Meniere's disease represents an idiopathic inner ear disorder characterized by endolymphatic hy-drops.Currently,the research methods for identifying genes associated with this disease mainly involve first-genera-tion sequencing and second-generation sequencing.This article reviews research on the genetic study of Meniere's disease,mainly summarizing the candidate genes with repeated pedigree validation in familial Meniere's disease,as well as those frequently reported in sporadic Meniere's disease.

Objective:To investigate the expression of the proinflammatory factor IL-18-mediated NOD-like receptor thermal protein domain associated protein 3/nuclear factor κB(NLRP3/NF-κB)signaling pathway in penile tissues of rats with high-fat diet-in-duced erectile dysfunction(ED),and to explore the intervention effect of sildenafil.Methods:Fifty-five sexually normal male SD rats were randomly divided into 10 cases as the normal control group,and the rest of the rats were fed with high-fat chow to establish the ED rat model,and the successfully screened ED rats were randomly divided into the ED group,the Sil group,the IL-18 group,and the IL-18+Sil group,with 8 rats in each group.Following 14 days of nonstop treatment,the morphological alterations in the penile tis-sue were observed by HE staining.Using immunohistochemistry,the amount and distribution of NF-κB p65 and Adropin in penile tis-sues were found.RT-qPCR was used to identify the expression of NLRP3 and NF-κB p65 mRNA in penile tissues.Western blot exami-nation showed the expression of the proteins NLRP3,pro-IL-18,p-NF-κB p65,NF-κB p65,and Adropin in penile tissues.Results:The ED group showed altered penis tissue morphology,destroyed muscle fibers,enlarged sinus cavity,increased mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18(all P<0.05),and decreased Adropin protein expression(P<0.05).While the protein expression of Adropin was increased(P<0.05),the mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18 in the penis tissues were decreased(all P<0.05)when compared to the ED group.The muscle fibers and sinus cav-ities of the penis were recovered to varying degrees in the Sil group.The IL-18 group experienced the destruction of muscle fibers,an enlargement of the sinus cavity,an increase in the mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18 in the penile tissues(all P<0.05),as well as a decrease in the protein expression of Adropin(P<0.05).The rat penile tissues in the IL-18+Sil group showed variable degrees of recovery in the muscle fibers and sinus cavities when compared to the IL-18 group.Ad-ditionally,there was a drop(all P<0.05)in the expressions of NLRP3,pro-IL-18 m RNA and protein,p-NF-κB p65/NF-κB p65,and p-NF-κB p65 in the penile tissues.The expression of the Adropin protein was elevated(P<0.05).Conclusion:Significant changes have been observed in the NLRP3/NF-κB signaling pathway,which is regulated by IL-18,in the hyperlipidemia ED rat model.In ED rats,sildenafil can increase erectile function by promoting the production of Adropin and blocking the activation of this pathway.

Objective:To investigate the longitudinal relationships among resilience, social support, and negative emotions in college students.Methods:Questionnaire surveys were administered to 1 739 college students from a university in Hebei Province born in the same year in November 2020 and November 2021 respectively, and 1 183 valid responses were finally obtained. The survey battery comprised the 11-item resilience scale, the social support questionnaire, and the 21-item depression anxiety stress scales. Cross-lagged panel analysis was conducted using Mplus 8.3 software. Mediating effects were tested via the Bootstrap method.Results:The scores of resilience, social support and negative emotion at T1 were 58 (51, 65), 57 (51, 66), and 3 (0, 10), respectively. The scores of resilience, social support and negative emotion at T2 were 59 (48, 66), 56 (44, 65), and 11 (1, 24), respectively. Resilience at T1 and T2 were significantly and positively correlated with social support at T1 and T2 ( r=0.66, 0.75, 0.40, 0.33, all P<0.01), while negatively correlated with negative emotion at T1 and T2( r=-0.45, -0.23, -0.26, -0.24, all P<0.01). Social support at T1 and T2 were negatively correlated with negative emotion at T1 and T2( r=-0.44, -0.28, -0.28, -0.28, all P<0.01). T1 resilience significantly and positively predicted T2 resilience ( β=0.35) and T2 social support ( β=0.15). T1 social support significantly and positively predicted T2 resilience ( β=0.07) and T2 social support ( β=0.35), while negatively predicted T2 negative emotion ( β=-0.15). T1 negative emotion significantly and negatively predicted T2 resilience ( β=-0.06) and T2 social support ( β=-0.07). The total effect of T1 resilience on T2 negative emotion was -0.35, and the mediating effect of T2 social support was -0.09, accounting for 25.71% of the total effect. Conclusion:T2 social support partially mediates the relationship between T1 resilience and T2 negative emotions.

Objective To analyze the clinical significance of subjective visual vertical (SVV) tests at different head deflection angles in assessing utricle function in patients with benign paroxysmal positional vertigo (BPPV). Methods A total of 61 BPPV patients who were treated at the Hearing Impairment and Vertigo Diagnosis and Treatment Center of Otolaryngology Head and Neck Surgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from August 2022 to May 2023 were retrospectively included, and 29 healthy adults were selected as controls. SVV tests were performed on all research subjects at different head deflection angles: upright head (0°), left head 45° (L45°), right head 45° (R45°). The test results between the two groups were compared. Results SVV absolute value at R45° in BPPV group was lower than that in the control group (P＝0.003); there was no significant difference in SVV values at 0° and L45° between the two groups. There was no statistical difference in SVV values at different head deflection angles between the control group and the left BPPV group. SVV absolute value at R45° in right BPPV group was lower than that in the control group (P＜0.001); there was no statistical difference in SVV values at 0° and L45° between the two groups. Conclusions SVV test can provide subjective information about the utricle, and SVV tests at different head deflection angles can fine-tune evaluate the function of the utricle in BPPV patients.

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.
