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.

Objective To investigate the clinical features and distribution of G types of rotavirus diarrhea in infants and children in Suzhou and Maanshan areas.Methods 1267 stool specimens were collected from children under 5 years with acute diarrhea. Enzyme-linked immunosorbant assay (ELISA) and nested polymeras chain reaction (Nested-PCR) were used to detect rotavirus and serotypes.Results In 1267 stool specimens, 378 were detected RV positive, and serotype G was the prevalent type in the two cities with number of 250 and the G3 and G1 types were the most prevalent which accounted for 40%(100/250) and 44.40 % (111/250), respectively. While the G2 ,G4, G9 types and mixed infections were 8,3,3,4 and the un-identified type was 8.40%(21/250). G1 type was the most prevalent in Maanshan are which accounted for 58.54% in all cases,while the G3 type accounted for the most of case(47.85%) in Suzhou area.Conclusions The results indicated that rotavirus was the most important etiologic agent in Maanshan and Suzhou areas,G1 and G3 were the most prevalent types,respectively.
