Objective: To identify research priorities on physical and mental comorbidity among children and adolescents in Zhejiang Province, so as to provide a theoretical base for improving their physical and mental health. Methods: In May 2025, 77 experts in the fields of health and education from 11 cities in Zhejiang Province were selected by convenient sampling method to participate in the first round of expert consultation. In June, 2025, snowball sampling was used to expand to 194 experts for the second round of consultation, and it was convenient to select 21 students from primary schools to high schools in Zhejiang Province and 29 parents to empower the evaluation criteria. It applied the Child Health and Nutrition Research Initiative (CHNRI) method in a structured process, which encompassed the definition of the research field, generation of research ideas, scoring, and quantitative ranking of priorities. Research ideas were evaluated against 6 predefined criteria: effectiveness, safety, answerability, feasibility, sustainability, and scientific significance. Results: After 2 rounds of structured consultations, 81 research ideas on physical and mental comorbidity among children and adolescents were established and classified into 7 subthemes: epidemiological characteristics and influencing factors, optimization of primary service systems and policies, comprehensive intervention strategies for physical and mental comorbidity, biological mechanisms and clinical research, the impact of education and environment on physical and mental health, special populations and social support, and digital and technology driven disease prevention and intervention. The top 10 research priorities primarily centered on the subdomain of "epidemiological characteristics and influencing factors" (5 items). The top 3 research priorities were "the association between outdoor activity duration and the incidence of common diseases (including mental disorders) among children and adolescents" "the impact of outdoor activity duration on the physical and mental health of adolescents" "comprehensive intervention strategies for myopia, obesity, and their comorbidities among children and adolescents". Conclusion The framework of priority issues in the field of psychosomatic comorbidity of children and adolescents in Zhejiang Province based on CHNRI method provides a reference for optimizing the allocation of provincial research resources.

Atherosclerosis (AS) remains the core pathological basis underlying the high incidence and high rates of mortality and disability associated with cardiovascular disease (CVD) worldwide. Its essence is not merely lipid deposition, but rather an immune-mediated disease of the vascular wall characterized by an interplay of lipid metabolism disorders and chronic inflammation, with damage to vascular endothelial cells serving as the initiating event. As the disease progresses, it involves complex synergistic interactions among various cellular components, including endothelial cells, macrophages, and inflammatory cells, ultimately leading to plaque formation, instability, and even fatal thrombotic events. In recent years, the central driving role of lipid metabolic reprogramming in the progression of AS has garnered increasing attention from the scientific community. Among the vast array of lipid molecules, long-chain fatty acids (LCFAs) have become a primary focus of research due to their exceptional physiological functions. Traditional views have primarily emphasized the basic physiological functions of LCFAs: serving as highly efficient energy substrates through mitochondrial β-oxidation and acting as key structural components of cellular phospholipid membranes. However, emerging evidence clearly indicates that the functions of LCFAs extend far beyond those of mere metabolic fuel. They also act as potent bioactive signaling molecules, playing an indispensable multidimensional role in the pathogenesis of AS. Equally noteworthy and representing a paradigm shift in cardiovascular research is the emerging theory of the “gut-heart axis”. This theoretical framework views the human gut microbiota—comprising trillions of microorganisms—as a critical and metabolically active “bioreactor”. A wealth of clinical and multi-cohort epidemiological studies have conclusively demonstrated that imbalances in the composition and function of the gut microbiota are highly correlated with the clinical risk and severity of AS. Within this axis, the gut microbiota serves as the primary processing hub for dietary lipids. It actively participates in the digestion and biochemical remodeling of LCFAs, thereby altering their saturation and chemical structure and generating a wide variety of gut microbial metabolites. The effects of these gut-derived lipid metabolites extend far beyond the local intestinal microenvironment. Upon entering the bloodstream, these circulating microbiota metabolites act as endocrine signals. Given the extreme complexity of the underlying mechanisms, a comprehensive elucidation of the synergistic and bidirectional interactions between LCFAs and the gut microbiota in vascular pathology is particularly urgent. Therefore, this article aims to provide a systematic review of the multidimensional regulatory mechanisms of LCFAs and their associated gut microbiota metabolites in the onset, progression, and clinical manifestations of AS. By thoroughly exploring the interaction patterns within the “LCFAs-gut microbiota-AS” triad, this review seeks to fundamentally expand our understanding of the pathogenesis of CVDs. More importantly, translating these mechanistic insights into clinical practice holds tremendous promise. We hope to provide a solid theoretical foundation for the future development of novel AS prevention and treatment strategies based on non-traditional approaches. These include precision nutritional interventions (i.e., dietary lipid intake plans tailored to an individual’s unique microbiome profile) and targeted microbiome modulation therapies (such as next-generation probiotics, prebiotics, or specific metabolite supplements). Targeting the gut as a “reactor” to treat vascular wall lesions represents a promising direction for future cardiovascular medicine.

ObjectiveTo explore the impact of comprehensive vocational rehabilitation on quality of life and return-to-work outcomes for individuals with mild work-related disability. MethodsA longitudinal observational study was conducted. A total of 343 work-injured employees receiving comprehensive vocational rehabilitation intervention in Guangdong Work Injury Rehabilitation Hospital from June, 2023 to December, 2024 were selected. The 36-item Short Form Health Survey (SF-36) was adopted to assess their health-related quality of life at admission and discharge. All subjects were followed up within one year after discharge to collect their return-to-work status. The differences in each dimension score of SF-36 among patients with different return-to-work outcomes (return to original post, transfer to new post and non-return to work) were compared, and the independent influencing factors of return-to-work outcomes were identified. ResultsComprehensive vocational rehabilitation intervention significantly improved the scores of physical functioning (PF), role-physical (RP) and role-emotional (RE) among work-injured employees (P < 0.05). At discharge, compared with patients who failed to return to work, patients returning to original post obtained significantly higher scores in PF, RP, bodily pain (BP), general health (GH), vitality (VT), social functioning (SF) and mental health (MH), patients transferred to new post achieved significantly higher scores in PF, BP, GH and SF (P < 0.05). Taking non-return-to-work status as the reference category, the multinomial logistic regression model showed the adverse factors for return to original post included low educational attainment (college diploma or below), on-site placement service, increased lost workdays and low employment intention (pre-contemplation and contemplation stages); the protective factor was positive evaluation of health transition (HT); for patients transferred to new posts, adverse factors were low employment intention (pre-contemplation stage) and increased lost workdays, while protective factors covered on-site placement service and positive HT evaluation. ConclusionComprehensive vocational rehabilitation can improve the quality of life for injured workers. Better quality of life is positively associated with return-to-work outcomes. HT, education level, job placement mode, lost workdays and employment willingness are independent factors impacting return-to-work outcomes.

Background/Aims: Cholangiocarcinoma (CCA) is a primary malignant neoplasm with an extremely poor prognosis. While combined chemoradiotherapy has been demonstrated to delay CCA progression to a certain extent, the absence of specific molecular biomarkers or targets significantly hinders the diagnosis and treatment of CCA. Methods: Through cross-analysis of proteomics and ADMA modificationomics, we identified DDX1 overexpressed in CCA with elevated R602-ADMA modifications. HPLC-MS/MS identified PRMT1 as the methyltransferase and USP10 as the deubiquitinating enzyme for DDX1. Immunofluorescence and nuclear-cytoplasmic partitioning experiments confirmed DDX1’s nuclear localization. GO and KEGG analyses clarify the biological functions of DDX1 in response to hypoxia. RNA-seq transcriptomics analyzed key pathways influenced by DDX1. A hydrodynamic in situ CCA mouse model was established to validate the chemopreventive effects of the PRMT1-specific inhibitor GSK715 on CCA development. Results: DDX1 promotes CCA progression both in vivo and in vitro and can be inhibited by GSK715. Mechanistically, PRMT1 mediates ADMA modification at position R602 of DDX1. This modification promotes DDX1 nuclear localization by recruiting USP10 to deubiquitinate DDX1, while simultaneously inhibiting PRMT1 degradation. DDX1 promotes the transcription of PRMT1 and USP10 by binding to the mRNA 3’UTR region, establishing a positive feedback regulatory pathway. This mechanism promotes the occurrence and development of CCA and can serve as a target for the inhibitor GSK715 to suppress CCA progression. Conclusions Our study identified DDX1-R602-ADMA modification as a novel ADMA modification in CCA. It further confirmed its pivotal role in CCA progression. Targeting the USP10-PRMT1-DDX1 axis may represent a significant therapeutic approach for CCA.

Objective Using cockroach surveillance data in Nanjing from 2017 to 2024, we have descriptively analyzed population characteristics and changes in insecticide resistance among Blattella germanica, and have established a seasonal Autoregressive Integrated Moving Average (ARIMA) model to predict monthly population densities in Nanjing spanning the year 2025. Methods B. germanica density and infestation rate were monitored using the sticky trap method, and insecticide resistance was assessed using the residual contact method. Our ARIMA model was applied to fit and estimate cockroach density fluctuations over time. Results From 2017 to 2024, B. germanica accounted for 94.90% of all cockroach specimens captured in Nanjing, with an average density of 0.37 cockroaches per trap and an average infestation rate of 5.56%. Significant differences in density and infestation rate were observed among different habitats (P＜0.001). Significant downward annual trends in both density and infestation rate were found (P＜0.05). ARIMA was found to be the optimal model for fitting the density data from 2017 to 2024 (0, 1, 1) × (0, 1, 1)1 2. Conclusions From 2017 to 2024, B. germanica was overwhelmingly the dominant cockroach species in Nanjing, with both its density and infestation rate declining annually. A positive correlation was observed between the amount and proportion of insecticide use and the development of insecticide resistance (P＜0.05). The established model demonstrated good performance in predicting monthly B. germanica densities in Nanjing throughout 2025, providing a valuable reference for future surveillance and control efforts.

Objective To evaluate the safety and efficacy of a new domestic ultra-high frequency bipolar radiofrequency ablation device. Methods Six fresh cadaveric lumbar spine specimens were used as experimental subjects, and a novel domestic ultra-high frequency bipolar radiofrequency ablation device was employed for nucleus pulposus ablation and annulus fibrosus cauterization. Nucleus pulposus ablation: a total of 18 intervertebral discs from L₁ to L₄ were selected and randomly divided into six groups. Radiofrequency electrodes were inserted into the intervertebral discs through the lateral aspect of the intervertebral foramen, and the ablation was performed at power outputs of 50 W, 75 W, and 100 W for 1 min and 2 min, respectively. The ablation of the nucleus pulposus was observed, and the ablation range was recorded. Annulus fibrosus cauterization: a total of 12 intervertebral discs from L₄ to S₁ were divided into three groups based on cauterization duration of 3 s, 10 s, or 15 s. In a water bath maintained at a constant 37 °C, cauterization was performed at power outputs of 20 W, 30 W, and 40 W, respectively. After hard tissue sectioning and hematoxylin and eosin (HE) staining, the depth of cauterization and the carbonization of surrounding soft tissues were observed. Results No obvious vaporization cavity was observed in the nucleus pulposus at a power of 50 W for either 1 or 2 min. The 100 W–2 min group achieved the largest ablation area ([7.471±0.365] mm², P＜0.001). The temperature elevation at all four annulus fibrosus sites remained below 0.5℃ throughout the ablation process. The cauterization depth in the 20 W group was significantly lower than that in both the 30 W and 40 W groups across all time conditions (P＜0.01), whereas no statistically significant difference was observed between the latter two. In 20 W group, the cauterization depth at 3 s was significantly lower than that of the 10 s and 15 s groups (P＜0.01). No significant intra-group differences were found among subgroups with different cauterization durations in the 30 W and 40 W groups. An effective cauterization depth was already achieved at 30 W for 3 s. Conclusions Ex vivo experiments have shown that the new domestic bipolar radiofrequency ablation device possesses excellent ablation efficacy and safety parameters. For nucleus pulposus ablation, it is recommended to use 100 W for 2 min, while for annulus fibrosus cauterization and shaping, 30 W for 3 s is suggested. Its clinical application value remains to be further verified through in vivo studies.

Objective:To investigate the application of the conjugate gradient (CG) algorithm to treatment plan optimization for intensity-modulated brachytherapy (IMBT).Methods:The general Monte Carlo software TOPAS was utilized to simulate the 192Ir source of IMBT, and the unit dose contribution matrix was calculated. An objective function was established using the weighted least squares method and was solved using the CG algorithm to achieve optimized IMBT treatment plans. The optimization was validated using five clinical cervical cancer cases under modulation width 60°. The dose distributions of IMBT treatment plans under 45°, 60°, 90°, 120°, and 180° modulation widths were compared using the Wilcoxon test to determine the optimal IMBT treatment plan for cervical cancer treatment. Results:The CG algorithm successfully optimized IMBT treatment plans under modulation width 60° for five cases within 22.2 s on average. On the premise of sufficient target dose coverage, the average D2 cm 3 values of the bladder and rectum in IMBT treatment plans were 3.66 and 1.97 Gy, respectively, representing reductions of 0.54 and 0.69 Gy compared to traditional brachytherapy plans. For the five modulation widths, the D90% values of all IMBT treatment plans reached 6 Gy, without statistically significant differences ( P > 0.05). The average D2 cm 3 values of the bladder in IMBT treatment plans were significantly lower than those in the traditional brachytherapy plans( P<0.05), with modulation width 60° associated with the greatest reduction of 0.61 Gy. In contrast, the average D2 cm 3 values of the rectum under 45°, 60°, and 90° modulation widths decreased by 0.63, 0.54, and 0.45 Gy, respectively, compared to traditional plans, with statistically significant differences( P<0.05). Conclusions:The CG method enables rapid achievement of optimized IMBT treatment plans that meet clinical requirements, and modulation width 60° contributes to valid dosimetric optimization. This study can serve as a guide for the clinical implementation of IMBT.

There are no reports on the application of perirenal fat covering technique in lingual mucosal graft ureteroplasty（LMGU），and its safety and effectiveness need to be observed. This study retrospectively analyzed clinical data of 7 patients who underwent lingual mucosa ureteroplasty with intraoperative perirenal fat covering technique. The median stricture length was 5.5（range 4.0 to 6.0）cm，operative duration was 170（range 120 to 230）min，estimated blood loss was 92（range 15 to 110）ml. No conversions to open surgery occurred. During a median follow-up of 46（range 8 to 86）months，all procedures achieved clinical success. The application of perirenal fat covering technique in LMGU is safe and effective.

Three throat swab samples from infants and young children in Hubei Province were identified as positive for enteroviruses. All subjects were one month old, and the onset of symptoms occurred in June; these cases were sporadic and exhibited no clear epidemiological associations. The results of VP1 gene amplification analysis indicated that all three infant cases were attributed to Echovirus 30 (ECHO30). The ECHO30 strain isolated from the three samples was classified as Cluster Ⅲ within the H gene subtype. Whole genome amplification analysis revealed that the ECHO30 strain from Hubei exhibited the highest homology with ECHO30/MW586892/Ashburton/17WQ2027G/USA/2007-08-20 from GenBank, demonstrating nucleotide and amino acid homologies of 97.6% and 99.3%, respectively. Recombination analysis indicated the presence of recombination events in the non-structural protein region of the ECHO30 Hubei strain, with recombinant fragments potentially originating from ECHO30/KY888274/14-397/Germany/2013 and ECHO18 strains Echo18/MN815811/BJ2018-S6363/Beijing/2018. This study provides a comprehensive analysis of the genetic evolution of the ECHO30 strain prevalent in Hubei Province, contributing essential data for the prevention of ECHO30 infections.

Objective:To investigate the clinical and radiological differences in treating single-level cervical spondylosis using the Zero-profile interbody fusion cage (Zero-PVA) versus the titanium plate interbody fusion cage in anterior cervical discectomy and fusion (ACDF) and to analyze the correlation between clinical outcomes and radiological parameters.Methods:this retrospective study collected data from patients with cervical spondylosis who underwent single-level ACDF surgery at the First Affiliated Hospital of Kunming Medical University between January 2019 and June 2022. A total of 70 patients (32 males and 38 females) with an average age of 51.34 ± 8.62 years (range: 29 to 77 years) were included. Based on the type of interbody fusion device used, patients were divided into two groups: the cage-plate construct (CP) group (35 patients; average age: 51.51 ± 10.02 years, range: 29 to 77 years) and the zero-profile interbody fusion device with variable angle (ZP) group (35 patients; average age: 51.17±7.11 years, range: 38 to 68 years). Preoperative, one-week postoperative, and final follow-up (≥6 months postoperative) data were collected for visual analogue scale (VAS) scores, neck disability index (NDI) scores, and Japanese Orthopaedic Association (JOA) scores. Radiological parameters assessed included surgical segment intervertebral disc height, cervical lordosis angle, surgical segment Cobb angle, T 1 slope (T 1S), and C 2-C 7 sagittal vertical axis (C 2-C 7 SVA). Additional evaluations included Bazaz dysphagia ratings at one week and final follow-up, Odom surgical outcome ratings at final follow-up, fusion grades, adjacent vertebral ectopic ossification grades, and adjacent segment degeneration. Patients were further classified into a symptom relief group and an incomplete symptom relief group based on Odom ratings. Logistic regression analysis was performed to examine the correlation between radiological parameters and postoperative outcomes. Statistical methods such as ROC curves, Youden index, product index, and Euclidean index were used to determine optimal cut-off values for radiological parameters affecting postoperative outcomes. Results:There were no statistically significant differences between the two groups in terms of gender, age, follow-up duration, surgical segment, or classification ( P>0.05), confirming comparability. At both one-week post-operation and final follow-up, VAS, NDI, and JOA scores showed no significant differences between the groups ( P>0.05). However, the incidence of dysphagia in the CP group was 49% at one week post-operation and 20% at final follow-up, significantly higher than that in the ZP group (14% at one week and 0 at final follow-up; P<0.05). The intervertebral space height in the CP group was 9.16±0.84 mm at one week post-operation and 8.19±1.11 mm at final follow-up, which was significantly higher than in the ZP group (8.22±1.23 mm at one week and 7.57±1.14 mm at final follow-up; P<0.05). The surgical segment Cobb angle in the CP group at final follow-up (7.34°±4.21°) was significantly greater than in the ZP group (4.63°±4.32°; t=2.661, P=0.010). Regarding heterotopic ossification (HO) of the superior vertebral body, in the CP group, 27 cases were grade 0, 7 cases were grade 1, and 1 case was grade 2. In the ZP group, 34 cases were grade 0 and 1 case was grade 1, with a statistically significant difference between the groups (χ 2=6.128, P=0.028). Binary logistic regression analysis revealed that a reduction in intervertebral space height of ≥0.63 mm at one week post-operation and final follow-up ( OR=2.913, P=0.021) and a heterotopic ossification grade of ≥1 ( OR=5.178, P=0.042) were correlated with incomplete symptom relief after single-level ACDF surgery. Conclusions:Both Zero-PVA and titanium plate interbody fusion devices demonstrated favorable clinical outcomes in single-level ACDF surgery. However, a reduction in intervertebral space height and heterotopic ossification of the superior vertebral body may be risk factors for incomplete symptom relief following single-level ACDF.
