ObjectiveTo summarize the mechanism, risk factors, clinical manifestations, and medical treatment of hungry bone syndrome (HBS) in patients with hyperparathyroidism after parathyroidectomy, and to provide clinicians with reference for disease diagnosis and treatment.MethodThe related literatures about HBS in patients were collected and reviewed with clinical experience.ResultsHBS was a group of clinical syndromes mainly manifested as hypocalcemia after parathyroidectomy in patients with high bone turnover state before operation, with a high incidence, and the main purpose of treatment was achieved by supplementing calcium and vitamin D.ConclusionsHBS requires reasonable diagnosis and timely treatment by clinicians. Patients can achieve long-term blood calcium and phosphorus stability and bone mass growth through medical treatment.
As a kind of mechanical effector cells, chondrocytes can produce a variety of physical and chemical signals under the stimulation of multiaxial load in vivo, which affect their own growth, development and apoptosis. Therefore, simulating the mechanical environment in vivo has become a research hotspot in the culture of chondrocytes in vitro. Although a large number of reports have fully proved that different mechanical stimulation can regulate the metabolism of chondrocytes, the loading scheme has not been agreed. Starting from different mechanical forms, this review will explore the differences in the regulation of chondrocyte metabolism by different mechanical stimuli, so as to find an advantage scheme to promote the growth and proliferation of chondrocytes and to develop a more stable, effective and reliable experimental strategy.
