Objective To investigate the characteristics of diet in patients with gestational diabetes mellitus(GDM) and analyze their dietary nutrition.Methods Clinical data of 978 cases of pregnant women in our hospital were collected and divided into GDM group(458 cases) and the healthy control group (520 cases).Dietary questionnaire was designed and diet characteristics were analyzed retrospectively.Daily calories and nutrients intake were calculated by software calculation.Results There were significant differences on the dietary pattern between the two groups:daily coarse grains:(35.12 ±4.87) g vs (46.35 ±5.23) g;seafood:(22.10 ± 8.45) g vs (39.34 ± 12.45) g;grilled:(6.72 ± 1.76) g vs (3.45 ±0.34) g;fried:(25.34 ± 7.84)g vs (10.56 ±4.76) g;sausage:(5.38 ± 1.81) g vs (3.45 ± 0.45) g;dessert type products intake:(50.41 ±20.76) g vs (35.86 ± 10.45) g (t =2.582,10.346,15.452,20.239,18.195,8.472,respectively,P ＜0.05).There was only significant difference between the two groups on calcium supplements in daily intake of nutritional supplements(GDM group 43.89％,control group 72.69％,x2 =83.660,P ＜ 0.001),and there was no significant difference on the rests(all P ＞ 0.05).Vitamin A,B1,B2,C and calcium,iron,zinc,selenium daily intake in GDM patients were less than those in the control group,but there was significant difference only in calcium compared with the control group (GDM group (785.2 ± 194.5) mg,control group (945.5 ± 245.2)mg,t =2.795,P =0.005).Multivariate logistic regression found that excessive intake of fried class (OR =3.357,95％ CI =2.012-11.340),barbecue (OR =2.652,95％ CI =1.834-8.578),sausage type products (OR =2.518,95％ CI =1.743-7.421) etc.were dietary factors of GDM (all P ＜ 0.05).Incidence of GDM was significantly increased if taking more.While the increased intake of coarse grains (OR =0.632 95％ CI =0.134-1.489),seafood class(OR =0.408,95％ CI =0.105-1.189) can reduce the occurrence of GDM(all P ＜ 0.05).Conclusion Many unscientific ways of eating involved in pregnant women with GDM.Dessert,sausage,grilled,fried products intake increased the risk factors for GDM.Coarse grains,seafood intake were the protective factors of GDM.Timely adjustment of maternal diet and adequate calcium supplementation played an important role in the prevention of GDM.

Objective To investigate the effect of multidisciplinary diagnosis and treatment including ex-utero intrapartum treatment (EXIT) procedure to improve the prenatal survival rate of fetus with neck mass.Methods Multidisciplinary diagnosis and treatment model were carried out in four pregnancy women with fetal neck mass from September 2007 to February 2010.The model included prenatal assessment and monitoring,EXIT procedure during cesarean section,neonatal reassessment and surgical treatment by the cooperation of obstetricians,neonatologists,children surgeons,sonographers and anesthetists.Results All patients underwent cesarean section after 37gestational weeks.Mean delivery time was 37+4 weeks (37-38+3 weeks); mean birth weight was 2972 g (2600-3250 g); mean operation time was 4 min (2-7 min).The gestational age of primary diagnosis of fetal neck mass was 24-34 gestational weeks.After delivery,the size of neck mass was from 3.0 cm × 2.0 cm × 1.0 cm to 6.2 cm× 5.8 cm × 6.8 cm.The tracheal compression and displacement were found by color doppler ultrasound scan and magnetic resonance imaging in all cases.Two of them were completed with polyhydramnios and the others with normal volume of amniotic fluid.EXIT procedure was successfully carried out during cesarean section.Neonatal reassessment showed the trachea of three infants were obviously compressed and lapsed by enhanced CT; the infants relied on mechanical ventilation after birth and underwent operation on day 6 to 8.Tracheal impression was not presented in one infant and trachea cannula was removed on the second day,operation was not performed.All of those infants had good outcomes.Conclusions The multidisciplinary diagnosis and treatment model,including EXIT procedure,is a safe,efficient and feasible strategy,which is necessary for fetus with neck mass.
