ABSTRACT

INTRODUCTION AND OBJECTIVES: Primary biliary cholangitis (PBC) may progress to clinically significant portal hypertension (CSPH) before the development of cirrhosis. This study aimed to investigate CSPH incidence as well as the clinicopathological characteristics and predictive value of these features for the prognosis of patients with PBC, especially at early histologic stage. PATIENTS AND METHODS: Patients diagnosed with PBC between January 2013 and April 2022 were retrospectively enrolled. The prognostic value of baseline clinicopathological characteristics for long-term outcomes in PBC patients with CSPH was assessed using Kaplan-Meier survival analysis and COX regression analysis. RESULTS: Among 280 patients with PBC, 104 underwent liver biopsy and 68 were at early histologic stage. CSPH was present in 47.2 % of participants with 20.6 % at early histologic stage. CSPH was a risk factor for predicting the liver transplant-free survival in PBC patients (hazard ratio [HR], 6.78; 95 % CI, 2.94-15.63), especially those at early stage. Perisinusoidal fibrosis and nodular regenerative hyperplasia (NRH) were common histopathological features in PBC patients with CSPH at the early stages. Fibrous septa formation in the hepatic lobules (HR, 4.85; 95 % CI, 1.51-15.52) and cholestasis (HR, 7.70; 95 % CI, 2.56-23.18) were independent predictors of adverse outcomes. CONCLUSIONS: CSPH indicates an increased risk of adverse outcomes in PBC patients, especially those in early histologic stage. Perisinusoidal fibrosis and NRH are valuable histological features of CSPH in patients with early-stage PBC. Identification of clinicopathological features and assessment of portal hypertension (especially at early stage), contribute to the development of personalized strategies.

ABSTRACT

NLRP1, the first identified inflammasome-forming sensor, is thought to be involved in cancer, yet its definite function in lung adenocarcinoma (LUAD) remains unclear. Herein, we explored the expression and function of NLRP1 in LUAD. Decreased NLRP1 expression was identified in LUAD, which was associated with a poor prognosis. Overexpression of NLRP1 inhibited tumor growth in vitro and in vivo. Mechanically, this effect was observed regardless of inflammasome activation. Further studies revealed that overexpression of NLRP1 downregulated the phosphorylation of DRP1 and promoted mitochondrial fusion, which was mediated by inhibition of NF-κB activity. NF-κB agonist could neutralize the effect of NLRP1 on mitochondrial dynamics. In addition, LUAD sensitivity to cisplatin was enhanced by decreased mitochondrial fission resulting from up-regulated NLRP1. In conclusion, our findings demonstrated an unexpected role of NLRP1 in LUAD by modulating mitochondrial activities, which provides strong evidence for its potential in LUAD treatment.

ABSTRACT

Sepsis is a systemic inflammatory response syndrome in which the host response to infection is dysregulated, leading to circulatory dysfunction and multi-organ damage. It has a high mortality rate and its incidence is increasing year by year, posing a serious threat to human life and health. Mesenchymal stem cells (MSC) have the following properties: hematopoietic support, provision of nutrients, activation of endogenous stem/progenitor cells, repair of tissue damage, elimination of inflammation, immunomodulation, promotion of neovascularization, chemotaxis and migration, anti-apoptosis, anti-oxidation, anti-fibrosis, homing, and many other effects. A large number of studies have confirmed that MSC from different sources have their own characteristics. This article reviews the pathogenesis of sepsis, the biological properties of MSC, and the advantages and disadvantages of different sources of MSC for the treatment of sepsis and their characteristics.

ABSTRACT

BACKGROUND: Graft-versus-host disease (GVHD) is a major complication after allogeneic hematopoietic stem cell transplantation. OBJECTIVE: To elucidate the role of Toll-like receptor 4 (TLR4), the major receptor for bacterial lipopolysaccharide, in the development of GVHD, we constructed a GVHD model in TLR4 knockout (TLR4-/-) mice and monitored the cell chimerism. METHODS: In this study, we used polymerase chain reaction to identify whether TLR4 knockout (TLR4-/-) mice were established. Before transplantation, we pretreated mice with irradiation so as to obtain an appropriate irradiation dose. Flow cytometry was applied to measure the chimerism status, the distributions of antigen-presenting cells (APCs), and T-cells in TLR4+/+ and TLR4-/- recipient mice. RESULTS: The general condition of TLR4-/- recipients was better than that of TLR4+/+ recipients, and the TLR4-/- recipient mice showed less severe GVHD manifestations than the TLR4+/+ recipient mice. Most of the APCs and T-cells in the host mouse spleen were derived from donor cells, and CD4+ T-cells, including memory T-cells, were in the majority in host mice. CONCLUSION: In general, our data show that TLR4 deletion attenuated GVHD development, which suggests that TLR4 could be used as a novel target and therapeutic paradigm in GVHD therapies.


ANTECEDENTES: La enfermedad de injerto contra huésped (EICH) es una complicación importante después del trasplante alogénico de células madre hematopoyéticas. OBJETIVOS: Para dilucidar el papel de TLR4, el principal receptor de LPS bacteriano, en el desarrollo de GVHD, construimos un modelo de GVHD en ratones knockout para TLR4 (TLR4-/-) y monitoreamos el quimerismo celular. MÉTODOS: En este estudio, usamos PCR para identificar si se establecieron ratones knockout para TLR4 (TLR4-/-). Antes del trasplante, pretratamos a los ratones con irradiación para obtener la dosis de irradiación adecuada. Se aplicó citometría de flujo para medir el estado de quimerismo, las distribuciones de APC y células T en ratones receptores TLR4+/+ y TLR4-/-. RESULTADOS: El estado general de los receptores de TLR4-/- fue mejor que el de los receptores de TLR4+/+, y los ratones receptores de TLR4-/- mostraron manifestaciones de GVHD menos graves que los ratones receptores de TLR4+/+. La mayoría de las APC y las células T en el bazo del ratón huésped se derivaron de las células del donante, y las células T CD4+, incluidas las células T de memoria, se encontraban en su mayoría en los ratones huéspedes. CONCLUSIÓN: En general, nuestros datos muestran que la eliminación de TLR4 atenuó el desarrollo de GVHD, lo que sugiere que TLR4 podría usarse como un nuevo objetivo y paradigma terapéutico en las terapias de GVHD.

ABSTRACT

BACKGROUND: Complete thrombosis of the false lumen facilitates remodeling of type B aortic dissection (TBAD). Morphological characteristics affect thrombosis in the false lumen. OBJECTIVES: Discuss the factors present before admission that influence false lumen thrombosis in patients with TBAD. METHODS: We studied 282 patients diagnosed with TBAD in our hospital between January 2008 and December 2017. We divided the subjects into a thrombotic group and a non-thrombotic group based on whether any thrombus was detectable in the false lumen. We analyzed the differences between the two groups with respect to clinical data, the vertical length of the dissection, and the diameter of the aorta. P values < 0.05 were considered statistically significantly different. RESULTS: Significant differences between the thrombotic group and non-thrombotic group were found with respect to age (53.92 ± 11.40 vs. 50.36 ± 10.71, p = 0.009) and proportion of patients with renal insufficiency (7.83% vs. 16.38%, p = 0.026). In zones 3-9, the true lumen diameter of the thrombotic group was significantly larger than in the non-thrombotic group (p < 0.05). Binary logistic regression analysis showed that true lumen diameter in zone 5 and renal insufficiency were independent predictors of false lumen thrombosis. CONCLUSIONS: Age and renal function were associated with thrombosis in the false lumen. Potentially, the difference between the diameter of the true lumen diameter and that of the false lumen may influence the thrombosis of the false lumen.


FUNDAMENTO: A trombose completa da falsa luz facilita a remodelação da dissecção aórtica tipo B (DATB). As características morfológicas afetam a trombose na falsa luz. OBJETIVOS: Discutir os fatores pré-admissão presentes, que influenciam a trombose da falsa luz em pacientes com DATB. METODOLOGIA: Ao todo, 282 pacientes diagnosticados com DATB em nosso hospital foram estudados, no período entre janeiro de 2008 e dezembro de 2017. Os indivíduos foram divididos em um grupo trombótico e um grupo não trombótico, com base na detecção de qualquer trombo na falsa luz. Analisamos as diferenças entre os dois grupos com relação aos dados clínicos, o comprimento vertical da dissecção e o diâmetro da aorta. Valores de p < 0,05 foram considerados estatisticamente diferentes de modo significativo. RESULTADOS: Diferenças significativas entre o grupo trombótico e o grupo não trombótico foram encontradas com relação à idade (53,92 ± 11,40 vs. 50,36 ± 10,71, p = 0,009) e proporção de pacientes com insuficiência renal (7,83% vs. 16,38%, p = 0,026). Nas zonas 3­9, o diâmetro da luz verdadeira do grupo trombótico foi significativamente maior do que no grupo não trombótico (p < 0,05). A análise de regressão logística binária mostrou que o diâmetro da luz verdadeira na zona 5 e a insuficiência renal foram preditores independentes de trombose da falsa luz. CONCLUSÕES: A idade e a função renal estiveram associadas à trombose na falsa luz. Potencialmente, a diferença entre o diâmetro da luz verdadeira e o da falsa luz pode influenciar na trombose da falsa luz.

ABSTRACT

Influenza is an infectious acute respiratory disease with complications and a high mortality rate; the effective medicines for influenza therapy are limited. "Huanglian" or Coptidis Rhizoma, Coptis chinensis Franch., Ranunculaceae, and "ganjiang" or Zingiberis Rhizoma, Zingiber officinale Roscoe, Zingiberaceae, combination is clinically used for treating respiratory diseases. HPLC was applied for the quantification of berberine hydrochloride (1.101 mg/ml) and 6-gingerol (38.41 µg/ml) in the H2O-soluble extract of the herbal formulation. In this study, the effect of "huanglian"- "ganjiang" extract on influenza virus H1N1-induced acute pulmonary inflammation was evaluated, in addition to the investigation of its anti-influenza mechanism in a mouse model. The analyzed herbal combination inhibited the expression of cytokine IL-6 and stimulated the expression of IL-2 in the serum of influenza virus-infected mice. Meanwhile, the herbal combination downregulated the gene and protein expression levels of TLR3, TLR7, MyD88, RIG-I, MAVS, TRAF3, and NF-κB p65, which are key targets of toll-like and RIG-I-like receptor signaling pathways in mice. In addition, the herbal combination could also promote the combination of intracellular autophagosomes and lysosomes in autophagosome-lysosome formation and improve impaired fusion of autophagosomes and lysosomes by influenza virus. This study suggested that the "huanglian"- "ganjiang" extract may be a candidate therapeutic strategy for the treatment of H1N1 influenza.

ABSTRACT

PURPOSE: Aberrant activation of STAT3 signal pathway promotes tumor progression in many solid tumor types, including cervical cancer and endometrial cancer. BBI608, the STAT3 inhibitor had been reported in previous studies for restraining cancer stem cells. However, whether BBI608 is available for inhibiting the proliferation of cervical cancer or endometrial cancer remains poorly understood. This study investigated the anti-tumor effect and molecular mechanism of BBI608 on the patient-specific primary cells (PSPC) generated from cervical and endometrial cancer in vitro. METHODS: PSPCs were obtained from four patients via biopsy. The cell viability was analyzed by the CCK8 assay. The PSPCs were treated with various concentrations of BBI608 or/and paclitaxel; and then, western blot was applied to investigate the expression of phosphorylated STAT3 (pSTAT3). RESULTS: The PSPCs cell viability was reduced after treated with BBI608 at a lower concentration. Western blot results showed a reduction trend of pSTAT3 after PSPCs treated with BBI608. Our results demonstrated that BBI608 at the certain concentrations worked well in reducing the cell viability of PSPC from the patients who suffered from cervical cancer and endometrial cancer. CONCLUSIONS: In this study, the patient-specific primary cell (PSPC) was used as the pre-clinical model for investigating the efficiency of BBI608 in reducing cancer cells viability. BBI608, at a clinical-relevant concentration, had valid efficiency in PSPCs from the patients. The dose of drugs treatment and the measured results were more valuable for further guiding clinical trials.

ABSTRACT

Resumo Objetivo Avaliar os efeitos da intervenção terapêutica de enfermagem baseada no modelo de trajetória da doença crônica na ansiedade e na qualidade de vida de pacientes com doença cardíaca coronária (DCC). Métodos Um total de 118 pacientes com DCC admitidos entre fevereiro de 2019 e fevereiro de 2021 foram distribuídos aleatoriamente em grupos controle e observação (n = 59). O grupo controle recebeu intervenção de enfermagem de rotina, enquanto o grupo observação recebeu intervenção com base no modelo de trajetória da doença crônica. Os sintomas clínicos, a escala de autoavaliação de ansiedade (SAS), a qualidade de vida (QV) e as pontuações de autoeficácia foram comparados. As taxas de incidência de complicações foram comparadas. A análise de regressão linear multivariada foi realizada para o efeito mediador da autoeficácia na relação entre ansiedade e QV. Um modelo de equação estrutural foi construído e validado. Resultados Após a intervenção, os sintomas clínicos e a pontuação da SAS diminuíram significativamente em ambos os grupos, especialmente no grupo observação (P<0,05). As pontuações de QV e autoeficácia aumentaram significativamente em ambos os grupos, particularmente no grupo de observação (P<0,05). A pontuação de autoeficácia correlacionou-se negativamente com a pontuação SAS e positivamente com a pontuação QV. Houve correlação negativa entre a pontuação SAS e a pontuação QV (P<0,05). O modelo de autoeficácia, ansiedade e QV apresentou boa adequação, e o efeito mediador da autoeficácia na relação entre ansiedade e QV foi de 0,896. A taxa de incidência de complicações foi significativamente menor no grupo observação do que no grupo controle (P <0,05). Conclusão A intervenção de enfermagem baseada no modelo de trajetória da doença crônica alivia significativamente a ansiedade, melhora a QV e aumenta a pontuação de autoeficácia de pacientes com DCC. A autoeficácia é um mediador da relação entre ansiedade e QV.

Abstract Objective We aimed to assess the effects of nursing intervention therapy based on chronic disease trajectory model on anxiety and quality of life (QOL) of patients with coronary heart disease (CHD). Methods A total of 118 CHD patients admitted from February 2019 to February 2021 were randomly assigned into control and observation groups (n=59). Control group was given routine nursing intervention, while observation group was given intervention based on chronic disease trajectory model. Clinical symptom, self-rating anxiety scale (SAS), QOL and self-efficacy scores were compared. Incidence rates of complications were compared. Multivariate linear regression analysis was performed for the mediating effect of self-efficacy on relationship between anxiety and QOL. A structural equation model was constructed and verified. Results After intervention, clinical symptom and SAS scores significantly declined in both groups, especially in observation group (P<0.05). QOL and self-efficacy scores rose significantly in both groups, particularly in observation group (P<0.05). Self-efficacy score was negatively correlated with SAS score and positively correlated with QOL score, and there was a negative correlation between SAS score and QOL score (P<0.05). The model of self-efficacy, anxiety and QOL had good fitness, and the mediating effect of self-efficacy on relationship between anxiety and QOL was 0.896. The incidence rate of complications was significantly lower in observation group than in control group (P<0.05). Conclusion Nursing intervention based on chronic disease trajectory model significantly relieves the anxiety, improves QOL, and increases the self-efficacy score of CHD patients. Self-efficacy is a mediator for the relationship between anxiety and QOL.

ABSTRACT

PURPOSE: This study investigated the effects of oral administration of Clostridium butyricum (C. butyricum) on inflammation, oxidative stress, and gut flora in rats with hepatic ischemia reperfusion injury (HIRI). METHODS: The rats from C. butyricum group were given C. butyricum for 5 days. Then, hepatic ischemia for 30 min and reperfusion for 6 h were performed in all the rats. After the animals were sacrificed, alanine transaminase (ALT), aspartate aminotransferase (AST), lipopolysaccharide (LPS) in serum, short-chain fatty acids (SCFAs), and gut microbiota composition in feces, and malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), Toll-like receptor 4 (TLR4), nuclear factor-kappa Bp65 (NF-κBp65) and histological analysis in the liver were performed. RESULTS: The rats given C. butyricum showed decreased ALT, AST, LPS, and MDA; improved GSH and histological damage; changes in SCFAs; declined TNF-α, IL-6, TLR4, and pNF-κBp65/NF-κBp65; and changes in the gut microbial composition, which decreased the Firmicutes/Bacteroidetes ratio and increased the relative abundance (RA) of probiotics. CONCLUSIONS: C. butyricum supplementation protected against HIRI by regulating gut microbial composition, which contributed to the decreased LPS and attenuation of inflammation and oxidative stress. These indicate C. butyricum may be a potent clinical preoperative dietary supplement for HIRI.

ABSTRACT

Character strengths could effectively prevent negative psychological outcomes in adults. However, there was little research conducted among early adolescents. The present study aimed to explore character strengths that were independently related to fewer behavior problems in early adolescents. In total, 521 early adolescents (mean age 10.92 ± 0.04, range 10-12 years) were recruited from primary schools in Sichuan, China. Character strengths were measured using the Values in Action Inventory of Strengths for Youth (VIA-Youth). Behavior problems were measured using the Conners Parent Symptom Questionnaire (PSQ). The results showed that behavior problems were negatively correlated with character strengths (r = -0.14 to -0.3, p < 0.05 Bonferroni corrected). Character strengths explained a significant proportion of additional variance (14-22%) in five types of behavior problems after controlling the effect of demographic factors (residence, left-behind experiences, maternal education level). Moreover, several specific character strengths showed an independent contribution (ß = -0.34 to -0.14 for self-regulation, perseverance, zest, humility, and leadership; ß = 0.21 to 0.34, for hope; all p < 0.05) to behavior problems. Our study revealed that character strengths were protective factors against behavior problems in early adolescents.

ABSTRACT

Character strengths could efectively prevent negative psychological outcomes in adults. However, there was little research conducted among early adolescents. The present study aimed to explore character strengths that were independently related to fewer behavior problems in early adolescents. In total, 521 early adolescents (mean age 10.92 ± 0.04, range 10­12 years) were recruited from primary schools in Sichuan, China. Character strengths were measured using the Values in Action Inventory of Strengths for Youth (VIA-Youth). Behavior problems were measured using the Conners Parent Symptom Questionnaire (PSQ). The results showed that behavior problems were negatively correlated with character strengths (r = −0.14 to −0.3, p < 0.05 Bonferroni corrected). Character strengths explained a signifcant proportion of additional variance (14­22%) in fve types of behavior problems after controlling the efect of demographic factors (residence, left-behind experiences, maternal education level). Moreover, several specifc character strengths showed an independent contribution (ß = −0.34 to −0.14 for self-regulation, perseverance, zest, humility, and leadership; ß = 0.21 to 0.34, for hope; all p < 0.05) to behavior problems. Our study revealed that character trengths were protective factors against behavior problems in early adolescents.

ABSTRACT

Purpose: This study investigated the effects of oral administration of Clostridium butyricum (C. butyricum) on inflammation, oxidative stress, and gut flora in rats with hepatic ischemia reperfusion injury (HIRI). Methods: The rats from C. butyricum group were given C. butyricum for 5 days. Then, hepatic ischemia for 30 min and reperfusion for 6 h were performed in all the rats. After the animals were sacrificed, alanine transaminase (ALT), aspartate aminotransferase (AST), lipopolysaccharide (LPS) in serum, short-chain fatty acids (SCFAs), and gut microbiota composition in feces, and malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), Toll-like receptor 4 (TLR4), nuclear factor-kappa Bp65 (NF-κBp65) and histological analysis in the liver were performed. Results: The rats given C. butyricum showed decreased ALT, AST, LPS, and MDA; improved GSH and histological damage; changes in SCFAs; declined TNF-α, IL-6, TLR4, and pNF-κBp65/NF-κBp65; and changes in the gut microbial composition, which decreased the Firmicutes/Bacteroidetes ratio and increased the relative abundance (RA) of probiotics. Conclusions: C. butyricum supplementation protected against HIRI by regulating gut microbial composition, which contributed to the decreased LPS and attenuation of inflammation and oxidative stress. These indicate C. butyricum may be a potent clinical preoperative dietary supplement for HIRI.

ABSTRACT

Abstract Objective: To investigate the impact of recombinant human interferon α1b (rhIFNα1b) treatment in infants hospitalized with lower respiratory tract infections on subsequent wheezing. Methods: The clinical data of infants (n = 540) with viral pneumonia, wheezy bronchitis, or bronchiolitis hospitalized in 19 Chinese hospitals from June 2009 to June 2015 were retrospectively analyzed. The parameters relevant to wheezing episodes within the last year were collected by telephone and questionnaires. The rhIFNα1b treatment group (n = 253) and control group (n = 287) were compared in terms of wheezing episodes within the last year. Moreover, the wheezing group (95 cases) and non-wheezing group (445 cases) were compared. Results: Out of 540 cases, 95 (17.6%) experienced wheezing episodes, 13.8% (35/253) cases treated with rhIFNα1b, and 20.9% (60/287) cases without rhIFNα1b experienced wheezing episodes within the last year. The rhIFNα1b treatment significantly improved wheezing episodes within the last year, compared with the control peers (p = 0.031). Single-factor regression showed statistically significant differences between the wheezing and non-wheezing groups in terms of age, rhIFNα1b use, childhood and family history of allergy, housing situation, and feeding history (p < 0.05). Binary logistic regression showed a childhood history of allergy (OR = 2.14, p = 0.004), no rhIFNα1b use (OR = 1.70, p = 0.028), and living in a crowded house (OR = 1.92, p = 0.012) might be risk factors of subsequent wheezing. Accordingly, breastfeeding (OR = 0.44, p = 0.008) and hospitalization age of 1-year-old (OR = 0.58, p = 0.024) were protective factors. Conclusions: Early use of rhIFNα1b in infants hospitalized with lower respiratory tract infections and breastfeeding could prevent subsequent wheezing. Living in a crowded house could promote subsequent wheezing.

ABSTRACT

Importance: Hypertension is highly prevalent in low- and middle-income countries, and it is an important preventable risk factor for cardiovascular diseases (CVDs). Understanding the economic benefits of a hypertension control program is valuable to decision-makers. Objective: To evaluate the long-term cost-effectiveness of a multicomponent hypertension management program compared with usual care among patients with hypertension receiving care in public clinics in Argentina from a health care system perspective. Design, Setting, and Participants: This economic evaluation used a Markov model to estimate the cost-effectiveness of a hypertension management program among adult patients with uncontrolled hypertension in a low-income setting. Patient-level data (743 individuals for multicomponent intervention; 689 for usual care) from the Hypertension Control Program in Argentina trial (HCPIA) were used to estimate treatment effects and the risk of CVD. Three health states were included in each strategy: (1) low risk of CVD, (2) high risk of CVD, and (3) death. The total time horizon was the lifetime, and each cycle lasted 6 months. Main Outcomes and Measures: Model inputs were based on trial data and other published sources. Cost and utilities were discounted at a rate of 5% annually. The incremental cost-effectiveness ratio (ICER) between the multicomponent intervention and usual care was calculated using the difference in costs in 2017 international dollars (INT $) divided by the difference in effectiveness in quality-adjusted life-years (QALYs). One-way sensitivity analysis and probabilistic sensitivity analysis were performed to assess the uncertainty and robustness of the results. Results: In the original trial, the 743 participants in the intervention group (349 [47.0%] men) had a mean (SD) age of 56.2 (12.0) years, and the 689 participants in the control group (311 [45.1%] men) had a mean (SD) age of 56.2 (11.7) years. In the base-case analysis, the HCPIA program yielded 8.42 discounted QALYs and accrued INT $3096 discounted costs, while usual care yielded 8.29 discounted QALYs and accrued INT $2473 discounted costs. The ICER for the HCPIA program was INT $4907/QALY gained. The model results remained robust in sensitivity analyses, and the model was most sensitive to parameters of program costs. Conclusions and Relevance: In this study, the HCPIA multicomponent intervention vs usual care was a cost-effective strategy to improve hypertension management and reduce the risk of associated CVD among patients with hypertension who received services at public clinics in Argentina. This intervention program is likely transferable to other settings in Argentina or other lower- and middle-income countries.

ABSTRACT

INTRODUCTION: Emerging evidence indicates that physiological and pathological conditions of the nose are posttranscriptionally regulated by microRNAs, a class of small noncoding RNAs. Recently, microRNA-223-3p has been increasingly implicated in the modulation of allergic rhinitis OBJECTIVE: This study aimed to assess the role and mechanism of microRNA-223-3p in a mouse model of allergic rhinitis. METHODS: The expression level of miR-223-3p was measured in the serum of 41 allergic rhinitis patients and 39 healthy controls using quantitative real time polymerase chain reaction. BALB/c mice were used to establish an allergic rhinitis model by intraperitoneal sensitization and intranasal challenge with ovalbumin. MicroRNA-223-3p agomir/antagomir was then intranasally administered to mice after ovalbumin challenge for another week. The symptoms of nasal rubbing and sneezing were recorded. Serum ovalbumin-specific immunoglobulin E concentration, microRNA-223-3p expression and proinflammatory cytokine (IL-4, IL-5, IFN-γ) levels in nasal mucosa were measured by ELISA and quantitative real time polymerase chain reaction, respectively. Histopathologic changes were evaluated using hematoxylin and eosin staining. RESULTS: MicroRNA-223-3p levels increased significantly in both allergic rhinitis patients and allergic rhinitis mice. In addition, upregulation of microRNA-223-3p levels by nasal administration of microRNA-223-3p agomir also markedly increased the concentration of ovalbumin -specific IgE, the frequencies of nasal rubbing and sneezing, the levels of proinflammatory cytokines (IL-4, IL-5, IFN-γ) and eosinophil infiltration in the nasal mucosa of allergic rhinitis mice. Moreover, microRNA-223-3p antagomir appeared to strongly ameliorate the symptoms and pathology in nasal mucosa. Subsequently, we demonstrated for the first time that microRNA-223-3p negatively regulated INPP4A expression by binding with the 3' untranslated region (3'UTR) of INPP4A. CONCLUSIONS: These findings indicate that microRNA-223-3p plays an important role in regulating the pathology and symptoms of allergic rhinitis by targeting INPP4A.
