OBJECTIVE To explore the action mechanism of kushenol F (KSCF) in treating ulcerative colitis (UC) in mice. METHODS The potential targets of KSCF intervening in UC were predicted with network pharmacology and molecular docking. C57BL/6J mice were randomly divided by body weight into model group, positive control group (sulfasalazine, 703 mg/kg), KSCF group (100 mg/kg), and normal group, with 6 mice per group. The UC model of mice was induced by dextran sulfate sodium solution. During the modeling period, the mice were given relevant medicine intragastrically, once a day, for 7 consecutive days. After the last administration, the disease activity index (DAI) of the mice was scored; the length of the mice’s colon was measured; pathological changes in the colon tissue of mice were observed; the levels of lipopolysaccharide (LPS) in serum, myeloperoxidase (MPO), nitric oxide (NO) and superoxide dismutase (SOD) in the colon were detected in mice; the expression levels of occludin and ZO-1 in colon tissue of mice were detected; the proportions of CD3+T, CD4+T, and CD8+T lymphocytes in the spleen and the ratio of CD4+/CD8+ were detected; changes in colonic microbiota were analyzed by 16S rDNA sequencing. RESULTS Results of network pharmacology indicated that KSCF may treat UC by regulating signaling pathways such as phosphatidylinositol-3 kinase/protein kinase B (PI3K/AKT) and nuclear factor kappa B (NF- κB). Molecular docking results showed that KSCF bound most stably with NF-κB p65 protein. Animal experiment results demonstrated that, compared with the model group, the pathological characteristics of colon tissue in mice were improved in KSCF group. DAI scores, serum levels of LPS, the levels of MPO,NF-κB p65 phosphorylation and NLRP3 protein expression in the colon, and the proportion of CD8+T lymphocytes in the spleen were reduced significantly (P<0.05). Body weight, SOD levels, expression levels of occludin and ZO-1 in the colon, proportions of CD3+T and CD4+T lymphocytes, and the CD4+/CD8+ ratio in the spleen were significantly increased (P<0.05); the abundance of Firmicutes, Actinobacteria, Akkermansia, and Lactobacillus genera were increased, while Proteobacteria decreased; the microbial community structure tended towards that of the normal group. CONCLUSIONS KSCF alleviates UC by restoring intestinal microbial imbalance, enhancing immune response, and inhibiting colonic inflammatory responses, thereby improving intestinal barrier integrity.

[Objective] To explore the expression of Nectin-4 in invasive bladder urothelial carcinoma (BUC) tissue and its clinical significance, so as to provide reference for clinical diagnosis and treatment of BUC. [Methods] Nectin-4 expression in 60 cases of invasive BUC and 40 cases of chronic inflammation of bladder mucosa was detected with immunohistochemical staining (IHC) and RNAscope.The results of the two methods were analyzed and compared, and the relationship between the two methods and the clinicopathological characteristics of invasive BUC was discussed.The correlation between the protein expression of Nectin-4 in BUC tissues, human epidermal growth factor receptor 2 (Her-2) and programmed death factor ligand 1 (PD-L1) was analyzed. [Results] The positive protein expression rates of Nectin-4 detected by IHC were 78.33%(47/60) and 17.50% (7/40) in the invasive BUC group and inflammatory group, respectively, while the positive mRNA expression rates of Nectin-4 detected by RNAscope were 83.33% (50/60) and 12.50% (5/40), respectively.The Kappa values of Nectin-4 in the invasive BUC group and inflammatory group were 0.732 and 0.610, respectively, with general consistency.The protein expression of Nectin-4 in invasive BUC was correlated with muscular invasion, histological grade, vascular thrombus, lymph node metastasis and clinical stage (P<0.05). The mRNA expression of Nectin-4 in invasive BUC was correlated with max tumor diameter, muscular invasion, histological grade, vascular thrombus, lymph node metastasis and clinical stage (P<0.05). The high expression of Nectin-4 in invasive BUC was positively correlated with the expression of Her-2 (P=0.002), but not with the expression of PD-L1 (P>0.05). [Conclusion] Nectin-4 is highly expressed in invasive BUC, and is usually associated with the pathological parameters of poor prognosis.Detection of Nectin-4 expression will help to guide clinical diagnosis and treatment.

Objective:To explore the neuroprotective effect and molecular mechanism of sulforaphane (SFN) on acute carbon monoxide poisoning (ACOP) in rats.Methods:A total of 135 healthy adult male Sprague-Dawley (SD) rats were randomly divided into normal control group, ACOP model group, and SFN intervention group, with 45 rats in each group. The ACOP animal model was reproduced using carbon monoxide (CO) inhalation in a hyperbaric oxygen chamber, while the normal control group was allowed to breathe fresh air freely. The rats in the SFN intervention group received intraperitoneal injection of SFN at a dose of 20 mg/kg once daily starting 2 hours after CO poisoning and continuing until euthanasia. The normal control group and the ACOP model group received equivalent volume of saline injection. Three rats from each group were sacrificed 1 day after intervention to observe the changes in the ultrastructure of neuronal mitochondria in brain tissues under transmission electron microscopy. Six rats from each group were evaluated for cognitive function using neurobehavioral test 7 days after intervention. Brain tissues of 6 rats in each group were collected 1, 3, and 7 days after intervention, and the expressions of phosphorylated-adenosine monophosphate-activated protein kinase (p-AMPK), mitofusin 2 (MFN2), and dynamin-related protein 1 (DRP1) were detected using immunohistochemistry staining and Western blotting. Linear regression analysis was performed to assess the correlations between the expression levels of above proteins.Results:In the normal control group, the rats did not exhibit any abnormalities in cognitive function or the ultrastructure of neuronal mitochondria in brain tissues. ACOP induced cognitive impairment and ultrastructural injury to neuronal mitochondria in rats. However, SFN significantly improved cognitive function in poisoned rats and mitigated the extent of neuronal mitochondrial damage. Over poisoning time, the expression levels of p-AMPK and MFN2 in the brain tissues of ACOP rats were gradually decreased, while the expression level of DRP1 was gradually increased. Compared with the normal control group, the ACOP model group showed significant differences in the expressions of p-AMPK, MFN2, and DRP1. After SFN intervention, the expression levels of above proteins were significantly reversed. Compared with the ACOP model group, the SFN intervention group exhibited a marked increase in the expressions of p-AMPK and MFN2 [p-AMPK positive expression ( A value): 0.226±0.003 vs. 0.177±0.033, p-AMPK protein (p-AMPK/GAPDH): 1.41±0.05 vs. 0.89±0.05, MFN2 positive expression ( A value): 0.241±0.004 vs. 0.165±0.007, MFN2 protein (MFN2/GAPDH): 1.33±0.04 vs. 0.79±0.03, all P < 0.05], along with a significant decrease in DRP1 expression [DRP1 positive expression ( A value): 0.103±0.002 vs. 0.214±0.011, DRP1 protein (DRP1/GAPDH): 1.00±0.03 vs. 1.50±0.03, both P < 0.05]. Linear regression analysis revealed a strong negative linear correlation between DRP1 protein expression and MFN2, p-AMPK protein expressions ( R2 values were 0.977 and 0.971, both P < 0.01), and a positive linear correlation between p-AMPK protein expression and MFN2 protein expression ( R2 = 0.985, P < 0.01). Conclusion:SFN can help maintain neuronal mitochondrial homeostasis by activating the adenosine monophosphate-activated protein kinase (AMPK) signaling pathway, thereby alleviating neuronal injury caused by ACOP.

Objective:To explore the current status of rumination in inpatients with metastatic prostate cancer (mPCa) under the disease coping mechanism, and analyzing its influencing factors.Methods:From March 2021 to December 2022, 267 mPCa inpatients at the Tenth People's Hospital of Tongji University were selected as the study subject using convenience sampling. The survey was conducted using the General Information Questionnaire, Chinese Version of Event Relate Rumination Inventory (C-ERI), Medical Coping Modes Questionnaire (MCMQ), International Prostate Symptom Score (IPSS), and Social Support Revalued Scale (SSRS), and the factors influencing the rumination in patients were analyzed.Results:This study collected 260 valid questionnaires, with an effective response rate of 97.4% (260/267). The total score of rumination in 260 mPCa patients was (31.08±6.46), with invasive rumination and purposeful rumination scores of (14.13±4.44) and (16.95±4.55), respectively. The initial prostate-specific antigen index, confrontation medical coping modes were the influencing factors of invasive rumination in mPCa patients ( P<0.05). The initial prostate-specific antigen index, course of disease, social support, and confrontation medical coping style were the influencing factors of purposeful rumination in mPCa patients ( P<0.05) . Conclusions:The rumination of mPCa patients is above the medium level, and is influenced by multiple factors under the disease coping mechanism. Clinical medical and nursing staff should combine the clinical situation and characteristics of mPCa patients, provide personalized interventions as early as possible, and assist patients in improving their positive cognitive processing abilities.

The advent of chimeric antigen receptor (CAR)-T cell immunotherapies has led to breakthroughs in the treatment of hematological malignancies. However, their success in treating solid tumors has been limited. CAR-natural killer (NK) cells have several advantages over CAR-T cells because NK cells can be made from pre-existing cell lines or allogeneic NK cells with a mismatched major histocompatibility complex (MHC), which means they are more likely to become an "off-the-shelf" product. Moreover, they can kill cancer cells via CAR-dependent/independent pathways and have limited toxicity. Macrophages are the most malleable immune cells in the body. These cells can efficiently infiltrate into tumors and are present in large numbers in tumor microenvironments (TMEs). Importantly, CAR-macrophages (CAR-Ms) have recently yielded exciting preclinical results in several solid tumors. Nevertheless, CAR-T, CAR-NK, and CAR-M all have their own advantages and limitations. In this review, we systematically discuss the current status, progress, and the major hurdles of CAR-T cells, CAR-NK cells, and CAR-M as they relate to five aspects: CAR structure, therapeutic mechanisms, the latest research progress, current challenges and solutions, and comparison according to the existing research in order to provide a reasonable option for treating solid tumors in the future.

Objective To investigate the correlation between pre-treatment pan-immune inflammation value (PIV) and clinicopathological features in esophageal squamous cell carcinoma (ESCC) patients with postoperative adjuvant radiotherapy and evaluate its value in prognosis assessment combined with T stage. Methods A retrospective analysis was conducted on data of 85 ESCC patients with postoperative adjuvant radiotherapy in the Department of Radiation Oncology of the Affiliated Hospital of Yangzhou University from January 2019 to January 2023. The receiver operating characteristic (ROC) curve was drew to obtain the optimal cut-off value of PIV and other immune-inflammatory biomarkers. The area under the curve (AUC) and clinical applicability of PIV and other immune-inflammatory biomarkers were compared based on the ROC curve and decision curve analysis (DCA). According to the optimal cut-off value, patients were divided into high PIV group and low PIV group, and the correlation between PIV level and clinicopathological features of ESCC was evaluated. Kaplan-Meier method was used for survival analysis, the Cox proportional hazards model was used for multivariate analysis, and a risk stratification model combining PIV and T stage was established by recursive partitioning analysis (RPA). Results The optimal cut-off value of pre-treatment PIV was determined as 187.22 based on the ROC curve. The AUC of PIV was 0.679, which was greater than 0.640, 0.583, 0.656 and 0.644 of the other four immune-inflammatory biomarkers such as the systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and neutrophil-to-lymphocyte ratio (NLR). The 85 patients were divided into low PIV group (< 187.22,
