Objective To present the distinction on clinical features,laboratory features,treatment schemes between the patients with and without brucellar epididymo-orchitis,and to provide a theoretical basis for clinical diagnosis and treatment.Methods A retrospective analysis of 223 male patients with brucellosis in the First Hospital of Jilin University from June 2010 to November 2016 was carried out.A comparative analysis of the clinical and laboratory features of 22 patients with epididymo-orchitis and 201 cases without epididymo-orchitis was done.The SPSS 23.0 software was used to analyze the statistical results,P ＜ 0.05 was defined as statistically significant.Results Epididymo-orchitis occurred in 9.87％ (22/223) of all male patients with brucellosis.The median ages of patients with and without epididymo-orchitis were 35.5 and 42.0 years old,respectively,the difference was not statistically significant (Z =1.323,P ＞ 0.05).Cases with and without epididymo-orchitis of brucellosis with fever [90.9％ (20/22) vs 69.2％ (139/201)],chills [54.4％ (12/22) vs 28.9％ (58/201)],hepatomegaly [22.7％ (5/22) vs 3.5％ (7/201)],abdominal symptoms [59.1％ (13/22) vs 17.4％ (35/201)],and urinary tract infection symptoms [31.8％ (7/22) vs 3.5％ (7/201)],the differences were statistically significant (x2 =4.586,6.076,14.424,20.392,27.059,all P ＜ 0.05).The medians of white blood cell (WBC) count (7.9 × 109/L),erythrocyte sedimentation value (ESR,38.0 mm/h),and aspartate aminotransferase (AST,110.0 U/L) in brucellosis with epididymo-orchitis were higher than those without epididymo-orchitis (5.1 × 109/L, 30.0 mm/h,73.8 U/L),the differences were statistically significant (Z =2.239,2.064,2.762,all P ＜ 0.05).All brucellosis patients with epididymis-orchitis were treated with antibiotics for 8 weeks.The defervescence time was 4.5 days,the time of pain relief was 3.9 days,21 patients were cured,and only Ⅰ patient relapsed.Conclusions Epididymo-orchitis is a common complication of brucellosis.Brucellar epididymo-orchitis is usually characterized with a severe acute clinical presentation,which needs timely diagnosis.Combination of antibiotics treatment for 8 weeks in brucellosis patients with epididymis-orchitis is effective.

Objective To investigate the effect of propofol on ketamine-induced cognitive dysfunction and neuronal apoptosis in hippocampus in aged rats. Methods Thirty-two male SD rats aged 18-24 months weighing 380-470 g were randomly divided into 4 groups ( n = 8 each) :control group (group C);propofol group (group P);ketamine group (group K) and propofol + ketamine group (group PK). Propofol 30 mg·kg-1·h-1 or/and ketamine 40 mg· kg-1·h-1 were infused for 2 h once a day for 7 consecutive days. After the last day of drug administration cognitive function was assessed using Morris water maze (escape latency and the number of animals' swimming across the platform). The animals were sncrificed after water naze test and their hippocampi were removed for determination of neuronal apoptosis (by TUNEL) and caspase-3 expression (by immuno-histochemistry) in hippocampal CA1 region. Results There was no significant difference in escape latency and the number of the animals,swimming across the platform, the neuronal apoptotic rate (the number of apoptotic neurons/the number of total neurons) and caspase-3 expression between group C and P. In group K and PK the escape latency was prolonged,the number of animals' swimming across the platform was decreased, neuronal apoptotic rate increased and the caspase-3 expression up-regulated as compared with group C. The ketamine-induced changes were significantly attenuated by coadministration of propofol in group PK. Conclusion Coadministration of propofol can ameliorate ketamine-induced cognitive dysfunction and hippocampal neuronal apoptosis.
