Objective To study the small intestinal absorption patterns of glimepiride in rats. Methods A rat model of small intestinal absorption in vivo was employed in this study. The small intestinal absorption rate of glimepiride was detected by high performance liquid chromatography. Results At the low and high concentrations of glimepiride, the average small intestinal absorption rates were 0.233 6 h -1 and 0.217 8 h -1 , respectively. Conclusion The small intestinal absorption pattern of glimepiride might be passive diffusion.

OBJECTIVE:To provide reference for development of PIVAS.METHODS:Based on the practical condition of our hospital,the necessity of PIVAS and several key problems in the implementation process were analyzed.RESULTS & CONCLUSIONS:It is a natural tendency to establish PIVAS for the development of pharmacy.Several problems such as criteria for PIVAS establishment,charge standard,coverage of drug category and medication chronergy need to be further improved.

OBJECTIVE:To establish a gas chromatography(GC)method for determination of seven residual solvents in clofarabine.METHODS:The capillary column was AT-1301;the carrier gas was nitrogen gas and the detector was FID.By temperature programming was applied for the column temperature with an initial temperature of 40 ℃,which rose to 80 ℃ with an increase rate of 7 ℃?min-1,then rose to 200 ℃(kept at this temperature for 2 min)with the increase rate of 20 ℃?min-1.The injector temperature was 250 ℃ and the detector temperature was 280 ℃.The sample was injected directly for determination of residual levels of methanol,acetonitrile,dichlormethane,t-butyl alcohol,ethyl acetate,n-heptane and acetic acid in 3 batches of clofarabine.RESULTS:All the organic solvents were effectively separated and they showed good linearity within a concentration range(r=0.999 41～0.999 93)with average recovery rate ranged from 96.5% to 102.4%(RSDs of all were less than 4.0%).7 kinds of organic solvents in 3 batches of samples were all up to the standard specified in Chinese Pharmacopeia.CONCLUSION:The method is sensitive,accurate and reliable,and it is applicable for the determination of the residual solvents in clofarabine.

OBJECTIVE:To provide reference for improving safety of clinical pharmacy admixture service(PIVAS?DDS).METHODS:The main safety control measures for PIVAS?DDS in our hospital were introduced in respects of system establishment,staff,environment,safety of drug dispensing.RESULTS & CONCLUSIONS:The safety of drug dispensing is greatly inhanced through bettering working system and operational procedure,improving the cleanliness of staff,standardizing regional plan and orientation of human and material resource,which plays an important role in safety of drug use in the clinic and occupational protection,etc.

OBJECTIVE:To provide reference for the promotion of work efficiency of PIVAS.METHODS:The theory of bat-ch processing of PIVAS in our hospital was interpreted and its effect and problems were analyzed.RESULTS & CONCLUSIONS:Batch processing principal of background decision and foreground adjustment were adopted to allocate workload of different periods scientifically and improve working efficiency.Some problems existed in processing period require improvement of batch processing.

OBJECTIVE:To probe into the cost control in PIVAS of our hospital in order to provide reference for the effective cost control.METHODS:The status quo of cost control of PIVAS was analyzed to provide corresponding countermeasures.RESULTS & CONCLUSIONS:The effective cost control can be achieved through improving cost accounting,controlling cost and reducing running cost and labour cost to promote the healthy development of PIVAS.

OBJECTIVE:To probe into an inventory method of high efficiency and quality for PIVAS.METHODS:Data processing and calculation were carried out using Excel based on the information system of PIVAS.RESULTS & CONCLUSIONS:Digital inventory greatly improves the efficiency and quality of inventory.Under the condition of same workload and same number of staff,working time of digital inventory is 60% less than that of traditional inventory.And consistent rate between material and account is increased by 5%.

Objective To study the separation ability of AB-8 macroporous resin in the purification of arctinin in Fructus arctii. Methods HPLC was used to measure the content of arctinin, and the adsorption performance and the elution parameters were investigated. Results The optimal separation conditions were as follows: the concentration of Arctinin was 5.5 mg/ml with a flow rate of 2 BV/h, and 50% alcohol was used as eluant. The adsorption of Arctinin was 52.08 mg/g, and the elution ratio of arctinin was 93.8%, and the purity of arctinin reached 65.2%. Conclusion AB-8 resin can be used to refine the arctinin in the extraction of Fructus arctii.

OBJECTIVE:To systematically review the efficacy and safety of salmeterol and fluticasone propionate aerosol in the treatment of AECOPD and provide evidence-based reference for the clinical treatment. METHODS:CJFD,Wanfang database, VIP,CBM,Cochrane Library,PubMed and EMBase were retrieved to collect the randomized controlled trial(RCT)of efficacy and safety of salmeterol and fluticasone propionate aerosol in the treatment of AECOPD. After information collection and quality evalua-tion,Meta-analysis was performed by using Rev Man 5.1 software. RESULTS:There were totally 17 RCTs,including 2 872 pa-tients. Results of Meta-analysis showed FEV1[SMD=0.47,95%CI(0.41,0.53),P<0.001],FEV1/FVC [SMD=1.08,95%CI(0.76, 1.39),P<0.001],FEV1 percentage of predicted value[SMD=0.83,95%CI(0.60,1.06),P<0.001] and incidence of adverse reac-tions [RR=1.38,95%CI(1.02,1.87),P=0.03] in test group were significantly higher than control group,with significant differenc-es. CONCLUSIONS:Salmeterol and fluticasone propionate aerosol has good efficacy in the treatment of AECOPD,can better im-prove patients’lung function and the safety needs to be improved. Due to the limit of research methodology,it remains to be fur-ther verified by large-sample and high-quality RCT.
