  • Role of Apoptosis-Related Gene survivin, caspase-3 and cyclin-B1 in Gastric Carcinoma Tumorigenesis

    【Abstract】ObjectiveTo investigate the role of apoptosis-related gene survivin, caspase-3 and cyclin-B1 in gastric carcinoma by detecting the expressions of survivin, caspase-3 and cyclin-B1 in gastric carcinoma. Methods The expressions of survivin mRNA, caspase-3 mRNA and cyclin-B1 mRNA were determined by reverse transcription-polymerase chain reaction (RT-PCR) method in 30 gastric carcinoma specimens and 10 normal gastric tissue specimens. ResultsThe positive expression rate of survivin mRNA in 30 gastric carcinoma specimens was 66.7%(20/30). While 10 normal gastric tissue specimens did not express survivin mRNA. Although all of 30 gastric carcinoma tissues and 10 normal gastric tissues expressed caspase-3 mRNA and cyclin-B1 mRNA, the expressions of caspase-3 and cyclin-B1 in 20 survivin-positive gastric carcinoma tissues were significantly lower than those of 10 survivin-negative gastric carcinoma tissues (P<0.01) and 10 normal gastric tissues (P<0.01). The expressions of caspase-3 mRNA and cyclinB1 mRNA in 10 survivin-negative gastric carcinoma tissues were significantly lower than those of 10 normal gastric tissues (P<0.01). And in gastric carcinoma tissues the expression of survivin mRNA was negatively related with that of caspase-3 mRNA (r=-0.923,P<0.01) and cyclin-B1 mRNA (r=-0.886,P<0.01), the expression of caspase-3 mRNA was positively related with that of cyclin-B1 mRNA (r=0.892, P<0.01). Conclusionsurvivin enhances gastric tumorigenesis, caspase-3 and cyclin-B1 inhibit gastric tumorigenesis.

  • Experiences on Improved High Ligation and Denudation in Treatment for Simple Varicosis of Great Saphenous Vein

    目的 总结单纯性大隐静脉曲张的治疗经验。方法 回顾性分析我院2007年3月至2009年11月期间采用改进高位结扎及剥脱术治疗单纯性大隐静脉曲张65例患者的临床资料。结果 本组患者手术时间45~127 min,平均54 min。住院时间5~8 d,平均6.8 d。所有切口均甲级愈合,肿胀不适、沉重感等症状消失,切口皮下无出血、瘀血、血肿,无皮肤麻木等并发症发生。术后随访2~33个月,平均26.9个月,无一例发生深静脉血栓形成,均按期拆线,效果良好,无复发。结论 改进高位结扎剥脱术治疗单纯性大隐静脉曲张疗效确切。
