Background and Aims: We undertook this study to review and quantitatively analyze the association between human leukocyte antigen (HLA) DR polymorphisms and susceptibility of primary biliary cirrhosis (PBC). Methods: All relevant publications on the association between HLA-DR polymorphisms and PBC were searched through June 2013. Odds ratios (OR) and confidence intervals (CI) for the comparisons between case and control group were calculated. Statistical analysis was performed using Stata 11.0 software. Results: Nineteen articles (or 20 studies including the substudies) were identified. For DR*7 allele, the ORs (95% CIs) were 1.530 (1.310, 1.788), 1.757 (1.285, 2.403) and 1.495 (1.211, 1.845) in overall, Asian and European populations, respectively. For DR*8 alleles, the ORs (95% CIs) were 3.158 (1.822, 5.475), 2.803 (2.420, 3.247) and 3.056 (2.573, 3.629) in Asian, American and European subgroups, respectively. The subgroup analysis for DR*11 and DR*13 showed a significant association in Asian and European population. For DR*12 and *15 alleles, the overall ORs (95% CIs) were 0.551 (0.404, 0.753) and 0.721 (0.607, 0.857). However, in subgroup analysis for DR*12 allele, the association was only found in Asian population. In addition, statistical significance exists in American and European populations in the subgroup analysis for DR*15 allele. Conclusion: Our meta-analysis suggested that HLA-DR *7 and *8 allele polymorphisms contributed to the susceptibility of PBC, whereas DR*11, *12, *13 and *15 allele polymorphisms are protective factors in certain population. © 2014 IMSS.

Background and Aim: The cytotoxic T-lymphocyte antigen 4 (CTLA4) is an inhibitory receptor expressed on activated and regulatory T lymphocytes. Polymorphisms could have remarkable effects on susceptibility to autoimmunity. However, the associations between CTLA-4 polymorphisms and primary biliary cirrhosis (PBC) remain ambiguous. The aim of this meta-analysis is to determine more precise estimations of the relationship. Methods: From literature retrieval from PubMed, Web of Science, Science Direct, and the Chinese National Knowledge Infrastructure (CNKI) Database, the publications on the associations between rs231775, rs3087243, rs5742909, rs231725 and rs11571317 polymorphisms of CTLA4 and PBC through June 2011 were collected. Odds ratios (OR) with 95% confidence intervals (95% CI) were calculated in fixed or random model, I2 was calculated to examine heterogeneity, and funnel plots were plotted to examine small study effects with Revman 5.1 and Stata 11. Results: Overall, a significantly increased risk was found for G versus A allele for rs231775 (OR=1.28, 95% CI=1.17-1.41). For rs3087243, a significant association was found for AA versus GG genotype (OR=0.66; 95% CI=0.55-0.80). When subgroup analysis by ethnicity was performed, the same association was only found in Caucasians. For rs231725, the OR values (95% CI) for GG versus AA, GA versus AA and G versus A allele were 0.52 (0.40-0.68), 0.74 (0.60-0.92) and 0.73 (0.61-0.88). No significant associations were found for other polymorphisms. Conclusion: The G allele of rs231775 is a risk factor for PBC, while AA genotype of rs3087243 and GG, GA and G allele of rs231725 show negative associations with PBC. © 2012 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

Background: Susceptibility to tuberculosis is not only determined by Mycobacterium tuberculosis infection, but also by the genetic component of the host. Macrophage receptor with a collagenous structure (MARCO) is essential components required for toll like receptor-signaling in macrophage response to Mycobacterium tuberculosis, which may contribute to tuberculosis risk. Principal Findings: To specifically investigated whether single nucleotide polymorphisms (SNPs) in MARCO gene are associated with pulmonary tuberculosis in Chinese Han population. By selecting tagging SNPs in MARCO gene, 17 tag SNPs were identified and genotyped in 923 pulmonary tuberculosis patients and 1033 healthy control subjects using a hospital based case-control association study. Single-point and haplotype analysis revealed an association in intron and exon region of MARCO gene. One SNP (rs17009726) was associated with susceptibility to pulmonary tuberculosis, where the carriers of the G allele had a 1.65 fold (95% CI = 1.32-2.05, p corrected = 9.27E-5) increased risk of pulmonary tuberculosis. Haplotype analysis revealed that haplotype GC containing G allele of 17009726 and haplotype TGCC (rs17795618T/A, rs1371562G/T, rs6761637T/C, rs2011839C/T) were also associated with susceptibility to pulmonary tuberculosis (p corrected = 0.0001 and 0.029, respectively). Conclusions: Our study suggested that genetic variants in MARCO gene were associated with pulmonary tuberculosis susceptibility in Chinese Han population, and the findings emphasize the importance of MARCO mediated immune responses in the pathogenesis of tuberculosis. © 2011 Ma et al.

GINS2 has been found to be closely related to cell proliferation, survival and maintenance of genomic integrity in addition to the induction of polyploidy. However, the molecular mechanisms of GINS2-mediated tumor regression have not been fully elucidated. Our study showed that GINS2 interacted with PML-C (a structural domain of PML, which is a cutting product of PML-RAR) as demonstrated by yeast two-hybrid assay and co-immunoprecipitation, and PML (NLS-) also interacted with GINS2 by co-immunoprecipitation. Following transfection with plasmids expressing GINS2 siRNA, the apoptosis and cell cycle distribution were determined by flow cytometry. The results revealed that K562 chronic myelocytic leukemia cells and NB4 acute promyelocytic leukemia cells were arrested in the G2 phase. Western blot assay indicated that the expression of cyclin A, cyclin D1 and cyclin B1 was decreased, and cyclin B1 was localized in the cytoplasm after GINS2 knockdown as demonstrated by immunofluorescence staining. The expression of the apoptosis-related protein Bcl-2 was decreased but that of Bax was increased in the cells transfected with GINS2 siRNA. The percentage of apoptotic cells was increased as detected by flow cytometry. Our findings demonstrated that GINS2 plays an important role in apoptosis and may function via the p38MAPK signaling pathway. Source

The aim of the study was to compare the mid- and long-term effects of different treatments such as CT-guided percutaneous pulmonary paracentesis, tuberculoma perfusing chemotherapy and whole-body standard chemotherapy or extended chemotherapy on safety and effectiveness for pleural chemotherapy. A total of 60 subjects diagnosed to have pleural tuberculosis between February 2010 and February 2014 were prospectively selected for this study and were considered as the experimental group. Seventy pleural tuberculosis patients who underwent treatment between February 2006 and February 2010 were considered as the control group. The patients in the experimental group were treated with CT-guided percutaneous pulmonary paracentesis and tuberculoma perfusing chemotherapy of not more than three courses with each course consisting of administration of 0.1 g isoniazid, n 0.5 gkanamyci, 0.2 g levofloxacin, and 1 ml lidocaine once a week for four times. The patients in the control group were treated with whole-body standard or extended chemotherapy regimen 3~6HRZE(S)/6~12HR. The patients were followed up for 18 months and the treatment effects were compared. The diameter of tuberculoma in patients of the experimental group during 6, 12 and 18 months was shorter than that of the control group (P<0.05). The total effective rate of treatment and the duration of treatment in experimental group during 18 months were higher than that of control group (P<0.05). The frequency of drug-related complications were lower in comparison with the control group (P<0.05). No surgically acquired complications were observed in the experimental group. Thus, treatments such as CT-guided percutaneous pulmonary paracentesis and tuberculoma perfusing chemotherapy for pleural tuberculosis are safe and effective, which has greater value and can be promoted for use in the clinical setting. © 2016, Spandidos Publications.
