Objective To explore the clinical application of pereutaneous transluminal angioplasty(PTA) and endovascular bracket to treat lower extremity arteriosclorotic occlusion.Methods The clinical data of 36 patients(41 affected limbs)with lower extremity atherosclerotic occlusion who were treated with PTA and bracket implantation from Jan 2008 to Dee 2008 were summarized.Results The initial successful rate of PTA wag 95.1% (39/41).The clinical symptoms were considerably improved in 37 affected limbs,representing of pain disappearing,skin temperature increasing and the healing of refractory ulcer.The index of ankle to brachial significantly increased from 0.54±0.11 to 0.79±0.15(before v.s.after therapy).However,no improvement was observed in 3 affected limbs,and one affected limb Wag re-operated by the amputation.In the following 3 to 15 months.three superficial femorsI arteries were re-obstructed at the 5th,6th,12th month,respectively.One arteria tibialis pesterior was re-obstructed at the 8th month.The cumulative cure rate was 89.7%(35/39).Conclusions PTA is effective in treating atherosclerotic occlusive diseases.The endovascular bracket can increase the cumulative cure rate.PTA and endovascular bracket are safe and effective in treating lower extremity arteriosclerotie occlusion.

Background and purpose:The prognosis in patients with early breast cancer(EBC) was poorly defined by clinical and histopathological features.There were more than 200 genes that might be correlated with development,progression,recurrence and prognosis of breast cancer in the published literature.This study evaluated the prognosis of patients with EBC at molecule level according to the protein expressions of 16 selecting genes(HER2,ER,PR,BCL2,Ki-67,BMYB,Cyclin B1,STK15,MMP11,BAG1,NM23,PTEN,P53,P27,VEGF,PCN A).Methods:The immunohistochemical method was used to detect the protein expressions of these genes in 76 patients with EBC and the statistical analysis was performed by COX proportional hazards model.Results:COX proportional hazard model revealed that BCL2,VEGF and STK15 were independent prognostic factors for patients with EBC.A formula of PI was set up according the three genes.The predictive outcomes with PI were compared with the actual follow-up outcomes in 48 patients with EBC.As a result,the predictive accuracy of good and bad prognosis was 86.67% and 91.67%,respectively.Conclusion:A formula of PI derived from protein expressions of the 16 genes correlated with breast cancer was ultimately set up and might be used to predict the outcomes of the patients with EBC.

OBJECTIVE: To observe the effects of Qingdan Capsule (QDC) and Yanggan Lidan Granule (YGLDG), two kinds of compound traditional Chinese herbal medicines, on biochemical parameters in guinea-pigs with pigment gallstones. METHODS: An animal model of pigment gallstones was established in male guinea-pigs by hypodermic injection of lincomycin. The guinea-pigs were randomly divided into blank control group, untreated group, QDC group and YGLDG group. There were 8 guinea-pigs in each group. After ten-day treatment, animals were sacrificed and sampled to calculate the rate of stone formation, total bilirubin (TB), unconjugated bilirubin (UCB) and Ca2+ density in bile of the four groups. RESULTS: In comparison with the untreated group, the rates of stone formation in the QDC and YGLDG groups were significantly decreased (P<0.01). TBIL, UCB and Ca2+ content of bile in both QDC and YGLD groups was also significantly decreased (P<0.05, P<0.01). CONCLUSION: QDC and YGLD have good effects on biochemical changes of animal model of pigment gallstone in reversing the lithogenesity of bile by reducing the content of TB, UCB and Ca2+, hence resulting in clinical treatment and prevention of pigment gallstone disease.

BACKGROUND:Previous studies have reported that rapamycin can affect the proliferation, migration and adhesion abilities of endothelial progenitor cels, but there is no report on the effect of autophagy, as wel as the interaction between autophagy and apoptosis. OBJECTIVE: To observe the effect of rapamycin activated autophagy activation on the proliferation, apoptosis, and cycle of endothelial progenitor cels. METHODS:Density gradient centrifugation was used to obtain mononuclear cels from bone marrow, and the mononuclear cels were inoculated on human fibronectin-coated culture plate.Then after cultured for 7 days the adherent cels colected were the endothelial progenitor cels. Different concentrations of rapamycin (0.01, 0.1, 1 and 10 μg/L) were added and cultured for 24 hours. Western blot was used to detect the LC3-II protein expression and monitor the induction of autophagy, flow cytometry was used to observe the cel cycle progression and apoptosis changes, and methylthiazolyldiphenyl-tetrazolium bromide colorimetric assay was used to observe the proliferation ability. Meanwhile, the ultrastructural changes were observed under transmission electron microscope. RESULTS AND CONCLUSION:Compared with the control group, there was no significant increasing of LC3-II protein expression of endothelial progenitor cels in 0.01 μg/L rapamycin group, and the LC3-II protein expression was in the high level. The LC3-IIprotein expression in the 1 μg/L and 10 μg/L rapamycin groups was higher than that in the control group, but lower than that in the 0.01 μg/L rapamycin group, which indicated that autophagywas particularly active when the concentration of rapamycin was 0.01 μg/L. The apoptosis of endothelial progenitor cels was increased with the increasing of concentration of rapamycin, and the proliferation rate was decreased with the increasing of concentration of rapamycin. The results indicate that activation of autophagy by bapamycin can promote the cel apoptosis, change the cel cycle significantly, and can inhibit the proliferation of endothelial progenitor cels.

Objective To explore the effects of Dimethyloxalyl Glycine(DMOG)on isehemic acute renal failure(iARF)in mice and its relationship with activation of hypoxia inducible factor 1α(HIF-1α).Method Twenty five C57/BL male mice were divided into 5 groups randomly:control group,DMOG group,sham operation group,ischemia/reperfusion(I/R)group and DMOG pretreated group(DMOG+I/R).Ischemia/reperfusion injury was induced in mice by clamping both renal pedicles for 30 minutes.The expression of HIF-1α was determined by Western blot.Renal function was reflected by blood urea nitrogen(BUN)and serum creatinine(Scr).Morphologic changes were evaluated under light microscopy.Apoptosis in the kidney was detected by TUNEL staining.Expression of Vimentin,a marker of tubulointerstitial damage was detected by immunohistochemistry.Results The elvated levels of of BUN((65.8±2.6) vs (13.6±0.7),P＜0.01],and Scr[(229.5±11.2) vs (6.5±0.8),P＜0.01]andwere found morphological injury were induced by the ischemic insult in I/R group.Administration of DMOG dramatically improved renal function[BUN,(26.3±6.5)vs(65.8±2.6);Scr,(27.0±14.1)vs(229.5±11.2),P＜0.01]associated with amelioration of tubulointerstital damage.In the DMOG treated group,the protein level of HIF-1α in the kidney of mile was also up-regulated significantly.Conclusions The protection against iARF in mice by DMOG administration is mediated by activation of HIF-1α.

Objective To investigate the effect of proliferation,apoptosis and cell cycle of 3-MA on rat endothelial progenitor cells. Methods Bone marrow-derived mononuclear cells were isolated from rat bone marrow by ficoll. There were five groups. The control group and four 3-MA concentration groups: 1. 25 mmol/L,2. 5 mmol/L,5 mmol/L, 10 mmol/L. MTT was used to measure the proliferation of endothelial progenitor cells. Flow cytometry ( FCM) was used to detect cell apoptosis and cell cycle. Results (1)5 mmol/L 3-MA promotes proliferation of endothelial progenitor cells, while 10 mmol/L 3-MA inhibits the proliferation of endothelial progenitor cells (P ＜ 0. 05). (2) 10 mmol/L 3-MA promotes apoptosis of endothelial progenitor cells, compared with the control, the difference was significant ( P ＜ 0. 05 ). (3) 3-MA at the concentration of 5 mmol/L reduces cells at G0/G1 phase and increases S and G2/M phase cells; 10 mmol/L 3-MA induces endothelial progenitor cells blockade at S phase, G2/M phase cells decreased, compared with the control, the difference was significant (P ＜ 0. 05). Conclusions 5 mmol/L 3-MA promotes the proliferation of endothelial progenitor cells. 10 mmol/L 3-MA inhibits the proliferation and promotes apoptosis of endothelial progenitor cells.

Objective To evaluate balloon angioplasty and stenting of the hepatic veins for the treatment of Budd-Chiari syndrome with long segmental inferior vena cava (IVC).Methods The hepatic veins were evaluated by colour Doppler,CT or MR.Epidiaphragmatic inferior vena cavography was performed to locate the stenused opening of the hepatic veins,in case of membrane occlusion of the hepatic veins,a puncture was attempted with Rups100 needle and then balloon dilation of the hepatic veins and stents implantation was carried out.Results In 40 cases of long segmental inferior vena cava ( IVC ) occlusive Budd-Chiari syndrome,membranous obstruction of the hepatic veins was found in 5 cases and short-segmental occlusion in 24 cases.28 cases were successfully treated with balloon dilation and stents implantation,including percutaneous transluminal angioplasty(PTA) of hepatic vein in 5 cases,and stent implantation in 23 cases,puncture procedure was failed in 1 case.Postoperative follow-up was made in 26 cases from 6 to 62 months ( mean,24.0 ± 1.3 months ).Symptoms recurred in 6 cases.Hepatic vein restenosis or occlusion were observed using color Doppler ultrasound in 6 cases.Conclusions Most lesions in hepatic veins were membranous obstruction or short-segmental occlusion among patients with long-segmental occlusion of IVC.Balloon angioplasty and stenting of hepatic veins for long segmental IVC occlusive Budd-Chiari syndrome through jugular vein can relieve hepatic venous obstruction and relieve portal hypertension.

Objective To evaluate the methods and efficacy of interventional treatment for subclavian arterial stenosis or occlusion retrospectively. Methods From Oct 2003 to Sop 2009,25 patients with subclavian arterial lesions , including stenosis in 13 cases and occlusion in 12 cases, underwent interventional treatment. Four patients received percutaneous transluminal angioplasty (PTA) alone, and concurrent 22 stents placement were performed in 20 cases. Results The technical success rate in stenotic lesions was 100% and in occluded lesions was 91.6% with a interventional failure in 1 case.
