1中国东北松嫩平原地下水水化学特征与演变规律显示文摘在全球气候变化和高强度人类活动的影响下,松嫩平原地下水环境日益恶化,已成为制约生态环境建设和经济社会发展的重要因素。选取具有典型代表意义的洮儿河流域作为研究区,对地下水进行系统取样分析,综合运用描述性统计、相关性分析、离子比例系数和Piper三角图示法,全面系统地研究地下水水化学的时空变异特征与演变规律,揭示了风化溶滤、蒸发浓缩、阳离子交换和人为混合是控制地下水质演变的主要水文化学过程,从而为流域乃至松嫩平原盐渍土区水资源可持续开发利用和管理提供科学依据。章光新 邓伟 何岩 Ramsis Salama 2006水科学进展2006,17,1:165
2水文响应单元法在盐渍化风险评价中的应用显示文摘运用水文响应单元(HRUs)法评价洮儿河流域地下水环境空间变化对盐渍化风险等级的影响过程,利用反映地下水环境空间变化的3 个重要参数:水文区权重(HZ)、水位埋深(DTW)和水位上升速率(RR),由其3个等级网格值算术相乘HRU = DTW*RR*HZ在GIS 平台上生成2001 年水文响应单元图。结果表明:(1)洮儿河流域整体上盐渍化风险非常小,低风险区主要分布在水文区A、水文区B和水文区D中的安广镇、烧锅镇一带,主要原因是由于区域地下水位下降、水文区A水文及水文地质条件较好;(2)高风险区主要分布在莫莫格湿地、镇赉县境内和来福-叉干镇一带,主要是由于嫩江排泄通道受阻、地表水体的补给以及水田不合理的灌溉造成的。章光新 邓伟 何岩 RAMSIS Salama 2005吉林大学学报(地球科学版)2005,35,3:8
3Dietary copper triggers onset of fulminant hepatitis in the Long-Evans cinnamon rat model显示文摘AIM:To investigate the impact of dietary copper given at different time points on the onset of fulminant hepatitis. METHODS:The Long-Evans cinnamon (LEC) rat model of Wilson's disease (WD) was used to study the impact of high dietary copper (hCu) on the induction of fulminant hepatitis at early or late time points of life. High Cu diet was started in rat pups or in adults (month 5) for three months. Animals that received reduced dietary copper (rCu) throughout their lifetime served as a control. Hepatitis-associated serum markers (alanine aminotransferase, aspartate transaminase, bilirubin) were analyzed in animal groups receiving hCu or rCu. Liver copper content and liver histology were revealed at sacrifice. A set of 5 marker genes previously found to be affected in injured liver and which are related to angiogenesis (Vegfa), fat metabolism (Srebf1), ex-tracellular matrix (Timp1), oxidative stress (Hmox1), and the cell cycle (Cdkn1a) were analyzed by real-time polymerase chain reaction. RESULTS:Regardless of the time point when hCu was started, LEC rats (35/36) developed fulminant hepatitis and died. Animals receiving rCu (36/36) remained healthy, did not develop hepatitis, and survived long term without symptoms of overt disease, although liver copper accumulated in adult animals (477 ± 75 μg/g). With regard to start of hCu, onset of fulminant hepatitis was significantly (P < 0.001) earlier in adults (35 ± 9 d) that showed pre-accumulation of liver copper as compared to the pup group (77 ± 15 d). Hepatitis-associated serum markers, liver copper and liver histology, as well as gene expression, were affected in LEC rats receiving hCu. However, except for early and rapid onset of hepatitis, biochemical and molecular markers were similar at the early and late time points of disease. CONCLUSION:Rapid onset of fulminant hepatitis in asymptomatic LEC rats with elevated liver copper suggests that there is a critical threshold of liver copper which is important to trigger the course of WD.Ramsi Siaj Vanessa Sauer Sandra Stppeler Hans-Ullrich Spiegel Gabriele Khler Andree Zibert Hartmut HJ Schmidt 2012World Journal of Gastroenterology2012,18,39:3
