  • 骨关节炎病理进程相关机制的研究进展

    骨关节炎(OA)的发病机制比较复杂,其发生与年龄、性别、遗传、肥胖、创伤有关。目前对于OA的治疗还没有很好的措施,其发生后病情发展的机制研究成为本领域的研究重点。目前已发现与OA病情发展相关的细胞因子、信号通路、蛋白酶类的作用机制的研究均处于初级阶段,且以各种作用机制指导的临床治疗措施效果欠佳。为进一步明确OA发展的相关病理机制,现对近几年来国内外本领域的相关研究作一综述,为探索更加有效的治疗方法提供新的理论依据。

  • Research progress on functions and mechanisms of solute carrier family 3 member A2 in hepatocellular carcinoma

    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.

  • 新型冠状病毒感染伴发癫痫及其发病机制与脑电图改变

    新型冠状病毒感染(Corona virus disease 2019,COVID-19)是一种由冠状病毒(SARS-CoV-2)导致的新型传染性疾病。关于COVID-19与癫痫之间的关系,有研究认为癫痫发作和COVID-19无明显关系;但也有不少学者认为,癫痫发作是COVID-19的继发症状,甚至是早期症状。COVID-19患者中癫痫发作发生率为0.08%~1.9%。COVID-19出现癫痫发作的直接发病机制是,SARS-COV-2能够直接进入并感染中枢神经系统,引起脑膜炎和脑炎,从而引起癫痫发作。间接发病机制包括:中枢神经系统炎症(细胞因子风暴)、血-脑屏障的破坏、凝血异常、脑卒中、线粒体功能异常、电解质紊乱。新发作和频发癫痫发作的患者可能导致预后更差,死亡率更高。COVID-19伴发癫痫患者中脑电图(Electroencephalogram,EEG)改变的主要表现为:基本节律不同程度的慢化、节律性慢活动、癫痫样放电(包括周期性放电和散在性棘波、尖波等)。癫痫患者EEG的异常部位主要分布在额叶,然而,异常EEG表现并无特异性。

  • Role of tumor associated macrophage in primary liver cancer and its related therapeutic application

    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.

  • Mechanism of immune checkpoint inhibitors related adverse events

    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.

  • Research progress on the mechanism of iron death on blood retinal barrier in autoimmune uveitis

    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.
