Establishment and application of evaluation criteria for clinical rational drug use of atosiban based on AHP-TOPSIS method / 中国药房

OBJECTIVE To establish evaluation criteria for rational drug use of atosiban in clinic， and to provide reference for rational drug use of atosiban in clinic. METHODS Based on the drug instructions of atosiban acetate injection and related guidelines， the experts of the Evaluation Group of Rational Drug Use formulated the evaluation criteria of rational drug use， including 5 primary indexes and 8 secondary indexes. The weight coefficients of secondary indexes were calculated by analytic hierarchy process （AHP）， and the use of atosiban acetate injection in 190 pregnant women from the Third Affiliated Hospital of Guangzhou Medical University （referred to as “our hospital”） was evaluated retrospectively by technique for order preference by similarity to an ideal solution （TOPSIS）. The evaluation results were divided into three levels including reasonable， basic reasonable and unreasonable application based on the relative approach degree. RESULTS Among 190 pregnant women， 49 （25.8%） were treated with atosiban reasonably， 39 （20.5%） were treated with atosiban basic reasonably， and 102 （53.7%） were treated with atosiban unreasonably. The evaluation results obtained by AHP-TOPSIS method were consistent with the actual situation in clinic. The main problems of the unreasonably use were super indications， unreasonable usage and dosage， over the course of treatment and the lack of proper economic consideration. CONCLUSIONS The rationality evaluation criteria of atosiban’s clinical application are established by AHP-TOPSIS method； the evaluation results obtained by this method are quantifiable， scientific and reliable. The unreasonable use of atosiban is common in our hospital， and the management should be strengthened in clinical application.

Establishment of a L-02 cell model of hepatic steatosis / 南方医科大学学报

<p><b>OBJECTIVE</b>To establish an in vitro cell model for investigating hepatic steatosis in non-alcoholic fatty liver disease.</p><p><b>METHODS</b>L-02 cells cultured in 1640 containing 10% fetal bovine serum were divided into control group and model group. At 70%-80% confluency, L-02 cells in the model group were exposed to a long-chain mixture of free fatty acids (FFA, oleate and palmitate ) for 24 h, and cells in control group were treated with fresh medium. Lipid droplets in the cells were observed and total lipid content was determined with Oil Red O staining. The morphology of lipid droplets, trilyceride level, malonaldehyde content and cell apoptosis rate were evaluated to verify the cell model, and the effect of Huganqingzhi tablet on the lipid droplets was observed.</p><p><b>RESULTS</b>A large number of lipid droplets were found in the cell model, which showed markedly increased level of triglyceride without significant changes of malonadehyde content or cell apoptosis rate. Intervention with two doses of Huganqingzhi tablet significantly decreased the number of lipid droplets and trilyceride content in the cell model.</p><p><b>CONCLUSION</b>hepatic steatosis L-02 cell model can be established by long-chain mixture of free fatty acids (oleate:spalmitate=2:1) for therapeutic drug studies.</p>

Influence of prone position ventilation in conjunction with inhalation of NO on acute respiratory distress syndrome in patients / 中华急诊医学杂志

Objective To evaluate the effects of prone position ventilation (PPV) combined with inhalation of NO on oxygenation of acute respiratory distress syndrome (ARDS) patients.Methods A total of 21 patients with ARDS composed of 15 male and 6 female aged ranging from 2 to 74 years with mean age of 39 ± 17.4 years were hospitalized from September 2008 through January 2011.After application of mechanical ventilation with optimal PEEP,patients still needed the high concentration oxygen inhalation (FiO2 ≥ 60％).They were randomly (random number) divided into three groups for controlled study.Patients of group A were given NO in addition to oxygen inhalation for 4 hours,patients of group B were put in prone position ventilation with oxygen inhalation for 2 hours,then they were returned to the supine position ventilation,and patients of group C were put into prone position ventilation with inhalation of oxygen plus NO for 2 hours,and then they were returned to the supine position ventilation,but they were continued to inhaled NO.The oxygenation indexes of three groups of patients were measured before the intervention,2 hours and 4 hours after the procedure of experiment.Results The oxygenation indexes of three groups of patients were improved in terms of comparison between pre-intervention and 2 hours after intervention,but there was no statistically significant difference found in group A (P ＞ 0.05),the differences in group B and group C were statistically significant (P ＜ 0.05).Compared the oxygen index between pre-intervention and 4 hours after intervention,the differences in group A and group B were not statistically significant (P ＞0.05),but the difference in group C was statistically significant (P ＜ 0.05).Conclusions PPV could improve oxygenation in acute respiratory distress syndrome (ARDS) patients.PPV with NO inhalation could improve oxygenation in acute respiratory distress syndrome (ARDS) patients as well as effectively maintain the oxygenation after patients were returned to the supine position ventilation.Therefore prone position ventilation combined with inhalation of NO improved oxygenation and at the same time reduced the prone position time.
