Silver-containing preparations are widely used in the management of skin wounds, but the effects of silver ions on skin wound healing remain poorly understood. This study investigated the effects of silver ions (Ag+) on the proliferation of human skin keratinocytes (HaCaT) and the production of intracellular reactive oxygen species (ROS). After treating HaCaT cells with Ag+and/or the active oxygen scavenger N-acetyl cysteine (NAC), cell proliferation and intracellular ROS generation were assessed using CCK-8 reagent and DCFH-DA fluorescent probe, respectively. In addition, 5-bromo-2-deoxyUridine (BrdU) incorporation assays, cell cycle flow cytometry, and proliferating cell nuclear antigen (PCNA) immunocytochemistry were conducted to further evaluate the effects of sub-cytotoxic Ag+ concentrations on HaCaT cells. The proliferation of HaCaT cells was promoted in the presence of 10−6 and 10−5 mol/L Ag+ at 24, 48, and 72 h. Intracellular ROS generation also significantly increased for 5–60 min after exposure to Ag+. The number of BrdU-positive cells and the presence of PCNA in HaCaT cells increased 48 h after the addition of 10−6 and 10−5 mol/L Ag+, with 10−5 mol/L Ag+ markedly increasing the cell proliferation index. These effects of sub-cytotoxic Ag+ concentrations were repressed by 5 mmol/L NAC. Our results suggest that sub-cytotoxic Ag+ concentrations promote the proliferation of human keratinocytes and might be associated with a moderate increase in intracellular ROS levels. This study provides important experimental evidence for developing novel silver-based wound agents or dressings with few or no cytotoxicity.

把我国广大的沙化草原建设成为可再生的世界级特大的清洁能源生产基地

中国有广大的约占国土面积40 %的沙化退化草原,不宜亦没有用作粮食耕地。但经过大力的生态建设后每年能产出巨量的巨银草。后者是原生在中国北部,能耐干寒和恶劣环境,并是多年生高达3.5 m的巨大稠密的野草,并能利用咸水。将这些巨银草气化催化后估计每公顷可产出17.2 t的可直接替代汽油的生物丁醇,生化和基因研发专业公司孟山都和孟代尔等己开始合力提升此产能,估计到2030年左右,以沙化草原的约46 %的面积种植巨量的巨银草,可使中国开始不再依赖石油和煤炭的化石能源,而转用由巨大的“巨银草油田群”供应的可再生的清洁能源,其余的面积的产量可供外销或作他用,使中国能长期成为世界能源强国,与他国合力稳定能源供应和价格,并引领世界迈向可再生的清洁能源新时代。
