ABSTRACT
Purpose@#Intestinal Behcet’s disease (BD) is a systemic autoimmune disease for which treatment options are limited. As a prospective therapeutic strategy for intestinal BD, anti-tumor necrosis factor-alpha (anti-TNF-α) agents have received increasing attention. In this study, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety of anti-TNF-α agents for patients with intestinal BD. @*Materials and Methods@#We searched PubMed, Embase, and Cochrane Library databases up to July 1, 2021 and articles that met the eligibility criteria were further assessed. Pooled rates were synthesized by a randomized effects model using Stata software. @*Results@#Eleven clinical trials covering 671 patients with intestinal BD were included. According to compositive data, the pooled rate for remission was 39% [95% confidence interval (CI) 26–52] in patients receiving anti-TNF-α agents. Intestinal symptoms were cured in 70% (95% CI 53–84) of the patients, and the rate for endoscopic healing was 65% (95% CI 52–78). Corticosteroid discontinuation was achieved in 43% (95% CI 28–58) of the patients, and the dose reduction of corticosteroid was 20.43 mg (95% CI 13.4–27.46). There were 239 adverse events and 80 serious adverse events during follow-up. @*Conclusion@#Our study indicated that anti-TNF-α agents may serve as an effective treatment with acceptable safety for patients with intestinal BD. However, more robust evidence from randomized controlled trials is urgently needed to assess the long-term efficacy and safety of anti-TNF-α agents for those patients.
ABSTRACT
Objective:To investigate the effects of oxidized low density lipoprotein (Ox-LDL) on cell proliferation and mRNA expression of inflammatory factors in fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis (RA).Methods:Tissue culture was used to isolate and 4-6 generation cultured RA-FLS cells were used for subsequent experiments. RA-FLS were stimulated for 24 hours with different con-centr-ations of human Ox-LDL, then the MTS cell proliferation and toxicity test kit were used to detect the prolifer-ation of RA-FLS. Real time-polymerase chain reaction (RT-PCR) was used to test the expression of inflamm- atory factors like interleukin (IL)-6, transforming growth factor (TGF)-β, IL-8, tumor necrosis factor (TNF)-α and receptors like CD36 and scavenger receptor binds phosphatidylsed neoxidized lipoprotein (SR-PSOX) inRA-FLS. T test and F test were used in this study. Results:Ox-LDL (10, 25, 50 μg/ml) could obviously promote the proliferation of RA-FLS, and theabsorbance values (490 nm) were (1.04±0.15), (1.05±0.14), and (1.00±0.10), respectively, all higher than the control group (0.81±0.04) and the difference was statistically significant ( F=4.737, P<0.01). In addition, 50 μg/ml and 100 μg/ml Ox-LDL also promoted the expression of IL-6 mRNA ( F=14.709, P<0.01) and inhi-bited the expression of TGF-β mRNA ( F=299.074, P<0.01), but there was no obvious effect on the expression of IL-8 and TNF-α. Ox-LDL stimulation could obviously promote the expression of SR-PSOX receptor on RA-FLS ( F=68.636, P<0.01) and inhibit the expression of CD36( F=18.085, P<0.01). After the transfection of siRNA, SR-PSOX mRNA level was significantly inhibited and the mRNA expression of IL-6 was significantly decreased after Ox-LDL stimulation of RA-FLS ( t=3.875, P<0.01), while TGF-β mRNA expres-sion was not significantly changed( t=-0.193, P>0.05). Conclusion:Ox-LDL may play a role in promoting the activation of RA-FLS proliferation and the expression of IL-6 mRNA by increasing the SR-PSOX receptor of RA-FLS, suggesting that Ox-LDL is involved in the synovial inflammation of RA.
ABSTRACT
Objective:To analyze the clinical curative effect of protective sleep nursing on neonatal hyperbilirubinemia.Methods:Eight neonates with hyperbilirubinemia who were admitted from April 2019 to August 2019 were enrolled. They were divided into control group (40 cases) and observation group (40 cases) by random digits table method. Both groups were given routine nursing. On basis of control group, observation group was given protective sleep nursing. The clinical effect, sleep time, discomfort reactions and nursing satisfaction were compared between the two groups.Results:After nursing, the sleep time, crying time and bilirubin level were (18.67 ± 1.45) h/d, (0.82 ± 0.12) h/d, (191.58 ± 12.74) μmol/L in the observation group, and (17.63 ± 1.33) h/d, (1.05 ± 0.15) h/d, (202.42 ± 13.08) μmol/L in the control group, there were significant differences between the two groups ( t values were 3.343, 7.573, 3.755, P<0.05). The duration and regression time of jaundice were (5.26±1.24), (8.70±2.12) d in the observation group, and (7.14±1.18), (12.95±2.31) d in the control group, there were significant differences between the two groups ( t values were 6.946, 8.573, P<0.05). The good rate of sleep quality, incidence rates of vomiting, skin damage and needle falling out, and nursing satisfaction rate were 90.00%(36/40), 7.50%(3/40), 5.00%(2/40), 10.00%(4/40), 100.00%(40/40) in the observation group, and 72.50% (29/40), 27.50%(11/40), 22.50%(9/40), 32.50%(13/40), 87.50%(35/40) in the control group, there were significant differences between the two groups ( χ2 values were 4.021-6.050, P<0.05). Conclusions:The application of protective sleep nursing in treatment of neonatal hyperbilirubinemia can effectively prolong their sleep time, improve their sleep quality, which is conducive to improving their symptoms, reducing discomfort reactions.And satisfaction of their family members is relatively higher.
ABSTRACT
Objective To determine the mRNA levels of microRNA-223 (miR-223) and NLRP3 in-flammasome components [Nod-like receptor pyrin domain-containing protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC) and caspase-1] in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE) and to explore its clinical significance. Methods Real time polymerase chain reaction (PCR) was used to detect the mRNAlevels of miR-223 and NLRP3 inflam-masome components in PBMCs from 35 SLE patients, 30 healthy controls and 20 SLE patients after treatment, and then their correlations with clinical and laboratory parameters [anti-double-stranded deoxyribon-ucleic acid (dsDNA) antibody, anti-nucleosome antibody (AnuA), erythrocyte sedi-mentation rate (ESR)] were evaluated. Data were analyzed using t test or x2 test and Pearson test was used for correlation analysis. Results Com-pared with healthy controls, mRNA levels of miR-223 and Caspase-1 were higher in the PBMCs from SLE patients [(1.17 ±0.15) vs (0.68 ±0.14), t=2.416, P=0.0186; (1.89 ±0.13) vs (1.32 ±0.13), t=3.123, P=0.0027], but the NLRP3 and ASC mRNA expression levels were in the opposite [(0.64 ±0.05) vs (0.98 ±0.06), t=4.442, P<0.01;(0.98±0.08) vs (1.32±0.12), t=2.391, P=0.0198]. Correlation analysis results showed that there was a negative correlation of mRNA levels between the miR-223 and NLRP3 (r=-0.7849, P<0.05), but the miR-223 had no correlation with ASC and caspase-1. The mRNA levels of miR-223 was positively correlated with anti-dsDNA antibody, SLEDAI and ESR (r=0.7035, 0.6923, 0.6873, all P values<0.05), but had no correlation with AnuA. After treatment, the mRNA expression of miR-223 and caspase-1 in PBMCs from SLE patients was significantly reduced [(1.30±0.22) vs (0.79±0.11), t=2.07, P=0.0453; (2.05±0.19) vs (1.50±0.11), t=2.471, P=0.0183], while the mRNA level of NLRP3 increased [(0.69 ±0.08) vs (0.94 ±0.07); t=2.445, P=0.0193]. There was no significant difference in the expression of miR-223 mRNA in PBMCs between lupus nephritis (LN) patients and SLE patients without renal impairment. Conclusion miR-223 and caspase-1 are highly ex-pressed in the PBMCs from patients with SLE, while the mRNA of NLRP3 and ASC is in low expression. The mRNA expression of miR-223 is negatively correlated with NLRP3 and disease activity. Expression of miR-223 mRNA decreases significantly after treatment. So miR-223 may play an important role in the pathogenesis of SLE.
ABSTRACT
Fibrosis is the common pathological basis of various lesions. It is mainly manifested as excess collagen deposition and fibrous connective tissue in tissues with destructed structures and impaired function. At present, the pathogenesis of fibrosis is still unclear, and no effective treatment or prevention for fibrosis is available. In recent years, numerous studies have shown that chemokine CXCL16 and its receptor CXCR6 play an important role in the development of fibrosis. This paper summarizes the biological character-istics of CXCL16/CXCR6 axis and its role in fibrosis.
ABSTRACT
Objective:To explore diagnostic effects of 24h dynamic electrocardiogram (DCG) on pacemaker-induced rapid arrhythmias of different locations.Methods: Clinical data of 86 patients, who received pacemaker implantation in our hospital from Feb 2013 to Jan 2016, were retrospectively analyzed.According to ventricular electrode placement location, patients were divided into right ventricular septum (RVS) pacing group (RVS group, n=43) and right ventricular apex (RVA) pacing group (RVA group, n=43).The Tp-Te interval and occurrence of arrhythmias detected by 24h DCG were recorded and compared between two groups.Results: All patients received pacemaker implantation successfully, and pacemaker was fixed on RVS or RVA.There were no significant difference in pacing threshold, impedance and R wave amplitude between two groups, P>0.05 all.Compared with RVA group, there were significant reductions in Tp-Te intervals of V3 lead [(102.78±19.24)ms vs.(94.39±18.56)ms] and V4 lead [(96.39±13.11)ms vs.(85.87±14.59)ms] in RVS group (P=0.001 both).There were no significant difference in incidence rates of sinus arrest, II° sinoatrial block, atrioventricular block, atrial premature beats, transient paroxysmal atrial tachycardia and ventricular premature beats between two groups (P>0.05 all).Conclusion: The 24h DCG indicates that compared with RVA pacing, the Tp-Te interval of RVS pacing group significantly shorten, it may can better protect cardiac function.
ABSTRACT
Objective To determinate the serum level of adiponectin,visfatin and resistin in patients with rheumatoid arthritis (RA) and to explore its role in the development of RA and its clinical significance.Methods Blood samples were collected from 67 cases of RA patients and 65 healthy controls,the serum levels of adiponectin,visfatin and resistin were tested by enzyme linked immunosorbent assay (ELISA).Adipokine levels in different groups were compared using the Mann-Whitney U test.Spearman test and multivariate analysis were used to evaluate the correlation with clinical and laboratory parameters [erythrocyte sedimentation rate (ESR),C reactive protein (CRP),blood platelet (PLT),rheumatoid factor (RF),anti-cyclic citrullinated peptide (CCP),disease activity score (DAS)28].Results The serum level of adiponectin,visfatin and resistin in RA patients were significantly higher than those in healthy controls[8.17(4.51,28.53) μg/ml vs 6.83(4.48,25.32) μg/ml,U=1 663,P=0.019];[6.56(5.34,8.40) ng/L vs 4.24 (3.01,6.65) ng/L,U=762,P=0.001];[10.65 (5.99,20.70) ng/ml vs 6.12 (4.49,9.98) ng/ml,U=1 406.5,P=0.000].The serum level of visfatin was positively correlated with RF in patients with RA (r=0.186,P=0.013),and serum levels of adiponectin,visfatin and resistin were positively correlated with DAS28 (r=0.370,0.263,0.285;P＜0.05).The level of visfatin in RA patients with high activity group was higher than that in the low and moderate activity group [4.37(2.72,7.53)ng/L vs 4.11 (3.11,6.44) ng/L,U=133.5,P=0.019].Conclusion Multivariate analysis has showm that ESR,PLT and DAS28 can significantly affect adiponectin,and CRP can significantly influence resistin.Serum level of adiponectin,visfatin and resistin are elevated and correlate with DAS28,suggesting that they may be involved in the chronic inflammation of RA.
