后牙两段式可摘局部义齿的设计与制作

目的:改进常规可摘局部义齿设计的不足,增进固位、稳定。方法:采用两段式义齿结构、两个就位方向和插销锁连接固定。结果:义齿的固位、稳定效果明显提高。结论:插销式分段义齿是对常规可摘局部义齿的一种补充,对主基牙过度倾斜、固位要求高的患者,能够明显改善修复效果。     

Measurement of alveolar derecruitment in patients with acute lung injury: computerized tomography versus pressure–volume curve

Introduction  

Positive end-expiratory pressure (PEEP)-induced lung derecruitment can be assessed by a pressure–volume (P–V) curve method or by lung computed tomography (CT). However, only the first method can be used at the bedside. The aim of the study was to compare both methods for assessing alveolar derecruitment after the removal of PEEP in patients with acute lung injury or acute respiratory distress syndrome.     

氩氦刀的原理与应用中的优势和不足

氩氯刀是目前肿瘤治疗的新方法，其原理是通过组织细胞急冻急升温的方法实现的，比手术、化疗、放疗治疗方法简单，副作用小，费用低。但也存在冷冻后的问题，其适应证也受到限制。     

Psychodramatische Supervision in der Sozialen Arbeit

Anliegen dieses Artikels ist, die besondere Qualit?t und Chance von Psychodramatischer Supervision zu beschreiben, und gleichzeitig die Kompatibilit?t und fruchtbare Erg?nzung des Moreno’schen Ansatzes innerhalb des Formats Supervision innerhalb der Sozialen Arbeit auf zuzeigen. Dies wird anhand von 2 ausgew?hlten Praxisbeispielen dargestellt. Die Handlungskompetenz von Supervisandinnen und Supervisanden kann durch einfache psychodramatische Interventionen erweitert werden. Handlungshemmung wird überwunden, Spontaneit?t und Kreativit?t kommen ins Laufen und er?ffnen Perspektiven.     

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.     

庆大霉素对豚鼠前庭上皮IGF-1及其受体表达的影响

目的：研究庆大霉素对豚鼠前庭上皮胰岛素样生长因子-1（insulin-like growth factor-1，IGF-1）及其受体（insulin-like growth factor-1 receptor，EGF-1R）表达的影响，并探讨其生物学特性。方法：采用免疫组织细胞化学方法，以抗IGF-1及IGF-1R抗体为标记物，检测庆大霉素损伤后豚鼠前庭上皮自发修复期IGF-1及IGF-1R的表达变化和分布特点；采用Brdu体内标记和抗Brdu抗体免疫组化染色，检测庆大霉素损伤后豚鼠前庭上皮增殖的变化。结果：IGF-1及IGF-1R在正常成年豚鼠前庭上皮细胞中有低水平表达，庆大霉素损伤后，其表达增多。在1d组IGF-1及IGF-1R表达最强，其后逐渐减少。在正常对照组中无Brdu阳性细胞。各实验组均观察到Brdu阳性细胞，7d组最多。结论：庆大霉素损伤后，豚鼠前庭上皮IGF-1及IGF-1R表达增强，其时程变化与细胞增殖活动密切相关。IGF-1在豚鼠前庭上皮损伤后的细胞增殖中可能起重要信号转导作用。     

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…     

β-胡萝卜素立体异构体对环磷酰胺处理小鼠免疫功能的比较研究

就β-胡萝卜素立体异构体对环磷酰胺处理小鼠的免疫功能影响进行了比较研究。结果显示β-胡萝卜素立体异构体对外磷酰胺造成的免疫功能低下具有不同程度的改善作用，提高胸腺和脾脏指数，增强脾脏细胞对刀豆素A（ConA）的反应性和NK活性，血清溶菌酶含量也有所增加。综合各项指标，9-顺式和全反式混合物的作用最明显，提示一定浓度的9-顺式对于提高β-胡萝卜素对机体的总体作用是有一定意义的。
