摘要: 背景与目的: 研究贲门癌、胃癌患者红细胞C3b受体(RBC-C3bR)与CD4+/CD8+比值、NK细胞活性的相关性。 材料与方法: 利用酵母菌花环试验、克隆抗体致敏花环法和MTT法对53例贲门癌、51例胃癌患者及30例正常人外周血RBC-C3bR阳性率、T细胞CD3+、 CD4+百分率、CD4+/CD8+比值及自然杀伤细胞(NK)活性进行测定。 结果: 贲门癌组、胃癌组RBC-C3bR阳性率、CD3+、 CD4+细胞百分率、CD4+/CD8+比值和NK细胞杀伤活性均比正常对照组低,差异具有统计学意义(F=28.68 ,P<0.01),而贲门癌与胃癌组间比较,差异无统计学意义(t=0.081~0.871,P均>0.05);经统计学相关性分析显示,贲门癌、胃癌组RBC-C3bR 阳性率与CD4+/CD8+比值、NK细胞杀伤活性间呈正相关(贲门癌RBC-C3bR阳性率与CD4+/CD8+比值: r=0.431,P<0.01;RBC-C3bR阳性率与NK细胞活性:r=0.347, P<0.05; 胃癌RBC-C3bR阳性率与CD4+/CD8+比值:r=0.429,P<0.01; RBC-C3bR阳性率与NK细胞活性:r=0.528 ,P<0.01)。 结论: 贲门癌、胃癌患者红细胞免疫与白细胞免疫功能均受到抑制。

Abstract: BACKGROUND AND AIM: To investigate the correlation between red blood C3b receptor (RBC-C3bR) and lymphocytic cell (TC) immune function in tumor patients. MATERIALS AND METHODS: RBC-C3bR, natural killer (NK) cell activity and T lymphocyte subsets of 53 patients with gastric cardia carcinoma, 51 gastric cancer and 30 healthy controls were measured by microzyme garland test , MTT-assay and monoclonal anti-human T lymphocyte antibody. RESULTS: Compared with the control group, RBC-C3bR , NK cell activity, CD3+, CD4+,CD4+/CD8+ ratio were significantly decreased in tumor patients (F=28.68 ,P<0.01). Positive correlations were observed between RBC-C3bR with both NK cell activity and CD4+/CD8+ ratio (gastric cardia carcinoma RBC-C3bR and CD4+/CD8+ ratio: r=0.431, P<0.01; RBC-C3bR and NK cell activity:r=0.347,P<0.05; gastric cancer RBC-C3bR and CD4+/CD8+ ratio: r=0.429, P<0.01; RBC-C3bR and NK cell activity,r=0.528, P<0.01). CONCLUSION: The immune funtion of erythrocytes was inhibited same as lymphocytes and there was close relationship between them in gastric cardia carcinoma, gastric cancer patients.
