[Effects of stimulation of intact vagus nerve on systemic inflammatory response in rats].

Objective: To observe the effects of stimulation of intact vagus nerve (IVNS) on systemic inflammatory response in rats.

Methods: The model of systemic inflammatory response was reproduced by lipopolysaccharide (LPS). One hundred Sprague Dawley rats were randomly divided into A group (with intravenous injection of LPS), B group (with stimulation of efferent nerve trunk of vagus nerve after intravenous injection of lipopolysaccharide and vagotomy), C group (with stimulation of intact vagus nerve after intravenous injection of LPS), D group (with vagus nerve stimulation after injection of equivalent isotonic saline), E group (with intravenous injection of equivalent isotonic saline), with 20 rats in each group.

[The initial approach of two sides hypogastric artery ligation and isolation with laparoscope before excision of presacral tumor].

Objective: To observe the significance of excision of presacral tumor after two sides hypogastric artery ligation and tissue dissociation with laparoscope.

Methods: Twenty-one patients with sacral tumor were performed excision of presacral tumor after two sides hypogastric artery ligation and tissue dissociation with laparoscope.

Results: All sacral tumor were removed successfully, the mean volume of operative blood was 800 ml (range 500-1900 ml), and all the patients were followed up 3-25 months, averaged time 11 months.
