原发性肾上腺皮质癌的诊治分析

目的总结和提高原发性肾上腺皮质癌的诊治水平。方法回顾分析16例肾上腺皮质癌患者的临床资料。根据其临床症状、内分泌功能测定、影像学特点做出诊断，手术治疗并随访。结果16例患者中，内分泌功能紊乱者8例，以库欣征、性征异常、醛固酮增多症为主。超声、CT、MRI测定肿瘤直径为4．8～19．5cm，平均7．8cm。3例有远处转移。行根治性切除术13例，侵及同侧肾脏者做肾和肾上腙切除术2例，肾上腺肿瘤并腔静脉癌栓切除2例，腔静脉部分切除1例。病理结果：Ⅰ其耳2例，Ⅱ期8例，Ⅲ期3例，Ⅳ期3例。随访3-62个月，手术2年以上的11例患者中有6例仍存活，但1例肺转移，1例骨转移；死亡5例，平均存活26个月。结论肾上腺皮质癌患者预后差。影像学检查结合临床症状是早期诊断的关键，根治性手术是惟一有效的治疗方法。

前列腺癌的诊断和治疗进展前列腺癌的早期诊断

一、概况 在欧美国家,前列腺癌(Pca)是50岁以上男子最常见的恶性肿瘤,也是男性癌肿死亡的第二位原因(仅次于肺癌).因此,应重视Pca的筛查和早期诊断.尽管我国目前Pca发生率远低于欧美国家,但由于对本病的重视程度和防治力度不够,大多数患者出现症状而就诊时已为较晚期,失去了根治手术的机会,5年和10年生存率低,而医疗费用却上升较快.     

社区卫生服务:行走在点线面之间

2006开年,一个似曾相识的专有名词重返人们的视野——社区卫生服务,作为一种由政府强力推动的解困手法,被迅速纳入到有效缓解“看病难看病贵”的社会预期之中。由上而下的理论先导,只能经由行之有效的实践打磨才能得以还原。如果将整个社区卫生服务网络比作一个完整的神经系统,那么只有这个新     

大树倒了?

2004年8月26日,哈医大二院建院50周年庆典,位于哈市近郊的这所庞大的医院一扫往日的紧张忙碌,被欢快的乐、缤纷的鲜花、五色的气球和飞扬的条幅紧紧包裹。在庆典活动的中心——该院科技会馆,前去采访的本刊记者穿过络绎不绝的祝贺来宾和整齐划一的迎宾方阵,流连在会场外整齐摆放的各类奖杯、奖牌和科研成果宣传展板之间。这些被物化了的荣誉,几乎挤满了偌大的会堂一层走廊的每一寸角落,静静地宣示着这家医院半个世纪的所有自尊和自豪。在随后进行的庆祝仪式上,在医院各科室职工代表声情并茂的发言之后,哈医大二院院长张岂凡走上讲台。面对眼前如云的嘉宾和着装整齐统一的医护人员方阵,看得出这位著名的技术型院长难掩激情。他在题为“弘扬二院精神,再创世纪辉煌“的演讲词中这样形容：“50年的砥砺前行,50年的春华秋实,令天的哈医大二院已经成为我国医院之林中的一棵生机盎然的大树,根深叶茂,硕果累累。”命运总是在不动声色间逆转,谁能料到,一年后爆出的“天价医药费”事件,使曾经激情飞扬的哈医大二院再一次名动天下,所不同的是,再度亮相的哈医大二院,这一次坐在了被告席上。这棵生长了50年的医疗常青树,难道就此在瞬间轰然倒地?     

Analyzing and shaping human attentional networks.

In this paper we outline a conception of attentional networks arising from imaging studies as connections between activated brain areas carrying out localized mental operations. We consider both the areas of functional activation (nodes) and the structural (DTI) and functional connections (DCM) between them in real time (EEG, frequency analysis) as important tools in analyzing the network. The efficiency of network function involves the time course of activation of nodes and their connectivity to other areas of the network. We outline landmarks in the development of brain networks underlying executive attention from infancy and childhood. We use individual differences in network efficiency to examine genetic alleles that are related to performance. We consider how animal studies might be used to determine the genes that influence network development. Finally we indicate how training may aid in enhancing attentional networks. Our goal is to show the wide range of methods that can be used to suggest and analyze models of network function in the study of attention.     

镍铬合金烤瓷修复体394件中远期修复效果回顾性分析

IIEF-5与NEVA检测在阴茎勃起功能障碍诊断中的意义

目的探讨应用国际勃起功能评分5(IIEF-5)问卷表结合夜间阴茎勃起测定系统(NEVA)筛选勃起功能障碍(ED)的可行性及意义。方法148例门诊ED病人,应用IIEF-5问卷表评分,再通过NEVA测定仪监测夜间阴茎勃起情况,次日数据输入主机回放并分析。结果93例为心理性ED;在19~69岁的5个年龄组中,重度ED的比例由11.8%到55.0%,NEVA中度异常者IIEF积分(12.98±2.58)分,NEVA重度异常者IIEF积分(7.32±1.04)分。结论NEVA能有效地鉴别心理性与器质性ED,IIEF-5评分值与NEVA检测阴茎勃起时血容量变化值有相关性。IIEF-5与NEVA检测结合,能提高诊断和评估ED的可靠性。     

真空微波工艺条件对香脆鳙鱼片品质的影响

研究了预脱水鱼片含水量、微波功率、真空度对真空微波加工香脆鳙鱼片品质的影响,在此基础上,采用混合正交试验进一步优化了真空微波制备香脆鳙鱼片的工艺条件。研究结果表明,适宜的水分含量和微波功率可以提高鱼片的膨化率和脆度,改善鱼片的感官品质。高真空度可以改善鱼片的膨化作用和脆性,提高微波加热的效率,很大程度上避免了鱼片出现焦黑点。最佳的真空微波加热条件是预脱水鱼片水分质量分数控制在(15.3±1)%(50℃鼓风干燥3.5 h),微波功率设定为高火档(686±3.5)W,在真空度0.095 MPa下加热12 s后,间歇摇匀后再加热10 s。     

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.
