The maximalmass was 3cm×3cm×2cm and the minimal was only 1cm×0.5cm×0.5cm.All patients underwentoperation except one autopsy.They all were followed up from 6 months to 18 years postoperatively.Symptoms of hypoglycemia were rectified without recurrence.展开更多

The effective half-lifeof,131I-lipiodol in tumor was(4.5±1.92)anys and(6.22±0.61) days. The radioactivity of lung was(13.19±3.01)% and(5.19±2.28)% espectively.These results suggest that the 131I-lipiodol biodistribution in BGPI is better than that in HAI.Clinical results showed that ABP levels dropped rapidlyin 64.3% of patients with peltive AFP.A shrinkage in tumor size was observed in 66.7% of patients.Besides transient fever,elevated bilirubin and SGPT,no any toxicity and adverse reaction wasobserved.展开更多

Of these specimens, 80% had simple epithelial hyperplasia, 16% atypical hyperplasia, 1.3% carcinoma in situ and 2.7% invasive carcinoma. Atypical hyperplasia was observed in the mucosa abjacent to carcinoma in situ which, in turn, was found in the mucosa adjacent to invasive carcinoma. This finding suggests that some of simple hyperplasia of the gallbladder evolve towards atypical hyperplasia, carcinoma in situ which finally becomes invasive carcinoma. In addition, the authors provide a morphologic criteria for grading the atypical hyperplasia of the gallbladder.展开更多
