RESUMO
Objective:To analyze and compare the differences between the epidemiological data and clinical indicators of confirmed and suspected undiagnosed cases of COVID-19 in Changning District， Shanghai. Methods:A retrospective comparative study was conducted. We included 20 confirmed and 34 suspected but undiagnosed COVID-19 cases from January 20 to February 29， 2020. We analyzed the differences in epidemiological history， early clinical symptoms， blood routine indicators， and clinical imaging characteristics between the two groups. Results:The epidemic status of COVID-19 in Changning District of Shanghai was mainly imported， and most cases were promptly confirmed. Early clinical symptoms of confirmed and suspected undiagnosed cases often manifested as respiratory symptoms such as fever and dry cough. Compared with the confirmed cases， the cell counts of leukocytes， eosinophils， and neutrophils in suspected undiagnosed cases were significantly higher. Also， the concentration of serum C-reactive protein in suspected cases was higher than that in confirmed cases （P=0.230）. The clinical imaging manifestations of confirmed cases were mainly ground glass opacity （GGO） scattered in both lung leaves， while the suspected undiagnosed cases mainly manifested as plain patch opacity， and the distribution of GGO was more irregular. Conclusion:There exists significant difference in blood routine indicators and clinical imaging features between confirmed and suspected cases of COVID-19.
RESUMO
Objective To study the relationship between microalbuminuria and inflammation media of C-reactive protein(CRP) and interleukin-6(IL-6) in type 2 diabetes mellitus,and to explore the clinical significance.(Methods)Ninety-six patients with type 2 diabetes mellitus were divided into 3 groups according to the urine albumin excretion rate(UAER): normal albuminuria group(NA),microalbuminuria group(MA) and clinical proteinuria group(CP).The serum levels of CRP,IL-6,fasting plasma glucose,creatinine and fasting insulin were measured in all the cases. Results The levels of CRP and IL-6 in MA group were significantly higher than those in NA group(P
