6. Currently there are gastrointestinal diseases such as intestinal obstruction (including incomplete intestinal obstruction) or the researchers determine the patients may cause gastrointestinal bleeding, perforation or obstruction;

7. Within 4 weeks prior to enrollment, there were non-healing wounds, ulcers or fractures;
