Except for the blank group, each mouse in the other groups was intraperitoneally injected with 1 mL of a mixture of 50 μgOVA+5 mg [Al(OH)_(3)] +1 mL of normal saline for 14 d. The allergic rhinitis mouse model was successfully established by intranasal instillation of 5% OVA solution on both sides (20 μL per side, once a day) from the 15 th day after stimulation for 7 d. The blank group was treated with the same amount of saline as above. The volatile oil of Centipeda Herba was obtained by steam distillation and petroleum ether extraction, and then was made into 1.25%, 2.5% and 5% volatile oil of Centipeda Herba with 75% alcohol. The control group was stimulated once every other day with reagent 2 after 7 d of stimulation (maintenance) until the end of treatment. The blank group was treated with 5 mL saline by nasal sniffing for 30 d, twice in the morning and evening, 30 min each time. The alcohol treatment group was treated with 5 mL of 75% alcohol, and the low concentration group, the medium concentration group and the high concentration group were treated with 5 mL of 1.25%, 2.5% and 5% Centipeda Herba volatile oil, respectively. The treatment time was the same as that of the blank group, and the treatment process was carried out in their respective closed contamination boxes. Before and after the treatment, the frequency of sneezing, the frequency of scratching nose, the amount of nasal discharge, activity and other general characteristics of the mice were observed, and the allergic behavior score was carried out. Besides, the IgE content in the serum of the mice was determined, and the eosinophils in the nasal discharge were counted.[Results] The scores of mice before and after treatment showed that there was no significant difference in the alcohol treatment group before and after treatment ( P >0.05), and there was significant difference in the low, medium and high concentration groups before and after treatment ( P <0.05), except that there was no significant difference between the control group and the alcohol treatment group ( P >0.05), and there was significant difference among the other groups ( P <0.05). The levels of IgE and the number of eosinophils in peripheral serum of mice in the control group, alcohol treatment group, low concentration group, medium concentration group and high concentration group were higher than those in the blank group ( P <0.05), and there was no significant difference between the two groups ( P >0.05).[Conclusions] Volatile oil of Centipeda Herba can be used to treat allergic rhinitis by nasal sniffing, and 5% volatile oil of Centipeda Herba has the best effect. During the treatment, sneezing and runny nose in mice were reduced. The results showed that nasal sniffing was less irritating to the nasal cavity and not easy to produce discomfort, the utilization rate of drugs was higher than that of traditional therapy, and the volatile oil could be preserved longer than that of traditional Chinese medicine.展开更多

The distribution and prevalence of allergen-specific IgE (sIgE) play a crucial role in understanding the pathophysiology and management of AR. In Shenzhen, the profile of common allergens in children with AR has not been extensively studied, particularly in relation to seasonal variations, gender, and age differences. Objective: To investigate the distribution of allergen-specific IgE (sIgE) in children with allergic rhinitis (AR) in Shenzhen, focusing on 28 allergens. Methods: A total of 3901 children with AR, aged 0 to 14 years, were selected from the outpatient clinic of Longgang District Maternal and Child Health Hospital. The distribution of sIgE positivity across 28 allergens was compared by season, gender, and age group. Results: Among inhalant allergens, the three most common with the highest positive rates were house dust mites, dog dander, and cat dander. In the food allergen group, the top three were milk, egg white, and beef. Dust mites exhibited the highest positive rate across all four seasons. Statistically significant differences (P P P P P Conclusion: House dust mites and dog dander are the most prevalent inhalant allergens for children with AR across all seasons, genders, and age groups in Shenzhen. Milk and egg white are the primary food allergens. The positive rate for inhalant allergens generally increases with age, while food allergens such as milk and egg white show a decreasing trend. Milk retains a relatively higher positive rate beyond 3 years of age, accompanied by a higher proportion of strong positive sensitization.展开更多

Eighteen BALB/c mice were divided into three groups; the ovalbumin （OVA）-sen- sitized/challenged group, which received saline orally for 6 weeks （OVA group）, the OVA-sensitized/challenged group, which received LFK orally for 6 weeks （LFK-fed group）, and the non-sensitized group, which received saline for 6 weeks （saline control group）. Nasal rubbing and sneezing were monitored during the study. After the final challenge, interleukin （IL）-4, interferon （IFN）-y, and OVA-specific IgE levels in the sera and splenocyte culture supernatants were determined, eosinophilic infiltrate into the upper airway was quantified, and splenic CD4~CD25＋ regulatory T cells （Tregs） were examined by flow cytometry. We found that nasal rubbing was sig- nificantly reduced in LFK-fed mice compared to the OVA group on d 27 and 35, and sneezing was significantly inhibited by LFK administration for 35 d. LFK-fed mice had significantly less eosinophil influx into the nasal mucosa than the OVA group. There were no significant differences between the LFK-fed group and OVA group in the serum and splenocyte culture supernatant levels of IL-4, IFN-y, and OVA-specific IgE. Interestingly, the LFK-fed mice had a significantly greater percentage of splenic CD4＋CD25＋ Tregs than OVA group. Our results indicate that oral administration of LFK may alleviate nasal symptoms, reduce nasal eosinophilia, and increase the percentage of CD4＋CD25＋ Tregs in experimental allergic rhinitis.展开更多

METHODS： This multicenter, randomized, con- trolled clinical trial on PER will be conducted at three institutions in China. The total study period will be 9 weeks. After a 1-week preparatory screen- ing period, 240 eligible participants with PER willbe randomized to receive acupuncture or pharma- cotherapy （1： 1） for 4 weeks with a 4-week fol- low-up. The primary outcome will be changes in 7-day average total nasal symptom score. Second- ary outcome measures include rhinoconjunctivitis quality of life questionnaire score and total non-na- sal symptom score. RESULTS： The presence and seriousness of psycho- logical and emotional impairments should be con- sidered in therapeutic programs for allergic rhinitis. No clinical trial for treating allergic rhinitis via acu- puncture regulation of psychological and emotion- al activities has been reported. CONCLUSION： The findings of the trial will allow us to determine the effects of the mind （Shen）-regula- tion treatment approach. We will also be able to confirm if the effects of acupuncture are equivalent to those of the conventional drug cetirizine hydro- chloride.展开更多

文摘OBJECTIVE:To explore the correlation between acupuncture treatment for allergic rhinitis(AR) and hypothalamic-pituitary-adrenal(HPA) axis regulation by investigating changes in serum immune factors,HPA axis-associated hormone levels,activation levels of paraventricular nucleus(PVN) neurons,and the severity of nasal mucosal lesions,in rats with AR before and after acupuncture treatment.METHODS:After establishing the AR rat model,ovalbumin was administered via nasal drip to all groups except the blank control.Each group received continuous treatment for 14 d:the acupuncture,acupuncture + RU-486(mifepristone),and RU-486 groups received acupuncture only,RU486 intraperitoneal injection and acupuncture,and RU-486 intraperitoneal injection only,respectively.Following the intervention period,behavioral scoring was performed on all AR rats,and peripheral blood,nasal mucosa samples,and brains tissue(containing PVN region) were obtained following euthanization.Interleukin(IL-4,IL-5,IL-13),interferon gamma(IFN-γ),corticosterone(CORT),and corticotrophin-releasing hormone(CRH) levels were evaluated in peripheral blood samples.Adrenocorticotropic hormone(ACTH) levels were determined using an enzyme-linked immunoassay assay,and hematoxylin and eosin staining was performed on the nasal mucosa samples.The expression levels of c-Fos in PVN neurons following acupuncture treatment were evaluated by immunofluorescent staining.RESULTS:Following the intervention period,the behavioral scores for the blank control group were lower than those of other groups(P < 0.05),while the acupuncture group scores were lower than those in the model control,acupuncture + RU486,and RU486 groups(P < 0.05).The blank control group had lower serum IL-4,IL-5,and IL-13 levels than those in the other groups(P < 0.05).The acupuncture group had lower serum IL-4,IL-5,and IL-13 levels than those in the model control,acupuncture + RU486,and RU486 groups(P < 0.05).The blank control group had the highest serum IFN-γ levels among all groups,followed by the acupuncture group.The serum CORT,CRH,and ACTH levels in the blank control group were lower than those in the remaining groups(P < 0.05).These biomarker levels were also lower in the acupuncture group than those in the model control,acupuncture + RU486,and RU486 groups(P < 0.05).Compared with model,rats in the acupuncture group exhibited an increased c-Fos expression in PVN neurons.CONCLUSION:Acupuncture can alleviate AR symptoms and regulate serum inflammatory factor levels and HPA axis-related hormones in AR rats.Moreover,these effects are inhibited by glucocorticoid antagonists,suggesting that acupuncture may regulate AR symptoms through HPA axis regulation.
文摘Vitamin D,beyond its classical role in calcium homeostasis,has emerged as a key regulator of immune function and epithelial barrier integrity.Its deficiency during early childhood—a critical period for immune maturation—has been increasingly implicated in the development of atopic diseases.While extensively studied in asthma,its role in non-respiratory allergic conditions such as atopic dermatitis(AD)and allergic rhinitis(AR)remains comparatively underexplored.This minireview synthesizes current mechanistic and clinical evidence on vitamin D in pediatric AD and AR.In AD,vitamin D promotes epidermal barrier function through upregulation of filaggrin and ceramide synthesis,and enhances antimicrobial defense via induction of antimicrobial peptides.Observational studies consistently report lower serum 25-hydroxyvitamin D in affected children,particularly those with allergic sensitization.Select randomized controlled trials suggest clinical improvement with supplementation,especially at doses>2000 IU/day in deficient individuals.In AR,epidemiological data indicate stronger inverse associations with seasonal(pollen-induced)disease.Proposed mechanisms include modulation of dendritic cells,regulatory T cells,T helper 2 cytokines,and mucosal barrier integrity.The shared immunopathogenesis of AD and AR underscores vitamin D’s relevance.Although promising,clinical evidence remains heterogeneous.Future research should prioritize phenotype-stratified trials to clarify optimal dosing,timing,and individual response determinants,including genetics and microbiome composition.

文摘[Objectives] To explore the efficacy of different concentrations of Centipeda Herba volatile oil in the treatment of allergic rhinitis (AR) by nasal sniffing and the optimal drug concentration.[Methods] Forty-eight mice were randomly divided into control group, blank group, alcohol treatment group, low concentration group, medium concentration group and high concentration group, with 8 mice in each group. Except for the blank group, each mouse in the other groups was intraperitoneally injected with 1 mL of a mixture of 50 μgOVA+5 mg [Al(OH)_(3)] +1 mL of normal saline for 14 d. The allergic rhinitis mouse model was successfully established by intranasal instillation of 5% OVA solution on both sides (20 μL per side, once a day) from the 15 th day after stimulation for 7 d. The blank group was treated with the same amount of saline as above. The volatile oil of Centipeda Herba was obtained by steam distillation and petroleum ether extraction, and then was made into 1.25%, 2.5% and 5% volatile oil of Centipeda Herba with 75% alcohol. The control group was stimulated once every other day with reagent 2 after 7 d of stimulation (maintenance) until the end of treatment. The blank group was treated with 5 mL saline by nasal sniffing for 30 d, twice in the morning and evening, 30 min each time. The alcohol treatment group was treated with 5 mL of 75% alcohol, and the low concentration group, the medium concentration group and the high concentration group were treated with 5 mL of 1.25%, 2.5% and 5% Centipeda Herba volatile oil, respectively. The treatment time was the same as that of the blank group, and the treatment process was carried out in their respective closed contamination boxes. Before and after the treatment, the frequency of sneezing, the frequency of scratching nose, the amount of nasal discharge, activity and other general characteristics of the mice were observed, and the allergic behavior score was carried out. Besides, the IgE content in the serum of the mice was determined, and the eosinophils in the nasal discharge were counted.[Results] The scores of mice before and after treatment showed that there was no significant difference in the alcohol treatment group before and after treatment ( P >0.05), and there was significant difference in the low, medium and high concentration groups before and after treatment ( P <0.05), except that there was no significant difference between the control group and the alcohol treatment group ( P >0.05), and there was significant difference among the other groups ( P <0.05). The levels of IgE and the number of eosinophils in peripheral serum of mice in the control group, alcohol treatment group, low concentration group, medium concentration group and high concentration group were higher than those in the blank group ( P <0.05), and there was no significant difference between the two groups ( P >0.05).[Conclusions] Volatile oil of Centipeda Herba can be used to treat allergic rhinitis by nasal sniffing, and 5% volatile oil of Centipeda Herba has the best effect. During the treatment, sneezing and runny nose in mice were reduced. The results showed that nasal sniffing was less irritating to the nasal cavity and not easy to produce discomfort, the utilization rate of drugs was higher than that of traditional therapy, and the volatile oil could be preserved longer than that of traditional Chinese medicine.

文摘[Objectives]To explore a new method for induction of allergic rhinitis in mice,and compare and evaluate it with common modeling methods.[Methods]36 mice were randomly divided into the control group,blank group and experimental group,and there were 12 mice in each group.The mice in the control group were conventionally induced.That is,the mice were first injected intraperitoneally with the mixture composed of OVA 50μg,[Al(OH)3]5 mg and 1ml of normal saline once every other day,and then since the 15 th d,20μL of 5%OVA solution was dropped into each nasal cavity once a day,which lasted for 7 d.The blank group was treated with the same amount of normal saline according to the control group,and received intraperitoneal injection and bilateral nasal drip respectively.In the experimental group,mice were first given intraperitoneal injection of the mixture composed of ovalbumin(OVA)75μg,aluminum hydroxide gel[Al(OH)3]8 mg and normal saline 1.5 mL for basic sensitization.On the 26 th d,20μL of 3%OVA solution was dropped into each nasal cavity once a day,which lasted for 10 d.The number of sneezes,the number of nose scratching,the amount of nasal discharge,and the activity of mice in each group were observed,and the behavior of allergic reaction was scored.Meanwhile,the number of eosinophils in the nasal discharge of mice and the IgE content in serum were measured.[Results]The score of nasal stimulation symptoms,the number of eosinophils and serum IgE level of mice in the control group and the experimental group were higher than those in the blank group(P<0.05),and there was no statistical significance between the two groups in the three indicators(P>0.05).[Conclusions]The modeling method was more suitable for the development of allergic rhinitis patients condition,and reduced the probability of death of mice due to modeling,and simplified the experimental operation.
文摘BACKGROUND While the efficacy of medications such as fluticasone furoate(FF),fluticasone propionate(FP),and azelastine-fluticasone(AF)has been substantiated in comparison to their respective placebo controls,uncertainties persist regarding the comparative effectiveness of different intranasal agents.AIM To evaluate the efficacy of FP,FF,and AF in the treatment of adult patients with seasonal allergic rhinitis(SAR)using a meta-analytic approach.METHODS A computer search was conducted in Cochrane Library,PubMed,and EMBASE databases to identify randomized controlled trials assessing the effectiveness and safety of FF,FP,and AF in treating SAR.Data on treatment safety and efficacy were extracted and analyzed through meta-analysis.RESULTS A total of 20 studies were included,comprising 10590 participants.The results of the direct meta-analysis indicated that,compared to placebo,both relative Total Nasal Symptom Score(rTNSS)and relative Total Ocular Symptom Score(rTOSS)significantly decreased post-intervention[mean difference(MD)=-1.48,95%confidence interval(CI):-1.73 to-1.22;MD=-0.66,95%CI:-0.82 to-0.49],with similar findings observed across the FF,FP,and AF subgroups.The network meta-analysis results showed that for improving rTNSS and rTOSS,the SUCRA values ranking from highest to lowest were AF,FP,FF,and placebo.Improvements in rTNSS and rTOSS with FP,FF,and AF were all significantly greater than those observed with placebo,with AF demonstrating superior efficacy compared to both FP and FF.No statistically significant difference in rTNSS improvement was found between FP and FF,although FP exhibited significantly greater improvement in rTOSS compared to FF.CONCLUSION In adult patients with SAR,the combination of azelastine and fluticasone shows a significant effect in improving nasal and ocular symptoms,with FP demonstrating marked improvement in ocular symptoms compared to FF.
文摘Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mediated mainly by immunoglobulin E (IgE) in atopic individuals after exposure to allergens, with the typical symptoms of paroxysmal sneezing, watery runny nose, itchy nose and nasal congestion. Mendelian randomization (MR), an innovative epidemiological approach that uses common genetic variants as instrumental variables for exposure, thus enabling prediction of their causal relationship with outcomes, has been widely used in recent years in studies related to AR. This paper provides a review of the method and its progress in the field of allergic rhinitis research.
文摘Background: Allergic rhinitis (AR) is a common allergic disease in children, characterized by an immune response to various environmental and food allergens. The distribution and prevalence of allergen-specific IgE (sIgE) play a crucial role in understanding the pathophysiology and management of AR. In Shenzhen, the profile of common allergens in children with AR has not been extensively studied, particularly in relation to seasonal variations, gender, and age differences. Objective: To investigate the distribution of allergen-specific IgE (sIgE) in children with allergic rhinitis (AR) in Shenzhen, focusing on 28 allergens. Methods: A total of 3901 children with AR, aged 0 to 14 years, were selected from the outpatient clinic of Longgang District Maternal and Child Health Hospital. The distribution of sIgE positivity across 28 allergens was compared by season, gender, and age group. Results: Among inhalant allergens, the three most common with the highest positive rates were house dust mites, dog dander, and cat dander. In the food allergen group, the top three were milk, egg white, and beef. Dust mites exhibited the highest positive rate across all four seasons. Statistically significant differences (P P P P P Conclusion: House dust mites and dog dander are the most prevalent inhalant allergens for children with AR across all seasons, genders, and age groups in Shenzhen. Milk and egg white are the primary food allergens. The positive rate for inhalant allergens generally increases with age, while food allergens such as milk and egg white show a decreasing trend. Milk retains a relatively higher positive rate beyond 3 years of age, accompanied by a higher proportion of strong positive sensitization.

文摘In the current study, we sought to investigate whether lysed Enterococcus faecalis FK-23 （LFK）, a heat-killed probiotic preparation, attenuated eosinophil influx into the upper airway and had immunomodulatory activity in a murine allergic rhinitis model. Eighteen BALB/c mice were divided into three groups; the ovalbumin （OVA）-sen- sitized/challenged group, which received saline orally for 6 weeks （OVA group）, the OVA-sensitized/challenged group, which received LFK orally for 6 weeks （LFK-fed group）, and the non-sensitized group, which received saline for 6 weeks （saline control group）. Nasal rubbing and sneezing were monitored during the study. After the final challenge, interleukin （IL）-4, interferon （IFN）-y, and OVA-specific IgE levels in the sera and splenocyte culture supernatants were determined, eosinophilic infiltrate into the upper airway was quantified, and splenic CD4~CD25＋ regulatory T cells （Tregs） were examined by flow cytometry. We found that nasal rubbing was sig- nificantly reduced in LFK-fed mice compared to the OVA group on d 27 and 35, and sneezing was significantly inhibited by LFK administration for 35 d. LFK-fed mice had significantly less eosinophil influx into the nasal mucosa than the OVA group. There were no significant differences between the LFK-fed group and OVA group in the serum and splenocyte culture supernatant levels of IL-4, IFN-y, and OVA-specific IgE. Interestingly, the LFK-fed mice had a significantly greater percentage of splenic CD4＋CD25＋ Tregs than OVA group. Our results indicate that oral administration of LFK may alleviate nasal symptoms, reduce nasal eosinophilia, and increase the percentage of CD4＋CD25＋ Tregs in experimental allergic rhinitis.

文摘OBJECTIVE： To compare the efficacy of an acu- puncture regimen for persistent allergic rhinitis （PER）, aimed at improving a patient＇s mind or Shen in Traditional Chinese Medicine, to that of a sec- ond-generation H-receptor antagonist, cetirizine hydrochloride. METHODS： This multicenter, randomized, con- trolled clinical trial on PER will be conducted at three institutions in China. The total study period will be 9 weeks. After a 1-week preparatory screen- ing period, 240 eligible participants with PER willbe randomized to receive acupuncture or pharma- cotherapy （1： 1） for 4 weeks with a 4-week fol- low-up. The primary outcome will be changes in 7-day average total nasal symptom score. Second- ary outcome measures include rhinoconjunctivitis quality of life questionnaire score and total non-na- sal symptom score. RESULTS： The presence and seriousness of psycho- logical and emotional impairments should be con- sidered in therapeutic programs for allergic rhinitis. No clinical trial for treating allergic rhinitis via acu- puncture regulation of psychological and emotion- al activities has been reported. CONCLUSION： The findings of the trial will allow us to determine the effects of the mind （Shen）-regula- tion treatment approach. We will also be able to confirm if the effects of acupuncture are equivalent to those of the conventional drug cetirizine hydro- chloride.

文摘Antibiotic exposure-induced dysbiosis of the intestinal flora increases the risk of developing allergic rhinitis.Hence,regulating the balance of intestinal flora may be useful for preventing and treating allergic rhinitis.However,the underlying mechanism is unclear.Dendrobium nobile(Shihu)exhibits anti-inflammatory and immune activities.Hence,in this study,we investigated the mechanism via which Shihu may improve allergic rhinitis.Mouse models of allergic rhinitis with intestinal flora dysbiosis(Model-D,antibiotics induce intestinal flora dysbiosis with ovalbumin-induced allergy)and normal intestinal flora with allergic rhinitis(Model-N,ovalbumin-induced allergy)were established.The effect of Shihu on intestinal flora and inflammation caused during allergic rhinitis were analyzed.Allergic symptoms,infiltration of hematoxylin and eosin in the lungs and nose,and the release of various factors[interleukin(IL)-2,IL-4,IFN-y,IL-6,IL-10,and IL-17]in the lungs were evaluated.The results indicate that intestinal flora dysbiosis exacerbated lung and nose inflammation in allergic rhinitis.However,treatment with the Shihu extract effectively reversed these symp-toms.Besides,the Shihu extract inhibited the PI3K/AXT/mTOR pathway and increased the level of Forkhead box protein in the lungs.Additionally,the Shihu extract reversed intestinal flora dysbiosis at the phylum and genus levels and improved regulator T cell differentiation.Furthermore,in the Model-D group,the Shihu extract inhibited the decrease in the diversity and abundance of the intestinal flora.Screening was performed to determine which intestinal flora was positively correlated with Treg differentiation using Spearman5 s correlation analysis.In conclusion,we showed that Shihu extract restored the balance in intestinal flora and ameliorated inflammation in the lungs of allergic rhinitis mice and predicted a therapeutic new approach using Traditional Chinese Medicine to improve allergic rhinitis.
