Impact of individual characteristics on sonographic IVC diameter and the IVC diameter/aorta diameter index.

Background: The inferior vena cava (IVC) parameters, including its diameter and collapsibility index have been evaluated for fluid status for over 30 years, but little is known about the impacts of patient characteristics on IVC parameters. The purpose of this study was to explore the relationships between individual patient characteristics and IVC parameters in healthy Chinese adult volunteers.

Methods: From February 2012 to May 2012, 216 healthy volunteers older than the age of 18 years were consecutively enrolled in our study.

[Detection of cardiac troponin and high-sensitivity C reactive protein in children with viral myocarditis].

Objective: To investigate the changes of cardiac T troponin (cTnT) and high-sensitivity C reactive protein (hs-CRP) in children with viral myocarditis (VMC).

Methods: Forty children with VMC were examined for cTnT, hs-CRP, and creatine kinase MB (CK-MB) levels.

Results: Children with VMC had significantly higher cTnT, hs-CRP and CK-MB levels than the control group on admission (P<0.
