ABSTRACT
OBJECTIVE:To provide reference for rational use of second class of psychotropic drugs in the clinic. METHODS:The second class of psychotropic drugs in outpatient department of our hospital during 2012-2015 were analyzed retrospectively in respects of the number of common drugs prescription,distribution of gender/age/disease diagnosis,DDDs and DUI,etc. RE-SULTS:During 2012-2015,second class of psychotropic drugs in outpatient department of our hospital accounted for 25.09%of to-tal prescription amout. The drugs with high use frequency were alprazolam,clonazepam,lorazepam and estazolam,accounting for 93.10% of total prescription amount of second class of psychotropic drugs. The proportion of male to female was 1∶1.50;the pa-tients aged 19-35 years old took up the biggest proportion,accounting for 34.62%. The proportion of schizophrenia prescription was the highest,accounting for 45.17%. DDDs of alprazolam was the highest,being 742 141.67;its DUI was 1.075;DUI of oth-er drugs was lower than 1.0. CONCLUSIONS:The use of second class of psychotropic drugs is basically reasonable in our hospi-tal. Guiding principles of Clinical Application of Psychotropic Drugs should be implemented strictly and continously to avoid abuse of second class of psychotropic drugs.
ABSTRACT
Objective To investigate the relationship between the serum concentrations of brain derived neurotrophicfactor (BDNF) and its G196A polymorphism in the amphetamine induced-psychosis inpatients.Methods The cross-sectional study included 233 amphetamine abuses and 110 healthy participants who served as controls.The serum concentration of BDNF was measured by sandwich ELISA,and the genotype of BDNF G196A polymorphism was determined used polymerase chain reaction (PCR) techniques.The data were analyzed using SPSS 12.0 statistics software.Results The serum concentration of BDNF in case group((205.81±75.36) pg/ml) were significantly higher than that in control group((95.04±31.63) pg/ml;t=15.02,P＜0.01).There was no significant difference about the BDNF serum concentrations between the inpatients with the amphetamine induced psychosis and the inpatients with the amphetamine abuse (P＞0.05).The BDNF serum concentration showed no significant difference in the genotype distributions and allele frequencies (P＞0.05).The genotype distributions and allele frequencies of BDNF G196A showed no significant difference among three groups(P＞0.05).Conclusion The BDNF serum concentration is correlated with methamphetamine abuse,while the BDNF G196A gene polymorphism may not be associated.
ABSTRACT
The effect of GABA ergic system in the brain in mediating convulsions induced by quinolinic acid (QA) was studied. Muscimol,an agonist of GABAA-receptor, and aminooxyacetic acid (AOAA),an inhibitor of GABA transami-nase(GABA-T) ,and alprazolam which increased the affinity of GABA-receptor as it binds with benzodiazepine-receptor, were used to increase GABAergic function in the brain. Results showed that the above substances antagonized QA-induced convulsions. In contrast, bicu-culline,an antagonist of GABAA-receptor, and 3-mercaptopropionic acid (3-MP), an inhibitor of both GABA synthesis and its release, were used to decrease GABA ergic function in the CNS. They were found to potentiate QA-induced seizures. All these results suggest that GABA ergic system in brain plays an important role in modulating QA-induced convulsions.
