RESUMO

Objective To explore the risk factors of gestational diabetes mellitus and its influence on pregnancy outcome,and to provide guidance for early intervention of gestational diabetes to improve pregnancy outcome in clinic.Methods Totally 159 patients with gestational diabetes mellitus in our hospital from January 2014 to January 2016 as observation group were collected,and at the same time,634 healthy pregnancy women as control group were collected.The risk factors of gestational diabetes mellitus were analyzed by the Logistic regression analysis and comparison of pregnancy outcome between two groups was conducted.Results The patients in the observation group with age ≥ 35 years,overweight or obesity before pregnancy,adverse pregnancy history,family history of diabetes,hypertension and vaginal candida and thyroid peroxidase antibody (TPOAb) compared with the control group,the difference was statistically significant (P < 0.05).Multivariate logistic regression analysis showed that age ≥ 35 years,overweight or obesity before pregnancy,adverse pregnancy history,family history of diabetes,and positive TPOAb were the independent risk factors of gestational diabetes mellitus,OR was 2.441,2.889,1.486,4.879,and 1.323,respectively;the difference was statistically significant (P < 0.05).The incidence of premature rupture of membrane,pregnancy hypertensive disorder,premature birth,polyhydramnios,uterine-incision and postpartum hemorrhage in observation group were higher than those in control group,the difference was statistically significant (P < 0.05).The incidence of giant baby,fetal distress and mild neonatal asphyxia were higher than those in control group,and the difference was statistically significant (P < 0.05).No statistical significance in fetal growth restriction,neonatal malformations between two groups was found (P > 0.05).Conclusions Age ≥35 years,overweight or obesity before pregnancy,adverse pregnancy history,family history of diabetes,and thyroid dysfunction were the independent risk factors of gestational diabetes mellitus,and it has serious effect on pregnancy outcome,so that it should take measures to prevent the independent risk factors.

RESUMO

The inclusion compound of amylose and salicylic acid (SA) was prepared by a sealed temperature control method, and the formation of the inclusion compound was confirmed by IR spectrum and powder X-ray diffraction. The kinetic parameters of dissociation of amylose/SA compound were studied by the nonisothermal method which was defined as a relationship between the dissociation ratio and time. The values of activation energy (Ea) and frequency factors (InA) were calculated by a nonlinear least-square method. In this study, the formation of the inclusion compound of amylose/SA was confirmed by IR spectrum powder X-ray diffraction. SA existed in a molecule form in the spiral stouction of amylose. The dissociation of amylose/SA compound was attributed to first order reaction. The values of Ea calculated by the nor-isothermal method were 21.71 and 22.41 kJ x mol(-1) at heating rate 5 and 10 degrees C x h(-1), respectively. The corresponding isothermal method value of Ea was 22.17 kJ x mol(-1); the calculated InA values were 9.32 and 10.08 at heating rate 5 and 10 degrees C x h(-1), respectively. The corresponding isothermal method lnA value was 9.26. The results were in good agreement with Ea values and lnA values by isothermal method. These results indicated that the non-isothermal method described in this study could be adequately used for the stability study of inclusion compound and was a rapid and accurate method for the determination of kinetic parameters.
