Objective To evaluate the efficacy and adverse reactions of Navelbine(NVB)in the treatment of recurrent and metastatic breast cancer.Methods 34 patients with recurrent and metastatic breast cancer were treated with Navelbine in this clinical study,and 16 patients were treated by the NP(DDP+NVB)regimen,12 patients by the NA(ADM+NVB)regimen,6 patient by single-agent NVB.34 patients received above regimens for two cycles(3～4 week a cycle).Result The overall response rate(CR+PR)was 35.3%,clinical benefit rate(CR+PR+SD≥6 months)44.1%,disease contrrol rate(CP+PR+SD)58.8%,the median time to failure 3.4 months(range:0.7～11 months),the median time to progression(TTP)3 months(range:0.8～11 months),and the median duration of response(CP+PR)5 months(range:2～11 months).The main side effect of the therapies is bone marrow depression,and the grade Ⅲ～Ⅳ leucopenia is 35.3%.Conclusion Single Navelbine and Navelbine plus DDP(or ADM)are effective and well tolerated treatments in patients with recurrent and metastatic breast cancer.

Diabetic cataract is an metabolic-type cataract. Its pathogenesis mechanism is not completely clear. Researches demonstrated that glycosylation plays an increasingly important role in the formation of diabetic cataract,and increased blood glucose level promote the pathogenesis and progression of diabetic disease by accelerate the glycosylation response. Therefore, more researches on advanced glycation end products(AGEs) and its inhibitors is being concerned. The advance in the study of AGEs concept, its effect on diabetic cataract formation, the influence of AGEs inhibitor on diabetic cataract are summarized in this article.

Objective To investigate the effect of high mobility group box-1 protein (HMGB1) on inter-leukin-2 (1L-2) and interleukin-2 receptor α (IL-2α) expressions in human T lymphocytes and its potential regulat-ing mechanism in vitro. Method Human T lymphocytes were isolated and suspended, the cells were cultured with 20 μg/mL phytohemagglutinin (PHA) in 5% CO_2 at 37 ℃, recombinant human HMGB1 (rhHMGB1, 0, 10, 100, 1000 ng/mL) was added with the PHA and cultures were centrifuged at 12 and 48 hours for cell collect-ing. Reverse transcription polymerase chain reaction (RT-PCR) amplification was perfomed to determine gene ex-pressions of IL-2, IL-2Rα. IL-2, sIL-2R protein levels in cell culture supematants were measured by ELIZA. Re-sults After coincubated with rhHMGB1 (10, 100, and 1000 ng/mL) for 12 hours, IL-2 levels in cell culture su-pernatants respectively were 0 . 064 ± 0. 017 μg/L, 0.076±0.033 μg/L, and 0.061 ±0.02 μg/L, which were significantly higher compared with the untreated cells (0.045±0.011 μg/L, P < 0.05 or P < 0.01). Mean-while, IL-2 mRNA expression was markedly up-regulated following rhHMGB1 stimulation in various doses (F = 4.6872, P < 0.01). At 48 bourn, however, both IL-2 mRNA expression and protein production tended to de-crease along with an increased dose of dd-IMGB1 stimulationn. IL-2/sIL-2R ratio in 1000 ng/mL rhHMGB1 was markedly lower than that in 10 ng/ml rhHMGB1 (0.036±0.015 vs.0.055±0.017, P <0.05), together with down-regulation of IL-2Rα mRNA expression(P <0.01). Conclusions These data indieated that HMGBI could marked influence the IL-2/IL-2R expression in human T lymphocytes. With the increase in stimulating doses and prolongation of time, HMGBI might down-regulate T cell-mediated immune response of human lymphocytes.

BACKGROUND:More and more evidence have shown that autoimmune-induced inflammatory demyelinating mostly leads to optic neuritis that is quite an early manifestation of multiple sclerosis, but whether the pathogenesis of optic neuritis in experimental autoimmune encephalomyelitis (EAE) mice is correlated with helper T cellsubsets has rarely been reported.
OBJECTIVE:To analyze the correlation between pathogenesis of optic neuritis of mouse EAE model with helper T cellsubsets.
METHODS:The mice were injected intraperitoneal y Bordetel a pertussis to establish EAE models. Then, the animal models were subjected to immunization for 11, 15, 19 days, respectively. Mice undergoing intraperitoneal injection of normal saline served as controls (adjuvant group).
RESULTS AND CONCLUSION:Compared with the adjuvant group, the protein expression of interleukin 4 in the optic nerve decreased in the 19-day immunization group (P<0.05);the protein expression of interleukin 17 in the optic nerve increased in the 11-and 15-day immunization groups (P<0.05);the protein expression of interferonγin the optic nerve increased in the 15-and 19-day immunization groups (P<0.05);the protein expression of Foxp3 in the optic nerve decreased in the 11-, 15-and 19-day immunization groups (P<0.05). Real-time PCR results showed that compared with the adjuvant group, the mRNA expression of interferonγand Foxp3 in the optic nerve decreased (P<0.05), while mRNA expression of RORt increased in the 11-, 15-and 19-day immunization groups;the mRNA expression of interleukin 4, interleukin 17, T-beat increased in the 15-and 19-day immunization groups (P<0.05);the mRNA expression of GATA3 reduced in the 19-day immunization group (P<0.05). These results reveal that Foxp3 expression and helper T cellreduction have important influences on the development of optic neuritis in EAE mouse models, interleukin 17 may mediates inflammatory injury in the early stage, while interferon-γmakes inflammatory injury worse in the peak incidence of the disease.
