目的探究肺结核(pulmonary tuberculosis,PTB)患者血清CXC趋化因子配体8(C-X-C motif chemokine ligand 8,CXCL8)、调节活化正常T细胞表达和分泌因子(regulate upon activation normal T cell expressed and secreted,RANTES)水平与治...目的探究肺结核(pulmonary tuberculosis,PTB)患者血清CXC趋化因子配体8(C-X-C motif chemokine ligand 8,CXCL8)、调节活化正常T细胞表达和分泌因子(regulate upon activation normal T cell expressed and secreted,RANTES)水平与治疗效果的关系。方法选取2020年2月至2021年2月温州医科大学附属衢州医院收治的450例初诊涂阳的PTB患者为研究对象。所有患者均采用标准抗PTB治疗,根据治疗效果分为有效组(n=383)和无效组(n=67)。比较两组一般资料及血清CXCL8、RANTES水平,采用Logistic回归分析PTB患者治疗效果的影响因素以及CXCL8、RANTES对PTB患者治疗效果的预测价值。结果治疗后,450例PTB患者治疗有效率为85.11%。无效组的全程督导占比低于有效组,吸烟、外地户籍占比及治疗前血清CXCL8、RANTES水平高于有效组,差异均有统计学意义(P<0.05),性别、职业、年龄比较,差异无统计学意义(P>0.05)。多因素Logistic回归分析结果显示,吸烟、户籍类型、CXCL8及管理方式是PTB患者治疗无效的影响因素(P<0.05)。血清CXCL8、RANTES预测PTB患者治疗效果的曲线下面积(areas under the curve,AUC)分别为0.877、0.865,敏感度分别为77.6%、79.1%,特异性分别为88.3%、89.3%;CXCL8、RANTES联合预测PTB患者治疗效果的AUC为0.955,敏感度为94.0%,特异性为85.4%。结论血清CXCL8、RANTES高水平与PTB患者治疗不良密切相关,检测血清CXCL8、RANTES有利于评估PTB患者治疗效果,且二者联合预测效果更佳。展开更多
This study examined the role of regulated upon activation normal T cell expressed and secreted(RANTES) and its receptor C-C chemokine receptor type 5(CCR5) in gastric cancer metastasis and the associated mechanism...This study examined the role of regulated upon activation normal T cell expressed and secreted(RANTES) and its receptor C-C chemokine receptor type 5(CCR5) in gastric cancer metastasis and the associated mechanism.The expression of RANTES and CCR5 was detected by using immunohistochemical staining and Western blotting in the gastric cancer tissues obtained from 60 gastric cancer patients with or without lymph node metastasis(n=30 in each).The results showed that the expression levels of RANTES and CCR5 were higher in gastric cancer with lymph node metastasis than in that without metastasis(P0.05).The expression levels of RANTES in 30 lymph nodes with cancerous invasion were higher than in 30 normal lymph nodes(P0.05).Chemotactic test revealed that the number of migrating gastric cancer cells(n=295.0±54.6) induced by the protein of cancer-invading lymph nodes was greater than that by the protein mixture from cancer-invading lymph nodes and RANTES antibody(n=42.5±11.6)(P0.05).RT-PCR showed that the expression levels of the main Th1 cytokines(IL-2,γ-IFN) were lower in gastric cancer with lymph node metastasis(2.22±0.90,3.26±1.15 respectively) than in that without metastasis(3.07±1.67,4.77±1.52 respectively)(P0.05),but the expression level of the main Th 2 cytokine(IL-10) was higher in gastric cancer with lymph nodes metastasis(6.06±2.04) than in that without metastasis(4.88±1.87)(P0.05).It was concluded that RANTES and its receptor CCR5 may contribute to gastric cancer metastasis through influencing the balance of Th1/Th2.RANTES and CCR5 may become a marker of gastric cancer metastasis.展开更多
