The long noncoding RNAs refers to RNA transcripts more than 200 nucleotides in length,and do not encode proteins.In the end of the 20th century,the lncRNAs were found to play crucial role in many important biological processes,including embryonic development,cell differentiation,species evolution,metabolism,and disease occurrence by the scientific community.Currently,multiple studies have indicated that long noncoding RNAs have participated in rheumatic diseases,immune response,immune cell differentiation,and dynamic balance of the immune system.Therefore,summary of the roles of lncRNAs in rheumatic diseases could be beneficial to understand the pathogenesis of autoimmune diseases.This review article attempts to highlight the recent progresses regarding IncRNAs studies and the relationship between long noncoding RNA and rheumatic diseases by taking systemic lupus erythematosus,rheumatoid arthritis,arthritis and other typical diseases as examples.

Objective To explore the characteristics of hematological changes in patients with primary Sj(o)gren'syndrome (pSS).Methods The clinical data of 49 cases with pSS were retrospectively analyzed.Resuits The data showed that 25 patients (51%) among 49 cases had hematological changes.of which 15 cases were anaemia (31%).8(16%) were leukopenia,and 10 cases (20%) were thrombocytopenia.And 6 cases had two cell lines involved.2 cases had three cell lines involved.Twenty-three bone marrow aspirations revealed active proliferation or normal cell proliferation and the morphology of all 3 cells lines were normal.Bone marrow examination had strong positive iton stain and 15 cases with anaemia showed positive iron stain.Seven out of 10 patients with thrombocytopenia had megakaryocyte maturation defect.Conclusion Hemotologieal changes are common.and anemia is the most common findings.Cytopenia is related to autoantibodies mediated stem cell damages.but anemia iS caused by iron metabolic disturbance.while thrombocytopenia is generally due to functional impairment of megakaryocytes.

Objective To explore the role of interleukin (IL)-1β in the pathogenesis of gout.Methods Real-time quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay(ELISA) were used to measure the expression of IL-1β mRNA in peripheral blood mononuclear cells (PBMCs) and IL-1β in plasma samples from 120 acute gouty (AG) arthritis,70 chronic gouty (CG) arthritis,80 intercritical gouty (IG) arthritis patients and 96 healthy control subjects respectively.Results The expression of PBMCs IL-1β mRNA and plasma concentration of IL-1β were both much higher in gout patients than those in controls (P ＜ 0.01,respectively).And the plasma levels of IL-1β mRNA and IL-1β significantly increased in the AG group compared with CG and IG groups (P ＜ 0.01,respectively) and much higher in the CG group than those in the IG group.Positive correlations existed between plasma concentration of IL-1β and the levels of white blood cell,neutrophil,monocyte,erythrocyte sedimentation rate,blood uric acid,globulin and PBMCs IL-1β mRNA (P ＜ 0.01,respectively) while negative correlation between plasma IL-1β and plasma level of apolipoprotein in gout patients (P ＜ 0.05).Conclusion Elevated plasma level of IL-1β may be involved in the pathogenesis of acute and chronic gouty arthritis.

Objective To study the inner diameter and hemodynamics of ophthalmic artery(OA)and central retinal artery(CRA)in hyperuricemia by Enhance-flow(eFlow)imaging and spectral Doppler.Methods One hundred and one patients with hyperuricemia and 30 volunteers were selected,the inner diameter in eFlow imaging and the peak systolic velocities(PSV),the end diastolic velocities(EDV),the resistive index(RI)were measured,and pulsatility index(PI)of OA and CRA were measured by spectral Doppler.The 101 patients were divided into two groups according to the time of diagnosing hyperuricemia,one group had a diagnosis of hyperuricemia for more than five years and the other had such a diagnosis for less than five years.The data were compared by t-test.Then,the patients were further divided into a group of hyperuricemia combined with hypertension and the other without hypertension.The differences between the experimental group and the group of volunteers were carried out by One-way ANOVA,the comparison between two groups were analyzed with SNK.Results The RI(0.68±0.09)and PI(1.3±0.4)of OA in patients who were diagnosed as hyperuricemia for more than 5 years was higher[RI:0.63±0.09,PI:1.1±0.3(t=3.504,P=0.001 ;t=3.164,P=0.002)],the EDV[(6±3)cm/s]of OA was lower than those patients with a diagnosis of hyperuricemia for less than 5 years[(8±5)cm/s,t=1.988,P=0.049].The PSV[(11.5±3.5)cm/s]and EDV[(3.7±1.1)cm/s]of CRA in hyperuricemia combination hypertension group was lower,and the RI (0.88±1.40)was higher than hyperuricemia without hypertension group[PSV:(13.5±4.0)cm/s,EDV:(4.1±1.2)cm/s,RI:0.67±0.08].Conclusion By eFlow and spectral Doppler,we have found that hyperu-ricemia could accelerate OA and CRA atherosclerosis.The eFlow and spectral Doppler are valuable methods to study the hemodynamics in ophthalmic artery of patients with hyperuricemia.

Objective:To explore the expression and clinical significance of late autophagy in per-ipheral blood mononuclear cells (PBMCs) of patients with primary gouty arthritis (GA).Methods:Peripheral blood, clinical data, and laboratory tests were collected from 30 patients with acute gout (AG), 30 patients with intermittent gout (IG), and 50 healthy controls (HC). Quantitative polymerase chain reaction (RT-qPCR) was used to detect mRNA expression levels of autophagy-related genes (ATG5, ATG12, ATG16, ATG3, ATG7, ATG10, ATG4B, LC3-2/LC3B). Measurement data conformed to normal distribution were tested using t test or analysis of variance (ANOVA), and non-normal distribution data were tested using Mann-Whitney test or Kruskal-Wallis H test. SNK was used for pairwise comparison among the three groups. Correlation between variables was tested by Spearman correlation analysis. Results:① The expression level of ATG5 mRNA,ATG12 mRNA, ATG16 mRNA, ATG10 mRNA and LC3-2 mRNA in the AG group was lower than that of the IG group and the HC group, and the expression level of the IG group was lower than that of the HC group[9.16×10 -3(6.04×10 -3, 15.00×10 -3) vs 14.48×10 -3(9.95×10 -3, 21.38×10 -3) vs 0.08×10 -3(12.21×10 -3, 42.79×10 -3), H=19.377, P<0.001; 18.89×10 -3(13.85×10 -3, 24.92×10 -3) vs 21.13×10 -3(12.11×10 -3, 28.06×10 -3) vs 33.57×10 -3(13.11×10 -3, 49.89×10 -3), H=7.545, P=0.023; 8.72×10 -3(4.96×10 -3, 13.74×10 -3) vs 10.62×10 -3(7.48×10 -3, 24.71×10 -3) vs 20.07×10 -3(11.99×10 -3, 39.56×10 -3), H=20.962, P<0.001; 1.05×10 -3(0.73×10 -3, 1.84×10 -3) vs 1.60×10 -3(0.93×10 -3, 2.58×10 -3) vs 1.69×10 -3(1.05×10 -3, 3.54×10 -3), H=8.193, P=0.017; 2.31×10 -3(1.22×10 -3, 3.53×10 -3) vs 2.78×10 -3(1.68×10 -3, 5.96×10 -3) vs 3.68×10 -3(2.00×10 -3, 5.67×10 -3) , H=7.135, P=0.028]. The expression level of ATG4B mRNA in the AG and IG group was higher than that in HC group, and there was significant difference between IG group and AG group, IG group and HC group[9.95×10 -3(6.32×10 -3, 12.23×10 -3) vs 10.86×10 -3 (8.80×10 -3, 17.03×10 -3) vs 8.07×10 -3(5.52×10 -3, 11.63×10 -3), H=8.531, P=0.014]. There was no significant difference between the ATG3 mRNA and ATG7 mRNA groups ( H=0.539, 3.739, bothall P values >0.05). ② The results of Spearman correlation analysis suggested that in patients with acute gout, ATG3 was negatively correlated with PDW and MPV ( r=-0.499, P=0.006; r=-0.463, P=0.011); ATG4B was positively correlated with HDL-C ( r=0.408, P=0.048); ATG7 was negatively correlated with GLOB ( r=-0.554, P=0.001); ATG10 was positively correlated with ALB ( r=0.412, P=0.024) and negatively correlated with Crea and hsCRP ( r=-0.459, P=0.011; r=-0.375, P=0.045); ATG12 was negatively correlated with MO ( r=-0.434, P=0.017); ATG16 was negatively correlated with ALT and AST ( r=-0.389, P=0.034; r=-0.366, P=0.047); LC3-2 was positively correlated with UA ( r=0.381, P=0.041) and negatively correlated with MPV and PDW ( r=-0.413, P=0.026; r=-0.449, P=0.015). In patients with intermittent gout, ATG3 and ATG4B were negatively correlated with apoB100 ( r=-0.555, P=0.011; r=-0.462, P=0.040); ATG5 was negatively correlated with Crea ( r=-0.456, P=0.011); ATG10 was negatively correlated with TC, LDL-C, and apoB100 ( r=-0.526, P=0.017; r=-0.556, P=0.011; r=-0.515, P=0.020). Conclusion:Autophagy is involved in the development of gout, and is correlated with ibflammatory and metabolic indicators, suggesting that autophagy is an important feature in the pathogenesis of GA.

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 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 investigate the effects of lipoxin A4 ( LXA4 ) on inflammatory related factors induced by uric acid( UA) in human umbilical vein endothelial cells( HUVECs) . Methods HUVECs were treated with 5, 25, and 50 ng/ml LXA4 prior to exposure to 12 mg/dl UA. Tumor necrosis factor-alpha(TNF-α), interleukin ( IL)-1β, and IL-6 were analyzed with ELISA and realtime PCR. The phosphorylation levels of p38 mitogen-activated protein kinases( MAPK) and NF-κB/p65 were observed with Western blot. Results Stimulation of HUVECs with 12 mg/dl UA markedly increased TNF-α, IL-1β, and IL-6 production(P<0. 01). Pretreatment with LXA4 significantly inhibited UA-induced production of TNF-α, IL-1β, and IL-6 in a concentration dependent manner(P<0. 01). The mRNA expressions of TNF-α, IL-1β, and IL-6 in response to UA were also decreased by LXA4(P<0. 05). Western blot analysis showed that the phosphorylation levels of p38 MAPK and NF-κB/p65 were significantly raised by 12 mg/dl UA in HUVECs(P<0. 05), but attenuated significantly in the presence of 50 ng/ml LXA4. Conclusion LXA4 may inhibit the expressions of inflammatory related factors induced by UA via reducing p38 MAPK and NF-κB/p65 phosphorylation and play a role in anti-inflammation.
