Fig.1 Basic information and clinical features of 64 cases of COVID-19 in Wenzhou In age, 1(1.56%) under 20, 58 (90.63%) from 20-60, 5 (7.81%) above 60; in gender, 36(56.25%) were male and 28(43.75%) were female; in generation, 33 persons were classed as Generation 1 (Gen.1); 25 cases as Gen.2; 4 cases as Gen.3; 2 cases lost contact history; in severity classification, 51 cases light, 11 severity and 2 critical.
Fig.2 Clinical indexes of 64 cases of COVID-19 in Wenzhou WBC, NEC, LC, PLT, Hb, K+, Na+, LDH, CRP, OI (Oxygenation Index) and D-dimer had statistically significant (p<0.001), so did AST(p<0.05). The indexes decreased in patients infected with COVID-19 including WBC, LC, PLT, K+, Na+, OI, while LDH, CRP, D-dimer would be at higher level. BNP and TNI were normal, and not shown.
Fig.3 The distribution of data of indexes correlated to disease severity Severity had the positive correlation with D-dimer, and age, temperate, LDH, while had negative correlation with LC and OI.
Fig.4 CT changes between primary diagnostic with before discharged in vary degrees of COVID-19 infection There were cloud turbulence and ground-glass high density scattered in the periphery of both lungs in most light cases; local patchy consolidation and Broncho pneumatic signs could be seen. The severe cases had more diffuse density, solid or stripy lesion as well as local fibrosis formation in the lower leaves of lungs.
Fig.5 Close obvious of LDH\ LC\ K+ changes during hospitalization in vary degrees of COVID-19 infectionLC, LDH and K+ could be good biomarkers to predicting and monitoring the progress of disease.
