科技金融、绿色金融是金融强国建设的重要组成部分,也是业界关注的重点。企业ESG(环境、社会和公司治理)行为对推动可持续投资和实现“双碳”目标、促进传统产业转型升级、助力经济高质量发展具有重要意义,其内涵与科技金融、绿色金融的发展要求不谋而合。本文以2010—2021年A股上市公司为研究样本,考察企业ESG表现如何影响绿色金融科技发展。研究结果显示,首先,积极改善企业ESG表现能显著提升绿色金融科技发展水平。其次,信息透明度在ESG改善绿色金融科技的影响中具有“遮掩效应”。最后,企业ESG表现对绿色金融科技发展的影响在产权性质、股权制衡度和信息环境等方面存在异质性。本文拓展了关于企业ESG经济后果的研究范畴,深化了企业ESG表现对金融科技发展影响的理解,为促进绿色金融科技的平稳发展提供了新的思路。

Donkey whey proteins ameliorate dextran sulfate sodium-induced ulcerative colitis in mice by downregulating the S100A8-TRAF6-NF-κB axis-mediated inflammatory response

Donkey milk has a variety of physiological functions, including antibacterial and anti-inflammatory. Donkey whey proteins(DWPs), as the main functional component in donkey milk, its inhibitory effect on colitis is still unclear. In this study, the inhibitory effect and potential mechanism of DWPs on dextran sulfate sodium(DSS)-induced colitis were investigated. Firstly, the DWPs and bovine milk whey proteins(BWPs)were characterized using proteomics. Then, we administered DWPs and BWPs to mice with colitis via oral gavage. The results of immunohistochemistry and flow cytometry indicated that DWPs increased T regulatory cell accumulation and increased the abundance of the cluster of differentiation 205+(CD205+)macrophages compared to those with BWPs and in model groups. In addition, DWPs exhibited a more remarkable ability to inhibit pro-inflammatory proteins(S100A8, TRAF6, and NF-κB)expression and inflammatory secretion than BWPs. In addition, DWPs significantly decreased NF-κB and CD86 levels more than BWPs or the negative control in both LPS-stimulated human peripheral blood mononuclear cells or cell lines. These findings indicate that DWPs comprise a promising anti-colitis functional food, and this work has established a foundation for future research on these compounds.
