OBJECTIVE: To observe the clinical efficacy of combination therapy of wheat-grained sized cone moxibustion and point-to-point needle insertion with medical ozone penetrating injection for allergic rhinitis (AR) and its effect on inflammation-related indexes. METHODS: Thirty-one patients with persistent AR were enrolled. The patients received medical ozone injection at bilateral Yingxiang (LI20)-to-Shangyingxiang (EX-HN8), and wheat-grained sized cone moxibustion at Dazhui (GV14), twice a week (with a 3-day interval) for 4 consecutive weeks. The total nasal symptoms score (TNSS), total non-nasal symptom score (TNNSS), rhinoconjunctivitis quality of life questionnaire (RQLQ), and rhinitis control assessment test (RCAT) scores were evaluated before treatment, after treatment, and at the 8-week follow-up. Levels of eosinophil (EOS) count, immunoglobulin E (IgE), interleukin (IL)-4, IL-6, and IL-17 were measured before and after treatment. Clinical efficacy was evaluated after treatment, and the recurrence rate was assessed at follow-up. RESULTS: Compared with those before treatment, the TNSS, TNNSS, and RQLQ scores were decreased (P<0.05), while the RCAT score was increased (P<0.05) after treatment and at follow-up. There were no statistically significant differences in above indexes between the post-treatment and follow-up (P>0.05). After treatment, the whole blood EOS count and serum levels of IgE, IL-4, IL-6, and IL-17 were decreased compared with those before treatment (P<0.05). After treatment, 17 cases were markedly effective, 12 cases were effective, and 2 cases were ineffective, resulting in a total effective rate of 93.5%. At follow-up, 2 cases relapsed, and the recurrence rate was 6.9%. CONCLUSION Combination therapy of wheat-grained sized cone moxibustion and point-to-point needle insertion with medical ozone injection can improve AR symptoms, reduce the recurrence rate, and enhance the quality of life. The mechanism may be associated with the regulation of immune-related indexes.

Objective To explore the effect of Evodiamine (Evo) on the immune function of allergic rhinitis (AR) rats and the regulatory mechanism on C-C motif chemokine ligand 2 (CCL2)/ C-C motif chemokine receptor 2 (CCR2) pathway. Methods The related targets of Evo-AR-immune function were screened by network pharmacology, and the protein interaction network diagram of intersecting targets was constructed. The AR rat model was established by ovalbumin (OVA) combined with aluminium hydroxide, and the rats were divided into six groups: a normal control (NC) group, a model group, a Loratadine (LOR) group, an Evodiamine low dose (Evo-L) group, a Evodiamine high dose (Evo-H) groups, and an Evo-H combined with CCL2 group. After the last administration, the symptoms of rats in each group were scored; ELISA was applied to detect the levels of histamine, immunoglobulin E (IgE), interleukin 4 (IL-4), IL-13 and interferon γ (IFN-γ); Diff-Quick staining solution was applied to detecte the number of cells in the nasal lavage fluid (NALF); hematoxylin eosin (HE) staining was applied to observe the pathological changes of nasal mucosa tissue; real-time quantitative PCR was applied to detect the levels of CCL2 and CCR2 mRNA in tissue; Western blot was applied to detect the expression levels of CCL2, CCR2 and CXC motif chemokine ligand 8 (CXCL8) proteins in nasal mucosa. Results There were eight intersection targets of EVo-AR-immune function, and protein interaction network diagram showed that CXCL8 was the core target. Compared with the NC group, the score of nasal symptoms, the levels of histamine, IgE, IL-4 and IL-13, the numbers of eosinophil, macrophages, neutrophils, lymphocytes and total cells, the mRNA and protein expression levels of CCL2 and CCR2, and the expression of CXCL8 protein in the model group were increased, while the level of IFN-γ was decreased. Compared with the model group, the score of nasal symptoms, the levels of histamine, IgE, IL-4 and IL-13, the numbers of eosinophil, macrophages, neutrophils, lymphocytes and total cells, the mRNA and protein expression levels of CCL2 and CCR2, and the expression of CXCL8 protein in LOR and Evo groups were decreased, while the level of IFN-γ was increased. Further use of CCL2 recombinant protein for compensatory experiments revealed that the improvement effect of Evo on immune function in AR rats was reversed by CCL2. Conclusion Evo can improve the immune function of AR rats, and its mechanism may be related to the inhibition of the CCL2/CCR2 pathway.

Objective To mine and analyze the routine blood test data of children with allergic rhinitis (AR), identify routine blood parameters related to childhood allergic rhinitis, establish an effective diagnostic model, and evaluate the performance of the model. Methods This study was a retrospective study of clinical cases. The experimental group comprised a total of 1110 children diagnosed with AR at the First Affiliated Hospital of Air Force Medical University during the period from December 12, 2020 to December 12, 2021, while the control group included 1109 children without a history of allergic rhinitis or other allergic diseases who underwent routine physical examinations during the same period. Information such as age, sex and routine blood test results was collected for all subjects. The levels of routine blood test indicators were compared between AR children and healthy children using comprehensive intelligent baseline analysis, with indicators of P≥0.05 excluded; variables were screened by Lasso regression. Binary Logistic regression was used to further evaluate the influence of multiple routine blood indexes on the results. Five kinds of machine model algorithms were used, namely extreme value gradient lift (XGBoost), logistic regression (LR), gradient lift decision tree (LGBMC), Random forest (RF) and adaptive lift algorithm (AdaBoost), to establish the diagnostic models. The receiver operating characteristic (ROC) curve was used to screen the optimal model. The best LightGBM algorithm was used to build an online patient risk assessment tool for clinical application. Results Statistically significant differences were observed between the AR group and the control group in the following routine blood test indicators: mean cellular hemoglobin concentration (MCHC), hemoglobin (HGB), absolute value of basophils (BASO), absolute value of eosinophils (EOS), large platelet ratio (P-LCR), mean platelet volume (MPV), platelet distribution width (PDW), platelet count (PLT), absolute values of leukocyte neutrophil (W-LCC), leukocyte monocyte (W-MCC), leukocyte lymphocyte (W-SCC), and age. Lasso regression identified these variables as important predictors, and binary Logistic regression further analyzed the significant influence of these variables on the results. The optimal machine learning algorithm LightGBM was used to establish a multi-index joint detection model. The model showed robust prediction performance in the training set, with AUC values of 0.8512 and 0.8103 in the internal validation set. Conclusion The identified routine blood parameters can be used as potential biomarkers for early diagnosis and risk assessment of AR, which can improve the accuracy and efficiency of diagnosis. The established model provides scientific basis for more accurate diagnostic tools and personalized prevention strategies. Future studies should prospectively validate these findings and explore their applicability in other related diseases.

Objective To investigate the expression of blood basophil activation markers in patients with allergic rhinitis (AR) and the effects of allergens on their expression. Methods The blood samples were collected from the following four groups: healthy control (HC), AR patients with negative skin prick test (nAR), seasonal AR patients (sAR) and perennial AR patients (pAR). Flow cytometry was employed to analyze the expression of basophil activation markers Immunoglobulin E receptor I alpha(FcepsilonRIα), CD63 and CD203c in AR patients. Plasma levels of interleukin 4 (IL-4) and IL-8 were measured by liquid-phase chip technology, and their correlations with the percentages of activated basophils were further analyzed. An ovalbumin-induced AR mouse model was established, and the expression levels of FcepsilonRIα and CD63 on blood basophils were detected. Results The expression of FcepsilonRIα, CD203c and CD63 on basophils were increased in nAR, sAR and pAR patients. Allergens enhanced the mean florescence intensity expression of CD63 and CD203c on basophils of sAR and pAR patients. The plasma levels of IL-4 and IL-8 were elevated in nAR, sAR and pAR patients, showing moderate to high correlations with the expression levels of basophil activation markers. The FcepsilonRIαand CD63 expression on basophils of AR mice were increased. Conclusion Allergens may contribute to AR pathogenesis by upregulating the expression of FcepsilonRIα, CD63 and CD203c, as well as promoting the secretion of IL-4 and IL-8.

Objective:To investigate the clinical characteristics and major allergens of patients with pollen-food allergy syndrome（PFAS） and their correlation with the severity of symptoms, and to provide a basis for identifying high-risk patients, optimizing the allergen testing process and developing individualized dietary management strategies. Methods:The clinical data of 166 patients with PFAS admitted to our hospital from January 2021 to July 2023 were retrospectively analyzed. The clinical symptoms, pollen types and food allergy of the patients were analyzed by questionnaire survey and serum specific IgE detection. phi coefficient, Apriori algorithm modeling and multivariate logistic regression analysis were used to evaluate the association between allergen and symptom severity. Results:Artemisia pollen was the most common allergen in this area, with a positive rate of 96.39%. Peach and mango were the most common food allergens, which caused allergic reactions in 24.10% and 22.89% of patients, respectively. Oral mucosal symptoms were the main symptoms. Correlation analysis showed that there was a correlation between pollen allergens and allergenic food. Association rule analysis showed that when the patient was allergic to the combination of peanuts and trees, the probability of high severity of symptoms was 82.35%. Multivariate analysis showed that ragweed allergy was significantly positively correlated with the severity of PFAS symptoms. Conclusion:Artemisia pollen and related food allergens play an important role in the pathogenesis of PFAS. Association rule mining and network map analysis revealed direct associations between peanut and tree combination allergy and symptom severity, as well as potential links between other inhaled allergens and specific food allergies. Ragweed and peach allergy are independent risk factors for the aggravation of PFAS symptoms, which can be used as early warning indicators. These results help to improve the screening of high-risk patients and the construction of regional allergen databases.

OBJECTIVETo investigate the effect of allergic rhinitis (AR) and its intervention on disease condition and medications in patients with juvenile-onset systemic lupus erythematosus (JSLE).

METHODSThe clinical data of 96 children diagnosed with JSLE were collected, and according to the presence or absence of AR or other allergic diseases, they were divided into AR group (n=44), non-AR group (n=20), and non-allergic group (n=32). The children in the AR group were randomly administered with or without intervention (n=22 each). All the children were given standard JSLE treatment. The systemic lupus erythematosus disease active index (SLEDAI) and application of hormones and immunosuppressants were compared between groups.

RESULTSThe AR and non-AR groups had significantly higher SLEDAI scores, daily cumulative doses of glucocorticoids, and number of types of immunosuppressants used than the non-allergic group before treatment (P<0.05), while there were no significant differences between the AR and non-AR groups (P>0.05). After one month of treatment, the AR group with intervention had significantly lower SLEDAI scores and daily cumulative doses of glucocorticoids than the AR group without intervention (P<0.05), while there was no significant difference in the application of immunosuppressants between these two groups (P>0.05). After 3 and 6 months of treatment, the AR group with intervention had significantly lower SLEDAI scores, daily cumulative doses of glucocorticoids, and number of types of immunosuppressants than the AR group without intervention (P<0.05).

CONCLUSIONSJSLE combined with allergic diseases such as AR has an adverse effect on disease condition and treatment, and the intervention for AR helps with the control of JSLE.

OBJECTIVETo investigate the distribution characteristics of serum specific IgE (sIgE) for inhaled allergens in children with different airway allergic diseases.

METHODSFluorescent enzyme-linked immunosorbent assay on the UniCAP250 system was performed to measure serum sIgE for 9 common inhaled allergens in 256 children aged 3-14 years with different airway allergic diseases. According to the clinical diagnosis, these children were divided into rhinitis group (37 children with allergic rhinitis), asthma group (82 children with bronchial asthma), and rhinitis-asthma group (137 children with allergic rhinitis complicated by bronchial asthma). The three groups were compared in terms of the detection rates of 9 inhaled allergens, sensitization level, and number of allergens.

RESULTSThe detection rate of serum sIgE for inhaled allergens was 57.3% (47/82) in the asthma group, 86.5% (32/37) in the rhinitis group, and 82.5% (113/137) in the rhinitis-asthma group (P<0.05). The most common allergen in the asthma, rhinitis, and the rhinitis-asthma groups was mould fungi (32.9%, 54.1%, and 48.9% respectively), followed by dust mites (30.5%, 45.9%, and 46.0% respectively), pollen (26.8%, 35.1%, and 32.8% respectively), pets (12.2%, 27.0%, and 18.2% respectively), and cockroach (9.8%, 5.4%, and 5.8% respectively). The rhinitis group and the rhinitis-asthma group had a significantly higher detection rate of mould fungi (mx2) than the asthma group (P<0.0166). There were no significant differences in the sensitization level of 9 allergens and number of allergens between the three groups.

CONCLUSIONSIn children with either bronchial asthma, allergic rhinitis, or bronchial asthma complicated by allergic rhinitis, the three most common inhaled allergens are mould fungi, dust mites, and pollens. Compared with bronchial asthma, allergic rhinitis may be more closely associated with sensitization by mould fungi. The three common airway allergic diseases have similar distribution characteristics of inhaled allergens.

The treatment of chronic spontaneous urticaria begins with antihistamines; however, the dose required typically exceeds that recommended for allergic rhinitis. Second-generation, relatively non-sedating H1-receptor blockers are typically employed up to 4 times a day. First-generation antihistamines, such as hydroxyzine or diphenhydramine (Atarax or Benadryl), were employed similarly in the past. Should high-dose antihistamines fail to control symptoms (at least 50%), omalizumab at 300 mg/month is the next step. This is effective in 70% of antihistamine-refractory patients. H₂-receptor blockers and leukotriene antagonists are no longer recommended; they add little and the literature does not support significant efficacy. For those patients who are unresponsive to both antihistamines and omalizumab, cyclosporine is recommended next. This is similarly effective in 65%–70% of patients; however, care is needed regarding possible side-effects on blood pressure and renal function. Corticosteroids should not be employed chronically due to cumulative toxicity that is dose and time dependent. Brief courses of steroid e.g., 3–10 days can be employed for severe exacerbations, but should be an infrequent occurrence. Finally, other agents, such as dapsone or sulfasalazine, can be tried for those patients unresponsive to antihistamines, omalizumab, and cyclosporine.

PURPOSE: Japanese hop (Humulus spp.) and mugwort (Artemisia spp.) are notable causes of autumn pollinosis in East Asia. However, Japanese hop and mugwort pollen extracts, which are widely used for the diagnosis, have not been standardized. This study was performed to standardize Japanese hop and mugwort pollen extracts. MATERIALS AND METHODS: Allergen extracts were prepared in a standardized way using locally collected Humulus japonicus and purchased Artemisia vulgaris pollens. The immunoglobulin E (IgE) reactivities of prepared extracts were compared with commercial extracts via IgE immunoblotting and inhibition analyses. Intradermal skin tests were performed to determine the bioequivalent allergy unit (BAU). RESULTS: The IgE reactive components of the extracts via IgE immunoblotting were similar to those of commercial extracts. A 11-kDa allergen showed the strongest IgE reactivity in Japanese hop, as did a 28-kDa allergen in mugwort pollen extracts. Allergenic potencies of the investigatory Japanese hop and mugwort extracts were essentially indistinguishable from the commercial ones. Sums of erythema of 50 mm by the intradermal skin test (SigmaED50) were calculated to be 14.4th and 13.6th three-fold dilutions for Japanese hop and mugwort extracts, respectively. Therefore, the allergenic activity of the prepared extracts was 90827.4 BAU/mg for Japanese hop and 34412 BAU/mg for mugwort. CONCLUSION: We produced Japanese hop and mugwort pollen extracts using a standardized method. Standardized Japanese hop and mugwort pollen extracts will facilitate the production of improved diagnostic and immunotherapeutic reagents.

OBJECTIVETo investigate the regulation of adipose-derived mesenchymal stem cells (ADSC) on helper T cells and regulatory T cells in allergic rhinitis(AR) mouse model and the underlying mechanisms.

METHODSUsing random number table, 60 Balb/c mice were divided into 6 groups (represented by: sensitized/challenged/treated ), they were the experimental group 1(OVA/OVA/high dose ADSC), the experimental group 2(OVA/OVA/low dose ADSC), the experimental group 3(OVA/OVA/PBS), the experimental group 4(OVA/OVA/0), the control group 1(PBS/PBS/0) and the control group 2(0/0/0). The mouse ADSC were isolated and cultured through conventional method, and AR mouse model was built with OVA and aluminum. The mice were injected with high (3×10(6)), low (1×10(6)) ADSC respectively labeled by CM-Dil for 3 consecutive days via tail-vein injection and sacrificed 48 hours later. Finally, levels of IL-4, IL-6, IL-10 and IFN -γ in serum were examined by ELISA; expressions of the four cytokines in spleen were examined by q RT-PCR; migration of ADSC to mouse model nasal mucosa were observed through fluorescence microscope; eosinophil infiltration were observed by the nasal HE staining.

RESULTSMouse ADSC was isolated, cultured and identified successfully. There was significant difference in symptom scores of AR models (compared with 0/0/0 group, P<0.01). The IL-4 and IL-6 levels of OVA/OVA/high ADSC group were significantly lower than OVA/OVA/0 group (group 1: (17.95±7.78), (27.51±5.93) pg/ml; group 4: (56.82±9.12), (70.03±7.22) pg/ml), the IFN-γ and IL-10 levels increased significantly (group 1: (367.74±13.79), (417.10±72.40) pg/ml; group 4: (199.46±11.25), (122.50±15.57) pg/ml) in serum. These differences were statistically significant(P<0.01). Compared with OVA/OVA/low ADSC group, the IL-4 and IL-6 levels decreased significantly (group 1: (17.95±7.78), (27.51±5.93) pg/ml; group 2: (41.57±12.27), (56.21±9.23)pg/ml) of OVA / OVA / high ADSC group, and the IFN-γ and IL-10 increased significantly (group 1: (367.74±13.79), (417.10±72.40)pg/ml; group 2: (281.77±30.41), (203.45±87.10) pg/ml). These differences were statistically significant(P<0.01). At the same time, the corresponding changes observed at the levels of the cytokines' mRNA. ADSC labeled by CM-Dil could migrate to the mouse nasal mucosa. OVA/OVA/high ADSC group showed the more red fluorescence than the OVA/OVA/low ADSC group. The eosinophils in nasal mucosa of the two groups reduced compared with the normal control.

CONCLUSIONADSC injected via tail-vein can migrate to nasal mucosa and play non-specific immune effects, that may to effect the releases of some cytokines then to regulate the Th1/Th2 imbalance and the function of Treg cell, finally that be dose-related in a certain extent.
