RESUMO
Objective@#To analyze the subjective and objective misdiagnostic reasons of brucellosis in Suzhou City.@*Methods@#The clinical data of inpatients with brucellosis from the department of infectious diseases, the First Affiliated Hospital of Soochow University from 2016 to 2018 were collected. The main onset methods, the first consultation department, the diagnosis and treatment process, and the main diagnosis were analyzed. Simultaneously, a questionnaire survey was conducted among doctors from different departments in Suzhou City. To investigate the knowledge and diagnosis of brucellosis by electronic questionnaire, and analyze the results.@*Results@#Totally 24 brucellosis cases were collected. Fever (13 cases, 54.17%), lumbago/arthralgia (6 cases, 25.00%) or both (3 cases, 12.50%) were the main initial symptoms, while a patient with fever, arthralgia and orchitis(1 case, 4.17%) and another with purpura (1 case, 4.17%) were also admitted. The 24 patients were distributed among 10 different departments, in which the department of infectious diseases (6 cases, 25.00%) and orthopedics (5 cases, 20.83%) dominated. Brucellosis was considered in only 2 patients (8.33%) before pathogen results, and the main suspected diagnosis were malignant hematopathy/lymphoma (7 cases, 29.17%), sepsis (5 cases, 20.83%), and tuberculosis (4 cases, 16.67%). Totally 124 questionnaires were collected and analyzed. We divided them into 2 groups: department of infectious diseases (52/124, 41.94%) and other departments (72/124, 58.06%). The proportion of answer "yes" for the question Suzhou is the epidemic area of brucellosis, question whether brucellosis is considered in suspected patients, question whether the epidemiology is collected and question how and where to conduct the serological test was 38.71% (48/124), 32.26% (40/124), 53.23% (66/124) and 29.84% (37/124), respectively. The positive answer in the department of infectious diseases (24/52, 46.15%) was significantly higher than those of others (16/72, 22.22%, χ2=7.913, P < 0.05). The respondents thought the serological test could not be conducted, because of that the non-pasture doctors were not familiar with the test procedure, which was complex (93/124, 75.00%) and the disease was not considered (85/124, 68.55%). And the respondents thought measures helpful to reduce misdiagnosis should include setting up serological test or simplifying the procedure (96/124, 77.42%), massed learning organized by related administrations (95/124, 76.61%) and learning by books, papers and classes (72/124, 58.06%).@*Conclusion@#There is obvious clinical misdiagnosis of brucellosis in Suzhou City, which may be caused by Suzhou doctors not paying enough attention to brucellosis, being unfamiliar with the inspection process and complicated inspection process.

RESUMO
Objective To explore the diagnostic value of MR elastography and diffusion?weighted imaging in patients with liver fibrosis in the context of chronic hepatitis B. Methods Twenty?four patients with chronic hepatitis B, whose course of liver disease was more than 6 months and hepatitis B surface antigen was positive, were prospectively enrolled in the First Affiliated Hospital of Soochow University from July to December 2017. All of the patients underwent abdominal transient elastography (TE), routine MRI, magnetic resonance elastography (MRE) and DWI examination, TE and MRI were performed within one week. TE liver stiffness was measured, the MRE liver stiffness and ADC value were measured on MR imagings. All patients were divided into three groups: mild and non fibrosis (F0 to 1), significant fibrosis(F2 to 3) and cirrhosis (F4), according to the recommended standard of FibroTouch. Correlation between TE liver stiffness, MRE liver stiffness and ADC values were identified by using Spearman correlation test. The difference of the MRE liver stiffness and ADC value among the three groups was tested using independent sample t test. The overall predictive ability of MRE and DWI in assessment of liver fibrosis and cirrhosis was analyzed by constructing ROC curve. Results TE and MRI were successfully performed in all subjects, and the image quality was good. The MRE liver stiffness in mild and non fibrosis, significant fibrosis and cirrhosis was (2.32±0.31),(3.43±1.05),(4.77±0.68) kPa with statistically significant difference(F=61.690, P<0.01). The ADC values in three groups were (1.31 ± 0.14)×10-3, (1.23 ± 0.15)×10-3,(1.22±0.12)×10-3mm2/s without significant difference(F=1.074,P=0.360). The TE liver stiffness in three groups was (5.61±1.05),(9.56±0.57),(17.25±3.55)kPa, respectively, there was significant correlation between the MRE liver stiffness and the TE liver stiffness(t=0.858, P<0.01), but no significant correlation between the TE liver stiffness and the ADC value was found (r=-0.326,P=0.120). The area under ROC of MRE liver stiffness in diagnosing liver fibrosis grade (≥F2 and F4) was 0.96 and 1.00 respectively, while the AUC of ADC value was less than 0.70, which were 0.67 and 0.62 respectively. Conclusion MRE is a non?invasive promising tool for assessing liver fibrosis with chronic hepatitis B, while DWI has limited role.
