4.Association between cytotoxic T lymphocyte associated antigen-4 gene polymorphism and ankylosing spondylitis susceptibility: a meta-analysis
Chinese Journal of Rheumatology 2017;21(8):547-552
Objective To explore the association between cytotoxic T lymphocyte associated antigen-4 (CTLA-4) gene polymorphism and susceptibility to ankylosing spondylitis (AS). Methods The case-control studies from Chinese Biomedical Database, Chinese National Knowledge Infrastructure, Wanfang, Weipu, PubMed, Cochrane Library, OvidSP, Wiley Online Library, Elsevier Science Direct, Springer Link databases for the association of CTLA-4 gene polymorphism with AS. The association strength was assessed with chi-squared test by Stata 12.0 software. Results Seven references of CTLA-4 gene +49A/G (rs231775) polymorphism were enrolled which included 1119 AS patients and 995 controls (healthy subjects or non-AS patients), which showed that there were no statistical difference between AS and control groups under recessive, dominant, co-dominant, additive and allele gene models. Five references of CTLA-4 gene-318C/T (rs5742909) polymorphism were enrolled which included 635 AS patients and 512 controls, which showed that there were no statistical difference between AS and control groups under recessive and additive gene models; however, there were statistical difference between AS and control groups under dominant model [ OR=1.651, 95%CI (1.052, 2.590), P=0.029], co-dominant model [OR=0.621, 95%CI (0.403, 0.957), P=0.031] and allele model [OR=1.587, 95%CI (1.068, 2.357), P=0.022]. Conclusion The meta analysis reveal that CTLA-4 gene rs231775 single nucleotide polymorphism is not associated with the susceptibility to AS; rs5742909 SNP is associated with the susceptibility to AS, which suggests that C→T mutation increases the risk of AS.

Chinese Journal of Rehabilitation Theory and Practice 2003;9(4):250-251
ObjectiveTo explored the relationship among endothelin-1(ET-1), P-selection and troponin I(CTnI) in acute myocardial infarction (AMI) and unstable angina (UA).MethodsPlasma level of endothelin-1 was analyzed by radioimmunoassay, the expression of P-selection was analyzed by flow cytometery technique and troponin I was analyzed by paramagnetic partile chemiluminescent immunoassay in 23 AMI cases, 21 UA cases and 28 healthy controls.ResultsPlasma levels of ET-1 and CTnI in AMI patients were higher than in controls(P<0.05). The expression of P-selection in AMI patients was higher than in controls (P<0.01).Plasma levels of ET-1 and expression of P-selection in UA patients were higher than in controls (P<0.05). There was an increased trend of CTnI in UA patients in contrast to controls, but without statistical significance(P>0.05).As compared with UA, plasma levels of CTnI and expression of P-selection were elevated in AMI patients (P<0.05). No significant difference was observed between AMI and UA cases in plasma level of ET-1. Multivariate regression analysis revealed that P-selection was significantly associated with AMI and UA cases compared with plasma level of CTnI (r=0.404,P<0.01).ConclusionsPlasma levels of ET-1 and P-selection were sensitive markers as prethrombolic status.

Objectives: To explore the association between the polymorphism in -857 site of tumor necrosis factor (TNF)-α promoter region and the susceptibility to ankylosing spondylitis (AS). Methods: Case-control studies Pubmed, Cochrane Library, Ovid, Chinese Biomedical Database(CBM), Chinese National Knowledge In-frastructure(CNKI), Wanfang and Weipu data bases from inception to October 2013 for the association between TNF-α-857 C/T polymorphism and the susceptibility to AS were collected. Meta-analysis was performed by Revman 5.2 and Stata 12.0 software. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were de-rived from random-effects or fixed-effects models to assess the strength of the association. Results: Nine case-control studies were included in the final meta-analysis, including a total of 933 AS patients and 1094 controls. Statistically significant differences between AS and control groups were observed in the susceptibility to AS and TNF-α-857 genotype CC [OR=0.46, 95%CI (0.26, 0.81), P=0.007], allele C [OR=0.61, 95%CI (0.41, 0.91), P=0.02] and T [OR=1.64, 95%CI (1.10, 2.43), P=0.02]. But, no statistical difference in the fre-quency of genotype TT [OR=1.49, 95%CI (0.95, 2.34), P=0.08] was observed between AS and control groups. There were obvious heterogeneities among the studies of genotype CC(P<0.00001, I2=87%), allele C(P<0.00001, I2=84%) and allele T(P<0.00001, I2 =84%), except genotype TT(P=0.09, I2=42%). Sensitivity analysis was per-formed by leaving out one study at a time, but the heterogeneity remained obvious. It was symmetric of the funnel plots of genotype CC, allele C and T with AS, but genotype TT. There was no statistical significance in genotype CC[Begg′s test(z=0.52, P=0.602), Egger′s test(t=0.23, P=0.825)], genotype TT[Begg′s test(z=0.94, P=0.348), Egger′s test(t=1.26, P=0.248)], allele C[Begg′s test(z=0.31, P=0.754), Egger′s test(t=0.72, P=0.494)] or allele T[Begg′s test(z=0.31, P=0.754), Egger′s test(t=-0.72, P=0.494)]. Conclusions: Genotype CC, allele C and T of TNF-α-857 are associated with the susceptibility to AS, and T-allele carriers have higher risk of AS.

BACKGROUND: The preventative capabilities of enamel demineralization, rising from the fixed orthodontic treatment, have drawn tremendous attention in recent years. Despite a variety of investigations carried out by both domestic and foreign scholars, whereas, the results of ways to reduce the incidence of demineralization are never fully satisfactory or unified. OBJECTIVE: To evaluate the inhibitory effect of Fluor protector on enamel demineralization based on clinical practices during fixed orthodontic treatment.DESIGN, TIME AND SETTING: Contrast observation was performed in the Department of Stomatology, Qingdao Second Sanatorium, Jinan Military Area Command of Chinese PLA from January 2006 to January 2009. PARTICIPANTS: A total of 132 participants (856 teeth, aged 7-18 years, average age 10.5 years, 76 females and 56 males), who had wall-developed hardened dental tissues, no tetracycline pigmentation teeth, no dental fiuorosis, or anything that constricted in their teeth, were involved in the study. And all subjects were volunteers who had signed the informed consent form and agreed to receive dental treatment and periodic review.METHODS: All the teeth were randomly divided into two groups: experimental and control groups. Teeth for the experimental group were bonded with the supporting brackets with the Fluor protectors, whereas teeth for the control group did basically the same only without the Fluor protectors. After the fixed orthodontic treatment, the supporting devices were removed, all the teeth were fully washed, and then the conditions of the tooth surfaces were observed and documented in both experimental and control groups.MAIN OUTCOME MEASURES: The detection rate of orthodontic enamel demineralization in the two groups alter the fixed orthodontic treatment.RESULTS: After evaluation of the results of both groups, the incidence rate of enamel demineralization in the experimental group (5.51%) was obviously lower than control group (15.1%).CONCLUSION: Fluor protector has a significantly positive effect on preventing enamel demineralizaUon dudng fixed orthodontic treatment.
