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 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 investigate the role of adiponectin (ADP) and its receptors (ADR) in pati ents with primary gouty arthritis (GA).Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of plasma ADP in 88 GA and 80 healthy controls (NC).Real time quantitative polymerase chain reaction (RT-qPCR) was employed to study the expression of ADR1 and ADR2 mRNA in peripheral blood mononuclear cells (PBMCs).The biochemical indicator of TG,HDL,LDL,VLDL,apoA1,apoB100 and uric acid (UA) were detected at the same time.T test,Spearman's correlations and regression analysis were used for statistical analysis.Results The concentration of plasma ADP was significantly lower in GA than that in NC [(6±7) μg/ml,(8±6) μg/ml,t=-3.71,P＜0.01 ],the expression of ADR1 and ADR2 mRNA in GA (ADR1:0.09±0.08,ADR2:0.0122±0.0164) was significantly increased when compared to the NC (ADR1:0.05±0.03,ADR2:0.0054±0.0024) (t=2.71,2.35,P＜0.05).In the GA patients,the level of ADP was negatively correlated with the lymphocytes count (LY) and UA (r=-0.32,-0.36,P＜0.05),and it was positively correlated with ESR and LDL level (r=0.31,0.39,P＜0.05).The expression of ADR1 mRNAwas negatively correlated with TG (r=-0.43,P＜0.05 ),but positivdy correlated with ESR and CRP level (r=0.45,0.57,P＜0.05).The expression of ADR2 mRNA was negatively correlated with glucose and UA(r=-0.50,-0.59,P＜0.05).Conclusion Altered expression of ADP and its receptors may be involved in thepathogenesis of gouty inflammation.

objective The roles of TLRs and their signal pathway in gouty arthritis(GA)were explored.Methods TLR2 and TLR4 mRNA was measured using real-time quantitative polymerase chain reaction(RT-PCR)in PBMCs,IL-1β level was detected using ELISA in plasma,and NF-κB p65 protein level in PBMCs was measured using Western blot.Level of TLR2 mRNA,ILR4 mRNA,IL-1β,NF-κB p65protein was compared among acute GA,non-acute GA and healthy controls.Correlation between TLR2mRNA,TLR4 mRNA and serum uric acid,IL-1β level in GA patients was analyzed.One-way ANOVA was used to analyze data between multiple groups and q-test was used for two-two comparison.Spearman's analysis was applied for correlation analysis.Resuits The expression of TLR4 mRNA,NF-KB p65 protein,IL-1β arid serum uric acid level in patients with acute GA [(5.0±1.2), (7.11±0.18), (283±83)pg/ml,[585±123)μmol/L] was significantly increased compared to non-acute GA[(2.3±0.4),(0.63±0.06),(134±29)pg/ml,(493±107)μmol/Lj and healthy controls(1.1±0.6),(0.52±0.12),(97±17)pg/ml,(326±65)μmol/L](P<0.01,respectively).Significant diffefence was also observed between non-acute GA patients and healthy controls(P<0.05,respectively).The level of TLRR4 mRNA was positively correlated with uric acid and IL-1β level in GA patients(rs=0.876,0.779;P<0.05,respectively).Conclusion Innate immunity are activated by membrane-type pattern recognition receptors in primary GA.TLR4-NFκB p65-IL-1β signat transduction may participate in the inflammatory mechanisms of gout.Urate crystals in patients with gout may:be involved in the activation of TLR4 and its signal pathway.

Objective To investigate the expression levels of telomeric protein TPP1 and POT1mRNA in the peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE), and the relations between these gene expression levels and disease activity are explored. Methods TPP1 and POT1 genes were measured using real-time polymerase chain reaction (RT-PCR) in PBMCs. The expression levels of TPP1 and POT1 genes in PBMCs were compared between 48 SLE patients and 30 healthy indivi-duals. Results The expression levels of TPP1 and POT1 in the PBMCs of SLE patients significantly decreased compared to healthy individuals (P<0.01). The expression levels of TPP1 and POT1 were much lower in SLE patients with lupus nephritis than those in patients without lupus nephritis (P<0.01), and in LN patients, the levels of TPP1 and POT1 were negatively correlated with proteinuria. The expression levels of POT1 in active SLE patients was lower than that in inactive SLE patients (P<0.05). The expression levels of POT1 was negatively correlated with serum IgG and SLEDAI scores, but positively correlated with complement C3, but no correlation between ESR, CRP, C4,ANA and the expression levels of TPP1, POT1, SLEDAI scores. Conclusion TPP1 and POT1 genes play a key role in the etiology of SLE, and they are involved in the pathogenesis of lupus nephritis. POT1 is helpful in evaluating SLE disease activity and severity.
