Gliomas are the most common primary intracranial tumors in adults. Anaplastic gliomas (WHO grade III) and glioblastomas (WHO grade IV) represent the major groups of malignant gliomas in the brain. Several diagnostic, predictive, and prognostic biomarkers for malignant gliomas have been reported over the last few decades, and these markers have made great contributions to the accuracy of diagnosis, therapeutic decision making, and prognosis of patients. However, heterogeneity in patient outcomes may still be observed, which highlights the insufficiency of a classification system based purely on histopathology. Great efforts have been made to incorporate new information about the molecular landscape of gliomas into novel classifications that may potentially guide treatment. In this review, we summarize three distinctive biomarkers, three most commonly altered pathways, and three classifications based on microarray data in malignant gliomas.

增强对流输注 (CED) 是一项颇具前景的技术,其借助压力驱动流来增强输注药物进入细胞间隙的穿透力。为进一步提升CED的药物分布容积,笔者发明了一种可产生局部亚致死热量的光纤微针装置。本文试图在琼脂糖组织模型中对该技术进行定量表征。在15 °C、20 °C、25 °C和30 °C的恒温条件下,染料的输注在质量分数为0.6%的琼脂糖组织模型中进行分析。输注指标通过自定义阴影成像技术和图像处理算法进行定量。利用所获数据构建一个分布容积的经验预测时序模型作为组织模型温度的函数。接下来通过一组概念验证实验来评估液体输注时新型光纤装置产生局部光加热的能力。恒温输注显示温度和分布容积呈正相关,在100 min时,在30 °C恒温条件下体积扩散是在15 °C恒温条件下的7倍。在光加热 (1064 nm,500 mW) 过程中,输注呈现相似的效果:与对照组 (0 mW) 相比,输注体积在4 h时增大了3.5倍。本文的分析和结果为体积扩散的热介导增强提供了特征描述及新思路。

Norepinephrine transporter (NET) transfection leads to significant uptake of iodine-131-labeled metaiodobenzylguanidine (131I-MIBG) in non-neuroendocrine tumors. However, the use of 131I-MIBG is limited by its short retention time in target cells. To prolong the retention of 131I-MIBG in target cells, we infected hepatocarcinoma (HepG2) cells with Lentivirus-encoding human NET and vesicular monoamine transporter 2 (VMAT2) genes to obtain NET-expressing, NET-VMAT2-coexpressing, and negative-control cell lines. We evaluated the uptake and efflux of 131I-MIBG both in vitro and in vivo in mice bearing transfected tumors. NET-expressing and NET-VMAT2-coexpressing cells respectively showed 2.24 and 2.22 times higher 131I-MIBG uptake than controls. Two hours after removal of 131I-MIBG-containing medium, 25.4% efflux was observed in NET-VMAT2-coexpressing cells and 38.6% in NET-expressing cells. In vivo experiments were performed in nude mice bearing transfected tumors; results revealed that NET-VMAT2-coexpressing tumors had longer 131I-MIBG retention time than NET-expressing tumors. Meanwhile, NET-VMAT2-coexpressing and NET-expressing tumors displayed 0.54% and 0.19%, respectively, of the injected dose per gram of tissue 24 h after 131I-MIBG administration. Cotransfection of HepG2 cells with NET and VMAT2resulted in increased 131I-MIBG uptake and retention. However, the degree of increase was insufficient to be therapeutically effective in target cells.

目的:探讨BPA(2,2-双(4-羟基苯基)丙烷,Bisphenol A)浓度和温度对胶质瘤细胞系摄取和析出10B的影响。方法:将C6和U251两种胶质瘤细胞系,及大鼠正常脑胶质细胞培养在含不同浓度BPA(10B浓度分别为20、40、60、80、100 μg/mL)的培养基中24 h后,采用感应耦合等离子体原子发射光谱(ICP-AES)法测定细胞内硼的含量;将C6细胞培养在含不同浓度BPA的培养基中培养24 h后,更换为不含10B培养基,在不同温度条件(4、25、37 ℃)下继续培养,并分别于换液后的1、2、3 h,用ICP-AES方法检测细胞内的硼含量。结果:细胞内硼浓度随培养基中BPA浓度的增加而增高,胶质瘤细胞内10B浓度约为正常胶质细胞的2.2倍;温度越高,细胞内硼析出速度越快。结论:BPA对胶质瘤细胞系具有一定亲和力;细胞对10B的析出速率具有温度依赖性。
