ABSTRACT Objective: To investigate the characteristics of thyroid invasion and central lymph node metastasis of hypopharyngeal carcinoma, and the impact on survival rate and quality of life. Methods: A retrospective analysis of 124 cases (122 males and 2 females with age range from 36 to 78 years old) with laryngopharyngeal squamous cell carcinoma who were initially treated in the Department of Head and Neck Surgery, Beijing Tongren Hospital Affiliated to Capital Medical University from January 2014 to December 2017 was performed. The clinical data included tumor location, pathological T stage, pathological N stage, invasion of thyroid gland, central lymph node metastasis, surgical procedures and so on. Patients were grouped according to if presence of thyroid invasion and central lymph node metastasis. Wit h follow-up, the survival was analyzed by Kaplan-Meier method, and tumor recurrence and metastasis were evaluated. Results: Of the patients, 12 patients had thyroid involvement and 5 patients had central lymph node metastasis. The incidence of thyroid involvement was 8.16% (8/98) in pyriform sinus, 1/18 in posterior pharyngeal wall and 3/8 in posterior cricoid wall, with statistically significant difference (χ2=15.076,P=0.008). The incidence of central lymph node metastasis was 1.02% (1/98) in pyriform sinus, 3/18 in posterior pharyngeal wall and 1/8 in posterior cricoid wall, also with statistically significant difference (χ2=11.205, P=0.008). There was no statistical correlation between thyroid invasion or central lymph node metastasis and gender, smoking or alcohol exposure history and tumor pathological differentiation (all P>0.05). The 3-year overall survival rate was 80.65% and the 3-year recurrence free rate was 85.48%. T otally 24 patients died in 3 years, including 4 cases in thyroid invasion group and 1 case in central lymph node metastasis group. Local recurrence occurred in 18 patients, including 4 cases in thyroid invasion group and 1 case in central lymph node metastasis group. There was no significant difference in survival between patients with and without thyroid invasion and central lymph node metastasis (all P>0.05). There were significantly difference in 3-year overall survival and relapse-free survival among the groups with different T stages, N stages, pathological stages and tumor pathological differentiation levels (all P<0.05). There were significantly differences in the levels of serum calcium and FT3 between the groups with or without thyroid invasion and central lymph node metastasis (all P<0.05). Conclusion: The incidences of thyroid invasion and central lymph node metastasis of hypopharyngeal carcinoma are rare, and the risk of occurrence is related to the primary site of tumor. Comprehensive evaluation, correct decision-making and accurate treatment could be helpful to cure radically the tumor, to prevent recurrence and to improve the quality of life of patients.

Identification and genetic analysis of new mutations in EYA1 gene of BOS syndrome

xlomafota13 shared this article with you from Inoreader Identification and genetic analysis of new mutations in <em>EYA1</em> gene of BOS syndrome Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Sep 7;56(9):966-971. doi: 10.3760/cma.j.cn115330-20210126-00040. ABSTRACT Objective: To analyze the clinical manifestations of a patient with branchiootic syndrome(BOS) and her families and to carry out genetic testing in order to specify the biological pathogenesis. Methods: Clinical data of the patient and her families were collected. Genomic DNA in the peripheral blood of the proband and her family members was extracted. All exons of 406 deafness-related susceptible genes as well as their flanking regions were sequenced by high-throughput sequencing, and the mutation sites of the proband and her parents were validated by Sanger sequencing. Results: There were nine members in three generations, of whom four presented with hearing loss, preauricular fistula and branchial fistula which met the diagnostic criteria of BOS. Proband and her mother presented with auric le malformation and inner ear malformation. And no one had abnormalities in the kidneys of all the patients. Pedigree analysis revealed that the mode of inheritance in the family was consistent with the autosomal dominant pattern. Mutational analysis showed that all the affected patients detected a heterozygous frameshift variation c.1255delT in the EYA1 gene, which had not been reported. Genotype and phenotype were co-isolated in this family. Such a frameshift variation produced a premature termination codon, thereby causing premature termination of translation (p.C419VFS*12). ACMG identified that the mutation was pathogenic. This mutation was novel and not detected in controls. A heterozygous missense variation mutation c.403G>A(p.G135S) in EYA1 gene was also detected in three members of this family. ACMG identified that the mutation clinical significance was uncertain. However, two of whom were normal, which seemed the disease was not caused by this mutation in t his family. Conclusions: A novel frameshift mutation in EYA1(c.1255delT) is the main molecular etiology of BOS in the Chinese family. This study expands the mutational spectrum of EYA1 gene. The clinical manifestations are heterogeneous among patients in this family. The diagnosis of BOS should combine gene tests with clinical phenotypes analysis.

xlomafota13 shared this article with you from Inoreader Correlation between different body mass index and anatomical position of tongue artery Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Sep 7;56(9):977-980. doi: 10.3760/cma.j.cn115330-20201112-00867. ABSTRACT Objective: To compare the anatomical position of the lingual artery in people with different body mass index (BMI), and to observe whether there is a correlation between different body mass index, height, weight with tongue length, tongue width, bilateral lingual artery distance and lingual artery depth, so as to estimate the position of the lingual artery during the operation to guide the operation. Methods: Three hundred and fourteen subjects who underwent CT angiography (computed tomography angiograph, CTA) at the First Affiliated Hospital of Chongqing Medical University from June 2020 to September 2020 were randomly selected for retrospective analysis, including 190 males and 124 females people,aged from 20 to 73 years old. The subjects were divided into 4 groups: low body weight (BMI<18.5 k g/m2, n=32), normal body weight (18.5 kg/m2≤BMI<24 kg/m2, n=164), super weight group (24 kg/m2≤BMI<28 kg/m2, n=93), and obesity group (BMI≥28 kg/m2, n=25). The subjects' tongue length and tongue width, bilateral lingual artery spacing and lingual artery depth at each measurement point were measured respectively. The differences in anatomical data between the groups were compared to see if there was statistical significance. Meanwhile, the correlation between BMI and various anatomical parameters was analyzed. Statistical analysis was performed using SPSS 22.0 software. Results: There was no significant difference in age and gender composition ratio between the four groups of subjects (P>0.05). There was no significant difference in tongue width and bilateral lingual artery distance at 3 measurement points in each group (P>0.05). There was significant d ifference in tongue length and lingual artery depth at each measurement point (P<0.001). Pearson correlation analysis showed that BMI was significantly positively correlated with bilateral lingual artery distance at each measurement point (r=0.372, 0.395, 0.232, P<0.001), and BMI was significantly positively correlated with lingual artery depth at each measurement point (r=0.312, 0.461, 0.453, P>0.001). BMI was significantly positively correlated with tongue length (r=0.441, P<0.001), but not with tongue width. Conclusions: In patients with different BMI values, the location of the lingual artery is different and positively correlated. Individual surgical plans should be made according to patients with different BMI values during tongue body surgery to avoid damage to the lingual artery.

xlomafota13 shared this article with you from Inoreader Short-term efficacy of anti-IgE monoclonal antibody in patients with recurrent chronic rhinosinusitis with nasal polyps combined with asthma Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Oct 7;56(10):1035-1041. doi: 10.3760/cma.j.cn115330-20210608-00338. ABSTRACT Objective: To investigate the short-term efficacy of anti-IgE monoclonal antibody (Omalizumab) in the treatment of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP) complicated with asthma. Methods: Patients with recurrent CRSwNP and comorbid asthma in Beijing TongRen Hospital from May to December of 2020 were continuously recruited and received a 4-month therapy of stable background treatment plus Omalizumab. Results of visual analog scales (VAS) of nasal symptoms, sino-nasal outcome test-22 (SNOT 22) and nasal polyp scores were collected at baseline and post-treatment (1, 2, 3 and 4 months after treatment). Blood routine tests, total nasal resistances (TNR), minimum cross-sectional areas (MCA), total nasal cavity volumes (NCV), forced expiratory volumes in one second (FEV1)/forced vi tal capacity (FVC) and adverse events were collected at baseline and 4 months after treatment. All results were evaluated for short-term efficacy of Omalizumab. GraphPad Prism 8.2.1 was used for statistic analysis. Results: Ten patients were collected, including 3 males and 7 females, aged (41.13±12.64) years old (x¯±s). Compared to results at baseline, the VAS scores of nasal obstruction, rhinorrhea, hyposmia and headache after 4 months treatment were significantly decreased (1.80±1.48 vs 6.70±2.83, 2.40±1.27 vs 6.40±3.44, 2.70±2.91 vs 8.20±2.25, 0.60±1.08 vs 3.60±2.72, t value was 5.045, 4.243, 5.312, 3.402, respectively, all P<0.01). The scores of SNOT-22 (25.6±20 vs 61.3±33.32, t=4.127, P=0.002 6), nasal polyp scores (2.20±0.92 vs 4.60±0.84, t=9.000, P<0.01) and the count and percentage of eosinophils in peripheral blood were significantly decreased ((94.10±97.78)×10 9/L vs (360.00±210.80)×109/L, (32.90±27.06)% vs (64.40±20.73)%, t value was 3.678, 2.957, respectively, all P<0.05). NCV (0-5 cm and 0-7 cm) of patients were improved from baseline ((12.62±2.84) cm3 vs (10.40±2.09) cm3, (27.50±14.15) cm3 vs (16.81±6.40) cm3, t value was 2.371, 2.445, respectively, all P<0.05). Conclusions: The 4-month treatment of Omalizumab can significantly improve the nasal symptoms and quality of life of patients with recurrent CRSwNP complicated with asthma, shrink nasal polyps size and reduce the number of peripheral blood eosinophils. Omalizumab can be used as an alternative therapy for refractory CRSwNP patients in the future. PMID:34666463 | DOI:10.3760/cma.j.cn115330-20210608-00338 View on the web Inoreader.

Concordant systemic and local eosinophilia relates to poorer disease control in patients with nasal polyps

xlomafota13 shared this article with you from Inoreader Concordant systemic and local eosinophilia relates to poorer disease control in patients with nasal polyps Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Oct 7;56(10):1042-1050. doi: 10.3760/cma.j.cn115330-20210428-00235. ABSTRACT Objective: To explore whether blood and polyp tissue eosinophil numbers are independent risk factors for poor disease control in patients with nasal polyp. Methods: By using the electronic medical records database and manual evaluation, 183 nasal polyp patients who had undergone endoscopic sinus surgery at least one year prior to the study with complete data of tissue specimens, baseline blood routine test, nasal endoscopy and sinus computed tomography, were identified and recruited to assess disease control based on the criteria of a European Position Paper on Rhinosinusitis and Nasal Polyps 2012 (EPOS 2012). Multiple logistic regression model was used to determine the association between blood and tissue eosinophil numbers and risk of poor disease control by adjusting for demographics and como rbidities. Results: We broke down the cohort into 4 groups according to blood (0.3×109/L) and tissue (10%) eosinophils. The patients without eosinophilic inflammation represented the largest group (41.5%). The group with concordant blood and tissue eosinophilia represented the second largest (31.2%), and the patients with isolated tissue (15.3%) or blood (12.0%) eosinophilia were relatively rare. Multiple logistic regression models found blood eosinophil count and tissue eosinophil percentage were independently associated with increased risk for poor disease control after adjustments for covariates related to poor treatment outcome. Furthermore, subjects with concordant blood and tissue eosinophilia had a higher risk for poor disease control than those with isolated blood or tissue eosinophilia. Conclusion: Concordant blood and tissue eosinophilia relates to a higher likelihood of poor disease control than isolated blood or tissue eosinophilia after adjustm ent of potential confounders in nasal polyp patients.

Predictive diagnostic value of serum 25-hydroxyvitamin D3 in eosinophilic chronic rhinosinusitis with nasal polyps

xlomafota13 shared this article with you from Inoreader Predictive diagnostic value of serum 25-hydroxyvitamin D3 in eosinophilic chronic rhinosinusitis with nasal polyps Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Oct 7;56(10):1051-1058. doi: 10.3760/cma.j.cn115330-20210427-00232. ABSTRACT Objective: To compare the value of 25-hydroxyvitamin D3 (25-(OH)D3) with other clinical parameters in the prediction and diagnosis of eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Methods: Eligible chronic rhinosinusitis with nasal polyps (CRSwNP) patients and healthy subjects in the Affiliated Hospital of Guizhou Medical University from January to April of 2021 were included for this study. The age, gender, past history and other basic characteristics of all subjects were recorded. The CRSwNP patients were classified into ECRSwNP and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP) endotypes by the percentage of tissue eosinophils. Serum 25-(OH)D3 levels measurements were performed in all subjects. Paranasal sinus CT scans, blood eosinophil counts, and det ermination of total immunoglobulin E (total IgE), Th1/Th2 plasma cytokines and nasal nitric oxide (nNO) levels were performed before surgery. Logistic regression analysis was used to evaluate the related factors of ECRSwNP. Receiver operating characteristic (ROC) curves was used to evaluate the predictive potential of the clinical parameters. Results: One hundred and twenty-seven CRSwNP patients and 40 healthy subjects were recruited, including 74 males and 93 females of the patients, with the age of (38.73±13.05) years. In patients with ECRSwNP, serum 25-(OH)D3 levels were significantly lower than those in nECRSwNP patients ((26.14±4.58) ng/ml vs (35.71±7.86) ng/ml, t=-8.564, P<0.01). The prevalence of asthma, prevalence of allergic rhinitis, peripheral blood eosinophil counts, total IgE levels, nNO levels and CT scores ratio for ethmoid sinus and maxillary sinus (E/M ratio) of ECRSwNP patients were significantly higher than those in nECRSwNP patie nts (all P<0.05). However, there was no significant difference in Th1/Th2 cytokines levels between the histological types of CRSwNP (all P>0.05). Among the predictive indicators, 25-(OH)D3 had the highest predictive value, with ROC area under curve (AUC) value of 0.882. The best cut-off point of 28.5 ng/ml for 25-(OH)D3 demonstrated a sensitivity of 0.871 and a specificity of 0.762 for ECRSwNP. Conclusion: Measurement of serum 25-(OH)D3 level may be used as an effective method to distinguish between ECRSwNP and nECRSwNP.

The expression and significance of TRPM8 among chronic rhinosinusitis with nasal polyps

xlomafota13 shared this article with you from Inoreader The expression and significance of TRPM8 among chronic rhinosinusitis with nasal polyps Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Oct 7;56(10):1059-1065. doi: 10.3760/cma.j.cn115330-20210430-00243. ABSTRACT Objective: To compare the expression and difference of melastatin-related transient receptor potential 8(TRPM8) among chronic rhinosinusitis, nasal polyps and normal mucosa tissues. And to explore the significant expression of TRPM8 among CRSwNP. Methods: Fifty-one patients underwent endoscopic sinus surgery in the Department of Otorhinolaryngology Head and Neck Surgery of Renmin Hospital of Wuhan University from February 2019 to January 2020 were recruited, including 33 males and 18 females, aged from 14 to 65 years old (34.55±1.689).Immunohistochemistry was used to detected the expression of TRPM8 protein among CRSsNP(17),CRSwNP (17) and control tissuses(17). In addition, the correlation between the expression of TRPM8 protein in CRSwNP patients and preoperative CT Lund-Mackay scores and preo perative VAS scores and sinonasal outcome test-20 scores was analyzed, respectively. The primary human nasal epithelial cells were cultured in vitro and the expression of TRPM8 was detected by quantitative real-time PCR and western blotting. The tissue in control group, chronic rhinosinusitis without nasal polyps (CRSsNP) group and the CRSwNP group were collected and grinded into tissue homogenized. The expression of TRPM8 protein was detected by western blotting after 24 h stimulation after homogenate was added into the medium of RPMI 2650 and primary nasal epithelial cells. Results: Compared with the control, the expression of TRPM8 was significantly up-regulated in nasal polyps (t=6.852, P<0.05). TRPM8 was mainly expressed in epithelial cells. The expression of TRPM8 in the epithelial cells of CRSsNP had no difference with the control group (t=1.980, P>0.05). In addition, the expression of TRPM8 in CRSwNP patients was positively cor related with the preoperative CT Lund-Mackay scores and VAS scores and SNOT-20 scores (r=0.512, P<0.05;r=0.853, P<0.01;r=0.814, P<0.01). After cultured primary epithelial cells in vitro, the expression level of TRPM8 in epithelial cells derived from nasal polyp was significantly higher than that in control group (t=8.845, P<0.05). By adding the homogenization of control and CRSsNP and CRSwNP tissues, the expression of TRPM8 in RPMI 2650 cells and primary nasal epithelial cells was changed and that was significantly increased after adding the homogenization of the group of CRSwNP. Conclusion: TRPM8 is highly expressed in nasal polyps epithelial cells, suggesting that TRPM8 may be involved in the pathogenesis of nasal polyps regulated by nasal epithelial cells.

xlomafota13 shared this article with you from Inoreader Gene transcriptome analysis of nasal epithelial cells in chronic rhinosinusitis with nasal polyps Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Oct 7;56(10):1066-1072. doi: 10.3760/cma.j.cn115330-20210422-00219. ABSTRACT 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 con firmed 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 c omplex. 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.
