Objectives This study was designed to observe the correlation of the levels of serum N-terminal pro-brain natriuretic peptide(NT-proBNP) and high sensitivity C-reactive protein(hs-CRP) between the 3rd day after acute myocardial infarction(AMI) and after 3 months of left ventricular remodeling(LV remodeling) and to establish the predictive levels of NT-proBNP,hs-CRP for LV remodeling after AMI.Methods The blood samples from 106 patients with the first AMI and echocardiography were examined on the 3rd day and after 3 month.LV remodeling was estimated by the changes of left ventricular end-diastolic volume(LVEDV) during the 3rd day and after 3 month.Based on the change of LV remodeling,the 106 patients were divided into two groups:LV remodeling group(defined as the change rate of LVEDV more than 20%) and non-LV remodeling group.Results The correlation coefficients of the change of LVEDV were 0.706 for serum NT-pro BNP and 0.596 for hs-CRP.With a cutoff value of 0.20,the area under the ROC curve(AUCs) was(0.892) for NT-proBNP and 0.825 for hs-CRP.There was no statistically difference between NT-proBNP and hs-CRP.The ROC plot indicated that NT-proBNP was superior to hs-CRP for predicting LV remodeling.Conclusion The level of serum NT-proBNP appropriately reflects LV remodeling after AMI and shows more efficacious than the level of serum hs-CRP.The level of serum NT-proBNP on the 3rd day after AMI and LV remodeling were positively correlated with the level after 3 months.

Objective To investigate the changes of plasma free carnitine (FC) concentrations in preterm infants supplemented with L-carnitine, and to provide a reference for routine preterm infants L-carnitine supplements. Methods A total of 99 preterm infants supplemented with 10 mg/(kg·d) L-carnitine on days 2 and 5 after birth, and 65 full term infants from Department of Neonatology, the Fifth People′s Hospital of Dongguan during July 2014 to December 2015 were recruited in this study , and filter-paper blood spots were collected by heel prick on days 1, 3 and 7. FC was measured using electron spray ionization (ESI) tandem mass spectrometry (MS-MS). Results Concentrations of FC decreased steadily from day 1 to day 7 in full term infants , while it remained the same level during the first week after birth as at birth. Additionally, concentrations of FC were significantly higher in preterm infants than full term infants on day 1 after birth. Conclusions The reasonable L-carnitine supplements may keep the levels of plasma FC at the levels at birth , which is important for fatty acid metabolism in preterm infants.

ObjectiveTo evaluate the accuracy and value of the ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of agenesis of the corpus callosum in the newborns.MethodsConventional cerebral ultrasound screening was performed in 8086 newborns admitted to NICU in our hospital from January 2012 to June 2014 and agenesis of the corpus callosum was suspected or conifrmed in 31 newborns. The diagnostic accuracy of ultrasonography was assessed through the com-parison between the results of ultrasonography and MRI.ResultsIn 31 cases with suspected agenesis of the corpus callosum, ultrasonography showed 14 cases of complete agenesis of which 13 cases had the same diagnosis with MRI except one case of partial agenesis, meanwhile, ultrasonography showed 16 cases of partial agenesis of which 15 cases had the same diagnosis with MRI except one case of complete agenesis. One case of abnormal corpus callosum determined by ultrasonography was diagnosed as partial agenesis by MRI. MRI showed there were other brain malformations in 14 cases.ConclusionsUltrasonography and MRI has a high consistency in the diagnosis of agenesis of the corpus callosum in neonates, so the former can be used as a routine screening and the latter can be used as a method of accurate diagnosis. A combination of both has an important role in early diag-nosis and clinical evaluation.
