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.

Objective To explore the expression and activation of nuclear transcription factor ?B(NF ?B) in human breast cancer (BC), and the relationship between the activity of NF ?B and malignant potential of BC. Methods The protein expression of NF ?B p65 in BC tissue and paratumor tissue were measured by Western blot; NF ?B DNA binding activity was examined by electrophoretic motility shift assay(EMSA)in 26 BC tissues and 12 paratumor tissues of BC.Results The levels of NF ?B p65 protein and NF ?B DNA binding activity in the tumor tissue were higher than those in the paratumor tissues(P
