    Notes: Abstract Functional inactivation of the tsg101 gene in mouse fibroblasts results in cell transformation and the ability to form metastatic tumors in nude mice. The human tsg101 gene was mapped to chromosome 11q15.1-2 and found to mutate in some cancer patients. To test the expression pattern of the tsg101 gene in Chinese breast cancer patients, we analyzed the mRNA by RT-PCR in 51 breast cancer patients. The full-length tsg101 and 7 truncated transcripts were detected in both normal and matched tumor tissues. A short transcript with a deletion of nucleotides 154–1054 is frequently presented in late-stage breast cancers. TSG101 protein expression was also detected by Western blot analysis in 30 breast cancer patients. A predicted full-length 46 kDa and three proteins with smaller molecular weight were detected. The full-length 46 kDa protein was less expressed in tumor specimens. Immunohistochemical stains from 10 patients of each stage 0–4 revealed that TSG101 protein was predominantly present in the cytoplasm. Cell nuclei were occasionally immunopositive and the chromosomes were deeply stained during cell division. The intracellular location and the expression of TSG101 protein were both not stage-dependent in primary breast cancers. In addition, normal mammary glands were more homogenously immunopositive than invasive ductal carcinoma. These results support the notion that the aberrant expression of TSG101 in breast cancer is associated with altered cell growth.

    Notes: Abstract Bile duct injury is a serious complication of laparoscopic cholecystectomy, with 50% of bile duct injuries showing a delayed presentation. We experienced four patients (one male and three female) with bile duct injuries after laparoscopic cholecystectomy performed and referred by a local practitioner. The patients' ages ranged from 34 to 63 years. Symptoms included abdominal pain, anorexia, jaundice, ascites, ileus, fever, and tarry stool. Ductal injuries were a result of electrocautery burn in two patients and biliary strictures were due to malapplication of endoclips in the remaining two. The observed bile duct injuries, confirmed by ultrasonography, computed tomography (CT) scanning, and cholangiographic studies, were successfully treated by choledochotomy with a silastic T-tube stent. To avoid bile duct injuries, laparoscopic cholecystectomy should be performed by a well trained and experienced hepatobiliary surgeon, who should ensure accurate identification of the anatomical structures of Calot's triangle, careful dissection and management of intraoperative bleeding, and a lower threshold for conversion to open surgery.
