ABSTRACT
Objective:To screen for circle RNA (circRNA) differentially expressed in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS), and to analyze its expression profile to explore the role of circRNAs in the pathogenesis of AS.Methods:CircRNA microarray chip technology was used to detect the expression of circRNAs in PBMCs of 3 patients with active AS, 3 patients with stable AS and 3 healthy controls (HC), and then screening for differentially expressed circRNAs by fold change (FC) and P value. Then differentially expressed circRNAs among the circRNAs with the highest differential expression were selected randomly to verify the chip results by real-time fluorescence quantitative polymerase chain reaction (qPCR); Differentially expressed circRNAs were subjected to Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and microRNA (miRNA) target prediction software was used to predict the circRNA/miRNA interaction relationship. Finally, the data were statistically analyzed by t test and Mann-Whitney U test. Results:① Chip text results showed that there were 800 circRNAs with significantly different expression (FC>1.5, P<0.05) in active AS than HC, of which 466 were up-regulated and 334 were down-regulated; the stable AS had a total of 1 149 significantly differentially expressed when compared with the HC (FC>1.5, P<0.05) circRNAs, of which 589 were up-regulated and 560 were down-regulated. 233 circRNAs were significantly differentially expressed (FC>1.5, P<0.05) between active AS and stable AS, of which 145 were up-regulated and 88 were down-regulated. ②The RT-qPCR verification results suggested that the expression trends of the four differentially expressed circRNAs were consistent with the results of the chip. ③ GO analysis results suggested that these differentially expressed circRNAs were mainly involved in nonsense-mediated mRNA decay, Rho GTPase binding and other processes. The analysis showed that the KEGG pathway were enriched in Th17 cell differentiation and chemokine signaling pathways. The results of miRNA target prediction software analysis suggested that differentially expressed circRNAs might play a role by targeting miR-650, let-7b-5p and other miRNAs. Conclusion:Compared with HC group, there were differentially expressed circRNAs in Peripheral Blood Mononuclear Cells (PBMCs) of AS patients, The results of this study suggest that these circRNAs may be involved in the pathogenesis of AS.
ABSTRACT
Objective:To analyze the expression of circular RNA (circRNA) in peripheral blood mononuclear cells (PBMCs) of patients with gout and to explore the possible mechanism of circRNA in the pathogenesis of gout.Methods:Peripheral blood samples of 24 patients with acute gout (AG), 24 patients with intermittent gout (IG) and 24 healthy control subjects (HC) were collected. Three cases of AG, IG, and HC were randomly selected, and the differentially expressed circRNA in PBMCs was screened by human circNA microarrays. The 6 circRNAs with large differences between the two comparison groups were selected, and the relative expression levels of 6 circRNAs in all the collected 72 PBMCs of the study subjects were detected by real-time fluorescent quantitative polymerase chain reaction (RT-qPCR). The significantly differentially ex-pressed circRNA (fold change>1.5, P<0.05) was analyzed by GO analysis, Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis, and its interaction with microRNA (miRNA) was predicted. The median (interquartile range) was used to describe the data, and the Mann-Whitney U test was used for comparison between groups. Results:(1) The microarray analysis results showed that compared with the HC group, the AG group and the IG group had 116 and 41 significantly differently expressed circRNAs, respectively; com-pared with the IG group, the AG group had 105 significantly differently expressed circRNAs. (2) Among the 6 circRNAs verified by PT-qPCR, the expression trends of 5 were consistent with the microarray results. The expression of hsa_circRNA_105034 in the AG group [5.17(4.60)] was statistically significantly different com-pared to the IG [1.68(2.39)] and HC [0.90(0.73)] groups (AG vs IG: Z=-4.413, P<0.01; AG vs HC Z=-5.052, P<0.01). (3) Bioinformatics analysis: ① GO analysis found that differential circRNA swere mainly involved in DNA transcriptional regulation, positive cell regulation and protein modification, etc. ② KEGG pathway analysis revealed that differential circRNA might be involved in the immune response mediated by the mitogen-activated protein kinase signaling pathway. ③ CircRNA might affect its inflammatory response by targeting molecules such as miRNA-146a, miRNA-302b and miRNA-23a. Conclusion:There are differentially expressed circRNAs in PBMCs of patients with gout, which may be closely related to the occurrence and development of gout.
ABSTRACT
Objective:To investigate the clinical features, laboratory characteristics and risk factors of systemic sclerosis (SSc) patients with hematologic damages.Methods:The clinical data of 180 SSc patients were collected from January 2010 to April 2020, at the Affiliated Hospital of North Sichuan Medical College. The demographic information, laboratory tests, and clinical symptoms were analyzed retrospectively. Statistical Product and Service Solutions (SPSS) 19.0 was used for t-test, non-parametric Mann-Whitney U test, Chi-squared test, Logistics regression analysis. Results:① Among 180 SSc patients, 70(38.9%) cases were complicated with hematologic damages. Fifty-one (72.9%) cases had anemia, 24 cases (34.3%) had leukopenia, 24 cases (34.3%) had thrombocytopenia, and 22 cases had hematologic damages associated with more than two cell line involvement. ② Clinical symptoms: arthritis was significantly higher in the hematologic damage group than patients without( χ2=4.815, P=0.028), however, there was no significant difference in gender, age, disease course, respiratory symptoms, gastrointestinal symptoms, Raynaud's phenomenon, interstitial lung disease and pulmonary hypertension ( P>0.05). ③ Laboratory tests: erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) were increased in the hematologic damage group, while the albumin decreased ( Z=-2.448, P=0.014; Z=-2.450, P=0.014; Z=-4.773, P<0.01). The positive rates of anti-dsDNA antibody and anti-ribosomal P protein anti-body was higher in the hematologic damage group ( χ2=5.428, P=0.020; χ2=8.169, P=0.004). ④ Prognosis: during follow-up, leukopenia was more likely to recover, while the thrombocytopenia was more difficult to recover. ⑤ Logistics regression analysis showed that positive of anti-ribosomal P protein antibody might bea risk factor for SSc complicated with hematologic damages [ OR=3.930, 95% CI(1.130, 13.666, P=0.031)]. Conclusion:SSc complicated with hematologic damages is common, and patients with hematological damage have more serious clinical symptoms, some of whom have difficulty in recovery. Anti-ribosomal P protein anti-body may be a risk factor for SSc hematologic damages.

ABSTRACT
OBJECTIVE@#To explore the clinical features and treatments of contact granuloma of larynx.@*METHOD@#To find the best treatments by analyzing the clinical features, related causes and the treatments of the 13 contact granuloma of larynx cases, which have complete data, of our department from Jan 2005 to Dec 2012, also by comparing the effect of conservative treatment and operation treatment.@*RESULT@#Contact granuloma of larynx is more common in men (84.6%). The main causes are gastro esophageal reflux, chronic cough, habitual hawk and endotracheal intubation disease. However, a big part (38.4%) gets the disease without any other disease history. The main clinical feature of the disease includes: sensation of foreign matter in throat, easy to get exhausted when talking and voice hoarse, but also 30.7% without any feature in throat. Among the 13 cases, 6 were treated by operation and the first recurrence was 66.6%. The cure rate was 50% after one or two operations. The other 7 were treated in conservative way, including anti- Gastro esophageal reflux, avoiding excessive talking, reducing habitual hawk ,or without any medical treatment. The cure rate was 57.1%. The total cure rate was 53.8%. However, it is nonsense to comparing the two different treatments (Chi2 = 0.066, P > 0.05).@*CONCLUSION@#There is still no standard treatment for contact granuloma of larynx and the effect is not good enough. The treatment should be depending on individual case. Conservative treatment is the first choice. However, operation should be considered if the patient has obviously hoarse and his granuloma is too large to breathe well.

AIM To study the effect of genistein (GST), a protein tyrosine kinases inhibitor, on L-type calcium channel currents (Iba,L or Ica,L, dependent on permeating ion used) in freshly dispersed colon smooth muscle cells from guinea-pig. METHODS Single colon smooth muscle cells were enzymatically dissociated from guinea-pig. L-type calcium currents were measured by conventional whole-cell patch-clamp techniques. RESULTS The peak amplitudes of Iba,L elicited to 10 mV test potential from a holding potential of -80 mV, were reversibly and dose-dependently reduced by GST (10-100 μmol·L-1) with an IC50 value of (39.9±3.6)μmol·L-1. Bath application of GST shifted the steady-state inactivation curves of Iba,L in a hyperpolarized direction (about 10 mV, P＜0.01) without altering their slopes. The peak amplitudes of Iba,L were also inhibited but to a less extent by daidzein, an inactive analogue of GST. Sodium orthovanadate 1 mmol·L-1, a potent inhibitor of protein tyrosine phosphatases, blocked GST-induced inhibition of Ica,L. CONCLUSION GST can block L-type calcium channel activity in guinea-pig colon smooth muscle cells via tyrosine kinase pathway.
