1A data-driven health indicator extraction method for aircraft air conditioning system health monitoring显示文摘Prognostics and Health Management(PHM) has become a very important tool in modern commercial aircraft. Considering limited built-in sensing devices on the legacy aircraft model,one of the challenges for airborne system health monitoring is to find an appropriate health indicator that is highly related to the actual degradation state of the system. This paper proposed a novel health indicator extraction method based on the available sensor parameters for the health monitoring of Air Conditioning System(ACS) of a legacy commercial aircraft model. Firstly, a specific Airplane Condition Monitoring System(ACMS) report for ACS health monitoring is defined. Then a non-parametric modeling technique is adopted to calculate the health indicator based on the raw ACMS report data. The proposed method is validated on a single-aisle commercial aircraft widely used for short and medium-haul routes, using more than 6000 ACMS reports collected from a fleet of aircraft during one year. The case study result shows that the proposed health indicator can effectively characterize the degradation state of the ACS, which can provide valuable information for proactive maintenance plan in advance.Jianzhong SUN Chaoyi LI Cui LIU Ziwei GONG Ronghui WANG 2019Chinese Journal of Aeronautics2019,32,2:14

4Danggui Buxue Tang ameliorates bleomycin-induced pulmonary fibrosis in rats through inhibiting transforming growth factor-β1/Smad3/plasminogen activator inhibitor-1 signaling pathway显示文摘OBJECTIVE: To investigate the effect of Danggui Buxue Tang(DBT), a decoction from Traditional Chinese Medicine, on bleomycin-induced pulmonary fibrosis in rats, and to propose the possible underlying mechanism.METHODS: Forty male Sprague-Dawley rats were randomly divided into sham group, model group,prednisone group and DBT group. Pulmonary fibrosis rat model was established by intratracheal injection with bleomycin. Body weight and lung index were monitored. Histopathologic examination and collagen deposition were determined using Hematoxylin and eosin(HE) and Masson's trichrome staining. Immunohistochemistry staining was applied to observe the expression of alpha-smooth muscle actin(α-SMA). m RNA expression of α-SMA,collagen Ⅰ and collagen Ⅲ were measured by realtime fluorescence quantitative PCR(RT-q PCR). Inflammatory cytokines, including tumor necrosis factor alpha(TNF-α), interleukin-6(IL-6) and IL-1β in serum were detected by Enzyme-linked immunosorbent assay. Alkali hydrolysis method was conducted to investigate the content of hydroxyproline(HYP). Transforming growth factor-β1(TGF-β1),Smad3 and plasminogen activator inhibitor-1(PAI-1) protein level were examined by Western blot assay.RESULTS: DBT significantly reduced the severity of bleomycin-induced pulmonary fibrosis and inflammation as indicated by minimizing the lost of weight, and by lowering the levels of lung index, inflammation score, Ashcroft score, collagen volume fraction(%), HYP, α-SMA, collagen Ⅰ, collagen Ⅲ,TNF-α, IL-6, IL-1β, TGF-β1, Smad3 and PAI-1, consistent with the effect of prednisone.CONCLUSION: Our findings suggest that DBT is able to ameliorate the pulmonary fibrosis, the possible mechanism may involve inhibition of pulmonary inflammation and collagen deposition, possibly via suppressing TGF-β1/Smad3/PAI-1 signaling pathway.Wang Jiepeng Fang Chaoyi Wang Shaoxian Fang Fang Chu Xinqiao Liu Na Lu Chenxi Wang Shuo Li Wei 2020Journal of Traditional Chinese Medicine2020,40,2:5
5UPLC-MS metabolomics provides insights into the diff erences between black- and white-shelled Pacifi c oysters Crassostrea gigas显示文摘A variety of shell colors are one of the most fundamental characteristics of molluscs,which have importantly ecological and economic signifi cance.The Pacifi c oyster Crassostrea gigas is distributed in many sea areas around the world and also an aquacultured mollusc with high nutritional value.In this study,the whole soft body and the mantle tissue of black-shelled Pacifi c oyster(BSO)and white-shelled Pacifi c oyster(WSO)with starkly diff erent melanin contents were compared,and the diff erences in physiology and metabolism between BSO and WSO were analyzed.The results of physiological indicators suggested BSO show more melanin,more dry matter,more crude lipid content,and stronger ability to scavenge free radicals than WSO.The altered metabolites of glycerophospholipids,fatty acyls,and steroids revealed diff erent regulatory mechanisms of lipids.The correlation analysis of metabolomics and previously published RNAseq data suggested that BSO and WSO mainly diff ered in the basal metabolic processes,such as lipid,amino acid and purine metabolisms.This study provides insights into the changes in the physiological indictors and the metabolites of oysters with varying melanin content.Xi CHEN Qiuyun JIANG Hongce SONG Lingling LI Chaoyi XIE Baoyu HUANG Yaqiong LIU Meiwei ZHANG Lei WEI Xiaotong WANG 2021Journal of Oceanology and Limnology2021,39,1:2

7Global antimicrobial resistance:a system-wide comprehensive investigation using the Global One Health Index显示文摘Background:Antimicrobial resistance(AMR)is one of the top ten global public health challenges.However,given the lack of a comprehensive assessment of worldwide AMR status,our objective is to develop a One Health-based system-wide evaluation tool on global AMR.Methods:We have further developed the three-hierarchical Global One Health Index(GOHI)-AMR indicator scheme,which consists of five key indicators,17 indicators,and 49 sub-indicators,by incorporating 146 countries'data from diverse authoritative databases,including WHO's Global Antimicrobial Resistance and Use Surveillance System(GLASS)and the European CDC.We investigated the overall-or sub-rankings of GOHI-AMR at the international/regional/national levels for data preprocessing and score calculation utilizing the existing GOHI methodology.Additionally,a correlation analysis was conducted between the GOHI-AMR and other socioeconomic factors.Results:The average GOHI-AMR score for 146 countries is 38.45.As expected,high-income countries(HICs)outperform the other three income groups on overall rankings and all five key indicators of GOHI-AMR,whereas lowincome countries unexpectedly outperform upper-middle-income countries and lower-middle-income countries on the antibiotics-resistant key indicator(ARR)and ARR-subordinate indicators,including carbapenem-,β-lactam-,and quinolone resistance,and even HICs on aminoglycoside resistance.There were no significant differences among the four groups on the environmental-monitoring indicator(P>0.05).GOHI-AMR was positively correlated with gross domestic product,life expectancy,and AMR-related publications,but negatively with natural growth rate and chronic respiratory disease.In contrast to Cyprus,the remarkably lower prevalence of'ESKAPE pathogens'in high-scoring Sweden and Denmark highlights Europe's huge gaps.China and Russia outperformed the other three BRICS countries on all key indicators,particularly India's ARR and Brazil's AMR laboratory network and coordination capacity.Furthermore,significant internal disparities in carbapenem-resistant Klebsiella pneumoniae(CRKP)and methicillin-resistant Staphylococcus aureus(MRSA)prevalence were observed between China and the USA,with MRSA prevalence both gradually declining,whereas CRKP prevalence has been declining in the USA but increasing in China,consistent with higher carbapenems-related indicator'performance in USA.Conclusions:GOHI-AMR is the most comprehensive tool currently available for the assessment of AMR status worldwide.We discovered unique features impacting AMR in each country and offered precise recommendations to improve the capacity to tackle AMR in low-ranking countries.Nan Zhou Zile Cheng Xiaoxi Zhang Chao Lv Chaoyi Guo Haodong Liu Ke Dong Yan Zhang Chang Liu Yunfu Chang Sheng Chen Xiaokui Guo Xiao-Nong Zhou Min Li Yongzhang Zhu 2022Infectious Diseases of Poverty2022,11,4:2
8Safety Assessment of Heavy Metal in Tea Garden Soil: A Case Study of Specialized Tea Towns in Guangdong显示文摘More than 20 soil samples were collected from tea gardens of specialized tea towns in Guangdong,including Fenglang Town and Fengshun Town in Meizhou City,Changshan Town in Lianjiang City,Fenghuang Town in Chaozhou City.Content of 6 types of heavy metal (Cr,Cu,Pb,As,Cd,Hg) in tea garden soil was measured.On the basis of these,the safety was assessed.Results show that the comprehensive pollution index of these 6 types of heavy metal is lower than 0.7.According to Soil Pollution Grading Standard formulated by China Green Food Development Center,the soil is not polluted by heavy metal and remains at safety level.It proves that overall soil condition of specialized tea gardens in Guangdong Province is not polluted by heavy metal.Qiushuang WANG Caijin LING Shumei LIU Junxi CAO Jinsong ZHANG Chaoyi ZHAO 2013Asian Agricultural Research2013,5,8:1
9Reductive damage induced autophagy inhibition for tumor therapy显示文摘Numerous therapeutic anti-tumor strategies have been developed in recent decades.However,their therapeutic efficacy is reduced by the intrinsic protective autophagy of tumors.Autophagy plays a key role in tumorigenesis and tumor treatment,in which the overproduction of reactive oxygen species(ROS)is recognized as the direct cause of protective autophagy.Only a few molecules have been employed as autophagy inhibitors in tumor therapy to reduce protective autophagy.Among them,hydroxychloroquine is the most commonly used autophagy inhibitor in clinics,but it is severely limited by its high therapeutic dose,significant toxicity,poor reversal efficacy,and nonspecific action.Herein,we demonstrate a reductive-damage strategy to enable tumor therapy by the inhibition of protective autophagy via the catalytic scavenging of ROS using porous nanorods of ceria(PN-CeO_(2))nanozymes as autophagy inhibitor.The antineoplastic effects of PN-CeO_(2)were mediated by its high reductive activity for intratumoral ROS degradation,thereby inhibiting protective autophagy and activating apoptosis by suppressing the activities of phosphatidylinositide 3-kinase/protein kinase B and p38 mitogen-activated protein kinase pathways in human cutaneous squamous cell carcinoma.Further investigation highlighted PN-CeO_(2)as a safe and efficient anti-tumor autophagy inhibitor.Overall,this study presents a reductive-damage strategy as a promising anti-tumor approach that catalytically inhibits autophagy and activates the intrinsic antioxidant pathways of tumor cells and also shows its potential for the therapy of other autophagy-related diseases.Yuqian Wang Yingjian Huang Yu Fu Zhixiong Guo Da Chen Fangxian Cao Qi Ye Qiqi Duan Meng Liu Ning Wang Dan Han Chaoyi Qu Zhimin Tian Yongquan Qu Yan Zheng 2023Nano Research2023,16,4:1

11Interaction between neutrophil extracellular traps and cardiomyocytes contributes to atrial fibrillation progression显示文摘Atrial fibrillation(AF)is a frequent arrhythmia associated with cardiovascular morbidity and mortality.Neutrophil extracellular traps(NETs)are DNA fragments with cytoplasm proteins released from neutrophils,which are involved in various cardiovascular diseases.To elucidate the role of NETs in AF,we investigated the effect of NETs on AF progression and the secretion of NETs in AF.Results showed that:NETs induced the autophagic apoptosis of cardiomyocytes,and NETs also led to mitochondrial injury by promoting mitochondrial depolarization and ROS production.Ongoing tachy-pacing led to the structural loss of cardiomyocytes and provided potent stimuli to induce NETs secretion from neutrophils.In the meanwhile,increased Ang II in AF facilitated NETs formation through the upregulation of AKT phosphorylation,while it could not directly initiate NETosis as the autophagy was not induced.In vivo,DNase I was administrated to abrogate NETs formation,and AF-related fibrosis was ameliorated as expected.Correspondingly,the duration of the induced AF was reduced.Our study addresses the formation mechanism of NETs in AF and demonstrates the lethal effects of NETs on cardiomyocytes through the induction of mitochondrial injury and autophagic cell death,which comprehensively describes the positive feedback comprised of NETs and stimuli secreted by cardiomyocytes that sustains the progression of AF and AF related fibrosis.Li He Ruiqi Liu Honghua Yue Xiaoxin Zhang Xiaohui Pan Yutao Sun Jun Shi Guonian Zhu Chaoyi Qin Yingqiang Guo 2023Signal Transduction and Targeted Therapy2023,8,8:1
12Mass-producible low-cost flexible electronic fabrics for azo dye wastewater treatment by electrocoagulation显示文摘Electrocoagulation is progressively becoming an ecologically friendly water treatment method owing to its lack of secondary pollution,high active ingredient concentration,high treatment effectiveness,simple equipment,and simplicity of automated control implementation.Herein,electrocoagulation is offered as a method for treating wastewater containing azo dyes using a revolutionary flexible electronic fabric that can be mass-producible at a reasonable price.A computer-controlled machine embroiders 316L stainless steel fiber(316L SSF)onto an insulating fabric to manufacture a flexible electronic device of cathode and anode with a monopolar arrangement on the fabric surface.Using methyl orange(MO)solution to simulate azo dye wastewater,the decolorization rate of 500 ml MO reached 99.25% under the conditions of 50 mg·L^(-1)initial mass concentration,120 min electrolysis time,15 mA·g^(-1)current density,1 cm electrode spacing,0.1 mol·L^(-1)NaCl,pH 7.6,200 r·min^(-1)rotational speed of the stirrer,and 22-25℃ room temperature.In addition,it is feasible to embroider flexible electronic fabrics with varied sizes and numbers of electrodes based on the amount of treated sewage to increase the degradation rate,which has significant practical application value.Chaoyi Yin Jingyuan Ma Jian Qiu Ruifang Liu Long Ba 2023Chinese Journal of Chemical Engineering2023,59,7:0
132-4 First Isochronous Mass Measurement in Neutron-rich Region at CSRe显示文摘Mass is one of the fundamental properties of atomic nuclei. Isochronous mass spectrometry (IMS), using astorage ring combined with an in-flight separator, has been shown to be a powerful tool for mass measurementof exotic nuclei[1]. Recently, masses of many proton-rich nuclides were accurately determined at the HIRFL-CSRfacility[2]. In this paper, we described the first isochronous mass measurement of neutron-rich nuclides at CSRe.This experiment was performed at the end of 2011. In the experiment, the primary beam of 86Kr28+ ions wasaccumulated and accelerated to an energy of 460.65 MeV/u in the synchrotron CSRm. The 86Kr28+ ions were fastextracted and focused on a 15 mm thick beryllium target which was placed at the entrance of the RIBLL2 (anin-flight fragment separator).Xu Xing Wang Meng Zhang Yuhu Xu Hushan Tu Xiaolin Yu.A.Litvinov Zhou Xiaohong Sun Baohua Yuan Youjin Xia Jiawen Yang Jiancheng K.Blaum Chen Ruijiu Chen Xiangchen Fu Chaoyi Ge Zhuang Hu Zhengguo Huang Wenjia Liu Dawei Y.H.Lam Ma Xinwen Mao Ruishi T.Uesaka Xiao Guoqing Xing Yuanming T.Yamaguchi Y.Yamaguchi Zeng Qi Yan Xinliang Zhao Hongwei Zhao Tiecheng Zhang Wei Zhan Wenlong 2014IMP & HIRFL Annual Report2014,,1:0
142-6 First Isochronous Mass Measurements with Two Time-of-Flight Detectors at CSRe显示文摘In conventional isochronous mass spectrometry (IMS), single time-of-flight (TOF) method is adopted to measurethe ions' revolution times in a storage ring which can then be used to calculate the ions' masses. However, themass-to-charge ratio (m=q) is only related to the revolution time (T) under the condition that is equal to taccording to the following equation:Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Shuai Peng Xu Xing Chen Ruijiu Yan Xinliang Tu Xiaolin Zhang Wei Fu Chaoyi Zeng Qi Yu.A.Litvinov K.Blaum Chen Xiangcheng Ge Zhuang Gao Bingshui Huang Wenjia S.A.Litvinov Liu Dawei Ma Xinwen Mao Ruishi Xiao Guoqing Yang Jiancheng Yuan Youjin Zhou Xiaohong 2014IMP & HIRFL Annual Report2014,,1:0
152-8 SimCSR Program for the Simulation of the Isochronous Mass Spectrometry at the HIRFL-CSR显示文摘Until now, several isochronous mass spectrometry (IMS) experiments have been successfully performed usingvarious primary beams at the HIRFL-CSR and masses of both proton-rich and proton-deficient exotic nuclei havebeen measured. In order to improve the performance of the IMS experiments and to provide a reliable tool fordesigning and preparing the future experiments, a simulation code, named SimCSR is developed.Presently, six-dimension phase-space linear transmission theory is applied to simulate the transmission of ionsin the experimental storage ring (CSRe). The basic algorithm is Bf = MBi. The Bi and Bf are six-dimensionphase-space vectors of ions at the entrance and exit of each element of the CSRe lattice, respectively. M is a6-by-6-dimension first-order transfer matrix of each element. M is calculated using formulas described in Ref.[1]. Inthe simulations, the ring lattice is considered in detail, and the same magnetic setting as in our previous experimentwith 58Ni projectile fragments[2] is considered. The ions are assumed to circulate 300 turns inside the CSRe.Chen Ruijiu Yuan Youjin Wang Meng Xu Xing Shuai Peng Zhang Yuhu Yan Xinliang Xing Yuanming Xu Hushan Zhou Xiaohong Litvinov Yuri Litvinov Sergy Chen Xiangcheng Fu Chaoyi Ge Wenwen Ge Zhuang Hu Xuejing Huang Wenjia Liu Dawei Zeng Qi Zhang Wei 2014IMP & HIRFL Annual Report2014,,1:0
162-9 Half-life Measurement of 94mRu44+ at CSRe显示文摘A radioactive nucleus is characterized with an intrinsic half-life. However, for a nuclear species, the half-lives inneutral atoms could be very different from that in highly charged ions. The half-lives of some highly charged ionshave been directly measured at GSI for multiple motivations[1]. In the same case, the nuclear state(i:e the isomer)may be in the range of several tens of microseconds and their half-live can be measured using isochronous massspectrometry. The J = 8+ isomeric state in 94Ru was chosen to test this method. The half-life of this isomer is71 s [2] in neutral atoms, and the excitation energy is 2.64 MeV. The internal conversion coefficient of this decayin neutral atom is 0.335. So its half-life in the bare nucleus would be modified to be 94.78 s when the internalconversion channel is blocked.Zeng Qi Zhang Yuhu Wang Meng Xu Hushan Tu Xiaolin Zhou Xiaohong Yan Xinliang Chen Ruijiu Huang Wenjia Ge Zhuang Liu Dawei Fu Chaoyi Sun Mingze Mei Bo Xu Xing Xing Yuanming Shuai Peng Zang Yongdong Zhang Wei Xiao Guoqing Yu.A.Litvinov Isao.Tanihata 2014IMP & HIRFL Annual Report2014,,1:0
17Zhenxin Anshen formula(镇心安神方)ameliorates atopic der-matitis-like skin dysfunction in mice and in vitro via regulation of transient receptor potential vanilloid 1 and transient receptor potential ankyrin 1 in Neural pathways显示文摘OBJECTIVE:To investigate the efficacy of Zhenxin Anshen formula(镇心安神方,ZXAS)on atopic dermatitis(AD)by transient receptor potential vanilloid 1(TRPV1)and transient receptor potential ankyrin 1(TRPA1)signalling pathway in mice and in vitro.METHODS:AD-like lesions were induced by 1-chloro-2,4-dinitrobenzene(DNCB)to the shaved dorsal skin of BALB/c mice.BALB/c mice were divided into five groups:normal control,model control,cetirizine,low-,medium-,and high-dose of ZXAS.After ZXAS in-tervention,the skin lesions and blood samples were collected for hematoxylin and eosin-stained and measuring the concentrations of inflammatory cytokines.Immunoglobulin E(IgE),interleukin(IL)-4,IL-5,IL-13,and thymic stromal lymphopoietin(TSLP)were de-tected by Enzyme-linked immunosorbent assay(ELISA).The spinal cords were collected for measuring the expression of gastrin-releasing peptide receptor(GRPR),TRPV1,and TRPA1 by using immunohistochemistry,western blotting,and quantitative real-time polymerase chain reaction(qR T-PCR)analyses.In addition,3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide(MTT)assay,flow cytometry,ELISA,and Western blotting were conducted for analysis of primary dorsal root ganglia(DRG)neurons in vitro.RESULTS:ZXAS treatment improved DNCB-induced AD-like lesions through reducing dermatitis score,number of scratching and epidermal thickness,accompanied by the de-creased IgE and Th2 inflammatory cytokines.ZXAS also supressed the mRNA and protein expression of GRPR,TRPV1,and TRPA1 in the spinal cord.The medicated sera of ZXAS decreased capsaicin-induced Ca^(2+)influx and downregulated the expression of TRPV1,TRPA1,and phospholipase C in DRG neurons.CONCLUSIONS:The therapeutic effect of ZXAS on AD may be related to the regulation of TRPV1 and TRPA1 and inhibition of Ca^(2+)signals in neurons.ZHAO Yiding YAN Xiaoning JIANG Shanshan LIU Yong DONG Chun CHI Huiyan MAO Chaoyi 2023Journal of Traditional Chinese Medicine2023,43,5:0
18Evaluating cost and benefit of air pollution control policies in China:A systematic review显示文摘China has put great efforts into air pollution control over the past years and recently committed to its most ambitious climate target.Cost and benefit analysis has been widely used to evaluate the control policies in terms of past performance,future reduction potential,and direct and indirect impacts.To understand the cost and benefit analysis for air pollution control in China,we conducted a bibliometric review of more than 100 studies published over the past two decades,including the current research progress,most commonly adopted methods,and core findings.The control target in cost and benefit analysis has shifted in three stages,from individual and primary pollution control,moving to joint prevention of multiple and secondary pollutants,and then towards synergistic control of air pollution and carbon.With the expansion of the research scope,the integrated assessment model has gradually demonstrated the necessity for long-term ex-anti policy simulation,especially for dealing with complex factors.To ensure long-term air quality,climate,public health,and sustainable economic development,substantial evidence from published studies has suggested that China needs to continue its efforts in the upstream adjustment of the energy system and industrial structure with multi-regional and-sector collaboration.This cost and benefit review paper provides decision-makers with the fundamental information and knowledge gaps in air pollution control strategies in China,and direction for facing future challenges.Xinyuan Liu Chaoyi Guo Yazhen Wu Chen Huang Keding Lu Yuanhang Zhang Lei Duan Miaomiao Cheng Fahe Chai Fengqiao Mei Hancheng Dai 2023Journal of Environmental Sciences2023,,1:0
