Angiosteosis is associated with increased vascular stiffness and leads to clinical manifestations such as high blood pressure and heart failure,which increases the risk of cardiovascular morbidity and mortality.Angiosteosis is considered to be ectopic deposits of calcium phosphate crystallization in the form of hydroxyapatite in cardiovascular tissue.However,the mechanism of angiosteosis is not yet clear.The pathophysiologic process of angiosteosis is similar to normal bone mineralization.Matrix vesicles (MV) play an important role in bone mineralization.Researches confirmed the existence of MV in the calcified arteries under the microscope.Angiosteosis is widely found in clinical diseases,so the studies of the mechanism of angiosteosis and the role of MV in angiosteosis are of great significance.

Successful implementation of TCM scientific research projects is the main motive force of the development of traditional Chinese medicine. With the establishment of public welfare industry research in 2006, TCM scientific research projects have obtained increasing investment funds from the central budget. Therefore, how to organize TCM research projects becomes a new task for department of scientific research management. Through years of work experience in scientific research management, the authors made an analysis of the special project management paradigm in Chinese medicine industry from the basic situation of TCM industry, investment, organization and management, and appraisal mechanism.

Objective Study the common symptoms of sub-healthy people. Methods Study the 59 symptoms of the 1 828 cases of sub-healthy people that the study of DME Research on TCM Syndrome of Sub-health State had collected. Select the symptoms by analysis of percentage, mean, correlation and discriminance. Finally, find out the symptomatic characters of the sub-healthy people by the data mining method of decision tree. Result There were 26 variables selected from the 56 symptoms. The result of decision tree showed that low quality of sleep, fatigue, dry in throat, acid and distend in eyes, ache, emptiness in heart had greater relations with sub-health. Conclusion Low quality of sleep, fatigue, dry in throat, acid and distend in eyes, ache, emptiness in heart are the symptoms that have greater relations with sub-health.

?Objective: To study the stress distribution of one segment type mono dowel implant with various length and diameter in alveolar bone. Methods: The thickness of cortical bone is 1~2 mm, implant was in close contact with alveolar bone directly. Implants with root length of 10,12,13 and 14 mm, cast diameter of 3.6, 3.7, 3.8, 3.9 and 4.0 mm, corona tall 4 and 9 mm were put into a bone model with alveolar bone. 200 N force was loaded in vertical, 45? oblique and 45? oblique of non center. CT and 3D FEM were used to study the stress distribution and selected the morphology of alveolar bone from first molar of lower jaw and an incisor of maxillary. Results: There was an area of stress in the boundary of the cortical and cancellous bony tissue,horizontal hole. The main region of stress was at the cancellous. Thickness and shape of alveolar bone could affect the distribution of stress. The maximal Von Mises Stress was always in the boundary of cortical and bone that contacted with implant. Higher elastic modulus of bone around the implant had higher stress in cortical stress . Conclusion: The stress of cortical and cancellous bone can be depressed to rise elastic modulus of implant.

砄bjecat:To study the correlatiom between stress and structure of one piece spiral implant.Methods: The morphology of alveolar bone was selected by CT around the first molar of mandible and around the incisor of maxilla of a healthy man in the position of normal occlusion. Cortical bone with the thickness of 1~2 mm was used to make the alveolar bone model. The one piece spiral implants with root, in the shape of cylinder, length of 10,12, 13 and 14 mm, corona height of 4 and 9 mm,diameter of 3.6,3.7, 3.8,3.9 and 4.0 mm were prepared respectively. The implants were put into the alveolar bone models and a load of 200 N was applied vertically, or 45 ℃ obliquely or 45℃ non center obliquely. The stress on the implants was measured and studied with 3D FEM. Results:The stress on the implants was inversely correlated to the length and diameter in the place of front teeth and molars except non centeraly obliquely loading to molar. The greatest stress was found around the neck of the implants. The distribution and intensity of the stress were related to the way of loading and the elastic modulus of bone. Conclusion:The length and diameter of one piece implant are the factors correlated to the stress on the implant and surrounding bone.
