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.
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.
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.
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.
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.
