    • Effect of Hepatocyte Growth Factor/Scatter Factor on Apoptosis of Colorectal Cancer Cells Induced with Curcumin

      【Abstract】ObjectiveTo explore the effect of hepatocyte growth factor/scatter factor (HGF/SF) on apoptosis of colorectal cancer cells induced with curcumin. MethodsMTT assay was used to evaluate the cytotoxicity of curcumin to colorectal cancer cells. Flow cytometry was used to detect the antiapoptosis effect of HGF. ResultsFlow cytometry showed only 64 μg/ml curcumin could play the proliferationinhibiting role in Caco-2 cells leading to their apoptosis; at the same time, different concentrations of HGF could antagonize this inhibitory effect resulting in the decrease of apoptosis, but HGF worked without a concentration-dependent manner. The study on MAPK pathway showed that the protective effect of HGF on the apoptosis of Caco-2 cells was not influenced by inhibiting p42/p44 MAPK and p38 MAPK pathway. ConclusionHGF/SF antagonizes the apoptosis of Caco-2 cells induced with curcumin, but MAPK signaling pathway might not participate in this process.

    • Relationship Between Serum Hepatocyte Growth Factor and Colorectal Cancer with Hepatic Metastasis

        目的 研究結直腸癌患者血清中肝細胞生長因子(hepatocyte growth factor,HGF)的表達水平及其與結直腸癌肝轉移的關系。  方法 收集我院2006年9月至2009年1月期間手術治療并經病理證實為結直腸癌患者35例,應用夾心ELISA法檢測血清中HGF表達水平。  結果 血清中HGF表達在結直腸癌有遠處轉移者中為(0.37±0.11) ng/ml,明顯高于無轉移者的(0.20±0.06) ng/ml (Plt;0.05); T3、T4期者為(0.32±0.29) ng/ml,亦明顯高于T1、T2期者的(0.20±0.14) ng/ml (Plt;0.05); 肝轉移者為(0.43±0.10) ng/ml,明顯高于其他部位轉移者的(0.31±0.09) ng/ml (Plt;0.05)。  結論 血清HGF水平與結直腸癌發展及肝轉移發生有密切關系,血清HGF水平有望作為監測結直腸癌轉移的臨床指標。

    • Clinical Analysis of Idiopathic Perforation of Colon in Elderly Patients (Report of 28 Cases)

      目的 探討老年患者特發性結腸穿孔的臨床特點。方法回顧性分析我科2000年5月至2010年5月期間收治的28例特發性結腸穿孔老年患者的臨床資料。 結果28例患者中男16例,女12例; 年齡60~87歲,中位年齡69.2歲。所有患者表現為急性腹痛或腹膜炎; 術前5例確診,23例誤診; 均行急診剖腹探查手術,穿孔位于乙狀結腸與直腸交界處有18例,位于降結腸4例,乙狀結腸中段5例,直腸上段1例。 8例行穿孔部位結腸外置,再擇期行二次手術; 16例行乙狀結腸下段及直腸上段切除、結腸造瘺術; 4例行病變部位一期切除吻合、回盲部導管減壓引流術。術后病理報告: 結腸壁局灶性炎性反應壞死,穿孔邊緣清楚,肌層斷裂整齊,黏膜剝脫,其中10例伴黏膜潰瘍。 住院時間為2~4周,平均2.6周。 20例患者痊愈出院,死亡8例,其中4例死于中毒性休克,2例因吻合口漏并發腹腔膿腫死于嚴重感染和多器官功能衰竭,2例死于并發肺部感染、呼吸衰竭。 結論診斷性腹腔穿刺及CT檢查對老年患者的特發性結腸穿孔診斷極為重要,一旦確診或疑診應盡早手術治療。
