Ulinastatin Improves Post-Cardiac Surgery Cognitive Dysfunction

The study comprised two primary components: a retrospective analysis of clinical big data and a conventional prospective cohort study involving patients undergoing cardiac surgery. The objectives were: 1. To assess the preventive effect of ursodeoxycholic acid on post-cardiac surgery cognitive dysfunction over an eight-year period. 2. To analyze preoperative and postoperative 24-hour plasma samples from prior studies to quantify the levels of glycocalyx and its associated regulatory factors. 3. To evaluate the clinical association between the measured parameters and patient outcomes.
