Objective To investigate the influence of CD4+CD25+ regulatory T cells (Tregs) on the disease progression in MRL/lps mice. Methods Tregs were separated by using magnetic beads from splenic cells of MRL/lps mice and BALB/c mice, and concentrated. Twenty-four MRLAps mice were equally divided into 3 groups, test group 1 injected with Tregs from MRL/lps mice, test group 2 injected with Tregs from BALB/c mice, and control group injected with physiological sodium chloride solution. Three weeks later, the levels of urine protein as well as serum anti-dsDNA antibody were determined; subsequently, the mice were sacrificed followed by histopathological and immunopathological examination of renal tissue. Results A significant decline was observed in the test group 1 compared with the test group 2 and control group in the urine protein score (10.63 ± 4.17 vs. 20.00 ± 5.35 and 18.75 ± 8.34, both P < 0.05), serum anti-dsDNA antibody level (5.36 ± 2.40 pg/ml vs. 9.57 ± 1.97 pg/ml and 10.75 ± 3.98 pg/ml, both P < 0.05), glomerular sclerosis index [(32.00 ± 12.09)% vs. (45.50 ± 13.68)% and (47.50 ± 10.78)%, both P< 0.05], and immunofluorescence intensity of IgG immune complex in renal tissue (1.88 ± 0.99 vs. 2.88 ± 0.64 and 2.75 ± 0.71, both P< 0.05). No significant difference was noted in renal tubule interstitial impairment index between the 3 groups (4.63 ± 1.92, 6.00 ± 1.07 and 5.75 ± 1.28, all P> 0.05). There was no statistical difference between the test group 2 and control group in terms of any of the above parameters (all P > 0.05). Conclusions Injection of Tregs from homologous mice could significantly down-regulate proteinuria degree, serum anti-dsDNA antibody level, glomerular sclerosis index and IgG immune complex level in renal tissue, and thereby decelerate the progression of renal impairment in MRL/lps mice.

Objective To explore the features of transsphenoidal microsurgical treatment of male pro- lactinoma and to evaluate the sexual function before and after transsphenoidal microsurgery.Methods A se- ries of 23 cases male prolactinoma were analysed combined with retrospective and prospective study.9 casese with sexual disfunction had finished the International Index of Erectile Function with 15-item questionnnaire (ⅡEF-15) before and after the surgery.Results 8/10 cases treated with dopaminergic agonist combined with surgery achieved complete remission,while only 4/13 cases achieved complete remission with surgery on- ly(x~2=5.490,P=0.036).Aecoding toⅡEF-15,sexual function improved after surgery in 9 cases(paired- sample) t test,P＜0.05).Conclusion Transsphenoidal microsurgical treatment of prolactinoma may im- prove the male sexual functions.Dopaminergic agonist combined transsphenoidal microsurgery may achieve a better outcome.

BACKGROUND:Currently, human umbilical cord derived-mesenchymal stem cel s are mainly for local transplantation, which has some shortcomings, such as large trauma, bleeding, complications, that limit its widespread application in clinical practice. OBJECTIVE:To investigate the feasibility of intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s for repair of spinal cord injury. METHODS:Eighty Wistar rats with spinal cord hitting were divided into five groups:blank control group with no transplantation (n=10), DMEM local transplantation group (n=15), DMEM intravenous transplantation group (n=15), cel local transplantation group (n=20), cel intravenous transplantation group (n=20). The functional recovery of spinal cord injury was observed with Basso, Beattie and Bresnahan scores at regular time as wel as hematoxylin-eosin staining and immunohistochemistry staining. RESULTS AND CONCLUSION:During 1 day to 2 weeks after transplantation, there was no significant difference in the Basso, Beattie and Bresnahan scores between the five groups;within 4-12 weeks after transplantation, the Basso, Beattie and Bresnahan scores were significantly higher in the two cel transplantation groups than the other three groups, but there was no difference between these two cel transplantation groups (P>0.05). Histological observation showed that the number of voids and glial scars was less in the cel local transplantation group and cel intravenous transplantation group compared with the other three groups, and there was also no difference between the two cel transplantation groups. These results indicate that the intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s is similar to the local transplantation in the repair of acute spinal cord injury, which is simple and avoids secondary injuries and various complications. It is recommended that this method provide a new approach for cel transplantation.

The fibrosis can occur in many kinds of organs,and its sustained progress may lead to organ structural damage and functional decline,and even the organ failure,which threatens the human health and the life seriously.Adenosine is an endogenous purine nucleoside that can be generated in various tissues of the body and regulate a multitude of body functions via the combina-tion with four different kinds of G protein-coupled receptors.Re-cent studies have found that adenosine receptors play an impor-tant role in regeneration tissue and fibrosis process.To under-stand the processes may be helpful to the treatment of fibrosis diseases.This review makes a summary on latest research pro-gress of adenosine receptors in fibrosis diseases.

Objective To induce mice bone marrow(BM) mono-nuclear cells into dendritic cells(DC) in vitro,and then produce function vaccine of anti-myeloma by bone marrow derived dendritic cells(BM-DC).Methods Mono-nuclear cells separated from mice bone marrow were cultured in tissue culture plastics which supplemented granulocyte-macrophage clonystimulating factor(GM-CSF),IL-4.During the 8 days,there were numerous of mature DCs outgrown,and then fused with SP 2/0 myeloma cells in logarithmic growth phase cultured with 8-azaguaine by polyethylene(PEG).The resulting purified DC/myeloma hybrids were generated by selecting with hypoxanthine-aminopterin-thymidine(HAT).The specific anti-tumor activity was examined in vitro.Results Mono-nuclear cells derived from BM cultured by supplement propriate cytokines milieu in tissue culture plastics,and then exposed to lipopolysaccharide(LPS).There were plenty of mature DCs appear as early as day 8,and exhibit dramatic veils of cytoplasm and extensive dendrites in their surfaces,high express CD11c(83.19%),major histocompatibility complex(MHC)-Ⅱ(95.25%),CD86(89.24%),their capacity to stimulate primary T cell responses in mixed leukocyte reaction(MLR) would be shown strongly.Hybrids could grow well through PEG fusion and HAT selection.These hybrids could stimulate naive T cells into cytotoxic T-lymphocyte(CTLs) directed against SP 2/0 myeloma,and exhibit strong specific killed ability.Conclusions BM-DCs is fused with tumor cells ensure the tumor associated antigens could be processed and presented effectively,and stimulate specific anti-tumor immunity so that prevent or cure this kind of tumor.So it's feasible in practice to produce anti-tumor vaccine by BM-DCs.
