人格特质、情绪状态对信息加工的影响
The Influence of Personality Traits and Mood State on Information Processing
 [PDF]


Advances in Social Sciences (ASS) , 2016, DOI: 10.12677/ASS.2016.51004
Abstract:
本研究的目的是探讨人格特质、情绪状态对信息选择性加工的影响,验证“特质一致性效应”和“心境一致性效应”。通过施测艾森克问卷从324名被试中筛选出典型内倾、外倾型各30名被试,根据人格特质和情绪状态各自两个水平将被试匹配成4组,进行词性辨别和自由回忆实验。结果表明:1) 特质一致性效应是存在的,被试在信息加工过程中偏爱加工与其人格类型一致的信息;2) 诱发的情绪状态类型对信息加工具有不同影响,即正性情绪对信息加工有积极影响,而负性情绪对信息加工则有消极影响;3) 词性辨别实验中,刺激词的类型在反应时、正确率和自由回忆成绩上均存在显著差异,词性和人格特质两因素在反应时和自由回忆成绩上存在交互作用。
This paper’s purpose is to explore the roles that personality traits and mood states play in the se-lective processing of information by adopting lexical identification task. In our investigation, we tested 324 college students by EPQ (Eysenck personality questionnaire) and chose 30 extroversion and 30 introversion participants. Then we divided the 60 participants into 4 groups with the lexical identification task. The results were as follows: 1) The “trait-congruent effects” existed in the experiment; participants preferred to process the information which is close to their personality types. 2) Type of artificial import mood state which consists of positive and negative emotions had different influences on the performances. Positive emotion could make the performances be better and the negative emotion could weaken them. 3) Type of words had significant differences on reaction time, accuracy and the free recall performance. Factors of personality traits and types of words had interaction on reaction time and the free recall performance.

 Prader-Willi syndrome (PWS) is a disorder caused by a deletion or disruption of genes in the proximal long arm of chromosome 15 or by maternal disomy in the proximal long arm of chromosome 15. Commonly associated characteristics of this disorder include diminished fetal activity, hypotonia, obesity, mental retardation, short stature, hypogonadism, and small hands and feet. We report a case of Prader-Willi syndrome with dilated cardiomyopathy, and review its Clinical manifestations, genetic characteristics and treatment method, then analysis the relation with the di- lated cardiomyopathy.

Abstract:
本文运用原位吸收光谱和荧光光谱技术研究了谷胱甘肽(GSH)包覆的ZnSe量子点在水相合成过程中光学性质的变化,结合X射线衍射(XRD)和原位X射线吸收精细结构谱(XAFS)的结果,探讨了该过程中量子点的结构演变。结果表明,ZnSe量子点的水相合成过程可分为三个阶段:快速生长→表面重构→晶格弛豫。最初的20分钟为快速生长期,ZnSe量子点的生长十分迅速,表面有很多缺陷;20至40分钟为表面重构期,ZnSe量子点的生长放缓,表面缺陷逐渐减少,荧光量子产率(PLQY)随之升高;40分钟后为晶格弛豫期,Se-Zn键的键长略有增加,ZnSe量子点的尺寸增加缓慢。
In situ absorption and PL spectroscopy were employed to investigate the luminescent properties of GSH capped ZnSe quantum dots (QD) obtained from aqueous synthesis. Combined with the re-sults of X-ray diffraction (XRD) and in situ X-ray absorption fine spectroscopy (XAFS), the struc-tural evolution of the QD during the growth process was probed. Detailed analysis reveals that, the growth stage of ZnSe QD could be divided into three stages: fast growth → surface reconstruction → lattice relaxation. In the initial 20 min, ZnSe QD grows quite fast with massive surface defects; during 20 - 40 min, the surface of ZnSe QD undergoes reconstruction, which means the growth rate slows down, and the surface defects reduce, accompanying with the increase of PL quantum yield. After 40 min, ZnSe QD goes through lattice relaxation, the bond length of Se-Zn slightly increases and the size of QD increases slowly.

Abstract:
视网膜静脉阻塞(retinal vein occlusion, RVO)是仅次于糖尿病性视网膜病变的常见视网膜血管疾病,是致盲的主要原因之一。黄斑水肿(macular edema)是RVO视力损害的最主要的原因。因此黄斑水肿的治疗是RVO治疗中最重要的内容,近年来抗VEGF药物的出现为黄斑水肿的治疗提供了一种新的治疗手段,目前大量研究证实无论是在消除或者减轻黄斑水肿方面,还是在提高视力方面,玻璃体腔内注射抗VEGF药物治疗RVO黄斑水肿都是有确切疗效的。本文就近年来有关RVO合并的黄斑水肿的抗VEGF治疗研究进展综述如下。
Retinal vein occlusion (RVO) is a common disease to cause blindness, which incidence is only next to diabetic retinopathy. The macular edema is the cause of vision loses. Therefore, the treatment of macular edema is one of the most important contents of RVO treatment. In recent years, the emergence of anti-VEGF drugs for the treatment of macular edema provides a new method. At present, a large of studies confirm whether in terms of eliminate or relieve the macular edema, or in terms of improving eyesight. Vitreous injection of anti-VEGF drug has exact curative effect. This paper reviews the recent advances in anti-VEGF treatment of macular edema secondary to retinal vein occlusion.
