Methods Patients with Menire＇s disease were categorized into groups based on hearing and quality of life. Individualized management was provided, including life style modification, drug therapies, endolymphatic sac decompression and labyrin- thectomy. Treatment outcomes were evaluated during up to 24 months follow up. Results Eighty seven patients underwent life style modification and drug therapies. The vertigo control rate of Grade A and B was 76.9% and 83.8% respectively. Six patients received surgical management, including endolymphatic sac decompression （n = 5） and labyrinthecto- my （n = 1）. For these patients, the vertigo control rate of Grade A and B was 80% and 100%, respectively. Conclu- lsions Management of Meni6re＇s disease depends on several factors, i.e. severities of vertigo and hearing loss, quality of life, surgical contraindications and patient subjective desire. The treatment is drug therapies for the majority of patients, as well as life style modification. Surgical indications are rare and the least invasive procedures should be considered first. The results of surgery are generally satisfying.展开更多

The paper finally designed and realized the system based on the. NET platform and Ajax technology. The system uses SQL Server as the background data management system, and in the end using ADO.NET technology to realize data access. According to the actual scientific research management, system design includes integrated office, scientific research institutions, scientific research personnel, research projects and other subsystems, the majority of teachers and the laboratory research team can within the prescribed time limit, in any location by logging into the science and Technology Department of scientific research project management webpage query declaration, provides great convenience for research teachers.展开更多
