To investigate the regularities of distribution of TCM differentiation types of polycystic ovary syndrome， and its relationship with glycometabolism and inflammatory factors IGF-I and IGFBP-1. Methods： The TCM differentiation types of 120 cases of PCOS patients was investigated， and at the same time their BMI， homeostasis model assessment insulin resistance and insulin growth factor-I (IGF-I)， insulin like growth factor binding immunoglobulin-1 (IGFBP-1) of patients were measured. The relationship between the TCM differentiation of polycystic ovary syndrome and glycometabolism， IGF-I and IGFBP-1 were explored. Results： TCM differentiation types included kidney deficiency， phlegm-dampness due to deficiency of the spleen， stagnation of liver qi， and the constituent ratio was 35%， 33%， and 32%. The difference in all the three groups was not significant， P>0.05. The levels of BMI， FINS， Homa-IR of phlegm-dampness due to deficiency of the spleen were higher than those of the other two groups， and the differences remained significant， P<0.05. The level of IGFBP-I of phlegm-dampness due to deficiency of the spleen was lower than that of the other two， and the differences remained significant， P<0.05. The level of IGF-I phlegm-dampness due to deficiency of the spleen was higher than that of the other two， and the difference was not significant， P>0.05. Conclusion： The TCM differentiation types of polycystic ovary syndrome mainly included kidney deficiency， phlegm-dampness due to deficiency of the spleen， stagnation of liver qi. The syndrome of phlegm-dampness due to spleen deficiency was relevant to insulin resistance and decline of IGFBP-1.
