Research progress on the mechanism,and treatment of COVID-19 related pulmonary fibrosis
COVID-19 is an acute respiratory infectious disease caused by SARS-CoV-2 infection.With the recent normaliza-tion of the COVID-19 epidemic,imaging and pathological studies of COVID-19 patients have shown that some patients can devel-op pulmonary fibrotic changes after SARS-CoV-2 infection,and COVID-19-associated pulmonary fibrosis is becoming an impor-tant influencing factor affecting the quality of patients' prognostic survival,which is a serious threat to the life and health of pa-tients.At present,the pathogenesis of COVID-19-associated pulmonary fibrosis has not been clarified,and the treatment plan is mostly based on the previous experience in the diagnosis and treatment.In this paper,we summarize the mechanism of lung injury and fibrosis after SARS-CoV-2 infection and the related treatment plan,to provide a certain reference for the prevention,treat-ment and intervention of the clinic.
