Effect of “Ying Wei Fang” on Vascular Endothelial Function in Patients with Different Syndromes of Type 2 Diabetes Mellitus

Objective: To investigate the effects of “Yingwei Fang” on nitric oxide synthase (eNOS), endothelin-converting enzyme (ECE) and homocysteine (Hey) in patients with type 2 diabetes mellitus. Methods: 39 cases of type 2 diabetes mellitus with different syndromes were observed, including 14 cases of Yin deficiency heat, 10 cases of Qi and Yin deficiency and 15 cases of Yin and Yang deficiency. All patients took “Yingwei Fang” capsules orally, 5 capsules per time, 3 times a day. At the same time, they were combined with conventional treatment such as dialectical TCM dialectical theory of treatment and hypoglycemia. The changes of eNOS, ECE and Hcy were measured after 150 days of treatment and compared with those before treatment. RESULTs: After treatment, there were changes in
$e$
NOS, ECE and Hcy in patients with Yin deficiency, Qi and Yin deficiency and Yin and Yang deficiency, among which eNOS, ECE and Hcy were significantly improved (P<0.05). ECE and Hcy were significantly improved in both Qi and Yin deficiency (P<0.01). Conclusion: “Yingwei Fang” can significantly improve vascular endothelial function in patients with type 2 diabetes.
