Association between rs735482 polymorphism and risk of cancer: A meta-analysis of 10 case-control studies.

Several studies have inspected the relationship between rs735482 polymorphism and the risk of some human cancers, but the findings remain controversial. We designed this meta-analysis to validate the association between rs735482 polymorphism and cancer risk. All articles were published before September 1, 2018 and searched in Pubmed, Embase, Web of Science, China National Knowledge Infrastructure, WangFang, and Chinese BioMedical databases, STATA 12.

Prognostic significance of excision repair cross complementation group 1 rs2298881 in patients with gastric cancer receiving platinum-based chemotherapy: A PRISMA-compliant meta-analysis.

Background: Gastric cancer (GC) is a strong cause of global cancer mortality. Nucleotide excision repair (NER) can modulate platinum-based chemotherapeutic efficacy by removing drug-produced DNA damage. Some studies have found a link between excision repair cross complementation group 1 (ERCC1) rs2298881, one gene in NER pathway, and response to chemotherapy.

Probing depth reduction of laser application in periodontal therapy: a network meta-analysis.

The aim was to systematically evaluate the probing depth (PD) reduction of lasers in scaling and root planing (SRP) of chronic periodontitis by network meta-analysis (NMA). Randomized controlled clinical trials (RCTs) were searched through electronic-search and hand-search up to January 2020. Standard mean different (SMD) and 95% confidence interval (CI) were counted for PD reduction.

Clinical effectiveness of Er,Cr:YSGG lasers in non-surgical treatment of chronic periodontitis: a meta-analysis of randomized controlled trials.

The meta-analysis aimed to systematically evaluate all the available pieces of evidence concerning the clinical effectiveness of Er,Cr:YSGG lasers (erbium, chromium, yttrium scandium gallium garnet laser) in the non-surgical treatment of patients with chronic periodontitis, and provide guidance for clinicians about the application of Er,Cr:YSGG lasers during the process of non-surgical periodontal treatments. The meta-analysis was conducted with data extracted from 16 randomized controlled clinical trials (RCTs) that compare Er,Cr:YSGG lasers adjunct/substitute to scaling and root planing (SRP) with SRP alone for the treatment of chronic periodontitis published in English or Chinese from January 2000 to January 2020. The weighted mean differences (WMDs) and 95% confidence intervals (CIs) were counted for probing depth (PD) reduction, clinical attachment level (CAL) gain, and visual analogue scale (VAS) score.

Relationship between preterm, low birth weight and early childhood caries: a meta-analysis of the case-control and cross-sectional study.

Early childhood caries (ECC) is one of the most prevalent chronic infectious diseases in children. The effective prevention and treatment are heavy burdens and study hotspots for pediatric dentists. Many studies had investigated the relationship between preterm, low birth weight (LBW) and ECC; however, the results were inconsistent.

Clinical attachment level gain of lasers in scaling and root planing of chronic periodontitis: a network meta-analysis of randomized controlled clinical trials.

The objective of this study was to evaluate the clinical attachment level (CAL) gain of Er:YAG, Er,Cr; YSGG, Nd:YAG; and diode laser (DL) as monotherapy or adjunctive to scaling and root planing (SRP) of chronic periodontitis by network meta-analysis (NMA). Randomized controlled clinical trials (RCTs) about lasers applied in SRP of chronic periodontitis were searched from PubMed, Cochrane Library, Web of Science, Ovid, Science Direct, Wan Fang, and China National Knowledge Infrastructure (CNKI) databases up to September 2018 and from references of selected full-texts and related reviews. Standard mean differences and 95% confidence intervals were counted for CAL gain.

Impact of XPF rs2276466 polymorphism on cancer susceptibility: a meta-analysis.

Association between the xeroderma pigmentosum complementation group F (XPF)rs2276466 located in the excision repair cross complementation group 4 (ERCC4) gene and cancer susceptibility has been widely investigated. However, results thus far have remained controversial. A meta-analysis was performed to identify the impact of this polymorphism on cancer susceptibility.

Role of and polymorphisms in different outcomes upon Hepatitis B virus infection and prognosis to lamivudine therapy.

, having been found expressing differently in liver tissues in our previous work, including and , which are structural homologs named and Recent studies have indicated that involved in the development and proliferation of HepG2 cell, and may be associated with tumor susceptibility. Based on this, we tested the effects of and single-nucleotide polymorphisms for all major Hepatitis B virus (HBV) outcomes and lamivudine (LAM) treatment in Han Chinese. A total of 1649 samples were enrolled, and peripheral blood samples were collected in the present study.

The association of matrix metalloproteinase-9 promoter polymorphisms with gastric cancer risk: a meta-analysis.

Purpose: A variety of studies have observed that the single nucleotide polymorphisms (SNPs) matrix metalloproteinase-9 (MMP-9) gene may be associated with the risk of gastric cancer(GC), and a cytosine (C) to thymine (T) mutation at the -1562 site of the MMP-9 gene promoter is reported to be closely related to the susceptibility. However, because of the conflicting results of these studies, we undertook a systematic meta-analysis to assess the association between the SNPs and the risk of gastric cancer.

Materials And Methods: A computerised literature search was conducted within the databases of PubMed, EMBASE, and ISI Web of Knowledge for studies on the genetic association of MMP-9-1562C/T and gastric cancer published from 2004 to 2015.

Correlation between polymorphisms in DNA mismatch repair genes and the risk of primary hepatocellular carcinoma for the Han population in northern China.

Purpose: This study investigated correlations between polymorphisms in DNA mismatch repair (MMR) genes and the risk of primary hepatocellular carcinoma (PHC).

Methods: Single nucleotide polymorphisms (SNPs) in the DNA MMR genes MLH3 (rs175080), PMS1 (rs5742933), PMS2 (rs1059060), MSH3 (rs26279), MSH5 (rs1150793, rs2075789) and MSH6 (rs1042821) were detected using the SNaPshot method in 250 PHC cases and in 308 patients without PHC in the Han population in northern China.

Results: The AA genotype in MLH3 (rs175080) increased the risk of PHC (odds ratio [OR] = 3.

Regulation of iNOS expression by NF-κB in human lens epithelial cells treated with high levels of glucose.

Purpose: To explore the regulation of inducible nitric oxide synthase (iNOS) expression by nuclear factor kappa B (NF-κB) in human lens epithelial cells (LECs) treated with high levels of glucose, and to elucidate the impact of this in the pathogenesis of cataracts associated with diabetes.

Methods: LECs (SRA01/04) were cultured in vitro. NF-κB nuclear translocation and iNOS expression were measured at different glucose concentrations and at various time points, and the optimal concentration for detecting changes in the patterns of NF-κB nuclear translocation and iNOS expression was chosen.

Association of the rs3077 and rs9277535 polymorphisms in HLA-DP with hepatitis B virus infection and spontaneous clearance: a meta-analysis.

Purpose: Owing to inconsistent observations in the literature of an association between HLA-DP polymorphisms (rs3077 and rs9277535) and hepatitis B virus (HBV) infection and spontaneous clearance, there is an urgent need for a comprehensive and reliable understanding of this subject. This meta-analysis was performed to quantitatively summarise the evidence for the relevance of these HLA-DP polymorphisms to HBV infection and spontaneous clearance.

Methods: A meta-analysis was conducted with the data from eight relevant papers published from April 2009 to March 2012, following strict selection.

Peroxynitrite-induced nitration of cyclooxygenase-2 and inducible nitric oxide synthase promotes their binding in diabetic angiopathy.

Cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) play crucial roles in diabetic angiopathy. In vivo, however, the following facts remain unknown: whether COX-2 and iNOS bind, how peroxynitrite-induced nitration of COX-2 and iNOS affects their binding if they do bind and what effects of this mechanism contribute to diabetic angiopathy. This study focused on the issues above.
