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 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 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 explore the effects of a potential anti-oxidative plant,Erigeron multiradiatus(Asteraceae),plant materials from naturally distributed high-altitude populations at different stages of life cycle were collected.Methods Fifteen extracts obtained from the Ganzi region(Sichuan,China)were studied to assess their radical-scavenging ability on 1,1-diphenyl-2-picrylhydrazyl radicals and reducing power ability.Moreover,considering that anti-oxidants and free radical scavengers can also exert protective effect on endothelial cells from oxidative injury,these extracts were also evaluated for their anti-oxidative activity against cellular injury in the cultured human endothelial cell line(ECV304)induced by hydrogen peroxide(H<,2>O<,2>).Results All the extracts had radical-scavenging and/or reducing power ability,and the most active extract was found during flowering whereas the lowest appeared during vegetative growth period.The accumulation of anti-oxidative compounds was found to be affected by the altitude of growth environment.Total flavonoid content assay was also performed to support this outcome.Furthermore,these extracts also exhibited different effects on attenuating H<,2>O<,2>-induced cytotoxicity and inhibiting lipid peroxidation and LDH leakage from endothelial cells.Conclusion E.multiradiatus may be an important natural anti-oxidant and this property may contribute to verifying the utilization of this plant in Tibet folk medicine.

OBJECTIVE:To explore how to establish good procedure,system and mode of drug management,dispensing and application,in order to provide reference for risk management and rational use of rabies vaccine. METHODS:The use of rabies vaccine and storage temperature monitoring in our hospital during 2013-2014 were analyzed statistically,and risk management and use of rabies vaccine in our hospital were analyzed,and management measures and attentions were put forward. RESULTS:The amount of vaccinum rabiel (Vero cell) and human rabies immunoglobulin in our hospital were increased in 2014,compared to 2013. The position labeled with #1 in storehouse and that of labeled with #1 and #2 in dispensing store could meet the storage condi-tion of rabies vaccine. Risk management could be carried out in fields of drug requisition,cold chain management,drug manage-ment and drug dispensing. ADR should be paid attention. CONCLUSIONS:It is of significance to develop risk management and ra-tional medication guidance of rabies vaccine.
