High CpG island methylation of p16 gene and loss of p16 protein expression associate with the development and progression of tetralogy of Fallot.

We examined CpG island methylation in p16 gene and its effect on p16 protein expression in tetralogy of Fallot (ToF) patients to explore its potential implications in the development and progression of ToF. The study subjects consisted of 75 healthy controls and 63 ToF patients recruited at Linyi People's Hospital between January 2012 and June 2014. The 4 mL of peripheral venous blood of each subject was obtained and saved in ethylene diamine tetraacetic acid (EDTA) tubes.

Correlation Between Fractional Exhaled Nitric Oxide Levels and Efficacy of Inhaled Corticosteroids in Children With Bronchial Asthma.

To investigate correlation between fractional exhaled nitric oxide (FeNO) levels and efficacy of inhaled corticosteroids in children with bronchial asthma. Between October 2013 and December 2014, 133 cases of children with bronchial asthma were randomly divided into the glucocorticoid group (n = 67; inhaled with Seretide/Pulmicort) and the nonglucocorticoid group (n = 66; inhaled with short-acting β2 receptor agonist if needed); and alternatively 72 cases of healthy children were regarded as the control group. FeNO, forced expiratory volume in 1 second to predicted value, forced expiratory volume in 1 second/forced vital capacity, induced sputum eosinophils (EOS)%, and total serum immunoglobulin (Ig) E and serum EOS% were detected and childhood asthma control test (C-ACT) scale was investigated pretreatment and 3 and 6 months posttreatment, respectively.

Differential diagnosis of CT images in children with neuroblastomas and ganglioneuroblastomas.

Objective: To investigate the differential features of CT images in children with neuroblastomas (N) and ganglioneuroblastomas (G).

Materials And Methods: Clinical data of 12 children in group G and 15 in group N undergoing CT examination and definitely diagnosed by pathology were retrospectively analyzed. The focal conditions were observed and compared in the two groups, including location, size, boundaries, morphology, enhanced degree and mode, abdominal vascular involvement, presence or absence of spanning the midline, infiltration of peripheral organs, angiography manifestations in tumors or surroundings, presence or absence of calcification and vascular tumor emboli as well as metastases of distal organs and lymph nodes.

Thioredoxin: a novel, independent diagnosis marker in children with autism.

Background: Oxidative stress increases serum thioredoxin (TRX), a redox-regulating protein with antioxidant activity recognized as an oxidative-stress marker. The aim of this study was to assess the clinical significance of serum TRX levels in Autism spectrum disorders (ASD).

Methods: Eighty patients diagnosed with ASD and 100 sex and age matched typically developing children were assessed for serum TRX content at admission.
