本文报道28例肝癌腹水(其中15例有门脉血栓)、37例肝硬化腹水。25例肝硬化无腹水病人,血浆、腹水中心钠素(ANP)、肾素(RA)、血管紧张素Ⅱ(AT—Ⅱ)、醛固酮(ALD)的浓度测定。腹水组比无腹水组的血浓度降低(P<0.05～0.01);肝癌腹水组比肝硬化腹水组血浆中浓度降低,腹水中浓度升高,P均<0.05～0.01;有门脉血栓肝癌组比无门脉血栓肝癌组血浆中浓度降低,腹水中浓度升高,P均<0.05～0.01。 This article reports 28 cases of liver cancer ascites (15 cases of portal vein thrombosis), 37 cases of cirrhosis and ascites. Twenty-five patients with cirrhosis without ascites were tested for plasma, ascites ANP, AT, AT and ALD levels. The ascites group had lower blood concentration than the group without ascites (P <0.05-0.01). The ascites in liver cancer group had a lower plasma concentration than ascites group and a higher ascites concentration (P <0.05-0.01) Compared with portal vein thrombosis, the plasma concentration of HCC decreased and the concentration in ascites increased (P <0.05-0.01).
