Objective: To study the effect of metformin combined with clomiphene on insulin resistance, oxidative stress response and T cell immune response in patients with polycystic ovarian syndrome (PCOS). Methods: A total of 94 patients who were diagnosed with PCOS in Jingzhou Second People’s Hospital between September 2014 and October 2016 were selected and randomly divided into the combined group who received the metformin combined with clomiphene therapy and the control group who received clomiphene therapy. The insulin resistance, oxidative stress response and T cell immune response were evaluated before treatment and 3 menstrual cycles after treatment. Results: 3 menstrual cycles after treatment, HOMA-IR level, serum F-Ins, F-CP, TOS, MDA, AOPP and IL-17 contents as well as peripheral blood RORγt mRNA expression of combined group were significantly lower than those before treatment while HOMA-β level, serum TAS, SOD, GSH-Px, VitC, VitE, IL-10 and TGF-β1 contents as well as peripheral blood Foxp3 mRNA expression were significantly higher than those before treatment; HOMA-IR and HOMA-β levels, serum F-Ins, F-CP, TOS, MDA, AOPP, IL-17, TAS, SOD, GSH-Px, VitC, VitE, IL-10 and TGF-β1 contents as well as peripheral blood Foxp3 and RORγt mRNA expression of control group were not different from those before treatment. Conclusion: Metformin combined with clomiphene can significantly improve the insulin resistance, oxidative stress response and T cell immune response in patients with PCOS.
