Aims of the present study is to explore the relationship between DPN parameters and FMD, providing a new approach for the prevention of CVD.Patients and Methods: A total of 272 patients with T2DM from the Department of Endocrinology of The First Hospital of Lanzhou University according to the grading criteria were selected. FMD was measured by a new vascular ultrasound system and patients were divided into FMD> 7%, 4%≤FMD≤ 7%, and FMD 7% (2%). Among the TCSS indicators of all subjects, the proportion of temperature disturbance was the most (73%), and joint position disturbance was the least (0). TCSS scores were negatively correlated with FMD (r=− 0.756, p< 0.001). More interesting, in FMD< 4% group, CV and Amp were positively correlated with FMD, while DML was negatively correlated (p< 0.05). Linear regression analysis model showed that different systolic blood pressure (SBP), triglyceride (TG), TCSS and CV had statistically different effects on FMD.Conclusion: High TCSS score and decreased CV of common peroneal and tibial nerves are risk factors of FMD injury, which provide potential value for timely prevention and treatment of cardiovascular diseases.Keywords: type 2 diabetes, diabetic peripheral neuropathy, vascular endothelial function, cardiovascular disease, Toronto clinical scoring system
