Objective To evaluate the sonography features of heptaobiliary involvement of pediatric Langerhans′cell histiocytosis ( LCH) . Methods Nine pediatric patients with LCH confirmed by the clinical presentation ,biochemical tests and pathologic results of our hospital were retrospectively analyzed . Results Eight patients were seen in multi‐system LCH ,while one patient only had liver involved . All patients showed varying hepatomegaly with multiple distributed lesions in ultrasound images . According the lesion distribution features ,they could be classified into three types:central type(6/9) ,peripheral type(1/9) and diffuse type(2/9) . In ultrasonography ,they manifested as linear lesions alongside the central portal veins , multi‐nodular and randomly distributed lesions in liver parenchyma ,or both of them . Eight bile‐duct involved patients behaved with unevenly thicked bile‐duct walls ,stenosis or dilated bile‐ducts ,and even sclerosing cholangitis , some of them with cholelithiasis . Conclusions Pediatric LCH patients with heptobiliary involved are seemed mainly in multi‐system LCH ,while it is rare but possible that pathological Langerhans′cell only infringe on liver and bile‐ducts . The ultrasound imaging findings of pediatric LCH liver infiltration are with characteristic and are helpful for the early diagnosis and clinical procedure .

Objective To explore the imaging features of pediatric splenic primary solitary tumor. Methods The medical imaging appearances of 6 children with splenic primary solitary tumor conifrmed by surgery and pathology from January 2010 to August 2015 were retrospectively studied. The related literatur were reviewed. Results In 6 children, 2 children of cystic lesions, ultrasound showed anechoic mass, CT scan showed low density mass, without change after contrast, pathologically conifrmed as congenital cyst;2 children’s ultrasound showed solid echo, color Doppler ultrasound explored the blood lfow signals, contrast CT showed the lower strength around the splenic parenchyma, pathologically conifrmed as splenic lymphangioma;one child’s unltrasound showed echo mass with rich signals of blood lfow, MRI scans showed T1WI, T2WI and other signals of lumps, with little homogenity after contrast, pathologically conifrmed as splenic hamartoma;one child’s ultrasound cannot distinguish tumor boundaries, contrast CT scan showed concentric filling reinforcement, pathologically confirmed as hemangioma. Conclusion Splenic primary solitary tumor in children is rare. There are no speciifc clinical characteristics. The image ifndings can deifne the locations and help the differential diagnosis. The ifnal diagnosis depends on pathology.

Humanistic doctor-patient communication is an essential capability for medical workers and is as impor -tant as medical technology .Its education has been getting more and more attention in recent years .However , the training and evaluation of humanistic doctor-patient communication as a practical other than theoretical capability has been difficult .A new method , clinical scenery drama , based on psychodrama and role theory , is developed by Dept.of Psychological Medicine , Peking Union Medical College Hospital from recent 10 years of medical doctor and student training .In clinical scenery drama , medical students are thrown to different roles to empathize with their feelings and conflicts , try to resolve clinical dilemma with humanistic communication technique besides medi-cal technology .Then the sharing and comments from teachers and observers help students to understand the situa -tion from other perspectives and think about other possible solutions .
