【摘要】Objective To investigate whether the polymorphism of osteoprotegerin(OPG)gene is associated with the change of BMD(bone mineral density)after alendronate therapy in postmenopausal women with osteoporosis and determine the correlation between genotypes and therapeutic effect.Methods Eighty postmenopausal osteoporotic patients were recruited with an average age of(64.2±7.7)years old. Every patient took oral alendronate(Fosamax)70 mg weekly and Caltrate 600 mg daily for 12 months.At pre-and post-treatment.BMD was measured at lumbar spine 2-4 and hip sites.PCR-RFLP was performed for three polymorphisms at the promoter site of OPG gene(A163G,T245G and T950C).Results
