ABSTRACT
Based on cognitive psychology, the business attributes of port health quarantine, the requirements for team building, the current status of skill training. This article proposes to strengthen the training of port health quarantine skills. Under the guidance of medical licensing examination for public health, it is recommended to enhance the construction of a standardized skill training practice system, establish a basic skill training center and a field operation training site, develop new skill training courses, innovate skills training and teaching methods, and build a team of high-quality skill training teachers, thereby constructing a standardized skill training and practice system for port health quarantine. The preliminary establishment of the skill training system for port health quarantine at Huangpu Customs shows the feasibility and effectiveness of the construction of skill training and practice system.
ABSTRACT
Objective: To study the mechanism of the preventive effects of soybean isoflavones on osteoporosis. Methods: The serum collected from experimental rats given soybean isoflavones extract was added to the culture system of osteoblast cells (OB) isolated from the calvaria of neonatal SD rats. MTT assay was employed to determine cell proliferation. The activity of alkaline phosphatase (ALP) and bone gla protein (BGP) were determined by ALP and BGP Kits. The content of IL 6 secreted by OB was determined by ELISA Kit. Results: Isoflavones could stimulate OB proliferation, elevate the activity of ALP and BGP level. They had no apparent effects on the secretion of IL 6. Conclusion: Soybean isoflavones can promote proliferation and differentation of OB in vitro and have no remarkable influence on bone absorption. The effects of soybean isoflavones on osteoporosis seem to depend on stimulation of bone formation rather than suppression of bone absorption.
