摘要

In order to explore the mechanism of Extract Gingko biloba (EGb761) inhibiting vascular calcification in rats with chronic kidney disease (CKD) through ROS-NF-κB signaling pathway, adult male healthy SD (Sprague Dawley) rats were selected as the research objects. Animal models were constructed and randomly divided into control group, high phosphorus-induced residual renal vascular calcification model group (HPIAC group), and EGb761 intervention calcification group. Samples were collected from each group of rats, and the renal function, aortic calcification, and the expression of related proteins were detected by Western blot. The results showed that the contents of urea nitrogen, creatinine, and phosphorus in calcification model group increased significantly, with significant statistical difference (P?
