自杀行为及其干预的研究进展

自杀已经成为一个世界范围内的重大公共卫生问题。中国的自杀特征具有独特性。自杀行为的发生往往是内在因素与外部因素相互作用的结果，它与社会学、心理学、伦理学、生物学、精神病学等各方面密切相关。自杀原因虽然错综复杂，但我们要提高意识，认识到自杀是一种可以预防的公共卫生问题。     

自律:在医患关系中的定位

医疗行为的特殊性，决定了医患双方在医学信息方面的不对称性和医者拥有一定的自由裁量权，因此，医者作为医疗服务的主体，如何增强自律意识，直接关系到诚信的树立及和谐的互动式医患关系的建立和发展。

Independent and court-ordered forensic neuropsychological examinations: Official statement of the National Academy of Neuropsychology

Independent forensic neuropsychological examinations are performed by neuropsychologists who are hired as independent contractors by third parties to make determinations regarding neuropsychological functioning. The responsibilities of neuropsychologists when performing independent or court-ordered forensic examinations differ from those of clinical examinations. Because neuropsychological training typically occurs in clinical contexts, the transition to forensic contexts may result in uncertainty about how to negotiate the unique responsibilities of the forensic examiner role. Neuropsychologists are responsible for maintaining the highest standards of professional practice when performing independent and court-ordered forensic examinations. To reach and maintain the highest standards of practice, neuropsychologists must understand the unique relationships with retaining parties and examinees and strive to maintain true independence and objectivity. Although a true neuropsychologist-patient relationship is not considered to exist within the context of a forensic neuropsychological evaluation, neuropsychologists have ethical responsibilities to both the retaining party and the examinee.     

聚环氧氯丙烷／液晶复合富氧膜的研究

研究了聚环氧氯丙烷(PECHCH)/N(4-乙氧基苄叉)4-丁基苯胺(EBBA)复合膜对氧气和氮气的透过性和选择性。用示差扫描量热计(DSC)、解偏振光强仪(DLI和偏光显微镜考察了复合膜的形态结构。结果表明,当PECH/EBBA复合膜处于液晶的向列相转变温度时,有较高的气体透过性和选择性。发现只有复合膜中EBBA含量在30wt％以上,PECH和EBBA呈非均相混合时,才有较明显的富氧效果。当EBBA含量达50wt%时,氧氮分离系数α=3.78。     

脑肿瘤意识障碍临床分析

本文观察502例脑肿瘤中,有47例出现意识障碍(9.4%)。其发生机制主要有:①脑疝形成;②普遍性颅内压增高引起脑缺氧;③肿瘤内出血;④肿瘤部位如额、颞叶、上脑干等的直接损害;⑤癫痫发作。脑疝形成是主要死亡原因。简要讨论了脑肿瘤意识障碍的临床特点、预后因素以及脑中心性疝的早期诊断。     

Long-term results of first-line sequential high-dose carboplatin, etoposide and ifosfamide chemotherapy with peripheral blood stem cell support for patients with advanced testicular germ cell tumor

OBJECTIVE: Standard chemotherapy shows relatively low long-term survival in patients with poor-risk testicular germ cell tumor (GCT). First-line high-dose chemotherapy (HD-CT) may improve the result. High-dose carboplatin, etoposide, ifosfamide chemotherapy followed by autologous peripheral blood stem cell transplantation (PBSCT) was investigated as first-line chemotherapy in patients with advanced testicular GCT. METHODS: Fifty-five previously untreated testicular GCT patients with Indiana 'advanced disease' criteria received three cycles of bleomycin, etoposide and cisplatin (BEP) followed by one cycle of HD-CT plus PBSCT, if elevated serum tumor markers were observed after three cycles of the BEP regimen. RESULTS: Thirty patients were treated with BEP alone, because the tumor marker(s) declined to normal range. Twenty-five patients received BEP and HD-CT. One patient died of rhabdomyolysis due to HD-CT. Three and six (13% and 25%) out of 24 patients treated with BEP and HD-CT achieved marker-negative and marker-positive partial responses, respectively. The other patients achieved no change. Fifteen (63%) are alive and 14 (58%) are free of disease at a median follow-up time of 54 months. Severe toxicity included treatment-related death (4%). CONCLUSIONS: HD-CT with peripheral stem cell support can be successfully applied in a multicenter setting. HD-CT demonstrated modest anticancer activity for Japanese patients with advanced testicular GCT and was well tolerated. This regimen might be examined for further investigation in randomized trials in first-line chemotherapy for patients with poor-risk testicular GCT.     

多济敷对面部磨削创面愈合的临床疗效观察

目的：本研究采用多济敷外用于面部皮损磨削术后创面,观察其对创面愈合时间、皮肤色素沉着等的变化。方法：采用区域神经阻滞或局部浸润麻醉,对不同类型的面部皮损34例进行皮肤磨削治疗,术后创面应用多济敷或凡士林纱布作为底层敷料包扎创面,术后换药一次,保留底层敷料。结果：2001年8月至2003年9月间,通过自身对照,34例面部磨削术后采用多济敷治疗组较凡士林纱布组创面愈合时间缩短(P＜0．05),经过6个月至2年的随访,皮肤色素沉着也有明显改善。结论：多济敷有利于缩短面部磨削术后创面愈合时间,改善面部色素沉着,外观满意。
