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.     

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…     

胸膜腔造影和注射粘连剂对难治性气胸的诊治

目的：为更清晰地显示顽固性气胸的漏气部位和性质，为不能耐受手术者摸索一种新的治疗手段。方法：选择１８例患者，先用７６％泛影葡胺行胸膜腔造影，而后在局部注入少量粘连剂。结果：造影后发现多发性肺大泡８例，单发性肺大泡６例，肺大泡伴粘连带４例。病变分别位于左上肺，右上肺，中下肺野及叶间裂。注射粘连剂后，１５例一次成功，３例第二次成功。随防６～１８个月，未见复发。结论：该方法易掌握，无明显副作用。病变显示明显，易被患者接受，具有明显的临床效果和推广价值     

人端粒酶RNA的cDNA探针制备及其对胃粘膜细胞端粒酶RNA表达的检测

目的 建立人端粒酶RNA表达的检测方法。方法 制备人端粒酶RNA，(human telomeraseRNA，hTR)的cDNA探针，分别应用RNA斑点杂交与端粒重复序列扩增法(TRAP)分析检测不同胃粘膜的端粒酶RNA的表达与端粒酶活性。结果 人端粒酶RNA的cDNA探针制备成功。18例活检胃癌组织及45例手术胃癌组织RNA斑点杂交检测的阳性率均为l00％，相应TRAP分析的阳性率分别为88．89％、86．67％，低于RNA斑点杂交(P＜0．05)。同时RNA斑点杂交结果提示在非癌胃组织中随着肠化程度增高人端粒酶RNA表达也增强。结论 RNA斑点杂交检测人端粒酶RNA，具有高度的敏感性和特异性，弥补了TRAP分析敏感性不足的缺点。     

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.     

非脱垂子宫经腹、阴式全切除术临床比较

目的 探讨非脱垂子宫经阴道与经腹全切术的临床比较。方法 2000年5月～2001年1月对阴式子宫全切术 (TVH)28例及腹式子宫全切术 (TAH)35例分为两组进行手术 ,对临床指标进行观察比较。结果 28例TVH手术均成功。平均重量255g(120～510g)。与TAH手术比较 ,其术后病率、肛门排气时间及术后住院天数有显著性差异 ( p<0.001及 p<0.05) ,但其手术时间及术中出血量无显著性差异 ( p>0.05)。结论 随着微创手术的开展 ,利用阴道天然孔道 ,经阴道切除较大的子宫是有效和安全的 ,手术的成功与术者经验、技术及子宫活动度有关 ,有合适器械也是手术成功的因素。
