OBJECTIVETo study the distribution laws of the Chinese medicine syndrome patterns and its correlated symptoms in patients with polycystic ovarian syndrome (PCOS), and the possible correlation between Chinese medicine syndrome patterns and PCOS associated parameters, thus to provide a guidance for selecting proper indices in curative effectiveness assessment.

METHODSUsing clinical epidemiological methods and mathematical statistics, the Chinese medicine syndrome patterns were studied in 228 PCOS patients. The distribution features of Chinese medicine syndrome patterns were summarized.

RESULTSShen-deficiency blood-stasis syndrome was the most frequently seen in PCOS patients, followed by Pi-deficiency phlegm-dampness syndrome, Pi-Shen yang-deficiency syndrome, and Shen-yin deficiency syndrome. Positive correlation existed between serum levels of follicle stimulating hormone (FSH) and Pi-Shen yang-deficiency syndrome. Positive correlation existed between fasting blood sugar (FBS), waist to hip ratio (WHR), body mass index (BMI), fasting insulin (FIN), and Hirsutism score and Pi-deficiency phlegm-dampness syndrome. Positive correlation existed between serum levels of prolactin (PRL), estradiol (E2 ) and qi stagnancy and blood stasis syndrome. Positive correlation existed between serum progesterone (PRG) level, FSH, FIN, BMI, acne score and Gan stagnancy and blood heat syndrome. Positive correlation existed between luteinizing hormone (LH) and Shen-deficiency blood-stasis syndrome. Besides, LH/FSH >3 was possibly more frequently seen in Pi-deficiency phlegm-dampness syndrome and Pi-Shen yang-deficiency syndrome. Family heritability could be seen in each syndrome patterns. Among them, female heritability was more often seen in Shen-deficiency blood-stasis syndrome, while male heritability was more often seen in Shen-yin deficiency syndrome.

CONCLUSIONSShen-deficiency blood-stasis syndrome, Pi-deficiency phlegm-dampness syndrome, Pi-Shen yang-deficiency syndrome, and Shen-yin deficiency syndrome were most frequently seen in PCOS patients. The sex hormones (including 6 items), FBS, FIN, WHR and BMI, etc. were correlated with each Chinese medicine syndrome pattern to various extents, which could be taken as reference in Chinese medicine syndrome differentiation.
