OBJECTIVE:To provide reference for rational use of narcotics drugs in the clinic. METHODS:A total of 5 841 prescriptions of narcotic drugs in our hospital from Jan. 2012 to Dec. 2013 were selected as subjects. The utilization of drugs was an-alyzed statistically using DDDs,DDC and DUI as index. The situation of pharmacists prescriptions dispensing was analyzed with missing rate of unqualified prescriptions as an indicator. RESULTS:7 narcotics drugs DUI≤1.00 in 2012. 9 narcotics drugs DUIs≤1.00 in 2013. The highest missing rate of unqualified prescriptions was 9.33% in the inpatient pharmacy in 2013. The amount and DDDs of Morphine hydrochloride injection,Morphine sulfate sustained-release tablet and Oxycodone sustained-release tablet all in-creased in 2013,compared to in 2012;DUI of all morphine preparation were >1.00. DUI of Codeine phosphate tablet and Bucin-nazine tablet were decreased from 1.64 and 1.11 in 2012 to 1.02 and 0.74 in 2013,tending to be reasonable. The amount and DDDs of Sulfentanyl injection,Remifentanil injection and Fentanyl patch all in 2013,compared to in 2012. CONCLUSIONS:The utilization of narcotics drugs in our hospital basically tend to be rational,but still many deficiencies exist. We should strengthen in-tervention and management on the the utilization of narcotic drugs further.

Allergic diseases such as allergic asthma, allergic der-matitis, allergic rhinitis, are polygenic diseases, involving the interaction between the environment, genes and immunity. In the past few decades, the incidence rate of allergic diseases in-creased predominantly and influenced the quality of people's lives seriously, so looking for new targets for the prevention and treat-ment of allergic diseases and drugs with less adverse reaction be-comes a hot topic for researchers. MicroRNAs(miRNAs)are a class of endogenous non-coding small RNAs that mediate nega-tively posttranscriptional regulation of gene expression by targe-ting specific mRNA sequences to inhibit the translation of mR-NAs. They are widely involved in the biological processes of cell differentiation, immune response and tumor development. The study shows that miRNAs can control the occurrence and devel-opment of allergic diseases. Studying the regulatory role of miR-NAs in allergic diseases has important implications for exploring the immunopathological mechanisms and discovering new thera-peutic targets of drugs.

Objective:To investigate the role of epidermal growth factor receptor (EGFR)in the regulation of B[a]P-induced silent information regulator 1 (SIRT1 ) activation in the human bronchial epithelial cells (BEAS-2B),and to clarify the relationship between EGFR/SIRT1 signal transduction pathway and the occurrence and development lung cancer.Methods:The prediction analysis of transcriptional factor binding sites of SIRT1 was performed by MOTIF SearchTM software.The primary cultivated BEAS-2B cells were divided into control group (without B[a]P exposure)and B[a]P groups (the cells were exposed to B[a]P for 6,12,24,48 h).RT-PCR and Western blotting method were carried out to detect the EGFR mRNA and protein expression levels.The BEAS-2B cells transfected with SIRT1 promotor luciferase reporter gene plasmid were treated with human epidermal growth factor (hEGF)and Genistein (tyrosine protein kinase inhibitor)for 24 h,the morphology of BEAS-2B cells was observed by inverted microscope, and luciferase reporter assay was used to test the SIRT1 transcriptional activity.The human lung tissue biopsies were acquired and the immunohistochemical analysis was used to determine the EGFR protein expression level.Results:The transcriptional factor binding sites of SIRT1 contained EGF, 2Fe-2S and vWF.Compared with control group,the expression levels of EGFR mRNA in B [a]P groups were increased in a time-dependent manner,and reached the peak at 12 h (P < 0.05);the EGFR protein expression levels were also increased (P <0.05).The SIRT1 luciferase activity in hEGF group was increased compared with control group (P <0.05);when hEGF and B[a]P worked together,the SIRT1 luciferase activity was increased even further (P <0.001). The cells showed arrangement and morphologic changes gradually when the B[a]P concentration was above 30 μmol · L-1. Genistein (30 μmol · L-1 )inhibited the increase of SIRT1 luciferase activity induced by B [a]P ,and there was significant difference compared with control group (P <0.05).The immunohistochemistry results showed that EGFR expression level in lung cancer tissue was higher than that in normal lung tissue (P < 0.001).Conclusion:EGFR can regulate the B [a]P-induced SIRT1 expression in BEAS-2B cells,and to cause lung chronic inflammation;EGFR/SIRT1 signal transduction pathway may play a role in the occurrence and development of lung cancer.

Aim To investigate the effect of ketamine plus fluoxetine on depressed behavior and the expres-sion of neuronal nitric oxide synthase (nNOS)and CA-PON in prefrontal lobe of mentally depressed rats at different time points,so as to study the possible mecha-nism of ketamine plus fluoxetine inducing antidepres-sant behavior.Methods Healthy adult male Sprague-Dawley rats,aged 2.5 ~3 months,weighing 220 ~270 g,were induced as the rodent model of depression by chronic unpredictable mild stress (CUMS).After the models of depression were established,96 of CUMS modeling successfully depressed rats were selected. Then they were randomly divided into four groups (n =24 each):the depressed group (group D,untreated group),ketamine group (group K,treated with intrap-eritoneal injection of ketamine 1 0 mg·kg -1 once a day for 3 days or 7 days),fluoxetine group (group F,trea-ted with gavage of fluoxetine 1 .8 mg·kg -1 once a day for 3 days or 7 days),or ketamine plus fluoxetine group (group KF,treated with intraperitoneal injection of ketamine 1 0 mg·kg -1 plus gavage of fluoxetine 1 .8 mg·kg -1 once a day for 3 days or 7 days).Open field test and sucrose preference test were performed 1 day before depression model was established,and 1 day before and after treatment.The rats were sacrificed 1 day after the last test for determination of the expres-sion of nNOS and CAPON protein (using immuno-his-tochemisity)and mRNA (by RT-PCR)in the prefron-tal lobe.Results After the models of depression were established,the total distance,rearing number and the sucrose preference percentage (SPP)were decreased significantly compared with those before (P <0.05). There was no significant difference among all groups in the total distance,rearing number and the SPP before treatment (P >0.05 ).Compared with groups D and F,the total distance was prolonged,the number of rea-ring and SPP were significantly increased,the expres-sion of nNOS protein and mRNA was down-regulated and the expression of CAPON protein and mRNA was up-regulated in groups K and KF,with 3 days’treat-ment (P <0.05).Compared with group D,the total distance was prolonged,the number of rearing and SPP were significantly increased,the expression of nNOS protein and mRNA was down-regulated and the expres-sion of CAPON protein and mRNA was up-regulated in groups K,F and KF with 7 days’treatment (P <0.05).Compared with group F,the total distance was prolonged,the number of rearing and SPP were signifi-cantly increased,the expression of nNOS protein and mRNA was down-regulated and the expression of CA-PON protein and mRNA was up-regulated in group KF with 7 days’treatment (P <0.05).Conclusion Co-administration of antidepressant fluoxetine with ket-amine may induce a more pronounced antidepressant activity than treatment with each antidepressant alone and it can shorten the time to improve the depressive state through promoting the expression of CAPON and inhibiting nNOS activity in the prefrontal lobe of men-tally depressed rats.
