Association between maternal gestational diabetes mellitus and the risk of autism spectrum disorder in offspring / 中国当代儿科杂志

OBJECTIVES@#To explore the association between maternal gestational diabetes mellitus (GDM) exposure and the development of autism spectrum disorder (ASD) in offspring.@*METHODS@#A case-control study was conducted, recruiting 221 children with ASD and 400 healthy children as controls. Questionnaires and interviews were used to collect information on general characteristics of the children, socio-economic characteristics of the family, maternal pregnancy history, and maternal disease exposure during pregnancy. Multivariate logistic regression analysis was used to investigate the association between maternal GDM exposure and the development of ASD in offspring. The potential interaction between offspring gender and maternal GDM exposure on the development of ASD in offspring was explored.@*RESULTS@#The proportion of maternal GDM was significantly higher in the ASD group compared to the control group (16.3% vs 9.4%, P=0.014). After adjusting for variables such as gender, gestational age, mode of delivery, parity, and maternal education level, maternal GDM exposure was a risk factor for ASD in offspring (OR=2.18, 95%CI: 1.04-4.54, P=0.038). On the basis of adjusting the above variables, after further adjusting the variables including prenatal intake of multivitamins, folic acid intake in the first three months of pregnancy, and assisted reproduction the result trend did not change, but no statistical significance was observed (OR=1.94, 95%CI: 0.74-5.11, P=0.183). There was an interaction between maternal GDM exposure and offspring gender on the development of ASD in offspring (P<0.001). Gender stratified analysis showed that only in male offspring of mothers with GDM, the risk of ASD was significantly increased (OR=3.67, 95%CI: 1.16-11.65, P=0.027).@*CONCLUSIONS@#Maternal GDM exposure might increase the risk of ASD in offspring. There is an interaction between GDM exposure and offspring gender in the development of ASD in offspring.

Changes in Metabolism and Function of Platelets Stored at Different Temperature / 中国实验血液学杂志

@#AAbstractObjective:To compare and analyze the metabolic and functional changes in platelets stored at 4 ℃ and ones stored at 22 ℃ with agitation so as to provide an experimental basis for the cryopreservation technology of platelets.@*METHODS@#Samples were collected from platelets stored at 4 ℃ in 2, 4, 6, 11, 15 and 21 days, and from ones stored at 22 ℃ with agitation during the same days, the metabolism indicators and thromboelastogram (TEM) were analysed.@*RESULTS@#In metabolism, there were no significant changes of pH, GLU，PCO2, PCO2 and MPV levels of platelets stored at 4 ℃ for <6 days (P＞0.05), However, the Plt count decreased, the PDW and LDH level incrseased (P＜0.05). At the same time, only MPV had no changes of platelets stored at 22 ℃ during above-mentioned same days (P＞0.05), while the pH, PCO2, GLU, Plt all decreased, and PO2, LDH, PDW incrseased (P＜0.05). There were significant changes about the pH value, PO2, Plt, MPV, LDH, GLU levels between the two kinds of stored platelets during the same storing period (P＜0.05). The pH value and MPV of platelets stored at 4 ℃ were obviously lower than ones stored at 22 ℃, while GLU, PO2, LDH and Plt levels showed reverse changes (P＜0.05). Meanwhile, the PCO2 of platelets stored at 4 ℃ not could be detected and the Plt count reduced rapidly from d15. In function, the MA level of platelets stored at 4 ℃ was slower than that of platelets stored at 22 ℃, that is, the MA level of platelets stored at 4 ℃ were higher than that of platelets stored at 22 ℃ during the same storeing period (P＜0.05).@*CONCLUSION@#Platelets stored at 4 ℃ have much slower metabolism than ones stored at 22 ℃, and the aggregation is stronger of platelets stored at 4 ℃ than that of ones at 22 ℃ during the same conservation period.
