关键词： 左甲状腺素钠片   妊娠期   甲状腺功能   糖代谢  

摘要： 目的 探究左甲状腺素钠片对妊娠期甲状腺功能衰退患者的糖、脂代谢水平及甲状腺功能的影响。方法方便选取2019年1月—2023年12月曹县人民医院62例妊娠期甲状腺功能减退的孕妇为研究对象，依据治疗方法分成对照组（n=31，常规疗法）和观察组（n=31，常规疗法+左甲状腺素钠片）。对比两组孕妇甲状腺功能指标[甲状腺激素（thyroid stimulating hormone, TSH）、甲状腺过氧化物酶抗体（anti-thyroid peroxidase antibody, TPOAb）、血清游离三碘甲状腺素（serum free triiodothyronine, FT3）、血清游离甲状腺素（serum free thyroxine, FT4）]、糖代谢水平[空腹血糖（fasting blood glucose, FBG）、空腹胰岛素（fasting insulin, FINS）]、脂代谢水平[血清总胆固醇（total cholesterol, TC）、甘油三酯（triglyceride, TG）、血清低密度脂蛋白胆固醇（low-density lipoprotein cholesterol, LDL-C）及高密度脂蛋白胆固醇（high-density lipoprotein cholesterol, HDL-C）]。结果 治疗前，两组甲状腺功能指标、糖代谢水平、脂代谢水平相比，差异均无统计学意义（P均>0.05）。治疗后，观察组TSH、TPOAb、FT3、FT4水平均优于对照组，差异均有统计学意义（P均<0.05）。观察组FBG、FINS、HOMA-IR分别为（5.22±0.43）mmol/L、（11.62±3.23）mlU/L、2.42±1.26，均低于对照组的（5.74±0.78）mmol/L、（14.52±3.57）mlU/L、3.45±1.22，差异均有统计学意义（t=3.251,3.354,3.270;P均<0.05）。观察组患者TC、TG、LDL-C各项指标均低于对照组，HDL-C指标高于对照组，差异均有统计学意义（P均<0.05）。结论 左甲状腺素钠片治疗妊娠期孕妇能够有效调节甲状腺功能，改善血糖、血脂代谢水平。

关键词： Generative AI   sustained use   digital awareness   technology adoption   consumer behavior  

摘要： The rapid integration of generative artificial intelligence (AI) into consumer markets has significantly influenced how shoppers gather and process information. However, the factors that are associated with the sustained use of AI tools for shopping decisions remain underexplored. This study addresses this gap by employing a hybrid analytical approach combining 'Partial Least Squares-Structural Equation Modeling' (PLS-SEM) and 'Artificial Neural Networks' (ANN). We integrate the 'Uses and Gratification Model' with 'Dual-Process Theory' to explore how emotional and cognitive factors, such as enjoyment, perceived accuracy, and benefit, are related to continued reliance on generative AI. The model was tested with data from 397 users, and the findings reveal significant predictors of sustained use, underscoring the importance of these variables in contributing to long-term consumer interaction with AI technologies. These insights contribute to the broader understanding of how AI can sustainably support consumer decision-making.

关键词： Theories of space   comparative education   social topology   spatial-temporalities   beyond-human spatialities  

摘要： The aim of this article is to stretch spatial theorising in the field of comparative education. Among the different spatial theoretical approaches that have been explored in educational research in the last 10 years, we review social topology, spatial-temporalities, and beyond-human spatialities and how they have been used in comparative education research. To illustrate the potential of these approaches we then use them to analyse recent technological changes, shifts in governance, the impacts of global crises and the complicated ways in which they are spatially related to education. Through our analysis, we argue that comparative education research would benefit from making space for spatial theorising in relation to time, materiality, and the beyond-human, not only to better understand the world, but also to consider how education is ethically linked to the existential challenges humanity is facing today.
