Effect of down-regulation of let-7c/g on triggering a double-negative feedback loop and promoting restenosis.
Excessive proliferation and migration of vascular smooth muscle cells (VSMCs) are the main causes of restenosis (RS) in diabetic lower extremity arterial disease (LEAD). However, the relevant pathogenic mechanisms are poorly understood. ⋯ These findings indicated the presence of a double-negative feedback loop consisting of Lin28a and let-7c/let-7g, which may be responsible for the vicious behavior of VSMCs in RS.

ReviewResearch progress in the mechanism and treatment of osteosarcoma.
Osteosarcoma (OS) is the most common primary malignant bone tumor that more commonly occurs in children and adolescents. The most commonly used treatment for OS is surgery combined with chemotherapy, but the treatment outcomes are typically unsatisfactory. High rates of metastasis and post-treatment recurrence rates are major challenges in the treatment of OS. ⋯ Previous studies have demonstrated the important role of the bone microenvironment and the regulation of signaling pathways in the occurrence and development of OS. In this review, we discussed the available evidence pertaining to the mechanisms of OS development and identified therapeutic targets for OS. We also summarized the available treatment modalities for OS and identified future priorities for therapeutics research.

Multicenter StudyAssociation between hemoglobin glycation index and 5-year major adverse cardiovascular events: the REACTION cohort study.
The hemoglobin glycation index (HGI) was developed to quantify glucose metabolism and individual differences and proved to be a robust measure of individual glycosylated hemoglobin (HbA1c) bias. Here, we aimed to explore the relationship between different HGIs and the risk of 5-year major adverse cardiovascular events (MACEs) by performing a large multicenter cohort study in China. ⋯ We found a U-shaped correlation between the HGI values and the risk of 5-year MACE. Both low and high HGIs were associated with an increased risk of MACE. Therefore, the HGI may predict the 5-year MACE risk.

Global and national burden of atherosclerosis from 1990 to 2019: trend analysis based on the Global Burden of Disease Study 2019.
Atherosclerosis-related diseases represent significant health issues among adults globally. Despite their widespread impact, comprehensive data concerning the global and national burden and trends of these diseases remain sparse. Our objective is to examine the trends in the burden of atherosclerosis among adults from 1990 to 2019 at both global and national levels. ⋯ From 1990 to 2019, there was an overall increasing trend in the global incidence of all three clinical manifestations of atherosclerosis. Between 1990 and 2019, both the mortality rate and DALYs for IHD and ischemic stroke declined across all age groups. Overall, the burden of atherosclerosis-related diseases has not significantly decreased and even shows signs of trending upward. These findings strongly suggest that despite some progress made, efforts to control atherosclerosis diseases globally need to be intensified.
