目的探讨Wnt/β-catenin通路在糖尿病肾病(DN)大鼠肾脏的表达及化瘀通络中药对其的干预作用。方法 60只大鼠中选取10只为对照组,其余大鼠给予高糖高脂饲料喂养联合ip小剂量链脲佐菌素(STZ)制备DN模型。成模大鼠随机分为模型组、厄贝沙坦组、化瘀通络中药组,各组ig给药,20周末检测24 h尿蛋白定量,RT-PCR法检测Wnt4、β-catenin m RNA表达,免疫组化及Western blotting法检测Wnt4、β-catenin蛋白的表达。结果与对照组比较,模型组大鼠24 h尿蛋白定量及Wnt4、β-catenin m RNA和蛋白的表达量明显升高(P<0.01)。与模型组比较,中药组及厄贝沙坦组24 h尿蛋白定量及Wnt4、β-catenin m RNA和蛋白的表达量明显降低(P<0.05、0.01)。结论化瘀通络中药可减少DN大鼠尿蛋白,且能够抑制大鼠肾脏存在的Wnt/β-catenin通路高表达,该作用可能是其减少蛋白尿排泄的主要途径之一。

Palladium installed copper-organic framework for C–C coupling reactions

Science China Chemistry 2025年

作者： Yu-Mei Wang Mei-Xia Tao Kai-Ming Mo Xu chen Shu-hua Zhong Elena S Shubina Guo-Hong Ning Dan Li College of Chemistry and Materials Science Guangdong Provincial Key Laboratory of Supramolecular Coordination ChemistryJinan University A.N.Nesmeyanov Institute of Organoelement Compounds Russian Academy of Sciences

The formation of C–C bonds is a crucial aspect of organic synthesis. Synthesists' long-term objective is to identify novel catalysts to optimize reaction systems based on traditional transition metal catalysis. This study explores the synthesis and catalytic potential of palladium-installed covalent metal-organic frameworks(CMOFs) based on copper cyclic trinuclear units(Cu-CTUs). By incorporating palladium ions into the imine-based framework JNM-7 through a straightforward immersion method, we achieved a notable enhancement in catalytic activity for critical C–C coupling reactions, including C–H arylation and Sonogashira cross-coupling. The resulting JNM-7-Pd demonstrated remarkable stability and recyclability, maintaining its efficiency over at least three cycles without any decline in efficiency.

研究了固溶热处理对一种Re含量为6.5%(质量分数)的第三代单晶高温合金组织及持久性能的影响,实验结果表明:合金铸态下存在明显的凝固偏析,枝晶间区域存在大量的(γ+γ′)共晶组织。固溶过程中,共晶组织在1 335℃以上开始快速溶解,但难熔元素,尤其是Re元素的偏析需要在1 360℃以上才能有明显改善;经过1 365℃固溶后疏松含量增加至0.21%(体积分数),接近铸态下疏松含量的5.2倍。铸态及经1 360℃和1 365℃固溶热处理后合金的持久性能测试结果显示:固溶热处理显著改善了合金的持久性能,且固溶温度越高,持久性能越高。在高温持久加载过程中,铸态合金的裂纹主要沿枝晶间分布,在(γ+γ′)共晶组织处萌生;当固溶温度较低时,且枝晶干处析出了较多的TCP(topologically close-packed)相,未能充分降低Re元素的偏析可能是导致枝晶干处TCP相大量析出的主要原因;当固溶温度较高时,TCP相析出量较少。

Anisotropic and temperature-dependent growth mechanism of S-phase precipitates in Al-Cu-Mg alloy in relation with GPB zones

引用

Transactions of Nonferrous Metals Society of China 2016年第1期26卷 1-11页

作者：尹美杰陈江华王双宝刘自然茶丽梅段石云伍翠兰湖南大学材料科学与工程学院长沙410082

By employing atomic-resolution imaging and first principles energy calculations, the growth behavior of S-phase precipitates in a high strength A1-Cu-Mg alloy was investigated. It is demonstrated that the nucleation and growth of the S-phase precipitate are rather anisotropic and temperature-dependent companying with low dimensional phase transformation. There are actually two types of Guinier-Preston （GP） zones that determine the formation mechanism of S-phase at high aging temperatures higher than 180 ℃. One is the precursors of the S-phase itself, the other is the structural units or the precursors of the well-known Guinier-Preston-Bagaryatsky （GPB） zones. At high temperatures the later GPB zone units may form around S-phase precipitate and cease its growth in the width direction, leading to the formation of rod-like S-phase crystals; whereas at low temperatures the S-phase precipitates develop without the interference with GPB zones, resulting in S-phase orecioitates with lath-like momhology.

A three-dimensional numerical study on instability of sinusoidal flame induced by multiple shock waves

引用

Acta Mechanica Sinica 2017年第2期33卷 316-326页

作者： Xiao chen Gang Dong hua jiang Key Laboratory of Transient Physics Nanjing University of Science and Technology Nanjing 210094 China

The instabilities of a three-dimensional sinusoidally premixed flame induced by an incident shock wave with Mach = 1.7 and its reshock waves were studied by using the Navier-Stokes (NS) equations with a single-step chemical reaction and a high resolution, 9th-order weighted essentially non-oscillatory scheme. The computational results were validated by the grid independence test and the experimental results in the literature. The computational results show that after the passage of incident shock wave the flame interface develops in symmetric structure accompanied by large-scale transverse vortex structures. After the interactions by successive reshock waves, the flame interface is gradually destabilized and broken up, and the large-scale vortex structures are gradually transformed into small-scale vortex structures. The small-scale vortices tend to be isotropic later. The results also reveal that the evolution of the flame interface is affected by both mixing process and chemical reaction. In order to identify the relationship between the mixing and the chemical reaction, a dimensionless parameter, , that is defined as the ratio of mixing time scale to chemical reaction time scale, is introduced. It is found that at each interaction stage the effect of chemical reaction is enhanced with time. The enhanced effect of chemical reaction at the interaction stage by incident shock wave is greater than that at the interaction stages by reshock waves. The result suggests that the parameter can reasonably character the features of flame interface development induced by the multiple shock waves.
