摘要
目的 探究胃癌患者血浆中hsa_circ_0001588水平,并分析其血浆水平与患者临床特征、Toll样受体4(Toll-like receptors 4,TLR4)、T淋巴细胞亚群的关系.方法 选取2021年3月至2022年5月于我院治疗的胃癌患者124例为研究组,另选取接受胃镜检查确诊为浅表性胃炎的患者130例作为良性组以及健康体检者130例作为对照组.采用实时荧光定量聚合酶链反应、Wmini5146流式细胞仪和双抗体夹心ELISA法检测受试者血浆hsa_circ_0001588水平、TLR4水平和CD3+、CD4+、CD8+、CD4+/CD8+水平.分析血浆hsa_circ_0001588、TLR4、T淋巴细胞对于胃癌的诊断效能以及血浆hsa_circ_0001588水平与TLR4和T淋巴细胞水平的关系.结果 研究组血浆hsa_circ_0001588、TLR4和CD8+表达水平高于良性组和对照组,CD3+、CD4+、CD4+/CD8+水平低于良性组和对照组(P＜0.05),且研究组患者术后hsa_circ_0001588水平下降.临床分期越高、浸润深度越深、分化程度越低,发生远端转移的患者血浆hsa_circ_0001588水平越高(P＜0.05).血浆hsa_circ_0001588、TLR4和T淋巴细胞对于胃癌均有较好的诊断效能,其联合诊断的整体效能最高.血浆hsa_circ_0001588高表达患者CD3+、CD4+和CD4+/CD8+表达较低,TLR4和CD8+表达较高(P＜0.05),其血浆hsa_circ_0001588水平与CD3+、CD4+和CD4+/CD8+表达呈负相关性,与TLR4和CD8+呈正相关性.结论 胃癌患者血浆hsa_circ_0001588水平偏高,且与CD3+、CD4+、CD4+/CD8+水平呈负相关性,与TLR4、CD8+呈正相关性.
Abstract
To explore the level of hsa_circ_0001588 in plasma of patients with gastric cancer and to analyze the relationship between the plasma level of hsa_circ_0001588 and clinical characteristic,toll like receptors 4(TLR4)and T lymphocyte subsets,this study enrolled 124 gastric cancer patients who were treated in our hospital from March 2021 to May 2022 as study group.Simultaneously,another 130 patients diagnosed with superficial gastritis by gastroscopy were selected as benign group,and 130 healthy individuals were set as control group.The plasma hsa_circ_0001588 level was measured by quantitative real-time polymerase chain reaction,the plasma level of TLR4 was detected by double antibody sandwich ELISA,and plasma CD3+,CD4+,CD8+,and CD4+/CD8+levels were tested by Wmini5146 flow cytometry.Then the diagnostic efficacy of plasma hsa_circ_0001588,TLR4 and T lymphocytes for gastric cancer was evaluated,and the correlation between the level of hsa_circ_0001588 in plasma and the level of TLR4 and T lymphocytes in gastric cancer patients was verified.Data showed that the levels of hsa_circ_0001588,TLR4 and CD8+in plasma of study group were higher than those of benign group and control group,while the levels of CD3+,CD4+and CD4+/CD8+were lower than those of benign group and control group(P＜0.05).Furthermore,a decrease was observed in plasma hsa_circ_0001588 level in gastric cancer patients after surgery compared to baseline data.Among gastric cancer patients of different clinicopathological characteristics,patients with high clinical stage,high degree of infiltration,poor differentiation and distant metastasis had high plasma hsa_circ_0001588 level(P＜0.05).Diagnostic analysis denoted that the separate test of plasma hsa_circ_0001588,TLR4 and T-lymphocytes all had good diagnostic efficacy for gastric cancer,while combined test showed the highest diagnostic efficacy.Comparison among gastric cancer patients revealed that high hsa_circ_0001588 expression group had lower expression of CD3+,CD4+and CD4+/CD8+,and higher expression of TLR4 and CD8+than those of low hsa_circ_0001588 expression group(P＜0.05),suggesting that plasma hsa_circ_0001588 level was negatively correlated with CD3+,CD4+and CD4+/CD8+expression,but positively correlated with TLR4 and CD8+.In conclusion,the level of hsa_circ_0001588 in plasma is elevated in patients with gastric cancer,and it has a negative correlation with CD3+,CD4+and CD4+/CD8+,but positive correlation with TLR4 and CD8+expression.
