Objective:To understand the status of intestinal helminth infections in Lunan area of Shandong Province (Jining City, Rizhao City, Linyi City, Heze City, and Zaozhuang City), and provide scientific basis for formulating parasitic disease prevention and control strategies.Methods:From 2016 to 2023, a stratified sampling method was used to conduct surveillance in 33 counties (cities, districts, hereinafter referred to as counties) in Lunan area of Shandong Province. Each county was divided into five areas (east, south, west, north, and center), with one administrative village (community) selected from each area. And ≥200 permanent residents (aged ≥3 years old, having lived locally for ≥6 months) were sampled from each village (community), and one stool sample was collected from each participant. The Kato-Katz method (two slides per sample) was used for parasite detection, and the results were analyzed.Results:From 2016 to 2023, a total of 49 436 people were surveyed, including 23 861 males and 25 575 females, with an age range of 3 - 105 years old. The testing identified 687 intestinal helminth infections, with an overall infection rate of 1.39%. The predominant infection was whipworm (582 cases), with an infection rate of 1.18%; followed by roundworm and hookworm, with infection rates of 0.13% (62 cases) and 0.05% (23 cases) respectively; other types of helminths ( Clonorchis sinensis and pinworm) totaled 20 cases, with an infection rate of 0.04%. From 2016 to 2023, the annual intestinal helminth infection rates were 2.76% (201/7 292), 0.90% (56/6 327), 0.84% (52/6 200), 1.70% (124/7 282), 1.23% (88/7 133), 1.45% (104/7 150), 0.34% (17/5 058), and 1.46% (45/3 084), showing an overall downward trend (χ 2trend = 42.40, P < 0.001). The ≥60 age group had the highest intestinal helminth infection rate (2.39%, 323/13 489), while the 30 - 39 age group had the lowest rate (0.68%, 48/7 016). There was statistically significant difference in infection rates among different age groups (χ 2 = 172.25, P < 0.001). There was no statistically significant difference in infection rates between genders (χ 2 = 0.03, P = 0.862). Farmers had the highest infection rate (1.69%, 560/33 118), with statistically significant differences among different occupational groups (χ 2 = 64.88, P < 0.001). Those with primary school education or below had the highest infection rate (1.82%, 445/24 469), with statistically significant differences among different education levels (χ 2 = 64.93, P < 0.001). Conclusions:In Lunan area of Shandong Province, whipworm is the predominant intestinal helminth infection, with elderly people being the high-risk group. Although the intestinal helminth infection rate in this region remains at a low level, there is still a risk of transmission. Continuous surveillance is needed, along with strengthened prevention and control measures for key populations.

Objective:To investigate the anatomical feasibility of the endoscopic transorbital approach (ETOA) to the orbital apex and lateral middle cranial fossa, to identify stable and recognizable surgical landmarks under endoscopic visualization, and to provide morphometric data for preoperative planning and intraoperative navigation.Methods:Stepwise anatomical dissection was performed on five formalin-fixed cadaveric heads and one fresh arterially injected cadaveric specimen to simulate the ETOA using a 0° endoscope. Key structures and their anatomical relationships were observed and recorded. Additionally, high-resolution CT scans of 50 adults were retrospectively analyzed. Three-dimensional reconstructions and measurements were performed using Mimics 17.0 software. Spatial validation was performed using 17 dry skulls to verify the consistency and reliability of osseous anatomical landmarks.Results:Cadaveric dissection identified the meningo-orbital band, superior orbital fissure, optic canal, foramen rotundum, and foramen ovale as reliable surgical landmarks for the ETOA. A topographic map of the surgical region was established based on the endoscopic view. CT measurements revealed the following distances (Mean±SD): the midpoint of the supraorbital rim to the foramen rotundum (57.31±3.59) mm and foramen ovale (71.46±3.42) mm; the lateral orbital rim to the lateral edge of the superior orbital fissure (37.38±2.52) mm; the distance from the superior orbital fissure to the optic canal (9.98±1.49) mm; and the distance from the anterior ethmoidal artery to the optic canal (19.98±2.05) mm. These measurements were consistent with dry skull data, indicating that these osseous landmarks had stable spatial relationships and were suitable for intraoperative localization.Conclusions:The ETOA provides favorable anatomical accessibility and clinical feasibility for lesions involving the orbital apex and lateral skull base. Key osseous structures demonstrate high identifiability and stable spatial relationships, serving as critical references for intraoperative navigation and preoperative pathway planning. The quantitative anatomical framework established in this study provides critical morphometric support for minimally invasive surgery targeting lesions in this region.

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 compare the mechanical properties between our self-designed axially controlled compression spinal rod (ACCSR) and conventional spinal rod (CSR) for lumbar spondylolysis (LS).Methods:This study selected 36 ACCSRs (the ACCSR group) and 36 CSRs (the CSR group), both of which were in a diameter of 6.0 mm and manufactured in the same batch. They were subjected respectively to biomechanical tests of spinal rod and pedicle screw-rod internal fixation system. In spinal rod tests: the stiffness and yield load of the spinal rods were calculated using four-point bending tests ( n=7) and comparisons were made between the 2 groups; spinal rod fatigue tests ( n=8) recorded the successful compression loads after 2.5 million cycles of loading and compared them with the maximum force at the isthmus of a normal adult's unilateral lumbar spine (198.72 N). In tests of the pedicle screw-rod internal fixation system, the axial compression tests ( n=7) measured the axial gripping capacity, the axial torsion tests ( n=7) the torsional gripping capacity, and the lateral compression tests ( n=7) the stiffness and yield load of pedicle screws in the 2 groups respectively. Results:The stiffness [(1,543.37±61.41) N/mm] and yield load [1,338.57 (1,282.00, 1,353.80) N] of ACCSR group were significantly smaller than those of CSR group [(3,797.63±156.15) N/mm and 4,059.95 (3,813.80, 4,090.89) N] ( P<0.05). The spinal rod fatigue tests showed that the respective loads of CSR and ACCSR passing the 2.5 million fatigue tests were 640.00 N and 320.00 N, both larger than the maximum force at the unilateral lumbar isthmus of a normal adult (198.72 N). There were no significant differences between the ACCSR group and the CSR group in the axial gripping capacity and torsional gripping capacity, as well as in stiffness and yield load of screws between the 2 groups ( P>0.05). Conclusions:In fixation of LS, although the yield load, stiffness and fatigue resistance of ACCSR are inferior to those of CSR, the biomechanical properties of the two sets of pedicle screw-rod internal fixation system are comparable. The fatigue resistance of ACCSR can meet the stress requirements of the normal human isthmus.

Objective:To investigate the current status of vocational training for pediatric clinical research coordinators (CRC), and discuss the construction of base-based pediatric CRC training, and to promote the ability of pediatric CRCs.Methods:From July 25 to October 16, 2023, an anonymous self-designed questionnaire survey was conducted through the Wenjuanxing platform to investigate the current situation of pediatric CRC vocational training and base training needs. The data were collated using Excel. Categorical data were described as numbers and percentages.Results:A total of 328 usable questionnaires were returned. Only 7.62% (25 people) believed that existing CRC training was sufficient and could meet actual work needs; 4.88% (16 people) responded that there was no training; 46.34% (152 people) believed that the training was insufficient to support actual work needs; 87.50% (287 people) believed that continuous CRC training was needed; 46.95% (154 people) preferred experienced CRCs for teaching, who should have at least 3 years of CRC work experience; and 46.95% (154 people) preferred a duration of 3 months for CRC training. The preferred training methods were: practice under the direction of experienced CRCs (90.85%, 298 people), step-by-step teaching of practical skills (88.41%, 290 people), case analysis and discussion (87.20%, 286 people), process simulation (83.23%, 273 people), and lecture-based teaching (76.52%, 251 people). The preferred post-training assessment methods were: case analysis (76.52%, 251 people), operation simulation (74.09%, 243 people), process simulation (73.17%, 240 people), written examination (66.16%, 217 people), and interview (63.72%, 209 people).Conclusions:The current pediatric CRC training is not enough to meet actual work needs. It is urgent to develop and promote a CRC training system that can meet work needs, laying the foundation for the construction of pediatric clinical research ecology in China.
