Objective: To analyze the developmental trajectories of clustered health risk behaviors and their association with self-esteem and lonelinesss among junior high school students, so as to provide a reference for formulating comprehensive prevention and control measures of health risk behaviors among adolescents. Methods: In October 2023, 1 165 first year junior high school students from two schools of Jishou City in Hunan Province were selected by convenient sampling method for three follow up surveys (T1:October 2023; T2:April 2024; T3:October 2024). The Adolescent Health Risk Behavior Questionnaire, Rosenberg Self esteem Scale and Loneliness Scale were used to assess health risk behaviors, self esteem and loneliness, respectively. Latent growth curve modeling and latent growth mixture modeling were applied to analyze the developmental trajectories of clustered health risk behaviors among junior high school students. Logistic regression was used to analyze the association of the developmental trajectories of clustered health risk behaviors with self esteem and loneliness among junior high school students. Results: The overall developmental trajectories among junior high school students showed a declining trend (intercept=0.15, slope=-1.65, both P <0.05), with three heterogeneous categories:low risk improvement group ( n =862, 74.0%), moderate risk stable group ( n =260, 22.3%), and high risk deterioration group ( n =43, 3.7%). After adjusting the status of the left behind individuals，using the low risk improvement group as the reference category in multinomial Logistic regression analysis, results indicated that higher loneliness scores among junior high school students increased the risks of belonging to the moderate risk stable group ( OR=1.02, 95%CI =1.00- 1.04 ) and the high risk deterioration group ( OR=1.04, 95%CI =1.00-1.08), while higher self esteem scores reduced the risks of belonging to the moderate risk stable group ( OR=0.93, 95%CI =0.91-0.96) and the high risk deterioration group ( OR=0.88, 95%CI =0.83-0.94) (all P <0.05). Conclusions The overall trend of clustered health risk behaviors among junior high school students gradually improves, and the self esteem and loneliness are significant correlative factors. Targeted intervention measures should be developed for the junior high school students, with a focus on enhancing their self esteem and alleviating loneliness.

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）］

ObjectiveTo systematically review the effect of dual-task training (DTT) on mobility and balance in stroke patients. MethodsCNKI, Wanfang Data, VIP, PubMed, Web of Science, Embase and Cochrane Library were searched for randomized controlled trials (RCT) on DTT in stroke rehabilitation from inception to June, 2025. The quality of the included studies was assessed using the Cochrane Risk of Bias Tool and the PEDro scale. Meta-analysis was performed using RevMan 5.4. ResultsA total of eleven RCT involving 517 stroke patients were included, and the scores of PEDro scale were four to eight. DTT was more effective on the score of Fugl-Meyer Assessment-Lower Extremity (MD = 3.70, 95%CI 1.88 to 5.53, P < 0.001) and Berg Balance Scale (BBS) (MD = 3.04, 95%CI 1.58 to 4.49, P < 0.001), fall incidence (OR = 0.32, 95%CI 0.11 to 0.87, P = 0.025), gait speed under a single-task condition (MD = 0.08, 95%CI 0.03 to 0.12, P = 0.002), gait speed under a dual-task condition (MD = 0.13, 95%CI 0.10 to 0.16, P < 0.001), Timed Up and Go Test time (MD = -2.78, 95%CI -3.85 to -1.72, P < 0.001), and score of modified Barthel Index (MD = 4.77, 95%CI 1.88 to 7.66, P = 0.001). Subgroup analysis indicated that motor-motor DTT was more effective than cognitive-motor DTT on BBS scores and single-task gait speed. ConclusionsDTT can improve mobility and balance in stroke patients, especially with motor-motor tasks.

Hepatolenticular degeneration （HLD），also known as Wilson disease (WD) is an uncommon hereditary disorder of the nervous system， characterized by hepatic impairment， extrapyramidal manifestations， psychiatric symptoms， and renal dysfunction， while impaired vision is a rare comorbidity. This article conducts a retrospective analysis of visual acuity changes， treatment， and prognosis of a female patient， aged 22 years， who were diagnosed with HLD complicated by bilateral neuritis in an affiliated hospital of Anhui University of Chinese Medicine in 2022， and a literature review was performed. The findings suggest that impaired vision is a rare manifestation of HLD. Ophthalmologists should consider the possibility of HLD in patients with optic atrophy and optic neuritis， and early intravenous administration of methylprednisolone may help to improve prognosis.

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.

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.

Osteoradionecrosis of the jaws (ORNJ) is among the most severe oral complications following radiotherapy for head and neck tumors. It is essentially a form of pathological necrosis of the jawbone induced by radiation therapy. ORNJ is defined as bone damage, primarily characterized by inflammation and necrosis, occurring in the jawbone within the irradiated area and accompanied by soft tissue injury, persisting for more than 3 months without spontaneous healing. Diagnosis requires exclusion of other potential etiologies, including primary tumor recurrence, medication-related osteonecrosis, and radiation-induced neoplasms of the jawbone, etc. In this review, recent advances in the epidemiology, risk factors, diagnosis, classification and staging, dosimetric parameters, pathogenesis, treatment, and prevention of radiation-induced osteonecrosis of the jaws were summarized.

Objective:To investigate the effects of different doses of whole abdominal ultra‐high dose rate (FLASH) irradiation on the intestinal microbiota of mice.Methods:A total of 25 healthy male C57BL/6J mice were randomly divided into the control ( n=5) and FLASH irradiation groups ( n=20) by simple randomization method, and the FLASH irradiation group was further divided into different radiation dose subgroups of 10, 15, 20, 25 Gy, 5 in each group. The mice were irradiated with a single whole abdomen at a dose rate of 100 Gy/s, then sacrificed 3.5 d after irradiation. Fresh fecal specimens and intestinal tissues of mice were collected for 16S rRNA sequencing, microbiota analysis, hematoxylin eosin (HE) staining and injury severity score analysis. Two-group comparison was performed by independent sample t-test. Multi-group comparison was conducted by one-way ANOVA. Results:HE staining revealed that the whole abdomen FLASH irradiation caused varying degree of intestinal injury in mice, and the intestinal injury reaction was aggravated with the increase of irradiation dose. β‐diversity analyses showed that there were differences in the composition of intestinal microbiota between FLASH irradiation group and control group ( P=0.001), but the differences in the relative abundance of the species between the irradiation groups at different doses were relatively small, and there were their own dominant genera of bacteria. Comparison of different doses of FLASH irradiation groups with control group screened out 16 species of bacteria with shared differences at the genus level, in which Lactobacillus, Ligilactobacillus and unclassified Lactobacillus were more abundant in the control group, while Escherichia, Allobaculum, and Muribaculum were more abundant in the FLASH irradiation groups. Conclusions:The whole‐abdominal FLASH irradiation induces intestinal damage in mice, and the intestinal damage response is worsened with the increase of irradiation dose. Different doses of whole abdominal FLASH irradiation alter the intestinal microbiota composition of mice. Sixteen species of common intestinal differential microbiota at the genus level are screened out in the different doses of FLASH irradiation groups compared with the control group, which may serve as a marker for measuring intestinal injury in mice irradiated with whole‐abdominal FLASH.

Saponins associated with Panax notoginseng (P. notoginseng) demonstrate significant therapeutic efficacy across multiple diseases. However, certain high-yield saponins face limited clinical applications due to their reduced pharmacological efficacy. This study synthesized and evaluated 36 saponin-1,2,3-triazole derivatives of ginsenosides Rg1/Rb1 and notoginsenoside R1 for anti-adipogenesis activity in vitro. The research revealed that the ginsenosides Rg1-1,2,3-triazole derivative a17 demonstrates superior adipogenesis inhibitory effects. Structure-activity relationships (SARs) analysis indicates that incorporating an amidyl-substituted 1,2,3-triazole into the saponin side chain via Click reaction enhances anti-adipogenesis activity. Additionally, several other derivatives exhibit general adipogenesis inhibition. Compound a17 demonstrated enhanced potency compared to the parent ginsenoside Rg1. Mechanistic investigations revealed that a17 exhibits dose-dependent inhibition of adipogenesis in vitro, accompanied by decreased expression of preadipocytes. Peroxisome proliferator-activated receptor γ (PPARγ), fatty acid synthase (FAS), and fatty acid binding protein 4 (FABP4) adipogenesis regulators. These findings establish the ginsenoside Rg1-1,2,3-triazole derivative a17 as a promising adipocyte differentiation inhibitor and potential therapeutic agent for obesity and associated metabolic disorders. This research provides a foundation for developing effective therapeutic approaches for various metabolic syndromes.
