The results were compared with acontrol group which consisted of 30 healthy individuals. Endoscopy was performed, and esophageal mucosa biopsieswere taken in all patients. Esophageal manometry was recorded using a four tune water perfused system. The severi-ty of esophagitis, determined by both endoscopy and histology, was related to the amplitude of esophageal perista1ticwaves, in partictilar the cardioesophageal sphincter (CES) dysfunction (P < 0. 01), 24 hour reflux total score. Wehave concluded that the severity of reflux esophagitis is related to the duration of reflux, which in turn is associatedwith the impairment of esophageal body motility and CES dysfunction.展开更多
目的:探讨Pim-3的异常表达在胃癌发展过程中的作用.方法:使用半定量RT-PCR法和免疫组化法检测40例胃癌组织及20例癌旁正常组织标本Pim-3的表达,并比较Pim-3的表达与胃癌临床病理参数的关系.结果:与正常胃黏膜相比,Pim-3mRNA的表达量在...目的:探讨Pim-3的异常表达在胃癌发展过程中的作用.方法:使用半定量RT-PCR法和免疫组化法检测40例胃癌组织及20例癌旁正常组织标本Pim-3的表达,并比较Pim-3的表达与胃癌临床病理参数的关系.结果:与正常胃黏膜相比,Pim-3mRNA的表达量在胃癌组织中更高(0.287±0.058 vs 0.053±0.055,P<0.001).中分化腺癌中Pim-3蛋白的表达高于低分化腺癌组织中的表达,两者比较差异显著(50%vs20%,P<0.05).Pim-3的表达与淋巴转移、静脉转移密切相关(r=0.385,0.412,P=0.014,0.008).结论:Pim-3可作为胃癌早期的生物标志物,并可预示肿瘤的预后.展开更多
目的为了研究内源性一氧化氮(NO)在反流性食管炎粘膜炎症和损伤中的作用.方法对100例胃食管反流性疾病患者进行了内镜、病理、食管测压和食管局部粘膜内 NO 含量的检测.结果 100例反流性食管炎患者内镜诊断为Ⅰ级53例,Ⅱ级27例,Ⅲ级20例...目的为了研究内源性一氧化氮(NO)在反流性食管炎粘膜炎症和损伤中的作用.方法对100例胃食管反流性疾病患者进行了内镜、病理、食管测压和食管局部粘膜内 NO 含量的检测.结果 100例反流性食管炎患者内镜诊断为Ⅰ级53例,Ⅱ级27例,Ⅲ级20例,未见Ⅳ改变;病理轻度(Ⅰ级)改变59例,中重度(Ⅱ级)改变41例;食管测压 LESP≤1.33kPa 11例,1.34-2.66kPa56例,2.67-4kPammHg33例;反流性食管炎粘膜内 NO含量(36±8)mmol.g^(-1)显著高于正常对照组(29±4)mmol.g^(-1)(P<0.01);内镜下反流性食管炎改变为Ⅰ级、Ⅱ级、Ⅲ级者胃粘膜内 NO 含量分别为33.3±4.4mmol.g^(-1)、36.5±5.6mmol.g^(-1)、40.4±6.7mmol.g^(-1),三者之间有显著性差异(P<0.05,0.01);病理轻度和中重度反流性食管炎者粘膜内 NO 含量分别为33.7±4.6mmol.g^(-1)和38.3±5.6mmol.g^(-1),二者之间有显著性差异(P<0.01).结论内源性 NO 不但参与了 LES 压力的调节,而且在反流性食管炎的粘膜炎症和损伤过程中起着重要作用.展开更多
