BRCA-1、ERCCmRNA表达水平与在大肠癌铂类化疗预后的相关性研究
目的探讨以铂类为基础化疗方案的大肠癌患者中乳腺癌敏感蛋白Ⅰ型(BRCA-1)、核苷酸切除修复交叉互补基因(ERCC-1)表达与患者临床病理特征的关系及其预后意义。方法采用实时荧光定量逆转录聚合酶联反应(RT-qPCR)检测54例大肠癌患者组织标本中BRCA-1、ERCCmRNA表达,比较其表达水平与患者临床病理特征和生存时间之间的关系。结果 (1)BRCA-1mRNA低表达20例(37.04%),高表达34例(62.97%)。BRCA-1mRNA表达水平与淋巴结转移及临床分期有关(P=0.037,P=0.

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

ABSTRACT Translating local research into English as a lingua franca (ELF) connects local scholarship with global readership, but this process remains constrained by language barriers. Large language models (LLMs) offer advanced accessible solutions, but their responsible integration into academic translation requires a deeper understanding of the ...

Narrative power in the narrative policy framework
Abstract The Narrative Policy Framework lacks clear and empirical explanations of power. Yet, the study of narratives is inherently the study of power in shaping policy outputs and decisions. We develop a conceptual model positing that expressions of power (power to, with, and over) may be discovered in narrative constructs (e.g., narrative structure ...
