Objective To investigate the expression levels of serum miR-186-5p and miR-942-5p in patients with glioma and their clinical significance.Methods A total of 98 patients with glioma who were treated in this hospital from October 2019 to December 2021 were selected as the monitored group,and 101 healthy indi-viduals who underwent physical examinations a the same time were selected as the control group.Quantitative fluorescent PCR(qPCR)method was applied to detect the expression levels of miR-186-5p and miR-942-5p in serum,and multivariate COX regression was applied to analyze the prognostic factors of glioma patients.Re-ceiver operating characteristic(ROC)curve and area under curve(AUC)were used to analyze the diagnostic value of serum miR-186-5p and miR-942-5p in glioma.Kaplan-Meier survival curve was used to analyze the re-lationship between serum miR-186-5p and miR-942-5p expression and prognosis of patients.Results The ex-pression level of serum miR-186-5p in monitored group was lower than that in the control group(P＜0.05),and the expression level of miR-942-5p was higher than that in the control group(P＜0.05).The AUC of ser-um miR-186-5p and miR-942-5p in the diagnosis of glioma alone and in combination were 0.735,0.809 and 0.895,respectively.There were significant differences in the proportion of low miR-186-5p expression and high miR-942-5p expression in serum of patients with different preoperative Karnofsky performance status(KPS)scores,World Health Organization(WHO)grades and local infiltration(P＜0.05).The 2-year surviv-al rate of patients with high expression of miR-186-5p was higher than that of patients with low expression of miR-186-5p(x2=6.455,P=0.011).The 2-year survival rate of patients with high miR-942-5p expression was lower than that of patients with low miR-942-5p expression(x2=9.858,P=0.002).miR-186-5p was a protective factor for mortality in glioma patients(P＜0.05),while miR-942-5p was a risk factor(P＜0.05).Conclusion Serum miR-186-5p expression level decreases and miR-942-5p expression level increases in glioma patients,both of which have certain diagnostic value for the occurrence of glioma.

In recent years, the spread of clubroot disease caused by Plasmodiophora brassicae infection has seriously affected the yield and quality of Brassica juncea (L.) Czern.. The cascade of mitogen-activated protein kinases (MAPKs), a highly conserved signaling pathway, plays an important role in plant responses to both biotic and abiotic stress conditions. To mine the MAPK genes related to clubroot disease resistance in B. juncea, we conducted a genome-wide analysis on this vegetable, and we analyzed the phylogenetic evolution and gene structure of the MAPK gene family in mustard. The 66 BjuMAPK genes identified by screening the whole genome sequence of B. juncea were unevenly distributed on 17 chromosomes. At the genomic scale, tandem repeats led to an increase in the number of MAPK genes in B. juncea. It was found that members of the same subfamily had similar gene structures, and there were great differences among different subfamilies. These predicted cis-acting elements were related to plant hormones, stress resistance, and plant growth and development. The expression of BjuMAPK02, BjuMAPK15, BjuMAPK17, and BjuMAPK19 were down-regulated or up-regulated in response to P. brassicae infection. The above results lay a theoretical foundation for further studying the functions of BjuMAPK genes in B. juncea in response to the biotic stress caused by clubroot disease.

Objective To evaluate the reliability of Vitek 2 AST-N335 card for determining the susceptibility of Acinetobacter bauman-nii(AB)to cefoperazone/sulbactam.Methods A total of 318 non-repeated clinical isolates of AB collected in 2023 were tested for antimicrobial susceptibility to cefoperazone/sulbactam using broth microdilution(BMD),the AST-N335 card,and the Kirby-Bauer(K-B)disk diffusion method.Using BMD as the reference method,the reliability of AST-N335 card was assessed,and the accuracy of K-B disk diffusion method as the confirmatory test was validated.Results Compared with BMD,the susceptibility testing of 318 AB strains to cefoperazone/sulbactam using the AST-N335 card showed categorical agreement(CA)of 87.8％(279/318),very major er-ror(VME)of 6.0％(19/318),major error(ME)of 0％(0/318),and minor error(mE)of 1.9％(6/318),which fall outside of the acceptable error range.In contrast,the K-B method achieved CA of 99.4％(316/318),VME of 0％,ME of 0.3％(1/318),and mE of 0.3％(1/318),all within acceptable limits.Of these,the errors with AST-N335 card occurred within the minimum inhibitory concentration(MIC)range of 8-32 μg/mL.Using BMD as the reference method,further analysis was performed on the 171 AB strains with AST-N335 card MIC values of 8-32 μg/mL for cefoperazone/sulbactam.It was revealed that at MIC of 32 μg/mL,the CA was 0％;at MIC of 16 μg/mL,CA was 5.3％(1/19)and VME rate was 84.2％(16/19),both of which substantially exceeded accepta-ble error ranges.At MIC of 8 μg/mL,the CA was 94.9％(131/138)and VME was 2.2％(3/138),both approaching the acceptable ranges.Conclusion The results obtained with Vitek 2 AST-N335 card in determining for cefoperazone/sulbactam are unreliable when the MIC values fall within the range of 8-32 μg/mL,which leads to an underestimation of the resistance rate to cefoperazone/sulbac-tam.This issue requires urgent attention in both laboratories and clinical practice.The K-B disk diffusion method could serve as a sup-plementary verification approach in routine laboratories.

Objective:To understand the current status of family resilience in children with autism and explore its influencing factors, providing a basis for developing intervention measures to improve family resilience in these families.Methods:Convenience sampling was used to select children with autism and their caregivers who underwent rehabilitation training at the Department of Child Developmental Behavior, Third Affiliated Hospital of Zhengzhou University from March to September 2023. A cross-sectional survey was conducted using a general information questionnaire, the Chinese version of the Family Resilience Assessment Scale, the Chinese version of the Parenting Burnout Scale, and the Caregiver Stress Scale.Results:A total of 280 questionnaires were distributed, and 271 valid questionnaires were collected. Among the 271 children with autism, 210 were male and 61 were female, with the majority aged 3-5 years old (169 cases). Among the 271 caregivers, 21 were male and 250 were female, with the majority aged 30-39 years old (149 cases). The total score of the Chinese version of the Family Resilience Assessment Scale was (70.59 ± 14.08) points, with scores of (49.96 ± 10.23) points for family communication and problem-solving, (7.13 ± 1.62) points for social resource utilization, and (13.52 ± 3.31) points for maintaining a positive attitude. Multiple linear regression analysis showed that the child′s age, disease duration, reimbursement method, parenting burnout, and caregiver stress were influencing factors of family resilience in children with autism ( t values were -10.40-3.48, all P<0.05). Conclusions:The level of family resilience in children with autism needs improvement. Higher levels of parenting burnout and caregiver stress are associated with lower levels of family resilience. Future interventions should be developed based on these influencing factors to promote the physical and mental health of children with autism and their caregivers.

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.

Objective:To understand the epidemiological characteristics and changing trends of injury-related deaths in local residents in Qingdao from 2014 to 2023, and provide evidence for development of injury prevention and control measures.Methods:The incidence data on fatal injury in residents of Qingdao from 2014 to 2023 were used to describe the epidemiological characteristics of fatal injury by using fatal injury rate, standardized fatal injury rate, proportion, and death order. The average annual percentage change (AAPC) was used to describe the annual change in fatal injury rates, and the trend of fatal injury was analyzed.Results:From 2014 to 2023, a total of 23 533 residents died of injury in Qingdao, with a crude fatal injury rate of 28.74/100 000 and a standardized fatal injury rate of 27.64/100 000. The total fatal injury rate showed a downward trend (AAPC: -5.06%, P<0.05). The top three causes of fatal injury in the residents were road traffic accident (40.85%), suicide (15.80%), and accidental falls (12.92%). In terms of gender specific fatal injury cause, the top one in both men and women was road traffic accident injury. In terms of age specific fatal injury cause, the top one was road traffic accident in the all age groups, except age group 5-14 years with top cause of drowning. From 2014 to 2023, the fatal injury rates of road traffic accident, suicide, and accidental poisoning in the top five fatal injury causes showed a downward trend year by year (AAPC:-7.42%, -6.54%, -13.95%, P<0.05). Conclusions:The fatal injury rate showed a downward trend in the residents in Qingdao from 2014 to 2023. It is necessary to strengthen the prevention and control of road traffic accident injury, suicide, falls in the elderly, and drowning in adolescents.

Objective:To evaluate the effects of chlorinated organophosphate flame retardants (Cl-OPFRs) via respiratory and digestive tract exposure on multiple organs in mice.Methods:A short-term repeated exposure model of tris(2-chloroethyl) phosphate (TCEP), tris(1-chloro-2-propyl) phosphate (TCIPP) and tris(1, 3-dichloro-2-propyl) phosphate (TDCIPP) in mice was established through intratracheal instillation and oral gavage administration. The exposure doses were 0.7, 1 and 2 mg·kg -1·day -1, respectively, with continuous administration for 14 days. The organs of the heart, liver, spleen, lung, kidney, stomach, large intestine, small intestine, bladder and testis were collected and weighed to calculate the organ coefficients. The pathological and histological changes were observed by hematoxylin-eosin staining to quantitatively assess the effects of the three Cl-OPFRs on the various organs by using the pathology score. Results:Analysis of organ coefficients in tracheal drip-treated mice showed that the organ coefficients in the testes of the TCEP, TCIPP and TDCIPP groups were lower than those in the control group ( PTCEP-testis=0.045, PTCIPP-testis=0.012 and PTDCIPP-testis<0.001). The organ coefficients were lower in the lungs and small intestines of the TCEP group ( PTCEP-lung=0.006, PTCEP-small intestine=0.042). The organ coefficients for the stomach and large intestine were higher in the TDCIPP group ( PTDCIPP-stomach=0.014, PTDCIPP-large intestine=0.049). Analyses of gavage-contaminated mice showed that the organ coefficients for liver, stomach and small intestine in the TCEP and TDCIPP groups were higher than those in the control group ( PTCEP-liver=0.007, PTCEP-stomach=0.003, PTCEP-small intestine<0.001, PTDCIPP-liver=0.001, PTDCIPP-stomach=0.004, and PTDCIPP-small intestine<0.001). Histopathological analyses of the organs of tracheal drip dyed mice showed significant pathological damage in the lung tissue of the TCIPP group, mainly in the form of thickening of the interstitium, infiltration of inflammatory cells and alveolar collapse. The results of the analysis of gavage poisoned mice showed that TCIPP exposure could lead to blurring of the red and white medullary boundaries of spleen tissues, destruction of white medullary structures, etc., and induce small intestinal cryptitis. TDCIPP induced significant pathological damage to the liver tissues of mice, which mainly included cytoplasmic washout, infiltration of inflammatory cells, acute inflammation, and other injurious effects. Significant pathological damage to the intestinal tissues of mice was also observed. Conclusions:This study demonstrates that the toxic effects of Cl-OPFRs are significantly associated with exposure routes and compound specificity. Respiratory exposure predominantly induces TCIPP-mediated pulmonary injury, while digestive exposure causes TDCIPP-driven hepatointestinal toxicity. These findings provide preliminary evidence for the toxicity screening of Cl-OPFRs.

Objective:In order to effectively educate students on tooth defect diseases and restoration techniques, the teaching and research team at the School of Stomatology of Qingdao University developed an integrated course operative dentistry. This course is specifically designed to align with the undergraduate curriculum reform requirements of "Three Early, Two Multiple and One Integration".Methods:The teaching practice of operative dentistry was conducted with the stomatology undergraduates of grade 2020 and 2021. The course group redesigned the curriculum by reorganizing teaching content, rebuilding teaching resources, reconstructing teaching mode, and reshaping the evaluation system. Evaluation of the curriculum design included test scores, satisfaction questionnaires, and teacher self-evaluation. Statistical analysis was performed using SPSS 27.0 software, including independent sample t-tests for numerical variables and Fisher's exact test or Wilcoxon rank sum test for categorical variables. Results:Through the integrated course learning, 92.68% (38/41) of the students of grade 2020 and 97.44% (38/39) of the students of grade 2021 can basically or completely master various dental defect repair schemes and understand the importance of preserving natural tooth. 82.93% (34/41) of the students of grade 2020 and 100.00% (39/39) of the students of grade 2021 could basically or completely master the key points of various dental defect restorations.Conclusions:Through the practice of teaching, it has been confirmed that the integrated course of operative dentistry is beneficial to students' mastering the knowledge and skills of dental defect diseases and their restoration in a more comprehensive way, and is conducive to the cultivation of clinical thinking, hands-on ability and the patient-centered, comprehensive problem-solving thinking, which is in line with the guidance on the innovation and development of medical education.
