Analyses of Genotypes and Phenotypes of Ten Chinese Patients with Wolf-Hirschhorn Syndrome by Multiplex Ligation-dependent Probe Amplification and Array Comparative Genomic Hybridization.

Background: Wolf-Hirschhorn syndrome (WHS) is a contiguous gene syndrome that is typically caused by a deletion of the distal portion of the short arm of chromosome 4. However, there are few reports about the features of Chinese WHS patients. This study aimed to characterize the clinical and molecular cytogenetic features of Chinese WHS patients using the combination of multiplex ligation-dependent probe amplification (MLPA) and array comparative genomic hybridization (array CGH).

Tumor-Suppression Mechanisms of Protein Tyrosine Phosphatase O and Clinical Applications.

Tyrosine phosphorylation plays an important role in regulating human physiological and pathological processes. Functional stabilization of tyrosine phosphorylation largely contributes to the balanced, coordinated regulation of protein tyrosine kinases (PTKs) and protein tyrosine phosphatases (PTPs). Research has revealed PTPs play an important suppressive role in carcinogenesis and progression by reversing oncoprotein functions.

Altered miRNA expression is associated with differentiation, invasion, and metastasis of esophageal squamous cell carcinoma (ESCC) in patients from Huaian, China.

Esophageal squamous cell carcinoma (ESCC) is the leading malignancy in Huaian, China. Recently, emerging studies have suggested that an aberrant microRNA (miRNA) expression signature exists in ESCC. However, there is discordant information available on specific miRNA expression in patients from different regions.

[Factors influencing the bone mineral density in preterm infants].

Objective: To study the bone mineral development and the factors influencing the development in preterm infants.

Methods: Ninety preterm and 90 term infants followed up by the child health care service were randomly enrolled. Tibia quantitative ultrasound measurements were used to evaluate bone mineral density described as supersonic speed of sound (SOS) and Z scores at 6 months old (corrected gestational age for preterm infants).

[Meta analysis of lactic acid bacteria as probiotics for the primary prevention of infantile eczema].

Objective: To determine whether lactic acid bacteria as probiotics is efficacious in the primary prevention of infantile eczema or atopic eczema.

Methods: For this meta analysis of randomized controlled trials (RCT) describing the efficacy of probiotics in infants with eczema or atopic eczema at ages of ≤2 years, a comprehensive search in the databases was performed up to January 2010. Three reviewers independently evaluated the studies for methodological qualities.
