Sepsis is a prevalent form of acute and critical illness encountered in intensive care unit (ICU), characterized by a high mortality and cognitive impairments among survivors. The pathogenesis of sepsis primarily involves immune dysfunction and excessive oxidative stress. Consequently, immune modulation, along with anti-inflammatory and antioxidant strategies, has emerged as a focal point in the treatment of sepsis. Recent studies have highlighted the potential of B vitamins to modulate immune cell activity while exhibiting anti-inflammatory and antioxidant properties, thereby garnering significant interest regarding their therapeutic efficacy in sepsis management. Notably, vitamin B2 and vitamin B9 are recognized for their roles in regulating immune cells and facilitating immune modulation. Vitamins B1, B2, B6, and B12 demonstrate notable anti-inflammatory and antioxidant effects. Specifically, vitamin B1 exerts its antioxidant influence through the regulation of the tricarboxylic acid cycle while mitigating inflammation by modulating inflammatory factor levels in septic patients—an application that has been integrated into clinical practice. The anti-inflammatory action of vitamin B2 is achieved through the regulation of inflammatory mediators in septic patients alongside reducing inflammasome activation within macrophages. Vitamin B6 contributes to both anti-inflammatory responses and antioxidative defense by scavenging free radicals and enhancing the production of antioxidant enzymes. Furthermore, vitamins B1, B6, B9, and B14 have shown promise in improving neurocognitive function among individuals suffering from sepsis. This article reviews the immunomodulatory functions as well as the anti-inflammatory and antioxidative effects associated with various B vitamins while exploring their applications within sepsis treatment to propose novel therapeutic avenues.

Objective:To explore the path of standardized training and quality supervision for geriatric nursing assistants basing on the three-way linkage of "hospital, government and market".Methods:From January 2019 to December 2020, we conducted standardized training and management for geriatric nursing assistants in 24 nursing institutions for the aged in Mianyang, Sichuan Province in batches. Through the three-way linkage of "hospital, government and market", the whole-process management mode of "standardized training of geriatric nursing assistants, one-to-many tracking service for three months after the training, and service quality supervision of nursing institutions for the aged" has been established. The theoretical and operational achievements of nursing staff before and after training, the service quality of nursing home and the incidence of adverse events before and after the implementation of the project were observed and compared.Results:From 2019 to 2020, a total of 224 geriatric nursing assistants were trained in five sessions. There were statistical differences in the theoretical and operational scores before and after the training ( t=-72.494, -26.150; P<0.01) . 13 nursing institutions participating in the training in 2019 were selected to compare the service quality before and after the project implementation, the difference was statistically significant ( t=-14.575, P<0.01) , and the incidence of nursing adverse events decreased (χ 2=-7.913, P<0.01) . Conclusions:The mode of geriatric nursing assistants training and quality supervision based on the three-way linkage of "hospital, government, market" is conducive to giving full play to the administrative function of the government and the professional function of the hospital, effectively integrating resources and improving the quality of geriatric nursing service in the region.
