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 A retrospective analysis of the situation of newborn disease screening in Longwan Wenzhou from 2002 to 2009 was conducted.Methods The restdts of newborn diaease screening of 46 202 neonatus in Longwan district of Wenzhou between 2002 and 2009 were analyzed.The neonatns were screened within 72 hours after birth for congenital hypothyroidism(CH),phenylketonuria(PKU)by measuring thyroid-simulating hormone (TSH)and phenylalanine concentration on dried blood spots on filter paper cards.Neonatus weYe recalled after screened positive and the diagnosis was made by testing serum concentration.Results A total of 46 202 newborns were screened from 2002 to 2009,and 23 cases was positive and the total positive rate was 0.05%,22 cases were confirmed positive for CH.with an incidenee of 1/2 100.1 case was confirmed positive for PKU,with an incidence of 1/46 202.All patients were followed-up by experts of newborn disease screening centre of Zhejiang Province.Conclusion The results of this study confirm that newborn discease sereaning was one of the effective methods of early diagnosis of congenital CH and PKU,which could effectively prevent development low of intelligence or physique,and other organs impairment.

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.

2 cm) who were treated with endoscopic polypectomy in 2 different means,respectively.Methods The clinic data of 68 children with giant colonic polyps were review analyzed.Thirty-five cases were received endoscopic clips ligation and the other 33 cases were received endoscopic snare resection.Results All the 35 cases out of endoscopic clip ligtion group were sucessfully cured.There were only 3 cases showedl a little bleeding in this group.In the endoscopic snare resection group,there were 10 cases showed bleeding,8 cases showed polypectomy syndrome,1 case transferred into(operation).Conclusions The complication incidence in endoscopic clips ligation group is lower than that in endoscopic snare resection group.The endoscopic clipping brings about an effective and safe way to treat giant colonic polyps in children.

Hemiplegia is a common dysfunction after neurological impairment, such as acute cerebrovascular diseases, presenting as limbs functional loss especially the upper limbs, which strongly affected the activities of daily living and quality of life.
