Oral squamous cell carcinoma (OSCC), the most common type of head and neck malignancy, has a poor prognosis owing to its high invasiveness and high rate of cervical lymph node metastasis. The tumor microenvironment (TME) is a complex microenvironment that is essential for tumor cell survival. Tumor-associated immune cell (TAIC), the main stromal cell of TME, regulates the proliferation, invasion, epithelial-mesenchymal transformation (EMT), and anti-tumor immunity of OSCC. M2-tumor-associated macrophages (TAMs) promote the invasion and metastasis of OSCC through the macrophage migration inhibitory factor/NOD-like receptor family pyrin domain containing 3/interleukin (IL)-1β axis, while N2-tumor-associated neutrophils (TANs) regulate the proliferation and EMT of OSCC through the Janus kinase 2/signal transducer and activator of transcription 3 pathway. Meanwhile, myeloid-derived suppressor cells (MDSCs) accelerate the progression of OSCC by secreting IL-6, IL-10, and transforming growth factor (TGF)-β; T cells promote inflammation by secreting IL-17 and inhibit inflammation-mediated tumor immune response by secreting IL-10 and TGF-β; and natural killer (NK) cells recognize and attack OSCC cells to inhibit OSCC progression. TAIC interaction network also regulates OSCC progression. M2-TAMs regulate the invasion and metastasis of OSCC by promoting T cell apoptosis through the secretion of IL-10 and programmed death-ligand (PD-L) -1, while N2-TANs inhibit T cell proliferation and cytotoxicity by secreting LOX-1 and arginase-1. MDSCs inhibit the proliferation and anti-tumor effects of CD8+ T cells through the inactivation of programmed cell death (PD)-1/PD-L1 signaling. Additionally, MDSCs inhibit the proliferation of T cells by decreasing the expression of the CD3-zeta chain and interferon-γ (IFN-γ). Moreover, tumor-infiltrating lymphocytes and NK cells were found to be positively correlated in OSCC progression. Therefore, target regulation, related signaling pathways, and the interaction network of TAIC may serve as promising therapeutic targets in the immunotherapy of OSCC. In this review, we summarize the recent research on the effects of TAIC and their interaction network in the TME in the progression of OSCC and explore its application in the early diagnosis and treatment of OSCC

BackgroundSevere mental disorders represent a major public health concern due to the high disability rates and substantial disease burden, which has garnered significant national attention and prompted their inclusion in public health project management systems. However, credible evidence regarding the current status of disease management and factors influencing disease stabilization among patients with severe mental disorders in Luzhou City, Sichuan Province, remains limited. ObjectiveTo investigate the current management status of patients with severe mental disorders in Luzhou City, Sichuan Province, and to analyze influencing factors of disease stabilization among patients under standardized care, so as to provide evidence-based insights for developing targeted management strategies to optimize clinical interventions for this patient population. MethodsIn March 2023, data were extracted from the Sichuan Mental Health Service Comprehensive Management Platform for patients with severe mental disorders in Luzhou City who received management between December 2017 and December 2022. Information on mental health service utilization and clinical status changes was collected. Trend analysis was conducted to evaluate temporal changes in key management indicators for severe mental disorders in Luzhou City. Logistic regression analysis was employed to identify factors influencing the disease stabilization or fluctuation of these patients. ResultsThis study enrolled a total of 20 232 patients. In Luzhou City, the stabilization rate and standardized management rate of severe mental disorders were 94.89% and 79.36% in 2017, respectively, which increased to 95.33% and 96.92% by 2022. The regular medication adherence rate rose from 34.42% in 2018 to 86.81% in 2022. In 2022, the regular medication adherence rate was 71.80% for schizophrenia, 55.26% for paranoid psychosis, and 51.43% for schizoaffective disorder. Multivariate analysis identified the following protective factors for disease stabilization: age of 18~39 years (OR=0.613, 95% CI: 0.409~0.918), age of 40~65 years (OR=0.615, 95% CI: 0.407~0.931), urban residence (OR=0.587, 95% CI: 0.478~0.720), and regular medication adherence (OR=0.826, 95% CI: 0.702~0.973). Risk factors for disease fluctuation included poor (OR=1.712, 95% CI: 1.436~2.040), non-inclusion in care-support programs (OR=1.928, 95% CI: 1.694~2.193), non-participation in community rehabilitation (OR=2.255, 95% CI: 1.930~2.634), and intermittent medication adherence (OR=3.893, 95% CI: 2.548~5.946). ConclusionThe stability rate, standardized management rate, and regular medication adherence rate of patients with severe mental disorders in Luzhou City have shown a year-by-year increase. Age, household registration status, economic condition, medication compliance, and community-based rehabilitation were identified as influencing factors for disease fluctuation in these patients.

BackgroundStudents in secondary vocational health school are at the age of puberty and prone to depressive symptoms. Peer victimization and social media addiction are found to be crucial in influencing the development of depression, and positive mental health has been proven to alleviate depressive symptoms, whereas there remains a striking lack of research on the mediating role of positive mental health and social media addiction in the relationship between peer victimization and depressive symptoms among secondary vocational health school students. ObjectiveTo explore the relationship between peer victimization and depressive symptoms and investigate the mediating role of positive mental health and social media addiction, so as to provide references for the prevention of depression among secondary vocational health school students. MethodsFrom October to December 2020, a cluster sampling framework was utilized to recruit 7 307 students from a secondary vocational health school in Luzhou City, Sichuan Province. Assessments were performed using Multidimensional Peer Victimization Scale (MPVS), Warwick-Edinburgh Mental Well-being Scale (WEMWBS), Bergen Social Media Addiction Scale (BSMAS) and Patient Health Questionnaire Depression Scale-9 item (PHQ-9). Spearman correlation analysis was calculated to determine correlations between scores of scales, Process 4.0 was employed to test the mediation effect, and the bias-corrected Bootstrap procedure was used to test the significance of the mediation effect. ResultsA total of 7 044 (96.40%) valid questionnaires were collected. And 4 391(62.34%)students were found to have depressive symptoms. Correlation analysis revealed that PHQ-9 score was positively correlated with BSMAS score and MPVS score (r=0.404, 0.506, P<0.01). WEMWBS score was negatively correlated with PHQ-9 score, BSMAS score and MPVS score (r=-0.587, -0.259, -0.358, P<0.01). BSMAS score was positively correlated with MPVS score (r=0.328, P<0.01). Positive mental health played a mediating role in the relationship between peer victimization and depressive symptoms, with an indirect effect value of 0.130 (95% CI: 0.119~0.141), accounting for 30.81% of the total effect. Social media addiction also mediated the relationship between peer victimization and depressive symptoms, with an indirect effect value of 0.052 (95% CI: 0.045~0.059), accounting for 12.34% of the total effect. Positive mental health and social media addiction exhibited a chained mediation effect on the relationship between peer victimization and depressive symptoms, with an indirect effect value of 0.012 (95% CI: 0.010~0.014) and accounting for 2.84% of the total effect. ConclusionPeer victimization can affect the presence of depressive symptoms among secondary vocational health school students both directly and indirectly through either separate or chained mediation of positive mental health and social media addiction.
6.Research progress on the role of zinc finger proteins in the development of oral cancer
Journal of Prevention and Treatment for Stomatological Diseases 2025;33(5):425-432
Oral cancer is one of the most common malignancies in the head and neck regions. few patients benefit from current clinical therapy. Zinc finger proteins (ZNFs) are one of the largest transcription factor family proteins in the human genome. ZNFs bind to DNA, RNA, and proteins through their unique three-dimensional structure created by zinc ions to regulate gene transcription, RNA packaging, and protein folding. In recent years, the number of studies focused on the functional mechanism of ZNFs in regulating the progression of oral cancer has been increasing, with focuses on: ① ZNF677, ZNF460, ZNF154, ZNF132, ZNF281, Kaiso, and ZNF582, which regulate the invasion and metastasis of tumor cells; ② ZNF750 and PEST-containing nuclear protein (PCNP), which regulate the cell cycle; ③ ZNFs, which are involved in forming the tumor immune microenvironment, such as ZNF71 and myeloid zinc finger 1 (MZF1). For example, methylation modification modulates the reduction of ZNF677 in oral cancer and reduces the proliferation, migration, and invasion of oral cancer cells by inhibiting the protein kinase B/forkhead box O3a (AKT/FOXO3a) pathway; and ZNF460 promotes the proliferation, migration, and invasion of oral cancer cells by regulating microRNA-320a/alpha thalassemia/mental retardation, X-linked (ATRX) axis. In addition, ZNF750 inhibits the growth and metastasis of oral cancer by suppressing cell cycle transcription factor activity. Further, ZNF71 promotes the progression of oral cancer by reducing the infiltration of tumor immune cells. In this review, we will summarize the molecular mechanism, regulatory meshwork, and pro-tumor and anti-tumor roles of ZNFs in the pathogenesis of oral cancer. Our study may provide a new strategy for the diagnosis and treatment of oral cancer.

Objective:
Based on spinopelvic parameters and biomechanical principles, the pedicle-facet joint (PFJ) morphological characteristics of isthmic and degenerative spondylolisthesis were analyzed, and the mechanism of their onset and progression was discussed.
Methods:
This retrospective cross-sectional study included 194 patients with L5 spondylolysis or L5–S1 low-grade isthmic spondylolisthesis (IS group), 172 patients with L4–5 degenerative spondylolisthesis (DS group), and 366 patients with nonlumbar spondylolysis (NL group). The spinopelvic parameters and PFJ morphological parameters of the patients were measured, the differences in these parameters among and within the 3 groups were compared, and the correlations were analyzed.
Results:
Sacral slope (SS) and lumbar lordosis (LL) were the highest in the IS group, the second highest in the DS group, and the lowest in the NL group. Among the 3 groups, the L4 facet joint angle (FJA) was the largest in the IS group, the second largest in the NL group, and the smallest in the DS group. The L4 pedicle-facet joint angle (PFA) was the largest in the DS group, the second largest in the IS group, and the smallest in the NL group. Pearson correlation analysis showed that within each group, SS and LL were negatively correlated with FJA and positively correlated with PFA.
Conclusion
This study found a correlation between the PFJ morphological characteristics of patients with lumbar spondylolisthesis and spinopelvic parameters, suggesting that the morphological characteristics of PFJs may be caused by varying stresses under different spinopelvic morphologies.
