Description

The clinical characteristics, chest computed tomographic (CT) scans, medicine treatment and laboratory information were collected and analyzed. All cases had finished CT scans and real-time reverse-transcriptase polymerase-chain reaction (RT-PCR) before admission and also had finished examinations after discharge from hospital per 2 weeks. The results of RT-PCR assay in all cases were negative after discharge. Clinical information included demographic data, medical history, symptoms, signs, course of the disease, length of stay in hospital, therapeutic schedule and basic disease. The characteristic of CT scans including the zone of lung lesion and CT imaging which are ground glass opacity (GGO), patch shadow, consolidation and reticular pattern. Blood tests upon admittance and in the early-stage evolution (24-48 hours) were carried out, including white blood cell (WBC) count, neutrophil count, lymphocyte count, monocyte count, platelet count and partial pressure of arterial oxygen (PaO2). According the tests, neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR) and PaO2 /FiO2 (oxygen concentration) ratio were measured.
