BACKGROUND:Rev-erbα is involved in the regulation of inflammation,but pharmacological activation of Rev-erbα increases the risk for cardiovascular diseases.To reduce the relevant risk,an exploration on SR9009,a Rev-erbα agonist,combined with other drugs to relieve inflammation in skeletal myoblasts was conducted,laying the theoretical foundation for the treatment of inflammation-associated skeletal muscle atrophy. OBJECTIVE:To investigate the relationship of SR9009,indolepropionic acid and nuclear factor-κB signaling pathways in lipopolysaccharide-induced C2C12 myoblasts. METHODS:(1)C2C12 myoblasts were induced to differentiate in the presence of lipopolysaccharide(1 μg/mL).RNA-seq and KEGG pathway analysis were used to study signaling pathways.(2)C2C12 myoblast viability was assessed using the cell counting kit-8 assay to determine optimal concentrations of indolepropionic acid.Subsequently,cells were categorized into control group,lipopolysaccharide(1 μg/mL)group,SR9009(10 μmol/L)+lipopolysaccharide group,indolepropionic acid(80μmol/L)+lipopolysaccharide group,and SR9009+indolepropionic acid+lipopolysaccharide group.ELISA was employed to measure protein expression levels of interleukin-6 in the cultured supernatant.Real-time quantitative PCR were employed to measure mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.Western blot assay were employed to measure protein expression levels of NF-κB p65 and p-NF-κB p65.(3)After Rev-erbα was knocked down by siRNA,knockdown efficiency was assessed by RT-qPCR.And mRNA levels of interleukin-6 and tumor necrosis factor α were also measured. RESULTS AND CONCLUSION:Compared with the blank control group,lipopolysaccharide time-dependently inhibited myofibroblast fusion to form myotubes,the mRNA expression levels of interleukin-6 and tumor necrosis factor α were elevated,and the level of interleukin-6 in the cell supernatant was significantly increased.The results of KEGG pathway showed that the nuclear factor-κB signaling pathway was activated by lipopolysaccharide.Indolepropionic acid exhibited significant suppression of C2C12 myoblasts viability when its concentration exceeded 80 μmol/L.Indolepropionic acid and SR9009 inhibited the activation of NF-κB signaling pathway,thereby played an anti-inflammatory role,and suppressed the mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.Compared with the lipopolysaccharide group,the ratio of p-NF-κB p65/NF-κB p65 protein expression were downregulated.SR9009 combined with indolepropionic acid notably reduced lipopolysaccharide-induced inflammation,further downregulated the mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.The ratio of p-NF-κB p65/NF-κB p65 protein expression was significantly lower than that in the SR9009+lipopolysaccharide group or indolepropionic acid+lipopolysaccharide group.Rev-erbα increases time-dependently with lipopolysaccharide induction.The knockdown efficiency of Rev-erbα by siRNA reached over 58%,and lipopolysaccharide was added after Rev-erbα was successfully knocked down.Compared with the lipopolysaccharide group,the mRNA expression levels of interleukin-6 and tumor necrosis factor α were significantly up-regulated.These results conclude that Rev-erbα may act as a promising pharmacological target to reduce inflammation.SR9009 targeted activation of Rev-erbα combined with indolepropionic acid significantly inhibits the nuclear factor-κB signaling pathway and attenuates the inflammatory response of C2C12 myofibroblasts.Moreover,the combined anti-inflammatory effect is superior to that of the intervention alone.

Objective:To preliminarily explore whether sirtuin1 (SIRT1) activation can inhibit neuronal ferroptosis in rats after traumatic brain injury (TBI) by regulating hypoxia-inducible factor-1α (HIF-1α)-mediated glycolysis.Methods:(1) Six SD rats were randomly divided into sham-operated group and TBI group, with 3 rats in each group; TBI model in the TBI group was established by hydraulic impact method, and rats in the sham-operated group underwent same surgery without impact. Cortical tissues of the two groups were sent for tandem mass tag (TMT) labeled quantitative proteomics detection to analyze the differential expression proteome; Kyoto encyclopedia of genes and genomes (KEGG) and gene set enrichment analysis (GSEA) were used to detect pathway enrichment of the screened differential proteins. (2) Twelve SD rats were randomly divided into sham-operated group and 1-day, 3-day and 7-day post-TBI groups, with 3 rats in each group. Treatment methods were the same as above; Western blotting was used to detect SIRT1 protein expression. (3) Forty-eight rats were randomly divided into sham-operated group, TBI group, TBI+vehicle group and TBI+SIRT1 agonist group, with 12 rats in each group; rats in the sham-operated group and TBI group accepted treatment as above; rats in the TBI+SIRT1 agonist group were intraperitoneally injected with SRT1720 (dissolved in ≤ 5% dimethyl sulfoxide, at a dose of 20 mg/kg) within 30 minutes after modeling, twice a day (with an interval of 12 hours); and rats in the TBI+vehicle group were injected with same dose of dimethyl sulfoxide at the same time. One d after modeling, neurological deficit was assessed using modified Neurological severity score (mNSS), brain water content was measured by dry-wet weight method, histopathological changes in the cortical lesions were observed by HE staining, mitochondrial ultrastructure was examined by transmission electron microscopy, malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in the brain tissues were detected by colorimetry, and protein expressions of SIRT1, HIF-1α (key protein in the glycolytic pathway), glutathione peroxidase 4 (GPX4, key protein in the ferroptosis pathway), and acyl-CoA synthetase long-chain family member 4 (ACSL4, key protein in the ferroptosis pathway) were evaluated by Western blotting.Results:(1) KEGG analysis revealed that the glycolysis pathway and HIF-1 signaling pathway were obviously enriched in the cortical tissues of rats in the TBI group compared with the sham-operated group; GSEA showed that the HIF-1 signaling pathway (mmu04066) and ferroptosis pathway (mmu04216) gene sets in the cortical tissues of rats in the TBI group exhibited enrichment trends compared with those in the sham-operated group. (2) Compared with the sham-operated group, the 1-day, 3-day, and 7-day post-TBI groups had significantly decreased SIRT1 protein expression ( P<0.05), with the most prominent decline in 1-day post-TBI group. (3) Compared with the TBI+vehicle group, rats in the TBI+SIRT1 agonist group showed significantly reduced mNSS score and brain tissue water content (9.83±1.17 vs. 7.66±1.21; [83.62±0.91]% vs. [80.09±0.68]%, P<0.05). HE staining indicated clearer structure of the cortical area at the injury sites, and improved neuron morphology in the TBI+SIRT1 agonist group compared with those in the TBI+vehicle group; and transmission electron microscopy showed reduced mitochondrial shrinkage and partial restoration of cristae structures in the TBI+SIRT1 agonist group compared with those in the TBI+vehicle group. Compared with the TBI+vehicle group, the TBI+SIRT1 agonist group exhibited significantly decreased MDA content ([62.72±9.20] nmol/g vs. [39.34±3.48] nmol/g), increased SOD activity ([1.95±0.23] U/mg vs. [2.48±0.14] U/mg), elevated GPX4 protein expression (0.37±0.04 vs. 0.46±0.03), and decreased HIF-1α and ACSL4 protein expressions (1.16±0.15 vs. 0.81±0.12; 1.14±0.06 vs. 1.29±0.04), with significant differences ( P<0.05). Conclusion:SIRT1 activation can exert neuroprotective effect by inhibiting HIF-1α-mediated glycolysis and reducing neuronal ferroptosis after TBI.

Objective To explore the feasibility and safety of non-anticoagulation veno-venous extracorporeal membrane oxygenation(VV-ECMO)in patients with severe chest trauma.Methods A retrospective cohort study method was used.A total of 19 patients with severe chest trauma who received VV-ECMO with a delayed anticoagulation strategy at Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2018 to October 2021 were included in the delayed anticoagulation group,and 20 patients with severe chest trauma who received VV-ECMO with a non-anticoagulation strategy from November 2021 to October 2024 were included in the non-anticoagulation group.The overall clinical characteristics of the patients were statistically analyzed,including gender,age,injury severity score(ISS),acute physiology and chronic health evaluationⅡ(APACHEⅡ),reason for VV-ECMO,use of vasoactive drugs,oxygenation index(PaO2/FiO2),and interval from injury to VV-ECMO.The primary outcomes were hemorrhagic and thrombotic complications.The secondary outcomes were blood transfusion during VV-ECMO,VV-ECMO time,mechanical ventilation time,intensive care unit(ICU)length of stay,and 28-day mortality.Results There was no significant difference in gender,age,ISS score,APACHEⅡscore,reason for VV-ECMO,use of vasoactive drugs,PaO2/FiO2,and interval from injury to VV-ECMO between the non-anticoagulation group and the delayed anticoagulation group.There was no significant difference in overall incidence of hemorrhagic and thrombotic between the two groups[incidence of hemorrhagic complications:15.0%(3/20)vs.31.6%(6/19),incidence of thrombotic:15.0%(3/20)vs.5.3%(1/19),both P>0.05].The infusion rate of 4 or more paked red blood cell(PRBC)within 24 hours during VV-ECMO in the non-anticoagulation group was significantly lower than that in the delayed anticoagulation group[5.0%(1/20)vs.31.6%(6/19),P<0.05].The amount of PRBC and platelet transfusion and the time on VV-ECMO in the non-anticoagulation group during VV-ECMO were significantly lower than those in the delayed anticoagulation group[PRBC(U):5.8±3.8 vs.8.1±3.1,platelets(U):1(0,1)vs.2(1,3),time on VV-ECMO(hours):71.55±24.37 vs.114.21±34.08,all P<0.05].There were no statistically significant differences in the amount of plasma and cryoprecipitate transfusion during VV-ECMO,mechanical ventilation time,ICU hospitalization time,and 28-day mortality between the two groups.Conclusion For patients with severe chest trauma receiving VV-ECMO withholding routine systemic anticoagulation did not result in thrombotic complications or higher mortality and required less PRBC and platelet transfusions.Non-anticoagulant VV-ECMO is safe and feasible for patients with severe chest trauma with high risk of bleeding.

Objective:To investigate the association between different socioeconomic status (SES) levels and the incidence of sensory impairment (SI) in the Chinese population.Methods:This study adopted a prospective cohort design, utilizing data from the China Health and Retirement Longitudinal Study (CHARLS) collected in July or August 2011. Participants who met the inclusion and exclusion criteria were followed up every 2-3 years until the onset of SI or the end of the follow-up period (August 2018). Based on educational attainment and annual per capita household expenditure, participants were classified into four SES groups: low, lower-middle, upper-middle, and high SES. Logistic regression was employed to analyze the relationship between different SES levels and the incidence of SI.Results:A total of 7 415 participants were included in the study, with a mean follow-up duration of 4.9 years. A total of 3 644 cases of incident SI were recorded (49.1%). Compared with the high SES group, the risk of developing SI was progressively higher in the upper-middle SES group ( OR=1.42, 95% CI: 1.03-1.96), lower-middle SES group ( OR=1.83, 95% CI: 1.29-2.60), and low SES group ( OR=2.04, 95% CI: 1.42-2.94) ( P for trend<0.001). Conclusions:SES is closely associated with new-onset SI. Enhancing SES may help reduce the risk of developing SI.

OBJECTIVE To explore the molecular characteristics of small colony variants(SCVs)of Staphylococcus aureus isolates so as to provide theoretical bases for clinical control of the persistent and recurrent infections in-duced by the SCVs.METHODS The clinical blood specimens that were collected from the First Affiliated Hospital of Traditional Chinese Medicine University of Guangzhou were cultured to acquire 1 strain of SCV S.aureus S2.The colonial morphology,growth rate,catalase,plasma-coagulase,production capability of biofilm and antimi-crobial susceptibility of the strain SCVs were observed,the growth curve and autolysis curve were drawn,the whole genome sequencing was performed for the S2,the phylogenetic evolution of the genome and the single nu-cleotide polymorphism(SNP)were analyzed.RESULTS The S2 was identified as S.aureus,with the catalase and plasma-coagulase tested positive.The strain was resistant to various types of antibiotics,including macrolides like erythromycin and azithromycin,fluroquinolones such as levofloxacin and ciprofloxacin,and penicillin.The forma-tion of pigment was reduced,the formation of hemolytic rings was low;the growth rate of the strain was slower than that of ATCC 25923(quality control strain)and ZC1(the normal control strain),the autolytic activity of the strain was higher than that of the ATCC 25923 and ZC1,and the biofilm production of the strain was remarkably less than that of the ATCC 29213(P＜0.05).The whole genome sequencing demonstrated that the molecular typ-ing of the S2 was ST239-t030 clone,which harbored a variety of drug resistance genes and virulence genes,and the menB gene had missense mutation.CONCLUSION The formation of SCVs may be associated with the inhibited synthesis of menadione caused by the missense mutation of menB gene.

ObjectiveTo explore the molecular mechanism implicated in the treatment of primary myelofibrosis （PMF） using Chinese medicinal herbs （CMH） by bioinformatics and molecular dynamics. MethodsData mining was performed to find the high-frequency CMH in treating PMF between the year of 1985 and 2024 by searching CNKI， Chinese Science and Technology Journal Database （CCD）， and China Academic Journal Database （CSPD）. TCMSP， SwissTargetPrediction and related reports were used to collect the main active ingredients of high-frequency CMH and their targets. The PMF datasets GSE44426 and GSE124281 were downloaded from GEO database， and R software was used for data normalization and differentially expressed genes （DEGs） screening. Key module hub genes were obtained by weighted gene co-expression network analysis （WGCNA） analysis. The common intersection genes of active ingredient targets， DEGs and key module hub genes of CMH were selected， and the target network was generated using Cytoscape 3.9.2 software. The core target network was generated by topological analysis， while key pathways were selected by GO and KEGG pathway enrichment analysis， and protein interaction relationships were obtained from the String database， so as to construct drug-ingredient-target network and protein interaction network （PPI） relationship diagrams. Discovery Studio 2020 software was used to perform molecular docking， and the GROMACS program was used to perform molecular dynamics simulation. ResultsA total of 21 prescriptions were collected involving 121 herbs. There were 9 herbs with a frequency ≥10 times， which were Danshen （Radix et Rhizoma Salviae Miltiorrhizae）， Huangqi （Radix Astragali）， Baizhu （Rhizoma Atractylodis Macrocephalae）， Danggui （Radix Angelicae Sinensis）， Dangshen （Radix Codonopsis）， Gancao （Radix et Rhizoma Glycyrrhizae）， Baishao （Radix Paeoniae Alba）， Fuling （Poria） and Shudihuang （Radix Rehmanniae Praeparata） from high- to low-frequency. A total of 98 active ingredients and 1125 potential targets were obtained from 9 high-frequency CMH. GSE44426 and GSE124281 data sets screened out 24 gene samples， including 14 of the healthy control group and 10 of the PMF group， and identified 319 DEGs between the two groups， including 122 up-regulated genes and 197 down-regulated genes. WGCNA screened out 24 co-expression module genes and found that the five modules closely related to the onset of PMF were MEpink， MEdarkred， MEblack， MEgrey， and MEturquoise， involving 7112 key module hub genes. The GO and KEGG enrichment analyses indicated that lipids and the atherosclerosis pathways were mainly involved in the mechanism of above high-frequency CMH in treating PMF， which included six hub protein targets： HSP90AA1， HSP90AB1， SRC， MAPK1， IL1B and IL10. From the drug-ingredient-target network， seven active ingredients of CMH targeting at these six hub targets were found， including verbascoside， verbascos isoflavone， kaempferol， luteolin， naringenin， quercetin and pachymic acid. The molecular docking and molecular dynamics analyses showed that the key CMH were Shudihuang， Huangqi， Baishao， Danshen， Gancao and Fuling， and among the seven active ingredients， calycosin had the highest binding affinity with HSP90AB1. ConclusionThe main CMH for the treatment of PMF may be Shudihuang， Huangqi， Baishao， Danshen， Gancao and Fuling， and the active ingredients include verbascoside， verbascos isoflavones， kaempferol， luteolin， naringenin， quercetin and pachymic acid. The relevant targets are HSP90AA1， HSP90AB1， SRC， MAPK1， IL-10， and IL-1β， and the most critical pathways are lipid and atherosclerosis pathways.
