Measurement of quality of life in bone marrow transplantation survivors

This study was designed to assess the reliability and validity of a Quality of Life (QOL) instrument on a sample of 179 allogeneic Bone Marrow Transplant (BMT) survivors. The QOL-BMT tool was developed specifically for this population and was based on the investigators' prior research and a conceptual model of Quality of Life. Patients who were at least 100 days post BMT completed the 30 item visual analogue questionnaire. The instrument measured physical symptoms (e.g., weight loss, frequent colds, skin changes, cataracts, sexual problems), psychological to illness, social concerns (e.g., relationship adjustment, return to work), and spiritual well-being (e.g., sense of control, future goals). Psychometric analysis of the instrument included measures of reliability and validity. The study findings demonstrate the unique aspects of QOL dimensions in BMT survivors and the value of QOL assessment in clinical practice and research.This study was supported by the City of Hope National Medical Center, NCI Cancer Center Core Grant, R30 CA 33572 and the City of Hope BRSG Grant Support.

目的 调查D4S1647、D6S2414基因座在中国汉族、蒙古族、藏族群体中的遗传分布规律。方法 采集308份血及唾液标本应用PCR技术，扩增产物用非变性聚丙酰胺凝胶电泳分离，银染显色分析。结果 两位点各群体基因型频率分布均符合Hardy-Weinberg平衡，每一位点等位基因频率分布在各群体间无显著差异；通过对10个汉族家系的遗传模式分析，证实了两位点等位基因传递遵循孟德尔遗传规律。结论 D4S1647、D6S2414基因座在中国汉族，蒙古族，藏族群体均具有高度遗传多态性。     

多巴胺受体的结构和功能

多巴胺是大脑中含量最丰富的儿茶酚胺类神经递质。多巴胺作为神经递质调控中枢神经系统的多种生理功能。多巴胺系统调节障碍涉及帕金森病，精神分裂症，Tourette综合征，注意力缺陷多动综合征和垂体肿瘤的发生等。本文综述了多巴胺受体的共同特征和各个受体的独特特征，以及它们在中枢神经系统的分布和功能，重点强调了多巴胺受体与学习记忆的关系。

女性伴侣在勃起功能障碍的诊治中的重要地位

女性伴侣在勃起功能障碍(erectile dysfunction,ED)中的地位日益受到重视。女性伴侣的性体验受到ED的严重不良影响,而她们对ED这个问题所采取的态度会直接影响男性患者寻求和坚持治疗的行为。因此在ED治疗的临床实践中,应同时考虑女性伴侣的作用。研究表明,伐地那非不仅可有效提高男性患者的勃起功能,还能显著改善女性伴侣的性生活质量,是ED伴侣双方的理想解决方案。     

血管内支架移植物治疗胸-腹主动脉瘤

目的　评价内支架移植物 (ESG)植入术治疗胸、腹主动脉瘤的有效性和安全性。方法　 2 8例胸、腹主动脉夹层动脉瘤 (AD或AAA) ,全麻下行血管内支架移植物治疗 ,其中 5例AD植入TALENT移植物 ,9例植入国产ESG ;7例AAA植入Zenith和TALENT分叉型ESG ,7例植入国产ESG。结果　 2 5例动脉假腔及动脉瘤得到有效隔绝。2例AD封堵失败 ;1例AAA移植物遮盖右肾动脉开口 ,术后肾体积缩小 ;1例AAA因多器官衰竭死亡。平均随访 18.5± 15 .1个月( 1～ 5 9个月 ) ,2 5例生活及工作情况良好。结论　ESG植入术可有效治疗StanfordB型AD和肾下AAA ;严格掌握适应证有助于减少并发症     

Effect of environment on extremely severe road traffic crashes：retrospective epidemic analysis during 2000-2001

Objective: To make an epidemiological analysis of the effect of environment on extremely severe road traffic crashes (RTCs). Methods: Epidemiologic data of extremely severe RTCs associated with environmental factors, including weather, topography, road conditions and other traffic conditions in Mainland China during 2000-2001, were collected and analyzed. Results: ( 1 ) During 2000-2001, there were 3 365 extremely severe RTCs with 13 666 deaths, 12 204 injuries and a direct economical loss of 136 million RMB. ( 2 ) Most extremely severe RTCs occurred in fine weather days and in the daytime. The high occurrence sites were plain areas, horizontal and straight roads, Grade B and C roads, ordinary road segment, and asphalt, smooth and mixed roads. (3) Compared with other RTCs, extremely severe RTCs were more likely to happen under following conditions: on cloudy, snowing, misty and blustering days; in hill and mountainous areas; on crooked and sloping roads; on freeway, Grade A, B, and C roads; mixed roads; ordinary, bridge, narrow and transitional roads; sand and dirt-roads; without traffic control measures; night without lighting. (4) Extremely severe RTCs of mountainous area or crooked and sloping roads were most severe in terms of deaths and injures per crash. Conclusions: Extremely severe RTCs are closely related with environmental factors. Rational road programming, enhancing road establishment and improving road conditions are probably effective measures to reduce the road traffic injuries.
