Objective: To explore the relationship between life skills, psychological resilience and subjective well-being among primary and secondary school students, so as to provide evidence for targeted adolescent mental health education. Methods: From September to November, 2025, a total of 5 831 primary and secondary school students from five cities (Beijing, Guangzhou, Shenzhen, Chongqing, Urumqi) were selected by convenience sampling. The Adolescent Subjective Well being Scale, School based Adolescents Life Skills Scale, and Adolescent Psychological Resilience Scale were used for investigation. Data were analyzed using t-tests, one way ANOVA, and linear regression. Results: The total mean score of students subjective well being was (5.46± 0.91) ; the total mean score of life skills was (3.69±0.64); the total mean score of psychological resilience was (3.66±0.69). Statistically significant differences in subjective well being scores were found among students grouped by gender, grade, school stage, residential city, living with parents or living with siblings ( t/F =4.14, 53.92, 14.53, 49.99, 13.49, 2.18, all P <0.01). Stratified regression analyses were performed by gender (adjusting for school stage, residential city and living arrangement) and by school stage (adjusting for gender, residential city and living arrangement), the regression results indicated that life skills of boys, girls, primary school students and junior high school students( β =0.54, 0.53, 0.50, 0.57) and their psychological resilience ( β = 0.56 , 0.60, 0.56, 0.60) were positively associated with subjective well being (all P <0.01). Conclusions Life skills and psychological resilience may be important protective factors for subjective well being among primary and secondary school students. School based mental health education should emphasize life skills training and resilience building to promote students subjective well being.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Instrument separation is a critical complication during root canal therapy, impacting treatment success and long-term tooth preservation. The etiology of instrument separation is multifactorial, involving the intricate anatomy of the root canal system, instrument-related factors, and instrumentation techniques. Instrument separation can hinder thorough cleaning, shaping, and obturation of the root canal, posing challenges to successful treatment outcomes. Although retrieval of separated instrument is often feasible, it carries risks including perforation, excessive removal of tooth structure and root fractures. Effective management of separated instruments requires a comprehensive understanding of the contributing factors, meticulous preoperative assessment, and precise evaluation of the retrieval difficulty. The application of appropriate retrieval techniques is essential to minimize complications and optimize clinical outcomes. The current manuscript provides a framework for understanding the causes, risk factors, and clinical management principles of instrument separation. By integrating effective strategies, endodontists can enhance decision-making, improve endodontic treatment success and ensure the preservation of natural dentition.

BACKGROUND: The use of inserted sham acupuncture as a placebo in randomized controlled trials (RCTs) is controversial, because it may produce specific effects that cause an underestimation of the effect of acupuncture treatment. OBJECTIVE: This systematic survey investigates the magnitude of insert-specific effects of sham acupuncture and whether they affect the estimation of acupuncture treatment effects. SEARCH STRATEGY: PubMed, Embase and Cochrane Central Register of Controlled Trials were searched to identify acupuncture RCTs from their inception until December 2022. INCLUSION CRITERIA: RCTs that evaluated the effects of acupuncture compared to sham acupuncture and no treatment. DATA EXTRACTION AND ANALYSIS: The total effect measured for an acupuncture treatment group in RCTs were divided into three components, including the natural history and/or regression to the mean effect (controlled for no-treatment group), the placebo effect, and the specific effect of acupuncture. The first two constituted the contextual effect of acupuncture, which is mimicked by a sham acupuncture treatment group. The proportion of acupuncture total effect size was considered to be 1. The proportion of natural history and/or regression to the mean effect (PNE) and proportional contextual effect (PCE) of included RCTs were pooled using meta-analyses with a random-effect model. The proportion of acupuncture placebo effect was the difference between PCE and PNE in RCTs with non-inserted sham acupuncture. The proportion of insert-specific effect of sham acupuncture (PIES) was obtained by subtracting the proportion of acupuncture placebo effect and PNE from PCE in RCTs with inserted sham acupuncture. The impact of PIES on the estimation of acupuncture's treatment effect was evaluated by quantifying the percentage of RCTs that the effect of outcome changed from no statistical difference to statistical difference after removing PIES in the included studies, and the impact of PIES was externally validated in other acupuncture RCTs with an inserted sham acupuncture group that were not used to calculate PIES. RESULTS: This analysis included 32 studies with 5492 patients. The overall PNE was 0.335 (95% confidence interval [CI], 0.255-0.415) and the PCE of acupuncture was 0.639 (95% CI, 0.567-0.710) of acupuncture's total effect. The proportional contribution of the placebo effect to acupuncture's total effect was 0.191, and the PIES was 0.189. When we modeled the exclusion of the insert-specific effect of sham acupuncture, the acupuncture treatment effect changed from no difference to a significant difference in 45.45% of the included RCTs, and in 40.91% of the external validated RCTs. CONCLUSION The insert-specific effect of sham acupuncture in RCTs represents 18.90% of acupuncture's total effect and significantly affects the evaluation of the acupuncture treatment effect. More than 40% of RCTs that used inserted sham acupuncture would draw different conclusions if the PIES had been controlled for. Considering the impact of the insert-specific effect of sham acupuncture, caution should be taken when using inserted sham acupuncture placebos in RCTs.

Objective To observe the repair effect and mechanism of Danhuang Powder-containing serum on high glucose-induced vascular endothelial cell injury.Methods Danhuang Powder-containing serum was prepared.Human umbilical vein endothelial cells(HUVECs)were cultured to be divided into control group,recombinant human epidermal growth factor(called"growth factor"for short)group,Danhuang Powder group,high glucose group,high glucose+growth factor group,and high glucose+Danhuang Powder group.After corresponding intervention in each group for 48 hours,the cell ultrastructure and autophagy were observed under transmission electron microscope,apoptosis was detected by flow cytometry,and the protein expression levels of vascular endothelial growth factor(VEGF),epidermal growth factor(EGF)and basic fibroblast growth factor(bFGF)in the cells were detected by Western Blot.Results(1)The intra-mitochondrial ridges in the control group were clearly visible,autophagosomes and autolysosomes were fewer;mitochondria in the high glucose group were swollen and irregular,and appeared vacuolated;and the more typical autophagy-like structures were seen in the high glucose+Danhuang Powder group.(2)Compared with the high glucose group and high glucose+growth factor group,the apoptosis rate of cells in the high glucose+Danhuang Powder group was significantly decreased(P<0.05).(3)Compared with the high glucose group and the high glucose+growth factor group,the protein expression levels of VEGF,EGF and bFGF in the cells of the high glucose+Danhuang Powder group were significantly increased(P<0.05).Conclusion Danhuang Powder-containing serum can reduce the high glucose-induced damage in HUVEC cells,and its mechanism may be related to the activation of mitochondrial autophagy,and the inhibition of apoptosis,as well as the up-regulation of the expression of VEGF,EGF and bFGF.

Objective To investigate the association between birth weight and dementia risk and the mediating roles of chronic diseases,and to assess potential biological pathways underlying the birth weight-associated dementia risk based on large-scale proteomics.Methods We used data from 279 743 participants aged 40 to 69 years enrolled in the UK Biobank.Birth weight was categorized into low birth weight(≤2 500 g),normal birth weight(2 500-3 999 g),and macrosomia(≥4 000 g).Multivariable Cox proportional hazards regression models were used to assess the associations between birth weight categories and all-cause dementia and its subtypes(Alzheimer's disease and vascular dementia).Proteomics analyses were conducted to identify proteins and the potential pathways involved.Results Low birth weight was associated with higher risks for all-cause dementia and its subtypes.The hazard ratios were 1.18(95%CI,1.08-1.30)for all-cause dementia,1.14(95%CI,1.00-1.31)for Alzheimer's disease,and 1.22(95%CI,1.01-1.48)for vascular dementia.A non-linear relationship was observed between birth weight and dementia risk(P for nonlinearity<0.001).Certain cardiometabolic diseases in middle-aged adults,such as diabetes,stroke,hypertension,and dyslipidemia,played a significant mediating role in the relationship between low birth weight and dementia risk,with the mediation proportion being 6.3%to 15.8%.Proteomic analyses identified 21 proteins linked to both low birth weight and all-cause dementia risk,which were significantly enriched in the pathways for viral protein interaction with cytokines and cytokine receptors,adipocytokine signaling,and cytokine-cytokine receptor interaction.Conclusion Low birth weight is positively associated with dementia risk.Cardiometabolic diseases in middle-aged adults may mediate the relationship between low birth weight and dementia risk.A number of proteins and the associated pathways underscore the relationship between low birth weight and dementia risk.

On October 9th,2023,the Disease Control and Prevention Center of Donghu High Tech Zone in Wuhan City received a report of a case of imported malaria.The patient was admitted due to intermittent fever that had persisted for 3 days,accompanied by a 1 h consciousness disorder,and the family of the patient reported a recent history of travel to the Democratic Republic of Congo in Africa.Upon admission,the rapid diagnostic method(RDT)was used to test for malarial parasite antigens and peripheral blood smear microscopy was performed to detect the presence of malignant malaria parasites.On the basis of epidemiology,clinical symptoms,and laboratory testing,a diagnosis of severe malignant malaria was made,and immediate standardized anti-malarial treatment was accordingly administered.After 4 days of treatment,peripheral blood smear microscopy revealed no plasmodium parasites observed.After 37 days,the patient was recovered and discharged from the hospital.

Objective:To assess the use of R-R interval (RRI) sequence data collected via wearable devices to evaluate emotional dynamic factors in adolescents with depressive disorders, and to analyze their impact on diagnosis and severity assessment.Methods:Clinical data were prospectively collected from 154 adolescent inpatients with depressive disorders (132 females, 22 males; age 12-18, mean: 13.5±1.6 years) treated at the Child Psychiatry Ward of Beijing Anding Hospital, Capital Medical University between January 2023 and January 2024.A control group of 152 healthy adolescents (62 females, 90 males; age 12-18, mean 14.5±1.3 years) was recruited during the same period. RRI data were obtained using the built-in photoplethysmography (PPG) sensor in the HUAWEI Band 7 wearable device. The device′s integrated emotion evaluation system extracted arousal and emotional valence (as indicators of emotional dynamics) from the collected RRIs. A Long Short-Term Memory (LSTM) network was employed to develop a model for depression diagnosis and severity prediction, while a random forest model was applied to generate receiver operating characteristic (ROC) curves to evaluate model performance. Binary Logistic regression was conducted to investigate the influence of arousal and emotional valence on depression diagnosis and severity.Results:A total of 429 records were collected and analyzed from 306 participants. The LSTM-based diagnosis and severity assessment models achieved area under the curve (AUC) of 0.896 9 and 0.715 3, respectively, indicating good model performance. Binary Logistic regression analysis showed that arousal and emotional valence had significant effects on diagnosis and severity. Specially, lower arousal in both the first 4 hours ( β=-8.906, 95%CI:-17.497 to -0.315) and second 4 hours ( β=-3.033, 95%CI:-5.109 to -0.957) significantly predicted positive depression diagnosis ( β=-1.219, 95%CI:-2.205 to -0.233), while emotional valence in the second 4 hours showed a trend toward a positive association ( β=0.675, 95%CI:-0.107-1.457). First 4-hour emotional valence: significantly positive association with severity ( β=0.322, 95%CI: 0.067-0.577), second 4-hour arousal level: negative association with severity ( β=-0.258, 95%CI:-0.527 to 0.011), whereas arousal in the second 4 hours had a marginal negative effect (β=-0.258, 95% CI:-0.527 to 0.011). Conclusion:RRI may serve as a useful auxiliary measure in diagnosing depressive disorders and predicting severity among adolescents. Wearable smart devices offer promising potential for screening emotional dynamic factors related to adolescent depression.
