| 3 | Heat induces adenosine triphosphate release from mast cells in vitro:a putative mechanism for moxibustion显示文摘OBJECTIVE:To investigate the role of adenosine triphosphate(ATP) purinergic signaling in mast cells(MCs) modulated by heat to further understand the molecular mechanisms of moxibustion.METHODS:Skin temperatures induced by monkshood cake moxibustion were evaluated by measuring the Neiguan acupoint(PC 6) from 31 participants with a digital thermocouple thermometer.Temperatures of 43 ℃ and 52 ℃ were applied to cultured human leukemia mast cell line HMC-1 in vitro.Calcium fluorescence was applied to detect intracellular Ca^(2+)([Ca^(2+)]_i).Extracellular ATP contents were measured by luciferin-luciferase assay.RESULTS:Maximum skin temperatures mostly ranged from 40-45 ℃,but some reached up to50 ℃.Both 43 ℃,and 52 ℃ induced MC degranulation,which was accompanied by an increase in[Ca^(2+)]_i and ATP release.Complexing extracellular Ca^(2+) with 5 mM ethylene glycol-bis(β-aminoethyl ether)-N,N,N',N'-tetraacetic acid(EGTA) inhibited the noxious heat-induced elevation of[Ca^(2+)]_i and prevented the enhanced ATP secretion by those cells at 52℃ but not 43 ℃.CONCLUSION:Monkshood cake moxibustion can generate heat sufficient to trigger cellular events of MCs,including degranulation,[Ca^(2+)]_i elevation,and ATP release,suggesting that purinergic signals originating from MCs are possibly the initiating response of acupoints to moxibustion. | Hu Lei Wang Lina Wei Jianzi Ryszard Grygorczyk Shen Xueyong Wolfgang Schwarz | 2015 | Journal of Traditional Chinese Medicine2015，35，3： | 12 |
| 4 | Endovascular treatment with or without intravenous alteplase for acute ischaemic stroke due to basilar artery occlusion显示文摘Background and purpose It remains controversial if endovascular treatment(EVT)can improve the outcome of patients with acute basilar artery occlusion(BAO).This study aims to compare the functional outcomes between EVT with and without intravenous thrombolysis(IVT)first in patients who had acute ischaemic stroke(AIS)due to BAO.Methods Patients who had AIS with BAO who underwent EVT within 24 hours of onset were enrolled in this multicentre cohort study,and the efficacy and safety were compared between IVT+EVT and direct EVT.The primary outcome was 90-day functional independence.All outcomes were assessed with adjusted OR(aOR)from the multivariable logistic regression.In addition,a meta-analysis was performed on all recently published pivotal studies on functional independence after EVT in patients with BAO.Results Of 310 enrolled patients with BAO,241(78%)were treated with direct EVT and 69(22%)with IVT+EVT.Direct EVT was associated with a worse functional outcome(aOR,0.46(95%CI 0.24 to 0.85),p=0.01).IVT+EVT was associated with a lower percentage of patients who needed≥3 passes of stent retriever(10.14%vs 20.75%).The meta-analysis regression revealed a potential positive correlation between bridging with IVT first and functional independence(r=0.14(95%CI 0.05 to 0.24),p<0.01).Conclusions This study showed that compared with direct EVT,EVT with IVT first was associated with better functional outcomes in patients with BAO treated within 24 hours of onset.The meta-analysis demonstrated similar favourable efficacy of IVT first followed by EVT in patients with BAO. | Ximing Nie David Wang Yuehua Pu Yufei Wei Qixuan Lu Hongyi Yan Xin Liu Lina Zheng Jingyi Liu Xinxuan Yang Yarong Ding Dacheng Liu Wanying Duan Zhe Zhang Zhonghua Yang Miao Wen Weibin Gu Xinyi Hou Xinyi Leng Yuesong Pan Zhongrong Miao Liping Liu | 2022 | Stroke & Vascular Neurology2022，7，3： | 10 |
| 5 | High-performance PVDF-HFP based gel polymer electrolyte with a safe solvent in Li metal polymer battery显示文摘Poly(vinylidenefluoride-co-hexafluoropropylene)(PVDF-HFP)based gel polymer electrolytes are widely studied owing to their electrochemical stability and high dielectric constant.However,most gel polymer electrolytes show unsatisfied safety and interface compatibility due to excessive absorption of volatile and flammable liquid solvents.Herein,by using a safe solvent(N-methyl-2-pyrrolidone)with higher boiling(203℃)and flash points(95℃),we initiatively fabricate a flexible PVDF-HFP based gel polymer electrolyte.The obtained gel polymer electrolyte demonstrates a high ionic conductivity of 7.24×10^−4 S cm−1,an electrochemical window of 5.2 V,and a high lithium transference number of 0.57.As a result,the synthesized polymer electrolyte exhibits a capacity retention of 70%after 500 cycles at 0.5 C,and a discharge capacity of 86 mAh g−1 even at a high current rate of 10 C for LiFePO4 based Li metal batteries.Moreover,a stable Li plating/stripping for more than 500 h is achieved under 0.1 mAh at both room temperature and 70℃.Our results indicate that the PVDF-HFP polymer electrolyte is promising for manufacturing safe and high-performance Li metal polymer batteries. | Jing Jie Yulong Liu Lina Cong Bohao Zhang Wei Lu Xinming Zhang Jun Liu Haiming Xie Liqun Sun | 2020 | Journal of Energy Chemistry2020，29，10： | 10 |

| 7 | Fate of secondary effluent dissolved organic matter during soil-aquifer treatment显示文摘The reduction of mass and trihalomethane formation potential (THMFP) of dissolved organic matter (DOM) and its fractions from secondary effluent during laboratory-scale soil-aquifer treatment (SAT) soil columns were studied. Reduction in dissolved organic carbon (DOC), absorbance of ultraviolet light at 254 nm (UV-254), biodegradable dissolved organic carbon (BDOC) and nonbiodegradable dis- solved organic carbon (NBDOC) for the bulk DOM averaged 72.35%, 53.98%, 97.49% and 35.33% across the soil columns, respectively. Using XAD-8 and XAD-4 resins, DOM was fractionated into 3 fractions: hydrophobic acid (HPO-A), transphilic acid (TPI-A) and hydrophilic fraction (HPI). HPO-A was removed by 61.06%, TPI-A by 54.86% and HPI by 74.95% as DOC as a consequence of the laboratory-scale SAT, respectively. The reduction of THMFP from HPO-A, TPI-A and HPI was 27.24%, 26.24% and 36.08%, respectively. Proton nuclear magnetic resonance (1H-NMR) spectra revealed that the HPO-A isolated from the secondary effluent contained more aromatic functional groups than the corresponding TPI-A. Fourier-transform infrared (FT-IR) spectrum analysis illustrated that TPI-A had decreased hydrocarbon and increased aromatics content in the SAT columns. Specific ultraviolet light absorbance (SUVA) and specific THMFP for each DOM fraction increased across the soil columns and HPI exhibited greater increase in both than HPO-A and TPI-A. The most problematic THM precursor was found to be HPO-A with its high quantity present in recharged water and high chlorine reactivity. | XUE Shuang ZHAO QingLiang WEI LiangLiang WANG LiNa LIU ZhiGang | 2007 | Chinese Science Bulletin2007，52，18： | 8 |
| 8 | A 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://gffzzc750bc0108fa4044sv55ofbqp56fk6po9.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 | 2018 | Molecular Plant2018，11，11： | 7 |

| 10 | Study of Krypton Laser-Induced Choroidal Neovascularization in a Guinea Pig Model of High Anisometropia显示文摘Purpose:To investigate the association between high anisometropia and the area of choroidal neovascularization (CNV) induced by krypton laser in guinea pigs and better understand the pathogenesis and prevention of myopic CNV. Methods:.Nine 3-week old male guinea pigs with anisometropia > 6.00D were randomly assigned to three groups according to examination date after laser photocoagulation (7d, 14d and 28d). All animals underwent refraction. The eye with higher myopia was used as the experimental eye, and the other as the control eye..All eyes received repeated multi-wavelength krypton laser photocoagulation treatments (wavelength: 532 nm; laser power: 400 mW; spot diameter: 50 μm; exposure time: 0.1s). Fundus photography and indocyanine green angiography (ICGA) were performed. Afterwards, the animals were sacrificed immediately,.and the eyes were enucleated and processed for histopathologic examination and flat mounts. Results: CNV appeared at 7d after laser treatment. The area of CNV peaked at 14d, and decrease in area and the presence of scarring was noted at 28 d..CNV was present in 66.7% of eyes by ICGA at 14 d..CNV could be observed under light microscopy at all three time points..At 14 d,.flat mount showed the neovascular plexus around the lesion. Semi-quantitative analysis revealed that the area of CNV in treated eyes was greater than that of control eyes. Conclusion:.Since the mechanism of CNV in this study resembles that of CNV in pathological myopia, this model can be used to investigate the etiology, pathogenesis and treatment of CNV in pathological myopia. | Jianghui Wang Wei Jiang Zefeng Kang Lina Liang Xiaoman Liu Nannan Tian Qing Zhang | 2012 | Eye Science2012，27，2： | 4 |
| 11 | Nasal delivery of broadly neutralizing antibodies protects mice from lethal challenge with SARS-CoV-2 delta and omicron variants显示文摘Multiple new variants of severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)have constantly emerged,as the delta and omicron variants,which have developed resistance to currently gained neutralizing antibodies.This highlights a critical need to discover new therapeutic agents to overcome the variants mutations.Despite the availability of vaccines against coronavirus disease 2019(COVID-19),the use of broadly neutralizing antibodies has been considered as an alternative way for the prevention or treatment of SARS-Co V-2 variants infection.Here,we show that the nasal delivery of two previously characterized broadly neutralizing antibodies(F61 and H121)protected K18-h ACE2 mice against lethal challenge with SARS-Co V-2 variants.The broadly protective efficacy of the F61 or F61/F121 cocktail antibodies was evaluated by lethal challenge with the wild strain(WIV04)and multiple variants,including beta(B.1.351),delta(B.1.617.2),and omicron(B.1.1.529)at 200or 1000 TCID_(50),and the minimum antibody administration doses(5-1.25 mg/kg body weight)were also evaluated with delta and omicron challenge.Fully prophylactic protections were found in all challenged groups with both F61 and F61/H121 combination at the administration dose of 20 mg/kg body weight,and corresponding mice lung viral RNA showed negative,with almost all alveolar septa and cavities remaining normal.Furthermore,low-dose antibody treatment induced significant prophylactic protection against lethal challenge with delta and omicron variants,whereas the F61/H121 combination showed excellent results against omicron infection.Our findings indicated the potential use of broadly neutralizing monoclonal antibodies as prophylactic and therapeutic agent for protection of current emerged SARS-Co V-2 variants infection. | Jia Lu Qiangling Yin Rongjuan Pei Qiu Zhang Yuanyuan Qu Yongbing Pan Lina Sun Ding Gao Cuiqin Liang Jingwen Yang Wei Wu Jiandong Li Zongqiang Cui Zejun Wang Xinguo Li Dexin Li Shiwen Wang Kai Duan Wuxiang Guan Mifang Liang Xiaoming Yang | 2022 | Virologica Sinica2022，37，2： | 4 |

| 13 | Sirtl regulates testosterone biosynthesis in Leydig cells via modulating autophagy显示文摘Dear Editor,Steroid hormones are crucial signal molecules that regulate a large number of physiological and developmental pro-cesses.Testosterone is the key steroid hormone required for the development of male characteristics and also supports the physiology of the male reproductive system(Sinclair et al.,2015).Testosterone is primarily produced by the Leydig cells residing in the testicular interstitium.The cholesterol acts as a substrate for the biosynthesis of testosterone.Since steroidogenic cells are capable of stor-ing only very ltte hormone,rapid synthesis of hormone requires the mobilization of the precursor cholesterol,chiefly stored as intracellular lipid droplets(LDs)(Danielsen et al.,2016).Leydig cells are the major sites to produce testos-terone,there are extremely active autophagy in them,and a decline in steroidogenesis has also been associated with the decline of autophagic flow.Moreover,the disruption of autophagy leads to decreased intracellular LDs,and there-fore affects testosterone synthesis in the Leydig cells(Danielsen et al..2016;Gao et al,2018). | Muhammad Babar Khawar Chao Liu Fengyi Gao Hui Gao Wenwen Liu Tingting Han Lina Wang Guoping Li Hui Jiang Wei Li | 2021 | Protein & Cell2021，12，1： | 3 |
| 14 | Humic acid transport in saturated porous media:Influence of flow velocity and influent concentration显示文摘Understanding the transport of humic acids(HAs)in porous media can provide important and practical evidence needed for accurate prediction of organic/inorganic contaminant transport in different environmental media and interfaces.A series of column transport experiments was conducted to evaluate the transport of HA in different porous media at different flow velocities and influent HA concentrations.Low flow velocity and influent concentration were found to favor the adsorption and deposition of HA onto sand grains packed into columns and to give higher equilibrium distribution coefficients and deposition rate coefficients,which resulted in an increased fraction of HA being retained in columns.Consequently,retardation factors were increased and the transport of HA through the columns was delayed.These results suggest that the transport of HA in porous media is primarily controlled by the attachment of HA to the solid matrix.Accordingly,this attachment should be considered in studies of HA behavior in porous media. | Xiaorong Wei Mingan Shao Lina Du Robert Horton | 2014 | Journal of Environmental Sciences2014，26，12： | 3 |
| 15 | Distribution characteristics and indicator significance of Dechloranes in multi-matrices at Ny-lesund in the Arctic显示文摘In recent years, Dechloranes have been widely detected in the environment around the world.However, understanding and knowledge of Dechloranes in remote regions, such as the Arctic,remain lacking. Therefore, the concentrations of 5 Dechloranes in surface seawater, sediment,soil, moss, and dung collected from Ny-lesund in the Arctic were measured with the concentrations 93 pg/L, 342, 325, 1.4, and 258 pg/g, respectively, which were much lower than those in Asian and European regions. The mean ratios of anti-Dechlorane Plus(DP) to total DP(fanti) in seawater, sediment, soil, moss, dung, and atmospheric samples were 0.36, 0.21, 0.18,0.27, 0.66, and 0.43, respectively. Results suggested that the main source of DP in seawater,sediment, soil, and moss was long-range atmospheric transport. However, the ratio identified in dung was different, for which the migration behavior of the organism is probably the main source of DP. | Guangshui Na Wei Wei Shiyao Zhou Hui Gao Xindong Ma Lina Qiu Linke Ge Chenguang Bao Ziwei Yao | 2015 | Journal of Environmental Sciences2015，27，2： | 3 |
| 16 | Axial gradient excitation accelerates volumetric imaging of two-photon microscopy显示文摘Two-photon excitation fluorescence microscopy(TPM),owing to its capacity for subcellular resolution,intrinsic optical sectioning,and superior penetration depth in turbid samples,has revolutionized biomedical research.However,its layer-by-layer scanning to form a three-dimensional image inherently limits the volumetric imaging speed and increases phototoxicity significantly.In this study,we develop a gradient excitation technique to accelerate TPM volumetric imaging.The axial positions of the fluorophores can be decoded from the intensity ratio of the paired images obtained by sequentially exciting the specimen with two axially elongated two-photon beams of complementary gradient intensities.We achieved a 0.63μm axial localization precision and demonstrate the flexibility of the gradient TPM on various sparsely labeled samples,including bead phantoms,mouse brain tissues,and live macrophages.Compared with traditional TPM,our technique improves volumetric imaging speed(by at least sixfold),decreases photobleaching(i.e.,less than 2.07±2.89%in 25 min),and minimizes photodamages. | Yufeng Gao Xianyuan Xia Lina Liu Ting Wu Tingai Chen Jia Yu Zhili Xu Liang Wang Fei Yan Zhuo Du Jun Chu Yang Zhan Bo Peng Hui Li Wei Zheng | 2022 | Photonics Research2022，10，3： | 3 |
| 17 | Research of multi-path routing based on network coding in space information networks显示文摘A multi-path routing algorithm based on network coding is proposed for combating long propagation delay and high bit error rate of space information networks. On the basis of traditional multi-path routing, the algorithm uses a random linear network coding strategy to code data packets. Code number is determined by the next hop link status and the number of current received packets sent by the upstream node together. The algorithm improves retransmission and cache mechanisms through using redundancy caused by network coding. Meanwhile, the algorithm also adopts the flow distribution strategy based on time delay to balance network load. Simulation results show that the proposed routing algorithm can effectively improve packet delivery rate,reduce packet delay, and enhance network performance. | Yu Geng Zhong Congjiu Lan Xiaoyu Zhang Chi Wei Lina Liu Yansong | 2014 | Chinese Journal of Aeronautics2014，27，3： | 3 |
| 18 | Basic fibroblast growth factor protects against influenza A virus-induced acute lung injury by recruiting neutrophils显示文摘Influenza virus (IAV)infection is a major cause of severe respiratory illness that affects almost every country in the world.IAV infections result in respiratory illness and even acute lung injury and death,but the underlying mechanisms responsible for IAV pathogenesis have not yet been fully elucidated.In this study,the basic fibroblast growth factor 2 (FGF2)level was markedly increased in H1N1 virus-infected humans and mice.FGF2,which is predominately derived from epithelial cells,recruits and activates neutrophils via the FGFR2-PI3K-AKT-NFKB signaling pathway.FGF2 depletion or knockout exacerbated influenzaassociated disease by impairing neutrophil recruitment and activation.More importantly,administration of the recombinant FGF2 protein significantly aUeviated the severity of IAV-induced lung injury and promoted the survival of IAV-infected mice.Based on the results from experiments in which neutrophils were depleted and adoptively transferred,FGF2 protected mice against IAV , infection by recruiting neutrophils.Thus,FGF2 plays a critical role in preventing IAV-induced lung injury,and FGF2 is a promising potential therapeutic target during IAV infection. | Keyu Wang Chengcai Lai Tieling Li Cheng Wang Wei Wang Bing Ni Changqing Bai Shaogeng Zhang Lina Han Hongjing Gu Zhongpeng Zhao Yueqiang Duan Xiaolan Yang Li Xing Lingna Zhao Shanshan Zhou Min Xia Chengyu Jiang Xiliang Wang Penghui Yang | 2018 | Journal of Molecular Cell Biology2018，10，6： | 3 |

| 20 | Antibody Cocktail Exhibits Broad Neutralization Activity Against SARS-CoV-2 and SARS-CoV-2 Variants显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)has precipitated multiple variants resistant to therapeutic antibodies.In this study,12 high-affinity antibodies were generated from convalescent donors in early outbreaks using immune antibody phage display libraries.Of them,two RBD-binding antibodies(F61 and H121)showed high-affinity neutralization against SARS-Co V-2,whereas three S2-target antibodies failed to neutralize SARS-Co V-2.Following structure analysis,F61 identified a linear epitope located in residues G446–S494,which overlapped with angiotensinconverting enzyme 2(ACE2)binding sites,while H121 recognized a conformational epitope located on the side face of RBD,outside from ACE2 binding domain.Hence the cocktail of the two antibodies achieved better performance of neutralization to SARS-Co V-2.Importantly,these two antibodies also showed efficient neutralizing activities to the variants including B.1.1.7 and B.1.351,and reacted with mutations of N501 Y,E484 K,and L452 R,indicated that it may also neutralize the recent India endemic strain B.1.617.The unchanged binding activity of F61 and H121 to RBD with multiple mutations revealed a broad neutralizing activity against variants,which mitigated the risk of viral escape.Our findings revealed the therapeutic basis of cocktail antibodies against constantly emerging SARS-Co V-2 variants and provided promising candidate antibodies to clinical treatment of COVID-19 patients infected with broad SARS-Co V-2 variants. | Yuanyuan Qu Xueyan Zhang Meiyu Wang Lina Sun Yongzhong Jiang Cheng Li Wei Wu Zhen Chen Qiangling Yin Xiaolin Jiang Yang Liu Chuan Li Jiandong Li Tianlei Ying Dexin Li Faxian Zhan Youchun Wang Wuxiang Guan Shiwen Wang Mifang Liang | 2021 | Virologica Sinica2021，36，5： | 3 |
