World Journal of Gastroenterology 2008年第5期14卷 771-775页

AIM： To study the relationship between anti-β2- glycoprotein Ⅰ （aβ2GPⅠ） antibodies and platelet activation state in patients with ulcerative colitis （UC） and its significance. METHODS： Peripheral blood samples were collected from 56 UC patients （34 males and 22 females, aged 43.5 years, range 21-66 years）, including 36 at active stage and 20 at remission stage, and 25 sex-and age-matched controls. The level of aβ2GP Ⅰ was measured by ELISA. The platelet activation markers, platelet activation complex- Ⅰ （PAC- Ⅰ ） and P-selectin （CD62P） were detected by flow cytometry. RESULTS： The A value for IgG aβ2GP Ⅰ in the active UC group was 0.61 ± 0.13, significantly higher than that in the remittent UC and control groups （0.50 ± 0.13 and 0.22 ± 0.14, P 〈 0.01）. There was a significant difference between the two groups （P 〈 0.01）. The A value for IgM aβ2GP Ⅰ in the active and remittent UC groups was 0.43 ± 0.13 and 0.38 ± 0.12, significantly higher than that in the control group （0.20 ± 0.12, P 〈 0.01）. However, there was no significant difference between the two groups （P 〉 0.05）. The PAC- Ⅰ positive rate for the active and remittent UC groups was 30.6% ± 7.6% and 19.6% ± 7.8% respectively, significantly higher than that for the control group （6.3% ± 1.7%,P 〈 0.01）. There was a significant difference between the two groups （P 〈 0.01）. The CD62P positive rate for the active and remittent UC groups was 45.0% ± 8.8% and 31.9% ± 7.8% respectively, significantly higher than that for the control group （9.2% ± 2.7%, P 〈 0.01）. There was a significant difference between the two groups （P 〈 0.01）. In the active UC group, the more severe the state of illness was, the higher the A value for IgG aβ2GP Ⅰ was, and the positive rate for PAC-Ⅰ and CD62P was positively correlated with the state of illness （Faβ2GP Ⅰ = 3.679, P 〈 0.05; FPAC-Ⅰ （%） = 5.346, P 〈 0.01; and FCD62P （%） = 5. 418, P 〈 0.01）. Meanwhile, in the same state of illness, the A value for IgG aβ2GP Ⅰ was positively correl

针对视频描述中语义特征不能兼顾全局概括信息和局部细节信息,影响视频描述效果的问题,提出一种视频描述中全局-局部联合语义生成网络GLS-Net.首先利用全局与局部信息的互补性设计全局和局部语义提取单元,2个单元采用残差结构的多层感知机(residual multi-layer perceptron,r-MLP)来增强特征提取效果;然后联合概括性全局语义和细节性局部语义增强语义特征的表达能力;最后将该语义特征作为视频内容编码,提升视频描述模型性能.在MSR-VTT和MSVD数据集上,以语义辅助视频描述(semantics-assisted video captioning network,SAVC)网络为基础进行的实验的结果表明,GLS-Net优于现有同类算法,与SAVC网络相比,准确率平均提升6.2%.

从语言使用角度研究语法的思路在结构主义语言学和生成语法中一直受到忽视。20世纪80年代以后,自下而上、基于语言使用的语法研究模式逐渐占据主导地位。其中,认知语法更是明确提出基于用法的动态模式。按照这一模式,语言研究的重心从寻找概括力最强的规则转向描写处于不同概括层面的语法构式,真实语料的分析将取代纯粹的内省。语言研究将完整描写和解释语言结构,而不是将大部分语言现象排除在外。

The surface plasmonic resonance(SPR)effect of Bi can effectively improve the light absorption abilities and photogenerated charge carrier separation *** this study,a novel ternary heterojunction of g-C3N4/Bi2MoO6/Bi(CN/BMO/Bi)hollow microsphere was successfully fabricated through solvothermal and in situ reduction *** results revealed that the optimal ternary 0.4 CN/BMO/9 Bi photocatalyst exhibited the highest photocatalytic efficiency toward rhodamine B(RhB)degradation with nine times that of pure *** DRS and valence band of the X-ray photoelectron spectroscopy spectrum demonstrate that the band structure of 0.4 CN/BMO/9 Bi is a z-scheme *** experiments also provided solid evidence that the·O^2-(at-0.33 eV)is the main species during dye degradation,and the conduction band of g-C3N4 is only the reaction site,demonstrating that the transfer of photogenerated charge carriers of g-C3N4/Bi2 MoO 6/Bi is through an indirect z-scheme ***,the enhanced photocatalytic performance was mainly ascribed to the synergetic effect of heterojunction structures between g-C3N4 and Bi2MoO6 and the SPR effect of Bi doping,resulting in better optical absorption ability and a lower combination rate of photogenerated charge *** findings in this work provide insight into the synergism of heterostructures and the SPR absorption ability in wastewater treatment.
