MicroRNA-328-3p facilitates the progression of gastric cancer via KEAP1/NRF2 axis.

Gastric cancer is a common lethal malignancy and causes great cancer-related mortality worldwide. MicroRNA (miR)-328-3p is implicated in the progression of various human cancers; however, its role and mechanism in the progression of gastric cancer remain unclear.Human gastric cancer cells were incubated with miR-328-3p mimic, inhibitor or the matched negative control.

XPG Asp1104His polymorphism and gastrointestinal cancers risk: a meta-analysis.

Several studies have reported the association between the Asp1104His polymorphism in xeroderma pigmentosum group G (XPG) gene and risk of gastrointestinal cancers. However, the results are inconsistent. This meta-analysis was performed to assess the association between XPG Asp1104His polymorphism and gastrointestinal cancers risk.

[Radiobiological characteristics and MRN complex expression of human nasopharyngeal carcinoma cell lines].

Objective: To study the radiobiological characteristic of human nasopharyngeal carcinoma cell lines CNE1 and CNE2 and the changes in expression MRN (Mre11-Rad50-Nbs1) complex in the cell lines exposed to irradiation.

Methods: CNE1 and CNE2 were irradiated by a linear accelerator. Radiobiological characteristics were detected by colony assay and MTT assay.

The role of prophylactic antibiotics in laparoscopic cholecystectomy in preventing postoperative infection: a meta-analysis.

Background: Although laparoscopic cholecystectomy (LC) is a common and widely applied technique, the use of antibiotics during the perioperative period in infection prevention remains controversial. In our study, a meta-analysis was performed to assess the impact of antibiotic prophylaxis on the postoperative infection rate in LC.

Methods: A literature search was conducted on studies published between January 1966 and March 2010 that involved LC and prophylactic administration of antibiotics.
