Detection and Clinical Significance of DLC1 Gene Methylation in Serum DNA from Colorectal Cancer Patients.

Objective: Deleted in liver cancer 1 (DLC1) is a new candidate tumor suppressor gene, whose down-regulation or even silence will result from promoter hypermethylation in various human cancers including colorectal cancer (CRC). The aim of this study is toevaluate the diagnostic role of DLC1gene methylationin the serum DNA from CRC patients.

Methods: This study enrolled 85 CRC patients and 45 patients with benign colorectal diseases.

[Impact of abnormal myoelectricity at gastroduodenal anastomosis on gastric emptying in rats].

Objective: To explore the impact of abnormal myoelectricity at gastroduodenal anastomosis on gastric emptying in rats.

Methods: Rats were randomly divided into experimental group (n=16) and control group (n=16). Pylorectomy and end-to-end gastroduodenal anastomosis were performed in the experimental group and electrodes were implanted in the serosal surface adjacent to the anastomosis.

Pyloric resection and delayed gastric liquid emptying in rats.

Background: Surgical resection of the distal stomach impairs gastric emptying. Generally, pylorus and the antrum are removed in the distal gastrectomy, however, the pylorus is removed individually under specific circumstances. We focus on the relation between the pyloric resection and the gastric liquid emptying.
