    Abstract Immune checkpoint inhibitors (ICIs) are commonly utilized in tumor treatment. However, they still have limitations, including insufficient effectiveness and unavoidable adverse events. It has been demonstrated that gut microbiota can influence the effectiveness of ICIs, although the precise mechanism remains unclear. Gut microbiota plays a crucial role in the formation and development of the immune system. Gut microbiota and their associated metabolites play a regulatory role in immune balance. Tumor occurrence and development are linked to their ability to evade recognition and destruction by the immune system. The purpose of ICIs treatment is to reinitiate the immune system's elimination of tumor cells. Thus, the immune system acts as a communication bridge between gut microbiota and ICIs. Varied composition and characteristics of gut microbiota result in diverse outcomes in ICIs treatment. Certain gut microbiota-related metabolites also influence the therapeutic efficacy of ICIs to some extent. The administration of antibiotics before or during ICIs treatment can diminish treatment effectiveness. The utilization of probiotics and fecal transplantation can partially alter the outcome of ICIs treatment. The present review synthesized previous studies to examine the association between gut microbiota and ICIs, elucidated the role of gut microbiota and its associated factors in ICIs treatment, and offered direction for future research.

    Abstract Triclosan (TCS) and tetracycline (TC) are commonly detected antibacterial agents in sewage and environment matrices. Nonetheless, the impact of sequential exposure to TCS and TC on the methanogenic digestion microbiome remains unknown. In this study, TCS was shown to reduce COD removal efficiency to 69.8%, but alleviated the inhibitive effect of consequent TC-amendment on the digestion microbiome. Interestingly, TCS pre-exposure resulted in abundance increase of acetotrophic Methanosaeta to 2.68%, being 2.91 folds higher than that without TCS amendment. Microbial network analyses showed that TCS pre-exposure caused microorganisms to establish a co-ecological relationship against TC disturbance. Further analyses of total antibiotic resistance genes (ARGs) showed the TCS-derived compromise of TC-induced ARGs enrichment in digestion microbiomes, e.g., 238.2% and 152.1% ARGs increase upon TC addition in digestion microbiomes without and with TCS pre-exposure, respectively. This study provides new insights into the impact of antibacterial agents on the methanogenic digestion microbiome.

    Abstract Microorganisms play key roles in the conversion of organic matter in foodwaste. However, both the microbially-mediated element (carbon/C and nitrogen/N) flows and associated microbial communities in foodwaste treatment plants (FWTPs) remain unclear. This study collected samples of different foodwaste treatment units from five full-scale FWTPs to analyze the C/N flows and microbial communities in foodwaste treatment processes. Results showed that 39.8-45.0% of organic carbon in foodwaste was converted into biogas. Hydrolytic acidogenic bacteria (e.g., Lactobacillus and Limosilactobacillus) and eukaryota (e.g., Cafeteriaceae, Saccharomycetales, and Agaricomycetes) were more abundant in feedstock and pretreatment units. Redundancy analyses showed that acidogens were major players in the transformation of foodwaste organic matter. Populations of W27 and Tepidanaerobacter were major contributors to the difference in conversion of C/N in these FWTPs. This study could support foodwaste treatment efficiencies improvement by providing insights into C/N flows and associated microbiota in FWTPs.

    Abstract Soil solarization (SS) is a technique for managing pathogens and weeds, which involves covering with transparent plastic to increase soil temperature during summer fallow (SF). However, SS also alters the diversity of bacterial communities. Therefore, during SF, various organic modifiers are used in combination with SS to improve its efficacy. Organic amendments may contain antibiotic resistance genes (ARGs). Greenhouse vegetable production (GVP) soils are vital to ensure food security and ecological balance. However, comprehensive study on the effects of SS combined with different types of manure on ARGs in GVP soils during SF remains unclear. Therefore, this study employed high-throughput qPCR to explore the effects of different organic amendments combined with SS on the abundance changes of ARGs and mobile genetic elements (MGEs) in GVP soils during SF. The abundance and diversity of ARGs and MGEs in GVP soils with different manure fertilization and SS decreased during SF. Horizontal gene transfer via MGEs (especially integrases 45.80%) induced by changes in environmental factors (NO₃⁻-N 14.7% and NH₄⁺-N) was the main factor responsible for the changes in ARGs. Proteobacteria (14.3%) and Firmicutes were the main potential hosts of ARGs. Network analysis suggested that Ornithinimicrobium, Idiomarina and Corynebacterium had positive correlations with aminoglycosides, MLSB, and tetracycline resistance genes. These results provide new insights to understand the fate of ARGs in the GVP soils by manure-amended combined with SS during SF, which may help to reduce the spread of ARGs.

    Abstract 3D bioprinting technology is widely used to fabricate various tissue structures. However, the absence of vessels hampers the ability of bioprinted tissues to receive oxygen and nutrients as well as to remove wastes, leading to a significant reduction in their survival rate. Despite the advancements in bioinks and bioprinting technologies, bioprinted vascular structures continue to be unsuitable for transplantation compared to natural blood vessels. In addition, a complete assessment index system for evaluating the structure and function of bioprinted vessels in vitro has not yet been established. Therefore, in this review, we firstly highlight the significance of selecting suitable bioinks and bioprinting techniques as they two synergize with each other. Subsequently, focusing on both vascular-associated cells and vascular tissues, we provide a relatively thorough assessment of the functions of bioprinted vascular tissue based on the physiological functions that natural blood vessels possess. We end with a review of the applications of vascular models, such as vessel-on-a-chip, in simulating pathological processes and conducting drug screening at the organ level. We believe that the development of fully functional blood vessels will soon make great contributions to tissue engineering and regenerative medicine.

    Abstract The role of ferroptosis in human acute lymphoblastic leukemia and its possible molecular mechanisms of action are still unknown. In this study, harvested Molt-4 cells were exposed to different concentrations of erastin, and their proliferation capacity was tested by using the cell counting kit-8 assay. Lipid peroxidation levels were detected through flow cytometry. Mitochondrial alterations were observed through transmission electron microscopy. The expression levels of SLC7A11, glutathione peroxidase 4 (GPX4), and mitogen-activated protein kinase (MAPK) were detected by using quantitative real-time PCR and Western blot analysis. This study found that erastin inhibited the growth of Molt-4 cells. This inhibitory effect could be partially reversed by the ferroptosis inhibitor Ferrostatin-1 and the p38 MAPK inhibitor. The mitochondria of Molt-4 cells treated with erastin shortened and condensed. Compared with those in the control group, the levels of reactive oxygen species and malondialdehyde had increased, whereas the levels of glutathione had decreased in the treatment group. The treatment of Molt-4 cells with erastin decreased the levels of SLC7A11 and GPX4 mRNA and increased the expression levels of p38 MAPK, extracellular signal-regulated kinase (ERK), and c-Jun N-terminal kinase. These findings suggested that erastin caused the ferroptosis of Molt-4 cells. This process may be correlated with the inhibition of the cystine/glutamate antiporter system and GPX4 and the activation of p38 MAPK and ERK1/2.

    Abstract Objective: To explore the mediating effect of coping style between illness perception and fear of cancer recurrence in patients undergoing radical prostatectomy.
    Methods: A questionnaire survey was carried out in 254 eligible patients who underwent radical prostatectomy in the urology department of two comprehensive tertiary hospitals in Wenzhou City from June 2022 to December 2022. The questionnaires include the general data questionnaire, brief illness perception questionnaire (BIPQ), Medical Coping Modes Questionnaire (MCMQ) and Fear of Progression Questionnaire-Short Form (FoP-Q-SF). A structural equation model was used to analyze the mediating effect of coping style between illness perception and fear of cancer recurrence.
    Results: The score of fear of cancer recurrence in prostate cancer patients is (30.08 ± 10.11). Illness perception, avoidance, and surrender coping styles could forward prediction fear of cancer recurrence (P=0.001, P=0.019, P=0.001); facing coping styles can negatively predict fear of cancer recurrence (P=0.001). Coping style played a part of the mediating role between illness perception and fear of cancer recurrence, and the mediating effect is 0.150,which accounted for 47.62% of the total effect.
    Conclusion: Coping style is a mediator between illness perception and fear of cancer recurrence in patients undergoing radical prostatectomy. Doctors and nurses should reduce patients' negative perception, guide them to adopt positive coping strategies, and thereby reduce their fear of cancer recurrence.

    Abstract Applying exogenous additives during the aerobic composting of livestock manure is effective for slowing down the spread of antibiotic resistance genes (ARGs) in the environment. Nanomaterials have received much attention because only low amounts need to be added and they have a high capacity for adsorbing pollutants. Intracellular ARGs (i-ARGs) and extracellular ARGs (e-ARGs) comprise the resistome in livestock manure but the effects of nanomaterials on the fates of these different fractions during composting are still unclear. Thus, we investigated the effects of adding SiO₂ nanoparticles (SiO₂NPs) at four levels (0 (CK), 0.5 (L), 1 (M), and 2 g/kg (H)) on i-ARGs, e-ARGs, and the bacterial community during composting. The results showed that i-ARGs represented the main fraction of ARGs during aerobic composting of swine manure, and their abundance was lowest under M. Compared with CK, M increased the removal rates of i-ARGs and e-ARGs by 17.9% and 100%, respectively. SiO₂NPs enhanced the competition between ARGs hosts and non-hosts. M optimized the bacterial community by reducing the abundances of co-hosts (Clostridium_sensu_stricto_1, Terrisporobacter, and Turicibacter) of i-ARGs and e-ARGs (by 96.0% and 99.3%, respectively) and killing 49.9% of antibiotic-resistant bacteria. Horizontal gene transfer dominated by mobile genetic elements (MGEs) played a key role in the changes in the abundances of ARGs. i-intI1 and e-Tn916/1545 were key MGEs related closely to ARGs, and the maximum decreases of 52.8% and 100%, respectively, occurred under M, which mainly explained the decreased abundances of i-ARGs and e-ARGs. Our findings provide new insights into the distribution and main drivers of i-ARGs and e-ARGs, as well as demonstrating the possibility of adding 1 g/kg SiO₂NPs to reduce the propagation of ARGs.
