RESUMEN
Objective To investigate the feasibility,safety and clinical efficacy of acute iutestinal obstruction by laparoscopic surgery.Methods We selected 47 patients with acute intestinal obstruction implementation from August 2012 to August 2014,and used laparoscopic surgery on these cases.Results Forty-one cases of laparoscopic surgery were successfully completed,the successful implementation of the enterolysis;due to severe adhesions,laparotomy cannot be separated in three cases;two cases due to intraoperative exploration found in the tumor;one case due to surgery bleeding and laparotomy cannot be completed;no cases with serious complications and no deaths.Conclusion Laparoscopic surgery for acute intestinal obstruction is feasible and safe,with less trauma,quicker recovery,especial ly in the abdominal exploration in significant advantage,it is worthy of further promotion in clinic.
RESUMEN
Type Ⅱ transmembrane serine proteases 4 (TMPRSS4) is a novel type Ⅱ transmembrane serine protease.Present study showed that its expression was related with tumor invasion and metastasis,although its oncogenic significance and molecular mechanisms are still unknown.In this review,the author try to introduce its structure,biological function and mechanism in tumor invasion and metastasis.
