Objective To study the therapeutic effect of temporary hepatic venous occlusion(TACE-THVO) in transplanted hepatoma rat model and to compare the effect between the adriamycin or the athanol iodized oil emulsion. Methods The seventy five SD rats with transplanted hepatoma were classified into five groups. In the control group, TACE-THVO was performed separately by injecting the adriamycin or the ethanol iodized oil emulsion. Within one week, ten rats in each group were all sacrificed. Then the results were analyzed by light microscopy and scanning electron microscopy.Results (1) Gross study results: within one week, the hepatoma volume in each group was reduced after therapy. The experimental groups showed a lower tumour growth rate than that in the control groups; (2) Light microscopy results: within one week, the area of the tumor necrosis and the capacity of the adriamycin or the ethanol iodized oil emulsion in the portal venous were increased in the experimental groups rather than that in the control groups. The area of the tumor necrosis with the adriamycin iodized oil emulsion was less than that of the ethsnol iodized oil emulsion; (3) Scanning electron microscopy results: within one week, the rough-surfaced reticulum showed a hydropic degeneration. There might be lipodol drop in the tumor nuceus, which appeared karyorrhesis. Conclusion The area of the tumor necrosis with the ethanol iodized oil emulsion is larger than that of the adriamycin iodized oil emulsion. TACE-THVO may be a effective therapy for the hepatoma.

Objective To investigate human plasma glycoproteomie changes related to human immunodeficiency virus (HIV) infection,and to identify glycoproteins with potential anti-HIV activity or anti-HIV drug targets. Methods Plasma proteins with lower abundance were enriched through affinity purification to remove albumin and IgG in clinical samples (HIV-positive patient, n= 10, and healthy controls, n= 20). Proteins were separated by two-dimensional electrophoresis (2-DE) and stained by Pro-Q emerald glycoprotein stain kits. The 2-DE image was analyzed by ImageMaster software to find differential glycoproteins. Furthermore, the depleted HIV-positive and healthy control plasma proteins were digested by PNGase F. Glycoproteins were deglycoliszed, separated by 2-DE and analyzed by ImageMaster software. Differential glycoproteins were identified by liquid chromatography combined with high capacity ion trap mass spectrometry (HCT). Results The pretreatment of HIV-positive plasma prior to 2-DE could efficiently remove the high aboundant albumin and IgG in plasma and improve the detection of proteins with low-abundance. High revolution 2-DE gel images of glycoproteins from HIV positive and healthy control plasma samples were obtained. Glycoproteins were successfully deglycolized through PNGase F treatment. Thirteen differential glycoproteins were identified by liquid chromatography combined with mass spectrometry. These proteins included alphalantitrypsin precursor and serine/threonine-protein kinase N1. Conclusions Potential HIV infection related proteins,such as alphal-antitrypsin precursor are successfully identified. Our study may offer some help to understand the molecular mechanism of HIV infection and select new drug targets for preventing HIV infection.

Objective To observe the surface structures of cardiovascular endothelial cells in situ with atomic force microscope (AFM). Methods Fresh aorta and aortic valve were dissected from 10 healthy male New Zealand white rabbits. Before fixed in 1% formaldehyde, the fresh tissues were washed in the buffer phosphate solution. Under general microscope, the fixed aorta or valve was spread on the double side stick tape which had already been stuck on the glass slide. The intima of aorta or the aorta side of valve was towards upside. Then the specimen was dried under 37 degrees centigrade in an attemperator and was washed with pure water. After dried again, the specimen was loaded on the platform ofNanoScope llla AFM and was scanned in tapping mode with the scanning speed of 0.5 HZ. Results The surface structures of endothelial cell on the fixed and dried tissue could be obsserved clearly in situ with AFM. Aortic endothclial cells were large, branched and arranged sparsely and parallel to the direction of blood flow, whereas endothelial cells on aorta valve surface were small, less branched and arranged intensively and vertical to the direction of blood flow. When the scanning range was dwindled, granular ultra-structures could be observed on the surface of endothelial cells, and, as the scanning range was dwindled further, fissure and convolution could be seen on the surface of granules from aortic endothelial cells. Centre cavity and surrounding swelling volcano-like structure could be seen on the surface of granules from endothelial cells of aortic valve. Conclusions It's feasible to observe the surface ultra-structures of cardiovascular endothelial cells in situ with AFM and morphological information provided by A FM might be of clinical value in future histopathological diagnosis.

Background The objective of this study was to assess the clinical safety and efficacy of vena cava filter (VCF) placement,with particular emphasis on the incidence and risk factors of inferior vena cava thrombosis (VCT) after VCF placement.Methods Clinical data of patients with venous thromboembolism (VTE),with or without placement of VCF,were analyzed in a retrospective single-center audit of medical records from January 2005 to June 2009.The collected data included demographics,procedural details,filter type,indications,and complications.Results A total of 168 cases of VTE (82 with VCF; 86 without VCF) were examined.Over a median follow-up of 24.2months,VCT occurred in 18 of 82 patients with VCFs (11 males,7 females,mean age 55.4 years).In 86 patients without VCFs,VCT occurred in only 6 individuals (4 males,2 females) during the study period.VCT was observed more frequently in patients fitted with VCFs than in those without VCFs (22% vs.7.0%).Conclusions The incidence of VCT in patients with VTE after VCF implantation was 22% approximately.Anticoagulation therapy should be continued for all patients with VCF placement,unless there is a specific contraindication.Almost all instances of VCT in patients with VCF implants in our study occurred after stopping anticoagulation treetment.The use of VCFs is increasing,and more trials are needed to confirm their benefit and accurately assess their safety.

PurposeTo explore the significance of dual energy CT in differential diagnosis of squamous cell carcinoma metastatic lymph nodes and lymph node tuberculosis in the neck.Material and Methods Twenty-five patients with a total of 62 cervical enlarged lymph nodes confirmed with squamous cell carcinoma metastasis or lymph node tuberculosis by pathology underwent dual energy enhanced CT scan. Iodine coverage value of two different kinds of pathological properties of lymph nodes was measured. The trend of the spectrum curve was observed and the energy spectrum curve slope of two kinds of lymph nodes were compared. The sensitivity, specificity and accuracy of energy spectrum curve slope in differential diagnosis were analyzed. Results Of all 62 lymph nodes, there were 32 squamous cell carcinoma metastatic lymph nodes and 30 lymph node tuberculosis. There were statistic significance in the iodine coverage between the squamous cell carcinoma metastatic lymph nodes and lymph node tuberculosis (t=3.806 and 3.698,P<0.05). In the range from 60 keV to 180 keV, CT value of the two kinds of lymph nodes decreased with increase of keV value. It showed the higher the keV value the less CT value decreased, with the energy spectrum curve of drop type. The area of the iodine coverage was 0.756 with the differential diagnostic sensitivity of 56% and the specificity of 80%. The area of energy spectrum curve slope was 0.898 with the differential diagnostic sensitivity of 76% and the specificity of 85%.Conclusion The iodine coverage value and the energy spectrum curve slope have significance in differential diagnosis of the cervical squamous cell carcinoma metastatic lymph nodes and lymph node tuberculosis. The energy spectrum curve slope is superior to the iodine coverage value in differential diagnosis.
