目的探讨肺神经内分泌细胞(PNEC)和γ-氨基丁酸(GABA)在肺神经内分泌肿瘤(PNET)患者中的作用。方法收集2018年10月-2022年1月解放军总医院第八医学中心呼吸与危重症医学部胸外科收治的29例PNET患者的病理标本,采用HE染色观察形态学特征,免疫组织化学染色观察突触素(Syn)、嗜铬粒蛋白A(CgA)、CD56、Ki-67、CD86和CD163的表达水平,双抗体免疫荧光共染检测不同类型PNET中降钙素基因相关肽(CGRP)和谷氨酸脱羧酶(GAD)65/67的表达情况,并分析GAD65/67阳性PNEC与巨噬细胞极化的相关性。结果HE染色结果显示,4种类型的PNET组织均具有神经内分泌特征——玫瑰花样结构和器官嵌套或栅栏状图案,但各有差异;有丝分裂细胞占比由低到高为典型类癌(TC)、不典型类癌(AC)、大细胞神经内分泌癌(LCNEC)、小细胞肺癌(SCLC)。免疫组织化学染色结果显示,类癌(TC和AC)的Syn、CgA阳性表达率及Syn、CgA、CD56阳性程度均明显高于LCNEC和SCLC(P75%。类癌的PNEC数量明显高于LCNEC、SCLC和瘤旁组织(P0.05)。免疫荧光染色结果显示,95%的PNEC共表达GAD65/67;类癌GAD65/67阳性细胞数明显增多于LCNEC、SCLC和瘤旁组织(P0.05)。免疫组织化学染色结果还显示,瘤旁组织中CD86阳性M1巨噬细胞明显多于CD163阳性M2巨噬细胞(P<0.05);而在AC、LCNEC和SCLC中,M2巨噬细胞均明显多于M1巨噬细胞(P<0.01)。相关性分析显示,PNET中GAD65/67阳性PNEC细胞数与肿瘤间质中CD163阳性M2巨噬细胞数呈负相关(r=-0.6336,P=0.0174)。结论PNEC是肺组织中GABA的主要来源,在肺中发挥免疫调节作用,可能参与PNET的进展。

Liquid leakage of pipeline networks not only results in considerableresource wastage but also leads to environmental pollution and ecological *** response to this global issue, a bioinspired superhydrophobic thermoplastic polyurethane/carbon nanotubes/graphene nanosheets flexible strain sensor (TCGS) hasbeen developed using a combination of micro-extrusion compression molding andsurface modification for real-time wireless detection of liquid leakage. The TCGSutilizes the synergistic effects of Archimedean spiral crack arrays and micropores,which are inspired by the remarkable sensory capabilities of scorpions. This designachieves a sensitivity of 218.13 at a strain of 2%, which is an increase of 4300%. Additionally, it demonstrates exceptional durability bywithstanding over 5000 usage cycles. The robust superhydrophobicity of the TCGS significantly enhances sensitivity and stability indetecting small-scale liquid leakage, enabling precise monitoring of liquid leakage across a wide range of sizes, velocities, and compositionswhile issuing prompt alerts. This provides critical early warnings for both industrial pipelines and potential liquid leakage scenariosin everyday life. The development and utilization of bioinspired ultrasensitive flexible strain sensors offer an innovative and effectivesolution for the early wireless detection of liquid leakage.
