Methods 2600 serum samples from chronic hepatitis patients were assayed for fibrosis indexes including HA, PCⅢ, LN and Ⅳ-C with RIA. Liver biopsy was performed in 280 of those patients and the biopsy material was examined histopathologically. The inflammation grade of the liver, stage of fibrosis and degree of chronic hepatitis were recorded and were compared with fibrotic indexes. Results Among 2600 chronic hepatitis patients, every fibrotic index had a significant correlation with the inflammation grade, fibrosis staging and the degree of chronic hepatitis (P<0.01). The coefficient correlation of the results of histopathological examinations to HA was 0.544, 0.548 and 0.468 respectively, that to PCⅢ, 0.495, 0.424 and 0.335, that to LN, 0.214, 0.204 and 0.184, and that to Ⅳ-C, 0.406, 0.404 and 0.412, respectively. Conclusions Serum fibrosis indexes are fairly well correlated with the inflammation grade of the liver, fibrosis staging and the degree of chronic hepatitis. However, as diagnostic markers, they should be considered in combination with liver function tests, ultrasonography and clinical manifestations.展开更多

目前幽门螺杆菌(Helicobacter pylori,Hp)感染的实验诊断技术已日益完善,临床上常用的诊断方法包括细菌形态观察,细菌尿素酶活性测定,血清抗 Hp 抗体测定、细胞 DNA 检测及粪便 Hp 抗原检测.毋庸置疑,经内镜取材的标本进行快速尿素酶试...目前幽门螺杆菌(Helicobacter pylori,Hp)感染的实验诊断技术已日益完善,临床上常用的诊断方法包括细菌形态观察,细菌尿素酶活性测定,血清抗 Hp 抗体测定、细胞 DNA 检测及粪便 Hp 抗原检测.毋庸置疑,经内镜取材的标本进行快速尿素酶试验及组织病理学检查是确诊 Hp 感染的常用方法.但侵入性诊断在某些情况下并不适用,因此血清学检测和尿素呼吸试验等无创性检测方法也具广泛用途,而血清学检测被视为流行病学调查的首选方法.展开更多
文摘目的 探讨一氧化氮(NO)在糖尿病患者食管动力功能紊乱中的作用。 方法 应用PC polygraf HR高分辨多通道测压系统检测糖尿病患者的食管下括约肌压力(LESP)、食管下括约肌长度(LESL)及食管远端蠕动幅度等动力参数;应用Digitrapper MKⅢ动态pH监测仪检测其24h食管内pH各项参数;此外,血清NO含量也被检测。 结果 糖尿病组LESP,LESL均明显低于正常对照组(1.2kPa±0.08kPa vs 2.5kPa±0.3kPa;2.8cm±0.8cm vs 3.5cm±0.6cm,P<0.01,P<0.05),而多峰波及同步收缩波的病理性蠕动发生率则显著高于正常对照组(57.1％ vs 8.3％;21.4％ vs 8.3％,均P<0.01);糖尿病组的食管内24h pH值明显高于正常对照组,糖尿病组血清NO含量显著高于正常对照组(99.3μmol/L±21.4μmol/L vs 76.6μmol/L±18.7μmol/L,P<0.01)。 结论 2型糖尿病患者食管蠕动异常,食管内酸度增加。一氧化氮可能参与糖尿病食管运动功能障碍的发病机制。
