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.

The human GM CSF cDNAandEGFP cDNA were linked together with IRES and then inserted into the expression vector pCI Egr 1, which was constructed by substituting CMV promoter in pCIneo with the Egr 1 promoter(Egr EG).The vector was transfered into human bone marrow stromal cell line HFCL by Lipofectin TM . The results indicated that the activity of EGFP in transfected cells increased at 18h after exposure to 2.5 Gy. The amounts of secreted GM CSF and CFU GM in serum free supernatants of Egr EG was significantly higher than the control group. EGFP and GM CSF cDNA were successfully integrated and expressed in the cells, which were confirmed by FACS and RT PCR analysis respectively. These in vitro data provide an experimental basis for the in vivo use of gene therapy of GM CSF gene regulated by Egr 1 promoter to protect hematopoiesis from total body irradiation.

Objective To explore the motion features of cervical spine based on continuous X-ray images.Methods The cervical spontaneous continuous multi-frame sagittal images from flexion to extention positions were selected from cervical spondylosis patients (patients group) and healthy adult (normal group).After preprocessing and registration,the trajectory of single vertebral body were recorded,and the feature points of each vertebral body were extracted.Meanwhile,the rel ative geometry parameters and movement rate were calculated.Results The motion trajectory of patients' cervical spine C4-6 were different from healthy people.The angles between the left edge curve of the vertebral body (C4 and C5 vertebra) and the baseline of patients group were smaller than those of normal group in flexion position (all P＜0.05).There were instability in the movement of C4 vertebral body in patient group,and the volatility of the angle change,the rate of change and the frequency were larger.The relative position change of the adjacent single vertebral body in the patient group are smaller.Conclusion Through the preprocessing,registration,parameter extraction and result analysis,the changes of functional features in cervical spondylosis patients are truly reflected.And it also provides a new idea for dynamic analysis of cervical vertebrae based on X-ray images.

Objective To examine outcomes of superficial vein stripping for vein varicosis caused by combination of superficial and deep venous reflux and the effect on deep vein reflux. Methods From January 2004 to December 2006, twenty patients (22 lower extremities) with combined superficial and deep venous reflux were enrolled for evaluation, patients with superficial venous reflux alone worked as controls.All patients underwent superficial vein stripping and followed up for 2 years. Venous clinic severity score (VCSS) and color duplex ultrasound test were used to evaluate the change of clinic symptoms and valve reflux of deep veins. Results Preoperative VCSS of superficial and deep vein reflux group and superficial vein reflux group was 7.1 ± 2. 9 and 6. 6 ± 2. 0 respectively (P = 0. 44). At two years after operation the VCSS was 2. 3 ± 1.2 and 1.8 ± 0. 8 respectively without significant statistic differences, whereas comparing postoperative VCSS with individual preoperative parameters there was a significant decrease (P <0. 01). In combined superficial and deep vein group, deep venous reflux reduced in 7 limbs, progressed in 4 limbs, no change in 12 limbs. While in superficial reflux alone group, deep venous reflux occurred in 4 limbs.Conclusions Superficial vein stripping effectively improves symptoms of great saphenous vein varicosis of lower extremity caused by combination of superficial and deep vein reflux without a significant effect on the stares of deep vein reflux.

Objective To investigate the influence of heme oxygenase-1 (HO-1) on rat renal tubular epithelial cell apoptosis induced by albumin and the possible mechanism. Methods The renal tubular epithelial cells (NRK-52E) were cultured in DMEM/F12 1:1 medium as normal control group; NRK-52E cells were cultured with 30 g/L fat-free bovine serum albumin (BSA) as the BSA control group; NRK-52E cells were cultured with CoPP (Cobalt pretoporphyrin Ⅸ) 5 μ mol/L for 24 hours as the treatment group. MTT assay was used to observe the effects of CoPP on growth inhibition induced by BSA in NRK-52E cells. The effect of CoPP was observed in BSAinduced apoptosis with the fluorescence microscope dyed by AnnexinV-FITC PI. The levels of HO-1, and expression of Bcl-2 and Bax mRNA were detected by reverse transcript polymerase chain reaction (RT-PCR). Results Compared with normal control group, BSA inhibited the growth of NRK-52E cells (P<0.05) and increased cell apoptosis rate (P<0.05). The CoPP pretreatment partially inhibited the BSA-induced apoptosis(P<0.05). Compared with normal control group, HO-1 mRNA expression increased (0.44±0.06 vs 0.39±0.05, P<0.05) in BSA control group. Compared with the BSA control group, the expression of HO-1 mRNA significantly increased after CoPP pretreatment(0.50±0.06 vs 0.44±0.06, P<0.05 ). Meanwhile, BSA increased the expression of Bax mRNA (0.87±0.04 vs 0.67±0.03, P<0.05)and reduced the expression of Bcl-2 mRNA (0.25± 0.04 vs 0.42±0.02, P<0.05 ). CoPP could inhibit the effect of BSA (Bax mRNA: 0.75±0.07, Bcl-2 mRNA: 0.36±0.03, P<0.05, respectively). Conclusions BSA can increase the apoptosis rate significantly and regulate the expression of apoptosis associated proteins in mRNA level directly. CoPP inhibits these changes, which provides evidence to support the essential role of HO-1 in cytoprotective function .

OBJECTIVE:To optimize the extraction technology of polysaccharides from antlion and explore its effect on im-mune functions of mice. METHODS:Using content of polysaccharides as investigation index,the effects of extracting polysaccha-rides from antlion by water extraction method protease hydrolysis extraction(optimized by orthogonal test using extraction tempera-ture,enzyme dosage,extraction time as indexes),and diluted alkali extraction(optimized by orthogonal test using alkali concentra-tion,extraction temperature,extraction time as indexes)were compared. 128 KM mice were randomly divided into 4 groups,then randomly divided into control group(normal saline),polysaccharides low-dose,medium-dose,high-dose groups(20,40,80 mg/kg),8 in each group,iv in tail vein,0.2 mL/10 g,once a day,for 1 week,which were respectively used to determine the phago-cytosis percentage and phagocytic index of peritoneal macrophages,spleen and thymus index,lymphocyte transformation rate and serum hemolysin levels. RESULTS:The contents of polysaccharides by 3 methods were 14.48%,38.66%,30.62%,respectively. The content of polysaccharides by protease hydrolysis extraction was the highest,the optimal extraction technology were as follows as using 100 μg/g papain extracting 3 h under 40 ℃. Compared with control group,phagocytosis percentage,phagocytic index, spleen index in polysaccharides low-dose,medium-dose,high-dose groups were significantly increased (P<0.05),thymus index was significantly decreased(P<0.05),while lymphocyte transformation rate had no significant changes(P>0.05);serum hemoly-sin in polysaccharides medium-dose group was significantly increased (P<0.05). CONCLUSIONS:Protease hydrolysis extraction is suitable for the extraction of polysaccharides from antlion,the optimal technology is reliable. Polysaccharides from antlion show activity in enhancing mice non-specific immunity and humoral immunity.
