ABSTRACT OBJECTIVE To investigate the pharmacological components and mechanism of Qingre huoxue decoction in
improving myocardial ischemia-reperfusion injury(MIRI). METHODS Forty-two rats were randomly divided into sham operation
group (normal saline), model group (normal saline), Qingre huoxue decoction low-dose, medium-dose and high-dose groups
(4.94, 9.88, 19.79 g/kg),Qingre huoxue decoction drug-containing serum group (19.79 g/kg) and blank serum group (normal
saline), with 6 rats in each group. Each group was given corresponding drug/normal saline intragastrically, once a day, for
consecutive 2 weeks. Twelve hours after last administration, except for serum groups, MIRI model was induced in other groups
(only threading without ligation in sham operation group). After modeling, cardiac histopathology was observed and apoptosis level
was detected. UPLC-MS was used to analyze the samples in Qingre huoxue decoction drug-containing serum group and blank serum
group. The main pharmacological components were screened with the help of relevant databases. Multivariate statistical methods
were used to analyze the differential metabolites and related
