Objective To explore the death attitudes and its influencing factors among the elderly in nursing institutions. Methods A questionnaire survey on death attitudes was conducted among 593 elderly individuals in nursing institutions in Guangzhou from January 2018 to December 2022,and their possible influencing factors were analyzed. Results There were 51.9% of the elderly individuals whose death attitudes were characterized by escape acceptance,while 7.1% demonstrated natural acceptance．However,the numbers of the elderly individuals with approaching acceptance,fear of death and escape from death showed no significant statistical difference,all being lower than the number of the elderly individuals with escape acceptance．The influencing factors of death attitude included physiological and psychological factors,cultural and ideological factors,and social environment factors．The probability of physiological and psychological factors influencing death attitudes was higher than that of other factors（P<0.05）．The score for the dimension of approaching acceptance in death attitudes was higher than that for other dimensions（P<0.05）. Conclusions In nursing institutions,the majority of elderly individuals cannot naturally accept death．Most elderly individuals exhibit an attitude of escape acceptance towards death,while some exhibit an attitude of fear and escape．However,the factors influencing the elderly's attitudes towards death are mainly physiological and psychological factors．

Objective To evaluate the prognostic significance of a group of clinical indices in the patients with internal carotid artery occlusion（ICAO）. Methods From 2017 to 2022,a total of 131 patients with ICAO were enrolled．All eligible patients were divided into acute ICAO（AICAO）and chronic ICAO groups（CICAO）,which were subdivided into good and poor prognosis groups．A respective analysis was performed to identify a practical profile for the outcome prediction of the patients with ICAO. Results The overall prognosis of CIACO was good．The proportion of NIHSS score < 6 in AICAO group with good prognosis and good collateral circulation compensation was significantly higher than that in poor prognosis group,while bleeding conversion was lower than that in poor prognosis group,with statistical significance（P<0.05）．Dichotomous logistic regression analysis showed that the prognostic effects of NIHSS score,collateral circulatory compensation score,interventional initiation,hemorrhagic transformation,and subtotal occlusion on the prognosis of AICAO were statistically significant．There were no significant differences in basic information,past medical history,interventional operation between the two groups（P>0.05）. Conclusions The patients with CICAO have a better prognosis than those with AICAO．NIHSS score < 6,good collateral circulation and no-hemorrhagic transformation may have strong prognostic relevance to ICAO．High NIHSS score,poor collateral circulation and hemorrhagic transformation at the time of onset are risk factors for poor prognosis of ACAO ．

胶质瘤是颅内最常见的原发性恶性肿瘤,其分级对患者治疗方式的选择和预后至关重要。尽管目前组织病理学仍是其最为可靠的分级手段,但需通过有创性手术以获取组织样本,存在一定的风险。相较之下,磁共振成像（MRI）作为一种非侵入性影像诊断工具,在胶质瘤分级中发挥着不可或缺的作用。然而,传统MRI评估受限于医师个体主观性强和可重复性差的问题,一定程度上影响了准确的分级结果。近年来,影像组学技术的崭露头角为解决上述难题开辟了新视角,通过高通量提取影像数据特征捕捉并量化肿瘤的影像学表现,避免因主观因素而导致的不确定性,协助医师更准确地评估肿瘤的恶性程度。本文对近五年来MRI影像组学在胶质瘤术前分级预测方面的相关研究进行了简要综述,旨在为相关领域研究者提供有益的参考和借鉴,以推动MRI影像组学在临床实践中的应用。

Glioma is the most common primary malignant brain tumor,and its grading is crucial for treatment decisions and prognosis．Currently,histopathology remains the gold standard for grading,but it requires invasive procedures and carries inherent risks．In contrast,magnetic resonance imaging（MRI）,a non-invasive diagnostic tool,plays an indispensable role in glioma grading．However,traditional MRI assessment is hampered by interobserver subjectivity and limited repeatability,which compromise grading accuracy．In recent years,radiomics,a burgeoning field,has offered a promising solution to address these challenges．By extracting high-dimensional imaging data features,radiomics enables the quantification of tumor radiological characteristics and elimination of subjectivity-related discrepancies．This technology assists clinicians in more precisely assessing the malignancy of gliomas．This article summarizes relevant studies in the past five years on the application of MRI radiomics in preoperative glioma grading,aiming to provide valuable insights and guidance to researchers in the field and promote the clinician implementation of MRI radiomics．

药物治疗抵抗在临床实践中成为肿瘤治疗失败的主因。最近的研究指出,肿瘤细胞的耐药性可能源于其内部高度的细胞异质性,而这种异质性的基础则是肿瘤可塑性。肿瘤细胞可塑性可能引发一系列反应,包括对治疗的耐药性发展、免疫系统逃逸以及对周围组织和血管系统的侵袭和转移等。本文简要介绍肿瘤细胞可塑性的表现形式以及其在药物治疗抵抗的非遗传适应性机制与靶向治疗新策略。

Drug therapy resistance has emerged as a primary cause of treatment failure in cancer management．Recent research indicates that the resistance of tumor cells may stem from their high degree of intracellular heterogeneity,with the underlying basis being tumor plasticity．Tumor cell plasticity can trigger a cascade of responses,including the development of resistance to treatment,evasion of the immune system,and invasion and metastasis into surrounding tissues and the vascular system．This article provides a brief overview of the manifestations of tumor cell plasticity and its non-genetic adaptive mechanisms in drug therapy resistance,along with novel strategies for targeted treatment．
