目的根据CT影像及肿瘤标志物结果,建立低分化腺癌预测模型,并进行内部验证。方法选择2023年在南京医科大学附属脑科医院胸外科行手术治疗的实性与部分实性肺结节患者,按照7∶3比例将患者随机分为训练集和验证集。收集患者CT特征,包括结节平均密度值、最大直径、胸膜牵拉征和支气管充气征,以及肿瘤标志物结果。依据术后病理结果,将患者分为低分化腺癌组和非低分化腺癌组。对训练集采用单因素分析和logistic回归分析,并以此建立预测模型,采用受试者工作特征(receiver operating characteristic,ROC)曲线评估模型区分度,校准曲线评估模型的一致性,绘制决策曲线评估该模型的临床价值,并在验证集中校验模型。结果共纳入299例患者,其中男103例、女196例,中位年龄57.00(51.00,67.25)岁;训练集211例,验证集88例。多因素分析显示癌胚抗原(CEA)值[OR=1.476,95%CI(1.184,1.983),P=0.002]、细胞角蛋白19片段抗原(CYFRA21-1)值[OR=1.388,95%CI(1.084,1.993),P=0.035]、肿瘤最大直径[OR=6.233,95%CI(1.069,15.415),P=0.017]、肿瘤平均密度[OR=1.083,95%CI(1.020,1.194),P=0.040]是实性与部分实性肺结节低分化腺癌的独立危险因素。基于此构建预测模型,ROC曲线下面积为0.896[95%CI(0.810,0.982)],最大约登指数对应截点值为0.103,灵敏度为0.750,特异度为0.936。Bootstrap法抽样1000次,校准曲线图预测概率与实际风险一致。决策曲线分析表明,在全预测概率下均有正收益,有较好临床价值。结论对于实性与部分实性肺结节患者,术前使用CT测量肿瘤平均密度值、最大直径,同时联合肿瘤标志物CEA、CYFRA21-1值可有效预测结节是否为低分化腺癌,以尽早予以干预。

Disassembly and recycling of E-waste creates a series of environmental problems. The selection of a technologically reliable, environmentally friendly, economically affordable and socially acceptable recycling technology for E-waste is a significant question. This study establishes a Monte-Carlo mathematical model of cost minimization, given the constraints of environmentally sound handling of the e-waste, in the context of Crystal Ball risk assessment and evaluation software. By following the streams of the different treatment processes, which consist of various technologies including disassembly, recycling and disposal, the econom-ics of various possibilities were identified and the optimal recycling technology proposed. The key factors of the proposed scenarios were determined by using sensitivity analysis. The results of this study show that, for discarded refrigerators, the operating life span plays the key role. The model supports maintenance and resale of the short lived refrigerators. For the longer lived refrigerators material recycling is recommended by the model. Sensitivity analysis shows that purchase cost, plastic sale price, condenser sale price and disassembly costs are the main effects. This study provides a significant technical support for policy making in E-waste management.
