We combine communication theory and behavioral models and using a sample of USA individuals (N = 7225) based on the American Trends Panel to predict variations in pro-environmental behavior. We show that social networks rather than information are more effective in predicting pro-environmental behavior. Moreover, a pro-environmental lifestyle as well as climate change experiences at the community level increase the likelihood for pro-environmental participation. However, affordances related to socioeconomic variations generate variations to pro-environmental civic participation. We conclude that in order to capture the depth of pro-environmental civic participation, it is necessary to theoretically and empirically bridge between private and public expressions of pro-environmental awareness.展开更多
目的评估胃泌素释放肽前体(Pro-gastrin-releasing peptide,PRO-GRP)、神经元特异性烯醇酶(Neuron-specific enolase,NSE)、癌胚抗原(Carcinoembryonic antigen,CEA)、细胞角蛋白-19片段21-1(Cytokeratin-19 fragment 21-1,CYFRA21-1)...目的评估胃泌素释放肽前体(Pro-gastrin-releasing peptide,PRO-GRP)、神经元特异性烯醇酶(Neuron-specific enolase,NSE)、癌胚抗原(Carcinoembryonic antigen,CEA)、细胞角蛋白-19片段21-1(Cytokeratin-19 fragment 21-1,CYFRA21-1)及鳞状细胞癌抗原(Squamous cell carcinoma antigen,SCC)血清肿瘤标志物在肺癌早期诊断中的价值,并探究它们作为诊断指标的组合效应。方法选择2020年1月至2022年10月期间收治的60例肺癌患者作为阳性组,同时纳入90例良性肺疾病患者作为阴性组。所有患者均接受血清肿瘤标志物检测,检测方法为免疫化学发光法,检测指标包括:PRO-GRP、NSE、CEA、CYFRA21-1及SCC。比较两组患者血清标志物的含量,并分析其阴阳表达情况。利用二元多因素回归分析,将这些标志物作为自变量,是否诊断为肺癌阳性作为因变量,探究其对肺癌诊断的独立危险因素。应用ROC曲线分析评估单独及联合检测这些标志物对肺癌的诊断价值,统计ROC曲线下面积(Area Under the Curve,AUC)、敏感度和特异度。结果阳性组患者的血清PRO-GRP、NSE、CEA、CYFRA21-1、SCC含量均显著高于阴性组(P<0.05)。单因素分析结果显示,这些标志物均为影响肺癌诊断结果的可疑因素(P<0.05)。多因素分析结果表明,它们在肺癌诊断为阳性时均为独立的危险因素(P<0.05)。ROC曲线分析显示,PRO-GRP、NSE、CEA、CYFRA21-1、SCC的单独及联合检测在肺癌诊断中具有统计学意义(P<0.05)。联合预测因子的AUC、敏感度和特异度均高于单独检测指标。结论PRO-GRP、NSE、CEA、CYFRA21-1及SCC血清肿瘤标志物在肺癌早期诊断中具有重要的诊断价值。联合检测这可以提高肺癌早期诊断的准确性,成为有力的肺癌筛查和早期诊断工具。展开更多
