热疗对肿瘤免疫微环境中免疫细胞及免疫相关细胞因子的影响

随着对肿瘤热疗和肿瘤免疫微环境(TIME)的深入研究,近年来热疗对TIME的作用越来越受到学者们的重视。本文就目前国内外研究进展,对热疗与TIME中几类主要免疫细胞和免疫相关细胞因子的影响及作用机制作一综述。全面而透彻的了解热疗对TIME的调控作用,有助于为肿瘤治疗提供新的思路和方法。     

Adolescent neighborhood quality predicts adult dACC response to social exclusion

Neuroimaging studies using the social-exclusion paradigm Cyberball indicate increased dorsal anterior cingulate cortex (dACC) and right insula activity as a function of exclusion. However, comparatively less work has been done on how social status factors may moderate this finding. This study used the Cyberball paradigm with 85 (45 females) socio-economically diverse participants from a larger longitudinal sample. We tested whether neighborhood quality during adolescence would predict subsequent neural responding to social exclusion in young adulthood. Given previous behavioral studies indicating greater social vigilance and negative evaluation as a function of lower status, we expected that lower adolescent neighborhood quality would predict greater dACC activity during exclusion at young adulthood. Our findings indicate that young adults who lived in low-quality neighborhoods in adolescence showed greater dACC activity to social exclusion than those who lived in higher quality neighborhoods. Lower neighborhood quality also predicted greater prefrontal activation in the superior frontal gyrus, dorsal medial prefrontal cortex and the middle frontal gyrus, possibly indicating greater regulatory effort. Finally, this effect was not driven by subsequent ratings of distress during exclusion. In sum, adolescent neighborhood quality appears to potentiate neural responses to social exclusion in young adulthood, effects that are independent of felt distress.     

新课标下提高《医用高等数学》课堂教学效果

在当前高中新课标不断改革的背景下,高中数学中增加如导数、积分等属于医用高等数学知识体系的内容,而删减了如反三角函数等医用高等数学中所必须的知识。这势必就会带来医用高等数学课程与高中数学课程在教学内容及教学方法上的不协调,从而出现部分学员高中数学跟不上,大学医用高等数学听不懂的现象。同时,授课教员在教学过程中也常常被这种现状所困扰。本研究根据以上问题,结合实际的调查结果及学员的实际需求,主要从医用高等数学教学内容的设计出发,探讨如何合理设计教学内容与教学方法,以增强学员学习医用高等数学的积极性与主动性,从而进一步提高医用高等数学课堂教学效果。
