人类社会的正常运转非常依赖化石能源,然而化石能源的消耗已导致能源危机和环境污染,同时空气中CO_(2)的含量从工业革命以来一直攀升。将CO_(2)通过催化反应转化为高附加值的燃料和化学品,不仅可以缓解环境问题,还开辟了一种燃料合成新路径,其中电催化CO_(2)还原技术由于条件温和、反应可控、对环境友好和产物众多受到广泛关注。电催化CO_(2)技术有四个关键步骤:(1)电荷传输(电子从导电基底传输到电催化剂);(2)表面转化(CO_(2)吸附在催化剂表面并被活化);(3)电荷传输(电子从催化剂表面传输到CO_(2)中间体);(4)传质效应(CO_(2)从电解质扩散到催化剂表面,产物以反向路径扩散),前两个步骤依赖于具有丰富有效活性位点的催化剂,后两个步骤依赖于电解质的性质、隔膜的类型和电解池的配置。本文从工业化和商业化电催化CO_(2)技术出发,系统地归纳催化剂的发展、电解液的影响、反应器的进展和隔膜的类型,最后对电催化CO_(2)还原的产业化进行展望。

目的探究二肽基肽酶-4抑制剂(dipeptidyl peptidase-4 inhibitors,DPP-4i)维格列汀改善糖尿病诱导心肌细胞的炎性损伤作用机制。方法体外培养AC16心肌细胞随机分为空白组、棕榈酸(palmitic acid,PA)组、0.1、1、10μmol·L^(-1)维格列汀组以及西格列汀组(阳性对照组)。采用CCK-8试剂盒检测细胞存活率;Western blotting检测目的蛋白DPP-4、p-NF-κB、IκB的表达情况;ELISA试剂盒检测炎症因子TNF-α和IL-6表达水平;TUNEL试剂盒检测细胞凋亡情况。结果AC16人源心肌细胞经PA处理后,细胞形态改变;CCK-8结果显示细胞存活率下降;Western blotting结果显示NF-κB磷酸化增强,且DPP-4蛋白表达升高;ELISA结果显示炎症因子TNF-α和IL-6表达水平上升;TUNEL阳性比例增多,促进心肌细胞凋亡。维格列汀给药后能有效抑制PA诱导的DPP-4蛋白异常表达,改善心肌细胞形态,并下调NF-κB磷酸化水平。ELISA结果显示维格列汀改善PA诱导的炎症因子TNF-α和IL-6表达水平上升,降低TUNEL阳性比例(P<0.05)。结论维格列汀可以有效拮抗PA诱导的心肌细胞炎性损伤,通过抑制NF-κB磷酸化水平,降低胞内炎症因子表达水平与抑制细胞凋亡,从而拮抗糖尿病心肌病诱导的心肌损伤。
