Abstract:Objective To explore the relationship between serum cystatin C, uric acid and bone mineral density in patients with type 2 diabetes mellitus, and to analyze the related factors of diabetic osteoporosis. Methods From January 2018 to May 2019, 228 patients with type 2 diabetes treated in the Department of Endocrinology, the Second Affiliated Hospital of Zhengzhou University were selected. According to the World Health Organization (WHO) diagnosis standard of osteoporosis, they were divided into normal bone mass group (43 cases), low bone mass group (87 cases), osteoporosis group(77 cases)and severe osteoporosis group(21 cases).The general data of patients were collected.The correlation between biochemical parameters and bone mineral density was analyzed and the possible mechanism was discussed. Results There were significant differences in sex, age, course of disease, diastolic pressure, glycosylated hemoglobin, total cholesterol,triacylglycerol,high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, blood phosphorus, alkaline phosphatase, blood creatinine, blood uric acid, serum cystatin C, 25 hydroxyvitamin D and estimated glomerular filtration rate, lumbar spine 1-4 (L1~4) bone mineral density, bilateral femoral neck bone mineral density among the four groups (P<0.05). There were no significant differences in body mass index、systolic blood pressure、fasting plasma glucose、2-hour postprandial glucose C-peptide、serum Ca、blood urea nitrogen among the four groups (P>0.05). Correlation analysis showed that bone mineral density of L1~4 positively correlated with serum uric acid,alkaline phosphatase (r=0.334, 0.443; P<0.05), negatively correlated with serum P, glycosylated hemoglobin, cystatin C(r=-0.224, -0.371, -0.357; P<0.05); bone mineral density of the left femoral neck positively correlated with serum uric acid, alkaline phosphatase (r=0.242, 0.607; P<0.05), negatively correlated with serum P, glycosylated hemoglobin, cystatin C (r=-0.156, -0.351, -0.442; P<0.05);bone mineral density of the right femoral neck positively correlated with serum uric acid、alkaline phosphatase (r=0.229, r=0.609; P <0.05), negatively correlated with serum P, glycated hemoglobin, cystatin C (r=-0.134, -0.276, -0.414; P<0.05). Multiple linear regression analysis showed that glycosylated hemoglobin, alkaline phosphatase, serum cystatin C and uric acid were the related factors affecting bone mineral density in patients with type 2 diabetes mellitus (P<0.05). Conclusion High levels of serum cystatin C may be risk factors for osteoporosis in patients with type 2 diabetes, and high blood levels of uric acid may be the protection factors.
