RESUMEN
Objective To explore the clinical characteristics of systemic disseminated infection caused by Mycobacterium fortuitum (M.fortuitum), and improve the diagnostic rate and understanding of the disease.Methods One case of systemic disseminated M.fortuituminfection was reported, and analyzed in combination with relevant literatures.Results Patient was with multiple systemic involvement (including lung, lymph node, skin, joint), lymph node tissue culture was positive for M.fortuitum, patient was given clarithromycin+levofloxacin+linezolid for treatment, disease was remitted.Conclusion Systemic disseminated M.fortuituminfection is rare, and patient with GATA2 deletion and IFN-γautoantibody may be a potential mechanism, diagnosis is mainly based on pathological morphology and microbiological detection, but positive rate is low, diagnosis is difficult.
RESUMEN
OBJECTIVE@#To observe the effect of Xinglong Pingchuan recipe (XLPCR) on interleukin-5 (IL-5), superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) in mouse asthma models, and to explore its mechanism in treating asthma.@*METHODS@#The mouse asthma models were established by sensitization and challenge with ovalbumin (OVA). The asthma model was treated with XLPCR. At last, the number of white blood cells and eosinophil was counted, and the concentrations of inflammation factors such as IL-5, SOD, GPx, and MDA in the serum or the lung tissue of each mouse were detected.@*RESULTS@#Compared with the asthmatic group, the number of eosinophil in the XLPCR group decreased significantly (P 0.05, respectively). On the other hand, the concentration of MDA in the XLPCR group was significantly lower than that of the asthmatic group (P < 0.05).@*CONCLUSION@#XLPCR might inhibit the airway inflammation by decreasing the IL-5 level and adjusting the balance of oxidants/antioxidants.
