Abstract
Sepsis is a systemic inflammatory response syndrome caused by infection, which has no specific drug at present. UMI-77 can significantly improve the survival rate of septic mice; the detailed role of UMI-77 and its underlying mechanisms in sepsis are not clear. Inflammation array glass chip and proteomic analyses were performed to elucidate the latent mechanism of UMI-77 in the treatment of sepsis. The results showed that 7.0 mg/kg UMI-77 improved the 5 day survival rate in septic mice compared to the LPS group (60.964 vs 9.779%) and ameliorated the pathological conditions. Inflammation array glass chip analysis showed that sepsis treatment with UMI-77 may eventually through the suppression of the characteristic inflammatory storm-related cytokines such as KC, RANTES, LIX, IL-6, eotaxin, TARC, IL-1β, and so on. Proteomics analysis showed that 213 differential expression proteins and complement and coagulation cascades were significantly associated with the process for the UMI-77 treatment of sepsis. The top 10 proteins including Apoa2, Tgfb1, Serpinc1, Vtn, Apoa4, Cat, Hp, Serpinf2, Fgb, and Serpine1 were identified and verified, which play important roles in the mechanism of UMI-77 in the treatment of sepsis. Our findings indicate that UMI-77 exerts an antisepsis effect by modulating the complement cascade pathway and inhibiting inflammatory storm factors.

Remimazolam reduces sepsis-associated acute liver injury by activation of peripheral benzodiazepine receptors and p38 inhibition of macrophages. Int Immunopharmacol 2021; 101:108331. [PMID: 34810122 DOI: 10.1016/j.intimp.2021.108331] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 10/25/2021] [Accepted: 10/28/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Remimazolam is a novel ester-type benzodiazepine with ultrafast onset of sedation effect and fast recovery of consciousness. It has potential advantages in the sedation of sepsis-associated acute liver injury (SALI) patients. However, the effect and mechanism of remimazo lam on inflammation in the liver have not yet been elucidated. This study investigated the anti-inflammatory effects and mechanisms of remimazolam on SALI both in vivo and in vitro. METHODS Lipopolysaccharide (LPS) plus galactosamine treated rat model and LPS-challenged RAW264.7 cells model were constructed to simulate SALI. Next, the models were used to explore the efficacy of remimazolam treatment on SALI. Benzodiazepine receptor inhibitor, PK11195, was also employed. Hepatic injury was assessed by quantifying levels of transaminases, examining liver pathology, and calculating the number of inflammatory cells in the liver. Inflammatory response was evaluated by determining levels of pro-inflammatory cytokines and chemokines in blood, as well as p38 phosphorylation (p-p38) in the liver. RESULTS SALIrat models showed significant liver damage as manifested by increased levels of transaminases, proinflammatory cytokines, chemokines, and p-38. Remimazolam treatment reduced the liver injury and pathological changes, suppressed pro-inflammatory reactions, and elevated p-p38. The protective effect of remimazolam on liver injury was significantly blocked by PK11195. In LPS-stimulated RAW264.7 cells, it was found that treatment with remimazolam reduced the inflammatory response in LPS-treated cells in a time-dependent manner and decreased the level of p-p38. These results suggest that PK11195 can block remimazolam-induced inhibition of proinflammatory cytokine release and p-38 phosphorylation. CONCLUSIONS This study shows that remimazolam can attenuate inflammatory response in SALI, which may be associated with activation of peripheral benzodiazepine receptors and inhibition of p38 phosphorylation in macrophages.

Abstract
BACKGROUND The specific mechanism of action of each anesthetic drug on the immune system is still incompletely known. It is important to know how the various anesthetics used in minimally invasive surgery (MIS) act on the inflammatory response because the choice of the anesthetic agent can influence the patient's immune system. AIM Evaluation of the effect of anesthetic drugs used for total intravenous anesthesia (Propofol and Midazolam) on the inflammatory response after minimally invasive gynecological surgery. PATIENTS, MATERIALS AND METHODS The inflammatory response in 20 female patients who underwent minimally invasive gynecological surgery under which intravenous anesthesia was performed. Depending on the combination of anesthetics used, we subdivided the study group into two groups, Group 1 consisting of the patients (n=10) who were given for total intravenous anesthesia, the combination with Midazolam+Fentanyl, and Group 2 (n=10) the patients who received the combination of Propofol+Fentanyl, respectively. Surgical interventional procedures included day surgery: diagnostic and operative hysteroscopy, endometrial ablation, surgical treatment of vulvar disorders. Serological profiling of patients was performed by dosing the serum concentration of nucleotide-binding domain (NOD) and leucine-rich repeat protein 3 (NLRP3) inflammasomes, interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), IL-10 before and two hours after the surgical procedure. RESULTS In our study, we found that in both groups of patients (Midazolam+Fentanyl - Group 1, Propofol+Fentanyl - Group 2), NLRP3 and cytokines concentrations in the serum were higher after MIS than those before MIS. CONCLUSIONS It appears that both Midazolam and Fentanyl and Propofol and Fentanyl have an immunomodulatory action due to the anti-inflammatory effect of both anesthetics. Therefore, anesthesiologists must choose an anesthetic method that uses individualized anesthetic agents, depending on the patient's immune status and disease.

Abstract
Objective Perioperative neurocognitive disorders (PND) are a common complication in the elderly. Histone deacetylases (HDACs) are a class of enzymes that control the acetylation status of intracellular proteins. Thus, we explored whether HDACs trigger the release of high mobility group box 1 (HMGB1) through altering the acetylation status in the hippocampi of aged mice. Materials and Methods The effect of the Class IIa HDAC in PND was explored using an in vivo form of splenectomy. Sixteen-month-old healthy male C57BL/6J mice were randomly divided into five groups: control, anesthesia plus sham surgery, anesthesia plus splenectomy, LMK235 treatment, and PBS treatment. The hippocampi were harvested on either first, third, or seventh postoperative day. Cognitive function was assessed via a Morris water maze (MWM) test. Quantitative RT-PCR, Western blots and ELISAs were carried out to assess the targeted gene expression at transcriptional and translational levels. Results Splenectomy led to a significant deficiency in spatial memory acquisition, marked decreases in mRNA and protein levels of HDAC4 and HDAC5 in the hippocampus, and increases in the levels of total HMGB1 and acetylated HMGB1. In a similar fashion to splenectomy, treatment with the HDAC4/5 inhibitor LMK235 produced impaired spatial memory and an increase in the expression of HMGB1 and its acetylated counterpart in the hippocampus. Conclusion These results suggest that surgery leads to PND through class IIa HDAC downregulation-triggered HMGB1 release in hippocampus of aged mice. HDACs may be a potential therapeutic target for postoperative cognitive dysfunction.

Abstract
Extracellular cold-inducible RNA-binding protein (eCIRP) is a recently discovered damage-associated molecular pattern. Understanding the precise mechanism by which it exacerbates inflammation is essential. Here we identified that eCIRP is a new biologically active endogenous ligand of triggering receptor expressed on myeloid cells-1 (TREM-1), fueling inflammation in sepsis. Surface plasmon resonance revealed a strong binding affinity between eCIRP and TREM-1, and fluorescence resonance energy transfer assay confirmed eCIRP's interaction with TREM-1 in macrophages. Targeting TREM-1 by its siRNA or a decoy peptide, LP17, or by using TREM-1-/- mice dramatically reduced eCIRP-induced inflammation. We developed a potentially novel 7-aa peptide derived from human eCIRP, M3, which blocked the interaction of TREM-1 and eCIRP. M3 suppressed inflammation induced by eCIRP or agonist TREM-1 antibody cross-linking in murine macrophages or human peripheral blood monocytes. M3 also inhibited eCIRP-induced systemic inflammation and tissue injury. Treatment with M3 further protected mice from sepsis, improved acute lung injury, and increased survival. Thus, we have discovered a potentially novel TREM-1 ligand and developed a new peptide, M3, to block eCIRP-TREM-1 interaction and improve outcomes in sepsis.

Abstract
Substances of abuse induce alteration in neurobehavioral symptoms, which can lead to simultaneous exacerbation of liver injury. The biochemical changes of liver are significantly observed in the abused group of people using illicit drugs or drugs that are abused. A huge amount of work has been carried out by scientists for validation experiments using animal models to assess hepatotoxicity in cases of drugs of abuse. The risk of hepatotoxicity from these psychostimulants has been determined by different research groups. Hepatotoxicity of these drugs has been recently highlighted and isolated case reports always have been documented in relation to misuse of the drugs. These drugs induce liver toxicity on acute or chronic dose dependent process, which ultimately lead to liver damage, acute fatty infiltration, cholestatic jaundice, liver granulomas, hepatitis, liver cirrhosis etc. Considering the importance of drug-induced hepatotoxicity as a major cause of liver damage, this review emphasizes on various drugs of abuse and addiction which induce hepatotoxicity along with their mechanism of liver damage in clinical aspect as well as in vitro and in vivo approach. However, the mechanisms of drug-induced hepatotoxicity is dependent on reactive metabolite formation via metabolism, modification of covalent bonding between cellular components with drug and its metabolites, reactive oxygen species generation inside and outside of hepatocytes, activation of signal transduction pathways that alter cell death or survival mechanism, and cellular mitochondrial damage, which leads to alteration in ATP generation have been notified here. Moreover, how the cytokines are modulated by these drugs has been mentioned here.

Abstract
In recent years, several studies have shown that Rhodiola rosea can enhance cellular immunity and humoral immune function in mice, and thus, it has become a research hotspot. However, its underlying mechanism of action has remained elusive. The present study investigated whether Rhodiola rosea was able to downregulate the expression of tumor necrosis factor-α-inducible protein 8-like 2 (TIPE2), thereby inhibiting the expression of apoptotic genes, attenuating T-lymphocyte apoptosis and improving immunity in septic mice. A mouse model of caecal ligation and puncture (CLP)-induced sepsis was established, and animals in the treatment group were pre-treated with an intraperitoneal injection of Rhodiola rosea extract, while animals in the control group and sham-operated group were injected with an equivalent amount of normal saline. TIPE2, B-cell lymphoma 2 (Bcl-2), Fas and Fas ligand (FasL) mRNA and protein levels in thymic T cells were determined using reverse transcription quantitative polymerase chain reaction and western blot analysis, respectively. Furthermore, the thymus T-lymphocyte apoptosis rate, thymus T-lymphocyte count and thymus T-lymphocyte sub-sets were assessed using flow cytometry. Levels of T-helper cell type 1 (Th1) cytokines [Interleukin (IL)-2, IL-12 and interferon (IFN)-γ] and Th2 cytokines (IL-4 and IL-10) were determined using ELISA. The results showed that, compared to that in the CLP group, the expression of TIPE2, Fas and FasL in the treatment group was significantly decreased, while the expression of Bcl-2 was increased (P<0.05). The thymus lymphocyte count in the CLP group was significantly higher compared with that in the treatment group (P<0.05). Furthermore, the apoptotic rate of thymus T-lymphocytes in the treatment group was significantly lower than that in the CLP group (P<0.05). In addition, treatment with Rhodiola rosea rescued decreased in the counts of the CD3+ T and CD4+ T sub-sets of thymus T lymphocytes in the CLP group (P<0.05), while not affecting the increased levels of Th2 cytokines (IL-4 and IL-10) in the CLP group compared with those in the control groups. In addition, the Th1 cytokines (IL-12, IL-2 and IFN-γ) were significantly increased (P<0.05) in the CLP group, and treatment with Rhodiola rosea led to further increases. The thymus index of septic mice treated with Rhodiola rosea as well as their survival rate were improved as compared with those in the CLP group. These findings suggested that Rhodiola rosea has protective effects against sepsis by decreasing apoptosis, increasing Th1 cytokines and enhancing the host’s immunity via the regulation of TIPE2 expression.
