| 1 | The effect of hematoma puncture drainage before decompressive craniectomy on the prognosis of hypertensive intracerebral hemorrhage with cerebral hernia at a high altitude显示文摘Purpose:Rapid decompressive craniectomy(DC)was the most effective method for the treatment of hypertensive intracerebral hemorrhage(HICH)with cerebral hernia,but the mortality and disability rate is still high.We suspected that hematoma puncture drainage(PD)+DC may improve the therapeutic effect and thus compared the combined surgery with DC alone.Methods:From December 2013 to July 2019,patients with HICH from Linzhi,Tibet and Honghe,Yunnan Province were retrospectively analyzed.The selection criteria were as follows:(1)altitude≥1500 m;(2)HICH patients with cerebral hernia;(3)Glascow coma scale score of 4-8 and time from onset to admission≤3 h;(4)good liver and kidney function;and(5)complete case data.The included patients were divided into DC group and PD+DC group.The patients were followed up for 6 months.The outcome was assessed by Glasgow outcome scale(GOS)score,Kaplan-Meier survival curve and correlation between time from admission to operation and prognosis.A good outcome was defined as independent(GOS score,4-5)and poor outcome defined as dependent(GOS score,3-1).All data analyses were performed using SPSS 19,and comparison between two groups was conducted using separatet-tests or Chi-square tests.Results:A total of 65 patients was included.The age ranged 34-90 years(mean,63.00±14.04 years).Among them,31 patients had the operation of PD+DC,whereas 34 patients underwent DC.The two groups had no significant difference in the basic characteristics.After 6 months of follow-up,in the PD+DC group there were 8 death,4 vegetative state,4 severe disability(GOS score 1-3,poor outcome 51.6%);8 moderate disability,and 7 good recovery(GOS score 4-5,good outcome 48.4%);while in the DC group the result was 15 death,6 vegetative state,5 severe disability(poor outcome 76.5%),4 moderate disability and 4 good recovery(good outcome 23.5%).The GOS score and good outcome were significantly less in DC group than in PD+DC group(Z=-1.993,p=0.046;χ2=4.38,p=0.043).However,there was no significant difference regarding the survival curve between PD+DC group and DC group.The correlation between the time from admission to operation and GOS at 6 months(r=-0.41,R2=0.002,p=0.829)was not significant in the PD+DC group,but significant in the DC group(r=-0.357,R2=0.128,p=0.038).Conclusion:PD+DC treatment can improve the good outcomes better than DC treatment for HICH with cerebral hernia at a high altitude. | Lin-Jie Wei Chi Lin Xing-Sen Xue Guo-Dong Dun Jian-Bo Zhang Yan-Xiang Tong Jia-Xiong Wang Shi-Ji Yang Ling Wang Zhi Chen Hua Feng Gang Zhu | 2021 | Chinese Journal of Traumatology2021，24，6： | 11 |
| 2 | Advances in BeiDou Navigation Satellite System(BDS)and satellite navigation augmentation technologies显示文摘Several noteworthy breakthroughs have been made with the BeiDou Navigation Satellite System(BDS)and other global navigation satellite systems as well as the associated augmentation systems,such as the commissioning of the BDS-3 preliminary system and the successful launch of the first BDS-3 GEO satellite which carries the satellite-based augmentation payload.Presently,BDS can provide basic services globally,and its augmentation system is also being tested.This paper gives an overview of BDS and satellite navigation augmentation technologies.This overview is divided into four parts,which include the system segment technologies,satellite segment technologies,propagation segment technologies,and user segment technologies.In each part,these technologies are described from the perspectives of preliminary information,research progress,and summary.Moreover,the significance and progress of the BeiDou Satellite-based Augmentation System(BDSBAS),low earth orbit augmentation,and the national BeiDou ground-based augmentation system are presented,along with the airborne-based augmentation system.Furthermore,the conclusions and discussions covering popular topics for research,frontiers in research and development,achievements,and suggestions are listed for future research. | Rui Li Shuaiyong Zheng Ershen Wang Jinping Chen Shaojun Feng Dun Wang Liwen Dai | 2020 | Satellite Navigation2020，1，1： | 9 |

| 4 | Dynamic expression of Slit1–3 and Robo1–2 in the mouse peripheral nervous system after injury显示文摘The Slit family of axon guidance cues act as repulsive molecules for precise axon pathfinding and neuronal migration during nervous system development through interactions with specific Robo receptors.Although we previously reported that Slit1–3 and their receptors Robo1 and Robo2 are highly expressed in the adult mouse peripheral nervous system,how this expression changes after injury has not been well studied.Herein,we constructed a peripheral nerve injury mouse model by transecting the right sciatic nerve.At 14 days after injury,quantitative real-time polymerase chain reaction was used to detect mRNA expression of Slit1–3 and Robo1–2 in L4–5 spinal cord and dorsal root ganglia,as well as the sciatic nerve.Immunohistochemical analysis was performed to examine Slit1–3,Robo1–2,neurofilament heavy chain,F4/80,and vimentin in L4–5 spinal cord,L4 dorsal root ganglia,and the sciatic nerve.Co-expression of Slit1–3 and Robo1–2 in L4 dorsal root ganglia was detected by in situ hybridization.In addition,Slit1–3 and Robo1–2 protein expression in L4–5 spinal cord,L4 dorsal root ganglia,and sciatic nerve were detected by western blot assay.The results showed no significant changes of Slit1–3 or Robo1–2 mRNA expression in the spinal cord within 14 days after injury.In the dorsal root ganglion,Slit1–3 and Robo1–2 mRNA expression were initially downregulated within 4 days after injury;however,Robo1–2 mRNA expression returned to the control level,while Slit1–3 mRNA expression remained upregulated during regeneration from 4–14 days after injury.In the sciatic nerve,Slit1–3 and their receptors Robo1–2 were all expressed in the proximal nerve stump;however,Slit1,Slit2,and Robo2 were barely detectable in the nerve bridge and distal nerve stump within 14 days after injury.Slit3 was highly ex-pressed in macrophages surrounding the nerve bridge and slightly downregulated in the distal nerve stump within 14 days after injury.Robo1 was upregulated in vimentin-positive cells and migrating Schwann cells inside the nerve bridge.Robo1 was also upregulated in Schwann cells of the distal nerve stump within 14 days after injury.Our findings indicate that Slit3 is the major ligand expressed in the nerve bridge and distal nerve stump during peripheral nerve regeneration,and Slit3/Robo signaling could play a key role in peripheral nerve repair after injury.This study was approved by Plymouth University Animal Welfare Ethical Review Board (approval No.30/3203) on April 12,2014. | Bing Chen Lauren Carr Xin-Peng Dun | 2020 | Neural Regeneration Research2020，15，5： | 6 |
| 5 | PA1b, a plant peptide, induces intracellular [Ca^(2+)] in- crease via Ca^(2+) influx through the L-type Ca^(2+) channel and triggers secretion in pancreatic β cells显示文摘Using alginic acid to adsorb polypeptides at pH 2.7, we isolated a peptide pea albumin 1b (PA1b) from pea seeds. The PA1b is a single chain peptide consisting of 37 amino acid residues with 6 cysteines which constitutes the cystine-knot structure. Using microfluorometry and patch clamp techniques, we found that PA1b significantly elevated the intracellular calcium level ([Ca2+ ]i) and elicited membrane capacitance increase in the primary rat pancreatic β cells. The PA1b effect on [Ca2+]i elevation was abolished in the absence of extracellular Ca2+ or in the presence of L-type Ca2+ channel blocker, ni- modipine. Interestingly, we found that PA1b significantly depolarized membrane potential, which could lead to the opening of voltage-dependent L-type Ca2+ channels and influx of extracellular Ca2+, and then evoke robust secretion. In this study we identified the plant peptide PA1b which is capable of affecting the excitability and function of mammalian pancreatic β cell. | HU ZhiTao1, DUN XinPeng1, ZHANG Ming1, ZHU HongLiang1, XIE Li1, WU ZhengXing1, CHEN ZhengWang1 & XU Tao1,2 1 Joint Laboratory of Institute of Biophysics and Huazhong University of Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China 2 National Laboratory of Biomacromolecules, Institute of Biophysics, Chinese Academy of Sciences, Beijing 100101, China. | 2007 | Science China(Life Sciences)2007，50，3： | 5 |

| 7 | Effect of toll-like receptor 3 agonist poly I:C on intestinal mucosa and epithelial barrier function in mouse models of acute colitis显示文摘AIM To investigate potential effects of poly I:C on mucosal injury and epithelial barrier disruption in dextran sulfate sodium(DSS)-induced acute colitis.METHODS Thirty C57BL/6 mice were given either regular drinking water(control group) or 2%(w/v) DSS drinking water(model and poly I:C groups) ad libitum for 7 d. Poly I:C was administrated subcutaneously (20 μg/mouse) 2 h prior to DSS induction in mice of the poly I:C group. Severity of colitis was evaluated by disease activity index, body weight, colon length, histology and myeloperoxidase (MPO) activity, as well as the production of proinflammatory cytokines, including tumor necrosis factor-α(TNF-α), interleukin 17(IL-17) and interferon-γ (IFN-γ). Intestinal permeability was analyzed by the fluorescein isothiocyanate labeleddextran (FITC-D) method. Ultrastructural features of the colon tissue were observed under electron microscopy. Expressions of tight junction(TJ) proteins, including zo-1, occludin and claudin-1, were measured by immunohistochemistry/immunofluorescence, Western blot and real-time quantitative polymerase chain reaction(RT-qPCR).RESULTS DSS caused significant damage to the colon tissue in the model group. Administration of poly I:C dramatically protected against DSS-induced colitis, as demonstrated by less body weight loss, lower disease activity index score, longer colon length, colonic MPO activity, and improved macroscopic and histological scores. It also ameliorated DSS-induced ultrastructural changes of the colon epithelium, as observed under scanning electron microscopy, as well as FITC-D permeability. The m RNA and protein expressions of TJ protein, zo-1, occludin and claudin-1 were also found to be significantly enhanced in the poly I:C group, as determined by immunohistochemistry/immunofluorescence, Western blot and RT-q PCR. By contrast, poly I:C pretreatment markedly reversed the DSS-induced up-regulated expressions of the inflammatory cytokines TNF-α, IL-17 and IFN-γ.CONCLUSION Our study suggested that poly I:C may protect against DSS-induced colitis through maintaining integrity of the epithelial barrier and regulating innate immune responses, which may shed light on the therapeutic potential of poly I:C in human colitis. | Hong-Wei Zhao Yue-Hong Yue Hua Han Xiu-Li Chen Yong-Gang Lu Ji-Min Zheng Hong-Tao Hou Xiao-Meng Lang Li-Li He Qi-Lu Hu Zi-Qian Dun | 2017 | World Journal of Gastroenterology2017，23，6： | 5 |
| 8 | Development of highly glyphosate-tolerant tobacco by coexpression of glyphosate acetyltransferase gat and EPSPS G2-aroA genes显示文摘The widely used herbicide glyphosate targets 5-enolpyruvylshikimate-3-phosphate synthase(EPSPS).Glyphosate acetyltransferase(GAT)effectively detoxifies glyphosate by N-acetylation.With the aim of identifying a new strategy for development of glyphosate-tolerant crops,the plant expression vector pG2-GAT harboring gat and G2-aroA(encoding EPSPS)has been transformed into tobacco(Nicotiana tabacum)to develop novel plants with higher tolerance to glyphosate.Results from Southern and Western blotting analyses indicated that the target genes were integrated into tobacco chromosomes and expressed effectively at the protein level.Glyphosate tolerance was compared among transgenic tobacco plants containing gat,G2-aroA,or both genes.Plants containing both gat and G2-aroA genes were the most glyphosate-tolerant.This study has shown that a combination of different strategies may result in higher tolerance in transgenic crops,providing a new approach for development of glyphosate-tolerant crops. | Baoqing Dun Xujing Wang Wei Lu Ming Chen Wei Zhang Shuzhen Ping Zhixing Wang Baoming Zhang Min Lin | 2014 | The Crop Journal2014，2，Z1： | 4 |
| 9 | Broadband, sensitive and spectrally distinctive SnS_(2) nanosheet/PbS colloidal quantum dot hybrid photodetector显示文摘Photodetectors convert photons into current or voltage outputs and are thus widely used for spectroscopy,imaging and sensing.Traditional photodetectors generally show a consistent-polarity response to incident photons within their broadband responsive spectrum.Here we introduced a new type of photodetector employing SnS_(2) nanosheets sensitized with PbS colloidal quantum dots(CQDs)that are not only sensitive(~105AW−1)and broadband(300–1000 nm)but also spectrally distinctive,that is,show distinctive(positive or negative)photoresponse toward incident photons of different wavelengths.A careful mechanism study revealed illumination-modulated Schottky contacts between SnS_(2) nanosheets and Au electrodes,altering the photoresponse polarity toward incident photons of different wavelengths.Finally,we applied our SnS_(2) nanosheet/PbS CQDs hybrid photodetector to differentiate the color temperature of emission from a series of white light-emitting diodes(LEDs),showcasing the unique application of our novel photodetectors. | Liang Gao Chao Chen Kai Zeng Cong Ge Dun Yang Haisheng Song Jiang Tang | 2016 | Light(Science & Applications)2016，5，1： | 4 |
| 10 | Mitochondrial DNA T7719G in tRNA-Lys gene affects litter size in Small-tailed Han sheep显示文摘Background: In farm animals, mitochondrial DNA(mtDNA) effect on economic performance remains hot-topic for breeding and genetic selection. Here, 53 maternal lineages of Small-tailed Han sheep were used to investigate the association of mitochondrial DNA variations and the lambing litter size.Results: Sequence sweeping of the mitochondrial coding regions discovered 31 non-synonymous mutations, and the association study revealed that T7719G in mt DNA t RNA-Lys gene was associated with litter size(P < 0.05),manifesting 0.29 lambs per litter between the G and T carriers. Furthermore, using the mixed linear model, we assayed the potential association of the ovine litter size and haplogroups and multiple-level mtDNA haplotypes,including general haplotypes, assembled haplotypes of electron transport chain contained sequences(H-ETC),mitochondrial respiratory complex contained sequences(H-MRC) and mitochondrial genes(H-gene, including polypeptide-coding genes, rRNA genes and tRNA genes). The strategy for assembled mitochondrial haplotypes was proposed for the first time in mtDNA association analyses on economic traits, although none of the significant relations could be concluded(P > 0.05). In addition, the nuclear major gene BMPR1B was significantly correlated with litter size in the flock(P < 0.05), however, did not interact with mtDNA T7719G mutation(P > 0.05).Conclusions: Our results highlight mutations of ovine mitochondrial coding genes, suggesting T7719G in tRNA-Lys gene be a potentially useful marker for selection of sheep litter size. | Xiaoyong Chen Dan Wang Hai Xiang Weitao Dun Dave O.H.Brahi Tao Yin Xingbo Zhao | 2017 | Journal of Animal Science and Biotechnology2017，8，3： | 4 |
| 11 | Giant magnetoimpedance effect in stress-joule-heated Co-based amorphous ribbons显示文摘Co-based Co63Fe4B22.4Si5.6Nb5 amorphous ribbons with a width of 150 μm and a thickness of 50 μm were prepared by single-roller melt-spinning process.The giant magneto-impedance(GMI) effect of the stress-joule-heated ribbons under applied tensile stress ranging from 37 to 148 MPa was investigated.Experimental results show that the spectra of GMI ratio vs.external direct current(dc) field(Hex) of the samples changes dramatically with annealing tension() and driving frequency.The single-peak(SP) GMI curve with maximum GMI ratio of 260% and magnetic field sensitivity of 52%/Oe was obtained in the sample applied tensile stress of 74 MPa at frequency of 3.6 MHz.A three-peak behaviour appeared in the samples under σ of 111 and 148 MPa.The uncommon three-peak behaviour was attributed to several factors,which effectively originated from the balance between domain-wall movement and magnetization rotation. | CHEN ShuangQin MAN QiKui DUN ChaoChao SHEN BaoLong | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，12： | 3 |

| 14 | Estimating Seismic Intensity Maps of the 2021 Mw 7.3 Madoi,Qinghai and Mw 6.1 Yangbi,Yunnan,China Earthquakes显示文摘This study focuses on rapidly determining seismic intensity maps of earthquakes because it offers fundamental information for effective emergency rescue and subsequent scientific research,and remains challenging to accurately determine seismic intensity map in regions with sparse instrumental observations.Here we applied a novel method that consisted of array technology(backprojection),ground-motion prediction equations,and site corrections,to estimate the seismic intensity maps of the 2021 Mw 7.3 Madoi,Qinghai and the Mw 6.1 Yangbi,Yunnan,China earthquakes.We used seismic data recorded at European stations to back-project the source processes of the 2021 Mw7.3 Madoi,Qinghai and the Mw 6.1 Yangbi,Yunnan,China earthquakes.The back-projected energy radiations were then used as subevents or used to define the fault geometry.Summing the contributions of each subevent or estimating the shortest distances from each site to the rupture fault,we obtained the ground motion(PGA and PGV)for each site under rock site conditions.The estimated ground motions were corrected at each site for local site amplification according to the Vs30 database.Our estimated seismic intensity maps and field reports showed high similarity,which further validated the effectiveness of the novel approach,and pushed the limit of earthquake size down to~M 6.Such efforts would substantially help in the fast and accurate evaluation of earthquake damage,and precise rescue efforts. | Wenkai Chen Dun Wang Can Zhang Qiang Yao Hongjun Si | 2022 | Journal of Earth Science2022，33，4： | 2 |

| 16 | Three Super Active Regions in the Descending Phase of Solar Cycle 23显示文摘We analyze the magnetic configurations of three super active regions,NOAA 10484, 10486 and 10488, observed by the Huairou Multi-Channel Solar Telescope (MCST) from 2003 October 18 to November 4. Many energetic phenomena,such as flares (including a X-28 flare) and coronal mass ejections (CMEs), occurred during this period. We think that strong shear and fast emergence of magnetic flux are the main causes of these events. The question is also of great interest why these dramatic eruptions occurred so close together in the descending phase of the solar cycle. | Hong-Qi Zhang, Xing-Ming Bao, Yin Zhang, Ji-Hong Liu, Shu-Dong Bao, Yuan-Yong Deng, Wei Li, Jie Chen, Jin-Ping Dun, Jiang-Tao Su, Juan Guo, Xiao-Fan Wang, Ke-Liang Hu, Gang-Hua Lin and Dong-Guang WangNational Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012 | 2003 | Chinese Journal of Astronomy and Astrophysics2003，3，6： | 2 |
| 17 | Effect of Plasticizers on Properties of Rice Straw Fiber Film显示文摘In order to improve the properties of rice straw fiber film, one factor contrast test method was employed. Plasticizer type was chosen as input variable, dry tension strength and elongation, wet tension strength and elongation, bursting strength and tearing strength were chosen as indexes. The results showed that there were significant differences among the means of dry tension strength, dry elongation and bursting strength of different plasticizers; there were not significant differences among the means of wet tension strength, wet elongation and tearing strength of different plasticizers; for dry tension strength and elongation, glycerol had a significant difference with sorbitol and PEG, no significant difference was observed between sorbitol and PEG, dry tension strength added glycerol had been reduced 6.8% compared with that added sorbitol, reduced 9.5% compared with that added PEG; elongation had been improved 6.1% and 9.4%, respectively; for bursting strength, sorbitol had a significant difference with glycerol and PEG, no significant difference was observed between glycerol and PEG; bursting strength added glycerol and added PEG had been improved 6.9% and 5.6%, respectively compared with that of the added sorbitol. The results provided a theoretical reference for further improving the straw fiber film manufacturing process. | Chen Hong-rui Chen Hai-tao Liu Shuang Dun Guo-qiang Zhang Ying | 2014 | Journal of Northeast Agricultural University(English Edition)2014，21，4： | 2 |
| 18 | Tailoring spin mixtures by ion-enhanced Maxwell magnetic coupling in colortunable organic electroluminescent devices显示文摘In this work,we show that the spin dynamics of excitons can be dramatically altered by Maxwell magnetic field coupling,together with an ion-enhanced,low-internal-splitting-energy organic semiconducting emitter.By employing a unique,alternating current(AC)-driven organic electroluminescent(OEL)device architecture that optimizes this magnetic field coupling,almost complete control over the singlet-to-triplet ratio(from fluorescent to phosphorescent emission in a single device)is realized.We attribute this spin population control to magnetically sensitive polaron–spin pair intersystem crossings(ISCs)that can be directly manipulated through external driving conditions.As an illustration of the utility of this approach to spin-tailoring,we demonstrate a simple hybrid(double-layer)fluorescence–phosphorescence(F–P)device using a polyfluorene-based emitter with a strong external Zeeman effect and ion-induced long carrier diffusion.Remarkable control over de-excitation pathways is achieved by controlling the device-driving frequency,resulting in complete emission blue–red color tunability.Picosecond photoluminescence(PL)spectroscopy directly confirms that this color control derives from the magnetic manipulation of the singlet-totriplet ratios.These results may pave the way to far more exotic organic devices with magnetic-field-coupled organic systems that are poised to usher in an era of dynamic spintronics at room temperature. | Junwei Xu Yue Cui Gregory M.Smith Peiyun Li Chaochao Dun Linqi Shao Yang Guo Hongzhi Wang Yonghua Chen David L.Carroll | 2018 | Light(Science & Applications)2018，7，1： | 2 |
