目的:探讨食管癌(Esophageal Cancer,EC)患者E-钙黏蛋白(E-cadherin,E-cad)、细胞角蛋白14(Cytokeratin 14,CK14)、凋亡抑制蛋白Apollon(Inhibitor of Apoptosis Protein Apollon,IAP Apollon)表达及其与病理参数的相关性。方法:选取我院2018年1月至2020年1月期间收治的87例EC患者作为研究对象。分别取患者EC组织和癌旁组织。采用免疫组化法检测E-cad、CK14、Apollon在EC组织和癌旁组织中的表达。分析比较不同病理学参数EC组织中E-cad、CK14、Apollon的表达情况。分析EC组织中E-cad、CK14、Apollon表达与临床病理学参数相关性。探讨E-cad、CK14、Apollon表达与EC患者预后关系。结果:EC组织中CK14、Apollon阳性表达率显著高于癌旁组织,Ⅰ-Ⅱ期显著低于Ⅲ-Ⅳ期,高分化<中分化<低分化,无淋巴结转移显著低于有淋巴结转移(P<0.05)。EC组织中E-cad阳性表达率显著低于癌旁组织,Ⅰ-Ⅱ期显著高于Ⅲ-Ⅳ期,高分化>中分化>低分化,无淋巴结转移显著高于有淋巴结转移(P<0.05)。EC组织中E-cad阳性表达率与肿瘤转移(Tumor Node Metastasis,TNM)分期、淋巴结转移呈负相关,与分化程度呈正相关。CK14、Apollon阳性表达率与TNM分期、淋巴结转移呈正相关,与分化程度呈负相关(P<0.05)。E-cad阳性EC患者3年生存率高于E-cad阴性患者,CK14阳性、Apollon阳性EC患者3年生存率分别低于CK14阴性、Apollon阴性患者(P<0.05)。结论:EC患者癌组织中CK14、Apollon呈现高表达,E-cad呈现低表达,与EC发生、发展、分化程度、TNM分期、淋巴转移及预后有紧密联系。
Spectral-broadening of the APOLLON PW-class laser pulses using a thin-film compression technique within the longfocal-area interaction chamber of the APOLLON laser facility is reported,demonstrating the delivery of the full energy pulse to the target interaction area.The laser pulse at 7 J passing through large aperture,thin glass wafers is spectrally broadened to a bandwidth that is compatible with a 15-fs pulse,indicating also the possibility to achieve sub-10-fs pulses using 14 J.Placing the post-compressor near the interaction makes for an economical method to produce the shortest pulses by limiting the need for high damage,broadband optics close to the final target rather than throughout the entire laser transport system.
We present the results of the first commissioning phase of the short-focal-length area of the Apollon laser facility(located in Saclay,France),which was performed with the first available laser beam(F2),scaled to a nominal power of 1 PW.Under the conditions that were tested,this beam delivered on-target pulses of 10 J average energy and 24 fs duration.Several diagnostics were fielded to assess the performance of the facility.The on-target focal spot and its spatial stability,the temporal intensity profile prior to the main pulse,and the resulting density gradient formed at the irradiated side of solid targets have been thoroughly characterized,with the goal of helping users design future experiments.Emissions of energetic electrons,ions,and electromagnetic radiation were recorded,showing good laser-to-target coupling efficiency and an overall performance comparable to that of similar international facilities.This will be followed in 2022 by a further commissioning stage at the multipetawatt level.
