ABSTRACT
Objective To investigate the CT imaging findings and diagnostic methods of extragonadal seminoma.Methods The CT imaging findings and the causes of misdiagnosis in 6 cases of extragonadal seminoma before and after CT-guided biopsy were analyzed retrospectively in this study.Results One case of seminoma was found in the right supraclavicular region,mediastinuml,retroperitoneal cavity and retroperitoneal-retroperitoneal cavity,respectively.Two cases located in the pelvic-abdominal cavity.Lesions were substantially isodensity soft tissue masseswith creeping growth,clear boundary,mild to moderate enhancement and peripheral blood vessels embedded in the tumor.All the cases performed CT-guided biopsy.The diagnoses before and after puncture were inconsistent,so the misdiagnosis rate was 100%. Conclusion Extragonadal seminoma occurs randomly in the different location and imaging features are lack of specificity,therefore, it is difficult to diagnose qualitatively.CT-guided biopsy is the most effective clinical method of the diagnosis of extragonadal seminoma.
ABSTRACT
Objective To explore the efficacy of somatostatin and pantoprazole sodium in treatment of severe acute pancreatitis. Methods 124 cases with severe acute pancreatitis admitted in the People's Hospital of Zhoushan City from Jan 2011 to Jan 2014 were randomly divided into control group and combination group,each had 62 cases. Patients in control group were treated with pantoprazole sodium,while in combination group were treated with somatostatin and semi Pantoprazole sodium. Results The total effective rate in combination group was 95.16%,higher than 64.52% in control group. the difference was significant(P<0.05 ). The recovery time and the incidence of complication in combination group was significantly lower than control group (P <0.05 ). Conclusion Somatostatin and pantoprazole sodium can effectively improve the treatment efficiency of SAP patients,shorten recovery time,and reduce the incidence of complication.
ABSTRACT
OBJECTIVE: To prepare the disinfectant for venepuncture in children and to establish the quality control for this preparation. METHODS: Nicotinic acid and racanisodamine were taken as the chief components for the preparation of this disinfectant, 75% alcohol as the solvent. Nicotinic acid were determined by ultraviolet and visible spectrophotometry(UV-Vis); racanisodamine were determined by nonaqueous titrations. RESULTS: The average recoveries of racanisodamine and nicotinic acid were 99.96%(RSD=0.04%) and 100.04%(RSD=0.16%) respectively, which all were in the range of 98.87%～100.8%. CONCLUSION: The disinfectant produced with the established method is simple in preparation, accurate in content determination, stable and reliable in quality.
ABSTRACT
We have studied mainly the distribution of this ~3H-labelled schistosomicidal drug in the livers and brains of the albino mice. In livers the ~3H-labelled substances were localized in greater quantity in the liver cell trabecula than in the sinusoids, and were taken up by the Kupffer's cells too. But the most prominent condense localization of the ~3H-labelled substances were in the interlobular bile ducts indicating that the original agent and its metabolites were excreted through the bile ducts system. The nuclei of the liver cells contained a certain amount lof the ~3H-labelled substances, about 7 silver grains in each nucleus with a diameter of about 10.7? seen in 2? thick freezing sections. One of the metabolites of this schistosomicidal drug being a mutagenic agent, the appearance of ~3H-labelled substances in the cell nuclei attracts our great attentions. As for the genesis mechanism of jaundice after administration of this schistosomicidal drug, our opinion is that it might be chiefly the result of drug sensitizied allergy reaction in accordance with a lot of works in the clinics, immunological test, pharmacological principles and our present studies. In the brains, the ~3H-labelled substances distributed much more in the white substances than in the gray substances, with the exception of the substantia nigra which had the same density of number of silver grains as the white substances. With these findingsthe clinical symptoms of the nervous system and their recovery were reviewed.
ABSTRACT
Objective To analyze risk cause on adverse apparatus events of medical institution for causing the attention of medical institutions and reducing or exempting the occurrences. Methods Through the analysis risk cause on adverse apparatus events of medical institutions, the major factors of causing the medical institutions adverse apparatus events and the ways of solving the problems were found. Results The ways and countermeasure of solving medical institutions adverse apparatus events are brought forward. Conclusion It is preventable in adverse apparatus events of medical institutions.
