Effect of “Yingwei Fang” on Lower Extremity Vascular Lesions in Patients with Different Syndromic Type 2 Diabetes

Objective: To investigate the changes of ankle-brachial index (ABI) and peak velocity of dorsal foot artery in patients with type 2 diabetes mellitus with lower extremity vascular disease treated with Yingweifang. Methods: 36 cases of type 2 diabetes mellitus with lower extremity vascular disease were observed, including 13 cases of Yin deficiency and hot, 9 cases of qi and Yin deficiency and 14 cases of Yin and Yang deficiency. Oral “Yingwei Fang” capsule, 5 capsules per time, 3 times a day, combined with the dialectical TCM dialectical theory of treatment, conventional treatment such as hypoglycemia. Changes in the ankle-brachial index (ABI) and peak flow rate of dorsal foot artery were measured after 150 days of treatment compared with before treatment. RESULTS: After treatment, ABI and peak flow rate of dorsal foot artery in diabetic lower extremity vascular disease patients were changed in different degrees (P < 0.05, P<0.01), and ABI was improved more obviously (P <0.01). Qi and Yin deficiency and Yin and Yang deficiency were also improved (P<0.05). The comparison of desiccation and heat between Qi and Yin deficiency and Yin deficiency after treatment (P<0.05); CONCLUSIONS: Yingwei Fang can significantly improve the ankle-brachial index (ABI) and peak velocity of dorsal foot artery in patients with lower extremity vascular disease of type 2 diabetes mellitus.
