目的了解洞庭湖区不同血吸虫病流行环境渔民血吸虫病肝纤维化发生情况。方法用便携式B超诊断仪对3种不同类型环境血吸虫病流行区的911名渔民进行肝实质及门脉纤维化分级诊断,使用Excel和SPSS11.0作统计学分析。结果在3种不同类型环境中,洲垸型和洲岛型男性肝纤维化发生率均高于女性(P均<0.01),但未定居型肝实质纤维化发生率男、女性差异无显著性(P>0.05)。肝实质纤维化发生率依次为:未定居型>洲岛型>洲垸型,而肝门脉纤维化发生率依次为:洲岛型>未定居型>洲垸型。肝实质纤维化发生率洲垸型和洲岛型均以50~60岁年龄组为最高,未定居型以40~50岁年龄组为最高;肝门脉纤维化发生率洲垸型以60~岁年龄组为最高,洲岛型和未定居型均以30~40岁年龄组为最高。结论未定居型及洲岛型渔民肝纤维化程度重于洲垸型,需要加强对未定居型及洲岛型渔民的防治。
Objective To understand the prevalence of liver fibrosis in schistosomiasis among fishermen in different epidemic areas of schistosomiasis in Dongting Lake. Methods 911 fishermen in three endemic areas with schistosomiasis were enrolled in this study. The liver parenchyma and portal fibrosis were diagnosed by portable B-mode ultrasonography. Excel and SPSS11.0 were used for statistical analysis. Results The incidence of liver fibrosis in embankment and island was higher than that in female (P <0.01) in 3 different types of environment, but there was no significant difference in the incidence of unreal hepatic fibrosis among men and women (P> 0.05). The incidence of hepatic parenchymal fibrosis were: unsettled type> Chau Island> Chau embankment, and hepatic portal vein fibrosis were: Island State> Unsettled State Chau Embankment. The incidence of hepatic parenchymal fibrillation continent type and Island Island are the highest in the age group of 50 to 60 years old, not settled to the age group of 40 to 50 years for the highest incidence of hepatic portal vein continent embankment to 60 ~ The highest in the age group, the highest in the 30 to 40 age group is the island islands and undeclared. Conclusions The degree of liver fibrosis in unsettled and island-type fishermen is heavier than in embankment type, and the prevention and treatment of unsettled and island-type fishermen need to be strengthened.
