A 76-year-old female patient presented to the emergency department with substernal chest pain and dyspnea symptoms. She reported that the symptoms started 2 days earlier. These symptoms can arise from both cardiac and noncardiac conditions. It is difficult to ascribe chest pain and dyspnea symptoms to a single cause. Recognizing these symptoms is critical for inpatient cardiac and primary care nurse practitioners to choose the correct diagnosis and facilitate more effective treatment planning. 相似文献

目的研究长链非编码RNATHOR对宫颈癌C33A细胞生长的调控作用。方法 qRTPCR分别检测15对肿瘤组织/癌旁组织和宫颈癌细胞系C33A、siHa、正常宫颈鳞状上皮细胞H8中的LncRNA THOR表达水平。在宫颈癌细胞系C33A中,siRNA沉默LncRNA THOR后利用CCK8和平板克隆形成实验检测细胞增殖,流式细胞学实验检测细胞周期,使用western blot检测细胞周期蛋白变化。结果 qRT-PCR结果显示15例组织中12例肿瘤组织LncRNA THOR表达明显高于癌旁组织,宫颈癌细胞系C33A、siHa中LncRNA THOR表达也明显高于宫颈鳞状上皮细胞H8细胞。在宫颈癌细胞系C33A中沉默LncRNA THOR后,CCK8结果显示细胞增殖受到抑制,平板克隆形成实验表现为细胞克隆明显减少。流式细胞学周期分析发现G0/G1期细胞比值增高。western blot实验显示周期蛋白cyclinD 1和cyclinE1在蛋白水平下降,p27和p21蛋白水平增高。结论 LncRNATHOR在宫颈癌中高表达,沉默LncRNA THOR可以抑制宫颈肿瘤细胞增殖。 相似文献

Amelanotic melanoma is a rare melanoma subtype, and it is even more rare when it occurs at an acral site. We here present a case of a nodular amelanotic acral melanoma (NAAM) occurring on the heel of an 83‐year old female. It presented as an ulcerated pink nodular growth on the heel, which clinically mimicked other nodular non‐pigmented lesions, causing a delay in diagnosis until it was biopsied. This case is a demonstration of the critical importance to include NAAM in the differential diagnosis of nodular non‐pigmented skin lesions as to avoid delay in diagnosis and disease progression, in which early detection can provide the most modifiable prognostic factor. 相似文献

Although the concept of ‘conflict of interest’ (COI) arises in many contexts in healthcare, it is often poorly understood, and commonly accepted, definitions are often circular, self‐contradictory and unable to provide procedural guidance. To overcome such confusion and imprecision, we offer a reformulation of COI that carefully defines interests, clarifies their scope and articulates a simple, non‐punitive approach to managing them. We define an ‘interest’ as ‘a commitment, goal, obligation or duty related to a particular social role or practice’. We show how in a particular setting multiple interests can be at play, which can be either financial or non‐financial, with the latter often being the most potent drivers of behaviour. We define a ‘conflict of interest’ as the condition that arises when two coexisting interests directly conflict with each other: that is, when they are likely to compel contrary and incompatible outcomes. COI therefore reflect objective states of affairs rather than internal mental states; they do not imply moral error; and they are identified through public rather than private processes involving ethical dialogues among relevant stakeholders. Once a COI has been identified, responses must be determined based on the seriousness of the conflict and the conditions that generated it. Such responses may be minimal or they may require a formal disengagement from one of the conflicting interests. The framework described, reflects the rich diversity of interests in modern societies, is universally applicable and provides simple, readily applicable guidelines for the identification and management of conflicts arising between them. 相似文献
