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.

BACKGROUND: Child neglect is one of the most important aspects of child abuse and has become a serious problem influencing children's development all over the world. Therefore, it is necessary to nderstand the current conditions and influential factors of child neglect and establish effective evaluation methods in China.OBJECTIVE: To investigate the current conditions and influential factors of urban child neglect in Suzhou city.DESIGN: A comparative analysis of sampling survey.SETTING: Department of Children's Health Care, Soochow University Affiliated Children's Hospital.PARTICIPANTS: This study was conducted in one public kindergarten and two private kindergartens of urban areas in Suzhou city between March and October 2003. Totally 370 children (196 boys and 174 girls) aged between 4 to 6 years old without obvious physical and mental diseases were voluntarily investigated, and they had been living with the person that answered the questionnaire regarding to child neglect in China in the recent 1 year. METHODS: Questionnaire regarding to child neglect in China was sent to each volunteer.he questionnaire evaluates the current conditions of child neglect by 20 items of 5 aspects including physical care (buy fruit for child, consider the nutritional need of child, care about the body height and body mass of child), emotional care (chat with child, play and tour with child, encourage child to do the things whatever they can, listen to what the child feels, introduce the child to the guests when they come to your home, let him or her stop immediately when child cries, care about the activities in kindergarten), education care (buy books for child, tell stories to child, recognize and correct the bad behavior of child, answer the questions asked by child seriously), safety care (protections against fire and electricity at home, warn child against matches, knives and other sharp things, teach child how to cross the road) and health care (prepare the common medicine for child at home, urge child to brush teeth, correct the bad posture). The volunteers were asked to answer each question objectively according to the conditions of child within the recent 1 year, and each question should be answered by selecting only one choice (never, occasionally, usually, always), and anyone should not be omitted. Meanwhile,the educational background and occupation of the parents were also investigated.MAIN OUTCOME MEASURES: The general status of child neglect and the effects of different family educational background and occupation of parents on child neglect were observed. RESULTS: Totally 370 questionnaires were sent out, and 370 qualified ones were recollected, the effective rate was 100%. ① In Suzhou city, the children were given better regards and good care in the aspects of education, medicine and safety, but neglects on children's physical and mental care still exists in a few families. ② Families of different educational background could think highly of the medical care, safety and psychical care of children, but neglects on education and emotional development more commonly existed in the families with the educational background under university. ③ All the families with different occupation could think highly of the medical care, safety and physical care of the children, but education and emotional development were better in the cadre families than in the ordinary families.CONCLUSION: In Suzhou city, the children are given better regards and good care in the aspects of education, medicine and safety, but some bad manifestations of child neglect exist in education and emotion, which are associated with the educational background and occupation of the parents.Further studies about the evaluation, prevention and intervention are needed for child neglect in China.

Objective To accurately understand multi-spot medical practice in China and evaluate its effect.Methods Operation data of 2008 and 2009 were gathered from all medical institutions in Kunming to analyze the effect of the practice trial using the fixed effect model.Results Under control of such factors as the scale and type of the hospitals,clinic visits of the second certified hospital benefited by the practice increased by 14％than before,whereas the medical revenue of the institution increased by 29％.The effect proves more significant in terms of total clinic visits and medical revenues at level-1 and level-2 medical institutions.Conclusion Multi-spot medical practice in Kunming proves successful as it increased medical service supply and medical revenue,especially for level-1 and level-2 medical institutions.This effect possibly results from releasing high-level physicians down to lower-level institutions,helping these institutions to attract patients.

The effects of betulinic acid (BA), a pentacyclic lupane-type triterpene, on the cell viability, cell cycle and apoptosis in human leukemia K562 cells were investigated. The effects of BA on the growth of K562 cells were studied by MTT assay. Apoptosis was assayed through Annexin V/propidium iodide (PI) double-labeled cytometry. The effects of BA on the cell cycle of K562 cells were studied by a PI method. The expression of Bax and capase-3 was detected by using Western blot. The results showed that BA was cytotoxic to K562 cells with an IC(50) of 21.26 mug/mL at 24 h. After treating K562 cells with 10 mug/mL BA for 72 h, the number of cells was reduced by 58%. BA induced apoptosis of K562 cells in a time- and dose-dependent manner. The proportion of cells in G(0)/G(1) and G(2)/M phases was decreased and that in S phase was increased after K562 cells were treated with BA for 24 h. BA treatment also increased the expression of the pro-apoptotic proteins Bax and caspase-3. It suggested that BA could inhibit the proliferation of K562 cells through the induction of cell cycle arrest and apoptosis. The antitumor effects of BA were related with up-regulation of the expression of Bax and caspase-3 proteins. BA may qualify for the development of new therapies for leukemia.
