农民教育政策体系对于处理农民教育公共问题以解决农民发展问题具有重要作用,农民教育的最终目的指向全体农民物质与精神的共同富裕。本文立足于马克思主义关于人的全面发展理论的基本立场与研究方法论,建构起农民教育政策体系的“四维一体”理论分析框架,并基于对2.0份农民教育政策的文本分析和49位农民教育政策体系利益相关主体的深度访谈,就中国式现代化进程中的农民教育政策体系优化问题进行解构。本文研究发现:中国农民教育政策体系面临农民教育政策观念“短板视角”主导、农民教育政策主体格局碎片化、农民教育政策内容结构供需错位、农民教育政策过程有效性不足等现实问题,进而引发农民发展的内生动力不足、农民发展的保障机制存在缺陷、农民发展的片面性倾向较明显、农民发展的终身性乏力等困境。因此,面向农业强国的农民教育政策体系优化应在农民教育政策观念上更加强调农民主体性、在农民教育政策主体上更加重视整体性建设、在农民教育政策内容上更加突出需求导向、在农民教育政策过程上更加关注全生命周期,通过聚焦农民主体性培育、构建“大农民教育”工作格局、健全农民终身教育体系、完善农民教育评价体制机制等途径,实现全面发展视域下的农民教育政策体系优化由理念向实践的转化。

生物学中究竟有无定律一直是个充满争议的话题。最近,有学者试图表明生态学中的“异速生长模型”可以被视为定律,而反对者则基于约翰·比蒂的“进化偶然性论题”对其提出了挑战。这一挑战指出,异速生长模型可以被还原为几何学和物理学定律,因而它们不能被视为生物学定律。对它的一种回应是,在异速生长模型还原为物理学定律的过程中,作为“桥接定律”的生物物理学概括可能成为生物学定律。然而,对该回应的分析表明,其中的生物物理学概括是否存在还有待证明;即使可能存在,它们也是充满例外的偶适概括,仍会遭遇进化偶然性论题的挑战。因而,异速生长模型不能被视为生物学定律。

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer(LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha(FAPα) expression in LNM-CRC cells. Gain-or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis(CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.
