2019-nCoV 感染者胸部影像学与实验室指标相关性分析.

Objective　To investigate the correlation between chest CT scan and laboratory indicators in 2019-nCoV infected patients, and to provide reference for early diagnosis and treatment. Methods　Retrospective analysis was performed on 2019-nCoV infected patients admitted to the Third People’s Hospital of Kunming from February to March 2020. Patients were divided into abnormal chest CT group and normal chest CT group. Correlation analysis was conducted on CT data and laboratory related indicators. Results　The age of 9 patients with 2019- nCoV infection was positively correlated with the size of whole lung consolidation shadow and ground glass density shadow （r = 0.34, r = 0.48, P < 0.05）, and age was positively correlated with the size of whole lung lesion （r = 0.40, P < 0.05） . Pneumonia accounted for 64.1%, among which double lung disease accounted for 80.00%, unilateral disease accounted for 20.00%; There were differences in eosinophil count, CRP, CD8+ count and Rglutamylaminotransferase increase in lung CT with or without abnormality （P < 0.05）. The size of lung lesion was negatively correlated with lymphocyte count, eosinophil count, CD8+ and CD3+ count, and positively correlated with CRP and GGT. Conclusion In 2019-nCoV patients, bilateral lung lesions are common. The older the age, the more lung lesions; The lower the number of lymphocytes, the higher the number of CD8+ and CD3+, the higher the CRP and GGT, the more lung lesions, which can be used as an early warning indicator of pneumonia and severe disease.
