It is found to be good for anti-inflammation. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In our work, the effect of KMCP on allergic rhinitis(AR)induced by ovalbumin(OVA)was investigated. We found that the number of nasal rubbing and sneezing, the eosinophil(EOS)count in the nasal mucosa, and the serum levels of histamine(HIS), OVA-specific immunoglobulin E(OVA-sIgE)and interleukin-4(IL-4)were decreased, and the histopathological changes of nasal mucosa were inhibited. Additionally, the experiments further proved that the KMCP treatment could exert substantial effects on short-chain fatty acids(SCFAs)metabolism in the cecum as well. Overall findings suggest that KMCP could suppress the inflammatory response in AR mice, and serve as a novel curative therapeutic for AR without side effects.展开更多

Modern medicine still lacks effective treatment methods for such diseases. In recent years, clinical cases of children and adolescents have also increased year by year. Objective: In order to provide references for further study and practical treatment on allergic rhinitis, this paper summarized the advances on the treatment of allergic rhinitis by Traditional Chinese Method (TCM) and Western Medicine Method (WMM) in clinical practice and study. Method: Through detailed review and study of literatures, the theory and clinical experiences in TCM, WMM, and integrated treatment of the two were analyzed and summarized. Conclusions: TCM conducts personalized treatment for patients by syndrome differentiation. The main means are to regulate the body’s health Qi and Yang Qi. Drugs, acupuncture, psychology and other means of treatment are all used and the effects of treatment are very well. WMM mainly relieves the infiltration of local inflammatory cells, expands local capillaries, improves nasal permeability and alleviates the occurrence of allergic graduation by using kinds of drugs or surgery. Though both TCM and WMM are effective and have some common characteristics and each has its own characteristics, the combination of TCM and WMM has a good prospect and is more effective and can effectively reduce the adverse reactions of patients, because TCM is to change patients’ own constitution and the starting point of WMM is to eliminate the pathogen.展开更多

Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.展开更多

文摘According to the proportion of 1:1, konjac flour and mulberry leaf powder are compounded into a kind of dietary fiber source(KMCP). It is found to be good for anti-inflammation. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In our work, the effect of KMCP on allergic rhinitis(AR)induced by ovalbumin(OVA)was investigated. We found that the number of nasal rubbing and sneezing, the eosinophil(EOS)count in the nasal mucosa, and the serum levels of histamine(HIS), OVA-specific immunoglobulin E(OVA-sIgE)and interleukin-4(IL-4)were decreased, and the histopathological changes of nasal mucosa were inhibited. Additionally, the experiments further proved that the KMCP treatment could exert substantial effects on short-chain fatty acids(SCFAs)metabolism in the cecum as well. Overall findings suggest that KMCP could suppress the inflammatory response in AR mice, and serve as a novel curative therapeutic for AR without side effects.

文摘Objective:To explore the effect of"Yingxiang-Hegu"on Th1,Th2-related cytokines and[2]transcription factors T-bet and GATA-3 in rats with allergic rhinitis.Methods:Rats were randomly divided into three groups:blank group,model group and acupoint group.The rat model of ovalbumin(OVA)AR was established,and the general condition of the rats was observed and scored.Acupuncture intervention was performed on the acupoint group on the second day after successful modeling,once per day for 20 min for 10 d.After intervention,the general behavior,behavioral score and histomorphological changes of nasal mucosa were observed.Eosinophils(EOS)were counted under microscope after nasal lavage smear staining,and the contents of total IgE,IFN-γ,IL-12,IL-4 and IL-5 in serum were detected by ELISA.Westernblot and IHC were used to detect the protein level and positive protein expression of specific transcription factors T-bet and GATA-3 in rat nasal mucosa.Results:After the establishment of the model,except for the blank group,the behavioral observation scores of rats in the model group and acupoint group were more than 5 points,indicating that the model was successful.After acupuncture intervention on acupoint"Yingxiang-Hegu",the behavioral score of rats in the acupoint group and western medicine group was significantly lower than that in the model group(P<0.05).Microscopic examination showed that the structure of nasal mucosa in the model group was obviously damaged,cilia were arranged discontinuously,uneven,local congestion and swelling,a large number of epithelial cells exfoliated and necrotic,goblet cell proliferation,obvious inflammatory cell infiltration.The pathological degree of nasal mucosa in the pair point group was significantly less than that in the model group.Compared with the model group,the levels of IFN-γ,IL-2 and IL-12 in serum were significantly increased,while IgE,IL-4,IL-5 and IL-6 were significantly decreased,GATA-3 protein and positive expression in nasal mucosa were significantly decreased and T-bet was significantly increased after acupuncture.Conclusion:Acupuncture at"Yingxiang-Hegu"can effectively improve the nasal sensitive symptoms and control nasal inflammation in AR rats.The mechanism may be that acupuncture at Yingxiang-Hegu can up-regulate the expression of T-bet,decrease the level of GATA-3,promote the production of Th1 cytokines and inhibit the synthesis and secretion of Th2 cells,thus restoring the immune balance of Th1 and Th2.
文摘BACKGROUND There are many adverse reactions in the treatment of allergic rhinitis(AR)mainly with conventional drugs.Leukotriene receptor antagonists,glucocorticoids and nasal antihistamines can all be used as first-line drugs for AR,but the clinical effects of the three drugs are not clear.AIM To examine the impact of glucocorticoids,antihistamines,and leukotriene receptor antagonists on individuals diagnosed with AR,specifically focusing on their influence on serum inflammatory indexes.METHODS The present retrospective study focused on the clinical data of 80 patients diagnosed and treated for AR at our hospital between May 2019 and May 2021.The participants were categorized into the control group and the observation group.The control group received leukotriene receptor antagonists,while the observation group was administered glucocorticoids and antihistamines.Conducted an observation and comparison of the symptoms,physical sign scores,adverse reactions,and effects on serum inflammatory indexes in two distinct groups of patients,both before and after treatment.RESULTS Subsequent to treatment,the nasal itching score,sneeze score,runny nose score,nasal congestion score,and physical signs score exhibited notable discrepancies(P<0.05),with the observation group demonstrating superior outcomes compared to the control group(P<0.05).The interleukin(IL)-6,IL-10,tumor necrosis factor-alpha,Soluble Intercellular Adhesion Molecule-1,Leukotriene D4 after treatment were significantly different and the observation group It is better than the control group,which is statistically significant(P<0.05).Following the intervention,the incidence of adverse reactions in the observation group,including symptoms such as nasal dryness,discomfort in the throat,bitter taste in the mouth,and minor erosion of the nasal mucosa,was found to be 7.5%.This rate was significantly lower compared to the control group,which reported an incidence of 27.5%.The difference between the two groups was statistically significant(P<0.05).CONCLUSION Glucocorticoids and antihistamines have obvious therapeutic effects,reduce serum inflammatory index levels,relieve symptoms and signs of patients,and promote patients'recovery,which can provide a reference for clinical treatment of AR.
文摘Background: Allergic rhinitis is a common and high incidence disease in clinic, which has a certain impact on the work, life and social activities of patients. Modern medicine still lacks effective treatment methods for such diseases. In recent years, clinical cases of children and adolescents have also increased year by year. Objective: In order to provide references for further study and practical treatment on allergic rhinitis, this paper summarized the advances on the treatment of allergic rhinitis by Traditional Chinese Method (TCM) and Western Medicine Method (WMM) in clinical practice and study. Method: Through detailed review and study of literatures, the theory and clinical experiences in TCM, WMM, and integrated treatment of the two were analyzed and summarized. Conclusions: TCM conducts personalized treatment for patients by syndrome differentiation. The main means are to regulate the body’s health Qi and Yang Qi. Drugs, acupuncture, psychology and other means of treatment are all used and the effects of treatment are very well. WMM mainly relieves the infiltration of local inflammatory cells, expands local capillaries, improves nasal permeability and alleviates the occurrence of allergic graduation by using kinds of drugs or surgery. Though both TCM and WMM are effective and have some common characteristics and each has its own characteristics, the combination of TCM and WMM has a good prospect and is more effective and can effectively reduce the adverse reactions of patients, because TCM is to change patients’ own constitution and the starting point of WMM is to eliminate the pathogen.
文摘Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction that affects sino-nasal mucosa and is characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness and eyes itching. Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.

文摘Objective:In order to further study allergic rhinitis,the feasibility of the improved method of establishing mouse allergic rhinitis model by OVA combined with aluminum adjuvant was explored.Methods:16 BALB/c mice(SPF grade)were randomly divided into the control group and the OVA model group.In the OVA model group,mice were given intraperitoneal injection of OVA solution for sensitization(100μg/ml)at weeks 1,2,and 3,and each mouse was injected intraperitoneally with 0.2 ml.On the 22nd to 28th days,the mice were given an OVA solution(100 mg/ml)for nasal stimulation,10μl per mouse,and 5μl per nostril for 7 consecutive days.The general behavior,body weight,and survival rate of the mice were observed on days 22-28,respectively.After 15 minutes of challenge on days 25 and 28,the number of sneezing and sniffing within 15 minutes was recorded.On day 29,spleen and thymus indexes of mice were evaluated,and blood was collected from the orbit to isolate serum,the IgE level was measured,and the histological changes of the nasal mucosa of the mice were observed.Results:OVA can cause significant weight loss in mice,and the weight of mice in the OVA model group is significantly lower than that in the control group(P<0.05).On the 25th and 28th days,the number of sneezes in the OVA model group was significantly higher than that in the control group[(19.27±4.89)vs(4.45±1.25);(19.78±4.92)vs(4.52±1.28);P<0.05].The number of nasal scratching in the OVA model group was significantly higher than that in the control group[(23.14±7.17)vs(13.52±7.64);(23.75±7.35)vs(13.60±7.71);P<0.05].The spleen index of the OVA model group was significantly higher than that of the control group[(8.64±1.49)mg/g vs(4.04±0.65)mg/g,P<0.05],and the thymus index of the OVA model group was significantly lower than that of the control group[(0.75±0.54)mg/g vs(1.87±0.65)mg/g,P<0.05].The IgE level of the OVA model group were significantly higher than that of the control group[(932.86±352.34)μg/ml vs(99.82±0.97)μg/ml,P<0.05].The nasal mucosal tissue lesions in the model group were obvious.Conclusion:In this experiment,a modified OVA-aluminum adjuvant was used to successfully establish the mice model of allergic rhinitis.
文摘<strong>Background:</strong> Rhinopathy, a dysfunction or inflammation of the nasal mucosal lining, presents with symptoms of nasal obstruction, posterior and anterior rhinorrhea, sneezing, nasal itching, and hyposmia, with variations in symptom intensity in each subtype. Asthma originates from a combination of genetic and environmental factors. <strong>Objective:</strong> This study aimed to treat allergic rhinitis in patients with controlled asthma and to verify the behavior of the variables. <strong>Methods:</strong> In this prospective study, quantitative and qualitative assessment of rhinopathy in asthma was performed. Patients with symptoms of rhinopathy and controlled asthma, who were controlled with treatment at the pulmonology outpatient clinic of the Center for Medical Specialties at [hospital], were included. Patients were treated for 2 months according to the IV Rhinopathy Consensus. They underwent a pulmonary function test and completed a questionnaire before and after treatment for rhinopathy. <strong>Results:</strong> In total, 47 patients aged 7 - 12 years (9.30 ± 1.70 years;median 9 years) were evaluated, including 29 (61.7%) males and 18 (38.3%) females. Patients were evaluated at two timepoints, with an interval of 12 days to 14 months (3.81 ± 3.21 months;median 3 months), and were evaluated regarding the various characteristics of their allergy. <strong>Conclusion: </strong>The treatment of allergic rhinitis in patients with asthma resulted in an improvement in variables related to nasal congestion, rhinorrhea, cough, dyspnea, wheezing, and dyspnea on exertion, and maintaining physical activities without dyspnea.

文摘Objective:As a traditional herbal formula,Mahuang Xixin Fuzi decoction(MXFD)has been used to treat allergic rhinitis(AR).It regulates the transcription factor GATA3 in T cells,blocks Th2 skewing and rebalances the Th1/Th2 immunity.Type 2 innate lymphoid cells(ILC2s)are closely associated with GATA3.However,it remains unknown whether ILC2s could be one mechanism through which MXFD acts.We sought to elucidate the efficacy and mechanism of action of this decoction in AR treatment.Methods:Forty C57BL/6J female mice were equally divided into control,model,loratadine-and MXFDtreated groups in random.AR was induced by ovalbumin(OVA),and then treatment with loratadine or MXFD was administered.AR scores were evaluated and compared before and after treatment.Pathological changes in the nasal mucosa and lung were observed using hematoxylin-eosin staining of tissue samples.Activation of ILC2 in nasal mucosa was assessed by immunofluorescence and quantitative polymerase chain reaction analysis.ILC2 cell count in lungs was measured by flow cytometry and levels of interleukin-(IL)4,IL-5 and IL-13 in serum were detected by ELISA.Results:The decoction alleviated the symptoms of AR in mice,improved vascular congestion and expansion,glandular hyperplasia and inflammatory cell infiltration in mouse nasal mucosa and slowly improved the interstitial pneumonia and lesions.Meanwhile,MXFD reduced the number and percentage of ILC2s in the nasal mucosa and lungs,downregulated the expression of GATA3 mRNA and RORa mRNA,and reduced the related inflammatory cytokine levels,including IL-4,IL-5 and IL-13.Conclusion:These data suggest that inhibition of ILC2s by MXFD may be an important means by which to treat AR.
文摘[Objectives]To explore the effect and possible mechanism of bergenin in relieving allergic rhinitis(AR)in mice.[Methods]50 C57/BL6 mice were randomly divided into blank group(n=10),model group(n=10)and high(100 mg/kg),medium(50 mg/kg)and low(25 mg/kg)dose bergenin groups with 10 mice in each group.Except for the blank group,the other mice were sensitized by basic ways combined with attack to replicate the AR model.From the 15th d of modeling(from the second d after the end of the basic modeling),the drug group was given bergenin orally for 15 d,and the blank group and model group were given the same volume of normal saline once a day.24 h after the last establishment of the model,the content of interleukin 4(IL-4),IL-6,TNF-αand IL-1βin nasal lavage fluid and serum of mice in each group was detected by ELISA.The expression of TLR-4,NF-κB and p-NF-κB in nasal mucosa of mice was detected by Western blot.[Results]Compared with the blank group,the content of inflammatory factors IL-4,IL-6,TNF-αand IL-1βin nasal lavage fluid and serum of model group was significantly increased,and the protein expression of TLR-4 and p-NF-κB was significantly increased.After the intervention of bergenin,the content of IL-4,IL-6,TNF-αand IL-1βin nasal lavage fluid and serum and TLR-4 and p-NF-κB protein in tissue was significantly inhibited in bergenin group.[Conclusions]Bergenin can effectively reduce allergic inflammation in AR model mice,and its mechanism may be related to inhibition of inflammation and down-regulation of TLR-4/NF-κB signal pathway.
