乡村治理体系的完善在国家治理体系现代化进程中有重要作用。随着互联网的快速普及,新媒体在乡村治理中的作用逐渐凸显。但是,新媒体融入乡村治理存在着基础规则匮乏、过程强调行政导向、协调机制不足、网络空间失序等困境。结构功能主义与乡村治理法治化深度嵌合,也为探索新媒体推动乡村治理法治化提出更加适配的研究视角。重视规范构造、牢固法治理念、建立协同参与机制、强化监管体系能够优化新媒体融入乡村治理法治化的适应、目标、整合和维模功能。

冶炼污染场地土壤中多重金属复合污染的特征增大了对土壤的修复和最终利用的难度。本研究深入调查了某铅锌冶炼场地土壤重金属污染特征,针对性地制定多种联合稳定化修复方案,采用高精度混合装备添加药剂,实施稳定化修复工程。结果表明,Cd、Pb、Zn和As是场地土壤中最主要的重金属污染物,其中Cd、Pb、As的超标率分别为75.80%、76.43%、88.54%。重金属的分布模式与土壤理化性质、污染物迁移路径、水文地质条件、地层岩性、冶炼工艺、厂区功能布局等密切相关。土壤重金属污染主要来源于冶炼粉尘、废渣和废水排放等冶炼活动。稳定化工程效果显示,在药剂与土壤混匀程度不低于90%时,采用无机混合药剂与TJ400螯合剂的组合方案,对土壤稳定化处理7 d后,土壤中Cd、Pb和As同步稳定化效果最好。本研究结果可对多金属重污染场地土壤的稳定化修复提供实践指导。

Background: Ankylosing spondylitis was reported to associate with an increased risk of cerebrovascular diseases. In this article, we aimed to report the first case of ankylosing spondylitis associated with moyamoya disease treated with encephalo-duroarterio-synangiosis. Case presentation: A 9-year-old boy with ankylosing spondylitis appeared a symptom of repeated transient ischemic attacks which performed as left hemiparesis. Magnetic resonance angiography showed a typical finding of left anterior cerebral artery, bilateral middle cerebral arteries and the supraclinoid portion of the right internal carotid artery stenosis with an abnormal vascular network at the base of the brain, diagnosed with moyamoya disease. He received a medication treatment but did not underwent revascularization surgery. After three months, ankylosing spondylitis symptoms got some relief, whereas transient ischemic attacks was more frequency. Due to the bad cerebral blood flow on acetazolamide computed tomography perfusion and poor clinical manifestation, he underwent a right encephalo-duroarterio-synangiosis. Postoperatively, the symptoms of transient ischemic attacks disappeared. Conclusions: We reported the first case of ankylosing spondylitis associated with moyamoya disease. Moyamoya disease could appear in patients with ankylosing spondylitis. Revascularization surgery probably is an effective treatment for preventing preoperative ischemic events recurrence.
