AIM: To investigate changes of tumor necrosis factor-α (TNFα) and TNFR-Ⅰ expression in vital organs and their significance in the pathogenesis of multiple organ damage associated with endogenous endotoxin following major ***: Wistar rats subjected to a 35 % full-thickness scald injury were sacrificed at 12 h, 24 h, 48 h, and 72 h postburn, respectively. Meanwhile, eight rats were taken as normal controls. Tissue samples from liver, spleen, kidney,lung and intestine were collected to assay tissue endotoxin levels and measure TNF-α and TNFR-Ⅰ expression, In addition, blood samples were obtained for the determination of organ function ***: Endotoxin levels in liver, spleen and lung increased markedly after thermal injury, with the highest level in liver. The gene expression of TNF-α in liver, lung and kidney was up-regulated after thermal injury, while the TNFR-Ⅰ mRNA expression in liver, lung, kidney and intestine was shown decreased throughout the observation period. Thus, the mRNA expression ratio of TNF-α to TNFRⅠ was significantly increased postburn, particularly in pulmonary tissue (67-fold). In addition, the significant correlations between the expression of TNFR-Ⅰ or the expression ratio of TNF-α/TNFR mRNA in liver tissue and serum aspartate aminotransferase levels were noted (P ＜0.05-0.01). Similar results were also obtained between pulmonary TNF-α mRNA expression and myeloperoxidase activities (P＜0.01), whereas there was a highly negative correlation between levels of renal TNFR-Ⅰ mRNA expression and serum ***: Burn injury could result in the translocation of gut-derived endotoxin that was mainly distributed in the liver, spleen and lung. The translocated endotoxin then made the expression of TNF-α and TNFR-Ⅰ mRNA up-regulated and down-regulated respectively in various organs, which might be involved in the pathogenesis of multiple organ damage following burns.

AIM: To investigate the regulatory effect of paclitaxel on proliferation and apoptosis in human acute leukemia HL- 60 cells. METHODS: HL-60 cell growth was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tertrazolium bromide (MTT) colorimetric assay. Cell cycle kinetics and apoptosis were analyzed by flow cytometry and micro- scopic examination. In addition, DNA microarrays containing 14400 EST elements were used to investigate the gene expression pattern of HL-60 cells exposed to paclitaxel 1 μmol/L. RESULTS: Paclitaxel inhibited HL-60 cell growth significantly in a dose-dependent and time-dependent manner (P<0.01). Marked cell accumulation in G2/M phase and multinucleated cells were also observed after treatment with paclitaxel 0.1 and 1 μmol/L. Among 14400 EST elements, 277 genes were found to be markedly up- or down-expressed in the HL-60 cells treated with paclitaxel 1 μmol/L for 0.5 h, comprising 210 known genes and 67 unknown genes. CONCLUSION: Paclitaxel suppresses the growth of HL-60 cells in vitro by causing cell-cycle arrest and apoptosis. The results of microarray suggest that paclitaxel initiates apoptosis through multiple mechanisms.

为验证激光诱导击穿光谱(LIBS)对江西省环鄱阳湖水田污染区稻谷中铬元素的分析可行性,本试验以在该区收集的稻壳、糙米和白米作为研究对象,分别对所有样品进行LIBS测试,并利用火焰原子吸收法(AAS)对铬元素进行真实浓度检测。LIBS图谱显示稻壳中明显地检测到了铬元素的特征谱线,而糙米和白米则检测不到。AAS结果显示稻壳中Cr浓度远高于糙米,而白米中Cr未超标,同时,稻壳与糙米Cr浓度比率具有一定的梯度关系。结果说明,Cr在稻壳中的富集量高于糙米和白米,利用LIBS技术对稻壳中Cr进行检测具有一定的可行性,最终有望实现通过采集稻壳LIBS光谱信号,预测出糙米中重金属元素的分布规律,进而采用类似的方法获取大米中重金属元素含量。
