Background/Aims: Transmembrane 4 L six family member 1 (TM4SF1) is highly expressed and contributes to the progression of various malignancies. However, how it modulates hepatocellular carcinoma (HCC) progression and senescence remains to be elucidated. Methods: TM4SF1 expression in HCC samples was evaluated using immunohistochemistry and flow cytometry. Cellular senescence was assessed through SA-β-gal activity assays and Western blot analysis. TM4SF1-related protein interactions were investigated using immunoprecipitation-mass spectrometry, co-immunoprecipitation, bimolecular fluorescence complementation, and immunofluorescence. Tumor-infiltrating immune cells were analyzed by flow cytometry. The HCC mouse model was established via hydrodynamic tail vein injection. Results: TM4SF1 was highly expressed in human HCC samples and murine models. Knockdown of TM4SF1 suppressed HCC proliferation both in vitro and in vivo, inducing non-secretory senescence through upregulation of p16 and p21. TM4SF1 enhanced the interaction between AKT1 and PDPK1, thereby promoting AKT phosphorylation, which subsequently downregulated p16 and p21. Meanwhile, TM4SF1-mediated AKT phosphorylation enhanced PD-L1 expression while reducing major histocompatibility complex class I level on tumor cells, leading to impaired cytotoxic function of CD8+ T cells and an increased proportion of exhausted CD8+ T cells. In clinical HCC samples, elevated TM4SF1 expression was associated with resistance to anti-PD-1 immunotherapy. Targeting TM4SF1 via adeno-associated virus induced tumor senescence, reduced tumor burden and synergistically enhanced the efficacy of anti-PD-1 therapy. Conclusions Our results revealed that TM4SF1 regulated tumor cell senescence and immune evasion through the AKT pathway, highlighting its potential as a therapeutic target in HCC, particularly in combination with first-line immunotherapy.

Pleomorphic adenoma arising from the torus tubarius of the nasopharynx is an extremely rare entity with limited epidemiological data and unclear etiological mechanisms. Its pathogenesis may be related to the eustachian tube salivary glands. Here we report an elderly female patient with a long history of snoring, hypernasal speech and epistaxis. Following comprehensive diagnostic evaluation, the patient underwent tumor resection under nasal endoscopy. There were no postoperative complications, the symptoms were significantly improved, and there was no obvious recurrence during the follow-up. We summarized the experience of diagnosis and treatment of giant pleomorphic adenoma of the tubal torus. The main treatment for tubal torus pleomorphic adenoma is complete surgical resection, with a good prognosis and a low recurrence rate.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the effectiveness of patient participation and Internet plus in fall prevention management strategies of elderly inpatients and analyze the causes of falls, so as to provide a basis for continuous improvement in fall prevention to investigate their continuous improvement.Methods:A pre- and post-control study was conducted. Totally 8 480 elderly inpatients hospitalized in the Department of Internal Medicine from 1 June 2020 to 31 May 2021 in Chenzhou NO. 1 People′s Hospital were selected by convenient sampling as the control group, and 8 662 elderly inpatients hospitalized in the Department of Internal Medicine from 1 June 2021 to 31 May 2022 were in the experimental group. The routine fall prevention measures were used in the control group, and on this basis, the experimental group formulated and implemented fall prevention management strategies involving patients based on the patient participation framework "informing, participating, empowering, cooperating, and electronic information support" and introduced Internet plus. Then the differences between the two groups in terms of the incidence of falls and the satisfaction rate of nursing care were compared.Results:The experimental group included 8 662 cases (5 110 males and 3 552 females) with (73.96 ± 8.78) years old, while the control group included 8 480 cases (4 918 males and 3 562 females) with (74.11 ± 8.59) years old. The incidence of falls in experimental group (0.092%, 8/8 662) was lower than that in control group (0.224%, 19/8 480), and the difference was statistically significant ( χ 2=4.71, P<0.05); the nursing care satisfaction rate of experimental group (98.880%, 8 565/8 662) was higher than that of control group (96.450%, 8 179/8 480), and the difference also was statistically significant ( χ 2=106.50, P<0.01); the analysis of the fall causes of the patients revealed that the toilet squatting commode was an important hidden risk of falls in elderly patients. Conclusions:Fall prevention management strategies based on patient participation can reduce the incidence of falls in elderly patients and improve the satisfaction rate of nursing care. Patient participation introduced "Internet plus" can prevent patient falls. The root causes of patient falls will continue to change, and care managers should continually track real-time changes in the root causes of falls to identify problems, develop and adjust prevention strategies accordingly, and pay attention to the importance of infrastructure in the safety of older patients.

Objective:To investigate the effects and possible mechanisms of caffeic acid phenethyl ester (CAPE) on the replication, amplification, and fibre formation of prions (PrP Sc). Methods:The CCK8 assay was used to detect the cell viability of the prion-infected cell model SMB-S15 after CAPE treatment for 3 days and 7 days and the maximum safe concentration of CAPE for SMB-S15 was obtained. The cells were treated with a concentration within a safe range, and the content of PrP Sc in the cells before and after CAPE treatment was analyzed by western blot. Protein misfolding cycle amplification (PMCA) and western blot were used to assess changes in PrP Sc level in amplification products following CAPE treatment. Real-time-quaking induced conversion assay (RT-QuIC) technology was employed to explore the changes in fibril formation before and after CAPE treatment. The binding affinity between CAPE and murine recombinant full-length prion protein was determined using a molecular interaction assay. Results:CCK8 cell viability assay results demonstrated that treatment with 1 μmol/L CAPE for 3 and 7 days did not exhibit statistically significant differences in cell viability compared to the control group (all P<0.05). However, when the concentration of CAPE exceeded 1 μmol/L, a significant reduction in cell viability was observed in cells treated with CAPE for 3 and 7 days, compared to the control group (all P<0.05). Thus, 1 μmol/L was determined as the maximum safe concentration of CAPE treatment for SMB-S15 cells. The western blot results revealed that treatment with CAPE for both 3 and 7 days led to a detectable reduction in the levels of PrP Sc in SMB-S15 cells (all P<0.05). The products of PMCA experiments were assessed using western blot. The findings revealed a significant decrease in the levels of PrP Sc (relative grey value) in the PMCA amplification products of adapted-strains SMB-S15, 139A, and ME7 following treatment with CAPE, as compared to the control group (all P<0.05). The RT-QuIC experimental results demonstrated a reduction in fibril formation (as indicated by ThT peak values) in CAPE-treated mouse-adapted strains 139A, ME7, and SMB-S15, as well as in SMB-S15 cells infected with prions. Furthermore, CAPE exhibited varying degrees of inhibition towards different seed fibrils formation, with statistically significant differences observed (all P<0.05). Notably, CAPE exhibited a more pronounced inhibitory effect on ME7 seed fibrils. Molecular interaction analyses demonstrated significant binding between CAPE and murine recombinant prion protein, and the association constant was (2.92±0.41)×10 -6 mol/L. Conclusions:CAPE inhibits PrP Sc replication, amplification, and fibril formation in vitro possibly due to specific interactions with the prion protein at the molecular level.
