RESUMO
Objective To investigate the applications of total maturation scores (TMS) in assessment of the hypoxic ischemic encephalopathy (HIE) group and matched group with MRI and to find which patterns of HIE can delay the brain maturation in neonate.Methods MRI were performed on 43 full term neonates (28 HIE newborns and 15 matched controls) who were further divided into three groups,including 37-39 weeks postmenstrualage (PMA) (13 cases),39-41 weeks PMA (16 cases),and 41-44 weeks PMA (14 cases).MRI features and TMS scores were evaluated simulataneously.Results TMS gradually increased with PMA at each stage.While TMS,cortical folding and germinal matrix were all higher in matched group (P＜0.05),myelination and glial cell migration item were lower in HIE group (P＞0.05).Conclusion TMS can reflect brain development in the full term neonates.HIE may delay the brain maturation due to injury of the cortical myelin and neurons.TMS can evaluate the neonatal brain development and injury easily,quantitatively and effectively.
RESUMO
Objective To detect the correlations of miR -106 a expression with clinical features of pa-tients with colon cancer ,and to explore the significance of miR -106 a as a prognostic factor .Methods One hun-dred and five patients with primary colon cancer were retrospectively enrolled in this study including their clinical information and slices of FFPE.miR-106a expression was detected by qRT -PCR,and analyzed the correlation between the level of miR -106a and clinical features and survival .Results The level of miR -106a in tumor tissue was higher than adjacent normal tissue (1.142 vs.0.685,P<0.001).miR-106a was correlated with TNM stage and lymphnode metastasis .The higher miR -106a expression,the poorer survival patients were .The hazard risk was increased 3.390 folds(95%CI for HR:1.028 ~11.178)when compared high expression group with the low.Conclusion The aberrant expression of miR -106a may be associated with colon cancer .It will po-tentially be a therapeutic target and prognostic factors .
