To the Editor : Pancreatic hamartoma is an extremely rare and benign disease and accounts for less than 1% of all pancreatic tumors [1]. Pancreatic lipomatous hamartoma(PLH), a distinct variant of pancreatic hamartoma, is always easily misdiagnosed as other pancreatic tumors with lipomatous components, including pancreatic lipoma, liposarcoma, teratoma and malignant tumors with fatty degeneration. Here, we report a case of laparoscopic enucleation for the pancreatic head lipomatous hamartoma and provide new treatment strategies for surgeons who encounter similar diseases in the future.

Infiltration by monocytes of the central nervous system and its role in multiple sclerosis: reflections on therapeutic strategies

Neural Regeneration Research 2025年第3期20卷 779-793页

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

【目的】基于烟粉虱Bemisia tabaci转录组数据,系统分析了烟粉虱解毒代谢酶基因在噻虫嗪抗性品系中的表达模式,探讨了这些基因在烟粉虱不同发育阶段差异表达的生物学意义。【方法】分别收集室内长期饲养的烟粉虱噻虫嗪抗性和敏感品系的卵、4龄若虫和刚羽化1 d的雌成虫,在烟粉虱转录组数据库中挑选8 394条解毒代谢相关基因设计探针,通过探针杂交,得到烟粉虱噻虫嗪抗性品系表达谱芯片,比较了这些基因在抗性烟粉虱3个不同发育阶段的表达情况。并随机挑选了9个基因,在抗感品系间3个不同发育阶段进行了荧光定量PCR验证。【结果】在抗性烟粉虱的卵和4龄若虫发育阶段,共有3 424个差异表达基因,其中489个是编码3类解毒代谢酶(羧酸酯酶、谷胱甘肽-S-转移酶和细胞色素P450多功能氧化酶)的基因;有14个基因在4龄若虫发育阶段过量表达,其中10个为P450基因,4个为GST家族基因。在抗性烟粉虱的4龄若虫和雌成虫发育阶段,总共有1 273个差异表达基因,193个为3类解毒代谢酶家族的基因,其中有9个P450家族基因在雌成虫期的表达量超过4龄若虫期的10倍。此外,表达谱芯片分析还筛选到了一些候选抗性基因。qRT-PCR验证显示在这些候选基因中,与敏感品系相比,9个基因在抗性烟粉虱的3个不同发育阶段表达上调,其中GST基因家族的p_06027和P450基因p_06013在抗性品系的卵和4龄若虫中过量表达;p_05885和p_07806和编码CYP6家族蛋白的p_00988在抗性品系的4龄若虫期的表达量上调;p_05916和p_00478在抗性品系卵和4龄若虫期表达量很低,而在成虫期过量表达;而p_00059和p_00428在抗性品系雌成虫发育阶段表达量显著上调,其中编码CYP4C1的p_00059的差异表达倍数在雌成虫期约为15.15倍。【结论】表达谱芯片分析结果提示,CYP6和CYP4C1基因的过量表达可能会是烟粉虱抗性产生的机制之一。解毒代谢酶基因在烟粉虱不同发育阶段的特异性表达,可能与其在抵御杀虫剂胁迫时体内能量的分布及有效利用率有关,也可能是害虫在环境选择压下的一种适应机制。

Synergistic effect of bonding heterogeneity and phonon localization in introducing excellent thermoelectric properties in layered heteroanionic NdZnSbO material

引用

Journal of Energy Chemistry 2025年第01期 259-272页

作者： da wan Shuwei Tang Shulin Bai Xiaodong Li Peng Ai wanrong Guo Tuo Zheng College of Materials Science and Engineering Liaoning Technical University Faculty of Chemistry Northeast Normal University

Layered rare-earth metal oxides, harnessing the dual properties of oxides and two-dimensional layered materials, exhibit remarkable thermal stability and quantum confinement effects. Therefore, this work adopts the first-principles calculation combined with the Boltzmann transport theory to predict the thermoelectric properties of NdZnSbO compound. The coexistence of weak interlayer van der Waals interactions, robust intralayer ionic bonding, and partial covalent bonding leads to remarkable bonding heterogeneity, which engenders pronounced phonon scattering and imposes constraints on thermal transport along the out-of-plane direction. The weakened chemical bonds induced by the antibonding states, together with the rattling-like behavior of the Zn atom, culminate in the profound anharmonicity in the layered NdZnSbO compound. The weakening bond and heavy element contribute to the softness of phonon modes, which significantly diminishes the phonon group velocity. The redistribution-dominated four-phonon scattering process spans a large optical gap, which effectively reduces the lattice thermal conductivity. The NdZnSbO compound exhibits direct semiconductor characteristic with a bandgap of 0.73 e V by adopting the Heyd-Scuseria-Ernzerhof(HSE06) functional in combination with spin–orbit coupling(SOC) effect. The multi-valley feature of NdZnSbO compound augur favorably for band degeneracy, thus amplifying the power factor. Consequently, an optimal figure-of-merit(ZT) of 3.40 at 900 K is achieved for the n-type NdZnSbO compound. The present study delves deeply insights into the origins for the low thermal conductivity of NdZnSbO compound and proposes an optimization scheme to enhance overall thermoelectric performance.
