RESUMEN
This study analyzed the quality markers(Q-markers) of Yuquan Capsules(YQC) based on serum pharmacochemistry of Chinese medicine and detected the components and metabolites of YQC absorbed into the blood by UPLC-Q-TOF-MS and UNIFI systems. As a result, 32 components of YQC were detected, including 17 prototype components and 15 metabolized components. Among them, 12 prototype components(ginsenoside Rh_2, genistein, formononetin, puerarin, daidzein, schizandrin A, schizandrin B, schizandrin C, schizandrol A, schizandrol B, gomisin D, and ononin) and 12 metabolized components(ginsenoside Rg_1, ginsenoside Rg_2, ginsenoside Rg_3, ginsenoside Ro, 3'-methoxypuerarin, daidzin, astragaloside Ⅱ, astragaloside Ⅳ, glycyrrhizic acid, liquiritigenin, isoliquiritin, and verbascoside) showed inhibitory effects and pharmacological activities against diabetes, and these 24 blood-entering components against diabetes were identified as Q-markers of YQC.

RESUMEN
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. Conclusions Sevoflurane pretreatment can activate AMPK signaling pathway to inhibit the myocardial apoptosis caused by hypoxia reoxygenation.
