OBJECTIVE:To analyze the application status quo and the existing problems of the cost - effectiveness analysis (CEA) in pharmacoeconomic study and to propose corresponding suggestions.METHODS:With the published pharmacoeconomic evaluation documents as our target to study,the problems occurred in the application of CEA were analyzed statistically. RESULTS & CONCLUSION:Cost- effectiveness analysis is currently one of the most popular method for the evaluation of pharmacoeconomics,however,many problems can still be seen in its application,therefore,which remains be standardized in its application.

OBJECTIVE:To analyze the research method of the cause of ADR induced by TCM injection and to summarize research achievement.METHODS:Recent published literatures on the cause of ADR induced by TCM injection were reviewed so as to analyze the current research on the cause of ADR induced by TCM injection.RESULTS&CONCLUSION:The research about causes of ADR induced by TCM injection made some progress while there are some limitations.It is suggested to integrate and explore the cause of ADR induced by TCM injection in literatures using mathematical statistics and data mining.

Objective:To understand the health status,influencing factors and spatial distribution of the Chinese floating population and to evaluate the health equity of the floating population.Methods:All the data were collected from the 2017 Migrant Population Dynamic Monitoring Survey in China,binary Logistic regression was used to analyze the factors that might affect the health of the floating population,and the concentration index method was used to evaluate the health equity of the floating population.Spa-tial autocorrelation analyses the spatial aggregation of health status and health equity.Results:The un-healthy rate of the floating population in China was 2.71％.Age and gender show a statistically signifi-cant impact on self-rated health;that is,as age increases,the self-rated health of the migrant population gradually deteriorates,and women are more likely to think that they are unhealthy.Fairness analysis shows that the concentration index of the floating population is 0.021 7,the urban household registration floating population is 0.021 6,and the rural household registration floating population is 0.021 9.It is shown that the fairness of the health status of the floating population is biased towards the high-income class,and the rural household registration floating population's health unfairness is greater than that of the urban household registration migration population.Moreover,Moran's i=0.211 for self-rated health and Moran's i=0.291 for the unhealthy rate indicate that self-rated health has a spatial aggregation trend.Moran's i=0.136 showed the characteristics of spatial clustering,and the two-week prevalence fairness of the floating population was mainly in the northern and southeastern coastal areas.Conclusion:In general,the health status of the floating population in China is relatively good.The main influencing factors of health included gender and age.The central tendency of health inequity is reflected in the south-east coastal and northern regions,which are characterized by poverty.Attention to spatial aggregation is not only helpful to analyze the reasons of floating population,but also to study the health differences between different regions and health-related factors,to improve the overall health level of the whole population.
