目的探讨彩色多普勒超声(CDFI)在阴囊急症的诊断中其临床应用价值。方法采用ALOKA—SSD4000型彩色多普勒诊断仪,探头频率5—10MHz,对52例患者的患侧与健侧睾丸进行对照检测。结果急性睾丸炎和附睾炎占29例,睾丸扭转占14例,睾丸损伤占8例,腹股沟斜疝嵌顿占1例。表明CDFI可准确快速的区分睾丸扭转、炎症及睾丸损伤,其诊断敏感性及特异性均很高。结论CDFI可成为早期诊断阴囊急症的首选方法。  相似文献

应用放射免疫法,检测了不同年龄感染腮腺炎合并睾丸炎患者的生殖激素水平变化。结果表明,3组患者均存在不同程度的生殖激素紊乱,尤其以青春期发生感染的组Ⅱ有显著性改变。与对照组比较,组Ⅱ的睾酮(T)水平显著降低,促卵泡刺激素(FSH)和黄体生成素(LH)分别升高2.87和1.97倍,催乳素(PRL)和雌二醇(E2)分别增加1.81和1.98倍。提示感染腮腺炎性睾丸炎患者的生殖激素有明显改变,且与感染时患者的年龄密切相关,这类患者存在生育障碍。  相似文献

探讨睾丸、精液基因组DAZ基因缺失的检测方法在无、少精症患者病因诊断中的意义。选择35例特发性无、少精症患者作为研究对象,其中少精症18例、严重少精症12例、无精症5例;10例正常已生育健康男性作为正常对照。应用PCR技术,检测睾丸、精液基因组中的Y染色体上特异性序列标签位点(STS)的引物扩增了解基因缺失情况。35例患者中5例表现睾丸、精液基因组微缺失,其中少精症2例,严重少精症3例;其余30例患者和10例正常对照睾丸、精液基因组未见基因微缺失。精液和睾丸组织中基因组DAZ基因缺失的检测方法是诊断无、少精症病因的一种有效方法。  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

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-  相似文献

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-  相似文献

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  相似文献

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  相似文献
