Methods: Sixty cases with chronic hepatic diseases were randomly divided into a Taichong(LR 3) group and a Ququan(LR 8) group, 30 cases in each group, and were respectively treated with electroacupuncture at Taichong(LR 3) and Ququan(LR 8). The blood flow results of the hepatic artery and portal vein by color ultrasonic test were used as the objective indexes, to compare and observe the hemodynamics changes of the hepatic artery and portal vein in the patients before and after EA. Results: After EA, in Taichong(LR 3) group, the average velocity, the lowest velocity, resistance indexes and the highest velocity of blood flow of the hepatic artery, and the highest velocity, average velocity of blood flow of the portal vein, blood flow volume of the portal vein(PVBF), total blood flow volume of the liver(TLBF), and Doppler blood perfusion indexes of the hepatic artery(DPI) were all statistically different from those before intervention(all P<0.05). In Ququan(LR 8) group, the highest velocity,average velocity, lowest velocity and resistance indexes of blood flow of the hepatic artery, and the highest velocity and average velocity of blood flow of the portal vein, and PVBF were significantly different from those before intervention(P<0.05). The TLBF and DPI were significantly different from those before intervention(P<0.01). All various indexes were not statistically different between the two groups. Conclusion: EA at Taichong(LR 3) and Ququan(LR 8) can speed up blood flow velocity of the portal vein, increase PVBF, increase the TLBF, increase the resistance indexes of the hepatic artery, decrease the blood flow velocity of the hepatic artery, and decrease DPI in the liver.展开更多
