  • 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.

  • 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。

  • The pathogenesis, diagnosis and treatment progress of coronavirus disease 2019 complicated by renal injury

    With the in-depth understanding of the severe acute respiratory syndrome coronavirus 2, it has been found that the virus not only causes serious damage to the human respiratory system, but also damages the kidney system, which can be manifested as acute kidney injury, and in severe cases, renal failure can occur. Patients with coronavirus disease 2019 and chronic kidney disease are at higher risk of worsening their condition and even death. Therefore, early recognition and intervention of renal injury is particularly important for prognosis. In this paper, the clinical data of renal injury in patients with coronavirus disease 2019 were reviewed, and the possible pathogenesis, incidence, clinical features, diagnosis and treatment were proposed for reference in clinical decision-making.

  • Old Drug, New Tricks: Metformin in Treatment of Patients with Type 2 Diabetes Mellitus Complicated with Liver Cancer

    ObjectiveTo understand the role of metformin on reducing incidence of type 2 diabetes mellitus (T2MD) patients complicated with liver cancer. MethodThe related literatures of metformin treated patients with T2MD complicated with liver cancer at home and abroad in recent years were reviewed. ResultsA large number of epidemiological and clinical data showed that the metformin might prevent the occurrence of the T2MD patients complicated with liver cancer, its mechanism was mainly inhibited the proliferation of hepatoma cells through the ATM-LKB1-AMPK-mTOR pathway, PI3K/Akt/mTOR pathway, or miRNA. The current controversy was the authenticity of the data, the influencing factors included the aging problem and characteristics of metformin user. The prospective study design rigorous remained to be clarified. ConclusionMetformin could reduce the incidence of T2MD patients complicated with liver cancer, and could inhibit the growth of liver cancer cells, which provides a new way of thinking for the comprehensive treatment of liver cancer.

  • Research progress of role of Helicobacter pylori on oncogenesis and progression of pancreatic cancer

    Objective To study effects of Helicobacter pylori on oncogenesis and progression of pancreatic cancer. Method The current literatures on the relationship between the Helicobacter pylori and the pancreatic cancer were collected and reviewed. Results The Helicobacter pylori infection might play a role in the development of the pancreatic cancer. The infection rate of the Helicobacter pylori in the patients with pancreatic cancer is higher than that of the healthy controls; furthermore, in the patients with Helicobacter pylori antibody positive, the infection rate of the Helicobacter pylori in the cytotoxin-associated gene A-negative strains of Helicobacter pylori is significantly higher than that of the healthy controls. Conclusions Helicobacter pylori infection is related to occurrence and development of pancreatic cancer. Specific mechanism is still not clarified and further research is need to study.

  • 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.

  • 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。
