The Consolidated Standards of Reporting Trials (CONSORT) statement aims to enhance the quality of reporting for randomized controlled trial (RCT) by providing a minimum item checklist. It was first published in 1996, and updated in 2001 and 2010, respectively. The latest version was released in April 2025, continuously reflecting new evidence, methodological advancements, and user feedback. CONSORT 2025 includes 30 essential checklist items and a template for a participant flow diagram. The main changes to the checklist include the addition of 7 items, revision of 3 items, and deletion of 1 item, as well as the integration of multiple key extensions. This article provides a comprehensive interpretation of the statement, aiming to help clinical trial staff, journal editors, and reviewers fully understand the essence of CONSORT 2025, correctly apply it in writing RCT reports and evaluating RCT quality, and provide guidance for conducting high-level RCT research in China.

"Toxicity Testing in the 21st Century—A Vision and Strategy"proposed by the National Research Council of US has brought innovative directives and objectives for toxicity evaluation and risk assessment,pushing forward the next generation of toxicity testing and risk assessment.In this initiative,the concept of adverse outcome pathways(AOPs)has emerged as a prominent methodology,capturing the attention of toxicologists and researchers due to its promising applications in recent years.The quantitative AOP(qAOP)is an extension of the adverse outcome pathway,which is built upon the foundational qualitative adverse outcome pathway model and leverages mathematical frame-works to depict dose-response and/or response-response relationships.This article reviews the princi-ples and advancement surrounding qAOP,introduceds two prevalent methodologies for constructing qAOP,Bayesian network models and regression models,and demonstrates diverse applications of qAOP.Actual cases are used to underscore the transformative role of qAOP in contemporary toxicology and risk assessment practices.

Objective:To investigate the application effect of scenario simulation teaching combined with progressive cases in pediatric nursing teaching.Methods:A total of 60 nursing students who studied in Department of Pediatric Internal Medicine in Yan'an University Affiliated Hospital from July 2022 to November 2023 were selected as subjects, and according to the order of admission, they were divided into control group and observation group, with 30 students in each group. The students in the control group received traditional teaching, while those in the observation group received scenario simulation teaching combined with progressive case teaching. The two groups were assessed in terms of learning outcomes and degree of satisfaction with teaching. SPSS 22.0 was used to perform the chi-square test and the t-test. Results:There was a significant difference in theoretical assessment score between the control group and the observation group [(83.56±5.29) vs. (87.02±6.08), t=7.56, P=0.006]. Compared with the control group, the observation group had significantly higher scores of nursing operation proficiency, problem-solving ability, communication and coordination ability, emergency response ability, humanistic care, psychological care, and nursing service attitude ( P<0.001). Compared with the control group, the observation group also had a significantly higher total score and significantly higher scores of teaching contents, teaching arrangement, teaching effect, and overall learning gain ( P<0.001). Conclusions:The application of scenario simulation teaching combined with progressive cases in pediatric nursing teaching can effectively improve teaching quality and degree of satisfaction, enhance knowledge reserve and attitude of nursing interns, and promote the development of pediatric nursing.

Objective: To understand and analyze the epidemiological characteristics of dental caries in children and its effects on jaw function, so as to prevent occurrence of abnormality of jaw function. Methods: In October 2020, 860 cases of children from 5 kindergartens and 3 primary schools in Beijing were selected by adopting the convenience sampling method. All of them received oral examination, and the questionnaire according to the fourth national oral health epidemiological survey standard, including demographic information, eating habits, oral hygiene habits, oral health care,etc. The epidemiological characteristics of dental caries in children and its effects on jaw function were analyzed. Results: A total of 190 children had dental caries, with a dental caries incidence rate of 22.09%. Dental caries in children s deciduous teeth or permanent teeth was related to age, residence, parents education level,whethe to eat before going to bed, whether eating sweet food, tooth brushing age, daily brushing frequency, whether parents have assisted tooth brushing, whether regular oral examination, whether parents have received oral health guidance( χ 2= 5.04 ,4.70，75.37，7.91，12.03，9.30，7.64，255.47，253.27，11.38, P <0.05). Compared with the noncaries group[(81.52±3.16， 80.54± 1.52，1.92±0.25，31.52±1.62，33.63±3.41，50.72±1.68)°], the sella nasion A point(SNA), sella nasion B point(SNB),A point nasion B point(ANB),frankfot horizontal mandibular plane angle(FH MP),skull nasion mandibular plane angle(SN MP),anteriors relationship palataplane mandibular(Ptm ANS) decreased in the dental caries group[(78.62±2.11，79.35±1.02，1.68±0.32，30.69±0.45，32.15±3.02，48.62±1.21)°](t=78.62,79.35,10.94, 30.69, 32.15, 48.62, P<0.05). Conclusion The prevalence of caries in children was high and jaw structure abnormalities and dysfunction. It is suggested that caries prevention and control work should be carried out early to strengthen the prevention and control of oral disease education work.

Objective:To explore the relation among self-esteem, psychological flexibility and mental health in medical students, and to provide scientific reference for mental health education for medical students.Methods:A total of 788 medical students selected from a medical university in Chongqing City were investigated with the symptom checklist 90 (SCL-90), self-esteem scale (SES), acceptance and action questionnaire-Ⅱ (AAQ-Ⅱ), and cognitive fusion questionnaire-fusion (CFQ-F). SPSS 22.0 software was used for statistical analysis. T test, ANOVA, correlation analysis and tests for mediation effects were conducted. Results:There were significant differences in self-esteem and mental health level among medical students in gender and different grades ( t=-2.55, P<0.05; F=6.53, P<0.05). Mental health, self-esteem and psychological flexibility of medical students were correlated in pairs ( r=-0.528-0.694, P<0.01). Psychological flexibility played a partial mediation role between self-esteem and mental health of medical students, and the mediating effect accounted for 60.03% of the total effect. Conclusion:Self-esteem can directly predict the mental health of medical students, and can also indirectly affect mental health through psychological flexibility. Medical universities should carry out psychological education and promotion work with pertinence.

Objective:To investigate the factors related to gastroesophageal reflux disease (GERD) in children.Methods:Clinical data of 370 children who underwent 24h multi-channel impedance-pH monitoring (24h MII-pH) in Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2015 to December 2020 were enrolled in the study. The children were divided into GERD group ( n=202)and non-GERD group ( n=168) according to results of 24h MII-pH. The relationship of sex, age, body mass index (BMI), disease course, peripheral blood eosinophils count, IgE, Helicobacter pylori (Hp) infection, hiatus hernia of patients with GERD was analyzed by univariate and multivariate logistic regression analysis. Results:In GERD group 124 were males and 78 were females with a mean age of (6.4±4.1) years (2 months to 16.75 years), and in non-GERD group 82 were males and 86 were females with a mean age of (8.0±3.5) years (10 months to 15.17 years). Univariate logistic regression analysis showed that sex( OR=0.600,95% CI:0.396-0.908, P=0.016), age ( OR=0.537,95% CI:0.412-0.699, P<0.001)and hiatus hernia( OR=7.433,95% CI:2.567-21.520, P<0.001)were significantly associated with GERD of the children. Multivariate analysis showed that hiatus hernia ( OR=4.023,95% CI:1.298-12.470, P=0.016) was the independent risk factor, while male gender ( OR=0.567,95% CI:0.367-0.874, P=0.010) and younger age ( OR=0.613, 95%CI:0.459-0.819, P=0.001 ) were related factors of gastroesophageal reflux disease in children. Conclusion:Sex, age, and hiatal hernia are factors related to GERD in children.
