ABSTRACT
Objective To investigate the changes of serum TNF-α,IL-1β,IL-10,IL-13,lung ultrastructure and respiratory function in the early stage of pulmonary contusion. Method 16 white rabbits were randomly assigned to lung contusion group and control group. Pulmonary contusion was established. Serum TNF-α,IL-1β, IL-10 and IL-13 level at 1 ,2 ,3 and 4 h after contusion were tested. Respiratory function data was obtained and ultrastructure was observed. Results In the early phase after pulmonary contusion ,the expression of IL-1β and TNF-αincreased while IL-10 and IL-13 decreased continuously. Lung ultrastructure changes included alveolar dam-age and massive erythrocyte sedimentation and inflammatory cell exudation in alveolar cavity. Alveolar ventilation and PO2 decreased significantly,P-AO2 increased continuously and lung compliance reduced. Conclusions In the early phase after pulmonary contusion ,the expression of IL-1β and TNF-α increases while IL-10 and IL-13 de-creases,lung ultrastructure is progressively destructed and lung function is severely damaged.
ABSTRACT
Objective To discuss the value of video -assisted thoracoscope technology in diagnosis and treatment of thoracic trauma .Methods Form January 2009 to December 2013, a retrospective analysis was carried out on 43 patients with thoracic trauma .All the patients were treated with video -assisted thoracoscope technology . Results The procedure were successful and all the patients were cured out of hospital .Conclusion It is wide oper-ation indication, little harm, definite treapeutic effect, little complication and fast recovered to treat the patient with thoracic trauma using video -assisted thoracoscope technology , and it is a good choice for diagnosis and treatment in thoracic trauma.
