Objective：To explore the correlation of serum chemerin and the ratio of non-high-density lipoprotein cholesterol（non-HDL-C）to high-density lipoprotein cholesterol（HDL-C） with microalbuminuria for patients with type 2 diabetes（T2DM）. Methods：According to urinary albumin to creatinine ratio（UACR），254 T2DM patients were divided into the normal albuminuria group（the NAU group，UACR<30 μg/mg，129 cases）and the microalbuminuria group（the MAU group，30 μg/mg
