AIMS: Most dilated cardiomyopathies are either an ischemic dilated cardiomyopathy (IsDC) or an idiopathic dilated cardiomyopathy (IdDC). The treatments for both IsDC and IdDC are of a similar nature (upwards of 90%). Coronary revascularization, however, is only feasible for IsDC. The purpose of this study was to determine if microRNAs (miRNAs) could be used as biomarkers to distinguish between IsDC and IdDC. MATERIALS AND METHODS: Patients were divided into two groups: IsDC and IdDC, with 25 patients in each group, and 10 healthy persons serving as a control group...

BACKGROUND: The uncoupling protein 2 (UCP2) gene plays an important role in the complications of type 2 diabetes (T2D). However, the association between variants in the UCP2 gene and diabetic retinopathy (DR) in Han Chinese T2D patients remains unclear. METHODS: Two single-nucleotide polymorphisms (SNPs) [rs659366 (-866G/A) and a 45-bp insertion/deletion (I/D) in the 3'-UTR] in the UCP2 gene were genotyped in a study cohort of 209 T2D patients with DR and 199 T2D patients without DR by direct DNA sequencing...

Rong Jing, Yunlei Liu, Peng Guo, Tong Ni, Xiang Gao, Rong Mei, Xijing He, Jianlin Zhang
OBJECTIVE: Lumbar disc herniation (LDH) is a common and frequent orthopedic disease with strong genetic determinants. The disruption of the intervertebral disc extracellular matrix has been found to play a key role in the development of LDH, suggesting that abnormal matrix metalloproteinases (MMPs) may promote the degradation of the disc matrix. MMP-9, an important member of the MMP family, is a good candidate for the LDH susceptibility gene. The present study aimed to investigate the association of common variants in the MMP-9 gene with the risk, severity, and clinical characteristic variables of LDH...
