目的:观察比较胃镜下硬化剂注射联合药物治疗和单纯硬化剂注射治疗、药物治疗食管静脉曲张出血的疗效。方法:95例肝硬化并食管静脉曲张出血患者,分成三组。32例患者给予硬化剂注射联合药物治疗,31例患者给予硬化剂治疗,32例患者给予药物治疗。观察三组患者急诊止血率,近期出血率、远期再出血率、曲张静脉消失率、曲张静脉复发率。 结果: 联合组、硬化剂组、药物组急诊止血率分别为93.8%.90.3%、68.8%;联合组、硬化剂组、药物组近期出血率分别为6.3%、9.7%、46.9%;联合组、硬化剂组、药物组曲张静脉消失率分别为90.6%、83.9%、1.9%;联合组、硬化组与药物组急诊止血率、近期出血率、曲张静脉消失率有显著差异。联合组、硬化剂组、药物组远期出血率分别为9.4%、59.4%、31.3%; 联合组、硬化剂组、药物组曲张静脉复发率分别为18.8%、45.2%、87.5%;联合组与硬化组、药物组远期出血率、曲张静脉复发率有显著差异。结论:胃镜下硬化剂注射联合药物治疗食管静脉曲张出血可显著提高疗效。
摘要:目的: 探讨PCNA,VEGF在胃癌组织中的表达关系及其意义。 方法 :免疫组织化学法检测正常胃和胃癌组织中PCNA和VEGF的表达,并分析其与胃癌临床病理特征的相关性。 结果 :胃癌组织中PCNA、VEGF的阳性表达率分别为850%、683%,二者在正常胃组织中均为隐性表达。PCNA的表达与肿瘤分期、淋巴结转移有关(〖WTBX〗P lt;005),而与年龄、性别、肿瘤大小、组织分化程度无关(〖WTBX〗P gt;005);PCNA的表达与肿瘤分期、淋巴结转移有关(〖WTBX〗P lt;005),而与年龄、性别、肿瘤大小、组织分化程度无关(〖WTBX〗P gt;005)。PCNA和VEGF在胃癌中的表达呈正相关。 结论 :PCNA和VEGF在胃癌组织中的高表达促进了胃癌的发生发展。Abstract: Objective: To study the significance and relationship of expression of proliferating cell nuclear antigen(PCNA) and vascular endothelial growth factor (VEGF) in gastric cancer. Methods : The expression of VEGF and PCNA in normal gastric tissues and gastric cancer tissues were detected by immunohistochemistry (SP),and clinic pathological correlation with gastric cancer was analyzed. Results : The positive exression rates of PCNA and VEGF in gastric cancer were 850%、683%, respectively, while negative expression was shown in normal gastric tissues. It was found that the expressions of PCNA and VEGF were both in significant relation to TNM stages and lymph node metastasis (P lt;005), but in no relation to age, gender, diameter of tumor and tumor cell differentiation (P gt;005). The expressions of PCNA and VEGF were positively correlated with each other. Conclusion : It was indicated that the highlevel expressions of PCNA and VEGF might corporately accelerate the progression of gastric cancer.
