Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Objective: To explore the relationship between sleep characteristics, physical activity patterns, with depressive and anxiety symptoms in college students, so as to provide reference for student mental health promotion. Methods: From September to November 2023, a convenience sampling method was used to select 7 954 college students aged 18-22 years from 9 universities in Shanghai, Hubei, and Jiangxi. Assessments were conducted using the International Physical Activity Questionnaire Short-Form (IPAQ-SF), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and Pittsburgh Sleep Quality Index (PSQI) to evaluate physical activity, depressive and anxiety symptoms, and sleep quality, respectively. Logistic regression analysis was employed to explore the impact of sleep characteristics and physical activity patterns on depressive and anxiety symptoms and their comorbidity among college students. Results: The detection rates for depressive symptoms, anxiety symptoms, and comorbid depression and anxiety symptoms were 25.67%, 35.39%, and 23.15%, respectively. Factors such as gender, grade, household registration, parental education level, annual family income, family structure, and dietary habits were all associated with the detection rates of depressive and anxiety symptoms and their comorbidity (χ2=4.41-118.39, P<0.05). Physical activity patterns, sleep duration, sleep quality, and sleepwake characteristics were also associated with the occurrence of depressive and anxiety symptoms and their comorbidity (χ2=9.66-627.70, P<0.05). Logistic regression analysis showed that college students who stayed up late and slept less than 7 had the highest risk of depressive and anxiety symptoms and their comorbidity (OR=1.93, 1.85, 1.88, P<0.05). Compared to regular physical activity patterns, insufficient physical activity patterns were associated with an increased risk of depressive and anxiety symptoms (all OR=1.18, P<0.05). Further stratified analysis results showed that the risk of depression, anxiety and their comorbidity increased in college students who stayed up late and slept less than 7 h, went to bed before midnight and slept less than 7 h, or went to bed before midnight and slept more than 7 h but did not have sufficient physical activity (P<0.05). Conclusions Sleep characteristics and physical activity patterns significantly affect depressive and anxiety symptoms in college students. Universities should strengthen sleep management and implement flexible physical activity interventions to help students establish healthy lifestyles.

Alzheimer's disease (AD) is a common neurodegenerative disorder among the elderly, and BuChE has emerged as a potential therapeutic target. In this study, we reported the development of compound 8e, a selective reversible BuChE inhibitor (eqBuChE IC₅₀ = 0.049 μmol/L, huBuChE IC₅₀ = 0.066 μmol/L), identified through extensive virtual screening and lead optimization. Compound 8e demonstrated favorable blood-brain barrier permeability, good drug-likeness property and pronounced neuroprotective efficacy. Additionally, 8e exhibited significant therapeutic effects in zebrafish AD models and scopolamine-induced cognitive impairments in mice. Further, 8e significantly improved cognitive function in APP/PS1 transgenic mice. Proteomics analysis demonstrated that 8e markedly elevated the expression levels of very low-density lipoprotein receptor (VLDLR), offering valuable insights into its potential modulation of the Reelin-mediated signaling pathway. Thus, compound 8e emerges as a novel and potent BuChE inhibitor for the treatment of AD, with significant implications for further exploration into its mechanisms of action and therapeutic applications.

The standardized workflow of computer-aided static guided implant surgery includes preoperative exami-nation,data acquisition,guide design,guide fabrication and surgery.Errors may occur at each step,leading to irrevers-ible cumulative effects and thus impacting the accuracy of implant placement.However,clinicians tend to focus on fac-tors causing errors in surgical operations,ignoring the possibility of irreversible errors in nonstandard guided surgery.Based on the clinical practice of domestic experts and research progress at home and abroad,this paper summarizes the sources of errors in guided implant surgery from the perspectives of preoperative inspection,data collection,guide de-signing and manufacturing and describes strategies to resolve errors so as to gain expert consensus.Consensus recom-mendation:1.Preoperative considerations:the appropriate implant guide type should be selected according to the pa-tient's oral condition before surgery,and a retaining screw-assisted support guide should be selected if necessary.2.Da-ta acquisition should be standardized as much as possible,including beam CT and extraoral scanning.CBCT performed with the patient's head fixed and with a small field of view is recommended.For patients with metal prostheses inside the mouth,a registration marker guide should be used,and the ambient temperature and light of the external oral scan-ner should be reasonably controlled.3.Optimization of computer-aided design:it is recommended to select a handle-guided planting system and a closed metal sleeve and to register images by overlapping markers.Properly designing the retaining screws,extending the support structure of the guide plate and increasing the length of the guide section are methods to feasibly reduce the incidence of surgical errors.4.Improving computer-aided production:it is also crucial to set the best printing parameters according to different printing technologies and to choose the most appropriate postpro-cessing procedures.

Bone substitute material implantation has become an important treatment strategy for the repair of oral and maxillofacial bone defects. Recent studies have shown that appropriate inflammatory and immune cells are essential factors in the process of osteoinduction of bone substitute materials. Previous studies have mainly focused on innate immune cells such as macrophages. In our previous work, we found that T lymphocytes, as adaptive immune cells, are also essential in the osteoinduction procedure. As the most important antigen-presenting cell, whether dendritic cells (DCs) can recognize non-antigen biomaterials and participate in osteoinduction was still unclear. In this study, we found that surgical trauma associated with materials implantation induces necrocytosis, and this causes the release of high mobility group protein-1 (HMGB1), which is adsorbed on the surface of bone substitute materials. Subsequently, HMGB1-adsorbed materials were recognized by the TLR4-MYD88-NFκB signal axis of dendritic cells, and the inflammatory response was activated. Finally, activated DCs release regeneration-related chemokines, recruit mesenchymal stem cells, and initiate the osteoinduction process. This study sheds light on the immune-regeneration process after bone substitute materials implantation, points out a potential direction for the development of bone substitute materials, and provides guidance for the development of clinical surgical methods.

OBJECTIVE: To analyze the clinical features and pathogenic variant in a Chinese pedigree affected with cleidocranial dysplasia (CCD). METHODS: Clinical data of 8 patients from the pedigree was collected, including physical examination and X-ray images of head, face, spine, limbs, and mouth. Peripheral blood samples were collected from 6 affected members for the extraction of genomic DNA. The proband and other 3 patients were subjected to trio-whole exome sequencing. Candidate variant was verified by Sanger sequencing of the other 2 affected members from the pedigree. RESULTS: This pedigree has included 22 members (8 affected) from four generations. Genetic testing revealed that the proband has harbored a novel pathogenic variant of the RUNX2 gene [NM_001024630: c.1268_1277del (p.P425Afs*56)], which was inherited from her mother and carried by all affected members in the pedigree. The same variant was not detected among the unaffected members, suggesting co-segregation with the phenotype. CONCLUSION The c.1268_1277del (p.P425Afs*56) variant of the RUNX2 gene probably underlay the pathogenesis of CCD in this pedigree. Genetic testing has facilitated the definite diagnosis and enabled prenatal diagnosis.

Objective:To investigate the application of 3D printing technique in percutaneous nephrolithotomy (PCNL) of patients with complicated kidney stones.Methods:From January 2015 to December 2017, 60 patients with complicated kidney stones were enrolled in the First Affiliated Hospital of Hebei North University for prospective study, and PCNL was proposed.All the patients were randomly divided into 3D print group (30 cases) and conventional image inspection group (30 cases, control group). Before operation, CT urography (CTU) was used in both groups.In 3D printing group, digital imaging and communications in medicine (DICOM) files of CT were extracted for 3D image postprocessing, and thermoplastic materials were used to print 3D model.In the 3D printing group, the digital imaging and communications in medicine (DICOM) files of CT were extracted for 3D image post-processing, and the 3D model was printed with thermoplastic materials.According to the comprehensive planning of 3D kidney model, a virtual safe and reliable percutaneous renal access was established for each patient, and PCNL was executed.The patients in the two groups were compared before, during and after operation.Preoperative: age, sex, body mass index, blood creatinine, stone size and CT value.During the operation: (1) the target renal calices location time; (2) the conformity between the preoperative planning and the actual operation; (3) the operation completion time.After operation: (1) stone removal rate; (2) hemoglobin reduction level; (3) postoperative recovery.Results:All the 60 patients successfully completed the operation, 30 patients successfully printed out the 3D model, which can accurately express the relationship between the stone and the adjacent anatomical structure, the internal renal artery and the collecting system.Positioning time of 3D printing group in target renal calices((2.9 ± 1.5) min vs.(5.8 ± 1.7) min, P=0.023), coincidence between simulated and actual puncture calices((89.5 ± 3.5)% vs.(60.2 ± 5.7)%, P=0.005), postoperative stone removal rate ((89.9 ± 4.5)% vs.(75.9 ± 5.2)%, P=0.009), and hemoglobin levels((1.4 ± 0.5) g/L vs.(2.9 ± 1.4) g/L, P=0.032) were superior to the control group, and the difference was statistically significant.But there was no significant difference between the two groups (all P>0.05). Conclusion:The 3D printed kidney model truly restores the anatomical details around the kidneys and stones, providing a stereoscopic and intuitive way to perform surgery, so it maybe has a significance guidance for percutaneous nephrolithotomy.

Objective: To explore the impact of socioeconomic status on minority college students’ healthy sports behaviors, and to provide guidance for improving physical fitness among minority college students. Methods: Binary Logistic regression and path analysis were used to analyze the path and effect of socioeconomic status on minority college students’ healthy sports behaviors, controlled for health status, academic pressure, sports attitude, sports venues, sports skills and health knowledge. Results: Socioeconomic status was positively associated with students’ healthy sports behaviors (OR>1). With the potential variables controlled, the odds of participating in healthy sports activity among urban students, sophomores and female students was 2.10, 2.60 and 0.59 times higher than that of rural students, freshman and male students. Path analysis showed that the direct effect of socio-economic status on minority college students’ healthy sports behavior was 0.07, the indirect effect was 0.16, and the total effect was 0.23. Conclusion Socioeconomic status shows direct and indirect effect on healthy sports behaviors among college students, with the indirect effect being larger than direct effect. Apart from socioeconomic status, physical fitness education, as well as creating and maintaining a good physical exercise environment by schools and society should be encouraged to facilitate college students establishing healthy sports behaviors.

Objective To observe the clinical efficacy of radiofrequency ablation for treatment of discogenic lumbar spinal nerve posterior branch neuralgia after vertebral column endoscope operation. Methods Thirty-six patients with discogenic lumbar spinal nerve posterior branch neuralgia after vertebral column endoscope surgery admitted to the Affiliated Hospital of Logistics University of People's Armed Police from December 2011 to December 2017 were enrolled. According to difference in therapeutic methods, they were randomly divided into two groups, 18 cases in each group. The radiofrequency ablation group was treated with X-ray imaging guided lumbar spinal nerve posterior branch radiofrequency thermo-coagulation; the drug group received oral diclofenac sodium conservative treatment, 75 mg twice daily for 3 weeks. Both groups were followed up for 6 months, visual analogue scores (VAS) were used to evaluate the pain before and after treatment, the Oswestry dysfunction index was used to assess the degree of lumbar function recovery, and the surgical complications and adverse drug reactions were observed. Results The VAS scores in the two groups were similar before treatment; after treatment for 1 month, the VAS scores in both groups were significantly lower than those before treatment (radiofrequency ablation group: 1.83±0.71 vs. 5.67±0.77; drug group: 2.22±0.43 vs. 5.28±0.67, both P < 0.05); after treatment for 3 months and 6 months, the VAS scores were increased gradually, however, the scores of radiofrequency ablation group were significantly lower than those in the drug group (3 months was 2.00±0.59 vs. 3.39±0.70, 6 months was 2.17±0.51 vs. 3.61±0.50, both P < 0.05), moreover, the excellent and good rates of postoperative pain efficacy and of Oswestry dysfunction index improvement in the radiofrequency ablation group were significantly higher than those in the drug group [excellent and good rates of postoperative pain efficacy: 94.44% (17/18) vs. 22.22% (4/18), excellent and good rates of Oswestry dysfunction index improvement: 77.78% (14/18) vs. 44.44% (8/18), both P < 0.05]. There were no complications of infection and spinal nerve anterior branch injury in the radiofrequency ablation group, and 6 patients in the drug group presented mild gastric discomfort, which was relieved after symptomatic treatment. Conclusion The radiofrequency ablation is an effective method for treatment of discogenic lumbar neuralgia after vertebral column operation, compared with the conservative therapy, the ablation is more effective to relieve pain for a long time, promote the recovery of neural function, and the operation is safe with very few adverse reactions.
