Objective To discuss the features of MRI and molybdenum target X-ray in mammary primary non-Hodgkin's lymphoma.Methods 3 cases of mammary primary non-Hodgkin's lymphoma were studied.The features of MRI and molybdenum target X-ray werecollected and analyzed(all 3 cases had molybdenum target X-ray in MLO site and CC site,one had MRI image).Results All 3 caseslesions were in single side,one case had two lesions in one side.The diameter of all the lesions were more than 3cm.The lesion presented as iso-or slight hyperdensity shadow,and related to breast tissue and density was hemogeneous.The tumor was irregular but no bristle andcalcification.There was no skin and nipple involved in superficial of mammary gland.In T_1WI showed even low signal.In T_2WI showedeven little high or equal signal.Intensity was hemogeneous and obvious.The curve of time-signal intensity was platform pattern.Conclusion The features of MRI and molybdenum target X-ray in mammary primary non-Hodgkin's lymphoma are characteristic and helpful for deciding correct therapy plan.

Objective To explore the distribution of age,reasons for treatment,risk factors,and causes of vulvovaginitis in prepubertal girls.Methods A total of 4 214 prepubertal girls with vulvovaginitis who were admitted to the Girl's Sub-department,Zhongshan Boai Hospital from January 2010 to June 2013 was reviewed retrospectively.All clinical data were from medical records with files.Results Atotalof1 587 patients (37.7%) was0to1 years old,954 (22.6%) > 1 to3 years old,1 289 (30.6%) > 3 to 7 years old,and 384 (9.1%) > 7 years old.Many risk factors were associated with vaginitis,including poor hygiene (2 924 girls; 69.4%),allergies and exposure to allergens (875 girls; 20.8%).Most common reason for treatment was a referral from physical examination accounting for 919 girls (21.8%),followed by vaginal secretions 812 girls (19.3%).The causes of vulvovaginitis of all patients were evaluated,1 771 of which (42.0%) were nonspecific vulvovaginitis,1 309 (31.1%) labial adhesions,375 (8.9%) bacterial vulvovaginitis,266 (6.3%) allergic vulvovaginitis,and 266 (6.3%) affective leg rubbing action.Conclusions Prepubertal vulvovaginitis occurred mainly in infancy and preschool.Floating population was common.They were caused by many risk factors including poor hygiene,allergies,poor urination habits,etc.The most common causes of vulvovaginitis were nonspecific vulvovaginitis and labia adhesion,yet allergies and affective leg rubbing action were the more common causes of recurrent vulvovaginitis.We propose that focusing on girls' reproductive health,timely treating allergic and crossing rub legs and other diseases would help reduce the prevalence of vulvovaginitis in the prepubertal girls.

A real time PCR assay for the detection of Vibrio parahaemolyticus in seafood samples was developed using a novel specific target and a competitive internal amplification control (IAC). The specificity of this assay was evaluated using 390 bacterial strains including V. parahaemolyticus, and other strains belonging to Vibrio and non-Vibrio species. The real time PCR assay unambiguously distinguished V. parahaemolyticus with a detection sensitivity of 4.8 fg per PCR with purified genomic DNA or 1 CFU per reaction by counting V. parahaemolyticus colonies. The assays of avoiding interference demonstrated that, even in the presence of 2.1 μg genomic DNA or 10(7) CFU background bacteria, V. parahaemolyticus could still be accurately detected. In addition, the IAC was used to indicate false-negative results, and lower than 94 copies of IAC per reaction had no influence on the detection limit. Ninety-six seafood samples were tested, of which 58 (60.4%) were positive, including 3 false negative results. Consequently, the real time PCR assay is effective for the rapid detection of V. parahaemotyticus contaminants in seafood.
