The expression of emotion through nonverbal behavior in medical visits

Relationship-centered care reflects both knowing and feeling: the knowledge that physician and patient bring from their respective domains of expertise, and the physician’s and patient’s experience, expression, and perception of emotions during the medical encounter. These processes are conveyed and reciprocated in the care process through verbal and nonverbal communication. We suggest that the emotional context of care is especially related to nonverbal communication and that emotion-related communication skills, including sending and receiving nonverbal messages and emotional self-awareness, are critical elements of high-quality care. Although nonverbal behavior has received far less study than other care processes, the current review argues that it holds significance for the therapeutic relationship and influences important outcomes including satisfaction, adherence, and clinical outcomes of care.     

大鼠静脉窦高压致硬膜血管变化的研究

目的探讨大鼠静脉窦高压后硬膜血管变化及其静脉窦高压在硬脑膜动静脉瘘形成中的作用。方法体重200～250g的SD雄性大鼠110只,随机分为静脉窦高压组(85只)和假手术组(25只),将静脉窦高压组85只大鼠闭塞左侧横窦和上矢状窦前1／3,并吻合右侧颈总动脉和颈外静脉,制成静脉窦高压模型。假手术组大鼠单纯解剖相应的颈部血管和硬脑膜窦,但不行吻合或闭塞。术后90d,随机取7只静脉窦高压组大鼠和5只假手术组大鼠,行硬脑膜血管明胶墨汁灌注,观察硬膜血管的状况。结果术后90d静脉窦高压组和假手术组大鼠的硬膜血管数分别为(10.7±1.5)条／mm,(10.3±0.6)条／mm,差异无显著性。在静脉窦高压组中1只大鼠有硬脑膜动静脉瘘,其形态和结构与生理性动静脉短路类似。结论大鼠静脉窦高压一段时间后,颅内硬膜血管无明显增生。颅内硬脑膜动静脉瘘的形成很可能是由动静脉间的短路发展而来。     

儿科背式输液架的研制与应用

输液架是医院不可缺少的工具之一，国内医疗单位使用的输液架多种多样，但仅适用于病房使用，而适合儿科患儿移动的背式输液架甚少。针对以上缺陷，我们自行设计了一种可调式背式移动输液架，已应用于500例儿科患儿，效果较好。现介绍如下。     

Non-invasive Assessment of Coronary Flow Velocity Reserve: A New Method Using Transthoracic Doppler Echocardiography

Coronary flow reserve (CFR) has been used toassess coronary microcirculation and epicardial coro-nary stenoses[1— 3 ] . CFR is defined as the ratio ofcoronary flow under maximal coronary vasodilatationto coronary flow under resting conditions[4 ] .Whenthe cross- sectional area of epicardial coronary arteriesis constant,coronary flow velocity (CFV) ratios areequal to volume flow ratios.The most common method used clinically formeasuring CFVR is intracoronary Doppler flow(ICD) analysis re…

混合Poisson分布及其应用：疾病的统计分布（五）

本文讨论了混合Ｐｏｉｓｓｏｎ分布的性质、应用条件、参数的估计及混合Ｐｏｉｓｓｏｎ分布阶数的确定，指出混合Ｐｏｉｓｓｏｎ分布可用于混合样本的判别归类，并用Ｂａｙｅｓ的思想导出其判别归类方法。模拟试验结果表明：当混合Ｐｏｉｓｓｏｎ分布中各部分的比例相差不大，而各部分的均值相差较大时，抽样效果和拟合效果越好，所得到的估计值越接近理论值；反之效果越差。     

缺氧缺血性脑病新生鼠补钙前后脑细胞,红细胞内外钙的变化

为了观察一般剂量补钙对缺氧缺血性脑病（ＨＩＥ）脑细胞和红细胞内外钙变化的影响，以探讨ＨＩＥ时补钙是否增加脑细胞钙超载，用ＨＩＥ新生动物模型进行了实验研究，结果表明：（１）缺氧缺血时红细胞、脑细胞及脑组织出现钙积聚；（２）补钙后，血浆总钙浓度明显升高，而脑细胞、脑组织及红细胞钙积聚并未加重；（３）血浆总钙浓度与脑细胞或红细胞胞浆游离钙离子浓度无相关关系。提示：（１）ＨＩＥ时钙内流可能是全身性的；（２）对ＨＩＥ并低钙血症患儿吸氧后一般剂量补钙可能是安全的。     

DNA-Methylierung von monohalogenierten Methanen in F-344 Ratten

Monohalogenated methanes (methyl chloride, methyl bromide and methyl iodide) are mutagenic and carcinogenic. The possible mechanism of these effects, DNA methylation, was studied. DNA adducts from orgnas of F344 rats exposed to these chemicals were separated and identified with high performance liquid chromatography (HPLC) and gaschro-matography/massspectrometry (GC/ MS). DNA adducts, 7-methylguanine (7-MeG) and O⁶-Methylguanine(0⁸-MeG), incorporation of¹⁴C into de novo synthesis of nucleobases could be observed in enzymatic DNA hydrolysates by HPLC and determination of the radioactivity in the fractions. The formation of DNA add,ue,ts in the studied organs was only quantitatively different. The formation of O⁶-MeG was further pioved by analysing the acidic hydrolysates using HPLC with non-radioactive O⁶MeG as internal standard. 7-MeG and 3-MeA were identified with GC/MS analysis.
