BackgroundSuicide among adolescents has become a serious public health issue， with suicidal ideation serving as a necessary precursor to suicide attempts and death. Previous research suggests that campus exclusion， depression， and psychological resilience are closely associated with the development of suicidal ideation in individuals. However， there is a lack of longitudinal research to deeply explore the relationship between each influencing factor and suicidal ideation. ObjectiveTo explore the impact of campus exclusion on suicidal ideation among adolescents， as well as the mediating role of depression and the moderating role of resilience， so as to provide references for formulating strategies for preventing and intervening in adolescent suicide. MethodsAUsing a longitudinal research design， in November 2023， 1 226 students from 21 classes （4 classes per grade in junior high school and 3 classes per grade in senior high school） from a junior high school and a senior high school in a certain area of Shandong Province were selected as the research subjects. The Ostracism Experience Scale for Adolescents （OES-A）， the Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， and the Resilience Scale for Chinese Adolescents （RSCA） were used for assessment. The PHQ-9 suicide ideation item was evaluated again three months after the baseline survey （the two suicide ideation evaluations were respectively denoted as T1 and T2 respectively. Spearman correlation analysis was used to examine the relationships among scale scores. Model 4 and model 59 in the SPSS macro program Process 4.2 were used to test the mediating effect of depression between school exclusion and suicide ideation， as well as the moderating effect of psychological resilience on the three paths. ResultsCorrelation analysis showed that OES-A score was positively correlated with PHQ-9 score and suicidal ideation item score （T2）， and PHQ-9 score was also positively correlated with suicidal ideation item score （T2） （r=0.361， 0.292， 0.508， P<0.01）. RSCA score was negatively correlated with OES-A， PHQ-9， and suicidal ideation （T2） scores （r=-0.500， -0.676， -0.459， P<0.01）. Campus exclusion positively predicted suicidal ideation （T2） and depression （β=0.081， 0.281， P<0.01）， while depression positively predicted suicidal ideation （T2） （β=0.108， P<0.01）. The mediation analysis revealed an effect size of 0.030 （95% CI： 0.019~0.043， P<0.01）， accounting for 37.35% of the total effect. Psychological resilience moderated the relationships between campus exclusion and depression， campus exclusion and suicidal ideation （T2）， and depression and suicidal ideation （T2） （β=-0.059， -0.049， -0.062， P<0.01）. ConclusionA moderated mediation model exists among campus exclusion， depression， resilience， and adolescent's suicidal ideation. Psychological resilience moderates the associations between campus exclusion， depression and suicidal ideation across all three paths. ［Funded by Beijing Municipal Health Commission Clinical Research Excellence Program， （number， BRWEP2024W072130101）；Beijing Municipal Hospital Management Center Summit Program， （number， DFL20221701）］

[Purpose]To analyze the trend of incidence rates of gallbladder cancer in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The incidence data of gallbladder cancer from 1972 to 2021 were collected from the Qidong Tumour Registry database,the crude incidence rate(CR),age-standardized rate by Chinese standard population(ASRC),age-standardized rate by world standard population(ASRW)of gallbladder cancer were calculated.Trend analysis was per-formed using Joinpoint 4.9.1.0 software to calculate the average annual percentage change(AAPC)of gallbladder cancer incidence rates,and time trend analysis was performed on the overall inci-dence rate by sex and age.[Results]A total of 1 369 cases of gallbladder cancer occurred in Qi-dong City from 1972 to 2021,accounting for 0.93％of all malignant tumors.The overall CR of gallbladder cancer was 2.44/105 in 50 years,ASRC was 0.88/105 and ASRW was 1.45/105.The truncated rate of 35～64 years old was 1.98/105,the cumulative incidence of gallbladder cancer at 0～74 years old was 0.16％,and the risk of cumulative incidence of gallbladder cancer was 0.16％.CR was slightly higher in women than that in men,but after standardization it was slightly higher in men than that in women.The sex ratio of CR,ASRC and ASRW was 0.89,1.07 and 1.06,respectively.With the increase of age,the incidence of gallbladder cancer was also increased.The age of onset was slightly increased in last 50 years.In last 50 years,there was an upward trend in the overall incidence of gallbladder cancer,the incidence both for men and women,and the inci-dence of each age group.[Conclusion]The incidence of gallbladder cancer in Qidong City has increased considerably during the past 50 years,and continuing attention should be paid to the prevention and treatment of gallbladder cancer especially for the key populations.

DNA repair is essential for the successful replication of genetic material and for transcriptional fidelity.Excision repair cross-complementation group 1(Ercc1)is a structure-specific nucleic acid endonuclease that repairs DNA damage by participating in the nucleotide excision repair and DNA double-strand break repair pathways.The accumulation of various types of molecular and cellular damage over time lead to aging.Defects in Ercc1 are associated with malfunctions in DNA damage repair,resultsing in the accumulation of cellular damage and ultimately inducing aging.This paper summarizes the biological functions of Ercc1 during DNA damage and the phenotypes of Ercc1-deficient mouse models,and discusses the biological effects of Ercc1 in different tissues associated with senescence and age-related degenerative diseases.This review highlights potential intervention targets and provides a theoretical basis for the development of innovative therapeutics,animal models,and drug discovery for senescence-associated diseases.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To analyze pancreatic cancer incidence and mortality data in China and worldwide and to provide data for pancreatic cancer prevention and control efforts.Methods:Data of pancreatic cancer incidence and mortality rates, along with historical and predictive data, were obtained from the GLOBOCAN 2022 database. Epidemiological characteristics of pancreatic cancer was analyzed by region, sex, age and Human Development Index (HDI). Spearman's correlation coefficient test was used to assess the relationship between HDI and age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR).Results:In 2022, the global number of new cases and deaths of pancreatic cancer will be 511 thousand and 467 thousand, respectively, with an ASIR and ASMR of 4.7/10 5 and 4.2/10 5, respectively. North America and Europe had the highest pancreatic cancer incidence and mortality rates of 8.5/10 5 and 7.3/10 5, respectively. Global ASIR and ASMR in men were both 1.4 times higher than those in women. HDI levels were positively correlated with ASIR ( r=0.79, P＜0.001) and ASMR ( r=0.78, P＜0.001) of pancreatic cancer in all regions. The number of pancreatic cancer cases and deaths in China were 119 thousand and 106 thousand, respectively, while the ASIR and ASMR of pancreatic cancer were 4.4/10 5 and 3.9/10 5, respectively. Both ASIR and ASMR in men were both 1.5 times higher than those in women in China. The number of pancreatic cancer incidence and death cases in China in 2050 is predicted to be 216 thousand and 204 thousand cases, with an increase of 81.5% and 92.5% compared with 2022, respectively. Conclusions:The disease burden of pancreatic cancer varies significantly among different regions, genders and ages. Pancreatic cancer incidence and mortality are positively correlated with HDI. The incidence and mortality rates of pancreatic cancer in China are close to the global average, but the number of new cases and deaths is high. Prevention and control should be strengthened to improve the survival of pancreatic cancer patients.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.
