Objective:To explore the clinical correlation between peripheral blood basophil levels and chronic sinusitis （CRS） subtypes. Methods:One hundred and twenty-six patients with CRS and 103 healthy cases from physical examination admitted to the First Affiliated Hospital of Soochow University from January 2021 to October 2022 were retrospectively analyzed. According to the histopathological classification, CRS patients were divided into eosinophilic chronic sinusitis （eCRS） group （47 cases） and non eosinophilic chronic sinusitis （non-eCRS） group （79 cases）. The differences among the three groups in peripheral blood inflammation cell counts, eosinophils-to-basophils ratio（bEBR）, basophils-to-neutrophils ratio（BNR）, basophils-to-lymphocytes ratio（BLR）, basophils-to-monocytes ratio（BMR） were compared, and study the correlation between each index and Lund-Mackay score, and the correlation between basophils in peripheral blood and other inflammatory cells. Results:The counts of basophils in the peripheral blood of the healthy control group, eCRS group and non-eCRS group were 0.03±0.01, 0.04±0.02, 0.03±0.02, respectively, the eosinophils-to-basophils ratio（bEBR） were 5.64±4.22, 8.38±5.95, 4.55±3.90, the basophils-to-neutrophils ratio（BNR） were 0.01±0, 0.01±0.01, 0.01±0.01, and the basophils-to-lymphocytes ratio（BLR） were 0.01±0.01, 0.02±0.01, and 0.02±0.01, respectively, the basophils-to-monocytes ratio（BMR） were 0.08±0.04, 0.11±0.06, and 0.08 ±0.04 respectively. There was a statistically significant difference between eCRS group and healthy control group, non-eCRS group（P<0.01）, while there was no statistically significant difference between non-eCRS group and healthy control group（P>0.05）. Basophil counts （r=0.185 5, P<0.05）, BLR（r=0.226 9, P<0.05）, BMR（r=0.228 1, P<0.01） in patients with CRS were positively correlated with Lund Makey score. In addition, basophils were also positively correlated with eosinophils（r=0.479 2, P<0.01）, lymphocytes（r=0.259 4, P<0.01）, and monocytes（r=0.256 4, P<0.01） in patients with CRS. Conclusion:The peripheral blood basophil count, BLR and BMR were significantly increased in eCRS, and were significantly positively correlated with Lund -Makey score. It has the potential to develop into disease biomarkers and new therapeutic targets of eCRS.

Objective: To explore the types and clinical characteristics of chronic rhinosinusitis with nasal polyps (CRSwNP) based on artificial intelligence and whole-slide imaging (WSI), and to explore the consistency of the diagnostic criteria of the Japanese epidemiological survey of refractory eosinophilic chronic rhinosinusitis (JESREC) in Chinese CRSwNP patients. Methods: The data of 136 patients with CRSwNP (101 males and 35 females, aging 14 to 70 years) who underwent endoscopic sinus surgery from 2018 to 2019 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analysed retrospectively. The preoperative clinical characteristics of patients were collected, such as visual analogue scale (VAS) of nasal symptoms, peripheral blood inflammatory cell count, total immunoglobulin E (IgE), Lund-Kennedy score and Lund-Mackay score. The proportion of inflammatory cells such as eosinophils, lymphocytes, plasma cells and neutrophils were calculated on the WSI of each patient through artificial intelligence chronic rhinosinusitis evaluation platform 2.0 (AICEP 2.0), and the specific type of nasal polyps was then obtained as eosinophilic CRSwNP (eCRSwNP) or non-eosinophilic CRSwNP (non-eCRSwNP). In addition, the JESREC diagnostic criteria was used to classify the nasal polyps, and the classification results were compared with the current gold standard for nasal polyps diagnosis (pathological diagnosis based on WSI). The accuracy, sensitivity and specificity of the diagnostic criteria of JESREC were evaluated. The data were expressed in M (Q₁, Q₃) and statistically analyzed by SPSS 17.0. Results: There was no significant difference between eCRSwNP and non-eCRSwNP in age distribution, gender, time of onset, total VAS score, Lund-Kennedy score or Lund-Mackay score. However, there was a significant difference in the ratio of nasal polyp inflammatory cells (eosinophils 40.5% (22.8%, 54.7%) vs 2.5% (1.0%, 5.3%), neutrophils 0.3% (0.1%, 0.7%) vs 1.3% (0.5%, 3.6%), lymphocytes 49.9% (39.3%, 65.9%) vs 82.0% (72.8%, 87.5%), plasma cells 5.1% (3.6%, 10.5%) vs 13.0% (7.4%, 16.3%), χ² value was 9.91, 4.66, 8.28, 5.06, respectively, all P<0.05). In addition, eCRSwNP had a significantly higher level of proportion of allergic symptoms (nasal itching and sneezing), asthma, peripheral blood eosinophil and total IgE (all P<0.05). The overall accuracy, sensitivity and specificity of the JESREC diagnostic criteria was 74.3%, 81.3% and 64.3%, respectively. Conclusions: The eCRSwNP based on artificial intelligence and WSI has significant high level of allergic symptoms, asthma, peripheral blood eosinophils and total IgE, and the percentages of inflammatory cells in nasal polyps are different from that of non-eCRSwNP. The JESREC diagnostic criteria has good consistency in our research.

Objective: To compare the clinical characteristics and plasma inflammatory markers levels in different endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP), and to explore the plasma biomarkers associated with endotypes of CRSwNP. Methods: A total of 74 CRSwNP patients (male/female: 41/33; average age: 40 years) and 40 control subjects underwent septoplasty in Tongji Hospital from January 2015 to December 2017 were enrolled in this study. The demographic and clinical features of all subjects including age, gender, past history, visual analogue scale (VAS) and CT scores were recorded. Patients with CRSwNP were divided into Eos^highNeu^high, Eos^highNeu^low, Eos^lowNeu^high and Eos^lowNeu^low four endotypes according to the eosinophil (Eos) percentage and neutrophil (Neu) count of nasal polyps tissue. Preoperative blood routine was performed and the levels of 27 biomarkers in plasma were measured by Bio-Plex suspension chip method. The clinical characteristics and the level of serum biomarkers of patients with different endotypes were compared. SPSS 18.0 software was used for statistical analysis. Results: There was no difference in the clinical features including gender ratio, age, course of disease, VAS score, endoscopy and CT score among Eos^highNeu^high, Eos^highNeu^low, Eos^lowNeu^high and Eos^lowNeu^low CRSwNP patients. Compared with Eos^lowNeu^high and Eos^lowNeu^low CRSwNP patients, patients with Eos^highNeu^high and Eos^highNeu^low endotype demonstrated a higher prevalence of atopy, allergic rhinitis and asthma comorbidity, and increased peripheral blood eosinophil absolute count and percentage (all P<0.05). However, there was no significant difference between Eos^highNeu^high and Eos^highNeu^low CRSwNP. Plasma levels of all 27 mediators including type 1 cytokines (IL-12 and IFN-γ), type 2 cytokines (IL-4, IL-5 and IL-13), type 3 cytokines (IL-17A), pro-inflammatory cytokines (IL-6 and TNF-α) and tissue remodeling-related markers (bFGF, VEGF and PDGF-BB) demonstrated no significant difference among all endotypes of CRSwNP (all P>0.05). Conclusions: Eos^high and Eos^low CRSwNP patients display significant differences regarding the prevalence of atopy, allergic rhinitis and asthma comorbidity, peripheral blood eosinophil absolute count and percentage, but the clinical characteristics, blood cellular and biological markers can not effectively distinguish four endotypes of CRSwNP. Further studies are warranted to dig out the potential objective, convenient and reliable markers associated with endotypes in patients with CRSwNP.

Objective: To investigate the effects of dopamine on olfactory function and inflammatory injury of olfactory bulb in mice with allergic rhinitis (AR). Methods: AR mouse model was established by using ovalbumin (OVA), and the mice were divided into two groups: olfactory dysfunction (OD) group and without OD group through buried food pellet test (BFPT). The OD mice were randomly divided into 2 groups, and OVA combined with dopamine (3, 6, 9 and 12 days, respectively) or OVA combined with an equal amount of PBS (the same treatment time) was administered nasally. The olfactory function of mice was evaluated by BFPT. The number of eosinophils and goblet cells in the nasal mucosa were detected by HE and PAS staining. Western blotting, immunohistochemistry or immunofluorescence were used to detect the expression of olfactory marker protein (OMP) in olfactory epithelium, the important rate-limiting enzyme tyrosine hydroxylase (TH) of dopamine, and the marker proteins glial fibrillary acidic protein (GFAP) and CD11b of glial cell in the olfactory bulb. TUNEL staining was used to detect the damage of the olfactory bulb. SPSS 26.0 software was used for statistical analysis. Results: AR mice with OD had AR pathological characteristics. Compared with AR mice without OD, the expression of OMP in olfactory epithelium of AR mice with OD was reduced (F=26.09, P<0.05), the expression of GFAP and CD11b in the olfactory bulb was increased (F value was 38.95 and 71.71, respectively, both P<0.05), and the expression of TH in the olfactory bulb was decreased (F=77.00, P<0.05). Nasal administration of dopamine could shorten the time of food globule detection in mice to a certain extent, down-regulate the expression of GFAP and CD11b in the olfactory bulb (F value was 6.55 and 46.11, respectively, both P<0.05), and reduce the number of apoptotic cells in the olfactory bulb (F=25.64, P<0.05). But dopamine had no significant effect on the number of eosinophils and goblet cells in nasal mucosa (F value was 36.26 and 19.38, respectively, both P>0.05), and had no significant effect on the expression of OMP in the olfactory epithelium (F=55.27, P>0.05). Conclusion: Dopamine can improve olfactory function in mice with AR to a certain extent, possibly because of inhibiting the activation of glial cells in olfactory bulb and reducing the apoptotic injury of olfactory bulb cells.

Objective: To explore the characteristics of neonatal adenoid development and to study the relationship between neonatal adenoid development and disease. Methods: A retrospective analysis of neonates who received an electronic rhinopharyngolaryngoscope at Shenzhen Children's Hospital from January 2019 to December 2020 was conducted to track the children's medical history and to analyze the adenoid development status. All 131 neonates successfully completed the electronic laryngoscopy. According to the presence or absence of visible adenoid hyperplasia, they were divided into a hyperplasia group (81 cases, 61.83%) and an un-hyperplasia group (50 cases, 38.17%). Results: Compared with the un-hyperplasia group, the age and birth weight of the adenoid hyperplasia group were larger, and the difference was statistically significant (Z _age=-4.634,Z _weight=-2.273,all P<0.05), but there was no significant difference in gender and gestational age between the two groups. The number of neonates with rhinitis/sinusitis in the hyperplasia group were significantly more than those in the un-hyperplasia group (62.96% vs 48%). Conclusion: The development of neonatal adenoids is related to daily age, birth weight, but not significantly related to gender and gestational age.

Objective: To investigate the roles of hypoxic stimulation in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) by comparing the variation and differences of inflammatory factors secreted from epithelial cells of nasal polyps and normal nasal mucosa under hypoxic stimulation. Methods: Sixty-eight patients who were diagnosed with CRSwNP from June 2015 to January 2018 at China-Japan Union Hospital of Jilin University were analyzed, including 36 males and 32 females, aged (45.2±12.5) years. Nasal polyps mucosa was included in CRS-NP group and inferior turbinate mucosa was included in CRS-IT group. According to the degree of eosinophil infiltration in histopathologic results, each of these two groups was further divided into eosinophil infiltration and non-eosinophil infiltration as Eos-NP group (n=34), Non-Eos-NP group (n=34), Eos-IT group (n=20) and Non-Eos-IT group (n=20). The inferior turbinate mucosa of twenty-five patients who were diagnosed with cyst of paranasal sinus or deviation of nasal septum was classified as control group (n=25), including 14 males and 11 females, aged (42.8±10.2) years. The expression of interleukin 17A (IL-17A), interferon γ (IFN-γ), tumor necrosis factor α (TNF-α) and hypoxia-inducible factor 1α (HIF-1α) in each group was analyzed by immunohistochemical staining. After 0, 24 and 48 h hypoxic stimulation, the secretion of IL-17A, IFN-γ, TNF-α in primary nasal mucosa epithelial cells of each group was tested by enzyme-linked immune sorbent assay (ELISA) experiment; the expression of HIF-1α was tested by immunofluorescent staining and imaging and Western blot. SPSS 17.0 software and two-way ANOVA were used for statistical analysis. Results: Immunohistochemical staining showed that the expression of IL-17A and TNF-α was much higher in control group (optical density (OD) value was 0.37±0.03, 0.53±0.02, respectively) and the expression of IFN-γ and HIF-1α was much higher in Eos-IT group (OD value was 0.47±0.03, 0.39±0.02, respectively). The secretion of IL-17A and TNF-α was much lower in control group than that in other groups under normal condition. After 48 h hypoxic stimulation, the secretion of IL-17A and TNF-α was much higher in control group compared with other groups. The secretion of IFN-γ in Eos-NP group was much higher than that in control group under normal condition ((13.7±1.3) pg/ml vs (11.1±1.6) pg/ml, P<0.05). After 48 h hypoxic stimulation, there was no difference of IFN-γ between control group and Eos-NP group. The expression of HIF-1α decreased in Eos-NP group and Non-Eos-NP group while increased in CRS-IT group and control group upon prolonged exposure to hypoxia. HIF-1α was mostly located at cytoplasm of epithelial cells in control and CRS-IT group while mainly located at nucleus of epithelial cells in CRS-NP group. Conclusions: The secretion of IL-17A, TNF-α, IFN-γ and the expression of HIF-1α show significant difference between normal nasal mucosa, polyps and inferior turbinate of CRSwNP under hypoxic stimulation, presenting different subcellular localization. This illustrates the proteins above are involved in transcription and regulation of the gene responsible for the pathogenesis of CRSwNP.

Objective: To identify the differentially expressed genes in nasal epithelial cells from chronic rhinosinusitis with nasal polyps (CRSwNP), and to analyze related genes which are involved in deficiency of nasal epithelial barrier in CRSwNP patients by analyzing the datasets download from the gene expression omnibus(GEO) database. Methods: The mRNA expression microarray data numbered GSE107624 (7 CRSwNP and 7 controls) and GSE69093 (13 CRSwNP and 11 controls) were downloaded from the publicly available GEO database. These two datasets were jointly analyzed to screen the differentially expressed genes in nasal epithelial cells of controls and CRSwNP patients. In the meanwhile, we further evaluated the function annotation and regulatory pathways of the differentially expressed genes. To further confirmed what we have observed, sinus tissues were collected from patients with CRSwNP (14 cases, 46.8±17.9 years) and uncinate process tissues were collected from patients with nasal septum deviation (7 cases, 23.4±2.3 years) as control group. The primary epithelial cells of nasal mucosa were cultured and the mRNA level of screened genes were measured by Q-PCR. SPSS 22.0 software was used to for statistical analysis. Results: GSE107624 dataset showed that there were 3 856 differentially genes in nasal epithelial cells between CRSwNP and control group, while there were 771 differentially expressed genes in GSE69093 dataset. Finally, 55 up-regulated genes and 3 down-regulated genes were noticed in nasal epithelial cells of CRSwNP patients in the two datasets. GO gene functional annotation analysis showed that SPTBN1, FNBP1L, VAPB and SNX1 were involved in cell adhesion function, MAP1B was participated in the formation of microtubule related complex. KEGG pathway enrichment analysis indicated that BAMBI and SIAH1 were involved in regulation of Wnt pathway, COL6A1 and EIF4E were involved in the regulation of PI3K-AKT pathway. String protein interaction network analysis assumed that MAP1B and VAPB were the core functional proteins. Among top 3 differentially expressed genes COL6A1, MAP1B and BAMBI, only MAP1B gene was increased in nasal epithelial cells of CRSwNP patients in comparison to controls. Conclusion: The increased MAP1B gene in epithelial cells of CRSwNP, as well as abnormal regulation of Wnt and PI3K-AKT signal pathways may mediate the barrier dysfunction in CRSwNP.

Objective: To investigate the difference of concentrations of specialized pro-resolving mediators (SPMs) derived from fatty acids in eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP) and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP). Methods: A total of 36 patients with bilateral chronic rhinosinusitis with nasal polyps (CRSwNP) who underwent endoscopic nasal surgeries in Peking Union Medical College Hospital from May 2019 to September 2020 were enrolled, including 27 males and 9 females, with the age from 13 to 67 years. There were 23 cases of ECRSwNP and 13 cases of nECRSwNP. At the same time, 12 control subjects were enrolled. The concentrations of multiple SPMs, including lipoxins (LXA₄ and LXB₄), resolvins (RvD₁, RvD₂, RvD₃, RvD₅ and RvE₁), protectins (PDX) and maresins (Mar-1) in nasal polyps with different histological subtypes and normal nasal mucosa were analyzed using liquid chromatography-tandem mass spectrometry. The concentrations of SPMs between groups were compared using Mann-Whitney U test. Spearman's rank correlation coefficient was used to measure the correlation between the concentrations of SPMs in nasal polyps and tissue eosinophil counts. Results: The concentrations of RvD₂, RvD₃, RvD₅, LXA₄, LXB₄, Mar-1 and PDX in ECRSwNP group were significantly higher than that in controls (Z value was -2.276, -2.313, -3.371, -2.094, -2.051, -3.104 and -2.294, respectively, all P<0.05). The concentrations of RvD₂, RvD₅, Mar-1 and PDX in ECRSwNP group were significantly higher than those in nECRSwNP group (Z value was -2.175, -2.289, -2.243 and -2.124, respectively, all P<0.05). There was no significant difference in all these SPMs between nECRSwNP and controls (all P>0.05). The concentrations of RvD₂, RvD₃, RvD₅, LXB₄, Mar-1 and PDX in nasal polyps correlated positively with tissue eosinophil counts (r value was 0.443, 0.436, 0.371, 0.502, 0.340 and 0.386, respectively, all P<0.05). Conclusions: A varienty of SPMs are elevated in ECRSwNP. Dysregulation of fatty acid metabolism might play an important role in the chronic inflammation of ECRSwNP.

OBJECTIVETo study the clinicopathologic characteristics of IgG4-related sialodacryoadenitis and chronic rhinosinusitis (CRS).

METHODSA total of 13 patients (patient group) were evaluated clinically and biopsy specimens from the lacrimal/salivary glands (n=12) and nasal mucosa (n=8) were reviewed and immunohistochemistry was performed to assess IgG-and IgG4-positive cells. Similarly, nine patients with IgG4-related sialodacryoadenitis without CRS and 10 patients with common CRS were included as controls.

RESULTSThere were 8 male patients and 5 female patients. The age of patients ranged from 32 to 71 years (mean 50.2 years). The patient group had higher serum IgG4 concentration than that of the control group (P<0.05). Lymphoplasmacytic infiltration, lymphoid follicle formation and sclerosis were prominent in lacrimal/salivary glands in both groups; however the magnitude of IgG4-positive plasmacytic infiltration in the patient group was significantly higher than that of the control group (P<0.05). Similarly, evaluation of nasal mucosa revealed greater lymphocytic and plasmacytic infiltration, and lymphoid follicle formation, together with significantly higher amount of IgG4-positive plasma cell infiltration in the patient group compared to the common CRS group (P<0.05).

CONCLUSIONSIgG4-related disease (IgG4-RD) simultaneously involving lacrimal/salivary glands and nasal cavity/paranasal sinuses is rare and characterized by a combination of IgG4-positive plasma cell infiltration involving lacrimal/salivary glands and nasal mucosa along with an increased serum level of IgG4. As a systemic disease, early and accurate diagnosis is therefore of great importance, and unnecessary surgery should be avoided.
