Spermatic venography with hot contrast material embolization was undertaken in 81 patients with varicoceles and infertility. Long-term follow-up information was available in 91% of the patients, and there was an overall conception rate of 40.5%. Embolization with hot contrast material was easily performed without special embolization devices and proved to be a safe and effective technique. 相似文献

To investigate the membrane abnormalities that may play a pathophysiologic role in several hemolytic anemias we determined the density distribution on sucrose density gradients of human red blood cell (RBC) membranes from patients with these disorders, from normal controls, and from incubated normal RBC. We analyzed the fractions for membrane-adsorbed hemoglobin (Hb), globin, and nonglobin cytoplasmic proteins. The relationship between the cytoplasmic proteins adsorbed on the membranes and the specific gravity (SG) of the membranes was linear. An increase in SG of the entire membrane population was seen in Hb C disease due to adsorbed Hb. Subpopulations of membranes with increased SG due to adsorption of nonglobin protein were evident in the membranes from two splenectomized patients with hemolytic glucose-6- phosphate dehydrogenase (G6PD) variants. Dense membrane subpopulations found in RBC membranes from three splenectomized patients with Hb Koln were associated with adsorbed globin, while similar subpopulations in RBC membranes from three splenectomized patients with hereditary spherocytosis demonstrated increased SG due to adsorbed Hb. Splenectomized normals had no such abnormality in membrane density. Sucrose density gradients demonstrate that membrane bound cytoplasmic protein is characteristic of the RBC membranes in several hemolytic disorders. Additionally, gradients are useful for the isolation and further analysis of those subpopulations of RBC membranes with abnormal SG and exaggerated membrane protein abnormalities. 相似文献

AIM:To analyze whether high-intensity focused ultrasound(HIFU) ablation is an effective bridging therapy for patients with hepatocellular carcinoma(HCC).METHODS:From January 2007 to December 2010,49 consecutive HCC patients were listed for liver transplantation(UCSF criteria).The median waiting time for transplantation was 9.5 mo.Twenty-nine patients received transarterial chemoembolization(TACE) as a bringing therapy and 16 patients received no treatment before transplantation.Five patients received HIFU ablation as a bridging therapy.Another five patients with the same tumor staging(within the UCSF criteria) who received HIFU ablation but not on the transplant list were included for comparison.Patients were comparable in terms of Child-Pugh and model for end-stage liver disease scores,tumor size and number,and cause of cirrhosis.RESULTS:The HIFU group and TACE group showed no difference in terms of tumor size and tumor number.One patient in the HIFU group and no patient in the TACE group had gross ascites.The median hospital stay was 1 d(range,1-21 d) in the TACE group and two days(range,1-9 d) in the HIFU group(P < 0.000).No HIFU-related complication occurred.In the HIFU group,nine patients(90%) had complete response and one patient(10%) had partial response to the treatment.In the TACE group,only one patient(3%) had response to the treatment while 14 patients(48%) had stable disease and 14 patients(48%) had progressive disease(P = 0.00).Seven patients in the TACE group and no patient in the HIFU group dropped out from the transplant waiting list(P = 0.559).CONCLUSION:HIFU ablation is safe and effective in the treatment of HCC for patients with advanced cirrhosis.It may reduce the drop-out rate of liver transplant candidate. 相似文献

Background
In developing countries, overweight prevalence is increasing while underweight prevalence is still high. This situation is known as the double nutrition burden. Both underweight and overweight are related to increased risk of chronic non-communicable diseases, reduced well-being and quality of life. This study aims to compare the prevalence of overweight and underweight among Vietnamese adults in 2000 and 2005. 相似文献90.
