The sonographies of 34 patients with schistosomial hepatic fibrosis accompanied by hepatic carcinoma were analysed retrospectively. The characteristics are listed as follows: 1. The schistosomial change is more obvious in left lobe of liver, while the hepatic carcinoma-tous change is usually seen in the right lobe or both right and left lobes (the latter is more common, 76%) : 2. Most cases (55. 9%) have more than two tumors; 3. There are two sonographic features around tumors: hypoechoic holo or hyperechcic rim; 4. The reticular structure caused by schistosomiasis disappeared partially and was substituted by hypoechoic or hyperecnoic zones, or the original reticular structure changed into irregular structure in disorder; 5. Mass in seen in portal vein or it's branches; 6. With Doppler ultrasound, the pulsatile blood flow signal within the tumor can be detected. The above sonographic features are useful for diagnosis of hepatic carcinoma in patients with chronic schistosomial hepatic fibrosis.

Seventy-four cases of infertility were examined to study the hemodynamics of the bilateral ovarian arteries at 21st day during the corpus luteum phase by color Doppler energy(CDE) and color Doppler flow imaging (CDFI). All the patients were verified by laparoscopy, fallopian tube patency examination and ovarian function test. Twenty-two healthy women served as controls. The results showed that the difference of resistance index（RI）and pulsatility index (PI) of bilateral ovarian arteries between the infertility and the normal controls had statistical significance (P<0.01), and the PI showed negative correlation with the thickness of endometrium (left side: r=0.724, P<0.01; right side: r=0.756, P<0.01). The results also showed that CDE was more sensitive than CDFI in displaying the ovarian arteries. It could be concluded that the elevated resistance of ovarian artery during the corpus luteum phase was one of the important factors that resulted in infertility.
