Objective To compare of intervention embolization and operation in the treatment of brain aneurysms.Methods 60 cerebral aneurysm patients using random number table method were divided into two groups each 30 cases,group A given intervention embolization;group B given surgical operation treatment.They were followed for 3months,the bleed Glasgow results score,matrix metalloproteinases 2(MMP-2) level change and the length of time were recorded.Results After treatment,A group total effective rate was 73.4%,postoperative treatment to bleed again rate was 10.0% (3/30),B group was 76.7%,6.7% (2/30),two groups had no statistically significant differences (x2 =0.09,0.22,all P > 0.05 ) before treatment M MP-2 level between ;The two groups was statistically significant ( t =1.21,P > 0.05 ) ;Two groups after surgical treatment 3 d MMP-2 levels were ( 20.1 ± 8.7 ) μg/L,( 35.7 ±8.9 ) μg/L respectively,which was statistically significant ( t =3.33,P < 0.05 ).A group of hospitalization time (8.6 ±1.5 ) d,group B ( 13.2 ± 1.3 ) d,the difference between two groups was statistically significant ( t =3.18,P < 0.05 ).Conclusion For brain aneurysm patients,the intervention embolization had no obvious difference in curative effect with operation,but could reduce the time in hospital and significantly reduced MMP-2 level.

OBJECTIVE:
To construct the RNAi targeting tumor necrosis factor receptor associated factor (TRAF1) gene, and to explore the effect of interference targeting TRAF1 on the biological behavior of gastric cancer cells.
METHODS:
We detected the expression of TRAF1 in BGC823, SGC7901, and MGC803 gastric cancer cell lines through the real-time PCR and Western blot; then we constructed three pLVXshRNA- TRAF1-shRNAs expression vector targeting TRAF1. When TRAF1 was interfered successfully, we selected the strongest interference efficiency ShRNA by real-time PCR and Western blot. Based on interference targeting TRAF1 on gastric cancer, we tested the cell proliferation activity and apoptosis through MTT assay and flow cytometry, and the cell migration by transwell migration assay.
RESULTS:
The expression of TRAF1 was increased in BGC823, SGC7901, and MGC803 gastric cancer cell lines compared with gastric epithelial cells (P<0.05), and the highest expression was in BGC823 gastric cell line. In the three TRAF1 shRNAs, the strongest interference efficiency shRNA was pLVX-shRNA-TRAF1-shRNA2. When the gene TRAF1 of BGC823 was interfered, the cell growing power was weakened and the apoptosis rate increased, and the cell migration had no difference.
CONCLUSION
The expression of TRAF1 is up-regulated in gastric cancer cell lines BGC823, SGC7901, and MGC803, and the most obvious one is BGC823. The interference targeting TRAF1 can successfully inhibit the expression of TRAF1 in gastric cancer cell line BGC823. TRAF1 can inhibit the apoptosis of BGC823 cells.

Objective To explore the diagnostic value of helical CT,fluid attenuated inversion recovery(FLAIR),magnetic resonance angiography (MRA)and susceptibility weighted imaging (SWI)at 3.0T MR for acute ischemic stroke (AIS).Methods 48 cases of AIS(<72 h)underwent conventional CT,MRI,MRA and SWI.The correlations between hyperdense middle cerebral artery sign (HMCAS),proximal hyperintense vessel sign(HVS),magnetic sensitive spatially-integrated susceptibility vessel sign(SVS),vascular dot middle cerebral artery sign(DMCAS),distal HVS and collateral circulation of the blood vessels surrounding leptomeninges expansion degree were analyzed.Results In 48 AIS cases,HMCAS were showed in 18(37.5%),DMCAS 12(25.0%),proximal HVS 33(68.7%), distal HVS 40(83.3%),SVS 43(89.6%)and surrounding soft meningeal vascular 39(81.2%).The difference between spatially-integrated SVS and HVS was statistically significant (P<0.05);For HVS and HMCAS responsibility blood vessels at the bottom,the difference was statistically significant(P<0.01).For pia mater lesions around the blood vessel and distal HVS display degree,the responsibility of the blood vessels was high consistency(P=0.789).The difference between MCA distal HVS and DMCAS was statistically significant (P<0.01).Conclusion It has obvious consistency for SVS,proximal HVS and HMCAS of MCA on the responsibility of AIS.SWI is better than FLAIR and CT.It has obvious statistical sighificance between DMCAS,HVS and surrounding leptomenings vasodilatiov.
