RESUMEN
Abstract This study aimed to determine salivary concentrations of interleukin (IL)-1β, IL-2, IL-10, IL- 23, transforming growth factor (TGF)-β, tumor necrosis factor (TNF)-α, nitrate (a by-product of nitric oxide oxidation), and cortisol in patients with oral lichen planus (OLP). Twenty patients diagnosed with OLP and 20 sex-matched healthy volunteers (HV) were included in this cross-sectional study. Unstimulated whole saliva was collected in the morning. Salivary cytokine and cortisol concentrations were determined by enzyme-linked immunosorbent assays (ELISA). Nitrate was measured in a nitric oxide analyzer. We found higher salivary concentrations of IL-2 (p<0.003), IL-23 ( p<0.04), and TGF-β (p=0.05) in patients with OLP compared to HV. No significant differences were found in salivary levels of TNF-α, IL-1β, or IL-10. Nitrate concentrations were markedly increased in OLP patients (1,227.0 ± 738.8 µM/mg total protein) when compared to HV (261.6 ± 166.8 µM/mg; p<0.0001). Salivary cortisol levels were also higher in OLP patients (2.79 ± 1.39 vs. 1.94 ±1.21 ng/mg; p<0.048). The markedly increased salivary levels of nitric oxide in patients with OLP suggest a relationship of this molecule with the cell death and tissue damage observed in these lesions.
Resumen Este estudio tuvo como objetivo determinar las concentraciones salivales de interleucina (IL)-1β, IL-2, IL-10, IL-23, factor de crecimiento transformante (TGF)-β y factor de necrosis tumoral (TNF)-α, nitrato (subproducto de la oxidación del óxido nítrico) y cortisol en pacientes con liquen plano oral (OLP). En este estudio transversal se incluyeron veinte pacientes diagnosticados con OLP y 20 voluntarios sanos (HV) del mismo sexo. Saliva entera no estimulada Se recolectó por la mañana, se determinaron las concentraciones de citocinas y cortisol en saliva mediante ensayo inmunoabsorbente ligado a enzimas (ELISA), se determinó nitrato mediante un analizador de óxido nítrico, se encontraron concentraciones salivales mayores de IL-2 (p<0,003), IL- 23 (p<0,04) y TGF-β (p=0,05) en pacientes con OLP en comparación con HV. No se encontraron diferencias significativas en los niveles salivales de TNF-α, IL-1β e IL-10. Las concentraciones de nitrato fueron marcadamente aumentó en pacientes con OLP (1227,0 ± 738,8 µM/mg de proteína total), en comparación con HV (261,6 ± 166,8 µM/mg; p<0,0001). Los niveles de cortisol salival también fueron más altos en los pacientes con OLP que en los controles (2,79 ± 1,39 vs. 1,94 ±1,21 ng/mg; p<0,048). Los niveles de óxido nítrico en saliva aumentaron notablemente en pacientes con OLP, lo que sugiere una relación de esta molécula con la muerte celular y el daño tisular observado en las lesiones de OLP.
RESUMEN
Background: Lung cancer patients are at high risk for depression, which is associated with poor treatment adherence. Medical hypnosis can improve symptoms of depression and affect interleukin-6 levels. This study aims to determine the effectiveness of medical hypnosis in improving depression and reducing IL-6 levels in lung cancer patients. Methods: This study is a quasi-experimental study with a pretest and post-test control group design. It assessed depressive symptoms using BDI-II scores and serum IL-6 levels in an intervention group receiving medical hypnosis and standard therapy compared to a control group receiving standard therapy. Data analysis was conducted using univariate tests, followed by Pearson correlation tests and effect size measurement with Cohen's d test. Results: The Wilcoxon test showed a decrease in IL-6 levels in the intervention group by 14.66�.45 (p=0.008) and a reduction in BDI-II scores by 8.26�78 (p=0.001). Correlation tests indicated a significant relationship between IL-6 levels and BDI-II scores (r=0.472; p=0.009). Cohen's d test showed the effect size of medical hypnosis on IL-6 levels was 0.754 (moderate=0.5<ES<0.8). Conclusions: Medical hypnosis is effective in improving depressive symptoms and reducing IL-6 levels in lung cancer patients.
RESUMEN
Abstract Objectives: This paper aims to review data on the association of obesity and iron deficiency in children and adolescents, exposing the possible involvement of hepcidin and interleukin-6 (IL-6), obesity's inflammation biomarkers. Data source: Articles from PUBMED and WEB OF SCIENCE database with no chronological limit were reviewed to write this systematic review. Keywords such as children, obesity, iron deficiency, and hepcidin were used. After deleting duplicated and review articles, 91 were screened, and 39 were selected as eligible. Sixteen articles were included because they involved serum hepcidin levels in obese children and adolescents as outcomes. Summary of findings: Finally, those 16 articles were organized in two tables: one includes therapeutic interventions, and the other does not. As hepcidin was discovered in 2000, the first articles that presented serum hepcidin's quantification in obese children and adolescents, homeostasis iron markers, and their possible association with obesity's inflammatory environment began to be published in 2008. Conclusions: Obesity's chronic inflammation state leads to the production of IL-6, which acts as a signaling molecule for hepcidin synthesis, resulting in iron deficiency, which is common in obese children and adolescents who respond inadequately to iron supplementation. On the other hand, that population responds adequately to therapeutic intervention programs that lead to weight loss, guaranteeing iron homeostasis improvement. Therefore, perhaps it is time to discuss serum hepcidin level quantification as part of evaluating children and adolescents with iron deficiency, which could guide clinical choices that might lead to better therapeutic outcomes.
RESUMEN
Abstract Introduction: This publication aims to show the clinical, endoscopic, and histological responses of two pediatric patients who received dupilumab as a management strategy for eosinophilic esophagitis. Dupilumab is a monoclonal antibody that inhibits the alpha chain of the interleukin (IL)-4 and IL-13 receptors involved in the Th2 inflammatory response. The potential therapeutic role of this biological drug has been demonstrated in pediatric clinical trials in other allergic pathologies, such as atopic dermatitis and asthma, with an adequate safety and effectiveness profile. Clinical cases: Two children with a personal history of atopy, allergic rhinitis, asthma, atopic dermatitis, and food allergy began with gastrointestinal symptoms that confirmed the diagnosis of eosinophilic esophagitis. Despite the different management strategies, adequate control of the disease was not achieved, and it is considered that they benefited from management with dupilumab due to the disease evolution and the coexistence of uncontrolled atopic dermatitis. Conclusions: In recent years, various management strategies in pediatrics have been published, particularly high-dose proton pump inhibitors, topical corticosteroids, and elimination diets. However, despite these strategies, at least one-third of patients may fail to achieve remission with initial treatment, making this entity a therapeutic challenge for the gastroenterologist and pediatric allergist. Our patients received the dose recommended for their weight and age and approved for asthma and atopic dermatitis, resulting in clinical and histological remission. The improvement in gastrointestinal symptoms was accompanied by better control of asthma, rhinitis, and dermatitis. None of the patients had adverse effects of the medication.
Resumen Introducción: El objetivo de esta publicación es mostrar la respuesta clínica, endoscópica e histológica de dos pacientes pediátricos que recibieron dupilumab como estrategia de manejo para esofagitis eosinofílica. El dupilumab es un anticuerpo monoclonal que inhibe la cadena alfa del receptor de las interleucinas 4 y 13, involucradas en la respuesta inflamatoria Th2. El potencial rol terapéutico de este medicamento biológico se ha demostrado en ensayos clínicos en pediatría en otras patologías alérgicas como la dermatitis atópica y el asma, y ha mostrado un adecuado perfil de seguridad y efectividad en pediatría. Casos clínicos: Se trata de dos niños con antecedentes personales de atopia, rinitis alérgica, asma, dermatitis atópica y alergia alimentaria, que inician con síntomas gastrointestinales que conducen a confirmar el diagnóstico de esofagitis eosinofílica, en quienes a pesar de las diferentes estrategias de manejo no se logra un adecuado control de la enfermedad, y se considera que se benefician del manejo con dupilumab por la evolución de la enfermedad, así como la coexistencia de dermatitis atópica no controlada. Conclusiones: En los últimos años se han publicado diferentes estrategias de manejo en pediatría, entre los que se destaca el uso de inhibidores de la bomba de protones a dosis altas, corticoides tópicos y las dietas de exclusión; sin embargo, a pesar de estas estrategias, al menos un tercio de los pacientes puede fallar en lograr la remisión con el manejo inicial, lo que convierte a esta entidad en un reto terapéutico para el gastroenterólogo y el alergólogo pediatra. Nuestros pacientes recibieron la dosis recomendada para su peso y edad aprobada en asma y dermatitis atópica, y se logró la remisión clínica e histológica. La mejoría de los síntomas gastrointestinales se acompañó de un mejor control del asma, la rinitis y la dermatitis. Ninguno de los pacientes tuvo efectos adversos al medicamento.
RESUMEN
Abstract Background: Only a fraction of patients with cutaneous lupus erythematosus (CLE) will eventually progress toward systemic disease (SLE). Objective: To find inflammatory biomarkers which could predict the progression of cutaneous lupus erythematosus (CLE) into systemic lupus erythematosus (SLE) using immunohistochemical (IHC) assays. Methods: Immunohistochemical markers for cytotoxic, inflammatory, and anti-inflammatory responses and morphometric methods were applied to routine paraffin sections of skin biopsies, taken from lesions of 59 patients with discoid lupus, subacute lupus, and lupus tumidus. For the diagnosis of SLE, patients were classified by both the American College of Rheumatology (ACR-82) and the Systemic Lupus International Collaborating Clinics (SLICC-12) systems. Results: Skin samples from CLE/SLE +patients presented higher expression of IL-1β (ARC-82: p = 0.024; SLICC-12: p = 0.0143) and a significantly higher number of cells marked with granzyme B and perforin (ARC: p = 0.0097; SLICC-12: p = 0.0148). Biopsies from CLE/SLE- individuals had higher expression of IL-17 (ARC-82: p = 0.0003; SLICC-12: p = 0.0351) and presented a positive correlation between the density of granzyme A+and FoxP3+ cells (ARC-82: p = 0.0257; SLICC-12: p = 0.0285) and CD8+ cells (ARC-82: p = 0.0075; SLICC-12: p = 0.0102), as well as between granulysin-positive and CD8+ cells (ARC-82: p = 0.0024; SLICC-12: p = 0.0116). Study limitations: Patients were evaluated at a specific point in their evolution and according to the presence or not of systemic disease. The authors cannot predict how many more, from each group, would have evolved towards SLE in the following years. Conclusions: In this cohort, immunohistochemical findings suggested that patients with a tendency to systemic disease will show strong reactivity for IL-1β, while those with purely cutaneous involvement will tend to express IL-17 more intensely.

Results The levels of serum AFP and IL-6 in the control group were lower than those in the control group, and the difference was statistically significant (P10.0 pg/mL were risk factors affecting the prognosis of HBV-related liver failure. Conclusion Serum AFP and IL-6 can predict the prognosis of patients with HBV-related liver failure, which is worthy of clinical study.
RESUMEN
Objective To investigate the expression of CD4+T cell subtypes and related inflammatory factors in patients with neutrophil-predominant frequent acute exacerbation chronic obstructive pulmonary disease(NE-FE-COPD).Methods COPD patients who were treated in the hospital from March 2019 to March 2021 were selected as the research objects.According to different phenotypes,they were divided into the infrequent exacerbator COPD group(IECOPD group,n=11),the eosinophilic dominant frequent acute plus severe COPD group(Eos-FE-COPD group,n=13),and the neutrophil dominant frequent exacerbator COPD group(NE-FE-COPD group,n=15).Patients with normal lung function and smoking history＞10 packs/year were the control group(CTRL group,n=9).Bronchoalveolar lavage fluid(BALF)was collected from each group,and the expression of CD4+T cell subtypes and inflammatory factors were detected by flow cytometry.The correlation between BALF and lung function and the frequency of acute exacerbation was ana-lyzed.CD4+CD28nullT cells and CD4+CD28+T cells were co-cultured with human airway epithelial cells(hAECs)and divided into co-culture group and Control group.The damage of hAECs was observed by immu-nofluorescence staining,and the mRNA and protein expression levels of ZO-1 and occludin were detected by RT-qPCR and Western blot.Results The proportion of CD4+CD28nullT cells and IL-1β level in BALF in the NE-FE-COPD group were higher than those in the CTRL group,the IE-COPD group,and the Eos-FE-COPD group,and the difference was statistically significant(P＜0.05).The proportion of CD4+CD28nullT cells and IL-1βlevel were negatively correlated with lung function(P＜0.05),and positively correlated with acute ex-acerbation frequency(P＜0.05).Compared with the Control group,hAECs tight junctions were damaged in the co-culture group,and mRNA and protein expression levels of ZO-1 and occludin decreased,with statistical significance(P＜0.05).Conclusion CD4+CD28nullT cells and IL-1β may be involved in the occurrence and de-velopment of NE-FE-COPD.
RESUMEN
Objective To investigate the relationship between serum mannan binding lectin(MBL),histi-dine rich glycoprotein(HRG),interleukin(IL)-23/IL-17 inflammatory axis and cerebral vasospasm(CVS)and prognosis in patients with aneurysmal subarachnoid hemorrhage(aSAH)after interventional emboliza-tion.Methods A total of 195 patients with aSAH who underwent interventional embolization treatment in the hospital from March 2019 to February 2022 were selected and were divided into no CVS group(126 cases),mild CVS group(18 cases),moderate CVS group(39 cases),and severe CVS group(12 cases)according to the occurrence and severity of CVS detected by digital subtraction angiography at the 4th postoperative day.The levels of serum MBL,HRG,IL-23 and IL-17 among the four groups before and 3 d after surgery were compared.The patients were followed up for 6 months and divided into good prognosis group(137 cases)and poor prognosis group(58 cases)according to their prognosis.Factors influencing poor prognosis in aSAH pa-tients were analyzed by multivariate Logistic regression model.The predictive value of serum MBL,HRG,IL-23,IL-17 levels and their combined application models for poor prognosis in patients with aSAH was analyzed by receiver operating characteristic(ROC)curve.Results The incidence rate of CVS after interventional em-bolization was 35.38%in 195 patients with aSAH.3 d after surgery,the serum levels of MBL,IL-23 and IL-17 in the mild,moderate,and severe CVS groups were higher than those in the no CVS group,those in the severe CVS group were higher than those in the moderate CVS group,those in the moderate CVS group were higher than those in the mild CVS group(P<0.05).The serum HRG levels in the mild,moderate,and severe CVS groups were lower than those in the non CVS group,those in the severe CVS group were lower than those in the moderate CVS group,those in the moderate CVS group were lower than those in the mild CVS group(P<0.05).3 d after surgery,the levels of serum MBL,IL-23 and IL-17 in the four groups were higher than that before surgery,while the levels of serum HRG were lower than that before surgery(P<0.05).The pro-portions of patients with aneurysm diameter≥6 mm,number of aneurysms>1,surgery time>24 h,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,and serum levels of MBL,IL-23,and IL-17 on the 3rd day after sur-gery in the good prognosis group were lower than those in the poor prognosis group,and serum HRG levels at 3 d after surgery in the good prognosis group were higher than that in the poor prognosis group(P<0.05).Multivariate Logistic regression analysis showed that aneurysm diameter≥6 mm,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,elevated serum levels of MBL,IL-23,and IL-17 and decreased HRG level at 3 d after sur-gery were independent risk factors for poor prognosis in aSAH patients(P<0.05).ROC results showed that serum levels of MBL,HRG,IL-23,and IL-17 at 3 d after surgery had certain predictive power for poor progno-sis in patients with aSAH.The predictive model with the combined application of four indicators had relatively high efficiency(the area under the curve was 0.853).Conclusion Elevated levels of MBL,IL-23,IL-17,and decreased HRG levels in aSAH patients after interventional embolization could increase the risk of CVS and are associated with poor prognosis in aSAH patients after interventional embolization.The above indicators have a certain predictive power for poor prognosis in aSAH patients.
RESUMEN
Objective To explore the levels of interleukin-37(IL-37)and CC type modified chemokine 11(CCL11)in serum of pregnant women infected with group B streptococcus in late pregnancy and their predic-tive efficacy for maternal and infant outcomes.Methods A total of 86 pregnant women with reproductive tract B streptococcus infection in late pregnancy treated in the hospital from December 2020 to December 2022 were selected as the study group,and 76 pregnant women with normal physical examination admitted during the same period were selected as the control group.The levels of IL-37 and CCL11 in serum of all pregnant women were detected by enzyme-linked immunosorbent assay.According to whether the pregnant women with group B streptococcus infection in late pregnancy had adverse maternal and infant outcomes,they were divided into normal pregnancy outcome group(50 cases)and adverse pregnancy outcome group(36 cases).Receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of serum IL-37 and CCL11 on maternal and infant outcomes of pregnant women with reproductive group B streptococcus infection in late pregnancy.Multivariate Logistic regression was used to analyze the factors affecting maternal and in-fant outcomes of pregnant women with reproductive group B streptococcus infection in late pregnancy.Results The levels of IL-37 and CCL11 in the study group were higher than those in the control group(P<0.05).The incidence rate of adverse outcomes in the study group was significantly higher than that in the control group(P<0.05).The proportion of abortion history and the proportion of vaginal microecological disorders and levels of IL-37 and CCL11 and in adverse pregnancy outcome group were higher than those in normal pregnancy outcome group(P<0.05).ROC curve results showed that the area under the curve(AUC)of IL-37 and CCL11 for predicting adverse maternal and infant outcomes of pregnant women infected with group B streptococcus in late pregnancy were 0.876(95%CI:0.824-0.920)and 0.788(95%CI:0.748-0.830),re-spectively.The AUC of the combined prediction of adverse maternal and infant outcomes of pregnant women infected with group B streptococcus were 0.927(95%CI:0.889-0.970).Multivariate Logistic regression a-nalysis results showed that serum IL-37(OR=3.604,95%CI:2.106-6.166),CCL11(OR=4.250,95%CI:2.074-8.709),abortion history(OR=2.707,95%CI:1.688-4.342)and vaginal microecological disorders(OR=3.504,95%CI:1.993-6.162)were risk factors for adverse maternal and infant outcomes in pregnant women infected with group B streptococcus in late pregnancy(P<0.05).Conclusion The levels of IL-37 and CCL11 in serum of pregnant women infected with reproductive group B streptococcus in late pregnancy are in-creased,which are related to adverse pregnancy outcomes,and are expected to be effective indicator for predic-ting adverse pregnancy outcomes of pregnant women infected with reproductive group B streptococcus in late pregnancy.
RESUMEN
Objective To investigate the expression changes and clinical significance of interleukin-1 recep-tor-associated kinase 1(IRAK1)and tumor necrosis factor receptor-associated factor 6(TRAF6)in patients with septic shock.Methods A total of 142 patients with septic shock admitted from November 2020 to No-vember 2022(septic shock group)were selected as the study subjects,and those who came to the hospital for physical examination during the same period were selected as the control group.Patients with septic shock were divided into survival group(100 cases)and death group(42 cases)according to their survival status after 28 days of hospitalization observation and treatment.The expression changes of IRAK1 and TRAF6 in pa-tients with septic shock were monitored at admission and after 2,4 and 6 days of treatment.The dynamic changes of acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score and sequential organ failure assessment(SOFA)score were recorded.Spearman correlation analysis was used to evaluate the correlation between IRAK1,TRAF6 and APACHE Ⅱ score and SOFA score in septic shock patients.The correlation be-tween IRAK1 and TRAF6 was analyzed by Pearson correlation analysis.Logistic regression was used to ana-lyze the factors influencing survival status of patients with septic shock.The diagnostic value of IRAK1 and TRAF6 in survival of patients with septic shock was analyzed by the receiver operating characteristic curve.Results The relative expression levels of IRAK1 and TRAF6 in septic shock group were significantly lower than those in control group,and APACHE Ⅱ score and SOFA score were significantly higher than those in control group,with statistical significance(P＜0.05).Compared with admission,the relative expression levels of IRAK1 and TRAF6 in 2,4 and 6 days after treatment were significantly increased,while APACHE Ⅱ score and SOFA score were significantly decreased,with statistical significance(P＜0.05).Compared with the death group,the relative expression levels of IRAK1 and TRAF6 in the survival group were higher at each corre-sponding time point,and the APACHE Ⅱ score and SOFA score were lower,with statistical significance(P＜0.05).Correlation analysis showed that IRAK1 and TRAF6 were negatively correlated with APACHE Ⅱscores and SOFA scores in septic shock patients,while IRAK1 and TRAF6 were positively correlated(r=0.688,P＜0.05).IRAK1,TRAF6 and APACHE Ⅱ scores were independent risk factors for survival of septic shock patients(P＜0.05).The AUC of the combined diagnosis of IRAK1 and TRAF6 was significantly larger than that of IRAK1 alone(Z=2.044,P=0.041)and that of TRAF6 alone(Z=2.442,P=0.015).Conclusion The expression of IRAK1 and TRAF6 can evaluate the survival and prognosis of patients with septic shock.
RESUMEN
Objective To investigate the predictive value of interleukin-33(IL-33),eosinophil chemotactic factor(Eotaxin),soluble scavenger receptor CD163(sCD163)for recurrent wheezing in children with bronchi-olitis.Methods A total of 120 children with bronchiolitis who were treated in Jiamusi Maternal and Child Health Hospital from August 2019 to October 2021 were enrolled in the study.The clinical data of the chil-dren were collected,including demographic factors,birth factors,atopic factors,length of hospital stay,time from symptom onset to visit,and respiratory distress assessment tool(RDAI)score.Respiratory syncytial vi-rus(RSV)and rhinovirus(RV)were detected.Blood samples were collected for detection.Blood test indica-tors included total immunoglobulin E(IgE),white blood cell count(WBC),IL-33,Eotaxin and sCD163.The discharged children were followed up for 1 year,and they were divided into non-recurrent group and recurrent group according to the number of wheezing episodes.The two groups were compared in terms of clinical data and blood test indicators.Logistic regression was used to analyze the risk factors for recurrent wheezing in children with bronchiolitis.Pearson correlation analysis was used to analyze the correlation between blood test indexes and RDAI score.The receiver operating characteristic(ROC)curve was drawn to analyze the value of IL-33,Eotaxin,and sCD163 levels alone and in combination in predicting recurrent wheezing in children with bronchiolitis.Results Compared with the non-recurrent group,the recurrent group had significantly higher RDAI score,higher proportion of patients with a history of eczema,a personal history of allergy,and a signifi-cantly higher RSV infection rate(P＜0.05).The recurrent group had significantly higher levels of IL-33,Eotaxin,and sCD163 than the non-recurrent group(P＜0.05).Pearson correlation analysis showed that the levels of IL-33,Eotaxin,and sCD163 in children with bronchiolitis were positively correlated with RDAI score(r=0.516,0.611,0.522,P＜0.05).Logistic regression analysis showed that RDAI score,history of eczema,personal history of allergy,RSV infection,increased IL-33 levels,increased Eotaxin levels,and increased sCD163 levels were risk factors for recurrent wheezing in children with bronchiolitis(OR＞1,P＜0.05).The ROC curve found that The area under the curve(AUC)of IL-33,Eotaxin,and sCD163 levels alone and in combination for predicting recurrent wheezing in children with bronchiolitis was 0.829(95％CI:0.757-0.901),0.858(95％CI:0.794-0.922),and 0.857(95％CI:0.789-0.925)and 0.954(95％CI:0.921-0.987).Conclusion Increased levels of IL-33,Eotaxin and sCD163 in children with bronchiolitis can increase the risk of recurrent wheezing,and the combined detection of the three can effectively predict the occurrence of recurrent wheezing.
RESUMEN
Objective To investigate the predictive value of serum interleukin(IL)-34 and soluble uroki-nase-type plasminogen activator receptor(suPAR)for poor prognosis in children with asthma.Methods A total of 184 children with asthma admitted to the hospital from January 2020 to December 2021 were enrolled in the study as the asthma group,and 184 healthy children who underwent physical examination in the hospital during the same period were enrolled as the healthy group.Enzyme-linked immunosorbent assay(ELISA)was used to measure the serum levels of IL-34 and suPAR in the two groups.The children in the asthma group were followed up for 1 year,and the prognosis was evaluated using the Asthma Control Test(ACT)score ta-ble.Logistic regression was used to analyze the influencing factors of poor prognosis in children with asthma.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum IL-34 and suPAR levels for the prognosis of children with asthma.Results The asthma group had significantly higher serum levels of IL-34 and suPAR than the healthy group(P＜0.05).The incidence of poor prognosis was 22.65％(40/181).Compared with the good prognosis group,the poor prognosis group had significantly high-er proportion of children with preterm birth,passive smoking,a family history of asthma,a history of respira-tory infection,pet rearing,severe disease and serum levels of IL-34 and suPAR(P＜0.05),and a significantly lower proportion of children with breast feeding(P＜0.05).The multivariate Logistic regression analysis showed that preterm birth,family history of asthma,severe disease,and high levels of IL-34 and suPAR were risk factors for poor prognosis in children with asthma(P＜0.05),while breastfeeding was a protective factor(P＜0.05).The area under the ROC curve(AUC)of the combination of serum IL-34 and suPAR for predic-ting poor prognosis in children with asthma was 0.896(95％CI:0.842-0.936),which was greater than the AUC of IL-34 alone(Z=2.636,P=0.008)and the AUC of suPAR alone(Z=2.430,P=0.015).Conclusion Children with asthma have elevated serum levels of IL-34 and suPAR,both of which are risk fac-tors for poor prognosis in children with asthma.Both of them have a good predictive value for the prognosis of children with asthma,and the combination of the two has higher predictive efficiency.

Objective To investigate the clinical efficacy of CT-guided pulsed radiofrequency combined with continuous nerve block in the treatment of refractory postherpetic neuralgia(PHN).Methods A total of 208 patients with refractory PHN,who were admitted to the Hengshui Municipal People's Hospital of China between January 2021 and January 2023,were selected as the subjects of study.Using random number table method,the patients were divided into combination group and control group,with 104 patients in each group.The patients of control group received CT-guided pulsed radiofrequency therapy,and the patients of combination group received additional continuous nerve block therapy on the basis of the treatment of control group.The pain degree at different time point,clinical effective rate,number of analgesia remedy times,quality of sleep,and the levels of serum high mobility group box 1(HMGB1),interleukin-1 β(IL-1β)and interleukin-10(IL-10)were compared between the two groups.Results During the follow-up period,4 patients were lost in touch.Finally,103 patients were included in the combination group and 101 patients were included in the control group.The total treatment response rate in the combination group was 89.32％,which was significantly higher than 78.22％in the control group(P＜0.05).There were statistically significant differences in visual analogue scale(V AS)scores and Athens insomnia scale(AIS)scores including the time effect,inter-group effect and time-group interaction effect,between the two groups(P＜0.05).The postoperative one-week,2-week,4-week VAS scores and AIS scores in the combination group were remarkably lower than those in the control group(P＜0.05).The number of analgesia remedy times in the combination group was smaller than that in the control group,and the used dosage of tramadol in the combination group was lower than that in the control group(P＜0.05).Four weeks after treatment,the serum levels of HMGB1,IL-1β and IL-10 in the combination group were lower than those in the control group(P＜0.05).Conclusion For the treatment of refractory PHN,CT-guided pulsed radiofrequency combined with continuous nerve block can effectively alleviate neural inflammatory damage,and improve pain symptoms and sleep quality,besides,its analgesic effect and clinical efficacy are superior to CT-guided pulsed radiofrequency alone.(J Intervent Radiol,2024,33:264-268)
RESUMEN
Objective:To investigate the levels of interleukin-7 (IL-7), T helper cell 9 (Th9), and cytotoxic T cell 9 (Tc9), and to assess the regulation of exogenous IL-7 to Th9 in septic cardiomypathy patients.Methods:A cross-sectional study was conducted. Septic cardiomypathy patients, septic patients, and controls were enrolled in the 7th People’s Hospital of Zhengzhou between June 2018 and January 2022. Plasma and peripheral blood mononuclear cells (PBMCs) were isolated. PBMCs were stimulated with recombinant IL-7. Plasma IL-7, IL-9, and soluble CD127 levels were measured by enzyme-linked immunosorbent assay. CD127 expression on T cells and Th9/Tc9 percentageswere measured by flow cytometry. mRNAexpressions of purine-rich nucleic acid binding protein 1 (PU.1) and forkhead box protein O1 (Foxo1) were semi-quantified by real-time PCR. IL-7-stimulated Th9 cells from septic cardiomypathy patients were co-cultured with autologous CD8 + T cells and human umbilical vein endothelial cells. Target cell death, cytotoxic molecules and cytokines secretions were investigated. Kruskal-Wallis test was used for comparison among groups, while Dunns multiple test was used for comparison between the two groups. Paired t test or Wilcoxon paired test was used for comparison before and after stimulation. Results:A total of 21 septic cardiomypathy patients, 56 septic patients, and 31 controls were enrolled. IL-7 level was lower in septic cardiomypathy patients compared with in septic patients and controls [75.71(42.28, 135.59) pg/mL vs. 118.47(60.18, 171.73) pg/mL vs. 168.42(105.41, 232.30) pg/mL, P<0.05]. Soluble CD127 level was higher in septic cardiomypathy patients and septic patients compared with in controls [96.70(56.76, 147.04) pg/mL vs. 69.75(43.19, 111.28) pg/mL vs. 29.13(19.33, 42.11) pg/mL, P<0.001]. There was no significant difference of CD127 +CD8 + percentage among three groups ( P=0.477). Th9 percentage and Foxo1 mRNA expression was lower in septic cardiomypathy patients compared with in septic patients and controls ( P<0.001). Tc9 percentage, PU.1 mRNA expression and IL-9 level was lower in septic cardiomypathy patients and septic patients compared with in controls ( P<0.001). Th9 percentage, PU.1/Foxo1 mRNA expression, and IL-9 secretion was up-regulated in response to IL-7 stimulation in PBMCs from septic cardiomypathy patients ( P<0.05). IL-7 stimulated Th9 cells from septic cardiomypathy patients promoted CD8 + T cell-mediated target cell death ( P<0.05). Perforin, granzyme B, and interferon-γ levels were also increased in the supernatants ( P<0.05). Conclusion:IL-7 could enhance Th9 cell activity in septic cardiomypathy patients.
RESUMEN
Very early onset inflammatory bowel disease (VEO-IBD) in children refers to an IBD with the onset age of less than 6 years old, clinically characterized by recurrent colitis, perianal lesions, and nutrient absorption disorders.Different from adults, single gene mutation plays an important role in the pathogenesis of VEO-IBD.To date, about 70 single gene defects have been identified involving the pathogenesis of VEO-IBD, including epithelial barrier, neutrophil and phagocyte function, immune cell selection and activation, immunosuppressive mechanism, or apoptosis.Interleukin-10 (IL-10) is an anti-inflammatory cytokine that regulates innate and adaptive immunity, influences the expression of pro-inflammatory molecules and the function of multiple immune cells, and plays a vital role in the development and progression of IBD.Patients with defects in the IL-10 signaling pathway (IL-10 or IL-10 receptor deficiency) may develop life-threatening colitis as early as childhood.This article reviews the progress in the pathogenesis and treatment of VEO-IBD caused by IL-10 signaling pathway defects.
RESUMEN
Objective To determine the correlation between single-nucleotide polymorphisms of IL-17 with type 2 diabetes in Han population in southeastern Shanxi Provincein.Methods The basic information and related clinical data of the subjects were collected of normal healthy controls and T2DM.Whole blood DNA was extracted,and IL-17 polymorphisms(rs2275913,rs3819024,rs4711998 and rs8193036)were analyzed by using a polymerase chain reaction-high temperature ligase reaction.Results There was no significant difference in the genotype and allele frequency distribution of the four SNP loci of IL-17 gene between the two groups(P>0.05).IL-17 polymorphism was not linked with T2DM in multiple genetic models after controlling for age,BMI,WC,and dyslipidemia(P>0.05).Further analysis showed that the levels of AA genotype was substantially lower of FPG and HOMA-IR levels when compared with the AG and GG genotypes,and the differences among the three groups were statistically significant(P<0.05).However,BMI,FINS,HbA1c and HOMA-βwas no statistical significance among the three groups(P>0.05).Besides,WC and HOMA-IR of AA genotype(rs3819024)were notable higher than those of GG genotype in T2DM group(P<0.05).Conclusions The IL-17 gene polymorphisms rs2275913,rs3819024,rs4711998,and rs8193036 in the Han population of southeast Shanxi Province may not be associated with T2DM.In this region Han T2DM patients,AA genotype at rs2275913 of the IL-17 gene is associ-ated to FPG and HOMA-IR,while GG genotype at rs3819024 is related to WC and HOMA-IR,which could be the potential genotype of IL-17 impacting glucose metabolism.
