Abstract
This paper aims to observe the effect of recombinant human brain natriuretic peptide (rhBNP) on treatment of acute carbon monoxide poisoning (ACMP) complicated with heart failure with reduced ejection fraction (HFREF).A total of 103 patients with ACMP complicated with HFREF admitted to our department from October 2016 to March 2020 were observed. Patients were divided into control group (50 cases) and experimental group (53 cases). The control group was given diuretic, vasodilator, and digitalis treatment, and the experimental group was supplemented with rhBNP treatment based on the control group. Patients' general information was collected. The levels of myocardial injury-associated indicators of patients were detected at and after admission.No significant differences were observed in the general data of patients compared with control group. The acute physiology and chronic health enquiry II score of patients was positively correlated with left ventricular ejection fraction (LVEF). At admission, the levels of myocardial injury indicators, N-terminal B-type brain natriuretic peptide, and cardiac ultrasound indexes had no significant difference between the control group and experimental group. However, after admission, the LVEF and stroke output levels were elevated, while the other indicators were all decreased compared with the control group.The rhBNP exerts a protective effect on ACMP-induced cardiomyocyte injury to improve cardiac function, shorten the length of hospital stay, and reduce the incidence and mortality of delayed encephalopathy after carbon monoxide poisoning.

Metabolic syndrome improves cardiovascular dysfunction and survival during cecal ligation and puncture-induced mild sepsis in mice. Life Sci 2021; 286:120033. [PMID: 34627775 DOI: 10.1016/j.lfs.2021.120033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 09/24/2021] [Accepted: 10/03/2021] [Indexed: 12/21/2022]
Abstract
AIMS Sepsis is a potentially fatal systemic inflammatory response and its underlying pathophysiology is still poorly understood. Studies suggest that obesity, a component of metabolic syndrome (MS), is associated with sepsis survival. Therefore, this study focused on investigating the influence of MS on mortality and cardiovascular dysfunction induced by sublethal cecal ligation and puncture (SL-CLP). MAIN METHODS Newborn Swiss mice received monosodium glutamate (MSG) (4 mg kg-1 day-1, s.c.) during the first 5 d of life for MS induction, while the control pups received equimolar saline solution. On the 75th day, SL-CLP was used to induce mild sepsis (M-CLP) in the MS (MS-M-CLP) and control (SAL-M-CLP) mice. The effect of MS on sepsis in mice was assessed by determining the survival rate and quantification of nitric oxide (NO) in the plasma, and associating this data with hematological and cardiovascular parameters. KEY FINDINGS MS improved the survival of septic mice, preventing impairment to hematological and cardiovascular parameters. In addition, MS attenuated plasmatic NO increase, which is a typical feature of sepsis. SIGNIFICANCE These findings provide new insights into the relationship between obesity and mild sepsis in mice, thus revealing an approach in favor of the "obesity paradox."

Abstract
Short chain fatty acids (SCFAs) are known to be actively involved in multiple brain disorders, but their roles in sepsis-associated encephalopathy (SAE) remain unclear. Here, we investigated the neuroprotective effects of SCFAs on SAE in mice. Male C57BL/6 mice were intragastrically pretreated with SCFAs for seven successive days, and then subjected to SAE induced by cecal ligation and puncture. The behavioral impairment, neuronal degeneration, and levels of inflammatory cytokines were assessed. The expressions of tight junction (TJ) proteins, including occludin and zoula occludens-1 (ZO-1), cyclooxygenase-2 (COX-2), cluster of differentiation 11b (CD11b), and phosphorylation of JNK and NF-κB p65 in the brain, were measured by western blot and Immunofluorescence analysis. Our results showed that SCFAs significantly attenuated behavioral impairment and neuronal degeneration, and decreased the levels of IL-1β and IL-6 in the brain of SAE mice. Additionally, SCFAs upregulated the expressions of occludin and ZO-1 and downregulated the expressions of COX-2, CD11b, and phosphorylation of JNK and NF-κB p65 in the brain of SAE mice. These findings suggested that SCFAs could exert neuroprotective effects against SAE in mice.

Abstract
Background To investigate the protective effect of recombinant human brain natriuretic peptide (rhBNP) on myocardial injury after acute carbon monoxide poisoning (ACOP). Methods We retrospectively reviewed medical records of patients with ACOP and high risk of cardiac events admitted to our hospital, and grouped them into rhBNP group and control group according treatments they received. Patients in control group received conventional treatment while those in rhBNP group were treated with rhBNP intravenously for 72 hours on the basis of conventional treatment. Levels of amino-terminal pro-brain natriuretic peptide (NT-proBNP), cardiac troponin I (cTnI), serum creatine kinase MB fraction (CK-MB), aldosterone (ALD), angiotensin II (AT II), and endothelin-1 (ET-1) prior to and after treatment of rhBNP or conventional treatment were collected. Corrected QT dispersion (QTcd) results were calculated based on the electrocardiography data. The left ventricular end diastolic diameter (LVEDD), interventricular septal thickness (IVS), left ventricular ejection fraction (LVEF), and stroke output (SV) were measured using color Doppler echocardiography. Major adverse cardiovascular events (MACEs) that occurred within 1 month after treatment were recorded. Results A total of 135 patients in the rhBNP group and 136 patients in the control group were enrolled. Baseline characteristics between the two groups were similar at admission. Levels of cTnI, CK-MB, and ET-1 in the rhBNP group were significantly lower than those in the control group at day 1, 2 and 3 after treatment (P<0.05). Compared with the control group, levels of QTcd, ALD and AT II in the rhBNP group were significantly lower at day 3 after treatment (P<0.05). After 7 days of treatment, the reduction of NT-proBNP in the rhBNP group was significantly greater than that in the control group at each day (P<0.05), and LVEF, SV and LVEDD in the rhBNP group were all greater than those in the control group. After 1 month of treatment, the incidence of MACEs in the rhBNP group was significantly lower than that in the control group. Conclusions For patients with ACOP and high risk of cardiac events, early treatment of rhBNP can protect injured cardiomyocytes, prevent the injury of carbon monoxide on heart, and reduce the incidence of MACE.

Abstract
OBJECTIVE To identify the association between the changes in the profile of microbial metabolites, inflammatory and autoimmune markers and the dynamics of neurological status in chronic critically ill patients with diseases of the central nervous system (CNS). MATERIAL AND METHODS Sixty serum samples from 37 patients, aged 19-77 years, with severe CNS diseases were studied. The changes in clinical condition were assessed with NIHSS, the Rankin scale, the Glasgow Coma Scale, the FOUR Coma Scale and the Rivermead Mobility Index. The levels of aromatic microbial metabolites (AMM) and several inflammatory and autoimmune biomarkers, including the contents of procalcitonin (PCT) and S100, the activity of leukocyte elastase (LE) and a1-proteinase inhibitor a1-PI, the levels of autoantibodies to S100b and MBP were measured. Serum from 60 age- and sex-matched healthy people with no signs of neurological and somatic pathology was used as a control. RESULTS All patients were divided into groups depending on the neurological dynamics: A - positive (n=16), B - without dynamics (n=15), C - negative (n=6). The study revealed a profile of AMM, as well as inflammatory and autoimmune biomarkers associated with the severity of neurological disorders. A significant increase in acute phase proteins, S-100 level and a decrease in the functional activity of neutrophils (via LE activity) were observed in the serum of patients. The different dynamics of neurological status was associated with the multidirectional changes in the microbial metabolites profile and biomarkers. The correlations between the clinical and biological parameters indicate that AMM might modulate immune reactions in patients with different dynamics of neurological status. CONCLUSION The results suggest the involvement of AMM and the level of immune activation via biomarkers in the pathogenesis of neurological dysfunction. Dynamic changes in the profile of microbial metabolites and the level of activation of the immune system may be a promising tool for prediction of neurological recovery.

Abstract
Sepsis is systemic inflammatory response syndrome with a life-threatening organ dysfunction that is caused by an unbalanced host immune response in an attempt to eliminate invasive microorganisms. We posed questions, "Does sepsis survivor patients have increased risk of neuropsychiatric manifestations?" and "What is the mechanism by which sepsis induces long-term neurological sequelae, particularly substantial cognitive function decline in survivor patients and in pre-clinical sepsis models?" The studies were identified by searching PubMed/MEDLINE (National Library of Medicine), PsycINFO, EMBASE (Ovid), LILACS (Latin American and Caribbean Health Sciences Literature), IBECS (Bibliographical Index in Spanish in Health Sciences), and Web of Science databases for peer-reviewed journals that were published until January 2018. A total of 3555 papers were included in the primary screening. After that, 130 articles were selected for the study. A number of pre-clinical studies have shown an auto amplification of pro-inflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, and IL-6 in the first few hours after sepsis induction, also increased blood-brain barrier permeability, elevated levels of matrix metalloproteinases, increased levels of damage-associated molecular patterns were demonstrated. In addition, the rodents presented long-term cognitive impairment in different behavioral tasks that were prevented by blocking the mechanism of action of these inflammatory mediators. Clinical studies have showed that sepsis survivors presented increased bodily symptoms such as fatigue, pain, visual disturbances, gastrointestinal problems, and neuropsychiatric problems compared to before sepsis. Sepsis leaves the survivors with an aftermath of physiological, neuropsychiatric, and functional impairment. Systematic review registration: CRD42017071755.
