Objective To study the value of the changes of signal intensity at the jugular bulb in diagnosing sigmoid sinus thrombosis.Methods MR imaging examinations were performed in 27 cases with cerebral venous sinus thrombosis(transverse and sigmoid sinuses).The signal intensity at the jugular bulb was evaluated in comparison with that in 20 healthy persons,and the results were dealed with Wilcoxon rank sum test statistically.Results In sigmoid sinus thrombosis,the signal intensity at ipsilateral jugular bulb was higher than that in healthy group(P

Objective To explore the clinical meanings of serum CA19-9 levd in hepatocirrhosis patients. Methods 61 hepatitis B and hepatocirrhosis patients were as treatment group, and 35 normal were as control group. The content of serum CA19-9 was measured by dectrochemistry lighting and the liver function was determined too. According to Child-Pugh liver function integral method,the treatment group was divided into 27 cases of A grade,20 cases of B grade and 14 cases of C grade. Results The serum CA19-9 level in hepatocirrhosis patients was higher than that of normal group significantly(P< 0. 005 ). The serum CA19-9 level decreaed obviously through the treat- ment,thereinto A and B grade fell evidendy in the Child-Pugh liver function integral method( P < 0. 005). C grade was not significantly different(P<0.05 ). The serum CA19-9 levd was positivdy associated with TBiL, ALT and AST of liver function integral method. Conclusion The serum CA19-9 levd of hepatocirrhosis patients is improved in different degrees. And it can be a prognostic target and used to estimate the degree of damage of liver function of hepatocirrhosis patients.

Objective To investigate the endovascular treatment of peripheral vascular anomaly in children and its efficacy.Methods Eighty-three children with peripheral vascular anomaly were treated via endovascular means. Before and during the endovascular operation,all the cases were diagnosed as follows: arteriovenous fistula in 23 cases, cirsoid angioma 32 and cavernous hemangioma 28. The endovascular approaches included:①transcatheter embolization using coils or gelfoam sponge;② transcatheter embolization combined with local cirrhosis agents treatment.Results Immediate angiography after embolization showed all the arteriovenous fistulas and hemangiomas were efficiently occluded and the clinical presentation and symptoms improved greatly. Follow-up one to three years after operation demonstrated 100% of efficacy and 68.7% curative rate with no complications. Conclusions Endovascular approach for peripheral vascular anomaly in children is a micro-invasive, safe and effective way.

Objective To analyze the relationship between the levels of plasma total homocysteine (Hcy) and umbilical arterial with color doppler ultrasound with the severity of preeclampsia(PE).Methods A total of 70 cases of the third trimester of normal pregnancy, 72 cases of mild PE, and 66 cases of severe PE were selected.Then plasma Hcy levels and umbilical arterial with color doppler ultrasound were detected.Results Hcy levels were statistically significant difference among the normal control group,mild PE group,and severe PE group((8.950±0.585), (11.116±0.615), (14.648±0.620) μmol/L,P＜0.05).Umbilical artery blood flow parameter S/D values in severe PE group was significantly higher in mild PE group and in contrg.1 group (3.43 ±0.72 vs.2.86 ± 0.82 vs 2.75 ± 0.56, P＜ 0.05), while the control group, mild PE group had no significant difference(P＞0.05).Resistance index(RI) ,Pulsatility index(PI) in mild PE group and severe PE group were significantly higher than control group(0.60±0.05,0.78±0.07 vs.0.57±0.06;1.24±0.21,1.47±0.64 vs.0.67±0.35), and the differences among three groups were significant(P＜0.05), while the mild PE, severe PE group had no significant difference(P＞0.05).Hcy of mild PE group was positively correlated with S/D, RI and PI(r=0.548,P=0.009;r=0.587,P=0.008;r=0.324,P=0.02).Hcy of severe PE group was positively correlated with S/D,RI and PI(r=0.752,P=0.001;r=0.627,P=0.003;r =0.438,P=0.024).Hcy and the severity of PE was positively correlated (r =0.450, P ＜ 0.05), S/D and the severity of PE was positively correlated(r=0.316, P =0.002).RI, PI and the severity of PE was no correlation (r =0.024, P =0.726;r =0.054,P =0.649).Conclusion The levels of Hcy and S/D were related to the severity of PE.To reduce Hcy,and monitor S/D were new ways for the diagnosis and treatment of pre-eclampsia.

Objective To explore risk factors,prevention and treatment of common complications of benign esophageal stenosis treated with the retrievable covered stents in children.Methods Fifteen cases,diagnosed as benign esophageal stenosis by barium esophagogram were treated with retrievable covered stents under fluoroscopy,Then the stents were removed after 2-3 weeks.The cases were followed-up and complications were observed.Results The stents were successful implanted in all cases.The diet was improved obviously after operation,and gradually transformed from liquid,semiliquid to normal feeding.At the same time,narrow section gradually expanded from 0.1-0.6 cm to 0.6-1.5 cm.Postoperative follow-up was in 1,2,3 weeks and 3 months.Main complications were stents shift in 5 cases,esophageal restenosis in 2 cases,esophageal-tracheal fistula in 1 case,postoperative dull pain behind sternum and foreign body sensation in 6 cases.Relevant preventions and treatments were performed based on different complications.Conclusion It should not be ignored that complications after covered stent placement are more in children than in adults,preventions and treatments should be taken positively.
