ABSTRACT
Objective To explore the curative effect of triple lumen feeding tube on upper gastroin-testinal tract perforation after endoscopic operation.Methods A total of 1 12 patients with upper gastrointes-tinal perforation after endoscopic operation were involved in this prospective control test.The remission rate of abdominal pain and abdominal distension,gastric pH,lesion healing time,length of stay and the success rate of conservative treatment were compared between the control group (indwelling traditional gastric tube and intravenous use of omeprazole injection)and the experimental group (intestinal administration of PPI through triple lumen feeding tube).Results The remission rate of abdominal pain of the experimental group was 61. 3% at 6 hours,and 83. 2% at 12 h,which were significantly higher than those of the control group (P0. 05 ).Con-clusion The curative effect of triple lumen feeding tube on upper gastrointestinal tract perforation after endo-scopic operation is ideal.
ABSTRACT
Objective:To evaluate the physiological roles of bmp3,bmp4 and bmp7 during the formation of permanent tooth roots in dog. Methods:The expression of bmp3,bmp4 and bmp7 mRNA at different stages of the development of permanent tooth roots was examined by in situ hybridization in 3 dogs aged 12-18 weeks. Results:bmp3 was found in dental sac surrounding the germs at the early stage of tooth root development, and in cementoblasts and periodontal cells at the later stage. bmp4 was found in odontoblasts, dental papilla and osteoblasts. bmp7 positive signals was found only in epithelial cells of root sheath around cervical circulus at early stage, then located in cementoblasts and odontoblasts at later stage. Conclusion:The spatiotemporal expressions of bmp3,bmp4 and bmp7 are widely diverse, indicating that they participate in the regulation of tooth root development.
