目的：探讨妊娠期糖尿病（GDM）孕妇血浆甘露糖结合凝集素（MBL）及内毒素（LPS）水平变化及其与体质指数（BMI）的关系。方法：纳入新诊断的GDM组孕妇及正常组孕妇各45例，测定血浆MBL、LPS浓度；每组按BMI（25 kg／m2）为界分为肥胖亚组（BMI ≥25 kg／m2）和非肥胖亚组（BMI ＜25 kg／m2），分析GDM组孕妇血浆MBL、LPS水平变化及其与BMI的相关性。结果：GDM组MBL浓度低于正常组，而LPS浓度明显高于正常组，差异具有统计学意义（P ＜0．05）；Pearson相关性分析显示GDM孕妇血浆BMI与MBL呈负相关（r ＝－0．28，P ＜0．05），BMI与LPS呈明显正相关（r ＝0．62，P ＜0．05）；LPS与MBL呈负相关（r ＝－0．43，P ＜0．05）。正常组MBL、LPS与BMI之间的这种相关性不存在。结论：MBL和LPS可能是超重孕妇GDM发病的两个重要危险因素，对临床GDM防治可能具有重要意义。%Objective To explore the relationship between plasma mannose-binding lectin (MBL), lipopolysaccharide (LPS) and body mass index in pregnant women with gestational diabetes mellitus (GDM). Methods 45 newly diagnosed GDM pregnant women and 45 healthy women (control group) were selected in this study. Plasma concentration of MBL and LPS were measured. All the groups were sub-divided into obesity (BMI ≥ 25 kg/m2) and non-obesity (BMI < 25 kg/m2) subgroup. The relationships of levels of plasma LPS, MBL with BMI were analyzed. Results The level of plasma MBL in GDM group was significantly lower than that in control group(P < 0.05), while the concentration of LPS in serum was much higher than that in healthy pregnant women (P < 0.05). Pearson analysis showed the level of MBL in GDM group was negatively correlated with BMI(r=-0.28, P<0.05), serum LPS concentration was positively correlated with BMI(r = 0.62, P < 0.05) and LPS was negatively correlated With MBL(r = -0.43, P < 0.05) . The above correlations were not found in control group. Conclusion Serum MBL and LPS maybe two important risk factors for those pregnant women being overweight, and could offer great significance for the prevention and treatment of GDM.
