施用磷肥是提高作物产量、维护国家粮食安全的重要保障。磷矿是不可再生资源，如何在当前磷矿质量和数量均下降的条件下，通过磷肥产品创新来大幅度提高磷肥利用率就变得尤为重要。回顾磷肥产品的诞生与我国磷肥工业的发展脉络，讨论我国主要土壤-作物体系中磷肥施用普遍存在的问题，进一步针对磷资源枯竭和磷肥施用不当引起的问题提出新型磷肥的创制思路与实现途径，包括作物-土壤体系专用磷肥、新型超移动磷肥、磷矿有益元素全量利用磷肥、原位螯合磷肥、有机磷肥。

苦味受体/2型味觉受体(type 2 taste receptors,T2Rs)是一类G蛋白偶联受体,最初在味蕾细胞中被发现,现已证实在多种组织中表达并发挥功能。本文重点探讨了T2Rs在巨噬细胞中的表达水平、分布特征,以及T2Rs激动剂调节巨噬细胞的功能和作用机制,包括增强吞噬作用、诱导趋化性定向运动和调节巨噬细胞极化等,可能涉及NF-κB、PI3K/Akt和JAK/STAT等通路,但仍需更多数据支撑。T2Rs对巨噬细胞的调控作用虽已初显,但T2Rs亚型的作用规律尚不明晰。未来研究可从明确T2Rs亚型与巨噬细胞特定功能的对应关系、探究其调节巨噬细胞的具体分子机制、揭示在疾病进程中的详细机制等角度深入,为开发以T2Rs为靶点的新型药物奠定基础。

本文主要基于“一气周流，土枢四象”理论与临床实践的结合，探讨“一气周流，土枢四象”在黄斑水肿临床上的应用。通过整理医案，阅读相关古籍、文献，深入探讨“一气周流，土枢四象”理论在黄斑水肿的发生、发展以及治疗中的应用。笔者团队认为黄斑水肿的发生，究其源头，当责之于脾胃中气枢纽的异常，脾胃枢纽异常，则肝、心、肺、肾四象运转不利，并在此过程中出现痰、湿、瘀等病理产物，进一步影响中土、四象的正常功能。故而在治疗上，提出了以顾护中土为基础，重视调护四象气机升降的流畅，并兼顾祛除病理产物的思路，取得了较好的临床疗效。故本文通过总结临床经验，并基于“一气周流，土枢四象”理论对黄斑水肿的病机、治疗进行讨论，以期为临床治疗眼底病提供更多思路。
