[Distribution and antibiotics resistance related to nosocomial pathogenic bacteria infection in patients after cardiac surgery].

Objective: To investigate the clinical distribution and antibiotics resistance of nosocomial infection caused pathogenic bacteria in patients after cardiac surgery.

Methods: Clinical data from 612 patients after cardiac surgery under microbiologically documented nosocomial infection was retrospectively analyzed from January 2007 to December 2012. Identification on related bacterial was performed in an automatic ATB Expression system while antimicrobial susceptibility was tested by Kirby-Bauer method.

Myocardial autophagy variation during acute myocardial infarction in rats: the effects of carvedilol.

Background: The loss of cardiac myocytes is one of the mechanisms involved in acute myocardial infarction (AMI)-related heart failure. Autophagy is a common biological process in eukaryote cells. The relationship between cardiac myocyte loss and autophagy after AMI is still unclear.
