Objective The decease of varicose vein and telangiectasis of lower extremity has always been difficult to treat.Regular treatments and medicines are invalid.This research aimed to study the effect of foam sclerotherapy and the long-pulsed 1064 nm Nd∶YAG laser in treatment of reticular veins and telangiectasis of lower extremity.Methods From January 2012 to June 2012,excluding deep and superficial veins valve insufficiency of the lower extremity through duplex uhrasonography,72 patients with simple reticular veins and telangiectasis of the lower extremity were treated with foam sclerosing agent injection combined with Nd∶YAG 1064 nm laser therapy.Results Of the 72 patients,cure was achieved in 38 cases,significantly effective in 32 cases,effective in 2 cases,and total effective rate was 100％.Follow-up showed that after 3 months 1 case was dissatisfied,3 cases were discontent,6 relatively satisfied,32 satisfied,and 30 very satisfied;after 12 months no cases were very dissatisfied,1 cases were discontent,9 relatively satisfied,28 satisfied,and 34 cases very satisfied.There were no severe complications in all cases.Conclusions Foam sclerotherapy and Nd:YAG 1064 nm laser can be used for different stages of the treatment process and different caliber of blood vessels.Treatment with foam sclerotherapy and Nd∶YAG 1064 nm laser for reticular veins and telangiectasia of lower extremity is a safe,simple and effective way.

ObjectiveTo investigate the expression of CXCR4 and CD133mRNA in primary lesion of primary gastric adenocarcinoma and the relation with clinicopathological features,and to explore the correlation of CXCR4 and CD133.MethodsThe primary lesion of primary gastric adenocarcinoma and normal tissues adjacent to gastric cancer were obtained from 50 patients.The diction of CXCR4 and CD133 protein expression was detected by the immunohistochemical staining,and the relative gray scale values of CXCR4 and CD133mRNA by semi-quantitative RT-PCR (Fisher' s exact probability method).Their relationship with clinicopathological features was also investigated ( Spearman relation analysis).ResultsThe positive rates of CXCR4 and CD133 protein in gastric cancers were 76.0％ and 66.0％ respectively,which were significantly higher than that in normal tissues adjacent to gastric cancer ( 16.0％ and 10％ ; P =0.000,P =0.000).The increment of relative gray scale values of CXCR4mRNA was associated with the larger tumor diameter,the later TNM stage and the occurrence of lymphatic metastasis( P ＜ 0.05 ).And the larger diameter of tumor,the later TNM stage were associated with the higher relative gray scale values of CD133mRNA (P ＜0.05).The levels of the relative gray scale values of CXCR4 mRNA and CD133mRNA were positively related(r =0.453,P ＜ 0.01 ).ConclusionsThe higher expression of CXCR4 and CD133mRNA correlateswith tumour diameter,TNM stage and lymphatic vessel invasion. The relative gray scale values of CD133mRNA increase with the increment of the relative gray scale values of CXCR4.

Objective To investigate the mechanism and cause of the inactivation of tumor suppressor gene RNF180 in prostate cancer cell line by observing the effect of 5-Aza-CdR on the RNF180 gene in prostate cancer cell line DU145. Methods MTT method was adopted to study the effect of 5-Aza-CdR(0,1,2,5,10,15 and 20μmoI/L)on the proliferation of prostate cancer cells. Western blotting,real-time PCR,and methyla-tion specific PCR(MSP)were separately used to detect the expression of RNF180 in prostate cancer cells before and after the treatment of the most suitable drug concentration(5μmoI/L). Results In a certain range,the effect of 5-Aza-CdR on the proliferation of prostate cancer cell line DU145 was increased with the increase of drug concentration and the time of drug treatment(P<0.05). After the treatment of the most suitable drug concentration,the protein and mRNA expression of RNF180 in prostate cancer cells was significantly increased(P<0.05),but the methyla-tion of the promoter region was obviously decreased. Conclusion 5-Aza-CdR can reverse the methylation status of RNF180 gene in DU145 pros-tate cancer cell line,and relieve the silencing status of RNF180gene expression.

Objective The purpose of this study was to assess the technical feasibility, safety and effectiveness of percutaneous transluminal angioplasty (PTA)for the treatment of severe limb ischemia caused by tibioperoneal arteries occlusion. Methods From June 2004 to May 2007,35 patients with critical limb ischemia (CLI)were treated on an intention-to-treat basis with tibioperoneal arterial PTA. Main outcome measures were technical success rate, primary patency rate, limb salvage rate and complications. Results The technical success rate of tibioperoneal arterial PTA Was 83%.Mean follow-up time was 11.5 months, primary patency rate and limb salvage rate were 57%and 82%,respectively.Mean length of tibioperoneal arterial PTA was 9.5 cm(4.5～14 cm),concurrent treatment of iliac artery or femoral-popliteal artery was carried out in 19 patients via either angioplasty or combined with stenting.There were three complications including arterial spasm and thrombosis in one, which Was relieved by thrombolysis and antispasmodics, and artery perforation in 2 cases, which was treated conservatively. Conclusion In tibioperoneal arterial occlusions in CLI patients, PTA is feasible with a high initial technical success rate and high limb salrage rate,tibioperoneal arterial PTA carries a lower morbidity and less severe complications. PTA is a safe, effective and good treatment alternative for CLI patients of tibioperoneal arterial occlusions.

Objective To clarify the significance of RNF180 expression in carcinogenesis and progression of prostate cancer by detection of RNF180 promoter methylation. Methods RNF180 expression was detected in human prostate cancer cell lines(PC3,LNCap,and DU145)and normal prostate cells(RWPE?1)via Western blotting,RT?PCR,methylation?specific PCR(MSP),bisulfite?sequeneing PCR(BSP),respectively, while RNF180 expression in human prostate cancer tissues and paired adjacent non?tumor tissue was detected via immunohistochemistry. Results The expressions of RNF180 mRNA and protein in prostate cancer cells were significantly lower than those in normal prostate cells(P<0.05),op?posite to what was observed for the methylation level of the RNF180 promoter. Additionally,the RNF180 expression in prostate cancer tissue was significantly lower than that in paired adjacent non?tumor tissue. Conclusion The RNF180 promoter is incompletely methylated in prostate can?cer cells,which may be a reason for the decline or silencing of RNF180 expression in cancer cells and tissues.

Objective An optimal radiation dose was made research on tumor cells to develop effective tumor fusion vaccines. Methods We used the RS 2000 biological X-ray radiation instrument to produce different dose of X-rays.Mouse liver cancer cells line,BNL 1ME a.7R.1(MEAR),was used for experiment.The RS 2000 biological X-ray radiation was applied to create different tumor cell clones,which could help us to study the rela-tionship between irradiation dose and tumor cells′proliferation activity.Furthermore,the fusion cells′anti-tumor ef-fect was examined by flow cytometry. Results High-dose radiation would induce the lower proliferation of cancer cells than low-dose irradiation do.Conclusions During the preparation of fusion vaccines,irradiation dose should be considered as a factor that would influence the tumor cells′ proliferation activity. When the dose of irradiation was appropriate,we could make safe and efficient integration cell vaccines.
