| 1 | Genome-wide CRISPR screen identifies synthetic lethality between DOCK1 inhibition and metformin in liver cancer显示文摘Metformin is currently a strong candidate anti-tumor agent in multiple cancers.However,its anti-tumor effectiveness varies among different cancers or sub-populations,potentially due to tumor heterogeneity.It thus remains unclear which hepatocellular carcinoma(HCC)patient subpopulation(s)can benefit from met-formin treatment.Here,through a genome-wide CRISPR-Cas9-based knockout screen,we find that DOCK1 levels determine the anti-tumor effects of met-formin and that DOCK1 is a synthetic lethal target of metformin in HCC.Mechanistically,metformin promotes DOCK1 phosphorylation,which activates RAC1 to facilitate cell survival,leading to metformin resistance.The DOCK1-selective inhibitor,TBOPP,potentiates anti-tumor activity by metformin in vitro in liver cancer cell lines and patient-derived HCC organoids,and in vivo in xenografted liver cancer cells and immunocompetent mouse liver cancer models.Notably,metformin improves overall survival of HCC patients with low DOCK1 levels but not among patients with high DOCK1 expression.This study shows that metformin effective-ness depends on DOCK1 levels and that combining metformin with DOCK1 inhibition may provide a promising personalized therapeutic strategy for met-formin-resistant HCC patients. | Junru Feng Hui Lu Wenhao Ma Wenjing Tian Zhuan Lu Hongying Yang Yongping Cai Pengfei Cai Yuchen Sun Zilong Zhou Jiaqian Feng Jiazhong Deng Ying Shu Kun Qu Weidong Jia Ping Gao Huafeng Zhang | 2022 | Protein & Cell2022，13，11： | 5 |
| 2 | Vertical structure and seasonal variation of tidal and residual currents in the northern Huanghai Sea显示文摘Analysis of tidal current and sea level has been made based on the observations from the summer of 2006 to the winter of 2007,respectively.The result indicates that a two-layer structure of residual current exists in summer,with its upper layer going northwestward and the lower layer southeastward.In addition,some strong residuals exist in the neighboring depth of the pycnocline during the current period of astronomical tide.In winter,except some individual layersthe residual currents mostly direct to the northwest,from which we can see the fluctuation of abnormal sea-level and the appearance of associated current because of the changes of the wind field.The analysis of tidal ellipse indicates that the direction of the maximum semidiurnal component is clockwise from summer to winter,with an angle of 16-18.Moreover,in summer the semidiurnal component rotates with depth clockwise while the diurnal component counterclockwise.However,the vertical structure is almost homogeneous in winter. | SONG Jun GUO Junru QIAO Lulu MU Lin YAO Zhigang LIU Yang LI Huan BAO Xianwen SUN Xiaoyan GAO Jia | 2011 | Acta Oceanologica Sinica2011，30，5： | 4 |
| 3 | Upregulation of GLT25D1 in Hepatic Stellate Cells Promotes Liver Fibrosis via the TGF-β1/SMAD3 Pathway In Vivo and In vitro显示文摘Background and Aims:Collagenβ(1-O)galactosyltransferase 25 domain 1(GLT25D1)is associated with collagen production and glycosylation,and its knockout in mice results in embryonic death.However,its role in liver fibrosis remains elusive,particularly in hepatic stellate cells(HSCs),the primary collagen-producing cells associated with liver fibrogenesis.Herein,we aimed to elucidate the role of GLT25D1 in HSCs.Methods:Bile duct ligation(BDL)-induced mouse liver fibrosis models,primary mouse HSCs(mHSCs),and transforming growth factor beta 1(TGF-β1)-stimulated LX-2 human hepatic stellate cells were used in in vivo and in vitro studies.Stable LX-2 cell lines with either GLT25D1 overexpression or knockdown were established using lentiviral transfection.RNA-seq was performed to investigate the genomic differences.HPLCMS/MS were used to identify glycosylation sites.Scanning electronic microscopy(SEM)and second-harmonic generation/two-photon excited fluorescence(SHG/TPEF)were used to image collagen fibril morphology.Results:GLT25D1 expression was upregulated in nonparenchymal cells in human cirrhotic liver tissues.Meanwhile,its knockdown attenuated collagen deposition in BDL-induced mouse liver fibrosis and inhibited mHSC activation.GLT25D1 was overexpressed in activated versus quiescence LX-2 cells and regulated in vitro LX-2 cell activation,including proliferation,contraction,and migration.GLT25D1 also significantly increased liver fibrogenic gene and protein expression.GLT25D1 upregulation promoted HSC activation and enhanced collagen expression through the TGF-β1/SMAD signaling pathway.Mass spectrometry showed that GLT25D1 regulated the glycosylation of collagen in HSCs,affecting the diameter of collagen fibers.Conclusions:Collectively,the upregulation of GLT25D1 in HSCs promoted the progression of liver fibrosis by affecting HSCs activation and collagen stability. | Shiwei Wang Lingling He Fan Xiao Meixin Gao Herui Wei Junru Yang Yang Shu Fuyang Zhang Xiaohui Ye Ping Li Xiaohua Hao Xingang Zhou Hongshan Wei | 2023 | Journal of Clinical and Translational Hepatology2023，11，1： | 1 |
| 4 | Electrostatic Interaction Tailored Anion-Rich Solvation Sheath Stabilizing High-Voltage Lithium Metal Batteries显示文摘Through tailoring interfacial chemistry,electrolyte engineering is a facile yet effective strategy for highperformance lithium(Li)metal batteries,where the solvation structure is critical for interfacial chemistry.Herein,the effect of electrostatic interaction on regulating an anion-rich solvation is firstly proposed.The moderate electrostatic interaction between anion and solvent promotes anion to enter the solvation sheath,inducing stable solid electrolyte interphase with fast Li+transport kinetics on the anode.This asdesigned electrolyte exhibits excellent compatibility with Li metal anode(a Li deposition/stripping Coulombic efficiency of 99.3%)and high-voltage LiCoO_(2) cathode.Consequently,the 50μm-thin Li||high-loading LiCoO_(2) cells achieve significantly improved cycling performance under stringent conditions of high voltage over 4.5 V,lean electrolyte,and wide temperature range(-20 to 60℃).This work inspires a groundbreaking strategy to manipulate the solvation structure through regulating the interactions of solvent and anion for highperformance Li metal batteries. | Junru Wu Ziyao Gao Yao Wang Xu Yang Qi Liu Dong Zhou Xianshu Wang Feiyu Kang Baohua Li | 2022 | Nano-Micro Letters2022，14，9： | 1 |
| 5 | 125I Radioactive Particles Drive Protective Autophagy in Hepatocellular Carcinoma by Upregulating ATG9B显示文摘Background and Aims:125I radioactive particles implantation have demonstrated efficacy in eradicating hepatocellular carcinoma(HCC).However,progressive resistance of HCC to 125I radioactive particles has limited its wide clinical application.Methods:We investigated the cellular responses to 125I radioactive particles treatment and autophagy-related 9B(ATG9B)silencing in HCC cell lines and Hep3B xenografted tumor model using Cell Counting Kit-8 reagent,western blotting,immunofluorescence,flow cytometry,transmission electron microscopy and immunohistochemistry.Results:In this study,we demonstrated that 125I radioactive particles induced cell apoptosis and protective autophagy of HCC in vitro and in vivo.Inhibition of autophagy enhanced the radiosensitivity of HCC to 125I radioactive particles.Moreover,125I radioactive particles induced autophagy by upregulating ATG9B,with increased expression level of LC3B and decreased expression level of p62.Furthermore,ATG9B silencing downregulated LC3B expression and upregulated p62 expression and enhanced radiosensitivity of HCC to 125I radioactive particles in vitro and in vivo.Conclusions:Inhibition of ATG9B enhanced the antitumor effects of 125I particle radiation against HCC in vitro and in vivo.Our findings suggest that 125I particle radiation plus chloroquine or/and the ATG9B inhibitor may be a novel therapeutic strategy for HCC. | Yunhua Xiao Jing Yuan Chongshuang Yang Junru Xiong Liangyu Deng Qinghua Liang Chuang He Liangshan Li Fengtian He Xuequan Huang | 2023 | Journal of Clinical and Translational Hepatology2023，11，2： | 1 |
| 6 | Achieving Ultra-Wideband and Elevated Temperature Electromagnetic Wave Absorption via Constructing Lightweight Porous Rigid Structure显示文摘Realizing ultra-wideband absorption,desirable attenuation capability at high temperature and mechanical requirements for real-life applications remains a great challenge for microwave absorbing materials.Herein,we have constructed a porous carbon fiber/polymethacrylimide(CP)structure for acquiring promising microwave absorption performance and withstanding both elevated temperature and high strength in a low density.Given the ability of porous structure to induce desirable impedance matching and multiple reflection,the absorption bandwidth of CP composite can reach ultra-wideband absorption of 14 GHz at room temperature and even cover the whole X-band at 473 K.Additionally,the presence of imide ring group in polymethacrylimide and hard bubble wall endows the composite with excellent heat and compressive behaviors.Besides,the lightweight of the CP composite with a density of only 110 mg cm^(−3) coupled with high compressive strength of 1.05 MPa even at 453 K also satisfies the requirements in engineering applica-tions.Compared with soft and compressible aerogel materials,we envision that the rigid porous foam absorbing material is particularly suitable for environmental extremes. | Zibao Jiao Wenjun Huyan Feng Yang Junru Yao Ruiyang Tan Ping Chen Xuewei Tao Zhengjun Yao Jintang Zhou Peijiang Liu | 2022 | Nano-Micro Letters2022，14，11： | 1 |

| 9 | The sensitivity of numerical simulation to vertical mixing parameterization schemes: a case study for the Yellow Sea Cold Water Mass显示文摘The vertical mixing parameterization scheme,by providing the eff ects of some explicitly missed physical processes and more importantly closing the energy budgets,is a critical model component and therefore imposes signifi cant impacts on model performance.The Yellow Sea Cold Water Mass(YSCWM),as the most striking and unique phenomenon in the Yellow Sea during summer,is dramatically aff ected by vertical mixing process during its each stage and therefore seriously sensitive to the proper choice of parameterization scheme.In this paper,a hindcast of YSCWM in winter of 2006 was implemented by using the Regional Ocean Modeling System(ROMS).Three popular parameterization schemes,including the level 2.5 Mellor-Yamada closure(M-Y 2.5),Generic Length Scale closure(GLS)and K-Profi le Parameterization(KPP),were tested and compared with each other by conducting a series of sensitivity model experiments.The infl uence of diff erent parameterization schemes on modeling the YSCWM was then carefully examined and assessed based on these model experiments.Although reasonable thermal structure and its seasonal variation were well reproduced by all schemes,considerable diff erences could still be found among all experiments.A warmer and spatially smaller simulation of YSCWM,with very strong thermocline,appeared in M-Y 2.5 experiment,while a spatially larger YSCWM with shallow mixed layer was found in GLS and KPP schemes.Among all the experiments,the discrepancy,indicated by core temperature,appeared since spring,and grew gradually by the end of November.Additional experiments also confi rmed that the increase of background diff usivity could eff ectively weaken the YSCWM,in either strength or coverage.Surface wave,another contributor in upper layer,was found responsible for the shrinkage of YSCWM coverage.The treatment of wave eff ect as an additional turbulence production term in prognostic equation was shown to be more superior to the strategy of directly increasing diff usivity for a coastal region. | Congcong BI Zhigang YAO Xianwen BAO Cong ZHANG Yang DING Xihui LIU Junru GUO | 2021 | Journal of Oceanology and Limnology2021，39，1： | 0 |
| 10 | The Change Features of the West Boundary Bifurcation Line of the North Equatorial Current in the Pacific显示文摘The equatorial Current in the North Pacific(NEC) is an upper layer westward ocean current, which flows to the west boundary of the ocean, east of the Philippines, and bifurcates into the northerly Kuroshio and the main body of the southerly Mindanao current. Thus, NEC is both the south branch of the Subtropical Circulation and the north branch of the Tropical Circulation. The junction of the two branches extends to the west boundary to connect the bifurcation points forming the bifurcation line. The position of the North Pacific Equatorial Current bifurcation line of the surface determines the exchange between and the distribution of subtropical and tropical circulations, thus affecting the local or global climate. A new identification method to track the line and the bifurcation channel was used in this study, focusing on the climatological characteristics of the western boundary of the North Equatorial Current bifurcation line. The long-term average NEC west boundary bifurcation line shifts northwards with depth. In terms of seasonal variation, the average position of the western boundary of the bifurcation line is southernmost in June and northernmost in December, while in terms of interannual variation, from spring to winter in the years when ENSO is developing, the position of the west boundary bifurcation line of NEC is relatively to the north(south) in EI Ni?o(La Ni?a) years as compared to normal years. | GUO Junru LIU Yulong SONG Jun BAO Xianwen LI Yan CHEN Shaoyang YANG Jinkun | 2015 | Journal of Ocean University of China2015，14，6： | 0 |
| 11 | Modeling and Simulation of Dynamic Unloading of Prestressed Rockmass显示文摘During the excavation of deep rock,a sudden change in boundary conditions will cause the in-situ stress on the excavation surface to release instantaneously.This disturbance propagates in the form of an unloading stress wave,which will enlarge the damage field of surrounding rock.In this paper,the dynamic unloading problem of the insitu stress in deep rock excavation is studied using theoretical,numerical,and experimental methods.First,the dynamic unloading process of rock is analyzed through adopting the wave equation,and the equivalent viscous damping coefficient of the material is taken into consideration.Calculations show that there is significant tensile strain in the rock bar when the strain rate is above 10^-1 s^-1.With an increase in the length or damping coefficient,the wave state will change from an underdamped to an overdamped state.Second,implicit and explicit solvers of the finite element method are employed to simulate rock unloading processes,which can be used to verify the theoretical results from one-dimensional to three-dimensional stress states.Finally,the dynamic unloading experiment of a onedimensional bar is used to further verify the validity and accuracy of the theoretical analysis. | Liang Wu Xiaorui Xiang Yang Chen Karrech Ali Junru Zhou Ming Chen | 2019 | Computer Modeling in Engineering & Sciences2019，，8： | 0 |
| 12 | Effects of Tai Chi on health outcomes in patients with type 2 diabetes mellitus: A systematic review and meta-analysis显示文摘Objective:To explore the effects and dose-response relationship of Tai Chi for type 2 diabetes mellitus(T2DM)and to evaluate the methodological quality of the included trials and evidence quality of the outcomes.Methods:Nine major English and Chinese databases were searched for randomized controlled trials of Tai Chi for T2DM from inception to December 2021.The effects and dose-response relationships were assessed with a meta-analysis and meta-regression using Stata.16.The methodological quality of the included studies was assessed using the risk of bias tool.The evidence quality of the outcomes was assessed using the GRADE tool.Results:A total of 24 studies with 1314 patients were included.Compared with the usual care,Tai Chi improved HbA1c(MD¼0.80%,95%CI[1.05,0.54],P<.001,I2¼18.29%,very low-quality evidence),FBG(SMD¼0.58,95%CI[0.86,0.31],P<.001,I2¼53.2%,low-quality evidence),fasting insulin(FIN),diastolic blood pressure,BMI,and the outcomes of quality of life(QoL)in patients with T2DM.However,when Tai Chi was compared with other exercise,there was no between-group difference in the HbA1c,FBG,TC,TG,HDL,LDL,BMI,and waist circumference(WC).Furthermore,the findings showed that an increase at every 18 weeks in length or an 823-h increase in the total time of Tai Chi intervention resulted in approximately a one unit reduction in the SMD of FBG.Conclusion:Compared with usual care,Tai Chi may improve HbA1c(with clinical significance),FBG,FIN,BMI,diastolic blood pressure,and outcomes of QoL in T2DM patients.The effects of Tai Chi were similar to those of other exercises on the HbA1c,FBG,TC,TG,HDL,LDL,BMI,and WC.Given the overall poor methodological quality and evidence quality,these findings should be treated cautiously. | Yiqing Cai Xin Liu Anni Zhao Junru Mao Xiangyu Guo Guangzong Li Jing Yang Yingqi Wu Yutong Fei | 2022 | Journal of Traditional Chinese Medical Sciences2022，9，2： | 0 |
| 13 | Recent Advances in Non-Precious Metal-Nitrogen-Carbon Single-Site Catalysts for CO_(2)Electroreduction Reaction to CO显示文摘The carbon dioxide electroreduction reaction(CO_(2)RR)to fuels and/or chemicals is an efficient prospective strategy to realize global carbon management using intermittent electric energy harvested from renewable sources.Highly efficient inexpensive electrocatalysts are required to achieve high energy and Faradaic efficiencies as well as fast conversion.Metal-nitrogen-carbon(M-N-C)single-site catalysts(SSCs)are highly competitive over precious metal catalysts in the CO_(2)RR to CO due to their high performance,easy regulation and low cost.In the past six years,intensive studies of M-N-C SSCs for CO_(2)RR to CO have been performed,and great progress has been achieved.This review focuses on the important topic of CO_(2)RR to CO with M-N-C SSCs.We first introduce the reaction mechanism of the CO_(2)RR to CO and the regulation of the electronic structure from a theoretical viewpoint.Then,the construction of M-N-C SSCs and the regulation of the electronic structure are demonstrated experimentally.The up-to-date electrocatalytic performance of M-N-C SSCs with different metal centers(Ni,Fe,Co and others)is summarized and compared systematically to highlight structure-performance correlations that were considered from both theoretical and experimental perspectives.Finally,the opportunities,challenges and future outlooks are summarized to deepen and widen research and applications in this promising field. | Yiqun Chen Junru Zhang Lijun Yang Xizhang Wang Qiang Wu Zheng Hu | 2022 | Electrochemical Energy Reviews2022，5，4： | 0 |
| 14 | Multi-functional and multi-scenario applications for MXene aerogels with synergistically enhanced asymmetric modules显示文摘The development of multifunctional materials and synergistic applications of various functions are important conditions for integrated and miniaturized equipment.Here,we developed asymmetric MXene/aramid nanofibers/polyimides(AMAP)aerogels with different modules using an integrated molding process.Cleverly asymmetric modules(layered MXene/aramid nanofibers section and porous MXene/aramid nanofibers/polyimides section)interactions are beneficial for enhanced performances,resulting in low reflection electromagnetic interference(EMI)shielding(specific shielding effectiveness of 2483(dB·cm^(3))/g and a low R-value of 0.0138),high-efficiency infrared radiation(IR)stealth(ultra-low thermal conductivity of 0.045 W/(m·K)and IR emissivity of 0.32 at 3–5μm and 0.28 at 8–14μm),and excellent thermal management performances of insulated Joule heating.Furthermore,these multifunctional AMAP aerogels are suitable for various application scenarios such as personal and building protection against electromagnetic pollution and cold,as well as military equipment protection against infrared detection and EMI. | Junru Yao Jintang Zhou Feng Yang Guiyu Peng Yijie Liu Zhengjun Yao Fan Wu Haibo Zeng | 2024 | Nano Research2024，17，4： | 0 |
| 15 | An Analysis of the Static and Dynamic Behavior of the Hydraulic Compensation System of a Multichannel Valve显示文摘Electro-hydraulic proportional valve is the core control valve in many hydraulic systems used in agricultural and engineering machinery.To address the problem related to the large throttling losses and poor stability typically associated with these valves,here,the beneficial effects of a triangular groove structure on the related hydraulic response are studied.A mathematical model of the pressure compensation system based on the power-bond graph method is introduced,and the AMESim software is used to simulate its response.The results show that the triangular groove structure increases the jet angle and effectively compensates for the hydrodynamic force.The steady-state differential pressure at the valve port of the new pressure compensation structure was 0.65 MPa.Furthermore,experimental results show that the pressure difference at the main valve port is 0.73 MPa,and that the response time is less than 0.2 s.It is concluded that the new compensation structure has good pressure compensation response characteristics. | Jikang Xu Ruichuan Li Yi Cheng Yanchao Li Junru Yang Chenyu Feng Xinkai Ding Huazhong Zhang | 2023 | Fluid Dynamics & Materials Processing2023，19，7： | 0 |
