Ce-doped gadolinium gallium aluminum oxide (Ce: GGAG) precursors were first prepared by the microwave-assisted homogeneous precipitation method (MAHP). Thermal gravity-differential thermal analysis (TG-DTA), X-ray diffraction (XRD), specific surface area analysis (BET) and field emission scanning electron microscopy (FE-SEM) were employed to investigate the crystal structure, phase evolution and morphologies of the Ce: GGAG precursors and powders. The influence of Ga ion concentration in the salt solution on the properties of Ce: GGAG powders was investigated.

This work aimed to identify potential hub genes and dysregulated pathways in the CRC by bioinformatics analysis. Three gene expression datasets were collected from GEO datasets, including tumor sample ( = 242) and adjacent nontumor tissue sample ( = 59).

Numerous studies have shown that CMTM family members have a variety of important roles in the occurrence and progression of cancer. CMTM7 has also been reported to be down-regulated in some digestive system tumors, but the expression patterns and pathological role of CMTM7 in gastric cancer remains unclear. In this study, we found that both CMTM7 and SOX10 were significantly down-regulated in gastric cancer tissues compared with paracancerous tissues, and the expression pattern of CMTM7 and SOX10 were strongly correlated (r = 0.

However, the expression and biological role of miR-370 in colon cancer remains undefined. In the present study, miR-370 expression in both normal and malignant colon tissues was quantified by quantitative polymerase chain reaction.

Background And Objective: X-ray repair cross-complementing group 3 (XRCC3) is responsible for maintaining the integrity of the genome, playing a critical role in protecting it against mutations which lead to cancer. Polymorphisms at exons 7 of the XRCC3 gene may alter the XRCC3 repair efficiency. The aim of this study is to derive a precise estimation of the relationship between XRCC3 Thr241Met polymorphism and gastric cancer (GC) risk.

Objective: To evaluate safety and efficacy of preoperative administration of enteral nutrition support in gastric cancer patients at risk of malnutrition.
Methods: A single center randomized controlled clinical trial was performed in 60 gastric cancer patients in West China Hospital from May to October 2012. Thirty patients were given enteral nutrition support(Ensure(R)) manufactured by Abbott Laboratories for ten consecutive days before surgical operation in the treatment group, and 30 patients were given an isocaloric and isonitrogenous homogenized diet in the control group for 10 days as well.

Aim: To assess the theoretical advantages of magnetic endoscope imaging (MEI) over standard colonoscopies (SCs) and to compare their efficacies.
Methods: Electronic databases, including PubMed, EMBASE, the Cochrane library and the Science Citation Index, were searched to retrieve relevant trials. In addition, abstracts from papers presented at professional meetings and the reference lists of retrieved articles were reviewed to identify additional studies.
Background And Aims: Supplementation of fish oil (FO) containing lipid emulsions has been associated with a reduction in the length of hospital stay, infections and liver dysfunction in patients undergoing major surgery. We carried out a meta-analysis and subgroup analysis to examine randomised clinical trial (RCT)-based evidence of the aforementioned effects.
Methods: Four databases, reference lists and the WHO ICTRP were systematically searched for RCTs to access the clinical efficacy of fish oil-enriched total parenteral nutrition in post-surgery patients.

Background And Objective: The association between glutathione S-transferase T1 (GSTT1) gene polymorphisms and colorectal cancer (CRC) susceptibility is still controversial. In order to clarify the effect of GSTT1 genotype on the CRC risk, we carried out an updated meta-analysis of published case-control studies to provide more precise evidence.
Methods: Two investigators independently searched the databases of Pubmed, EMBASE and China National Knowledge Infrastructure (CNKI) up to October 15, 2012.
