液体深度除湿是实现低湿度行业低碳转型的一种有效途径。目前,具有深度除湿潜力(极低蒸气压、非结晶和无腐蚀)的离子液体是传统盐溶液的理想替代。本研究搭建了离子液体深度除湿实验平台,并分析了不同运行工况下的除湿性能。结果表明:降膜/鼓泡吸收方式均能实现较高的深度除湿效果,最低出风含湿量可降至2.0 g/kg(da)以下。同时,对于进口含湿量为3.3 g/kg(da)的低湿工况,降膜装置的除湿效率仅为40%左右。然而,鼓泡装置的除湿效率可达到81%,有效开发了离子液体的深度除湿潜力。此外,总结了两种吸收方式的先进性与适用性,为离子液体深度除湿技术的应用提供指导。

小麦胚芽作为小麦面粉加工过程中产生的副产品,资源极为丰富,但一直以来未能得到充分合理的利用.本研究以课题组前期获得的麦胚活性肽ADWGGPLPH(ADW)为对象,以自然增龄的SD大鼠作为肝脏老化损伤的动物模型,9月龄大鼠作为对照,用麦胚源活性肽持续灌胃干预至21月龄,研究麦胚源活性肽对自然增龄大鼠肝脏老化损伤的影响,并结合H2O2诱导衰老HepG2细胞模型初步探明其分子机制.结果表明,麦胚源活性肽ADW能够增加大鼠血清及肝脏中SOD,T-AOC,GSH-Px,CAT等抗氧化酶活性,同时降低MDA水平,改善大鼠肝脏中氧化应激水平;降低血清及肝脏中IL-6,IL-1β,MMP3,TNF-α水平,并且增加抗炎因子IL-10分泌,改善增龄大鼠肝脏中炎症环境;麦胚源活性肽干预后肝脏结构明显好转、脂肪空泡减少、细胞排列整齐,ALT以AST水平均显著下降.麦胚源活性肽能够有效地改善老化肝脏中细胞的结构及生长状态异常,减少增龄过程中肝脏质量损失,降低了衰老标志蛋白P53和P21的表达量,减轻肝脏老化损伤程度并减缓了肝脏的老化进程.通过加入抑制剂、激活剂、siRNA等手段,初步阐明麦胚源活性肽能够通过激活AMPK/Sirt1信号通路以调控衰老相关进程.本研究对于开发健康老龄化膳食结构以及麦胚资源的精深利用具有十分重大的意义.

面对日益严峻的人口少子化问题,日本有计划地在中小学家庭科课程中开展以遏止少子化为目的的价值观教育。从21世纪初开始,日本政府通过宏观规划、政策保障和课标融入等方式为家庭科课程设计了明确的家庭观、生育观和两性观教育内容,并通过家政技能实践、“男女共学”和校社协同联动等方式深化青少年对组建家庭和养育后代的价值认同。近年来,中国“低生育率”问题愈加凸显,亟须有针对性地通过学校课程开展价值观教育,树立倡导积极的婚育观念,发挥好教育促进人口可持续发展的重要作用。

Objectives: This study aimed to determine whether errors in vascular measurements would affect device selection in endovascular aortic repair (EVAR) by comparing measurements obtained using non-contrast computed tomography (NCT) with those obtained using contrast-enhanced CT (CECT). Materials and Methods: This single-center, retrospective study included 25 patients who underwent EVAR for abdominal aortic aneurysm at our institution. A 1-mm horizontal cross-sectional slice of NCT and CECT from each patient was retrospectively reviewed. The area from the abdominal aorta to the common iliac artery was divided into four zones. A centerline was created using the NCT by manually plotting the center points. Subsequently, the centerlines were automatically extracted and manually corrected during the arterial phase of CECT. The diameter and length of each zone were measured for each modality. The mean diameters and lengths of the target vessels were compared between NCT and CECT. Results: The measurements obtained using both methods were reproducible and demonstrated good agreement. The mean differences in vessel length and diameter measurements for each segment between NCT and CECT were not statistically significant, indicating good consistency. Conclusion: NCT may be useful for preoperative EVAR evaluation in patients with renal dysfunction or allergies to contrast agents.
