医学生素质教育中几对关系的处理

当医学素质教育中广博、个性、创新等观念日益被教育者和教育对象接受的同时，常常又容易陷入另一个误区，即盲目接纳、肯定这些观念，高没有对其进行审慎、辩证的思考，文章通过素质教育中几对观念的辨析，以期对此形成客观、全面的认识。     

均一吸收体中SPECT重建多解性的探讨

通过对重建图像噪声特性的分析，间接证明ＳＰＥＣＴ的解具有多样性。分别用ＴｒｅｔｉａｋＭｅｔｚ、Ｇｕｌｂｅｒｇ、富谷武浩等推导的３种等价重建方法和Ｂｅｌｉｎｉ等推导的重建方法，经计算机模拟重建衰减均匀分布的图像，先预置相同的重建图像的空间分辨率，再比较它们的噪声特性。两种方法重建图像的噪声分布：前者近图像边缘时增大，而后者减小，从而间接证明在假定均匀衰减条件下，ＳＰＥＣＴ的重建有多解性。     

Late Effects of Childhood Acute Leukemia and Its Treatment

Late effects of childhood acute leukemia and its treatment were studied in 766 patients (684 ALL, 73 ANLL, and 9 others) in Japan who had remained in remission for more than 1 year after their first complete remission. Delayed adverse sequelae involve a wide variety of organs and their functions. Short stature was present in 2.61%, obesity in 3.79%, abnormalities of growth hormone secretion in 1.5%, delayed secondary sex characteristics in 1.5% of males and 0.6% of females, motor disturbances in 1.17%, sensory disturbances in 0.91%, intellectual and learning disabilities in 2.48%, abnormal findings in routine neurologic examinations in 1.31%, EEG abnormalities in 4.30%, brain CT abnormalities in 5.09% and cardiac dysfunction in 1.07%. Various other disorders were seen in 20 patients. Many of these delayed adverse sequelae are caused by or related to central nervous system prophylaxis and systemic combination chemotherapy. The results suggest that it is needed to improve therapeutic methods through the stratification of patients by risk factors and detailed analysis of prognostic factors. Moreover it is important to render medical and psychosocial support to long-term survivors of childhood leukemia through interactions between the patient, parents and medical staff.     

论医院质量管理推行ISO9000族标准的必要性

为了迎接医疗市场的竞争和挑战 ,医院将应用于工业企业的ISO90 0 0族标准引入到医疗服务领域。它通过严格的过程控制 ,使医院实现了质量管理制度健全化、系统化、合理化 ,大大减少了服务中的差错 ,全面提高了服务质量 ;通过工作程序化及持续改进 ,改善了医务人员的工作环境 ,提高了医院运作效率和运营效益。本文从现行的质量管理的不足分析入手 ,从八个方面阐述医院质量管理推行IS0 90 0 0族标准的必要性 ,以此来说明医院的质量管理采用ISO90 0 0族标准 ,将会使医院的质量管理有一个质的飞跃。事实证明通过认证的医院已从中收益。     

Developing and running an EQA scheme in diagnostic histopathology

External quality assessment (EQA) schemes in histopathology form a key part of laboratory quality management, but their principal function is educational. ‘Test’ material is circulated to participants, who evaluate the material following their normal practice and return responses to an organizing laboratory for collation and evaluation. The test material must be representative of the routine workload, but not mundane. Unlike histopathology slide clubs, objective, quantitative, personal feedback for each participant is vital to ensure unambiguously the identification of areas requiring CPD. The objective evaluation of textual responses in EQA is problematic, but various approaches have been used successfully. The participants are individuals, not laboratories, so confidentiality is paramount. Mechanisms to investigate persistent substandard performance must exist, but should be used very rarely; self-improvement is the usual route to protecting standards of patient care.     

18F-FDG PET/CT显像正常腹部消化器官的标准摄取值分析

目的分析^18F-脱氧葡萄糖（FDG）PET/CT显像正常腹部消化器官标准摄取值（SUV）的变化范围.方法60例要求行PET/CT检查的健康人,按体重7.77 MBq/kg静脉注射^18F-FDG,PET采集为三维模式,每个床位3 min.对腹部肝、胆囊、脾、胰腺、胃、盲肠、结肠和直肠进行半定量分析,各器官的SUV由横断面测量,准确定位时参考同机CT.结果正常腹部消化器官^18F-FDG摄取有较大差异,其中摄取较高者SUV平均值（SUVavg）依次为直肠、肝、乙状结肠、回盲部和脾、升结肠,SUV最大值（SUVmax）依次为直肠、乙状结肠、肝、回盲部、升结肠、脾.结论PET/CT显像能较好地识别腹部消化器官;熟悉正常腹部消化器官^18F-FDG摄取的差异,对判读图像十分重要.

Views of problem drinking among Native American,Hispanic, and Anglo children

Native American, Hispanic, and Anglo sixth graders reacting to an example of teenage problem drinking expressed similar beliefs and attitudes in many respects. However, Native American children viewed the problem as less serious, subscribed more to a disease theory of alcoholism, attributed less causal responsibility to the individual, and adopted a less aggressive approach toward treatment than did Hispanic, and especially Anglo, children. Their less conventional value orientations accounted for all these differences except their stronger endorsement of a disease theory of problem drinking.     

重庆市正常人群肠道双歧杆菌的定量调查

本文介绍了一种双歧杆菌的选择鉴别培养基,并用该培养基对重庆市正常人群肠道双歧杆菌进行了定量分析,进而确定了正常值,为进一步研究双歧杆菌与人类的健康和疾病以及生态学防治提供了科学依据.同时也显示了正常人类肠道中双收杆菌的含量与年龄及性别无显著差异.
