The unmanned vehicle on-ramp merging model based on AM-MAPPO algorithm.

In response to the issues of low merging success rates and poor safety in the on-ramp merging scenario within autonomous driving, we propose an on-ramp merging model for unmanned vehicles based on the Multi-Agent Proximal Policy Optimization (MAPPO) algorithm. Firstly, we introduce an Action-Mask (AM) to prevent the sampling of invalid actions during merging, thus enhancing safety by ensuring only valid actions are considered. Secondly, we incorporate noise advantage values to encourage unmanned vehicles to thoroughly explore the environment and avoid being trapped in local optimal solutions.

Erythropoietin-mediated IL-17 F attenuates sepsis-induced gut microbiota dysbiosis and barrier dysfunction.

Septic gut damage is critical in the progression of sepsis and multiple organ failure, characterized by gut microbiota dysbiosis and epithelium deficiency in the gut barrier. Recent studies highlight the protective effects of Erythropoietin (EPO) on multiple organs. The present study found that EPO treatment significantly alleviated the survival rate, suppressed inflammatory responses, and ameliorated intestine damage in mice with sepsis.

Dynamic monitoring of circulating CD8 T and NK cell function in patients with septic shock.

Background: Septic shock is a great threat to human life. Our aim is to explore the immune status and dynamic changes of circulating cytotoxic cells in septic shock patients.

Methods: Forty-eight septic shock patients (9 non-survivors and 39 survivors) and 30 healthy controls (HCs) were enroled in our study.

IL-6 and IL-10 Closely Correlate with Bacterial Bloodstream Infection.

Background: Given the high mortality of bacterial bloodstream infections (BSI), blood culture results do not meet clinical needs timely due to being time-consuming and having low positive rate. Whether we can identify the severity and type of bacterial infections by cytokines is a controversial issue.

Objective: To investigate the dynamic change of cytokines in BSI.

CoQ10 ameliorates mitochondrial dysfunction in diabetic nephropathy through mitophagy.

The molecular signaling mechanisms of Coenzyme Q10 (CoQ10) in diabetic nephropathy (DN) remain poorly understood. We verified that mitochondrial abnormalities, like defective mitophagy, the generation of mitochondrial reactive oxygen species (mtROS) and the reduction of mitochondrial membrane potential, occurred in the glomerulus of db/db mice, accompanied by reduced PINK and parkin expression and increased apoptosis. These changes were partially reversed following oral administration of CoQ10.

[The correlation between ICAM-1 gene K469E polymorphism and coronary heart disease].

Objective: To investigate the correlation between intercellular adhesion molecule1 (ICAM1) gene K469E polymorphism and coronary heart disease(CHD) in Han Chinese population.

Methods: Using the methods of polymerase chain reaction-restrictive fragment length polymorphism (PCR-RFLP), 173 CHD patients and 141 controls were analyzed for the polymorphism, genotype and allele distribution of ICAM1 gene K469E.

Results: The distribution of ICAM1 genotypes was in Hardy-Weinberg equilibrium.
