PLoS One 2023; 18:e0295862.

Abstract
Cardiopulmonary bypass (CPB) causes systemic inflammation and endothelial glycocalyx damage. Hydrogen has anti-oxidant and anti-inflammatory properties; therefore, we hypothesized that hydrogen would alleviate endothelial glycocalyx damage caused by CPB. Twenty-eight male Sprague-Dawley rats were randomly divided into four groups (n = 7 per group), as follows: sham, control, 2% hydrogen, and 4% hydrogen. The rats were subjected to 90 minutes of partial CPB followed by 120 minutes of observation. In the hydrogen groups, hydrogen was administered via the ventilator and artificial lung during CPB, and via the ventilator for 60 minutes after CPB. After observation, blood collection, lung extraction, and perfusion fixation were performed, and the heart, lung, and brain endothelial glycocalyx thickness was measured by electron microscopy. The serum syndecan-1 concentration, a glycocalyx component, in the 4% hydrogen group (5.7 ± 4.4 pg/mL) was lower than in the control (19.5 ± 6.6 pg/mL) and 2% hydrogen (19.8 ± 5.0 pg/mL) groups (P < 0.001 for each), but it was not significantly different from the sham group (6.2 ± 4.0 pg/mL, P = 0.999). The endothelial glycocalyces of the heart and lung in the 4% hydrogen group were thicker than in the control group. The 4% hydrogen group had lower inflammatory cytokine concentrations (interleukin-1β and tumor necrosis factor-α) in serum and lung tissue, as well as a lower serum malondialdehyde concentration, than the control group. The 2% hydrogen group showed no significant difference in the serum syndecan-1 concentration compared with the control group. However, non-significant decreases in serum and lung tissue inflammatory cytokine concentrations, as well as in serum malondialdehyde concentration, were observed. Administration of 4% hydrogen via artificial and autologous lungs attenuated endothelial glycocalyx damage caused by partial CPB in rats, which might be mediated by the anti-inflammatory and anti-oxidant properties of hydrogen.

Abstract
Heat stroke (HS) is an acute physical illness associated with a higher risk of organ dysfunction. This study is the first to explore exosomal miR-548x-3p derived from human bone marrow mesenchymal stem cells (BMSCs) in the pyroptosis of vascular endothelial cells (VECs) associated with HS. Human BMSCs-derived exosome alleviated the injury of the heart, liver, kidney and ileum tissues, the increase of IL-1β, IL-18 and TNF-α levels, pyroptosis of endothelial cells and the increase of HGMB1, NLRP3, ASC, caspase1 and GSDMD-N protein expression in HS mice and HS-induced human umbilical vein endothelial cells (HUVECs). miR-548x-3p was down-expressed in HS patients, while up-expressed in BMSCs-derived exosome. BMSCs-ExomiR-548x-3p mimics to inhibit pyroptosis, inflammation and HGMB1/NLRP3 activation in HS-induced HUVECs and HS mice, which were blocked by overexpression of HMGB1. In conclusion, human BMSCs-derived exosomes carried miR-548x-3p mimics to inhibit pyroptosis of VECs through HMGB1 in HS mice.

Abstract
As diabetes rates surge globally, there is a corresponding rise in the number of patients suffering from diabetic kidney disease (DKD), a common complication of diabetes. DKD is a significant contributor to chronic kidney disease, often leading to end-stage renal failure. However, the effectiveness of current medical treatments for DKD leaves much to be desired. Molecular hydrogen (H2) is an antioxidant that selectively reduces hydroxyl radicals, a reactive oxygen species with a very potent oxidative capacity. Recent studies have demonstrated that H2 not only possesses antioxidant properties but also exhibits anti-inflammatory effects, regulates cell lethality, and modulates signal transduction. Consequently, it is now being utilized in clinical applications. Many factors contribute to the onset and progression of DKD, with mitochondrial dysfunction, oxidative stress, and inflammation being strongly implicated. Recent preclinical and clinical trials reported that substances with antioxidant properties may slow the progression of DKD. Hence, we undertook a comprehensive review of the literature focusing on animal models and human clinical trials where H2 demonstrated effectiveness against a variety of renal diseases. The collective evidence from this literature review, along with our previous findings, suggests that H2 may have therapeutic benefits for patients with DKD by enhancing mitochondrial function. To substantiate these findings, future large-scale clinical studies are needed.

Abstract
Heat stroke is a life-threatening disease with high mortality and complications. Endothelial glycocalyx (EGCX) is essential for maintaining endothelial cell structure and function as well as preventing the adhesion of inflammatory cells. Potential relationship that underlies the imbalance in inflammation and coagulation remains elusive. Moreover, the role of EGCX in heat stroke-induced organ injury remained unclear. Therefore, the current study aimed to illustrate if EGCX aggravates apoptosis, inflammation, and oxidative damage in human pulmonary microvascular endothelial cells (HPMEC). Heat stress and lipopolysaccharide (LPS) were employed to construct in vitro models to study the changes of glycocalyx structure and function, as well as levels of heparansulfate proteoglycan (HSPG), syndecan-1 (SDC-1), heparansulfate (HS), tumor necrosis factor-α (TNF-α), interleukin (IL)-6, Von Willebrand factor (vWF), endothelin-1 (ET-1), occludin, E-selectin, vascular cell adhesion molecule-1 (VCAM-1), and reactive oxygen species (ROS). Here, we showed that heat stress and LPS devastated EGCX structure, activated EGCX degradation, and triggered oxidative damage and apoptosis in HPMEC. Stimulation of heat stress and LPS decreased expression of HSPG, increased levels of SDC-1 and HS in culture supernatant, promoted the production and release of proinflammation cytokines (TNF-α and IL-6,) and coagulative factors (vWF and ET-1) in HPMEC. Furthermore, Expressions of E-selection, VCAM-1, and ROS were upregulated, while that of occludin was downregulated. These changes could be deteriorated by heparanase, whereas they meliorated by unfractionated heparin. This study indicated that EGCX may contribute to apoptosis and heat stroke-induced coagulopathy, and these effects may have been due to the decrease in the shedding of EGCX.

Abstract
ABSTRACT Objectives: This study investigated the role and potential involvement of pulmonary vascular glycocalyx degradation in acute lung injury in rats with severe heatstroke (HS). Methods: Rats in an established HS model were exposed to a heated environment for 60 min in an incubator (temperature, 40°C ± 2°C; humidity, 65% ± 5%). Following pretreatment with heparanase III (HPSE III) or heparin, pathological lung injury, arterial blood gas, alveolar barrier disruption, and hemodynamic changes were evaluated. The vascular endothelial structures of the lungs were examined using electron microscopy. The concentration of Evans blue dye in the lungs and arterial blood gas were assessed. An enzyme-linked immunosorbent assay was used to quantify the plasma concentration of heparan sulfate proteoglycan. The expression of glypican-1 and syndecan-1 in pulmonary vessels was measured using immunofluorescence. Western blots were used to detect the expression of TNF-α, IL-6, and vascular endothelial biomarkers in the rat lungs. Pulmonary apoptosis was assessed using a TUNEL (terminal dUTP nick end labeling) assay, and the concentrations of malondialdehyde were measured. Results: Glycocalyx shedding aggravated lung injuries. Severe histopathological damage was observed, and indexes of lung function deviated from abnormal ranges. In addition, pulmonary vascular endothelial cells were disrupted. Compared with the HS group, the plasma concentration of heparan sulfate proteoglycan significantly increased in the HPSE group ( P < 0.05). The expression of glypican-1 and syndecan-1 decreased, and the extravasation of Evans blue dye increased ( P < 0.01). Endothelial biomarker expression increased in the lung tissue, whereas occludin expression decreased. Moreover, TNF-α and IL-6 were overexpressed following heat stress. Furthermore, apoptosis of pulmonary tissues and the concentration of malondialdehyde in rat lungs increased in the HS and HPSE groups. Conclusions : Heatstroke induced pulmonary glycocalyx degradation, which increased vascular permeability and aggravated vascular endothelial dysfunction, contributing to apoptosis, inflammation, and oxidation in the pulmonary tissues.

Abstract
BACKGROUND Hydrogen is a potent antioxidant agent that can easily be administered by inhalation. The aim of the study was to evaluate whether hydrogen protects the endothelial glycocalyx layer after successful cardiopulmonary resuscitation (CPR). METHODS Fourteen anesthetized pigs underwent CPR after induced ventricular fibrillation. During CPR and return of spontaneous circulation, 2% hydrogen gas was administered to seven pigs (hydrogen group) and seven constituted a control group. Biochemistry and sublingual microcirculation were assessed at baseline, during CPR, at the 15th, 30th, 60th, 120th minute. RESULTS All seven subjects from the hydrogen group and six subjects in the control group were successfully resuscitated after 6-10 minutes. At baseline, there were no statistically significant differences in examined variables. After the CPR, blood pH, base excess, and lactate showed significantly smaller deterioration in the hydrogen group than in the control group. By contrast, plasma syndecan-1 and the measured variables obtained via sublingual microcirculation did not change after the CPR; and were virtually identical between the two groups. CONCLUSION In pigs, hydrogen gas inhalation during CPR and post-resuscitation care was associated with less pronounced metabolic acidosis compared to controls. However, we could not find evidence of injury to the endothelium or glycocalyx in any studied groups.

Abstract
Hemorrhagic shock causes vascular endothelial glycocalyx (EGCX) damage and systemic inflammation. Dexmedetomidine (DEX) has anti-inflammatory and EGCX-protective effects, but its effect on
hemorrhagic shock has not been investigated. Therefore, we investigated whether DEX reduces inflammation and protects EGCX during hemorrhagic shock. Anesthetized Sprague-Dawley rats were
randomly assigned to five groups (n=7 per group): no shock (SHAM), hemorrhagic shock (HS), hemorrhagic shock with DEX (HS+DEX), hemorrhagic shock with DEX and the α7 nicotinic type
acetylcholine receptor antagonist methyllycaconitine citrate (HS+DEX/MLA), and hemorrhagic shock with MLA (HS+MLA). HS was induced by shedding blood to a mean blood pressure of 25–30 mmHg,
which was maintained for 30 min, after which rats were resuscitated with Ringer’s lactate solution at three times the bleeding volume. The survival rate was assessed up to 3 h after the
start of fluid resuscitation. Serum tumor necrosis factor-alpha (TNF-α) and syndecan-1 concentrations, and wet-to-dry ratio of the heart were measured 90 min after the start of fluid
resuscitation. The survival rate after 3 h was significantly higher in the HS+DEX group than in the HS group. Serum TNF-α and syndecan-1 concentrations, and the wet-to-dry ratio of heart
were elevated by HS, but significantly decreased by DEX. These effects were antagonized by MLA. DEX suppressed the inflammatory response and serum syndecan-1 elevation, and prolonged
survival in rats with HS.
