Objective To investigate the association of leptin receptor gene Gln223Arg polymorphism with metabolism syndrome and insulin resistance. Methods The genotypes of leptin receptor in 167 patients with metabolic syndrome and 216 healthy subjects were determined by polymerase chain reaction restriction fragment length polymorphism. The biochemical indicators were detected. Results The frequency of A alleles was significantly higher in patients with metabolic syndrome than in healthy subjects. The risk of metabolic syndrome in inviduals with allele A was 3. 302 folds of that with allele G( P<0.01 ). Compared with allele G, the patients withA allele had higher body mass index,blood pressure, blood glucose, insulin level, waist circumference, and more serious dyslipidemia. The risk of insulin resistance in patients with A allele was 3. 446 folds of that with allele G (P<0.01). Conclusions Leptin receptor gene Gln223Arg polymorphism is associated with an increased risk of metabolic syndrome and insulin resistance.

Objective To investigate the therapeutic effects of alendronate combined with Caltrate D on regional bone mineral density (BMD) in elderly type 2 diabetic women with osteoporosis. Methods Thirty-four elderly type 2 diabetic women with osteoporosis aged 60-79 years (average 68. 0±4.5 years), with body mass index (BMI) of (25.0±3.7) kg/cm2 and duration of diabetes (8.9 ±4.4) years were enrolled. At the basis of a comprehensive management, the patients were treated with alendronate combined with Caltrate D for 6 months. BMD of the lumbar spine and hip, several biochemical indexes were measured before and after treatment. Results After the 6 months treatment, the BMD of different regions at lumbar spine and hip all increased. The T value and BMD were significantly higher at lumbar spines than at hip (both P＜0.01). The differences of T value and BMD of different regions were significant (P = 0.003 and 0.005,respectively). BMD percent change at lumbar spine were L4 (44.7%) ＞ L3 (31.9%) ＞ L total (27.3 % ) ＞ L1 (20.0%) ＞ L2 (14.3 % ), and the BMD percent changes were significantly higher in L3 and L4 than in other regions at lumbar spine (P=0. 038 and 0. 008, respectively). The changes of T value and BMD were significantly higher in L3, L total, L1 and L4 than in L2 (T value: P=0. 036,0. 042, 0. 006 and 0. 004, respectively; BMD: P=0. 002, 0. 002, 0. 003 and 0. 001, respectively).Conclusions On the basis of comprehensive management, the 6 months treatment with alendronate combined with Caltrate D in elderly type 2 diabetic women with osteoporosis may achieve good therapeutic effect at lumbar spines, especially at the lower lumbar spines, while less effective at hip.
