[Ultrasound, abdominal X-ray and dual-source CT in the diagnosis of colon tumor mechanical obstruction].

Objective: To study the value of ultrasound, abdominal X-ray, and dual-source CT (DSCT) in the diagnosis of colon tumor obstruction.

Methods: A retrospective analysis was conducted among 45 patients who were admitted to our department between October 2010 and August 2011 for abdominal pain. All the patients underwent ultrasound, abdominal X-ray and DSCT examinations and subsequent surgical interventions, which confirmed the diagnosis of colon tumor obstruction.

[Association of peripheral blood hypoxia-inducible factor-1α with metastasis of colorectal cancer].

Objective: To explore the relationship between hypoxia-inducible factor-1α (HIF-1α) mRNA levels in the peripheral blood and the metastasis of colorectal cancer.

Methods: HIF-1α mRNA in the peripheral blood was detected by RT-PCR in 40 patients with colorectal cancer and 20 healthy subjects.

Results: Seventeen patients with colorectal cancer showed positivity for HIF-1α mRNA, showing a significantly higher positivity rate (42.

[Application of intraoperative colon irrigation in primary resection and anastomosis of left colorectal cancer with intestinal obstruction].

Objective: To study the application of intraoperative irrigation of the colon in primary resection and anastomosis of left colorectal cancer with intestinal obstruction.

Methods: The clinical data were analyzed in 58 patients with left colon rectal cancer and intestinal obstruction undergoing intraoperative irrigation of the colon for primary anastomosis, and the results were compared with 58 patients receiving conventional primary tumor resection.

Results: The mean intraoperative blood loss or postoperative hospital stay was comparable between the two groups, but the patients undergoing colon irrigation had significantly delays in the recovery of bowel movement.

Effect of occlusive wound dressing supplemented with antiphlogistic and analgesic agents on plasma beta-endorphin in hot and humid environments: a study in pigs.

Objective: To study the changes of plasma beta-endorphin (beta-EP) in pigs with traumatic injury after occlusive wound dressing supplemented with antiphlogistic and analgesic agents in hot and humid environments (HHE).

Methods: Traumatic models were established in 10 pigs, 5 of which received antiphlogistic- and analgesic-supplemented occlusive dressings of the wounds (experiment group, EG), while the rest pigs were assigned to control group (CG) to receive routine wound management. The pigs in both groups were then exposed to artificial HHE and at different time points during the exposure, the plasma beta-EP level, respiratory frequency and heart rates were measured respectively.
