ABSTRACT
ObjectiveTo observe the therapeutic effect of Wang's Yijing decoction combined with conventional therapy on the treatment of polycystic ovary syndrome （PCOS） with kidney deficiency and phlegm-dampness syndrome and its regulating effect on the intestine-brain axis. MethodThe 132 patients from the gynecological clinic of Shanxi Bethune Hospital were randomly assigned into a control group and an observation group， with 66 patients in each group. The patients in the control group were treated with drospirenone and ethinylestradiol tablets and metformin tablets， and those in the observation group were administrated with Wang's Yijing decoction on the basis of the therapy in the control group. The treatment in both groups lasted for 3 menstrual cycles. The changes in menstrual blood volume， color， and texture， as well as that in the menstrual cycle before and after treatment were scored. Further， the Rosenfield， hirsutism， and kidney deficiency and phlegm-dampness syndrome were scored before and after treatment. Pelvic ultrasound was performed before and after treatment to compare the bilateral ovarian volume. The levels of anti-mullerian hormone （AMH）， estradiol （E2）， luteinizing hormone （LH）， follicle-stimulating hormone （FSH）， testosterone （T）， dihydrotestosterone （DHT）， and sex hormone-binding globulin （SHBG） were measured before and after treatment， and the free androgen index （FAI） was calculated. After the fasting insulin and fasting blood glucose were examined before and after treatment， the homeostatic model assessment of insulin resistance （HOMA-IR） was calculated. The levels of ghrelin， glucagon-like peptide-1 （GLP-1）， peptide tyrosine-tyrosine （PYY） in serum and short-chain fatty acids （SCFAs） in fresh stool were measured before and after treatment. ResultThe treatments in both groups lowered the scores of irregular menstruation， Rosenfield， hirsutism， and kidney deficiency and phlegm-dampness syndrome （P<0.01）， and the scores in the observation group were lower than those in the control group （P<0.01）. After treatment， the T， DHT， FAI， AMH， E2， LH， and FSH levels lowered （P<0.01）， while the SHBG level elevated （P<0.01）. In addition， the AMH， E2， LH， T， DHT， and FAI in the observation group were lower than those in control group， while the SHBG level presented an opposite trend （P<0.01）. After treatment， the bilateral ovarian volume and HOMA-IR of the two groups decreased （P<0.01）， and were lower in the observation group than in the control group （P<0.05， P<0.01）. The treatments in both groups elevated the levels of ghrelin， GLP-1， PYY， and SCFAs （P<0.01）， which were higher in the observation group than in the control group （P<0.01）. After treatment， the recovery rate in the observation group was 65.57% （40/61）， which was higher than 44.83% （26/58） in the control group （χ2=5.180， P<0.05）. ConclusionWang's Yijing decoction combined with conventional western medicine treatment can regulate the intestine-brain axis， endocrine and metabolic disorders， and sex hormones， adjust the menstrual cycle， and alleviate clinical symptoms， demonstrating good clinical effect for the PCOS patients with kidney deficiency and phlegm dampness syndrome.
