Petroleum Science 2024年第3期21卷 1865-1874页

Viscoelastic surfactants(VES)are often used as viscous diverters in acidizing stimulation to prolong the acid consumption time and maximize zonal coverage of the acid for improving well ***,the ceiling temperature of commercial VES cannot exceed 120℃in practical use because of the poor thermal stability and fragile molecular structure,hindering their implementation in hightemperature oil reservoirs,i.e.,≥150℃.Here we synthesized a novel C22-tailed diamine,N-erucaminopropyl-N,N-dimethylamine(EDPA),and examined comparatively its rheological behavior,assemblies morphology and molecular stability in 20 wt%HCl with a commercial VES,erucyl dimethyl amidopropyl betaine(EDAB).The feasibility of EDPA for acidizing stimulation was assessed by acid etching of carbonate rock with its HCl solution at 150℃.Rheological results showed that the 2.5 wt%EDPA—20 wt%HCl solution maintains stable viscosity of 90 m Pa s at 150℃for 60 min,while that of 2.0 wt%EDAB HCl solution is just 1 m Pa s under identical conditions.1H NMR spectra and cryo-TEM observations revealed that the chemical structure and self-assembled architectures of EDPA remained intact in such context,but the EDAB suffered from degradation due to the hydrolysis of the amide group,accounting for the poor heat-resistance and *** reaction rate of 2.5 wt%EDPA HCl solution with carbonate rock was one order of magnitude lower than that of 20 wt%HCl solution at 150℃,underpinning the potential of EDPA to be used in the high-temperature reservoirs *** work improved the thermal tolerance of VES in highly concentrated HCl solution,paving a feasible way for the acidization of high-temperature reservoir environments(~150℃).

Astragalus mongholicus ameliorates renal fibrosis by modulating HGF and TGF-β in rats with unilateral ureteral obstruction

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2009年第5期10卷 380-390页

作者： Chuan ZUO Xi-sheng XIE hong-yu QIU yao DENG Da ZHU Jun-ming FAN Department of Nephrology West China Hospital of Sichuan University Chengdu 610041 China

Astragalus mongholicus （AM） derived from the dry root ofAstragalus membranaceus Bge. var. mongolicus （Bge.） Hsiao is a widely used traditional Chinese medicine. The present study investigated the potential role of AM on renal fibrosis on a rat model of unilateral ureteral obstruction （UUO）. We divided 48 Sprague-Dawley rats randomly into 4 groups： sham-operated group （Sham）, untreated UUO group, AM-treated （10 g/（kg.d）） UUO group, and losartan-treated （20 mg/（kg.d）） UUO group as positive control. Haematoxylin ＆ eosin （HE） and Masson staining were used to study the dynamic histological changes of the kidneys 7 and 14 d after operation. The expressions of fibronectin （FN）, type I collagen （coil）, hepatocyte growth factor （HGF）, transforming growth factor-β1 （TGF-β1）, and eL-smooth muscle actin （α-SMA） were analyzed by real-time polymerase chain reaction （PCR）, immunohistochemistry staining, and Western blot. Results show that, similar to losartan, AM alleviated the renal damage and decreased the deposition of FN and coil from UUO by reducing the expressions of TGF-β1 and α-SMA （P〈0.05）, whereas HGF increased greatly with AM treatment （P〈0.05）. Our findings reveal that AM could retard the progression of renal fibrosis. The renoprotective effect of AM might be related to inhibition ofmyofibroblast activation, inducing of HGF and reducing of TGF-β1 expression.

【目的】弄清广东省鹤山市尾叶桉(Eucalyptus urophylla)与厚荚相思(Acacia crassicarpa)造林后的土壤阳离子交换量(CEC)特征及其影响因子。【方法】对鹤山市共和镇造林15年的尾叶桉和厚荚相思人工纯林的土壤CEC和生态化学计量特征进行测定,分析两种树种造林后土壤CEC和其他指标特征及两者间相关关系,利用主成分分析法综合评价两树种造林后对土壤CEC的影响。【结果】厚荚相思林土壤CEC、交换性盐基总量(TEB)和盐基饱和度(BS)均显著大于尾叶桉林。厚荚相思林土壤交换性Ca^(2+)含量显著高于尾叶桉林,而两种林分土壤交换性K+、Na^(+)和Mg^(2+)含量无显著差异。Ca^(2+)/Mg^(2+)、Ca^(2+)/K+和(Ca^(2+)+Mg^(2+))/K+表现为厚荚相思林显著大于尾叶桉林。相关性分析显示,尾叶桉林土壤CEC与土壤自然含水量(SWC)、总有机碳(TOC)、总氮(TN)呈极显著正相关;厚荚相思林土壤CEC与TN、C/N呈极显著正相关,与C/P、C/N/P显著正相关。主成分分析表明,土壤TEB、总磷(TP)、Na^(+)、BS、Ca^(2+)、Mg^(2+)和pH是影响该区域土壤CEC的重要因素。【结论】在鹤山共和样地,与尾叶桉造林相比,厚荚相思造林显著提高了土壤CEC、TEB和BS,说明其土壤保肥和供肥能力更具优势。

Cutaneous and systemic plasmacytosis （CSP） is a rare condition characterized by a clinical triad of cutaneous lesions, polyclonal hypergammaglobulinemia, and superficial lymphadenopathy. The condition is described primarily in middle-aged Asian patients and particular in Japanese individuals,l A previous study suggest a male ： female ratio of 1 to 0.6, and an age of onset ranging from 20 to 62 years, with both a mean and median age of 37 years.2 Here, we report a Chinese case of CSP, who is the youngest patient of Chinese decent in literature.
