In order to understand the effect of oxidant and antioxidant on proteinuriaformation of rats with passive Heymann nephritis (PHN), vitamin E (VitE), malondialde-hyde (MDA), xanthine oxidase (XOD) in serum and urine, and 24 hours protein excretionin urine were measured. The results showed that in both rats of heterologous phase (day7) and autologous phase (day 14), MDA in serum and urine, VitE and, 24 h pro-tein excretion in urine were all markedly increased, while VitE in serum was significantlydecreased, however the XOD level in serum and urine were not much altered. Correlationanalysis revealed that there were positive correlation between the amount of urinary pro-tein and that of MDA in serum and urine, and also between that of urinary protein andVitE in urine. A negative correlation existed between the amount of urinaryprotein andVitE level in serum. These results suggested that in rats with PHN there be an hyper-lipidperoxchtion with an pypo-anti-oxidation.

OBJECTIVE:To observe the short-term efficacy and toxicity reaction of 2 regimens of taxotere combined with epi-rubicin in the neoadjuvant chemotherapy of breast cancer. METHODS:78 patients with locally advanced breast cancer were random-ly divided into TEC group(45 cases)and TE group(33 cases). TEC group was treated with taxotere 75 mg/m2 by intravenous in-jection,d1+epirubicin 60 mg/m2 by intravenous injection,d1+cyclophosphamide 500 mg/m2 by intravenous injection d1. TE group was treated with taxotere 75 mg/m2 by intravenous injection,d1+epirubicin 60 mg/m2 by intravenous injection,d1. 21 days were a treatment course for 2 groups,and there were totally 4-6 courses. In the 2 groups,efficacy and toxicity reaction were evaluated af-ter 4 weeks at least,and survival rate of 6 months was followed-up. RESULTS:The differences were not statistically significant in the short-term efficacy and toxicity reaction and survival rate between 2 groups (P>0.05). CONCLUSIONS:TEC and TC have similar short-term efficacy and safety in the treatment of locally advanced breast cancer. Both of them can be used as adjuvant medi-cines for neoadjuvant chemotherapy.

Objective　To investigate the direct antitumor effect of several surface molecules of Bifidobacterium bifidum 1101 such as whole peptidoglycan (WPG), lipoteichoic acid (LTA), and polysaccharides (PS) on human colonic adenocarcinoma cell line LoVo. Methods　MTT assay and flow cytometry (FCM) were used to evaluate the effect of Bifidobacterial surface molecules on the growth of LoVo cells. Morphological study, fluorescent polarimetry and differentiation-specific enzyme analysis were used to determine whether LTA treatment could induce the differentiation of the cells. Results　LTA but not WPG or PS significantly inhibited the proliferation of LoVo cells in a dose and time dependent manner. Cell cycle analysis by FCM revealed that LTA induced changes in cycle distribution resulting in G0/G1 phase commitment. Morphological alterations observed by light and electron microscopy indicated maturity of cytoplasm and nucleus following treatment by 50μg/ml of LTA. Membrane fluidity was also altered, and intestinal alkaline phosphatase specific for the differentiation of LoVo cells roused dramatically during culture in LTA. It was further found that LTA elevated ［Ca2+］i which resulted from Ca2+ influx instead of the release of stored calcium. Conclusion　These observations indicated that LTA was able to inhibit the growth of LoVo cells and induce the differentiation of the cells. Calcium influx may play an important role in this process.

Background and purpose: Mouse osteosarcoma model was widely used in osteogenic malignant tumor research, and it was helpful for studying the invasion and metastasis of the tumor cells when it was well marked in vivo. The purpose of this study was to establish mouse sarcoma cell lines (S180) that were infected with enhanced green fluorescent protein(EGFP). Methods: EGFP-S180 expressing strong EGFP fluorescence was acquired by electroblot, and supplemented with G418 (800 mg/mL), c-Myc was detected by laser scanning confocal microscopy. Meanwhile, the cancer-bearing model was established subcutaneously within the abdominal cavity. Results: EGFP-S 180 cells were cloned. There was no significantly difference between c-Myc expressions in S180 cells and those in EGFP-S180 cells (P>0.05), and between the cancer-bearing time subcutaneously and the time within abdominal cavity (P>0.05). Conclusion: According to in vitro and in vivo assay, it showed that EGFP-expressing S180 cells could be used for studying further the tumor biological behavior with fluorescence technology.
