Background The Toll-like receptor plays an essential role in controlling immunity and inflammation. This study was to investigate the relationships of genetic variants in TLR2 and TLR3 with hepatitis B virus (HBV) natural clearance and HBV-related hepatocellular carcinoma (HCC) risk in a Chinese male population. Methods We analyzed 5 polymorphisms of TLR2 (rs3804099 and rs3804100) and TLR3 (rs5743305, rs3775296 and rs3775291) in a population consisting of 686 participants with HBV natural clearance, 293 chronic HBV carriers and 395 HBV-positive HCC patients, using the improved multiplex ligase detection reaction method. Results After adjustment for age and smoking and drinking status, no associations were observed either between the 5 single-nucleotide polymorphisms (SNPs) and the HBV natural clearance participants, or between the 5 SNPs and HCC patients. Whereas the stratified analysis showed that under the dominant models, nondrinkers with TLR2 rs3804100 and participants younger than 40 years old with TLR3 rs3775291 were significantly associated with HCC risk when compared with persistent HBV carriers (adjusted odd ratio [OR] = 0.49, 95% confidence interval [95% CI], 0.31-0.78, p = 0.003; and adjusted OR = 0.50, 95% CI, 0.29-0.86, p = 0.013, respectively). Furthermore, the TTTCT haplotype was found to promote the progress of HBV clearance and inhibit development of HBV-related HCC (OR = 0.77, 95% CI, 0.61-0.97, p = 0.029; and OR = 0.72, 95% CI, 0.55-0.94, p = 0.016, respectively). And the CCACC and CCTCT haplotypes were observed to decrease susceptibility to HCC (OR = 0.64, 95% CI, 0.40-1.00, p = 0.048; and OR = 0.43, 95% CI, 0.28-0.68, p<0.001, respectively). Conclusions This study revealed that TLR2 rs3804100 and TLR3 rs3775291 polymorphisms may be protective factors for HBV-related HCC.

AbstractBackgroundFat mass and obesity-associated (FTO) gene is an obesity susceptibility gene and its relationship with the nonalcoholic fatty liver disease (NAFLD) remains unclear. This study aims to investigate the relationships of FTO gene variations with NAFLD risk in a Chinese male population.MethodsA 1:2 matched case–control study was performed on 275 cases of NAFLD and 550 controls matched for age. Nine of the FTO gene single nucleotide polymorphisms (SNPs) were genotyped.ResultsLogistic regression analysis found that FTO rs1477196 was significantly associated with the susceptibility to NAFLD in recessive genetic models [unadjusted odds ratio (OR) = 2.52, 95% confidence interval (CI): 1.22–5.19, P = 0.012] and the relativity weakened after further adjustment for body mass index (BMI), uric acid, metabolic syndrome, smoking, and drinking (adjusted OR = 2.18, 95% CI: 0.96–4.99, P = 0.06). In the obese group, the AA + AG genotypes of rs1121980 and rs9940128 were associated with a decreased risk of NAFLD, when compared with the GG genotype, respectively (rs1121980: adjusted OR = 0.62, 95% CI = 0.39–0.99, P = 0.044; rs9940128: adjusted OR = 0.61, 95% CI = 0.38–0.97, P = 0.038). Furthermore, rs1477196 was associated with the severity of NAFLD (OR = 2.95, 95% CI = 1.09–7.94, P = 0.034).ConclusionsOur results demonstrated that the FTO gene was related to the presence and severity of NAFLD in a Chinese male population, and the relationships of the tested SNPs with NAFLD are most probably mediated by BMI.

Background/Aims: Hepatocellular carcinoma (HCC) is a lethal disease with nearly equal morbidity and mortality. Thus, the discovery and application of more useful predictive biomarkers for improving therapeutic effects and prediction of clinical outcomes is of crucial significance. Methods: A total of 475 HBV-related HCC patients were enrolled. Ataxin 7 (ATXN7) single nucleotide polymorphisms (SNPs) were genotyped by Sanger DNA sequencing after PCR amplification. The associations between ATXN7 SNPs and mRNA expression with the prognosis of HBV-related HCC were analyzed. Results: In all, rs3774729 was significantly associated with overall survival (OS) of HBV-related HCC (P = 0.013, HR = 0.66, 95% CI: 0.48-0.94). And patients with the AA genotype and a high level of serum alpha fetoprotein (AFP) had significantly worse OS when compared to patients with AG/GG genotypes and a low level of AFP (adjusted P = 0.007, adjusted HR = 1.83, 95% CI = 1.18-2.82). Furthermore, low expression of ATXN7 was significantly associated with poor recurrence-free survival (RFS) and OS (P = 0.007, HR = 2.38, 95% CI = 1.27-4.45 and P = 0.025, HR = 1.75, 95% CI = 1.18-2.62). Conclusion: ATXN7 may be a potential predictor of post-operative prognosis of HBV-related HCC.

Abstract Objective To investigate the relationship between single nucleotide polymorphisms (SNPs) of the interleukin-4 (IL-4) gene and outcome of hepatitis B virus (HBV) infection in a Chinese Han population. Methods Total of 501 patients with chronic hepatitis B virus (HBV) infection and 301 controls with selflimiting HBV infection were studied. Three tag SNPs in the IL-4 gene (rs2227284G/T, rs2243283C/G and rs2243288A/G) were genotyped by the Multiplex snapshot technique. The genotype and allele frequencies were calculated and analyzed. Results The three SNPs showed no significant genotype/allele associations with chronic HBV infection. Overall allele P values were: rs2227284, P = 0.655, odds ratio (OR) [95% confidence interval (CI)] = 1.070 (0.793-1.445); rs2243283, P = 0.849, OR (95% CI) = 0.976 (0.758-1.257); rs2243288, P = 0.659, OR (95% CI) = 1.060 (0.818-1.375). Overall genotype P values were: rs2227284, P = 0.771; rs2243283, P = 0.571; rs2243288, P = 0.902. There were no statistically significant differences between patients with chronic HBV infection and controls. Haplotypes generated by these three SNPs also had no significant differences between the two groups. Conclusions The three tag SNPs of IL-4 were not associated with the outcome of HBV infection in the Han Chinese population.

Paediatric Uveitis

AimsWe aimed to determine whether paediatric idiopathic uveitis (PIU) and juvenile idiopathic arthritis associated paediatric uveitis (JIA-PU) have an association with Toll-like receptor 10 (TLR10) gene polymorphisms in Han Chinese.MethodsTen tag single nucleotide polymorphisms (SNPs) of TLR10 were analysed in 992 PIU patients, 127 JIA-PU patients and 1600 controls using the Sequenom MassARRAY system and iPLEX Gold assay. Genotype and allele frequencies were analysed using the χ2 test. A stratified analysis was performed according to the clinical features of PIU.ResultsIncreased frequencies of the rs2101521 A allele, rs10004195 A allele, rs11725309 CC genotype and rs6841698 AA genotype were found in PIU patients compared with controls (corrected p values (Pc)=1.81×10-4, Pc= 1.12×10-2, Pc=2.41×10-2 and Pc=3.29×10-3, respectively). There was no association between these 10 tag SNPs and JIA-PU. In the stratified analysis, the frequency of the rs6841698 A allele was higher in PIU patients with cataract (Pc=1.45×10-6). The frequencies of the rs2101521 A allele and rs6841698 AA genotype were increased in PIU patients with band keratopathy (BK) (Pc=2.32×10-2, Pc=3.30×10-3, respectively).ConclusionTLR10 gene polymorphisms (rs2101521, rs10004195, rs11725309 and rs6841698) confer susceptibility to PIU in Han Chinese. In a stratified analysis, rs2101521 and rs6841698 are associated with PIU with BK, and rs6841698 correlates with PIU with cataract.
