1Particle size distribution and characteristics of polycyclic aromatic hydrocarbons during a heavy haze episode in Nanjing,China显示文摘A heavy haze episode caused by agricultural burning occurred in Nanjing from November 7 to November8,2009.PM_(10) samples were collected on normal and hazy days from November 1 to November 14,2009 at both city and suburban sites of Nanjing.Sixteen PAHs were measured during the day and at night.The results show that the concentrations of the particles were as high as 579.55 and 573.43 μg/m^3 during the haze episode at the city and suburban sites,respectively,3-4 times higher than those on a normal day.The proportions of fine particles during the haze episode were also higher than those on a normal day.The changes in the concentrations of PAHs were in accordance with the concentrations of the particles.Highmolecular-weight PAHs composed approximately 80% of the total PAHs on normal days and during the haze episode.The concentration of PAHs in fine fractions significantly increased during the haze episode,and this increase was most obvious at night at the city site.The proportion of total carcinogenic PAHs in fine particles was relatively high during the haze episode at both sampling sites,particularly at night at the city site.Qingzi Meng Shuxian Fan Jiabao He Jian Zhang Yu Sun Yue Zhang Fan Zu 2015Particuology2015,13,1:16
2Distribution management system framework based on security region for future low carbon distribution systems显示文摘In this paper,a new Distribution Management System(DMS)framework based on security region is proposed.First,the concept of Distribution System Security Region(DSSR)is introduced.DSSR is capable to describe the N-1 security boundary of the whole distribution network,including the secure output range of DGs.This new theoretic tool provides a chance for the implementation of real-time security analysis and active controls in DMS.Second,this paper proposes and describes five security states for distribution system.Third,an upgraded DMS enhanced with DSSR is proposed,which consists of advanced security functions such as preventive and predictive control of the trajectory of operating points.Finally,a practical case is presented to simulate the proposed DSSR-enhanced DMS,in which both the security region of network and the output range of DGs are calculated.Typical security functions are also demonstrated.In conclusion,the new DMS framework aims to help operate the system closed to its security boundary in order to improve the efficiency significantly within same security standard.This work is beneficial for future low carbon distribution systems with high penetration rate of DGs.Jun XIAO Qibo HE Guoqiang ZU 2015Journal of Modern Power Systems and Clean Energy2015,3,4:10
3Evaluation of three tracers for labeling distal cerebrospinal fluidcontacting neurons显示文摘It has been reported that distal cerebrospinal fluidcontacting neurons(dCSF-CNs)can be detected by immunohistochemical assay using cholera toxin subunit B-conjugated horseradish peroxidase(CBHRP).In the present study,another two methods with CB alone or CB-conjugated FITC(CB-FITC)were used,and the results from the three methods were compared.Adult Sprague-Dawley rats were randomly divided into three groups with CB-HRP,CB or CB-FITC.Tracers were diluted to 30%in artificial cerebrospinal fluid and injected separately(in a volume of 3μL)into the lateral ventricle.Animals from the CB-HRP and CB groups were perfused 48 h after surgery while animals from the CB-FITC group were perfused 1,3,6,12,24 or 48 h after surgery.The brain was sectioned(40μm)for immunofluorescence and five sections with positive neurons were selected from each rat for neuron counting.Three clusters of positive neurons in a'Y-like'distribution were detected ventral to the cerebral aqueduct of rats from the three groups.No significant difference was observed among the quantitative data.In the CB-FITC group,stable staining was detected even at 6 h after injection.Taken together,lateral ventricle injection of CB/CB-FITC is a useful method for labeling dCSFCNs in rats.The CB-FITC method makes dCSF-CNs labeling much simpler and more convenient.Fang Zhou Jiayou Wang Hongxing Zhang He Liu Guangping Zhao Cuihua Zu Xiaoxing Lu Licai Zhang 2013Neuroscience Bulletin2013,29,5:7
4MiR-125a-5p Regulates Vitamin D Receptor Expression in a Mouse Model of Experimental Autoimmune Encephalomyelitis显示文摘Multiple sclerosis(MS)is a chronic and incurable autoimmune neurodegenerative disease of the central nervous system.Although the symptoms of MS can be managed by vitamin D3 treatment alone,this condition cannot be completely eradicated.Thus,there might be unknown factors capable of regulating the vitamin D receptor(VDR).Genome-wide analysis showed that miRNAs were associated with VDRs.We sought to determine the role and mechanism of action of miRNA-125a-5p and VDRs in a model of MS,mice with experimental autoimmune encephalomyelitis(EAE),which was induced by myelin oligodendrocyte glycoprotein 35–55 peptides.EAE mice showed decreased mean body weight but increased mean clinical scores compared with vehicle or control mice.And inflammatory infiltration was found in the lumbosacral spinal cord of EAE mice.In addition,VDR expression was significantly lower while the expression of miR-125a-5p was markedly higher in the spinal ventral horn of EAE mice than in vehicle or control mice.Importantly,activation of VDRs by paricalcitol or inhibition of miR-125a-5p by its antagomir markedly decreased the mean clinical scores in EAE mice.Interestingly,VDR and miR-125a-5p were co-localized in the same neurons of the ventral horn.More importantly,inhibition of miR-125a-5p remarkably blocked the decrease of VDRs in EAE mice.These results support a critical role for miR-125a-5p in modulating VDR activity in EAE and suggest potential novel therapeutic interventions.Han-Chun Long Rui Wu Chun-Feng Liu Fei-Long Xiong Zu Xu Dian He Yi-Fan Zhang Bing Shao Ping-An Zhang Guang-Yin Xu Lan Chu 2020Neuroscience Bulletin2020,36,2:6

625-Hydroxycholesterol is a potent SARS-CoV-2 inhibitor显示文摘Dear Editor,As of July,2020,the ongoing pandemic of coronavirus diseases 2019(COVID-19)caused by the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2,previously 2019-nCoV)has caused more than 10.3 million human infections,with more than 506,000 deaths worldwide according to the World Health Organization.The clinical manifestations of COVID-19 vary from no asymptomatic infection,mild“flu-like”symptoms,to lethal acute respiratory distress syndrome.The case mortality and fatality rates in people infected with SARS-CoV-2 increase steeply with age,and fatal outcomes are almost exclusively seen in people older than 50 years.1 Although the Food and Drug Administration has authorized emergency use of remdesivir for COVID-19 treatment in the US,the need for safe and effective antiviral drugs against SARS-CoV-2 remains urgent and unmet.Shulong Zu Yong-Qiang Deng Chao Zhou Jie Li Lili Li Qi Chen Xiao-Feng Li Hui Zhao Sarah Gold Jun He Xiang Li Changqing Zhang Heng Yang Genhong Cheng Cheng-Feng Qin 2020Cell Research2020,30,11:3
7Genetically modified CD7-targeting allogeneic CAR-T cell therapy with enhanced efficacy for relapsed/refractory CD7-positive hematological malignancies:a phase I clinical study显示文摘Chimeric antigen receptor(CAR)-T cell therapy against T cell malignancies faces major challenges including fratricide between CAR-T cells and product contamination from the blasts.Allogeneic CAR-T cells,generated from healthy donor T cells,can provide ready-to-use,blast-free therapeutic products,but their application could be complicated by graft-versus-host disease(GvHD)and host rejection.Here we developed healthy donor-derived,CD7-targeting CAR-T cells(RD13-01)with genetic modifications to resist fratricide,GvHD and allogeneic rejection,as well as to potentiate antitumor function.A phase I clinical trial(NCT04538599)was conducted with twelve patients recruited(eleven with T cell leukemia/lymphoma,and one with CD7-expressing acute myeloid leukemia).All patients achieved pre-set end points and eleven proceeded to efficacy evaluation.No dose-limiting toxicity,GvHD,immune effector cell-associated neurotoxicity or severe cytokine release syndrome(grade≥3)were observed.28 days post infusion,81.8%of patients(9/11)showed objective responses and the complete response rate was 63.6%(7/11,including the patient with AML).3 of the responding patients were bridged to allogeneic hematopoietic stem cell transplantation.With a median follow-up of 10.5 months,4 patients remained in complete remission.Cytomegalovirus(CMV)and/or Epstein-Barr virus(EBV)reactivation was observed in several patients,and one died from EBV-associated diffuse large B-cell lymphoma(DLBCL).Expansion of CD7-negative normal T cells was detected post infusion.In summary,we present the first report of a Phase I clinical trial using healthy donor-derived CD7-targeting allogeneic CAR-T cells to treat CD7^(+)hematological malignancies.Our results demonstrated the encouraging safety and efficacy profiles of the RD13-01 allogeneic CAR-T cells for CD7^(+)tumors.Yongxian Hu Yali Zhou Mingming Zhang Houli Zhao Guoqing Wei Wengang Ge Qu Cui Qitian Mu Gong Chen Lu Han Tingting Guo Jiazhen Cui Xiaoyan Jiang Xiujun Zheng Shuhui Yu Xiaolong Li Xingwang Zhang Mingxi Chen Xiuju Li Ming Gao Kang Wang Cheng Zu Hao Zhang Xiaohong He Yanbin Wang Dongrui Wang Jiangtao Ren He Huang 2022Cell Research2022,32,11:2
8Gaseous emissions from compressed natural gas buses in urban road and highway tests in China显示文摘The natural gas vehicle market is rapidly developing throughout the world, and the majority of such vehicles operate on compressed natural gas(CNG). However, most studies on the emission characteristics of CNG vehicles rely on laboratory chassis dynamometer measurements, which do not accurately represent actual road driving conditions. To further investigate the emission characteristics of CNG vehicles, two CNG city buses and two CNG coaches were tested on public urban roads and highway sections. Our results show that when speeds of 0–10 km/hr were increased to 10–20 km/hr, the CO_2, CO, nitrogen oxide(NO_x), and total hydrocarbon(THC) emission factors decreased by(71.6 ± 4.3)%,(65.6 ± 9.5)%,(64.9 ± 9.2)% and(67.8 ± 0.3)%, respectively. In this study, The Beijing city buses with stricter emission standards(Euro Ⅳ) did not have lower emission factors than the Chongqing coaches with Euro Ⅱ emission standards. Both the higher emission factors at 0–10 km/hr speeds and the higher percentage of driving in the low-speed regime during the entire road cycle may have contributed to the higher CO_2 and CO emission factors of these city buses. Additionally, compared with the emission factors produced in the urban road tests, the CO emission factors of the CNG buses in highway tests decreased the most(by 83.2%), followed by the THC emission factors, which decreased by 67.1%.Tingting Yue Fahe Chai Jingnan Hu Ming Jia Xiaofeng Bao Zhenhua Li Liqang He Lei Zu 2016Journal of Environmental Sciences2016,28,10:2

12Effect of Ga_2O_3 on Structure and Properties of Calcium Aluminate Glasses显示文摘The effect of Ga_2O_3 on the structure and properties of calcium aluminate glasses fabricated by vacuum melting process was investigated by Raman spectrum, differential scanning calorimeter(DSC), and infrared spectrum methods. The results show that calcium aluminate glass network only consists of [AlO_4] tetrahedral units. With the gradual addition of Ga_2O_3, the quantity of [GaO_4] tetrahedral units increases. Substitution of Ga_2O_3 for Al_2O_3 results in a decrease in Tg, Tx, and Tp, and an increase in the thermal stable index ΔT. Similarly, the absorption band around 3.0 μm obviously reduces and the transparency in 4.0-6.0 μm rapidly increases with increasing Ga_2O_3 content. However, the chemical stability of calcium aluminate glasses decreases if Ga_2O_3 is introduced due to the increasing of [GaO_4] units in the glass network.王衍行 ZU Chengkui HE Kun ZHAO Huifeng LIU Yonghua 2016Journal of Wuhan University of Technology(Materials Science)2016,31,5:1

14Exploring pathogenesis in subjects with subjective Tinnitus having kidney deficiency pattern in terms of Traditional Chinese Medicine based on serum metabolic profiles显示文摘OBJECTIVE: To investigate the metabolic pathogenesis in subjects with subjective tinnitus(ST)having kidney deficiency pattern(KDP)(ST/KDP) in terms of Traditional Chinese Medicine.METHODS: Three groups of subjects, including healthy individuals, subjects with ST/KDP, and subjects who were healthy initially and then developed ST/KDP one year later(healthy → ST/KDP),were recruited for this study. Serum metabolic profiles of all subjects were analyzed using ultra-performance liquid chromatography coupled with quadruple-time-of-flight mass spectrometry. The metabolic characteristics of the ST/KDP subjects were determined, and the corresponding biomarkers were predicted. The metabolomics data from the healthy → ST/KDP subjects were collected for further verification.RESULTS: Twelve metabolites in the ST/KDP subjects were different from those of the healthy control subjects. Of these metabolites, according to the prediction, except for octanoic acid, other metabolites might characterize ST/KDP. Ten metabolites at the outcome ST/KDP stage were different from those at the initial(control) stage. Through the comparison of these metabolites with the predicted metabolites, five common metabolites, including upregulated glutamate, serotonin, oroticacid and 8-oxoguanine, as well as downregulated taurine, were found. These common metabolites were significantly associated with canonical pathways including calcium signaling, γ-aminobutyric acid(GABA) receptor signaling, purine and pyrimidine biosynthesis, taurine biosynthesis, and serotonin receptor signaling.CONCLUSION: The metabolic pathogenesis in ST/KDP subjects was characterized by upregulated glutamate, serotonin, orotic acid and 8-oxoguanine, as well as downregulated taurine, additionally, perturbations of calcium signaling, GABA receptor signaling, purine and pyrimidine biosynthesis, taurine biosynthesis, and serotonin receptor signaling.Tan Yong Shen Shanshan Guan Fulan He Bing Lu Cheng Xiao Cheng Jiang Miao Zhao Ning Li Li Cheng Shiping Zu Xianpeng Zhang Weidong Liu Xinru Lü Aiping 2018Journal of Traditional Chinese Medicine2018,38,5:1
