RÉSUMÉ
OBJECTIVE@#To observe the effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome (PCOS) with impaired glucose tolerance (IGT) and normal glucose tolerance (NGT).@*METHODS@#A total of 140 patients with PCOS were divided into an IGT group (70 cases, 11 dropped off) and a NGT group (70 cases, 9 cases dropped off). The patients in the two groups were treated with full-cycle acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), Tianshu (ST 25), etc. once every other day, 3 times a week, for 3 months. Before and after treatment, TCM symptom score, insulin resistance index [including fasting plasma glucose (FPG), 2-hour blood glucose (2hPG), fasting serum insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR)] and vascular endothelial related factors [including asymmetric dimethylarginine (ADMD), endothelin-1 (ET-1), malondialdehyde (MDA), nitric oxide (NO)] were compared between the two groups; in addition, the obese subgroup and non-obese subgroup of the two groups were further compared.@*RESULTS@#Compared before treatment, the TCM symptom scores, ADMD, ET-1 and MDA after treatment were decreased (@*CONCLUSION@#Acupuncture could improve vascular endothelial function in PCOS patients, IGT patients have better efficacy than NGT patients, and obese patients have better efficacy than non-obese patients.
