Objective To confirm the direct projection pathway between the medial vestibular nucleus (MVN) and vestibular efferent (VE) neurons and explore its electrophysiological characteristics. Methods Newborn [(9±1) day-old] male and female Wistar rats were used in the study. The postsynaptic currents of VE were recorded after stimulating neurons in MVN by the whole-cell patch clamp recording technique. The action potentials (APs) of the afferent neurons in MVN were recorded retrogradely after stimulating the area of VE neurons distribution medial to genu of facial nerve (g7), and the position and shape of the recorded neurons were determined by biocytin staining. Results The resting membrane potentials of VE neurons located medial to g7 ranged between -70 mV and -55 mV in current clamp recordings. Excitatory postsynaptic currents (EPSCs) were recorded in the VE neurons medial to the g7 evoked by single-pulse (0.08 mA, 0.1 Hz, 100 μs) electrical stimulation of MVN. The mean values of amplitude and duration were (195.6±23.7) pA and (23.9±5.9) ms, respectively. APs were recorded in MVN after stimulating the distribution area of VE neurons. CL316243 The mean amplitude of the action potentials was (62.0±4.3) mV, and the mean duration was (94.9±4.7) ms. Biocytin staining indicated that the recorded neurons located in MVN and the axons' terminals went into the area medial to g7 in which VE neurons located. Conclusions There is a direct excitatory pathway projecting from MVN to VE neurons medial to g7. Its physiological function may be related to the feedback regulation of vestibular center to peripheral vestibular afferent signals.Objective To analyze the clinical efficacy of multisensory training and rehabilitation treatment in patients with balance disorders. Methods From January to December 2020, 95 patients with balance disorders in the Vertigo Center of Department of Otorhinolaryngology, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology were enrolled. All patients were treated according to the treatment guidelines of Chinese Medical Association or expert consensus. Those with poor recovery or unsatisfactory treatment results underwent multisensory training and rehabilitation for 1 month after a comprehensive evaluation. The scores of Visual Analogue Scale (VAS), Dizziness Handicap Inventory (DHI), Berg Balance Scale (BBS), and Activities-specific Balance Confidence Scale (ABC), Somatization Symptom Self-Rating Scale (SSS), 9-item Patient Health Questionnaire (PHQ9) and the 7-item Generalized Anxiety Disorder (GAD7) were evaluated and compared before and after the treatment. Results Totally, 95 patients were enrolled. There were 34 males and 61 females, aged (44±14) years. VAS (2.1±1.1 vs 5.9±2.5, P less then 0.01), DHI (15.6±7.7 vs 33.1±13.2, P less then 0.01), SSS (1.5±0.6 vs 2.4±0.8, P less then 0.01), PHQ9 (6.0±2.7 vs 8.6±4.3, P=0.01) and GAD7 (5.2±2.6 vs 9.5±2.8, P less then 0.01) decreased after treatment, while BBS (53.4±10.0 vs 34.8±10.7, P less then 0.01) and ABC (89.6±8.0 vs 55.7±21.8, P less then 0.01) increased. Conclusion Multisensory training and rehabilitation therapy can effectively enhance the vertigo control rate and balance ability in patients with balance disorders, reduce the risk of falling, promote their mental and psychological state, and thus improve the quality of life.Objective To explore the prognosis of individualized vestibular rehabilitation (VR) in patients with intractable vertigo and work out an effective and normative rehabilitation program. Methods A total of 35 patients diagnosed with intractable vertigo who visited Eye & ENT Hospital of Fudan University from September 2017 to December 2019 were enrolled. All the participants consisted of 15 males and 20 females, aged from 24 to 71 years old, and underwent an individualized VR. Follow-ups were conducted at 2 and 4 weeks post-rehabilitation. Assessments consisted of self-rating anxiety scale (SAS), dizziness handicap inventory scale (DHI), activities-specific balance confidence sacle (ABC), computerized dynamic posturography (CDP), and video-electronystagmograph (VNG) were performed. Results SAS, DHI, ABC scores gradually improved after VR. The scores of SAS scale of pre-VR, 2 and 4 weeks post-VR were 41±8, 37±8 and 36±8, respectively. The scores of DHI were 56(40, 78), 46(22, 74), 16(6, 76), respectively. Meanwhile, the scores of ABC were 80±17, 87±11 and 91±9, respectively. There were significant statistical differences of aforementioned three scale scores at different time points (P=0.020, P0.05). The improvement of vestibular function to control balance was statistically significant after 2-and 4-week rehabilitation (both P less then 0.001). The value of directional preponderance was significantly improved after 4-week VR (P=0.007), while no obvious improvement was found after 2 weeks treatment (P=0.593). There was a statistically significant difference in the value of unilateral weakness (UW) between pre-VR and post-VR since 2 weeks (P=0.001). Conclusion Individualized VR in patients with intractable vertigo can not only eliminate anxiety, control dizziness, increase activities of daily life, but also improve the function of vestibulo-spinal and vestibulo-ocular reflex pathways.The disease burden and economic burden of seasonal influenza is substantial in China, and the Coronavirus disease 2019 (COVID-19) pandemic has brought new challenges to the prevention and control of influenza. As a priority group of influenza vaccination, the elderly are at higher risk of influenza-associated severe symptoms and deaths, and they are more price-sensitive vaccine users with better cost-effectiveness of vaccination program. Therefore, a reasonable financing mechanism of influenza vaccination should be designed for the elderly to increase their vaccination rate. This study proposes three financing strategies of influenza vaccination for the elderly in China, trying to explore the distribution of vaccination costs among individuals, central government and local governments under different financing strategies, including the individual-central-local mechanism (strategy 1), the central-local mechanism (strategy 2), and the local payment mechanism (strategy 3). Strategy 1 is feasible and sustainable for most regions in the short term.
