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。     

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。     

UPLC-MS/MS法评价不同绿茶膳食补充剂主要成分特征

目的:比较不同绿茶膳食补充剂中主要活性成分的含量,为绿茶膳食补充剂产品的质量控制提供依据。方法:运用UPLC-MS/MS方法鉴定绿茶膳食补充剂中的主要成分,HPLC法测定主要成分的含量,最后用主成分分析和层序聚类分析评估绿茶膳食补充剂产品的变异性。结果:12种不同绿茶膳食补充剂中的主要成分为儿茶素、表焙儿茶素、咖啡因、表儿茶素、表焙儿茶素-3-没食子酸酯,儿茶素没食子酸酯、表儿茶素-3-没食子酸酯,其含量差异较大,主成分分析和层序聚类分析结果显示12种产品根据主要成分的含量可分为4个组群。结论:不同绿茶膳食补充剂质量差异较大,高度变异可能导致变量生物学效应,因此有必要使绿茶膳食补充剂标准化,发现更多潜在益处。     

Systematic review of optical coherence tomography usage in the diagnosis and management of basal cell carcinoma

Optical coherence tomography (OCT) is a noninvasive imaging tool used in vivo in real time for diagnosis, treatment delineation and monitoring of basal cell carcinoma (BCC). Features of BCC on OCT have been widely described and reviewed. However, the diagnostic accuracy of OCT in these various applications is unclear. We systematically reviewed the literature to assess the accuracy of OCT in diagnosis and management of BCC using the Embase and Medline databases. In total 179 unique references were identified in the initial search, of which 22 studies with 556 histologically proven BCCs were eligible. Assessment of the quality of eligible studies was undertaken using the STROBE criteria. Data extraction and quality assessment were performed independently by the two authors. This systematic review provides an overview of the clinical applications of OCT in the diagnosis and management of BCC. OCT has been suggested to be useful in the diagnosis, treatment planning and treatment monitoring of BCC. As the technology improves and its utility increases, further studies with good methodological quality will be needed to implement OCT into daily practice.
