  • Research progress on the correlation between gender differences and the incidence of knee osteoarthritis

    Knee osteoarthritis (KOA) is one of the common degenerative joint diseases, which is more common in the middle-aged and elderly population. It shows significant gender differences, with a significantly higher incidence rate in women than in men, seriously affecting the quality of life of patients. However, there are few research reports on the correlation between gender differences and the incidence of KOA both domestically and internationally. Therefore, this article will summarize and analyze the potential causes of gender differences related to the incidence of KOA from five aspects: hormone levels, anatomical biomechanical characteristics, genes, obesity, and exercise-muscle factors. Through a comprehensive review of research progress, the aim is to provide a theoretical basis for gender based personalized treatment of KOA in clinical practice.

  • Progress of pathogenesis and genetics of alcohol-induced osteonecrosis of femoral head

    ObjectiveTo review the research progress of pathogenesis and genetics of alcohol-induced osteonecrosis of the femoral head (AIONFH). MethodsThe relevant domestic and foreign literature in recent years was extensively reviewed. The pathogenesis, the relationship between gene polymorphism and susceptibility, the related factors of disease progression, and the potential therapeutic targets of AIONFH were summarized. ResultsAIONFH is a refractory orthopedic disease caused by excessive drinking, seriously affecting the daily life of patients due to its high disability rate. The pathogenesis of AIONFH includes lipid metabolism disorder, endothelial dysfunction, bone homeostasis imbalance, and et al. Gene polymorphism and non-coding RNA are also involved. The hematological and molecular changes involved in AIONFH may be used as early diagnostic markers and potential therapeutic targets of the disease. ConclusionThe pathogenesis of AIONFH has not been fully elucidated. Research based on genetics, including gene polymorphism and non-coding RNA, combined with next-generation sequencing technology, may provide directions for future research on the mechanism and discovery of potential therapeutic targets.

  • 慢性间歇缺氧引起高血压的发病机制

    阻塞性睡眠呼吸暂停低通气综合征( OSAHS)是临床常见疾病。高血压、肺动脉高压、冠心病、心力衰竭、心律失常、猝死及脑血管疾病等都与OSAHS 存在密切相关性, 但对于OSAHS 所致全身性疾病的发病机制尚未完全阐明。已知慢性间歇低氧( chronic intermittent hypoxia, CIH) 和睡眠结构紊乱是OSAHS 的主要病理生理特征, 因而通常将啮齿类动物反复暴露于短暂间歇低氧环境中来模拟阻塞性睡眠呼吸暂停( obstructive sleep apnea, OSA) 的低氧血症, 并借此探讨OSAHS 所致疾病的机制[ 1 ] ,尤其是与高血压的相关性。近年来, 对于间歇低氧( intermittent hypoxia, IH) 导致这些疾病发生的分子机制取得诸多进展, 包括神经系统、循环系统、炎症介质和转录因子等方面。

  • 神经炎症在婴儿痉挛发病机制中的研究进展

    婴儿痉挛(Infantile spasms,IS)是一种独特的,并有年龄依赖性的婴儿早期癫痫性脑病。具有发病年龄早、发作形式特殊、进行性认知损害、脑电图呈高峰失律等特征。其病因复杂、多样,发病机制尚未明确,治疗方面仍存在困难,大多遗留智能缺陷等后遗症。癫痫的发生与神经组织微环境中增加的强烈而持续的炎症状态相关,受损神经元组织中炎症细胞和分子的激活、分解调节障碍是癫痫发展的关键因素,炎症可能起源于中枢神经系统,或通过血脑屏障的破坏从全身循环获得。同时癫痫也可能激活促炎通路,导致神经炎症的发生。本文对近年神经炎症通路在 IS 发病机制中的作用研究进行综述,通过总结遗传学进展揭示了许多参与 IS 发病机制的基因,包括直接或间接参与炎症的基因,同时得到临床和 IS 动物模型的研究支持。了解 IS 发生发展过程中炎症的神经生物学将有助于开发新的生物标志物,以便更好地筛选高危患者,为探索 IS 治疗新靶点提供方向。

  • 癫痫合并认知功能障碍研究进展

    认知功能障碍是癫痫常见共病, 严重影响患者生活质量。近年来日益受到重视, 其机制及影响因素复杂, 目前尚缺乏特异有效的治疗手段, 且治疗效果欠佳。因此阐明癫痫认知功能障碍的发病机制对于开发新的治疗药物具有重要意义。癫痫合并认知功能障碍的原因可能是癫痫病因、发作本身、间期放电、神经网络异常、抗癫痫药物、手术等多种因素共同作用的结果, 现将对癫痫合并认知功能障碍的机制及影响因素做一综述。

  • Research progress on the etiology and pathogenesis of spina bifida

    ObjectiveTo review the research progress on etiology and pathogenesis of spina bifida. MethodsBy consulting relevant domestic and foreign research literature on spina bifida, the classification, epidemic trend, pathogenesis, etiology, prevention and treatment of it were analyzed and summarized. ResultsSpina bifida, a common phenotype of neural tube defects, is classified based on the degree and pattern of malformation associated with neuroectodermal involvement and is due to the disturbance of neural tube closure 28 days before embryonic development. The prevalence of spina bifida varies greatly among different ethnic groups and regions, and its etiology is complex. Currently, some spina bifida patients can be prevented by folic acid supplements, and with the improvement of treatment technology, the short-term and long-term survival rate of children with spina bifida has improved. ConclusionThe research on the pathogenesis of spina bifida will be based on the refined individual information on exposure, genetics, and complex phenotype, and will provide a theoretical basis for improving prevention and treatment strategies through multidisciplinary cooperation.

  • 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.

  • 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。

  • Research progress on the correlation between mitochondrial pathway and epilepsy

    Epilepsy is a complex disease spectrum, because of long-term recurrent seizures and seriously affect the quality of life of patients, it is of great significance to explore the pathogenesis of epilepsy and actively seek new therapeutic targets. In this paper, the pathogenesis of epilepsy related to mitochondrial pathway was discussed from the aspects of energy depletion, oxidative stress damage, impaired calcium homeostasis, increased glutamic acid release, mitochondrial DNA mutation, Coenzyme Q10 deficiency, abnormal mitochondrial movement and change, and relevant therapeutic ideas were proposed. This paper shows that mitochondrial function affects the onset of epilepsy from various ways. Further understanding of the relationship between mitochondria and the onset of epilepsy is beneficial to find new therapeutic targets and develop new therapies beyond the control of epilepsy.
