Objective To investigate the expression ofTNF- α mRNA and cytokeratin 20(CK20)mRNA in different tissue of colonic cancer patients, and the relations between the expression and the classify,invasion, as well as Dukes stage of colonic cancer. Methods RT-PCR method was used to detect the ex-pression of TNF-α mRNA and CK20 mRNA in 30 cases of colonic cancer, included cancer tissue,para-cancer tissue and normal tissue. Results The positive rate of TNF- α mRNA expressions in cancer tissue, para-cancer tissue and normal tissue were 70.0%, 43.3% and 20.0%, and the positive rate of CK20mRNA expressions were 63.3%, 33.3% and 16.7%, there were significant difference among the three tissues(P ＜ 0.01 ). But the expression of CK20 mRNA in para-cancer tissue had no significant difference compared with normal tissue (P＞ 0.05). The expression ofTNF- α mRNA was closely correlated with that of CK20mRNA.TNF- α mRNA and CK20 mRNA showed no significant difference in expressing of colonic cancer tissue (P ＞ 0.05 ), but TNF- α was closely correlated with Duke stage and depth of tumor invasion (P ＜ 0.05 ).Conclusion The expression of TNF- α mRNA is objective indicator associated with the invasion of the colonic cancer.

Objective To summarize our experience in diagnosis and treatment of splenic tumors.Methods A retrospective study of the clinicopathologic data of 92 cases of splenic tumor was performed.Results There were 47 benign and 45 malignant tumors.The preoperative confirmed diagnostic rate by B-US was 85.87%(79/92),by CT was 91.30%(84/92).Splenectomy was performed in 81 cases,tumor resection or partial splenectomy in 7 cases,needle aspiration of splenic cyst in 3 cases and biopsy in one case.The 1-,3-,5-,10-year survival rate of malignant tumor was 68.29%,31.70%,14.63%,0.24%,respectirely.Conclusions Imaging studies are the main diagnostic methods of splenic tumors.Splenectomy is the treatment of choice for primary splenic malignant tumor.Splenic benign tumor does not require any other therapy after operation.Splenic malignant tumor requires adjuvant treatment.

Objective:To investigate the effect of different postoperative nutritional support on the gastrointestinal function and nutritional status in acute colon peforation patients.Methods:60 cases of acute emergency operation patients with perforation of the colon,according to the given nutritional support treatment of the different ways,were divided into enteral parenteral joint nutrition (EN + PN) group and total parenteral nutrition (TPN) group.Clinical therapeutic effects of two groups were compared.Results:The results of EN + PN group were significantly better than the those in TPN group (P ＜ 0.05).Conclusion:EN + PN model can improve the postoperative nutritional status and accelerate the recovery of patients with acute colonic perforation.
