[Objective]To investigate the metaphase result of extensive fusion in treatment of spondylolisthesis combined with intervertebral disc degeneration of adjacent joints.[Methods]Seventy-nine cases of lumbar spondylolisthesis combined with intervertebral disc degeneration of adjacent joints were treated with extensive fusion and internal fixation from September 2002 to September 2007.JOA and VAS scores were assessed and compared pre-and post-operatively.X-ray and CT were performed to observe the stabilization of fusion joints,and satisfaction rate from patients was investigated.[Results]All patients were followed up for 2 to 6.5 years(mean,4.6 years).Post-operative JOA scores increased(P

Induction of immune tolerance is characterized by high efficiency,low toxicity and economic advantages,and immune tolerance has very important significance in organ transplantation.In the establishment of immune tolerance,dendritic cells (DCs) play the key roles such as clonal deletion or clonal anerge,expressing t-cell inhibiting factors,activating helper T cells electively and inducing regulatory T cells,especially CD4 + CD25 + regulatory T cells,etc.Similarly,CD4 + CD25 + regulatory T cells whose primary target point is dendritic cell also have various functions such as affecting dendritic cells'maturing,restraining dendritic cells'antigen presentation to T cells,inhibiting the activation of T cells in non-specific ways and inducing immune tolerance.Current research shows,dendritic cells and CD4 + CD25 + regulatory T cells regard each other as target point and work synergetically.Here we mainly discuss the function and interaction of dendritic cells and CD4 + CD25 + regulatory T cells in the immune tolerance.

Objective To observe the reception of using pig bone marrow stromal cells (BMSCs) that were transfected with human tissue factor pathway inhibitor (TFPI) to resolve the dysregulation of coagulation after liver xenotransplantation.Methods Pig BMSCs were immortalized by transfection with lentivirus containing SV40T and then transfection with human TFPI.At last the cells were tested for their ability to inhibit clotting in a model by co-incubation of human plasma,human monocytes and pig aortic endothelial cells.Results After transfection with SV40T,pig BMSCs were immortalized and similar to primary cells.The immortalized pig BMSCs showed a stable TFPI expression after transfection with human TFPI by lentivirus.Moreover,they showed the potential of regulating coagulation dysregulation in vitro.Conclusion Pig BMSCs transfected with human TFPI could solve the regulation dysregulation caused by TF activation effectively,and have the potential of resolving coagulation dysregulation in liver xenotransplantation.

OBJECTIVETo study the optimum acupuncture treatment program and the mechanism for treatment of cerebral infarction.

METHODSSixty-three cases were randomly divided into 9 groups. The four factors, times of manipulation, the retaining time of the needle, acupuncture instrument and acupoints,and their corresponding three levels were adopted respectively in treatment of each group. Then nerve function defect score and insulin resistance were observed before and after treatment.

RESULTSThe acupoints, the times of manipulation and the retaining time of the needle have significant effects on nerve function defect and insulin resistance (P < 0.01 or P < 0.05), and the acupuncture instrument has a significant effect on insulin resistance (P < 0.01). The choice of acupoints was the most important factor for acupuncture treatment of cerebral infarction.

CONCLUSIONAcupuncture for regulating The Governor Vessel with twice manipulations and retaining the needle for 60 min is optimum treatment program for cerebral infarction. The good regulating effect of acupuncture on insulin resistance is one of the mechanisms of achieving the therapeutic results.
