Abstract
OBJECTIVE We aimed to explore the prognostic value of Septin9 DNA methylation in breast cancer. METHODS Breast cancer patients with and without recurrence or metastasis and matched non-breast cancer patients were screened retrospectively from 2014 to 2016. Bisulfite conversion and fluorescence quantitative methylation-specific polymerase chain reaction were used to detect the Septin9 methylation status and distribution levels in patient breast tissues. RESULTS Septin9 DNA methylation was more frequent in breast cancer tissues than in non-breast cancer tissues, but was not significantly correlated with any relevant breast cancer patient clinicopathological characteristic. Septin9 methylation rates were higher in patients with recurrence or metastasis. Septin9 methylation, tumor size, lymph node status, and progesterone receptor (PR) expression could influence prognosis. Septin9 methylation was significantly associated with worse disease-free survival in breast cancer patients, with receiver operating characteristic curve analysis indicating that it had good prognostic ability, with an area under the curve (AUC) value of 0.719. The AUC values increased when Septin9 methylation was combined with tumor size, lymph node status, and PR to predict prognosis. CONCLUSIONS Septin9 DNA methylation was an independent predictors of breast cancer prognostic risk. This could possibly help improve comprehensive prognosis prediction methods when combined with other risk factors.

Abstract
Objective: To explore the ideal way of using the stereoscopic unequal S-plasty in reconstruction of the congenital hypoplastic ear lobe cleft with soft tissue deficiency. Methods: Data of 10 patients with the congenital hypoplastic ear lobe cleft associated with soft tissue deficiency who were treated using the stereoscopic unequal S-plasty in the plastic cosmetic surgery of Xuzhou Central Hospital from Aug 2018 to Aug 2022 were retrospectively analyzed. Six patients were male, 4 were female. Their ages ranged from 6 years to 19 years old, with a mean age of 13 years. Lobe deficiency size ranged from 0.8 cm×0.5 cm to 1.2 cm×1.0 cm. Results: The post-operation flaps had no venous congestion, infection or necrosises. During 3 to 12 months of follow-up, the technique made the shape of the ear lobe smoother. The incisions left inconspicuous scars. The result was satisfactory in terms of matching the contralateral normal ear lobe in shape and symmetry. Doctors and patients were satisfied with the results. Conclusions: The stereoscopic unequal S-plasty is an effective way to correct the the severe congenital ear lobe deformity. The good result,simple manipulation and short operation time are the advantages of this method.

Abstract
Objective: To summarize and popularize the application of temporalis muscle flap in repair and reconstruction after the resection of tumor or necrotic foci following radiotherapy of nasopharyngeal carcinoma (NPC). Methods: A retrospective analysis was made on the patients treated in the Department of Otorhinolaryngology Head and Neck Surgery of Xiangya Hospital between January 2019 and March 2021 who underwent surgical resection of tumor or necrosis of NPC after radiotherapy and temporalis muscle flap repair. The effect of the repair and the patients' postoperative conditions were analyzed. Results: A total 29 patients, 19 males and 10 females, aged from 33 to 65 years old, were included in the study, and were followed up for 6-35 months. Except for 2 patients who were not followed due to bleeding or special bacterial infection, the others' temporalis muscle flap healed well and no cerebrospinal fluid rhinorrhea or massive hemorrhage occurred. After the operation, all patients had no nasopharyngeal reflux or new open rhinolalia, and in some patients, the open rhinolalia even got relieved. Except for one case of depressed temporal fossa caused by infection and followed debridement and another one case of shallowed forehead wrinkles, the appearances of the other patients were basically symmetrical. Some patients had temporary mouth opening limitation after operation, and all of them recovered after rehabilitation exercises. Conclusions: The temporalis muscle flap can protect the skull base and internal carotid artery, and improve the quality of life of patients after the resection of NPC or necrotic foci. It is a reliable pedicled flap for repairing skull base defect with simple operation procedures and relatively few complications.

Abstract
Objective: To investigate the diagnosis and surgical treatment of patients with soft tissue necrosis of cranial base after radiotherapy for nasopharyngeal carcinoma (NPC). Methods: The clinical data of 7 NPC patients with soft tissue necrosis but not bone necrosis after radiotherapy were retrospectively analyzed.They were treated in Xiangya Hospital from 2015 to 2019. The clinical manifestations, diagnosis, treatment and prognosis were analyzed. The major clinical symptoms of the 7 patients were headache in 7 cases, hearing loss in 7 cases, long-term nasal malodor in 5 cases and epistaxis in 2 cases. All patients underwent high-resolution CT, MR and magnetic resonance angiography (MRA) before operation. All cases were treated with extended transnasal endoscopic approach under general anesthesia for resection of necrotic tissue. Five cases had their affected cartilaginous segments of the eustachian tubes partially or completely resected, 7 cases were treated with myringotomy and tube insertion, and 1 case was treated with pansinusectomy. Anti-inflammatory treatment were carried out during the perioperative period. The recovery of patients was observed and recorded through regular follow-up (from 6 months to 3 years) after the operation. Results: Nasopharynx soft tissue lesions can be seen in seven patients with bone cortex integrity by CT, and small bubble shadow can be seen at junction area between skull base soft tissue lesions and skull base bone surface.MR and MRA examination showed extensive inflammatory changes of nasopharynx. Parapharyngeal irregular necrotic cavity was found in 6 cases without central enhancement, demonstrating edema of surrounding soft tissue. The necrotic tissue of all 7 patients was surgically removed. Postoperative pathological examinations confirmed that all of them were necrotic soft and cartilaginous tissue, without tumor recurrence. The symptoms of all patients were significantly alleviated after operation. Headache was cured in 5 cases and relieved in 2 cases. Nasal malodor was cured in 4 cases and alleviated in 1 case. During the follow-up period, 5 patients survived, and 2 patients who had their eustachian tube reserved died. One of them died of nasopharyngeal hemorrhage caused by recurrent nasopharyngeal necrosis 3 months after the operation. Another case died of severe intracranial infection 6 months after operation. Conclusions: The diagnosis of skull base soft tissue necrosis after radiotherapy for nasopharyngeal carcinoma needs comprehensive analysis of radiotherapy history, clinical manifestations and imaging examination. High resolution CT, MR and MRA of skull base are very important for diagnosis. Early active removal of large-scale necrotic lesions under endoscope and partial or total resection of eustachian tube cartilage according to the involvement of eustachian tube cartilage is effective means of controling skull base soft tissue necrosis after radiotherapy. The effective means of necrosis can improve the quality of life of patients.

Abstract
Postoperative bleeding is the most frequent serious complications after vacuum-assisted breast biopsy (VABB). The aim of this study was to evaluate the clinical effect of using urinary balloon catheter to prevent postoperative bleeding after ultrasound-guided VABB. From May 2016 to June 2018, 324 patients who underwent ultrasound-guided VABB were randomized into the study group and control group. In the study group, an urinary balloon catheter was inserted into the excision cavity to prevent bleeding and hematoma. In the control group, compression with thorax pressure bandage was used for hemostasis. Postoperative subcutaneous ecchymosis and hematoma were recorded and compared between the two groups. The rates of postoperative ecchymosis and hematoma in the study group were significantly lower than that in the control group (5.6% vs 13.0%, P < .05; 8.0% vs 20.4%, P < .05). Among patients with lesions ≤1.5 cm, the rates of postoperative ecchymosis and hematoma were 2.9% and 4.3% in the study group, 6.5% and 11.7% in the control group, but there was no statistically significant difference between the two groups (P > .05). Among patients with lesions >1.5 cm, the rates of postoperative ecchymosis and hematoma in the study group were significantly lower than that in the control group (7.6% vs 18.8%, P < .05; 10.9% vs 28.2%, P < .05). Hemostasis with balloon urinary catheter is a safe and effective method to prevent postoperative bleeding after VABB.

Abstract
Abstract
Background: Despite the fact that trastuzumab alongwithotherHER2-targetingdrugshavesignificantlyimprovedthe survival of patients with HER2 overexpression breast cancers (HER2+BC), resistance to trastuzumab is a clinical challenge in HER2+BC. Discerning actionable mechanisms of resistance to trastuzumab remains an important unmet need. WepreviouslyreporteddysregulationofCXCR4involvedintrastuzumab-resistance,butitscausal roleandthe associated mechanismsremainunknown.
Methods We established trastuzumab-resistant (TR) human breast cancer HER2+ cell lines by continuously exposing cells to trastuzumab (20 μg/ml) for at least 6 months. CXCR4 expressionwasassessed in TR cells or parental cells with Westernblot.QuantitativedensitometricanalysisofthedensitywasperformedwithAlphaViewSAsoftware.Relevant cell phenotypes were measured, including mammosphere formation, in vitro antibody-dependent cellular cytotoxicity (ADCC) assay, and cell invasion induced by 10% fetal bovine serum with or without 100ng/ml stromal cell-derived factor-1α (SDF-1α, CXCL12), the ligand of CXCR4. ANOVAwasusedtotest differencesbetweenmorethantwogroups,whilethedifferencesbetweentwogroupswereassessedbasedon pairedt-test.
Results: To better capture the heterogeneity of HER2+BC, we chose two trastuzumab-sensitive cell lines, BT474 (HER2+/HR+) and SKBR3 (HER2+/HR-) and an intrinsically trastuzumab-resistant cell line, HCC1419 (HER2+/HR-). We found much higher CXCR4 expression levels in cells with intrinsically trastuzumab-resistant cells compared to trastuzumab-sensitive cells. Upregulation of CXCR4 expression was found in each of the acquired TR cell lines compared to their parental cells. Dysregulation of CXCR4 significantly enhanced mammosphere formation and cell invasion (P < 0.001, respectively). SDF-1α induced cell invasion and clumping. Down-regulation of CXCR4 with shRNA significantly increased trastuzumab induced–antibody-dependent cellular cytotoxicity (2.17 folds of control cells, P < 0.01). Targeting CXCR4 with its approved inhibitor AMD3100 significantly decreased mammosphere formation and invasion of HER2+BC with TR (P < 0.01; P < 0.0001 respectively).
Conclusion: Our results suggest that the SDF-1-CXCR4 axis plays a critical role in resistance to trastuzumab. Targeting CXCR4 signaling may lead to novel combinational therapies to overcome intrinsic or acquired resistance to trastuzumab in advanced HER2+BC, including postulated effects of trastuzumab on signal transduction, differentiation and immune activation.

Abstract
Mammary ductoscopy (MD) is commonly used to detect intraductal lesions associated with nipple discharge. This study investigated the relationships between ductoscopic image-based indicators and breast cancer risk, and developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge. A total of 879 consecutive inpatients (916 breasts) with nipple discharge who underwent selective duct excision for intraductal neoplasms detected by MD from June 2008 to April 2014 were analyzed retrospectively. A nomogram was developed using a multivariate logistic regression model based on data from a training set (687 cases) and validated in an independent validation set (229 cases). A Youden-derived cut-off value was assigned to the nomogram for the diagnosis of breast cancer. Color of discharge, location, appearance, and surface of neoplasm, and morphology of ductal wall were independent predictors for breast cancer in multivariate logistic regression analysis. A nomogram based on these predictors performed well. The P value of the Hosmer-Lemeshow test for the prediction model was 0.36. Area under the curve values of 0.812 (95 % confidence interval (CI) 0.763-0.860) and 0.738 (95 % CI 0.635-0.841) was obtained in the training and validation sets, respectively. The accuracies of the nomogram for breast cancer diagnosis were 71.2 % in the training set and 75.5 % in the validation set. We developed a nomogram for evaluating breast cancer risk in intraductal neoplasms with nipple discharge based on MD image findings. This model may aid individual risk assessment and guide treatment in clinical practice.

Abstract
Langerhans cell histiocytosis (LCH) is a rare disease ranging from a benign to a rapidly fatal condition affecting young children predominantly, and is characterized by an abnormal clonal proliferation of Langerhans cells. We report a case of a 3-year-old child presenting with a 1-year history of otorrhea and otorrhagia followed by a 6-month history of postauricular swelling in the right ear. Imaging demonstrated a large mass of organized tissue. A biopsy was conducted, and the diagnosis of LCH was confirmed by histopathological and immunohistochemical examination. The child was treated with a 12-month course of vinblastine chemotherapy with prednisolone. No clinical evidence of recurrence was noticed after 3 years of follow-up. This rare case highlights the importance for otolaryngologists to keep LCH in mind for differential diagnosis in very young patients with symptoms and signs suggestive of acute mastoiditis or chronic otitis media.
