OBJECTIVE:To promote standardized management of PIVAS.METHODS:The experience of the management of PIVAS in our hospital was summarized to explore the suitable management model of PIVAS.RESULTS & CONCLUSIONS:The efficiency and quality of PIVAS management is improved and the management of PIVAS is standardized by establishing operational procedure,management criteria,management group and evaluation standard.

OBJECTIVE:To study the anti-inflammatory effect of ethanol extract of Polygonum multiflorum METHODS:To observe the oedema severity and vaso-permeability in inflamed animal and the response of animal to pain induced by acetate acid after the ethanol extract of Polygonum multiflorum had been intragastrically given for 3 days RESULTS:The oedema severity and vaso-permeability were obviously decreased by the ethanol extract of Polygonum multiflorum and this effect could last 4 hours At the large dose,analgesic effect was observed CONCLUSION:The ethanol extract of Polygonum multiflorum exhibits intensive anti-inflammation effect and the mechanism may be related to its immuno-depression effect

OBJECTIVE:To establish an HPLC method for determination of ganciclovir in serum of dogs and to study pharmacokinetics and relative bioavailability of Ganciclovir dispersible tablets.METHODS:The determination was performed on Dikma DiamonsilTM C18 column.The mobile phase consisted of 0.015 mol?mL-1 monobasic potassium phosphate buffer solution (pH 2.50,containing 0.25% acetonitrile) with flow rate of 1.75 mL?min-1 at detection wavelength of 254 nm.The column temperature was set at 40 ℃.In a randomized cross-over study,a single dose of dispersible tablets and the capsule were given to 6 dogs.An HPLC method was used to determine plasma concentration of ganciclovir in dogs and the pharmacokinetic data were treated by DASver1.0 software.RESULTS:The linear range of ganciclovir were 0.050 25～100.5 ?g?mL-1;the methodological recovery was larger than 90% (RSD

AIM To investigate the protective effects of three flavonoids quercetin,rutoside and flavone on the intestinal mucosal injury induced by burn in mice. METHOD The change of injury index of small intestine was assayed and the content of protein and DNA were measured. DTNB method were adopted to measure the GSH content in the intestinal mucosa. The level of DNA damaged were determined by measuring the fluorescence. RESULTS The condition of injury of intestinal mucosa were improved in varying degrees after these favonoids were given introgastrically for 3 days. The injury index of intestinal mucosa decreased and the content of protein,DNA and GSH increased. The degrees of DNA damage were reduced also.Quercetin was the most effective one among these three flavonoids. CONCLUSION The flavonoids of quercetin, rutoside and flavone have obvious protective effects on burn induced intestinal mucosal injury, and the mechanism may be related to its antioxydation function.

Objective To observe the effects of quercetin on PGE 2 release and cyclooxygenase activity in IEC 6 cells stimulated by the serum of burned rats. Methods The PGE 2 levels were measured by radioimmunoassay and the changes of cyclooxygenase activity were determined by substrate fluorescence analysis. Results Stimulated by the serum of burned rats, the PGE 2 level increased first and then obviously decreased. Quercetin at 0.1 and 1.0 ?mol/L enhanced the PGE 2 level after the stimulation of IEC 6 cells for 24 h. There was no obvious change in total cyclooxygenase activity, but the activity ratio of COX 1 to COX 2 significantly decreased. Conclusion Quercetin might influence the release of cyclooxygenase metabolite PGE 2 through the regulation of COXs activity in IEC 6 cells.

Objective To prepare microspheres of dextro ketoprofen ? cyclodextrin (S KP ? CD) for prolonging the drug releasing time in vitro . Methods Microspheres containing S KP ? CD were prepared by complex coacervation method with gelatin and acacia. Trap efficiency, drug loading, and drug content were determined. The dissolubility of S KP in the intestinal liquid was compared with that in the gastric liquid. Results In comparison with S KP, microspheres of S KP ? CD possessed slow releasing property. Conclusion Drug microspheres prepared by this simple, easy, and accurate method are of slow releasing property.

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 improve the management of dispensing room in PIVAS in order to provide reference for standardized disposition of drugs.METHODS:The condition of the management of dispensing room of PIVAS in our hospital was introduced in respect of staff management,material management,disposition management,environment and equipment management.RESULTS & CONCLUSIONS:The quality and efficiency of disposition of intravenous drugs are improved through improving management of above four aspects to guarantee the medication safety of patients.

OBJECTIVE:To strengthen the clinical rational use of drug and to ensure safety of drug use.METHODS:The irrational medication orders of PIVAS in our hospital from Mar.to Aug.in 2009 were analyzed statistically.RESULTS:Of total 859 339 medication orders,771 irrational medication orders accounted for 0.94‰,including excessive dosage,irrational compatibility and improper solvent selection,etc.CONCLUSIONS:Pharmacists can correct irrational medication order to improve rational use of drug by PIVAS.Moreover,PIVAS plays an important role in training clinical pharmacists.
