Objective To clarify the influence of Ca and P on bone metabolism by investigating theeir effects on proliferation, differentiation and mineralization of osteoblasts (OBs) in vitro. Method OBs were cultured in media with Ca(1, 2,4 mmol/L),P(1, 2,4 mmol/L),Ca:P 1:2 (1 mmol/L Ca+2 mmol/L P), and Ca:P 2:1 (2 mmol/L Ca+1 mmol/L P). Cell proliferation, activity of alkaline phosphatase (ALP), content of osteopontin (OPN) and collagen type I (Col-I) of OBs, and their corresponding mRNA expression were measured. Results Compared with control group,Ca at 4 mmol/L promoted OBs proliferation significanty (P

There are some prevailing problems in the management team,such as low competency,lack of innovative ideas,lack of pioneering spirit,and serious brain drain,etc. Therefore our college has taken measures to pay close attention to the development of our management team and has made remarkable achievements with the help of assement.

AIM: To study the stability on controlled release pellets of Ginkgolides. METHODS: According to the requirement of stability test of appendix XIXC of China Pharmacopoeia (2000 edition, Part Ⅱ), test for influencing factor, accelerated test and samples kept at room temperature were studied, applying similar factor analysis to appreciate the release stability. RESULTS: All the indexes accorded with the standard. CONCLUSION: Controlled release pellets have a good stability.

Objective To investigate effective MSCT perfusion index and evaluate its significance in the renal function of diabetic nephropathy patients.Methods The 64-slice spiral CT perfusion scanning was performed on experimental group with 25 cases dia-betic nephropathy patients and control group with 25 cases healthy volunteers.The index including the dual-renal blood flow (BF), blood volume (BV),mean transit time (MTT),and permeability of surface (PS)were measured.At the same time,the levels of microalbumin and urinary protein (mg/24 h)were quantitated,and the blood urea and serum creatinine were measured on diabetic nephropathy patients one day before and the second day after renal CT perfusion scanning.Results All indexes of renal MSCT per-fusion,which are BF,BV,MTT and PS,were associated with 24 h quantitative urinary protein and fasting blood-glucose.Only BF and MTT were related to microalbumin and in a good correlation with indexes of diabetic nephropathy (microalbumin,24 h quantita-tive urinary protein,and fasting blood-glucose).Within them,the BF value was negatively correlated to the indexes,and the MTT was positively correlated.The area below the ROC curve of BF and MTT was more than 0.8,it indicated the good effect for the in-dexes in diagnosis of diabetic nephropathy.The usage of non-ionic contrast agent in the renal perfusion scanning process has no sig-nificant impact on the measured index values.Conclusion MSCT renal perfusion index can be used to evaluate the renal function of diabetic patients.BF,BV and MTT could be used in prediction,diagnosis and screening of DN patients,among them BF and MTT indexes were the optimal.

Objective To investigate the effect of total quality management of foreign surgical instruments in nosocomial infection control in the sterilization and supply center. Methods The effect before and after the application of total quality management for foreign surgical instruments in the control of nosocomial infection in the sterilization and supply center was comparatively analyzed. Results The results showed that after the application of total quality management for foreign surgical instruments,the onetime passing rate of sterilization and limits of microbial detection of surgical instruments increased significantly compared with that before application.The passing rate after application was significantly higher than before.The difference was significant.The implementation rate of planed surgery depending on foreign surgical instruments was 98.3％,the rate was 92.4％ before application.There was a significant difference before and after application,the nosocomial infection rate after surgery depending on foreign surgical instruments was 0.88％,before the application was 6.50％,there was a significant difference before and after application. Conclusions Application of total quality management of foreign surgical instruments can significantly improve the efficiency of the use of foreign equipment and working efficiency of the operation room,reduce costs and the incidence of nosocomial infection significantly.It should be applied in the management of foreign surgical instruments in the sterilization and supply center.

Objective To investigate the application effect of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center of hospital. Methods The first-time qualification rate of cleaning,packaging and sterility test and incidence rate of nosocomial infection before and after the application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center of hospital.The application effect was comprehensively evaluated. Results The first-time qualification rate of cleaning,packaging and sterility test after the application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center were significantly increased.The incidence rate of nosocomial infection was 1.5％ before and 5.5％ after the application of cleaning packaging of surgical medical apparatus and instruments,the difference was significant. Conclusions Application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center can effectively control the cleaning and packaging quality,guarantee the thoroughness of subsequent disinfection and sterilization,decrease the incidence rate of nosocomial infection caused by poor quality of surgical medical apparatus and instruments.It creates reliable medical environment for patients and obtain good social and economic benefit,which is worthy of wide application.

Objective To investigate the in-vitro transdermal permeability of cyclovirobuxine D ethosomes.Methods Ethosomes,liposomes,saturated aqueous solution and 35.5% saturated alcohol solution of cyclovirobuxine D were prepared.The in-vitro transdermal permeability of different kinds of preparations of cyclovirobuxine D was studied by in-vitro permeation experiments.Results Cyclovirobuxine D ethosomes enhanced transdermal flux rate of cyclovirobuxine D and the enhancement ratio was 8.85,superior to liposomes and saturate alcohol.The dermatic hold-up amount of cyclovirobuxine D in 35.5% saturated alcohol solution,liposomes and ethosomes was in a decreasing sequence.Conclusion Compared with the liposomes,the ethosomes can enhance the transdermal flux rate of cyclovirobuxine D,which could increase the systematic action of the drug.

The goal of medical education is to train good doctors.Only by understanding the trend of medical education development,call medical schools effectively promote educational reform and improve the quality of medical education.In this paper,we analyze the trend of course plans,teaching content,teaching strategies and the evaluation mode of the domestic and international medical education reform and development,introduce the ideas and practices in reform of management system,training pattern,course plans and assessment methods based on the education platform of"mutual promotion of teaching and research,mutual integration of medicine and humanities and simultaneous improvement of knowledge and ability"in Chongqing Medical University.

The non-affiliated hospital’s teaching system in college includes teaching administration system, teaching operation system and teaching quality supervision and evaluation system. It is the significant step for the non-affiliated hospital to assume the clinic teaching duties that constructs the teaching system. The college and hospital should take measures to provide essential guarantee for constructing the teaching system.

Twenty seven patients with obstruction of three branches below popliteal artery were divided into three groups and treated with three different kinds of arterioveinous reversal randomly. The results show that it is better to rebuild ischemic limb circulation with original vein rearterization on the femoral and popliteal planes than to do on the lower deep groups and original great saphenous rearterization for improving symptoms immediately and blood flow at future. It provides a new operation for obstruction of three branches below popliteal artery caused by thromboangiitis obliterans,arteriosclerosis obliterans and other diseases.
