| 1 | Plant Prime Editors Enable Precise Gene Editing in Rice Cells显示文摘Genome editing is revolutionizing plant research and crop breeding.Sequence-specific nucleases(SSNs)such as zinc finger nuclease(ZFN)and TAL effector nuclease(TALEN)have been used to create site-specific DNA double-strand breaks and to achieve precise DNA modifications by promoting homology-directed repair(HDR)(Steinert et al.,2016;Voytas,2013).Later,RNA-guided SSNs such as CRISPR-Cas9,Cas12a,Cas12b,and their variants were applied for genome editing in plants(Li et al.,2013;Nekrasov et alM 2013;Tang et al.,2017;Zhong et al.,2019;Ming et al.,2020;Tang et al.,2019).However,HDR relies on simultaneous delivery of SSNs and DNA donors,which has been challenging in plants(Steinert et al.,2016;Zhang et aL,2019).Another challenge for realizing efficient HDR in plants is that DNA repair favors nonhomologous end joining(NHEJ)pathways over HDR in most cell types(Puchta,2005;Qi et al.,2013). | Xu Tang Simon Sretenovic Qiurong Ren Xinyu Jia Mengke Li Tingting Fan Desuo Yin Shuyue Xiang Yachong Guo Li Liu Xuelian Zheng Yiping Qi Yong Zhang | 2020 | Molecular Plant2020，13，5： | 20 |
| 2 | Degradation potential of ofloxacin and its resulting transformation products during Fenton oxidation process显示文摘The degradation of ofloxacin(OFX)in the aqueous solution by Fenton oxidation process was investigated in the present study.The optimum operating conditions for the degradation of OFX in our system was determined.More importantly,the degradation pathways on a basis of the identification of transformation products during the degradation of OFX were proposed,which revealed that the initial degradation step could be associated with the decarboxylation at the quinolone moiety.Moreover,the detachment of the F element during the Fenton oxidation process has also been detected.Since the carboxylic group within OFX has been considered as an important bridge for binding quinolones with the DNA gyrase target,the decarboxylation process would offer insights into the reduction of antibacterial potentials. | Yunqing Pi Jinglan Feng Mengke Song Jianhui Sun | 2014 | Chinese Science Bulletin2014，59，21： | 10 |

| 4 | An improved ground motion intensity measure for super high-rise buildings显示文摘Ground motion intensity measure (IM) is an important part in performance-based seismic design. A reasonable and efficient IM can make the prediction of the structural seismic responses more accurate. Therefore, a more reasonable IM for super high-rise buildings is proposed in this paper. This IM takes into account the significant characteristic that higher-order vibration modes play important roles in the seismic response of super high-rise buildings, as well as the advantages of some existing IMs. The key parameter of the proposed IM is calibrated using a series of time-history analyses. The collapse simulations of two super high-rise buildings are used to discuss the suitability of the proposed IM and some other existing IMs. The results indicate that the proposed IM yields a smaller coefficient of variation for the critical collapse status than other existing IMs and performs well in reflecting the contribution of higher-order vibration modes to the structural response. Hence, the proposed IM is more applicable to seismic design for super high-rise buildings than other IMs. | LU Xiao YE LiePing LU XinZheng LI MengKe MA XiaoWei | 2013 | Science China(Technological Sciences)2013，56，6： | 9 |

| 7 | Activation of mitogen-activated protein kinases in satellite glial cells of the trigeminal ganglion contributes to substance P-mediated inflammatory pain显示文摘Inflammatory orofacial pain,in which substance P (SP) plays an important role,is closely related to the cross-talk between trigeminal ganglion (TG) neurons and satellite glial cells (SGCs).SGC activation is emerging as the key mechanism underlying inflammatory pain through different signalling mechanisms,including glial fibrillary acidic protein (GFAP) activation,phosphorylation of mitogen-activated protein kinase (MAPK) signalling pathways,and cytokine upregulation.However,in the TG,the mechanism underlying SP-mediated orofacial pain generated by SGCs is largely unknown.In this study,we investigated whether SP is involved in inflammatory orofacial pain by upregulating interleukin (IL)-1β and tumour necrosis factor (TNF)-α from SGCs,and we explored whether MAPK signalling pathways mediate the pain process.In the present study,complete Freund’s adjuvant (CFA) was injected into the whisker pad of rats to induce an inflammatory model in vivo.SP was administered to SGC cultures in vitro to confirm the effect of SP.Facial expression analysis showed that pre-injection of L703,606 (an NK-1 receptor antagonist),U0126 (an inhibitor of MAPK/extracellular signal-regulated kinase [ERK] kinase [MEK] 1/2),and SB203580 (an inhibitor of P38) into the TG to induce targeted prevention of the activation of the NK-1 receptor and the phosphorylation of MAPKs significantly suppressed CFA-induced inflammatory allodynia.In addition,SP promoted SGC activation,which was proven by increased GFAP,p-MAPKs,IL-1β and TNF-α in SGCs under inflammatory conditions.Moreover,the increase in IL-1β and TNF-α was suppressed by L703,606,U0126 and SB203580 in vivo and in vitro.These present findings suggested that SP,released from TG neurons,activated SGCs through the ERK1/2 and P38 pathways and promoted the production of IL-1β and TNF-α from SGCs,contributing to inflammatory orofacial pain associated with peripheral sensitization. | Yanyan Zhang Ning Song Fei Liu Jiu Lin Mengke Liu Chaolan Huang Daqing Liao Cheng Zhou Hang Wang Jiefei Shen | 2019 | International Journal of Oral Science2019，11，3： | 6 |
| 8 | Molecular crowding agents engineered to make bioinspired electrolytes for high-voltage aqueous supercapacitors显示文摘The development of low-cost and eco-friendly aqueous electrolytes with a wide voltage window is the key to achieving safe high energy density supercapacitors(SCs).In this work,a molecular crowding electrolyte is prepared by simulating the crowded environment in living cells.Ion transport in the molecular crowding electrolyte can be effectively improved via reducing the molecular weight of the crowding agent,polyethylene glycol(PEG).The results show that PEG with a molecular weight of 200(PEG200)can significantly improve ionic conductivity while maintaining a wide voltage window.These advantages enable commercial activated carbon-based SCs to work at 2.5 V with high energy density,outstanding rate performance and good stability for more than 10,000 cycles.On this basis,three series of molecular crowding electrolytes using sodium perchlorate,lithium perchlorate,and sodium trifluoromethanesulfonate as salts are developed,demonstrating the versatility of PEG200 for wide-voltage aqueous electrolytes. | Mengke Peng Li Wang Longbin Li Zhongyou Peng Xiannong Tang Ting Hu Kai Yuan Yiwang Chen | 2021 | eScience2021，1，1： | 5 |
| 9 | MATRIEX imaging:multiarea two-photon real-time in vivo explorer显示文摘Two-photon laser scanning microscopy has been extensively applied to study in vivo neuronal activity at cellular and subcellular resolutions in mammalian brains.However,the extent of such studies is typically confined to a single functional region of the brain.Here,we demonstrate a novel technique,termed the multiarea two-photon real-time in vivo explorer(MATRIEX),that allows the user to target multiple functional brain regions distributed within a zone of up to 12mm in diameter,each with a field of view(FOV)of ~200μm in diameter,thus performing two-photon Ca2+imaging with single-cell resolution in all of the regions simultaneously.For example,we demonstrate real-time functional imaging of single-neuron activities in the primary visual cortex,primary motor cortex and hippocampal CA1 region of mice in both anesthetized and awake states.A unique advantage of the MATRIEX technique is the configuration of multiple microscopic FOVs that are distributed in three-dimensional space over macroscopic distances(>1 mm)both laterally and axially but that are imaged by a single conventional laser scanning device.In particular,the MATRIEX technique can be effectively implemented as an add-on optical module for an existing conventional single-beam-scanning two-photon microscope without requiring any modification to the microscope itself.Thus,the MATRIEX technique can be readily applied to substantially facilitate the exploration of multiarea neuronal activity in vivo for studies of brain-wide neural circuit function with single-cell resolution. | Mengke Yang Zhenqiao Zhou Jianxiong Zhang Shanshan Jia Tong Li Jiangheng Guan Xiang Liao Bing Leng Jing Lyu Kuan Zhang Min Li Yan Gong Zhiming Zhu Junan Yan Yi Zhou Jian K Liu Zsuzsanna Varga Arthur Konnerth Yuguo Tang Jinsong Gao Xiaowei Chen Hongbo Jia | 2019 | Light(Science & Applications)2019，8，1： | 4 |
| 10 | Influence of soil——structure interaction on seismic collapse resistance of super-tall buildings显示文摘Numerous field tests indicate that the soilestructure interaction(SSI) has a significant impact on the dynamic characteristics of super-tall buildings,which may lead to unexpected structural seismic responses and/or failure.Taking the Shanghai Tower with a total height of 632 m as the research object,the substructure approach is used to simulate the SSI effect on the seismic responses of Shanghai Tower.The refined finite element(FE) model of the superstructure of Shanghai Tower and the simplified analytical model of the foundation and adjacent soil are established.Subsequently,the collapse process of Shanghai Tower taking into account the SSI is predicted,as well as its final collapse mechanism.The influences of the SSI on the collapse resistance capacity and failure sequences are discussed.The results indicate that,when considering the SSI,the fundamental period of Shanghai Tower has been extended significantly,and the collapse margin ratio has been improved,with a corresponding decrease of the seismic demand.In addition,the SSI has some impact on the failure sequences of Shanghai Tower subjected to extreme earthquakes,but a negligible impact on the final failure modes. | Mengke Li Xiao Lu Xinzheng Lu Lieping Ye | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014，6，5： | 4 |
| 11 | Tenofovir Alafenamide Fumarate,Tenofovir Disoproxil Fumarate and Entecavir:Which is the Most Effective Drug for Chronic Hepatitis B?A Systematic Review and Meta-analysis显示文摘Background and Aims:The therapeutic effect of tenofovir alafenamide fumarate(TAF),tenofovir disoproxil fumarate(TDF)and entecavir(ETV)on chronic hepatitis B(CHB)patients remains inconsistent.The aim of this study was to explore the differences in virological responses to TAF,TDF and ETV in patients with CHB.Methods:Literature searches were conducted of the PubMed,EMBASE,and the Cochrane Library databases to identify randomized controlled trials and observational studies published up to July 21,2020.Statistical comparisons of virological response between TDF,ETV,and TAF were carried out with pooled odds ratio(OR)values.Results:The virological response in TDF-treated CHB patients was notably superior to that of the ETV-treated CHB patients after 12-weeks[OR=1.12,95%confidence interval(CI):0.89–1.41],24-weeks(OR=1.33,95%CI:1.11–1.61),48-weeks(OR=1.62,95%CI:1.16–2.25),72-weeks(OR=1.43,95%CI:0.78–2.62),and 96-weeks(OR=1.56,95%CI:0.87–2.81)treatment.No significant difference was observed for the virological responses in CHB patients after 48-weeks treatment with TAF or TDF.The virological response in TDF+ETV-treated CHB patients was superior to that of TDF-treated CHB patients after 24-weeks,48-weeks(OR=1.54,95%CI:1.17–2.02),96-weeks,and 144-weeks.Conclusions:The virological response in TDF-treated CHB patients was superior to that in ETV-treated CHB patients,but there was no significant difference between TAF and TDF.In addition,the therapeutic effect of TDF+ETV was superior to TDF alone. | Xuefeng Ma Shousheng Liu Mengke Wang Yifen Wang Shuixian Du Yongning Xin Shiying Xuan | 2021 | Journal of Clinical and Translational Hepatology2021，9，3： | 3 |
| 12 | The hypoxia adaptation of small mammals to plateau and underground burrow conditions显示文摘Oxygen is one of the important substances for the survival of most life systems on the earth,and plateau and underground burrow systems are two typical hypoxic environments.Small mammals living in hypoxic environments have evolved different adaptation strategies,which include increased oxygen delivery,metabolic regulation of physiological responses and other physiological responses that change tissue oxygen utilization.Multiomics predictions have also shown that these animals have evolved different adaptations to extreme environments.In particular,vascular endothelial growth factor(VEGF)and erythropoietin(EPO),which have specific functions in the control of O_(2) delivery,have evolved adaptively in small mammals in hypoxic environments.Naked mole-rats and blind mole-rats are typical hypoxic model animals as they have some resistance to cancer.This review primarily summarizes the main living environment of hypoxia tolerant small mammals,as well as the changes of phenotype,physiochemical characteristics and gene expression mode of their long-term living in hypoxia environment. | Mengke Li Dan Pan Hong Sun Lei Zhang Han Cheng Tian Shao Zhenlong Wang | 2021 | Animal Models and Experimental Medicine2021，4，4： | 3 |
| 13 | Hydrothermal growth of hydroxyapatite and ZnO bilayered nanoarrays on magnesium alloy surface with antibacterial activities显示文摘Magnesium alloy(MgA)has been extensively used as orthopedic and cardiovascular scaffolds in virtue of its good biocompatibility,unique biodegradability and excellent mechanical properties.However,poor corrosion resistance and easy infection after implantation seriously limit the potential applications of MgA in the biomedical field.Herein,we fabricated bilayered nanoarrays of hydroxyapatite nanorods(HANRs)and ZnO nanorods(ZnONRs)onto the surface of MgA(MgA-MgO-HANRs-ZnONRs)via micro-arc oxidation(MAO)treatment,microwave-assisted hydrothermal and hydrothermal methods.The morphology and chemical composition of MgA-MgO-HANRs-ZnONRs was characterized by FE-SEM,XRD and EDS,indicating that HANRs-ZnONRs bilayered nanoarrays were fabricated on the surface of MgA-MgO.The surface of MgA-MgO-HANRs-ZnONRs exhibited excellent hydrophilicity as evidenced by the low water contact angle of 3°.Compared with the original MgA,the corrosion resistance of MgA-MgO-HANRs-ZnONRs was obviously improved with decreasing the corrosive current density(icorr)of 2 orders of magnitude.The MgA-MgO-HANRs-ZnONRs performed excellent antibacterial properties with the bactericidal rate of 96.5%against S.aureus and 94.3%against E.coli. | Mengke Peng Fenyan Hu Minting Du Bingjie Mai Shurong Zheng Peng Liu Changhao Wang Yashao Chen | 2020 | Frontiers of Materials Science2020，14，1： | 3 |
| 14 | Degradation of the antibiotic sulfamonomethoxine sodium in aqueous solution by photo-Fenton oxidation显示文摘In this study, photo-Fenton oxidation was applied to degradation of sulfamonomethoxine sodium (SMMS) in aqueous solution. The operation parameters of pH, temperature, and concentrations of H2O2, Fe2+ and SMMS were investigated. The optimum conditions for the photo-Fenton process were determined as follows: [SMMS]=4.53 mg/L, pH 4.0, [H2O2]=0.49 mmol/L, [Fe2+]= 19.51 μmol/L and T=25°C. Under these conditions 98.5% of the SMMS degraded. The kinetics were also studied, and degradation of SMMS by the photo-Fenton process could be described by first-order kinetics. The apparent activation energy was calculated as 23.95 kJ/mol. Mineralization of the process was investigated by measuring the chemical oxygen demand (COD), and the COD decreased by 99% after 120 min. This process could be used as a pretreatment method for wastewater containing sulfamonomethoxine sodium. | SUN JianHui FENG JingLan SHI ShaoHui PI YunQing SONG MengKe SHI Yan | 2012 | Chinese Science Bulletin2012，57，5： | 2 |
| 15 | Frictional stability of Longmaxi shale gouges and its implication for deep seismic potential in the southeastern Sichuan Basin显示文摘Microearthquakes accompanying shale gas recovery highlight the importance of exploring the frictional and stability properties of shale gouges.Aiming to reveal the influencing factors on fault stability,this paper explores the impact of mineral compositions,effective stress and temperature on the frictional stability of Longmaxi shale gouges in deep reservoirs located in the Luzhou area,southeastern Sichuan Basin.Eleven shear experiments were conducted to define the frictional strength and stability of five shale gouges.The specific experimental conditions were as follows:temperatures:90–270°C;a confining stress:95 MPa;and pore fluid pressures:25–55 MPa.The results show that all five shale gouges generally display high frictional strength with friction coefficients ranging from 0.60 to 0.70 at the aforementioned experiment condition of pressures,and temperatures.Frictional stability is significantly affected by temperature and mineral compositions,but is insensitive to variation in pore fluid pressures.Fault instability is enhanced at higher temperatures(especially at>200°C)and with higher tectosilicate/carbonate contents.The results demonstrate that the combined effect of mineral composition and temperature is particularly important for induced seismicity during hydraulic fracturing in deep shale reservoirs. | Fengshou Zhang Li Cui Mengke An Derek Elsworth Changrong He | 2022 | Deep Underground Science and Engineering2022，1，1： | 2 |
| 16 | Transcriptome and physiological analyses provide insights into the leaf epicuticular wax accumulation mechanism in yellowhorn显示文摘Plantations and production of yellowhorn,one of the most important woody oil and urban greening trees widely cultivated in northern China,have gradually become limited by drought stress.The epicuticular wax layer plays a key role in the protection of yellowhorn trees from drought and other stresses.However,there is no research on the mechanism of wax loading in yellowhorn trees.In this study,we investigated the anatomical and physiological characteristics of leaves from different germplasm resources and different parts of the same tree and compared their cuticle properties.In addition,the different expression patterns of genes involved in wax accumulation were analyzed,and a coexpression network was built based on transcriptome sequencing data.Morphological and physiological comparisons found that the sun leaves from the outer part of the crown had thicker epicuticular wax,which altered the permeability and improved the drought resistance of leaves,than did shade leaves.Based on transcriptome data,a total of 3008 and 1324 differentially expressed genes(DEGs)were identified between the sun leaves and shade leaves in glossy-and non-glossy-type germplasm resources,respectively.We identified 138 DEGs involved in wax biosynthesis and transport,including structural genes(such as LACS8,ECH1,and ns-LTP)and transcription factors(such as MYB,WRKY,and bHLH transcription factor family proteins).The coexpression network showed a strong correlation between these DEGs.The differences in gene expression patterns between G-and NG-type germplasm resources under different light conditions were very clear.These results not only provide a theoretical basis for screening and developing drought-resistant yellowhorn germplasm resources but also provide a data platform to reveal the wax accumulation process of yellowhorn leaves. | Yang Zhao Xiaojuan Liu Mengke Wang Quanxin Bi Yifan Cui Libing Wang | 2021 | Horticulture Research2021，8，1： | 2 |
| 17 | Synthesis of ordered Si nanowire arrays in porous anodic aluminum oxide templates显示文摘Highly ordered poly crystalline Si nanowire arrays were synthesized in porous anodic aluminum oxide (AAO) templates by the chemical vapor deposition (CVD) method. The morphological structure, the crystal character of Si nanowire arrays and the individual nanowire were analyzed by the transmission electron microscopy (TEM), scanning electron microscopy (SEM), atom force microscopy (AFM) and the X-ray diffraction spectrum (XRD), respectively. It is shown that most fabricated silicon nanowires (SiNWs) tend to be assembled parallelly in bundles and constructed with highly orientated arrays. This method provides a simple and low cost fabricating craftwork and the diameters and lengths of SiNWs can be controlled, the large area Si nanowire arrays can be achieved easily under such a way. The curling and twisting SiNWs are fewer than those by other synthesis methods. | Mengke Li Chengwei Wang Hulin Li | 2001 | Chinese Science Bulletin2001，46，21： | 2 |
| 18 | Chemical composition and glucose uptake effect on 3T3-L1 adipocytes of Ligustrum lucidum Ait. flowers显示文摘Ligustri lucidi Fructus is a traditional Chinese medicine and possesses various bioactivities,including hypoglycemic effect.Ligustrum lucidum Ait flowers are poorly investigated.Thus,we hypothesized that L.lucidum flowers also could have hypoglycemic effect.Chemical composition and glucose uptake effect of L.lucidum flowers on 3T3-L1 adipocytes were investigated.In this study,the components of L.lucidum flowers were investigated by various chromatographic and spectroscopic methods and the effects of L.lucidum flowers on the induction of glucose uptake were investigated by 3T3-L1 adipocytes.Seven compounds were isolated and identified from L.lucidum flowers,including ursolic acid(1),kaempferol-7-O-α-Lrhamnoside(2,KR),β-sitosterol(3),β-daucosterol(4),kaempferitrin(5,KF),10-hydroxy oleuropein(6,HO),and kaempferol-3-O-β-D-glucopyranoside-7-α-L-rhamnopyranoside(7,KGR).The results of glucose uptake showed that total extract(TE),KR,KF and HO from L.lucidum flowers significantly enhanced glucose uptake.This study demonstrated that compounds 2,5-7 were isolated for the first time from this plant and compounds 2 and 7 were isolated for the first time in genus Ligustrum,L.lucidum flowers,KR,KF and HO may possess potential hypoglycemic effect. | Lili Cui Jinmei Wang Mengke Wang Baoguang Wang Zhenhua Liu Jinfeng Wei Wenyi Kang | 2020 | Food Science and Human Wellness2020，9，2： | 2 |
