Circulating microRNA expression profiles may be promising biomarkers for diagnosis and assessment of the prognosis of cancer patients. Quantitative polymerase chain reaction (qPCR) is a sensitive technique for estimating expression levels of circulating microRNAs. However, there is no current consensus on the reference genes for qPCR analysis of circulating(More)
In patients with gastric cancer (GC), circulating microRNA-21 (miR-21) is overexpressed and may serve as a diagnostic biomarker. In the present study, it was hypothesized that the serum miR-21 expression levels were associated with prognosis in the patients with GC. The expression levels of serum miR-21 were measured using quantitative polymerase chain(More)
Gastric cancer (GC) is the one of the most common types of cancer in Asia. To better understand the molecular mechanisms underlying GC, and to seek new markers of tumor progression, we used a proteomics strategy to analyze the protein expression patterns in matched pairs of GC tissue and normal gastric mucosa of 8 GC patients. Comparative proteomic(More)
The CCN family of proteins comprises the members CCN1, CCN2, CCN3, CCN4, CCN5 and CCN6. They share four evolutionarily conserved functional domains, and usually interact with various cytokines to elicit different biological functions including cell proliferation, adhesion, invasion, migration, embryonic development, angiogenesis, wound healing, fibrosis and(More)
BACKGROUND The primary objective of this multicenter post-market study was to compare the cosmetic outcome of triclosan-coated VICRYL Plus sutures with Chinese silk sutures for skin closure of modified radical mastectomy. A secondary objective was to assess the incidence of surgical site infection (SSI). METHODS Patients undergoing modified radical(More)
OBJECTIVES The aim of this study was to determine the etiology tendency of acute pancreatitis (AP) in the Beijing region and the relationship with influencing factors. METHODS This retrospective multicenter study enrolled 8 representative general hospitals from January 1, 2006 to December 31, 2010. The etiology tendency was analyzed, and the relationship(More)
The tumor suppressor gene P53 plays an important role in carcinogenesis, and the P53 pathway is central both in reducing cancer frequency and in mediating the response of cancer therapies. MDM2, MDM4 and Hausp genes are all critical regulators of the tumor suppressor P53. Many studies have evaluated the association of single nucleotide polymorphisms (SNPs)(More)
BACKGROUND Hepatocellular carcinoma (HCC) is prevalent worldwide and early diagnosis of HCC is critical for effective treatment and optimal prognosis. METHODS Serum was screened first by immunoproteomic analysis for HCC-related tumor associated antigens (TAAs). Selected TAAs were clinically evaluated retrospectively in patients with HCC, liver cirrhosis,(More)
PURPOSE Luminal subtype breast cancer is defined as oestrogen receptor (ER)- and/or progesterone receptor (PR)- positive breast cancer. We detected the expression of ER-α, ER-Β1 and ER-Β2 in the tissue samples of invasive luminal subtype breast cancer patients, evaluated the correlations between these ER statuses and prognosis, and tried to clarify whether(More)
