Research progress on the role of astrocytes in radiation-induced brain injury / 中华放射肿瘤学杂志

Radiation-induced brain injury (RBI) is one of the complications after radiotherapy for head and neck malignant tumors, which seriously affects the quality of life of patients. The pathophysiological mechanism of RBI is not completely clear. Current studies suggest that it is involved in a variety of cells in the central nervous system (CNS), whereas astrocyte, as the largest number of glial cells in the CNS, plays an important role in maintaining the CNS homeostasis and responding to CNS injury. In this article, the role of astrocytes in RBI was reviewed.

Transcatheter aortic valve implantation: Present and development trend / 中南大学学报(医学版)

Currently,although surgical aortic valve replacement (SAVR) is still the golden standard in treatment of severe aortic stenosis according to the guideline,transcatheter aortic valve implantation (TAVI) is gradually becoming a common treatment for patients who are prohibitive or in high risk for SAVR.Recently,the valve manufacturers,including medical companies in China,are making their utmost to develop valve device,leading remarkable results achieved by TAVI.With the complications being controlled,TAVI displays promising future.It is likely that TAVI is expected to become a substitute for SAVR to treat patients with aortic stenosis or even aortic regurgitation.
