采用红细胞Ｃ３ｂ受体花环率（ＲＣＲ）、红细胞免疫复合物花环率（ＲＩＣＲ）、肿瘤红细胞花环率（ＴＲＲ），测定了１６例胃癌及１４例大肠癌病人手术前后红细胞免疫功能的动态变化。结果显示，胃癌及大肠癌病人术前１天ＲＣＲ、ＴＲＲ显著低于对照组（Ｐ＜０．００１），而ＲＩＣＲ显著高于对照组（Ｐ＜０．００１）；术后５天各项指标变化不大；术后１４天胃癌及大肠癌病人ＲＣＲ，ＴＲＲ显著高于术前１天（Ｐ＜０．０５），而ＲＩＣＲ显著低于术前１天（Ｐ＜０．０５），但尚未恢复到正常水平。手术切除肿瘤对病人红细胞免疫功能的恢复是有益的，临床医师应注意病人围手术期的处理。
Red blood cell C3b receptor rosette rate (RCR), red cell immune complex rosette rate (RICR), tumor red cell rosette rate (TRR) were used to determine the dynamic changes of red blood cell immune function before and after surgery in 16 patients with gastric cancer and 14 patients with colorectal cancer. The results showed that RCR and TRR in patients with gastric cancer and colorectal cancer were significantly lower than those in the control group (P<0.001), while RICR was significantly higher than that in the control group (P<0.001); The change was not significant; RCR and TRR were significantly higher in gastric cancer and colorectal cancer patients than in postoperative day 1 (P<0.05); RICR was significantly lower than 1 day before surgery (P<0.05), but not yet. Return to normal level. Surgical removal of the tumor is beneficial to the recovery of the patient’s red blood cell immune function, clinicians should pay attention to the patient’s perioperative treatment.
