吃鱼的禁忌

因为鱼类食品中有嘌呤类物质,而痛风则是由于人体内的嘌呤代谢发生紊乱而引起的,主要表现为血液中尿酸含量过高,可使人的关节、结缔组织和肾脏等处发生一系列症状,痛风患者如果吃鱼会使病人症状加重。 肝硬化出血性疾病患者忌吃鱼 血小板减少、血友病、维生素K缺乏等出血性

原发性痛风34例误诊分析

原发性痛风（简称痛风）是由于嘌呤代谢紊乱所致的一组慢性疾病，其临床特点为高尿酸血症，及由此而引起的反复发作性痛风性急性关节炎、痛风石沉积、痛风石性慢性关节炎和关节畸形，常累及肾脏引起慢性间质性肾炎和尿酸肾结石形成。为进一步探讨本病的发病情况及临床特点，现将我院近几年来发现误诊的34例痛风患者的临床特点、误诊原因分析讨论如下。     

痛风36例控制不良原因分析及饮食指导

痛风是嘌呤代谢紊乱和(或)尿酸排泄减少所引起的一组疾病[1]。急性期主要临床表现为尿酸盐结晶沉积所致的特征性急性痛风性关节炎而致剧烈疼痛,关节红肿,痛风石形成;慢性期痛风石性关节炎,严重者甚至可致畸形或致残,且极易累及肾脏及心血管系统而引起一系列并发症,严重影响患者的身心     

长期"素食"可导致记忆力下降

随着“富贵病”的逐渐增多,人们对素食越来越感兴趣了。但是,最新研究表明。素食能养生,却不利于强身健体。植物性食品中含有丰富的维生素、无机盐和有机酸,而缺少造血的微量元素钴、锰、铁和铜等。此外,植物性食品除油料外,脂肪含量极少,但人的机体每昼夜至少需要60—70克脂肪,要想满足这种需要,就要吃5公斤的植物性食品。而且,植物蛋白永远代替不     

生活小常识二十一

1．豆腐含嘌呤较多，嘌呤代谢失常的痛风病人和血尿酸浓度增高的患者应慎食豆腐。 2．豆腐性偏寒，平素有胃寒者，如食用豆腐后有胸闷、反胃等现象，则不宜食用。     

痛风的中西医诊治进展

痛风是由于体内嘌呤代谢障碍、尿酸生成过多或／和尿酸排泄减少，致血中尿酸浓度增高所引起的一组异质性疾病。临床表现为高尿酸血症及尿酸盐结晶沉积所致特征性急性关节炎、痛风石、间质性肾炎，严重者呈关节畸形及功能障碍。痛风可分为原发性和继发性两大类，前者常与肥胖、糖脂代谢紊乱、高血压、动脉硬化和冠心病的聚集发生有关。     

天然多酚类成分缓解高尿酸血症及其机制研究进展

高尿酸血症(hyperuricemia, HUA)是一种机体中嘌呤类物质代谢紊乱导致血清中尿酸水平升高的一种代谢性疾病,严重者可导致痛风。HUA的发病机制主要包括酶活失调、尿酸转运体表达失衡、糖代谢及脂代谢紊乱、肠道稳态失衡等。许多研究报道了天然多酚对高尿酸血症和痛风具有良好的缓解作用。本文对HUA的发病机制和多酚类成分的降尿酸作用及其机制进行了总结与归纳,以期为降尿酸药物的研究与开发提供理论依据。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
