OBEJECTIVE:To establish a rapid and exclusive method for the identification of metronidazole tablets.METHODS:The infrared spectrophotometry was adopted,in which the recrystallization was carried out with the dehydrated alcohol as the solvent and with the highly pure potassium bromide tabletting as the infrared absorption spectrum.RESULTS:The infrared absorption spectrum of the metronidazole tablets was completely in conformity with that of the control substance and the standard spectrum of metronidazole issued in Infrared Spectrum Album of Drugs by State Pharmacopoeia Committee.CONCLUSION:This method is specific,fast and accurate,which can be used for the identification of metronidazole prepa-rations.

The 52-year-old female patient complained of persistent and progressive obstruction in left nasal cavity for more than 1 years. A grey, hard and smooth tumor with telangiectasia, were seen plugged in left post-nostrils and nasopharynx. CT scanning showed a tumor in the left nasal cavity. Post-operational pathologic diagnosis was peripheral nerve sheath tumors of nasal cavity.

OSCE is an examination of objective evaluation of the clinical skills.This article introduced the development of OSCE at home and aboard,and compared the difference of the exam setting in America,England,Canada and China Medical University.The advantages and disadvantages of SP in OSCE were also analyzed.It was discussed that OSCE would be widely applied in China.

BACKGROUND:The biopsy material induced by foreign body is autologous tissue, which, in theory, avoids the role of immune rejection and destruction faced by non-autologous implants. This biology advantage has no way to comparison by synthetic and de-cel ular materials.
OBJECTIVE:To explore a biotube consisting of autologous cel s and extracel ular matrix and to evaluate its structure and mechanical features.
METHODS:The biotubes were prepared by embedding silicon rods as a mold intraperitoneal y. Specimens were analyzed by mechanical tests, histological observation and superficial study.
RESULTS AND CONCLUSION:It was easy to excite the biotubes prepared by embedding silicon tube
intraperitoneal y. The biotube mainly included col agen-rich extracel ular matrices and myofibroblasts appearing as elongated cel s with circumferential or longitudinal orientations. At 1 month of embedding, the wal was 70-250μm in thickness and had burst strength of (1 100±187) mm Hg (1 mm Hg=0.133 kPa), with perfect sewability. The biotubes, which possess the ability for wide adjustments in their shapes, are composed of autologous cel s and extracel ular matrices, and are an ideal graft for tissue engineering because they avoid immunological rejection and have sufficient mechanical strength.

Objective To explore the application of heteroscedastic time series model to the analysis of data of infectious diseases.Methods ARIMA and AR-GARCH models were used to fit the incidence of gonorrhea.Results The time series in this study,which was heteroscedastic significantly,finally was well fitted by AR(1)-GARCH(0,1) model through model selecting.Conclusions AR-GARCH model is suitable for analyzing heteroscedastic time-series data of infectious diseases.

Objective To analyze the descending trend of maternal mortality ratio (MMR) and its related influencing factors in order to improve the descending speed of MMR. Methods The influencial factor analysis and u test were made on data collected from 232 rural counties of eight provinces in China. Results MMR had shown remarkable reduction from 1995 to 2000, a drop by 51.33%. However, there was still a gap if compared with the ratio of the whole country. Major causes influencing the descending speed of MMR include the high speed of economic development, more expenditure of health, quality of maternal service, such as the ratio of hospital delivery, cleaning delivery, prenatal and postnatal health care. Conclusion In order to accelerate the descending speed of MMR, attempts to increase the improvement speed of maternal health care, quality of maternal service and more expenditure of health should be made.

The authors compared the purpose,and the main content of three international standards in medical education developed by the Institute for International Medical Education (IIME), World Health Organization Western Pacific Regional Office (WHO/WPRO), and World Federation for Medical Education (WFME) respectively. The IIME's standard is deferent from the others. The IIME's standard contains seven broad educational outcome domains and 60 items in the domains. The purpose of IIME's standard is to improve the common core competency of individual medical graduates of each medical school in the world, and the standard focuses the outcome of medical education and belongs to summative individual evaluation. The WHO/WPRO's and WFME's standards are quite similar. They define the standards across nine broad areas of medical schooling divided into 38 sub-areas. The ultimate goal of the WHO/WPRO's standard is to encourage national governments to adopt a quality assurance process in medical education. The aim of the two standards is to promote the quality assurance of medical schools. Both of the two standards focus the whole process of medical schooling and medical schools, and belong to formative evaluation.

This project studied the historical and the present situation about the personnel training model in medical education and its structure. It reestablished the objectives of the medical education and the standards of the training, modified the training program, and the curriculum system, and set up the new teaching plan and syllabus. Through three years of research and implementation, the training model of widening the basic science, breaking into three stages, integrating the courses, optimizing three phases, activating teaching methods and total adaptability had been constructed.And the project had been studied, applied and spread cooperatively with 16 Chinese medical schools.

Objectives:To learn about the attitudes toward the "Global Minimum Essential Requirements(GMER) in medical education" between Chinese doctors and graduates from the same medical university and to offer reference for spreading GMER in China.Methods: To investigate the subbjects using a questionnaire describing the related abilities of GMER.Description,rank test,multivariate analysis of variance and factor analysis are applied in data analysis.Results: In general,there are different attitudes toward GMER between doctors and graduates.13 of 23 items have statistical significance in scores between groups.The proportion of person considering every item as important or very important among doctors is higher than that among graduates.There is statistical significance between groups on the transformed score in 7 domains of GMER.The domain of topmost score is "clinical skills",and of the lowermost one is "community health & health system".Conclusions: Doctors and graduates both accept GMER.They both pay attention to occupational skills,but ignore the public health.Doctors think much of basic knowledge,while graduates are short of the cognition on "Information Management".
