肺部感染时的体液免疫变化及其中西医结合治疗的免疫学评价

本文报告了68个肺部感染病例体液免疫指标——血清IgG、IgM、IgA和C_3的变化并选取其中26例分成两组(每组13例),使用两种不同的治疗方法(一组用中西医结合方法,另一组用单纯西医方法),比较两组治疗前后上述每种指标的变化,对所获数据进行统计学处理。结果表明。与正常人血清IgM、IgG、IgA和C_3相比,患有肺部感染的病人治疗前血清IgG明显降低,IgA明显上升,而IgM和C_3则无明显的变化。在治疗后,用中西医结合方法治疗的病人血清IgM比使用西医治疗病人的血清IgM明显高,在治疗前与正常人相比有明显升高的两组病人的IgA没有明显变化,IgG仍然很低,C_3亦仍无明显变化。

矽肺病人的免疫状态

本文检查了矽肺病人的多种免疫状态,发现患者同围血中T细胞百分率平均值比对照组显著降低,而B细胞百分率呈有意义增高;血清蛋白、r、α_1、α_2球蛋白有随病程进展而增高趋势;血清免疫球蛋白IgG和IgA含量的增高亦与病程相一致,至Ⅱ期矽肺二者含量增高显著,但IgM含量未见明显变化,仅在矽肺合并结核组,IgG、IgA、和IgM含量呈明显增高;患者组类风湿因子(RF)和抗核抗体(ANA)合并阳性率(24.5％)比接尘组(13.3％)为高;血中循环免疫复合物(CIC)阳性检出率较高,但Ⅰ期矽肺组与对照组相比,未呈统计学差别;患者血中总补体(CH_(50))和C_8含量未见明显变化。根据患者的T细胞检出率降低,B细胞增高、体液免疫结果与细胞免疫相一致,均和病程进展而呈现规律性变化,以及自身抗体增高等免疫现象,似与自身免疲性疾病有类同之处。随着杂交瘤技术的广泛应用,联系近年国外关于石棉肺免疫学研究,对T细胞亚群变化进行了讨论,这方面的深入研究,对阐明矽肺发病机理是有意义的。对矽肺免疫的进一步研究,从实验设计上也提出了有益的建议。

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.     

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
