RESUMEN
Objective:To observe the size and density of adrenal gland, and the dynamic changes in patients with COVID-19.Methods:Study sample consisted of 67 patients diagnosed as COVID-19 (COVID-19 group) and 70 normal controls. COVID-19 group were divided into two groups: ordinary cases and severe cases. The CT value and thickness of adrenal gland in the control group (uni-temporal) and the COVID-19 group (multi-temporal) were measured, the CT value of adreal/erector spinae were calculated.Results:Compared with the control group, the COVID-19 group had bigger body, medial and lateral branches of bilateral adrenal gland ( P<0.05) . There was no significant difference between the CT value of adrenal/erector spinae for the two groups. Receiver operating characteristic curve analysis showed the thickness of right medial adrenal limb in detecting diffuse adrenal hyperplasia was the best (0.881) . And there was no significant difference in the CT value of adrenal/erector spinae, thickness of bilateral adrenal body, medial and lateral branches in COVID-19 group at different times. Conclusion:The bilateral adrenal glands of COVID-19 patients were slightly swollen, adrenal body, medial and lateral branches were slightly bigger than the normal adrenal glands, but the density was normal, and there were no dynamic changes during the course of the disease.
RESUMEN
To investigate the influence of six exogenous pathogenic factors on asthma in children and to observe the changes of microscopic indexes in cold- and heat-type asthma. Logistic regression analysis was applied to analyze the influence of six exogenous pathogenic factors and the changes of serum level of IgE, eosinophil (EOS) counting, contents of third component of complement (C3) and C-reactive protein (CRP) were observed. The exogenous factors of wind, cold, damp, wind-cold mixture and cold-damp mixture were the risky factors of asthma. Serum levels of IgE and EOS were higher in cold-type asthma and serum contents of C3 and CRP were higher in heat-type asthma (P
