Herald of Medicine 2016;35(8):870-874
Objective To establish a method of preparing metoprolol succinate sustained-release tablet and its content determination. Methods The formulation was optimized through the orthogonal design test by using release rate of the drug as an indicator.The different batches of metoprolol succinate sustained-release tablets were determined by HPLC. Results The tablets could release drug steadily and slowly as designed,which was similar to imported tablets. The linear range of metoprolol succinate was 10-70 μg?mL-1( r=0.999 8) . Conclusion The releasing rate of metoprolol succinate sustained-release tablet prepared in optimum condition can meet the requirement. This preparation technology is simple, the assay method is rapid, sensitive and reproducible.

Objective To investigated the prevalence of obesity and metabolic syndrome (MS) and the relationship of non-alcoholic fatty liver disease (NAFLD) with MS in Hangzhou of Zhejiang province. Methods A total of 3500 subjects who were negative for hepatitis B surface antigen marker were selected to take physical examinations. Body height, body weight, blood pressure, alanine aminotransferase,fasting blood glucose,high-density lipoprotein cholesterol,and triglyeerides were recorded. B-ultrasonography of the liver and gallbladder was undertaken. Results The prevalence of MS in the NAFLD or normal control group was 25.49% and 8. 61%, respectively ( P < 0. 05 ). In multivariate logistic regression analyses, MS patients were 3. 927 times more likely to be NAFLD-related. Increased body mass index (BMI) and triglyceride were significantly associated with NAFLD among MS patients. Conclusion BMI and triglyceride level may be the main risk factors of NAFLD-related MS.

2 cm). All patients received combination chemotherapy of abdomen and vein with CAP regime and TP regime after sections.Results:Total five year survival rates were 11% in epithelial ovarian carcinoma in stage Ⅲ. The 1-.3-.5-year survival rates of the cases which had less than 4 cycles of chemotherapy were lower than those ≥6 cycles, and the recurrent rates were higher than those ≥6 cycles. The 1-.3-.5-year survival rates of TP regime were higher than those of CAP regime,and the recurrent rates were lower than those CAP regime.Conclusions:There are many relationships between prognosis and residual tumor, nucmber of chemotherapy cycles or regime after resection,which influence results of recurrent ovarian cancer after repeated tumorectomy.

In this paper, the common errors in medical devices test reports are classified and analyzed. And then the main 11 influence factors for these inspection report errors are summarized. The hierarchy model was also developed and verified by presentation data using MATLAB. The feasibility of comprehensive weights quantitative comparison has been analyzed by using the analytic hierarchy process. In the end, this paper porspects the further research direction.

Objective To investigate effect of lipid emulsion on cardiac arrest induced by bupivacain intoxication.Methods Forty SD rats were randomly devided into 2 groups.Group A applied epinephrine (n=20);Group L applied lipid emulsion combinding epinephring(n=20).The rats were administered Lupivacaine 20 mg/kg.Cardiopulmonary resuscitation(CPR) was started. Epinephrine 10 μg/kg were repeated three times followed by epinephrine 10 μg/kg every 5 minutes.Normal saline 5 ml/kg and 1 ml·kg-1·min-1 were administered in group A.20% Lipid emulsion 5 ml/kg and 0.25 ml·kg-1·min-1 were administered in group L.Heart rate,blood pressure, temperature were monitored.Blood gas analysiswere checked at 5 min,30 min after restoration of spontaneous circulation(ROSC).To record the number of successful CPR,time of ROSC and epinephrine dose.Results 11 rats(55%) and 16 rats(80%) were successful resuscitated.The success rate was higher in group L than in group A.Epinephrine dose was higher in group A than in group L.There was no difference in heart rate between the two groups.Systolic blood pressure and PaO2 was higher in group L than in group A(P<0.05).Conclusion There was better effect in lipid emulsion combined epinephrine than soly epinephrine when applied in cardiac arrest induced by bupivacaine intoxication.

ObjectiveTo investigate the effect and outcome of critically illness with acute kidney injury (AKI) treated with continuous veno-venous hemodiafiltration (CVVHDF) in children.Methods Twenty-four cases of critically illness with AKI were treated with CVVHDF in our pediatric intensive care unit from Jan 2008 to Dec 2010.The levels of creatinine (Cr),blood urea nitrogen (BUN),K +,Na + and HCO3- were observed before CVVHDF and 6,12,24,48,72 h after CVVHDF.ResultsCatheter was successfully established for CVVHDF in 24 cases of AKI.The average duration of CVVHDF was 46 h ( 16 ~142 h).The blood levels of Cr and BUN were significantly decreased at 6 h after CVVHDF [ ( 196.3 ±112.4) μmol/L,( 13.3 ± 8.5 ) mmol/L] and 12 h after CVVHDF [ ( 106.1 ± 84.2) μ mol/L,( 10.2 ± 9.7 )mmol/L] as compared to those before treatment [ (340.6 ±298.2) μmol/L,(31.6 ± 11.3) mmol/L] (P <0.05,P < 0.01 ).After 48 h of CVVHDF,the Cr,BUN returned to normal range.The imbalance of blood K +,Na +,and HCO3- improved at 6 h after CVVHDF and returned to nomal levels at 24 h.Total 28 d fatality rate was 29.2% (7/24),and all death cases were complicated with multiple organ dysfunction syndrome.ConclusionCVVHDF therapy for AKI can quickly clear Cr,BUN and excess water,correct electrolyte disorders,improve kidney function in children.
