RESUMEN
Objective?To establish the way and curative effect of joint operation of CO2laser and low temperature plasma radiofrequency ablation for giant hemangioma of the larynx.?Methods?We tried to using joint operation of CO2laser and low temperature plasma radiofrequency ablation for 15 patients with giant hemangioma of the larynx.?Results?We followed up all the patients from 9 months to three years. One case recurred and treated by minimally invasive operation one more time, without recurrence after two years. The patients with mild pain and their laryngeal function were better protected. All the cases without incision of tracheal and no severe complications such as dyspnea and hemorrhage occurred.?Conclusion?The joint operation treatment of CO2laser and low temperature plasma radiofrequency ablation for giant hemangioma of the larynx holds advantages of micro-traumatic, safe and effective, and worthy to be extended on clinical.
RESUMEN
It was long believed that platelets are prematurely destroyed in the reticuloendothelial system by platelet autoantibodies in idiopathic thrombocytopenic purpura. However, humoral mechanisms cannot account for all observations made in this disorder, and it is increasingly evident that cellular mechanisms contribute to platelet destruction. In this review the tolerance of T cell, abnormality of T cell apoptosis, abnormal activation of T cells, T cell subtype and its function changes, and T cell-mediated cytotoxicity were summarized.
