BACKGROUND:Macrophages play a key role in the occurrence and progression of lung diseases,and autophagy plays an important role in maintaining environmental homeostasis and functional stability in macrophages.It has been suggested that macrophage autophagic activity has two sides in lung inflammatory diseases.OBJECTIVE:To summarize the relationship between macrophage autophagy and lung diseases,thereby providing reference for exploring the prevention and treatment strategies of lung inflammatory diseases by targeting macrophage autophagy.METHODS:Literature retrieval was performed in CNKI and PubMed for relevant literature published from database inception to September 2024.The search terms were"macrophage autophagy,efferocytosis,macrophage polarization,acute lung injury,pneumonia,chronic obstructive pulmonary disease,pulmonary fibrosis,asthma"in Chinese and English,respectively.The search results were included or excluded based on the selection criteria,and 100 papers that met the criteria were finally included in the review.RESULTS AND CONCLUSION:(1)The obstruction of autophagy flow will induce the polarization imbalance of macrophages and impair their efferocytosis,resulting in the increase of M1 macrophages and aggravating inflammation.(2)The judgment of autophagic activity should be based on whether the autophagy flow is smooth or not,and it is essential to evaluate the degradation ability of autophagy.Some studies failed to comprehensively detect the degradation ability of autophagy lysosomes to assess whether the autophagy flow is unobtrusive.As a result,the so-called two-sided view of pulmonary macrophage autophagy in pulmonary inflammatory diseases in such studies is actually related to the one-sided judgment of autophagy activity.(3)The pathological manifestations vary across different pulmonary diseases and even at different stages of the same disease.Activation of macrophage autophagy plays a positive role in regulating pulmonary inflammatory homeostasis in conditions such as acute lung injury,infectious pneumonia,mild chronic obstructive pulmonary disease,early-stage pulmonary fibrosis,and secondary asthma.However,in the severe fibrotic stage of chronic obstructive pulmonary disease and the progressive stage of pulmonary fibrosis,the activation of pulmonary macrophage autophagy aggravates pulmonary fibrosis,reflecting the dual nature of macrophage autophagy.In allergic asthma,autophagy is activated in lung-resident macrophages but suppressed in infiltrating monocyte-derived macrophages from circulation.The former is closely related to airway stenosis,and the latter aggravates pneumonia disorders.Therefore,identifying the types and progression stages of lung diseases,along with accurately assessing autophagic activity,is crucial for future investigations into the relationship between macrophage autophagy and disease pathogenesis,thereby facilitating the development of therapeutic strategies in the future.

Endothelial dysfunction induced by inflammation and oxidative stress represents a critical pathological mechanism in cardiovascular and cerebrovascular diseases, including sepsis and atherosclerosis. Although crebanine has been reported to possess antiinflammatory and analgesic properties, its effects on inflammation and oxidative stress in endothelial cells remain unknown. In this study, we assessed cell viability, apoptosis, and migration using the Cell Counting Kit-8 (CCK-8), flow cytometry, and a wound healing assay, respectively. The levels of reactive oxygen species (ROS) and the expression of inflammatory and oxidative stress markers were determined by qRT-PCR, enzyme-linked immunosorbent assay (ELISA), and Western blotting analysis. Our results demonstrated that crebanine alleviated lipopolysaccharide (LPS)-induced apoptosis and dysfunction in human umbilical vein endothelial cells (HUVECs). Crebanine treatment inhibited the production of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β), ROS, and malondialdehyde (MDA), while it enhanced the activity of the antioxidant enzyme superoxide dismutase (SOD). Mechanistically, crebanine suppressed LPS-induced activation of the NF-κB signaling pathway in HUVECs. Furthermore, the improvement effect of crebanine on the inflammation and dysfunction in LPS-treated HUVECs was reversed by diprovocim, an NF-κB activator.These findings suggest that crebanine ameliorates LPS-induced inflammation and oxidative stress in HUVECs by inhibiting the NF-κB signaling pathway, indicating its potential therapeutic value for treating vascular endothelial dysfunction-related diseases.

OBJECTIVE To optimize the extraction process of organic acids from Angelica sinensis using deep eutectic solvents (DESs), and conduct characterization, antioxidant activity evaluation, and extraction mechanism analysis. METHODS The conductor-like screening model for realistic solvation with segment activity coefficients (COSMO-SAC) was employed to screen the types of DESs. With total organic acid content as the response value, single-factor experiments and Box-Behnken response-surface methodology were used to optimize the extraction conditions. Using A. sinensis decoction pieces and/or A. sinensis methanol extract as references, scanning electron microscope and Fourier transform infrared spectrometer (FTIR) were applied to characterize the products. Additionally, the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6- sulfonic acid) (ABTS) free radical scavenging capacities were determined. Density functional theory (DFT) was used to analyze the extraction mechanism of ferulic acid and chlorogenic acid by the DESs. RESULTS & CONCLUSIONS The optimal DESs was choline chloride-propanediol. The optimal extraction conditions for organic acids from A. sinensis were as follows: choline chloride- propanediol molar ratio of 1∶1, DESs water content of 70%, solid-liquid ratio of 1∶10, heating temperature of 57 ℃, and heating and stirring time of 8 min. In three validation experiments, the total organic acid content was 2.92 mg/g, yielding a relative error of 0.34% compared to the predicted value (2.91 mg/g). Compared with A. sinensis decoction pieces and methanol extracts, the agglomerated structure of the DESs extract powder almost disappeared, showing the presence of lamellar structures similar to those of the intestinal wall. Compared with the methanol extract, the DES extract exhibited higher FTIR characteristic peak intensity and peak area integration, as well as stronger scavenging capacities against DPPH and ABTS free radicals. The extraction of organic acids from A. sinensis by DESs is the result of the combined effects of polarity matching, hydrogen bonding, and structural adaptation.

Objective:To investigate the potential characteristic manifestations and application value of the Dynamic Visual Acuity Test(DVAT) in vestibular migraine(VM). Methods:A total of 50 VM patients(case group) and 50 healthy subjects(control group) diagnosed at the Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Shanxi Medical University between November 1, 2023, and December 31, 2024, were enrolled. The case group underwent DVAT, video head impulse test(vHIT), caloric test, and Dizziness Handicap Inventory(DHI) assessment, whereas the control group only received DVAT. Group-based analyses were conducted to examine the effect of age on Dynamic Visual Acuity Loss(DVALoss), as well as the correlations of DVALoss with vestibular function tests and DHI scores. Results:DVALoss in the case group was significantly higher than that in the control group(P<0.001). In both groups, age was significantly and positively correlated with DVALoss(P<0.001). Within the case group, DVALoss was strongly and positively correlated with DHI scores(r=0.807, P<0.001); it was negatively correlated with the vestibulo-ocular reflex(VOR) gain in vHIT, though without clinical significance, and showed no significant association with the caloric test. Age and DVALoss collectively accounted for 71.3% of the variance in DHI scores(R²=0.713), with age exerting a relatively minor actual impact. Conclusion:DVAT can sensitively identify the core functional impairments of VM. DVALoss, as a direct functional reflection of the pathological mechanism of VM, is strongly correlated with DHI scores. Incorporating DVALoss into standardized assessments may provide an objective basis for the diagnosis and management of VM.

Acute respiratory distress syndrome (ARDS) is the leading cause of respiratory failure with high morbidity and mortality. Pulmonary surfactant (PS)-based complementary therapies have exhibited potential for ARDS healing and applied as an adjunctive therapy strategy. Coacervate (Coac) has the characteristics of softness, deformability and excellent molecular enrichment properties, and has attracted extensive attention in the biomedical field. Here PS and coacervate were combined for the potential ARDS treatment. The Coac, fabricated from polyallylamine hydrochloride (PAH) and adenosine triphosphate (ATP) by simple mixing, exhibited soft droplet property and high enrichment for dexamethasone sodium phosphate (DSP). To avoid the fusion effect of membraneless coacervate and endow it with biological functions of PS, liposomes with PS-biomimetic lipid components (PS-lipo) were further introduced to construct PS-biomimetic membranized coacervate (DSP@PS-Coac). The DSP@PS-Coac demonstrated high lung targeting effect and significant penetration efficiency after intravenous injection. Furthermore, PS-lipo replenished the endogenous PS pool and facilitated the distribution of DSP in inflammatory cells in the lung. In the ARDS mouse model, PS-Coac and DSP exerted synergetic anti-inflammatory functions, via reducing the recruitment of inflammatory neutrophils and modulating macrophages into anti-inflammatory phenotype. The overall results confirmed that DSP@PS-Coac may provide a promising delivery option for the treatment of ARDS.
