农户是农村人居环境的缔造者和受益者,其参与的积极性和主动性是顺利推进农村人居环境整治的重要保障。基于感知价值和刺激—机体—反应(SOR)理论模型,从社会资本和感知价值双重视角构建农户参与农村人居环境整治意愿的理论分析框架,并结合江西省农户调研数据进行实证检验。结果表明:(1)社会网络、社会信任及社会规范对农户参与意愿均产生显著正向影响,其中社会网络效应最大;功能价值、情感价值及认知价值对农户参与意愿均产生显著正向影响,其中功能价值效应最大。(2)社会网络显著影响功能价值、情感价值及认知价值水平。表明社会网络是影响农户感知价值最为关键的因素。(3)感知价值在社会资本对农户参与农村人居环境整治意愿的影响过程中起到部分中介作用。据此,在推动农村人居环境整治过程中,要大力培育农户的社会资本,提高农户对农村人居环境整治的感知价值水平,进而提高农户参与农村人居环境整治的积极性。

为恰当使用木醋液增产,盆栽和大田种植甘蓝型油菜杂交品种华油杂9号,调查木醋液不同叶面喷施次数、不同施用间隔时间以及不同播期条件下,木醋液对油菜生长与产量的影响。盆栽结果表明,连续和间隔喷施2~4次的木醋液显著提高油菜的总干重29.63%~74.07%。同时连续与间隔喷施4次的木醋液可显著提高油菜的叶面积81.58%~85.65%。大田试验结果表明,苗期、蕾薹期、花期分别喷施1次、2次、3次处理的油菜,最终籽粒产量分别显著提高3.30%、9.52%、11.38%,蛋白含量分别降低2.62%、4.02%、4.68%。3个不同播期喷施木醋液处理的大田产量较对照分别显著提高20.13%、23.25%、13.97%,单株有效角果数分别提高47.29%、61.87%、72.90%。综合分析表明,在油菜生长期间喷施木醋液2~4次,每次间隔5 d以上的促进效果更好。不同播期条件下,木醋液对油菜生长与产量的影响以适期(即10月9日)播种效应更显著。

目的:探究王不留行黄酮苷(VAC)对2型糖尿病(T2DM)内皮功能障碍的治疗作用及机制研究。方法:(1)通过腹腔注射链脲佐菌素和喂饲高脂饲料(21.8 kJ/kg,60%能量为脂肪)构建T2DM小鼠模型。将30只C57BL/6小鼠随机分为对照组、T2DM组和T2DM+VAC组,每组10只。T2DM+VAC组小鼠给予1 mg/kg VAC灌胃6周,对照组和T2DM组小鼠均给予等体积PBS。RT-qPCR和Western blot检测胸主动脉中BCL2相互作用蛋白3(BINIP3)、PTEN诱导激酶1(PINK1)和parkin的mRNA和蛋白表达。(2)在体外通过高糖(HG)刺激人脐静脉内皮细胞(HUVECs),用JC-1染色检测线粒体膜电位变化,吖啶橙(AO)染色检测自噬溶酶体变化,MitoSOX染色检测线粒体超氧化物的积累。结果:与对照组相比,T2DM小鼠胸主动脉BNIP3、PINK1和parkin的mRNA和蛋白表达水平显著升高(P<0.05);与T2DM组相比,T2DM+VAC组小鼠胸主动脉中BNIP3、PINK1和parkin的mRNA和蛋白表达水平显著降低(P<0.05)。JC-1、AO和MitoSOX染色结果显示,VAC可抑制HG诱导的HUVECs线粒体膜电位降低、自噬溶酶体增多和线粒体超氧化物水平升高。VAC也可减轻BNIP3过表达后HG诱导的HUVECs线粒体损伤。微小RNA-570-3p(miR-570-3p) mimic与VAC有相似的减轻线粒体损伤作用。RT-qPCR和Western blot结果显示,miR-570-3p mimic和VAC都使BNIP3、PINK1和parkin的mRNA和蛋白水平显著降低。使用miR-570-3p抑制剂后,VAC的上述作用均被抑制。结论:VAC通过miR-570-3p/BNIP3减轻HG诱导的线粒体损伤,从而缓解T2DM内皮功能障碍。
