We established animal models of osteoporosis in ovariectomized rats to detect osteoprogerin (Opg)/receptor activator of nuclear factor-κB ligand (Rankl) mRNA expression levels in the tibias and serum estradiol concentrations at different time points. Sixty Sprague-Dawley female rats were randomly selected and divided into an ovariectomized (OVX) group and sham-operated (SHAM) group. In the SHAM group, only a small amount of abdominal fat and tissues was removed from the rats.
This study aimed to explore serum adiponectin and osteoprotegerin levels in patients with coronary heart disease (CHD) and their correlation with inflammatory and ischemia factors. From September 2010 to Augest 2010, 347 CHD patients were enrolled for a retrospective analysis. Serum lipoprotein phospholipase A2 (Lp-PLA2), hypersensitive C-reactive protein (hs-CRP), ischemia modified albumin (IMA), and adiponectin and osteoprotegerin levels were detected and analyzed.
