The results show that the obtained nanoscale zero valent iron particles are mostly in spherical shape with less than 100 nm in size. The acid fuchsine can be removed by nanoscale zero valent iron particles efficiently. The efficiency of removing acid fuchsine from solution is increased with increasing temperature and the dosage of nanoscale zero valent iron particles and decreasing initial concentration of acid fuchsine. The mechanism of removing acid fuchsine by nanoscale zero valent iron particles may include dual functions of absorption and degradation, and the degradation may play a major role in the reaction.

研究结果表明：纳米零价铁颗粒为球形，单个颗粒粒径小于100 nm；纳米零价铁对酸性品红有很好的脱除作用，酸性品红的脱除率随温度的升高、纳米零价铁用量的增加以及酸性品红初始浓度的降低而逐渐增大；纳米零价铁对酸性品红有吸附和降解的双重作用，而以降解作用为主。

Results and conclusion: The expression of NF-κB p65,TNF-α and IL-8 was higher than that of other groups.They may play a vital role in parturiens with PRD associated with IAI .In the placenta tissues of the mice with PRD associated with simulating IAI, after an application of PDTC, TNF-α and IL-8 decreased and the gestion time could maintain longer.

实验主要结果与结论如下：1、通过检测足月妊娠和早产胎盘组织中NF-κB和细胞因子的表达，发现在感染性早产时，NF-κB和细胞因子TNF-α、IL-8的表达增加，提示NF-κB可能为感染性早产分娩启动的关键环节，炎性细胞因子TNF-α与IL-8在感染性早产中起重要作用。
