   2. Participated in clinical trials involving any medications or medical devices within 3 months prior to screening, or participated in 3 or more drug clinical trials within the past year;
4. History or evidence of increased risk of sedation or anesthesia, such as cardiovascular disease, respiratory disease, cerebrovascular disease, gastrodintestinal disease and other system disease prior to the screening and/or baseline period;
