Objective To explore the findings and clinical value of bedside ultrasonography in superior vena cava(SVC) syndrome in children after cardiac operations for congenital heart disease. Methods Bedside ultrasonography was performed on 6 children suspected of SVC syndrome after 5-38 hours[(22?11) hours] postoperatively,to view the structure and blood flow of SVC and its main branches. All the patients were reoperated as soon as diagnosed. Results Five children got severe SVC obstruction, marked with stenosis, turbulent, continuous and high velocity in SVC. Color Doppler flow imaging presented almost absence of flow due to nearly complete occlusion of the innominate vein in 1 child. Ultrasonographic diagnosis was confirmed by the reoperative findings. All the patients were cured by reoperation and discharged with normal ultrasonographic results. Conclusions Bedside ultrasonography can provide early and accurate diagnosis in children with SVC syndrome after cardiac operation.

Objective: To investigate the alteration of bcl- 2 gene family in the rat brain and the molecular mechanism of neuronal apoptosis following traumatic brain injury. Methods: Male Sprague -Dawley rats were subjected to lateral fluid percussion brain injury(FPI) of mo derate severity. Bcl-2, Bcl-x and Bax protein expression was detected by immun ohistochemistry. Results: (1) The immunoreactivity of Bcl-2 and Bcl-x protein decreased in the hippocampus ipsilateral impact site as early as 6 h post-injury, and this was the main cause of down-regulation of the ratio of Bcl-2+Bcl-x to Bax. (2) During 1-3 d after injury, the Bax protein express i on increased significantly, while the Bcl-2 and Bcl-x protein expression decre ased relatively slow. The decreased ratio of Bcl-2+Bcl-x to Bax was mainly due to the Bax up-regulation. Conclusion: The bcl-2 gene family is involved in neuronal apoptosis after FBI, and the protein expression alteration of the family members leads the neuronal cell to apoptosis.

Objective To investigate the risk factors of early postoperative complications in patients undergoing pancreaticoduodenectomy. MethodsClinical data of 200 patients undergoing pancreaticoduodenectomy in our hospital from December 1999 to September 2002 were collected and analyzed retrospectively. Nine clinical factors were recruited for the study in relation to surgical complications. ResultsThe overall early postoperative complication rate was 21% (42/200). Logistic regression analysis revealed that no T tube drainage(OR=10.015), preoperative total serum bilirubin level over 171.1?mol/L(OR=7.756), preoperative diabetes (OR=4.086), end-to-end pancreaticojejunostomy (OR=2.616), intraoperative blood transfusion over 1000 ml (OR=2.410), over 65 years old (OR=2.162) were important factors for early complications. ConclusionsT tube drainage, end-to-side mucosa-to-mucosa pancreaticojejunostomy and good surgical expertise can decrease early morbidity rate.
