目的探讨鳞状细胞癌抗原(SCC-Ag)、癌胚抗原(CEA)及糖类抗原-125(CA125)联合检测对早期宫颈癌的诊断效能。方法选取2023年1月~2023年12月我院妇科收治的宫颈上皮内瘤变(CIN)患者30例设为A组,宫颈癌患者60例(鳞腺癌10例,鳞癌35例,腺癌15例)设为B组,另选取同期健康体检者30例设为对照组。抽取所有受检者空腹静脉血,经化学发光法检测三组的SCC-Ag、CEA、CA125水平。分别对三组以及B组三种病理类型宫颈癌患者的血清SCC-Ag、CEA、CA125水平进行对比,并统计SCC-Ag、CEA、CA125单独检测及联合检测的诊断效能。结果B组的血清SCC-Ag、CEA、CA125水平均高于A组和对照组(P0.05)。结论血清SCC-Ag、CEA、CA125均对宫颈癌的诊断和预测具有一定的价值,且三种指标联合检测的灵敏度和准确度更高,可为宫颈癌的组织分期提供有利的依据,有利于后期开展治疗。

It is widely recognized that the development of ZABs is impeded by the kinetic bottleneck of oxygen evolution reaction(OER)and oxygen reduction reaction(ORR).The application of conformational entropy strategy to oxides often involves introducing multiple elements with different properties,thereby providing outstanding bifunctional catalytic activity for OER/***,the possible underlying catalytic pathways and potential interactions between various components are still poorly *** paper presents an excellent medium-entropy perovskite oxide,Sr(FeCoNiMo)_(1/4)O_(3−δ)(lower overpotential of 301 mV at 10 mA cm^(−2)).Zinc-air batteries employing it as a cathode catalyst demonstrate excellent round-trip efficiency(62%).By combining theoretical calculation with experiments,we aim to establish the link between the electronic structure of perovskite oxides with different elemental compositions and their OER *** reveals that the conformational entropy strategy can simultaneously shift the O 2p-band center and metal d-band center of perovskite oxide towards the vicinity of the Fermi energy level,thereby triggering a more favorable lattice oxygen-participated mechanism(LOM)during the OER *** outcomes of this work provide crucial insights into the role of conformational entropy strategies in oxygen catalysis and offer potential avenues for constructing efficient and stable electrocatalysts.
