目的:探索阿昔洛韦(ACV)对体外培养人眼Tenon囊成纤维细胞(HTFs)的增殖和凋亡的影响以及作用机制。方法:将HTFs分为ACV处理组和空白组;CCK8检测不同浓度梯度下的细胞增殖速率,划痕实验检测HTFs迁移能力,流式细胞术检测HTFs凋亡以及细胞周期。结果:与空白组相比,ACV处理组(终浓度分别为1.125、2.25、3.375、4.5mmol/L)HTFs增殖速率显著降低(P<0.05),且呈浓度依赖性。4.5mmol/L ACV处理组划痕细胞迁移率显著降低(P<0.05),细胞凋亡率显著增加(P=0.0005),细胞周期G0/G1期峰值升高(P=0.0011),S期下降(P=0.0006),细胞周期被阻滞在G0/G1期。结论:阿昔洛韦可以通过阻滞HTFs周期促进细胞凋亡,抑制HTFs的增殖和迁移。

继发于病理性近视的脉络膜新生血管(choroidal neovascularization,CNV)是造成不可逆中心视力丧失的常见原因,发病率高且严重影响患者的生活质量。传统治疗模式包括热激光光凝术、经瞳孔热疗法以及使用维替泊芬的光动力学疗法。但是,这些治疗方法的长期结果不容乐观。而玻璃体内注射抗VEGF的治疗能够比传统方式更有效地提高视力,减少中央视网膜厚度。因此,这些抗VEGF药物有可能成为治疗继发于病理性近视CNV的一线药物。本综述通过讨论近视CNV的发病机制,抗VEGF药物的分子结构和作用机制,比较抗VEGF药物对继发于病理性近视CNV的治疗功效和安全性。

外界能量通过贯通线进入开孔屏蔽体,与PCB上MSL耦合而生成感应电流(Current),加剧了对敏感器件的耦合伤害。故建立含贯通线及PCB板开孔屏蔽腔模型,进行多角度耦合特性计算。在建模有效性验证后,利用有限元法探讨平面波激励下PCB不同模型、MSL上不同端接电阻、贯通线半径、贯通线与腔体壁相接及多贯通线等参数变化对Current的影响规律。结果表明:双介质模型的使用更接近实际PCB结构对场的影响;两端接电阻取值相差不大条件下,可不考虑与MSL的阻抗匹配,取值也可不相等;Current数值随贯通线半径的增加而增加;贯通线与腔体壁不同表面相接对应Current幅值要远高于非接触的情况,并会激出新的谐振点。多根贯通线及线间距改变时Current幅值都要高于单线的情况,尤以第一谐振之前更为明显,多线存在不会影响谐振点出现位置。

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.
