Objective To find out research contents and related hot spots concerning motion sickness . Methods In the study, Web of Science(WOS) was used as the core data, and the time span of literature retrieval was from its inception to September 30 th, 2017.Research orientation, origins and categories of source data, distribution, rate of citation and types of international cooperation were analyzed by statistical method . Results From the data retrieved from WOS, it could be seen that active research on motion sickness started as early as 1988, and 52 papers were retrieved in 2010 alone, despite that there was some flotation between the years.Research on internal medicine of motion sickness was the most popular , with the amount of retrieved papers being as many as 548 papers.Research on public health, environmental and professional medicine was the research field second only to internal medicine , with the amount of retrieved papers being as many as 323 papers.In the exercise science, motion sickness research was also a hot spot and new research orientation , with the amount of retrieved papers surpassing 300 papers.The journal having the highest amount of published papers concerning motion sickness was "Aviation Space and Environmental Medicine ", with a total amount of published papers being as many as 287 papers.Conclusions Now, the research on motion sickness has become quite mature, and the hot research spot is in internal medicine .

OBJECTIVE To analyze the reason of cause of nosocomial infection of AIDS and the events of medical staff exposed to the virus of HIV,to explore the role of activity in the education program and put in practice the education.METHODS To analyze the activity of education about prevention of nosocomial infection of AIDS and postexposure prophylaxis.RESULTS Having practiced the education,all of medical staffs increased the consciousness to prevent the AIDS,there was not a case of exposed to virus of HIV in the first half of year of 2007.CONCLUSIONS Leaders pay attention to and practice the education activity about NI and prevent the staff from exposure to virus of HIV,especially,to realize a series of rules and counter measures,it is key links to prevent AIDS among medical staffs in hospital.

This paper is about the research on the growth of jyphal body of Hypsizygus marmoreus under the condition of different culture mediums, tempertures, pH, cardon and nitrogen sources. The result shows that Hypsizygus marmoreus can grow on various culture mediums. It grows best on the Culture medium of malt extract agar, but can not grow well on the PDA composite culture medium; the hyphal body can grow well at the temperture of 20—25℃, grows slowly at 10—30℃, but can not grow at 35℃; it can grow when pH is 5 to 8, but the best range of pH is 6.5—7.0; the nutriment assimilation is different with the different sources of carbon and nitrogen, the best carbon source is maltose, best nitrogen source is bacto-peptone.
