Objective To analyse 35 cases with failure and malfunction hemodialysis access managed by interventional radiology. Methods 35 cases with failure and malfunction hemodialysis access were examined by angiography and treated by interventional management subseqently. 26 cases of thrombosis occlusilon were treated with thrombolytic therapy and 15 cases of malfunctioning hemodialysis access were done with PTA. Results The initial angiogram showed 9 patients with simple stenosis while 26 patients with thrombosis occlusion, with concurrent stenosis in 13 patients. The rate of immediate recanalization of thrombolysis was 88.4% (23/26). The PTA was successful in 12 cases, 7 of the 13 cases concurrent with stenosis and 8 cases with simple stenosis while the other 3 cases of the 15 cases confronted failure. Follow up was made in 6 patients concurrent with stenosis without further management and 3 patients failure to conduct PTA after thrombolytic therapy. Recanalization occurred in 7 cases within 1 month and then did in all the cases in 3 month. Conclusions Angiography and subsequent interventional management play a critical role in the diagnosis and treatment of failure and malfunction hemodialysis access.

Objective To investigate the feasibility and value of combined administration of rapamycin and low dose of cyclosporin A in kidney transplantation recipients. Methods Twenty-five recipients who received their kidney transplantations for 2 months to 10 years were transferred to a new immunosuppression regimen of combined administration of rapamycin,low dose of cyclosporin A and prednisone. During the clinical observation,the average serum trough level of cyclosporin A was maintained between 0.042 and 0.083 μmol/L,and the average serum trough level of rapamycin was controled to 4～8 μg/L. Meanwhile, the dosage of immunosuppressive drugs was adjusted properly according to the white blood cells counting,liver function,blood lipid level and clinical settings.Twenty-five kidney transplant recipients with usual immunosuppression regimen of cyclosporin A in combination with MMF and prednisone served as controls. Results Druing a follow-up period of 2 to 8 months,no acute rejection events were found in this group. All the recipients survived well with functional renal grafts. Two patients in the experimental group quitted during the follow-up. One was incurred to serious pulmonary infection diagnosed as cytomegalovirus infection,and another was sufferred from persistent unknown fever. Other main adverse effects included leucopenia, hyperlipemia and dental ulcer,similarly as control group. No significant abnormal liver function event was found in this group. Conclusions This new immunosuppression regimen of combined administration of rapamycin,low dose cyclosporin A and prednisone in kidney transplantation recipients could avoid or diminish the adverse and toxic effects of calcineurin inhibitors,mainlain well-functional allografts and not increase the incidence of severe untoward reactions. Meanwhile,the costs for taking medicine were also significantly reduced with this regimen. Therefore,it would be an ideal and optimal immunosuppressive maintainence regimen.

More than 50％ microRNAs (miRNAs) are located in tumor-associated genome of amplification region or fragile site,which may also act as oncogenes or tumor suppressor gene (TSG).Recently,researches show that the expression of miR-449 is lower in human gastric,lung and ovarian cancer,and may act as TSG.The abnormal expression of miR-449 plays a pivotal role in carcinogenesis and progression,and elucidating its function and regulatory,mechanism can provide valuable diagnostic,prognostic biomarker for cancer management.

Chromosomally encoded toxin–antitoxin (TA) systems are thought to result in growth arrest and eventual cell death upon exposure to environmental stress in E. coli. In the chromosome of cyanobacteria Synechocystis sp. PCC6803, the genetic organization of a 360 bp open reading frame (ORF), slr0664, and another small ORF of 256 bp, ssr1114, is similar to that of TA system. The predicted protein encoded by slr0664 is homologous to RelE, but neither homologue of ssr1114 nor ssr1114-encoding protein was found in TA system. To see whether slr0664 encodes a toxin protein, ssr1114 encodes an antitoxin, an expressing plasmid containing promoter Plac and PBAD, was constructed. In this construct, Both slr0664 and ssr1114 were controlled by Plac and PBAD, respectively. Expression of slr0664 in Escherichia coli results in the inhi-bition of bacterial growth, the expression of ssr1114 neutralize the toxicity of slr0664 expression. These re-sults show that slr0664 is toxin gene and ssr1114 is antitoxin gene, both ssr1114 and slr0664 constitute achromosomal TA system in Synechocystis sp. PCC6803.

Objective To observe the changes of osteoblasts and vascularization during osteogenesis by tissue engineering technique under the electron microscope and study the feasibility of improving vascularization of the tissue engineering bone by using the small intestine submucosa(SIS) as the scaffold. Methods The bone mesenchymal stem cells(BMSCs) were isolated by using the gradient centrifuge method.BMSCs were seeded in the SIS.The scaffold-cell constructs were cultured in vitro for two weeks.There were no cells on the SIS as control.They were implanted subcutaneously in the dorsa of the athymic mice.The implants were harvested after(in vivo) incubation for 4,8 and 12 weeks.The changes of osteoblasts and vascularization were observed under the transmission electron microscope and the scanning electron microscope. Results The BMSCs grew quite well.BMSCs differentiated on the surface of the SIS and secreted a great deal of extracellular matrices.The scaffold-cell constructs formed a lot of bone and vessels in vivo.The scaffold degraded after 12 weeks.No osteoblasts but vascularization and fibroblasts were observed as control. Conclusion SIS can be used as the scaffold for constructing tissue engineering bone as it can improve the formation of bone and vessels in vivo.
