MiR-92a antagonized the facilitation effect of extracellular matrix protein 1 in GC metastasis through targeting its 3'UTR region.

MicroRNAs were known to play very important roles in human diseases, and have attracted great interests of research scientists in medicine, toxicology and functional foods. Gastric carcinoma (GC) remains one of the most common and lethal types of malignancy worldwide. However, the molecular mechanism of GC and the role of microRNAs in GC development remain unclear.

Glycemic reduction alters white blood cell counts and inflammatory gene expression in diabetes.

Objective: Systemic inflammation contributes to cardiovascular disease in patients with type 2 diabetes, and elevated white blood cell (WBC) counts are an established risk factor. Our goal is to describe changes in WBCs and inflammatory markers after glycemic reductions in diabetes.

Research Design And Methods: This study enrolled 63 subjects with poorly controlled diabetes, defined as hemoglobin A1c (HbA1c) ≥8% [64 mmol/mol].

Analysis of serum undercarboxylated osteocalcin level in rats with type 2 diabetes mellitus and the correlation with cognitive impairment.

The aim of the study was to investigate the correlation between the serum undercarboxylated osteocalcin (ucOC) level and the blood biochemistry and cognitive impairment in rats with type 2 diabetes mellitus (T2DM). Sprague-Dawley (SD) rats were randomly divided into the normal control group (NC) and type 2 DM group. DM group received the high-fat and high-sugar diet combined with the intraperitoneal injection of low-dose STZ to establish the type 2 DM rat model.

A Risk Factor Analysis of Cognitive Impairment in Elderly Patients with Chronic Diseases in a Chinese Population.

BACKGROUND This study analyzed the risk factors of cognitive impairment (CI) in elderly patients with chronic diseases. MATERIAL AND METHODS In total of 385 elderly patients with chronic diseases were selected and assigned into CI and normal groups. The activities of daily living (ADL), global deterioration scale (GDS), Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), patient-generated subjective global assessment (PG-SGA), and mini nutritional assessment (MNA) were performed to analyze the differences between the 2 groups.

Tumor suppressor genes and their underlying interactions in paclitaxel resistance in cancer therapy.

Objectives: Paclitaxel (PTX) is frequently used in the clinical treatment of solid tumors. But the PTX-resistance is a great obstacle in cancer treatment. Exploration of the mechanisms of drug resistance suggests that tumor suppressor genes (TSGs) play a key role in the response of chemotherapeutic drugs.

Cardiomyocyte-specific loss of diacylglycerol acyltransferase 1 (DGAT1) reproduces the abnormalities in lipids found in severe heart failure.

Diacylglycerol acyltransferase 1 (DGAT1) catalyzes the final step in triglyceride synthesis, the conversion of diacylglycerol (DAG) to triglyceride. Dgat1(-/-) mice exhibit a number of beneficial metabolic effects including reduced obesity and improved insulin sensitivity and no known cardiac dysfunction. In contrast, failing human hearts have severely reduced DGAT1 expression associated with accumulation of DAGs and ceramides.

Prognostic role of human epidermal growth factor receptor in gastric cancer: a systematic review and meta-analysis.

Background And Aims: Human epidermal growth factor receptor (EGFR) and HER2 (ErbB2) both belong to EGFR family, which are overexpressed in a significant proportion of cases of gastric cancer (GC). Various studies have evaluated the prognostic value of EGFR or HER level in GC. However, the overall test performance remains unclear.

Effects of phlorizin on diabetic retinopathy according to isobaric tags for relative and absolute quantification-based proteomics in db/db mice.

Purpose: Diabetic retinopathy (DR) is a leading cause of vision loss in working-age people. To retard the development and progression of retina lesions, effective therapeutic strategies directed toward key molecular targets are desired. Phlorizin is effective in treating diabetic complications, but little is known about functional protein changes that may mediate its actions.

Promoter methylation of p16, Runx3, DAPK and CHFR genes is frequent in gastric carcinoma.

Aims And Background: Transcriptional silencing induced by hypermethylation of CpG islands in the promoter regions of genes is believed to be an important mechanism of carcinogenesis in human cancers including gastric cancer. A number of reports on methylation of various genes in gastric cancer have been published, but most of these studies focused on cancer tissues or only a single gene. In this study, we determined the promoter hypermethylation status and mRNA expression of 4 genes: p16, Runx3, DAPK and CHFR.

[Effects of low-dose aspirin on primary prevention of cardiovascular events: a systematic review].

Objective: To evaluate the effect and safety of low-dose aspirin for primary prevention of cardiovascular events.

Methods: We searched for randomized controlled trials (RCT) in the following electronic databases: MEDLINE, EMbase, the Cochrane Library (Issue 3, 2008), CBM, CNKI. Quality assessment and data extraction were conducted by two reviewers independently.

[Effects of aging and decreased glomerular filtration rate on the prevalence of anemia in elderly population receiving body check from urban area of Hefei, China.].

Objective: To investigate the effects of aging and the decreased glomerular filtration rate on the prevalence of anemia in elder receiving body check from urban area of Hefei, China.

Methods: A total of 4547 > 60 years subjects received healthy examination in Healthy Center of Anhui Provincial Hospital from January 2005 to December 2007 were enrolled in this study. Anemia was defined as hemoglobin < 120 g/L in men or < 110 g/L in women.

Pathobiologic implications of methylation and expression status of Runx3 and CHFR genes in gastric cancer.

Runx3 and CHFR genes were defined as tumor suppressor genes in gastric cancer (GC) recently. This paper was to investigate the roles of methylation and expression status of Runx3 and CHFR genes in GC patients. Methylation-specific polymerase chain reaction (MSP) and bisulfite DNA sequencing (BSP) were used to detect methylation status of Runx3 and CHFR genes in GC patients.

Promoter methylation of CHFR gene in gastric carcinoma tissues detected using two methods.

Background And Objective: Transcriptional silencing induced by CpG island methylation is believed to be one of the important mechanisms of carcinogenesis. Checkpoint with fork head-associated and ring finger (CHFR) governs the transition from prophase to prometaphase in response to mitotic stress. This study was to analyze the relationship between the methylation of CHFR gene and the clinicopathologic features of gastric cancer, and the difference of results between methylation-specific polymerase chain reaction (MSP) and combined bisulfite restriction analysis (COBRA) in detecting aberrant methylation of CHFR gene in gastric cancer.

[Chiral selectivity in differentiation of lung cancer A549 cell to vascular endothelial cells after drug resistance induced by D-or L-methotrexate enantiomers].

Objective: To study the chiral selectivity in vascular endothelial differentiation in drug resistant lung cancer cells induced by high-dose L- or D-methotrexate (MTX) enantiomer.

Methods: Human lung cancer cells of the line A549 were co-cultured with high-dose (15 micromol/L) L- or D-MTX enantiomer so as to develop cancer cells resistant to MTX. MTT method was used to detect the drug resistant index.

High-performance capillary electrophoretic method for the quantification of global DNA methylation: application to methotrexate-resistant cells.

Global DNA hypomethylation in tumor tissue is a common characteristic in a variety of malignancies such as breast, colon, oral, lung, and blood cancers. A rapid and sensitive method has been developed for the determination of global DNA methylation in cells. Five substances--2'-deoxycytidine (dC), 5-methyl 2'-deoxycytidine (mdC), 2'-deoxyadenosine (dA), 2'-deoxythymidine (dT), and 2'-deoxyguanosine (dG)--were completely separated by high-performance capillary electrophoresis in 10 min.

Objective: To investigate the effect of amino acid parenteral nutritional (PN) support on serum tryptophan and melatonin in non-small cell lung cancer (NSCLC) patients receiving chemotherapy.

Methods: Seventy-two patients with inoperable NSCLC were divided into three groups randomly: control group, 250 ml/d amino acids PN therapy group and 500 ml/d amino acids PN therapy group. The same NP (cisplatin + vinorelbine) chemotherapy was carried out in all the three groups.
