Published 2020-01-01“…Calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), and clinical biochemical data were determined; haemoglobin A1c (HbA1c) was measured by HPLC; BMD of the femoral neck, hip, and lumbar spine (L1-4) was measured by dual-energy X-ray (DEXA); and the rs682429 and rs3781590 polymorphisms of the LRP5 gene were detected by time-of-flight mass spectrometry (TOF MS). Results. (1) The rs682429 polymorphism of the LRP5 genotype distribution was statistically significant (P<0.05) in group B compared with group A. (2) The triglycerides (TG) of women with the CT/TT genotype (mutant type) were higher than those of women with the CC genotype (wild type) (2.37±1.30 vs. 1.52±0.83, P<0.05) at the rs3781590 site of the LRP5 gene in group D. (3) Multiple linear regression analysis showed that TG (β=0.034, P<0.05) and body mass index (BMI) (β=0.013, P<0.05) were the influencing factors of BMD (L1-4) in T2DM patients. …”
