Objective To study the application of native pelvis and ureter in kidney transplantation. Methods Between 1977 and 2001, 1 364 kidney transplantations were performed in our institution. 18 cases of ureteral complication after kidney transplantation were treated with native pelvis and ureter. The mean age of the patients was 42 years. In 10 patients with urine leakage, 3 cases underwent pyeloureterostomy using native ureter, 2 cases ureteroureterostomy using native ureter and 5 cases pyelopyelostomy using native pelvis. Five cases due to short ureter underwent ureteroureterostomy using native ureter. Three cases of ureteral stenosis were subjected to ureteroureterostomy using native ureter.Results Two grafts were rejected. Sixteen patients developed a normal function of kidney postoperatively (follow up: 3 months to 8 years). Conclusion Application of native pelvis and ureter might be a therapy of choice when secondary reconstruction by re-ureteroneocystostomy is not possible.

Congenital adrenal hyperplasia(CAH) results from an inherited defect in enzymatic steps required to synthesize cortisol from cholesterol. 21-hydroxylase deficiency accounts for 95% cases of CAH. We have analyzed CYP21 genes of CAH by PCR direct sequencing. Our results shows three cases of CAH owing to multiple mutations of CYP21 gene; first case, IVS2AS, A/G, -13, Ile172Asn; second case, IVS2AS, A/G, -13, Ile236Asn, Val237Glu, Met239Lys; third case, Ile172Asn, C to G at 1590nt, Val281Leu, Arg484Pro, G to A at 2697nt. Mutations such as Ile236Asn, Val237Glu, Met239Lys, and Arg484Pro are first noted in Korea.

STUDY DESIGN: Changes of morphology and phenotype of cultured cells in media added lactate were observed. OBJECTIVES: To evaluate the effect of lactate on morphology and phenotype of cultured intervertebral disc cell. SUMMARY OF LITERATURE REVIEW: It was reported that lactate and pH were important factor in the degeneration of intervertebral disc. However the effect of lactate on morphology and phenotype of cultured intervertebral disc cell have not been studied. MATERIALS AND METHODS: Cells were dissociated enzymatically from rabbit nucleus pulposus. After attaining monolayer growth, the cells were incubated in media added 2mM or 5mM lactate. Total cell counts and morphological changes of the cells were periodically observed. Changes in cell phenotype were investigated by use of anti-collagen antibody stain. RESULTS: The cell groups added no lactate and 2mM lactate showed no difference in cell counts, morphology and phenotype. The cell group added 5mM lactate showed a reduction in final cell Counts and highel'ratio of fibroblastic cell in total population. Anti-collagen I Ab stained the Intra-and extra-cellular area of fibroblastic cells and intracellular area of chondrocytic cells. CONCLUSIONS: The current study suggests that high concentration of lactate inhibit intervertebral disc cell proliferation and accelerate morphological and phenotypical change to fibroblastic cell.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immunosuppressive cells derived from bone marrow stem cells.MDSCs can not only strongly inhibit the anti-tumor immune reactions mediated by T cells,but also directly accelerate angiogenesis,tumor progression and metastasis.Nonresolving inflammation (NRI),a major driving factor in the occurrence and development of tumor,and MDSCs are present in tumor microenvironment and become hot topics in recent years.However,the relationships between MDSCs and NRI,especially in the relevant molecular regulatory networks,have not been fully elucidated.The relationships between MDSCs and NRI,the molecular regulatory networks,the key regulatory points and the strategies for targeted treatment are reviewed in this paper based on the current literatures and the work achieved by our research team.

0.05).However,the level of PRG-1 protein in cerebral cortex of experimental group was significantly higher than that of control group at 7 d(t=2.347,P=0.041).Conclusion The up-regulated expression of PRG-1 in cerebral cortex may be associated with the recurrent neonatal seizure-induced brain damage.

ObjectiveTo investigate the effect of Schwann cells (SCs) transplanted into cerebral hemorrhage area on never restore in rat.MethodsSCs were expended and labeled with 5'-Bromodexyuridine (BrdU) in vitro, then transplanted into cerebral hemorrhage area of model rat. Double immunohistochemistry staining was used to detect the expression of BrdU/myelin basic protein (MBP) and BrdU/growth associated protein-43 (GAP-43) respectively.ResultsBrdU/MBP positive cells could be seen one week after transplantation and up to 13 weeks. GAP-43 positive cells appeared in 12 weeks and 13 weeks, which was more in Hippocamp.ConclusionGrafted SCs can participate in remyelination and promoter nerve restore.
