  • 简介:上消化道出血临床上以黑便伴有或无呕血及失血症状为主要表现。其病因有消化性溃疡、胃癌、糜烂性胃炎、食道癌、胃底食道静脉破裂出血等。大部后,可达到止血的目的。但有少数患者经上述治疗后持续黑便甚至有呕血,1996—06/2000—12笔者对此类难治性上消化道出血患者7例,在原治疗方案不变的基础上。给予立止血肌注,取得了满意效果。现报告如下。

  • 简介:目的探讨MMP-7(基质溶解素)在结直肠上皮病变的恶性转变中的表达及意义。方法用免疫组化方法检测37例结直肠癌,23例结直肠腺瘤、10例非肿瘤性息肉及10例正常结直肠组织手术标本的石蜡切片中MMP-7的表达。结果37例结直肠癌切片中25例MMP-7为阳性表达(阳性表达率67.6%);23例腺瘤切片中,15例表达阳性,阳性表达率65.2%;10例非肿瘤性息肉中,1例阳性表达,阳性率10%;10例正常结直肠上皮对照均未见表达。结论MMP-7在结直肠上皮病变的恶性变中逐渐增强,在结直肠癌的发生发展中起重要作用。

  • 简介:目的:食管癌是全球发病率及死亡率均较高的消化系统恶性肿瘤,高死亡率的主要原因为食管癌的复发与转移,肿瘤转移抑制基因逐渐成为研究热点,近年来医学领域对肿瘤转移抑制基因的重视与研究也在不断提高与深入,本文主要就常见7种肿瘤转移抑制基因在食管癌中的表达及意义进行分析探讨,为食管癌的临床诊疗提供参考。方法:纳入食管癌癌存档蜡块100例为研究目标,采用免疫组化S-P法检测本组食管癌组织中KISS1/hot7T175、KAI1/CD82、BRMS1、TIP/CC3、Maspin、MKK4、MTSS1蛋白的表达情况,分析其与食管癌转移的关系。结果:食管癌的淋巴结转移与KISS1/hot7T175、KAI1/CD82、Maspin蛋白表达呈负相关性(P<0.05),与MTSS1蛋白表达呈正相关性(P<0.05);与TIP30/CC3、BRMS1、MKK4蛋白表达无关(P>0.05)。食管的远处转移与KISS1蛋白的表达呈负相关性(P<0.05),与MTSS1蛋白的表达呈正相关性(P<0.05),与KAI1/CD82、BRMS1、TIP/CC3、Maspin和MKK4蛋白表达无关(P>0.05)。结论:KISS1/hot7T175蛋白基因可能抑制食管癌的淋巴结转移及远处转移。KAI1/CD82、Maspin蛋白基因可能抑制食管癌的淋巴结转移。MTSS1蛋白基因可能促进食管癌的淋巴结转移及远处转移。
