AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma(sCC).METHODs: A systematic review was conducted according to the preferred reporting items for systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in ***: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal sCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal sCC's are in fact an extension of an anal sCC, and cytokeratin markers are a useful adjunct in this distinction. staging is most accurately reflected by the tumour-nodemetastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external siteof primary sCC with metastasis to the rectum. While the optimal treatm

本文探讨了创意产业项目融资的持续性问题。本研究的目的是探讨电影业是否可以有效地利用分层融资,将其推广至其他创意领域的项目。通过对德国和法国时装业的案例研究,我们检验了这一概念的可转移性。我们的研究结果表明,与电影行业相比,电影行业的分层不那么明显,因为行业特定的特点需要改变原有的方法。最后,我们提倡将分层融资原则应用于时尚产业,同时呼吁对这一课题展开更多的研究。

In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of science, the eXTP mission is expected to be launched in the mid 2020s.

高温条件下热液中的某些重要组分的水解作用

世界地质 1993年第1期 153-153页

作者： alexander Vakulenko Marinq Kazina 李晓华

在温度为673～923K压力为10～50MPa的范围内,研究了H2O-NaCl,H2O-KCl,H2-CaCl2系统的水解反应。实验之前,根据温度T在压力P=0.1MPa条件下计算了反应式MCl3+H2Ogas=MOHs,l+HClgas的差值△s,△G和平衡常数。随着温度从300K上升到1000K,所用盐类的水解反应的平衡常数增长20。在固相与气相平衡区内完成了一系列实验。并且将热力平衡常数和由实验数据计算所得的进行比较。多数实验是在液相与气相平衡区内在高压釜中进行的。平衡后,在淬火状态,测定了氢离子浓度,△pH=pH（1）-pH（g）的值随温度T的上升而增长。气相中富集了易挥发的HCl

当今俄罗斯的粮食安全:问题评估与前景保障

本文分析俄罗斯政界和学界对粮食安全问题的论述方式,重点关注相关纲领、规章、学术研究对"粮食安全"这一概念的矛盾界定。作者首先通过分析俄罗斯保障粮食安全的历史经验及现代策略,详述俄罗斯粮食政策的曲折发展历程,即从苏联的封闭自足模式到20世纪90年代的自由化、再到21世纪封闭自足的贸易保护主义模式。其次,在反思俄罗斯粮食安全指标的基础上,作者指出,不同类型粮食的产量增长不足以全面评估国家粮食安全,应将农业生产效率、优质粮食在所有社会阶层的可获得性及消费者监管粮食安全的能力纳入考察。最后,文章概述有关俄罗斯粮食安全的社会学研究,包括2015—2017年俄罗斯联邦总统国民经济与国家行政学院(RANEPA)农业研究中心的监测结果。分析发现,受访者的回答反映了内在矛盾的"二重封闭经济"模式,即俄罗斯民众一方面支持粮食保护主义和粮食民族主义的国家政策(国家自足政策);另一方面则通过家庭耕种争取粮食主权(家庭自足对策)。
