3Dexmedetomidine attenuates traumatic brain injury: action pathway and mechanisms显示文摘Traumatic brain injury induces potent inflammatory responses that can exacerbate secondary blood-brain barrier(BBB) disruption, neuronal injury, and neurological dysfunction. Dexmedetomidine is a novel α2-adrenergic receptor agonist that exert protective effects in various central nervous system diseases. The present study was designed to investigate the neuroprotective action of dexmedetomidine in a mouse traumatic brain injury model, and to explore the possible mechanisms. Adult male C57 BL/6 J mice were subjected to controlled cortical impact. After injury, animals received 3 days of consecutive dexmedetomidine therapy(25 μg/kg per day). The modified neurological severity score was used to assess neurological deficits. The rotarod test was used to evaluate accurate motor coordination and balance. Immunofluorescence was used to determine expression of ionized calcium binding adapter molecule-1, myeloperoxidase, and zonula occluden-1 at the injury site. An enzyme linked immunosorbent assay was used to measure the concentration of interleukin-1β(IL-1β), tumor necrosis factor α, and IL-6. The dry-wet weight method was used to measure brain water content. The Evans blue dye extravasation assay was used to measure BBB disruption. Western blot assay was used to measure protein expression of nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3(NLRP3), caspase-1 p20, IL-1β, nuclear factor kappa B(NF-κB) p65, occluding, and zonula occluden-1. Flow cytometry was used to measure cellular apoptosis. Results showed that dexmedetomidine treatment attenuated early neurological dysfunction and brain edema. Further, dexmedetomidine attenuated post-traumatic inflammation, up-regulated tight junction protein expression, and reduced secondary BBB damage and apoptosis. These protective effects were accompanied by down-regulation of the NF-κB and NLRP3 inflammasome pathways. These findings suggest that dexmedetomidine exhibits neuroprotective effects against acute(3 days) post-traumatic inflammatory responses, potentially via suppression of NF-κB and NLRP3 inflammasome activation.Dong Wang Xin Xu Yin-Gang Wu Li Lyu Zi-Wei Zhou Jian-Ning Zhang 2018Neural Regeneration Research2018,13,5:19
4Internet of Vehicles in Big Data Era显示文摘As the rapid development of automotive telematics,modern vehicles are expected to be connected through heterogeneous radio access technologies and are able to exchange massive information with their surrounding environment. By significantly expanding the network scale and conducting both real-time and long-term information processing, the traditional Vehicular AdHoc Networks(VANETs) are evolving to the Internet of Vehicles(Io V), which promises efficient and intelligent prospect for the future transportation system. On the other hand, vehicles are not only consuming but also generating a huge amount and enormous types of data, which is referred to as Big Data. In this article, we first investigate the relationship between Io V and big data in vehicular environment, mainly on how Io V supports the transmission, storage, computing of the big data, and how Io V benefits from big data in terms of Io V characterization,performance evaluation and big data assisted communication protocol design. We then investigate the application of Io V big data in autonomous vehicles. Finally, the emerging issues of the big data enabled Io V are discussed.Wenchao Xu Haibo Zhou Nan Cheng Feng Lyu Weisen Shi Jiayin Chen Xuemin (Sherman) Shen 2018IEEE/CAA Journal of Automatica Sinica2018,5,1:19
5Evaluation of the Effects of Standard Rescue Procedure on Severe Trauma Treatment in China显示文摘Xiao-Feng Yin Tian-Bing Wang Pei-Xun Zhang Yu-Hui Kou Dian-Ying Zhang Kai Yu De-Cheng Lyu Mao-Zheng Liu Dong-Sheng Zhou Peng Zhang Jue-Hua Jing Wei-Wei Ge Li-Ying Cao Guo-Sheng Wang Shao-Jie Deng Weng-Hua Liu Mao Zhang Yong-An Xu Kun Zhang Bing Li Wei Wang Zhong-Li Gao Cheng-La Yi Bao-Guo Jiang 2015Chinese Medical Journal2015,,10:18

7Identification of a Newly Isolated Getah Virus in the China-Laos Border,China显示文摘In this study, we isolated a virus strain(YN12031) from specimens of Armigeres subalbatus collected in the China-Laos border. BHK-21 cells infected with YN12031 exhibited an evident cytopathic effect(CPE) 32 h post-infection. The virus particles were spherical, 70 nm in diameter, and enveloped; they also featured surface fibers. Molecular genetic analysis revealed that YN12031 was closely related to alpha viruses such as Chikungunya virus and Sindbis virus, and located in the same clade as MM2021, the prototype of Getahvirus(GETV) isolated in Malaysia in 1955. Phylogenetic analysis of the E2 and capsid genes further revealed that YN12031 was located in the same clade as the Russian isolate LEIV/16275/Mag. Analysis of the homology of nucleotides and amino acids in the coding area and E2 gene demonstrated that the YN12031 isolated from the China-Laos border(tropical region) was related closest to the LEIV/16275/Mag isolate obtained in Russia(North frigid zone area) among other isolates studied. These results suggest that GETV can adapt to different geographical environments to propagate and evolve. Thus, strengthening the detection and monitoring of GETV and its related diseases is very crucial.LI Yuan Yuan FU Shi Hong GUO Xiao Fang LEI Wen Wen LI Xiao Long SONG Jing Dong CAO Lei GAO Xiao Yan LYU Zhi HE Ying WANG Huan Yu REN Xiao Jie ZHOU Hong Ning WANG Gui Qin LIANG Guo Dong 2017Biomedical and Environmental Sciences2017,30,3:12
8Field test of best management practice pollutant removal efficiencies in Shenzhen,China显示文摘This paper presents a study on the use of best management practices(BMPs)for controlling nonpoint pollution in the Xikeng Reservoir watershed located in Shenzhen,China.A BMP treatment train design,including a pond,a wetland,and a buffer strip placed in series was implemented at the reservoir location.A separate grass swale was also constructed at the site.Low impact development(LID)BMPs,namely a planter box and bioboxes,were used at the parking lot of the reservoir’s Administration Building.Samples were collected during storm events and were analyzed for total suspended solids(TSS),biochemical oxygen demand(BOD5),ammonia nitrogen(NH3-N),and total phosphorus(TP).The removal efficiencies of both BMP systems were evaluated using the Efficiency Ratio(ER)method based on the event mean concentration(EMC)data.In summary,the pond/wetland treatment train removed 70%–90%of TSS,20%–50%of BOD5,and 30%–70%of TP and NH3-N.The swale removed 50%–90%of TSS,30%–55%of BOD5,–10%–35%of NH3-N,and 25%–70%of TP.For the planter box and biobox,the ranges of removal rates were 70%–90%,20%–50%,and 30%–70%for TSS,BOD5,and ammonia and phosphorus,respectively.Ru ZHANG Wenbin ZHOU Richard FIELD Anthony TAFURI Shaw LYU Keli JIN 2009Frontiers of Environmental Science & Engineering2009,3,3:12
9Predictors and reduction techniques for irreducible reverse intertrochanteric fractures显示文摘Background:Reverse intertrochanteric fractures are usually initially treated with closed reduction.However,sometimes these fractures are not amenable to closed reduction and require open reduction.To date,few studies have been conducted on predictors of and reduction techniques for irreducible reverse intertrochanteric fractures.Therefore,this study aimed to summarize the displacement patterns of irreducible reverse intertrochanteric fractures and corresponding reduction techniques,and explore predictors of irreducibility.Methods:We reviewed 1174 cases of trochanteric fractures treated in our hospital from January 2006 to October 2018,113 of which were reverse intertrochanteric fractures.An irreducible fracture was determined according to intra-operative fluoroscopy imaging after closed manipulation.Fractures were assessed for displacement patterns,radiographic features of irreducibility,and reduction techniques.Logistic regression analysis was performed on potential predictors for irreducibility,including gender,age,body mass index,AO Foundation/Orthopaedic Trauma Association(AO/OTA)classification,and radiographic features.Results:Seventy-six irreducible fractures were identified,accounting for 67%of reverse intertrochanteric fractures.Six patterns of fracture displacement after closed manipulation were identified;the most common pattern was medial displacement and posterior sagging of the femoral shaft relative to the head-neck fragment.Multivariate logistic regression analysis identified three predictors of irreducibility:a medially displaced femoral shaft relative to the head-neck fragment on the anteroposterior(AP)view(odds ratio[OR],8.00;95%confidence interval[CI],3.04–21.04;P<0.001),a displaced lesser trochanter(OR,3.61;95%CI,1.35–9.61;P=0.010),and a displaced lateral femoral wall(OR,2.92;95%CI,1.02–8.34;P=0.046).Conclusions:A high proportion of reverse intertrochanteric fractures are not amenable to closed reduction.Six patterns of fracture displacement after closed manipulation were identified.Different reduction techniques are required for different displacement patterns.Predictors of irreducibility include a medially displaced femoral shaft relative to the head-neck fragment on the AP view,a displaced lesser trochanter,and a displaced lateral femoral wall.These patients warrant special consideration in terms of recognition and management.You-Liang Hao Zhi-Shan Zhang Fang Zhou Hong-Quan Ji Yun Tian Yan Guo Yang Lyu Zhong-Wei Yang Guo-Jin Hou 2019Chinese Medical Journal2019,,21:11
10Prediction of Disc Cutter Life During Shield Tunneling with AI via the Incorporation of a Genetic Algorithm into a GMDH-Type Neural Network显示文摘Disc cutter consumption is a critical problem that influences work performance during shield tunneling processes and directly affects the cutter change decision.This study proposes a new model to estimate the disc cutter life(Hf)by integrating a group method of data handling(GMDH)-type neural network(NN)with a genetic algorithm(GA).The efficiency and effectiveness of the GMDH network structure are optimized by the GA,which enables each neuron to search for its optimum connections set from the previous layer.With the proposed model,monitoring data including the shield performance database,disc cutter consumption,geological conditions,and operational parameters can be analyzed.To verify the performance of the proposed model,a case study in China is presented and a database is adopted to illustrate the excellence of the hybrid model.The results indicate that the hybrid model predicts disc cutter life with high accuracy.The sensitivity analysis reveals that the penetration rate(PR)has a significant influence on disc cutter life.The results of this study can be beneficial in both the planning and construction stages of shield tunneling.Khalid Elbaz Shui-Long Shen Annan Zhou Zhen-Yu Yin Hai-Min Lyu 2021Engineering2021,7,2:10

14Psychophysiological Effects of Bamboo Plants on Adults显示文摘The present study was conducted to clarify the psychophysiological relaxation effects of viewing bamboo on university students. Forty healthy Chinese participants enrolled in this study to clarify the psychophysiological relaxation effects of viewing bamboo. The effects of visual stimulation using a pot both with and without a bamboo were recorded by measuring the student's blood pressure, EEG and STAI. We observed that viewing bamboo plants resulted in significantly lower systolic(female, P < 0.001; male, P < 0.001; P < 0.05) and diastolic(female,P < 0.001; male, P < 0.001; P < 0.05) blood pressures, but no changes in the pulse rate(female, P = 0.09; male, P = 0.07; P > 0.05) were observed. The results of the EEG analysis indicated brainwave variation(all P < 0.05) and lower anxiety scores(P < 0.01) after 3 min of viewing bamboo compared with the control. These findings indicate that visual stimulation with bamboo plants induced psychophysiological relaxation effects on adults.Ahmad Hassan CHEN Qi Bing JIANG Tao LYU Bing Yang LI Nian LI Shu SHANGGUAN Zi Yue LI Yun Ting JUN Zhou Li LUO Qian CHEN Xin Yi WANG Yi Yan ZENG Cheng Cheng YANG Jun Muhammad Sohaib Tahir 2017Biomedical and Environmental Sciences2017,30,11:8

16Spatial and Temporal Evolution of Surface Subsidence in Tianjin from 2015 to 2020 Based on SBAS-InSAR Technology显示文摘Tianjin is one of the inland cities with the most severe cases of subsidence hazard in China.The majority of the existing studies have mainly focused on Beijing-Tianjin-Hebei,and little attention has been given to Tianjin.In addition,these existing studies are short-term investigations,lacking long-term monitoring of surface subsidence.In the present study,we use the Small Baseline Subset Interferometric Synthetic Aperture Radar(SBAS-InSAR)technique to monitor the subsidence process in Tianjin between 2015 and 2020 and reveal its spatial and temporal variation.We divided the 44-view Sentinel-1A image data into three periods to avoid the effect of temporal and spatial decoherence by extracting the surface deformation field in Tianjin.We finally verified the accuracy and reliability of the inversion results using second-order leveling data.Results showed that the correlation coefficient r between the two reached 0.89,and the root mean square error was 4.84 mm/y.Obvious subsidence funnels exist in Tianjin,mainly in the towns of Wangqingtuo and Shengfang.These subsidence funnels have a subsidence deformation rate of-136.2 mm/y and a maximum cumulative settlement of-346.3 mm within the study period.The subsidence area tends to extend to the southwest.The analysis of annual rainfall,groundwater resource extraction,spatial location distribution of industrial areas combined with SBAS-InSAR inversion results indicates that overextraction of groundwater resources is the main cause of land subsidence in the area.Therefore,strict control of groundwater extraction is the main approach to mitigate land subsidence effectively.Lyu ZHOU Yizhan ZHAO Zilin ZHU Chao REN Fei YANG Ling HUANG Xin LI 2022Journal of Geodesy and Geoinformation Science2022,5,1:8
17Zika virus infection induces RNAi-mediated antiviral immunity in human neural progenitors and brain organoids显示文摘The re-emergence of Zika virus(ZIKV)in the Western Hemisphere has resulted in global public health crisis since 2015.ZIKV preferentially infects and targets human neural progenitor cells(hNPCs)and causes fetal microcephaly upon maternal infection.hNPCs not only play critical roles during fetal brain development,but also persist in adult brain throughout life.Yet the mechanism of innate antiviral immunity in hNPCs remains largely unknown.Here,we show that ZIKV infection triggers the abundant production of virus-derived small interfering RNAs in hNPCs,but not in the more differentiated progenies or somatic cells.Ablation of key RNAi machinery components significantly enhances ZIKV replication in hNPCs.Furthermore,enoxacin,a broad-spectrum antibiotic that is known as an RNAi enhancer,exerts potent anti-ZIKV activity in hNPCs and other RNAi-competent cells.Strikingly,enoxacin treatment completely prevents ZIKV infection and circumvents ZIKV-induced microcephalic phenotypes in brain organoid models that recapitulate human fetal brain development.Our findings highlight the physiological importance of RNAi-mediated antiviral immunity during the early stage of human brain development,uncovering a novel strategy to combat human congenital viral infections through enhancing RNAi.Yan-Peng Xu Yang Qiu Boya Zhang Guilai Chen Qi Chen Miao Wang Fan Mo Jiuyue Xu Jin Wu Rong-Rong Zhang Meng-Li Cheng Na-Na Zhang Bao Lyu Wen-Liang Zhu Meng-Hua Wu Qing Ye Da Zhang Jiang-Hong Man Xiao-Feng Li Jie Cui Zhiheng Xu Baoyang Hu Xi Zhou Cheng-Feng Qin 2019Cell Research2019,29,4:8
18The origin, diversification and adaptation of a major mangrove clade (Rhizophoreae) revealed by whole-genome sequencing显示文摘Mangroves invade some very marginal habitats for woody plants—at the interface between land and sea.Since mangroves anchor tropical coastal communities globally, their origin, diversification and adaptation are of scientific significance, particularly at a time of global climate change. In this study, a combination of single-molecule long reads and the more conventional short reads are generated from Rhizophora apiculata for the de novo assembly of its genome to a near chromosome level. The longest scaffold, N50 and N90 for the R. apiculata genome, are 13.3 Mb, 5.4 Mb and 1.0 Mb, respectively. Short reads for the genomes and transcriptomes of eight related species are also generated. We find that the ancestor of Rhizophoreae experienced a whole-genome duplication ~70 Myrs ago, which is followed rather quickly by colonization and species diversification. Mangroves exhibit pan-exome modifications of amino acid(AA) usage as well as unusual AA substitutions among closely related species. The usage and substitution of AAs, unique among plants surveyed, is correlated with the rapid evolution of proteins in mangroves. A small subset of these substitutions is associated with mangroves' highly specialized traits(vivipary and red bark) thought to be adaptive in the intertidal habitats. Despite the many adaptive features, mangroves are among the least genetically diverse plants, likely the result of continual habitat turnovers caused by repeated rises and falls of sea level in the geologically recent past. Mangrove genomes thus inform about their past evolutionary success as well as portend a possibly difficult future.Shaohua Xu Ziwen He Zhang Zhang Zixiao Guo Wuxia Guo Haomin Lyu Jianfang Li Ming Yang Zhenglin Du Yelin Huang Renchao Zhou Cairong Zhong David E.

19Non‑Magnetic Bimetallic MOF‑Derived Porous Carbon‑Wrapped TiO2/ ZrTiO4 Composites for Efficient Electromagnetic Wave Absorption显示文摘Modern communication technologies put forward higher requirements for electromagnetic wave(EMW)absorption materials.Metal-organic framework(MOF)derivatives have been widely concerned with its diverse advantages.To break the mindset of magneticderivative design,and make up the shortage of monometallic non-magnetic derivatives,we first try non-magnetic bimetallic MOFs derivatives to achieve efficient EMW absorption.The porous carbon-wrapped TiO2/ZrTiO4 composites derived from PCN-415(TiZr-MOFs)are qualified with a minimum reflection loss of−67.8 dB(2.16 mm,13.0 GHz),and a maximum effective absorption bandwidth of 5.9 GHz(2.70 mm).Through in-depth discussions,the synergy of enhanced interfacial polarization and other attenuation mechanisms in the composites is revealed.Therefore,this work confirms the huge potentials of nonmagnetic bimetallic MOFs derivatives in EMW absorption applications.Jing Qiao Xue Zhang Chang Liu Longfei Lyu Yunfei Yang Zhou Wang Lili Wu Wei Liu Fenglong Wang Jiurong Liu 2021Nano-Micro Letters2021,13,5:7
20Pregnane receptor gene polymorphisms,pathogenic bacteria distribution and drug sensitivity,and TCM dyndrome differentiation in patients with cholelithiasis显示文摘Objective:To investigate the distribution of pathogens and drug resistance in bile and the association between the pregane X receptor(PXR) gene polymorphisms,traditional Chinese medicine(TCM) syndromes and the risk of cholesterol gallstone disease(CGD).Methods:A total of 392 samples were enrolled in this study from January 2014 to February 2015.among which 192 patients were with CGD.and 200 samples were healthy.Strains were isolated and susceptibility testing was the disk diffusion method susceptibility testing.The patients were divided into hepatochlic hygropyrexia.stagnation of liver-qi.and the accumulation of damp.The PXR gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism.The association between the PXR gene polymorphisms and the risk of CGD was examined by logistic regression analysis.Results:A total of 192 cases were detected in 230 of bile culture pathogens,including Grain-negative bacteria 133(57.83%),Gram-positive bacteria76(33.04%),and fungi 21(9.13%).The top five pathogens were Escherichia coli,Klebsiella pneumoniae.Enterococcus faecalis,Candida albicans,and Enterococcus feces,ot which 110 cases was of single infection.48 cases of mixed infection of two strains,eight cases of mixed infection of three bacteria.Among 59 Escherichia coli,the yield extended-spectrum beta-laetamases had 40(67.80%).The hepatochlic hygropyrexia was the most TCM syndrome,followed by stagnation of liver-qi.and the accumulation of damp was least.Different pathogens and the rs6785049 genotypes distributed differently in cholelithiasis patients with different TCM syndromes(P<0.05).In hepatochlic hygropyrexia patients the Gram-negative bacteria was most.There was significant differences between CGD group and control group in rs6785049(P<0.001).Comparison with wild-type portable GG.GA genotype increased the risk of the occurrence of gallstones(OR=0.40.95%CI:0.16-0.79);likewise,carrying the GA + AA genotype also increased the risk(OR=0.38,95%CI:0.19-0.81).There was no significant differences in rs2276707,rs3814055 site polymorphic loci alleles in CGD group and control group.Conclusions:In the treatment of cholelithiasis,bile samples should be collected for bacterial culture and sensitivity test,and drugs should be strictly chosen based on the results.The rs6785049 polymorphisms in PXR gene may increase the risk of gallstones ontogeny,and gallstones can he early detected and prevented by detecting genotypes.rs6785049 polymorphisms in PXR gene may has relationship with TCM syndromes.Yi-Qiang Xie Jing-Zhe Zhang Hua Zhang Lei Peng Shuang Zhou Li-Zhuo Li Bang-Jiang Fang Chuan-Zhu Lyu 2016Asian Pacific Journal of Tropical Medicine2016,9,4:7
