AIM To investigate the association between serum human epidermal growth factor receptor 2(HER2) extracellular domain(ECD) and tissue HER2 status, and the prognostic value of serum HER2 ECD in patients with gastric *** A total of 239 patients with gastric cancer were enrolled from December 2012 to June 2013. Serum HER2 ECD was determined by chemiluminescent assay, and tissue HER2 status was evaluated by immunohistochemistry and fluorescence in situ hybridization assay. A receiver operating characteristic(ROC) curve was plotted to identify the optimal cut-off value for serum HER2 ECD assay for predicting survival in gastric cancer *** Serum HER2 ECD was significantly correlated with tissue HER2 status(P < 0.001), tumor size(P < 0.001), and intestinal type of gastric cancer(P =0.021). Serum HER2 ECD levels differed significantly between patients with HER2-positive tissue expression and those with HER2-negative tissue expression. ROC analysis yielded an area under the curve value of 0.79(95%CI: 0.71-0.87, P < 0.001), with a sensitivity and specificity of 0.54(95%CI: 0.37-0.70) and 0.93(95%CI: 0.88-0.96), respectively. With a cut-off value of 24.75 ng/m L, high serum HER2 ECD had a negative impact on overall survival of the patients(HR: 1.93, 95%CI: 1.32-4.38, P = 0.006). CONCLUSION Serum HER2 ECD could be a highly specific surrogate biomarker for tissue HER2 status in gastric cancer. Optimal cut-off criteria for predicting survival should be established.

碳纤维基复合材料(CFC)因其优异的力学性能而受到广泛关注,广泛应用于航空航天、交通运输、军工等各个领域。然而,对碳纤维基复合材料光电转换的潜在机制和影响因素的研究却很少。本研究采用选择性激光烧结法制备了碳纤维增强聚酰胺12(CF/PA12)复合材料。结果表明,当碳纤维质量分数为15%时,CF/PA12复合材料具有良好的光热转换和焦耳加热特性。随着太阳强度的增加,CF/PA12复合材料的温度逐渐升高,当CF/PA12平行于光向取向时温度达到最高。本研究还证明了CF/PA12纤维取向对材料电阻和热阻的选择性调节。设计了一种集成光热转换的电压连续可调模式,并通过可循环试验进行了验证。本研究结果拓展了碳纤维增强聚合物复合材料在温度调节和操作控制方面的应用。

以堇青石为原料,采用“分步制备、整体组装、一次烧结”的方式制备了比表面积大且能够减缓堵塞的新型气泡发生器。考察了单一粒径及复合粒径聚苯乙烯(PS)微球对气泡发生器的基本性能及发泡性能的影响,并讨论两种粒径类型的PS微球对材料孔隙率的影响机理。结果表明:添加复合粒径PS微球试样的内部,孔棱上分布着更多微观小孔且宏观大孔在烧结过程中引起的体积收缩更小,这是引起材料孔隙率更高的主要原因。复合粒径造孔剂试样能产生更多的微细气泡,但气泡粒径分布范围变宽、平均尺寸变大。当复合粒径为5/10μm时,试样基本性能良好,产生的气泡数量较多且气泡平均尺寸仅有25.86μm,能很好地满足气浮要求。
