Objective To investigate the clinical features of of patients with Staphylococcus aureus blood-stream infection and risk factors for septic shock.Methods A total of 51 patients diagnosed with Staphylococ-cus aureus bloodstream infection in the hospital from January 2018 to March 2023 were enrolled in the study.According to whether the patients developed septic shock,they were divided into septic shock group and non-septic shock group.The clinical data of the patients were collected,and the clinical laboratory indicators were detected on the day of blood culture samples were collected.Bacteria isolated from blood culture specimens of patients were identified and tested for drug sensitivity.The clinical data and clinical laboratory test indicators of the two groups were compared.Multivariate Logistic regression was used to analyze the independent risk factors of septic shock in patients with Staphylococcus aureus bloodstream infection.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of clinical laboratory test indicators for septic shock in patients with Staphylococcus aureus bloodstream infection.Results Septic shock occurred in 12 of 51 patients,with an incidence of 23.5％.The proportion of patients with diabetes,gouty arthritis,the proportion of patients with long-term glucocorticoid use,the proportion of patients with respiratory tract in-fection,the proportion of patients who died,and the hospitalization cost in the septic shock group were higher than those in the non-septic shock group,and the differences were statistically significant(P＜0.05).Long-term glucocorticoid use was an independent risk factor for septic shock in Staphylococcus aureus bloodstream infection(P＜0.05).The combination of C-reactive protein(CRP),albumin(Alb),neutrophil/lymphocyte ratio(NLR)and procalcitonin(PCT)had high value in predicting septic shock in patients with Staphylococ-cus aureus bloodstream infection,and the area under the ROC curve was 0.983.Conclusion Long-term use of glucocorticoids can lead to an increased risk of septic shock in patients with Staphylococcus aureus blood-stream infection.The combined detection of CRP,Alb,NLR and PCT has a higher predictive value than single detection for septic shock in patients with Staphylococcus aureus bloodstream infection.

Chronic atrophic gastritis （CAG） is a common and intractable disease in the digestive system characterized by the reduction or disappearance of gastric mucosal glands. The intestinal metaplasia or dysplasia in CAG is called precancerous lesion， which greatly increases the risk of cancerization. Dysactivation of nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） inflammatory corpuscles can release a large number of inflammatory factors， induce inflammatory cascade reactions， and participate in the process of many diseases. As reported， the dysactivation of NLRP3 inflammatory corpuscles can cause long-term chronic inflammatory infiltration of gastric mucosa and induce the development of CAG. Mitochondrial dysfunction plays an important role in the activation of NLRP3 inflammatory corpuscles. The accumulation of reactive oxygen species （ROS） produced by mitochondrial dysfunction is the key to activating NLRP3 inflammatory corpuscles. Professor LIU Youzhang put forward the theory of "spleen-mitochondrion correlation"， which holds that the spleen mainly transports water and grains， generates qi and blood， transports nutrients to the whole body， and supplies energy and materials needed by the body. Adenosine triphosphate （ATP） generated by mitochondria through the circulation of tricarboxylic acid is the main energy source of the human body. The view that both of them serve as human energy processing plants coincides in terms of physiology. Pathologically， spleen deficiency is associated with mitochondrial oxidative phosphorylation dysfunction. Pathological products such as dampness， turbidity， phlegm， and blood stasis due to failure in transportation because of spleen deficiency are consistent with metabolites generated by mitochondrial dysfunction. Based on the theory of "spleen-mitochondrion correlation"， this study discussed the pathogenesis of CAG in traditional Chinese medicine （TCM）， analyzed the relationship between NLRP3 inflammatory corpuscles and the pathogenesis of CAG， and proposed that the activation of NLRP3 inflammatory corpuscles by mitochondrial dysfunction was the modern biological basis of the pathogenesis of spleen deficiency in CAG. The spleen-strengthening method may be related to improving the mitochondrial function and inflammatory response of patients with CAG and alleviating the damage of gastric mucosa， providing a new idea for TCM in the prevention and treatment of CAG.
