Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

study group

1000 Male and female patients undergoing non-cardiac surgery at the Affiliated Hospital of Xuzhou Medical University \[Jiangsu China\]. We do the neuropsychological tests, Mini-Mental score examination (MMSE) and olfaction test 1 day before (baseline) and 1 week,3 months,1 year and 3 years after surgery without safety issue.We also measure their preoperative leukocyte telomere length.

Neuropsychology test

Intervention Type DIAGNOSTIC_TEST
