多站点综合性毕业考试的改革与实践

我校改革临床医学专业毕业考试模式与方法，在临床实习过程中组织多站点综合性考试，采用闭卷笔试方法考核临床理论知识，占70％；采用实践操作与现场口试方法考核临床技能及相关知识，占20％；采用开卷笔试方法考核医疗文书书写，占10％。实践证明，此项改革能促进医学生端正实习态度，调动实习的积极性与主动性，引导医学生在实习中重视理论学习与临床实践的密切结合，促进临床教学质量的提高。     

胸腰段椎间盘突出症诊断的临床研究

目的探讨胸腰段椎间盘突出症临床表现的特点与规律，提高胸腰段椎间盘突出症的诊断水平。方法回顾性分析1995年9月～2004年1月我院经X线、CT、MRI及手术证实的胸腰段椎间盘突出症65例的临床资料，并将其分为低位胸椎组（T10-T12L1）43例，高位腰椎组（L1-2-L2-3）16例，多节段突出组6例。结果躯体感觉障碍89．2％（58／65）和下肢无力83．1％（54／65）是最多见的症状。9．2％（6／65）表现为上运动神经元损害，47．7％（31／65）表现为下运动神经元损害，43．1％（28／65）表现为上、下运动神经元混合性损害。仅3例为单根神经根损害，其余表现为多根神经或马尾神经的损害。腰背痛44．6％（29／65）和下肢无力40．0％（26／65）是最常见的首发症状。低位胸椎间盘突出以混合性运动神经元损害为主，占58．1％（25／43），易导致行走障碍、足下垂、下肢肌张力升高和病理征阳性；而高位腰椎间盘突出则以下运动神经元损害为主，占93．8％（15／16），易造成腰背、下肢疼痛及马尾神经损害。结论胸腰段椎间盘突出症的症状广泛、体征多样，当临床上存在以下情况时应高度怀疑胸腰段椎间盘突出症：①大腿前方、外侧或腹股沟部位出现感觉障碍者；②下肢无力，股四头肌，胫前肌肌力减退者（如足下垂）；③下肢运动或感觉障碍范围广泛、不规则，缺乏根性分布特征者；④上、下运动神经元损害同时存在，或虽表现为下运动神经元损害，但难以用低位腰椎间盘突出症解释者。     

Significance of Anticardiolipin Antibodies on Short and Long Term Allograft Survival and Function following Kidney Transplantation

The significance of anticardiolipin antibodies (ACAs) prior to renal transplantation is unclear. We studied a cohort of 337 patients who underwent renal transplantation from 1996 to 2001. Follow-up continued until allograft loss, patient death or 31 December 2002. The primary outcome was a composite endpoint of death-censored allograft loss or a 25% reduction in estimated glomerular filtration rate (GFR) from 1-month post-transplant. Secondary outcomes were allograft loss, a 25% reduction in GFR, acute rejection and creatinine at 1 year. IgG and IgM ACA titers were positive (> or =15) in 18.1% of recipients. There were no significant differences at baseline between recipients, except coumadin therapy in those with positive ACA titers (20% vs. 7.4%). Post-transplant, there was no increase in the primary outcome in ACA-positive patients, even after adjustment for anticoagulation with coumadin (HR = 1.42 [0.68, 2.96]). There was no difference in secondary outcomes between those with or without positive titers. Two of five patients with very high titers (>50) who were not anticoagulated had early graft loss. A positive ACA titer prior to kidney transplantation was not associated with inferior renal outcomes after transplantation, although more research is required to address the prognostic significance of very high ACA titers.     

Scientific quality of clinical research an analysis of 40 research projects in pharmacology/pharmacotherapy

Objective: The scientific quality of research is an important ethical issue. To clarify the quality of research projects in pharmacotherapy/pharmacology, 40 randomly selected research projects in pharmacotherapy/pharmacology submitted to a research ethics committee were reviewed. Results: Eight of the projects would not have contributed new knowledge nor were they necessary as controls for the results of previous research. Fifteen of the research protocols were of good quality, 15 could be used after revisions, and 10 were unfit for use. Eleven of the research projects were not finished 5 years after they were started. A written report was produced from 26 of the projects. Nine were of good quality and could be accepted for publication in a medical journal, 10 of the reports were in need of revision before publication, and 7 should not be accepted for publication. Conclusion: Research in this field ought to be improved, and ways to improve the standard of clinical trials in pharmacotherapy are dicussed.

32例青年食管癌临床病理分析

目的：探讨青年食管癌患者的临床病理特点。方法：以病例对照方式对32例青年食管癌临床病理特点进行分析，选用同期50岁以上食管癌病例40例为对照组。结果：青年食管癌患者与老年者相比，病理分化程度低，恶性度高，早期诊断率低，生存期短。结论：青年食管癌症状隐匿，诊断率低，预后差。     

因症就诊检出早期大肠癌的临床及病理学特征

目的探讨在就诊的肛肠病人中如何提高早期大肠癌的检出率。方法在１１家医院推广对肛肠病人的四项检查程序——直肠指检，乙结镜检查，大便隐血试验，和Ｘ线气钡灌肠造影。结果在４８２１例有肛肠症状的病人中，检出大肠癌１８８例，检出率为３．９％，其中１８０例有术后病理诊断。４７／１８０例（２６．１％）属早期癌（ＤｕｋｅｓｓｔａｇｅＡ）。４１／４７例由上述四项检查作出初步诊断。初发症状为：（１）便血（２６例，持续１５．２±９．４周后就诊，肿瘤平均直径２．５８ｃｍ）；（２）大便习惯改变（９例，３３．４±１９．７周，３．３９ｃｍ）；（３）腹痛腹块（１０例，１９．２±１１．２周，５．０ｃｍ）；（４）贫血（２例，１７．２±９．９周，４．７５ｃｍ）。８／１２例的Ａ０和Ａ１期病例属便血组，并多位于直肠。４１／４７例以高、中分化腺癌为主，其中１５例伴有腺瘤癌变。术前曾作活检的２７例中，１２例未检出癌变细胞。结论四项检查对检出早期大肠癌是有效的，便血是提示早期癌最有价值的症状，加强大肠癌防治宣教，采用瘤灶多点或全瘤活检技术，高度重视大肠腺瘤和不典型增生等癌前病变，将有助于提高早期大肠癌的检出率     

What should nurse teachers be doing? A preliminary study

There is little doubt that the role of the nurse teacher is complex and multifaceted in nature. The apparently conflicting demands of NHS trusts and education in the United Kingdom, at the time of integration of nurse education into the higher education sector, further complicates the role. This recognition underlines the need to capture and measure key aspects of nurse teacher function in order to maximize educational gain. Using a comprehensive literature review, focus group discussions and a small number of individual semi-structured interviews, this preliminary study explored the issue of teacher workload, from the perspective of the principal stakeholders in nurse and higher education. Competing research and clinical practice objectives for nurse teachers are identified against a background of changing health care provision, reduced availability of placements and an increased need for evidence-based practice.

Pneumatosis cystoides intestinii

Zusammenfassung Die Pneumatosis cystoides intestinii (PCI), das Auftreten submuköser oder subseröser, gasgefüllter Zysten in der Wand des Gastrointestinaltrakts, tritt als seltene Erkrankung ohne eindeutige Geschlechtspräferenz vorwiegend in der 3. bis 5. Lebensdekade auf. Atiopathogenetisch werden unterschiedliche Faktoren diskutiert, am wahrscheinlichsten ist eine bakterielle Ursache (Clostridium perfringens) in Verbindung mit einer minimalen Unterbrechung der Mukosaintegrität. Eine pathognomonische Symptomatik gibt es nicht, das klinische Bild reicht von asymptomatischen Zufallsbefunden bis zur Hämatochezie. Die Diagnose wird durch den Nachweis der Gaseinschlüsse mittels Abdomenübersichtsaufnahme und Kolonkontrasteinlauf gestellt. Als Behandlungsmethoden für symptomatische Patienten stehen Sauerstofftherapie, Antibiotikagabe (Metronidazol) und in schweren Fällen die Resektion des betroffenen Darmabschnitts zur Verfügung.

---

Pneumatosis cystoides intestinalis (PCI), a condition involving submucosal or subserosal gas-containing cysts of the wall of the gastrointestinal tract, is a rare entity. It is mostly diagnosed between the third and fifth decades of life without a clear sexual predominance. Different aetiopathogenetic factors are under discussion, the most probable being a bacteriologic cause (Clostridium perfringens) in combination with minimal leaks in mucosal barrier. There are no pathognomonic symptoms; the clinical picture ranges from incidental findings to haematochezia. Diagnosis is based on plain abdominal film and X-ray following barium enema. Methods of treatment in symptomatic cases are oxygen and antibiotic (metronidazole) therapies and, in severe cases, resection of the diseased part of the intestine.

     

Quality of life assessment and HIV infection: A review

In the last few years, survival of patients infected with human immunodeficiency virus (HIV) has been improved because of a decreased incidence of some opportunistic complications attributable to prophylactic treatments and antiretroviral drugs. The impact of these agents should also be reflected in the quality of life (QoL) of patients. We have reviewed this topic with an emphasis on different types of measurements such as Q-TWIST, MOS and the Spitzer score which seem to be most appropriate for this patient population. We do not think that a special type of assessment should be designed for HIV-infected persons. It would be less time-consuming to improve already existing validated scores focusing on HIV infection. QoL in intravenous drug users with HIV should be evaluated more often.
