BACKGROUND Anesthetic drugs used in labor analgesia also paralyze the bladder muscle by blocking the sacral plexus,thereby affecting maternal postpartum spontaneous urination and increasing the risk of postpartum urinary retention(PUR).AIM To analyze the effect of percutaneous electrical stimulation at the Baliao point combined with biofeedback therapy for PUR *** We selected 182 pregnant women who received labor analgesia in obstetrics between June 2022 and December *** were divided into the combined therapy group(transcutaneous electrical stimulation of the Baliao point combined with biofeedback therapy)and the control group(biofeedback therapy alone).The first spontaneous urination time,first postpartum urine volume,bladder residual urine volume,postpartum hemorrhage volume,pre-urination waiting time,PUR incidence,adverse reactions,and the intervention’s clinical efficacy were compared between the two *** The first spontaneous urination time after delivery was more delayed(2.92±1.04 h vs 3.61±1.13 h,P<0.001),with fewer initial postpartum urine(163.54±24.67 mL vs 143.72±23.95 mL,P<0.001),more residual bladder urine(54.81±10.78 mL vs 65.25±13.52 mL,P<0.001),more postpartum bleeding(323.15±46.95 mL vs 348.12±45.03 mL,P=0.001),and longer waiting time for urination(0.94±0.31 min vs 1.29±0.42 min,P<0.001),in the control group than in the combined therapy *** control group also had higher PUR incidence(4.65%vs 15.85%,P=0.016).Both groups had no adverse reactions,but the clinical total efficacy rate of the intervention was significantly higher in the combined therapy group than in the control group(95.35%vs 84.15%,P=0.016).CONCLUSION Percutaneous electrical stimulation of the Baliao point combined with biofeedback can significantly promote postpartum micturition of parturients with labor analgesia,thereby effectively preventing PUR occurrence.

随着全球能源需求不断增长,传统矿石燃料面临着储量有限和环境污染等问题.核能因其清洁绿色的特性,在推动绿色发展中扮演着日益重要的角色.铀作为核能的核心要素,其资源需求巨大.虽然海洋中蕴藏着丰富的铀资源,但其浓度极低,因此如何高效地从海水中提取铀成为当前亟需解决的挑战.近几十年来,尽管海水提铀材料的研发已取得可观成效,但仍存在提铀材料吸附容量较低和实际应用难等问题.随着研究的不断深入,众多新兴材料已经展现出突破性的吸附容量,并具备抗生物污损等协同功能,用于改善其实际应用效果.因此,现将近5年来的海水提铀材料新进展进行综述,根据吸附法、电化学法和多种方法结合这三种方法分类阐述其开发策略及提铀性能,最后对未来海水提铀的研究方向进行了展望,旨在为未来海水提铀新材料的开发提供参考价值.

月球冷却过程中积累的热应力是影响月球内部力学环境的重要因素之一。使用三维黏弹性有限元模型计算月球热应力的积累过程,并通过对比实验分析黏性参数对热应力大小的影响。计算结果表明月幔深部和浅部的热应力状态存在截然的分界。浅部热应力以切向挤压为主,挤压应力最大值出现在月壳底部;深部径向和切向正应力的大小主要受浅部径向正应力的控制,径向和切向热应力均为拉张,但由于黏性松弛差应力的积累和松弛动态平衡,而处于接近“静水压”状态。假设月球岩石圈的黏度大于10^(28)Pa·s,则现今月壳和浅部月幔水平挤压热应力可以达到数百MPa,而月幔深部的拉张热应力可达到数十~100 MPa。因此,震源深度较浅的浅源月震可以用热应力来解释。而深源月震成因仍是一个困难的问题,推测深部月幔的拉张热应力为孔隙结构的发育提供了条件,而月幔底部的熔融层提供了高压孔隙流体,从而降低了深部月幔介质的破裂强度。

文章基于多学科交叉研究,提出了旅游疗愈理论,构建了由“天”“地”“人”三大系统及其构成要素,以及“天人地交互效应”作用机制组成的旅游疗愈理论模型,阐述了各构成要素之间的内在生成机制,以及对人体健康提升的作用路径,为进一步了解“天”“地”与“人”的健康互动关系提供了理论支撑。受旅游疗愈主体“人”的健康需求驱动,会产生此类“应时而宜”的康复性旅游流动,让人“远离”惯常环境中的“烦”与“身心不适”,置身于“迷人”的环境中,会产生更多的非定向注意力和健康效益,进而提升生命质量,实现健康的体魄在诗与远方遨游。该研究进一步发掘了旅游的社会价值和社会贡献,使更多符合游客健康需求的产品供给、资源利用、空间开发成为可能,从而促进旅游学与生命科学的跨学科理论实践。

近年来,数字游民的概念和模式在乡村振兴领域颇受欢迎,但舶来的数字游民本质上是一个互联网产品,乡村在其框架中更多是作为文化和生态的空间消费场景而出现的,青年与乡村很难有深刻的互动。但是,在该概念旅行的过程中,一些数字游民基地也开始了本土化的调试。通过对这些新实践的田野观察,研究发现:中国乡村的数字游民基地建设,不再将互联网逻辑作为主导性逻辑,而是以县域高质量发展中的问题为导向,结合乡村振兴战略,致力于解决青年入乡的最后一公里问题,在创造青年和乡村见面机会的同时,探索性地发展出兼具城乡要素的融合式的生产生活新方式,以青年流动为方法,破解城乡之间资源要素双向流动的难题。聚焦流动,也是在理论层面重返传播。
