血浆血栓素B2和6-酮-前列腺素F1α水平与新生儿窒息关系

为观察不同程度窒息新生儿血浆血栓素B2(TXB2)和6-酮-前列腺素F1α(6-Keto-PGF1α)含量变化及其规律,选择对照组20例,轻度窒息组19例,重度窒息组21例,均在生后6 h内取股静脉血2 ml,进行放射免疫分析.结果TXB2及其与6-Keto-PGF1α比值在对照组分别为(202.42±53.91)pg/ml、1.81±0.61,轻度窒息组分别为(646.29±121.66)pg/ml、3.73±1.27,重度窒息组分别为(1443.27±254.61)pg/ml、6.83±2.39,三组方差分析,组间差异有显著性(F值分别为286.19,49.78,P＜0.001);6-Keto-PGF1α升高,三组分别为(117.22±33.14)Pg/ml、(184.73±52.65)pg/ml、(223.45±63.48)pg/ml(P＜0.05).提示窒息新生儿血浆TXB2和6-Keto-PGF1α含量及两者之比明显升高,重度窒息组比轻度窒息组升高明显;与对照组相比,其升高程度与窒息程度有关.     

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.     

重视老年胃癌患者的围手术期处理(附370例报告)

目的 总结老年胃癌的临床特点及围手术期处理经验。方法 回顾性分析我院1990年1月至2003年1月间共收治的370例老年胃癌患者的临床资料。结果 370例老年胃癌中290例（78．4％）伴有高血压、心脏病、糖尿病等老年常见病；术后发生并发症110例次，死亡16例；手术前有共存病者术后并发症的发生率（34．5％）明显高于无共存病者（12．5％），P〈0．01。结论 加强围手术期处理是降低老年胃癌患者并发症和死亡率的关键。     

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…
