OBJECTIVE： To investigate the possible role of the alteration of mitochondrial transmembrane potentials(Δ Ψ m) in arsenic trioxide(As2O3)-induced apoptosis of human gastric adenocarcinoma cells(SGC7901).METHODS： Cell apoptosis was assessed through morphology， cell viability， the percentage of sub-G1 cells and phosphatidylserine(PS) externalization.the Δ Ψ m was detected on flow cytometry through double staining of Rhodamine 123 (Rh123) and propidium iodide(PI).RESULTS： The As2O3-induced apoptosis was associated closely with the disruption of the Δ Ψ m.CONCLUSION： The disruption of the Δ Ψ m is one of the mechanisms of As2O3-induced apoptosis.

OBJECTIVE:To study the curative effects of Heart nourishing Granula on viral myocarditis(VMC)model mice.METHODS:The mice were randomly divided into treatment group and control group after intraperitoneal injected(inoculation)with a diluted solution of Coxsackie virus B 3 ,the general state and the mortality of which were observed.The blood sample and cardiac tissues of the mice were taken at different time after inoculated with virus for enzyme labeled com?pound assay,virus isolation test,light microscope test and transmission electron microscope test.RESULTS:The survival rate of the treatment group was higher than that of the control group.There was significant difference(P

OBJECTIVE: To study the mechanism of intestinal absorption of protocatechualdehyde .METHODS: Using invivo rat intestinal absorption model and HPLC, the apparent small intestine absorption rate of protocatechualdehyde was mea-sured. RESULTS: Under low, medium and high concentrations of drug, the apparent small intestine absorption rates of proto-catechualdehyde were 1.1 341/h, 1.1 637/h and 1.0 847/h respectively .CONCLUSION: The protocatechualdehyde absorptionmechanism is passive diffusion.

OBJECTIVE:To investigate the dissolution of DEHP in PVC infusion set and the packaged infusion sets of the Paclitaxel injection so as to evaluate the safety of clinical infusion sets for paclitaxel.METHODS:The packaged infusion sets of Paclitaxel injection were collected from 9 Three-A grade hospitals in Chongqing.Paclitaxel injections were prepared as per actual concentration needed by the clinic and dripped through eight different infusion sets(in which 7 were packaged infusion sets) for 3 h.The peak area of the collected solution was measured and its content was determined by HPLC,and the effect of infusion time on the dissolution of DEHP was investigated as well.RESULTS:The dissolution of DEHP dripped through eight infusion sets were 1 408,9 393,6 576.5,2 412.6,8 194.4,0,8 477.2,and 8 037.4 ?g,respectively.The dissolution increased with the prolonging of infusion time.CONCLUSION:At present,the majority of packaged infusion sets of Paclitaxel injection were made form PVC materials.The safe medication of Paclitaxel can't be ensured for the dissolved DEHP can enter the blood directly,thus its hazardness should be given great attention.

lecithin. No dissolution of DEHP was noted in lecithin. In a certain kind of surfactant, the dissolution of DEHP was positively correlated with the concentration of surfactant and the infusion time and the length of the infusion tube. CONCLUSIONS: The results serve as reference for the choice of safe infusion set when surfactants is contained in the injection and the choice of surfactant in the production of injection in pharmaceutical facoties.

OBJECTIVE:To establish the method for preparation of compound fluconazole eye drops and to determine the content of fluconazole in the preparation METHODS:Detection was performed by second order derivative spectrophotometry RESULTS:Linear relationship was found in the fluconazole concentrations ranging from 80?g/ml to 400?g/ml The regression equation was D=0 0 094+0 002C,r=0 9 998 The recovery of fluconazole was 99 83%(RSD=0 69%,n=5) CO_NCLUSION:The eye drops was stable The method of determination of the content is simple,rapid and reliable

OBJECTIVE:To study the effect of concentrations of alcohol in precipitation method on polysaccharide contents in order to optimize the extractive condition of Xinmaishen oral liquid METHODS:Taking the total polysaccharides in the decoction as target and dertermining the effective components by phenol-vitriol colorimetry,the effects of 4 alcohol concentrations(50%,60%,70%,80%) on polysaccharide contents were studied RESULTS:The results showed that the polysaccharide contents sharply decreased with the increase of alcohol concentration When the alcohol concentration reached 80%,the polysaccharide content lost nearly 70% CONCLUSION:Polysaccharide content should be used as one of exam indices in screening preparation technique of this oral liquid

OBJECTIVE:To explore the necessity of developing pharmaceutical services on the retailed pharma?cy.METHODS:The current state of the pharmacy retailers in China and the necessity of developing pharmaceutical services on the retailed pharmacy were analyzed.RESULTS&CONCLUSION:Only through developing specialized pharmacy services actively can the pharmacy retailer strengthen their competitive ability in the pharmacy market.

OBJECTIVE:To ensure patients'rights of knowing the fact of medication.METHODS:The characteristics of medical care and the chief problems existed at present were analyzed.The significance and the necessity of ensuring patients'rights of knowing the fact in medication in hospital were discussed and some specific measures were proposed.RESULTS&CONCLUSION:Ensuring patients'rights of knowing the fact in medication embodies hospital's demand for"taking people as top priority",building a harmonious society,upgrading hospital's image and promoting rational drug use,which deserves great attention from the relevant hygiene authorities and hospital leaders.

OBJECTIVE: To discuss the relationship between drug price policy and the medical market order in China. METHODS: Considering Chinese medical market order, problems in drug price policy of our country were analyzed. RESULTS & CONCLUSIONS:Drug price policy of China is the one of key factor for the current medical market disorder, the formulation of which should be based on national condition and under governmental control.
