1An Investigation of Oxidative DNA Damage in Pharmacy Technicians Exposed to Antineoplastic Drugs in Two Chinese Hospitals Using The Urinary 8-OHdG Assay显示文摘Objective To investigate oxidative DNA damage in pharmacy technicians preparing antineoplastic drugs at the PIVAS (Pharmacy Intravenous Admixture Service) in two Chinese hospitals.Methods Urinary 8-OHdG served as a biomarker.5-Fluorouracil (5-FU) concentrations in air,masks and gloves were determined.The spill exposure of each PIVAS technician to antineoplastic drugs was investigated.Eighty subjects were divided into exposed group I,II,and control group I,II.Results 5-FU concentration ratios for gloves and masks in exposed group I were significantly higher than those in exposed group II (P<0.05 or P<0.01).The average urinary 8-OHdG concentrations in exposed group I,control group I,exposed group II,and control group II were 14.69±0.93,10.68±1.07,10.57±0.55,and 11.96±0.73 ng/mg Cr,respectively.Urinary 8-OHdG concentration in exposed group I was significantly higher than that in control group I or that in exposed group II (P<0.01).There was a significant correlation between urinary 8-OHdG concentrations and spill frequencies per technician (P<0.01).Conclusion There was detectable oxidative DNA damage in PIVAS technicians exposed to antineoplastic drugs.This oxidative DNA damage may be associated with their spill exposure experience and contamination of their personal protective equipment.HUANG Yu Wen JIAN Le ZHANG Mei Bian ZHOU Quan YAN Xiao Feng HUA Xu Dong ZHOU Ying HE Ji Liang 2012Biomedical and Environmental Sciences2012,25,1:30
2The recommendations of Chinese Parkinson’s disease and movement disorder society consensus on therapeutic management of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is a chronic,progressive and debilitating disease,which affects over 2.5 million people in China.PD is characterized clinically by resting tremor,muscular rigidity,bradykinesia and postural instability.As the disease progresses,additional complications can arise such as non-motor and neurobehavioral symptoms.Pharmacological treatment and surgical intervention for PD have been implemented in China.Until 10 years ago,there was lack of standardization for the management of PD in different regions and among different physicians,leading to different treatment levels in different regions and different physicians.Since then,the Chinese Parkinson’s Disease and Movement Disorder Society have published three versions of guidelines for the management of PD in China,in 2006,2009 and 2014,respectively.Correspondingly,the overall level of treatment for PD in China improved.Objectives:To update the treatment guidelines based on current foreign and domestic practice guidelines and clinical evidence,and to improve the treatment options available to physicians in the management of PD.Summary:A variety of treatment recommendations in the treatment guidelines have been proposed,including physical activity and disease-modifying medication,which should be initiated at the early-stage of the disease.The principles of dosage titration should be followed to avoid acute adverse reactions to the drugs,to achieve a satisfactory clinical effect with a low dose and to reduce the incidence of long-term motor complications.Moreover,different treatment strategies should be considered at different stages of the disease.Importantly,treatment guidelines and personalized treatments should be valued equally.A set of treatment recommendations has been developed to assist physicians to improve and optimize clinical outcomes for patients with PD in China.Shengdi Chen Piu Chan Shenggang Sun Haibo Chen Baorong Zhang Weidong Le Chunfeng Liu Guoguang Peng Beisha Tang Lijuan Wang Yan Cheng Ming Shao Zhenguo Liu Zhenfu Wang Xiaochun Chen Mingwei Wang Xinhua Wan Huifang Shang Yiming Liu Pingyi Xu Jian Wang Tao Feng Xianwen Chen Xingyue Hu Anmu Xie Qin Xiao 2016Translational Neurodegeneration2016,5,1:23
3Fuzzy Control of LED Tunnel Lighting and Energy Conservation显示文摘Current highway tunnel lighting control systems are often manually controlled,resulting in significant energy waste.This article designs a fuzzy control algorithm for tunnel lighting energy control systems.The system uses LED (Light Emitting Diode) lighting,so the fuzzy control algorithm is designed for LED lights.The traffic and the natural illumination level are used as parameters in the intelligent lighting control algorithm.This system has been deployed in the Lengshui tunnel on the 49th provincial highway of Zhejiang province and operated for more than six months.The performance results show that the energy conservation system provides sufficient lighting levels for traffic safety with significant energy conservation.Hong Zeng Jian Qiu Xingfa Shen Guojun Dai Peng Liu Shuping Le 2011Tsinghua Science and Technology2011,16,6:17
4Changes of Oxidative Stress and Soluble Sugar in Anthers Involve in Rice Pollen Abortion Under Drought Stress显示文摘Two rice maintaining lines with different drought tolerances, viz., Jin 23B (tolerant) and Zhenshan 97B (sensitive), were used to study the oxidative stress and soluble sugar in rice anthers and pollen viability under drought stress during flowering stage. Higher antioxidant enzyme activities and lower malonaldehyde (MDA) content in rice anthers were observed in Jin 23B than in Zhenshan 97B under drought stress. Further, a great increase in the content of soluble sugar in rice anthers of Jin 23B was observed across the whole drought exposure, while Zhenshan 97B showed significant decrease in soluble sugar during 9-12 d after drought stress (DADS). Accordingly, a marked decline of pollen fertility and activity, pollen numbers in an anther and pollen numbers on a stigma was observed in Zhenshan 97B, whereas little difference was found in Jin 23B. Thus, we suggest that pollen abortion caused by drought stress may be related with the reciprocity between oxidative stress and soluble sugar content in rice anthers.FU Guan-fu SONG Jian XIONG Jie LI Yu-rong CHEN Hui-zhe LE Ming-kai TAO Long-xing 2011Agricultural Sciences in China2011,10,7:12

6Efficient spectral regulation in Ce:Lu_(3)(Al,Cr)_(5)O_(12) and Ce:Lu_(3)(Al,Cr)_(5)O_(12)/Ce:Y_(3)Al_(5)O_(12) transparent ceramics with high color rendering index for high-power white LEDs/LDs显示文摘Realizing a high color rendering index(CRI)in Ce:LuAG transparent ceramics(TCs)with desired thermal stability is essential to their applications in white LEDs/LDs as color converters.In this study,based on the scheme of configuring the red component by Cr^(3+) doping,an efficient spectral regulation was realized in Ce,Cr:LuAG TCs.A unilateral shift phenomenon could be observed in both photoluminescence(PL)and photoluminescence excitation(PLE)spectra of TCs.By constructing TC-based white LED/LD devices in a remote excitation mode,luminescence properties of Ce,Cr:LuAG TCs were systematically investigated.The CRI values of Ce:LuAG TC based white LEDs could be increased by a magnitude of 46.2%.Particularly,by combining the as fabricated Ce,Cr:LuAG TCs with a 0.5 at% Ce:YAG TC,surprising CRI values of 88 and 85.5 were obtained in TC based white LEDs and LDs,respectively.Therefore,Ce,Cr:LuAG TC is a highly promising color convertor for high-power white LEDs/LDs applied in general lighting and displaying.Tianyuan ZHOU Chen HOU Le ZHANG Yuelong MA Jian KANG Tao LI Rui WANG Jin HUANG Junwei LI Haidong REN Zhenxiao FU Farida ASELIM Ming LI Hao CHEN 2021Journal of Advanced Ceramics2021,10,5:7
7A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (http://gffzzc750bc0108fa4044skf55vcfwfbok6cpp.ffgz.tsg.suse.edu.cn/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants.Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang 2018Molecular Plant2018,11,11:7
8Human movement monitoring and behavior recognition for intelligent sports using customizable and flexible triboelectric nanogenerator显示文摘Effective collection,recognition,and analysis of sports information is the key to intelligent sports,which can help athletes to improve their skills and formulate scientific training plans and competition strategies.At present,wearable electronic devices used for movement monitoring still have some limitations,such as high cost and energy consumption,incompatibility of suitable flexibility and personalized spatial structure,dissatisfactory data analysis methods,etc.In this work,a novel three-dimensionalprinted thermoplastic polyurethane is introduced as the elastic shell and friction layer,and it endows the proposed customizable and flexible triboelectric nanogenerator(CF-TENG)with personalized spatial structure and robust correlation to external pressure.In practical application,it exhibits highly sensitive responses to the joint-bending motion of the finger,wrist,or elbow.Furthermore,a pressure-sensing insole and smart ski pole based on CF-TENG are manufactured to build a comprehensive sports monitoring system to transmit the athletes’motion information from feet and hands through the plantar pressure distribution and ski pole action.To recognize the movement status,the self-developed automatic peak recognition algorithm(P-Find)and machine learning algorithm(subspace K-Nearest Neighbors)were introduced to accurately distinguish the four typical motion behaviors and three primary sub-techniques of cross-country skiing,with accuracy rates of 98.2%and 100%.This work provides a novel strategy to promote the personalized applications of TENGs in intelligent sports.YANG Yun HOU XiaoJuan GENG WenPing MU JiLiang ZHANG Le WANG XiangDong HE Jian XIONG Ji Jun CHOU XiuJian 2022Science China(Technological Sciences)2022,65,4:6
9Integrative taxonomy of the Russet Bush Warbler Locustella mandelli complex reveals a new species from central China显示文摘Background: The Russet Bush Warbler Locustella(previously Bradypterus) mandelli complex occurs in mountains in the eastern Himalayas, southern China, Vietnam, the Philippines, and Indonesia. The taxonomy has been debated,with one(L. seebohmi) to four(L. seebohmi, L. mandelli, L. montis and L. timorensis) species having been recognised.Methods: We used an integrative approach, incorporating analyses of morphology, vocalizations and a molecular marker, to re-evaluate species limits in the L. mandelli complex.Results: We found that central Chinese L. mandelli differed from those from India through northern Southeast Asia to southeast China in plumage, morphometrics and song. All were easily classified by song, and(wing + culmen)/tail ratio overlapped only marginally. Both groups were reciprocally monophyletic in a mitochondrial cytochrome b(cytb) gene tree, with a mean divergence of 1.0 ± 0.2%. They were sympatric and mostly altitudinally segregated in the breeding season in southern Sichuan province. We found that the Mt Victoria(western Myanmar) population differed vocally from other L. mandelli, but no specimens are available. Taiwan Bush Warbler L. alishanensis was sister to the L. mandelli complex, with the most divergent song. Plumage, vocal and cytb evidence supported the distinctness of the south Vietnamese L. mandelli idonea. The Timor Bush Warbler L. timorensis, Javan Bush Warbler L.montis and Benguet Bush Warbler L. seebohmi differed distinctly in plumage, but among-population song variation in L. montis exceeded the differences between some populations of these taxa, and mean pairwise cytb divergences were only 0.5–0.9%. We also found that some L. montis populations differed morphologically.Conclusions: We conclude that the central Chinese population of Russet Bush Warbler represents a new species,which we describe herein, breeding at mid elevations in Sichuan, Shaanxi, Hubei, Hunan and Guizhou provinces.The taxonomic status of the other allopatric populations is less clear. However, as they differ to a degree comparable with that of the sympatric L. mandelli and the new species, we elevate L. idonea to species status, and retain L. seebohmi and L. montis as separate species, the latter with timorensis as a subspecies. Further research should focus on different populations of L. montis and the Mt Victoria population of L. mandelli.Per Alstrom Canwei Xia Pamela C Rasmussen Urban Olsson Bo Dai Jian Zhao Paul J Leader Geoff J Carey Lu Dong Tianlong Cai Paul I Holt Hung Le Manh Gang Song Yang Liu Yanyun Zhang Fumin Lei 2015Chinese Birds2015,,2:4
10First Oligocene mummified plant Lagerst?tte at the low latitudes of East Asia显示文摘Mummified fossils are extraordinarily important for understanding both biotic evolution and ecology in the geological time,by uniquely providing a far more detailed source of information in comparison to impression materials.However,mummified fossils are extremely rare because of the inevitable requirement of unusual preservation conditions during fossilization,including the lithological features and deposition rate of surrounding rocks,and moisture and temperature conditions(Taylor et al.,2009).To date,only a few Cenozoic sites have been reported to yield mummified plant fossils around the world,such as the middleQUAN Cheng FU Qiong Yao SHI Gong Le LIU Yu Sheng LI Long LIU Xiao Yan JIN Jian Hua 2016Science China Earth Sciences2016,59,3:4

12Six new monacolin analogs from red yeast rice显示文摘Six novel monacolin analogs, monacolins V_1–V_6(1–6), together with seven known ones(7–13), were isolated from the ethyl acetate extract of red yeast rice. Their structures and absolute configurations were determined by spectroscopic methods,especially 2D NMR(~1H-~1HCOSY, HSQC, HMBC, and NOESY/ROESY) and CD spectroscopic analyses as well as chemical derivation.Monacolins V_2(2) and V_3(3) represent the first examples of monacolins with 3-hydroxybutyrate substitute. The anti-inflammatory inhibitory activities against the lipopolysaccharide(LPS) induced NO production in BV-2 cells as well as antioxidant activities against rat liver microsomal lipid peroxidation were evaluated.LIU Bing-Yu XU Fei BAI Jian YAN Dao-Jiang ZHANG Le ZHANG Dan HU You-Cai 2019Chinese Journal of Natural Medicines2019,17,5:3
13Validation of the DNATyper^(TM)15 PCR Genotyping System for Forensic Application显示文摘We describe the optimization and validation of the DNATyper^(TM)15 multiplex polymerase chain reaction(PCR)genotyping system for autosomal short tandem repeat(STR)amplification at 14 autosomal loci(D6S1043,D21S11,D7S820,CSF1PO,D2S1338,D3S1358,D13S317,D8S1179,D16S539,Penta E,D5S818,vWA,D18S51,and FGA)and amelogenin,a sex‑determining locus.Several DNATyper^(TM)15 assay variables were optimized,including hot start Taq polymerase concentration,Taq polymerase activation time,magnesium concentration,primer concentration,annealing temperature,reaction volume,and cycle number.The performance of the assay was validated with respect to species specificity,sensitivity to template concentration,stability,accuracy,influence of the DNA extraction methods,and the ability to genotype the mixture samples.The performance of the DNATyper^(TM)15 system on casework samples was compared with that of two widely used STR amplification kits,Identifiler^(TM)(Applied Biosystems,Carlsbad,CA,USA)and PowerPlex 16®(Promega,Madison,WI,USA).The conditions for PCR‑based DNATyper^(TM)15 genotyping were optimized.Contamination from forensically relevant nonhuman DNA was not found to impact genotyping results,and full profiles were generated for all the reactions containing≥0.125 ng of DNA template.No significant difference in performance was observed even after the DNATyper^(TM)15 assay components were subjected to 20 freeze‑thaw cycles.The performances of DNATyper^(TM)15,Identifiler^(TM),and PowerPlex 16®were comparable in terms of sensitivity and the ability to genotype the mixed samples and case‑type samples,with the assays giving the same genotyping results for all the shared loci.The DNA extraction methods did not affect the performance of any of the systems.Our results demonstrate that the DNATyper^(TM)15 system is suitable for genotyping in both forensic DNA database work and case‑type samples.Jian Ye Chengtao Jiang Xingchun Zhao Le Wang Caixia Li Anquan Ji Li Yuan Jing Sun Shuaifeng Chen 2015Journal of Forensic Science and Medicine2015,1,1:3
14Orientation and strain rate dependent tensile behavior of single crystal titanium nanowires by molecular dynamics simulations显示文摘Molecular dynamics simulation was employed to study the tensile behavior of single crystal titanium nanowires(NWs)with1120,1100and[0001]orientations at different strain rates from 10~8s^(-1)to10^(11)s^(-1).When strain rates are above 10^(10)s^(-1),the state transformation from HCP structure to amorphous state leads to super plasticity of Ti NWs,which is similar to FCC NWs.When strain rates are below 10^(10)s^(-1),deformation mechanisms of Ti NWs show strong dependence on orientation.For1120orientated NW,1011compression twins(CTs)and the frequently activated transformation between CTs and deformation faults lead to higher plasticity than the other two orientated NWs.Besides,tensile deformation process along1120orientation is insensitive to strain rate.For 1100orientated NW,prismaticslip is the main deformation mode at 10~8s^(-1).As the strain rate increases,more types of dislocations are activated during plastic deformation process.For[0001]orientated NW,1012extension twinning is the main deformation mechanism,inducing the yield stress of[0001]orientated NW,which has the highest strain rate sensitivity.The number of initial nucleated twins increases while the saturation twin volume fraction decreases nonlinearly with increasing strain rate.Le Chang Chang-Yu Zhou Hong-Xi Liu Jian Li Xiao-Hua He 2018Journal of Materials Science & Technology2018,34,5:3
15Thermal Resistance of Common Rice Maintainer and Restorer Lines to High Temperature During Flowering and Early Grain Filling Stages显示文摘Fifteen common rice maintainer lines and 26 high-yielding restorer lines were used to evaluate their thermal resistance and fertility during flowering and early grain filling stages.The rice plants were subjected to high temperature stress(39-43 ℃) for 1-15 d from main stem flowering.Based on the heat stress index,they were divided into thermal resistant lines,semi-thermal resistant lines,semi-thermal sensitive lines and thermal sensitive lines.Therefore,the maintainer lines K22B,Bobai B and V20B belonged to thermal resistant lines,whereas II-32B,Zhongzhe B and Zhong 9B belonged to thermal sensitive lines.For rice restorer lines,Minghui 63 had the highest thermal resistance,followed by R207,P32,P929,and the lowest thermal resistant lines P62-2-2,R8006 and P51.The correlation analysis indicated that the heat stress index was significantly correlated with seed-setting rate and abortive grain rate under heat stress,but not under natural conditions.This indicated that heat stress occurred during flowering and early grain filling stages mainly decreased the seedsetting rate and significantly increased the abortive grain rate in both rice maintainer and restorer lines.FU Guan-fu SONG Jian XIONG Jie LIAO Xi-yuan ZHANG Xiu-fu WANG Xi LE Ming-kai TAO Long-xing 2012Rice science2012,19,4:3
16Mitochondrial Oxidative Stress Enhances Vasoconstriction by Altering Calcium Homeostasis in Cerebrovascular Smooth Muscle Cells under Simulated Microgravity显示文摘Objective Exposure to microgravity results in postflight cardiovascular deconditioning in astronauts.Vascular oxidative stress injury and mitochondrial dysfunction have been reported during this process.To elucidate the mechanism for this condition,we investigated whether mitochondrial oxidative stress regulates calcium homeostasis and vasoconstriction in hindlimb unweighted(HU)rat cerebral arteries.Methods Three-week HU was used to simulate microgravity in rats.The contractile responses to vasoconstrictors,mitochondrial fission/fusion,Ca^(2+) distribution,inositol 1,4,5-trisphosphate receptor(IP3 R)abundance,and the activities of voltage-gated K+channels(KV)and Ca^(2+)-activated K+channels(BKCa)were examined in rat cerebral vascular smooth muscle cells(VSMCs).Results An increase of cytoplasmic Ca^(2+) and a decrease of mitochondrial/sarcoplasmic reticulum(SR)Ca^(2+) were observed in HU rat cerebral VSMCs.The abundance of fusion proteins(mitofusin 1/2[MFN1/2])and fission proteins(dynamin-related protein 1[DRP1]and fission-mitochondrial 1[FIS1])was significantly downregulated and upregulated,respectively in HU rat cerebral VSMCs.The cerebrovascular contractile responses to vasoconstrictors were enhanced in HU rats compared to control rats,and IP3 R protein/mRNA levels were significantly upregulated.The current densities and open probabilities of KV and BKCa decreased and increased,respectively.Treatment with the mitochondrial-targeted antioxidant mitoTEMPO attenuated mitochondrial fission by upregulating MFN1/2 and downregulating DRP1/FIS1.It also decreased IP3 R expression levels and restored the activities of the KV and BKCa channels.MitoTEMPO restored the Ca^(2+) distribution in VSMCs and attenuated the enhanced vasoconstriction in HU rat cerebral arteries.Conclusion The present results suggest that mitochondrial oxidative stress enhances cerebral vasoconstriction by regulating calcium homeostasis during simulated microgravity.LIU Zi Fan WANG Hai Ming JIANG Min WANG Lin LIN Le Jian ZHAO Yun Zhang SHAO Jun Jie ZHOU Jing Jing XIE Man Jiang LI Xin ZHANG Ran 2021Biomedical and Environmental Sciences2021,34,3:3

18Time-resolved fluoroimmunoassay for quantitative determination of tylosin and tilmicosin in edible animal tissues显示文摘To quantitatively determine tylosin and tilmicosin in edible animal tissues,a time-resolved fluoroimmunoassay(TRFIA) has been developed and validated.For this purpose,desmycosin-O-carboxymethoxylamine-BSA was fixed onto microtiter plates,standards and samples were loaded and,finally,diluted europium-labeled anti-tylosin antibodies were added.Results show that the limit of detection for tylosin was 0.03 ng mL-1 and that for tilmicosin was 0.05 ng mL-1.The recoveries were 73.6% to 120.5%,with coefficients of variation below 15.6% in various biological matrices spiked with tylosin and tilmicosin at concentrations of 50-200 ngg-1.There was good correlation(R2>0.99) between the TRFIA,an enzyme-linked immunosorbent assay and high performance liquid chromatography data.In conclusion,the new TRFIA is applicable to the detection of tylosin and tilmicosin and is an effective and economical method that will enable high-throughput sample screening.The method is expected to be widely applicable.WEI Shu LE Tao CHEN Yong XU Jian HE HongQiu NIU XiaoDong LUO JinHua 2013Chinese Science Bulletin2013,58,15:3
19A coordinated consistency voltage stability control method of active distribution grid显示文摘The presence of distributed generators(DGs)with high penetration poses new challenges in the management and operation of electrical grids.Due to the local character of DGs,they could in principle be used in emergency situations to prevent a voltage instability event of the grid.In this paper,a certain method is proposed to coordinate the operation of virtual power plant(VPP)and conventional voltage regulation device to improve the static voltage stability of distribution network with the multi-agent framework.The concept and the general framework of this coordinated control system is introduced,and the voltage instable nodes are determined based on the voltage instability indicator.The voltage coordinated control model of the distribution system is established according to the multi-agent consistency control theory and the coordinated controllers for agents are designed by solving a problem with bilinear matrix inequality constraints.The suggested method is implemented on an IEEE 33 nodes test system and the simulation results show its efficiency and validity.Xi YE Jian LE Yongyan LIU Wu ZHOU Kaipei LIU 2018Journal of Modern Power Systems and Clean Energy2018,6,1:2
