Based on the Stokes wave theory, the capillary-gravity wave and the interfacial internal wave in two-layer constant depth＇s fluid system are investigated. The fluids are assumed to be incompressible, inviscid and irrotational. The third-order Stokes wave solutions are given by using a perturbation method. The results indicate that the third-order solutions depend on the surface tension, the density and the depth of each layer. As expected, the first-order solutions are the linear theoretical results （the small amplitude wave theoretical results）. The second-order and the third-order solutions describe the nonlinear modification and the nonlinear interactions. The nonlinear impact appears not only in the n （n〉~2） times＇ high frequency components, but also in the low frequency components. It is also noted that the wave velocity depends on the wave number, depth, wave amplitude and surface tension.

Objective To evaluate the possible association between radon exposure and kidney cancer. Methods We performed a systematic review and a meta-analysis based on random effect models to provide a pooled association measure. Results We subjected 8 studies(overall relative risks and 95% confidence intervals: 1.01, 0.72 to 1.43, I2= 64.4%) to meta-analysis. Subgroup analysis revealed a marginally significant association between radon exposure and kidney cancer in studies conducted in Europe. Two population-based studies provided no evidence for the increased risk of kidney cancer in the general population. Conclusion The association between radon and kidney cancer remains unclear but cannot be excluded because of its biological plausibility and the limited number and quality of existing studies. Additional data from the general population and well-designed miner cohort studies are needed to reveal the real relationship between radon exposure and kidney cancer.

在炭纤维生产线上对某国产聚丙烯腈(PAN)原丝进行预氧化处理,采用差示扫描量热法(DSC)对该国产聚丙烯腈原丝进行热分析,确定预氧化温度,采用元素分析仪、傅里叶转换红外光谱仪(FTIR)和X线衍射仪(XRD)等检测方法对不同预氧化阶段的纤维进行研究。研究结果表明:随着预氧化温度的升高,纤维的密度逐渐增加,最终密度达到1.366 g/cm3;纤维的含氧量随温度的升高而增加,且温度越高,增加越快,而其他元素变化缓慢;FTIR结果显示2 243.1 cm-1(C≡N)振动峰逐渐降低,新出现的1 612.2 cm-1(C=N)振动峰逐渐加强,表明纤维内线性分子链向耐热的梯形结构转变;X线衍射结果显示17°和29°附近的衍射峰强度逐渐减小,由较宽的衍射峰替代,表明纤维内发生收缩解取向,原序态结构消失,形成堆积较混乱的且不规则的梯形聚合物。

AIM： To determine the role of Fas/Fas ligand （FasL） in the immune escape of colon cancer cells. METHODS： Immunohistochemistry was used to observe the expression of Fas and FasL in the tissues of colon cancer patients. In situ hybridization was used to detect the localization of FasL mRNA expression in cancer tissues. Terminal deoxynucleotide transferase-mediated dUTP nick end labeling （TUNEL） assay and CD45 staining were performed to detect the apoptosis of tumor-infiltrating lymphocytes （TILs）. Co-culture assays of colon cancer cells （SW480） and Jurkat cells （Fas-sensitive cells） were performed to observe the counterattack of colon cancer cells to lymphocytes. RESULTS： Of 53 cases of colon carcinomas, 23 cases （43.4%） expressed Fas which was significantly lower as compared to the normal colonic mucosa （73.3%, P〈0.01）, and 45 cases （84.9%） of colon carcinomas expressed FasL, whereas only two cases （3.75%） in normal mucosa expressed FasL. FasL expression in the colon cancer cells was found to be associated with increased cell death of TIEs. The apoptotic rate of TIL in the FasL-positive staining regions of tumor cells was significantly higher than that in the FasL-negative staining region （54.84±2.79% vs 25.73±1.98%, P〈0.01）. The co-culture of SW480 cells and Jurkat cells confirmed the function of FasL on the SW480 cells. The apoptotic rates of Jurkat cells were found to be related with the amount of SW480 cells. CONCLUSION： Colon cancer cells can escape the immune surveillance and killing via decreasing Fas expression, and can counterattack the immune system via increasing FasL expression. Fas/FasL can serve as potential targets for effective antitumor therapy.
