  • 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.

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

    目的 探讨老年患者特发性结肠穿孔的临床特点。方法回顾性分析我科2000年5月至2010年5月期间收治的28例特发性结肠穿孔老年患者的临床资料。 结果28例患者中男16例,女12例; 年龄60~87岁,中位年龄69.2岁。所有患者表现为急性腹痛或腹膜炎; 术前5例确诊,23例误诊; 均行急诊剖腹探查手术,穿孔位于乙状结肠与直肠交界处有18例,位于降结肠4例,乙状结肠中段5例,直肠上段1例。 8例行穿孔部位结肠外置,再择期行二次手术; 16例行乙状结肠下段及直肠上段切除、结肠造瘘术; 4例行病变部位一期切除吻合、回盲部导管减压引流术。术后病理报告: 结肠壁局灶性炎性反应坏死,穿孔边缘清楚,肌层断裂整齐,黏膜剥脱,其中10例伴黏膜溃疡。 住院时间为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例因吻合口漏并发腹腔脓肿死于严重感染和多器官功能衰竭,2例死于并发肺部感染、呼吸衰竭。 结论诊断性腹腔穿刺及CT检查对老年患者的特发性结肠穿孔诊断极为重要,一旦确诊或疑诊应尽早手术治疗。

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

      目的 研究结直肠癌患者血清中肝细胞生长因子(hepatocyte growth factor,HGF)的表达水平及其与结直肠癌肝转移的关系。  方法 收集我院2006年9月至2009年1月期间手术治疗并经病理证实为结直肠癌患者35例,应用夹心ELISA法检测血清中HGF表达水平。  结果 血清中HGF表达在结直肠癌有远处转移者中为(0.37±0.11) ng/ml,明显高于无转移者的(0.20±0.06) ng/ml (Plt;0.05); T3、T4期者为(0.32±0.29) ng/ml,亦明显高于T1、T2期者的(0.20±0.14) ng/ml (Plt;0.05); 肝转移者为(0.43±0.10) ng/ml,明显高于其他部位转移者的(0.31±0.09) ng/ml (Plt;0.05)。  结论 血清HGF水平与结直肠癌发展及肝转移发生有密切关系,血清HGF水平有望作为监测结直肠癌转移的临床指标。
