Botanic gardens should lead the way to create a "Garden Earth" in the Anthropocene

引用

Plant Diversity 2017年第6期39卷 331-337页

作者： Charles H.Cannon Chai-Shian kua The Center for Tree Science The Morton Arboretum Science and Conservation The Morton Arboretum Shanghai Engineering Research Center for Urban Tree Ecology and Applications

The strength and expertise that botanic gardens bring to conservation are based on their detailed knowledge and understanding of the care. management, and biology of a diversity of plant species. This emphasis on the organism has led to many ex-situ and in-situ conservation programs aimed at protecting endangered species, restoring threatened populations, and establishing living plant and seed collections of endangered species. In China, the scale and pace of change in land and resource use, often leading to environmental degradation, has created a strong emphasis on improving environmental conditions. If done properly, being "green" can be a surprisingly complex issue, because it should encompass and exploit the whole of plant diversity and function. Unfortunately, 'green' often includes a small portion of this whole. Earth's rich plant diversity presents considerable opportunity but requires expertise and knowledge for stable and beneficial management. With the dawning of the Anthropocene, we should strive to live on a "Garden Earth", where we design and manage our environments, both built and natural, to create a healthy, beneficial living landscape for people and other organisms. The staff of botanic gardens worldwide and the living collections they maintain embody the best examples of sustainable, beautiful, and beneficial environments that thrive on plant diversity. This expertise should be a fundamental resource for agencies in all sectors responsible for managing and designing "green" infrastructure. Botanic gardens should actively engage and contribute to these opportunities, from large public infrastructure projects to small private conservation efforts. Here, we discuss several ongoing conservation efforts, primarily in China, and attempt to identify areas where botanic gardens could make a significant and meaningful difference.

One of the challenges of promoting accelerated carbonation curing(ACC)of concrete as a carbon sequestration strategy is ensuring that carbonation will not deteriorate mechanical *** study examined the mechanical strength,water sorptivity and carbonation efficiency of ten types of mortar containing dry or pre-soaked biochar subjected to internal and/or external *** results obtained enabled a typology of ACC to be proposed,in which the carbon dioxide absorption of mortar containing various types of CO_(2)-dosed biochar ranged between 0.022%and 0.068%per unit dosage *** particular,the mortar containing dry biochar dosed with carbon dioxide was the top candidate for concurrently increasing both compressive strength(54.9 MPa)and carbon dioxide absorption(0.055%per unit dosage hour).Mortar containing pre-soaked biochar dosed with carbon dioxide was identified as a strategy that achieved the highest carbonation efficiency(0.068%per unit dosage hour),but it also reduced compressive strength(45.1 MPa).Collectively,the proposed typology offers a useful overview of the different ways by which biochar can be used to tune ACC in mortar,according to any technical constraints and/or intended functions of the carbonated concrete components.

目的:探究瑞香素对胫骨骨折大鼠骨痂形成、血管生成及缺氧诱导因子-1α(HIF-1α)/血管内皮生长因子(VEGF)信号通路的影响。方法:构建胫骨骨折大鼠模型,将120只胫骨骨折大鼠随机分成模型组、瑞香素低剂量组(30 mg/kg)、瑞香素中剂量组(60 mg/kg)、瑞香素高剂量组(90 mg/kg)剂量组、瑞香素高剂量+HIF-1α抑制剂YC-1组(90 mg/kg瑞香素+10 mg/kg YC-1),每组24只。另取24只正常大鼠仅暴露胫骨,穿入克氏针,不切断胫骨,设为假手术组。各组大鼠进行相应给药干预8周。X射线观察骨痂形成情况,并计算骨痂体积。微计算机断层扫描(Micro-CT)分析骨折折断处骨痂组织和假手术组相同部位骨组织骨体积分数(BV/TV)、骨小梁数量(Tb.N)、骨小梁厚度(***)和骨密度(BMD)。HE染色观察胫骨骨折处骨组织及假手术组大鼠相同部位骨组织形态学变化,并计算新生血管数量及血管面积。酶联免疫吸附法(ELISA)检测血清中碱性磷酸酶(ALP)、骨钙素(OCN)水平。蛋白印迹实验检测胫骨骨折处骨痂组织及假手术组骨膜组织HIF-1α和VEGF蛋白表达。结果:与假手术组比较,模型组胫骨骨组织破坏严重,骨小梁稀疏紊乱,成骨细胞数量明显减少,BV/TV、Tb.N、***、BMD、新生血管数量及血管面积、HIF-1α和VEGF蛋白表达水平降低,ALP、OCN水平升高(均P<0.05)。与模型组比较,瑞香素低、中、高剂量组骨组织中骨痂依次增多,骨小梁生成增加且排列有序,毛细血管逐渐丰富,聚集的成骨细胞数量依次增加,骨组织破坏减轻,骨痂体积、BV/TV、Tb.N、***、BMD、新生血管数量及血管面积、ALP、OCN、HIF-1α和VEGF蛋白表达水平依次升高(均P<0.05)。与瑞香素高剂量组比较,瑞香素高剂量+YC-1组骨痂、骨小梁生成、毛细血管、成骨细胞数量减少,骨组织破坏加重,骨痂体积、BV/TV、Tb.N、***、BMD、新生血管数量及血管面积、ALP、OCN、HIF-1α和VEGF蛋白表达水平降低(均P<0.05)。结论:瑞香素可能通过激活HIF-1α/VEGF信号通路促进胫骨骨折大鼠骨痂形成、血管生成,从而加速骨愈合。

误服误用含吡咯里西啶生物碱(pyrrolizidine alkaloid,PA)的中草药是导致我国临床肝窦阻塞综合征(hepatic sinusoidal obstruction syndrome,HSOS)的主要原因,利尿剂是目前临床上治疗PA致HSOS的常用药物之一。泽泻作为传统利尿中药,但其利尿机制仍未完全明确,且尚未有从利尿角度阐释泽泻改善PA致HSOS的报道。基于课题组前期研究,本研究以泽泻三萜23-乙酰泽泻醇B(alisol B 23-acetate,AB23A)为代表性药物,评价其对毒性PA千里光碱致小鼠急性肝损伤的保护作用,并进一步考察AB23A对模型小鼠水液失衡的影响。所有动物实验经上海中医药大学实验动物伦理委员会批准(批准号PZSHUTCM220808017),符合实验动物伦理相关规范。小鼠单次灌胃千里光碱(50 mg·kg^(-1))造模(SEN组),并设AB23A(40 mg·kg^(-1))干预组(AB23A+SEN组)、溶剂对照组(Ctrl组)和AB23A对照组(AB23A组)。结果表明,AB23A可明显降低千里光碱致急性肝损伤小鼠血清肝功能生化指标水平,缓解肝细胞凝固性坏死、肝窦淤血等病理状态;此外,AB23A还可改善小鼠血清肾功能指标,改善千里光碱造成的尿液排泄减少、机体电解质紊乱,并降低千里光碱及其代谢产物的含量。进一步测定小鼠水平衡通路相关蛋白和mRNA的表达,AB23A可明显下调千里光碱模型组小鼠水通路蛋白2(aquaporin-2,AQP2)、血管紧张素II 1型受体的蛋白和mRNA表达水平,抑制AQP2向顶端质膜运输,并降低血清血管紧张素II含量。体外研究进一步证实AB23A可调节肾脏内髓集合管细胞AQP2的表达。本研究表明,AB23A可调节千里光碱致急性肝损伤小鼠肾脏髓质AQP2,影响其对水的重吸收,改善水液平衡。研究结果进一步加深了对泽泻传统利尿活性的认识,为临床利用泽泻治疗PA致HSOS提供实验基础和理论依据。
