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）］

Objective: To analyze the adverse treatment outcome status and spatio temporal characteristics of pulmonary tuberculosis cases among students in Qinghai Province, providing a reference basis for pulmonary tuberculosis prevention and control in schools. Methods: The data of student pulmonary tuberculosis cases during 2013-2023 in Qinghai Province were obtained through the "National Tuberculosis Management Information System", and the treatment outcome was retrospectively analyzed. The Joinpoint model was applied to analyze the adverse outcome rate trend. Global and local spatial autocorrelation analysis, and spatiotemporal scan cluster analysis were conducted on the adverse outcome rate of pulmonary tuberculosis among students in Qinghai Province. Results: During 2013-2023, 488 cases of adverse outcomes were reported among 6 155 students with pulmonary tuberculosis in Qinghai Province, with an adverse outcome rate of 7.93%. The reporting adverse outcome rate of pulmonary tuberculosis among students showed a downward trend from 2013 to 2023 (APC=-16.20, t =-3.89, P <0.05). The results of spatial autocorrelation showed that the adverse outcome rate of pulmonary tuberculosis was Moran s I >0 among students in Qinghai Province. Among them, there was a spatially positive correlation in the adverse outcome rate of pulmonary tuberculosis among students in 2020, 2021 and 2022(all Z >1.96, all P <0.05). The results of clustering and outlier analysis in local spatial autocorrelation showed that the areas with high high aggregation were mainly concentrated in Yushu Prefecture(Zhiduo County, Zaduo County, Nangqian County, Yushu City), Huangnan Prefecture (Zeku County, Henan County) and Hainan Prefecture (Tongde County). The low low concentration areas were distributed in Haidong City, Xining City, Haibei Prefecture (Gangcha County, Qilian County), Haixi Prefecture (Tianjun County, Ulan County), Hainan Prefecture (Gonghe County, Guide County) and Huangnan Prefecture (Tongren City, Jianzha County). The spatio temporal scanning showed that a total of two possible aggregation areas had been detected. Among them, the first level aggregation area composed of 10 counties and districts in Yushu Prefecture and Guoluo Prefecture of Qinghai Province, and the cluster radius was 658.09 km, the RR was 10.58 , and the LLR was 305.91; the second level aggregation area was composed of 16 counties and districts in Hainan Prefecture, Haixi Prefecture, Huangnan Prefecture and Guoluo Prefecture, and the cluster radius was 407.02 km, the RR was 9.83, and the LLR was 152.48 (both P <0.05). Conclusions The reporting rates of adverse treatment outcome of pulmonary tuberculosis cases among students in Qinghai Province remain relatively high and unevenly distribute throughout the province. Supervision should be strengthened to improve cases compliance,and to reduce student pulmonary tuberculosis adverse treatment outcomes incidence.

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 investigate the impact of donor kidney histopathological lesions on the risk of BK virus (BKV) infection and progression after kidney transplantation. Methods A retrospective analysis was conducted on the clinical data of 326 kidney transplant recipients from deceased donors at the Department of Kidney Transplantation, the First Affiliated Hospital of Zhengzhou University, from January 2019 to June 2020. The recipients were divided into two groups based on whether BKV infection occurred after kidney transplantation: the BKV infection group (145 cases) and the non-BKV infection group (181 cases). The correlation between donor kidney histopathological findings from zero-hour biopsy and BKV infection, as well as the impact on the risk and progression of BKV infection, was analyzed. Results The incidence of BKV infection among the 326 kidney transplant recipients was 44.5% (145/326). The clearance rate of BKV after infection was 82.1% (119/145), while 17.9% (26/145) progressed to BKV viremia. Among the 326 qualified kidney biopsy specimens, 32 cases showed mild tubular atrophy, 324 cases had mild acute tubular injury, 27 cases exhibited mild hyaline arteriosclerosis, 10 cases had moderate to severe hyaline arteriosclerosis, 7 cases showed mild interstitial inflammation, 23 cases had mild interstitial fibrosis, 6 cases exhibited mild arterial intimal fibrosis, and 1 case had moderate to severe arterial intimal fibrosis. Multivariate logistic regression analysis revealed that male recipients, donor age and tubular atrophy were independent risk factors for BKV infection (all P<0.05). Tubular atrophy was also an independent risk factor for the progression from BKV uria to BKV viremia (P<0.05). Conclusions Donor kidney histopathological lesions have a certain impact on BKV infection and progression after kidney transplantation. Patients with more severe tubular atrophy in donor kidneys have a higher risk of BKV infection after kidney transplantation and are more likely to progress to BKV viremia.

Objective: To explore the facilitating and hindering factors of mental health promotion activities in junior and senior high schools from teachers perspectives, as well as coping strategies, so as to provide evidence for implementing teacher led mental health promotion programs. Methods: From September 2023 to September 2024, by using purposive sampling method, 5 junior high schools, 5 regular high schools, 2 vocational high schools in four provinces and municipalities (Tianjin, Shanxi, Shandong, and Jiangxi) were selected. A total of 92 teachers (78 homeroom teachers and 14 full time or part time psychological counselors) were interviewed using semi structured focus group discussions (one session per school, totaling 12 sessions). Thematic analysis was applied to code and analyze the interview transcripts. Results: The implementation of mental health promotion activities in middle schools was influenced by three levels: teachers, schools and society. Specifically, teachers exhibited a high support low capability phenomenon (81 participants supported conducting such activities, but 71 felt lacking in professional capacity); activity effectiveness and support systems were imbalanced (42 mentioned significant effects, while 78 reported insufficient support); there was a mismatch between student demand and activity content (9 mentioned students had psychological needs, but 11 indicated existing activities failed to meet these needs); administrative support and sustainability showed disparities (14 believed sufficient administrative support existed, while 37 noted sustainability issues); parental awareness and participation remained inadequate (11 highlighted parents need for mental health knowledge, and 37 perceived insufficient understanding of psychological issues among parents). Effective strategies included enhancing teachers effectiveness, providing essential skill training, focusing on the needs of teenagers,enhancing program sustainability, and eliminating misconceptions about mental health among parents. Conclusion Mental health promotion activities in junior and senior high schools should focus on enhancing teachers skills, improving activity sustainability, reducing stigma among parents, and establishing a collaborative network for school based mental health promotion.

OBJECTIVE: To review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. METHODS: A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into "U" type (9 cases), "H" type (7 cases), "T" type (4 cases), and "λ" type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. RESULTS: All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one ( t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] ( t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). CONCLUSION SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.

Background:To compare the efficacy and safety of monthly administrations of gonadotropin releasing hormone (GnRH) agonists LY01005 and Zoladex ? in Chinese patients with premenopausal breast cancer. Methods:From October 2020 to November 2021, 188 premenopausal breast cancer patients were enrolled in 34 hospitals and randomized 1:1 to receive either LY01005 or Zoladex ? every 28 days for a total of three injections. All patients concomitantly received oral tamoxifen (TAM). The primary efficacy endpoint was cumulative probability of maintaining menopausal level [oestradiol (E2) ≤30 pg/ml] from day 29 to day 85. The second efficacy endpoint included changes in E2, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) compared with the baseline. Pharmacokinetics (PK), pharmacodynamics (PD), and safety were analyzed. The study also evaluated the pharmacokinetic and pharmacodynamic characteristics of LY01005. Results:A total of 188 patients were randomised and 187 patients received either LY01005 or Zoladex ?. Cumulative probabilities of maintaining menopausal level (E2≤30 pg/ml) from day 29 to day 85 were 93.1% for LY01005 and 86.3% for Zoladex ?. The between-group difference was 6.8% (95% CI: -2.3%, 15.9%) and primary efficacy in the LY01005 group was not inferior to that in the Zoladex ? group. Changes in E2, LH, and FSH levels compared with the baseline were equivalent between the two groups (E2: 89.34% to 90.23% vs. 82.11% to 85.02%; LH: 88.89% to 95.52% vs. 89.70% to 97.02%; FSH: 75.36% to 80.85% vs.73.07% to 80.24%, respectively). After three consecutive doses of LY01005, the LH and FSH levels of the subjects showed a transient increase after the first dose, reached a peak on the second day and then started to decrease. The LH and FSH reached a lower level and remained at or below that level until the 85th day. Both treatments were well-tolerated. Conclusion:LY01005 is as effective as Zoladex ? in suppressing E2 to menopausal levels in Chinese patients with premenopausal breast cancer, with a similar safety profile.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

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.
