The change in the quantity of cultivated land influences the structure, function and evolvement of ecosystem. The rational change in the quantity of cultivated land will be propitious to ecological security and sustainable development, and irrational change will deteriorate ecological environment. The concept of cultivated land quantity niche regulation was firstly put forward based on niche theory and the action-feedback mechanism between cultivated land quantity niche and cultivated land benefit niche. Then, the regulation measures of cultivated land quantity niche were brought forward in rural-urban area, agro-forest area and consolidation-reclamation-exploitation area. Finally, the ecological environmental effect after regulation was analyzed. The results show that different measures should be taken to regulate cultivated land quantity niche in different areas. The economic and social benefit niche of cultivated land should be promoted to regulate cultivated land quantity niche in rural-urban area and consolidation-reclamation-exploitation area. The social benefit niche of cultivated land should be reduced in agro-forest area. The regulation goal of cultivated land quantity niche will be attained by different measures.

Lysosome-targeted carbon dots with a light-controlled nitric oxide releasing property for enhanced photodynamic therapy

Chinese Chemical Letters 2024年第4期35卷 420-425页

作者： Hao Cai Xiaoyan wu Lei jiang Feng Yu Yuxiang Yang Yan Li Xian Zhang jian Liu Zijian Li Hong Bi school of Materials science and engineering Anhui UniversityHefei 230601China school of Chemistry and Chemical engineering Anhui UniversityHefei 230601China school of Food and Biological engineering Hefei University of TechnologyHefei 230009China

The reactive oxygen species(ROS) generation efficiency is always limited by the extreme tumor microenvironment(TME), leading to unsatisfactory antitumor effects in photodynamic therapy(PDT). As a promising gas therapy molecule, nitric oxide(NO) is independent of oxygen and could even synergize ROS to enhance the therapeutic effect. However, the short half-life, instability, and uncontrollable release of exogenous NO limited the application of tumor synergistic therapy. Herein, we reported a novel kind of red-emissive carbon dots(CDs) that was capable of lysosome-targeted and light-controlled NO delivery. The CDs were synthesized by using metformin and methylene blue(MB) via a hydrothermal *** obtained metformin-MB CDs(MMCDs) exhibited a higher1O2quantum yield and NO generation efficiency under light emitting diode(LED) light irradiation. Noteworthily, the1O2could further in situ oxidize NO into peroxynitrite anions(ONOO-), which own the higher cytotoxicity against cancer *** experiments indicate that MMCDs could destruct lysosome membrane integrity and kill almost 80%of Hep G2 cells under light irradiation while very low cytotoxicity in the dark. Moreover, MMCDs significantly decreased tumor volume and weight after phototherapy in hepatoma Hep G2-bearing mice. Our study provides a new strategy for light-controlled NO generation as well as precise lysosome-targeting for enhancement of PDT efficiency.
