Background/Aims: Metabolic dysfunction-associated steatohepatitis (MASH) is a significant risk factor for gallstone formation, but mechanisms underlying MASH-related gallstone formation remain unclear. Golgi membrane protein 1 (GOLM1) participates in hepatic cholesterol metabolism and is upregulated in MASH. Here, we aimed to explore the role of GOLM1 in MASH-related gallstone formation. Methods: The UK Biobank cohort was used for etiological analysis. GOLM1 knockout (GOLM1-/-) and wild-type (WT) mice were fed with a high-fat diet (HFD). Livers were excised for histology and immunohistochemistry analysis. Gallbladders were collected to calculate incidence of cholesterol gallstones (CGSs). Biles were collected for biliary lipid analysis. HepG2 cells were used to explore underlying mechanisms. Human liver samples were used for clinical validation. Results: MASH patients had a greater risk of cholelithiasis. All HFD-fed mice developed MASH, and the incidence of gallstones was 16.7% and 75.0% in GOLM1-/- and WT mice, respectively. GOLM1-/- decreased biliary cholesterol concentration and output. In vivo and in vitro assays confirmed that GOLM1 facilitated cholesterol efflux through upregulating ATP binding cassette transporter subfamily G member 5 (ABCG5). Mechanistically, GOLM1 translocated into nucleus to promote osteopontin (OPN) transcription, thus stimulating ABCG5-mediated cholesterol efflux. Moreover, GOLM1 was upregulated by interleukin-1β (IL-1β) in a dose-dependent manner. Finally, we confirmed that IL-1β, GOLM1, OPN, and ABCG5 were enhanced in livers of MASH patients with CGSs. Conclusions In MASH livers, upregulation of GOLM1 by IL-1β increases ABCG5-mediated cholesterol efflux in an OPN-dependent manner, promoting CGS formation. GOLM1 has the potential to be a molecular hub interconnecting MASH and CGSs.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.

Objective:Based on a single-center retrospective study,to explore the efficacy of intervertebral fusion through different approaches combined with pedicle screw internal fixation in the treatment of single-segment low-grade lumbar spondylolisthesis.Methods:This study retrospectively analyzed the clinical data of 87 patients with single-segment low-grade lumbar spondylolisthesis who were treated in our hospital from January 2021 to August 2022,the cases were divided into Group A(41 cases)and Group B(46 cases)according to the differences in surgical methods.Group A received treatment with posterior lumbar interbody fusion(PLIF)combined with pedicle screw internal fixation,while Group B received treatment with percutaneous endoscopic posterior lumbar interbody fusion(PE-PLIF)combined with pedicle screw internal fixation.Both groups were followed up for two years.The Visual Analogue Scale(VAS)scores of the waist and legs,perioperative indicators,recovery of lumbar function[Japanese Orthopaedic Association(JOA)score,Oswestry Disability Index(ODI)score],and serum inflammatory mediators levels[interleukin-1α(IL-1α),transforming growth factor β1(TGF-β1),interleukin-6(IL-6)],the rate of lumbar interbody fusion,the rate of lumbar spondylolisthesis and the incidence of postoperative complications of the two groups were compared.Results:The operation time and the number of intraoperative X-ray fluoroscopy sessions in group B were both more than those in group A,while the hospital stay,the intraoperative blood loss and total incision length in Group B were all shorter than those in group A(P＜0.05).The VAS scores of the waist and legs in both groups decreased at 3 d after operation and the last follow-up(P＜0.05),and the VAS scores of the waist and legs in group B were lower than those in group A(P＜0.05).The ODI scores of both groups decreased at 3 d after operation and the last follow-up,and the ODI scores of group B were lower than those in group A;The JOA score increased,and the JOA scores of group B were all higher than those in group A(P＜0.05).Serum IL-1α,TGF-β1 and IL-6 levels in both groups decreased at 3 d and 7 d after operation,and serum IL-1α,TGF-β1 and IL-6 levels in group B were all lower than those in group A(P＜0.05).There was no statistically significant difference in the incidence of complications,the rate of lumbar interbody fusion,and the rate of lumbar spondylolisthesis between the two groups(P＞0.05).Conclusion:Compared with PLIF,PE-PLIF combined with pedicle screw internal fixation in the treatment of single-segment low-grade lumbar.spondylolisthesis,can better relieve the degree of pain of the waist and legs,improve lumbar dysfunction,regulate serum inflammatory mediators levels more effectively,and has higher safety and significant therapeutic efficacy.

Aim To establish and evaluate an alternative meth-od for detecting skin sensitization of cosmetics based on local lymph node assay using bromodeoxyuridine(BrdU)with flow cytometry(FCM).Methods(1)25％hexyl cinnamic alde-hyde(HCA)was chosen as a positive control with an acetone:olive oil(4∶1,V/V,AOO)mixture as a vehicle control for the experiment.The dorsal sides of both ears of mice were treated with test solutions on day 1,day 2,and day 3.Brdu solution was injected inter-peritoneally on day 5.On day 6,the bilateral ears and mandibular lymph nodes were excised,and the number of Brdu positive cells was measured by flow cytometry.The stim-ulation index(SI)was calculated to identify whether it was ≥3,in order to establish the method of LLNA:Brdu-FCM.(2)BrdU-FCM test was conducted using a blind method with the fif-teen reference substances listed in OECD TG429 whose skin sensitization potentials were known.The test substances were dissolved in AOO,N,N-dimethylformamide(DMF)or dimeth-yl sulfoxide(DMSO)at three different concentrations.Tests were performed the same as above.SI and EC2.7 were calculat-ed to evaluate whether the test substance was categorized as a skin sensitizer.The reliability and accuracy of the method were validated by comparing the classification of test substances with that in OECD TG429.Results The SI for 25％HCA was 3.9,showing positive in the skin sensitization test.It demonstrated that the LLNA:Brdu-FCM test method was properly implemen-ted.Nine test substances(2,4-dinitrochlorobenzene,4-pheny-lenediamine,cobalt chloride,2-mercaptobenzothiazole,hexyl-cinnamaldehyde,eugenol,phenyl benzoate,cinnamic alcohol,imidazolidinyl urea)were positive,and six test substances(methyl methacrylate,chlorobenzene,isopropanol,lactic acid,methyl salicylate,salicylic acid)were negative.The method was evaluated with sensitivity of 90％,specificity of 100％,positive prediction rate of 100％,negative prediction rate of 83％,false positive rate of 0％,false negative rate of 17％and accuracy of 93％.The LLNA:BrdU-FCM assay could correctly categorize the test substances that were skin sensitizers or non-sensitizers.Conclusion The LLNA:BrdU-FCM assay appears to be a relia-ble predictor of skin sensitization protential of chemicals,and it is expected to an alternative method for identifying skin sensitization as a supplementary in safety evaluation of cosmetic ingredient.

Objective To investigate the clinicopathological parameters and risk factors of the patients with connective tissue disease-associated interstitial lung disease(CTD-ILD)complicated with Epstein-Barr virus(EBV)viraemia.Methods The CTD-ILD pa-tients admitted to Department of Respiratory and Critical Care Medicine,Nanjing Drum Tower Hospital from January 2023 to April 2024 were collected.Based on the detection results of EBV DNA,the patients were divided into the EBV DNA(+)group and EBV DNA(-)group.The clinicopathological parameters of the two groups were analyzed.Results Out of 162 CTD-ILD patients who underwent EBV DNA testing,a total of 28 were found to have EBV viraemia.The levels of serum albumin([32.7±4.1]g/L vs[34.8±3.8]g/L,t=2.559,P＜0.05),oxygenation index([268.5±94.0]mmHg vs[323.2±120.9]mmHg,t=2.062,P＜0.05),and percentages of predicted diffusing capacity for carbon monoxide([30.9±15.3]% vs[44.9±18.8]%,t=2.127,P＜0.05])in the EBV DNA(+)group were significantly lower than those in the EBV DNA(-)group,while the levels of lactate dehydrogenase(LDH,[369.1±206.2]U/L vs[298.8±128.7]U/L,t=2.335,P＜0.05)were significantly higher than that in the EBV DNA(-)group.The acute exacerbation of ILD in the EBV DNA(+)group was more common than that in the EBV DNA(-)group(P＜0.05).Multivariate Lo-gistic analysis showed that honeycombing and low oxygenation index were independent risk factors of CTD-ILD patients complicated with EBV viraemia.Conclusion The CTD-ILD patients complicated with EBV viraemia have poorer oxygenation and are more prone to suf-fer from acute exacerbation of ILD.Honeycombing in chest HRCT and low oxygenation index are independent risk factors of CTD-ILD patients complicated with EBV viraemia.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.
