Objective:To investigate the relationship between symptoms of vertigo and vestibular functions and short-term hearing outcomes in patients with flat descending sudden sensorineural hearing loss （SSNHL）. Methods:A retrospective review was conducted of the vestibular symptoms observed in 48 patients with unilateral flat-down sudden sensorineural hearing loss treated at the Department of Otolaryngology Head and Neck Surgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine. Symptoms of vertigo and the results of cervical vestibular-evoked myogenic potentials （cVEMP）, ocular VEMP （oVEMP）, caloric test and video head-impulse test （vHIT） were collected to determine whether these factors could predict therapeutic efficacy. Results:The symptoms of vertigo was not correlated with prognosis （P>0.05） or with abnormal vestibular functions （P>0.05）. Patients with abnormal cVEMP, oVEMP, caloric test or vHIT showed significantly lower effective rates （32.0%, 44.0%, 32.0%, and 24.0%, respectively）; the greater the number of abnormal tests, the poorer the outcome. Patients with all four tests abnormal gained only （3.13±15.97） dB HL in hearing recovery, whereas those with normal cVEMP, oVEMP, caloric test or vHIT showed better chances of hearing improvements by （29.22±20.31）, （31.18±21.59）, （26.17±21.31）, and （26.38±24.05） dB HL, respectively. Conclusion:Vestibular function effectively predicts prognosis in flat descending SSNHL. Patients with abnormal vestibular tests, regardless of symptoms of vertigo, responded poorly to treatment, whereas those with normal cVEMP, oVEMP, caloric test and vHIT results achieved better hearing recovery. Abnormal vestibular function implies more extensive and severe inner-ear lesions in patients with SSNHL.

Objective:To compare the efficacy of gasless robotic surgery via transaxillary approach and combined axillary-retroauricular approach for unilateral N1b PTC, and to explore the safety and effectiveness of gasless robotic surgery via transaxillary approach for unilateral N1b PTC. Methods:Unilateral N1b PTC patients who underwent surgery in the Department of Otolaryngology, Sun Yat Sen Memorial Hospital, Sun Yat sen University between July 2016 and December 2024 were included and analyzed. According to the inclusion and exclusion criteria and the differences of surgical approaches, the patients were divided into the transaxillary approach（TA） group and the combined axillary-retroauricular approach（TARA） group. The demographic data, operation time, intraoperative blood loss, postoperative drainage volume, postoperative complications, shoulder function evaluation, postoperative visual analogue scale（VAS） of neck aesthetics and recurrence of the two groups were statistically analyzed. Results:A total of 88 patients undergoing gasless robotic surgery were included in this study, including 23 cases in the TA group and 65 cases in the TARA group. The proportion of males in the TA group was significantly higher than that in the TARA group（56.5% vs 21.5%, χ²=9.776, P=0.002）. The total operation time in the TA group was significantly lower than that in the TARA Group（180.00[155.00, 220.00]min vs 220.00[177.50, 272.50]min, z=-2.775, P=0.006）, and the postoperative blood loss in the TA group was significantly lower than that in the TARA Group（30.00[20.00, 50.00]ml vs 50.00[30.00, 60.00]ml, Z=-2.127, P=0.033）. The proportion of area Ⅱ-Ⅴ in the TA group and the TARA group was 87.0% and 70.8%, respectively, and there was no significant difference between the two groups（P>0.05）. There was no significant difference in lateral cervical lymph node dissection and central lymph node dissection between the two groups（P>0.05）. During the follow-up period, no recurrence was found in the two groups, and there was no significant difference in the incidence of complications between the two groups（P>0.05）. According to the stratification of dynamic recurrence risk assessment, it can be seen that the proportion of curative effect satisfaction in the TA group was as high as 95.7%, and that in the TARA group was as high as 81.5%, with no significant difference between the two groups. There was no significant difference in VAS score of neck, Constant Shoulder Score and NDⅡ scale between the two groups（P>0.05）. Conclusion:Gasless robotic surgery via transaxillary approach for unilateral N1b PTC is safe and feasible, and the amount postoperative lymph node acquisition is equivalent to that of combined axillary-retroauricular approach, which can provide a new choice for the treatment of unilateral N1b PTC patients.

Objective:To evaluate the safety, feasibility, and technical advantages of the domestic Jingfeng single-port robotic surgical system in transoral and transaxillary approach surgeries for multisite diseases. Methods:A retrospective analysis was conducted on the clinical data of 6 patients who underwent Jingfeng SP1000 single-port robotic-assisted surgery at our hospital from June 2025 to July 2025. They were divided into the transoral robotic surgery group（4cases） and the transaxillary approach thyroid cancer radical resection group（2cases） based on surgical approaches. The transoral robotic surgery group included extended resection of right tonsillar cancer with cervical lymph node dissection, epiglottic cyst resection, extended resection of right pyriform sinus cancer with cervical lymph node dissection, and surgery for epiglottic cyst and obstructive sleep apnea（OSA）. For each case, parameters including operative time, intraoperative blood loss, perioperative complications, robotic operation performance, and postoperative recovery were recorded. Results:All 6 surgeries were successfully completed without conversion to open surgery or system failure. In the transoral robotic surgery group, the mean robotic operation time was（60.00±34.88） minutes, and the mean intraoperative blood loss was 20.00（5.75，20.00）mL. In the transaxillary robotic surgery group, the robotic operation time was respectively 60.00 and 40.00 minutes, and the intraoperative blood loss was 10.00 and 5.00 mL, respectively. One case of minor perioperative complication（in the flap dissection area） occurred, with no severe complications reported. All patients recovered smoothly after surgery, with a median follow-up of 1.9 months showing no residual lesions, recurrence, or functional impairment. Conclusion:This case series confirms the safety and feasibility of the domestic Jingfeng single-port robot in transoral and axillary approach surgeries in oropharyngeal-head and neck surgery. Its single-port design reduces trauma and the risk of robotic arm collision, adapts to minimally invasive needs, and its domestic production attribute lowers costs to facilitate popularization, providing a new option for such patients.

Objective:To summarize and evaluate the relevant evidence of exercise intervention for adult hemophiliacs patients at home and abroad, and to provide a reference basis for healthcare professionals to individualize exercise programs for adult hemophiliacs.Methods:A computer-based "6s" evidence resource pyramid model was used to systematically search for guidelines, evidence summaries, expert consensuses, systematic reviews and random controlled trials on exercise of adult hemophiliacsin databases such as China Biology Medicine disc, Wanfang Med Online, UpToDate, BMJ Best Practice, PubMed, etc, from the time of creation to January 31, 2023. Quality assessment, evidence extraction and evidence integration of relevant literature was performed by two researchers, with a third researcher adjudicating in case of conflicting opinions. An expert panel meeting was conducted to rate the level of evidence extracted.Results:A total of 15 literatures were included. Among them, 4 guidelines, 2 expert consensuses, 2 systematic reviews, and 7 randomized controlled trials. A total of 28 pieces of best evidence were developed, encompassing 6 aspects of exercise assessment, exercise modality, exercise duration, exercise intensity, precautions, and benefits of exercise.Conclusions:Before exercising, hemophiliacs should be assessed by a multidisciplinary team and an appropriate exercise program should be developed to maintain normal body functions and improve the quality of life of hemophiliacs.

The clinical changes of ulcerative colitis （UC） with the main syndrome of large intestine dampness-heat and the alterations of intestinal flora in UC were summarized to reveal the underlying mechanism. After review of the treatment methods for UC with the syndrome of large intestine dampness-heat， we identified the representative traditional Chinese medicines and compound prescriptions and explored the treatment mechanisms. Furthermore， we probed into the associations of UC and the treatment methods with the intestinal flora. The related articles were retrieved from China National Knowledge Infrastructure （CNKI）. The available studies have shown that Akkermansia muciniphila， Escherichia coli， Enterococcus， and probiotics such as Bifidobacterium and Lactobacillus are closely associated with Chinese medicines in UC patients with the syndrome of large intestine dampness-heat. However， due to the shortcomings in clinical research and the susceptibility of intestinal flora to diverse factors， it is still challenging to accurately characterize the intestinal flora changes associated with diseases. Additionally， the research on the mechanisms of Chinese medicines in regulating intestinal flora in UC patients with the syndrome of large intestine dampness-heat remains to be improved. The feasibility of using Chinese medicines and compound prescriptions for precise regulation of intestinal flora in these patients is still debatable. In this regard， scientific issues such as the biological connotation of UC with the syndrome of large intestine dampness-heat and the correlation between syndrome and intestinal flora have become primary research tasks. Additionally， attention should also be paid to the interactions between the intestinal lumen exposure profile of Chinese medicines and intestinal flora. Finally， the thinking of traditional Chinese medicine （TCM） and the concepts of modern medicine should be combined for the research on the formulation of TCM regimens for regulating intestinal flora in treating UC.

Approach-avoidance conflict(AAC)refers to the internal conflict that individuals experi-ence when faced with conflicting approach or avoidance thoughts.It reveals some characteristics of mental disorders,such as anxiety,depression,and addiction represented by excessive tendencies of approach or avoidance.The function of the cortico-limbic-striatal system influences behavioral choices at the neural level during the onset of AAC,and the development of related behavioral paradigms that can better represent AAC behaviors is critical to evaluating the efficacy of drugs and guiding the development of new drugs.This paper summarizes the neural mechanisms,behavioral paradigms,and applications in behavioral pharmacology related to AAC behaviors from the perspective of psychopharmacology with a view to providing new perspectives and methods for the diagnosis and treatment of related neuro-psychiatric disorders.

Objective To investigate the risk factors of in-hospital mortality and establish a risk prediction model for patients receiving venoarterial extracorporeal membrane oxygenation(VA-ECMO).Methods We retrospectively collected the data of 302 patients receiving VA-ECMO in ICU of 3 hospitals in Guangdong Province between January,2015 and January,2022 using a convenience sampling method.The patients were divided into a derivation cohort(201 cases)and a validation cohort(101 cases).Univariate and multivariate logistic regression analyses were used to analyze the risk factors for in-hospital death of these patients,based on which a risk prediction model was established in the form of a nomogram.The receiver operator characteristic(ROC)curve,calibration curve and clinical decision curve were used to evaluate the discrimination ability,calibration and clinical validity of this model.Results The in-hospital mortality risk prediction model was established based the risk factors including hypertension(OR=3.694,95%CI:1.582-8.621),continuous renal replacement therapy(OR=9.661,95%CI:4.103-22.745),elevated Na2+ level(OR=1.048,95%CI:1.003-1.095)and increased hemoglobin level(OR=0.987,95%CI:0.977-0.998).In the derivation cohort,the area under the ROC curve(AUC)of this model was 0.829(95%CI:0.770-0.889),greater than those of the 4 single factors(all AUC<0.800),APACHE Ⅱ Score(AUC=0.777,95%CI:0.714-0.840)and the SOFA Score(AUC=0.721,95%CI:0.647-0.796).The results of internal validation showed that the AUC of the model was 0.774(95%CI:0.679-0.869),and the goodness of fit test showed a good fitting of this model(χ2=4.629,P>0.05).Conclusion The risk prediction model for in-hospital mortality of patients on VA-ECMO has good differentiation,calibration and clinical effectiveness and outperforms the commonly used disease severity scoring system,and thus can be used for assessing disease severity and prognostic risk level in critically ill patients.

Objective: To under the prevalence of malnutrition and its associated factors in school aged children with cerebral palsy, so as to provide a basis for relevant departments to formulate targeted policies. Methods: From July to August 2023, the researchers selected 333 children with cerebral palsy and 960 children with other diseases aged 6-18 years who were residents of a social welfare institution in Guangzhou, China. Their height and weight were measured and a nutritional status analysis was carried out using a cluster sampling method. Multivariate Logistic analysis was performed to analyze the relative factors and malnutrition status of school aged children with cerebral palsy. Results: The prevalence of growth retardation among school aged children with cerebral palsy was 74.5%, with rates of stunting, normal nutrition status, and overweight/obesity being 17.7%, 7.2%, and 0.6%, respectively. The results of the univariate analysis revealed statistically significant differences in the detection rate of malnutrition among school aged children with cerebral palsy based on gender, gross motor function classification system (GMFCS) grading, and the presence of swallowing disorders ( χ 2=6.02, 15.23, 32.16, P <0.05). The results of the multivariate Logistic regression analysis showed that gender ( OR=0.37, 95%CI =0.15-0.91), dysphagia (OR=4.10, 95%CI =1.39-12.12), and GMFCS classification ( OR=1.45, 95%CI =1.04-3.01) were influencing factors of malnutrition ( P <0.05). Conclusions The detection rate of malnutrition among children and adolescents with cerebral palsy in welfare institutions was found to be relatively high, and influenced by various factors. Corresponding nutritional interventions should be developed and implemented based on the risk factors of malnutrition in school aged children with cerebral palsy to improve their nutritional status.
