RESUMEN
Osteoporosis is one of the common complications of type 2 diabetes mellitus (T2DM). Recent studies have shown that glucagon-like peptide-1 receptor agonists (GLP-1RAs) can promote bone formation and inhibit bone resorption, suggesting that this hypoglycemic drugs may benefit T2DM patients with osteoporosis and high fracture risk, but its underlying mechanism is not fully understood, and different GLP-1RAs exhibit different skeletal effects and molecular mechanisms. In this paper, the effects of several GLP-1RAs on bone metabolism are reviewed.
RESUMEN
@#Objective To investigate the protective effects of Naoxintong capsule on cerebral ischemia-reperfusion injury in rats.Methods 45 SD rats were randomly divided into 5 groups: sham operation group (n=5), ischemia-reperfusion group (n=10), small dose of Naoxintong capsule group (n=10), large dose of Naoxintong capsule group (n=10), CoQ-10 group (n=10). The the cerebral ischemia-reperfusion model was established by occluding bilateral carotid arteries of animal. The moisture content and activity of ATPase in brain tissue of model rat were observed respectively at ischemia 30 min plus reperfusion 30 min and ischemia 30 min plus reperfusion 60 min.Results The activities of Na+-K+-ATPase, Ca2+-ATPase and Mg2+-ATPase decreased (P<0.01), contents of water in brain tissues increased (P<0.01) in the ischemia-reperfusion group, compared with the sham operation group. The activities of Na+-K+-ATPase, Ca2+-ATPase and Mg2+-ATPase increased (P<0.01), contents of water in brain tissues decreased (P<0.01) in the Naoxintong capsule group, compared with the ischemia-reperfusion group.Conclusion Naoxintong capsule can protect the brain tissue from ischemia-reperfusion injury.
