Triggering receptor expressed on myeloid cells-1 (TREM-1) is a member of the immunoglobulin superfamily. As an amplifier of the inflammatory response, TREM-1 is mainly involved in the production of inflammatory mediators and the regulation of cell survival. TREM-1 has been studied in infectious diseases and more recently in non-infectious disorders. More and more studies have shown that TREM-1 plays an important pathogenic role in kidney diseases. There is evidence that TREM-1 can not only be used as a biomarker for diagnosis of disease but also as a potential therapeutic target to guide the development of novel therapeutic agents for kidney disease. This review summarized molecular biology of TREM-1 and its signaling pathways as well as immune response in the progress of acute kidney injury, renal fibrosis, diabetic nephropathy, immune nephropathy, and renal cell carcinoma.

Non-alcoholic fatty liver disease (NAFLD) has become a global issue and a severe threat to public ***, to date, no approved therapeutic drugs have been developed. Dietary interventions with naturalproducts have shown promise in preventing and treating NAFLD. Sulforaphane (SFN) is a phytocompoundwith antioxidant and anti-inflammatory properties, and previous research has demonstrated that SFN canameliorate hepatic lipid accumulation and inflammation. However, the molecular mechanisms underlying thesebeneficial effects remain unclear. In this study, we confirmed the protective effects of SFN on excessive lipidaccumulation and inflammatory injury in a high-fat, high-fructose diet-induced non-alcoholic steatohepatitis(NASH) mouse model. We found that SFN attenuates the inflammatory injury in a macrophage cell line andthe liver of NASH mice, owing to the promotion of M1-type macrophage polarization toward the M2-type andthe regulation of inflammatory mediators. Further analysis demonstrated that this SFN-induced macrophageM2-type polarization occurs in a Krüppel-like factor 4 (KLF4)-dependent manner. In summary, we uncovereda new mechanism of action underlying SFN activity and provide evidence that dietary intervention with SFNmight be protective against NASH.

针对光伏出力的随机性和波动性导致预测精度偏低的问题,构建一套融合相似日理论、变分模态分解法、模糊熵计算方法和深度学习算法的光伏出力组合预测模型。在运用灰色关联分析法确定影响光伏出力的关键气象因素和使用综合相似距离法选定待预测日的历史相似日的基础上,利用模糊熵对变分模态分解的光伏出力分量进行重组,得到若干规律性较强的新序列;然后,分别构建各重组序列的长短期记忆神经网络预测模型;最终,对重组序列的预测值进行求和得到预测结果。该组合模型在云南某光伏电站的应用结果表明,对比其他模型,所提出的组合预测模型精度更高,具有很好的应用前景。

学校文化建设是我国文化强国战略的重要组成部分。当前,我国学校文化建设正遭遇着由系统殖民引起的离境之忧、主体中心逻辑造就的生成之困和从“成人”到“治人”的体用之殇。哈贝马斯交往行动理论为重塑学校文化生态提供了有益启示。其主要观点将以语言为媒介的交互活动作为系统进化的动力源泉,将“U”“D”原则作为系统优化的外部保障,将“非强迫共识”作为系统规范的本质属性。基于此提出我国学校文化建设的变革路径,要强化其底层逻辑,完善其对话规则,遵循其人本指向。
