Abstract
Van der Hoeve's syndrome, also known as osteogenesis imperfecta (OI), is a genetic connective tissue disorder characterized by fragile, fracture-prone bone and hearing loss. The disease is caused by a gene mutation in one of the two type I collagen genes COL1A1 or COL1A2. In this study, we identified a novel frameshift mutation of the COL1A1 gene (c.1607delG) in a family with OI using whole-exome sequencing, bioinformatics analysis and Sanger sequencing. This mutation may lead to the deletion of a portion of exon 23 and the generation of a premature stop codon in the COL1A1 gene. To further investigate the impact of this mutation, we established two induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells of OI patients carrying a novel mutation in the COL1A1 gene. Osteoblasts (OB) derived from OI-iPSCs exhibited reduced production of type I collagen and diminished ability to differentiate into osteoblasts. Using a CRISPR-based homology-directed repair strategy, we corrected the OI disease-causing COL1A1 novel mutations in iPSCs generated from an affected individual. Our results demonstrated that the diminished expression of type I collagen and osteogenic potential were enhanced in OB induced from corrected OI-iPSCs compared to those from OI-iPSCs. Overall, our results provide new insights into the genetic basis of Van der Hoeve's syndrome and highlight the potential of iPSC technology for disease modeling and therapeutic development.

Abstract
Waardenburg syndrome type 1 (WS1) is a hereditary disease mainly characterized by sensorineural hearing loss, dystopia canthorum, and pigmentary defects. To elucidate molecular mechanisms underlying PAX3-associated hearing loss, we developed inner ear organoids model using induced pluripotent stem cells (iPSCs) derived from WS1 patient and healthy individual. Our results revealed a significant reduction in the size of inner ear organoids, accompanied by an increased level of apoptosis in organoids derived from WS1 patient-iPSCs carrying PAX3 c.214A > G. Transcriptome profiling analysis by RNA-seq indicated that inner ear organoids from WS1 patients were associated with suppression of inner ear development and WNT signaling pathway. Furthermore, the upregulation of the WNT1/β-catenin pathway which was achieved through the correction of PAX3 isogenic mutant iPSCs using CRISPR/Cas9, contributed to an increased size of inner ear organoids and a reduction in apoptosis. Together, our results provide insight into the underlying mechanisms of hearing loss in WS.

Abstract
Objective: To analyze the treatment outcomes and prognoses of children with head and neck non-parameningeal rhabdomyosarcoma (HNnPM RMS). Methods: A retrospective analysis was performed on the clinical data of children with HNnPM RMS admitted to Beijing Children's Hospital from September 2012 to September 2022. The clinical features, comprehensive treatment modes and prognoses of the patients were analyzed. The overall survival rate (OS) and event free survival rate (EFS) were calculated using the Kaplan-Meier method, and univariate analysis was performed using the Log-rank test. Results: A total of 70 children were included in this study, 38 males and 32 females, with a median age of 47 months (2-210 months). Pathological subtypes including the embryonal in 27 cases, the alveolar in 36 cases and the spindle cell and sclerosing in 7 cases. Thirty children (83.3%) with alveolar type were positive for FOXO1 gene fusion. All 70 children underwent chemotherapy, including 38 with neoadjuvant chemotherapy and 32 with adjuvant chemotherapy. Sixty of 70 children underwent surgery, of whom, 10 underwent two or more surgeries. There were 63 children underwent radiotherapy, including 54 with intensity-modulated radiation therapy, 4 with particle implantation and 5 with proton therapy. The median follow-up was 45 (5-113) months, the 5-year OS was 73.2%, and the 5-year EFS was 57.7%. Univariate analysis showed lymph node metastasis (χ2=5.022, P=0.025), distant metastasis (χ2=8.258, P=0.004), and high Intergroup Rhabdomyosarcoma Study (IRS) group (χ2=9.859, P=0.029) as risk factors for poor prognosis. Before June 2016, the 5-year OS based on BCH-RMS-2006 scheme was 63.6%, and after 2016, the 5-year OS based on CCCG-RMS-2016 scheme was 79.6%. Conclusion: Multidisciplinary combined standardized treatment can offer good treatment outcome and prognosis for children with HNnPM RMS. Local control is a key to the efficacy of comprehensive treatment.

Abstract
Waardenburg Syndrome (WS) is a rare genetic disorder that leads to congenital hearing loss and pigmentation defects. Microphthalmia-associated transcription factor (MITF) is one of its significant pathogenic genes. Despite the comprehensive investigation in animal models, the pathogenic mechanism is still poorly described in humans due to difficulties accessing embryonic tissues. In this work, we used induced pluripotent stem cells derived from a WS patient carrying a heterozygous mutation in the MITF gene c.626A>T (p.His209Leu), and differentiated toward melanocyte lineage, which is the most affected cell type involved in WS. Compared with the wild-type cell line, the MITFmut cell line showed a reduced expression of the characteristic melanocyte-related genes and a lesser proportion of mature, fully pigmented melanosomes. The transcriptome analysis also revealed widespread gene expression changes at the melanocyte stage in the MITFmut cell line. The differentially expressed genes were enriched in melanogenesis and cell proliferation-related pathways. Interestingly, ion transport-related genes also showed a significant difference in MITFmut -induced melanocytes, indicating that the MITF mutant may lead to the dysfunction of potassium channels and transporters produced by intermediate cells in the cochlea, further causing the associated phenotype of deafness. Altogether, our study provides valuable insights into how MITF mutation affects WS patients, which might result in defective melanocyte development and the related phenotype based on the patient-derived iPSC model.

Abstract
Tympanosclerosis is the hyaline degeneration and calcium deposition of the lamina propria of tympanic membrane and the submucosa of middle ear under long-term chronic inflammatory stimulation. At present, treatment primarily involves the surgical removal of sclerotic foci and reconstruction of auditory ossicular chain. However, excision of sclerotic lesions near critical structures like the facial nerve canal and vestibular window may result in complications like facial paralysis, vertigo, and sensorineural hearing loss. Developing safer and more effective treatments for tympanosclerosis has become an international research focus. Recent years have seen novel explorations in the treatment of tympanosclerosis. Therefore, this article reviews the latest advancements in research on the treatment of tympanosclerosis.

Abstract
Aminoglycoside antibiotics are among the most common agents that can cause sensorineural hearing loss. From clinical experience, premature babies, whose inner ear is still developing, are more susceptible to aminoglycoside-induced ototoxicity, which is echoed by our previous study carried out in organotypic cultures. This study aimed to investigate whether a nonselective cation channel, TRPV1, contributes to the susceptibility of immature spiral ganglion neurons (SGNs) to the damage caused by aminoglycosides. Through western blotting and immunofluorescence, we found that the TRPV1 expression levels were much higher in immature SGNs than in their mature counterparts. In postnatal day 7 cochlear organotypic cultures, AMG-517 reduced reactive oxygen species generation and inhibited SGN apoptosis under aminoglycoside challenge. However, in adult mice, AMG-517 did not ameliorate the ABR threshold increase at high frequencies (16 kHz and 32 kHz) after aminoglycoside administration, and the SGNs within the cochleae had no morphological changes. By further regulating the function of TRPV1 in primary cultured SGNs with its inhibitor AMG-517 and agonist capsaicin, we demonstrated that TRPV1 is a major channel for aminoglycoside uptake: AMG-517 can significantly reduce, while capsaicin can significantly increase, the uptake of GTTR. In addition, TRPV1 knockdown in SGNs can also significantly reduce the uptake of GTTR. Taken together, our results demonstrated that aminoglycosides can directly enter immature SGNs through the TRPV1 channel. High expression of TRPV1 contributes to the susceptibility of immature SGNs to aminoglycoside-induced damage. The TRPV1 inhibitor AMG-517 has the potential to be a therapeutic agent for preventing aminoglycoside-induced ototoxicity in immature SGNs.

A Novel EYA1 Mutation Causing Alternative RNA Splicing in a Chinese Family With Branchio-Oto Syndrome: Implications for Molecular Diagnosis and Clinical Application. Clin Exp Otorhinolaryngol 2023; 16:342-358.

Abstract
OBJECTIVES Branchio-oto syndrome (BOS) primarily manifests as hearing loss, preauricular pits, and branchial defects. EYA1 is the most common pathogenic gene, and splicing mutations account for a substantial proportion of cases. However, few studies have addressed the structural changes in the protein caused by splicing mutations and potential pathogenic factors, and several studies have shown that middle-ear surgery has limited effectiveness in improving hearing in these patients. BOS has also been relatively infrequently reported in the Chinese population. This study explored the genetic etiology in the family of a proband with BOS and provided clinical treatment to improve the patient's hearing. METHODS We collected detailed clinical features and peripheral blood samples from the patients and unaffected individuals within the family. Pathogenic mutations were identified by whole-exome sequencing and cosegregation analysis and classified according to the American College of Medical Genetics and Genomics guidelines. Alternative splicing was verified through a minigene assay. The predicted three-dimensional protein structure and biochemical experiments were used to investigate the pathogenicity of the mutation. The proband underwent middle-ear surgery and was followed up at 1 month and 6 months postoperatively to monitor auditory improvement. RESULTS A novel heterozygous EYA1 splicing variant (c.1050+4 A>C) was identified and classified as pathogenic (PVS1(RNA), PM2, PP1). Skipping of exon 11 of the EYA1 pre-mRNA was confirmed using a minigene assay. This mutation may impair EYA1-SIX1 interactions, as shown by an immunoprecipitation assay. The EYA1-Mut protein exhibited cellular mislocalization and decreased protein expression in cytological experiments. Middle-ear surgery significantly improved hearing loss caused by bone-conduction abnormalities in the proband. CONCLUSION We reported a novel splicing variant of EYA1 in a Chinese family with BOS and revealed the potential molecular pathogenic mechanism. The significant hearing improvement observed in the proband after middle-ear surgery provides a reference for auditory rehabilitation in similar patients.

Abstract
The ELMOD3 gene is implicated in causing autosomal recessive/dominant non-syndromic hearing loss in humans. However, the etiology has yet to be completely elucidated. In this study, we generated a patient-derived iPSC line carrying ELMOD3 c.512A>G mutation. In addition, the patient-derived iPSC line was corrected by CRISPR/Cas9 genome editing system. Then we applied RNA sequencing profiling to compare the patient-derived iPSC line with different controls, respectively (the healthy sibling-derived iPSCs and the CRISPR/Cas9 corrected iPSCs). Functional enrichment and PPI network analysis revealed that differentially expressed genes (DEGs) were enriched in the gene ontology, such as sensory epithelial development, intermediate filament cytoskeleton organization, and the regulation of ion transmembrane transport. Our current work provided a new tool for studying how disruption of ELMOD3 mechanistically drives hearing loss.

Abstract
OBJECTIVES To summarize the clinical characteristics of glomus tympanicum tumors, and to explore the surgical methods and the strategy for auditory protection. METHODS Ten cases (ears) of glomus tympanicum tumors were collected from the Department of Otolaryngology Head and Neck Surgery, Xiangya Hospital, Central South University from August 2014 to February 2022. All patients underwent endoscopic or microscopic surgery to achieve total removal of the tumor, followed up for 3 months to 8 years. We summarized and analyzed its clinical characteristics, compared the preoperative and postoperative hearing levels of patients, and made a retrospective summary of the surgical methods and the strategy for auditory protection. RESULTS Ten patients were all female at (49.50±8.00) years old. Their medical history ranged from 15 days to 6 years. Seven patients complained of pulsatile tinnitus, and 80% (8/10) of the affected ears suffered different degrees of hearing loss. According to the modified Fisch & Mattox classification of glomus tympanicum tumors, 3 ears (30%) of 10 ears were A1, 2 ears (20%) were A2 and 5 ears (50%) were B1. In all 10 cases (ears), hearing was improved in 3 cases, bone gas conductance was maintained in 6 cases, and hearing was slightly decreased in 1 case. The difference of bone gas conductance was 0-10 dB in 7 cases (ears) after operation, and 10-20 dB in 3 cases (ears). There was no significant difference in the average air conduction hearing threshold, bone conduction hearing threshold and air-bone conduction difference between before and after operation (all P>0.05). All cases had no postoperative complications, and the external auditory canal and the incision behind the ear healed well. There was no recurrence after follow-up. CONCLUSIONS Glomus tympanicum tumor is easy to bleed, so it is a challenge for total tumor resection and hearing function protection during operation. For type A and type B1 tumors, they can be completely removed under the condition of keeping the tympanic membrane and the ossicular chain. At the same time, the postoperative hearing function can be preserved, and even the hearing can be improved.

Abstract
With the optimization of deep learning algorithms and the accumulation of medical big data, deep learning technology has been widely applied in research in various fields of otology in recent years. At present, research on deep learning in otology is combined with a variety of data such as endoscopy, temporal bone images, audiograms, and intraoperative images, which involves diagnosis of otologic diseases (including auricular malformations, external auditory canal diseases, middle ear diseases, and inner ear diseases), treatment (guiding medication and surgical planning), and prognosis prediction (involving hearing regression and speech learning). According to the type of data and the purpose of the study (disease diagnosis, treatment and prognosis), the different neural network models can be used to take advantage of their algorithms, and the deep learning can be a good aid in treating otologic diseases. The deep learning has a good applicable prospect in the clinical diagnosis and treatment of otologic diseases, which can play a certain role in promoting the development of deep learning combined with intelligent medicine.

Abstract
Objective:To summarize the clinical characteristics of elderly patients with chronic suppurative otitis media who underwent type Ⅰ tympanoplasty, and to analyze for the first time the efficacy of type Ⅰtympanoplasty in elderly patients from multiple perspectives of medical data and patient evaluation, so as to provide reference for doctors and patients to make rational decisions on treatment methods. Methods:Forty-four elderly patients(45 ears) who underwent type Ⅰtympanoplasty from May 2016 to February 2022 were retrospectively analyzed, and were followed up for 6 months to 3 years. To analyze the clinical characteristics of patients, summarize the success rate of graft, and compare the hearing level of patients before and after surgery. The patients' quality of life before and after operation was evaluated by Chronic Ear Survey, and the scores obtained were statistically analyzed. Results:Of the 44 patients(45 ears), 22.22%(10/45) of the ears had predisposing factors. The percentage of hearing loss, ear pus and tinnitus were 91.11%(41/45), 88.89%(40/45) and 42.22%(19/45), respectively. Mixed deafness accounted for 55.56%(25/45). 66.67%(30/45) patients were diagnosed as tympanosclerosis by operation. The graft success rate was 97.78%. There was no significant difference in bone conduction hearing threshold before and after surgery, but there was significant difference in air conduction hearing threshold and air bone conduction difference. The scores of "activity restriction", "symptom", "medical resource utilization" and their total scores of the preoperative and postoperative were statistically different. Hypertension or diabetes had no significant effect on the efficacy of type Ⅰ tympanoplasty in elderly patients. Conclusion:Type Ⅰtympanoplasty is safe and effective in elderly patients, and the quality of life of patients after surgery is significantly improved. It is necessary to increase the awareness of elderly patients to seek medical advice and use surgical methods reasonably to treat chronic suppurative otitis media.

Background Sudden sensorineural hearing loss (SSNHL) can cause great panic in patients. Whether it is advantageous to add intravenous batroxobin in the treatment of SSNHL remains to be determined. This study aimed to compare the short-term efficacy of therapy combined with intravenous batroxobin and that without intravenous batroxobin in SSNHL patients. Methods This retrospective study harvested the data of SSNHL patients hospitalized in our department from January 2008 to April 2021. The hearing levels on the admitted day (before treatment) and the discharge day were considered pre-treatment hearing and post-treatment hearing, respectively. The hearing gain was the difference value of pre-treatment hearing and post-treatment hearing. We used Siegel's criteria and the Chinese Medical Association of Otolaryngology (CMAO) criteria to evaluate hearing recovery. The complete recovery rate, overall effective rate, and hearing gain at each frequency were considered outcomes. Propensity score matching (PSM) was conducted to balance the baseline characteristics between the batroxobin group and the non-batroxobin group. Sensitivity analysis was carried out in flat-type and total-deafness SSNHL patients. Results During the study period, 657 patients with SSNHL were admitted to our department. Among them, a total of 274 patients met the enrolled criteria of our study. After PSM, 162 patients (81 in each group) were included in the analysis. Once the hospitalized treatment was completed, the patients would be discharged the next day. Logistic regression analysis of the propensity score-matched cohort indicated that both the complete recovery rates [Siegel's criteria, OR: 0.734, 95% CI: 0.368-1.466, p = 0.381; CMAO criteria, OR: 0.879, 95% CI: 0.435-1.777, p = 0.720] and the overall effective rates [Siegel's criteria and CMAO criteria, OR: 0.741, 95% CI: 0.399-1.378, p = 0.344] were not significantly different between the two treatment groups. Sensitivity analysis has shown similar results. For flat-type and total-deafness SSNHL patients, no significant difference was found in post-treatment hearing gain at each frequency between the two groups after PSM. Conclusion There was no significant difference in short-term hearing outcomes between treatment with batroxobin and treatment without batroxobin in SSNHL patients by Siegel's and CMAO criteria after PSM. Future studies for better therapy regimens of SSNHL are still needed.

Abstract
Background Waardenburg syndrome (WS) is the most common form of syndromic deafness with phenotypic and genetic heterogeneity in the Chinese population. This study aimed to clarify the clinical characteristics and the genetic cause in eight Chinese WS families (including three familial and five sporadic cases). Further genotype–phenotype relationships were also investigated. Methods All probands underwent screening for the known WS-related genes including PAX3, SOX10, MITF, EDNRB, EDN3, and SNAI2 using next-generation sequencing to identify disease-causing genes. Further validation using Sanger sequencing was performed. Relevant findings for the associated genotype–phenotype from previous literature were retrospectively analyzed. Result Disease-causing variants were detected in all eight probands by molecular genetic analysis of the WS genes (SOX10(NM_006941.4): c.544_557del, c.553 C > T, c.762delA, c.336G > A; MITF(NM_000248.3): c.626 A > T; PAX3(NM_181459.4): c.838delG, c.452-2 A > G, c.214 A > G). Six mutations (SOX10:c.553 C > T, c.544_557del, c.762delA; PAX3: c.838delG, c.214 A > G; MITF:c.626 A > T) were first reported. Clinical evaluation revealed prominent phenotypic variability in these WS patients. Twelve WS1 cases and five WS2 cases were diagnosed in total. Two probands with SOX10 mutations developed progressive changes in iris color with age, returning from pale blue at birth to normal tan. Additionally, one proband had a renal malformation (horseshoe kidneys).All cases were first described as WS cases. Congenital inner ear malformations were more common, and semicircular malformations were exclusively observed in probands with SOX10 mutations. Unilateral hearing loss occurred more often in cases with PAX3 mutations. Conclusion Our findings helped illuminate the phenotypic and genotypic spectrum of WS in Chinese populations and could contribute to better genetic counseling of WS.

Abstract
The human induced pluripotent stem cell (iPSC) lines, CSUXHEi001-A and CSUXHEi002-A, were generated from peripheral blood mononuclear cells (PBMCs). The donors were couple and each of them has a heterozygous mutation in the SLC26A4 gene. It manifests in their children as Enlarged vestibular aqueduct (EVA). The use of iPSC will allow describing the early stages of hearing loss, which is undoubtedly relevant for identifying key stages of development at which phenotypic manifestations of mutations in the SLC26A4 gene are found.

Abstract
PURPOSE This study aimed to determine the risk factors associated with early postoperative complications of trans-canal endoscopic ear surgery (TEES), then to develop a risk index. MATERIALS AND METHODS This single-institution retrospective study reviewed TEESs from January 1, 2017, to December 31, 2019 in a tertiary hospital. In the derivation cohort, univariable and multivariable logistic regression were performed to identify factors significantly associated with early postoperative complications of TEES. Then these parameters were integrated into a trans-canal endoscopic ear surgery risk index (TEESRI). The performance of TEESRI was compared with that of the American Society of Anesthesiologists (ASA) classification using the validation cohort. RESULTS 932 TEESs were enrolled in total and 151 (16.2%) developed early postoperative complications. In the derivation set, 8 factors including state of the opposite ear and presence of nasal or pharyngeal diseases were found to be independently associated with the occurrence of early postoperative complications on multivariable regression analysis [area under the curve (AUC), 0.806; 95% confidence interval (CI), 0.765-0.848]. Using the validation cohort, the AUC of the TEESRI was 0.776 [95%CI, 0.711-0.842], with a sensitivity of 82.2% and specificity of 65.5%, while the AUC of the ASA classification was 0.512 (95%CI, 0.421-0.603). The TEESRI outperformed the ASA classification when evaluating the risk for early postoperative complications of TEES. CONCLUSIONS Based on the 8 risk factors, the TEESRI was established with satisfactory predicting capacity. Surgeons should pay extra attention to the risk factors in the TEESRI, when treating patients.

Abstract
BACKGROUND This study aimed to investigate the perceptions and opinions of orthodontists and periodontists on the management of gingival recession in orthodontic patients. METHODS An online survey was sent to 29 periodontists and 80 orthodontists registered and currently practising in New Zealand. All participants answered questions about the timing and clinical indications of mucogingival surgeries in orthodontic patients diagnosed with mucogingival deformities. RESULTS Most periodontists and orthodontists believed that gingival grafts should ideally be performed after orthodontic treatment. In clinical practice, 40% of periodontists indicated that they would receive referrals after completion of orthodontic treatment. However, 29.6% of orthodontists indicated that they would refer to a periodontist before orthodontic treatment in clinical practice. The most crucial factor that affected periodontists' decision-making was 'evidence-based guidelines' (35.0%), followed by 'clinical experience' (30.0%) and 'patient concerns' (15.0%). All four factors of 'gingival phenotype', 'presence of gingival recession', 'amount of keratinised tissue' and 'planning specific tooth movements' were equally considered by orthodontists regarding their decision-making. CONCLUSIONS The majority of the surveyed New Zealand periodontists and orthodontists expressed a belief that the ideal timing for the management of gingival recessions would be after the completion of orthodontic treatment.

Abstract
ABCC1 gene is expressed in various tissues and organs of the human body, and can transport substrates including drugs, heavy metals, toxic substances and organic anions. Previous research on ABCC1 gene has mostly focused on tumor multidrug resistance. Recently, ABCC1 has been proposed as a candidate gene for hereditary hearing impairment, which has attracted much attention. ABCC1-associated deafness may be related to its role in biological barriers. This article has summarized recent progress in the study of the role of ABCC1 in the blood-testis barrier, placental barrier, blood-brain barrier, blood-labyrinth barrier, which may provide insight into its biological functions.

Abstract
Waardenburg syndrome (WS) is an autosomal dominant inherited disorder that is characterized by sensorineural hearing loss and abnormal pigmentation. SOX10 is one of its main pathogenicity genes. The generation of patient-specific induced pluripotent stem cells (iPSCs) is an efficient means to investigate the mechanisms of inherited human disease. In our work, we set up an iPSC line derived from a WS patient with SOX10 mutation and differentiated into neural crest cells (NCCs), a key cell type involved in inner ear development. Compared with control-derived iPSCs, the SOX10 mutant iPSCs showed significantly decreased efficiency of development and differentiation potential at the stage of NCCs. After that, we carried out high-throughput RNA-seq and evaluated the transcriptional misregulation at every stage. Transcriptome analysis of differentiated NCCs showed widespread gene expression alterations, and the differentially expressed genes (DEGs) were enriched in gene ontology terms of neuron migration, skeletal system development, and multicellular organism development, indicating that SOX10 has a pivotal part in the differentiation of NCCs. It's worth noting that, a significant enrichment among the nominal DEGs for genes implicated in inner ear development was found, as well as several genes connected to the inner ear morphogenesis. Based on the protein-protein interaction network, we chose four candidate genes that could be regulated by SOX10 in inner ear development, namely, BMP2, LGR5, GBX2, and GATA3. In conclusion, SOX10 deficiency in this WS subject had a significant impact on the gene expression patterns throughout NCC development in the iPSC model. The DEGs most significantly enriched in inner ear development and morphogenesis may assist in identifying the underlying basis for the inner ear malformation in subjects with WS.

Abstract
Emetic Bacillus cereus strains produce a potent cereulide cytotoxin, which can cause acute and fatal cases of food poisoning. We isolated 18 emetic B. cereus strains from a food poisoning event, and from clinical and non-random food surveillance in China and phenotypic characteristics of haemolysis, starch hydrolysis, salicin fermentation, gelatin liquefaction, cytotoxicity, and susceptibility to antibiotics were assessed. All isolates were positive for haemolysis and gelatin liquefaction, and negative for starch hydrolysis and salicin fermentation. Their haemolytic potentials were intermediate to Bacillus anthracis and B. cereus ATCC 14579 (a non-emetic strain). All isolates were cytotoxic to CHO, Hep-2, and Vero cells, and were sensitive to ampicillin. The homogeneous phenotypes of emetic isolates from China are similar to the corresponding traits of European and Japanese isolates that have been characterized, suggesting highly similar phenotypes of emetic B. cereus worldwide.

Abstract
Branchiootorenal spectrum disorder (BORSD) is a group of rare autosomal dominant entities characterized by branchiogenic malformations, hearing loss (HL) and renal anomalies. It comprises branchiootorenal syndrome and branchiootic syndrome, distinguished by the presence or absence of renal abnormalities. Pathogenic variants have been discovered in the following genes: EYA1, SIX5, SIX1 and SALL1. As the otological phenotype in BORSD is inconsistently reported, we performed a systematic review to provide an up-to-date overview, correlated with the genotype. Forty publications were included, describing 295 individual patients. HL was diagnosed in 95%, usually bilateral and mixed-type, and differed among the different genes involved. Mixed moderate-to-severe HL was the predominant finding in patients with EYA1 involvement, regardless of the presence of renal abnormalities. The sensorineural HL of profound severity was more prevalent in patients with SIX1 mutations. No significant differences among different mutation types or location within the genes could be observed. Structural otological manifestations, ranging from periauricular to inner ear anomalies, were common in both genes. Especially periauricular anomalies were more common and more severe in EYA1. In summary, otological differences among the different genes involved in BORSD are observed, so the molecular analysis is strongly advised.

Abstract
Waardenburg Syndrome (WS) is a common autosomal dominant syndrome associated with hearing loss. Its clinical manifestations include hearing impairment and pigmentation anomalies. In this study, we generated an induced pluripotent stem cell (iPSC) line from the Epstein-Barr virus-immortalized B lymphocytes of a 6-year-old boy affected with WS type I, caused by a heterozygous splice site mutation in the PAIRED BOX GENE 3 (PAX3) (NM_181457.3: c.452-2A > G). The patient-specific iPSC line (CSUXHi004-A) carrying the same PAX3 mutation showed a normal karyotype, expressed pluripotent markers, and presented differentiation capacity in vitro. This method may be a useful tool for the in vitro modeling of WS.

Abstract
Waardenburg syndrome (WS) is a genetic disorder characterized by sensorineural deafness. It has a variable presentation of pigmentation defects. Here, we generated an induced pluripotent stem cell (iPSC) line using episomal plasmid vectors from the fibroblasts of a 4-year-old boy affected with WS type II, caused by a novel mutation in microphthalmia-associated transcription factor (MITF) (NM_000248.3: exon6:c.626A>T). The patient-specific iPSC line (CSUXHi003-A) carrying the same MITF mutation showed normal karyotype, expressed pluripotent markers, and presented differentiation capacity in vitro. It may be a useful tool for in vitro modeling of WS.

Abstract
PURPOSE Waardenburg syndrome type 1 (WS1) is a rare genetic disorder characterized by dystopia canthorum, abnormal iris pigmentation, and congenital hearing loss with variable penetrance.WS1 is caused by mutations in paired box gene 3 (PAX3). The current study aimed to investigate the genetic cause of hearing loss in a four-generation Chinese WS1 family. METHODS The phenotype of the study family was characterized using clinical evaluation and pedigree analysis. Target region high-throughput sequencing system was designed to screen the all coding exons and flanking intronic sequences of the six WS-associated genes. Sanger sequencing was used to identify the causative nucleotide changes and perform the co-segregating analysis. The expression, subcellular distribution, and transcriptional activity of the mutant PAX3 protein were analysis to reveal the functional consequences of the mutation. RESULTS Based on diagnostic criteria, the proband of this pedigree classified as WS1. We identified a novel missense mutation (c.117 C > A, p. Asn39Lys) in exon 2 of the PAX3 gene. In vitro, the Asn39Lys PAX3 retained nuclear distribution ability. However, it failed to activate the melanocyte inducing transcription factor (MITF) promoter and impaired the function of WT PAX3. CONCLUSIONS Our study reports a novel missense PAX3 mutation in a Chinese family and shows haploinsufficiency may be the underlying mechanism for the WS1 phenotype.

Abstract
OBJECTIVES The identification of gene mutations enables more appropriate genetic counseling and proper medical management for EVA patients. The purpose of this study was to validate the accuracy and sensitivity of our method for comprehensive mutation detection in EVA, and summarize these data to explore a more accurate and convenient genetic diagnosis method. METHODS A multiplex PCR sequencing panel was designed to capture the exons of three known EVA-associated genes (SLC26A4, KCNJ10, and FOXI1), and NGS was conducted in 17 Chinese families with EVA. RESULTS A total of 16 SLC26A4 variants were found in 21 probands with bilateral EVA, including three novel variants (c.416G>A, c.823G>A and c.1027G>C), which were not reported in the dbSNP, gnomAD database, and ClinVar databases. One patient carried a FOXI1 variant (heterozygous, c.214C>A) and one patient carried a KCNJ10 variant (heterozygous, c.1054C>A), both of which were novel variants. Biallelic potential pathogenic variants were detected in 21/21patient samples, leading to a purported diagnostic rate of 100%. All results were verified by Sanger sequencing. CONCLUSION This result supplemented the mutation spectrum of EVA, and supports that combined multiple PCR-targeted enrichment, and NGS is a valuable molecular diagnostic tool for EVA, and is suitable for clinical application.

Abstract
Objective:To detect 20 common deafness gene mutations in non- syndromic deafness patients in China using PCR- RDB, and analyze and summarize the mutation data to explore the clinical value of this method. Method:The PCR- RDB and Sanger sequencing were used to detect 20 common mutations of four deafness genes(GJB2, GJB3, SLC26A4 and mtDNA) in 500 patients with non- syndromic hearing loss . The Sanger sequencing was used to compare the sensitivity, specificity, positive predictive value, negative predictive value, and total coincidence rate of the deafness mutation detected by PCR- RDB. Result:A total of 500 samples were detected. 147 wild- type samples, 81 homozygous mutant samples, 240 heterozygous mutant samples, 32 composite heterozygous mutant samples were detected using the PCR- RDB within the range of 20 gene mutations, which were identical to the Sanger sequencing results. GJB2 c.235delC and SLC26A4 c.919- 2 A>G are the most common hotspot mutations in this study, followed by mtDNA m. 1555 A>G. Compared with the Sanger sequencing method, the sensitivity, specificity, positive predictive value, negative predictive value, and total coincidence rate of the real- time fluorescence PCR melting curve method were 100%, and the Kappa value was one. Conclusion:PCR reverse dot-blot hybridization is a simple, rapid, sensitive and specific method for detecting 20 mutations of 4 common deafness genes in Chinese population, it is expected to be used in clinical detection of deafness genes in the future.

Abstract
ELMOD3, an ARL2 GTPase-activating protein, is implicated in causing hearing impairment in humans. However, the specific role of ELMOD3 in auditory function is still far from being elucidated. In the present study, we used the CRISPR/Cas9 technology to establish an Elmod3 knockout mice line in the C57BL/6 background (hereinafter referred to as Elmod3-/- mice) and investigated the role of Elmod3 in the cochlea and auditory function. Elmod3-/- mice started to exhibit hearing loss from 2 months of age, and the deafness progressed with aging, while the vestibular function of Elmod3-/- mice was normal. We also observed that Elmod3-/- mice showed thinning and receding hair cells in the organ of Corti and much lower expression of F-actin cytoskeleton in the cochlea compared with wild-type mice. The deafness associated with the mutation may be caused by cochlear hair cells dysfunction, which manifests with shortening and fusion of inner hair cells stereocilia and progressive degeneration of outer hair cells stereocilia. Our finding associates Elmod3 deficiencies with stereocilia dysmorphologies and reveals that they might play roles in the actin cytoskeleton dynamics in cochlear hair cells, and thus relate to hearing impairment.

Abstract
OBJECTIVES Recent reports have identified autoimmune systemic diseases as a significant risk factor for sudden sensorineural hearing loss (SSNHL). We investigated whether systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) were correlated with the hearing recovery of SSNHL. STUDY DESIGN A retrospective study. METHODS Records of 663 SSNHL patients between January 2008 and January 2019 were retrospectively reviewed, including demographic, comorbid diseases, and hearing recovery. Patients were divided into four groups (complete, partial, slight, and no recovery) according to Siegel's criteria and Chinese Medical Association of Otolaryngology (CMAO) criteria. Multinomial logistic regression was performed to evaluate the effects of onset of treatment, initial hearing threshold, audiogram pattern, diabetes mellitus, SLE, and RA on the prognosis of SSNHL according to both criteria. RESULTS Patients in complete recovery, partial recovery, slight recovery, and no improvement were 95 (14.3%), 183 (27.6%), 170 (25.6%), and 215 (32.4%) by Siegel's criteria, and 90 (13.6%), 152 (22.9%), 188 (28.4%), and 233 (35.1%) by CMAO criteria, respectively. Among the four groups, onset of treatment, initial hearing threshold, diabetes mellitus, SLE, RA, and profound audiogram pattern were found to be associated with recovery outcome by both Siegel's criteria and CMAO criteria (P < .05). According to analysis results, presence of SLE, RA, diabetes mellitus and higher initial hearing threshold were significantly correlated with a poor prognosis by both Siegel's criteria and CMAO criteria (P < .05). CONCLUSION Comorbid SLE or RA may negatively affect the prognosis of SSNHL. Lower initial hearing threshold and absence of diabetes mellitus are associated with favorable hearing recovery.

Abstract
BACKGROUND T cell therapy for cancer involves genetic introduction of a target-binding feature into autologous T cells, ex vivo expansion and single large bolus administration back to the patient. These reprogrammed T cells can be highly effective in killing cells, but tumor heterogeneity results in regrowth of cells that do not sufficiently express the single antigen being targeted. We describe a cell-based therapy that simultaneously targets multiple tumor-specific antigens. METHODS High-affinity polyclonal rabbit antibodies were generated against nine different surface-related tumor-specific mutations on B16F10 cells. Unsorted splenic effector cells from syngeneic mice were incubated with a cocktail of the nine anti-B16F10 antibodies. These 'armed' effector cells were used to treat mice previously inoculated with B16F10 melanoma cells. RESULTS The cocktail of nine antibodies resulted in dense homogeneous binding to histological sections of B16F10 cells. Five treatments with the armed effector cells and PD1 inhibition inhibited tumor growth and improved survival. Shortening the interval of the five treatments from every three days to every day increased survival. Arming effector cells with the four antibodies showing best binding to B16F10 cells even further increased survival. CONCLUSIONS This study demonstrates that ex vivo arming a mixed population of immune effector cells with antibodies targeting multiple tumor-specific mutated proteins in conjunction with PD1 inhibition delayed tumor growth and prolonged survival in mice inoculated with an aggressive melanoma. A remarkably low total antibody dose of less than 5 µg was sufficient to accomplish tumor inhibition. Scaling up to clinical level may be feasible.

Abstract
Fibroblast growth factor receptor 2 ( FGFR2) in craniofacial bones mediates osteoprogenitor proliferation, differentiation, and apoptosis. The distortion of proper craniofacial bone growth may cause class II and class III skeletal malocclusion and result in compromised function and aesthetics. Here, we investigated the association between variations in FGFR2 and skeletal malocclusions. First, 895 subjects were included in a 2-stage case-control study with independent populations (stage 1: n = 138 class I, 111 class II, and 81 class III; stage 2: n = 279 class I, 187 class II, and 99 class III). Eight candidate single-nucleotide polymorphisms (SNPs) in FGFR2 were screened and validated. Five SNPs (rs2162540, rs2981578, rs1078806, rs11200014, and rs10736303) were found to be associated with skeletal malocclusions (all P < 0.05). That is, rs2162540 was significantly associated with skeletal class II malocclusion, while others were associated with skeletal class III malocclusion. Electrophoretic mobility shift assay and chromatin immunoprecipitation analysis showed that the common genotypes of rs2981578 and rs10736303 contained the binding sites of RUNX2 and SMAD4. Compared with the common genotypes, the minor genotypes at these 2 SNPs decreased the binding affinity and enhancer effect of RUNX2 and SMAD4, as well the levels of FGFR2 expression. In addition, FGFR2 expression contributed positively to osteogenic differentiation in vitro. Thus, we identified FGFR2 as a skeletal malocclusion risk gene, and FGFR2 polymorphisms regulated its transcriptional expression and then osteogenic differentiation.

Abstract
Background p66Shc, a Src homologue and collagen homologue (Shc) adaptor protein, mediates oxidative stress signaling. The p66Shc-null mice have increased lifespan and enhanced resistance to oxidative stress. Studies have also indicated its potential role in inner ear aging, which can lead to deafness. Objective The aim of this study was to determine the effects of p66Shc down-regulation on the marginal cells (MCs) of the inner ear stria vascularis. Methods Primary MCs were isolated from neonatal rats and treated with glucose oxidase to induce oxidative stress. The cells were transduced with adenovirus expressing siRNA, and the knockdown was verified by Western blotting. The reactive oxygen species (ROS) levels and apoptosis were analyzed using the DCFH-DA probe and Annexin-V/7-AAD staining respectively. The ultrastructure of the differentially-treated cells was examined by transmission electron microscopy (TEM). Results: The in vitro oxidative stress model was established successfully in rat MCs. Knockdown of p66Shc alleviated the high ROS levels and apoptosis in the glucose oxidase-treated cells. In addition, glucose oxidase significantly increased the number of peroxisomes in the MCs, which was decreased by p66Shc inhibition. Conclusion Oxidative stress increases p66Shc levels in the marginal cells of the inner ear, which aggravates ROS production and cellular injury. Blocking p66Shc expression can effectively reduce oxidative stress and protect the MCs.

Abstract
Giant cell reparative granuloma (GCRG) is a type of non-neoplastic lesion that can be rarely found in clinical practices. Due to the lack of specificity in symptoms, signs and auxiliary examinations, it is likely to be misdiagnosed, and thereby affecting the treatment and prognosis. In July 2018, a GCRG patient who was described with "4 years of hearing loss in the left ear, accompanied by 2 months of preauricular swelling" as the first symptom was admitted in our hospital. Both the HRCT and MRI scans for the temporal bone suggested the presence of tumor at the left lateral skull base, but the nature still needed further examination. Intraoperatively, the tumor was completely removed and repaired locally. Pathological examination confirmed the symptoms as GCRG. Immunohistochemistry showed the expression of CD68 and CD163 in the tumor cells. Postoperatively, the patient recovered well without complications, and had the stitches removed before being discharged on schedule.

Abstract
Objective:This study was to analyze the results of video head impulse test (vHIT) of benign paroxysmal vertigo of childhood (BPVC) in order to determine the potential value of vHIT in the diagnosis and treatment for BPVC and to discuss its possible pathogenesis of BPVC. Method:Thirty-six children with BPVC were enrolled. No hearing loss and skull abnormality were found in these children as assessed by pure tone audiometry, acoustic impedance, CT or MRI scan. The vHIT was carried out, and main outcome measures were the gain of vestibulo-ocular reflex, gain asymmetry, and refixation saccades. Eleven healthy children were selected as normal control who came to our hospital for doing a routine checkup and have no history of dizziness. The differences of vHIT results between these two groups were analyzed. Result:①The vHIT results in control group were normal. In all BPVC subjects, abnormalities were detected in 9 patients (25.0%),including vHIT gains decline in 3 patients, abnormal symmetry in 4 patients, and abnormal isolated overt saccades in 2 patients.②The average saccadic gain in different canals of BPVC group was 1.03±0.14, 1.01±0.15, 1.13±0.31, 1.18±0.36, 1.21±0.33, 1.14±0.30 in left horizontal, right horizontal, left anterior, right posterior, right anterior, left posterior canal, respectively; while in normal group, it was 1.14±0.15, 1.18±0.09, 1.16±0.30, 1.18±0.40, 1.34±0.26, 1.30±0.20, respectively. Significant statistical difference was found only in horizontal canals between these two groups (P<0.05). ③Asymmetry of the three pairs of conjugated semicircular canals was 0.04±0.07 (horizontal canal), 0.06±0.04 (left anterior and right posterior canal), 0.06±0.04 (right anterior and left posterior canal) in BPVC group, respectively; while in control group, it was 0.02±0.02, 0.04±0.03, 0.04±0.04,respectively. There was no statistical difference between the two groups (P>0.05). Conclusion:A certain proportion of abnormal peripheral vestibule function in children with BPVC was found. vHIT is a "child friendly," relatively easytouse, and simple tool to evaluate each of the 6 semicircular canals, which may offer some potential clinical information for assessing the vestibule dysfunction for BPVC.

Abstract
OBJECTIVE To study the ultrasound guiding by methylenum coeruleum thoracic paravertebral block analgesia effect and promote healing of herpes zoster. METHODS A total of 87 patients with herpes zoster were randomly divided into an observation group and a control group, and the two groups received the same treatment including antiviral drug, nerve nutrition, in order to increase the body's resistance. The observation group were given thoracic paravertebral block with methylenum coeruleum guided by ultrasound, recorded visual analogue scale (VAS) of the two groups of patients for their hypersensitivity to pain 1d, 3d, 1 week, 2 weeks, 1 month after treatment, skin lesion healing time, incidence of postherpetic neuralgia (PHN), patients' satisfaction, etc. RESULTS: After administration of thoracic paravertebral block with methylenum coeruleum, VAS of the observation group expectedly decreased. At the same time, the VAS in the observation group was significantly lower than that in the control group, the skin healing time in the observation group was obviously shorter, and the incidence of PHN was lower than that in the control group. The satisfaction of observation group patients was higher than that in the control group (P<0.05). CONCLUSION To implement thoracic paravertebral block with methylenum coeruleum guided by ultrasound can help reduce the degree of hypersensitivity to pain, promoting the healing of herpes zoster could reduce the incidence of PHN, greatly improving patients' satisfaction.

Abstract
Autosomal recessive non-syndromic hearing loss (ARNSHL) is a highly heterogeneous disease involving more than 70 pathogenic genes. However, most ARNSHL families have small-sized pedigrees with limited genetic information, rendering challenges for the molecular diagnosis of these patients. Therefore, we attempted to establish a strategy for identifying deleterious variants associated with ARNSHL by applying proband whole-exome sequencing (proband-WES). Aside from desiring to improve molecular diagnostic rates, we also aimed to search for novel deafness genes shared by patients with similar phenotype, making up for the deficiency of small ARNSHL families. In this study, 48.5% (16/33) families were detected the pathogenic variants in eight known deafness genes, including 10 novel variants identified in TMPRSS3 (MIM 605551), MYO15A (MIM 602666), TMC1 (MIM 606706), ADGRV1 (MIM 602851), and PTPRQ (MIM 603317). Apart from six novel variants with a truncating effect (nonsense, deletion, insertion, and splice-site), four novel missense variants were not found in 200 unrelated control population by using Sanger sequencing. It is important to note that none of novel genes were shared across different pedigrees, indicating that a larger sample size might be needed. Proband-WES is a cost-effective and precise way of identifying causative variants in nuclear families with ARNSHL. This economical strategy may be appropriated as a clinical application to provide molecular diagnostics, genetic counseling, and individualized health maintenance measures for patients with ARNSHL at hearing clinics.

Abstract
OBJECTIVE To evaluate the accuracy and validity of our protocol for prenatal diagnosis and genetic counseling in high-risk families at a clinic. METHODS Fifteen unrelated families with recessive nonsyndromic hearing loss (NSHL) in their family history and a positive attitude towards prenatal diagnosis were recruited in the present study. According to genetic information for each family, Sanger sequencing, fluorescence polymerase chain reaction (PCR)-based congenital deafness gene detection kit and multiple PCR-based target gene capture and high-throughput sequencing were used. Genetic counseling was offered to all participating families by genetic counselors and otologists. Prenatal diagnosis was provided to families with detected pathogenic mutations and who were expected to participate in subsequent prenatal diagnosis. RESULTS In this study, confirmed pathogenic mutations were detected in eight families, who were defined as high-risk families. These families all participated in prenatal diagnosis with positive attitudes. One novel variant (c.1687dupA) in the SLC264 gene was detected in a family. Through genetic counseling, the recurrence probability of NSHL in fetuses was 25% in six families, 0% in one family, and 50% in one family. The results of fetal DNA detection showed that one fetal variant was wild type, three were heterozygous mutations in SLC26A4, and one was a compound heterozygous mutation in SLC26A4. Two variants were heterozygous mutations in GJB2, and one was a homozygous mutation in GJB2. According to the test results for fetal DNA, prenatal diagnosis found that six fetuses had normal hearing, whereas two fetuses suffered from NSHL. After birth, six infants predicted to have normal hearing passed a newborn hearing screening test and two infants predicted to have NSHL were diagnosed with NSHL and received cochlear implants. CONCLUSION Our protocol for prenatal diagnosis and genetic counseling provides detailed information that can assist couples in high-risk families in preparing for infant arrival and future family planning. For the affected neonates, prenatal diagnosis and genetic counseling achieve an "early screening, early diagnosis, early intervention" strategy.

Abstract
OBJECTIVE To investigate the mechanism for the synergistic effect of interferon regulatory factor 4 (IRF4) and microphthalmia-associated transcription factor (MITF) on tyrosinase (TYR) promoter.
Methods: The synergistic transcriptional effect, subcellular localization, and protein-protein interaction for IRF4 and MITF were observed by luciferase assay, immunofluorescence, GST-pull down, and co-immunoprecipitation, respectively.
Results: IRF4 and MITF proteins were co-expressed in the cell nucleus. IRF4 augmented the transcriptional function of MITF (but not the mutant MITF) to activate the expression of the TYR promoter, but with no effect on other MITF-specific target promoters. IRF4 alone did not affect TYR promoter significantly. No direct interaction between the two proteins was noted.
Conclusion: IRF4 and MITF exert a specifically synergistic effect on activation of TYR promoter through IRF4-mediated upregulation of transcriptional function of MITF. This synergistic effect is mainly regulated by MITF; DNA might be involved in the interaction between the two proteins.

Abstract
Vitamin D receptor (VDR) mediates various biochemical activities between the cytoplasm and the nucleus in the cell. The nucleotide-binding, oligomerization domain (NOD)-like receptor family, pyrin domain containing 3 (NLRP3) protein is involved in the T helper type 2 (Th2) response. This study tests a hypothesis that VDR interacts with NLRP3 to restrict the Th2-biased response. In this study, VDR-/- mice and WT (WT) mice were used. Th2 cell differentiation between VDR-/- mice and WT mice was observed. We observed that CD4+ T cell activation was higher in VDR-/- mice. The VDR-/-CD4+ T cells were prone to Th2 polarization. VDR-/- mice produced more immunoglobulin (Ig)E. VDR bound NLRP3 to prevent Th2 differentiation by restricting IL4 gene transcription. Th2 biased inflammation spontaneously developed in the intestine of VDR-/- mice. In conclusion, VDR binds NLRP3 to restrict IL4 gene transcription and prevent biased Th2 polarization.

Abstract
Objective:To explore the detection approach and aetiology of single-side deafness(SSD) in children and provide evidence for diagnoses and treatment. Method:A retrospective study was performed. Medical history and radiological data of children with unilateral deafness were analyzed. Result:The mean age at diagnosis was 6 years old. The mean age at diagnosis was 7.7 month because of failure of universal newborn hearing screening. Inner ear malformations were identified in 80.6% of cases. Cochlear nerve deficiency(CND) was observed in almost 77.8% of our cases, accounts for 96.6% in children with inner ear malformations. Conclusion:The children with SSD could be early detected by UNHS. CND is the main aetiology for SSD. MRI should be the first image choice when SSD children was diagnosed.
