ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
Objective To observe the expression of nuclear factor-kappa B(NF-κ3)and monocyte chemnattractant protein-1(MCP-1),and the infiltration of mononuclear macrophage CD68 in lupus nephritis (LN).The association between NF-κB,MCP-1 and MΦ with kidney pathology and clinical manifestations is explored.MethodsNF-κB,MCP-1 and MΦ in renal biopsy specimens from 49 cases of LN were detected using immunohistochemical techeniques.Forty-nine cases of renal tissues were examined for NF-κB by in situ hybridization.The relationship between NF-κB,MCP-1 and MΦ with kidney pathology and clinical manifestations were analyzed.Results ①Compared with the control group ,the expression of NF-κB,MCP-1 and MΦ in LN was significantly higher(P＜0.01).The expression of MCP-1 positively correlated with MΦinfiltration and NF-κB(P＜0.01)in glomeruli and renal tubule and renal interstitium of LN.The expression of NF-κB,MCP-1 and the infiltration of MΦ in LN Ⅳ was significandy higher than non LN Ⅳ and the control group(P＜0.01,P＜0.05).There was no significant difference between renal NF-κB positive group and negative groups in the degree of the immunohistochemical and in situ hybridization examination(P＞0.05).②The histological activity index,urine protein volume(24 h)and serum creatinine in LN were significantly higher than the control group(P＜0.01),and the expression of NF-κB in LN was correlated with histological activity index,urine protein volume(24 h)and serum creatinine(P＜0.01,P＜0.01,P＜0.05).MCP-1 and CD68 expression in LN were correlated with histological activity index and urine protein volume(24 h),but not correlated with serum creatinine(P＞0.05).Conclusion NF-κB induced MΦ by activating MCP-1 may be one cause of kidney injury of LN.NF-κB signal pathway may act as a new therapeutic target for MΦinfiltration and proliferation inhibition in kidney.
