Methods: Sixty-two patients (2014–2019) were divided into the SC (n=32) and PC (n=30) groups. Clinical outcomes were evaluated using the Visual Analog Scale (VAS), modified Japanese Orthopedic Association (mJOA) score, and Neck Disability Index (NDI). Radiological parameters, including cervical lordosis (CL), fused segment angle (FSA), and disc height (DH), were assessed. Cage subsidence, adjacent segment degeneration (ASD), and other complications were also documented. The relationship between postoperative radiological changes and symptoms was also analyzed. Results: Both groups showed significant improvement in symptoms, with fusion achieved in all surgical segments. The SC group had a shorter operative time and reduced intraoperative blood loss. However, the SC group had a higher subsidence rate (16.7% vs. 5.6%, p=0.017). The PC group maintained better cervical alignment in terms of CL, FSA, and DH (p<0.05), with an increased incidence of dysphagia and ASD (p<0.05). Spearman correlation analyses showed that neither CL nor FSA loss at the 5-year follow-up was significantly associated with improvements in the mJOA, VAS, and NDI scores (p>0.05) in either group. Regression analyses indicated that subsidence or loss of lordosis did not correlate with the degree of postoperative symptoms (p<0.05). Conclusions Both SC and PC achieved sustained pain relief, neurological improvement, and solid fusion in three-level ACDF at the 5-year follow-up. SC demonstrated significant advantages in reducing dysphagia and ASD, while PC better maintained cervical alignment and segmental stability. Patient-specific factors should be used to guide implant selection. Further multicenter studies are required to validate these findings.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

The clinical practice guidelines for Chinese patent medicines （CPM） provide reference for the selection of national drug catalogs， the formulation of prescription collections in medical institutions， and the clinical use of CPM， constituting an important part of traditional Chinese medicine （TCM） guidelines. As a crucial part of Chinese drug supply guarantee system， CPM plays an important role in the treatment， prevention， and healthcare of many disease categories， whereas the application of CPM has problems of misuse and even abuse. To standardize the application of CPM， a research team at Zhejiang Chinese Medical University developed the Reporting Items for Practice Guidelines in Healthcare for Chinese Patent Medicines （RIGHT for CPM） based on the RIGHT checklist framework. The RIGHT for CPM checklist gathers key information from published CPM guidelines， existing TCM reporting checklists， and the RIGHT checklist and its extensions to form an initial pool of reporting items. Seventeen experts from different disciplines were invited to conduct two rounds of Delphi surveys， and the final checklist was reviewed and approved for publication by 18 leading experts in TCM research and guideline reporting from China and abroad. The RIGHT for CPM checklist adds 16 sub-items and revises 2 sub-items on the basis of the RIGHT checklist， highlighting the characteristics of CPM guideline reporting. It considers CPM selection and inclusion criteria， policy access， indications and symptoms， drug combination instructions， drug use in special populations， precautions， and recommendations of Western medical physicians， among others. This can further improve the quality and transparency of CPM guideline reporting， promote standardized reporting of CPM guidelines， and facilitate the rational clinical use of CPM. This article interprets the development process of the RIGHT for CPM checklist and the items that highlight the characteristics of CPM guidelines， with a view to promoting the application of the RIGHT for CPM checklist.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

Objective:To observe the effect of different degrees of decentration and tilt on the optical quality of the intraocular lenses (IOLs) with different focus designs.Methods:The UV 3300 PC UV-visible spectrophotometer was employed to measure the spectral transmittance of the monofocal IOL CT ASPHINA 509M (509M), bifocal IOL AT LISA 809M (809M), and trifocal IOL AT LISA Tri 839MP (839MP) within Zeiss MICS platform with a refractive power of + 20 D. The modulation transfer function (MTF) values at a spatial frequency of 50 lp/mm along with MTF curves and United States Air Force (USAF) resolution test charts for each IOL at the focal point were measured at apertures of 3.0 mm and 4.5 mm using the in vitro optical quality testing system OptiSpheric IOL R&D under centered, decentered (0.3, 0.5, 0.7, 0.9 and 1.1 mm) and tilted (3°, 5°, 7°, 9° and 11°) conditions. Results:All three IOLs filtrated the ultraviolet (UV) spectrum below 400 nm.When each IOL was in the centered position, at the 3.0 mm aperture, the MTF values were 0.772 at the far focus of the monofocal IOL 509M, 0.467 and 0.282 at the far and near focus of the bifocal IOL 809M, and 0.416, 0.147, and 0.229 at the far, intermediate, and near focus of the trifocal IOL 839MP, respectively.Whereas at the 4.5 mm aperture, the monofocal IOL 509M MTF value at the far focus was 0.664, the bifocal IOL 809M MTF values at the far and near focus were 0.506 and 0.264, and the trifocal IOL 839MP MTF values at the far, intermediate, and near focus were 0.392, 0.107, and 0.210, respectively.Among the three centered IOLs, the 509M demonstrated the highest MTF value at the far focus, followed by the 809M and then the 839MP; at the near focus, the MTF value of the 809M surpassed that of the 839MP.For decentration and tilt, the difference in MTF values of the three IOLs at the far and near focus was consistent with the differences observed when they were centered.At the same degree of decentration and tilt, all three IOLs exhibited superior optical quality at the 3.0 mm aperture compared to the 4.5 mm aperture.The optical quality of all three IOLs exhibited an overall decline as decentration and tilt increased.All three IOLs demonstrated a decrease in optical quality at the decentration of 0.3 mm or the tilt of 5°.Conclusions:The IOLs within the Zeiss MICS platform design exhibits identical spectral transmittance and UV filtering properties.Among the three IOLs, when centered, the 509M, the 839MP, and the 809M exhibit superior optical quality at the far, intermediate, and near focal points, respectively.Under decentered and tilted conditions, the 509M and the 809M demonstrate better resistance against decentration and tilt, respectively, at both far and near focuses.Additionally, all three IOLs demonstrate better optical quality at smaller apertures, given equivalent degrees of decentration or tilt.However, the optical quality at each focal point of the three IOLs decreases compared to the centered position when subjected to a decentration of 0.3 mm or a tilt of 5°.

Objective To explore the policy foundations of early family education and rehabilitation support systems for children with developmental disabilities aged zero to three years,based on the International Classification of Functioning,Disability and Health(ICF),and to construct a comprehensive,whole-person and whole-lifecycle support system integrating early childhood education and rehabilitation services for families;and to propose corresponding sys-tem architecture,construction pathways and governance models.Methods Policy documents were compared,which were related to children's rehabilitation from the World Health Orga-nization,early education guidelines for children with disabilities from the United Nations Educational,Scientific and Cultural Organization,the U.S.Individuals with Disabilities Education Act,European Union children's reha-bilitation policies,and the"14th Five-Year Plan"from China Disabled Persons'Federation.The related policy frameworks and key content of early family education and rehabilitation were reviewed,and the composition,implementation pathways and governance models of the support system were systymatically analyzed.Results The support system consisted of early screening and assessment,family education and parent training,counsel-ing and personalized education and rehabilitation support,community support and resource integration,and re-mote digital support platforms.The study proposed the implementation pathways for five systems,including early screening and assessment,family education and parent training,counseling and personalized rehabilitation support,community support and resource integration,and remote digital support platforms.It emphasized gover-nance mechanisms such as multidisciplinary collaboration,interdepartmental coordination and support from re-mote digital platforms to build a continuous service chain from standardized assessments to interdepartmental collaboration.Conclusion The person-centered approach and whole life span development concept based on the ICF model,as well as the guiding principles of the health services continuum,provide systematic theoretical and policy support for early childhood education and rehabilitation for children with developmental disabilities aged zero to three years.Through multidisciplinary collaboration,interdepartmental coordination and the application of digital platforms,a scientific,continuous and child-centered support system can be built.This not only facilitates early detection and precise intervention but also promotes multi-party collaboration among families,communities and profes-sional institutions.It will further integrate disability prevention,rehabilitation and healthcare services,thereby im-proving children's functional abilities and family quality of life.

Objective To understand the distribution and antimicrobial resistance profiles of bacterial strains isolated from blood cultures at Yunyang County People's Hospital from 2019 to 2023.Methods The data of bacterial isolates from blood samples and the results of antimicrobial susceptibility testing were analyzed retrospectively from 2019 to 2023 at Yunyang County People's Hospital.Results A total of 3 789 bacterial strains were isolated from blood culture,including 1 931(51.0％)strains of Gram negative bacteria and 1 858(49.0％)strains of Gram positive bacteria.Coagulase negative Staphylococcus(33.3％),Escherichia coli(25.4％),Klebsiella pneumoniae(13.7％),Staphylococcus aureus(9.9％),and Enterobacter cloacae(1.8％)were the top five bacterial pathogens.Antimicrobial susceptibility testing showed that the prevalence of methicillin-resistant strains was 27.1％in S.aureus,34.5％in S.epidermidis,and 49.9％in other coagulase-negative Staphylococcus.Methicillin resistant strains(MRSA,MRSE,and other MRCNS)showed significantly higher resistance rates to most antibiotics than corresponding methicillin-susceptible strains(MSSA,MSSE,and other MSCNS).No staphylococcal isolates were resistant to vancomycin,teicoplanin,linezolid,or tigecycline.Enterococcus faecium showed significantly higher resistance rate to antibiotics than Enterococcus faecalis.No enterococcal strains were resistant to vancomycin,teicoplanin,linezolid,or tigecycline.No streptococcal isolates were found resistant to vancomycin or linezolid.Serratia marcescens strains had a resistance rate of 25.0％to carbapenems.All other Enterobacterales species showed a resistance rate of less than 10.0％to carbapenems.No Enterobacterales isolates were found resistant to tigecycline.The resistance rates of P.aeruginosa to imipenem and meropenem were 5.7％and 3.8％,respectively.No P.aeruginosa isolates were found resistant to colistin.The resistance rates of Acinetobacter baumannii to imipenem and meropenem were 41.4％and 38.0％,respectively.Conclusions The proportion of Gram negative bacteria is slightly higher than that of Gram positive bacteria in the bacterial isolates from blood samples at Yunyang County People's Hospital.The prevalence of MRSA and MRCNS is relatively high,while A.baumannii and S.marcescens showed high resistance rates to carbapenems.Antimicrobial resistance surveillance should be strengthened for the bacterial isolates from blood samples in order to learn the changing resistance profiles,use antibiotics reasonably,and prevent the spread of drug-resistant bacteria.

Objective:To explore the clinical application value of multimodal Magnetic Resonance Imaging(MRI)in cognitive impairment related to Cerebral Small Vessel Disease(CSVD).Methods:This study was a retrospective analysis of 60 CSVD patients,who were divided into cognitive impairment group(n=32)and normal group(n=28)based on Montreal Cognitive Assessment scale(MoCA).Compare the general information and MRI parameters of two groups of patients,use correlation analysis and logistic regression analysis to investigate the relationship between MRI parameters and cognitive dysfunction,and use receiver operating characteristic curve(ROC)to explore the value of MRI parameters in diagnosing cognitive dysfunction in cerebral small vessel disease.Results:Compared with the cognitively normal group,the cognitive impairment group had older age,higher apparent diffusion coefficient(ADC),lower anisotropy score(FA),and an overall increase in microbleeds(P＜0.05).Age(r=-0.510),ADC value(r=-0.591),and overall number of microbleeds(r=-0.369)were significantly negatively correlated with MoCA score(P＜0.05),while FA value(r=0.262)was significantly positively correlated with MoCA score(P＜0.05).The logistic regression results indicate that age,overall microbleeds,ADC value,and FA value are influencing factors for cognitive impairment in patients with cerebral small vessel disease.ROC curve analysis showed that the combination of age,ADC,FA,and microbleeds significantly improved diagnostic efficacy(AUC=0.990,95％CI=0.974-1.000).Conclusion:The joint analysis of multimodal MRI parameters can provide important imaging evidence for the early identification of cognitive dysfunction in CSVD.
