目的：观察清痹膏联合非布司他治疗急性痛风性关节的临床疗效。方法：将70例急性痛风性关节炎患者随机分为治疗组和对照组，每组各35例。对照组予双氯芬酸钠缓释片合非布司他治疗，治疗组予清痹膏外敷合非布司他治疗。结果：总有效率治疗组为94.3%，对照组为85.7%，2组比较，差异有统计学意义（P＜0.05）；2组疼痛视觉模拟评分（VAS）、尿酸（UA）、红细胞沉降率（ESR）、C反应蛋白（CRP）治疗前后组内比较，差异均有统计学意义（P＜0.05），但治疗后组间比较，差异无统计学意义（P＞0.05）；2组不良反应发生率比较，治疗组优于对照组，差异有统计学意义（P＜0.05）。结论：清痹膏可有效缓解急性痛风性关节炎患者的关节疼痛，且不良反应较少，值得临床推广应用。  相似文献

Isotopic mapping of groundwater perchlorate plumes   总被引：1，自引：0，他引：1  

Sturchio NC  Hoaglund JR  Marroquin RJ  Beloso AD  Heraty LJ  Bortz SE  Patterson TL 《Ground water》2012,50(1):94-102

Analyses of stable isotope ratios of chlorine and oxygen in perchlorate can, in some cases, be used for mapping and source identification of groundwater perchlorate plumes. This is demonstrated here for large, intersecting perchlorate plumes in groundwater from a region having extensive groundwater perchlorate contamination and a large population dependent on groundwater resources. The region contains both synthetic perchlorate derived from rocket fuel manufacturing and testing activities and agricultural perchlorate derived predominantly from imported Chilean (Atacama) nitrate fertilizer, along with a likely component of indigenous natural background perchlorate from local wet and dry atmospheric deposition. Most samples within each plume reflect either a predominantly synthetic or a predominantly agricultural perchlorate source and there is apparently a minor contribution from the indigenous natural background perchlorate. The existence of isotopically distinct perchlorate plumes in this area is consistent with other lines of evidence, including groundwater levels and flow paths as well as the historical land use and areal distribution of potential perchlorate sources.  相似文献   

长江三角洲地区对流层臭氧的变化趋势   总被引：6，自引：0，他引：6       下载免费PDF全文

根据TOR卫星数据分析,我国长江三角洲地区对流层O3柱含量的长期变化就全年和大多数月份而言均为增长趋势,1978-2000年间其年均值的增长趋势为0.82 DU/10 a。这种长期变化趋势所引起的气候效应及其对大气氧化性的影响值得进一步研究。结果表明,长江三角洲地区对流层O3柱含量的季节变化与该地区的临安区域大气本底站的地面O3季节变化有着显著的相关关系,临安站的观测数据具有区域代表性。  相似文献

黔西北地区龙马溪组页岩有机质和脆性矿物的控缝机制     

袁余洋  刘永林  王瑛 《岩石矿物学杂志》2020,39(6):808-818

页岩"甜点"层段中有机质和脆性矿物对裂缝的发育具有极为重要的控制作用，揭示并把握裂缝萌生、发育和演化的机理与规律，对于压裂目标层段的优选以及页岩气增产和稳产具有极为重要的工程实践价值。以黔西北地区龙马溪组页岩为例，通过地化测试、岩石力学实验以及扫描电镜，深入剖析和揭示了"甜点"层段中与有机质和脆性矿物相关的控缝机制，并结合数值模拟实验展现了"甜点"层段中裂缝的形成和演化的完整过程。研究结果表明，有机质和脆性矿物的同步富集为裂缝的发育和演化提供了重要的物质基础，其中裂缝趋向于沿着有机质形成的结构面传播，有机质的孔隙结构对裂缝具有较为明显的诱导机制。在外力作用下，内在积累的能量转化为脆性矿物的变形和变位，脆性矿物含量越高者裂缝发育能力越强，裂缝发育程度越高。数值模拟实验呈现了一种由于有机孔隙和脆性矿物所导致的应力集中从而诱发裂缝萌生和演化的整个过程。该研究成果可为深化认识裂缝的成因机理以及压裂施工过程中相关压裂参数的调整提供一定的借鉴与参考。  相似文献   

Influence of aquifer properties on phytoremediation effectiveness     

Matthews DW  Massmann J  Strand SE 《Ground water》2003,41(1):41-47

Recent research has shown that planting deep-rooted trees, such as poplar, can take up and degrade important ground water pollutants such as trichloroethylene (TCE) as they transpire water from the capillary fringe of shallow contaminated aquifers. The effect of hydrogeologic factors on the minimum plantation area needed to prevent downgradient migration of contaminated ground water is not well known. Accordingly, the objective of this research was to identify the hydrogeologic parameters that control phytoremediation effectiveness. We used a numerical ground water flow model to evaluate the effect that natural variations in hydrogeologic parameters and growing season duration have on the minimum plantation area required for capture. We found that the plantation area that was needed to completely capture a ground water contamination plume was directly proportional to aquifer horizontal hydraulic conductivity, saturated thickness, and ground water gradient. The plantation area needed for capture increased nonlinearly with increasing plume width, aquifer anisotropy, and decreasing growing season duration. The plantation area needed for capture was generally insensitive to aquifer-specific yield and storativity. Steady-state simulations can be used to predict the plantation area needed for capture in many applications. A particularly important finding of this work is that evapotranspiration fluxes through plantations appropriately sized to contain the plume substantially exceeded the ground water flux through the plume itself.  相似文献
