Features of CT and EUS in mesenteric plexiform neurofibroma with Neurofibromatosis type I: A case report.

Plexiform neurofibroma(PNF) is a rare benign tumor of the peripheral nerve, belonging to a subtype of neurofibroma. PNF is common in the head, neck and trunk. It is uncommonly observed in the mesentery.

Prediction of cancer progression in a group of 73 gastric cancer patients by circulating cell-free DNA.

Background: Circulating cell-free DNA (ccf-DNA) in plasma may contain both specific and non-specific of tumor markers. The concentration and integrity of ccf-DNA may be clinical useful for detecting and predicting cancer progression.

Methods: Plasma samples from 40 healthy controls and 73 patients with gastric cancers (two stage 0, 17 stage I, 11 stage II, 33 stage III, and 10 stage IV according to American Joint Committee on Cancer stage) were assessed respectively.

Laparoscopic permanent sigmoid stoma creation through the extraperitoneal route versus transperitoneal route. A meta-analysis of stoma-related complications.

Objectives: To compare laparoscopic extraperitoneal colostomy with transperitoneal colostomy for construction of a permanent stoma by measuring the incidence of parastomal hernia, and other postoperative complications related to colostomy.

Methods: The meta-analysis was carried out in the General Surgery Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China in 2014. A literature search of Medline, EMBASE, Cochrane database, and the Chinese Biomedical Literature Database (CBM) from the years 1990 to 2014 was performed.

[Correlation of single nucleotide polymorphisms of X-ray repair cross complementing group 1 gene to hereditary susceptibility of colorectal cancer].

Objective: To investigate the correlation of single nucleotide polymorphisms (SNP) of XRCC1 gene to hereditary susceptibility of colorectal cancer.

Methods: XRCC1 genotypes in 124 colorectal cancer patients and 214 matched healthy people as control were analyzed by SnaP Shot SNP-typing technique. Five different inheritance models including codominant, dominant, recessive, overdominant and log-additive were analyzed using logistic regression model.

Effects of small interfering RNA inhibit Class I phosphoinositide 3-kinase on human gastric cancer cells.

Aim: To investigate the effects of small interfering RNA (siRNA)-mediated inhibition of Class I phosphoinositide 3-kinase (Class I PI3K) signal transduction on the proliferation, apoptosis, and autophagy of gastric cancer SGC7901 and MGC803 cells.

Methods: We constructed the recombinant replication adenovirus PI3K(I)-RNA interference (RNAi)-green fluorescent protein (GFP) and control adenovirus NC-RNAi-GFP, and infected it into human gastric cancer cells. MTT assay was used to determine the growth rate of the gastric cancer cells.

[Role of carcinoembryonic antigen and cyclooxygenase-2 in the study of molecule incisal edge for colorectal cancer].

Objective: To investigate the expression of cyclooxygenase-2(COX-2) and CEA in the tissues adjacent to the tumor within different distances.

Methods: A total of 42 colorectal cancer tissues were collected.The adjacent tissues within 3 cm to the tumor were procured every 1 cm.
