The aim of this study was to determine the prevalence of this pathology and its associated factors among bakery workers in Abidjan. Materials and Methods: This descriptive and analytical cross-sectional study was conducted over a period of four (4) months from 18 December 2019 to 18 April 2020. Two questionnaires were used, one on employees and the other on the indoor environment of bakeries. In addition, a spirometry test was performed on all bakery workers. Statistical analysis was performed using stata 15.1 software. Results: A total of 599 bakery employees, including bakers (59.73%), sales assistants/ cashiers (23.52%), cleaners (6.34%) and administrative staff (10.18%), were investigated. The mean age was 30.8 ± 8 years, with a sex ratio (M/F) = 2.2. Asthma symptoms were found in 95 (15.86%) employees, of whom 74 (77.9%) had work-related asthma and 11 (14.9%) had asthma aggravated by work. The factors associated with work-aggravated asthma were personal or family history of allergy or atopy [ORa = 3.75;CI95%: 1.56 - 8.93;p = 0.003], exposure to dust [ORa = 5.01;CI95%: 1.43 - 7.50;p = 0.011] and humidity level (60% - 70%) [ORa = 1.80;CI 95%: 0.99 - 3.28;p = 0.05]. Conclusion: Work-aggravated asthma is a reality in bakeries in Abidjan, with an estimated prevalence of 14.9%. Two of the three factors associated with this condition suggest a link with indoor air pollution. Combating air pollution in these establishments must therefore be a priority for the relevant authorities, in order to provide employees with a working environment that protects their health.展开更多

Out of the 183 children in the ADHD group, 25 had comorbid asthma, resulting in a comorbidityrate of 13.66% (25/183), compared to the comorbidity rate of 2.91% (16/549) among the 549 children in the controlgroup. The difference in the asthma comorbidity rate between the two groups was statistically significant (P <0.05). The results of the multivariate logistic regression analysis indicated that family history of asthma and allergicdiseases, maternal complications during pregnancy, maternal use of asthma and allergy medications duringpregnancy, maternal anxiety and depression during pregnancy, and parental relationship status are independentrisk factors increasing the risk of comorbid asthma in children with ADHD (P < 0.05).CONCLUSIONChildren with ADHD were more likely to have comorbid asthma than healthy control children were. A familyhistory of asthma, adverse maternal factors during pregnancy, and parental relationship status were identified asrisk factors influencing the comorbidity of asthma in children with ADHD. Clinically, targeted interventions basedon these factors can be implemented to reduce the risk of comorbid asthma.

Its incidence is closely related to the degree of industrial development, but also related to the nature of asthma. In some specific industries, such as workers who are exposed to asthmatic isocyanates for a long time, the incidence of occupational asthma can reach 5%-10%, and the incidence of occupational asthma can even reach 50% or higher among workers engaged in the detergent industry who are in contact with proteolytic enzymes for a long time. Objective To analyze the clinical value of early comprehensive rehabilitation nursing for patients with occupational asthma, methods a total of 48 patients with occupational asthma who were admitted from January 2020 to December 2022 were divided into control group and study group by random number table method The disappearance time of chest tightness and shortness of breath, the disappearance time of wheezing and cough, and the FEV1, forced vital capacity (FVC) and peak expiratory flow (PEF) indexes before and after treatment were compared between the two groups after nursing, the disappearance time of clinical symptoms in the study group was shorter than that in the control group, and the levels of FEV1, FVC and PEF were higher than those in the control group, and the P < 0.05 was significantly improved.展开更多

Methods: We separated 42 healthy male SD rats into two groups, a control group (7) and a model group (35).The model group was sensitized with a combination of ovalbumin (OVA) and aluminum hydroxide for 2 weeks, while the control group was given an equal amount of physiological saline.After 2 weeks, the modeling group was randomly divided into Model group, Yanghe Pingchuan Granules high, medium and low dose groups and Dexamethasone group, each group consisted of 7 animals. After 4 weeks, OVA atomization and gavage were used for stimulation and treatment. Yanghe Pingchuan Granules high, middle and low groups were given 15.48, 7.74, 3.87 g∙kg-1 Yanghe Pingchuan Granules daily, dexamethasone group was given 0.0625 mg∙kg-1 dexamethasone daily, and the other groups were given the same amount of normal saline. HE, PAS and Masson staining were used to observe the lung histopathological changes in rats. The levels of interleukin-6, IL-23 and IL-17A were detected by ELISA. The expression levels of JAK-2, P-JAK2, STAT3 and P-STAT3 in lung tissues were detected by Western blot. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the mRNA expression levels of IL-6, JAK2 and STAT3 in rat lung tissue. Results: The lung tissue structure of the model group was severely damaged compared to the control group, accompanied by a great many of inflammatory cell infiltration, goblet cell hyperplasia, subepithelial collagen fiber deposition and airway epithelial thickening were more obvious. The expressions of IL-6, IL- 23 and IL-17A in serum were significantly increased (P<0.01), the protein expression levels of JAK-2, P-JAK2, STAT3 and P-STAT3 and the mRNA expression levels of IL-6, JAK2 and STAT3 in lung tissue were significantly increased (P<0.01);Compared with the model group, inflammatory cell infiltration, goblet cell proliferation, subepithelial collagen fiber deposition and airway epithelial thickening were significantly reduced in each administration group, and the expressions of IL-6, IL-23 and IL-17A in serum were significantly decreased (P< 0.01). The protein expression levels of JAK-2, P-JAK2, STAT3 and P-STAT3 and mRNA expression levels of IL-6, JAK2 and STAT3 in lung tissue were significantly decreased (P<0.01). Conclusion: Yanghe Pingchuan Granules can significantly alleviate airway remodeling in asthmatic rats, and its mechanism may be through inhibiting the IL-6/JAK2/STAT3 signal axis.展开更多

文摘Glycosylation is a common post-translational modification in eukaryotic cells.It is involved in the production of many biologically active glycoproteins and the regulation of protein structure and function.Core fucosylation plays a vital role in the immune response.Most immune system molecules are core fucosylated glycoproteins such as complements,cluster differentiation antigens,immunoglobulins,cytokines,major histocompatibility complex molecules,adhesion molecules,and immune molecule synthesis-related transcription factors.These core fucosylated glycoproteins play important roles in antigen recognition and clearance,cell adhesion,lymphocyte activation,apoptosis,signal transduction,and endocytosis.Core fucosylation is dominated by fucosyltransferase 8(Fut8),which catalyzes the addition ofα-1,6-fucose to the innermost GlcNAc residue of N-glycans.Fut8 is involved in humoral,cellular,and mucosal immunity.Tumor immunology is associated with aberrant core fucosylation.Here,we summarize the roles and potential modulatory mechanisms of Fut8 in various immune processes of the gastrointestinal system.
文摘Introduction: Work-aggravated asthma is pre-existing or concomitant asthma whose symptoms are aggravated by the work environment. The aim of this study was to determine the prevalence of this pathology and its associated factors among bakery workers in Abidjan. Materials and Methods: This descriptive and analytical cross-sectional study was conducted over a period of four (4) months from 18 December 2019 to 18 April 2020. Two questionnaires were used, one on employees and the other on the indoor environment of bakeries. In addition, a spirometry test was performed on all bakery workers. Statistical analysis was performed using stata 15.1 software. Results: A total of 599 bakery employees, including bakers (59.73%), sales assistants/ cashiers (23.52%), cleaners (6.34%) and administrative staff (10.18%), were investigated. The mean age was 30.8 ± 8 years, with a sex ratio (M/F) = 2.2. Asthma symptoms were found in 95 (15.86%) employees, of whom 74 (77.9%) had work-related asthma and 11 (14.9%) had asthma aggravated by work. The factors associated with work-aggravated asthma were personal or family history of allergy or atopy [ORa = 3.75;CI95%: 1.56 - 8.93;p = 0.003], exposure to dust [ORa = 5.01;CI95%: 1.43 - 7.50;p = 0.011] and humidity level (60% - 70%) [ORa = 1.80;CI 95%: 0.99 - 3.28;p = 0.05]. Conclusion: Work-aggravated asthma is a reality in bakeries in Abidjan, with an estimated prevalence of 14.9%. Two of the three factors associated with this condition suggest a link with indoor air pollution. Combating air pollution in these establishments must therefore be a priority for the relevant authorities, in order to provide employees with a working environment that protects their health.

文摘Ovalbumin(OVA)is the major allergenic protein that can induce T helper 2(Th2)-allergic reactions,for which current treatment options are inadequate.In this study,we developed a polymerized hypoallergenic OVA product via laccase/caffeic acid(Lac/CA)-catalyzed crosslinking in conjunction with galactomannan(Man).The formation of high molecular weight crosslinked polymers and the Ig G-binding were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)and Western blotting.The study indicated that Lac/CA-catalyzed crosslinking plus Man conjugation substantially altered secondary and tertiary structures of OVA along with the variation in surface hydrophobicity.Gastrointestinal digestion stability assay indicated that crosslinked OVA exhibited less resistance in simulated gastric fluid(SGF)and simulated intestinal fluid(SIF).Mouse model study indicated that Lac-Man/OVA ameliorated eosinophilic airway inflammatory response and efficiently downregulated the expression of Th2-related cytokines(interleukin(IL)-4,IL-5,and IL-13),and upregulated IFN-γand IL-10 expression.Stimulation of bone marrow-derived dendritic cells with Lac-Man/OVA suppressed the expression of phenotypic maturation markers(CD80 and CD86)and MHC class II molecules,and suppressed the expression levels of proinflammatory cytokines.The knowledge obtained in the present study offers an effective way to acquire a hypoallergenic OVA product that can have a therapeutic effect in alleviating OVA-induced allergic asthma.

文摘Histamine in food has attracted widespread attention due to the potential toxicity and associated health risk.However,its influences on immunological components,especially the function of key immune cells,are still poorly known.In this work,we explored the effects of exogenous histamine on the function of key immune cells such as intestinal epithelial cells,dendritic cells,and T cells.The results showed that histamine could affect the expression of allergy-related genes in CMT93 cells at a high dose of histamine.Moreover,it’s found that histamine could cause an imbalance in the levels of relevant immune factors secreted by dendritic cells and T cells,especially those related to allergy.At the same time,the proportion of MHC class IIpositive dendritic cells and the proportion of T helper 2(Th2)cells in CD4^(+)T cells increased after histamine stimulation.We concluded that the presence of a certain level of histamine in food may affect the expression of allergy-related cytokines,disrupt the balance of the immune homeostasis,and potentially lead to adverse immune reactions.This work demonstrated the importance of including the estimation of histamine’s immune safety in aquatic products rather than merely considering the potential risk of food poisoning.

文摘Objective The function of Bcl-6 in T follicular helper(Tfh)cell maturation is indispensable,and Tfh cells play a pivotal role in asthma.This study investigated the impact of Bcl-6 on asthmatic traits.Methods The microscopic pathological alterations,airway resistance(AR),and lung compliance(LC)were determined in asthmatic mice and Bcl-6 interference mice.The surface molecular markers of Tfh cells and the Bcl-6 mRNA and protein expression were determined by flow cytometry,RT-qPCR,and Western blotting,respectively.The relationships between the Tfh cell ratio and the IgE and IgG1 concentrations in peripheral blood mononuclear cells(PBMCs)and bronchoalveolar lavage fluid(BALF)were determined.Results Asthmatic inflammatory changes were observed in the lung tissue and were attenuated by Bcl-6 siRNA and dexamethasone(DXM).Asthmatic mice exhibited an increased AR and a decreased LC,while Bcl-6 siRNA or DXM mitigated these changes.The percentages of Tfh cells and eosinophils were significantly increased in the asthmatic mice,and they significantly decreased after Bcl-6 inhibition or DXM treatment.RT-qPCR and Western blotting analyses revealed that the Bcl-6 expression level in PBMCs was significantly higher in asthmatic mice,and it decreased following Bcl-6 inhibition or DXM treatment.The IgE expression in the serum and BALF and the B cell expression in PBMCs exhibited a similar trend.In asthmatic mice,the ratio of Tfh cells in the peripheral blood showed a strong positive correlation with the IgE levels in the serum and BALF,but not with the IgG1 levels.Conclusion The amelioration of airway inflammation and airway hyper-responsiveness is achieved through Bcl-6 suppression,which effectively hinders Tfh cell differentiation,ultimately resulting in a concurrent reduction in IgE production.

文摘BACKGROUND Pediatric asthma is a significant public health issue that impacts the quality of life of children globally.Traditional management approaches focus on symptom control and medication adherence but often overlook the comprehensive educational needs of patients and their families.A multifaceted health education approach may offer a more holistic strategy in managing pediatric asthma,especially in outpatient settings.AIM To evaluate the efficacy of a comprehensive health education strategy in improving disease management,medication adherence,and quality of life among children with asthma in outpatient settings.METHODS In total,100 pediatric patients with severe asthma were enrolled from January 2021 to November 2022 and randomly allocated to a control group(n=50)or an observation group(n=50).The control group received standard nursing care,including basic nursing interventions and health education upon admission.In contrast,the observation group was exposed to a broad spectrum of health education methodologies,including internet-based hospital systems,social media channels,one-on-one verbal education,informational brochures,slide present ations,telephone check-ins,animated videos,and illustrated health education manuals.Data on asthma management knowledge,symptom control,quality of life[St.George’s Respiratory Questionnaire(SGRQ)],treatment adherence,and nursing satisfaction were collected and analyzed.RESULTS The scores of the observation group in knowledge areas,such as medication,home care,disease understanding,symptom management,prevention strategies,and nutritional guidance,were significantly higher than those of the control group(P<0.05).In addition,the observation group exhibited greater symptom control,improved quality of life based on their SGRQ scores,and higher treatment adherence post-intervention(P<0.05).Nursing satisfaction was also rated higher in the observation group across all evaluated areas(P<0.05).CONCLUSION Implementing a diversified health education approach in pediatric asthma management significantly enhances disease understanding,symptom management,and treatment adherence,leading to improved quality of life for affected children.These findings underscore the importance of multifaceted clinical health education in augmenting disease awareness and facilitating continuous improvements in asthma control rates,highlighting the potential benefits of incorporating comprehensive educational strategies into pediatric asthma care protocols.
文摘BACKGROUND Bronchial asthma is closely related to the occurrence of attention-deficit hyperactivity disorder(ADHD)in children,which can easily have adverse effects on children’s learning and social interactions.Studies have shown that childhood asthma can increase the risk of ADHD and the core symptoms of ADHD.Compared with children with ADHD alone,children with asthma and ADHD are more likely to show high levels of hyperactivity,hyperactive-impulsive and other externalizing behaviors and anxiety in clinical practice and have more symptoms of somatization and emotional internalization.AIM To explore the relationship between ADHD in children and bronchial asthma and to analyze its influencing factors.METHODS This retrospective cohort study was conducted at Dongying People's Hospital from September 2018 to August 2023.Children diagnosed with ADHD at this hospital were selected as the ADHD group,while healthy children without ADHD who underwent physical examinations during the same period served as the control group.Clinical and parental data were collected for all participating children,and multivariate logistic regression analysis was employed to identify risk factors for comorbid asthma in children with ADHD.RESULTSSignificant differences were detected between the ADHD group and the control group in terms of family history ofasthma and allergic diseases, maternal complications during pregnancy, maternal use of asthma and allergymedications during pregnancy, maternal anxiety and depression during pregnancy, and parental relationshipstatus (P < 0.05). Out of the 183 children in the ADHD group, 25 had comorbid asthma, resulting in a comorbidityrate of 13.66% (25/183), compared to the comorbidity rate of 2.91% (16/549) among the 549 children in the controlgroup. The difference in the asthma comorbidity rate between the two groups was statistically significant (P <0.05). The results of the multivariate logistic regression analysis indicated that family history of asthma and allergicdiseases, maternal complications during pregnancy, maternal use of asthma and allergy medications duringpregnancy, maternal anxiety and depression during pregnancy, and parental relationship status are independentrisk factors increasing the risk of comorbid asthma in children with ADHD (P < 0.05).CONCLUSIONChildren with ADHD were more likely to have comorbid asthma than healthy control children were. A familyhistory of asthma, adverse maternal factors during pregnancy, and parental relationship status were identified asrisk factors influencing the comorbidity of asthma in children with ADHD. Clinically, targeted interventions basedon these factors can be implemented to reduce the risk of comorbid asthma.

文摘BACKGROUND Childhood bronchial asthma(BA)is a chronic inflammatory respiratory disease.Nutritional conditions,including zinc deficiency,can affect such allergic disorders.AIM To outline the difference in serum zinc levels between asthmatic children and healthy controls.METHODS A cross-sectional study was carried out at Children’s Hospital,Cairo University,investigating serum zinc levels in children with BA(n=40)and healthy children(n=21).Other markers included serum ferritin,iron,hemoglobin(Hb),and immunoglobulin E(IgE)levels.Independent t-tests and Mann-Whinny tests were used for comparisons.The Kruskal-Wallis test was applied to compare serum ferritin and IgE levels with regard to asthma severity.Spearman's rank correlation was performed to explore the relationship between serum ferritin levels and both iron and Hb levels in asthmatic children.RESULTS Children with BA had higher levels of zinc,yet the difference was not significant(P=0.115).Serum ferritin and IgE levels were significantly higher in asthmatic children(P=0.006 and 0.001,respectively),yet their levels did not differ significantly by severity(P=0.623 and 0.126,respectively).There was a nonsignificant weak correlation between serum ferritin levels and both serum iron and Hb levels.CONCLUSION Serum zinc levels do not seem to differ between asthmatic children and healthy children.Serum ferritin levels may be a marker of asthma control.Serum IgE levels are not markers of asthma severity.
文摘This editorial discusses a case-control study by Ibrahim et al,published in the recent issue of the World Journal of Clinical Pediatrics.Childhood bronchial asthma is a chronic inflammatory respiratory disease.It was found that an increase in oxidative stress leads to a decrease in antioxidants causing oxidative damage to mitochondrial respiratory chain complexes resulting in the inflammation of the airway,hypersecretion of mucus causing a cascade of clinical manifestations ranging from recurrent episodes of coughing,wheezing,and breathlessness to shortness of breath.Since oxidative stress mediates the inflammatory response in asthma,the supplementation of anti-oxidants can be one strategy to manage this disease.Zinc is one such antioxidant that has attracted much attention about asthma and airway inflammation.Zinc is a crucial trace element for human metabolism that helps to regulate gene expression,enzyme activity,and protein structure.Apart from zinc,free serum ferritin levels are also elevated in case of inflammation.Several previous studies found that ferritin levels may also help determine the pathology of disease and predict prognosis in addition to tracking disease activity.However,this study's results were different from the findings of the previous studies and the zinc levels did not show a significant difference between asthmatic children and non-asthmatic children but ferritin levels were significantly high in asthmatic children as compared to the controls.Hence,the possible role of the biochemical nutritional assessment including zinc and ferritin as biomarkers for asthma severity should be assessed in the future.
文摘BACKGROUND Electronic cigarettes(ECs)have been promoted as alternatives to traditional cigarettes.To investigate ECs’effects on respiratory system,especially in patients with respiratory diseases.METHODS We randomly selected 25 smokers with stable moderate asthma and matched them with 25 healthy smokers.All were subjucted to pulmonary function tests(PFTs),impulse oscillometry(IOS),fraction exhaled Nitric Oxide(FeNO),exhaled breathe condensate(EBC)and biomarker measurements before and after vaping one nicotinecontaining EC.RESULTS The increase in FeNO 30 minutes after EC,reflecting airway inflammation,significantly correlated with increase of residual volume(RV),total lung capacity,respiratory impedance at 5 Hz(Z5Hz)and respiratory resistance at 5 and 20 Hz(R5Hz and R20Hz).No significant correlations were found between EBC biomarkers'changes and respiratory mechanics.CONCLUSION This is the first study demonstrating that the changes in airway inflammation caused by EC have direct effects in respiratory mechanics of asthmatic patients.
文摘Background Occupational asthma is a type of asthma caused by exposure to asthma-causing substances in an occupational setting. Its incidence is closely related to the degree of industrial development, but also related to the nature of asthma. In some specific industries, such as workers who are exposed to asthmatic isocyanates for a long time, the incidence of occupational asthma can reach 5%-10%, and the incidence of occupational asthma can even reach 50% or higher among workers engaged in the detergent industry who are in contact with proteolytic enzymes for a long time. Objective To analyze the clinical value of early comprehensive rehabilitation nursing for patients with occupational asthma, methods a total of 48 patients with occupational asthma who were admitted from January 2020 to December 2022 were divided into control group and study group by random number table method The disappearance time of chest tightness and shortness of breath, the disappearance time of wheezing and cough, and the FEV1, forced vital capacity (FVC) and peak expiratory flow (PEF) indexes before and after treatment were compared between the two groups after nursing, the disappearance time of clinical symptoms in the study group was shorter than that in the control group, and the levels of FEV1, FVC and PEF were higher than those in the control group, and the P < 0.05 was significantly improved.
文摘Objective:To observe and explore the value of the combined application of red blood cell distribution width(RDW),platelet distribution width(PDW),and immunoglobulin E(IgE)in the process of clinical diagnosis of children with asthma.Methods:Fifty-five children with suspected asthma were admitted to the hospital from July 2021 to July 2023.They underwent a bronchodilator test upon admission and their RDW,PDW,and IgE were detected.The efficacy of diagnosis with a single indicator(RDW/PDW/IgE)and combined parameters(PDW+PDW+IgE)were compared with the results of the bronchodilator test.Results:49 cases of pediatric asthma were diagnosed by the bronchodilator test.RDW and PDW of asthmatic children were lower than those of non-asthmatic children,while the IgE of asthmatic children was higher than that of non-asthmatic children,and there was a significant difference in the RDW,PDW,and IgE among children with different degrees of asthma severity(P<0.05).The positive rate of the three combined diagnostic tests of RDW,PDW,and IgE was significantly higher than the positive rate of a single-parameter diagnosis(P<0.05).Conclusion:The combination of RDW,PDW,and IgE plays a crucial role in the clinical diagnosis of asthmatic children.These tests further improve the efficiency of clinical diagnosis and help identify the severity of the disease.
文摘Objective:In order to reveal the potential association between intestinal flora and atopic dermatitis with asthma,the study compares the changes in intestinal flora before and after treatment with antibiotics in children and explores the risk factors for the disease development in children.The differences between asthma-controlled children and healthy children were also analyzed to investigate whether there was a correlation between the level of control and intestinal flora in asthmatic children.Methods:367 children with atopic dermatitis and asthma were selected,and the control group was healthy children who did not have other skin diseases.Fecal samples were collected from healthy children and children with asthma,and the intestinal flora was tested at Beijing Nebula Medical Testing Laboratory Co.At the same time,50 children were selected according to the inclusion and exclusion criteria to take amide antibiotics during hospitalization,and stool samples were collected before and after taking antibiotics.Results:The proportion of Gram-positive cocci increased and the proportion of Gram-positive bacilli decreased after the administration of antibiotics in children with atopic dermatitis and asthma(P<0.05),and no significant difference was shown in the gender and age of the children(P>0.05).The proportion of family history of atopic dermatitis with asthma was higher in the experimental group(P<0.05).Conclusion:The use of antibiotics in children with atopic dermatitis with asthma showed a positive correlation with changes in intestinal flora.The use of antibiotics may lead to changes in intestinal flora and increase the risk of atopic dermatitis with asthma.Antibiotic use in infancy and childhood is also recognized as a risk factor for atopic dermatitis with asthma.Therefore,the use of antibiotics should be minimized in preventing and treating atopic dermatitis with asthma.
文摘Bronchial asthma is a chronic respiratory disease that poses a significant threat to the physical and mental health of children globally.Currently,pulmonary rehabilitation is a non-pharmacological intervention that has shown promise in treating chronic respiratory diseases.However,most studies related to pulmonary rehabilitation only focus on chronic conditions such as chronic obstructive pulmonary disease(COPD),lung cancer,and bronchiectasis.Research on bronchial asthma in children is still in the preliminary stages.This article reviews the concept,basic content,and application mode of pulmonary rehabilitation,to provide reference for the clinical research of pulmonary rehabilitation in children with bronchial asthma,and to carry out multimodal pulmonary rehabilitation to improve the disease control level and quality of life of asthma in children.
文摘Objective:To analyze the intervention effect of respiratory care on asthma patients.Methods:49 asthma patients admitted to the hospital between December 1,2018 and November 30,2022 were selected for this study.The patients were divided into Group A(25 cases)and Group B(24 cases).The patients in Group A received respiratory care,while the patients in Group B received routine care,and the nursing effects of both groups were compared.Results:Group A demonstrated a better nursing effect compared to Group B;the patients in Group A were generally more satisfied with the care given compared to those of Group B.Furthermore,Group A showed better improvements in respiratory function compared to Group B(P<0.05).Before care,there was no difference in quality-of-life scores between the two groups(P>0.05).After care,Group A’s quality of life score was lower than Group B’s(P<0.05).Conclusion:Respiratory care for asthma patients can improve the quality of care and patient satisfaction.Besides,it also leads to a better improvement in respiratory function and the quality of life of the patients.
文摘Objective:To study the efficacy of treating pediatric bronchial asthma with a modified Dingchuan Decoction and its effect on inflammatory factors and lung function levels.Methods:Sixty cases of bronchial asthma admitted to the hospital between January and December 2023 were divided into two groups using a computerized randomization method.One group of 30 cases received basic treatment with a salmeterol ticarcoson powder inhaler(control group),while the observation group received the same treatment plus a modified Dingchuan Decoction.The disappearance time of symptoms,levels of inflammatory factors,lung function indexes,and clinical efficacy were compared between the two groups.Results:The disappearance time of symptoms in the observation group was shorter than that in the control group.The levels of inflammatory factors after treatment were lower,and lung function indexes were higher in the observation group compared to the control group.Additionally,the total effective rate of treatment in the observation group was higher than that in the control group(P<0.05).Conclusion:In the clinical treatment of pediatric bronchial asthma,supplementing conventional Western medicine with a modified Dingchuan Decoction is effective,as it actively reduces inflammatory factor levels and improves lung function.

文摘Objective: To investigate the effects of Yanghe Pingchuan Granules on airway remodeling in asthmatic rats, and to explore the mechanism of Interleukin-6/Janus kinase 2/ Signal transducing activator of transcription 3(IL-6/JAK2/STAT3) signal axis. Methods: We separated 42 healthy male SD rats into two groups, a control group (7) and a model group (35).The model group was sensitized with a combination of ovalbumin (OVA) and aluminum hydroxide for 2 weeks, while the control group was given an equal amount of physiological saline.After 2 weeks, the modeling group was randomly divided into Model group, Yanghe Pingchuan Granules high, medium and low dose groups and Dexamethasone group, each group consisted of 7 animals. After 4 weeks, OVA atomization and gavage were used for stimulation and treatment. Yanghe Pingchuan Granules high, middle and low groups were given 15.48, 7.74, 3.87 g∙kg-1 Yanghe Pingchuan Granules daily, dexamethasone group was given 0.0625 mg∙kg-1 dexamethasone daily, and the other groups were given the same amount of normal saline. HE, PAS and Masson staining were used to observe the lung histopathological changes in rats. The levels of interleukin-6, IL-23 and IL-17A were detected by ELISA. The expression levels of JAK-2, P-JAK2, STAT3 and P-STAT3 in lung tissues were detected by Western blot. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the mRNA expression levels of IL-6, JAK2 and STAT3 in rat lung tissue. Results: The lung tissue structure of the model group was severely damaged compared to the control group, accompanied by a great many of inflammatory cell infiltration, goblet cell hyperplasia, subepithelial collagen fiber deposition and airway epithelial thickening were more obvious. The expressions of IL-6, IL- 23 and IL-17A in serum were significantly increased (P<0.01), the protein expression levels of JAK-2, P-JAK2, STAT3 and P-STAT3 and the mRNA expression levels of IL-6, JAK2 and STAT3 in lung tissue were significantly increased (P<0.01);Compared with the model group, inflammatory cell infiltration, goblet cell proliferation, subepithelial collagen fiber deposition and airway epithelial thickening were significantly reduced in each administration group, and the expressions of IL-6, IL-23 and IL-17A in serum were significantly decreased (P< 0.01). The protein expression levels of JAK-2, P-JAK2, STAT3 and P-STAT3 and mRNA expression levels of IL-6, JAK2 and STAT3 in lung tissue were significantly decreased (P<0.01). Conclusion: Yanghe Pingchuan Granules can significantly alleviate airway remodeling in asthmatic rats, and its mechanism may be through inhibiting the IL-6/JAK2/STAT3 signal axis.
