乳腺癌根治术患者miRNA-23a表达水平与术后复发转移的关系

open access: yesZhongguo shiyan zhenduanxue, 2018
目的探讨乳腺癌根治术患者miRNA-23a表达水平与术后复发转移的关系。结果选取2013年3月至2016年3月本院收治的乳腺癌根治术患者160例,依据2年内复发转移情况分为复发组(n=50例)和未发组(n=110例),采用实时荧光定量聚合酶联反应法(RT-PCR)检测miRNA-23a表达水平,分析miRNA-23a表达水平与术后复发转移的关系。结果单因素分析结果显示,复发组和未发组肿瘤类型、直径、TNM分期、淋巴结转移、雌激素受体(ER)和孕激素受体(PR)、miRNA-23a表达水平比较 ...

Structured decision‐making as a framework to incorporate social equity into conservation decisions

open access: yesConservation Biology, EarlyView.
Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.

急性髓系白血病微小残留病检测的临床意义

open access: yesZhongguo shiyan zhenduanxue, 2011
目的探讨微小残留病(MRD)检测在急性髓系白血病预测复发及指导治疗的临床意义。方法选择32例初治急性髓系白血病(除外M3)患者128份标本,利用多参数流式细胞术(FCM)进行微小残留病检测,CD45/SSC设门,选择2-4组四色抗体组合,从诱导化疗后第21天开始,每1-3个月监测一次。结果按照首次诱导治疗后第21天MRD水平将32例AML分为高(MRD>1×10-2)、中(1×10-2>MRD>1×10-4)、低(MRD1×10-2组2年复发率最高 ...

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods

open access: yesConservation Biology, EarlyView.
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

动态监测微小残留病对B-ALL预后的临床意义

open access: yesZhongguo shiyan zhenduanxue, 2013
目的探讨微小残留病(MRD)监测在B急淋(B-ALL)复发预测及指导治疗中的临床意义。方法选择2008年1月到2012年7月32例初治急性B淋巴细胞白血病160份骨髓标本,利用四色多参数流式细胞术(FCM)进行微小残留病检测。以CD45/SSC设门,选择2-3组四色抗体组合,从诱导化疗第33天开始,每1-3个月监测MRD一次,动态监测MRD变化与白血病复发的关系。结果按照诱导治疗第33天的MRD水平分成三组,高(MRD>1×10-2),中(1×10-2≥MRD≥1×10-4),低(MRD10 ...

Using the capabilities approach to achieve people‐centered conservation

open access: yesConservation Biology, EarlyView.
Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

Genomics‐informed management of ex situ populations

open access: yesConservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Optimizing biodiversity offsetting for habitat succession and colonization dynamics

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

Synthesizing Empirical Research on Learner Metacognition in Second Language Writing

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

PCNA和DNA含量估测腮腺混合瘤增殖活性

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1997
摘 要 为了评价增殖细胞核抗原( PCN A)表达和DN A含量在研究腮腺混合瘤细胞增殖活性中的价值, 对60 例良性无复发、复发和恶性腮腺混合瘤用PCN A免疫组化染色技术和流式细胞测量术作PCNA测定和 DN A含量测量。结果显示PCNA表达在各组间和高S期细胞比率( S PF)在无复发和复发组间有显著差异;恶性 混合瘤组与良性无复发组或复发组间有显著差异; PCN A表达与高SPF呈显著性正相关关系。提示PCN A表达 和DN A含量均能反映良恶性混合瘤细胞增殖活性 ...
