Effect of Gualou Xiebai Decoction on type II cardiorenal syndrome based on endothelial/epithelial-to-mesenchymal transition and its mechanism / 中国药理学通报

ABSTRACT

Aim To investigate the protective effects of different doses Gualou Xiebai Decoction (GXD) on type II cardiorenal syndrome (type II CRS) and explore its preliminary mechanisms. Methods The type II cardiorenal syndrome rat model was replicated by li-gating the left anterior descending coronary artery. After 10 weeks of intragastric administration, the cardiac function of the rats in each group was evaluated by echocardiography; serum were collected for biochemical testing; heart and kidney tissue samples were stained with HE and Masson to observe pathological changes. The hydroxyproline content in the heart and kidney was detected. The expression levels of endothelial/epitheli-al-to-mesenchymal transition (EndMT/EMT) related proteins in heart and kidney tissues were detecterd by immunofluorescence double staining
