Objective To explore the possible anti-inflammatory mechanism of intensive insulin therapy （IIT） by studying the effect of IIT on the levels of TNF-α, IL-6, C-reactive protein （CRP） and APACHE Ⅱ score in biliary pyemia. Methods Twenty eight patients with biliary pyemia who were admitted by our department and given an operation within 24 h form Jan. 2005 to Dec. 2008 were randomly divided into two groups by using random number table numbers: one group treated with IIT （IIT group, n=14） and another group treated with routine insulin therapy （RIT group, n=14）. The inflammatory factors, such as TNF-α, IL-6 and CRP were detected dynamically and the APACHEⅡ score was calculated. ResultsThe level of CRP and APACHEⅡ score on day 5 and 7 and the levels of TNF-α and IL-6 on day 3, 5 and 7 after operation in IIT group were significantly lower than those in RIT group （P＜0.05, P＜0.0１）. Compared with preoperative levels, the IL-6 and APACHEⅡ score in IIT group commenced to decrease on day 3 after operation （P＜0.05）, that was earlier than control group. Conclusion The treatment with IIT can suppress the composition of TNF-α, IL-6 and CRP, protect impaired hepatic cells, and reduce APACHEⅡ score, the degree of systemic inflammation and incidence of MODS.
Objective To study the clinical significance of total gastrectomy in treatment for gastric cardia cancer.Methods The clinical data of 118 patients with gastric cardia cancer underwent operation from May 1997 to October 2012 in the Department of General Surgery of Baiyin Hospital， Affiliated to Lanzhou University were analyzed retrospe-ctively. Among these 118 patients， there were 65 patients treated by total gastrectomy （total gastrectomy group） and 53patients treated by proximal gastrectomy （proximal gastrectomy group）. The postoperative complications， survival rate，quality of life， and nutrition indexes were compared after operation between the total gastrectomy group and the prox-imal gastrectomy group. Results ① The incidence of postoperative complications was 7.7% （5/65） and 13.2% （7/53） in the total gastrectomy group and the proximal gastrectomy group， respectively， the difference was not statistically signi-ficant （χ2=0.972， P=0.248）. ② 1-， 3-， and 5-year survival rate after operation were 63.1%， 46.2%， and 30.8% in thetotal gastrectomy group；which were 66.0%， 36.9%， and 18.5% in the proximal gastrectomy group. The difference of 1-year survival rate after operation was not statistically significant in two groups （χ2=0.193， P=0.402）， the 3- and the 5-year survival rates of the total gastrectong group were significantly higher than those of the proximal gastrectony group （χ2=4.508， P=0.022；χ2=30.271， P=0.000）. ③ The Spitzer quality of life score had no difference at the different timeafter operation in two groups （P＞0.05）. Compared with the proximal gastrectomy group， the points of heartburn， swallo-wing problem， appetite， and food intake on 12 months after operation in the total gastrectomy group were higher （P＜0.05）， the points of the other indexes had no significant differences （P＞0.05）. ④ The nutrition indexes after operationhad no differences at the different time after operation in two groups （P＞0.05）. Conclusions Total gastrectomy in treatment for gastric cardia cancer would not increase complications， also can improve 5-year survival for patients withⅠ-Ⅲ stage， and survival condition after operation is also much better than that of proximal gastrectomy.
