[Pathogens and risk factors for ventilator-associated pneumonia in children with congenial heart disease after surgery].

Objective: To investigate the distribution and drug sensitivity of pathogens and risk factors for ventilator-associated pneumonia (VAP) in children with congenial heart disease (CAD) after surgery.

Methods: According to the occurrence of VAP, 312 children with CAD who received mechanical ventilation after surgery for 48 hours or longer between January 2012 and December 2014 were classified into VAP (n=53) and non-VAP groups (n=259). Sputum samples were collected and cultured for pathogens in children with VAP.

[Study on the effects of cool and hot ethanol extracts from qinglongyi on the biochemical function of tumor membrane in H22 mice].

Objective: To study the effects of cool and hot ethanol extracts from Qinglongyi on tumor membrane protein content, lipid fluidity, and membrane close capability in H22 mice.

Method: The membrane protein content, by, lipid fluidity and membrane close capability were measured by means of SDS-PAGE, skinitzky assay and Zamudio method respectively.

Result: The cool and hot ethanol extracts from Qinglongyi decreased the content of tumor membrane protein, the lipid fluidity and membrane close capability.
