Objective To evaluate the value of ultrasound in diagnosing ductal carcinoma in situ (DCIS). Methods The sonographic characteristics of 12 DCIS which were confirmed by pathology were analyzed retrospectively. Results The ultrasound image of DCIS could be divided into four types;the solid mass nodule, mammary dysplasia, mix mass nodule, the dilated duct type. Micro calcification had high incidence rate. Ultrasonic diagnosis accordance rate was 50.0 %. On molybdenum target mammograms, the tumor appeared as a cluster of calcified spots in 8 cases, and the accuracy rate of diagnosis of was 66.7 %.Conclusion There are no typical characters of DCIS in ultrasound image. However, some characteristics are suggestive and can help to differentiate them from the benign tumors, such as small nodule, irregular shape,obscure boundary, and microcalcification. When sonography combine with molybdenum target mammography,the accuracy rate of diagnosis will be improved.

Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .
