ABSTRACT
OBJECTIVE: To observe the clinical efficacy of the combined treatment of Yishen Tongluo formula and low-dose tadalafil in diabetic erectile dysfunction. METHODS: A total of 80 patients with diabetic erectile dysfunction were randomly divided into two groups. The control group given tadalafil treatment, observation group in the control group given Yishen Tongluo Formula on the basis of treatment. The treatment period was 8 weeks. Erectile function were observed before and after treatment in the two groups patients-5 international questionnaire (IIEF - 5) score, erection quality scale (EQS) score, erectile hardness (EHS) score, TCM syndrome integral, content of serum homocysteine (HCY), endothelial function index ï¼»serum levels of prostaglandin I2 (PGI2)ï¼½ and endothelin (ET) content, a The changes of nitrogen oxide (NO), glucose and lipid metabolism indexes ï¼»triglyceride (TC), total cholesterol (TG)ï¼½ and oxidative stress related factors ï¼»total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-Px)ï¼½ were evaluated, and the clinical efficacy of the two groups was evaluated. RESULTS: In terms of overall efficacy rate, the observation group (79.4%) outperformed that of the control (48.7%, P< 0.01).After treatment, the IIEF-5 score, EQS score, EHS score, and serum levels of PGI2, NO, T-AOC and GSH-Px were higher than those before treatment in the two groups (P< 0.05). The TCM syndrome score and serum HCY, ET-1, TC and TG were lower than those before treatment (P< 0.05), and the comparison group's consequence was comparatively worse than the group under observation (P< 0.01). CONCLUSIONS: Yishen Tongluo Formula can dramatically enhance the erectile dysfunction andimprovement of glucose-lipid metabolism when adopted in together with low-dose tadalafil.
