目的探讨艾迪注射液辅助化疗对中晚期非小细胞肺癌（NSCLC）患者外周血CD4^＋CD25^hiCD127^low高调节性T（Treg）细胞表达的影响。方法60例NSCLC患者随机分为化疗加艾迪注射液组（观察组）和单纯化疗组（对照组）,采用流式细胞术（FCM）和酶联免疫吸附法（ELISA）分别于化疗前后检测外周血中CD4^＋CD25^hiCD127^lowTreg细胞和血清TGF-β1、IL-10水平,同期选取20名健康体检者为健康对照组。结果NSCLC患者外周血中CD4^＋CD25^hiCD127^low Treg细胞占CD;淋巴细胞的比例为（5．77±1．50）％,与健康对照组（3．84±0．96）％相比差异有统计学意义（P=0．000）;血清中IL-10和TGF-β1表达水平[（24．09±6．74）、（197．76±43．76）ng／m1]明显高于健康对照[（19．39±5．73）、（141．13±32．17）ng／ml]（P=0．006,P=0．002）。对照组化疗后CD4^＋CD25^hiCD127^low Treg细胞水平显著降低（P=0．048）,细胞因子IL-10、TGF-β1的表达水平[（22．25±6．79）、（184．85±49．11）ng／ml]与化疗前[（24．37±8．10）、（197．16±44．57）ng／ml]相比差异无统计学意义（P=0．276,P=0．314）。观察组化疗后CD4^＋CD25^hiCD127^low Treg细胞和细胞因子IL-10、TGF—β1表达水平[（4．36±1．19）％,（20．16±4．73）、（165．42±39．57）ng／ml]与化疗前[（5．78±1．50）ng／ml,（23．81±5．15）、（198．35±43．68）ng／m1]相比降低,差异有统计学意义（P=0．000,P：0．006,P=0．003）。结论中晚期NSCLC患者外周血中Treg细胞表达水平增高,艾迪注射液配合化疗可以降低NSCLC患者的Treg细胞水平,改善机体免疫状态。 相似文献

Objective To evaluate the clinical diagnostic application and operative efficacy of the expression of NKG2D in peripheral blood CD+8 NKT cell and its ligand sMICA in patients with esophageal or cardiac carcinoma.Methods The peripheral blood NKG2D positive CD+8 NKT cell percentage was concomitantly determined by flow cytometry in 53 preoperative patients including 29 postoperative patients with esophageal or cardiac carcinoma and 30 healthy controls.The serum sMICA was determined by ELISA.Results The peripheral blood NKG2D positive CD+8 NKT cell percentage in patients was significantly lower than that in controls [(77.632±8.972) % vs (89.053±6.515) %] (t = -6.113,P ＜0.05); with stage Ⅱ,Ⅲ,Ⅳ,it decreased significantly in order (F = 99.251,P ＜0.01);with lymph node metastasis lower than that without lymph node metastasis (t = -10.384,P ＜0.01); squamous carcinoma was higher than adenocarcinoma (t =9.899,P ＜0.01); postoperative was significantly higher than preoperative (t =-4.319,P ＜0.01).The level of serum sMICA in patients was significantly higher than that in controls [(326.28±85.407) pg/ml vs (210.00±92.560) pg/ml](t =7.292,P ＜0.01); with stage Ⅱ,Ⅲ,Ⅳ,it increased significautly in order (F =63.355,P ＜0.01); with lymph node metastasis higher than that without lymph node metastasis (t =7.770,P ＜0.01); squamous carcinoma was lower than adenocarcinoma (t =-7.593,P＜0.01); postoperative was significantly lower than preoperative (t =7.027,P ＜0.01).Serum sMICA could inhibit peripheral blood CD+8 NKT cell activation receptor NKG2D (F =142.773,P ＜0.05),determination coefficient R2 = 0.7368.Conclusion The level of peripheral blood CD+8NKT cell activation receptor NKG2D and serum sMICA in patients could be an assistant indicator for 相似文献
