Objective:To investigate the effect of ultrasound on the ultrastructure and expression of P-gp of Neuroblastoma cell in order to discuss the mechanisms of ultrasound affecting the chemotherapeutic sensitivity of SK-N-SH cell. Methods:The SK-N-SH cells were divided into the experimental group and the control group. In the experimental group,the cell suspensions were exposed to ultrasound irradiation. In the control group,the cell suspensions were exposed to sham irradiation . The changes of ultrastructure of tumor cells were observed by scanning electron microscope and the expression of P-gp in two groups were detected. Results:(1) In the pictures took by scanning electron microscope,we found that: the configuration of tumor cell changed and there were some holes of different diameters on the cell membrane and the numbers of microvillus reduced or disappeared after ultrasound irradiation.(2) The result of immunocytochemisty showed the expression rate of P-gp in SK-N-SH cells in the control group was 56.23%?9.86% vs 34.86%?6.19% in the experimental group (P
3.Diagnosis and treatment of spontaneous perforation of the bile duct in children
Journal of Chongqing Medical University 2007;0(12):-
Objective:To evaluate the etiology,elinic characteristics,diagnosis and treatments of spontaneous perforation of the bile duct in children. Methods:The clinical data of eight children with spontaneous perforation of the bile duct between 1998 -2006 were analyzed retrospectively. Results:5 of 8 cases were diagnosed bile duct perforativn before operation,all the patients recovered favorably after T-tube and pelvic drainage. 3 children complicated with choledochal cyst were cured afterⅡstage radical operation. Conclusions:the etiology of spontaneous perforation of the bile duct in children is unclear, panereaticobiliary confluence malfunction (PBCM) maybe the main reason. Peritoneocentesis is very important to the diagnosis, which is difficult in child preoperatively. The effective surgical treatments are T-tube and pelvic drainage. The children complicated with PBCM needⅡstage radical operation,and long term follow up are necessary for the children present with spontaneous perforation of the bile duct without PBCM.

Objective To summarize the perioperative nursing experience in nursing children with formaral angulation deformity treated with sreminobicular crib external fixator. Method The clinical data of 15 children with formaral angulation deformity treated with sreminobicular crib external fixator were reviewed. Results All 15 children got recovered, with the femora extended by 4~9 cm. After operation, all of them were affected by knee flexion dysfunction and foot drop to varied extents, which were improved satisfactorily after systematic training. Conclusions The systematic and progressive training can prevent knee flexion dysfunction and foot drop. Careful observation and effective nursing play an important role in the treatment of formaral angulation deformity.
6.Prenatal diagnosis and outcomes of fetuses with cutaneous hemangioma
Chinese Journal of Obstetrics and Gynecology 2000;0(09):-
Objective To study the ultrasonic characteristics of fetal cutaneous hemangioma and the association with perinatal outcomes.Methods Five fetuses with cutaneous hemangioma were detected by gray-scale and color Doppler ultrasound,compared with the result of pathology and hematology examinations after birth.Results Of the 5 cases diagnosed by ultrasound,3 had arteriovenous fistulas.In these 3 cases two fetuses developed high-output cardiac failure,and one developed cardiac insufficiency and thrombocytopenia.Finally one fetus was induced,one fetus died in the uterus and one neonate survived.The other two fetuses who had small tumors diagnosed by ultrasound did not develop any perinatal complications, and the neonates had favourable prognosis.Conclusions Massive hemangiomas are frequently associated with life-threatening complications such as high-output heart failure,thrombocytopenia and disseminated intravascular coagulopathy(Kasabach-Merritt syndrome).

Chinese Journal of Nervous and Mental Diseases 2016;42(11):658-663
Objective To compare and analyze differences in clinical characteristics, auxiliary examination and im?munotherapy between children with anti-N-methyl-D-aspartate(NMDA) receptor encephalitis and adults. Methods Clinical data was retrospectively collected from 34 cases anti-NMDA receptor encephalitis. All people were divided into the child group and the adult according to the age of onset and the inpatient department. Score of Modified Rankin Scale (mRS) before and after treatment and follow-up period (6 months~24 months) were compared to estimate the neurologi?cal outcomes. Results Data from 34 patients including 19 children and 15 adults was analyzed. Hypoventilation, epilep?sy and status epilepticus were more common in the adult group than in the child. The positive rate of EEG delta brush was higher in child group than in adult group. Two women were complicated by suspicious ovarian teratoma. Intravenous immune globulin was used commonly in the child group, while the plasma exchange or immunosuppressant used common?ly in the adult group. Time of onset to hospital admission and final diagnosis were shorter in the child group than in the adult. Patients requiring ICU were fewer in the child group than in the adult. The scores of mRS were significantly lower in the child group than in the adult at hospital discharge (P<0.05). Conclusion Clinical characteristics is more compli?cated in adults with anti-NMDA receptor encephalitis compared with children including a worse disease severity and a poorer short-term outcome.
