Comparison and Analysis about Off-indication Use of Psychiatric Drugs in Our Hospital by the Standards of CFDA and FDA / 中国药房

OBJECTIVE:To investigate off-indication use of oral chemical drugs medical orders by the standards of CFDA and FDA,and to compare the differences between the two standards,analyze reasons and rationality of drug use,so as to pro-vide reference for establishing off-indications use management system. METHODS:The oral chemical drugs medical orders of inpatients were analyzed statistically during Jan.-Jun. 2016. Off-label uses was judged according to the standards of CFDA and FDA. RESULTS:Totally 507 oral chemical drugs medical orders were collected,the percentage of off-indications use were in high level,being 58.58% and 55.82% respectively by the standards of CFDA and FDA. The incidence of off-indication use of quetiapine and aripiprazole by the CFDA standards were significantly higher than the results of FDA standards,with statistical significance(P<0.05). Magnesium valproate(54.03%),escitalopram oxalate(10.45%)and quetiapine(10.15%)occupied the top 3 places in the list of constituent ratio. Among off-indication medical orders,7 orders had no evidence-based medicine,ac-counting for 2.36% of total. CONCLUSIONS:Most off-indication medical orders of our hospital could provide the basis and lit-erature support,while there are still a few off-indication use with insufficient evidence. The corresponding management system of the hospital should be formulated to guarantee the medication safety of the patients and legitimate rights and interests of the doctors.

Effect of DRD1, DRD3 gene knockout and double gene knockout on body weight in mice / 中国比较医学杂志

Objective To study the effect of dopamine receptors on neurological and physiological activities. Methods Dopamine D1 receptor gene (DRD1) knockout mice and dopamine D3 receptor (DRD3) gene knockout mice were introduced, and double gene knockout mice were bred in our lab.Seven SPF male mice in each group were used in this experiment.The food intake, water intake, body weight gain for 24 hours were tested on the age of 30 d, 50 d, and 70 d and were compared with those of wild type mice.Results DRD1 gene and DRD3 gene showed significant effect on the body weight in mice in age of 21 day and 35 day, but at the age of 90 day, the differences became insignificant among the mice of various genetypes.Conclusions Dopamine may effect on the foraging and satiety in newborn mice through regulating the hypothalamic-pituitary-adrenal ( HPA ) axis activity, and finally leads to a reduced body weight gain in newborn mice and puppies during lactation.Furthermore, DRD1 gene and DRD3 gene may influence on body weight of newborn mice through regulating mothers’ lactation, lead to a lower body weight at ablactation, and compensatory increase of body weight after ablactation.Our results provide a substantial foundation for studying the function and interaction of DRD1 and DRD3 genes.
