ABSTRACT
OBJECTIVE： To improve the proper use of proton pump inhibitors （PPIs） and develop prescription pre-review. METHODS： Among “Hospital Self-Maintenance Rule Base” of “Rational use of drug” in our hospital， according to the application of PPIs in our hospital， the dosage of PPIs under different indications， drug combination， age range and taboo level for children were refined to promote the prescription pre-review. After refinement， the qualified rate of PPIs prescription post-evaluation among outpatient prescriptions， successful rate of pharmacist intervention during pre-prescription review and unqualified prescription rate of each item for 8 PPIs （including “interaction” “clinical diagnosis does not conform to medication” “repeated administration” “inappropriate usage”） were analyzed statistically from Jan. to Aug. 2018. The effects of fined setting were evaluated. RESULTS： From Jan. 2018 to Aug. 2018， the qualified rate of PPIs prescription post-evaluation gradually increased from 81.94％ to 95.10％； successful rate of pharmacist intervention during pre-prescription review increased from 32.75％ to 91.01％； the rate of unqualified prescriptions for 4 items decreased significantly month by month. CONCLUSIONS： The fine setting of the rules for the use of proton pump inhibitors in our hospital has effectively carried out the pre-examination of outpatient prescriptions and promoted the rational use of PPIs.

CONCLUSIONS:The optimization of ePS on tallying in our hospital improves work efficiency of pharmacists and guarantees the accuracy of tracing drug"batch/expiry".
ABSTRACT
Objective To observe the effect of mild hypothermia on myocardial β-adrenergic receptor (β-AR) signal pathway after cardiopulmonary resuscitation (CPR) in pigs with cardiac arrest (CA) and explore the mechanism of myocardial protection. Methods Healthy male Landraces were collected for reproducing the CA-CPR model (after 8-minute untreated ventricular fibrillation, CPR was implemented). The animals were divided into two groups according to random number table (n = 8). In the mild hypothermia group, the blood temperature of the animals was induced to 33 ℃ and maintained for 6 hours within 20 minutes after return of spontaneous circulation (ROSC) by using a hypothermia therapeutic apparatus. In the control group, the body temperature of the animals was maintained at (38.0±0.5)℃ with cold and warm blankets. The heart rate (HR), mean arterial pressure (MAP), the maximum rate of increase or decrease in left rentricular pressure (+dp/dt max)were measured during the course of the experiment. The cardiac output (CO) was measured by heat dilution methods before CA (baseline), and 0.5, 1, 3, 6 hours after ROSC respectively, the venous blood was collected to detect the concentration of cTnI. Left ventricular ejection fraction (LVEF) was measured with cardiac ultrasound before CA and 6 hours after ROSC. Animals were sacrificed at 6 hours after ROSC and the myocardial tissue was harvested quickly, the mRNA expression of β1-AR in myocardium was detected by reverse transcription-polymerase chain reaction (RT-PCR), the contents of adenylate cyclase (AC) and cyclic adenosine monophosphate (cAMP) were detected by enzyme linked immunosorbent assay (ELISA), the protein content of G protein-coupled receptor kinase 2 (GRK2) was detected by Western Blot. Results After successful resuscitation, the HR of both groups were significantly higher than the baseline values, CO, ±dp/dt max were significantly decreased, MAP were not significantly changed, serum cTnI levels were significantly increased. Compared with the control group, HR at 0.5, 1, 3 hours after ROSC were significantly decreased in mild hypothermia group (bpm: 142.80±12.83 vs. 176.88±15.14, 115.80±11.48 vs. 147.88±18.53, 112.60±7.40 vs. 138.50±12.02, all 1 < 0.01), CO was significantly increased at 1 hours and 3 hours after ROSC (L/min: 3.97±0.40 vs. 3.02±0.32, 4.00±0.11 vs. 3.11±0.59, both 1 < 0.01), +dp/dt max at 3 hours and 6 hours was also significantly increased after ROSC [+dp/dt max (mmHg/s): 3 402.5±612.7 vs. 2 130.0±450.6, 3 857.5±510.4 vs. 2 562.5±633.9; -dp/dt max (mmHg/s): 2 935.0±753.2 vs. 1 732.5±513.6, 3 520.0±563.6 vs. 2 510.0±554.3, all 1 < 0.05], the cTnI was significantly decreased at 3 hours and 6 hours afher ROSC (μg/L: 1.39±0.40 vs. 3.24±0.78, 1.46±0.35 vs. 3.78±0.93, both 1 < 0.01). The left at 6 hours after ROSC in both groups was decreased as compared with that before CA. The LVEF in the mild hypothermia group was higher than that in the control group (0.52±0.04 vs. 0.40±0.05, 1 < 0.05). The mRNA expression of β1-AR, and concentrations of AC and cAMP in hypothermia group were significantly higher than those in control group [β1-AR mRNA (2-ΔΔCT): 1.18±0.39 vs. 0.55±0.17, AC (ng/L):197.0±10.5 vs. 162.0±6.3, cAMP (nmol/L): 1 310.58±48.82 vs. 891.25±64.95, all 1 < 0.05], GRK2 was lower than that in the control group (GRK2/GAPDH: 0.45±0.05 vs. 0.80±0.08, 1 < 0.05). Conclusion Mild hypothermia can reduce the degree of cardiac function injury after CPR, and its mechanism may be related to the reduction of impaired myocardial β-AR signaling after CPR.
ABSTRACT
Objective To study the impact of aspirin resistance(AR)on the recurrence of artery athero-sclerotic cerebral infarction,and analyze the risk factors of AR. Methods According to TOSAT classification, newly diagnosed cerebral infarction patients with artery atherosclerotic cerebral infarction were selected into groups,and aspirin enteric-coated tables(ASP)was used to prevent platelet aggregation.One week later,the inhi-bition rate of platelet was detected by thrombelastogram(TEG),and the patients were divided into aspirin sensi-tive(AS)group and AR group,and were followed-up for at least 6 months.According to whether they were recur-rent cerebral infarction,the patients were divided into recurrent group and non-recurrent group. Then,statistical analysis was conducted.Results The incidence rate of AR in recurrent group was significantly higher than that in non-recurrence group(P < 0.05);the recurrence rate of cerebral infarction in AR group was significantly higher than that in AS group(P<0.05).When compare the clinical indexes between the recurrence group and non-recur-rence group,age,diabetes,TC,Hcy,Apo-a in the two groups were different(P<0.05).In recurrent group,the distribution of diabetes,LDL-C and Hs-CRP were different between AR and AS group(P<0.05).Age,gender, hypertension,diabetes,Hs-CRP and TC were risk factors for AR.Conclusions AR plays an important role in the relapse of artery atherosclerotic cerebral infarction and it is more likely to occur especially accompanied by adverse factors such as underlying diseases. TEG can be used to detect AR rapidly and conveniently,which has practical significance in preventing recurrent cerebral infarction.
