3683例新生儿足跟采血的护理体会

新生儿疾病筛查是预防出生缺陷的主要措施,采集新生儿足跟血主要筛查先天性甲状腺功能减低症和苯丙酮尿症两疾病。新生儿足跟血的采集对采血时间、部位、方法及血片放置、送检等环节都有严格的要求,血片采集是否合格严重影响血筛的结果,对上述两种疾病的早期诊断和治疗具有非常重要的意义。     

新生儿血液中的多种氨基酸及尿液中的苯丙酮酸和对羟基苯乙酸的GC/MS分析

将新生儿血液中的氨基酸及尿液中的苯丙酮酸和对羟基苯乙酸采用不同的方法提取后，分别探讨两种衍生化技术在氨基酸代谢遗传算病筛查中的应用，即新生儿血样中的氨基酸经甲醇提取后用正丁醇和三氟乙酸酐和其衍生化，或者尿样加入乙腈心除蛋白后用乙酸乙酯提取，双（三甲基硅烷）乙酰硅烷化，衍生物用气相色谱－质谱了用仪选择离子模式检测，用外标同时定量分析血样中10种氨基酸的浓度，结果表明苯丙酮尿症患儿尿样中的苯丙酮酸和对羟基苯乙酸，以及血样中的苯丙氨酸的浓度明显高于正常新生儿，本方法可以推广至多种有机酸定量分析，以实现同步筛查多种氨基酸代谢缺陷症及其他遗传病。

调查蒙古斑在维吾尔族婴幼儿中的发生率及消退时间,完善该民族体质人类学资料,探索该民族人种构成特点及演化过程.肉眼观察新生儿身体各部皮肤,用半透明纸拓绘蒙古斑外形轮廓,以重量面积换算法确定蒙古斑的面积.结果表明新疆维吾尔自治区内,不同地区维吾尔族新生儿蒙古斑发生率不同,各地区之间差异显著,从东部到西部呈逐渐减少趋势,平均发生率为46.12%.从东部到西部,蒙古斑面积占体表面积比率逐渐减少,平均比率为0.69%.1岁内蒙古斑消退78.08%,5岁内消退98.71%,未发现蒙古斑对婴幼儿生理产生异常影响,消退后皮肤未出现异常.蒙古斑在新疆不同地区维吾尔族新生儿中的发生率及东西方向的梯度差异,体现了现代维吾尔族可能具有欧罗巴人种血源,欧罗巴人种血源对维吾尔族的掺入是由西部向东部逐渐深入的演化过程.     

浅谈苯丙酮尿症

苯丙酮尿症是由氨基酸代谢异常引起的一种常染色体隐性遗传性疾病,多见于小儿。临床上患儿异常情况在一岁左右最明显,以智能发育落后为主,行为异常、多动甚或有肌痉挛或癫痫小发作等神经系统严重损害症状;患儿的外貌在出生数月后因黑色素合成不足,皮肤白嫩、头发细黄、眼巩膜呈蓝色。其尿和汗液有鼠尿样恶臭。防治此病的关键是避免近亲结婚,早期诊断和早期治疗。

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
