分子分析通过定义新肿瘤实体和在已分类肿瘤类型中的确认复发性基因突变,从而重塑高级别鼻窦肿瘤的格局。鼻窦畸胎癌肉瘤(TCS)是一种罕见的高侵袭性肿瘤,混有畸胎瘤、癌和肉瘤成分,目前仍对该病知之甚少。因TCS的多表型分化引发对其组织起源的持续争议,并导致与其他几种恶性肿瘤在诊断上有重叠。

The aim of this study is to evaluate the internal corrosion process on X52 and X80 steels/real petroleum interfaces containing condensed hydrocarbon plus oilfield-produced water,which were subjected to stimulated emulsions using 50/50 vol ratio mixtures at 45℃,different hydrodynamic conditions,1 h,and 24 h.A washing process by using deionized water was proposed to simulate and identify the corrosiveness of the hydrocarbon phase after 24 h of exposure *** characterization by electrochemical impedance spectroscopy and the monitoring of the polarization curves indicated that X80 steel/oilfield-produced water interfaces were more susceptible to corrosion than X52 steel exposed to oilfield-produced *** combined speed rotation of 600 rpm using a magnetic stirrer+600 rpm using a rotating disk electrode decreased the corrosion rate on X52 *** stimulated emulsions made of hydrocarbon+oilfield-produced water and hydrocarbon+deionized water at 24 h increased the corrosion rate on X80 steel(0.34 mm/year and 0.43 mm/year,respectively),promoting the formation of erosion and pitting *** types of corrosion depended mainly on the physicochemical properties of the hydrocarbon,oilfield-produced water,exposure times,and hydrodynamic systems in which the hydrocarbon was studied.

loneliness is classically defined as a result of perceiving a discrepancy between the desired quantity and quality of one's social life and actual social relationships(Perlman and Peplau,1984).lifespan research has indicated older adults are among the highest risk for experiencing loneliness because their social network size decreases more frequently than that of younger adults.

骨外成釉细胞瘤样尤文肉瘤(AlES)是一种罕见肿瘤,除了具有明显的上皮样分化,包括弥漫表达CK和p40外,还显示特征性的EWSR1-FlI1基因易位。迄今为止所报道的AlES多见于头颈部,可酷似小蓝圆细胞肿瘤。由于AlES在形态学上很难与涎腺的基底细胞样癌鉴别,为此,作者选取10例发生在涎腺的AlES进行研究,旨在提高对该肿瘤特征的认识。

甲状腺畸胎瘤是一类罕见肿瘤,具有广泛的临床病理谱系。尽管良性和未成熟畸胎瘤主要发生于婴幼儿和少年,通常预后良好,但恶性畸胎瘤多发于成人,且呈侵袭性病程。其临床进展和预后的巨大差异提示良性、未成熟性畸胎瘤和恶性畸胎瘤可能是独立的实体肿瘤,而非不同级别的单一肿瘤。然而,迄今关于甲状腺畸胎瘤分级的组织发生以及分子特征的报道较少。
