Short rib‑polydactyly syndrome type III (SRPS3) is a lethal perinatal skeletal disorder consisting of polydactyly and multi‑system organ abnormalities. To further assess the pathogenicity of two pairs of compound heterozygotes and to search for novel molecular etiology, X‑rays and hematoxylin and eosin staining were conducted in three cases: Two retrospective samples and a newly identified patient with SRPS3. In addition, next‑generation sequencing was used to evaluate a fetus with SRPS3.

Background: DNA methylation is a molecular modification of DNA that is vital and occurs in gene expression. In cancer tissues, the 5'-C-phosphate-G-3'(CpG) rich regions are abnormally hypermethylated or hypomethylated. Therefore, it is useful to find out the diseased CpG sites by employing specific methods.

However, there are few studies on the abnormal regulation of TBX1 gene expression. The purpose of this work was to investigate the role of miR-144 and TBX1 in cardiac development by studying the regulatory relationship and mechanism of miR-144 on TBX1/JAK2/STAT1 in cardiomyocytes.

Most SRS cases are caused by hypomethylation of the paternal imprinting center 1 (IC1) in chromosome 11p15.5 and maternal uniparental disomy in chromosome 7 (UPD7).

Moreover, a diet high in iTFAs could increase the risk of obesity, cardiovascular diseases (CVDs) and type 2 diabetes mellitus. Glucose and lipid metabolism are closely linked in white adipose tissue (WAT), yet the underlying mechanisms of the effect of iTFAs in WAT are poorly understood.

One limitation of the existing methods for survival analysis is that these ignore the regulatory networks and pathways information. To merge prior pathway information into the analysis of genomic data, we proposed a network-based regularization method for the L penalty and applied it to high-dimensional survival analysis data.

We compared the biomechanical stability imparted to the C-2 vertebrae by four designed posterior screw and rod fixation techniques for the management of odontoid fractures. A three-dimensional finite element model of the odontoid fracture was established by subtracting several unit structures from the normal model from a healthy male volunteer.

The present study was undertaken to study the effects of exogenous H2S on ischemia/reperfusion (I/R) injury of spinal cord and the underlying mechanisms.
Methods: The effects of exogenous H2S on I/R injury were examined by using assessment of hind motor function, spinal cord infarct zone by Triphenyltetrazolium chloride (TTC) staining.
Background: The Cardiac α actin 1 gene (ACTC1) has been related to familial atrial septal defects. This study was set to explore a potential role of this gene in the formation of sporadic congenital heart disease (CHD).
Methods And Results: Assessment of cardiac tissue samples from 33 patients with sporadic CHD (gestational age (GA) 18 weeks-49 months) with real-time RT-PCR, Western blotting and immunohistochemistry has revealed a markedly decreased ACTC1 expression in the majority of samples (78.

Objective: To examine serum concentration of interleukin-18 (IL-18) and IL-18 mRNA expression in peripheral blood mononuclear cells (PBMCs) in children with primary nephrotic syndrome (PNS) and explore the possible role of IL-18 in steroid-resistant nephrotic syndrome (SRNS).
Methods: Sixty-six children with newly diagnosed PNS, including 39 cases of steroid sensitive nephrotic syndrome (SSNS) and 27 cases of SRNS, were enrolled. Forty healthy children were used as a normal control group.
Response of water quality to agricultural cultivation was investigated for the Liangwanghe River catchment of Fuxianhu Lake region in Yunnan Province of China. Two typical tillage lands-the rice-wheat rotation (R-W) and the tobacco-pea (T-P) rotation were selected and monitored. Groundwater quality and water quality of Liangwanghe River were monitored simultaneously, as well as the farmland cultivation situation at that time.

Objective: To study serum concentration and mRNA expression of interleukin-13 (IL-13) in children with steroid-responsive nephrotic syndrome (SRNS) and the effect of methylprednisolone pulse therapy (MPT) on IL-13 expression.
Methods: Twenty-eight children with SRNS were enrolled in this study. Serum protein level of IL-13 was measured using ELISA and IL-13 mRNA expression in peripheral blood mononuclear cells (PBMC) was detected with RT-PCR before MPT, 2 and 5 days after MPT, and 2 weeks after disappearance of proteinuria following MPT.
Objective Tissue inhibitor of metalloproteinase-1 (TIMP-1) is a multifunctional protein that has thc capacity to modify cellular activities and to modulate matrix turnover. This paper revealed the contributive role of TIMP-1 in progressive muscular dystrophy (PMD). Methods We examined the expression and cellular localization of TIMP-1 protein using biopsied frozen muscle from patients with Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), congenital muscular dystrophy (CMD) by immunohistochemistry, double immunofluorescence and Western blot analysis.

Objective: Progressive muscular dystrophy (PMD) is characterized by muscle fiber necrosis, regeneration, and endomysial fibrosis. Although absence of dystrophin and subsarcolemmic protein has been known as the cause of muscle fiber degeneration, pathogenesis of interstitial fibrosis is still unknown. The aim of this study was to investigate the role of connective tissue growth factor (CTGF) in PMD and its relationship with muscular fibrosis.
