Multimodal imaging study of hepatic perivascular epithelioid cell tumors: a case report.

Hepatic perivascular epithelioid cell tumors (PEComas) are rare interstitial tumors that are often misdiagnosed as hepatocellular carcinomas due to their unique vascular enhancement patterns. Herein, we present a case of a 61-year-old man who was incidentally found to have a lesion in the left medial segment of the liver during a chest computed tomography (CT) examination performed 4 days prior to his presentation for chest discomfort. Imaging revealed solid components with density similar to that of normal liver tissue and areas of low-density adipose tissue within the lesion.

The influence of flow distribution strategy for the quantification of pressure- and wall shear stress-derived parameters in the coronary artery: A CTA-based computational fluid dynamics analysis.

For image-based computational fluid dynamics (CFD) analysis to characterize the local coronary hemodynamic environment, the accuracy depends on the flow rate which is in turn associated with outlet branches' morphology. A good flow distribution strategy is important to mitigate the effect when certain branches cannot be considered. In this study, stenotic coronary arteries from 13 patients were used to analyze the effect of missing branches and different flow distribution strategies.

[Effects of Salvia miltiorrhiza on oxidative stress and microinflammatory state in patients undergoing continuous hemodialysis].

Objective: To investigate the effects of Salvia miltiorrhiza (SM) on oxidative stress and microinflammatory state in patients undergoing continuous hemodialysis (CHD).

Methods: Thirty-six patients who had received CHD for over half a year were assigned into the routine CHD group (18 cases) and the treated group treated with routine CHD plus SM (18 cases). Meanwhile, 18 healthy adults were taken as the normal control.
