Objective To summarize the nursing experience during removing the upper gastrointestinal foreign bodies in special patients by painless endoscopy. Method Retrospective analysis was done to investigate the clinical records on endoscopy for removing the upper gastrointestinal foreign bodies in 69 special patients. Result The foreign bodies in 67 patients were removed by endoscopy successfully, without severe complications such as bleeding and perforation; one patient was removed with duodenum lateral telescope; one patient turned for sugery . Conclusion Sufficient preoperative preparation and skilled surgical nursing cooperation are promising for the successful removal of upper gastrointestinal foreign bodies in special patients.

Objective To explicit the expression and role of miR-26a in gastric cancer tissues, thus to reveal molecular mechanism that miR-26a functions in gastric cancer cells. Methods The qRT-PCR was conducted for detect the ex-pression of miR-26a in 71 cases of gastric cancers. AGS cells were transfected with miR-26a mimics, then Western blot was performed to detect the expressions of MTDH protein. The proliferation ability of AGS cells evaluated by MTT assy. Results qRF-PCR showed that miR-26a was down-regulated 0.44 times in 71 cases of gastric cancer tissues. Western blot showed that the expressions of MTDH protein was inhibited by restored miR-26a or MTDH siRNA in AGS cells. Overexpression of miR-26a or MTDH siRNA inhibited the proliferation of AGS cells. Their OD values of transfected miR-26a mimics and MTDH siRNA were (0.158±0.006),(0.201±0.006) respectively, and their OD values of transfected control were (0.515±0.032),(0.479±0.028) respectively,there were statistically significance(P<0.05). Con-clusion miR-26a suppresses cell proliferation by targeting MTDH in gastric cancer.
