodenectomy(PD)has been widely applied in general hospitals in China;however,there is still a lack of unified standards for each surgical technique and procedure.This survey is intended to investigate the current status of digestive tract reconstruction after PD in university hospitals in China.Method A cross-sectional survey was conducted among the members of the Young Elite Pancreatic Surgery Club of China by using the Questionnaire for Digestive Tract Reconstruction after Pancreaticoduodenectomy.The questionnaire was disseminated and collected by point-to-point communication via WeChat public platforms.Results A total of 73 valid questionnaires were returned from 65 university hospitals in 28 provincial divisions of China's Mainland.The respondents who performed PD surgery with an annual volume of over 100 cases accounted for 63%.Generally,laparoscopic PD was performed less often than open PD.Child and Whipple reconstructions accounted for 70%and 26%,respectively.The sequence of pancreatoenteric,biliary-enteric,and gastrointestinal reconstruction accounted for 84%of cases.In pancreatoenteric anastomosis,double-layer anastomosis is the most commonly employed type,accounting for approximately 67%,while single-layer anastomosis accounts for 30%.Of the double-layer anastomoses,duct-to-mucosa/dunking(94%/4%)PJ was performed with duct-mucosa using the Blumgart method(39%)and Cattel-Warren(29%),with continuous/interrupted sutures in the inner layer(69%/31%)and continuous/interrupted sutures in the outer layer(53%/23%).In single-layer anastomosis,continuous/interrupted sutures accounted for 41%/45%.In hepatojejunostomy,single-layer/double-layer suture accounted for 79%/4%,and continuous/interrupted suture accounted for 75%/9%.Forty-six percent of the responding units had not applied double-layer biliary-intestinal anastomosis in the last 3 years,75%of the responding surgeons chose the anastomosis method according to bile duct diameter,with absorbable/non-absorbable suture accounting for 86%/12%.PD/pylorus-preserving PD accounted for 79%/11%of GJ cases,the distance between GJ and HJ<30 cm,30-50 cm and>50 cm were 11%,75%,and 14%,respectively.Antecolic/retrocolic GJ accounted for 71%/23%of cases.Twenty-two percent of GJ cases employed Braun anastomosis,while 55%and 19%of GJ cases used linear cutting staplers/tube-type staplers,respectively;60%/14%were reinforced/not reinforced via manual suturing after stapler anastomosis.Manual anastomosis in GJ surgery employed absorbable/non-absorbable sutures(91%/9%).Significant differences in reconstruction techniques were detected between different volumes of PD procedures(<100/year and>100/year),regions with different economic development levels,and between north and south China.Conclusion Digestive tract reconstruction following PD exists heterogeneity in Chinese university hospitals.Corresponding prospective clinical studies are needed to determine the consensus on pancreatic surgery that meets the clinical reality in China. | Jishu Wei Qiang Xu Yuhua Zhang Jiabin Jin Xiaodong Tian Qiaofei Liu Zipeng Lu Zheng Wang Shanmiao Gou Song Gao Xianlin Han Yefei Rong Niandong Ji Ye Lin Guolin Li Shi Chen Feng Cao Hua Chen Wenming Wu Yupei Zhao the Young Elite Pancreatic Surgery Club of China | 2022 | Journal of Pancreatology2022，5，3： | 0 |
| 13 | Energy Optimization in Multi-UAV-Assisted Edge Data Collection System显示文摘In the IoT(Internet of Things)system,the introduction of UAV(Unmanned Aerial Vehicle)as a new data collection platform can solve the problem that IoT devices are unable to transmit data over long distances due to the limitation of their battery energy.However,the unreasonable distribution of UAVs will still lead to the problem of the high total energy consumption of the system.In this work,to deal with the problem,a deployment model of a mobile edge computing(MEC)system based on multi-UAV is proposed.The goal of the model is to minimize the energy consumption of the system in the process of data transmission by optimizing the deployment of UAVs.The DEVIPSK(differential evolution algorithm with variable population size based on a mutation strategy pool initialized by K-Means)is proposed to solve the model.In DEVIPSK,the population is initialized by K-Means to obtain better initial positions of UAVs.Besides,considering the limitation of the fixed mutation strategy in the traditional evolutionary algorithm,a mutation strategy pool is used to update the positions of UAVs.The experimental results show the superiority of the DEVIPSK and provide guidance for the deployment of UAVs in the field of edge data collection in the IoT system. | Bin Xu Lu Zhang Zipeng Xu Yichuan Liu Jinming Chai Sichong Qin Yanfei Sun | 2021 | Computers, Materials & Continua2021，，11： | 0 |
| 14 | Selecting small molecule DNA aptamers with significant conformational changes for constructing transcriptional switches and biosensors显示文摘Small molecule aptamers discovered by traditional selection methods usually lack conformational changes upon target binding.This limits the use of aptamers as molecular probes for small molecule detection and regulatory elements of genetic circuits.Here,we report a new method called capture and in vitro transcription-systematic evolution of ligands by exponential enrichment(CIVT-SELEX)to select DNA aptamers that can not only bind to small molecule ligands but also undergo significant conformational changes.Through this method,we select a structure-switching aptamer of uridine-5′-diphosphate(UDP).Taking advantage of its conformational changes,we first construct a UDP-responsive transcriptional switch by inserting the aptamer in a genetic circuit and demonstrate that it can respond to the addition of UDP and regulate the transcription of downstream genes.We also build a UDP aptamer-based biosensor that can be used for active glycosyltransferase screening.We believe this method can provide a universal platform for selecting small molecule aptamers with conformational changes and expand the use of aptamers in small molecule detection and genetic regulation. | Shaobin Guo Jingjing Lin Lujie Lin Wen Xu Yan Guo Zipeng Xu Chunhua Lu Xianai Shi Lanlan Chen Huanghao Yang | 2023 | Science China Chemistry2023，66，5： | 0 |
| 15 | Glutathione S-Transferase(GST)Identified from Giant Kelp Macrocystis pyrifera Increases the Copper Tolerance of Synechococcus elongatus PCC 7942显示文摘The glutathione S-transferases gene family plays an important regulatory role in growth and development,and responses to environmental change.In this study,six complete GST genes(Mp GST1,Mp GST2,Mp GST3,MpGST4,Mp GST5,and Mp GST6)were cloned from the gametophytes of brown alga Macrocystis pyrifera.Subsequent bioinformatics analysis showed that these six genes encoded proteins with 202,216,288,201,205,and 201 aa,respectively.Moreover,Mp GST3 differs from the other GST genes.Phylogenetic analysis suggested that MpGST3 belongs to the Ure2p type GST.Domain analysis suggested that the other GSTs from M.pyrifera belong to the soluble GST family and form an independent branch with the GSTs found in the other macroalgae,suggesting that a new GST type was formed during macroalgal evolution.GST genes were upregulated in M.pyrifera when 2.5 mg L^(-1)Cu ions were added to the medium.Six GST genes were integrated into the genome of Synechococcus elongatus PCC 7942,and their functions were verified by measuring light absorbance,photosynthetic pigment content,and photosynthetic parameters of the transformed strains under 0.3 mg L^(-1)Cu ion stress.The results showed much higher levels of various parameters in the transformed strains than in the wild strain.The transformed strains(with the MpGST genes)showed significantly enhanced resistance to Cu ion stress,while the wild strain almost died.The results of this study lay a theoretical foundation for further research on the Cu ion stress resistance function of GSTs in M.pyrifera. | GU Zipeng REN Yudong LIANG Chengwei ZHANG Xiaowen GENG Yilin XU Dong YE Naihao | 2023 | Journal of Ocean University of China2023，22，3： | 0 |
