In the current context of vigorously promoting the construction of ecological civilization, land consolidation in the construction of the constant pursuit of ecological design, to achieve sustainable use of land resources, China has made great progress in ecological land consolidation. In this paper, through the comparison of flow design and cross section design of agricultural canal design in ecological land remediation and traditional land remediation, the characteristic design of some agricultural canals in ecological land remediation was introduced, and the ecological, social and economic benefits of two land remediation methods were systematically analyzed. The analysis shows that ecological agricultural canals play a great role in protecting biodiversity, alleviating the contradiction between people and land, saving energy, purifying water resources and improving land quality, the research result has provided the basis and the model for the land consolidation in carrying on the ecology type ditch design.

The remediation of inefficient garden land and defective forest land is one of the important sources and types of supplementary cultivated land in the comprehensive land remediation of the whole region. The remediation and development of inefficient garden land and defective forest land will effectively alleviate the multiple pressures faced by cultivated land at present. Taking Zhemu Town, Guilin City, China as an example, on that basis of the data of the third national land survey, using analytic hierarchy process, this paper selects six evaluation factors, including water source, traffic, slope, field concentration, farmland infrastructure and villagers’ will, to study the remediation potential of inefficient garden land and defective forest land in Zhemu Town, and delimits four potential divisions, in order to provide the basis for the arrangement of land remediation projects in Zhemu Town. The results show that the northern, central and western regions of Zhemu Town have great remediation potential.

炎症性肠病(IBD)分为溃疡性结肠炎和克罗恩病,是一种与免疫功能紊乱密切相关的慢性复发性炎症性胃肠道疾病。IBD的发病机制与遗传易感性、免疫功能障碍、环境改变和肠道微生物群紊乱密切相关。现代研究发现,巨噬细胞极化在IBD发生发展中占有重要地位,能够影响炎症反应水平、肠道黏膜修复及肠道微生物群平衡等,是治疗IBD的潜在靶点。越来越多的研究表明,中药及其有效成分能够通过多途径调节巨噬细胞极化,平衡M1/M2巨噬细胞比率,从而抑制炎症反应,促进肠黏膜修复,减缓IBD的进一步发展。该文通过总结巨噬细胞极化的生物学过程与涉及靶点,详述其在IBD中的影响。同时对中药及其有效成分能够通过调控巨噬细胞极化改善IBD的最新研究作简要综述,以期为中医药治疗IBD更好应用于临床提供新方向与新策略。

In recent years, with the rapid development of urbanization in China, land acquisition work is particularly important. The division of expropriated area is the primary factor to be considered when evaluating the comprehensive land price of expropriated area. Reasonable division can help to improve the scientific and applicability of the comprehensive land price of the region. How to maximize the protection of farmers’ rights and interests by the division of land requisition is an urgent problem to be solved. Taking Gongcheng Yao Autonomous County as an example, this study adopted the multi-factor comprehensive evaluation method to evaluate the division of land requisition in this area, and carried out the corresponding spatial analysis and data processing based on GIS technology. Gongcheng Yao Autonomous County was divided into levy areas, and the Delphi method was used to screen the impact factors and determine the weight of the levy areas. Reasonable division of land requisition area can provide references for land requisition area, make it more scientific and reasonable, and protect the rights and interests of farmers.

背景:骨关节炎是一种慢性骨骼肌肉退变性疾病,发病率呈现逐年增加的趋势,但是其发病机制尚未明确。常用的药物有非类固醇类抗炎药、糖皮质激素等,但此类药物的不良反应会降低患者的依从性,因此最终影响了治疗效果,而中药有效成分因具备安全性等特点被研究者们所密切关注。目的:综述近些年中药有效成分对于骨关节炎相关信号通路影响的研究进展,为防治骨关节炎的新药研发、基础研究以及临床应用提供思路和理论依据。方法:通过检索中国知网、万方、维普、PubMed、GeenMedical等数据库,检索近十年相关文献,以“骨关节炎、中药、中药成分、软骨细胞、炎症、信号通路、作用机制”“OA、Chinese traditional medicine、active ingredients of traditional Chinese medicine、Chondrocyte、Inflammation、Signal pathways、Mechanism”等作为检索词进行检索,排除无关重复且年代较久的文献,最终筛选63篇文献进行探究。结果与结论:中药有效成分主要通过Wnt/β-catenin、NK-κB、P38 MAPK、PI3K/Akt、JAK2/STAT3等信号通路调节相关炎症因子的水平,促进软骨细胞的增殖分化,调控软骨细胞凋亡,延缓软骨细胞退变,从而减缓骨关节炎病情的进展。
