Short-Term Influence of Herbicide Quinclorac on Enzyme Activities in Flooded Paddy Soils

Pedosphere 2004年第1期14卷 71-76页

作者： lüzhen-mei minhang yeyang-fang CollegeoflifeSciences ZhejiangUniversityHangzhou310029（China）

The influence of quinclorac (3,7-dichloroquinoline-8-carboxylic acid) on enzyme activities in flooded paddy soils was assessed under laboratory conditions. The enzymes differed markedly in their response to quinclorac. Quinclorac inhibited proteinase, hydrogen peroxidase, phosphorylase, and urease *** higher the concentration of quinclorac applied, the more significant the inhibition to these observed activities with a longer time required to recover to the level of the control. However, soils supplemented with quinclorac were nonpersistent for proteinase, phosphorylase and urease as opposed to soils without quinclorac. Dehydrogenase activity was also sensitive to quinclorac. Three soil samples with concentrations of quinclorac higher than 1 μg g-1 soil declined to less than 20% of that in the control. However, the highest dehydrogenase activity (up to 3.28-fold) was detected in soils with 2 μg g-1 soil quinclorac on the 25th day after treatment. Quinclorac had a relatively mild effect on saccharase activity at the concentrations used in this experiment and a stimulatory one on soil respiration when added to soil at normal field *** it was inhibited at higher concentrations in paddy soils. Quinclorac is still relatively safe to the soil ecosystem when applied at a normal concentration (0.67 μg g-1 dried soil) but may have some effects on soil enzymes at higher concentrations.

Characterization and phylogenetic analysis of a phenanthrene-degrading strain isolated from oil-contaminated soil

Journal of Environmental Sciences 2004年第4期16卷 589-593页

作者： XIAYing minhang lUzhen-mei yeyang-fang CollegeoflifeScience ZhejiangUniversityHangzhou310029China

Bacterium strain EVA17 was isolated from an oil-contaminated soil, and identified as Sphingomonas sp. based on analysis of 16S rDNA sequence,cellular fatty acid composition and physiological-chemical tests. The salicylate hydroxylase and catechol 2,3-dioxygenase(C23O) were detected in cell-free lysates, suggesting a pathway for phenanthrene catabolism via salicylate and catechol. Alignment showed that both of the C23O and GST genes of the strain EVA17 had high similarity with homologues of strains from genus Sphingomonas. The phylogenetic analysis based on 16S rDNA and C23O gene sequence indicated that EVA17 should be classified into genus Sphingomonas, although the two phylogenetic trees were slightly different from each other. The results of co-amplification and sequence determination indicated that GST gene should be located upstream of the C23O gene.

目的:从真实世界数据出发,分析并评价某院2个时间段使用非甾体抗炎药(NSAIDs)的门诊患者分布特征、用药特点、用药情况等,为临床合理用药提供参考。方法:回顾性收集2021年12月1日~2022年1月15日(A时段)与2022年12月1日~2023年1月15日(B... 详细信息

目的:从真实世界数据出发,分析并评价某院2个时间段使用非甾体抗炎药(NSAIDs)的门诊患者分布特征、用药特点、用药情况等,为临床合理用药提供参考。方法:回顾性收集2021年12月1日~2022年1月15日(A时段)与2022年12月1日~2023年1月15日(B时段)期间某院门诊使用NSAIDs患者的性别、年龄等基本信息,梳理总结NSAIDs的品种、使用频率、用药天数等,并整理限定日剂量(DDD),计算用药频度(DDDs)、限定日费用(DDC)及药物利用指数(DUI)等,比较2个时间段NSAIDs的应用情况,选择重点药品进行用药分析与评价。结果:A与B时段分别有5600例与10916例患者使用NSAIDs,2个时间段各自使用13种与28种药品。尤其在B时段出现了用药品种、用药量剧增现象,其中DDDs排名前3位的是阿司匹林肠溶片(规格100mg)、双氯芬酸钠双释放肠溶胶囊、布洛芬缓释胶囊;DDDs增幅居前3位的是布洛芬混悬液(929.05%)、布洛芬缓释胶囊(322.10%)、氨麻美敏片(Ⅲ)(319.92%)。复方制剂的使用率上升至首位(39.22%)。吲哚布芬片的DDC值最高(31.47元),阿司匹林肠溶片(规格25mg)DDC值最低(0.26元)。大多数NSAIDs的DUI<1,提示该院NSAIDs使用基本合理。结论:在目标时间范围内,该院门诊NSAIDs使用基本合理。

Intrahepatic cholangiocarcinoma(iCCA)can originate from the large bile duct group(segment bile ducts and area bile ducts),small bile duct group(septal bile ducts and interlobular bile ducts),and terminal bile duct group(bile ductules and canals of Hering)of the intrahepatic biliary tree,which can be histopathological corresponding to large duct type iCCA,small duct type iCCA and iCCA with ductal plate malformation pattern,and cholangiolocarcinoma,*** challenge in pathological diagnosis of above subtypes of iCCA falls in the distinction of cellular morphologies,tissue structures,growth patterns,invasive behaviors,immunophenotypes,molecular mutations,and surgical *** these reasons,this expert consensus provides nine recommendations as a reference for standardizing and refining the diagnosis of pathological subtypes of iCCA,mainly based on the 5th edition of the World Health Organization Classification of Tumours of the Digestive System.
