Objective To investigate the effect of leflunomide on the superficial costimulatory molecules expression of T lymphocytes in patients with lupus nephritis ( LN ). Methods The peripheral blood mononuclear cells (PBMCs) of female active LN patients and healthy female were separated by density gradient centrifugation, and cultured by phytohemagglutinin (PHA) or leflunomide active metabolites(A771726).The CD28, CD40L, CTLA-4 and LFA-1a expressions on the peripheral blood T lymphocytes were detected by double-colored flow cytometry. The differences of the means were tested by analysis of variance( ANOVA ) and SNK q test. Results Comparing with healthy controls, there were significantly higher expressions of CD28,CD40L, LFA-1a and CTLA-4 on the peripheral blood T cells in active LN patients (CD28:33.4±6.5 vs14.4±3.2; CD40L: 13.2±3.2 vs 5.4±2.3; LFA-1a: 8.5±2.3 vs2.2±1.1; CTLA-4:4.6±1.5 all P<0.01) as well as CD28 and CD40L expression on the peripheral blood T cells from healthy controls induced by PHA (CD28:26.8±6.7 vs14.4±3.2; CD40L: 13.9±4.9 vs 5.4±2.3 all P<0.01 ), but not CTLA-4 and LFA-1a expression.However, CD28, CD40L, LFA-1a and CTLA-4 expressions on T cells stimulated by PHA increased in active LN patients(all P<0.05 ). A771726 could significantly inhibit over-expression of LFA-1a and CD40L on the T cells from active LN patients (CD40L:8.2±2.0 vs13.3±3.2;LFA-1a:5.1±1.3 vs8.5±2.3 all P<0.01 ), but not CD28 and CTLA-4 expression. A771726 did not inhibit CD28, CD40L, LFA-1a and CTLA-4 expression on the T cells in healthy controls. Furthermore, A771726 could markedly inhibit the over-expression of all of the above molecules induced by PHA on the T cells of active LN patients (all P<0.05). Conclusion One of the major mechanisms for LEF treatment of LN is that LEF can down-regulate CD40L and LFA-1a expression but not CD28 and CTLA-4 expression on the peripheral blood T cells in active LN patients.

OBJECTIVE: To study the effects of Cordyceps sinensis on dimethylnitrosamine-induced liver fibrosis in rats. METHODS: SD rats were divided into normal control group, untreated group and Cordyceps sinensis-treated group. The rats in each group were fed with corresponding drug for 4 weeks. The rat's liver collagen deposition was observed with collagen staining. Hydroxyproline (Hyp) contents in liver tissue of the rats in 3 groups were determined with HCl hydrolysis. The tissue inhibitor of metalloproteinase-2 (TIMP-2) and type IV collagen contents were observed by Envision, and matrix metalloproteinases-2 (MMP-2) activity was detected by the method of enzyme-picture. Type I collagen was detected by Western blotting. RESULTS: The contents of Hyp, TIMP-2, type IV collagen, and the expression of type I collagen in untreated group were significantly higher than those in the normal control group, while those in Cordyceps sinensis-treated group were significantly lower than those in the untreated group. The content of MMP-2 in untreated group was significantly lower than that in the normal control group, while that in Cordyceps sinensis-treated group was significantly higher than that in the untreated group. CONCLUSION: Cordyceps sinensis can considerably relieve the liver fibrosis, and the mechanism may be related to promoting the degradation of the collagens.

Objective To study the effect of mixed purified autogenic and allogeneic hematopoietic stem cell transplantation for the treatment of systemic lupus erythematosus. Methods Thirty-six MRL/lpr mice were randomly divided into the control group, the study group,the mixed group ( the ratio of autogenic to hematopoietic stem cells, mixed in different proportions were infused intravenously after 60Co irradiation. The study group were treated with daily intraperitoneal infusion of dexamethasone 1 mg·kg-1·d-1, while the control group were treated with intraperitoneal infusion of equivalent volume of saline daily. The changes of serum creatinine level, the urine protein excretion of the mice and blood WBC count were compared. Repeat measures ANOVA was used for data analysis. ELISA was used for anti-nuclear antibody detection Light microscopy, electronic micros-copy, immunofluorescence were applied to detect the pathological changes in renal tissue. Results Serum creatinine and urine protein excretion levels increased with time in the ontrol group, while those of the transplant group and the study group decreased. The reduction in mixed transplantation group and the study group was more evident compared with that of the allogeneic group. The difference was statistically significant (P<0.05), but there was no significant difference between the mixed transplantation groups and the study group (P>0.05). The histopathologic damage was most serious in the control group as pathological injury score of most mice were in grade 3 or 4. The majority of the histopathologic damage of the allogeneic group was in grade 2. Most f pathological damage of the study drug group and the mixed transplantation group were grade 1 or 2. Conclusion Mixed hematoopoietic stem cell transplantation for the treatment of murine systemic lupus erythematosus can effectively correct heavy proteinuria in murine systemic lupus erythematosus so improve the renal damage. It is a safe and effectively way to treat murine systemic lupus erythematosus.
