Objective To study on the neural mechanism of deficits in Chinese developmental dyslexia from the aspects of the phonological processing,orthographic skills,visual magnocellular function and cerebellum function.Methods Critical words in Chinese and English (e.g.dyslexia,reading development,Chinese,neural) and formula (e.g.Chinese and (reading development) and (neural or neuroimage or fMRI or ERP or brain area) related with the present topic were searched among the article abstracts in Chinese and foreign databases (e.g.CNKI,Pubmed,Sciencedirect) from July to December,2014.Results Fifty-two relevant articles were gained access to the database.Referring to the present topic,research on the neural mechanism of dyslexia with neuroimaging technique was reserved,while the studies in which the reading impairment of the participants was caused by acquired factors were eliminated.Finally,thirty-three valid articles were retained.Conclusion According to previous studies,although there might be similarities in cognitive deficits of dyslexia between alphabetic languages and Chinese,it was still found that the Chinese children with developmental dyslexia exhibited abnormal neural activities and impaired brain structures in areas associated with Chinese phonology (i.e.left middle frontal gyrus,which was different from the left inferior fiontal gyrus always related with phonological processing in alphabetic languages) and orthographic skills (right occipitotemporal areas which was responsible for the visuospatial processing),revealing language specificity of Chinese to some extent.However,some other studies reported the similarities in neural mechanisms of dyslexia across languages.Therefore,more studies were required to further examine the crosscultural mechanism of the neural activity regarding the developmental dyslexia.Meanwhile,researches on the aspects of general perception showed Chinese dyslexic individuals had deficits in visual magnocellular function,and cerebellum.Future studies were required to explore the relationship between the linguistic and non-linguistic deficits.

ObjectiveTo establish the mathematical model of transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) after phototherapy in neonates.MethodsNeonates with pathological jaundice were enrolled from October 2013 to June 2014. The neonates were divided into three groups by gestational age: full-term neonates (gestation age of 37-42 weeks), late preterm neonates (gestation age of 34-36+6 weeks), early and mid-preterm neonates (gestation age of 28-33+6 weeks). The neonates received single or double sided phototherapy. During the phototherapy, the forehead and chest were covered by opaque material. The TcB was measured at forehead, mid sternum, perineum area three times each before and after phototherapy. Mean-while the TSB was tested.Results Two hundred and sixty-one neonates with hyperbilirubinemia were enrolled, among whom there were 169 full-term neonates, 63 late preterm neonates and 29 early and mid-preterm neonates. Before phototherapy, there were signiifcantly correlation of TSB with TcB on forehead, mid sternum and perineum (r=0.813, 0.827, 0.754;P<0.001) and the best correlation was with TcB on mid sternum. The linear regression equation was TSB=1.35TcB-5.50. After phototherapy, there were signiifcantly correlateion of TSB with TcB on forehead, mid sternum, and perineum (r=0.751, 0.807, 0.683;P<0.001) and the best correlation was with TcB on mid sternum. The linear regression equation was TSB=1.01×TcB-0.62. Among three groups, the full-term neonates had the best correlation.ConclusionsAfter phototherapy, the TcB measured on mid sternum which was covered by opaque material is well correlated with TSB. The linear regression model can be established.
