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.

The clinical information of stroke patients (n = 53 793) were extracted from the Yidu cloud big data server system of the Second Affiliated Hospital of Dalian Medical University from January 1, 2001 to July 31, 2023. Combined with the results of single factor screening and the opinions of experts with senior professional titles in neurology, the input variable was determined, and the output variable was the National Institutes of Health Stroke Scale (NIHSS) representing the severity of the disease at admission. Python 3.7 was used to build DeepFM algorithm model, and five data mining models including Logistic regression, CART decision tree, C5.0 decision tree, Bayesian network and deep neural network (DNN) were built at the same time. The original data were randomly divided into 80% training set and 20% test set, which were used to train and test the models, adjust the parameters of each model, respectively calculate the accuracy, sensitivity and F-index of the six models, carry out the comprehensive comparison and evaluation of the model.

The patients were divided into survival and death groups based on their 28-day prognosis. The factors influencing 28-day mortality were analyzed, and routine laboratory data were used to develop a nomogram model for predicting the risk of 28-day mortality in septic shock patients.
