ABSTRACT
Objective To evaluate the effect of proper nutritional therapy guided by indirect caloimetry . Methods According to the digitaltable ,70 critically ill patients whose APACHE II >5 were randomly divided into oberserving ( nutritional therapy guided by indirect caloimetry ) and control groups ( nutritional therapy guided by harris-benedict formula),each group 35 cases.The results of nutrition support were analysed .Results TP,MAMC,ALB were higher than that before treatment in oberserving group (all P0.05).Conclusion The nutritional therapy guided by indirect caloimetry by harris-benedict formula have the some nutritional effect in critically ill patients .
ABSTRACT
OBJECTIVE:To discuss how can the pharmacoeconomics be applied in "me-too" drug research and development.METHODS:The current situation of "me-too" drugs,i.e.the advantageous and disadvantageous of "me-too" drug research and development was discussed.Then,the necessity and the application stage of pharmacoeconomics in "me-too" drug research and development,and issues regarding the option of pharmacoeconomic evaluation methods as well as the possible problems and the countermeasures in the application were addressed.RESULTS & CONCLUSION:Pharmacoeconomics can help promote the rationality of "me-too" drug research and development.
ABSTRACT
Objective A new method is researched based on ECG for human identification.Methods Three features of wave feature,wavelet feature,fusion feature were selected as the feature vectors for 35 normal subject ECGs,and correlation coefficient discriminate analysis was used for human identification. Results The other 40 sessions from 35 subjects were used for verifying the accuracy of each feature.They were 82.5%、87.5% and 95% respectively for wave feature,wavelet feature and fusion feature. ECG wavelet feature outperformed ECG wave feature. While ECG fusion feature performed better than either feature. Conclusion The verification experiment demonstrates that the technology of human identification based on ECG is feasible. ECG can be combined with other biometric features such as fingerprint for developing the multi-biometric identification system. The method proposed in this paper is simple,real-time and exact for human identification.
