We investigated the protective effects of electromagnetic field（EMF）on the survival of the human renal proximal tubular cell line,HK-2,using an in vitro hypoxia/reoxygenation（H/R）injury *** survival rate of cells cultured under H/R condition declined significantly,while the intracellular reactive oxygen species（ROS）levels markedly *** 10 Hz/1 m T EMF exposure could inhibit H/R-induced cell death of HK-Z via suppression of intracellular ROS production and that this treatment might be clinically useful for the amelioration of renal ischemia/reperfusion injury.

Liver biopsy is the gold standard for evaluating the degree of liver fibrosis in patients with chronic liver disease. However, due to the many limitations of liver biopsy, there has been much interest in the use of noninvasive techniques for this purpose. Among these techniques real-time two-dimensional shear wave elastography(2D-SWE) has the advantage of measuring tissue elasticity with the guidance of B-mode images. Recently, many studies have been conducted on the application of 2D-SWE in patients with various liver diseases, and their validity has been confirmed. Here, we briefly discuss the role of 2D-SWE in patients with chronic liver diseases, particularly aspects of the examination techniques and clinical applications.
