首发时间:2017-02-21
摘要:目的:分析非小细胞肺癌患者外周血纯真T细胞及记忆T细胞亚群的变化规律。方法:选取天津中医药大学第一附属医院肿瘤科非小细胞肺癌(NSCLC)患者20例,同期健康志愿者20例,应用流式细胞仪(BD FACS Caliber)检测外周血纯真T细胞(Tn),记忆T细胞亚群(Memory T cell subsets)。所得结果应用SPSS 16.0进行统计分析。结果: NSCLC患者Tn的百分率及绝对值较健康志愿者明显降低(p<0.05),CD8+Tn的百分率及绝对值二者无明显差异(p>0.05);NSCLC患者中枢记忆T细胞(Tcm)、CD8+Tcm的百分率及绝对值较健康志愿者明显降低(p<0.05),NSCLC患者效应记忆T细胞(Tem)、CD8+Tem百分率较健康志愿者明显升高(p<0.05),Tem绝对数二者无明显差异(p>0.05),NSCLC患者CD8+Tem绝对数较健康志愿者明显升高(p<0.05);NSCLC患者终末分化效应T细胞(Temra)的百分率及绝对值与健康志愿者比较无明显差异(p>0.05)。结论:非小细胞肺癌(NSCLC)患者T细胞亚群免疫格局发生变化,患者体内具有分化能力和长期存活特性的Tn及Tcm降低,以发挥免疫效应为主的Tem明显升高。?????

The study of the peripheral blood Na?ve T cell and Memory T cell subsets of non-small cell lung cancer (NSCLC)
Abstract:Objective: To study the peripheral blood Na?ve T cell and Memory T cell subsets of non-small cell lung cancer (NSCLC) patients. Methods: 20 patients with Non small cell lung cancer (NSCLC) that from the Frist teaching hospital of Tianjin University of TCM and 10 healthy controls (HD) were included in this study. Na?ve T cell and Memory T cell subsets were investigated by flow cytometry in peripheral blood from NSCLC patients and healthy controls. The data was analyzed by SPSS 16.0.Result: The frequency and counts of Tn cells was signi?cantly higher in HD-peripheral blood than in NSCLC - peripheral blood (P<0.05), the frequency and counts of CD8+Tn cells was did not differ in HD- peripheral blood and NSCLC - peripheral blood (P>0.05) (Fig. 1B);the frequency and counts of Central memory T cell (Tcm)and CD8+Tcm cells was signi?cantly higher in HD- peripheral blood than in NSCLC - peripheral blood (P<0.05); the frequency of effect memory T cells (Tem)and CD8+Tem cells was signi?cantly lower in HD- peripheral blood than in NSCLC - peripheral blood (P<0.05). The events of Tem cells was did not differ in HD- peripheral blood than in NSCLC - peripheral blood (P<0.05); The events of CD8+Tem cells was signi?cantly lower in HD- peripheral blood than in NSCLC - peripheral blood (P<0.05). The frequency and events of Temra cells was did not differ in HD- peripheral blood than in NSCLC - peripheral blood (P<0.05).Conclusion: The immune pattern of T cell subsets in Non-small cell lung cancer (NSCLC) patients was changed : Tn and Tcm that with differentiation capacity and long term survival characteristics was reduced. Tem that with immune effect was rise.
Keywords: Non-small cell lung cancer (NSCLC) Na?ve T cell Memory T cell subsets
