Abstract:
AIM: To investigate the relationship between bone metabolism and serum leptin in type 2 diabetes mellitus (T2DM) postmenopausal female patients. METHODS: Totally 80 postmenopausal female inpatients with T2DM (according to the diagnostic criteria of WHO1999) aged 60-80 years from Yangpu District Central Hospital who gave informed consent were enrolled in the present study from January 2004 to January 2006. Exclusive criteria: Subjects who taking medications such as estrogen, glucocorticoid, or calcium or phosphorus metabolism, having a history of gastrointestinal surgery and other endocrine diseases were excluded. Each subject's age, duration, menopausal period, body mass index (BMI), fasting glucose (oxidation enzyme method), hemoglobin A1c (HbA1c) (microcolumn affinity chromatography) and leptin levels (ELISA) were measured. Ultrasound characteristics of the right heel bone were measured with ultrasound bone densitometer (French UPIS3000) to identify the speed of sound (SOS), broanband ultrasound attenuation (BUA) and stiffness (STI). STI was equal to 0.67?BUA+0.28?SOS-383. Linear correlation analysis was performed in ultrasound index, general index and leptin level. RESULTS: A total of 80 postmenopausal female inpatients with T2DM were involved in the result analysis. BUA, SOS and STI were negatively related with age (r =-0.342 to -0.298,P all
