本研究致力于探索越南汉越词四字格成语与汉语四字格成语之间的相似性与差异性,并分析这些异同对越南学生学习汉语成语的影响。通过深入研究,本论文旨在为越南学生提供有效的学习参考,同时增进对中越文化交流与理解。研究的初衷源于对当前学术界在汉越词四字格成语与汉语四字格成语对比研究领域的相对匮乏。现有研究大多集中于汉越成语的整体特征,而对四字格成语的细节和深入分析尚显不足。为填补这一空白,本研究梳理和统计《汉越成语词典》等越南语料库中的相关成语,力求提供全面且细致的分析视角。在对比分析方面,本文着重考察了越南语汉越四字格成语与汉语四字格成语在语素和语义上的异同。通过研究笔者发现,尽管许多成语在结构和语素上保持一致,但在语义上却常呈现出显著的差异。通过问卷调查,本研究探讨了汉越四字格成语对越南学生学习汉语四字格成语的影响。结果显示,虽然汉越成语在学习过程中具有积极作用,但也存在一定挑战。基于这些发现,本文进一步提出了针对越南汉语的学习及教学建议。这些建议旨在帮助学生克服学习过程中的困难,提高学习效率,并为教师提供了实用的教学策略。这一部分的研究不仅对理解汉越语言间的相互作用具有重要意义,也为汉语作为第二语言教学提供了新的视角。整体而言,本文有效填补了学术研究的空白,并结合理论与实践为越南汉语教育提供了实用指导。通过对比分析和问卷调查,本研究深入分析了汉越四字格成语与汉语四字格成语之间的相似性与差异性,探讨了越南学生在汉语学习中遇到的挑战,并提出了相应的解决策略。这些发现不仅具有学术价值,也为教学实践提供了重要的参考。

目的：评价电针联合其他药物在甲状腺全切除术中提供镇痛和稳定血流动力学参数的有效性和安全性。方法：该随机对照试验囊括了100例患者，这些患者于2022年10月至2023年10月在越南国立针灸医院接受了甲状腺全切除术。患者被随机分为了两组。电针镇痛组（EA）对合谷穴（LI 4）、内关穴（PC 6）、水突穴（ST 10）、缺盆穴（ST 12）、翳风穴（SJ 17）5个穴位进行了电针刺激，对照组患者进行了双侧浅表颈丛神经阻滞。主要结局包括两组患者的镇痛水平和围手术期生命体征。此外，测定了EA组患者电针前后的疼痛阈值和血清β-内啡肽水平。结果：EA组和对照组分别有86%和76%的患者达到完全镇痛（A级），两组间无显著差异（P=1.00）。EA组患者接受EA后平均疼痛阈值翻倍（648.7(77.4) g/s vs. 305.3 (45.3) g/s, P <0.001），平均血清β-内啡肽水平增加了约13.5pg/m L(P <0.001)。所有患者在整个手术过程中的血流动力学维持稳定。结论：EA联合其他药物刺激了5个穴位，LI 4、PC 6、ST 10、ST 12和SJ 17，在甲状腺全切除术中耐受良好，有效地维持了适当的镇痛水平和血流动力学稳定性。

Objective: To examine the in vitro and in vivo anti-inflammatory effects of the alkaloid enriched extract(ELA) from the roots of Eurycoma longifolia. Methods: The in vitro antiinflammatory effects of ELA were evaluated by examining its inhibitory activities against nitric oxide(NO) production and inducible nitric oxide synthase(iN OS) and cyclooxygenase2(COX-2) expressions in lipopolysaccharide(LPS)-stimulated RAW264.7 cells. The level of NO produced in the culture media was determined by Griess method. The i NOS and COX-2 protein expressions were analyzed by Western blot. The in vivo effect of ELA was evaluated on LPS-induced septic shock in mice model. Mice mortality was monitored for5 days after injection of LPS. The chemical contents of the ELA were determined by using various chromatographic and spectroscopic techniques. Results: The ELA was found to exhibit a significant anti-inflammatory effect in both in vitro and in vivo models. The results demonstrated that ELA dose-dependently inhibited LPS-induced NO production as well as the protein iN OS and COX-2 expressions. In the septic shock model, ELA dose-dependently protected mice from LPS-induced mortality. Further study on the isolated components of ELA indicated that 9,10-dimethoxycanthin-6-one may contribute significantly to the antiinflammatory effects of the extract. Conclusions: These results suggest that ELA exhibits the anti-inflammatory activity via suppression of pro-inflammatory mediators such as NO, iN OS,and COX-2 and protects mice from LPS-induced mortality in septic shock model.

补语是中文语法中的一个重要知识点,也是一个相对难的语法学习点,特别是对于越南学习者,因为在越南语中没有相似的结构,所以对于他们来说补语的难度更大。中文有着丰富而复杂的补语系统,其中,状态补语在汉语中使用频率高、结构复杂、语义繁多、语境因素强,被汉语教学界视为汉语教学的重点和难点。笔者是越南留学习者,也曾经经历过汉语学习初中级这段时间,因此特别理解初中级汉语学习者习得过程中的困难与学习过程中的需求。本文主要收集了越南胡志明市师范大学中文系初中级汉语学习者在使用汉语状态补语时产生的偏误,并进行了详细的偏误研究和分析。通过调查与分析,笔者旨在找出更科学有效的汉语状态补语教学方法。本文先对研究背景、研究目的和意义、研究方法等进行说明,对状态补语的语料搜集情况进行概述,本文选择《HSK标准教材2、3》中的状态补语为考察对象,以偏误分析理论、中介语理论和对比分析理论为指导,并采用调查分析、个别访谈等方法进行研究。其次对国际中文教学中的状态补语进行研究综述与相关界定,主要总结了状态补语的本体研究和国际中文教学中的状态补语研究,分析了状态补语研究现状。笔者还对初中级越南学习者的调查问卷和试题进行整理和分析,主要针对胡志明市师范大学中文系的初中级学习者,通过调查问卷与访谈进行状态补语偏误语料的搜集与统计。第四部分对初中级越南学习者学习状态补语的偏误进行了分类,共分为五类。随后,对初中级越南学习者学习汉语状态补语产生偏误的原因进行了分析,分为客观因素和主观因素,并探讨了学习者们回避状态补语学习的现象及其原因。最后是对状态补语的教学思考,针对引起偏误的原因提出具体的教学建议,并设计了部分教学计划,同时提供了《HSK标准教程1、2、3》中状态补语动词相关的参考例句和练习。希望本文研究成果能为越南初中级汉语语法教学提供启示,并能在实际教学中提高教学效果、降低学习难度、减轻教学压力,从而找到最佳的汉语状态补语教学途径。同时,也期望本研究能够为国际中文教学和研究贡献一份力量。

吸引外商直接投资是推进国家和地区经济发展的重要来源,在当前全球化总体发展趋势中,吸收外商直接投资被公认为是全球各国使用其独特优势赢得发展的一种可行方式。对于越南这样国内经济中的资金积累不足的发展中国家而言,吸引外来资金,尤其外商对内直接投资,对于投资开发和地方发展极为重要。可以说,外商直接投资是帮助越南经济快速飞腾的巨大推力。在革新开放的背景下,越南中央政府近年来颁布了许多促进经济发展的方针政策,特别是发展经济区的政策,来吸引外资。广宁省作为越南吸引外资的大省,是越南北部边境省份之一,拥有许多发展的优势和吸引外资的便利。但是,广宁省目前的经济状况仍然比较落后,科学技术、基础设施不够发达,劳动效率低下,省内经济实力薄弱,人均收入欠佳。经济区是广宁省发展经济的重要引擎,在历经二十年的大力吸引外商投资以后,广宁省的经济区取得了一定的成绩。但是,经济区取得的成绩,外商投资的吸引和使用,与其自身的巨大潜能、优势仍不完全对称,尚未能满足广宁省社会经济的发展要求。因此,为了继续推动外商投资,本人开展了《越南广宁经济区吸引FDI对策研究》,试图通过提出与广宁省辖区内广宁经济区吸引外商投资相关的理论,分析优势、劣势和存在的困难,寻找对广宁经济区发展产生影响的问题,进而提出广宁经济区未来吸收外商投资的相应对策。本文采用综合分析与比较分析、定量分析和文献资料法等研究方法,以吸引FDI理论为基础,对越南广宁经济区的吸引FDI进行研究,首先对越南广宁经济区吸引FDI现状进行了概括,接着对广宁经济区吸引FDI存在的经济增长效应、技术进步和就业效应进行了分析,进而提出了越南广宁经济区吸引FDI存在的硬环境因素和软环境因素问题,最后结合国内外吸引外商投资的经验,提出了提升越南广宁经济区吸引FDI水平的对策建议,以提升越南广宁经济区的竞争优势和吸引FDI质量。
