近年来,随着我国“一带一路”政策和非洲区域经济发展,中资企业在非洲公路建设项目日益增多,在保证工程质量的前提下,降低成本,获得外方业主、监理的认可是海外建设者努力的目标。该项研究以西非几内亚CMD项目中PK0~PK83基层级配碎石施工为背景,采用砂岩机制细集料代替部分石粉,通过技术数据论证,确定最佳掺配比例,并取得国际监理批准使用。砂岩机制细集料有着含泥量低,板结效果较好的特性,适量掺入一定程度能改善了基层级配碎石技术性能,在降低施工成本的同时,提高了路面基层质量,从而延长了公路本身的使用寿命。

目的构建老年2型糖尿病病人6个月内发生低血糖的风险预测模型。方法便利抽样选取2022年2—8月于南京医科大学附属老年医院门诊及住院的老年2型糖尿病病人277例,根据随访6个月内是否出现低血糖分为低血糖组(69例)和非低血糖组(208例)。采用LASSO回归和多因素Logistic回归分析确定影响因素,构建列线图预测模型并对模型进行评价。结果24.91%(69/277)的病人在6个月内发生低血糖。低血糖病史(OR=6.989,95%CI:3.671~13.844,P<0.001)是老年2型糖尿病病人6个月内发生低血糖的危险因素,而高MMSE得分(OR=0.890,95%CI:0.820~0.959,P=0.003)、TG≥1.7 mmol/L(OR=0.268,95%CI:0.083~0.708,P=0.014)是保护因素。构建的风险预测模型AUC为0.801(95%CI:0.742~0.860),灵敏度为0.841,特异度为0.673,准确度为71.48%。在内部验证中矫正后的AUC为0.783;Hosmer-Lemeshow拟合优度检验显示该模型具有良好的校准度(χ2=10.81,P=0.212);临床决策曲线分析(DCA)结果显示,模型的预测阈值为0.02~0.69时,病人的临床净收益水平最高。结论构建的低血糖风险预测模型具有较好的区分度、校准度和临床适用性,可为医护人员识别高风险人群并采取预防性干预提供依据。

目的探讨老年2型糖尿病病人体脂率与血糖波动的关系。方法收集188例老年2型糖尿病病人的体脂率和血糖值,以血糖标准差(SDBG)作为血糖波动指标,将病人分为血糖波动大组(SDBG≥2 mmol/L)和血糖波动小组(SDBG<2 mmol/L),比较2组间腰围、臀围、腰臀比、体脂率的差异。采用Spearman相关分析SDBG与腰围、臀围、腰臀比、体脂率的关系;应用二元Logstic回归分析老年2型糖尿病病人血糖波动的影响因素。结果与血糖波动小组比较,血糖波动大组病程更长,腰围、臀围、腰臀比、体脂率更小,差异有统计学意义(P<0.05)。相关性分析显示:SDBG与腰围、臀围、腰臀比、体脂率呈负相关(r分别为-0.225、-0.162、-0.166、-0.232,均P<0.05)。二元Logistic回归分析显示:调整了病程、腰臀比后,体脂率是血糖波动的独立影响因素(OR=0.946,95%CI:0.903~0.991,P=0.020)。结论老年2型糖尿病病人体脂率与血糖波动呈负相关,关注老年糖尿病病人血糖波动,应注意维持合理的体脂率。

Over the past 70 years, the semiconductor industry has undergone transformative changes,largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional(2D) materials like transition metal dichalcogenides(TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.
