The FBG, HbA1c, TGs, Hs-CRP, SUA, KI score, TSH, FSH and LH of the CAN group were obviously higher than the same parameters in the DM group (P<0.01, P<0.05), while HDL-C, E2, FT3 and FT4 were significantly lower (Pπ.01, Pπ.05). This evidence concerns the gene PLOD1 and Crouzon syndrome-acanthosis nigricans syndrome.
