A systematic concept analysis of mental health promotion

This study explored and clarified the nature and characteristics of the concept of mental health promotion. The study also investigated how these characteristics appear in current policies and strategies. A total of 30 scientific articles and policy documents were identified and analysed using Rodgers’s systematic evolutionary concept analysis method. The analysis provided valuable information on the attributes, related concepts, antecedents, consequences and references of mental health promotion, indicating that the concept is a distinct concept comprising a unique set of attributes and characteristics. A concept mapping of mental health promotion was subsequently developed. The analysis and the concept mapping provide health professionals, policy-makers and researchers with a framework, upon which well-grounded mental health promotion practice and evaluation research can be based.     

定量磁化率图在脑微出血中的研究进展

脑微出血（CMB）常见于脑小血管病和神经退行性疾病。在病理上,CMB区域存在含铁血黄素沉积。定量磁化率图（QSM）可对这类超顺磁性物质精准定量,从而为CMB相关疾病的早期诊断提供有力工具,且在疾病严重程度分级和预后判断方面发挥重要作用。综述QSM用于诊断脑淀粉样血管病（CAA）、阿尔茨海默病（AD）、血管性痴呆（VaD）、多发性硬化（MS）、前哨性头痛（SH）、创伤性脑损伤（TBI）等中枢神经系统疾病CMB的研究现状及其进展。     

MRI thermometry: Fast mapping of RF‐induced heating along conductive wires

Conductive implants are in most cases a strict contraindication for MRI examinations, as RF pulses applied during the MRI measurement can lead to severe heating of the surrounding tissue. Understanding and mapping of these heating effects is therefore crucial for determining the circumstances under which patient examinations are safe. The use of fluoroptic probes is the standard procedure for monitoring these heating effects. However, the observed temperature increase is highly dependent on the positioning of such a probe, as it can only determine the temperature locally. Temperature mapping with MRI after RF heating can be used, but cooling effects during imaging lead to a significant underestimation of the heating effect. In this work, an MRI thermometry method was combined with an MRI heating sequence, allowing for temperature mapping during RF heating. This technique may provide new opportunities for implant safety investigations. Magn Reson Med, 2008. © 2008 Wiley‐Liss, Inc.     

胸部肿瘤科护理交接班思维导图的制作及应用

目的探讨思维导图在胸部肿瘤科护理交接班中的应用效果。方法将胸部肿瘤Ⅰ病区16名护士设为观察组,Ⅱ病区16名护士设为对照组。对照组采用传统的交接班方法,观察组在传统交接班方法的基础上制作护理交接班思维导图,应用其进行系统交班。结果观察组住院患者和接班护士对交接班的满意度显著高于对照组(均P0.01),观察组交班缺陷发生率显著低于对照组(P0.05,P0.01)。结论专科护理交接班思维导图的制作具有针对性,将其用于胸部肿瘤科交接班有利于提高住院患者和接班护士的满意度,提高交接班质量。     

多回波快速自旋回波T2 mapping定量技术评价心肌T2值的价值

 目的 探讨多回波快速自旋回波序列(MEFSE)的T₂ mapping定量技术评价左室心肌T₂值的价值。方法 30例健康志愿者,均行3.0T心脏磁共振(CMR)Cine电影、T₂WI序列、MEFSE T₂ mapping序列扫描,依据描述性研究方法,探索MEFSE T₂ mapping序列临床应用的可行性和可重复性,测定感兴趣区T₂值,应用方差分析方法统计分析心肌17节段和不同供血区下有无差异。应用Bland~Altman分析和Pearson相关分析方法研究此技术在不同观察者间的一致性。结果 健康志愿者17节段心肌T₂值不全相等(P＜0.01)。不同冠状动脉供血区T₂值无统计学差异(F=1.656,P=0.192)。左室心肌平均T₂值如下:基底部,(71.6±7.1)ms;中间部,(77.3±9.2) ms;心尖部,(83.0±8.5)ms,差异有统计学意义(F=14.245,P＜0.01)。根据Bland-Altman一致性分析和Pearson相关分析得到参数测量在观察者间具有良好的一致性,95%一致性界限(-6.1,24.8)ms,相关系数r=0.809。结论 CMR MEFSE T₂ mapping定量技术在心脏成像中具有较好的可行性和可重复性。中国健康志愿者中心肌T₂值存在节段性差异。     

MRI of the Hip for the evaluation of femoroacetabular impingement; past,present, and future

The concept of femoroacetabular impingement (FAI) has, in a relatively short time, come to the forefront of orthopedic imaging. In just a few short years MRI findings that were in the past ascribed to degenerative change, normal variation, or other pathologies must now be described and included in radiology reports, as they have been shown, or are suspected to be related to, FAI. Crucial questions have come up in this time, including: what is the relationship of bony morphology to subsequent cartilage and labral damage, and most importantly, how is this morphology related to the development of osteoarthritis? In this review, we attempt to place a historical perspective on the controversy, provide guidelines for interpretation of MRI examinations of patients with suspected FAI, and offer a glimpse into the future of MRI of this complex condition.
