Objective To investigate the iron status in the newborns of maternal gestational diabetes mellitus(GDM) women,and explore the mechanism of iron deficiency in these newborns.Methods From June 2008 to October 2011,64 GDM women (GDM group) and 71 healthy pregnant women (control group)who delivered in the Second Affiliated Hospital of Wenzhou Medical College and their newborns were studied prospectively.Serum ferritin (SF),serum transferrin receptor (sTfR),erythropoietin (Epo),haemoglobin (Hb),serum level of insulin and plasma glucose in cord blood was measured.The neonatal birth weight (BW) and birth weight Z Score(WAZ) was recorded.The concentrations of serum fasting insulin (FINS),fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1c)were tested for all the women before delivery.Results In the GDM group,the cord blood sTfR,Epo and serum level of insulin was (42 ± 10)nmol/L,(56 ±41) U/L and(18 ± 5) U/L,respectively.While in the control group,these were(35 ± 8)nmol/L,(41 ± 43) U/L and (10 ± 5) U/L,respectively.The cord blood sTfR,Epo and serum level of insulin in the GDM group were significantly higher than those in the control group (P ＜ 0.05).The cord blood SF in the GDM group[(60 ±36) μg/L] was significantly lower than that of the control group[(146 ±38) μg/L,P ＜ 0.01].The neonatal BW and WAZ in the GDM group [(3615 ± 538) g and 0.558] were significantly higher than those in the control group [(3449 ± 423) g and 0.224,P ＜ 0.05].No significant difference was found in the cord blood plasma glucose and Hb between the GDM group[(3.3 ± 1.0) mmol/L and (181 ± 18) g/L] and the control group [(3.0 ± 0.8) mmol/L and (176 ± 16) g/L,P ＞ 0.05].The FINS and HbA1c of the GDM group[(12.5 ±5.0) U/L and (6.5 ±0.7)％] were significantly higher than those in the control group [(10.9 ± 4.3) U/L and (5.3 ± 0.7) ％,P ＜ 0.05].The FPG of the GDM group and the control group were (5.3 ± 1.2) and (5.0 ± 1.0) mmol/L,respectively,with no statistically significant difference (P ＞ 0.05).Conclusion Maternal GDM may related to the iron deficiency of the newborns.

Objective To investigate the anti-inflammatory and analgesic effects of toothache drop pills. Methods The acute inflammatory models such as xylene-induced ear edema and egg white-induced paw edema and the chronic inflammatory model granuloma induced by cotton pellet implantation were used in researching the inflammatory effects of toothache drop pills. Meanwhile, the analgesic effects of toothache drop pills were observed by hot plate and acetic acid writhing test. Results Compared with the blank control group,the degree of ear swelling in mice in the positive control group, toothache drop pills middle and high dose group (2.56 ± 1.35 mg, 4.26 ± 1.21 mg, 3.23 ± 1.25 mg vs. 8.25 ± 1.21 mg) were lower than the blank control group (P<0.05). 120 minutes after administration,compared with the blank control group, the degree of paw swelling in mice in the positive control group, toothache drop pills middle and high dose group (23.54 ± 9.12 mg, 27.58 ± 9.14 mg, 21.25 ± 8.45 mg vs.39.54 ± 8.89 mg) were lower than the blank control group (P<0.05). Granuloma swelling quality in mice caused by cotton in the positive control group, toothache drop pills middle and high dose group (6.51 ± 2.58 mg, 7.82 ± 1.57 mg, 6.58 ± 3.47 mg vs. 13.58 ± 3.25 mg) were lower than the blank control group (P<0.05). The threshold of pain in mice in the positive control group, toothache drop pills middle and high dose group (20.86 ± 2.58 s, 20.25 ± 2.14 s, 20.75 ± 1.78 s vs.17.21 ± 3.31 s) were increased (P<0.05). The number of mice writhing in the positive control group, toothache drop pills middle and high dose group (23.47 ± 7.57, 28.65 ± 6.54, 24.36 ± 7.78 vs. 40.96 ± 6.58) were decreased(P<0.05). Conclusion Toothache drop pills had obvious anti-inflammatory and analgesic effects.
