The endoluminal stenting is popular for more than two decades,even in China,encouraging achievements also are getting around the recent dacade.Endoluminal stents are not only applicated for all kinds of vascular stenosis,and nonvascular stenosis such as biliary tract,esophagus,trachea etc,but also are utilized gradually in the interventional treatment of cerebral ischemia and hemorrage in the recent years,especially for aortic aneurysm.There would still have a long way to go in China for further development in basic research,standardized procedure,and normalized followed-up.The main target for all the interventional radiologists in the foreseen future is how to develop new stents with independent knowlege property right and to expand the stents usage reasonably.

Objective To establish a new model of orthotopic-transplatation tumor of human malignant choroidal melanoma. Methods pEGFP-N1, the eukaryotic expressive plasmid of green fluorescent protein (GFP), was transfered into human malignant choroidal melanoma cell line (OCM-1) by liposome lipofectanine, then the cell clones with stable GFP expression were screened out by means of neomycin, fluorescence microscope, and flow cytometer. Two ?l cell suspension of OCM-1 cells with GFP expression with the density of 4.5?107-5.5?107 cells/ml was injected into the subretinal space of right eyes of 40 nude mice (40 eyes) under binocular operating microscope with left eyes as the control ones. The growth of the transplanted malignant choroidal melanoma was observed in vivo using the fluorescence stereomicroscope. The mice were killed at different time after the operation to observe the metastasis of the tumor to optic nerve, brain and other organs including lung, liver, kidney and spleen. Moreover, pathological detection and immunohistochemical staining of GFP was carried out. Results At the postoperative 10 th-12 th days, the growths of the transplanted malignant choroidal melanoma with dilated and distorted blood vessels and neovascularization were observed; at the postoperative 20 th-22 nd days, the melanoma occupied the whole cavity of vitreous body; and at the postoperative 24 th-26 th days, the transplanted tumor grew out of the eye. Metastases of the carcinoma to olfactory bulb, kidney, lung and liver were seen at the failure phase soon after the extra-ocular phase. The histopathological characteristics of the transplanted tumor were similar to those of human, and the results of immunohistochemical staining showed positive expression of GFP in the tumor cells. Conclusion The orthotopic model of malignant choroidal melanoma set up via injection of human malignant choroidal melanoma cells labeled by GFP into the subretinal space of nude mice may provide a new approach to investigate the natural courses of growth and metastasis of malignant choroidal melanoma.

Rhetsinine has been isolated from the fruits of Evodia rutaecarpa ( Juss. ) Benth. ~1H NMR and ~(13)C NMR assignments reported previously for rhetsinine were revised on the basis of UV, IR, ESI-MS,~1H NMR, ~(13)C NMR and X-ray crystallographic analysis.

miRNAs (microRNAs) are small RNA which regulate gene expressions at the post-transcriptional level.Recently studies have suggested that miRNA is associated with the development of diabetes mellitus and its complications.This artcle reviews the regulation of miRNA in diabetes mellitus and its cardiovascular complications,and the biomarkers' value and application of miRNA in the treatment of diabetes mellitus,aiming to develop new insight for the diagnosis and treatment of diabetes mellitus.

Objective To explore the effect of externally-applied white plaster on cervical radiodermatitis.Methods Ninety patients with cervical radiodermatitis were equally divided into the observation group and control group according to their admission order.Patients in the control group were treated with furacilin through moist packing as well as routine nursing and the patients in the observation group were given white plaster for external application as well as nursing healthcare education.The two groups were compared in terms of clinical effect,average treatment during,and adverse reactions.Results The total effectiveness rate in the observation group was significantly higher than that of the control group and the average treatment duration was significantly shorter (P<0.05).There were no obvious adverse reactions in both groups.Conchusions The white plaster is clinically effective for the treatment of cervical radiodermatitis.It is advantageous due to shortened curative course and no adverse reactions.

[Objective]To investigate the effect of chondroitinase ABC(ChABC) after spinal cord injury(SCI) in adult rats,and to evaluate the significance of treatment. [Methods]Forty adult Wistar rats were divided into two groups: the control group(group A),the chondroitinase ABC group(group B).The thoracic T10 spinal cord injury model was made by impactor model II manual.After SCI,group B animals received ChABC treatment,while group A animals only received blank saline.The locomotor functions(BBB score) and the neuroelectrophysiological changes(SEP&MEP) of the rats were evaluated.Twelve weeks after SCI,biotinylated dextran amine(BDA) was injected into the cerebral cortex to trace the corticospinal tracts(CST).Then two weeks after the tracing,the animals were killed and the spinal cord frozen sections were made.The tissue sections were processed with Cy3 fluorescence stain,HE stain and anti NF-200 immuohistological stain.The section images were analyzed by Image Pro Plus image analyzing software.All the statistics were performed by SPSS 13.0 software.[Results]At 4 weeks after SCI,group B had obvious higher BBB scores than control group(P

Objective To study on the expressions of IL-8mRNA,MCP-1mRNA and MIP-1mRNA and the counts of TAM and MC and their correlation in ovarian adenocarcinoma tissues.Methods detecting the expressive levels of IL-8mRNA,MCP-1mRNA In situ hybridization were derected,and MIP-1?mRNA and Envision immunohistochemistry wes used for the counts of TAM and MC.Results The positive rates of IL-8mRNA,MCP-1mRNA and MIP-1?mRNA expressions and the counts of TAM and MC were significantly lower in the cases of histologic grade G1,clinical stage Ⅰ+Ⅱ,no-metastasis of regional lymph node,and no-infiltration of peritumoral tissues than those in the ones of histologic grade G3,clinical stage Ⅲ+Ⅳ,metastasis of regional lymph node,and infiltration peritumoral tissues(P
