Determination of residual Kryptofix 2.2.2 levels in [F]-labeled radiopharmaceuticals for human use

4,7,13,16,21,24-Hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane (Kryptofix^® 2.2.2) is used in the routine preparation of [¹⁸F]-labeled tracers employed in positron emission tomography (PET) imaging. Confirming the absence of Kryptofix^® in radiopharmaceuticals is a quality control criterion required before they can be released for human use. Analysis of Kryptofix^® levels using the iodoplatinate spot-test can be complicated by false-positive results due to nitrogen containing tracers and/or false-negative results caused by added stabilizers. To overcome this issue, we have developed a universal TLC method for the rapid and reliable determination of Kryptofix^® levels in the wide range of fluorine-18 radiopharmaceuticals we prepare, including complex multi-component formulations.     

Induced abortion in China and the advances of post abortion family planning service

<正>This is a review of current situation of induced abortion and post abortion family planning service in China. Induced abortion is an important issue in reproductive health. This article reviewed the distribution of induced abortion in various time, areas, and population in China, and explored the character, reason, and harm to reproductive health of induced abortion. Furthermore, this article introduces the concept of Quality of Care Program in Family Planning, and discusses how important and necessary it is to introduce Quality of Care Program in Family Planning to China.

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。     

21世纪加强医学生人文素质培养的思考

医学科学从来就是科学知识与人文精神密切结合的一门学科。现代科学技术越来越多地应用于医学研究和医学实践,大大地促进了医学科学的发展,然而也呼唤着更多的医学人文精神的关怀。如何把医学科学知识与医学人文精神有机地结合起来,是我国医学院校教育的重要课题。     

Quality of life as outcome in the treatment of osteoporosis: The development of a questionnaire for quality of life by the European foundation for osteoporosis

The morbidity of osteoporosis is caused by fractures. Vertebral fractures lead to pain and disability and a decrease in quality of life. A Working Party of the European Foundation for Osteoporosis has developed a specific questionnaire for patients with established vertebral osteoporosis. This questionnaire is intended for use in clinical trials. The questionnaire consists of questions and visual analogue scales in the following domains: pain, activities of daily living, jobs around the house, mobility, leisure and social activities, general health perception and mood. The questionnaire has been translated from English into French, German, Italian, Hebrew, Swedish and Dutch. The questionnaire is currently being validated in a multicentre study involving patients with stable osteoporosis and control subjects. Preliminary results indicate that the reproducibility is sufficient and that the questionnaire is able to discriminate between patients with vertebral osteoporosis and control subjects.     

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。
