Chinese Clinical Named Entity Recognition with ALBERT and MHA Mechanism
Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022 Traditional clinical named entity recognition methods fail to balance the effectiveness of feature extraction of unstructured text and the complexity of neural network models. We propose a model based on ALBERT and a multihead attention (MHA) mechanism to solve this problem.

Chinese Medical Entity Recognition Model Based on Character and Word Vector Fusion
Scientific Programming, Volume 2021, Issue 1, 2021., 2021 The medical information carried in electronic medical records has high clinical research value, and medical named entity recognition is the key to extracting valuable information from large‐scale medical texts. At present, most of the studies on Chinese medical named entity recognition are based on character vector model or word vector model.

General Psychiatry, Volume 30, Issue 2, Page 119-126, July 2018., 2018 Background The incidence of depressive symptoms is higher in cancer patients. And depression can also affect the occurrence, development and outcome of cancer through the neuroendocrine‐immune‐network system. Objective To study the level of Nesfatin‐1 in the plasma and brain tissue and its role in the pathogenesis in gastric cancer comorbid with ...

Zhongguo shiyan zhenduanxue, 2021 目的探讨胃癌根治性手术前后TM4SF1(跨膜4超家族成员1)水平及病理特征变化。方法选取天津市宁河区医院2016年6月到2019年6月共收治的80例胃癌患者进行回顾性分析,所有患者均行胃癌根治术,分析胃癌患者根治术前胃癌组织及邻近非胃癌组织中TM4SF1表达,胃癌患者根治术后胃粘膜中TM4SF1水平表达与胃癌根治术前TM4SF1表达水平对比,并对比所有患者胃癌根治术前和手术1年后的临床病理特征。结果在同一切段中,TM4SF1在GC组织中呈阴性表达,在相邻非癌组织中呈阳性表达。在我们的患者队列中 ...

The Role and Mechanism of RARα in the Development of Gastric Carcinoma [PDF]
, 2016 尽管胃癌的发病率在下降，但其死亡率仍位于全球第二位。由于缺乏有效的早期诊断方法，大多数胃癌病人在确诊时已到了晚期阶段。因此亟需寻找新的胃癌诊断与治疗的分子靶点。许多研究表明视黄酸受体在肿瘤的进程中起着重要的作用，然而，RARα与肿瘤的关系尚不清楚。本论文以胃癌为研究对象，阐明RARα在胃癌发生发展中的作用及其分子机制。 本论文主要通过Q-PCR、Westernblot、IHC/ICC等方法研究胃癌组织和细胞中RARα的表达情况及其临床意义。利用MTT、细胞集落形成、裸鼠皮下异种成瘤、流式细胞术 ...

Functions and associated mechanisms of Human tumor necrosis factor-alpha-induced protein 8 family during gastric cancer carcinogenesis [PDF]
, 2016 胃癌是消化系统最常见的恶性肿瘤，在世界范围内，胃癌的发病率居恶性肿瘤的第四位，死亡率居恶性肿瘤的第二位。胃癌发生、发展涉及多因素、多步骤、多基因参与的复杂过程，迄今为止，胃癌的病因和发病机制尚未完全阐明。因此，对胃癌发病机制、在不同分子途径在肿瘤发生发展中的作用机制的研究，寻找特异性的生物标志分子，对于早期发现胃癌和探寻新的治疗方法，进而提高胃癌患者生存率和提升生活质量具有重要意义。 TNFAIP8家族是由肿瘤坏死因子α诱导产生的一个蛋白质家族，参与多种生物学过程 ...
