肝硬化是常见疾病之一,约占住院患者1.22%,第一死亡原因是肝性脑病,而血氨增高又是诱发肝性脑病的重要因素[1]。近年来发现,幽门螺杆菌(Ｈｐ)在人群中有较高的感染率,而Ｈｐ在胃内会分解尿素产生大量的氨,这是否会导致肝硬化患者血氨的上升,诱发肝性脑病?我们对此作了研究。材 Cirrhosis is one of the common diseases, accounting for 1.22% of hospitalized patients, the first cause of death is hepatic encephalopathy, and increased blood ammonia is an important factor inducing hepatic encephalopathy [1]. In recent years, it has been found that Helicobacter pylori (Hp) has a high infection rate in the human population, whereas Hp can decompose urea in the stomach to produce a large amount of ammonia. Will this lead to the rise of blood ammonia in cirrhotic patients and induce hepatic encephalopathy? We studied this. material
