Abstract
Exposure to fine particulate matter with a diameter ≤2.5 μm (PM2.5) can result in serious inflammation and oxidative stress in lung tissue. However, there is presently very few effective treatments for PM2.5-induced many pulmonary diseases, such as acute lung injury (ALI). Herein, curcumin-loaded reactive oxygen species (ROS)-responsive hollow mesoporous silica nanoparticles (Cur@HMSN-BSA) are proposed for scavenging the intracellular ROS and suppressing inflammatory responses against PM2.5-induced ALI. The prepared nanoparticles were coated with bovine serum albumin (BSA) via an ROS-sensitive thioketal (TK)-containing linker, in which the TK-containing linker would be cleaved by the excessive amounts of ROS in inflammatory sites to induce the detachment of BSA from the nanoparticles surface and thus triggering release of loaded curcumin. The Cur@HMSN-BSA nanoparticles could be used as ROS scavengers because of their excellent ROS-responsiveness, which were able to efficiently consume high concentrations of intracellular ROS. Furthermore, it was also found that Cur@HMSN-BSA downregulated the secretion of several important pro-inflammatory cytokines and promoted the polarization from M1 phenotypic macrophages to M2 phenotypic macrophages for eliminating PM2.5-induced inflammatory activation. Therefore, this work provided a promising strategy to synergistically scavenge intracellular ROS and suppress the inflammation responses, which may serve as an ideal therapeutic platform for pneumonia treatment.

Front Med (Lausanne) 2021; 8:685032. [PMID: 34222291 PMCID: PMC8247919 DOI: 10.3389/fmed.2021.685032] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 05/26/2021] [Indexed: 12/18/2022] Open
Abstract
Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly, and oxidative damage to retinal pigment epithelial (RPE) cells plays a major role in the pathogenesis of AMD. Exposure to high levels of atmospheric particulate matter (PM) with an aerodynamic diameter of <2.5 μm (PM2.5) causes respiratory injury, primarily due to oxidative stress. Recently, a large community-based cohort study in the UK reported a positive correlation between PM2.5 exposure and AMD. Sulforaphane (SFN), a natural isothiocyanate found in cruciferous vegetables, has known antioxidant effects. However, the protective effects of SNF in the eye, especially in the context of AMD, have not been evaluated. In the present study, we evaluated the effect of SFN against PM2.5-induced toxicity in human RPE cells (ARPE-19) and elucidated the molecular mechanism of action. Exposure to PM2.5 decreased cell viability in ARPE-19 cells in a time- and dose-dependent manner, potentially due to elevated intracellular reactive oxygen species (ROS). SFN treatment increased ARPE-19 cell viability and decreased PM2.5-induced oxidative stress in a dose-dependent manner. PM2.5-induced downregulation of serum- and glucocorticoid-inducible kinase 1 (SGK1), a cell survival factor, was recovered by SFN. PM2.5 treatment decreased the enzymatic activities of the antioxidant enzymes including superoxide dismutase and catalase, which were restored by SFN treatment. Taken together, these findings suggest that SFN effectively alleviates PM2.5-induced oxidative damage in human ARPE-19 cells via its antioxidant effects, and that SFN can potentially be used as a therapeutic agent for AMD, particularly in cases related to PM2.5 exposure.

Am J Transl Res 2021; 13:5027-5034.

Abstract
UNLABELLED To estimate the efficacy of ulinastatin (UTI) plus biapenem (BIPM) in the treatment of severe pneumonia in the elderly and its influence on pulmonary function (PF) and inflammatory cytokines. METHODS We included 97 elderly patients with severe pneumonia in the present study. Patients in control group (n=47) were given BIPM, and those in research group (n=50) were treated with BIPM plus UTI. The clinical efficacy, adverse reactions, arterial blood gas (ABG) indices, PF and inflammatory cytokines were recorded. RESULTS Patients in the research group had earlier fever clearance, inflammation absorption and cough disappearance than those in control group, as well as better clinical efficacy. In addition, no significant differences were found in the incidence of adverse reactions between the two groups during treatment. Monitoring changes in ABG indices, PF, and inflammatory cytokines revealed increased levels of PaO2, pH, FEV1, FVC, FEV1/FVC after treatment, but levels of PaCO2, IL-1β, IL-6, TNF-α, and hs-CRP decreased compared to before treatment. Levels of indices that increased after treatment in the research group were higher than those in the control group, whereas the levels of other indices that decreased after treatment were lower. CONCLUSION The combination of UTI and BIPM shortens the time of symptom disappearance, enhances PF, and inhibits inflammation, achieving higher efficacy in the treatment of severe pneumonia in the elderly.
