BACKGROUND:It is important to produce and save a large amount of high-activity feeder cel s for the culture of human embryonic stem cel s.
OBJECTIVE:To establish the optimal method for isolation and culture of Kunming mouse embryonic fibroblasts, and to evaluate the feasibility of preparing feeder layers for culture of human embryonic stem cel s.
METHODS:Embryonic fibroblasts were isolated and cultured by different concentrations of trypsin from Kunming mouse fetuses in vitro. The biological characteristics and growth rule of mouse embryonic fibroblasts were investigated, and then the feeder layers for human embryonic stem cel s culture were produced. The growth of human embryonic stem cel s on the prepared feeder layer was tested.
RESULTS AND CONCLUSION:The optimal fetal age for preparing Kunming mouse embryonic fibroblast feeder layer was 13.5 days. Kunming mouse embryonic fibroblasts at different concentrations grew wel with high purity and active proliferation by trypsin digestion method. There was no significant difference in the survival rate of cel s after cryopreservation for 2 weeks, 1 month, 3 months and 6 months. The cel s were proliferative from the second to fourth passage and declined sharply after the fifth passage. Human embryonic stem cel s which grew on Kunming mouse embryonic fibroblasts feeder layers were stil to remain the typical undifferentiated morphology and were strongly positive for alkaline phosphatase and periodic acid-Schiff after long-term subculture. The
mouse embryonic fibroblasts can be used as the stable and high-quality feeder cel s for human embryonic stem cel s.

Objective To collect the information about the types and clinically-used materials for fixed partial dentures, and evaluate the current conditions and characteristics of fixed partial dentures in Shanghai. Methods Three municipal public hospitals and two private commercial dental labs in Shanghai were served as sample units. The data of fixed partial dentures from January 2005 to December 2007 were retrospectively analysed. The number, type and material of dentures of each year were observed, and the proportion of different types and materials of dentures were analysed. Results From 2005 to 2007, the total number of fixed partial dentures gradually increased year by year, and porcelain fused metal crowns accounted for the largest proportion. The application of noble crown in public hospitals increased annually, and the increase rates were 13.85% in 2005 to 2006 and 30.86% in 2006 to 2007, respectively, while the application of casting basic metal full crown decreased annually. Computer-aided design and computer-aided manufacture (CAD/CAM) fixed partial dentures (CAD/CAM crown) and implant dentures occupied a tiny percentage of total fixed partial dentures in public hospitals and privated dental labs, while both had a remarkable increase trend in number between 2005 and 2007 (227.78% and 53.01%, respectively for 2005 to 2006, and 120.34% and 27.41%, respectively for 2006 to 2007). Conclusion Fixed partial dentures are the most common prostheses for tooth defect, and are characterized by the growing application of advanced techniques and high-quality materials.

Objective To investigate the resistance of Acinetobacter baumannii to clinical common antibiotics and new drug tigecycline. Methods Six hundred and two Acinetobacter baumannii isolates were collected from 2008 to 2009 in four teaching hospitals in Zhejiang province. Agar dilution method was used to detect the resistance of 13 clinical commom antibiotics, polymyxin B and tigecycline. Homology analysis of 24 multi-drug resistant Acinetobacter baumannii strains was used to investigate the relationship of each strain with the method of pulsed field gel electrophoresis. Results From 2008 to 2009, the Acinetobacter baumannii isolates of four teaching hospitals in Zhejiang province were mainly isolated from respiratory specimens with the number of 277 (86.0%) strains in 2009, the number of blood samples decreased from 15 (5.4%) strains in 2008 to 5 ( 1.5% ) strains in 2009, and there were no obvious change in other specimens. Acinetobacter baumannii strains were resistant to 13 clinical common antibiotics at different degree, fluctuated from 35.0% to 85.0%. Compared with the resistance in 2008, levofloxacin and tobramyxin decreased 0. 9% and 9.0% in 2009, respectively. However, the resistance of other antibiotics increased at different degree, the resistance of ceftriaxone and cefepime increased about 10.0%, and the resistance of imipenem and meropenem increased to 74.2% (239/602) and 70.8% (228/602) in 2009,respectively. Acinetobacter baumannii showed high resistance to tigecycline with the percent of 78.9% (475/602), while it was only 3.7% (22/602) for polymyxin B. There were six cloning types among the 24 Acinetobacter baumannii isolates, and the most common type was type A with the percent of 50%.Conclusions The resistance of tigecycline makes the situation of nosocomial infectious more serious. It is necessary to control the transmission of multi-drug resistant Acinetobacter baumannii immediately.
