体外培育牛黄通过调控小胶质细胞极化及炎症小体活性干预脑缺血再灌注损伤

open access: yes浙江大学学报. 医学版
目的:探讨体外培育牛黄(ICCB)减轻脑缺血再灌注损伤(CIRI)的机制。方法:分别构建大脑中动脉阻塞(MCAO)大鼠模型和氧糖剥夺/再灌注(OGD/R)BV2细胞模型。其中,大鼠模型于脑缺血1.5 h再灌注72 h后进行改良的神经损伤严重程度评分(mNSS),并测定脑组织含水量和脑梗死体积;苏木精-伊红染色法检测大脑皮层及海马CA1区组织结构病理变化;免疫荧光法检测皮层小胶质细胞极化情况和NOD样受体热蛋白结构域相关蛋白(NLRP)3炎症小体的表达情况。BV2细胞于氧糖剥夺0.5 h再灌注24 h后 ...

Analysis on the characteristics and driving forces of spatiotemporal changes of Zhejiang water system(浙江省水域系统时空变化特征及驱动力分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2022
基于浙江省1980—2020年8期土地利用数据,分析了浙江省不同时期水域系统时空格局、水面率、转换趋势、景观格局等特征,揭示了水域系统面积变化的驱动因素。结果表明:(1)浙江省水域面积总体呈增加趋势,河流、滩地面积缩减,湖泊、水库坑塘、滩涂面积增加。水域系统转移集中于河流、湖泊和沿海一侧。(2)浙江省水域景观格局MPS、NP、LST、FRA、CCONTAG指数上升,PD、ED、LPI、COHESION、AI指数下降,突出反映了水域景观破碎化、离散化、复杂化。(3)不同地级市水域系统面积存在差异 ...

Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...

基于景观格局指数的钱江源国家公园生态系统完整性评价分析

open access: yes, 2020
利用浙江省开化县2014年二类资源调查数据,采用景观格局分析方法,从景观尺度分析了钱江源国家公园体制试点区(以下简称钱江源国家公园)植被的构成和破碎化程度,研究了钱江源国家公园的完整性和原真性。结果表明,钱江源国家公园的景观类型以常绿阔叶林、天然针叶林和杉木Cunninghamialanceolata林为主;在核心保护区和生态保育区内分布着大面积呈原始状态的低海拔中亚热带常绿阔叶林,具有重要保护价值。对各功能区景观破碎化分析表明,破碎化程度由大到小表现为:游憩展示区>传统利用区>生态保育区>核心保护区 ...

浙江庆元天然林中笔罗子生长量的测定与分析

open access: yes, 2018
对浙江庆元天然林中45年生笔罗子Meliosma rigida的树高、胸径和材积3个树干解析数据进行分析,研究其生长规律。结果表明:(1)笔罗子树高的生长受环境条件的影响很大,在生长期内不稳定;胸径和材积的高速生长期集中在26 a以后,因此前26 a为最佳抚育期。(2)材积的连年生长曲线和平均生长曲线在生长期内并没有相交,因此不能确定笔罗子的数量成熟龄。(3)利用IBM SPSS Statistics 19.0对年龄与树高、胸径和材积进行拟合计算,3个拟合的数学模型都具有较高的精度 ...
