Objective To analyze the distributions of Chinese medical syndrome types of polycystic ovary syndrome(PCOS),and explore the differences of clinical features between different syndromes. Methods The data of 496 PCOS patients and the data of reproductive endocrine and metabolic indexes were collected and ana-lyzed retrospectively. Results The results of retrospective analysis:of the 469 patients with PCOS,163 cases were phlegm and blood stasis syndrome(34.75%),157 phlegm dampness syndrome(33.48%),90 kidney liver depression syndrome(19.19%),and 59 kidney deficiency and blood stasis syndrome(12.58%). Compared with the patients with PCOS of kidney liver depression syndrome and kidney deficiency and blood stasis syndrome,the score of acanthosis nigricans as well as the levels of BMI,WC,HC,SHBG,FAI,FPG,FINS,HOMA-IR,TG, CHOL,LDL,ApoB,and ApoB/ApoA-I ratio were significantly increased(P < 0.05),but the level of HDL and ApoA-I significantly decreased in the patients of phlegm and blood stasis syndrome and phlegm dampness syndrome (P<0.05).WHR was higher in the patients of phlegm and blood stasis syndrome than in the patients of kidney liver depression syndrome and kidney deficiency and blood stasis syndrome(P<0.05).Compared with the patients with phlegm and blood stasis syndrome,the level of ApoB and the ApoB/ApoA-I ratio were lower in the patients of phlegm dampness syndrome(P<0.05),the level of FSH and LH were higher in the patients of kidney deficiency and blood stasis syndrome(P<0.05).When compared with the patients of phlegm dampness syndrome,the level of LH was higher in the patients of kidney deficiency and blood stasis syndrome(P<0.05),but the level of T was lower in the patients of kidney liver depression syndrome(P < 0.05). Conclusions Compered with the PCOS patients with phlegm dampness syndrome,kidney liver depression syndrome,kidney deficiency and blood stasis syndrome, phlegm and blood stasis syndrome patients show more serious reproductive endocrine and metabolic disorder.
