The coronavirus disease 2019 (COVID-19) epidemic has a tremendous impact on the countries around the world since the outbreak in December 2019. From December 2022, with the loosening of domestic epidemic control policies, the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rose significantly and reached to its epidemic peak in the majority of the cities in China, which further overwhelmed our medical care system. The cardiac surgery departments in China lack the experience in conducting work under the COVID-19 pandemic. In this paper, we summarize the main topics that might be faced during the pandemic by reviewing the previous related literatures, which included: the cardiac surgery volume trends, the impact of SARS-CoV-2 infection on the prognosis of cardiac surgery, the timing of cardiac surgery and the surgical strategy should be modified, and possible recommendations for the manager or governors during the pandemic, so as to outline a path forward for cardiac surgery for the near future.
ObjectiveTo summarize a comprehensive overview of the mechanism of ferroptosis and its associated microRNAs in the occurrence and development of hepatocellular carcinoma (HCC), and to offer novel insights and potential avenues for tumor marker screening and targeted treatment in clinical hepatocellular carcinoma patients. MethodThe literatures on the basic and clinical application research of ferroptosis and related microRNA in the occurrence, development and prognosis of HCC at home and abroad in recent years were reviewed and summarized, and the research progress of microRNA regulating ferroptosis in HCC was summarized. ResultsMicroRNA, a type of non-coding small RNA, had the ability to regulate gene expression at the post-transcriptional and translational levels. It held promising potential in the diagnosis and treatment of HCC. Ferroptosis, on the other hand, was a form of cell death triggered by iron-dependent lipid peroxidation. It played a crucial role in the development of HCC. A series of miRNAs related to ferroptosis might act as HCC growth regulators to regulate the growth of cancer cells, or reverse the drug resistance of cancer cells, thereby promoting or inhibiting the occurrence and progression of HCC. ConclusionsMicroRNA can regulate the occurrence and development of HCC through the ferroptosis pathway and may become tumor markers for the early diagnosis of HCC. Additionally, microRNA may also serve as a related therapeutic target and provide a new treatment option for HCC.
