Sevoflurane pretreatment inhibits the myocardial apoptosis caused by hypoxia reoxygenation through AMPK pathway: An experimental study.

Objective: To study whether sevoflurane pretreatment inhibits the myocardial apoptosis caused by hypoxia reoxygenation through AMPK pathway.

Methods: H9c2 myocardial cell lines were cultured and divided into control group (C group), hypoxia reoxygenation group (H/R group), sevoflurane pretreatment + hypoxia reoxygenation group (SP group) and sevoflurane combined with Compound C pretreatment + hypoxia reoxygenation group (ComC group), and the cell proliferation activity and apoptosis rate, myocardial enzyme levels in culture medium as well as the expression of apoptosis genes and p-AMPK in cells were determined.

Results: p-AMPK expression in cells of H/R group was significantly lower than that of C group, SP group was significantly higher than that of H/R group; cell proliferation activity value and Bcl-2 expression in cells of H/R group were significantly lower than those of C group, SP group were significantly higher than those of H/R group, ComC group were significantly lower than those of SP group; apoptosis rate, LDH, CK and AST levels as well as the Bax and Caspase-3 expression in cells of H/R group were significantly higher than those of C group, SP group were significantly lower than those of H/R group, ComC group were significantly higher than those of SP group.

[A gene chip study of "Jun Du Yan Bingzhi" on liver in a sepsis model of rat].

Objective: To study the effect of "Jun Du Yan Bingzhi" on genic change in liver of a sepsis rat model by gene chip technique, in order to study the mechanism of the action of the drug on the gene level.

Methods: Ninety rats were randomly divided into normal control group, model group and "Jun Du Yan Bingzhi" group, with 30 rats in each group. Sepsis was reproduced by cecal ligation and puncture (CLP) method.
