OBJECTIVES@#To investigate the clinical characteristics of patients with listeriosis and to provide a basis for diagnosis, treatment, prevention and control of hospital infection.@*METHODS@#A total of 10 inpatients, who suffered from the listeriosis in Xiangya Hospital, Central South University from January 2013 to June 2019, were retrospectively collected for this study. The characteristics of the patients' age, gander, basic information, case type, clinical manifestations, first consultation department, days of diagnosis, infection indicator, specimen type, results of drug sensitivity, treatment plan, hospital infection or not, outcome, follow-up data were analyzed.@*RESULTS@#Two cases were pregnant women and other were non-pregnant adults among 10 patients with listeriosis. Among them, there were 3 cases with hospital acquired infection. The age of patient onset was 27-71 years old, and the time from onset to diagnosis was 5-36 days. Five cases had fever, and other 5 cases had not fever. There were headache, fatigue, local pain, and other specialized symptoms in the 10 patients.The white blood cell count,the neutrophil ratio, the inflammatory index C-reactive protein, the procalcitonin were all increased, and the erythrocyte sedimentation was accelerated in the 10 patients.All the patients were sensitive to ampicillin, penicillin G, meropenem, and compound sinomine.@*CONCLUSIONS@#Listeriosis often affects the patients with low immunity, which often leads to misdiagnosis or missed diagnosis in clinic.So early prevention, early diagnosis, and early treatment can reduce mortality; it is important for departments of nosocomial infection management to manage patients' diet for avoiding outbreaks of listeriosis in hospital.

Objective To investigate the usefulness of three-dimensional reconstruction in the preoperative evaluation of the texture of pituitary tumors. Methods Seventy patients with pituitary tumors admitted to our hospital between January 2015 and July 2018 were enrolled in the study. All patients underwent enhanced MRI scanning before surgery. They were classified into the soft group, medium group, and tough group according to the tumor texture. The patient's clinical data, MRI images, and surgery conditions were collected.The Mimics software was used to reconstruct the three-dimensional models of pituitary adenomas. The volume and surface area of different tumor signal groups were calculated and analyzed. In addition, the relationships between tumor size, tumor resection, and postoperative complications were analyzed. Results The three-dimensionally reconstructed model of the pituitary adenoma had a clear outline and was consistent with the tumor area in the MRI images. The calculated average threshold accurately segmented the images. Grouped by the classification of texture, the differences of the proportions of each part were statistically significant (P < 0.01). According to the ordinal polytomous logistics regression analysis, the proportion of the volume of the higher part positively correlated with the tumor texture (P <0.05), and the ratio of the surface area of the medium part to the overall surface area positively correlated with the tumor texture (P < 0.05).Conclusion The use of Mimics software for 3 D reconstruction of preoperative MRI images can accurately predict the tumor texture in pituitary tumors and can provide a basis for the choice of surgical methods.
