RESUMO
BACKGROUND: Proton pump inhibitors (PPIs) remain one of the world's most frequently prescribed medications and there is a growing number of publications on correct versus incorrect use of PPIs worldwide. The objective of this observational retrospective study was to assess changes in PPI prescribing trends over the past decade and pharmacists' effect on optimizing PPI prescribing practice at a tertiary hospital in China. METHODS: We collected the prescriptions of PPIs in our hospital from January 2007 to December 2016. Then the rate of PPI prescribing, the defined daily doses (DDDs) and expenditures were calculated and plotted to show the change in utilization of and expenditure on PPIs. Reasons behind this change and effect of pharmacists' intervention were evaluated by investigating the rationality of PPI use through sample surveys of patients of pre-intervention (Jul.-Dec. 2015) and post-intervention (Jul.-Dec. 2016). RESULTS: In outpatient settings, the rate of PPI prescribing remained almost constant, utilization (from 135,808 DDDs to 722,943 DDDs) and expenditure (from 1.85 million CNY to 7.96 million CNY) increased for the past ten years, dominated by oral formulations and rabeprazole. In contrast, in inpatient settings, the rate of PPI prescribing (from 20.41 to 37.21%), utilization (from 132,329 DDDs to 827,747 DDDs) and expenditure (from 3.15 million CNY to 25.29 million CNY) increased from 2007 to 2015 and then decreased, dominated by injection formulations and omeprazole. Pharmacist interventions could significantly promote the rational use of PPIs (44.00% versus 26.67%), decrease PPI use and reduce patients' charges (P < 0.05). CONCLUSIONS: The utilization of and expenditure on PPIs grew due to the increase of patients and irrational use of PPI. Pharmacist interventions help to reduce PPI utilization and expenditure and enhance rationality for inpatients, but much work should be done to regulate injection and originator formulas, and improve the rationality in the future.

OBJECTIVE: To evaluate the impact and cost-benefit of clinical pharmacist interventions on inappropriate use of prophylactic acid suppressant in hepatobiliary surgical patients in a Chinese tertiary hospital. METHODS: A retro-prospective intervention study of patients undergoing elective operations was performed in the Department of Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University. Patients admitted from October to December 2015 and from October to December 2016, served as the pre-intervention and the post-intervention group, respectively. Clinical pharmacist interventions in the post-intervention group included real-time monitoring medical records and recommending that surgeons prescribe prophylactic acid suppressants according to the criteria established by the hospital administration. Then, the clinical outcomes of post-intervention group were compared with the pre-intervention group which lacked pharmacist interventions. In addition, cost-benefit analysis was conducted to determine the economic effects of implementing the clinical pharmacist interventions in acid suppressant prophylaxis in perioperative period. RESULTS: Clinical pharmacist interventions significantly decreased the rate of the use of no indications for prophylactic acid suppressant and of the cases of inappropriate drug selection, dose, route, replacement and prolonged duration of prophylaxis (P < 0.05 or P < 0.001), resulting in significant increase by 10.65% in the percentage of cases adhering to all the criteria (P < 0.001). Moreover, significant reductions were found in the average usage quantity (P<0.001), mean cost (P = 0.03) and mean duration (P < 0.001) of prophylaxis acid suppressant. The ratio of the mean cost savings for acid suppressants to the mean cost of pharmacist time was 13.61:1. CONCLUSION: The clinical pharmacist's real-time interventions facilitated the rational use of prophylactic acid suppressant and resulted in favorable economic outcomes in hepatobiliary surgery.

Paeonol, a potent antioxidant isolated from cortex moutan, possesses atheroprotective activity, yet the detailed mechanisms are not fully investigated. This study was conducted to explore the role of paeonol and its underlying mechanisms in RAW264.7 macrophages and apolipoprotein Edeficient (ApoE(/)) mice. Paeonol treatment significantly attenuated intracellular lipid accumulation in macrophages, which may be the result of decreased oxidized lowdensity lipoprotein (oxLDL) uptake and increased cholesterol efflux. Additionally, paeonol markedly inhibited the mRNA and protein expression of the cluster of differentiation 36 (CD36) by decreasing nuclear translocation of cJun [a subunit of activator protein1 (AP1)]. Moreover, paeonol upregulated the protein stability of ATPbinding cassette transporter A1 (ABCA1) by inhibiting calpain activity, while ABCA1 mRNA expression was not altered. Furthermore, small hairpin RNA (shRNA) targeting haem oxygenase1 (HO1) inhibited the paeonolmediated beneficial effects on the expression of cJun, CD36, ABCA1, calpain activity and lipid accumulation in macrophages. Accordingly, paeonol retarded the progress of atherosclerosis in ApoE(/) mice and modulated the expression of CD36 and ABCA1 in aortas similarly to that observed in macrophages. These results indicate that paeonol provides protective effects on foam cell formation by a novel HO1dependent mediation of cholesterol efflux and lipid accumulation in macrophages.
