ABSTRACT
ObjectiveTo study the diagnostic method of microcirculation disturbance of patients with chronic hepatitis B (CHB).Methods81 patients with CHB and 5 normal volunteer were observed.Hypoxia-induciable factor was detected by immunohistochemistry stain,TXB2 and 6-Keto-PGF1α were detected by chemiluminescence and HA was detected by RIA,ultrastructure of liver was observed by transmission electron microscope (TEM).ResultsAccompany with the pathological changes of liver in patients with CHB,the strength and range of expression of HIF-1 α enhanced,HA and TXB2 of serum rised gradually( all P ＜ 0.05 ),but 6-Keto-PGF1α of blood plasma fell- off.The electron microscope showed that erythrocyte aggregation,stenosis and blockage of sinus hepaticus turned obviously,collagen fibers deposition and basal membrane formation aggravated gradually.ConclusionAssociated detec tion with HIF-1 α、HA 、TXB2 and 6-Keto-PGF1 α can reflect the condition of microcirculation of liver perfectly.
ABSTRACT
Objective To explore the relationship between the expression of Hypoxia-induciable factor-1α (HIF-1α) and changes of hepatitis microcimulation in patients with chronic hepatitis B (CHB).Methods 120 patients with CHB were studied. The expression of HIF-1 α was observed by immunohistochemistry and the morphotogic changes were observed with transmission eletron microscope. Results Stenosis, blockage, dilataltion, capillarization of hepatic sinusoids were the main morphotogic changes of liver. The expression of HIF-1α was positive or stronger positive. There is a positive correlation between the expression of HIF-1α and microcirculation disturbance of liver.Conclusion The disturbance of liver with CHB could exacerbate the dysbolism of nutrient substance and oxygen between hepatic cells and blood circulation. Hypoxia of hepatic cells was an important reason of the liver's pathological changes.
