为探究不同钝化材料组合及用量对玉米吸收Cd、Pb的阻控效果,实现重金属污染耕地的安全利用,以“华兴单88”为供试玉米,采用田间试验方法,研究喷施叶面阻控剂(JGL)、不同用量有机肥(YJF1和YJF2)、腐植酸(FZS)和土壤重金属钝化剂(DHJ)以及YJF、FZS和DHJ与JGL的组合(YJF1^(+)/YJF2^(+)、FZS^(+)和DHJ^(+))对玉米生物性状和各部位Cd、Pb含量以及富集系数(BCF)、转运系数(TF)的影响,并根据玉米籽粒Cd、Pb的BCF推算土壤Cd、Pb风险阈值(T)作为阻控效果的评价指标。结果表明,9种阻控措施处理玉米产量较CK提高14.4%~32.3%,增产能力表现为JGLDHJ>YJF1>DHJ^(+)>YJF1^(+)>YJF2>FZS>YJF2^(+)>FZS^(+);供试玉米各部位Cd、Pb含量及富集能力均表现为根部最强,籽粒最弱,Cd、Pb转运能力均表现为茎部-叶部最强,根部-茎部最弱。通过田间试验证明,10种处理供试玉米产量和Cd、Pb阻控效果均表现为FZS+>YJF2^(+)>FZS>YJF2>YJF1^(+)>DHJ^(+)>YJF1>DHJ>JGL>CK;9种阻控措施处理供试玉米土壤TCd和TPb分别介于11.0~23.1 mg·kg^(-1)和109.9~218.0 mg·kg^(-1)之间。在该试验条件下,FZS作为增产以及Cd、Pb阻控效果最好的钝化材料,建议在Cd轻中度污染土壤的玉米产区推广使用,FZS^(+)作为增产以及Cd、Pb阻控效果最好的组合措施建议在Cd重度污染土壤的玉米产区推广使用。

溶解性有机质(DOM)对于指示水环境污染具有重要作用,而沉积物作为水环境内源污染的主要来源,研究沉积物DOM光谱特性对于解释该区域水环境污染具有重要意义.利用紫外-可见吸收光谱和三维荧光光谱,并结合平行因子分析法(PARAFAC),分析了袁河流域沉积物DOM的物质组成、来源特征及其影响因素.结果表明,袁河流域沉积物ω(TN)、ω(TP)和ω(OM)平均值分别为0.25、0.66和21.22 g·kg^(-1),随水流方向TN和TP含量呈增加趋势.袁河流域沉积物DOM主要为陆源输入,下游区域沉积物DOM的有色溶解性有机质浓度和芳香性明显高于上、中游区域.通过PARAFAC解析出3个腐殖质组分(C1、C3、C4)和1个类蛋白组分(C2),以腐殖质组分为主,荧光物质在下游区域更高.此外,干流及下游区域中沉积物理化性质对沉积物DOM光谱参数变化的解释量更高.其中,磷污染与沉积物DOM的陆源腐殖质具有同源性.以上结果说明在人类活动较强的区域范围内DOM光谱性质对水环境污染具有指示意义.

采用溶剂法制备乙二胺四乙酸二酐改性杨树末(EPSD)吸附剂。采用SEM、FTIR和BET分析对EPSD进行了表征,并通过静态和动态吸附实验,探讨了EPSD对柠檬酸/酒石酸络合镉的吸附特性,并与对游离态镉的吸附特性进行了比较。结果表明,杨树末表面被引入羧基改性。EPSD吸附游离态和络合态Cd(Ⅱ)溶液体系的最优pH值均为6.0左右;吸附Cd(Ⅱ)的行为均符合拟二级动力学模型,主要由化学吸附控制重金属离子的吸附速率;Langmuir等温模型可以更好地描述Cd(Ⅱ)的吸附等温线,说明吸附都是单分子层的;热力学分析表明,吸附反应均为自发的吸热过程。随着进水流速增大,EPSD动态吸附游离态和络合态Cd(Ⅱ)到达穿透点的时间逐渐提前,进水流速为1.5 mL/min时最适合EPSD的动态吸附;对游离态Cd(Ⅱ)和酒石酸络合Cd(Ⅱ)的吸附容量利用率可分别达到54.93%~68.95%,53.17%~70.47%。EPSD对水中游离态和络合态Cd(Ⅱ)吸附均具有良好的应用前景。

Continuous regional arterial infusion for the treatment of severe acute pancreatitis: a meta-analysis

引用

Hepatobiliary & Pancreatic Diseases International 2015年第1期14卷 10-17页

作者： Feng-Jiao Yong xuan-yue Mao Li-Hui Deng Ming-Ming Zhang Qing Xia Sichuan Provincial Pancreatitis Center Department of Integrated Traditional and Western Medicine West China Hospital Sichuan University Chinese Evidenced-Based Medical Center West China Hospital Sichuan University

BACKGROUND： Continuous regional arterial infusion（CRAI） is a drug delivery system, which dramatically increases the drug concentration in the pancreas. Previous clinical and basic studies have demonstrated the possible therapeutic efficacy of CRAI for severe acute pancreatitis（SAP）. This meta-analysis of all published randomized controlled trials（RCTs） was conducted to assess the efficacy and safety of CRAI for the treatment of SAP. DATA SOURCES： Up to August 10, 2014, RCTs comparing CRAI with intravenous infusion for SAP in PubM ed, Embase, EBSCO, MEDLINE, Science Citation Index Expanded, Cochrane Library, China Academic Journals Full-Text Database, Chinese Biomedical Literature Database, and Chinese Scientific Journals Database were selected by two independent reviewers. The relative risk（RR） and their 95% confidence intervals（CI） for duration of elevated serum amylase and urine amylase, duration of abdominal pain, infection rate, incidence of complication, overall mortality, curative rate, hospital stay and details of subgroup analysis were extracted. Meta-analyses were made using the software Review Manager（RevM an version 5.10）.RESULTS： Six RCTs with 390 patients meeting the inclusion criteria were included in the final analysis. Compared with intravenous infusion route, CRAI significantly shortened the duration of elevated urine amylase（MD=-2.40, 95% CI=-3.20,-1.60; P〈0.00001） and the duration of abdominal pain（MD=-1.46, 95% CI=-1.94,-0.98; P〈0.00001）, decreased the incidence of complication（RR=0.35, 95% CI=0.15, 0.81; P=0.01） and overall mortality（RR=0.25, 95% CI=0.08, 0.78;P=0.02）, shortened the duration of hospital stay（MD=-10.36, 95% CI=-17.05,-3.68; P=0.002）, and increased the curative rate（RR=1.66, 95% CI=1.13, 2.46; P=0.01）. No mortality and catheter-related infections due to CRAI administration was reported in these studies. Subgroup analysis showed that the combination of drug administration via CRAI did not significantly improve the ***
