Abstract
Objective: To investigate the clinical and pathological features, treatments and prognosis of laryngeal neuroendocrine carcinoma (LNEC). Methods: We conducted the retrospective analysis of the clinical data of 12 patients with LNEC admitted to the Department of Otorhinolaryngology Head and Neck Surgery, Second Hospital of Shanxi Medical University from May 2014 to December 2021, including 9 males and 3 females, aged 50-77 years. There were 4 cases of typical carcinoid tumour (highly differentiated), 5 cases of atypical carcinoid tumour (moderately differentiated) and 3 cases of neuroendocrine small cell carcinoma (hypofractionated). The clinical features, diagnosis, treatment and prognosis of LNEC were analysed. Results: The clinical manifestations of LNEC varied according to the tumour type but did not correlate with the pathological types. The supraglottic type was characterized by sore throat, foreign body sensation in the pharynx, coughing, obstructive sensation when eating and choking on water. The treatments were determined according to the pathological types, lesion location and invasion scope. Of 12 patients 4 underwent horizontal partial laryngectomy plus elective lymphatic dissection plus postoperative radiotherapy/chemotherapy, 4 underwent vertical partial laryngectomy (3 of them with cervical lymphatic dissection), 3 underwent supported laryngoscopic plasma laryngectomy for laryngeal cancer, and 1 abandoned for treatment. With the follow-up of 8 -78 months, 5 patients were alive, 1 died from chemotherapy reactions, 3 died from other diseases, 1 died from lung metastasis, 1 died from lung infection and 1 was lost to follow-up. Conclusion: LNEC is clinically rare, the clinical manifestations are less specificity, diagnosis relies on pathological and immunohistochemical examinations, and treatment modalities and prognoses are closely related to the pathological subtypes of LNEC.

Abstract
BACKGROUND Multiple endocrine neoplasia type 2B is a rare syndrome caused mainly by Met918Thr germline RET mutation, and characterised by medullary thyroid carcinoma, phaeochromocytoma, and extra-endocrine features. Data are scarce on the natural history of multiple endocrine neoplasia type 2B. We aimed to advance understanding of the phenotype and natural history of multiple endocrine neoplasia type 2B, to increase awareness and improve detection. METHODS This study was a retrospective, multicentre, international study in patients carrying the Met918Thr RET variant with no age restrictions. The study was done with registry data from 48 centres globally. Data from patients followed-up from 1970 to 2016 were retrieved from May 1, 2016, to May 31, 2018. Our primary objectives were to determine overall survival, and medullary thyroid carcinoma-specific survival based on whether the patient had undergone early thyroidectomy before the age of 1 year. We also assessed remission of medullary thyroid carcinoma, incidence and treatment of phaeochromocytoma, and the penetrance of extra-endocrine features. FINDINGS 345 patients were included, of whom 338 (98%) had a thyroidectomy. 71 patients (21%) of the total cohort died at a median age of 25 years (range <1-59). Thyroidectomy was done before the age of 1 year in 20 patients, which led to long-term remission (ie, undetectable calcitonin level) in 15 (83%) of 18 individuals (2 patients died of causes unrelated to medullary thyroid carcinoma). Medullary thyroid carcinoma-specific survival curves did not show any significant difference between patients who had thyroidectomy before or after 1 year (comparison of survival curves by log-rank test: p=0·2; hazard ratio 0·35; 95% CI 0.07-1.74). However, there was a significant difference in remission status between patients who underwent thyroidectomy before and after the age of 1 year (p<0·0001). There was a significant difference in remission status between patients who underwent thyroidectomy before and after the age of 1 year (p<0·0001). In the other 318 patients who underwent thyroidectomy after 1 year of age, biochemical and structural remission was obtained in 47 (15%) of 318 individuals. Bilateral phaeochromocytoma was diagnosed in 156 (50%) of 313 patients by 28 years of age. Adrenal-sparing surgery was done in 31 patients: three (10%) of 31 patients had long-term recurrence, while normal adrenal function was obtained in 16 (62%) patients. All patients with available data (n=287) had at least one extra-endocrine feature, including 106 (56%) of 190 patients showing marfanoid body habitus, mucosal neuromas, and gastrointestinal signs. INTERPRETATION Thyroidectomy done at no later than 1 year of age is associated with a high probability of cure. The reality is that the majority of children with the syndrome will be diagnosed after this recommended age. Adrenal-sparing surgery is feasible in multiple endocrine neoplasia type 2B and affords a good chance for normal adrenal function. To improve the prognosis of such patients, it is imperative that every health-care provider be aware of the extra-endocrine signs and the natural history of this rare syndrome. The implications of this research include increasing awareness of the extra-endocrine symptoms and also recommendations for thyroidectomy before the age of 1 year. FUNDING None.

Abstract
Objective: To explore the clinical efficacy of unilateral vidian neurectomy following endoscopic trans-sphenoethmoidal recess approach in treating allergic rhinitis.Method: The clinical data of 80 patients with moderate-severe allergic rhinitis who underwent unilateral vidian neurectomy following endoscopic trans-sphenoethmoidal recess approach were reviewed retrospectively. Visual analogue scale(VAS) was used to assess total symptom scores and nasal symptoms including nasal itching, nasal sneezing, rhinorrhea and nasal congestion. The paired T test was used to compare the scores between surgical side and control side. Twenty-four patients with 3 years of follow-up were assessed by analysis of variance with comparison of means between multiple groups. Further comparison between any two means was performed by LSD-t test. Result: A total of 80 patients were followed up for one year, with 51 patients for two years and 24 patients for three years. Among 24 patients, total symptom scores and nasal symptoms (nasal itching, nasal sneezing, rhinorrhea and nasal congestion) at pre-operation, 1 year,2 year and 3 year after operation were compared between surgical side and control side. There was no significant difference by the paired T test(P>0.05),but there was statically significant by analysis of variance(P<0.05) .The analysis of LSD-t test showed significant differences between pre-operative time point and each of the three time points after operation (P<0.05). Conclusion:The unilateral vidian neurectomy following endoscopic trans-sphenoethmoidal recess approach is an safe and effective technique in the management of moderate severe allergic rhinitis,and unilateral surgery could relieve bilateral nasal symptoms.

Abstract
Objective: To investigate the effect of interleukin-4 (IL-4) stimulation on the expression of FcεRⅠα and NK-1R on mature mast cells(MC) cultured and differentiated from mouse bone marrow stem cells, and then to study if these MC also respond to substance P (SP) both in FcεRⅠα and NK-1R dependent manners. Methods: Bone marrow cells were aseptically flushed from BALB/c mouse femurs into complete RPMI 1640, followed by culture with stem cell factor (SCF 100 μg/L), IL-3 (15 μg/L) and IL-4 (0, 10, 15, 20 and 25 μg/L, respectively). The culture medium was changed once a week. The morphological changes of culture cells were observed under inverted microscope. After 4 weeks culture, the cells were collected and appraised by toluidine blue staining and flow cytometry. The expressions of surface CD117, FcεRⅠα and NK-1R on these cells were detected by flow cytometry and Western blot. Bone marrow MC were activated with SP (0, 0.01, 0.1, 1.0 and 10 mg/L, respectively) for 30 min. The histamine released into the supernatant and stored in the protoplasm was quantified by enzyme linked immunosorbent assay (ELISA). The percentage of histamine release was calculated as a percent of total histamine content. Results: When different concentrations of IL-4 (0, 10, 15, 20, 25 μg/L)were added into RPMI 1640, the positive rates of CD117 on MC surface were expressed as (94.8±1.3)%, (95.7±2.5)%, (94.1±1.3)%, (96.6±1.0)%, and (96.6±1.1)%, respectively, and there was no significant difference among these groups (F=8.51, P>0.05). The positive rates of FcεRⅠα were expressed as (81.5±2.6)%, (84.2±1.8)%, (91.8±2.0)%, (91.6±1.6)%, and (93.0±2.6)%, respectively, and there was statistically increasing among these groups (F=15.76, P<0.05). Then MC were activated by SP (0, 0.01, 0.1, 1.0, 10 mg/L), histamine from 20 μg/L IL-4 group were released (20.08±1.50)%, (32.76±2.99)%, (42.90±3.36)%、(50.21±1.29)%, (56.10±3.60)%, as similar as from 0 μg/L IL-4 were (19.37±2.02), (19.50±1.50), (21.77±1.91), (32.00±2.50), (33.56±1.25), there was significantly different when compared with each other (all P<0.05). Bone marrow MC were shown to have the highest expression of FcεRⅠα and NK-1R in culture of 20 μg/L IL-4 by the detection of Western blot, meanwhile these MC could be activated to degranulate by a lower concentration of SP (0.01 mg/L), with the release rate of histamine from MC showing a positive correlation with SP concentrations. On the other hand, MC with high expression of FcεRⅠα and little expression of NK-1R cultured with 0 μg/L IL-4, could also be activated by a much higher concentration of SP (1.0 mg/L). Conclusions: Bone marrow mast cells were shown to be successfully differentiated and to express NK-1R and FcεRⅠα upon co-culture with SCF and IL-3 or SCF, IL-3 and IL-4.When IL-4 was added into RPMI 1640, bone marrow MC could highly produce FcεRⅠα and NK-1R, thus building a better model of MC degranulation regulated by SP. And SP-controlled MC degranulation may be mediated through both FcεRⅠα (immunologically) and NK-1R (non-IgE mediated or non-immunologically) pathway.
