摘要新型冠状病毒感染肺泡上皮细胞后，通过直接杀伤和过度炎症反应等多种机制共同作用造成机体肺组织的损伤。本文通过总结新型冠状病毒肺炎的临床表现、CT影像学改变及其对患者近远期肺功能的影响，对疫情期间与疫情之后非疫区胸外科的临床工作提出建议，以期使胸外科患者得到积极有效的治疗。

abstractsIn this paper, the mechanism of destroying human alveolar epithelial cells and pulmonary tissue by 2019 novel coronavirus (2019-nCoV) was discussed firstly. There may be multiple mechanisms including killing directly the target cells and hyperinflammatory responses. Secondly, the clinical features, CT imaging, short-term and long-term pulmonary function damage of the 2019 coronavirus disease (COVID-19) was analyzed. Finally, some suggestions for thoracic surgery clinical practice in non-epidemic area during and after the epidemic of COVID-19 were provided, to help all the thoracic surgery patients receive active and effective treatment.
