    Abstract Background: Ulcerative colitis is a chronic inflammatory disease with apparent extraintestinal manifestations, including in the oral cavity. Oral epithelial dysplasia, an exclusive histopathological diagnosis that is used to predict malignant transformation, has never been reported with ulcerative colitis. Herein, we report a case with ulcerative colitis that was diagnosed via extraintestinal manifestations of oral epithelial dysplasia and aphthous ulceration.
    Case presentation: A 52-year-old male suffering from ulcerative colitis came to our hospital complaining of pain on his tongue with a history of 1 week. Clinical examination revealed multiple painful oval ulcers on the ventral surfaces of the tongue. Histopathological examination indicated ulcerative lesion and mild dysplasia in the adjacent epithelium. Direct immunofluorescence demonstrated negative staining along the junction of the epithelium and lamina propria. Immunohistochemical staining with Ki-67, p16, p53 and podoplanin was used to rule out the reactive cellular atypia to inflammation and ulceration of the mucosa. A diagnosis of aphthous ulceration and oral epithelial dysplasia was made. The patient was treated with mouthwash (composed of lidocaine, gentamicin and dexamethasone) and triamcinolone acetonide oral ointment. Oral ulceration healed after one week of treatment. At the 12-month follow-up, minor scarring was observed on the right ventral surface of the tongue, and the patient felt no discomfort in the oral mucosa.
    Conclusion: Oral epithelial dysplasia might also occur in patients with ulcerative colitis despite the low incidence, which should broaden the understanding of oral manifestations of ulcerative colitis.

    Abstract This study presents two cases of lipid-rich pancreatic neuroendocrine tumors (PanNETs), a rare variant posing significant diagnostic challenges in fine needle aspiration (FNA) cytology and small biopsies. The first case involves an elderly male with a pancreatic tumor, displaying distinct cytoplasmic vacuoles, while the second case is a middle-aged male present with a pancreatic tail mass exhibiting foamy cytoplasm and eccentric nuclei, infiltrating in the stroma. Both cases did not exhibit typical morphologic features of PanNET but demonstrated cytomorphologic features and infiltrative growth patterns that mimicked adenocarcinoma. Further work-up demonstrated that both tumors were immunoreactive for synaptophysin and chromogranin, and were interpreted as well-differentiated, PanNET, lipid-rich variant. The study highlights the overlapping morphological features between lipid-rich PanNETs and other pancreatic neoplasms and underscores the importance of comprehensive cytological and immunohistochemical analysis for accurately diagnosing this variant, particularly due to the risk of misinterpreting it as pancreatic adenocarcinoma. Recognizing lipid-rich PanNETs is crucial for appropriate clinical management, as their identification can significantly impact treatment decisions and patient outcomes.

    Abstract Purpose: To investigate the potential mechanisms of scutellarin on oral leukoplakia (OLK) by network pharmacology and further verify by cytology.
    Methods: The potential targets of scutellarin acting on OLK were excavated through network pharmacology. PPI network was constructed, and the possible targets and pathways of scutellarin were predicted by GO and KEGG enrichment analysis. CCK-8 and Transwell assays were used to verify the effects of scutellarin on proliferation, migration and invasion of Leuk-1 and Cal-27 cell lines. The expression of related molecules was detected by Western blot to explore potential molecular mechanisms. Statistical analysis was performed with GraphPad Prism 9 software package.
    Results: There were 29 potential targets of scutellarin acting on OLK, of which HIF-1α was the key target, and the results of GO and KEGG analysis showed that scutellarin was highly involved in the response of cells and tissues to hypoxia and influenced HIF-1 signaling pathway. Scutellarin can significantly inhibit the proliferation (IC
    Conclusions: Scutellarin can inhibit carcinogenesis of OLK by suppressing HIF-1 signaling pathway.

    Abstract Background: Hemorrhagic transformation (HT) caused by blood-brain barrier (BBB) damage is closely correlated with the poor prognosis of ischemic stroke. Neutrophils are proven to mediate BBB injury after ischemic stroke, but the mechanism remains to be further investigated. Therefore, the present study aims to investigate the effect of neutrophil-derived exosomes on BBB integrity.
    Method: A tMCAO-HT model was constructed to assess neutrophil infiltration and its co-localization with brain microvascular endothelial cells (BMEC). After using quiet (Q-Neu) and activated neutrophil (A-Neu) and their exosomes to treat the BBB model in vitro, TEER and permeability were assayed to assess the BBB integrity. Small RNA sequencing was performed to identify differentially expressed miRNAs (DE-miRNAs) in A-Neu- and Q-Neu-derived exosomes, and the function and pathways of DE-miRNA targets were analyzed by GO and KEGG enrichment.
    Result: Different degrees of cerebral hemorrhage were observed in the tMCAO-HT model. The expression of the neutrophil marker Ly6G was significantly increased in tMCAO-HT model compared to the sham group, and co-localized with the BMEC marker CD31. Notably, Ly6G expression was positively correlated with hemoglobin content in brain tissue. A-Neu and its derived exosomes reduced TEER and elevated permeability in the BBB model in vitro. Moreover, BBB-related proteins Claudin 5, Occludin and ZO-1 expression were significantly reduced in BMEC after treatment with A-Neu and its derived exosomes. Nevertheless, Q-Neu and its exosomes had no significant effect on BBB integrity. A total of 84 DE-miRNAs are present in Q-Neu- and A-Neu-derived exosomes, and their target genes are involved in the regulation of "positive regulation of establishment of endothelial barrier", "cell junction", "ECM-receptor interaction" and "VEGF signaling pathway". Moreover, RT-qPCR revealed that the expression trends of miR-409-3p, miR-6909-5p, miR-3473d, miR-370-3p and miR-6904-5p in exosomes were consistent with the sequencing results.
    Conclusion: Neutrophils are abnormally recruited in HT after ischemic stroke, and are associated with cerebral hemorrhage. In vitro, A-Neu-derived exosomes facilitate BBB injury, which may be accomplished by exosomal transport of miRNAs.

    Abstract Background and objectives: Platelet has been linked to thrombosis in several studies. Inflammation is closely intertwined with thrombosis and occurs consecutively; it is therefore conceivable that platelet transfusions perform an increasingly vital role in inflammation. As platelet transfusions have been a significant therapeutic approach in patients for decades, serious risks including viral transmission, bacterial sepsis and acute lung injury have been demonstrated by retrospective studies and randomized clinical trials. Recent data suggest associations among platelet transfusion and pro-inflammatory responses.
    Materials and methods: A systematic review (from 2014 to 2019) on English literatures was conducted. Data on platelet transfusion-related reactions were abstracted. Preset inclusion and exclusion criteria were applied to identify all eligible articles.
    Results: All patients abstracted have received platelet transfusion. This new review focuses on recent 5-year advances (from 2014 to 2019) to have found that the platelet transfusion as pro-inflammatory process, concerning secretion of platelet microparticles and other inflammatory factors.
    Conclusion: It can be hypothesized that the platelet microparticles or biological response modifier pathways might be innovative and therapeutic approaches to improving platelet transfusion and pretransfusion manipulations to reduce transfusion-related adverse reactions and therefore improve the efficacy and safety of this wide-employed therapy.

    Abstract Background and objectives: In the absence of a vaccine or specific drug treatment options for coronavirus disease (COVID-19), attention has been shifted in China to the possible therapeutic use of convalescent plasma. COVID-19 convalescent plasma (CCP) is currently under investigation. We summarized clinical studies and other research data available as of 5 May 2020 on CCP therapy according to the Clinical Treatment Guideline of COVID-19 Convalescent Plasma in China, as well as clinical experience at the First Affiliated Hospital of Zhejiang University, as part of a comprehensive anti-epidemic strategy.
    Materials and methods: As of 5 May 2020, when the epidemic was well-controlled in China, healthcare databases and sources of English literature relating to convalescent plasma were searched and reviewed. Sources of clinical and methodological heterogeneity were identified.
    Results: As of 5 May 2020, up to 2000 samples of CCP had been collected across China and administered to 700 COVID-19 patients. From donors, 200-400 ml of plasma was collected at each donation, with antibody titres > 1:160. We identified three clinical studies for COVID-19 in China. Analyses showed a statistically significant improvement in clinical outcomes compared with untreated cases (P < 0.001). No adverse effects were reported.
    Conclusion: From initial studies, convalescent plasma therapy appears effective and safe for COVID-19. However, there is clearly a need for well-designed RCTs (randomized controlled trials) or other formal studies to further evaluate the efficacy and any potential adverse effects of CCP.

    Abstract Hyperfibrinogenemia had been widely observed in various cancer patients, however, whether fibrinogen (FIB) influences the survival outcome of patients with primary liver cancer (PLC) remains unknown. This study was aimed to evaluate the predictive value of preoperative FIB in the survival outcome of PLC patients and explore the possible mechanism. Retrospective study was performed in PLC patients who underwent hepatectomy. Logistic regression analysis was used to explore the independent risk factors of the overall survival (OS) of PLC patients. The predictive value of FIB for the survival outcome was analyzed by Kaplan-Meier method, receiver operating characteristic curve and Cox proportional hazard model combined with B-splines. Hepatoma cell migration and invasion were detected by wound healing assay and Transwell assay, protein expression was measured by Western blot. mTOR inhibitor and PTEN overexpression plasmid were used to confirm the involvement of the PTEN/AKT/mTOR pathway during FIB treatment. Preoperative FIB was confirmed to be related with the OS in PLC patients, higher FIB (>2.5 g/L) indicated higher hazard ratio. Meanwhile, FIB could promote hepatoma cell migration and invasion through the activation of AKT/mTOR pathway and epithelial-mesenchymal transformation (EMT). Moreover, the promotion of FIB on cell migration and invasion could be inhibited by mTOR inhibitor and PTEN overexpression. Preoperative FIB could be related with the prognosis of PLC patients, the risk of death in PLC patients gradually increases along with the up-regulation of FIB. FIB may promote hepatoma metastasis by inducing EMT via the activation of PTEN/AKT/mTOR pathway.

    Abstract Bacterial viruses are the most abundant biological entities in soil ecosystems. Owing to the advent of metagenomics and viromics approaches, an ever‐increasing diversity of virus‐encoded auxiliary metabolic genes (AMGs) have been identified in soils, including those involved in the transformation of carbon, phosphorus, and sulfur, degradation of organic pollutants, and antibiotic resistance, among other processes. These viral AMGs can alter soil biogeochemical processes and metabolic activities by interfering with bacterial host metabolism. It is recognized that viral AMGs compensate for host bacterial metabolism outputs by encoding accessory functional genes and are favourable for the hosts' adaptation to stressed soil environments. The eco‐evolutionary mechanisms behind this fascinating diversity of viral AMGs in soil microbiomes have begun to emerge, such as horizontal gene transfer, lytic‐lysogenic conversion, and single‐nucleotide polymorphisms. In this mini‐review, we summarize recent advances in the diversity and function of virus‐encoded AMGs in the soil environment, especially focusing on the evolutionary significance of AMGs involved in virus‐host interactions. This mini‐review also sheds light on the existing gaps and future perspectives that could have major significance for viral AMGs research in soils.
