Objective To design and develop a Information System for Medical Center of Clinical Audiology , (MCCAIS301 ) .Methods The system framework was established by developing software ,constructing user platform and creating database .An implication procedure was also established for clinical use for the MCCA IS301 .The MC-CAIS301 was connected with the Hospital Information System (HIS) in order to connect the equipment in the auditory clinical center and other clinical database system .Results The MCCAIS301 was a new database system for hospital in-formation management specifically designed for audiological tests .It provided an extra functions of the existing HIS system .The MCCAIS301 could store the testing results from more than ten different hearing instruments made from five different companies .The data from the MCCAIS301 could be transferred to the HIS system .The results of the MCCAIS301 could be retrieved and analyzed using the HIS system .MCCAIS301 system had nine sets of standardized hearing testing results ,five output formats and three statistical analyzing functions .Conclusion The MCCAIS301 is an effective information management system which has a strong practical use to improve the efficiency of daily audiology data analysis .The MCCAIS301 using digital technology moves the audiology data analysis from a manual low efficient stage to an effective and intelligent level .

Total 1350 subjects were selected by cluster random sampling from Chongwen District and Shijingshan District in Beijing with a populations of 100 000.Chongwen District represented a typical urban district and Shijingshan represtnted a newly extended urban district.Qualified investigators conducted face-to-face survey using the uniform questionnaire and measurement, dealing with the knowledge, attitude and behavior for risk factors of stroke in two districts.The results showed:in Chongwen District, the awareness rates of "the diagnostic criteria of hypertension", "antihypertensive drugs can lower the risk of cardiocerebral vascular disease", and "criteria for obesity" were 71.3%, 87.3% and 22.9% respectively,which were significantly higher than those in Shijingshan District.The awareness rate of "bad temper may increase the risk of cardiocerebral vascular disease" was lower in the Chongwen District.There were no significant differences in attitude between two districts.In Chongwen District the level of three risk factors (smoking and obesity) was significantly lower than Shijingshan, but action of self-examination was also significantly lower.Generally, there was higher level in health knowledge and lower level of risk factors in Chongwen District.The hypertension-related knowledge and behavior was not entirely consistent.It is necessary to transform knowledge into behavioral changes or intervention of risk factors in population with high awareness like Chongwen District.

In order to improve teachers' teaching ability and manage teachers effectively, we try to organize teachers to carry out a series of activities in the form of "teaching club". We set up six teaching clubs according to the key points of teaching work and teaching hot spots. We explore the formation of "teaching club" as a means of modern teacher management model, through the implementation of the teacher-centered concept, establish an efficient and flexible management system, and establish and improve the active development of behavior and other strategies. Through a period of practice and exploration, we have gained benefits and even made breakthroughs in many aspects, such as the construction of teaching team, curriculum construction and teaching competition. The management strategies mentioned above provide new ideas for the development of teacher management.
