Background Carbendazim (CBZ), a widely used benzimidazole fungicide, has raised increasing concerns regarding the health risks associated with its residues. However, the toxic effects and associated mechanisms of CBZ on the skeletal system have not been reported. Objective To elucidate the effects of carbendazim on osteogenic differentiation and its underlying mechanisms. Methods MC3T3-E1 mouse pre-osteoblastic cells were treated with 1, 10, and 100 μmol·L−1 CBZ for 24 h to examine cell viability, alkaline phosphatase (ALP) activity, bone nodule formation, reactive oxygen species (ROS) level, malondialdehyde (MDA) content, and nitric oxide synthase (NOS) activity. Transcriptomics was used to identify differentially expressed genes (DEGs) in osteoblasts exposed to CBZ. Kyoto Encyclopedia of Genes and Genomes (KEGG) and gene set enrichment analysis (GSEA) were employed to analyze the potential biological pathways of DEGs. Real-time polymerase chain reaction (RT-PCR) and Western blot were used to validate changes in gene and protein expression. Results Exposure to 10 and 100 μmol·L−1 CBZ significantly reduced osteoblast viability, ALP activity, bone nodule formation, and NOS activity, while increasing intracellular ROS levels. CBZ at 100 μmol·L−1 concentration significantly elevated MDA level (P < 0.05). The transcriptomic analysis revealed that 1 μmol·L−1 CBZ treatment resulted in 385 significantly DEGs. The KEGG enrichment analysis revealed that CBZ significantly affects hormone regulation pathways (including parathyroid hormone, growth hormone, dopamine, and oxytocin), mitogen-activated protein kinase (MAPK) and cyclic GMP-dependent protein kinase G (cGMP-PKG) signaling pathways, focal adhesion and adherens junction, as well as the NOD-like receptor signaling pathway and the mRNA surveillance (NMD) pathway. The results of GSEA showed that CBZ significantly inhibited the bile acid metabolism and the Wnt/β-catenin pathway in osteoblasts. The validation results demonstrated that CBZ significantly suppressed the mRNA expression of Wnt3a and β-catenin, as well as the protein expression of Runx2 and Osterix in the Wnt/β-catenin pathway. Conclusion CBZ exposure exhibits potential skeletal toxicity, and its mechanism is through promoting oxidative stress, interfering with the Wnt/β-catenin pathway in osteogenic differentiation, thereby inhibiting the bone formation function of osteoblasts.

ObjectiveTo explore the biological mechanism of bone loss caused by perfluorooctanoic acid (PFOA) through transcriptomic analysis, and to provide new insights into regulating perfluoroalkyl substances (PFAS) applications and the prevention of hazards affecting bone health. MethodsMouse embryonic osteoblast precursor cells (MC3T3-E1) were exposed to 0.1, 1, 10, and 100 μmol·L-¹ PFOA for 24 hours to assess the effects on cell viability and alkaline phosphatase (ALP) activity, and to determine the critical concentration of PFOA toxicity. The transcriptome sequencing (RNA-seq) was performed to identify differentially expressed genes (DEGs) induced by PFOA. Gene ontology (GO) analysis and gene set enrichment analysis (GSEA) were conducted to identify significantly affected gene pathways. Additionally, Seahorse XF metabolic phenotyping and reverse transcription polymerase chain reaction (RT-PCR) were used to validate the key pathways. ResultsExposure to 10 and 100 μmol·L-¹ PFOA significantly reduced the cell viability and ALP activity of MC3T3-E1 cells. Therefore, the results of transcriptomic analysis for 10 μmol‧L-1 PFOA exposure found that a total of 80 DEGs were identified, including 32 upregulated genes and 48 downregulated genes. According to GO analysis, PFOA mainly affected cellular components such as mitochondrion and nucleus, molecular functions involving GTPase activity and GTP binding, as well as biological process related to mRNA processing. GSEA identified the downregulation of the β-oxidation of fatty acid pathway in mitochondria. Metabolic phenotyping reserches showed that PFOA indeed reduced mitochondrial aerobic respiration capacity and adenosine triphosphate (ATP) production, and the ratio of ATP production from cellular aerobic respiration to glycolysis was significantly decreased as well. The mRNA expression of glucose metabolism-related genes (GK, G6PD, and CS), as well as fatty acid metabolism-related genes (CPT1A and CPT2), were significantly downregulated. ConclusionPFOA reduces bone formation by inhibiting energy metabolism and β-oxidation of fatty acid pathways in osteoblasts, whihc lays the foundation for revealing the mechanism of PFOA exposure induced bone loss.

Chinese Journal of School Health 2025;46(10):1411-1415
Objective:
To analyze the association between altitudes and nutritional status of children and adolescents, and to explore the moderating effects of dietary behaviors and physical activity, so as to provide a scientific basis for developing lifestyle interventions tailored to local conditions.
Methods:
From September to November 2023, physical examinations and questionnaire surveys were conducted among children and adolescents aged 7-17 in two autonomous regions, Inner Mongolia and Xizang, with a final sample of 156 511 participants by the stratified cluster random sampling method. Height and weight were measured to calculate body mass index (BMI). Sociodemographic characteristics, dietary behaviors, and physical activity were collected via questionnaires, while the altitude of each participant s school was obtained using Amap. Logistic regression was performed to examine the relationship between altitudes and nutritional status. Interaction terms and stratified analyses were applied to assess the moderating effects of dietary behaviors and physical activity. Restricted cubic spline (RCS) were used for visualization.
Results:
In 2023, the prevalence of wasting and overweight/obesity among children and adolescents in Xizang were 9.7% and 9.0%, respectively, compared to 2.9% and 22.0% in Inner Mongolia. Logistic regression analysis results showed that for every 1 km increase in altitude, the risk of wasting increased, while the risk of overweight/obesity decreased ( OR =1.43, 0.19, both P <0.05). The results of the stratified analysis showed that compared to those living at altitudes <1 km, children and adolescents with healthy diets showed no significant association between altitudes (1-<2 and 2-<3 km) and wasting ( OR =1.22, 0.75, both P >0.05), whereas significant associations were observed at 3-<4 and ≥4 km altitudes ( OR =2.25, 2.89, both P <0.05). In contrast, unhealthy dietary groups showed statistically significant associations across altitudes ( OR =1.18-4.04, all P <0.05), consistent with RCS results. No moderating effects were observed for physical activity on the altitude wasting association or for dietary behaviors and physical activity combined on the altitude overweight/obesity association ( P interaction =0.63, 0.10, 0.53).
Conclusion
Healthy dietary behaviors play a critical role in improving the nutritional status of children and adolescents and reducing regional disparities, providing a scientific foundation for public health policy formulation and implementation.

OBJECTIVE:
To construct a predictive model for the reduction in methadone maintenance treatment (MMT) and evaluate the effects of different interventions and other clinical factors on methadone reduction using Shapley additive explanations (SHAP).
METHODS:
Two clinical trials of acupuncture for methadone reduction in MMT patients were analyzed, and the baseline data, MMT related information, intervention measures, the data related to dose-reduction outcomes were collected. The predictive model was constructed by means of 6 machine learning algorithms including support vector machine (SVM), K-nearest neighbors (KNN), logistic regression (LR), Naive Bayes (NB), random forest (RF) and categorical-boosting (CatBoost), and 2 integration methods, blending-ensemble method (Blending) and Stacking-ensemble method (Stacking). SHAP was employed for the interpretability analysis of the optimal model.
RESULTS:
A total of 251 MMT patients were included, 128 cases in the acupuncture group and 123 cases in the non-acupuncture group. CatBoost and Stacking performed optimally in the test set. CatBoost obtained an accuracy of 0.780 0±0.060 8, a precision of 0.500 0±0.120 0, a recall of 0.818 2±0.140 2, F1 score of 0.620 7±0.114 0, and receiver operating characteristic-area under curve (ROC-AUC) of 0.857 8±0.140 2 for the subjects. In MMT patients with acupuncture as an adjunctive therapy, the top 5 important features for methadone reduction, included intervention measures, body mass index (BMI), the duration of MMT, the history of opioid use and occupation; and SHAP values were 1.25, 0.36, 0.21, 0.19 and 0.12, respectively. The SHAP feature dependence plot showed that BMI, MMT duration and the history of opioid use presented a nonlinear negative correlation with the reduction effect.
CONCLUSION
In acupuncture as adjunctive therapy for methadone reduction, the clinical factors should be considered comprehensively; and the interpretable predictive model provides a scientific basis for it, which is conducive to the improvement of clinical strategy of acupuncture for methadone reduction and the development of personalized reduction scheme.

Objective:To evaluate the efficacy and safety of therapeutic temperature control in patients with severe traumatic brain injury (sTBI).Methods:The full-text databases of Chinese Medical Journal, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Database, China Biomedical Database, PubMed, Embase, and Cochrane Library were searched for randomized controlled trials (RCTs) of hypothermia treatment and conventional treatment in patients with sTBI. The search period was from January 2016 to June 2025. Meta-analysis was performed using RevMan 5.3 software. The evaluation indicators included intracranial pressure before treatment, at 3 and 5 days after treatment, favorable prognosis rate and mortality rate within 6 months after treatment, and incidence of pulmonary infection, intracranial infection, epilepsy, acute gastrointestinal dysfunction, deep vein thrombosis, abnormal coagulation function, and arrhythmia during treatment; publication bias.Results:A total of 33 studies involving 3 322 patients were included, with 1 696 patients in the temperature treatment group and 1 626 in the conventional treatment group. There was no statistically significant difference in intracranial pressure between the two groups before treatment ( SMD=0, 95% CI -0.13, 0.14, P>0.05). However, at 3 and 5 days after treatment, the intracranial pressure was lower in the temperature treatment group than that in the conventional treatment group ( SMD=-2.29, 95% CI -2.76, -1.82, P<0.01; SMD=-2.66, 95% CI -3.43, -1.89, P<0.01). Within 6 months after treatment, the favorable prognosis rate was higher in the temperature treatment group than that in the conventional treatment group ( RR=1.41, 95% CI 1.32, 1.50, P<0.01), and mortality rate was lower than that in the conventional treatment group ( RR=0.64, 95% CI 0.55, 0.75, P<0.01). Compared with the conventional treatment group, the incidences of epilepsy and acute gastrointestinal dysfunction in the temperature treatment group were statistically reduced ( RR=0.33, 95% CI 0.13, 0.83, P<0.05; RR=0.43, 95% CI 0.25, 0.74, P<0.05). There were no statistically significant differences in the incidence of pulmonary infection ( RR=0.96, 95% CI 0.85, 1.08, P>0.05), intracranial infection ( RR=0.56, 95% CI 0.20, 1.56, P>0.05), deep vein thrombosis ( RR=0.93, 95% CI 0.69, 1.25, P>0.05), abnormal coagulation function ( RR=1.19, 95% CI 0.43, 3.31, P>0.05) or arrhythmia ( RR=0.51, 95% CI 0.23, 1.12, P>0.05) between the two groups. Egger′s test indicated the presence of publication bias and the results remained robust after trim and fill analysis. Conclusions:For patients with sTBI, temperature control therapy shows lowered intracranial pressure and mortality rate as well as improved favorable prognosis rate at 6 months posttreatment, and decreased incidence of epilepsy and acute gastrointestinal dysfunction during treatment, while reveals similar incidence of pulmonary infection, intracranial infection, deep vein thrombosis, abnormal coagulation function, and arrhythmia when compared with conventional treatment.

Objective:To investigate the prognosis of postoperative adjuvant therapy for hepatocellular carcinoma after conversion therapy of combined targeted therapy and immunotherapy followed by sequential hepatectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 103 patients with initially unresectable hepatocellular carcinoma (HCC) who were admitted to 11 medical centers in China, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from November 2019 to May 2023 were collected. There were 83 males and 20 females, aged (54±12)years. All 103 patients underwent conversion therapy of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) successfully followed by sequential hepatectomy, of which 72 patients undergoing postoperative adjuvant therapy were divided into the adjuvant therapy group, and 31 patients undergoing postoperative follow-up monitoring were divided into the follow-up monitoring group. Observation indicators: (1) follow-up and postoperative condi-tions; (2) analysis of factors influencing recurrence-free survival time of patients; (3) stratified ana-lysis. Comparison of count data between group was conducted using the chi-square test or Fisher exact probability. The R software was used to draw survival curves, and the Log-rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the Cox proportional hazard model. Results:(1) Follow-up and postoperative conditions. All 103 patients were followed up for 21.0(range, 1.9?47.2)months, with the median recurrence-free survival time of 28.7 months and the 1-, 2-, 3-year recurrence-free survival rates of 68.6%, 55.6%, 41.2%. The median overall survival time of 103 patients was unreached, and the 1-, 2-, 3-year overall survival rates were 90.9%, 82.1%, 69.6%, respectively. The median recurrence-free survival time was 33.1 months in patients of the adjuvant therapy group, with the 1-, 2-year recurrence-free survival rates as 77.2%, 61.5%. The median recurrence-free survival time was 11.1 months in patients of the follow-up monitoring group, with the 1-, 2-year recurrence-free survival rates as 46.6%, 40.8%. There was a significant difference in recurrence-free survival between the two groups of patients ( χ2=5.492, P<0.05). (2) Analysis of factors influencing recurrence-free survival time of patients. Results of multivariate analy-sis showed that pathologic complete response and postoperative adjuvant therapy were independent factors influencing recurrence-free survival time of HCC patients undergoing conversion therapy of combined targeted therapy and immunotherapy followed by sequential hepatectomy ( hazard ratio=0.297, 0.492, 95% confidence interval as 0.137?0.647, 0.268?0.903, P<0.05). (3) Stratified analysis. Of the 71 patients with non-pathologic complete response, the median recurrence-free survival time of 48 patients in the adjuvant therapy group was 24.0 months, with the 1-, 2-year recurrence-free survival rates as 67.4%, 48.8%. The median recurrence-free survival time of 23 patients with non-pathological complete response in the follow-up monitoring group was 7.4 months, with the 1-, 2-year recurrence-free survival rates as 35.0%, 26.3%. There was a significant difference in recurrence-free survival between the 48 patients with non-pathologic complete response in the adjuvant therapy group and the 23 patients with non-pathologic complete response in the follow-up monitoring group ( χ2=5.241, P<0.05). Conclusion:For HCC patients with conversion therapy of TKIs and ICIs followed by sequential hepatectomy, postoperative adjuvant therapy, compared to postoperative follow-up monitoring, can prolong the recurrence-free survival time of patients, of whom cases with non-pathologic complete response can benefit from adjuvant therapy.

To investigate the clinical value of endoscopic ultrasound-guided puncture drainage in the treatment for liver abscess and abdominal and pelvic abscess with difficulty in conventional puncture drainage. Data of 12 such patients in the Second Affiliated Hospital of Soochow University from January 2015 to November 2023 were retrospectivly analyzed. Results showed liver abscess in 4 cases, abdominal and pelvic abscess in 8 cases. All patients had fever with varying degrees of abdominal pain. Twelve patients with liver abscess and abdominal and pelvic abscess received 13 times of endoscopic ultrasound-guided puncture (1 patient with a large abdominal and pelvic cyst complicated with infection received transgastric and transrectal puncture of 2 times). The puncture needle was successfully penetrated into the pus cavity. Four patients with liver abscess underwent endoscopic ultrasound-guided suction and irrigation, and the abscess was almost completely aspirated. Seven patients with abdominal and pelvic abscess underwent endoscopic ultrasound-guided suction and irrigation, of which 5 cases were almost completely aspirated, and 2 cases had poor drainage effect due to the viscous pus (1 case returned to normal temperature after anti-infection treatment; 1 case had recurrent fever after the operation, and septic shock and death occurred 2 weeks after the operation). A patient with recurrent abdominal and pelvic sclerosis after the operation had multiple abscesses in the abdomen and pelvis, and percutaneous CT-guided drainage was performed for abdominal abscess, but the fever was still repeated. Endoscopic ultrasound-guided balloon dilation plus double pig tail and nasobiliary duct drainage were performed. The patient's temperature returned to normal and abdominal pain was relieved 48 hours after the operation. The total effective rate of abscess drainage was 83.3% (10/12), and the effective rate of suction combined with irrigation for abscess drainage was 81.8% (9/11), and no operation-related complications were observed in all patients. After 3 months of follow-up, no recurrence occurred in 10 patients with effective drainage of abscess, and abscess was self-absorbed in 1 patient with pelvic abscess without effective drainage and no recurrence was observed. Endoscopic ultrasound-guided puncture drainage is of certain clinical value for some liver abscesses and abdominal and pelvic abscesses that are difficult to be drained by conventional puncture, and can reduce the secondary trauma caused by surgical operations.
