白术是一种著名中药材,其品质与其种植产地密切关联,迫切需要寻找一种能快速对白术进行品质鉴定和产地溯源的方法。白术含有多种内源荧光物质,可为三维荧光技术鉴定白术的产地提供依据。首先使用交替三线性分解(ATLD)对白术三维荧光光谱进行表征,再将三维荧光光谱与偏最小二乘判别分析(PLS-DA)和k最邻近法(kNN)两种模式识别方法相结合对白术样品进行产地溯源。结果表明,PLS-DA和kNN各自建立的分类模型能有效对三大白术产区(安徽、湖南和浙江)的样本进行区分,对预测集中白术道地药材浙江白术的分类准确率(CCR)分别高达80%和90%。所建立方法为白术的产地溯源提供一种新颖、快速的解决方案,有利于维护白术市场的秩序,利于其产业发展。

Hepatobiliary & Pancreatic Diseases International 2024年第4期23卷 385-392页

Background: Obesity is a common public health issue and is currently deemed a disease. Research has shown that the risk of gallstones in individuals with obesity is elevated. This study aimed to explore the bile proteomics differences between cholelithiasis patients with obesity and normal body weight. Methods: Bile samples from 20 patients(10 with obesity and 10 with normal body weight) who underwent laparoscopic cholecystectomy at our center were subjected to tandem mass tag labeling(TMT) and liquid chromatography-tandem mass spectrometry(LC-MS/MS), followed by further bioinformatic analysis. Results: Among the differentially expressed proteins, 23 were upregulated and 67 were downregulated. Bioinformatic analysis indicated that these differentially expressed proteins were mainly involved in cell development, inflammatory responses, glycerolipid metabolic processes, and protein activation cascades. In addition, the activity of the peroxisome proliferator-activated receptor(PPAR, a subfamily of nuclear receptors) signaling pathway was decreased in the Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis. Two downregulated proteins in the PPAR signaling pathway, APO A-Ⅰ and APO A-Ⅱ, were confirmed using enzyme-linked immunosorbent assay. Conclusions: The PPAR signaling pathway may play a crucial role in the development of cholelithiasis among patients with obesity. Furthermore, biliary proteomics profiling of gallstones patients with obesity is revealed, providing a reference for future research.

铁电存储器以其优良的特性如低功耗、高耐久性和非挥发存储等而成为人们的关注点。由于要处理海量资料,必须要有高密度的内存整合,因此存储介质往往很薄。然而,在膜层减薄的情况下,传统钙钛矿材料的铁电性能将急剧下降,这对高密度集成的应用带来了严重的困难。研究表明,正交相的氧化铪具有铁电性,不但与CMOS工艺兼容,而且其铁电性在超薄膜厚下仍然保持优良,为实现大规模生产奠定了基础。但是,它存在唤醒效应、印记效应及可靠性不足等问题。调控相结构和氧空位状态是提高铁电性能的关键。本文将从元素掺杂、应力影响、氧空位调控等多方面介绍铪基薄膜铁电存储器改性的研究。
