| 1 | The inhibitory effects of siRNA expression vector on CXCR4 expression in prostate carcinoma cell lines显示文摘Objective: To investigate the inhibitory effects of RNAi (RNA interference, RNAi) expression vector on CXCR4 expression in prostate carcinoma cell lines. Methods: Small interference RNA(siRNA) expression vectors for CXCR4 gene were constructed and transfected into prostate carcinoma cell lines(PC-3m and LNCaP)with liposomes. The expression of CXCR4 was detected by RT-PCR and western blot. Results: The expression of CXCR4 mRNA and protein in the PC-3m and LNCaP cells was reduced by RNAi expression vectors. The inhibitory rate of CXCR4 mRNA expression in the PC-3m cells was 87.81%±10.20%,56.10%±9.32% at the 24th hour and the 48th hour, compared with 56.93%±8.78%,49.24%±11.23% in LNCaP cells. The inhibitory rate of the expression of CXCR4 protein was 64.71%±6.68%,58.66%±11.56% respectively. Conclusion: The expression of CXCR4 gene can effectively be inhibited by RNAi expression vectors. | Yuefeng Du Yifei Xing Fuqing Zeng Peng Lu Xianyin Liu | 2006 | Journal of Nanjing Medical University2006，20，2： | 3 |
| 2 | Microstructural evolution of a Ni-Co based superalloy during hot compression atγ'sub-/super-solvus temperatures显示文摘The effects of strain rate on the microstructural evolution and deformation mechanism of a Ni-Co based superalloy were investigated by isothermal compression tests performed atγ'sub-solvus(1090℃)andγ'super-solvus temperatures(1150℃)with a wide strain rate range from 0.001 to 10 s^(-1)under a true strain of 0.693.Electron backscatter diffraction(EBSD),electron channeling contrast imaging(ECCI)and transmission electron microscope(TEM)techniques were used to characterize the microstructures.The results revealed that the dynamic recrystallization(DRX)volume fraction increased and stored energy of theγ'matrix grains decreased with increasing the strain rate duringγ'sub-solvus temperature deformation,while the opposite phenomena were observed duringγ'super-solvus temperature deformation.The comprehensive effect of initial grain size,primaryγ'phase,twins and adiabatic temperature rise led to these results.The primaryγ'particles undergone the deformation behavior within itself and obviously accelerated the DRX of the matrix.The microstructural evolution proved that discontinuous dynamic recrystallization(DDRX)was the dominant mechanism during the hot deformation carried out at bothγ'sub-solvus andγ'super-solvus temperatures.Primaryγ'particles obviously accelerated the nucleation step and retarded the growth step of DDRX duringγ'sub-solvus temperature deformation.Besides,the acceleration effect of primaryγ'particles on DDRX increased with the increase of strain rate.Continuous dynamic recrystallization(CDRX)was confirmed to be an assistant mechanism duringγ'super-solvus temperature deformation and was promoted with the increase of strain rate. | Peng Liu Rui Zhang Yong Yuan Chuanyong Cui Faguang Liang Xi Liu Yuefeng Gu Yizhou Zhou Xiaofeng Sun | 2021 | Journal of Materials Science & Technology2021，，18： | 2 |
| 3 | Charge density wave and weak Kondo effect in a Dirac semimetal CeSbTe显示文摘Using angle-resolved photoemission spectroscopy(ARPES) and low-energy electron diffraction(LEED), together with densityfunctional theory(DFT) calculation, we report the formation of charge density wave(CDW) and its interplay with the Kondo effect and topological states in CeSbTe. The observed Fermi surface(FS) exhibits parallel segments that can be well connected by the observed CDWordering vector, indicating that the CDWorder is driven by the electron-phonon coupling(EPC) as a result of the nested FS. The CDW gap is large(~0.3 eV) and momentum-dependent, which naturally explains the robust CDWorder up to high temperatures. The gap opening leads to a reduced density of states(DOS) near the Fermi level(EF), which correspondingly suppresses the many-body Kondo effect, leading to very localized 4 f electrons at 20 K and above. The topological Dirac cone at the X point is found to remain gapless inside the CDW phase. Our results provide evidence for the competition between CDWand the Kondo effect in a Kondo lattice system. The robust CDWorder in CeSbTe and related compounds provide an opportunity to search for the long-sought-after axionic insulator. | Peng Li BaiJiang Lv Yuan Fang Wei Guo ZhongZheng Wu Yi Wu DaWei Shen YueFeng Nie Luca Petaccia Chao Cao Zhu-An Xu Yang Liu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，3： | 1 |

| 11 | Adsorption experiment of water-soluble rare earth elements in atmospheric depositions and implications for source tracing in South China显示文摘The distribution patterns of rare earth elements(REEs)in fine-grained materials in various depositions were often found to be similar to those of the aeolian sediments deposited in the Loess Plateau in North China and the fine-grained materials were suggested to be derived from wind-blown dust.However,increasing evidence indicated that the REEs in the water-soluble portion of atmospheric depositions also displayed similar patterns to those of aeolian sediments.In this study,water-soluble REEs in three atmospheric depositions collected from different climatic zones in China were adsorbed with two adsorbents with distinct adsorption capacity,glass powder,and co-precipitated iron hydroxide.The results showed that the REEs adsorbed by the two adsorbents displayed patterns similar to those of the original atmospheric depositions.The typical characteristics of the REE patterns of atmospheric deposition can be well reproduced in the adsorbed REEs.The higher the REE concentrations in the atmospheric depositions,or the higher adsorption efficiency of the adsorbents,the better reproducibility of the REEs patterns.The results suggest that the REEs of the fine-grained materials in various sediments,which have a high adsorption capacity,especially those deposited in South China,may come from the water-soluble REEs in atmospheric deposition,and may not be appropriate tracers of wind-blown dust from North China. | Xiaojian Mi Yuan Li Yuefeng Liu Yu Xie Hanjie Li Xiaotao Peng Houyun Zhou | 2021 | Acta Geochimica2021，40，2： | 0 |
| 12 | Anomaly Detection with Artificial Immune Network显示文摘Inspired by the immune network theory,an adaptive anomaly detection paradigm based on artificial immune network,referred as APAI,is proposed. The implementation of the para-digm includes:initially,the first is to create the initial antibody network;then,through the learning of each training antigen,the antibody network is evolved and updated by the optimal antibod-ies. Finally,anomaly detection process is accomplished by major-ity vote of the k nearest neighbor antibodies in the network. The experiments used the famous Sonar Benchmark dataset in our study,which is taken from the UCI machine learning database. The obtained detection accuracy of APAI was 97.7%,which was very promising with regard to the other classification applications in the literature for this problem. In addition to its nonlinear classi-fication properties,APAI possesses biological immune network properties such as clonal selection,immune network,and immune memory,which can be applied to pattern recognition,classifica-tion,and etc. | PENG Lingxi LI Tao LIU Xiaojie CHEN Yuefeng LIU Caiming LIU Sunjun | 2007 | Wuhan University Journal of Natural Sciences2007，12，5： | 0 |

| 14 | Establishment of a Rat Model of Liver Venous Deprivation:Simultaneous Portal and Hepatic Vein Ligation显示文摘Background and Aims:The aim was to establish a liver venous deprivation(LVD)model in rats,compare hepatic hypertrophy between LVD and associated liver partition and portal vein ligation for staged hepatectomy(ALPPS),and explore the underlying mechanisms.Methods:The LVD or extended-LVD(e-LVD)group received portal vein ligation(PVL)combined with hepatic vein ligation(HVL).The ALPPS or eALPPS group received PVL plus parenchyma ligation.Liver regeneration was assessed by measuring the liver weight and performing pathological analysis.Liver functions and the sphingosine kinase 1(SPHK1)/sphingosine-1-phosphate(S1P)/sphingosine-1-phosphate receptor 1(S1PR1)pathway were also investigated.Results:All future liver remnants(FLRs)in the ALPPS,e-ALPPS,LVD,and e-LVD groups exhibited significant hypertrophy compared with the control group.The LVD and e-LVD procedures induced similar liver hypertrophy than that in the corresponding ALPPS groups.Furthermore,the LVD and e-LVD methods led to obvious cytolysis in the venous-deprived lobes as well as a noticeable increase in serum transaminase levels,while no necrosis was observed in the ALPPS and e-ALPPS groups.SPHK1/S1P/S1PR1 pathway were distinctly activated after operation,especially in congestive/ischemic livers.Conclusions:We describe the first rat model of LVD and e-LVD with simultaneously associated HVL and PVL.Compared with the ALPPS technique,the LVD or e-LVD procedure had a comparable overall effect on the hypertrophy response and a stronger effect on liver function.The SPHK1/S1P/S1PR1 pathway was involved in the LVD-or ALPPS-induced liver remodeling. | Yuefeng Zhang Xiaoqin He Peng Ma Liangkun Xiong Wenhui Bai Gaoshuo Zhang Yangtao Xu Wei Song Kaihuan Yu | 2023 | Journal of Clinical and Translational Hepatology2023，11，2： | 0 |

| 16 | Extraordinary toughening enhancement in nonstoichiometric vanadium carbide显示文摘1.Introduction Fracture toughness is the ability of materials against both the initiation and propagation of cracks[1],which is a crucial mechanical property for safety-critical applications of structural materials.Although the yield strength of ceramics is significantly higher than that of metallic materials,the fracture toughness is severely lower than that of metallic materials due to the strongly directional covalent bonding[1-3].For a long time,how to improve the fracture toughness of ceramics without the deterioration of strength(or hardness)has been one of the most challenging problems in materials science. | Chong Peng Hu Tang Changjian Geng Pengjie Liang Biao Wan Yujiao Ke Yuefeng Wang Peng Jia Wenfeng Peng Lina Qiao Kenan Li Xiaohong Yuan Yucheng Zhao Mingzhi Wang | 2022 | Journal of Materials Science & Technology2022，，2： | 0 |
| 17 | Structured Multi-Head Attention Stock Index Prediction Method Based Adaptive Public Opinion Sentiment Vector显示文摘The present study examines the impact of short-term public opinion sentiment on the secondary market,with a focus on the potential for such sentiment to cause dramatic stock price fluctuations and increase investment risk.The quantification of investment sentiment indicators and the persistent analysis of their impact has been a complex and significant area of research.In this paper,a structured multi-head attention stock index prediction method based adaptive public opinion sentiment vector is proposed.The proposedmethod utilizes an innovative approach to transform numerous investor comments on social platforms over time into public opinion sentiment vectors expressing complex sentiments.It then analyzes the continuous impact of these vectors on the market through the use of aggregating techniques and public opinion data via a structured multi-head attention mechanism.The experimental results demonstrate that the public opinion sentiment vector can provide more comprehensive feedback on market sentiment than traditional sentiment polarity analysis.Furthermore,the multi-head attention mechanism is shown to improve prediction accuracy through attention convergence on each type of input information separately.Themean absolute percentage error(MAPE)of the proposedmethod is 0.463%,a reduction of 0.294% compared to the benchmark attention algorithm.Additionally,the market backtesting results indicate that the return was 24.560%,an improvement of 8.202% compared to the benchmark algorithm.These results suggest that themarket trading strategy based on thismethod has the potential to improve trading profits. | Cheng Zhao Zhe Peng Xuefeng Lan Yuefeng Cen Zuxin Wang | 2024 | Computers, Materials & Continua2024，78，1： | 0 |
