Objective To determine the relationship between maternal negative major life events during the first trimester and incidence of congenital heart diseases(CHD) in their offspring.Methods The 4-2-1 medical information was referred and screen CHD children who were confirmed by Municipal hospitals over.A 1:2 case-control study was carried out with face-to-face structured interviews and telephone interviews to investigate parents of 116 children with CHD and 232 healthy matched children,including the parents′ demographic variables(such as whether the working environment exposure to toxic and hazardous substances 1 year before pregnancy,et al),mother′s experience of previous adverse pregnancy,duration of pregnancy condition(such as maternal negative major life events during the first trimester,the history of catching a cold or fever during the first trimester.The possible risk factors were analyzed by simple factors Logistic regression methods.Then,diagnosing the colinearity among these suspicious risk factors,and rejecting it if necessary.Finally,multiple factors conditional Logistic stepwise regression was used to filter once more.Results The results revealed that maternal negative major life events and taking medicine during the first trimester,mother′s experience of previous adverse pregnancy were related to the occurrence of CHD in the offspring.Moreover,maternal negative major life events during the first trimester play the most important role(OR=1.810).Conclusions Strengthening mothers′ mental health and controlling or reducing maternal negative major life events during the first trimester may be effective in reducing the risk of CHD.

Advanced in medical and surgical management have led to reduce mortality in children with congenital heart disease(CHD).However,more recent and ongoing research had been focused on neurodevelopmental outcome.With the improved survival in children follo-wing surgery for cardiac malformations,increased emphasis had being placed on neurological sequelae,especially on cognitive function.Car-diac surgery couldn't correct cognitive disorder,more and more findings suggested that the cognitive disorder of CHD might be the result of utero injury.J Appl Clin Pediatr,2009,24(1):61-64

Objective To explore whether obese adolescents had neurochemical abnormalities in frontal lobe and hippocampus.Methods Anthropometric indicators were measured in all participants.Proton magnetic resonance spectroscopy(1H-MRS)were performed in 9 obese adolescents and 9 non-obese children as controls.Spectral peaks of N-acetylaspartate(NAA),creatine(Cr),choline(Cho)of 2 cortexes were measured and their ratios were computed and compared.Results Values of NAA and Cho in frontal lobe in obese group were significantly lo-wer than those of controls.There was no significant difference of Cr,NAA/Cr,Cho/Cr in frontal lobe and hippocampus between 2 groups.Conclusion The reduced NAA and Cho on 1H-MRS suggests that amount of neural nerve and myelination of white matter may be harmed in frontal lobe of obese adolescents.

AIM:To investigate the expression of poly(ADP-ribose) polymerase-2 (PARP-2) during rat car-diac hypertrophy in vitro and in vivo, and to explore the effects of PARP-2 on the cardiac hypertrophy.METHODS:Ab-dominal aortic coarctation ( AAC) was performed to establish a model of pressure overload-induced cardiac hypertrophy in SD rats.The expression of PARP-2 at mRNA and protein levels in the myocardium was determined by real-time PCR and Western blot.The hypertrophy model of the cardiomyocytes was induced by treating the cells with angiotensinⅡ( AngⅡ) . PARP-2 was knocked down by siRNAs in neonatal rat cardiomyocytes and the cardiomyocyte hypertrophy was evaluated by measuring the mRNA levels of ANF, BNP, and β-MHC and the cellular surface area.RESULTS: The expression of PARP-2 at mRNA and protein levels was both increased in the AAC rats as compared with those in the sham animals.The expression of PARP-2 at mRNA and protein levels was also increased in a time-and concentration-dependent manner in AngⅡ-induced hypertrophy model of the cardiomyocytes.In the neonatal rat cardiomyocytes, knockdown of PARP-2 ex-pression by siRNA attenuated AngⅡ-induced cardiac hypertrophy of the cardiomyocytes, indicating that endogenous PARP-2 played a positive regulatory role in cardiac hypertrophy.CONCLUSION:The mRNA and protein levels of PARP-2 in-crease in the in vitro and in vivo models of cardiac hypertrophy.Knockdown of PARP-2 protects cardiomyocytes from hyper-trophy.
