全面小康后我国进入“后扶贫时代”,数字金融的使用对缓解多维贫困具有重要价值。采用CHFS2019年数据,研究数字金融对农户多维贫困的影响机理及其异质性。研究显示,数字金融能有效缓解农户多维贫困,金融能力的提升是重要应用机制。具体而言,数字金融对“收入能力贫困”这一维度的影响效应最大,网购这种数字金融使用行为对农户多维贫困的影响最大。异质性分析表明,数字金融减贫效应在空间和个体上均存在“数字鸿沟”。据此建议完善数字金融基础设施和积极推广引导农户使用数字金融技术,最后需要加强金融监管,尽量消除其负面影响。

Neural Regeneration Research 2018年第11期13卷 1893-1899页

Myelin-associated glycoprotein（MAG） inhibits the growth of neurites from nerve cells. Extraction and purification of MAG require complex operations; therefore, we attempted to determine whether commercially available MAG-Fc can replace endogenous MAG for research purposes. Immunofluorescence using specific antibodies against MAG, Nogo receptor（NgR） and paired immunoglobulin-like receptor B（PirB） was used to determine whether MAG-Fc can be endocytosed by neuro-2a cells. In addition, neurite outgrowth of neuro-2a cells treated with different doses of MAG-Fc was evaluated. Enzyme linked immunosorbent assays were used to measure RhoA activity. Western blot assays were conducted to assess Rho-associated protein kinase（ROCK） phosphorylation. Neuro-2a cells expressed NgR and PirB, and MAG-Fc could be endocytosed by binding to NgR and PirB. This activated intracellular signaling pathways to increase RhoA activity and ROCK phosphorylation, ultimately inhibiting neurite outgrowth. These findings not only verify that MAG-Fc can inhibit the growth of neural neurites by activating RhoA signaling pathways, similarly to endogenous MAG, but also clearly demonstrate that commercial MAG-Fc is suitable for experimental studies of neurite outgrowth.
