命名障碍中的词汇习得年龄效应

命名障碍即词回忆困难或找词困难,见于多种器质性脑病,是失语症中为常见的语言障碍.命名障碍机制的研究往往基于认知心理学的加工模式和神经解剖学,这些研究揭示了命名障碍中的词频、词汇习得年龄(words age of acquisition,AOA)等效应.AOA效应在国外是研究焦点,它的存在与否及机制的研究对命名障碍患者的病情评估和康复有很大帮助.为此,我们就命名障碍中AOA效应的新研究成果作一综述.

转化研究的多层次分析

While the pursuit of knowledge for its own sake is admirable, many medical researchers hope that their ideas, opinions, and research results will be used to improve health care in some capacity.The role of translational research is to construct the bridge between research and application.Translational research implies that the body of knowledge has matured to the point where successful application could result in a clinical, economic or procedural benefit to the health care system.This generally takes the form of the clinical introduction of innovative therapeutic agents, technologies, techniques and processes; in other words, the products of research.

精神医学中的生物统计学(7):治疗效应的异质性

In many clinical studies it is important to examine whether or not the effect of the treatment varies across patient subgroups[1].For example, does the effect of treatment for depression with a specific SSRI vary by gender? In other words, is there ‘heterogeneity of treatment effects' (HTE)? This information is important for clinical decision-making; clinicians can target a specific treatment to patients who are expected to benefit most from the treatment and seek alternative treatments for patients who are expected to benefit least from the treatment.

The effect of U50488, a selective k-opioid receptor agonist, on cardiac rhythm in the isolated perfused rat heart and intracellular calcium ([Ca2+] i) in the single ventricular myocyte were studied. The results showed that U50488 can induce arrhythmias dose-dependently in the isolated perfused rat heart and increase [Ca2+] i in the single ventricular myocyte. The effect of U50488 can be blocked by a selectivek-receptor antagonist, nor-binaltorphimine.The arrhythmogenic effects and the increase of [ Ca2 + ] i induced by U50488 were blocked by U73122, neomycin and streptomycin, which are selective phospolipase C inhibitors, but not by U73433, the inactive structural analog of U73122. These results demonstrated that the arrhythmogenic effect of cardiac k-receptor is due to activation of phosphoinositol/Ca2+ pathway.
