Ischemic stroke is the leading cause of death and disability among adults worldwide. T lymphocytes can be divided into αβT cells and γδT cells. Among them, αβT cells can be further divided into subgroups such as CD4? T cells, CD8? T cells, and natural killer (NK) cells. In CD4? T cells, T helper cells (Th) 1 and Th17 secrete pro-inflammatory cytokines, which can exacerbate ischemic brain injury; Th2 secretes anti-inflammatory factors, which can improve neurological function. Regulatory T cells (Tregs) exert neuroprotective effects through various mechanisms. CD8? T cells exacerbate ischemic brain injury by secreting cytokines and releasing granzyme, while NK cells can cause neuronal damage and blood-brain barrier damage by secreting interferon-γ. In addition, interleukin-17 secreted by γδT cells also plays a significant pro-inflammatory role in the pathological process of stroke. Therefore, a deeper understanding of the role of T lymphocytes can provide new ideas for the treatment of ischemic stroke.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

OBJECTIVE: To investigate the effects of sodium valproate (VPA) in inhibiting Erastin-induced ferroptosis in bone marrow mesenchymal stem cells (BMSCs) and its underlying mechanisms. METHODS: BMSCs were isolated from bone marrow of 8-week-old Spragur Dawley rats and identified [cell surface antigens CD90, CD44, and CD45 were analyzed by flow cytometry, and osteogenic and adipogenic differentiation abilities were assessed by alizarin red S (ARS) and oil red O staining, respectively]. Cells of passage 3 were used for the Erastin-induced ferroptosis model, with different concentrations of VPA for intervention. The optimal drug concentration was determined using the cell counting kit 8 assay. The experiment was divided into 4 groups: group A, cells were cultured in osteogenic induction medium for 24 hours; group B, cells were cultured in osteogenic induction medium containing optimal concentration Erastin for 24 hours; group C, cells were cultured in osteogenic induction medium containing optimal concentration Erastin and VPA for 24 hours; group D, cells were cultured in osteogenic induction medium containing optimal concentration Erastin and VPA, and 8 μmol/L EX527 for 24 hours. The mitochondrial state of the cells was evaluated, including the levels of malondialdehyde (MDA), glutathione (GSH), and reactive oxygen species (ROS). Osteogenic capacity was assessed by alkaline phosphatase (ALP) activity and ARS staining. Western blot analysis was performed to detect the expressions of osteogenic-related proteins [Runt-related transcription factor 2 (RUNX2) and osteopontin (OPN)], ferroptosis-related proteins [glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), and solute carrier family 7 member 11 (SLC7A11)], and pathway-related proteins [adenosine monophosphate-activated protein kinase (AMPK) and Sirtuin 1 (SIRT1)]. RESULTS: The cultured cells were identified as BMSCs. VPA inhibited Erastin-induced ferroptosis and the decline of osteogenic ability in BMSCs, acting through the activation of the AMPK/SIRT1 pathway. VPA significantly reduced the levels of ROS and MDA in Erastin-treated BMSCs and significantly increased GSH levels. Additionally, the expression levels of ferroptosis-related proteins (GPX4, FTH1, and SLC7A11) significantly decreased. VPA also upregulated the expressions of osteogenic-related proteins (RUNX2 and OPN), enhanced mineralization and osteogenic differentiation, and increased the expressions of pathway-related proteins (AMPK and SIRT1). These effects could be reversed by the SIRT1 inhibitor EX527. CONCLUSION VPA inhibits ferroptosis in BMSCs through the AMPK/SIRT1 axis and promotes osteogenesis.

With the application of FOLFOX regimen (oxaliplatin, fluorouracil, and leucovorin) in hepatic arterial perfusion (HAIC), chemotherapy has shown a higher value in the comprehensive treatment of hepatocellular carcinoma. Especially in the era of integration of targeted therapy and immunotherapy, the FOLFOX-HAIC, combined with immunotherapy and targeted therapy, further improves antitumor effect. The FOLFOX systemic chemotherapy combined with immunotherapy and targeted therapy scheme explored by the authors has achieved similar effects to triple therapy. Advanced hepatocellular carcinoma exhibits systemic disease characteristics, and systemic chemotherapy combined with targeted and immunotherapy has achieved higher disease control rates in the initial exploration. The mechanism may be that systemic chemotherapy changes the overall immune micro-environment of tumors, transforming the immune microenvironment from immunosuppressive to immune supportive, thereby better enhancing the efficacy of immunotherapy. The optimal regimen of systemic chemotherapy in comprehensive treatment may be obtained from the phase 3 study and basic studies in the future, which will be more efficient, safe and economical in the treatment of advanced hepatocellular carcinoma.
