Objective: To explore the latent profile characteristics of regulatory emotional self-efficacy and its relationship with non-suicidal self-injurious (NSSI) behavior among junior and senior high school students, so as to provide a basis for effectively reducing NSSI behaviors. Methods: From April to October 2023, a total of 1 217 junior and senior high school students were selected from Tongren City, Zunyi City and Qiannan Prefecture of Guizhou Province by stratified cluster random sampling method. The Scale of Regulatory Emotional Self-efficacy and the Adolescent Self-injury Scale were administered. Latent profile analysis (LPA) was employed to explore distinct profiles of regulatory emotional self-efficacy, and the Lanza, Tan, and Bray s method (LTB) was used to analyze the relationship between these profiles and NSSI behavior. Results: The prevalence rate of NSSI behavior among junior and senior high school students was 28.6%. Among males, regulatory emotional self-efficacy was categorized into two types: moderate positive expression-low negative management group (59.1%, n =353) and high efficacy group (40.9%, n =244); among females, regulatory emotional self-efficacy was classified into three categories: low efficacy group (18.4%, n =114), high positive expression-low negative management group (56.3%, n =349), and high efficacy group (25.3%, n =157). There were statistically significant differences in total NSSI scores across different potential categories of regulatory emotional self-efficacy within both males and females ( Z/H = -5.75 , 57.58, both P <0.01). The differences in NSSI prevalence rates across the potential categories of regulatory emotional self-efficacy were statistically significant for both males and females ( χ 2=38.00, 69.14, both P <0.01), and among females, the differences in NSSI prevalence rates between the high efficacy group and the low efficacy group ( χ 2=60.01) and between the high efficacy group and the high positive expression-low negative management group ( χ 2=31.34) were also statistically significant (both P < 0.016 7 ). Binary Logistic regression analysis revealed that, compared with the high efficacy group within each gender, the moderate positive expression-low negative management group among males ( OR =2.36), and both the low efficacy group and the high positive expression-low negative management group among females ( OR =6.19, 2.97), were at an increased risk of engaging in NSSI (all P <0.01). Conclusion Different latent profiles of regulatory emotional self efficacy among junior and senior high school students are associated with NSSI behavior.

Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

Objective To evaluate the cost-effectiveness of the combination therapy of ribociclib plus fulvestrant compared to fulvestrant monotherapy as a second-line treatment for postmenopausal patients with hormone receptor-positive(HR+)/human epidermal growth factor receptor 2-negative(HER2-)advanced metastatic breast cancer from the perspective of the Chinese healthcare system.Methods A partitioned survival model was constructed based on MONALEESA-3 study data,with the model cycle of 4 weeks and the time range of 15 years.Total cost,quality-adjusted life years(QALYs)and incremental cost-effectiveness ratio(ICER)were compared between ribociclib combined with fulvestrant and fulvestrant monotherapy as a second-line treatment for postmenopausal patients with HR+/HER2-advanced metastatic breast cancer.The robustness of the models was validated through one-way sensitivity analysis and probabilistic sensitivity analysis.Results Compared with the fulvestrant monotherapy regimen,the ICER for the ribociclib combined with fulvestrant regimen was 187,958.06 yuan/QALY,which was below the willingness-to-pay(WTP)threshold of three times China's per capita gross domestic product(GDP)in 2024(287,247 yuan/QALY).The one-way sensitivity analysis revealed that the ICER was primarily influenced by the proportion of patients receiving subsequent treatments with the combination therapy or fulvestrant monotherapy,and the utility value of progression-free survival.The probabilistic sensitivity analysis showed that at a WTP threshold of three times China's per capita GDP in China in 2024(287,247 yuan/QALY),the probability of the ribociclib combination therapy being cost-effective was 100%.Conclusion In the context of the Chinese healthcare system,the combination therapy of ribociclib and fulvestrant is more cost-effective than fulvestrant monotherapy for the second-line treatment of postmenopausal patients with HR+/HER2-advanced metastatic breast cancer.

Objective:To evaluate the effect of value orientation brief therapy(VBT)combined with selective serotonin reuptake inhibitors(SSRIs)on clinical symptoms,rumination,decision-making ability,and cognitive func-tion in patients with mild to moderate depression.Methods:Eighty patients meeting the DSM-5 diagnostic criteria for mild to moderate depression were randomly assigned to either a medication(SSRIs)group(36 completed)or a VBT combined group(38 completed)for a 6-week intervention.Baseline and post-intervention assessments includ-ed the Hamilton Depression Scale(HAMD),Hamilton Anxious Scale(HAMA),Ruminative Response Scale-Chi-nese Version(RRS-CV),Iowa Gambling Test(IGT),number of eye fixation(NEF),responsive search score(RSS)in exploratory eye trajectory movement were used to evaluate patients'anxiety and depression symptoms,ru-minative thinking,decision-making function,and cognitive function.Results:The VBT combined group showed sig-nificantly better therapeutic effects than the medication group(P＜0.05).Compared to baseline and the medication group,the VBT combined group had significantly lower post-intervention scores in HAMD,HAMA,symptom rumi-nation,introspective reflection,compulsive meditation,and RRS-CV total scores after intervention(Ps＜0.05),and significantly higher scores in IGT net profit scores,NEF,and RSS scores(Ps＜0.05).Compared with the medica-tion group,the VBT combined group demonstrated a greater reduction in HAMD,HAMA,symptom rumination,in-trospective reflection,compulsive meditation,and RRS-CV total scores before and after intervention(Ps＜0.05),and a larger increase in IGT net profit scores,NEF,and RSS scores(Ps＜0.05).Conclusion:VBT combined with SSRIs effectively improves the symptoms of depression,anxiety,decision-making ability,rumination thinking,and cognitive function in patients with mild to moderate depression.

Binge eating disorder(BED)is a common eating disorder whose pathogenesis involves both neurobiological and psychological mechanisms.At the neurobiological level,the development of BED is associated with abnormal resting-state brain functional connectivity in the reward circuitry,dysregulation of the endocannabinoid system,and elevated leptin levels.This paper reveals that the neurobiological mechanisms of BED may influence psychological processes,including habitual behavioral imbalances and impaired emotion regulation.Conversely,the dysfunction of behavior in the psychological domain may further modulate neurobiological manifestations.This finding provides insights for future research aimed at systematically integrating neural mechanisms into clinical interventions,ultimately facilitating treatment advancement and prognostic improvement.

Objective To analyze the changes in serum miR-205,miR-23b and miR-25 levels and their correlation with the prognosis of patients with different severities of sepsis.Methods A retrospective study was conducted in 86 patients with sepsis admitted to our hospital between September 2021 and September 2023.Based on the severity of illness,patients were divided into mild(52 cases)and severe(34 cases)groups.Eighty healthy individuals undergoing medical check-ups during the same period were selected as controls.The patients were follo wed-up for 28 days and were then categorized into a survival group(68 patients)and a death group(18 patients).Real-time polymerase chain reaction was used to detect the serum miR-205,miR-23b,and miR-25 levels in patients and analyze their corre-lation with prognosis.Multivariate Cox regression analysis was used to analyze the risk factors affecting patient prognosis.The diagnostic value of serum miR-205,miR-23b,and miR-25 levels in assessing sepsis and their predictive value for prognosis were analyzed using receiver operating characteristic curves.Results Serum miR-205,miR-23b,and miR-25 levels were significantly lower in the two groups of patients with sepsis than in the control group(P＜0.05),and were significantly higher in the survival group than in the death group(P＜0.05).Their levels negatively correlated with prognosis.Heart rate and APACHE Ⅱ score were risk factors for a poor prognosis of patients with sepsis,whereas high serum miR-205,miR-23b,and miR-25 levels were protective factors(P＜0.05).The areas under the curve(AUC)for individual serum miR-205,miR-23b,and miR-25 levels and their combination to assess sepsis were 0.794,0.786,0.768,and 0.926,respectively.The AUC for predicting poor prognosis for patients were 0.776,0.762,0.797,and 0.918,respectively.Conclusion Serum miR-205,miR-23b,and miR-25 levels were reduced in patients with sepsis,and were closely correlated with patient prognosis.Thus,they may serve as serological biomarkers for assessing disease and predicting prognosis.

Objective:To explore the effects of different titanium(Ti)surfaces on mitochondria metabolism and polarization of mac-rophages.Methods:The anodic oxidation method prepared nanotubes with distinct morphologies(NT5 and NT20 groups)on smooth titanium surfaces(P group)were characterized by scanning electron microscopy(SEM).After 24 hours of culturing RAW264.7 cells on the samples,SEM was employed to observe the morphology of the cells of all groups.Levels of mitochondria ATP and ROS,as well as the activity of hexokinase(HK),were measured by fluorescence probes and luciferase assays.The expression of iNOS,Arg-1,TNF-α and CD206 mRNA was evaluated by RT-qPCR.Changes in mitochondria metabolism and macrophage polarization were studied following inhibition of cellular glycolysis by using 2-deoxy-D-glucose(2-DG)in groups P*and NT20*.Results:Compared with the P group,the NT5 group showed no significant changes in mitochondria ATP,ROS levels and HK activity,but an upregula-tion in M2-associated gene expression was observed.In the NT20 group,mitochondria ATP and ROS levels were increased,HK ac-tivity was elevated,and M1-associated gene expression was upregulated.After glycolysis inhibition,there was no significant differ-ence in mitochondria ATP,ROS levels,HK activity and polarization-related gene expression levels between the P*and NT20*groups compared with the P group.Conclusion:Large-diameter nanotubes may promote macrophage M1 polarization by regulating the metabolic reprogramming that occurs in macrophage mitochondria.
