Hepatocellular carcinoma (HCC) is the most common cancer type. There is a correlation between selenium (Se) deficiency and the incidence of HCC. To clarify the effects of Se level on the risk of HCC patients, a meta-analysis was performed. A total of 9 articles published between 1994 and 2016 worldwide were selected through searching PubMed, EMBASE, web of science, Cochrane Library, Springer Link, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM), and the information were analyzed using a meta-analysis method. Heterogeneity was assessed by using the I2 index. Publication bias was evaluated by Begg's Test analysis. Pooled analysis indicated that patients with HCC had lower Se levels than the healthy controls [standardized mean difference (SMD)= −1.08, 95% confidence intercal (CI) = (−0.136, −0.08), P < 0.001]. Further subgroup analysis showed this effect to be independent of the study design, race or sample collection. In conclusion, this meta-analysis suggested an inverse correlation between Se level and the risk of HCC in humans patients.

“…Therefore, it was thought that we should analyze the relationship between metal and sperm properties in the three groups. Most studies have analyzed single metals by titration [10,11] and AA [12,13]. Instead, we planned to simultaneously analyze a number of different metals in seminal plasma for a comprehensive study of the relationship between metal concentrations and sperm properties.…”

We have simultaneously determined the presence of 30 different trace metals in human seminal plasma by Inductively Coupled Plasma Mass Spectrometry (ICP−MS). To date, high concentrations of metals (e.g. Zn, Cu, Mg and Fe) in seminal plasma have been sporadically reported and only few reports have discussed the relationships between trace metals and human semen profiles. Ninety-four seminal plasma specimens were first classified in three groups (normozoospermia, oligozoospermia, and azoospermia) according to the WHO guideline for sperm concentration. No significant differences were found among the three groups for all the metals examined. The concentration of metals in the specimens were then compared with sperm concentration, motility, morphology, and volume using multivariate regression analysis, principal component analysis (PCA) and cluster analysis. The most cumulative contribution ratio and grouping were extracted for profile analysis. Zn showed a positive correlation with motility and morphology (r = 0.3142 and 0.6205), whereas trace metals such as Se and Tl showed positive correlations with all sperm properties. Heavy metals such as Cu, Cd, and Cr also showed high positive or negative correlations with sperm properties. In summary, this study is the first to report the simultaneous determination of metals (in addition to the commonly reported Zn), including trace and heavy metals, in human seminal plasma as analyzed by multivariate regression analysis.
