OBJECTIVE To analyze the distribution characteristics of allergens in patients with allergic rhinitis(AR)in Ningbo,so as to provide a reference for the scientific and accurate prevention and treatment of AR.METHODS A retrospective collection was performed for 2 329 AR patients with typical clinical symptoms who underwent serum allergen specific immunoglobulin E(sIgE)testing in the Department of Otolaryngology Head and Neck Surgery of the First Affiliated Hospital of Ningbo University from May 2021 to April 2024,and compared the distribution of positive rates of inhaled allergens and ingested allergens in different genders,seasons and ages.RESULTS 1.Among the 2 329 AR patients,the positive rate of sIgE was 55.00%,including 53.20%for inhalation allergens and 10.91%for ingestion allergens;2.The allergens of AR patients in Ningbo were mainly inhaled allergens,and the top 5 were house dust mites(90.16%),dust mites(86.61%),tropical parachus(17.66%),the top 5 allergens of cat hair(9.92%)and dog hair(7.82%)were milk(57.87%),shrimp(30.71%),crab(19.29%),egg white(17.32%)and peanut(9.84%);3.There was a statistically significant difference in the positive rates of sIgE between house dust mites in inhaled allergens and milk,crab and shrimp in ingested allergens among different gender groups(P<0.05);4.There was no significant difference in the positive rate of each allergen among patients of different ages and disease seasons(P>0.05),but 56.44%of AR patients were concentrated in minors,and the positive rate of house dust mites was statistically significant among minors(P<0.05).CONCLUSION The main allergens causing AR in Ningbo are house dust mites and dust mites,and the prevention and control work should be actively carried out,precise allergen-specific immunotherapy should be promoted,and the treatment of juvenile AR patients should be emphasized.

Objective:To investigate the influencing factors of blood glucose fluctuation after surgery for type A aortic dissection in non-diabetic patients.Methods:A total of 109 patients with non-diabetic type A aortic dissection who underwent surgical treatment in Ningbo Medical Center Li Huili Hospital from Dec. 2016 to Mar. 2022 were selected as the research subjects. Logistic regression analysis was used to explore the influencing factors of blood glucose fluctuation in non-diabetic patients with type A aortic dissection surgery, and a nomogram model of blood glucose fluctuation in non-diabetic patients with type A aortic dissection surgery was constructed.Results:Logistic regression analysis showed that BMI≥24 kg/m 2, poor sleep quality, depression, cardiopulmonary bypass time>5 h and intraoperative bleeding were the risk factors for postoperative blood glucose fluctuation in non-diabetic type A aortic dissection patients ( P<0.05). The C-index of the nomogram model was 0.746 (95% CI: 0.711-0.781) ; the calibration curve was in good agreement with the ideal curve; the AUC of the nomogram model was 0.804. Conclusion:BMI≥24 kg/m 2, poor sleep quality, depression, cardiopulmonary bypass time>5 h and intraoperative bleeding are risk factors for postoperative blood glucose fluctuation in non-diabetic type A aortic dissection patients.

Objective:To investigate the effects of desloratadine combined with Tongqiao Biyan capsule on allergic rhinitis. Methods:100 patients with allergic rhinitis who received treatment in The Affiliated Hospital of Medical College of Ningbo University from February 2018 to February 2020 were included in this study. They were randomly assigned to receive treatment with either desloratadine tablets (control group, n = 50) or desloratadine tablets combined with Tongqiao Biyan capsule (observation group, n = 50) for 21 days. Improvement in clinical symptoms and changes in inflammatory factors were observed in each group. Results:Scores of nasal itch, nasal obstruction, runny nose, and sneezing in the observation group were (1.42 ± 0.10) points, (1.20 ± 0.13) points, (1.25 ± 0.13) points, and (1.33 ± 0.14) points, respectively, which were significantly lower than those in the control group [(1.80 ± 0.12) points, (1.68 ± 0.15) points, (1.68 ± 0.11) points, (1.68 ± 0.13) points, t = 17.20, 17.10, 17.85, 12.95, all P < 0.001]. After treatment, interleukin -4, -6, -8 levels in the observation group were (16.12 ± 5.05) ng/L, (5.33 ± 2.10) ng/L, (37.16 ± 9.80) ng/L, respectively, which were significantly lower than those in the control group [(21.52 ± 5.58) ng/L, (8.12 ± 2.15) ng/L, (48.55 ± 9.65) ng/L, t = 5.07, 6.56, 5.86, all P < 0.05]. Interferon-γ level was significantly higher in the observation group than in the control group [(26.58 ± 2.58) ng/L vs. (23.68 ± 2.69) ng/L, t = 5.50, P < 0.001]. After treatment, the total score of the quality of life questionnaire was significantly higher in the observation group than in the control group [(61.58 ± 8.57) points vs. (40.98 ± 8.35) points, t = 12.17, P < 0.001]. There was no significant difference in total incidence of adverse reactions between observation and control groups [10.00% (5/50) vs. 14.00% (7/50), χ2 = 0.38, P > 0.05]. Conclusion:Desloratadine combined with Tongqiao Biyan capsule can better improve the symptoms of allergic rhinitis and better reduce inflammation without increasing adverse drug reactions compared with desloratadine alone.

Objective To investigate the clinical effect of transverse island fasciocutaneous penile flap in the treatment of meatus and navicular fossa stricture.Methods Fifteen patients with urethral reconstruction with transverse island fasciocutaneous penile flap from October 2014 to December 2018 were enrolled.Six patients had a history of urethroscopic surgery,three had a history of lichensclerosus,three had a history of urethral dilation,and three had no obvious causes.All patients underwent transverse incision under the coronal sulcus,and after fully dissecting the urethra,the urethra was opened longitudinally ventrally.After measuring the actual length of stenosis,the irradiance fascia flap with the corresponding length of the incision was reconstructed.The patients were reviewed at 1 and 3 months after operation,and any complications such as recurrence or urinary fistula were recorded.The urine flow rate was tested 3 months after surgery.Results All 15 patients in this group underwent a successfully operation.The actual measurement of urethral stricture length was 0.5-4.0 cm during operation,with the average of 2.82 cm.Three months after the operation,the urine flow rate ranged from 13.5 ml/s to 23.7 ml/s,with an average of 18.5 ml/s.The overall successful rate was 93.3％ (14/15).The rate of post-operative fistula was 20.0％ (3/15).Two cases complained of needle-like fistula at the incision.One case healed after 3 months,and the other gave up further treatment.One patient developed urethral stricture and urethral skin spasm again 1 month later and was surgically repaired again.Conclusions The initial experience of pedicled island fascia flap for the treatment of urethral stenosis and scaphoid stenosis is safe,feasible and effective for the treatment of urethral stricture.

Objective To evaluate the effect of Roux-en-Y gastric bypass on patients with different preoperative glycosylated hemoglobin (HbAlc) level.Methods From Jan.2008 to Dec.2009,54 patients with gastric lesions and type 2 diabetes mellitus were preoperatively divided into 3 groups:group A (HbAlc:6.5％ -7.9％ ),group B ( HbAlc:8.0％ - 9.9％ ),and group C ( HbAlc ＞ 10％ ).They all underwent Roux-en-Y gastric bypass.The fasting plasma glucose(FPG) and HbAlc concentration were measured before surgery and 12,24,48 weeks after surgery.The antidiabetic medication was analyzed before surgery and 48 weeks after surgery.Results FPG and HbAlc concentration decreased significantly after surgery ( P ＜ 0.01 ).FPG and HbAlc concentration differed greatly between the different groups ( P ＜ 0.01 ).With the increase of preoperative HbAlc,FPG and HbAlc concentrations were poorly controlled after surgery.Conclusion Roux-en-Y gastric bypass surgery can effectively improve glucose metabolism for patients with preoperative HbAlc ＜ 10％.
