| 目的：研究Treg细胞在发热CTD 患者外周血表达对结核感染的诊断价值。方法：对103 例发热CTD患者进行T-SPOT.TB
试验，将39 例阳性者设为实验组-1，进行抗结核治疗，将64 例阳性者设为实验组-2，另选取40 例健康者作为对照组，检测三组
外周血CD4+CD25+Treg 细胞、Foxp3 基因、IL-10、TGF-茁的表达。结果：实验组CD4+CD25+Foxp3 Treg细胞占CD4+T 比例高于对照
组（P＜ 0.05），实验组-1 治疗前外周血CD4+CD25+Foxp3 Treg细胞占CD4+T 比例高于实验组-1 治疗后、实验组-2（P＜0.05）；实
验组TGF-茁表达量低于对照组（P＜ 0.05），实验组-1 治疗前低于实验组-1 治疗后及实验组-2（P＜0.05）；实验组-1 治疗前IL-10
表达量低于实验组-1 治疗后、实验组-2及对照组（P＜ 0.05）。结论：CD4+CD25+Foxp3 Treg 细胞在发热CTD 伴有结核感染患者外
周血中的表达升高，其变化可作为结核感染诊断的辅助性指标。 |

| Objective:To investigate the diagnosis value of expression of Treg cells in the peripheral blood of CTD patients with
fever on TB infection, so as to improve the accuracy of early diagnosis of TB infection.Methods:103 patients with fever CTD underwent
T-SPOT.TB test. The 39 patients with T-SPOT.TB test positive were set as group-1, and got anti-TB treatment. The 64 patients with
T-SPOT.TB test negative were set as group-2. The other 40 healthy volunteers were set as the control group. Detect the expression of peripheral
blood CD4+CD25+ Treg cells, fork head/winged helix transcription factor (Foxp3) gene expression and interleukin -10 (IL-10),
transforming growth factor -β(TGF-β) of the three groups.Results:The ratio of peripheral blood CD4+CD25+ Foxp3 Treg cells among
CD4+T lymphocyte was significantly higher in the experimental group than in the control group(P<0.05). In experimental group-1, the ratio
of the peripheral CD4+CD25+ Foxp3 Treg cells among CD4+T lymphoid cells before treatment was significantly higher than after treatment,
as well higher than that of the experimental group-2 (P<0.05). The expression of TGF-βin experimental group were lower than in
the control group (P<0.05), and that of the experimental group-1 before treatment were lower than that of the experimental group-1 after
treatment and experimental group-2 (P<0.05). The IL 10 level of the experimental group-1 before treatment was lower than that of the experimental
group-1 after treatment, the experimental group-2 and the control group (P<0.05).Conclusion:The expression of CD4+CD25+
Foxp3 Treg cells were elevated in peripheral blood of fever CTD patients accompanied with TB infection. Such change could be used as
supplementary indicators in TB infection diagnosis. |
