目的:探讨慢性心衰(CHF)患者血浆脑钠肽(BNP)检测的临床价值.方法:采用荧光免疫分析对101例CHF患者及45例健康对照者进行血浆BNP测定,同时以彩色多普勒超声心动仪测定CHF患者左心室舒张末期内径(LVEDD)、左心室射血分数(LVEF),并与血浆BNP水平作相关性分析,并对治疗心衰前后患者BNP水平作对比分析.结果:CHF组患者血浆BNP水平明显高于健康对照者(P＜0.01);不同心功能级别之间BNP值差异有统计学意义;心衰患者血浆BNP水平与NYHA、LVEDD、LVEF有明显相关性.结论:BNP是评价CHF患者心室功能的灵敏指标,BNP的检测在慢性心衰的诊断及治疗中具有较高的临床价值.     

血清Hcy水平与慢性肾脏病性心衰预后的分析

探究血清Hcy水平在评估慢性肾脏病性心衰患者预后的价值。收集2016年9月-2017年9月我院收治的60例慢性肾脏病性心衰患者作为观察对象,测定入院后血清Hcy水平,将Hcy值15μmol/L患者列入Hcy正常组(n=32),Hcy值≥15μmol/L患者列入高Hcy组(n=28)。比较两组治疗前后心功能分级;检测比较两组患者入院时及随访6个月后的血浆BNP、左室射血分数(LVEF)水平、再住院率及全因死亡率;并采用Logistic回归分析影响慢性肾脏病性心衰预后的相关因素。结果 6个月后,高Hcy组患者心功能NYHA分级差于治疗前及Hcy正常组(P0.05);高Hcy组患者的BNP水平高于Hcy正常组, LVEF水平低于对照组,差异具有统计学意义(P0.05);高Hcy组患者再入院率及全因死亡率均高于Hcy正常组(P0.05);血清Hcy、CysC水平为慢性肾脏病性心衰患者预后的重要影响因素(P0.05)。血清Hcy水平在慢性肾脏病性心衰患者的预后评估中具有一定的价值。     

脑钠肽与心力衰竭

脑钠肽(brain natriuretic peptide,BNP)主要储存于心室肌内,其分泌量随心室充盈压的高低变化,其生理作用为扩张血管,增加排钠,对抗肾上腺素-肾素-血管紧张素-醛固酮系统的水钠潴留效应,心力衰竭(Heart failure,HF)时,心室壁张力增加,心室内BNP分泌增加,使血浆中BNP水平升高,其值与心衰的严重程度呈正相关。为此,血浆BNP水平可作为评定心衰的进程和判断预后的指标。本文通过介绍BNP在国内外的研究进展,论述脑钠肽早期诊断心衰及对各期心衰者严重程度进行危险分层的价值。

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.     

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     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
