国土开发和城乡融合已成为中国全面推进乡村振兴的重要途径,日本在相关领域丰富的政策及实践经验值得研究借鉴。本文考察日本乡村振兴的经济社会背景和法律规划变迁,梳理国土开发和城乡融合的政策和实践,总结其乡村振兴实现机制及对中国的启示。研究表明:第二次世界大战以后日本城乡关系由竞争转向融合,农村生态环保、文化交流、观光休闲等功能日益凸显。经过几十年探索,日本形成了以国土开发与城乡融合为两翼、从要素流动和空间拓展多维度发力的乡村振兴推进机制。主要经验包括经济增长奠定坚实基础、较为完备的法律体系、政府主导规划和支持措施、农村开发政策导向实现从外来到内生的转变、有重点地平衡区域发展、信息技术加速价值开发和城乡要素对流。出现的问题包括早期国土开发过度依赖中央主导型投资、缺乏独立的乡村振兴规划、地方中央规划的协调性差。基于较为成熟的经济发展阶段和国家治理体系,中国也形成了诸多有效的乡村振兴政策和实践模式。日本经验的有益启示包括完善国土规划体系、加快专业立法、创新经营与乡村治理模式、畅通城乡信息对流。

本文研究了三元Fe_(73)B_(22)Nb_5合金快速凝固过程中的组织演变规律,系统分析了凝固组织与合金微观力学性能以及室温磁学性能的关联机制.实验测定出合金固相线温度为1410 K,液相线温度为1525 K.在近平衡凝固条件下,初生Fe_(2)B相率先析出,剩余液相形成(FeNbB+αFe+Fe_(2)B)三元共晶.自由落体过程中合金液滴的过冷度随其直径的减小呈指数关系单调递增,最大过冷度可达352 K (0.23T_L).实验表明,基于过冷度对相组成的强烈影响,可以实现对合金微观力学性能和磁学性能的调控.随着过冷度的增大,初生Fe_(2)B相的生长被抑制,共晶组织体积分数逐渐增加.三元共晶中的FeNbB相对合金的微观力学性能有着显著的强化作用,其硬度为15.1 GPa,杨氏模量为170.7 GPa.深过冷条件下,液态合金快速凝固全部形成非规则三元共晶组织.溶质截留效应使得Nb元素分布更为均匀,FeNbB相体积分数明显增大,合金硬度最高可达1197 HV,矫顽力则由79 Oe锐减至54 Oe.

人乳头瘤病毒(human papillomavirus,HPV)所致感染是女性常见的性传播感染,低危型HPV感染可导致尖锐湿疣,高危型HPV持续感染可引起子宫颈癌前病变及子宫颈癌等疾病,严重威胁女性健康。近年来,我国HPV感染率及子宫颈癌发病率逐年升高,并呈年轻化趋势,因此应积极预防HPV感染以降低子宫颈癌以及其他HPV相关疾病及肿瘤的风险。针对HPV感染所致疾病的预防措施包括:(1)以健康教育及HPV疫苗接种为主要措施的一级预防。(2)以定期子宫颈癌筛查及癌前病变的早诊早治为主要措施的二级预防。(3)对子宫颈浸润癌进行诊治的三级预防。目前大量数据证明了HPV疫苗在降低HPV感染所致疾病发病率方面的作用,而对于适龄女性开展适宜的子宫颈癌筛查并及时干预也能够降低子宫颈癌的发生风险和死亡率,建议将适龄女性的HPV疫苗接种及定期子宫颈癌筛查结合起来,最大限度降低HPV感染相关疾病风险,尽早实现世界卫生组织(WHO)消除子宫颈癌的宏伟目标。

康养旅居是一种提升生活质量和生命质量的生活方式,是在中国时代特色背景下休闲度假产业与大健康产业深度融合的产物。然而,康养旅居对个体身心健康有何影响以及如何影响的机制尚未厘清。文章借鉴节奏分析理论,从单向度过程和循环过程两个时空尺度出发,探索旅居者生活节奏变化下康养旅居对其身心健康的影响机制。研究发现:1)从单次康养旅居的单向度过程来看,旅居者经历了日常节奏化-节奏中辍-节奏调整-节奏嵌入-节奏持存的节奏演进过程,康养旅居者节奏变化过程本身具有疗愈功效,其健康状态、感官体验与情感体验均呈现倒U形趋势,感官体验与情感体验相互作用,并影响旅居者身心健康;2)从持续性康养旅居循环过程来看,人们的身心健康状态越来越佳,这种健康状态呈波浪式前进和螺旋式上升的趋势;3)康养旅居对人们身心健康的影响机制具有边界条件,分别是时间视角的停留时长、空间视角的柔性边界以及系统视角的自我调节与社会支持。该研究强调了身体反节奏化的革命潜能,为全民康养时代下康养旅居地建设提供了有效路径和理论指导。

Background: spontaneous ascites fluid infection (sAFI) is an extremely serious and frequently encountered complication in cirrhotic patients. We aimed to determine the prevalence of sAFI and the factors associated with it in the largest hospital in Cotonou. Methods: This was a retrospective descriptive and analytical study conducted from January 2013 to July 2019, at the National and University Hospital Hubert Koutoukou Maga (CNHU-HKM) in Cotonou, Benin. All patients followed in the University Clinic of Hepato-Gastroenterology and diagnosed with sAFI were included. Results: Eighty-two patients were included, predominantly males (69.5%), with a mean age of 51.5 ± 14.5 years. Among them, 32 had sAFI, i.e., a prevalence of 39%. Of the 32 cases of sAFI, the culture of ascites fluid was positive in 6 cases (18.7%). The most frequent germ found in sAFI was Escherichia coli (5 patients, 83.3%). The factors associated with sAFI in this study were: abdominal pain (p = 0.004), increased bilirubinemia (p = 0.009), decreased prothrombin level 20 (p = 0.001). Conclusion: sAFI was common in cirrhotic patients in the department. Certain clinical and paraclinical factors were associated with it, as was the severity of cirrhosis. Early diagnosis and aetiological management of cirrhosis could reduce its frequency.
