Ultrasonic diagnosis of patients with clonorchiasis and preliminary study of pathogenic mechanism

Abstract Objective To discuss the liver function damage mechanism of patients with clonorchiasis by analyzing the ultrasound characteristics, liver function, change of the serum inflammatory factors and cell apoptosis factors. Methods Color Doppler ultrasound technique was adopted to detect the portal vein and blood flow change of patients with clonorchiasis; ELISA was used to determine the level of different serum inflammatory factors. The levels of serum total bilirubin, serum albumin and glutamic-pyruvic transaminase were detected by automatic biochemical analyzer. Western blot was used to determine the expression of proteins relevant to apoptosis. Results Compared with the health control group, the trunk diameter of portal vein and the thickness of spleen, as well as the hepatic artery pulsation index of clonorchiasis patients increased obviously, the mean blood flow velocity of portal vein ( P P P P P P P P P Conclusions Changes of ultrasonic characteristics and liver dysfunction, caused by liver fluke infection, may be related to that both inflammatory response and apoptosis response have participated in the pathogenic process and liver damage course of clonorchiasis.
