Results:The cell proliferation rate , agarose clony-formation ability and spontaneous metastatic ability to lung of A1 and B1 were obviously h igher than that of A2 and B2 and the difference was statistically significant( P

Objective To investigate the clinical features of anuria caused by pediatric congenital bilateral ureteral stenotic obstruction,and to improve the diagnosis and treatment of the disease.Methods This series included 7 infants(2 males and 5 females;age range,35-57 d) with congenital bilateral ureteral stenotic obstruction.The clinical presentations were characterized by sudden anuria or oliguria.B-ultrasound,cystography and puncture pyelography were performed in all of them,and magnetic resonance urography(MRU) in 3.Based on the definite diagnosis,resection of stenotic segment of the ureter or ureteral implantation was performed on them.Results The diagnosis was confirmed by puncture pyelography in all of the 7 cases.Six cases underwent phase I surgery and recovered.No ureteral stenosis and cystoureteral reflux occurred during a follow-up of 2-4 years.The renal function was normalized in them.One case had stenosis recurrence due to scar formation,and was cured by the second operation.Conclusions Anuria caused by pediatric congenital bilateral ureteral stenosis should be diagnosed and treated as early as possible.Definite diagnosis can be established by puncture pyelography and MRU.Resection of the obstructive segment of the ureter,protection of renal function,and ureteral implantation are the main therapies.

Background and purpose:The screening of the genes being related closely with the mechanism of osteosarcoma metastasis was a difficult point in the realm of orthopaedics.We screened differential expression gene of human osteosarcoma MG-63 cell sublines with different metastatic capabilities with cDNA microarray,and studied the molecular mechanism of osteosarcoma metastasis.Methods:Total RNA of human osteosarcoma MG-63 cell sublines A1 and A2 was extracted,purified to mRNA and then reversely transcripted to cDNA probe respectively.The cDNA probe of A1 was labelled with Cy3 and the cDNA probe of A2 was labelled with Cy5.The two samples were hybridized with the cDNA microarray.The hybridization signals were scanned by Agilent Scanner and obtained data were analyzed using Ima Gene 3.0 software and Genespring software.Results:222 differential expression genes were found between cell sublines A1 and A2 by analyzing gene expression profile.There were 119 upregulated genes and 103 downregulated genes in cell sublines A1.All differential expression genes belonged to six main function groups and 49 genes of these had very obvious differentce in expression.Conclusions:There were many differently expressed genes between A1 and A2 cell sublines and only part of them were closely associated with mechanism of osteosarcoma metastasis.The technology of cDNA microarray could analyze effectively gene expression profile of human osteosarcoma MG-63 cell sublines, and supply a new approach to study the mechanism of osteosarcoma metastasis

Angiopoietin family is a recently discovered type of cellular factors that specifically bind to the TIE-2 receptors located exclusively in endothelial cell membrane. The protein structures of this family members are similar. They can be structurally divided into three domains: an N-terminal region lacking homology to any known structures, an alpha-helical rich coiled-coil segment, and a fibrinogen-like domain. The distribution and biological activity of these factors are different in organism. Angiopoietin-1 as a agonist, mostly locates in close proximity with vascular endothelial cells, keeps the stability of blood vessels, enhances the affinity of vascular endothelial cells with surrounding cells and matrix, decreases the leakage of vessel. Ang-2 is a naturally occurring antagonist of Ang-1, exists in the angiogenic remodeling region and is related to the decrement of the stability of vessel. Ang-3 is widely distributed in multiple mouse tissues, while Ang-4 is expressed only in lung. Although Ang-3 and Ang-4 are structurally diverged from each other, they appear to represent the mouse and human counterparts of the same gene locus. Biological functions of Ang-3 and Ang-4 have not been elucidated yet. Angiopoietin family has potentially clinical applications for incurring illnesses which lead to vessel wound and vascular abnormal development.
