Questions remain about the relationship between type 2 diabetes mellitus (type 2 DM) and the risk of hepatocellular carcinoma (HCC), especially in patients with chronic liver diseases. We carried out a meta-analysis of cohort studies to explore these issues. We searched PubMed and EMBASE for studies on the association between type 2 DM and the risk of HCC(More)
The aim of this study was to investigate the clinicopathological characteristics of colorectal serrated lesions associated with invasive carcinoma and high-grade intraepithelial neoplasm (HIN), as well as to determine the immunohistochemical expression of MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), K-ras and O6-methylguanine-DNA methyltransferase (MGMT).(More)
Glioma is an aggressive tumor with poor prognosis. Identification of precise prognostic marker and effective therapeutic target is important in the treatment of glioma. HTATIP2 is a novel tumor suppressor gene, which is frequently silenced by epigenetic mechanisms in many caners. However, the expression of HTATIP2 and how it is regulated in glioma are(More)
OBJECTIVE To investigate methylation status of Wif-1 and β-catenin expression in colorectal serrated lesions. METHODS Various colorectal lesions were collected including 52 cases of hyperplastic polyps, 41 cases of sessile serrated adenoma, 23 cases of traditional serrated adenoma, 24 cases of colorectal cancer and 24 cases of normal mucosa. All specimens(More)
OBJECTIVE To detect the consistency of the c-MET gene amplification in peripheral blood and tumor tissue of patients with non-small cell lung cancer (NSCLC) and discuss the clinical application value of c-MET gene amplification in peripheral blood. MATERIALS AND METHODS Real-time fluorescent quantitative polymerase chain reaction was used to test the(More)
BACKGROUND To explore the diagnostic values of CD117 and PDGFRA protein expressions, used alone or in combination with DOG1 protein, for gastrointestinal stromal tumors (GIST). METHODS The CD117, PDGFRA and DOG1 protein expressions in 99 GIST specimens and 25 non-GIST specimens were retrospectively determined, and the potential correlations were analyzed.(More)
OBJECTIVE To study the clinicopathologic characteristics, immunophenotypes, pathologic diagnosis and differential diagnosis of gastrointestinal inflammatory fibroid polyp (IFP). METHODS The clinical data, histologic features and immunohistochemical results of 6 cases of gastrointestinal inflammatory fibroid polyp were analyzed, with review of literature.(More)
Primary thyroid lymphomas are rare, and the majority are B-cell lymphoma. Primary Burkitt's lymphoma (BL) of the thyroid is much less common than the other types of lymphoma. The current study presents the case of an eight-year-old male with a mass in the right lobe of the thyroid, which was detected by B-ultrasound. The patient was diagnosed with BL by(More)
Burkitt lymphoma (BL) is a highly aggressive neoplasm, which arising from the germinal center or post germinal center B-cell. Primary breast lymphomas are extremely rare, and the most common histologic type is diffuse large B-cell lymphoma. Primary BL of the breast is much less common than the other types of lymphoma. Here, we report an extremely rare case(More)
