Newborn Screening for 6 Lysosomal Storage Disorders in China.

Importance: Newborn screening (NBS) for lysosomal storage disorders (LSDs) is becoming an increasing concern in public health. However, the birth prevalence of these disorders is rarely reported in the Chinese population, and subclinical forms of diseases among patients identified by NBS have not been evaluated.

Objective: To evaluate the birth prevalence of the 6 LSDs in the Shanghai population and determine subclinical forms based on clinical, biochemical, and genetic characteristics.

Contribution of and the HLA Genes to Biliary Atresia Risk in Chinese.

Nonsyndromic biliary atresia (BA) is a rare polygenic disease, with autoimmunity, virus infection and inflammation thought to play roles in its pathogenesis. We conducted a genome-wide association study in 336 nonsyndromic BA infants and 8900 controls. Our results validated the association of rs17095355 in with BA risk (odds ratio (OR) = 1.

Association analysis and functional follow-up identified common variants of accounting for risk to biliary atresia.

Biliary atresia (BA) is a destructive, obliterative cholangiopathy characterized by progressive fibro-inflammatory disorder and obliteration of intra- and extrahepatic bile ducts. The () gene mutations have been found in some isolated BA cases. We aim to explore the association of common variants in with isolated BA risk in the Chinese Han population.

Association Analysis of Variants of and With Hirschsprung Disease Susceptibility in Han Chinese and Functional Evaluation in Zebrafish.

Hirschsprung disease (HSCR) has a higher incidence in children with Down syndrome (DS), which makes trisomy 21 a predisposing factor to HSCR. and are close together on the HSCR-associated critical region of chromosome 21. Common variants of and rare variants of were implicated to be associated with sporadic HSCR.

Bile salt-dependent lipase promotes the barrier integrity of Caco-2 cells by activating Wnt/β-catenin signaling via LRP6 receptor.

Bile salt-dependent lipase (BSDL) within intestinal lumen can be endocytosed by enterocytes and support the intestinal barrier function. However, the epithelial-supporting effect of this protein has not been verified in a human cell line and neither the direct signaling pathway nor the function of endocytosis in this process has been clearly identified. We sought to investigate the signaling pathway and the membrane receptor through which BSDL might exert these effects using intestinal epithelial cells.

Association of Variants in , 3p24.1, and 10q11.21 Regions With Hirschsprung's Disease in Han Chinese Population.

Hirschsprung's disease (HSCR) is a rare genetically heterogeneous congenital disorder. A recent study based on whole genome sequencing demonstrated that common variants at four novel loci, which contained two intronic variants on and , and intergenic variants located between and at 3p24.1, and between and at 10q11.

Common variants of NRG1 and ITGB4 confer risk of Hirschsprung disease in Han Chinese population.

Background: Hirschsprung disease (HSCR) is a neurodevelopmental disorder with a strong genetic component. Common variants of NRG1 contributed to HSCR risk in Asians, and rare variants of ERBB2 and ITGB4 were found to be associated with HSCR. ERBB2 and ITGB4 are partners of Nrg1/ErbB pathway, which is important in HSCR pathogenesis.

Common variation of the NSD1 gene is associated with susceptibility to Hirschsprung's disease in Chinese Han population.

Background: Hirschsprung's disease (HSCR) is the most common congenital cause of intestinal obstruction in children. Sotos syndrome (SoS) is an overgrowth disorder with constipation and sometimes accompanied by HSCR. NSD1 gene mutation is the main cause of SoS.

Association of common variation in and with biliary atresia susceptibility.

Biliary atresia (BA) is an idiopathic neonatal cholestatic disease. Recent genome-wide association study (GWAS) revealed that common variation of , , , and gene was associated with BA susceptibility. We aimed to evaluate the association of these genes with BA in Chinese population.

Bile salt dependent lipase promotes intestinal adaptation in rats with massive small bowel resection.

Intestinal adaptation is important for the short bowel syndrome (SBS) patients. Growing evidence has suggested that bile salt dependent lipase (BSDL) not only has the lipolytic activity, but also the immune-modulating and pro-proliferative activities. The purpose of the present study was to investigate the effects of BSDL on intestinal adaptive growth and gut barrier function in a rat model of SBS.

Real Time Monitoring of Inhibition of Adipogenesis and Angiogenesis by (-)-Epigallocatechin-3-Gallate in 3T3-L1 Adipocytes and Human Umbilical Vein Endothelial Cells.

Little is known about the effect of (-)-epigallocatechin-3-gallate (EGCG) on angiogenesis in adipocytes. We aimed to test the effect of EGCG on the expression of vascular endothelial growth factor (VEGF) in adipocytes. The levels of VEGF secretion, the expression of VEGF message ribonucleic acid (mRNA) and VEGF protein in 3T3-L1 cells were measured by enzyme linked immunosorbent assay (ELISA), real time polymerase chain reaction (PCR), and immunofluorescence staining, respectively.

Molecular diversity and hypoglycemic polypeptide-P content of Momordica charantia in different accessions and different seasons.

Background: Momordica charantia (MC) has been used for treating diabetes mellitus from ancient times in Asia, Africa and South America. There are many MC accessions in local markets. Polypeptide-P as a main hypoglycemic component in MC was first studied in this experiment to illustrate the different contents in MC of different accessions and different harvesting times.

Human β-defensin-3 promotes intestinal epithelial cell migration and reduces the development of necrotizing enterocolitis in a neonatal rat model.

Background: The aim of this study was to investigate the effects of human β-defensin-3 (hBD3) on intestinal wound healing and in a neonatal rat model of necrotizing enterocolitis (NEC).

Methods: Enterocyte migration and proliferation were detected in vitro and in vivo. The role of chemokine receptor CCR6 and its downstream signaling pathway was assessed.

Protective effects of hydrogen-rich saline on necrotizing enterocolitis in neonatal rats.

Purpose: The aim of this study was to test the hypothesis that hydrogen-rich saline (HRS) might have protective effects on the development of necrotizing enterocolitis (NEC) in a neonatal rat model.

Methods: NEC was induced in male newborn Sprague-Dawley rats by formula feeding, exposure to asphyxia and cold stress. Sixty-four rat pups were divided randomly into four groups: C+NS (n=11), C+H2 (n=11), NEC+NS (n=20), and NEC+H2 (n=22).
