Objective To study the clinical application value of multi-slice spiral CT iliac venography.Methods The iliac venography with multi-slice spiral CT was performed in 50 cases.150 mgI/ml contrast medium at 2.5～3.0 ml/s was administered via the veins of dorsum of foot and the delayed time was 16～22 s,the images were reconstructed by several methods.The imaging quality and imaging characteristic of iliac vein disease were analyzed.Results Helical CT venography was performed successfully in all patients.Venography showed vein complete occlusion in 31 cases,vessel stenosis or filling defect in 9 cases,normally in 10 cases.The quality of images included:excellent 24%(12/50),good 60%(30/50),bad 16%(8/50),the collectivity was 84%(42/50).Conclusion The multi-slice spiral CT iliac venography is of certain clinical applied value.

Objective To explore the risk factors of children with cerebral palsy during pregnancy and neonatal period in Xinxiang area.Methods A retrospective analysis of the relevant research data of cerebral palsy children in Xinxiang area was performed.The research objects were children with cerebral palsy born from May 1,2005 to April 30,2010.At the same time,3 healthy children were selected as the control group to analyze the related risk factors causing cerebral palsy in children.Results The risk factors of children with cerebral palsy in Xinxiang city were as follows : maternal nutritional status, vaginal bleeding during pregnancy, pregnancy-induced hypertension syndrome, and abnormal production history were associated with cerebral palsy (x2 =2.313,13.296,5.034,7.434, all P ＜ 0.05)during the perinatal period;related factors during neonatal period were premature birth,severe asphyxia, severe jaundice, and intracranial infection(x2 =4.637,29.50,4.633,5.107, all P ＜ 0.05).Multivariate Logistic regression analysis showed the history of severe asphyxia (OR =2.340,95 ％ CI: 1.250-4.440), severe jaundice (OR =4.110, 95％ CI:2.430-6.740) ,premature birth(OR =2.570,95％ CI: 1.410-4.770) ,pregnancy-induced hypertension syndrome (OR =2.350,95 ％ CI:I.020-5.440), vaginal bleeding during pregnancy (OR =73.600,95 ％ C1:3.060-17.750) and abnormal production history(OR =5.710,95％ CI: 1.250-26.310) were independent risk factors causing children with cerebral palsy.Conclusions The history of severe asphyxia, severe jaundice, premature birth, pregnancy-induced hypertension syndrome, vaginal bleeding during pregnancy and congenital dysplasia are independent risk factors of children with cerebral palsy in Xinxiang area.It should be strengthened to screen and standardize the management of high-risk newborn infants with cerebral palsy, and do well management for perinatal high-risk pregnant women management.Early prevention can help to reduce the incidences of cerebral palsy in local area.

Objective To investigate the correlation between AS160 hyperphosphorylation and 18Ffluorodeoxyglucose (18F-FDG) uptaking in invasive breast cancer.Methods Thirty-nine primary breast caner patients received PET/CT scan before operation and their maximum standard uptake values (SUVmax) were recorded.The levels of p-AS160 (Thr642) were detected using immunohistochemical method in breast cancer tissues.The association between p-AS160 (Thr642) levels and SUVmax was assessed using the Spearman nonparametric test.Results The 18F-FDG uptake of tumors of the 39 patients with primary breast caner was 6.1 ± 2.7 (SUVmax).There was one false negative case in PET/CT scan imaging,compared with postoperative pathologic result.The positive rate of p-AS160 (Thr642) was 76.9％,and it was positively correlated with SUVmax (r =0.672,P ＜ 0.001).Conclusion AS160 plays a significant role in the glucose metablism of breast cancer tissues and its hyperphosphorylation may contribute to the increased uptaking of glucose in patients with breast cancer.
