Objective To examine the changing antimicrobial resistance profile of Enterobacter spp.isolates in 53 hospitals across China from 2015 t0 2021.Methods The clinical isolates of Enterobacter spp.were collected from 53 hospitals across China during 2015-2021 and tested for antimicrobial susceptibility using Kirby-Bauer method or automated testing systems according to the CHINET unified protocol.The results were interpreted according to the breakpoints issued by the Clinical & Laboratory Standards Institute(CLSI)in 2021(M100 31st edition)and analyzed with WHONET 5.6 software.Results A total of 37 966 Enterobacter strains were isolated from 2015 to 2021.The proportion of Enterobacter isolates among all clinical isolates showed a fluctuating trend over the 7-year period,overall 2.5％in all clinical isolates amd 5.7％in Enterobacterale strains.The most frequently isolated Enterobacter species was Enterobacter cloacae,accounting for 93.7％(35 571/37 966).The strains were mainly isolated from respiratory specimens(44.4±4.6)％,followed by secretions/pus(16.4±2.3)％and urine(16.0±0.9)％.The strains from respiratory samples decreased slightly,while those from sterile body fluids increased over the 7-year period.The Enterobacter strains were mainly isolated from inpatients(92.9％),and only(7.1±0.8)％of the strains were isolated from outpatients and emergency patients.The patients in surgical wards contributed the highest number of isolates(24.4±2.9)％compared to the inpatients in any other departement.Overall,≤ 7.9％of the E.cloacae strains were resistant to amikacin,tigecycline,polymyxin B,imipenem or meropenem,while ≤5.6％of the Enterobacter asburiae strains were resistant to these antimicrobial agents.E.asburiae showed higher resistance rate to polymyxin B than E.cloacae(19.7％vs 3.9％).Overall,≤8.1％of the Enterobacter gergoviae strains were resistant to tigecycline,amikacin,meropenem,or imipenem,while 10.5％of these strains were resistant to polycolistin B.The overall prevalence of carbapenem-resistant Enterobacter was 10.0％over the 7-year period,but showing an upward trend.The resistance profiles of Enterobacter isolates varied with the department from which they were isolated and whether the patient is an adult or a child.The prevalence of carbapenem-resistant E.cloacae was the highest in the E.cloacae isolates from ICU patients.Conclusions The results of the CHINET Antimicrobial Resistance Surveillance Program indicate that the proportion of Enterobacter strains in all clinical isolates fluctuates slightly over the 7-year period from 2015 to 2021.The Enterobacter strains showed increasing resistance to multiple antimicrobial drugs,especially carbapenems over the 7-year period.

Objective:To explore the relationship between the longitudinal change trajectory of white blood cell (WBC) and new-onset type 2 diabetes mellitus(T2DM).Methods:It was a prospective cohort study. A total of 2 792 people who underwent health examinations at the Health Management Center of the Affiliated Hospital of Qingdao University from January 2019 to December 2023 for five consecutive years and met the research standards were selected as the study subjects. Group-based trajectory modeling (GBTM) was established. The target population was divided into three groups based on the longitudinal change trajectory of WBC: low-stable group, medium-stable group and high-stable group. The cumulative incidence of T2DM in the three groups were analyzed. Multivariate Cox proportional risk regression models were used to analyze the correlation between different WBC trajectory groups and the risk of T2DM in total population, males and females. A restricted cubic spline regression (RCS) model was used to analyze the dose-response relationship between baseline WBC and risk of T2DM.Results:The cumulative incidence rate of T2DM in low-stable group, medium-stable group and high-stable group increased gradually, which was 2.5%, 5.3% and 6.9%, respectively ( χ2=19.024, P<0.001). After adjusting for multiple confounding factors in the Cox proportional hazards regression model, no significant difference in the incidence risk of T2DM among the three WBC trajectory groups in males; While the hazard ratios in the high-stable and medium-stable group in women was 2.852(95% CI: 1.067-7.628) and 2.588 (95% CI: 1.133-5.912), respectively, when compared with that in the low-stable group (both P<0.05). RCS curve analysis showed a linear relationship between WBC and the risk of T2DM in female ( Pnon-linear=0.956), when the WBC count was>5.53×10 9/L, the risk of T2DM increased with the rise of WBC. Conclusion:Higher WBC trajectory is positively correlated with the risk of new-onset T2DM in female health examination population.

Objective:To investigate the 10-years risk for cardiovascular diseases(CVD) among different subtypes of pre-diabetes(Pre-DM) residents aged 40 and above in Guiyang urban area and to analyze the influencing factors.Methods:A total of 5 798 residents who participated in the " Risk Evaluation of cAncers in Chinese diabe Tic Individuals: a lONgitudinal(REACTION) Study" were selected to undergo oral glucose tolerance test and glycated hemoglobin test. According to the Pre-DM diagnostic criteria, normal glucose tolerance(NGT), impaired fasting glucose(IFG), impaired glucose tolerance(IGT), and diabetes mellitus were defined based on glycated hemoglobin(IA1C), and were combined into four groups: NGT group, single subtype group(IFG, IGT, IA1C), two-subtype combination group(IFG+ IGT, IFG+ IA1C, IGT+ IA1C), and three-subtype combination group(IFG+ IGT+ IA1C). Ten-year cardiovascular disease occurrence was investigated. The logistic regression model was used to analyze the risk of CVD occurrence in different subtypes of Pre-DM residents. Results:(1)The incidence in the single subtype group, two subtypes group and three subtypes group of CVD was 6.6%(182/2 752), 8.4%(135/1 613) and 9.6%(53/551) , respectively, all higher than NGT group at 5.2%(46/882). (2) Regardless of diagnosed by fasting blood glucose, 2 h blood glucose, or glycated hemoglobin, the 10-year CVD incidence rates(8.7%, 8.6%, 7.6%) in Pre-DM were higher than that in the NGT group(5.2%; all P<0.05). (3)After multivariate adjustment, compared with the NGT group, the 10-year CVD risk gradually increased in the single subtype group, two-subtype group, and three-subtype group, with OR of 1.03(95% CI 0.74-1.45), 1.08(95% CI 0.75-1.54), and 1.16(95% CI 0.75-1.78), respectively. Conclusion:The Pre-DM population has a higher 10-year risk for CVD, and the risk increases gradually with the accumulation of subtypes. Therefore the prevention and treatment of CVD should focus on the management of the Pre-DM population.

Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.

Objective To assess the effectiveness and safety of combining methylprednisolone with myco-phenolate mofetil in managing moderate to severe active Graves'ophthalmopathy(GO),and to compare its efficacy against methylprednisolone monotherapy.Methods A retrospective study was conducted to select patients with moderate to severe active GO who received treatment at the Department of Endocrinology and Metabolism,Guizhou Medical University Affiliated Hospital,from January 2019 to January 2024.The patients were divided into two groups:a combination group receiving methylprednisolone combined with mycophenolate mofetil,and a mono-therapy group receiving methylprednisolone alone.The objective was to compare changes in visual score,appearance score,clinical activity score(CAS),eye protrusion,eye fissure width,and eye movement between the two groups of patients while documenting any adverse events.Results A total of 98 patients were enrolled in the study,comprising 32 patients in the combination group and 61 patients in the monotherapy group.Both groups exhibited improvements in quality of life scores,CAS,and degree of protrusion following treatment compared to baseline.However,at the end of the 12-week treatment period,there was no statistically significant difference(P>0.05)observed between the two groups regarding changes in visual scores,appearance scores,CAS,protrusion degree,fissure width,and proportion of reduced eye movement before and after treatment.Notably though,the combined therapy group demon-strated a significantly higher improvement rate for pain relief and reduction of eyelid congestion during eye movement when compared to the monotherapy group(P<0.001).At the endpoint of treatment,there were no statistically significant differences in appearance score,protrusion degree,tear width,and reduction in eye movement between the two groups before and after treatment(P>0.05).The combination group exhibited higher visual scores and greater improvement in CAS compared to the monotherapy group(P<0.05),along with a higher rate of eyelid edema improvement(P<0.05).At 12 weeks,the monotherapy group had an effective rate of 65.0%,while the combination group had an effective rate of 66.7%.By week 24,the combined group achieved an effective rate of 80.0%.The over-all effectiveness at week 12 and treatment endpoints did not show any statistically significant differences between the two groups(P>0.05).No cases of leukopenia or severe infection occurred in the combination group.Conclusions The combination therapy of methylprednisolone and mycophenolate mofetil demonstrates efficacy,tolerability,and safety in the treatment of moderate to severe active GO.While the overall effectiveness of this combination may not surpass that of hormone therapy alone,it exhibits potential superiority in improving visual scores,eyelid congestion,eyelid edema,and eye movement pain when compared to hormone therapy alone.

Glyceryl phenylbutyrate(GPB)serves as a long-term management medication for Ornithine transcarbamylase deficiency(OTCD),effectively controlling hyperammonemia,but there is a lack of experience in using this medicine in China.This article retrospectively analyzes the case of a child diagnosed with OTCD at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,including a review of related literature.After diagnosis,the patient was treated with GPB,followed by efficacy follow-up and pharmacological monitoring.The 6-year and 6-month-old male patient exhibited poor speech development,disobedience,temper tantrums,and aggressive behavior.Blood ammonia levels peaked at 327 μmol/L;urine organic acid analysis indicated elevated uracil levels;cranial MRI showed extensive abnormal signals in both cerebral hemispheres.Genetic testing revealed de novo mutation in the OTC gene(c.241T＞C,p.S81P).Blood ammonia levels were approximately 43,80,and 56 μmol/L at 1,2,and 3 months after starting GPB treatment,respectively.During treatment,blood ammonia was well-controlled without drug-related adverse effects.The patient showed improvement in developmental delays,obedience,temperament,and absence of aggressive behavior.

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

The early response of plant auxin gene family Aux/IAA (auxin/indole-3-acetic acid) and its interaction with auxin response factor (ARF) are important pattern to regulate plant growth and development. This work identified 28 StoIAA and 24 StoARF members based on the whole genome data of the medicinal plant Senna tora L., which were classified into 10 and 8 subfamilies, respectively. Phylogenetic tree and collinearity analysis showed that S. tora has close evolutionary relationship with the IAA and ARF homologous genes of Glycine max, Medicago truncatula, and the segment duplication events dominate the expansion of StoIAA and StoARF. Gene structure analysis showed that the vast majority of StoIAA and StoARF contain characteristic conserved domain. Transcriptome data showed that StoIAAs and StoARFs were expressed in leaves, roots and seeds, some members had tissue specific expression. The StoIAA and StoARF promoter region most contain functional elements related to stress response, growth and development, hormone induction and secondary metabolism. In addition, gene expression analysis showed that many StoIAAs and StoARFs can quickly respond to drought and salt stress and exhibited same expression patterns under both stress condition. The yeast two-hybrid experiment confirmed that StoARF8 and StoARF10 exhibit varying degrees of interaction with multiple StoIAA proteins, respectively. The above results provide a basis for further biological functional analysis of the Aux/IAA and ARF gene family of S. tora.

Objective:To investigate whether long non-coding RNA(lncRNA) AW112010 can improve insulin resistance in aging adipocytes through the miR-204/POU2F2 signaling pathway.Methods:In vivo experiment: C57BL/6 mice were divided into young control group(4 months old) and aging model group(18 months old) based on body weight. The expression levels of AW112010, miR-204-5p, POU2F2, aging related indicators(p16, p21), and insulin signaling pathway genes [insulin receptor(INSR), insulin receptor substrate 1(IRS1), phosphatidylinositol kinase(PI3K), protein kinase B(AKT)] in epididymal adipose tissue were detected using real-time fluorescence quantitative PCR(RT-qPCR) and Western blotting. In vitro experiment: Using adriamycin(ADR) to induce 3T3-L1 aging adipocyte model, β-gal staining was used to observe cellular senescence, and miR-204 inhibitor and miR-204 mimic small interfering RNA were successfully constructed and transfected into 3T3-L1 adipocytes. Results:RT-qPCR and Western blot results showed that compared with the young group, the expression of AW112010 in the adipose tissue of aging mice was increased, while the expression of miR-204-5p was decreased. The expressions of POU2F2, p16, and p21 in the adipose tissue of aging mice were increased, while the expressions of INSR, IRS1, PI3K, GLUT4 mRNA and protein were decreased. The β-gal stainging results showed that the number of 3T3-L1 senescent adipocytes induced by ADR was significantly increased, and the expression levels of AW112010, POU2F2, p16, and p21 in ADR-induced senescent adipocytes were increased compared with the control group, while the expression levels of miR-204-5p, INSR, IRS1, PI3K, GLUT4 were decreased, and remaining glucose in the culture medium was increased. Compared with control, overexpression of miR-204 resulted in decreased expressions of aging indicators p16, p21, and target gene POU2F2 while the expressions of INSR and GLUT4 were increased.Conclusion:Upregulation of lncRNA AW112010 in adipocytes of aging mice may induce insulin resistance by targeting miR-204-5p/POU2F2/IRS1.
