The results show that, after oxidation treatments, interfacial properties between CF and non-polar polyarylacetylene （PAA） resin are remarkably modified by removing weak surface layers and increasing fiber surface roughness. Coating treatment by high char phenolic resin solution after oxidation makes interface of CF/PAA composites to be upgraded and the interfacial properties further bettered.展开更多
目的比较扫描式葡萄糖监测(FGM)及自我血糖监测(SMBG)在妊娠合并糖尿病患者中的应用效果。方法选择患者70例,分为妊娠期糖尿病(GDM)组及2型糖尿病(T2DM)妊娠组,行14 d FGM,每日行7次SMBG;对比2种方法的血糖最大值、最小值、平均值并行...目的比较扫描式葡萄糖监测(FGM)及自我血糖监测(SMBG)在妊娠合并糖尿病患者中的应用效果。方法选择患者70例,分为妊娠期糖尿病(GDM)组及2型糖尿病(T2DM)妊娠组,行14 d FGM,每日行7次SMBG;对比2种方法的血糖最大值、最小值、平均值并行相关性分析;比较2组目标范围时间及低葡萄糖事件。结果GDM组SMBG、FGM血糖最大值及平均值均显著低于T2DM妊娠组(P<0.05);2组SMBG、FGM最小值比较,差异无统计学意义(P>0.05)。GDM组和T2DM妊娠组患者SMBG与FGM最大值、平均值呈正相关(r值分别为0.88、0.96和0.72、0.89,P<0.05),FGM与SMBG最小值无相关性(r值分别为0.22、0.19,P>0.05)。GDM组目标范围时间高于T2DM妊娠组,GDM组低葡萄糖事件低于T2DM妊娠组(P<0.05)。结论SMBG和FGM均能准确反映妊娠合并糖尿病患者血糖水平;FGM对于夜间低血糖、无症状低血糖及血糖波动的监测优于SMBG。展开更多
