Background: Previous studies have indicated a direct effect of μ-opioid receptors on tumor progression or recurrence. An A118G polymorphism in the μ-opioid receptor gene was believed to play an important role in this carcinogenic process. The aim of the present study was to investigate the association between the A118G polymorphism and the risk of esophageal squamous cell carcinoma (ESCC) in a Chinese population.
Method: The case-control study included 260 cancer patients and 291 controls from a Chinese Han and Chinese TuJia population in Enshi region, China. Genotypes were determined by TaqMan platform. Odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated using multivariate unconditional logistic regression.
Results: Compared with the G/G genotype, the A/A genotype exhibited a significantly elevated risk for ESCC (OR = 3.12, 95 % CI [1], 1.11-6.01). A significant interaction between the A118G polymorphism and age, smoking status, and family history of cancer was also found (OR = 2.25, 95 % CI 1.36-4.12; OR = 1.75, 95 % CI 1.23-2.32; OR = 3.14, 95 % CI 1.31-7.28, respectively).
Conclusion: The A118G polymorphism in the μ-opioid receptor gene might be associated with the risk of ESCC in Chinese population.

Background: IL4 is a versatile cytokine essentially known for differentiation, proliferation and cell death in cells. Its dysregulation has been found to be associated with the development of inflammatory disorders.
Objective: The goal of the current investigation is to identify and select non-synonymous single-nucleotide polymorphisms (nsSNPs) in the IL-4 gene by employing computational methods which may have a potential functional impact on the occurrence of disease.

Knowledge about determinants of addiction in people taking addictive substances is poor and needs to be supplemented. The novelty of this paper consists in the analysis of innovative aspects of current research about relationships between determinants of addiction in Polish patients taking addictive substances and rare available data regarding the relationships between these factors from studies from recent years from other environments, mainly in Europe, and on the development of genetic determinants of physiological responses. We try to explain the role of the microelements Mn, Fe, Cu, Co, Zn, Cr, Ni, Tl, Se, Al, B, Mo, V, Sn, Sb, Ag, Sr, and Ba, the toxic metals Cd, Hg, As, and Pb, and the rare earth elements Sc, La, Ce, Pr, Eu, Gd, and Nd as factors that may shape the development of addiction to addictive substances or drugs.

Tramdol is one of most popular opioids used for postoperative analgesia worldwide. Among Arabic countries, there are reports that its dosage is not appropriate due to cultural background. To provide theoretical background of the proper usage of tramadol, this study analyzed the association between several genetic polymorphisms (CYP2D6/OPRM1) and the effect of tramadol.

Background: Rheumatoid arthritis (RA) is a multisystem inflammatory disorder. Family history of RA is an important risk factor as it is strongly linked with the inherited HLA-DR4 (most specifically DR0401 and 0404). The aim of this study is to conduct the haplotype-based analysis of 6q24-25 and evaluate its association with RA.

Aim: Abundant data are available on the effect of the A118G (rs1799971) single-nucleotide polymorphism (SNP) of the μ-opioid receptor OPRM1 gene on morphine and fentanyl requirements for pain control. However, data on the effect of this SNP on intraoperative remifentanil requirements remain limited. We investigated the effect of this SNP on intraoperative remifentanil requirements.
