Objective: To assess parental expectations for the development of children with autism spectrum disorder (ASD) and identify factors associated with these expectations, so as to provide references for improving rehabilitation outcomes and long term development in children with ASD. Methods: From June 2024 to January 2026, a total of 877 children with ASD and their parents were recruited from 27 rehabilitation institutions in Hefei. The children had been diagnosed by chief physicians at tertiary level hospitals. Demographic characteristics and data on parental expectations were collected by the Parental Expectations Questionnaire. Differences in parental expectations between groups were assessed using the Mann-Whitney U- test and Kruskal-Wallis H-test, and associated factors were examined using quantile regression. Results: The mean item score for overall parental expectations among parents of children with ASD was (4.55±0.47), and scores for all dimensions were higher than those among parents of typically developing children ( t =11.11-31.14, all P <0.01). Child age, school enrollment, and maternal personality were associated with daily living expectation scores, learning and special talents and strengths expectation scores, and special talents and strengths expectation scores, respectively ( H =6.16-8.18, all P <0.05). Parents of preterm children had higher expectations for social interaction, physical and mental well being, and daily living than parents of non-preterm children ( Z =-2.56, -2.48, -2.39, all P <0.05). Multivariate quantile regression analysis showed that children’s age was associated with the expected level of self care ability; school enrollment status was associated with the expected level of learning and specialty strengths; maternal personality was associated with the expected levels of social competence, physical and mental health, self care ability, and specialty strengths; parental age was associated with the expected levels of physical and mental health and specialty strengths; and parental educational attainment was associated with the expected level of self care ability ( β =-0.36-0.41, all P <0.05). Conclusion Parents of children with ASD in Hefei generally have high expectations for their children s development across the domains of learning, daily living, social interaction, and physical and mental well being.

Objective:To report the nationwide surveillance results of pathogenic profiles and antimicrobial resistance patterns of Gram-positive bloodstream infections in China in 2023.Methods:The clinical isolates of Gram-posttive bacteria from blood cultures were collected in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）during January to December 2023. Antimicrobial susceptibility testing was performed using the dilution method recommended by the Clinical and Laboratory Standards Institute（CLSI）. Statistical analyses were conducted using WHONET 5.6 and SPSS 25.0 software.Results:A total of 4 385 Gram-positive bacterial isolates were obtained from 60 participating center. The top five pathogens were Staphylococcus aureus（ n=1 544，35.2%），coagulase-negative Staphylococci（ n=1 441，32.9%）， Enterococcus faecium（ n=574，13.1%）， Enterococcus faecalis（ n=385，8.8%），and α-hemolytic Streptococci（ n=187，4.3%）. The prevalence of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）was 26.2%（405/1 544）and 69.8%（1 006/1 441），respectively. Notably，all Staphylococci remained susceptible to glycopeptide or daptomycin. Staphylococcus aureus demonstrated excellent susceptibility（>97.0%）to cephalobiol，rifampicin，trimethoprim-sulfamethoxazole，linezolid，minocycline，tigecycline，and eravacycline. No Enterococcus exhibiting resistance to linezolid were detected. Glycopeptide resistance was uncommon but more frequent in Enterococcus faecium（resistance to vancomycin and teicoplanin：both 1.7%）compared to Enterococcus faecalis（both 0.3%）. The detection rates of MRSA and MRCNS exhibited significant regional variations across the country（ χ2=17.674 and 148.650，respectively，both P<0.001）. No vancomycin-resistant Enterococci were detected in central China. Institutional comparison demonstrated higher prevalence of MRSA（ χ2=14.111， P<0.001）and MRCNS（ χ2=4.828， P=0.028）in provincial hospitals than that in municipal hospitals. Socioeconomic analysis identified elevated detection rates of both MRSA（ χ2=18.986， P<0.001）and MRCNS（ χ2=4.477， P=0.034）in less developed regions（per capita GDP

Objective:To report the results of bacterial resistant investigation collaborative system（BRICS）on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2023，and provide reference for clinical tretment of bloodstream infections and prevention and control of bacterial resistance.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of BRICS were collected during January 2023 to December 2023. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 were used to analyze the data.Results:During the study period，11 492 strains of Gram-negative bacteria were collected from 60 hospitals，of which 10 098（87.9%）were Enterobacterales and 1 394（12.1%）were non-fermentative bacteria. The top 5 bacterial species were Escherichia coli（50.0%）， Klebsiella pneumoniae（26.1%）， Pseudomonas aeruginosa（5.1%）， Acinetobacter baumannii complex（5.0%）and Enterobacter cloacae complex（4.1%）. The ESBL-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus mirablilis were 46.8%（2 685/5 741），18.3%（549/2 999）and 44.0%（77/175），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（76/5 741）and 15.0%（450/2 999）；32.9%（25/76）and 78.0%（351/450）of CREC and CRKP were sensitive to ceftazidime/avibactam combination，respectively. 94.7%（72/76）and 90.2%（406/450）of CREC and CRKP were sensitive to aztreonam/avibactam combination. Furthermore，57.9%（44/76）and 79.1%（356/450）were sensitive to imipenem/relebactam combination. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 64.6%（370/573），while more than 80.0% of CRAB complex was sensitive to tigecycline，eravacycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 17.0%（99/581）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of important Gram-negative bacteria resistance among different regions in China，with statistically significant differences in the prevalence of CREC，CRKP，CRPA and CRAB complex（ χ2=10.6，28.6，10.8 and 19.3， P<0.05）. The prevalence of ESBL-producing Escherichia coli， CREC，CRAB complex and CRKP were higher in provincial hospitals than those in municipal hospitals（ χ2=12.5，9.8，12.7 and 57.8，all P<0.01）. Conclusions:Gram-negative bacteria are the main pathogens causing bloodstream infections in China，and Escherichia coli is ranked in the top，while the trend of Klebsiella pneumoniae increases continuously with time. CRKP infection shows a slow upward trend，CREC infecton maintains a low prevalence level，and CRAB complex infection continues to exhibit a high prevalence rate. The composition and resistance patterns of pathogens causing bloodstream infections vary to some extent across different regions and levels of hospitals in China.

Objective:To explore the effect of preoperative intensive functional training on the balance and functional recovery of patients with knee osteoarthritis (KOA) receiving total knee arthroplasty (TKA).Methods:Sixty KOA patients were randomly divided into an outpatient group, a home-based group and a control group, each of 20. Before their TKAs, both the outpatient and home-based groups underwent intensive functional training for 4 weeks, while the control group did nothing special. After the TKA, all received 4 weeks of standardized postoperative rehabilitation training. Before any training, after the 4 weeks of preoperative training and 4 weeks after the TKAs, all of the subjects performed the timed up and go test (TUGT), and their joint range of motion (ROM) was recorded. They also completed the 30-second chair stand strength test (30sCST), and the 6-minute walk exercise endurance test (6MWT). KOA osteoarthritis indices (WOMACs) were also recorded.Results:After the 4 weeks of preoperative training, significant differences were observed in the trajectory length, elliptical area and TUGT times of both the outpatient and home-based groups. Four weeks after the TKAs, significant differences were observed in all of the measurements in all three groups, but the results of the outpatient and home-based groups were significantly better than those of the control group, on average. After the 4 weeks of postoperative training, there were significant differences between the outpatient and home-based groups in terms of the average knee flexion angle, knee extension angle, 30sCST and 6MWT results. There were significant differences among the 3 groups in all of the measurements 4 weeks after the TKAs, with those of the two training groups showing significantly better results than the control group. The pain scores, stiffness scores, function scores and total WOMAC scores had improved significantly compared with the control group, but the average function and total WOMAC scores of the outpatient group (24.25±2.38) and (35.41±3.02) were then significantly superior to the home-based group′s averages.Conclusions:Intensive preoperative functional training conducted in an outpatient clinic or at home can significantly improve the balance, lower limb strength, exercise endurance and symptoms of KOA patients after TKA.

Objective:To investigate the effect of progressive resistance training on inflammatory markers, motor function and quality of life in the elderly after total knee arthroplasty (TKA).Methods:This study was a randomized controlled trial. A total of 46 elderly patients aged≥60 years who underwent total knee arthroplasty in the Affiliated Hospital 6 of Nantong University from January 2023 to June 2024 were selected and divided into experimental group and control group by computer random number method (23 cases in each group). The control group received routine rehabilitation management intervention, progressive resistance training was added to the experimental group on the basis of the control group, and all patients were intervened for 4 weeks. Interleukin-6 (IL-6), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), 30-Second Chair Stand Test (30sCST), Knee Society Score (KSS), and World Health Organization Quality of Life Scale-Brief Form Questionnaire (WHOQOL-BREF) scores were measured at 1 day before operation, 2 weeks and 4 weeks after operation, and were compared respectively.Results:At 2 and 4 weeks after operation, the levels of IL-6 [(22.44±2.17) and (9.91±1.41) pg/ml], CRP[(19.61±2.20) and (3.17±0.40) mg/L] and ESR[(44.85±3.78) and (28.28±3.31) mm/1 h] in the experimental group were significantly lower than those in control group [IL-6: (24.65±1.77) and (11.35±1.67) pg/ml, CRP: (23.24±2.69) and (4.15±0.45) mg/L and ESR: (48.54±3.66) and (34.60±2.98) mm/1 h](all P<0.05). At 2 and 4 weeks after operation, the 30sCST[(9.87±0.92) and (11.83±1.03) times], clinical scores of KSS[(48.44±3.13) and (71.09±3.30) points], functional scores of KSS[(40.44±3.96) and (69.35±4.07) points] in the experimental group were significantly higher than those in control group [30sCST: (9.30±0.70) and (10.52±0.79) times, clinical scores of KSS: (46.17±2.86) and (67.00±2.89) points, functional scores of KSS: (38.91±3.68) and (66.30±5.05) points](all P<0.05). At 2 weeks after operation, the scores of physical health, mental health and social relations in the WHOQOL-BREF of the experimental group [(16.96±1.02), (17.96±1.46) and (6.74±0.62) points], which were significantly higher than those in the control group [(16.09±1.08), (17.14±1.12), (6.44±0.51) points](all P<0.05). There was no significant difference in the environmental condition score between the two groups. At 4 weeks after operation, the scores of physical health, mental health, social relations and environmental conditions in WHOQOL-BREF of the experimental group [(22.09±1.81), (22.17±2.19), (12.09±1.28) and (33.91±2.26) points] were significantly higher than those in the control group [(19.65±1.80), (20.39±1.95), (10.17±1.30), (31.96±2.51) points] (all P<0.05). Conclusion:Progressive resistance training can effectively reduce the inflammatory response in the elderly after total knee arthroplasty, enhance lower limb muscle strength and knee joint function, and improve the quality of life.

Objective:To investigate the pathogenetic characteristics of clinical isolates of Streptococcus suis in Henan Province from 2020 to 2023. Methods:Eight clinical isolates of S. suis in Henan Province from 2020 to 2023 were identified using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) and real-time fluorescence polymerase chain reaction (PCR). Serotype and virulence genes were detected by the serum agglutination test and PCR, and antibiotic susceptibility was evaluated using the microbroth dilution method. Multilocus sequence typing (MLST), minimum core genome (MCG), identification of antibiotic resistance genes, and core genome single nucleotide polymorphism (cgSNP) analysis were conducted using whole genome sequencing. Results:The results showed that eight S. suis strains isolated from humans were mainly serotype 2 (75.0%), while the rest were serotype 14 (25.0%). ST353 (62.5%) was the predominant genotype, followed by ST1 (25.0%) and ST7 (12.5%). All isolates belonged to the MCG1 group. The virulence genotypes of these isolates were primarily mrp(NA2)/ sly+/ ef+/ gapdh+(75.0%), while the remaining were mrp(EU)/ sly+/ ef+/ gapdh+(25.0%). These isolates carried tetracycline, macrolide, lincosamide and aminoglycoside resistance genes, and their resistance rates to tetracycline, erythromycin and clindamycin were 100.0%, 87.5% and 87.5%, respectively, and 62.5% strains were intermediate-resistant to penicillin. The cgSNP analysis indicated that these isolates were closer to the isolates from Guangdong, Zhejiang and Guangxi Provinces, with five ST353 strains and one ST7 strain belonging to Clade Ⅰ, and two ST1 strains belonging to Clade Ⅱ. Conclusion:The human isolates of S. suis in Henan Province are mainly ST353, harboring multiple virulence and antibiotic resistance genes.

The treatment landscape for metastatic renal cell carcinoma(mRCC)has evolved rapidly over the past two decades with the introduction of targeted therapies and novel immune checkpoint inhibitors.Among these developments,cytoreductive nephrectomy(CN)remains a controversial and unresolved issue,with its survival benefits being questioned compared to systemic therapy(ST).The role and optimal timing of CN in the context of modern systemic treatment for mRCC remain unclear.Additionally,there is still no well-defined consensus on patient selection for CN.Therefore,this article provides a concise review of current evidence regarding CN in mRCC,incor-porating the latest renal cancer management guidelines.We focus particularly on optimal surgical timing,candidate patient selection,and the therapeutic value of metastasectomy.Furthermore,we examine the current role of CN in metastatic non-clear cell renal cell carcinoma and explore its evolving clinical applications and future prospects in mRCC treatment.

Objective To conduct a rapid health technology assessment(rHTA)of the efficacy,safety,and cost-effectiveness of tirzepatide for the treatment of type 2 diabetes mellitus(T2DM),and to provide evidence for clinical medication.Methods PubMed,Web of Science,Embase,Cochrane Library,WanFang Data,CNKI databases,and health technology assessment(HTA)websites were searched to collect systematic reviews/Meta-analysis,pharmacoecomic literature and HTA reports of tirzepatide in the treatment of T2DM from inception to February 28,2025.Two researchers independently conducted literature screening,data extraction,and quality assessment,and then summarized and analyzed the results.Results A total of 13 articles were included,comprising 2 HTA reports,8 systematic reviews/Meta-analyses,and 3 pharmacoeconomic studies.In terms of efficacy,tirzepatide outperformed placebo or other antidiabetic drugs in reducing glycated hemoglobin(HbA1c),increasing the rate of HbA1c＜7％,lowering blood glucose,and reducing weight.The antihyperglycemic and weight-loss effects of tirzepatide were dose-dependent,and it also had certain advantages in reducing the risk of cardiovascular events and renal composite endpoint events.Regarding safety,the incidence of gastrointestinal adverse events in the tirzepatide group was higher than that in the placebo group and the insulin group,mainly manifested as diarrhea,nausea,and vomiting.However,it did not increase the risk of serious gastrointestinal adverse events,nor did it increase the risk of hypoglycemia and pancreatitis.In terms of cost-effectiveness,tirzepatide had cost-utility and cost-effectiveness advantages compared with semaglutide and other antidiabetic drugs.Conclusion Compared with other antidiabetic drugs,tirzepatide has better efficacy,safety,and cost-effectiveness in the treatment of T2DM.

Objective : To investigate the role of enhancer of zeste homolog 2(EZH2)-trimethylated lysine 27 of histone H3(H3K27me3) axis in the dedifferentiation of thyroid cancer and its clinical value as a potential target for the treatment of anaplastic thyroid cancer(ATC). Methods : Immunohistochemical SP method was used to detect the expression of EZH2, H3K27me3, paired box gene 8(PAX8), thyroglobulin(TG) and thyroid transcription factor 1(TTF1) in ATC and papillary thyroid carcinoma(PTC) and their adjacent tissues. The relationship between EZH2 and thyroid differentiation markers(PAX8, TTF1, TG) was further analyzed by gene expression omnibus(GEO) database. ATC cell lines 8305C and BHT-101 were culturedin vitro. Real-time reverse transcription PCR(RT-qPCR) was used to detect the expression of thyroid differentiation markers(TTF1, PAX8) mRNA in ATC cell lines treated with EZH2 inhibitor(GSK126), and evaluate the potential therapeutic effect of GSK126in vitro. The effects of GSK126 and BRAF inhibitor vemurafenib on the proliferation of ATC cell lines were observed by cell proliferation assay. Results : The expression of EZH2 in ATC tissues was significantly higher than that in papillary thyroid carcinoma and adjacent tissues(P<0.05). The expression of H3K37me3 in ATC tissues was significantly lower than that in PTC tissues(P<0.05). EZH2 was negatively correlated with PAX8 and TG expression levels, but not with TTF1 expression level.In vitroexperiments, GSK126 could reverse the expression of thyroid differentiation markers PAX8 and TTF1 in ATC cell lines. GSK126 combined with BRAF inhibitor vemurafenib could significantly inhibit the growth of ATC cell lines. Conclusion The EZH2-H3K27me3 axis plays an important role in regulating thyroid specific markers, and the inhibition of EZH2 by small molecular compounds is a promising target for ATC treatment in the future.

Objective To investigate the distribution and antimicrobial resistance profiles of clinical isolates in Xi'an No.3 Hospital from 2019 to 2023.Methods Clinical isolates were collected from January 1,2019 to December 31,2023.Antimicrobial susceptibility testing was carried out according to a unified protocol of China Antimicrobial Resistance Surveillance Network using Kirby-Bauer method or automated systems.The data were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2023.Results A total of 6 621 clinical isolates were collected from 2019 to 2023,including 1 569(23.7％)strains of Gram-positive bacteria and 5 052(76.3％)strains of Gram-negative bacteria.The prevalence of methicillin-resistant S.aureus,S.epidermidis and other Staphylococcus species(except SS.pseudintermedius and S.schleiferi)was 39.0％,62.3％,and 74.4％,respectively.Methicillin-resistant strains showed much higher resistance rates to most of other antimicrobial agents than methicillin-sensitive strains.No Staphylococcus strains were found resistant to vancomycin or linezolid.E.faecium strains demonstrated much higher resistance rates to most antimicrobial agents tested than E.faecalis.The prevalence of linezolid-resistant E.faecalis and vancomycin-resistant E.faecium was 0.9％and 0.4％,respectively.The prevalence of penicillin-nonsusceptible strains(PISP+PRSP)was 5.8％in nonmeningitis S.pneumoniae isolates.The prevalence of ESBL-producing E.coli,K.pneumoniae,and P.mirabilis in Enterobacterales was 48.5％,37.8％,and 47.2％,respectively.Among Enterobacterales strains,K.pneumoniae had the highest resistance rate to imipenem(18.2％)and meropenem(17.9％).Other Enterobacterales were highly sensitive to carbapenems.The resistance rates of P.aeruginosa to imipenem and meropenem were 22.5％and 19.5％,respectively.The resistance rates of A.baumannii to imipenem and meropenem were 65.0％and 71.6％,respectively.Conclusions Antibiotic resistance is still serious in this hospital.Nearly half of the strains of E.coli,K.pneumoniae and P.mirabilis produced ESBLs.K.pneumoniae and A.baumannii showed high resistance rates to carbapenems.Antimicrobial resistance surveillance should be performed appropriately.Relevant departments need to strengthen cooperation to curb the spread of drug-resistant bacteria.
