ABSTRACT
Objective To develop a core competence evaluation index system for preventive medicine undergraduates.Methods Following the scientific,systematic and applicable principles,we proposed evaluation index system of core competence for professional medical prevention and selected 35 experts for three rounds expert consultation on the index system by using Delphi method.The basic situation,the positive and authority degree of experts and all levels of index weight coefficient were analyzed using SPSS 13.0 software.Results The core competence evaluation index system for preventive medicine undergraduates included six dimensionalities,fifteen secondary indicators and forty-nine tertiary indicators.The six dimensionalities included professional value behavior (0.25),professional knowledge and skills (0.28),basic specialized knowledge (0.20),communication (0.13),information management (0.06) and systems thinking (0.08).Conclusion The establishment of the evaluation system can provide a scientific and objective reference for the evaluation of the core competence of medical students.
ABSTRACT
Anterior shoulder instability is a very difficult issue to treat,especially with glenoid bone defect.When the defect is small,there is little influence on shoulder instability.The larger the defect is,the more influence there will be.Most authors agree that glenoid bone reconstruction should be considered when glenoid bone defect is more than 20％-25％.In this condition soft tissue procedures alone are not enough to provide stability to the shoulder.To date,there is still not an ideal typing of glenoid bone defect.There are many methods of assessing the size of bone defect.Pico system is one of the most common methods,as it is easier and more precise.Numerous surgical procedures have been described to address the bone defect.The Bristow procedure,the Latarjet procedure and the Eden-hybinette procedure are effective and most popular around the world.The Latarjet procedure can provide more bone blocking than the Bristow procedure,and is more popular.The Eden-hybinette procedure dose not need coracoid transfer and then has no damage of normal anatomical structure.But it also lack the hanging effect of the conjoint tendon.After all,each procedure has its advantage and disadvantage in treating anterior shoulder instability associated with glenoid bone defect and should be chosen depending on the characteristics of each patient and the preference of each surgeon.Furthermore,more new and effective treatments are still needed.
ABSTRACT
ve To explore the health effects of the application of colored glass on human health. Methods The factors of indoor environment including the intensity of ultraviolet rays, illumination and temperature, were monitored, and the contents of calcium and phosphorous, the activity of alkaline phosphatase in serum of population working in the rooms decorated with blue glass, dark brown glass and common plate glass respectively were deter-mined respectively. Results Significantly lower levels of calcium and phosphorous in serum, higher activity of alka-line phosphatase in serum were observed in population working in environment decorated with colored glass compared with those in population working in environment decorated with common plate glass. The regression equation revealed that the contents of calcium and phosphorous in serum of population both negatively correlated with the degree of colors of the glass used for decoration of the environment where the waiters and waitress worked. Conclusion Long term living or working in rooms decorated with colored glass might affect the normal contents of calcium and phos-phorous in serum and normal activity of alkaline phosphatase in serum of population in cold area of North China, and might impair human health in a certain degree.
ABSTRACT
0.05). The correlative analysis on the relationship between IQ and those 4 elements contents showed that the correlative coefficients were 0.593 for calcium, 0.384 for zinc, 0.449 for iron and -0.637 for lead respectively, their P values were all below 0.01. Conclusion The children's IQ was positively correlated with the contents of calcium, zinc and iron in hair, and negatively correlated with the contents of lead in their hair.
