目的探讨行达芬奇机器人辅助腹腔镜胰腺癌根治手术的患者发生术后意外低体温(UPH)的危险因素,构建风险预测模型并评价其预测效能。方法选取2020年12月至2021年12月在海军军医大学(第二军医大学)第一附属医院接受达芬奇机器人辅助腹腔镜胰腺癌根治手术的患者作为研究对象,根据UPH的发生情况将患者分为UPH组和非UPH组。比较两组患者的一般资料(年龄、性别、美国麻醉医师学会分级、BMI、术前血红蛋白、术前白蛋白、基础体温)、手术资料(手术方式、神经阻滞类型、麻醉时间、手术时间、人工气腹建立时间、术后体温、术后并发症、院内转归)、围手术期液体管理资料(晶体液、胶体液、红细胞悬液、新鲜冰冻血浆、失血量、尿量)。采用logistic回归方法构建UPH预测模型,绘制ROC曲线和决策曲线评价模型预测UPH的效能,并建立列线图模型。结果共纳入患者246例,其中117例(47.6%)发生UPH。两组患者的BMI(P=0.047)、术前血浆白蛋白水平(P=0.038)、术后肺部并发症(PPC,P=0.039)、非肺部术后感染(NPPI,P=0.018)、总住院时间(P=0.001)、手术方式(P=0.042)、手术时间(P=0.038)、术中人工气腹建立时间(P=0.004)、神经阻滞类型(P=0.004)、术后体温(P<0.001)比较差异均有统计学意义。logistic回归分析结果显示达芬奇机器人辅助术式(OR=9.369,95%CI 2.528~34.717,P=0.001)、BMI(OR=0.787,95%CI 0.687~0.902,P=0.001)、手术时间(OR=0.040,95%CI 0.009~0.183,P<0.001)、人工气腹建立时间(OR=15.608,95%CI 3.814~63.870,P<0.001)、输液速率(OR=0.808,95%CI 0.706~0.924,P=0.002)、输液总量(OR=3.431,95%CI 1.480~7.956,P=0.004)及神经阻滞类型(OR=0.240,95%CI 0.131~0.443,P<0.001)与UPH的发生具有独立相关性。ROC曲线的AUC值为0.739,预测发生UPH的灵敏度为0.778,特异度为0.628。决策曲线分析结果表明预测模型具有较好的临床净收益。结论BMI低、输液速率慢、输液总量大、椎旁神经阻滞、胰十二指肠切除术、手术时间长、人工气腹建立时间长是达芬奇机器人辅助腹腔镜胰腺癌根治手术患者发生UPH的危险因素,根据上述因素构建的风险预测模型效果较好。

农户是参与社会公益的有生力量,数字技术的普及进一步激发了农户公益参与热情,但相关理论机制仍然是模糊的。利用上海财经大学2019年“千村调查”数据进行论证可以发现,数字技术使用显著促进了农户参与公益活动。数字技术使用通过提高农户收入、促进农户社会互动和提升农户同理心水平推动农户参与公益活动,数字技术影响农户公益参与存在三重效应,即收入溢出效应、社会互动效应和同理心效应。村庄人力资本水平、村庄集体行动频率和村务信息透明度越高,数字技术使用对农户公益参与的促进作用越强。利用数字技术激发农民群体的公益潜力,提高广大农户对慈善公益的参与度,有利于汇聚更广泛的公益力量,支持我国社会公益事业高质量发展。

把马克思主义同中华优秀传统文化相结合是在探索中国特色社会主义道路过程中取得的规律性认识。“彼此契合”是两者相结合的前提,其内在理论内涵包含五个方面,即“相似”“相通”“相融”“相合”和“相需”。马克思主义与中华优秀传统文化契合性的运行机理通过“静态系统”与“动态系统”、“表”与“里”的辩证统一共同推动了二者的协调共生和发展促进。马克思主义与中华优秀传统文化契合性的价值旨归在于其既同“第二个结合”的发展进程密切相关,同时又突出了“第二个结合”的关键所在,实现了两者的协同共进。

We present an analytical analysis of the spatial resolution of quantum ghost imaging implemented by entangled photons from a general, spontaneously parametric, down-conversion process. We find that the resolution is affected by both the pump beam waist and the nonlinear crystal length. Hence, we determined a method to improve the resolution for a certain imaging setup. It should be noted that the resolution is not uniquely related to the degree of entanglement of the photon pair since the resolution can be optimized for a certain degree of entanglement. For certain types of Einstein-Podolsky-Rosen(EPR) states——namely the momentum-correlated or momentum-positively correlated states——the resolution exhibits a simpler relationship with the pump beam waist and crystal length. Further, a vivid numerical simulation of ghost imaging is presented for different types of EPR states,which supports our analysis. This work discusses applicable references to the applications of quantum ghost imaging.
