RESUMO
OBJECTIVE:To explore the construction effect of rational drug use monitoring system on the improvement of clini-cal drug use in the hospital. METHODS:The data about the construction of rational drug use monitoring system were collected from our hospital,including pharmacist workstation prescription check(check before prescription/medical order charging to realize warning in advance),clinical pharmacy management system prescription comment(realize prescription/medical order comment after-wards)and adverse drug reaction/adverse drug event(ADR)reporting information platform(realize online ADR reporting)during 2014-2015. The data was analyzed to evaluate the effectiveness of system construction. RESULTS & CONCLUSIONS:There were a total of 3 417 329 prescriptions audited by the pharmacist workstation within 2 years through improving system functions,includ-ing 7 315 prescriptions were returned to doctors to be modified,the percentage of which declined from 0.39% to 0.08%. The pass rate of prescription comment pre-judgment increased from 81.2% to 90.4% in 2015 by clinical pharmacy management system. The valid case number of ADR monitoring and reporting increased from 186 cases to 267 cases,involving all department of our hospi-tal. The construction of rational drug use monitoring system in our hospital can improve the standardization of prescription/medical orders,the level of rational drug use and the case number of ADR,which has achieved the expected results.
RESUMO
To examine the histological changes of diabetic rats' skin and the effects on the percutaneous absorption of hydrocortisone (HC, a glucocorticoid), male Wistar rats were randomly divided into five groups: control group, diabetes one-week group (W1), two-week group (W2), three-week group (W3), and four-week group (W4), while each group contained 6 rats. Diabetes mellitus (DM) rat model was prepared with the method of streptozocin (STZ, 40 mg x kg(-1)) intraperitoneal injection. Abdominal skin was cut to carry out an in-vitro penetration experiment on an improved Franz diffusion cells, and phosphate buffer (PBS, pH 7.4) was used as receptor solution. The solution was analyzed with HPLC, and then the penetrating rate can be calculated. Meanwhile, rats' abdominal skins of different DM periods were HE stained and made into tissue slices to find if any histological changes occurred. The penetrating rate of control, W1, W2, W3, and W4 groups were 2.39 +/- 1.25, 3.22 +/- 1.72, 3.02 +/- 1.89, 3.63 +/- 2.02 and 5.00 +/- 3.36 microg x h(-1) x cm(-2), respectively. There was significant difference between the control and the W4 group (P 0.05). The tissue slices showed that compared to the normal rats' skin, little change was observed in one-week DM rats' skin, but the skin of one-month DM rats' skin was observed thinner, and it became much thinner than that of rats with two-month diabetes, especially the epidermis. After making a rat into diabetic, the rats' skin goes through a pathological change, and this change is closely interrelated with the increase of the permeation of HC. Therefore, it is necessary to adjust the dose while some drug was applied on the skin in case of diabetes mellitus.
