【目的】探讨妊娠期糖尿病（GDM）孕妇产后糖尿病发生的高危因子。【方法】选择2015 年1 月至 2015年12月在北京大学深圳医院规律产检并分娩的单胎妊娠期糖尿病孕妇342例，所有孕妇在孕24~28周均直 接行75 g 葡萄糖耐量试验（OGTT）。根据空腹、1 h和2 h血糖值，将仅有一项血糖指标异常的记为GDM Ⅰ（219 例），二项异常的为GDM Ⅱ（81例）和全部异常的为GDM Ⅲ（42例）。以同期在本院规律产检，血糖值正常并分 娩的968例孕妇设为对照组。所有研究对象均排除家族糖尿病史、产科并发症和其他内科并发症等高危因素。 所有受试对象于分娩后一年，再次行OGTT 试验，分析比较各组孕妇妊娠期各时间点血糖及糖化血红蛋白 （HbA1c）等高危因子与产后糖尿病发生的相关性分析。【结果】复查结果显示，342名GDM孕妇中有27名产后 发生2型糖尿病，发病率高于对照组，差异有统计学意义（P < 0.05），其中GDM Ⅲ组中发病率为45.23%，发病率 高于其他GDM组（P < 0.05）；在发生2型糖尿病的GDM孕妇中，与自身妊娠前和同期未发生2型糖尿病的GDM 孕妇相比，2 h血糖和HbA1c值明显增加，且差异具有统计学意义（P < 0.05）。Logistic回归分析结果显示，GDMⅢ 组别、2 h血糖和HbA1c值，这三种高危因子均是GDM孕妇发生2型糖尿病的危险因素（P < 0.05）。【结论】OGTT 血糖全部异常的GDM孕妇产后发生2型糖尿病的发病率明显增加。临床上应对这类孕妇的血糖进行动态的监 控，及时发现并纠正2 h血糖和HbA1c值的异常。

During the long-term use process of triethylene glycol in Jingbian Gasfield, solution quality has been declined because of the accumulation of formation water impurities, pipeline corrosion products and solution degradation products, which affected the absorption and regeneration performance of triethylene glycol solution. The effective components of triethylene glycol solution, the type and content of the impurities in the solution were detected qualitatively and quantitatively. Experiments and process conditions optimization aiming at single solution purification method were carried out. According to the result of purification, different purification processes were combined. The combination process of quartz sand filtration + actived carbon decoloration + ion exchange resin was selected to purify the triethylene glycol solution of Jingbian Gasfield. The concentration of suspended solids and salt ions reduced significantly by optimized combination purification process. Meanwhile, purified triethylene glycol was used in dehydration of gas gathering station. It turned out that purified solution had good dehydration effect, which could meet the production requirements. [ABSTRACT FROM AUTHOR]
