Amanitin-containing mushroom poisoning is one of the most harmful and lethal types of mushroom poisoning events. Its basic medical and clinical medical knowledge has not been fully understood and mastered, so the basic and clinical diagnosis and treatment of amanitin-containing mushroom poisoning has always been a hot research field of acute mushroom poisoning. This article focuses on the new progress in the epidemiology, toxicological properties, poisoning mechanism, clinical diagnosis and treatment of amanitin-containing mushroom poisoning, in order to provide the basis for further study, diagnosis and treatment of amanitin-containing mushroom poisoning for basic researchers and clinical medical staff.
ObjectiveTo summarize the possible roles and relevant mechanisms of solute carrier family 3 member A2 (SLC3A2) gene in hepatocellular carcinoma (HCC), and explore its clinical application prospects and value in the diagnosis, treatment, and prognosis of patients with HCC. MethodThe literature on reseaches of the SLC3A2 gene and its association with HCC both domestically and internationally in recent years was reviewed and summarized. ResultsNotably, the SLC3A2 exhibited obviously elevated expression in the HCC tissue as compared with the normal liver tissue. It mainly affected the disease progression of HCC by regulating the intracellular and extracellular amino acids transport, inhibiting the ferroptosis of cells, activating the mechanistic target of rapamycin complex signaling pathways and integrin signaling pathway, and played an important role in the diagnosis, treatment, and prognosis of patients with HCC. ConclusionFrom the results of literature review collected, SLC3A2 might be closely associated with the migration, invasion, proliferation, and apoptosis of HCC cell, and it is expected to serve as an indicator for evaluating survival and prognosis of patients with HCC, and become one of the effective treatment targets for HCC in future.
Objective To understand the role and mechanism of tumor associated macrophages (TAM) on the occurrence and development of primary liver cancer, and its application in the treatment. MethodThe related literatures about the researches of relation between TAM and primary liver cancer at home and abroad in recent years were collected, sorted out, and made a review. Results Under different stimulating factors, TAM could be polarized to anti-tumor type 1 TAMs or tumor-promoting type 2 TAMs, and type 2 TAMs was the main part in the tumor microenvironment. Through some mechanisms such as vascularity-promoting, invasion-promoting, and immunosuppression to promote the occurrence and development of tumors, and potential treatment plans for primary liver cancer could be found by targeting TAM from different perspectives. Conclusion TAM has a wide range of effects on primary liver cancer, and their mechanisms are complex, understanding the relation between them and make an effective control of TAM could provide new therapeutic ideas and plans for clinical treatment of primary liver cancer.
Most immune-related adverse event (irAE) associated with immune checkpoint inhibitors (ICIs) resulted from excessive immune response against normal organs. The severity, timing, and organs affected by these events were often unpredictable. Adverse reactions could cause treatment delays or interruptions, in rare cases, pose a life-threatening risk. The mechanisms underlying irAE involved immune cell dysregulation, imbalances in inflammatory factor expression, alterations in autoantibodies and complement activation, even dysbiosis of intestinal microorganisms. However, the mechanisms of irAE occurrence might differ slightly among organs due to variations in their structures and the functions of resident immune cells. Future research should focus on the development of targeted drugs for the prevention or treatment of irAE based on the mechanisms by which irAE occurs in different organs. A deeper understanding of the mechanisms underlying irAE occurrence would aid clinicians in effectively utilizing ICIs and provide valuable guidance for their clinical application.
Bacterial biofilm is the key problem of chronic wound infection and difficult healing. How to prevent and control bacterial biofilm and improve the prognosis of chronic wound has become a research hotspot in the field of wound care. This paper will summarize from the following aspects: four major stages in the process of chronic wound bacteria biofilm formation (surface adhesion, formation of small colonies, biofilm maturation, and dispersion and separation); characteristics of host immune response in the presence of biofilms; morphological, microbiological, and molecular detection methods for biofilms; and progress in in vitro trials, animal trials, clinical trials, and new therapeutic methods of biofilm. The purpose of this review is to provide evidence for the treatment of biofilms for chronic wounds.
Iron death is an alternative to normal cell death and is regulated by a variety of cellular metabolic pathways. Iron death has become a hot topic of research because it can cause damage to various organs and degenerative diseases in the body. Metabolism, signalling pathways, endoplasmic reticulum stress, and immune cells can all affect the occurrence of iron death, and the blood-retina destruction induced by iron death plays an important role in autoimmune uveitis. Exploring the components of the blood-retina regulatory mechanism of iron death in autoimmune uveitis can lead to the search for targeted drug targets, which can provide a new research idea for the subsequent study of the diagnosis and treatment of autoimmune uveitis.
