ABSTRACT
OBJECTIVE To provide reference for improving the classification management of prescription drugs and non- prescription drugs in China by learning from the classification management system of prescription drugs and non-prescription drugs in Canada. METHODS The content and experience of classification management system of prescription drugs and non-prescription drugs in Canada were analyzed， and the thinking of the classification management of prescription drugs and non-prescription drugs in China was proposed. RESULTS ＆＆CONCLUSIONS According to the classification of prescription drugs and non-prescription drugs， drugs can be divided into class Ⅰ drugs， class Ⅱ drugs， class Ⅲ drugs， unclassified drugs in Canada. Specific evaluation factors and management requirements have been established for drug classification. Canada has established a set of systematic management systems and technical standards， which has reference value for improving the classification management system in China. It is suggested to further improve the drug classification management system and supporting policies， strengthen fine classification management of prescription drugs and non-prescription drugs and improve classification registration and transformation review standards in China， by learning from Canadian prescription drug and non-prescription drug system and management model.
ABSTRACT
OB JECTIVE To explore the construction of system of pharmacoeconomic evaluation fo r Chinese patent medicine in preventing and treating major chronic diseases. METHODS The problems in pharmacoeconomic evaluation of Chinese patent medicine for preventing and treating major chronic diseases were analyzed. Based on the problem ，the pharmacoeconomic theory ， tools and methods that can be used to systematically evaluate the prevention and treatment of major chronic diseases by Chinese patent medicine were explored to build the relevant pharmacoeconomic evaluation system. RESULTS & CONCLUSIONS Traditional Chinese medicine shows the advantages in the prevention and treatment of major chronic diseases. This unique advantage needed to be explored ，reflected and proved in the pharmacoeconomic evaluation. The pharmacoeconomic evaluation of Chinese patent medicine had made some progress in recent years. However ，there were still deficiencies of theory and methodology in the pharmacoeconomic evaluation for the advantages of Chinese patent medicine in preventing and treating major chronic diseases. It was difficult to truly and comprehensively reflect the value of Chinese patent medicine by simply applying the economic evaluation indicators and technologies of chemical medicine. It is necessary to focus on the unique pharmacoeconomic attributes of Chinese patent medicine ，excavate the economic value indicators of Chinese patent medicine for “preventive treatment of disease ” and playing the self-regulation role of human body ，comprehensively consider the pharmacoeconomic particularity of Chinese patent medicine in respects of research design ，research angle ，target population ，intervention measures and control selection ，research time limit and evaluation method ，etc. Through the use of system modeling ，real-world research and the establishment of Chinese medicinal quality of life scale that reflects the characteristics of TCM ，the economic value of Chinese patent medicine in the prevention and treatmen t of major chronic diseases is reflected comprehensively，so as to reflect the advantage of Chinese patent medicine in preventing and treating major chronic diseases.

ABSTRACT
BACKGROUND:Many internal fixations,such as dynamic hip screw,Gamma screw,proximal femoral nail,angle steel plate,as well as locking proximac femoral plate,are utilized in treating intertrochanteric fractures,especially the dynamic hip screw However,the failure rate is gradually increased.OBJECTIVE:To explore the application and clinical efficacy of total hip replacement for the treatment of elderly intertrochanteric fracture fixation after failure of dynamic hip screw.METHODS:A total of four cases with intertrochanteric fractures were treated by total hip replacement after failure of dynamic hip screw fixation was selected.According to Evans typing,one case were type Ⅱ,two cases were type Ⅲ A,and one case was typeⅢB.Internal fixation displacement could be found at half to 1 year after dynamic hip screw fixation.Because of bone disunion,coxa adducta and pain,the patients could not walk.Sequentially,total hip replacement was performed with 45°abduct angle and10°-15°anteversion angle The clinical efficacy was evaluated by Harris scoring criteria.RESULTS AND CONCLUSION:All the cases were operated smoothly,with 1.5-2 hour operation duration and 400-600 mL blood loss.No case appeared allergic response to bone cement.By 3-12 months follow-up,4 successful operative cases do not appear prosthesis loosening,subsidence and are satisfied with well hip function.The average Harris score were 81 points.The results revealed that application of total hip replacement after the failure of DHS in elderly intertrochanteric fracture fixation,which shortened the time patients stay in bed to reduce complications and improved the hip joint function.

ABSTRACT
Objective To study the dose rate distribution on cultured cell plane and establish a reference dose rate table of in vitro cell line ~(125)I seed irradiator.Methods Thermoluminescence dosimetry(TLD) was used to measure the irradiation dose rate of a single 6711 model(~(125) I) seed with apparent activity of 10.323 MBq in water at point P.Meanwhile,the theoretic value of the irradiation dose rate at point P was calculated with theoretic formula.The difference between the calculated and observed values within 10% was set as standard to analyze the accuracy of the measurement.The irradiation dose rate of a single 6711 model(~(125) I) seed was measured in 1mm-thick polystyrene + water medium at point P.The value was applied to differential or non-differential proof along with the value from water medium to study the effect of 1 mm thick polystyrene on distribution of irradiation dose in water.Finally,by simulating the(~(125) I) seed plane irradiator with nine(~(125) I) seeds,the distribution table of irradiation dose rate on the cultured cell plane was calculated with theoretical formula.Results The observed value(n= 10) of irradiation dose rate with one(~(125) I) seed in water at point P was(0.359?0.023)cGy/h and the calculated value was 0.347cGy/h,the difference was within 10%.The observed value(n=10) of irradiation dose of one(~(125) I) seed in 1mm-thick polystyrene + water medium at point P was (0.350?0.027)cGy/h,which showed no statistical difference from the observed value in water under differential and non-differential proof.The reference table on dose rate distribution for cells exposed to(~(125) I) seed irradiation in vitro was developed.Conclusions 1mm-thick polystyrene gives no significant effect on irradiation dose rate distribution from(~(125) I) seeds in water.A reference table on the dose rate distribution for cells exposed to(~(125) I) seed irradiation in vitro has been developed,which can be used to determine an optimal irradiating strategy for future work.
