Objective To explore the relationship between the circulation level of chemerin level and bone mineral density(BMD)in type 2 diabetes retinopathy patients. Methods A total of 150 patients with type 2 diabetes were selected. They were divided into two groups: retinopathy group(DR group), non- retinopathy group(NDR group). HbAlc, triglycerides(TC), total cholesterol(TG), low density lipoprotein cholesterol(LDL-C)and high-sensitivity C-reactive protein(hs-CRP)was measured by automatic biochemical detector. Bone mineral density was measured by the dual-energy X-ray absorptiometry. The BMD of lumbar vertebrae 2-4 and the left side of the femoral neck, the greater trochanter and Ward's triangle were assessed. Results ①Compared with the NDR group, the duration of diabetes in group DR was significantly longer(P<0.05); ②The levels of TC, LDL-C, HbA1c, hs-CRP and chemerin in DR group were significantly higher,③The BMD of the femoral neck, trochanter regionandward's triangle were significant reduction;④The level of chemerin was positively correlated with the duration of diabetes, BMI, HbA1C, and negatively correlated with the bone mineral density of the femoral neck, the greater trochanter, and the s' Ward triangle. Conclusion The level of chemerinin DR patients were significantly increased, and chemerin may play a role in the occurrence and development of DR, may promote the bone density decreased.
