摘要

目的

观察冠心病(coronary heart disease

CHD)患者不同血糖状态下外周血中1型辅助性T细胞（type 1 T helper cells，Th1）/2型辅助性T细胞（type 2 T helper cells，Th2）的变化，探讨辅助性T细胞在不同血糖状态下的变化对人脐静脉内皮细胞损伤的作用。

方法

纳入本院2019年1月至2021年4月临床确诊的冠心病患者73例及同期进行健康体检的志愿者20例（对照组），冠心病患者根据血糖水平分为糖尿病（diabetes mellitus

DM)组25例、糖耐量异常（impaired glucose tolerance group

IGR）组10例和血糖正常（Normal）组38例，测定循环系统外周血中Th1/Th2细胞亚群的百分比及Th1/Th2相关细胞因子的浓度；分析不同细胞亚群对人脐静脉内皮细胞（human umbilical vein endothelial cells，HUVEC）的杀伤作用。

结果

DM组冠心病患者外周血中Th1细胞百分比及干扰素γ（interferon- γ

IFNγ）的浓度较其余组显著升高[Th1细胞百分比：DM组（10.13±2.34）%，IGR组（6.38±0.89）%，Normal组（6.13±1.19）%，对照组（6.26±1.18）%，

0.05；IFNγ：DM组（58.

29±8.24）pg/mL，IGR组(47.60±3.91)pg/mL，Normal组(47.69±5.08)pg/mL，对照组(39.18±4.34) pg/mL，

0.05

]

，DM组冠心病患者外周血中白介素-10（interleukin-10

IL-10）的浓度较其余组显著降低[DM组: (20.74±3.61)pg/mL，IGR组：(23.83±4.23)pg/mL，Normal组：(30.03±4.28)pg/mL，对照组：(35.69±4.25)pg/mL，

0.05

]

；DM组冠心病患者的外周血单个核细胞（peripheral blood mononuclear cell

PBMC）对HUVEC的杀伤作用较其余组明显增强[DM组: （67.69±1.96）%，IGR组：（78.19±4.02）%，Normal组：（77.78±2.78）%，对照组：（77.64±4.01）%，

]

，而DM组冠心病患者清除CD4

T细胞的PBMC对HUVEC的杀伤作用与其余组差异无统计学意义。

结论

高糖状态下冠心病患者外周血中Th1/Th2细胞百分比及相关细胞因子水平明显失衡，对血管内皮细胞的损伤作用增强。

Abstract

Objective

To observe the changes of type 1 T helper cells (Th1)/type 2 T helper cells (Th2) in peripheral blood of the patients with coronary heart disease (CHD) under different blood glucose conditions

and to investigate the involvement of the changes of Th1/Th2 subsets under different blood glucose conditions on vascular endothelial injury.

Methods

Seventy-three CHD patients diagnosed in our hospital from January 2019 to April 2021 and 20 healthy volunteers (control group) were enrolled in this study. According to the blood glucose level of the CHD patients

they were divided into diabetes group (group DM

=25)

impaired glucose tolerance group (group IGR

=10) and normal blood glucose group (group N

=38). The percentages of Th1/Th2 cell subsets and the concentration of Th1/Th2 related cytokines in the peripheral blood were measured. Cytotoxic activity of different cell subsets against human umbilical vein endothelial cells (HUVECs) were evaluated.

Results

The percentage of Th1 cells and concentration of interferonγ (IFNγ) were significantly higher in the group DM than the groups IGR

N and Control [percentage of Th1 cells; (10.13±2.34) %

(6.38±0.89)%

(

6.13±1.19)% and (6.26±1.18)%

0.05; IFNγ: 58.29±8.24

47.60±3.91

47.69±5.08 and 39.18±4.34 pg/mL

. While the concentration of interleukin-10 (IL-10) in the group DM was obviously lower than that in the other 3 groups (20.74±3.61

23.83±4.23

30.03±4.28 and 35.69±4.25 pg/mL

0.05). Cytotoxic efficiency of peripheral blood mononuclear cells (PBMC) to HUVEC was significantly elevated in the group DM than the other 3 groups [(67.69±1.96)%

(78.19±4.02)%

(77.78±2.78)% and (77.64±4.01)%

0.05

]

. But there was no statistical difference in the elimination of CD4

T cells in the group DM and the other 3 groups.

Conclusion

CHD patients with hyperglycemia present obvious imbalances of Th1/Th2 cells and cytokines in the peripheral blood

which promoting the damage of hyperglycemia to vascular endothelial cells.
