Objective To study the expression level of NLRP3 (NLR family, pyrin domain containing3) inflammasome (NLRP3, ASC, caspase-1 ) mRNA in peripheral blood monocytes (PBMCs) from patients with gout arthritis (GA) and to explore the pathogenesis of GA. Methods NLRP3 inflammasome mRNA was measured using quantitative real-time PCR in PBMCs. The expression of NLRP3 inflammasome mRNA in PBMCs was compared between patients with GA (n=24) and healthy controls (n=24). β-actin was selected as the internal control. Students' t-test was used in two independent samples and Spearman's correlation was used to evaluate the relationship between mRNA level and inflammatory parameters. Results The expression of ASC mRNA in GA increased significantly when compared to healthy controls [(0.029±0.021 ) vs (0.009±0.007 ), P<0.01 ], and the expression of NLRP3 and caspase-1 mRNA was significantly lower in patients with GA compared to healthy controls [(0.062±0.084) vs (0.133±0.106), P<0.05; (0.025±0.014) vs (0.117±0.156), P<0.01]. Moreover, the expression of ASC mRNA was found to correlate significantly with globulin (r=-0.547, P<0.05) and very low density lipoprotein cholesterol (r=-0.540, P<0.05) in GA patients,and caspase-1 was correlated to globulin(r= -0.773. P<0.01) and very low density lipoprotein cholesterol (r=-0.465. P<0.05). Furthermore, the ASC mRNA in GA patients was associated significantly with NLRP3 mRNA(r=-0.450, P<0.05) and caspase-1 (r=0.604, P<0.01 ). Conclusion Dysregulated expression of the NLRP3inflammasome is involved in the inflammatory response and plays a key role in the pathogenesis of GA.

Objective To explore the anti-tumor effects of Egr-IFNγ gene therapy combined with 125I-UdR radionuclide therapy in mice bearing H22 hepatocarcinoma and its mechanism. Methods The recombinant plasmid pcDNAEgr-IFNγ mixed with liposome was injected into tumor. 48 h later, 370 kBq 125I-UdR was injected into tumor. The tumor growth rates at different times were observed. After 3 d gene-radionuclide therapy, the concentration of IFNγ in cytoplasm of H22 cells and cytotoxic activities of splenic CTL of the mice in different groups were examined. Results The tumor growth rates of pcDNAEgr-IFNγ +125 I-UdR group were obviously lower than those of control group, 125I-UdR group and pcDNAEgr-1 +125I-UdR group 6-15 d after gene-radionuclide therapy. IFNγ protein was found in cytoplasm of H22 cells in PcDNAEgr-1FNγ+125I-UdR group after 3 d gene-radionuclide therapy. Cytotoxic activity of splenic CTL in pcDNAEgr-IFN7 + 125I-UdR group was significantly higher than that in the other groups (P<0.01). Conclusions The anti-tumor effects in vivo of pcDNAEgr-IFNγ gene therapy combined with 125I-UdR radionuclide therapy are better than those of 125I-UdR therapy.

Objective To investigate the single nucleotide polymorphisms(SNPs) rs3733591(C>T) of SLC2A9 gene in Chinese Han population, and to explore the association of this gene polymorphisms with gout susceptibility, tophi, serum uric acid levels, other clinical and laboratory data and the levels of SLC2A9 mRNA of peripheral blood mononuclear cells(PBMCs). Methods ① A total of 297 primary gout arthritis patients(GA) and 211 normal controls(NC) were enrolled into this study. The clinical and laboratory data of patients were collected. The genotypes and alleles frequencies were measured by using TaqMan ?SNP Geno-typing Assays and the possible association between gene polymorphism of SLC2A9 and gout was investigated by Chi-square test. The odds ratios(OR) and 95% confidence intervals(95%CI) were calculated. ② The lev-els of SLC2A9 mRNA on PBMCs of 86 gout patients(46 patients in remission) and controls were measured by real-time quantitative polymerase chain reaction (RT-qPCR). The nonparametric test was used to analyze the expression in different groups. Results The frequencies of genotypes and alleles of rs3733591(C>T) in gout patients were different from controls(P<0.05). The frequency of TT genotype was significantly lower than that in controls (P<0.05) and the relative risk of this genotype to develop gout was 0.647 (95%CI: 0.452-0.925). Moreover, the frequency of T allele in cases was much lower than in controls (60.9% vs 69.2%, χ2=7.324, P=0.007, OR=0.695), but the frequency of C allele was much higher(39.1% vs 30.8%, χ2=1.440, P=0.007, OR=1.440). Interestingly, the levels of SLC2A9 mRNA on PBMCs in gout patients who carried TC genotype of rs3733591 was higher than those who carried TT genotype(P<0.05). There was no difference in the expression of SLC2A9 mRNA on PBMCs among different genotype carriers of rs3733591 in controls (P>0.05). However, there was no significant difference in the distribution of genotypes and alleles between 30 tophaceous gout patients and 190 non-tophaceous gout patients(P>0.05). Conclusion Results of present study suggest the rs3733591(C>T) polymorphism of the SLC2A9 gene might be associated with gout development, but not with tophaceous gout. The C allele predisposes to gout, and TT genotype and T allele might protect Chinese Han population from developing gout. The rs3733591(C>T) polymorphism probably affects the susceptibility to gout by influencing the f expression of SLC2A9 mRNA susceptibility.

Objective This study is aimed to evaluate the association between the ABCG2 gene rs2231142 variant and gout using meta-analysis. Methods Related studies were identified by searching extensively in Chinese and foreign language databases such as Pubmed, EMBASE, Cochrane Library, CBMdisc databases and so on. The quality of included studies was assessed by using the Newcastle-Ottawa Scale (NOS). The odds ratio (OR) was calculated using a random-effects or fixed-effects model. A Q statistic was used to evaluate the heterogeneity, and Eggerˊs test and funnel plot were used to assess publication bias. Sub-group analyses on ethnicities and sex were also performed. Results A total of 10 studies, including 3 478 gout patients and 10,089 controls from 6 countries or regions, were included and identified for the current metaan-alysis. It was found that the A allele or AA genotype of the ABCG2 rs2231142 polymorphism had an increased risk for gout in the general population [A allele: OR=2.03, 95%CI (1.77, 2.34), P<0.01 and AA genotype: OR=3.01, 95%CI (2.34, 3.88), P<0.01, respectively]. Similar results were found in sub-group analyses of different gender and races. Conclusion Existing evidence indicate that rs2231142 polymorphism (the A allele and AA genotype) is associated with increased risk of gout.

Objective To investigate the application of Follow-up System in health management for the patients after percutaneous coronary intervention (PCI). Methods 100 patients underwent PCI were divided into study group (n=50) and control group (n=50). The control group received routine follow-up and the study group was followed up with the direction of Follow-up System. The incidence of adherence to medication after discharge and awareness of risks of coronary heart disease were recorded 6 and 12 months after discharge. Results The incidence of adherence to medication decreased in the control group (P<0.05) after discharge, but was stable in the study group (P>0.05). Awareness of risks of coronary heart disease increased in the study group 12 months after discharge (P<0.01), but was stable in the control group (P>0.05). Conclusion Follow-up System may help to improve the compliance and awareness in health management in the patients after PCI.
