Objective To study the evaluation between the X-ray findings and ultrasound(US) manifestations of upper digestiveobstruction in infancy.Methods X-ray and US manifestations of 20 cases of infant with upper digestive obstruction proved by operationwere analysed respectively.Results In 20 cases,12 patients had pyloric stenosis,3 duodenal stresia,3 midgut malformation,2 hiatalhernia.Pyloric stenosis was diagnosed by X-ray in 11 cases,by US in 9,misdiagnosed by US in 1 case.Duodenal stresia was observed by X-ray and US in 2 cases separately,not observed by X-ray and US in 1 case separately.Midgut malformation was demonstrated by X-ray and US in 1 case separately,not demonstrated in 2 cases separately.Hiatal hernia was found by X-ray in 2 cases,misdiagnosed by US in 2 cases.Conclusion The two methods can't substitute with each other but complement.X-ray is better than US in the diagnosis of pyloric stenosis and hiatal hernia.US is better than X-ray in the diagnosis of midgut malformation.

Objective To study the diagnostic method with computed radiography for congenital dislocation of the hip(CDH) and developmental dysplasia of the hip(DDH) in early stage in newborn and infant.Methods Followed-up with computed radiography made a comparison between 47 abnormal hips (CDH and DDH ) in 26 infants ,and 60 normal hips in 30 infants.Results (1)The normal pattern of acetabulum in neonate and infant appeared as definite“—”,indefinite“—” was considered as abnormal,its sensitivity,specificity and accuracy was 100%,91.59 and 85% respectively,and statistical comparison P

In order to reduce the working intensity of medical staff in inspecting patients during traditional infusion, a remote monitoring system for intravenous infusion is designed for solving the problem of delay in handling treatment during infusion process and to reduce the incidence of medical accidents. The system uses Visual Basic.NET language to develop the upper computer platform for infusion monitoring. It uses the Arduino control board and infrared photoelectric sensor to form a monitoring device to detect relevant information. At the same time, it uses Zigbee wireless sensing technology to transmit data and upload it to the software platform. The results show that the system can receive data from multiple monitoring terminal devices in the upper computer platform application interface at the same time. It can display the data in the nurse station in a graphical way, and perform alarm warning and information storage during the infusion process. The infusion monitoring system can observe the monitoring situation in real time, reduce the workload of medical staff, and further improve the operating efficiency and safety of the hospital.

OBJECTIVETo investigate the clinical value of high-field-strength intraoperative magnetic resonance imaging (iMRI) combined with optic radiation neuro-navigation for the resection of temporal lobe low-grade gliomas.

METHODSFrom April 2009 to September 2013, 65 patients with temporal lobe low-grade gliomas (WHO grade II) involving optic radiation were operated with iMRI and functional neuro-navigation. Diffusion tensor imaging (DTI) based fiber tracking was used to delineate optic radiation. The reconstructed optic radiations were integrated into a navigation system, in order to achieve intraoperative microscopic-based functional neuro-navigation. iMRI was used to update the images for both optic radiations and residual tumors. Volumetric analyses were performed using 3D Slicer for pre- and intra-operative tumor volumes in all cases. All patients were evaluated for visual field deficits preoperatively and postoperatively. The Student t test was used to evaluate the average rate of extent of resection between groups. Spearman rank correlation analysis was used to assess correlations between predictors and epilepsy prognosis.

RESULTSPreoperative tumor volumes were (78±40) cm3. In 29 cases, iMRI scan detected residual tumor that could be further resected, and extent of resection were increased from 76.2% to 92.7% (t=7.314, P<0.01). In 19 cases (29.2%), gross total resection was accomplished, and iMRI contributed directly to 8 of these cases. Postsurgical follow-up period varied from 13 months to 59 months, mean (33±13) months. Tumor progression were observed in 3 patients, newly developed or deteriorated visual field defects occurred in 4 patients (6.2%). For patients with pre-operative seizures, Engel Class I were achieved for 89.7% of them. Spearman rank correlation analysis revealed that seizure outcome (Engel Class) was related to increased excision of ratio (r=-0.452, P=0.004, 95% CI: -0.636--0.261) and larger tumors (r=0.391, P=0.014, 95% CI: 0.178-0.484).

CONCLUSIONSWith iMRI and functional neuro-navigation, the optic radiation can be accurately located, while extent of resection can be evaluated intra-operatively. This technique is safe and helpful for preservation of visual field for the resection of temporal lobe low-grade gliomas involving optic radiation.
