明代侯官人陈鸣鹤《东越文苑》首倡黄滔为“闽文章初祖”之说,经民国《福建通志》征引后,当代学人服膺此说者不胜枚举,几成不刊之论。经考证,《东越文苑》之前的现存文献皆载黄滔为“莆田文章初祖”,陈氏之说并无版本依据,从陈氏曾与黄滔同乡且具有相似的文学观念等迹象推测陈氏之说有刻意拔高之嫌。在唐五代闽地文学发展的历程中,中唐文人欧阳詹文学成就卓著,德行敦厚美善更有资格担任“闽中文章初祖”的称号,而唐末五代的黄滔则是莆田文学生发时期的集大成者,故“莆文章家以滔为初祖”的说法更有说服力。

近年来,电子竞技类型的比赛逐渐出现在大众的视野中,电竞比赛中对于各战队和选手战术和隐藏模式的分析是重要的一环。以往对于比赛的分析大多通过专家人工分析,存在主观因素强,难以分析战队和选手的隐藏模式等问题。本研究提出了一种时序感知的视图权重融合多视图聚类算法STVW-MVC,增加了视图重要性权重,改进了原算法中对于多视图信息一致性的处理,针对比赛中的各数据进行更准确的多视图聚类,以挖掘参赛选手或战队的战术和隐藏模式。相比原有的MVC-MAE算法,该算法更注重时序信息,使得时间序列靠后的信息会与时间序列靠前的信息产生信息一致性,而时间序列靠前的信息无法与其之后的信息产生一致性,能够更好地挖掘出潜在特征,从而进行更有效的聚类。除此以外,本研究还引入了视图重要性权重和视图相关性阈值,提高了聚类效果。实验表明,本研究算法的聚类结果更加紧凑合理,为电子竞技比赛数据的分析提供了一种更高效、更准确的方法。

目的探讨三七总皂苷(Panax notoginseng saponins,PNS)调控表皮生长因子受体(epidermal growth factor receptor,EGFR)/热休克蛋白27(heat shock protein 27,HSP27)轴对子宫内膜癌(endometrial cancer,EC)细胞和巨噬细胞交互作用的影响。方法将ishikawa细胞分为:Control组、DDP组、PNS给药组、M2-CM组、M2-CM+DDP组、M2-CM+PNS组、M2-CM+PNS+oe-NC组、M2-CM+PNS+oe-EGFR组、PNS(200 mg·L^(-1))+oe-NC、PNS(200 mg·L^(-1))+oe-EGFR、oe-NC组、oe-EGFR组、oe-EGFR+si-NC组和oe-EGFR+si-HSP27组。MTT检测细胞增殖,Transwell实验检测细胞侵袭,TUNEL检测细胞凋亡,qRT-PCR检测巨噬细胞极化标志物CD86、CD163的mRNA水平,ELISA检测iNOS、IL-12水平。Western-blot检测EGFR和HSP27蛋白表达。构建裸鼠移植瘤模型并用PNS治疗裸鼠,评估PNS在体内的作用。结果与Control组相比,PNS与DDP明显抑制ishikawa细胞增殖与侵袭,诱导其凋亡。M2-CM处理抑制M1型巨噬细胞标志物,促进M2型巨噬细胞标志物,诱导ishikawa细胞生长,但该作用被PNS处理逆转。EGFR被证实为PNS的靶点,且相对于M2-CM+PNS+oe-NC组,EGFR过表达促进M2型巨噬细胞标志物水平,诱导ishikawa细胞增殖与侵袭,并抑制细胞凋亡。敲减HSP27能够逆转EGFR过表达对ishikawa细胞生物学行为的影响。动物实验显示,PNS能够抑制肿瘤生长,减少肿瘤组织中CD163、EGFR和HSP27阳性表达。结论PNS通过调控EGFR/HSP27轴影响巨噬细胞和EC细胞互作用进而参与EC进展。

We study the ferrimagnetic properties of spin 1/2 and spin-1 systems by means of the effective field theory. The system is considered in the framework of bond dilution mixed Blume-Capel mode/ （BCM） with random single-ion anisotropy. The investigation of phase diagrams and magnetization curves indicates the existence of induced magnetic ordering and single or multi-compensation points. Special emphasis is placed on the influence of bond dilution and random single-ion anisotropy on normal or induced magnetic ordering states and single or multi-compensation points. Normal magnetic ordering states take on new phase diagrams with increasing randomness （bond and anisotropy）, while anisotropy induced magnetic ordering states are always occurrence no matter whether concentration of anisotropy is large or small. Existence and disappearance of compensation points rely strongly on bond dilution and random singleion anisotropy. Some results have not been revealed in previous papers and predicted by Néel theory of ferrimagnetism.

A method for in situ preparation of fluorescent gold nanoclusters(Au NCs) with bovine serum albumin/montmorillonite composite powder(Au NC-BSA/MMT) was developed, and the products were used to detect latent fingermarks. In this work, Au NCs were "grown" both inside and on the surface of BSA/MMT clay using one-step reduction of HAu Cl4 by BSA. The as-prepared Au NC-BSA/MMT nanocomposites emit intensive red fluorescence under the excitation of UV-visible light and show stable chemical features and low toxicity. The obtained fluorescent powders were characterized by UV-visible absorption spectroscopy,fluorescence spectroscopy, infrared spectroscopy, transmission electron microscopy/high-resolution transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy and X-ray diffraction to depict their sizes, structural information and optical features. Given their environmentally friendly preparation, simple operation, low cost, efficient UVvisible radiation-dependent photoluminescence and good affinity with finger residues, the in situ synthesized Au NC-BSA/MMT nanocomposite powders were used as an alternative fluorescent developing reagent for developing latent fingermarks deposited on various object surfaces(such as glass, aluminum foil, painted metal, plastic products and weighing papers) for individual identification. As results, the developed fingermarks with clear patterns and satisfactory level-2(minutiae points) and level-3(sweat pores) ridge details were obtained. Notably, treated prints could be excited by red light and emitted near infrared fluorescence, which was beneficial to avoid background interference and reduce the damage caused by UV light. With the advantages of the simple preparation process and good enhancement performance for latent fingermarks, the proposed method might be used in the preparation of various fluorescent probes for detecting trace evidence in forensic sciences.
