Abstract
Background Polymorphisms of genes encoding components of the vitamin D pathway including vitamin D receptor (VDR) and vitamin D binding protein (DBP) have been widely investigated because of the complex role played by vitamin D in cancer tumorogenesis. In this study, we investigated the association between VDR and DBP gene polymorphisms and HBV-related HCC risk in a Chinese population. Methods Study subjects were divided into three groups: 184 HBV patients with HCC, 296 HBV patients without HCC, and 180 healthy controls. The VDR rs2228570, and rs3782905 and the DBP rs7041 polymorphisms were genotyped using PCR-RFLP and the VDR rs11568820 polymorphism was genotyped by PCR-SSP, respectively. DNA sequencing was performed to validate the genotype results. Results We found that there were significant differences in the genotype and allele frequencies of the VDR rs2228570 and DBP rs7041 polymorphisms between HBV patients with HCC and healthy controls. The rs2228570 T allele was associated with a significant increased HBV-related HCC risk as compared with the C allele. The rs2228570 TT and TT/TC genotypes were correlated with a significant increased HBV-related HCC risk when compared with the wild-type CC homozygote. Similarly, the rs7041 G allele was associated with a significant increased HBV-related HCC risk as compared with the T allele. The rs7041 GG and GG/TG genotypes were correlated with a significant increased HBV-related HCC risk when compared with the wild-type TT homozygote. However, we did not observe any significant effect of VDR rs11568820, and rs3782905 polymorphisms on HBV-related HCC risk in this population. In haplotype analysis, we also did not find any significant differences in haplotype frequencies of the VDR gene between HBV patients with HCC and the healthy controls. Conclusions We conclude that the VDR rs2228570 and DBP rs7041 polymorphisms may contribute to increased susceptibility to HBV-related HCC in the Chinese population. Due to the marginal significance, further large and well-designed studies in diverse ethnic populations are needed to confirm our results.

Abstract
Background Epidermal growth factor (EGF) plays a pivotal role in cell proliferation, differentiation, and tumorigenesis of epithelial tissues. Variation of the EGF +61A/G (rs4444903) can lead to an alteration in EGF production and/or activity, which may result in individual susceptibility to gastric cancer. Studies investigating the association between EGF +61A/G polymorphism and gastric cancer risk produced inconsistent results. The aim of this study was to quantitatively summarize the evidence for such an association. Methods Eligible studies on the association between EGF +61A/G polymorphism and gastric cancer risk were identified by search of electronic databases including PubMed, EMBASE, Cochrane Library, and Chinese Biomedical Literature database (CBM). Data were extracted by two independent authors and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association. Metaregression and subgroup analyses were performed to identify the source of heterogeneity. Results Finally, six case–control studies with 1547 gastric cancer cases and 2762 controls were eventually identified. Overall, significant increased gastric cancer risk was found when all studies were pooled in the meta-analysis (GG vs. AA: OR = 1.438, 95% CI 1.021–2.025, P = 0.038; GG + AG vs. AA: OR = 1.256, 95% CI 1.025–1.539, P = 0.028; GG vs. AG + AA: OR = 1.265, 95% CI 1.002–1.596, P = 0.048). In subgroup analysis by ethnicity, source of control, study quality, and HWE in controls, significant increased gastric cancer risk was observed in Asians, population-based studies, high quality studies, and studies consistent with HWE. In subgroup analysis according to tumor location, and histological type, significant association was observed in all subgroups. Conclusions This meta-analysis suggested that the EGF +61A/G polymorphism contributes to increased gastric cancer risk, especially in Asian populations. Further well-designed studies based on large sample size in diverse populations are needed to confirm this association.

Abstract
BACKGROUND Interleukin-12 (IL-12) is a multifunctional cytokine that induces interferon (IFN)-γ secretion and plays an important role in antitumor immunity. The IL-12B +1188A/C polymorphism was found to correlate with a decreased cytokine production and/or activity, which may lead to increased susceptibility to cancers including hepatocellular carcinoma (HCC). Previous epidemiological studies investigating the association between IL-12B +1188A/C polymorphism and HCC risk reported inconsistent results. We performed a meta-analysis to derive a precise estimation of the association. METHODS All studies published up to July 2014 on the association between IL-12B +1188A/C polymorphism and HCC risk were identified by searching electronic databases including PubMed, Embase, Cochrane library, and Chinese Biomedical Literature database (CBM). Data were extracted by two independent authors and the odds ratios (ORs) together with corresponding 95% confidence intervals (CIs) were used to assess the association between IL-12B +1188A/C polymorphism and HCC risk. RESULTS Five studies with 1864 cases and 2077 controls were included in the meta-analysis. We observed that the IL-12B +1188A/C polymorphism was significantly correlated with increased HCC risk when all studies were pooled into the meta-analysis (CC vs. AA: OR=1.306, 95% CI 1.063-1.606, P=0.011; AC vs. AA: OR=1.193, 95% CI 1.014-1.405, P=0.034; CC+AC vs. AA: OR=1.260, 95% CI 1.098-1.445, P=0.001). In subgroup analyses by ethnicity, source of control, and study quality, significant increased HCC risk was found in Asians, hospital-based studies, and high quality studies. CONCLUSIONS The present meta-analysis suggests that the IL-12B+1188A/C polymorphism is a low-penetrant risk factor for HCC development, especially among Asians. Further large and well-designed studies are needed to confirm this association.

Abstract
Genetic polymorphisms of xeroderma pigmentosum group D (XPD) in the nucleotide excision repair pathway may influence cancer susceptibility by affecting the capacity for DNA repair. Studies investigating the association between XPD Lys751Gln and Asp312Asn polymorphisms and hepatocellular carcinoma (HCC) risk reported inconsistent results. The aim of this study was to quantitatively summarize the evidence for such an association. Eligible studies were identified by searching electronic databases including PubMed, Embase, Cochrane library, and CBM, Chinese Biomedical Literature Database, for the period up to October 2014. The association of XPD Lys751Gln and Asp312Asn polymorphisms and HCC risk was assessed by odds ratios (ORs) together with their 95% confidence intervals (CIs). Finally, a total of 11 studies with 4322 cases and 4970 controls were included for XPD Lys751Gln polymorphism and 6 studies with 2223 cases and 2441 controls were available for XPD Asp312Asn polymorphism. With respect to XPD Lys751Gln polymorphism, statistically significant increased HCC risk was found when all studies were pooled into the meta-analysis (Gln/Gln vs Lys/Lys: OR = 1.363, 95% CI 1.065-1.744, P = 0.014; Lys/Gln vs Lys/Lys: OR = 1.205, 95% CI 1.099-1.321, P = 0.000; Gln/Gln+Lys/Gln vs Lys/Lys: OR = 1.300, 95% CI 1.141-1.480, P = 0.000). In subgroup analyses by ethnicity, source of control, Hardy-Weinberg equilibrium (HWE) in controls, hepatitis B virus (HBV) infection, and statistically significant increase of HCC risk was found in East Asians, population-based studies, studies consistent with HWE, and HBV-positive subjects, but not in mixed/other populations, hospital-based studies, studies deviating from HWE, and HBV-negative subjects. With respect to XPD Asp312Asn polymorphism, no significant association with HCC risk was found in the overall and subgroup analyses. The results suggest that the XPD Lys751Gln polymorphism contributes to increased HCC susceptibility, especially in East Asian populations. Further, large and well-designed studies are required to validate this association.

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that function as tumor suppressors or oncogenes. Single nucleotide polymorphisms (SNPs) located in the miRNAs influence the function of mature miRNAs and may contribute to cancer development. Studies investigating the association between miR-146a rs2910164 and miR-196a2 rs11614913 polymorphisms and hepatocellular carcinoma (HCC) risk reported inconsistent results. We performed a meta-analysis of all available studies to summarize this situation. Eligible studies were identified by search of electronic databases including PubMed, Embase, and Cochrane library for the period up to August 2014. The association of miR-146a rs2910164 and miR-196a2 rs11614913 polymorphisms and HCC risk was assessed by odds ratios (ORs) together with their 95% confidence intervals (CIs). Finally, a total of 12 studies with 4171 cases and 4901 controls were included for miR-146a rs2910164 polymorphism and 10 studies with 4687 cases and 4990 controls were available for miR-196a2 rs11614913 polymorphism. With respect to miR-146a rs2910164 polymorphism, statistical significant increased HCC risk was found when all studies were pooled into the meta-analysis (GG+CG vs CC: OR = 1.097, 95% CI 1.005-1.197, P = 0.037). In subgroup analyses by ethnicity, source of control, and HWE in controls, significant increase of HCC risk was found in Asians, population-based studies, and studies consistent with HWE, but not in Caucasians, hospital-based studies, and studies inconsistent with HWE. With respect to miR-196a2 rs11614913 polymorphism, no significant association with HCC risk was found in the overall and subgroup analyses. The results suggest that the miR-146a rs2910164 polymorphism contributes to increased HCC susceptibility, especially in Asian populations. Further large and well-designed studies are required to validate this association.

Abstract
Background The null genotype of GSTM1 have been implicated in gastric cancer risk, but numerous individual studies showed mixed, or even conflicting results. Thus, a meta-analysis was performed. Results We identified 54 individual studies involving 9,322 cases and 15,118 controls through computer-based searches of PubMed, Embase, and Cochrane Library. It was found that the null genotype of GSTM1 was associated with an increased gastric cancer risk (OR = 1.207, 95% CI: 1.106-1.317, P < 0.001), under the random-effects model (I2 : 49.9%, PQ <0.001). From stratification analyses for ethnicity, alcohol drinking, Helicobacter pylori infection, an effect modification of gastric cancer risk was found in the subgroups of ethnicity, smoking status, Helicobacter pylori infection, whereas null result was found in the subgroups of alcohol drinking. We also undertook gene-gene interaction analysis between GSTM1 and GSTT1 genes for gastric cancer risk, and the results indicated that the dual null genotypes of GSTM1 and GSTT1 might elevate the risk of gastric cancer (OR = 1.505, 95% CI: 1.165-1.944, P = 002). Conclusions This meta-analysis suggests that the null genotype of GSTM1 may be a important genetic risk factor for gastric cancer development.

Abstract
Background Interleukin-4 (IL-4) is best known as an important mediator and modulator of immune and inflammatory responses. Hepatocellular carcinoma (HCC) is a typical inflammation-related cancer, and genetic variations in the IL-4 gene may be associated with the risk of hepatitis B virus (HBV)-related HCC. However, few studies have been conducted on their association. Objectives To clarify the effects of IL-4 gene polymorphisms on the risk of HBV-related HCC, two common variants, −590C/T (rs2243250) and −33C/T (rs2070874), and their relationship with HBV-related disease risk were investigated in a Chinese population. Methods IL-4 −590C/T and −33C/T polymorphisms were examined in 154 patients with HBV-related HCC, 62 patients with HBV-induced liver cirrhosis (LC), 129 patients with chronic hepatitis B (CHB), and 94 healthy controls, using the polymerase chain reaction-restriction fragment length polymorphism method and DNA sequencing. Results Overall, no significant differences were observed regarding the IL-4 −590C/T and −33C/T polymorphism genotypes, alleles, or haplotypes between the patient groups and the healthy controls. However, the CC genotypes of IL-4 −590C/T and −33C/T polymorphisms were observed to be significantly associated with CHB in subgroup analysis in males [CC versus TT (OR: 4.193, 95% CI: 1.094–16.071, P = 0.037; and OR: 3.438, 95% CI: 1.032–11.458, P = 0.044) and CC versus TT+CT (OR: 4.09, 95% CI: 1.08–15.49, P = 0.038; and OR: 3.43, 95% CI: 1.04–11.28, P = 0.042)]. Conclusions These findings suggest that genetic variants in IL-4 −590C/T and −33C/T polymorphisms may be a risk factor for CHB in Chinese males but not for HBV-related LC or HCC.

Abstract
Background Recent epidemiological evidence points to an association between gallstones or cholecystectomy and the incidence risk of liver cancer, but the results are inconsistent. We present a meta-analysis of observational studies to explore this association. Methods We identified studies by a literature search of PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and relevant conference proceedings up to March 2014. A random-effects model was used to generate pooled multivariable adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Between-study heterogeneity was assessed using Cochran’s Q statistic and the I2. Results Fifteen studies (five case-control and 10 cohort studies) were included in this analysis. There were 4,487,662 subjects in total, 17,945 diagnoses of liver cancer, 328,420 exposed to gallstones, and 884,507 exposed to cholecystectomy. Pooled results indicated a significant increased risk of liver cancer in patients with a history of gallstones (OR = 2.54; 95% CI, 1.71–3.79; n = 11 studies), as well as cholecystectomy (OR = 1.62; 95% CI, 1.29–2.02; n = 12 studies), but there was considerable heterogeneity among these studies. The effects estimates did not vary markedly when stratified by gender, study design, study region, and study quality. The multivariate meta-regression analysis suggested that study region and study quality appeared to explain the heterogeneity observed in the cholecystectomy analysis. Conclusions Our results suggest that individuals with a history of gallstones and cholecystectomy may have an increased risk of liver cancer.

Abstract
BACKGROUND The aim was to calculate the two-sided 95th percentile reference values for blood urea nitrogen (BUN) and serum creatinine (SCr) in Chinese Han ethnic adult men. METHODS Serum samples were collected from Chinese Han ethnic adult men aged 20 - 69 years. After screening based on the inclusion and exclusion criteria, a total of 1575 individuals were enrolled in our study. BUN and SCr values were measured on an automatic analyzer (Dade Behring, USA). The data was analyzed and calculated using nonparametric statistical methods. RESULTS BUN and SCr values were not normally distributed. The reference values were in the range 3.3 - 7.5 mmol/L for BUN and 64 - 113 micromol/L for SCr. BUN levels were significantly lower in the smoking group than the non-smoking group (Z = -4.52, p < 10(-5)). An increase with age was observed in BUN levels (r(s) = 0.172, p < 0(-5)) and lower SCr levels were weakly associated with the older subjects (r(s) = -0.071, p = 0.005). Moreover, it was found that higher Body Mass Index (BMI) tended toward higher levels of SCr (r(s) = 0.118, p < 10(-5)). CONCLUSIONS The reference values established for BUN and SCr exhibit a slight deviation compared to those developed in previous studies. We propose reference values of BUN for smokers and non-smokers be constructed, and age- and BMI-specific reference values be applied in clinical laboratories.

Abstract
BACKGROUND The aim of this study was to set a reference interval (RI) for osteocalcin (OC) in a healthy Han male population from the Fangchenggang Area Male Health and Examination Survey (FAMHES) project and study the effects of age, BMI, smoking, and alcohol consumption. METHODS We used data from 2018 Han ethnic males who participated in FAMHES project from September 2009 to December 2009. Serum OC values were measured by electrochemiluminescence immunoassay on COBAS 6000 system E601 (Elecsys module) immunoassay analyzers. RESULTS OC data does not have a normal distribution or Gaussian pattern (Z = 3.791, p < 0.001). After log-transformation, data took on a normal, Gaussian distribution (Z = 0.968, p = 0.306). The RI of serum OC was 12.49 - 43.94 ng/mL. No difference in OC concentration was noted either between non-smoker or smoker groups (p = 0.629) or non-drinker and drinker groups (p = 0.748). OC levels varied with age (r = -0.371, p < 0.001) and BMI (r = -0.331, p < 0.001), and the age-dependent and BMI-dependent RIs were calculated. CONCLUSIONS The RIs for serum OC exhibit slight differences compared to previously reported reference ranges. Age-dependent and BMI-dependent RIs for serum OC should be implemented in clinical laboratories.

Abstract
Previous studies have demonstrated that hypoxia-inducible factor-1a (HIF-1a) may play a vital role in the pathogenesis of hepatocellular carcinoma (HCC). However, the relationship between HIF-1a polymorphisms and HCC has not been thoroughly investigated. The aim of this study is to determine whether HIF-1a polymorphisms are associated with HCC through a case-control study. Two polymorphisms in the HIF-1a gene (rs11549465 and rs115494657) were examined in 157 hepatitis B virus (HBV)-related HCC patients and 173 healthy controls using the polymerase chain reaction-restriction fragment length polymorphism method. DNA sequencing was used to validate genotype results. There were no significant differences in the genotype and allele frequencies of HIF-1a rs11549465 and rs115494657 polymorphisms between the HBV-related HCC patients and healthy controls. However, the data revealed that subjects with the CG haplotype have a higher susceptibility to HBV-related HCC [odds ratio (OR)=2.327, 95% confidence interval (CI)=1.578-4.721, P=0.008]. In contrast, the CA haplotype was associated with a significantly decreased risk of HBV-related HCC (OR=0.416, 95% CI=0.172-0.910, P=0.025). HIF-1a rs11549465 and rs115494657 polymorphisms appeared to be irrelevant to HBV-related HCC. However, the HIF-1a CG and CA haplotypes might be a risk factor and a protective marker, respectively, for HBV-related HCC in a Chinese population. Further investigations with a larger sample size may be required to validate the genetic effects of HIF-1a polymorphisms on HBV-related HCC.

Abstract
Only a small proportion of genetic variation in serum ferritin has been explained by variant genetic studies, and genome-wide association study (GWAS) for serum ferritin has not been investigated widely in Chinese population. We aimed at exploring the novel genetic susceptibility to serum ferritin, and performed this two stage GWAS in a healthy Chinese population of 3,495 men aged 20–69 y, including 1,999 unrelated subjects in the first stage and 1,496 independent individuals in the second stage. Serum ferritin was measured with electrochemiluminescence immunoassay, and DNA samples were collected for genotyping. A total of 1,940,243 SNPs were tested by using multivariate linear regression analysis. After adjusting for population stratification, age and BMI, the rs5742933 located in the 5′UTR region of PMS1 gene on chromosome 2 was the most significantly associated with ferritin concentrations (P-combined = 2.329×10−10) (β = −0.11, 95% CI: −0.14, −0.07). Moreover, this marker was about 200kb away from the candidate gene SLC40A1 which is responsible for iron export. PMS1 gene was the novel genetic susceptibility to serum ferritin in Chinese males and its relation to SLC40A1 needs further study.

INFECTION GENETICS AND EVOLUTION 2014; 27:375-81.

Abstract
BACKGROUND AND OBJECTIVE Interleukin-2 (IL-2) is an immunoregulatory cytokine produced by T cells and plays an important role in antitumor immunity. Variations in the DNA sequence of the IL-2 gene may lead to altered cytokine production and/or activity, and thus modulate an individual's susceptibility to hepatitis B virus-related hepatocellular carcinoma (HBV-related HCC). To test this hypothesis, we investigated whether IL-2 gene polymorphisms and its serum levels are associated with HBV-related HCC in a Chinese population. METHODS The +114T/G and -384T/G polymorphisms in the IL-2 gene were examined in 115 cases of chronic hepatitis B (CHB), 67 cases of HBV-related liver cirrhosis (LC), 107 cases of HBV-related HCC, and 105 healthy controls by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. The serum IL-2 levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS We found that there were significant differences in the genotype and allele frequencies of the IL-2 gene +114T/G polymorphism between the HBV-related HCC patients and the healthy controls. The +114 TG and GG genotypes were associated with a significant increased HCC risk as compared with the TT genotype (OR=1.988, 95% CI, 1.034-3.480, P=0.009 for TG genotype, and OR=1.975, 95% CI, 1.012-3.341, P=0.013 for GG genotype, respectively). The +114 G allele was correlated with a significant increased HCC risk as compared with the T allele (OR=1.423, 95% CI, 1.023-1.975, P=0.031). In addition, we found significant decreased serum IL-2 in HBV-related HCC patients (288.6±177.1ng/L) compared with healthy controls (238.2±136.7ng/L) (t=2.32, P=0.021). Genotypes carrying the +114 G variant allele were associated with decreased serum IL-2 levels compared with the homozygous wild-type genotype in HBV-related HCC patients. CONCLUSION The results suggested that the IL-2 +114T/G polymorphism may contribute to increased HBV-related HCC risk through regulating the serum IL-2 levels. Further large and well-designed studies in diverse ethnic populations are needed to confirm our results.
