Abstract
BACKGROUND Background: Acute lung injury (ALI) is one kind of frequently occurred emergency in Intensive Care Unite with a high mortality. The underlying causes are uncontrolled inflammatory reactions and intractable hypoxemia, which are difficult to control and improve. In the past 10 years, gas medical studies have found that both hydrogen molecules and oxygen molecules have protective effects on acute lung injury by improving inflammatory reactions and hypoxia, respectively. Oxygen is an oxidant and hydrogen is an antioxidant. In this study, we investigated the combined effect of above two-gas molecular on lipopolysaccharide (LPS) -induced acute lung injury. METHODS To clarify whether the combination of hydrogen and oxygen could increase or cancel out the protective effect, an ALI mice model induced by intraperitoneal injection of LPS was established, and the degree of lung tissue and mitochondria damage was evaluated based on the pathological sections, inflammatory factors, wet-dry ratio, bronchoalveolar lavage fluid (BALF). Immunohistochemistry, electron microscopy, western blotting and other detection methods also used to evaluate the therapeutic effect on acute lung injury model. RESULTS We observed that the combined protective effect of hydrogen and oxygen was superior to their respective protective effects, and the specific molecular mechanisms of the two therapies might be different. CONCLUSION Hydrogen plays a more important role in the inflammatory and anti-apoptosis mechanisms, while oxygen improves hypoxia of the body, and thus, its molecular mechanism may be closely associated to the hypoxia pathways.

Isolation of Neuroprotective Anthocyanins from Black Chokeberry ( Aronia melanocarpa) against Amyloid-β-Induced Cognitive Impairment. Foods 2020; 10:foods10010063. [PMID: 33383966 PMCID: PMC7823521 DOI: 10.3390/foods10010063] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 12/21/2020] [Accepted: 12/24/2020] [Indexed: 01/28/2023] Open
Abstract
Black chokeberry (Aronia melanocarpa) fruits are rich in anthocyanins, which are vital secondary metabolites that possess antioxidative properties. The aim of this study was to isolate and purify the anthocyanins from black chokeberry by simulated moving bed (SMB) chromatography, and to investigate the neuroprotective effect of SMB purified anthocyanin against Aβ-induced memory damage in rats. The parameters of the SMB process were studied and optimized. Anthocyanin extracts were identified by HPLC and UPLC-QTOF-MS, and antioxidant abilities were evaluated. The Aβ-induced animal model was established by intracerebral ventricle injection in rat brain. Through the SMB purification, anthocyanins were purified to 85%; cyanidin 3-O-galactoside and cyanidin 3-O-arabinoside were identified as the main anthocyanins by UPLC-QTOF-MS. The SMB purified anthocyanins exhibited higher DPPH and ABTS free radical scavenging abilities than the crude anthocyanins extract. Furthermore, rats receiving SMB purified anthocyanins treatment (50 mg/kg) showed improved spatial memory in a Morris water maze test, as well as protection of the cells in the hippocampus against Aβ toxicity. These results demonstrate that anthocyanins could serve as antioxidant and neuroprotective agents, with potential in the treatment of Alzheimer's disease.

Abstract
This study was designed to investigate the neuroprotective effect of hyperoxygenate hydrogen-rich saline (HOHS) against brain injury induced by carbon monoxide (CO) poisoning in rats. A rat model of CO poisoning was established by administering CO via intraperitoneal injection to male Sprague-Dawley rats. Forty-eight adult male rats were randomly divided into the following groups: normal control group (NG), CO poisoning group (CO), HOS treatment group (hyperoxygenated solution, HOS) and HOHS treatment group (HOHS). After CO poisoning, the carboxyhemoglobin (COHb) contents in the blood of rats in all the CO poisoning groups were increased significantly. However, HOS and HOHS significantly decreased COHb contents, furthermore, the HOHS group had lower COHb contents than the HOS group. Arterial oxygen partial pressure (PaO2) and arterial oxygen saturation (SaO2) results showed that HOS and HOHS could improve the oxygenation of the rats with CO poisoning. Compared with the CO group, the HOS group and the HOHS group had persistently neuroprotective effect on CO-induced brain injury, as assessed by modified neurological severity score (mNSS), furthermore, the HOHS group had better neurological functional recovery than the HOS group. The neuronal apoptosis induced by CO was also evaluated. Except the NG group, all the CO-poisoning groups had varying degrees of neuronal apoptosis. There was lesser degree of neuronal apoptosis in both the HOS group and the HOHS group than that in the CO group. Moreover, the HOHS group had more minor degree of neuronal apoptosis than the HOS group. Compared with the CO group, the free radicals production in the HOS group and the HOHS group were significantly inhibited. In addition, there were significantly difference in the free radicals production between the HOS group and the HOHS group. We could conclude that HOHS exerted a stronger neuroprotective effect against CO-induced brain injury than HOS, and the neuroprotective mechanism of HOHS may be related with inhibition of both neuronal apoptosis and free radicals.

[PMID: 30825755 DOI: 10.1016/j.jss.2019.01.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 12/06/2018] [Accepted: 01/17/2019] [Indexed: 11/26/2022]
Abstract
BACKGROUND Hemorrhagic shock could induce acute lung injury (ALI), which is associated with cell hypoxia, lung tissue inflammation, free radical damage, and excessive cell apoptosis. Our previous studies demonstrated that hyperoxygenated solution could alleviate cell hypoxia. Furthermore, hydrogen-rich solution (HS) could relieve lung tissue inflammation, free radical damage and excessive cell apoptosis. Therefore we hypothesize that Hyperoxygenated Hydrogen-rich solution (HOHS) can protect the lung against ALI. MATERIALS AND METHODS SD rats were randomly divided into five groups (n = 6 at each time point in each group) and were exposed to Hemorrhagic shock induced ALI, and then treated with lactated Ringer's solution (LRS), hyperoxygenated solution, HS, and HOHS, respectively. The protective effects of these solutions were assessed using methods as follows: arterial blood samples were collected for blood gas analysis; Bronchoalveolar lavage fluid was collected for cell count and protein quantification; lung tissue samples were collected to measure wet/dry ratio, as well as levels of T-SOD, MDA, TNF-α, and IL-6; Caspase-3 and TUNEL-positive cells, and pathological changes were observed under light microscope; ALI was scored using the Smith scoring method; ultrastructural changes of lung tissues were further observed with transmission electron microscopy. RESULTS The results indicated that PaO2, PaCO2, and T-SOD increased in the three treatment groups (P < 0.05), most significantly in the HOHS group (P < 0.01) compared with the LRS group; and conversely that the levels of lactate, MDA, TNF-α and IL-6, cell count, protein content, caspase-3 and TUNEL-positive cells as well as ALI score decreased in the three treatment groups (P < 0.05), most significantly in the HOHS group (P < 0.01) compared with the LRS group. Morphological observation with optical microscope and electron microscopy showed that compared with the LRS group, cell damage in the three treatment groups improved to a varying extent, especially evident in the HOHS group. CONCLUSIONS These findings demonstrate that HOHS can protect the lung against ALI induced by hemorrhagic shock.

Abstract
INTRODUCTION Hypoxemic respiratory failure is a common problem in critical care. Current management strategies, including mechanical ventilation and extracorporeal membranous oxygenation, can be efficacious but these therapies put patients at risk for toxicities associated with invasive forms of support. Areas covered: In this manuscript, we discuss intravenous oxygen (IVO2), a novel method to improve oxygen delivery that involves intravenous administration of a physiologic solution containing dissolved oxygen at hyperbaric concentrations. After a brief review of the physiology behind supersaturated fluids, we summarize the current evidence surrounding IVO2. Expert commentary: Although not yet at the stage of clinical testing in the United States and Europe, IVO2 has been used safely in Asia. Furthermore, preliminary laboratory data have been encouraging, suggesting that IVO2 may play a role in the management of patients with hypoxemic respiratory failure in years to come. However, significantly more work needs to be done, including definitive evidence that such a therapy is safe, before it can be included in an intensivist's arsenal for hypoxemic respiratory failure.

Abstract
OBJECTIVE To investigate the correlation between serum S100B level and carbon monoxide (CO) poisoning by meta-analysis. METHODS By searching both English and Chinese language-based electronic databases (PubMed, EBSCO, Ovid, Springerlink, Wiley, Web of Science, Wanfang databases, China national knowledge infrastructure (CNKI), VIP database, etc.) thoroughly, we tabulated and analyzed the collected data with the use of Comprehensive Meta-analysis 2.0 (CMA 2.0). RESULTS Totally 108 studies have been searched initially (92 studies in Chinese, 16 studies in English). Nine case-control studies (4 studies in English, 5 in Chinese) were chosen for an updated meta-analysis including 542 patients with CO poising and 236 healthy controls. Results identified that the serum S100B level were obviously higher than that in healthy controls (SMD=1.600, 95% CI=1.055-2.145, P<0.001). A subgroup based on the ethnicities revealed that the serum S100B level in Caucasian and Asian subgroups was clearly higher than serum S100B level in healthy controls (Asians: SMD=2.0624, 95% CI=1.736-3.511, P<0.001; Caucasians: SMD=0.447, 95% CI=0.197-0.697, P<0.001). CONCLUSION Serum S100B level may be correlated with the CO poisoning and could be effective biomarker for early diagnosis and treatment monitoring in CO poisoning.

Abstract
In this study, the therapeutic effect of olfactory ensheathing cells (OEC) transplantation on brain damage was evaluated on acute carbon monoxide (CO) poisoning rat model. Two weeks after primary culture, OECs were microinjected into hippocampus of CO poisoning rats. Survival of OECs in the host was observed and quantified. OECs survived at 2 weeks, but surviving cell number was found sharply decreased at 6 weeks and reduced to less than 10(3) at 8 weeks after transplantation. At 2 weeks after transplantation, motor function test and cerebral edema assay were performed and followed by pathological examination including hematoxylin and eosin and immunohistochemistry staining to observe the neuron injury and synapsin I and growth associated protein-43 (GAP-43) expression. Furthermore, biomarkers of oxidative stress and apoptosis related proteins in the hippocampus were detected. The results showed that CO exposure led to neurological dysfunction and cerebral edema in rats. After OEC transplantation, neurological function was significantly improved and the cerebral edema was alleviated. In addition, the numbers of neurons and Nissl bodies were increased and synapsin I and GAP-43 protein expressions were upregulated in the hippocampus. Compared with CO poisoned rats, superoxide dismutase activity and glutathione content were both increased and methane dicarboxylic aldehyde level was decreased in the hippocampus of OEC transplanted rats. Moreover, OEC transplantation reduced apoptosis induced by CO exposure. The Bcl-2 expression was significantly upregulated and Bax expression was significantly downregulated. The activity of caspase-3 and the cleaved-poly ADP-ribose polymerase expression were decreased. Taken together, our data suggest that OEC attenuates brain damages induced by acute CO poisoning within 2 weeks after transplantation.

Abstract
The world has experienced some very large shifts in the epidemiology of carbon monoxide poisoning, but it remains one of the most important toxicological global causes of morbidity and mortality. The diagnosis can be quickly confirmed with blood gases (pulse oximeters lack both sensitivity and specificity). Several strong predictors for serious neurological sequelae (prolonged loss of consciousness and elevated S100B) and reduced life expectancy (elevated troponin) are now reasonably well established. Despite this clearly defined high-risk group and extensive research into the pathophysiology, there has been little translation into better treatment. Much of the pathophysiological research has focused on hyperbaric oxygen. Yet it is apparent that clinical trials show little evidence for benefit from hyperbaric oxygen, and the most recent even raises the possibility of harm for repeated courses. More logical and promising potential antidotes have been under-researched, although recently both animal and small human studies suggest that erythropoietin may reduce S100B and prevent neurological sequelae. Major breakthroughs are likely to require further research on this and other treatments that may inhibit post-hypoxic inflammatory responses and apoptosis.
