Advantages and application of telemetry compared with the traditional methods in safety pharmacology / 中国比较医学杂志

Objective To prove the advantages of telemetry by comparing with the traditional methods in safety pharmacology.Methods To monitor continuously the heart rate, respiratory rate, blood pressure and ECG of Beagle dogs by traditional and telemetry methods respectively, analyze and compare the changes between anesthetized and conscious dogs before and after feeding.Results Maintenance of anesthesia changed significantly the heart rate, respiratory rate, blood pressure and QT interval in the ECG of animals.The changes of physiological indicators in 24 h is not obvious in conscious animals, and showed a certain biorhythm.Compared with the conscious animals, the anesthetized dogs’ heart rate was significantly higher, blood pressure increased significantly, QRS and QTcf interval prolonged significantly, respiratory frequency decreased, heart rate increased significantly after feeding, and QTcf interval extended very significantly.Conclusions Traditional methods in safety pharmacology affect animal physiological indicators such as heart rate, blood pressure, respiratory rate and QT interval, which affect the objectivity of drug evaluation.Using conscious animals by telemetry can reduce these errors, however, the interference from outside should be eliminated.

Progress in research on acceptance strategy coping with chronic pain / 中华行为医学与脑科学杂志

Objective Chronic pain has brought great suffering to patients,as well as a heavy burden to the society.More attention has been paid on the efficiency of psychological intervention as supplementary means.Among the treatments,acceptance strategy shows its superiority and gradually enters people's field of vision.However,researches in this area are still very scarce.This study intends to review relevant research to provide reference to clinical work and research.Methods Theacceptance andchronic pain as the keywords were searched from the American Psychological Association (APA),China National Knowledge Infrastructure (CNKI),Wanfang data from 1994 to 2014 in English and Chinese articles,and the articles were chosen according to the criteria:① chronic pain and its current situation;②acceptance strategy or acceptance-based therapy;③intervention to chronic pain based on acceptance strategy;④to explore the intervention mechanism of aueptance strategy.Results Eventually,7 Chinese articles and 42 English articles were adopted.Conclusion Acceptance strategy shows some advantages in clinical pain improvement:it can significantly improve the psychological and social function of patients,but it is not always efficient in reducing the pain intensity.There are still some limitations in the present study.It is necessary to develop an acceptance-based therapy with Chinese culture to treat the domestic patients.
