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.

Background: This study was performed to characterize the incidence, costs, and risk factors associated with renal and cardiovascular adverse outcomes following primary percutaneous coronary intervention (pPCI) in patients with ST-elevation myocardial infarction (STEMI). Methods: Patients with STEMI who underwent pPCI using iso-osmolar contrast were enrolled at 39 centers. The incidence of acute kidney injury (AKI) and major adverse renal and cardiovascular events (MARCE) was analyzed, as well as inpatient costs. Logistic regression analysis was performed to identify risk factors. Results: Among 2,293 patients, the incidence of AKI and MARCE within 72 hours post-pPCI was 4.14% (n = 95) and 4.40% (n = 101), respectively. AKI and/or MARCE were associated with systolic blood pressure (AKI: odds ratio [OR], 1.009; 95% confidence interval [CI], 1.000–1.018), hypertension (AKI: OR, 1.815; 95% CI, 1.133–2.906; MARCE: OR, 1.760;95% CI, 1.118–2.769), anterior wall infarction (AKI: OR, 1.895; 95% CI, 1.196–3.004; MARCE:OR, 1.939; 95% CI, 1.240–3.032), Killip class (AKI: OR, 1.465; 95% CI, 1.117–1.922; MARCE:OR, 1.467; 95% CI, 1.131–1.903), and serum creatinine (SCr; MARCE: OR, 1.006; 95% CI, 1.000–1.012). Hospitalization costs for patients with STEMI who developed AKI or MARCE were significantly higher than for those without AKI (9,595 ± 5,795 vs. 8,279 ± 3,872 USD, P = 0.003) or without MARCE (9,890 ± 5,616 vs. 8,255 ± 3,859 USD, P < 0.001). Conclusions In patients with STEMI undergoing pPCI with iso-osmolar contrast, the incidence of AKI and MARCE was associated with higher hospitalization costs. Systolic blood pressure, hypertension, anterior wall infarction, Killip class, and SCr were identified as risk factors for these outcomes.

Objective To heterologously express and purify the small ubiquitin-like modifier(SUMO)tag fused organo-phosphorus hydrolase mutant H257Y/L303T(YT),namely SUMO-YT,and evaluate its hydrolytic capacity against ethyl paraoxon and soman.Methods The SUMO tag encoding gene was constructed at the N-terminus of the YT encoding gene with a linker sequence via enzyme digestion and ligation before SUMO-YT was expressed in Escherichia coli.SUMO-YT and YT were purified through ammonium sulfate precipitation and affinity chromatography to obtain high-purity target proteins.The activity and kinetic parameters of the recombinant enzymes were examined using ethyl paraoxon and soman as substrates.Results The system for expression and purification of recombinant enzymes was established,yielding SUMO-YT and YT,and the former exhibited more significantly enhanced hydrolytic efficiency than the latter,with catalytic rates 11-fold higher for paraoxon and 4.4-fold higher for soman.At 37 ℃ and pH 7.2,SUMO-YT reduced the inhibition rate of acetylcholinesterase(AChE)by soman from 100％to 45.7％within 3 minutes,whereas YT reduced it to no more than 80％.Conclusion The high-activity recombinant SUMO-YT is prepared.SUMO tag fusion can significantly enhance the hydrolytic capacity of YT against ethyl paraoxon and soman.

Objective To provide a comprehensive review of the modeling method of the empty bottle stimulation(EBS)anxiety model,including commonly used experimental animal strains and genders,animal grouping,modeling procedures,modeling duration,primary behavioral evaluation method,and the underlying pathological mechanisms.This aims to offer a reference for the application of the EBS anxiety model in anxiety disorder research.Methods Searches were conducted in databases such as CNKI and PubMed to collect all literature related to the EBS anxiety model,which were then systematically summarized and organized.Results(1)Male adult SD or Wistar rats are predominantly used as experimental animals;(2)The optimal modeling period is 2 weeks;(3)Behavioral evaluations primarily utilize the open field test,elevated plus maze test,and light-dark box test;(4)Pathological mechanisms involve abnormal neurotransmitter metabolism in brain regions such as the hippocampus,prefrontal cortex,and amygdala.Conclusions The EBS anxiety model exhibits an anxiety-like behavioral phenotype and associated neurobiological mechanisms,validating its utility as an animal model for the study of anxiety disorders.However,further exploration and refinement are required for its standardized construction protocol and the understanding of its mechanistic underpinnings.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Clinical management of atopic dermatitis (AD) is challenged by its susceptibility to recurrence, side effects, and high costs. We found that Portulaca oleracea L.-derived nanovesicles (PDNV) exert anti-inflammatory effects by modulating macrophage M1/M2 polarization. These effects were achieved through pathways including inhibition of nuclear factor-κB (NF-κB) and stimulator of interferon genes (STING) protein expression in diseased tissues, demonstrating their potential to ameliorate AD symptoms. To increase the transdermal permeation of PDNV, dissolvable microneedles composed primarily of hyaluronic acid (HA) were developed as an adjunctive means of delivery. Meanwhile, polysaccharides of Portulaca oleracea L., which were synergistic with PDNV, were used as microneedle constituent materials to enhance the mechanical properties and physical stability of HA. This new means of delivery significantly improves the treatment of AD and also provides new options for the efficient utilization of plant extracellular vesicles and the treatment of AD. In addition, transcriptomic analysis of PDNV showed that the mRNAs of Portulaca oleracea L. are closest to those of ferns, which may shed light on related evolutionary and plant species identification studies.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Salmonella,an important foodborne pathogen,is responsible for numerous diseases in both humans and animals.We conducted a genome-wide analysis of Salmonella isolates from diarrheal and foodborne infection cases in Gansu Province between 2021 and 2023.A total of 163 Salmonella strains were collected and subjected to biochemical identification,followed by serological typing,whole-genome sequencing,and bioinformatics characterization.The results revealed 27 distinct serotypes,among which Sal-monella typhimurium variant(S.4,[5],12∶1∶-),Salmonella enteritidis,and Salmonella enterica London were predominant.Notably,the serotype distribution exhibited significant variation across sample sources.Multilocus sequence typing(MLST)classified the iso-lates into 27 sequence types(STs),among which ST34,ST11,ST155,and ST19 had the highest prevalence.The MLST profiles dem-onstrated strong concordance with serological classifications.For Salmonella,we detected a total of 17 673 virulence genes in 374 cat-egories,carrying multiple virulence islands.Some strains carried virulence plasmid genes,among which 45 strains of Salmonella enter-itidis had higher types and numbers of virulence factors detected than other serotypes of Salmonella.Antimicrobial resistance profiling identified 69 resistance genes conferring resistance to 13 classes of antimicrobial agents,and multidrug resistance patterns were preva-lent among isolates.Plasmid characterization revealed 35 plasmid types,some containing antimicrobial resistance determinants.Addi-tionally,three disinfectant resistance genes were identified.This study highlights the extensive diversity of Salmonella serotypes and STs in Gansu Province and the complex repertoire of virulence and resistance genes.The emergence of disinfectant resistance genes un-derscores challenges in conventional disinfection protocols.These findings provide critical insights for refining Salmonella surveillance and control strategies in public health and food safety contexts.

Objective:To explore the clinical efficacy of modified Yiqi Huayu pelvic inflammation decoction combined with retention enema of traditional Chinese medicine (TCM) and moxibustion at Shenque acupoint in the treatment of patients with chronic pelvic inflammatory disease (CPID).Methods:A total of 120 CPID patients admitted to the Qian′an City Traditional Chinese Medicine Hospital from January 2023 to June 2024 were prospectively enrolled and randomly divided into the control group (60 cases, treated with modified Yiqi Huayu pelvic inflammation decoction) and the observation group (60 cases, treated with modified Yiqi Huayu pelvic inflammation decoction plus TCM retention enema and moxibustion at Shenque acupoint) using a random number table. Each course of treatment was 3 weeks, with drug withdrawal for 1 week during menstruation, and continuous treatment for 2 courses. The clinical efficacy of the two groups was observed. The TCM symptom scores, blood microcirculation indicators [whole blood low shear viscosity (LBV), whole blood high shear viscosity (HBV), platelet aggregation rate (PAR), hematocrit (HCT)], and serum inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), high mobility group box 1 (HMGB1), granulocyte-macrophage colony-stimulating factor (GM-CSF)] before and after treatment were compared. The patients were followed up for 3 months after treatment to compare the incidence of adverse reactions and recurrence between the two groups.Results:The total clinical effective rate of the observation group (95.00%, 57/60) was higher than that of the control group (83.33%, 50/60) ( P<0.05). After treatment, the individual scores of main and secondary symptoms and the total score of TCM syndrome in the observation group were lower than those in the control group (all P<0.05). After treatment, the levels of LBV, HBV, PAR, HCT, TNF-α, IL-2, HMGB1, and GM-CSF in the observation group were lower than those in the control group (all P<0.05). There was no statistically significant difference in the total incidence of adverse reactions between the two groups ( P>0.05). During the 3-month follow-up after treatment, the recurrence rate of the observation group was 3.33%(2/60), which was lower than 15.00%(9/60) of the control group ( P<0.05). Conclusions:Modified Yiqi Huayu pelvic inflammation decoction combined with TCM retention enema and moxibustion at Shenque acupoint has a definite efficacy in the treatment of CPID. It can effectively relieve clinical symptoms, improve blood microcirculation and inflammatory factor levels of patients, with a low short-term recurrence rate and no significant increase in the incidence of adverse reactions.
