RESUMEN
Objective To explore the expression of RIP2 in colorectal cancer(CRC)tissues,and the inva-sion and migration was observed after RIP2 was increased in CRC cell line.Methods 48 cases of CRC paraf-fin-embedded specimens and 56 cases of tumor-adjacent tissues were collected,and expressions of RIP2 was tested by immunohistochemistry(IHC).pEGFP-RIP2 plasmid and JetPRIME were employed to increase the RIP2 in SW480 cells,and variety of invasion and migration was tested in SW480 cells.Results It was showed that expressions of RIP2 was lower in CRC tumors than in tumor-adjacent tissues(P<0.05).After RIP2 in-creased,migration ability of SW480 cells weakened.Conclusion The expression of RIP2 was decreased in CRC tissues,and it was closely related to tumor cell's invasion and metastasis.
RESUMEN
Objective To analyze the safety and efficacy of early diet after laparoscopic resection of colorectal cancer.Methods A prospective study of 128 patients suffered laparoscopic surgery of colorectal cancer was done in our hospital.According to whether the adoption of early diet program,patients were divided into early oral group (EOF group,n=54)and traditional oral diet group (TOF group,n=74).Age,gender,preoperative nutritional status and other basic factors and postoperative ambulation time, postoperative hospital stay time,the number of cases the use of analgesics,complications of two groups were analyzed statistically. Results The first time of postoperative ambulation time and postoperative hospital stay time of EOF group were significantly re-duced compared TOF group [(1.2±0.8)d vs .(2.5±1.3)d]and [(3.2±1.4)d vs .(5.3±1.6)d](P <0.01).Conclusion Early diet after laparoscopic resection of colorectal cancer is good for patients fast recovery,and postoperative complications of two groups are similar.
