目的分析腹腔镜下根治性前列腺切除术后切缘阳性的影响因素。方法回顾性分析2018年6月-2022年5月于青岛大学附属医院泌尿外科接受了腹腔镜下根治性前列腺切除术的238例前列腺癌患者的临床资料。根据术后病理检查结果,将纳入的患者分为切缘阳性组与切缘阴性组,比较两组患者的一般临床资料[年龄、体质量指数(BMI)、前列腺体积、手术方式]、术前血清总前列腺特异性抗原(TPSA)衍生指标[TPSA、游离前列腺特异性抗原(FPSA)/TPSA、前列腺特异性抗原密度(PSAD)]、穿刺因素(术前穿刺阳性针数比、术前穿刺Gleason评分)、术前MRI影像学特征[术前临床分期、前列腺影像报告和数据系统(PI-RADS)评分、mpMRI肿瘤异常信号位置、mpMRI肿瘤异常信号部位、mpMRI膜部尿道长度、mpMRI最大肿瘤异常信号横径],通过多因素逻辑回归法分析前列腺癌术后切缘阳性率的影响因素。结果两组患者的血清TPSA、血清PSAD、术前穿刺Gleason评分、术前穿刺阳性针数比、术前临床分期、mpMRI肿瘤异常信号位置比较差异均有显著性(χ2=22.539~62.367,P<0.05)。多因素分析表明,术前临床分期(OR=3.574,95%CI=1.975~9.298,P<0.05)、术前穿刺阳性针数比(OR=5.043,95%CI=2.496~10.189,P<0.05)是切缘阳性的独立影响因素。结论术前临床分期和术前穿刺阳性针数比是前列腺癌患者术后切缘阳性的独立影响因素,本研究为临床医生术前通过mpMRI的影像学特征预测患者术后切缘阳性提供了参考依据。

Artificial empathy in service encounters: Engaging customers...

Data-driven evacuation and rescue traffic optimization with rescue contraflow control

第十八届（2023）中国管理学年会暨“一带一路”十周年研讨会

作者： xuecheng yang Jing Guo Beijing University of Posts and Telecommunications

AI chatbots have been widely used in online service encounters. As service providers, AI chatbots with empathic characteristics can better enhance customer affective experience and engagement, and facilitate affective co-creation experience(ACE) in human-AI interaction. Thus, focusing on how artificial empathy(AE) influence customer service engagement behaviors(SEB, including exploration and coordination), the contextual experimental method was used to analyze 61 subjects to determine the conversational corpus, and the questionnaire method was used to analyze 381 subjects for the model. The results show that:(1) after controlling for gender, age, attitude, and other variables, artificial empathy has a significant positive effect on engagement behaviors;(2) affective experience mediates the relationship between artificial empathy and engagement behaviors;(3) technology affinity moderates both the direct effect of artificial empathy on engagement behaviors and the indirect effect through affective experience. The research findings enrich the affective experience co-creation framework from the perspective of human-AI service interaction and develop social contagion theory and service dominance logic, and provide implications for enterprises to adjust marketing strategies and improve marketing effectiveness.
