Abstract
OBJECTIVE Sepsis can have severe implications on lung function, leading to acute lung injury (ALI), a major contributor to sepsis-related mortality. Anisodamine hydrobromide (Ani HBr), a bioactive constituent derived from the root of Scopolia tangutica Maxim, a plant endemic to China, has demonstrated efficacy in treating septic shock. We aim to explore whether Ani HBr can alleviate sepsis-triggered ALI and elucidate the fundamental mechanisms involved. MATERIALS AND METHOD The protective effects of Ani HBr were assessed in two models: in vitro, lipopolysaccharide (LPS)-stimulated RAW264.7 cells, and in vivo, cecal ligation puncture (CLP)-induced sepsis. To measure the cell viability of RAW264.7 cells after Ani HBr treatment, we used the CCK-8 assay. We quantified the levels of pro-inflammatory cytokines expression using ELISA. We also measured the expression of pyrotosis indicators by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR), Western blotting, and immunofluorescence. RESULTS Our study demonstrates that Ani HBr can alleviate pulmonary edema, bleeding, and excessive inflammation induced by CLP. Additionally, it exhibits protective effects against cytotoxicity induced by LPS in RAW264.7 macrophage cells. Furthermore, Ani HBr downregulates the mRNA and protein levels of NLRP3, Caspase-1, GSDMD, IL-18, and IL-1β in both animal models and cell cultures, thereby inhibiting pyroptosis in a similar mechanism to AC-YVAD-CMK (AYC)'s blockade of Caspase-1. Moreover, Ani HBr suppresses the production and release of proinflammatory cytokines. CONCLUSION These findings suggest that Ani HBr could serve as a protective agent against sepsis-induced ALI by suppressing pyroptosis.

Abstract
Skeletal muscle trauma such as fracture or crush injury can result in a life-threatening condition called acute compartment syndrome (ACS), which involves elevated compartmental pressure within a closed osteo-fascial compartment, leading to collapse of the microvasculature and resulting in necrosis of the tissue due to ischemia. Diagnosis of ACS is complex and controversial due to the lack of standardized objective methods, which results in high rates of misdiagnosis/late diagnosis, leading to permanent neuro-muscular damage. ACS pathophysiology is poorly understood at a cellular level due to the lack of physiologically relevant models. In this context, microfluidics organ-on-chip systems (OOCs) provide an exciting opportunity to investigate the cellular mechanisms of microvascular dysfunction that leads to ACS. In this article, the state-of-the-art OOCs designs and strategies used to investigate microvasculature dysfunction mechanisms is reviewed. The differential effects of hemodynamic shear stress on endothelial cell characteristics such as morphology, permeability, and inflammation, all of which are altered during microvascular dysfunction is highlighted. The article then critically reviews the importance of microfluidics to investigate closely related microvascular pathologies that cause ACS. The article concludes by discussing potential biomarkers of ACS with a special emphasis on glycocalyx and providing a future perspective.

Abstract
The mechanical environment of vascular endothelial cells (ECs) encompasses a wide range of curvatures due to variations in blood vessel diameters. Integrins, key mediators of cell-matrix interactions, establish connections between the extracellular matrix and the actin cytoskeleton, influencing diverse cellular behaviors. In this study, we explored the impact of spatial confinement on human umbilical vein ECs (HUVECs) cultured within three-dimensional hydrogel microgrooves of varying curvatures and the underlying role of integrins in mediating cellular responses. Employing maskless lithography, we successfully fabricated precise and wall curvatures-controlled hydrogel microgrooves, conferring spatial constraints on the cells. Our investigations revealed substantial alterations in HUVEC behavior within the hydrogel microgrooves with varying sidewall curvatures, marked by reduced cell size, enhanced orientation, and increased apoptosis. Interestingly, microgroove curvature emerged as a crucial factor influencing cell orientation and apoptosis, with rectangular microgrooves eliciting distinct changes in cell orientation, while ring-form microgrooves exhibited higher apoptosis rates. The side-wall effect in the 20 μm region near the microgroove wall had the greatest influence on cell orientation and apoptosis. HUVECs within the microgrooves exhibited elevated integrin expression, and inhibition of αV-integrin by cilengitide significantly curtailed cell apoptosis without affecting proliferation. Additionally, integrin-mediated cell traction force closely correlated with the spatial confinement effect. Cilengitide not only reduced integrin and focal adhesion expression but also attenuated cell traction force and cytoskeletal actin filament alignment. Overall, our findings elucidate the spatial confinement of ECs in hydrogel microgrooves and underscores the pivotal role of integrins, particularly αV-integrin, in mediating cell traction force and apoptosis within this microenvironment.

[PMID: 37823419 PMCID: PMC10754481 DOI: 10.1097/mbc.0000000000001257] [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: 08/08/2023] [Accepted: 09/14/2023] [Indexed: 10/13/2023]
Abstract
Disseminated intravascular coagulation (DIC) is a complex disorder characterized by widespread activation of blood clotting mechanisms throughout the body. Understanding the role of vascular endothelial glycocalyx in the pathogenesis and treatment of DIC is crucial for advancing our knowledge in this field. The vascular endothelial glycocalyx is a gel-like layer that coats the inner surface of blood vessels. It plays a significant role in maintaining vascular integrity, regulating fluid balance, and preventing excessive clotting. In the pathogenesis of DIC, the disruption of the vascular endothelial glycocalyx is a key factor. Pathological conditions trigger the activation of enzymes, including heparanase, hyaluronase, and matrix metalloproteinase. This activation leads to glycocalyx degradation, subsequently exposing endothelial cells to procoagulant stimuli. Additionally, the ANGPTs/Tie-2 signaling pathway plays a role in the imbalance between the synthesis and degradation of VEG, exacerbating endothelial dysfunction and DIC. Understanding the mechanisms behind glycocalyx degradation and its impact on DIC can provide valuable insights for the development of targeted therapies. Preservation of the glycocalyx integrity may help prevent the initiation and propagation of DIC. Strategies such as administration of exogenous glycocalyx components, anticoagulant agents, or Tie-2 antibody agents have shown promising results in experimental models. In conclusion, the vascular endothelial glycocalyx plays a crucial role in the pathogenesis and treatment of DIC. Further research in this field is warranted to unravel the complex interactions between the glycocalyx and DIC, ultimately leading to the development of novel therapies.

Abstract
BACKGROUND Septic shock is the development of sepsis to refractory circulatory collapse and metabolic derangements, characterized by persistent hypotension and increased lactate levels. Anisodamine hydrobromide (Ani HBr) is a Chinese medicine used to improve blood flow in circulatory disorders. The purpose of this study was to determine the therapeutic efficacy of Ani HBr in the treatment of patients with septic shock. METHODS This was a prospective, multicenter, randomized controlled trial focusing on patients with septic shock in 16 hospitals in China. Patients were randomly assigned in a 1:1 ratio to either the treatment group or the control group. The primary endpoint was 28-day mortality. The secondary outcomes included 7-day mortality, hospital mortality, hospital length of stay, vasopressor-free days within 7 days, etc. These indicators were measured and collected at 0, 6h, 24h, 48h, 72h and 7d after the diagnosis. RESULTS Between September 2017 and March 2021, 404 subjects were enrolled. 203 subjects received Ani HBr and 201 subjects were assigned to the control group. The treated group showed lower 28-day mortality than the control group. Stratified analysis further showed significant differences in 28-day mortality between the two groups for patients with a high level of illness severity. We also observed significant differences in 7-day mortality, hospital mortality and some other clinical indicators between the two groups. CONCLUSION Ani HBr might be an important adjuvant to conventional treatment to reduce 28-day mortality in patients with septic shock. A large-scale prospective randomized multicenter trial is warranted to confirm our results.

Abstract
Sepsis is a serious disease with high mortality and has been a hot research topic in medical research in recent years. With the continuous reporting of in-depth research on the pathological mechanisms of sepsis, various compounds have been developed to prevent and treat sepsis. Natural small-molecule compounds play vital roles in the prevention and treatment of sepsis; for example, compounds such as resveratrol, emodin, salidroside, ginsenoside, and others can modulate signaling through the NF-κB, STAT3, STAT1, PI3K, and other pathways to relieve the inflammatory response, immunosuppression, and organ failure caused by sepsis. Here, we discuss the functions and mechanisms of natural small-molecule compounds in preventing and treating sepsis. This review will lay the theoretical foundation for discovering new natural small-molecule compounds that can potentially prevent and treat sepsis.

Abstract
PURPOSE Sepsis has complex pathophysiological mechanisms that bring new challenges in the treatment of sepsis at a time when the intestinal microcirculation in sepsis is receiving increasing attention. Dl-3-n-butylphthalide (NBP), which is a drug that can improve multiorgan ischemic diseases, is also worth examining to improve the intestinal microcirculation in sepsis. METHODS In this study, male Sprague-Dawley rats were divided into the sham group (n = 6), CLP group (n = 6), NBP group (n = 6) and NBP + LY294002 group (n = 6). The rat model of severe sepsis was established by cecal ligation and puncture (CLP). Abdominal wall incisions and sutures were performed in the first group, and CLP was performed in the latter three groups. Normal saline/NBP/NBP + LY294002 solution was injected intraperitoneally 2 h or 1 h before modeling. Hemodynamic data (blood pressure and heart rate) were recorded at 0, 2, 4 and 6 h. Sidestream dark field (SDF) imaging and the Medsoft System were used to observe the intestinal microcirculation of rats and obtain data at 0, 2, 4, and 6 h. Six hours after the model was established, the serum levels of TNF-α and IL-6 were measured to evaluate the level of systemic inflammation. Pathological damage to the small intestine was evaluated by electron microscopy and histological analysis. The expression levels of P-PI3K, PI3K, P-AKT, AKT, LC3 and p62 in the small intestine were analyzed by Western blotting. The expressions of P-PI3K, P-AKT, LC3 and P62 in small intestine were detected by immunohistochemical staining. RESULTS NBP improved intestinal microcirculation disturbances in septic rats, alleviated the systemic inflammatory response, reduced the destruction of the small intestinal mucosa and the disruption of microvascular endothelial cells, and alleviated autophagy in vascular endothelial cells. NBP increased the ratio of P-PI3K/total PI3K, P-AKT/total AKT, and P62/β-actin and decreased the ratio of LC3 II/LC3 I. CONCLUSION NBP ameliorated intestinal microcirculation disturbances and the destruction of small intestinal vascular endothelial cells in septic rats by activating the PI3K/Akt signaling pathway and regulating autophagy.

Abstract
Anisodamine is an anticholinergic drug extracted and isolated from the Anisodus tanguticus (Maxim.) Pascher of the Solanaceae family which is also a muscarinic receptor antagonist. Owing to the lack of natural sources of anisodamine, synthetic products are now used. Using ornithine and arginine as precursor compounds, putrescine is catalyzed by different enzymes and then undergoes a series of reactions to produce anisodamine. It has been used clinically to protect cardiac function and treat septic shock, acute pancreatitis, calculous renal colic, bronchial asthma, blood circulation disturbances, jaundice, analgesia, vertigo, acute poisoning, and other conditions.This review describes the relevant pharmacokinetic parameters. Anisodamine is poorly absorbed in the gastrointestinal tract, and it is not as effective as intravenous administration. For clinical medication, intravenous infusion should be used rather than rapid intravenous injection. With the advancement of research in recent years, the application scope of anisodamine has expanded, with significant developments and application values surging.This review systematically describes the sources, pharmacokinetics, pharmacological effects and clinical application of anisodamine, in order to provide a basis for clinical use.

Abstract
Sepsis is a systemic inflammatory response syndrome caused by infection, following with acute injury to multiple organs. Sepsis-induced acute kidney injury (AKI) is currently recognized as one of the most severe complications related to sepsis. The pathophysiology of sepsis-AKI involves multiple cell types, including macrophages, vascular endothelial cells (ECs) and renal tubular epithelial cells (TECs), etc. More significantly, programmed cell death including apoptosis, necroptosis and pyroptosis could be triggered by sepsis in these types of cells, which enhances AKI progress. Moreover, the cross-talk and connections between these cells and cell death are critical for better understanding the pathophysiological basis of sepsis-AKI. Mitochondria dysfunction and oxidative stress are traditionally considered as the leading triggers of programmed cell death. Recent findings also highlight that autophagy, mitochondria quality control and epigenetic modification, which interact with programmed cell death, participate in the damage process in sepsis-AKI. The insightful understanding of the programmed cell death in sepsis-AKI could facilitate the development of effective treatment, as well as preventive methods.

Abstract
Cell death of endothelial cells (ECs) is a common devastating consequence of various vascular-related diseases. Atherosclerosis, hypertension, sepsis, diabetes, cerebral ischemia and cardiac ischemia/reperfusion injury, and chronic kidney disease remain major causes of morbidity and mortality worldwide, in which ECs are constantly subjected to a great amount of dynamic changed mechanical forces including shear stress, extracellular matrix stiffness, mechanical stretch and microgravity. A thorough understanding of the regulatory mechanisms by which the mechanical forces controlled the cell deaths including apoptosis, autophagy, and pyroptosis is crucial for the development of new therapeutic strategies. In the present review, experimental and clinical data highlight that nutrient depletion, oxidative stress, tumor necrosis factor-α, high glucose, lipopolysaccharide, and homocysteine possess cytotoxic effects in many tissues and induce apoptosis of ECs, and that sphingosine-1-phosphate protects ECs. Nevertheless, EC apoptosis in the context of those artificial microenvironments could be enhanced, reduced or even reversed along with the alteration of patterns of shear stress. An appropriate level of autophagy diminishes EC apoptosis to some extent, in addition to supporting cell survival upon microenvironment challenges. The intervention of pyroptosis showed a profound effect on atherosclerosis. Further cell and animal studies are required to ascertain whether the alterations in the levels of cell deaths and their associated regulatory mechanisms happen at local lesion sites with considerable mechanical force changes, for preventing senescence and cell deaths in the vascular-related diseases.

Drost CC, Rovas A, Kümpers P. Protection and rebuilding of the endothelial glycocalyx in sepsis - Science or fiction? Matrix Biol Plus 2021; 12:100091. [PMID: 34877522 PMCID: PMC8633034 DOI: 10.1016/j.mbplus.2021.100091] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 10/14/2021] [Accepted: 10/26/2021] [Indexed: 12/17/2022] Open
Abstract
The endothelial glycocalyx (eGC), a delicate carbohydrate-rich structure lining the luminal surface of the vascular endothelium, is vital for maintenance of microvascular homeostasis. In sepsis, damage of the eGC triggers the development of vascular hyperpermeability with consecutive edema formation and organ failure. While there is evidence that protection or rebuilding of the eGC might counteract sepsis-induced vascular leakage and improve outcome, approved therapeutics are not yet available. This narrative review aims to outline possible therapeutic strategies to ameliorate organ dysfunction caused by eGC impairment.
