Purpose/Background:Langerhans cell histiocytosis(LCH) is an uncommon monoclonal proliferation of the unique dendritic cells of the skin known as Langerhans cells. The LCH frequently occurs as single or multiple bone lesions;jaws being involved in 10%–20% of cases, with a preference for the mandible. It is mainly a disease of the children with the incidence ten times more as compared with the adults. The present study aims to evaluate the efficacy of triamcinolone acetonide in the management of LCH.

口咽癌是头颈鳞癌中重要的癌种之一,与人类乳头瘤状病毒(human papillomavirus, HPV)感染有关,其发病率逐年上升。但在临床治疗过程发现,HPV 阳性口咽癌患者整体预后好于 HPV 阴性患者。目前,导致这一现象发生的分子机制尚不明确。本研究利用 TCGA 数据库,对 HPV 阳性和阴性患者的免疫细胞浸润和效应功能以及新抗原负荷进行了生物信息学分析。结果发现,HPV 阳性患者的总体生存率比 HPV 阴性患者显著提高。对肿瘤组织中的免疫细胞相对丰度进行分析显示,HPV 阳性患者的 CD8+ T 细胞较 HPV 阴性患者显著提高,其效应分子 IFN-γ和 Granzyme B 表达量显著升高。同时对新抗原数目进行分析发现,HPV 阳性患者肿瘤组织中新抗原较 HPV 阴性患者低。本研究结果为 HPV 相关口咽癌的治疗提供了一定的基础理论支撑。

The free-energy principle entails the Bayesian brain hypothesis that can be implemented by many schemes considered in this field. The combination of multimodal brain imaging and free-energy minimization has shown promise in unraveling complex brain dynamics and understanding the interactions among distinct brain regions. The Bayesian mechanics of brain computing gives a unique route to understanding authentic(neuromimetic) intelligence and, more importantly, points towards the development of brain-inspired intelligence.
