Predictive value of early decreased plasma ghrelin level for three-month cognitive deterioration in patients with mild traumatic brain injury.

The orexigenic hormone, ghrelin, is tightly linked to cognition impairment in neurodegenerative disorders. No previous studies have investigated the early ghrelin concentration change in patients with mild traumatic brain injury (mTBI) and it's relationship to cognitive deterioration. This study was performed to investigate the early plasma ghrelin concentrations in patients with mTBI and to explore the relationship between ghrelin and cognitive deterioration.

[Mechanism of salvianolate in preventing postoperative intestinal adhesion in rats].

Objective: To observe the effects of salvianolate on rats with postoperative intestinal adhesion and to explore the prevention mechanism.

Methods: Forty SD male rats with intestinal adhesion were randomly divided into four groups: untreated group, low-dose salvianolate-treated group (12 mg/kg), medium-dose salvianolate-treated group (24 mg/kg) and high-dose salvianolate-treated group (48 mg/kg), with another ten SD male rats as normal control. Intraperitoneal injection of glucose was administered to the rats in the normal control group and the untreated group, and intraperitoneal injection of salvianolate was administered to the rats in the low-, medium- and high-dose salvianolate-treated groups.
