Objective To compare the effect of different gastrointestinal motility drugs on capsule endoscopy. Methods Seventy-one patients with suspected small bowel disease were randomly divided into metoclopramide group (24 patients), mosapride group(25 patients) and control group (22 group). The patients in metoclopramide group swallowed capsule endoscopy immediately after intramuscularly injecting 10 mg metoclopramide, the patients in mosapride group swallowed capsule endoscopy 15 min after taking 5 mg mosapride, and the patients in control group did not take any of the gastrointestinal motility drugs. Three groups had the same bowel preparation before checking. The finishing rate of small bowel examinations, stomach and small intestinal transit time, intestinal cleanliness and the detection rates of lesions in three groups were compared. Results The total small bowel examination finishing rate was 94.4%(67/71). The small bowel examination finishing rate in metoclopramide group, mosapride group, and control group was 95.8%(23/24), 96.0%(24/25), and 90.9% (20/22), and there was no significant difference(P>0.05). The stomach transit time in metoclopramide group, mosapride group and control group was(27.5 ± 20.7), (28.1 ± 20.9) and (52.3 ± 33.5) min. The stomach transit time in metoclopramide group and mosapride group had no significant difference (P>0.05), but it was significantly lower than that in control group (P<0.05). The small intestinal transit time in three groups had no significant difference (P>0.05). The image class scores in metoclopramide group, mosapride group and control group was (2.5 ± 0.4), (2.7 ± 0.4) and (1.7 ± 0.3) scores.The scores in metoclopramide group and mosapride group had no significant difference (P>0.05), but they were significantly higher than that in control group (P<0.05). The detection rate of lesions in metoclopramide group, mosapride group and control group was 45.8%(11/24), 56.0%(14/25) and 18.2%(4/22). The detection rate of lesions in metoclopramide group and mosapride group had no significant difference (P>0.05), but it was significantly higher than that in control group (P<0.05). Conclusions The use of gastrointestinal motility drugs before capsule endoscopy can improve the quality of inspection, and metoclopramide and mosapride shows no significant difference.

Objective: To investigate the feasibility of chitin as bone substitute material and carrier of rhBMP2.Methods: Porous chitin and chitin/rhBMP2/collagen complex were implanted into calvarial defects in 8 rabbits. Bone repairing ability was assessed by radiographic and histological observation. 2 rabbits without implantation were served as controls. Results: Chitin had certain bone conductive ability. When combined with rhBMP2,a complex possessing both bone conductive activity and bone inductive activity was produced. The complex had greater bone repairing ability than chitin alone. Conclusion: Chitin may be used as a bone substitute material and carrier of BMP. But its mechanical strength and surface activity should be improved.
