目的評價雙吻合器在中、低位直腸癌保肛手術應用中的安全性和實用性。方法分析 38 例應用雙吻合器行結、直腸吻合治療中、低位直腸癌的經驗。結果本組病例在使用雙吻合器中閉合和吻合過程順利、簡捷，術后無1 例發生吻合口漏; 發生吻合口狹窄1例,發生率為2.6%, 經肛門指法擴肛后即痊愈; 局部復發2例,復發率為5.3%。結論雙吻合器吻合法可作為中、低位直腸癌保肛手術的一種安全可靠的術式選擇。
Objective To study the effects of edaravone on the lung injury of severe acute pancreatitis （SAP） in rats. Methods Thirty-six SD rats were randomly divided into three groups: normal control group, model group and edaravone group, and SAP was induced by intraductal administration of 5% sodium taurocholate. Edaravone was given in edaravone group, while normal saline was given in normal control group and model group. After operation 6 h rats were executed, and dry/wet weight (D/W) ratio of lung was counted, and malondialdehyde (MDA) content, superoxide dismutase (SOD) activity in serum and lung were detected, respectively. In addition, the levels of tumor necrosis factor-α (TNF-α), interleukin-1, -6 (IL-1, -6) of serum were detected.Results The MDA contentof serum and lung and the levels of TNF-α, IL-1, IL-6 in model group were markedly higher than those in normal control group and edaravone group, but D/W ratio of lung, SOD activity of serum and lung were significantly lower (Plt;0.05). Conclusion Edaravone can alleviate lung injury of rats caused by SAP.
ObjectiveTo study the preoperative evaluation value of serum tumor markers (CA72-4, CEA, CA199 and CA125) in patients with gastric cancer. MethodsSerum levels of tumor markers (CA72-4, CEA, CA199 and CA125) and clinical pathological data of 70 patients with gastric cancer before operation who underwent surgical treatment in the Gastrointestinal Surgery Department of Second Affiliated Hospital of Kunming Medical University in June 2013 to 2014 June were retrospectively analyzed. ResultsThere were some connection between the concentration of the serum CA72-4 and the tumor diameter, TNM staging, invasion depth, and the number of lymph node metastasis (P < 0.05), between CA199 and tumor size, TNM staging, and invasion depth (P < 0.05), between CEA, CA125 and tumor diameter, TNM staging and distant metastasis (P < 0.05), but the CA72-4, CA72-4, CEA and CA125 had nothing to do with patient' age and gender. ConclusionThe serum tumor markers of CA724, CEA, CA199, and CA125 have clinical application value in preoperative evaluation of gastric cancer.
