[PMID: 38027628 PMCID: PMC10658207 DOI: 10.1016/j.heliyon.2023.e21217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Revised: 09/15/2023] [Accepted: 10/18/2023] [Indexed: 12/01/2023] Open
Abstract
The specific role of phlorizin (PHL), which has antioxidant, anti-inflammatory, hypoglycemic, antiarrhythmic and antiaging effects, on myocardial fibrosis (MF) and the related pharmacological mechanisms remain unknown. The objective of this study was to determine the protective actions of PHL on isoprenaline (ISO)-induced MF and its molecular mechanisms in mice. PHL was administered at 100 and 200 mg/kg for 15 consecutive days with a subcutaneous injection of ISO (10 mg/kg). MF was induced by ISO and alleviated by treatment with PHL, as shown by reduced fibrin accumulation in the myocardial interstitium and decreased levels of myocardial enzymes, such as creatinine kinase-MB, lactate dehydrogenase, and aspartate transaminase. In addition, PHL significantly decreased the expression of the fibrosis-related factors alpha smooth muscle actin, collagen I, and collagen III induced by ISO. The generation of intracellular reactive oxygen species induced by ISO was attenuated after PHL treatment. The malondialdehyde level was reduced, whereas the levels of superoxide dismutase, catalase, and glutathione were elevated with PHL administration. Moreover, compared to ISO, the level of Bcl-2 was increased and the level of Bax protein was decreased in the PHL groups. PHL relieved elevated TNF-α, IL-1β, and IL-18 levels as well as cardiac mitochondrial damage resulting from ISO. Further studies showed that PHL downregulated the high expression of hexokinase 1 (HK1), NLRP3, ASC, Caspase-1, and GSDMD-N caused by ISO. In conclusion, our findings suggest that PHL protects against ISO-induced MF due to its antioxidant, anti-apoptotic, and anti-inflammatory activities and via inhibition of pyroptosis mediated by the HK1/NLRP3 signaling pathway in vivo.

[PMID: 37364330 DOI: 10.1016/j.intimp.2023.110482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 06/08/2023] [Accepted: 06/08/2023] [Indexed: 06/28/2023]
Abstract
Salbutamol, which consists of an R-isomer and S-isomer, is an effective and widely used β2 adrenoreceptor agonist that may possess anti-inflammatory properties in addition to its bronchodilator activity. Whether the salbutamol R-isomer has advantages over its racemic mixture and effectiveness in treating endotoxemia and endotoxin-induced lung injury has not been well studied. In this study, we investigated the preventive and therapeutic effects of R-salbutamol (R-sal), S-salbutamol (S-sal), and their racemic mixture (Rac-sal) on a mouse model of lipopolysaccharide (LPS)-induced endotoxemia. Dexamethasone (Dex) was used for comparison. The results showed that R-sal markedly improved the 7-day survival rate of endotoxic mice when administered before and after LPS treatment. Dex was toxic and accelerated the death of endotoxic mice when administered before LPS injection. Histological examination of the lungs revealed that the LPS challenge resulted in acute lung damage, including inflammatory cell infiltration, thickened alveolar septa, and congestion. R-sal pre-treatment effectively inhibited these changes, accompanied by markedly reduced lung myeloperoxidase levels, serum cytokine levels, and lactate release, significant restoration of lymphocyte count, and reduction of monocyte count. This may have occurred through inhibition of M1 macrophage inflammatory responses by enhancement of β-arrestin2 expression and suppression of NF-κB activation. Rac-sal exhibited diminished effects compared to that of R-sal, while S-sal showed enhanced release of some inflammatory cytokines. In addition, R-sal pre-treatment showed a better improvement in prognostic pulmonary function on day 4 compared to that by Rac-sal. Collectively, our results indicate the potential benefits of R-sal in regulating inflammatory responses to endotoxemia and endotoxin-induced lung injury.

Abstract
CONTEXT Acute lung injury (ALI) is a complex, severe inflammation disease with high mortality, and there is no specific and effective treatment for ALI. Qingfei Xiaoyan Wan (QFXYW) has been widely used to treat lung-related diseases for centuries. OBJECTIVE This study evaluates the potential effects and elucidates the therapeutic mechanism of QFXYW against LPS induced ALI in mice. MATERIALS AND METHODS BALB/c Mice in each group were first orally administered medicines (0.9% saline solution for the control group, 0.5 mg/kg Dexamethasone, or 1.3, 2.6, 5.2 g/kg QFXYW), after 4 h, the groups were injected LPS (1.0 mg/kg) to induce ALI, then the same medicines were administered repeatedly. The transcriptomics-based system pharmacological analyses were applied to screen the hub genes, RT-PCR, ELISA, and protein array assay was applied to verify the predicted hub genes and key pathways. RESULTS QFXYW significantly decreased the number of leukocytes from (6.34 ± 0.51) × 105/mL to (4.01 ± 0.11) × 105/mL, accompanied by the neutrophil from (1.41 ± 0.19) × 105/mL to (0.77 ± 0.10) × 105/mL in bronchoalveolar lavage fluid (BALF). Based on Degree of node connection (Degree) and BottleNeck (BN), important parameters of network topology, the protein-protein interaction (PPI) network screened hub genes, including IL-6, TNF-α, CCL2, TLR2, CXCL1, and MMP-9. The results of RT-PCR, ELISA, and protein chip assay revealed that QFXYW could effectively inhibit ALI via multiple key targets and the cytokine-cytokine signalling pathway. CONCLUSIONS This study showed that QFXYW decreased the number of leukocytes and neutrophils by attenuating inflammatory response, which provides an important basis for the use of QFXYW in the treatment of ALI.

Abstract
Emerging data are linking coronavirus disease 2019 (COVID‐19) with an increased risk of developing new‐onset diabetes. The gut has been so far out of the frame of the discussion on the pathophysiology of COVID‐19‐induced diabetes, with the pancreas, liver, and adipose tissue being under the spotlight of medical research. Sodium‐glucose co‐transporters (SGLT) 1 represent important regulators of glucose absorption, expressed in the small intestine where they mediate almost all sodium‐dependent glucose uptake. Similar to what happens in diabetes and other viral infections, SGLT1 upregulation could result in increased intestinal glucose absorption and subsequently promote the development of hyperglycaemia in COVID‐19. Considering the above, the question whether dual SGLT (1 and 2) inhibition could contribute to improved outcomes in such cases sounds challenging, deserving further evaluation. Future studies need to clarify whether putative benefits of dual SGLT inhibition in COVID‐19 outweigh potential risks, particularly with respect to drug‐induced euglycaemic diabetic ketoacidosis, gastrointestinal side effects, and compromised host response to pathogens.

Abstract
Novel coronavirus disease (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Its impact on patients with comorbidities is clearly related to fatality cases, and diabetes has been linked to one of the most important causes of severity and mortality in SARS-CoV-2 infected patients. Substantial research progress has been made on COVID-19 therapeutics; however, effective treatments remain unsatisfactory. This unmet clinical need is robustly associated with the complexity of pathophysiological mechanisms described for COVID-19. Several key lung pathophysiological mechanisms promoted by SARS-CoV-2 have driven the response in normoglycemic and hyperglycemic subjects. There is sufficient evidence that glucose metabolism pathways in the lung are closely tied to bacterial proliferation, inflammation, oxidative stress, and pro-thrombotic responses, which lead to severe clinical outcomes. It is also likely that SARS-CoV-2 proliferation is affected by glucose metabolism of type I and type II cells. This review summarizes the current understanding of pathophysiology of SARS-CoV-2 in the lung of diabetic patients and highlights the changes in clinical outcomes of COVID-19 in normoglycemic and hyperglycemic conditions.

Abstract
The aim of this study was to evaluate the effect of acute sepsis in the periodontal ligament, alveolar and furcation bone in absence of periodontitis induction through histological and immunohistochemical analyses. A septic rat model was established by cecal ligation and puncture (CLP). Twelve rats were randomly divided into CLP (n=6) and Sham (n=6) groups. The animals were euthanized at 24 h and hemimandibles were submitted to histomorfometric (bone matrix, collagenous fibers, fibroblasts, osteocytes, inflammatory cells, and blood vessels) and immunohistochemical (BMP-2/4, RANKL and osteocalcin) evaluation in alveolar bone, furcation bone and periodontal ligament. Our results demonstrated that histomorphometric parameters were similar in alveolar bone, furcation bone and periodontal ligament of Sham and CLP rats. Regarding to immunohistochemical analyses, the number of BMP-2/4 and RANKL immunolabeled cells was also similar in both groups. Furthermore, it was detected a reduction in the osteocalcin immunolabeled cells in periodontal ligaments of CLP compared to Sham rats (p=0.0014). In conclusion, the acute sepsis induction resulted in reduced number of osteocalcin labelled cells in periodontal ligament region. Moreover, no significant histological differences were observed in the periodontium of rats under acute sepsis. Considering the role of osteocalcin in bone remodeling, the study contributes to revealing the importance of careful periodontal evaluation in the presence of sepsis.
