[Compatibility mechanism of Qishen Yiqi Dripping Pills for treatment of myocardial ischemia based on UPLC-Q-Exactive Orbitrap-MS and network pharmacology].

Clinical efficacy and mechanism of Qishen Yiqi Dripping Pills(QSYQ) have been well researched, but the compatibility mechanism underlying its therapeutic effect still requires further analysis. This study aims to explore the compatibility mechanism of QSYQ in treating myocardial ischemia. UPLC-Q-Exactive Orbitrap-MS technique was used to obtain the absorbed blood components of QSYQ.

Establishment and comparison of Actinobacillus pleuropneumoniae experimental infection model in mice and piglets.

Actinobacillus pleuropneumoniae (APP) causes porcine pleuropneumonia, a disease responsible for substantial losses in the worldwide pig industry. In this study, outbred Kunming (KM) and Institute of Cancer Research (ICR) mice were evaluated as alternative mice models for APP research. After intranasal infection of serotype 5 reference strain L20, there was less lung damage and a lower clinical sign score in ICR compared to KM mice.
