ABSTRACT
A primary liver cancer patient complicated by hepatic cystic echinococcosis was reported. The case was admitted to the hospital due to intermittent upper abdominal discomfort for more than half a month, and an auxiliary examination revealed primary liver cancer complicated by hepatic cystic echinococcosis. Then, hepatic artery infusion and chemoembolization was performed, and no treatment was given to cystic echinococcosis lesions. Following treatment, the patient had remarkable improvements in the liver functions.
ABSTRACT
OBJECTIVE@#To determine the feasibility whether the bovine jugular venous conduit (BJVC) can be fixed with polyepoxy compound (PC).@*METHODS@#Twenty-four BJVCs were divided into 3 groups and fixed with polyepoxy compound (PC group, n = 8), glutaraldehyde (GA group, n = 8), and unfixed group (Control group, n = 8), respectively. The morphologic and mechanical properties of BJVCs in the 3 groups, including thickness, diameter, moisture content, denaturation temperature, tensile strength, elongation at break, and fixation index were measured. The rat subcutaneous model for the assessment of tissue calcification was used. The calcium content in bovine jugular vein patches and valves was determined by flame atomic absorption spectrophotometer.@*RESULTS@#There was no difference in the wall thickness, diameter, and tissue water content between PC and the control group, but significant difference was found between GA and PC groups. The mechanical properties of PC group and GA group were not significantly different, but they were better than those of the control group. GA-fixed BJVC samples showed clear calcification, while PC fixed BJVC were calcified significantly less.@*CONCLUSION@#PC is an effective and suitable choice for the treatment of BJVC since it can effectively preserve the structure and the anti-reflow function of valves in bovine jugular vein and it has better anti-calcification properties.

OBJECTIVE To evaluate the use of antibiotics in general hospitals of Ningbo. METHODS Totally 4 391 case history records in April,2004 of 12 hospitals were investigated on the use of antibiotics. RESULTS Medicines incomes accounted for 55.16% in total revenue in a hospital,and antibiotics accounted for 32.66% among medicines incomes.Antibiotics using rate was 62.11% in internal medicine departments.The percentage of antibiotics using without evidence was 23.92%,the combined antibiotics using rate was 49.89%.The average duration for antibiotics using was 10.83 days.Antibiotics using rate in surgery departments before operation was 71.00%,during operation was 20.48%,the combined antibiotics using rate during operation was 14.50%,antibiotics using rate after operation was 96.55%.Antibiotics using for treatment accounted for 62.37% and for prevention was 24.17%. CONCLUSIONS Antibiotics using rate is high in hospitals in Ningbo.Income of medicine is also an important part of total revenue in a hospital.We should pay more attention to management on clinical use of antibiotics.
