  • 新型抗炎介质消退素的生物效应及机制

    消退素是一类具有抗炎效果的内源性多不饱和脂肪酸衍生物,可分为E类消退素、D类消退素、阿司匹林触发消退素等类型。消退素在多种组织器官的炎症中显示出较强的抗炎效果,同时还具有镇痛、抗纤维化、改善胰岛素抵抗等作用。而核因子-κB、丝裂原活化蛋白激酶、蛋白激酶B等通路可能介导上述生物效应。现就消退素的生物效应及机制的最新研究进展作一综述。

  • From Microdosimetry to Nanodosimetry--the Link between Radiobiology and Radiation Physics

    The link between micro- and macro-parameters for radiation interactions that take place in living biological systems is described in this paper. Meanwhile recent progress and development in microdosimetry and nanodosimetry are introduced, including the methods to measure and calculate these micro- or nano-parameters. The relationship between radiobiology and physical quantities in microdosimetry and nanodosimetry was presented. Both the current problems on their applications in radiation protection and radiotherapy and the future development direction are proposed.
