目的:观察猪肺磷脂注射液联合高频通气模式治疗新生儿呼吸窘迫综合征(NRDS)的应用效果。方法:选择2020年4月~2022年4月在院收治的60例NRDS患儿作为研究对象,采用随机数字表法将患者分为两组,对照组(30例)采用猪肺磷脂注射液联合间歇指令机械通气治疗,研究组(30例)采用猪肺磷脂注射液联合高频震荡通气治疗,比较两组患者的临床疗效、血气分析及呼吸力学指标、临床效果和合并症。结果:治疗后,治疗组与对照组相比,治疗组的总治疗有效率为96.67%。结果:实验组动脉血氧分压(PaO_(2))、血氧饱和(SpO_(2))明显升高,而血管内CO_(2)(PaCO_(2))浓度则明显降低。研究组患者平均气道阻力、呼出潮气量及动态顺应性明显高于对照组。研究组患者氧疗时间、机械通气时间及住院时间低于对照组。两组患者并发症总发生率无明显差异。结论:猪肺磷脂注射液联合高频振荡通气可明显提高NRDS患儿的疗效,并能有改善患儿的血气功能与呼吸功能指标,促进患儿康复,安全性及临床应用价值均较高。

Hepatic ischemia-reperfusion injury（HIRI） is characterized by mitochondrial dysfunction and oxidative stress. Monitoring mitochondrial hydrogen peroxide（mtH2O2） levels in real-time through super-resolution imaging is crucial for elucidating its distribution in live cells and its mechanism of action during HIRI. However, low-background fluorogenic probes have been overlooked in the context of super-resolution imaging. In this study, we developed a low-background fluorogenic probe（MitoWG） with the potential for super-resolution morphology-correlated mitochondrial identification to track the fluctuates of mtH2O2in HIRI. Activation of the desirable fluorescence properties of the probe by mtH2O2was confirmed using structural illumination microscopy（SIM）, enabling high-quality mitochondrial imaging with exceptional specificity and *** in mtH2O2levels were successfully observed in both cellular and rat models of HIRI. Furthermore, we associated the decline in mitochondrial redox homeostasis with accelerated mtH2O2production during HIRI, which triggered mitophagy deficiency and led to cell death. In conclusion, Mito-WG possesses excellent photophysical and low-background properties for SIM imaging, making it a promising tool for mtH2O2tracking in HIRI research and clinical diagnosis.

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.
