Correlation of serum miR-27a level with polycystic ovarian syndrome and its clinical characteristics

Objective: To analyze the level of serum miR-27a in patients with polycystic ovarian syndrome（PCOS） and its correlation with clinical characteristics. Methods: 96 cases of PCOS patients（PCOS group） and 60 cases of healthy women（control group） who visited People′s Hospital of Zhengzhou from Oct，2018 to Oct，2019 were collected as subjects.The levels of miR-27a in serum were detected by qRT-PCR. The follicular number（FN） and the volume of ovaries（OV） in the two groups were detected by ultrasound in the two groups. Blood samples were collected to detect the follicle stimulating hormone（FSH），luteinizing hormone（LH），estradiol，progesterone，testosterone and estrogen. Fasting blood glucose（FPG） and fasting insulin （FINS） were measured and homeostasis model assessment of insulin resistance（HOMA-IR）were calculated. The differences of all indexes between the two groups were compared. The correlation between miR-27a and clinical data in the PCOS group were analyzed by Pearson correlation analysis.The correlation between miR-27a and PCOS were analyzed by ROC curve and multivariate Logistic regression analysis. Results: The level of serum miR-27a in the PCOS group was significantly higher than that in the control group（t=6.658，P<0.05）. The level of miR-27a in the PCOS group was positively correlated with the follicular number，LH，testosterone，FPG，HOMA-IR（r=0.210，0.242，0.323，0.253，0.216，all P<0.05） and negatively correlated with estrogen（r=-0.347，P<0.05）.The area under the curve of miR-27a in diagnosing PCOS was 0.786 （95%CI: 0.716-0.848），and miR-27a level was an independent correlation factor of PCOS（OR=6.804，95% CI:2.342-19.763，P=0.000）. Conclusion: miR-27a is highly expressed in the serum of patients with PCOS and is closely related to multiple clinical features of PCOS，which might be involved in the pathogenesis and progression of PCOS.
