Objective To achieve systemic and efficient management of the hospital variety of medical equipment,simplify the day -to -day inspection of work. Methods The software part's development used Delphi7.0 and SQL Sever 2000 separately as the onstage development kit and the backstage database; the hardware part,Anti-metal Mifare1 card as the RFID tag,MSR-100 and HDT-3000 as reader were used. Results Test to the system indicates that in the 0～40 mm scope,both of the readers can accurately read and write the tag which adheres to the metal surface,and almost without direction limit. Conclusion Compared with ordinary data bank administration software,this system not only has the basic function such as data's increase,deletion,revision,preservation,backup and restore and so on,but also realizes information exchange between the electronic tag and the database through the serial port and the corresponding submodule; The handle-reader's application especially makes the complicated daily inspection easy and readily achievable,which improves maintenance efficiency,meets the needs of efficient dynamic medical equipment management.

OBJECTIVE:To give some information for developing,using and integrating the available resources of R&D efficiently and accelerating the R&D of new drugs.METHODS:Using scale economic and imitational innovational theory,the current situation of R&D of new drugs at home and abroad were dicussed in terms of resource organization and selection of topic.RESULTS&CONCLUSION:Development of scale economics can benefit the R&D of new drugs in China and imita?tional innovation is a practical way in the present stage.

OBJECTIVE:To provide references for the reformation of private drug wholesale enterprises in Chi?na.METHODS:The private drug wholesale enterprises in China were analyzed in respect to its strength,weakness,opportuni?ties and threats.RESULTS&CONCLUSION:Losing no chances for the reforming of the private drug wholesale enterprises in China is helpful to its development.

BACKGROUND: Avascular necrosis of the femoral head occurs in the hip joints at high load-bearing areas, it is a special form of aseptic bone necrosis. Bone marrow-derived mesenchymal stem cells may have an excellent repair effect for the necrosis of femoral head. OBJECTIVE: To understand bone marrow mesenchymal stem cell transplantation for treatment of early avascular necrosis of the femoral head, and to lay a foundation for further study. METHODS: Taking avascular necrosis of femur head, femur head necrosis, osteonecrosis, bone marrow mesenchymal stem cells, mesenchymal stem cells, multipotent stem cells in English as search terms, Pubmed database from January 2000 to April 2009 was retrieved; Taking avascular necrosis and bone marrow mesenchymal stem cells in Chinese as search terms, CNKI database from January 1989 to April 2009 was searched, Literatures were limited to English and Chinese languages. Inclusive criteria: Study of the biological characteristics and functions of bone marrow mesenchymal stem cells, the etiology and pathology of avascular necrosis of femoral head, bone marrow mesenchymal stem cell transplantation for treatment of avascular necrosis; Exclusive criteria: duplication of documents. RESULTS AND CONCLUSION: More than 800 literatures were screened out by computer search, according to inclusive and exclusive criteria, 38 documents of which were involved for analysis. Marrow mesenchymal stem cells can differentiate into chondrocytes, osteocytes and dipocytes under suitable cultural condition. With the development of stem cell engineering, marrow mesenchymal stem cell transplantation becomes an effective method for repairing osteonecrosis. This article describes the cause and the pathology of avascular necrosis of the femoral head, analyzes the theory basis for the treatment of avascular necrosis of the femoral head with marrow mesenchymal stem cell, and verifies its effect through comparing both animal and clinical experiments of this aspect at home and abroad, with the hope of seeking a better treatment.

Objective:To develop the adolescent's family Satisfaction scale(AFSS)and test the reliability and validity of it. Methods:Obtain the structure and items on the basis of an open structure questionnaire survey and literature review,and then 1253 middle school students were tested with AFSS to test the reliability and validity of the scale.Results:The AFSS consists of 42 items and reflects three factors including family circumstance, the way of families fostering the child, communication and understanding of family. The test-retest reliability ranged from 0.882 to 0.972,and the correlations between factors and the whole questionnaire ranged from 0.899 to 0.906,which all met the criteria for adequacy of fit.Loading of the items were from 0.458 to 0.753, which explain 51.532%of the total variance.Conclusion:The AFSS is a reliable and valid scale for assessing the family satisfaction of adolescents.

Objective: To investigate the relationship between arterial stiffness and variability of blood pressure (BPV) in senile patients with hypertension.
Methods: A total of 234 senile patients with hypertension were enrolled. The patients were examined by 24h ambulatory blood pressure monitoring (ABPM), BPV was identified by the standard deviation (SD) of blood pressure value. Based on increased percentage of baPWV, the patients were divided into 4 groups: Normal artery group, n=44, Mild arterial stiff group, n=72, Moderate arterial stiff group, n=78 and Severe arterial stiff group, n=40. The 24h ABPM results, BPV, biochemical indexes and their relationship to baPWV were compared among different groups.
Results:①The HDL-C level and 24hDBP, dDBP, 24hSBPSD, 24hDBPSD, dSBPSD, dDBPSD, nDBPSD were significantly different among each group, all P<0.05.②The increased percentage of baPWV was positively related to the age and 24hSBPSD, 24hDBPSD, dSBPSD, dDBPSD, nDBPSD, while negatively related to HDL-C level, all P<0.05.③The age and 24hSBPSD, 24hDBPSD, dSBPSD were the independent risk factors for baPWV elevation.
Conclusion: The arterial stiffness was closely related to BPV in senile patients with hypertension.
