Awareness of knowledge and practice regarding physical activity: A population-based prospective, observational study among students in Nanjing, China.

Background: Physical activity (PA) promotion has proven effectiveness in preventing childhood obesity. Increasing children's health knowledge is the most frequently used approach in PA intervention programs targeting childhood obesity prevention. However, little is known about the specific association between the change in a child's knowledge awareness and their PA practice.

Multiple Magnetic Foreign Bodies Causing Severe Digestive Tract Injuries in a Child.

Foreign body (FB) ingestion is a common emergency as well as a major cause of accidental injury and represents a severe public health problem in childhood, especially in infants. Most cases of FB ingestion reported in children aged between 6 months and 3 years depend primarily on the fact that young children are more likely to explore objects using their mouth and are not able to distinguish edible objects from nonedible ones, their teeth are physiologically lacking, and they have poor swallowing coordination. Although, sometimes it can cause serious complications, FB ingestion generally has a low mortality rate.

NIDO, AMOP and vWD domains of MUC4 play synergic role in MUC4 mediated signaling.

MUC4 mucin is well known as an important potential target to overcome pancreatic cancer. Three unique domains (NIDO, AMOP, and vWD) with unclear roles only present in MUC4 but are not found in other membrane-bound mucins. Our previous studies first reported that its splice variant, MUC4/Y can be a model of MUC4 (MUC4 gene fragment is more than 30KB, too huge to clone and eukaryotic express) in pancreatic cancer.

Treatment of Unilateral Lambdoid Synostosis Using Cranium Distraction Osteogenesis With Z-shaped Osteotomy.

Purpose: We studied the effect of cranium distraction osteogenesis using Z-shaped osteotomy to treat unilateral lambdoid synostosis.

Methods: Simulating the occipital, parietal, and temporal bones as a hemisphere, we designed a lambdoid suture that connected parallel osteotomy and sagittal sutures or extended to fossa cranii posterioras much like the parallel lines connect the upper and lower aspects of the letter Z. Two to 3 distraction devices were then installed after the Z-shaped osteotomy suture.

Apoptotic neuron-secreted HN12 inhibits cell apoptosis in Hirschsprung's disease.

Perturbation in apoptosis can lead to Hirschsprung's disease (HSCR), which is a genetic disorder of neural crest development. It is believed that long noncoding RNAs (lncRNAs) play a role in the progression of HSCR. This study shows that apoptotic neurons can suppress apoptosis of nonapoptotic cells by secreting exosomes that contain high levels of HN12 lncRNA.

Internal Distraction Osteogenesis With Piezosurgery Oblique Osteotomy of Supraorbital Margin of Frontal Bone for the Treatment of Unilateral Coronal Synostosis.

Purpose: To assess the utility of internal distraction osteogenesis with Piezosurgery oblique osteotomy of supraorbital margin of frontal bone for the treatment of unilateral coronal synostosis and to study the outcome and complications of this procedure. Oblique osteotomy allows for entry into the cranial cavity, and along with parallel cut to the roof of the orbit, avoids the need to cut into the orbit which forms the frontal flap.

Methods: Oblique osteotomy was performed along the supraorbital rim to do a frontal suture of the glabella (ages of patients were less than 1 year) or on the opposite side of the supraorbital rim (ages of patients were older than 1 year) after performing a suturectomy of the effected coronal suture.

Genetic Screening and Analysis of LKB1 Gene in Chinese Patients with Peutz-Jeghers Syndrome.

BACKGROUND Peutz-Jeghers syndrome (PJS) is an autosomal dominant genetic disease. It severely decreases patient quality of life and leads elevated cancer risk. Germline mutation of LKB1 is the leading cause of familial PJS.

Insights from lncRNAs Profiling of MIN6 Beta Cells Undergoing Inflammation.

Type 1 diabetes mellitus (T1DM) is an organ-specific autoimmune disease characterized by chronic and progressive apoptotic destruction of pancreatic beta cells. During the initial phases of T1DM, cytokines and other inflammatory mediators released by immune cells progressively infiltrate islet cells, induce alterations in gene expression, provoke functional impairment, and ultimately lead to apoptosis. Long noncoding RNAs (lncRNAs) are a new important class of pervasive genes that have a variety of biological functions and play key roles in many diseases.

[Experience in children airway foreign bodies: an analysis of 220 cases].

To observe the clinical characteristics, pathogen infection and the diagnostic reliability of CT multiplanar reconstruction(CT MPR) in the children with airway foreign bodies.We retrospectively reviewed 220 pediatric patients suspected with respiratory foreign bodies who were simultaneously examined by CT MPR, bronchoscopy and secretion culture.Then we summarized their characteristics from treatment process, age distribution, foreign body kinds, examination results of CT MPR, bronchoscopy and secretion culture.

Tumor-associated macrophages promote invasion via Toll-like receptors signaling in patients with ovarian cancer.

Tumor-associated macrophages (TAMs) derived from peripheral blood monocytes recruit into tumor microenvironment and display functions associated with tumor progression. The mechanisms by which TAMs display roles that associated with the invasion ability of ovarian cancer have not been well investigated. In our research, we found abundant TAMs infiltrate in ovarian cancer compared with benign ovarian tumor tissues.

Negative feedback circuitry between MIR143HG and RBM24 in Hirschsprung disease.

Hirschsprung disease (HSCR) is a genetic disorder of neural crest development. It is also believed that epigenetic changes plays a role in the progression of this disease. Here we show that the MIR143 host gene (MIR143HG), the precursor of miR-143 and miR-145, decreased cell proliferation and migration and forms a negative feedback loop with RBM24 in HSCR.

BDE47 induces rat CYP3A1 by targeting the transcriptional regulation of miR-23b.

Cytochrome P450 3A (CYP3A) is the most abundant CYP450 enzyme in the liver and is involved in the metabolism of over 50% of xenobiotics. Our previous studies revealed that 2,2',4,4'-tetrabromodiphenyl ether (BDE47) could induce rat CYP3A1 expression, but the molecular basis remains unclear. Using in silico analysis, we identified a potential miR-23b recognition element (MRE23b) in the 3'-UTR region of CYP3A1 mRNA, which was verified by the luciferase assay.
