慢性乙型肝炎患者肝血管炎症与肝脏微循环障碍的关系

The relationship between inflammation of blood vessels and microcirculation disturbance in liver of patients with chronic hepatitis B

目的 研究慢性乙型肝炎患者肝血管炎症与微循环障碍的关系. 方法 采用光镜和电镜观察188例慢性乙型肝炎肝活检组织,根据血管炎症程度进行分级,探讨肝血管炎症与微循环障碍的关系. 结果 188例慢性乙型肝炎患者中,肝血管炎症1级67例,2级89例,3级32例.肝窦腔狭窄率、肝窦腔阻塞率、肝窦腔内微血栓形成率、肝窦内皮细胞窗孔减小、减少率、狄氏腔内胶原形成率及基底膜形成率均随肝血管炎症加重而升高. 结论 慢性乙型肝炎肝血管炎症是肝组织微循环障碍的重要原因,改善肝组织微循环治疗的同时,必须进行抗炎治疗.

Objective To study the effects of inflammation of blood vessels to microcirculation disturbance in liver of patients with chronic hepatitis B（CHB）. Methods 188 cases of hepatic tissue with CHB were observed by light microscope and electronmicroscope.They were graded according to the inflammation of blood vessels in liver,and to discuss the relationship between the inflammation of blood vessel and microcirculation disturbance. Results According to the inflammation of blood vessels in liver,188 cases of CHB were divided to 3 grades,67 cases in grade 1,89 cases in grade 2 and 32 cases in grade 3.The rate of hepatic sinusoidal stenosis,hepatic sinusoidal blockage,the formation of microthrombus,decreased sizes and reduced numbers of sinusoidal endothelial cells＇ penestrate,the formation of collagen in Disse＇s spaces and the formation of basilar membrane increased along with the aggravation of inflammation of hepatic blood vessels. Conclusion Inflammation of hepatic blood vessels was an important factor on microcirculation disturbance in liver of patients with CHB.It should be done something to improve the microcirculation,and decrease inflammation at the same time.
