OBJECTIVE:To investigate outpatients' cognition(including knowledge,attitude and behavior)on adverse drug reactions(ADR),and to analyze the influential factors of ADR cognition.METHODS:An on-the-spot questionnaire survey was conducted in which a total of 488 outpatients sampled from our hospital from May to December in 2007 were investigated and the data analyzed statistically.RESULTS:The correct rate was 36.6% for the questions related to cognition on ADR.70.5% of the patients investigated had a poor cognition on ADR.The factors influencing patients' cognition on ADR included educational background,ADR experience,pharmacists' guidance on medication,source of medicine knowledge,occupation,doctors' guidance on medication,community ADR lecture,and gender.CONCLUSION:The outpatients have a poor cognition on ADR.Both doctors and pharmacists should offer guidance on medication and give lecture in community to inform patients the knowledge about rational administration and ADR.

Objective To investigate the apoptosis-inducing effect,inhibiting multidrug resistanceassociated protein 1 (MRP-1) and mRNA expression of arsenic trioxide (As2O3) and buthionine sulfoximine (BSO) in multidrug-resistant cell K562/ADM.To compare the effect of As2O3 and the combined group.To determine the effect of intracellular glutathione (GSH) content on the arsenic effect.Methods The arsenic group (0.5 μmol/L,2.0 μmol/L,5.0 μmol/L) solo or combined BSO (100 μmol/L) applied in multidrugresistant cell K562/ADM.The cell proliferating activity was assessed with MTT assay.The cell apoptosis effect was detected by Annexin-V and propidium iodide (PI) staining.Intracellular GSH contents were measured using GSH Assay Kit by spectrophotometry.MRP1 expression was determined by flow cytometry.MRP1 mRNA expression were directed by semi-quantitative RT-PCR.Results With the GSH contents were degraded by the combination of clinic dose arsenic group (0.5 μmol/L,2 μmol/L) and BSO (100 μmol/L),the K562/ADM cell proliferating activity was obviously inhibited and the cell apoptosis-inducing effect was increased in 24 hours.In 72 hours,the rate of apoptosis with arsenic (0.5 μmol/L,2 μmol/L) were (8.32± 2.11) ％,(16.75±3.56) ％.After the GSH contents were degraded,the rates of apoptosis in the combination group (clinic dose arsenic group) were (82.15±9.28) ％ and (92.72±9.41) ％.The fluorescence intensity of MRP1 in 72 hours of the combination group (clinic dose arsenic group) was 8.20±0.92 and 10.40±2.33.The MRP1 attenuated effect of the combination group (clinic dose arsenic group) was obviously stronger than that of the high dose arsenic group (21.30±3.09).Conclusions The intracellular GSH contents closely correlate with the arsenic effect.The cell apoptosis-inducing effect of the combination of clinic dose arsenic and BSO on K562/ADM cell is obvious increased.The combination of clinic dose arsenic and BSO obviously inhibit MRP1 expression and MRP1 mRNA expression in K562/ADM cell.

Objective To compare the purification process of two types of ceramic hydroxyapatite(CHT I and CHT II)to remove the aggregates from two monoclonal antibodies(mAb 1 and mAb 2).Methods All the chromatography runs were performed on AKTA AVANT 150 with Tricon 10/50 column.The dynamic binding capacity( DBC) of two types of CHT was studied firstly, and then purification research was carried out selecting the suitable DBC.The column was equilibrated with 5 mmol/L sodium dihydrogen phosphate pH 6.5, and then was eluted with gradient buffers which were 10 mmol/L sodium dihydrogen phosphate pH 6.5 and 2 mol/L sodium chloride pH 6.5.Aggregate content in loading and elution pool was evaluated by size exclusion chromatography.Scale-up process was carried on 20 cm height chromatography column XK16/40.Results DBC of CHT I for mAb 1 was 40 mg/mL and mAb 2 was 45 mg/mL.After purity, monomer content of mAb 1 reached 98.6% and yield was 92.5% and monomer content of mAb 2 reached 98.8%and yield was 91.5%.DBC of CHT II for mAb1 was 16 mg/mL and mAb 2 was 20 mg/mL.After purity, monomer content of mAb 1 reached 99.8% and yield was 91.8% and monomer content of mAb 2 reached 99.9% and yield was 92.2%.Conclusion Two types of CHT both can remove aggregates effectively from monoclonal antibodies when aggregate content reaches more than 10%, and results conform to the regulations.CHT I has higher dynamic binding capacity than CHT II, and CHT II is superior to CHT I in removing aggregate efficiency.The purification process is simple and can be easily scaled up in pilot and manufacture.Therefore, it meets the requirement pilot and scale production.

Applying the effective teaching theory to the small-class teaching of pharmacology can improve the flexibility of small-class teaching mode under the guidance of the concept of effective teaching and high efficiency. The course chapters were randomly selected for traditional teaching mode or small-class teaching mode based on effective teaching theory in the same class. Practice has proved that the small-class teaching based on AO-AMFM can enhance student analysis and make careful smart objective and teaching frame work before class, and can also reach prompt activation, multi-learning, effective feedback and multi-summary, which can significantly improve students' learning enthusiasm and learning efficiency.

Objective To study the clinical characteristics and prognosis of children aged 5 or above with stage 3/4 neuroblastoma ( NB).Method Among 180 children with NB admitted from March 2007 to June 2015, 54 were aged 5 or above with stage 3 or 4.The clinical characteristics , therapeutic efficacy and prognosis of above 54 cases were analyzed.Results There were 36 boys and 18 girls with a male to female ratio of 2∶1.The most common of primary site was retroperitoneum (41/54, 75.5%), followed by mediastinum (10/54,18.5%), spine and pelvic cavity (3/545,6%).After treated by average 9 cycles of chemotherapy , 34 cases ( 63%) achieved complete remission ( CR ) , 13 ( 24.1%) achieved partial remission (PR), 5 (9.3%) presented disease progression (DP), and 2 died (3.7%).Patients were followed up for median 30 months ( 8 -99 months ) , 24 cases died and 30 survived with a overall survival (OS) rate of 55.6%.In 30 survival cases, there were 23 cases (76.7%) of event-free survival (EFS) ,and 6 cases (20.0%) of PR and 1 case (3.3%) of DP.There were significant differences in prognosis among patients with different responses to first therapy (χ2 =8.963, P =0.003 ).Among 20 children with stage 4 NB treated by autologous peripheral blood stem cell transplantation ( APBSCT ) , 13 cases died and 7 survived with an average survival time of (73.55 ±8.89)months.Among 29 cases without APBSCT, 11 cases died and 18 survived with an average survival time of(40.19 ±5.52)months.There was no significant difference in survival between APBSCT and no-APBSCT.Conclusion Children aged 5 or above with NB tend to have advanced stage , relapse and long treatment cycle , but the survival still can be improved with the appropriate treatment .
