目的了解姜黄素对哮喘小鼠气道高反应性及气道炎症的影响.方法对30只Balb/c小鼠随机分为正常对照组、哮喘组及姜黄素干预哮喘小鼠.应用OVA溶液建立哮喘小鼠模型;对各组小鼠进行肺功能的检测;应用Giemsa染色测定各组小鼠支气管肺泡灌洗液的炎症细胞计数;HE染色及PAS染色对各组小鼠行肺组织病理学检测;ELISA方法检测各组小鼠支气管肺泡灌洗液中的IgE含量.结果哮喘组小鼠在吸入乙酰甲胆碱(Mch)6.25 g/L浓度后,Penh值显著高于正常对照组,两组比较差异有统计学意义(P＜0.01),而姜黄素干预哮喘组较哮喘组明显降低,两组比较差异有统计学意义(P＜0.01).哮喘组小鼠气道盥洗液白细胞总数及嗜酸细胞数显著高于正常对照组,两者比较差异统计学意义(P＜0.01),而姜黄素干预哮喘组白细胞及嗜酸细胞数量明显较哮喘组减少,两者比较有差异有统计学意义(P＜0.01).哮喘组小鼠中BALF的IgE含量较对照组明显升高,两组比较差异有统计学意义(P＜0.01);而姜黄素干预哮喘组中BALF的IgE含量较哮喘组明显降低(P＜0.01).哮喘小鼠肺组织HE染色中可见支气管和血管壁周围有大量的炎性细胞浸润,以嗜酸细胞和淋巴细胞浸润为主,姜黄素干预哮喘组较其减少.PAS染色哮喘组小鼠杯状细胞、黏液分泌明显增多,姜黄素干预哮喘组较其减少.结论姜黄素可以减轻哮喘小鼠的气道炎症,减轻气道黏液分泌、降低气道高反应性、降低肺泡灌洗液中的IgE含量.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

A lightweight road-assistant detection algorithm， EBD-YOLO， based on YOLOv5s is proposed to address the problems of high model complexity， computation cost， and difficulty in deployment on resource-limited embedded terminals in existing assisted driving detection algorithms. First， lightweight Transformer model EfficientViT was used as the backbone feature extraction network of YOLOv5s model to reduce network parameters and calculation costs. Secondly， a Focal-GIoU Loss function is proposed for bounding box regression to accelerate model convergence and reduce loss. Thirdly， the feature pyramid structure is improved to a weighted bi-directional feature pyramid network (BiFPN) to enhance localization and semantic features. Then， a dynamic head framework is added to unify the attention mechanism with the object detection head to improve its performance. Finally， a Soft-CIoU＿NMS algorithm is proposed in the post-processing stage to enhance occluded targets' localization and detection ability and reduce the missed detection rate. We conducted experiments on the KITTI and BDD100K datasets for autonomous driving， and the results showed that the EBD-YOLO model reduced in size by 38.4% and 37.2%， respectively. In comparison， the computational cost was reduced by 48.1%. As measured by mAP@0.5， the detection accuracy improved by 0.5% and 5.8%， respectively， and mAP@0.5:0.95 improved by 2.8% and 7%， respectively. These improvements satisfied the requirements for deployment on embedded terminals in cars.
