简介：摘要目的探讨2型固有淋巴细胞(ILC2)与结核分枝杆菌(Mycobacterium tuberculosis，Mtb)不同感染者外周血中Treg/Th17比值的相关性研究。方法选取初治肺结核患者(ATB组)30例和复治肺结核患者(RTB组)26例，潜伏Mtb感染者(LTBI组)22例，结核菌素皮肤试验阴性者(TST－组)17例。采用流式细胞术检测各组外周血中ILC2占CD45＋细胞比例、Th17和Treg细胞分别占CD4＋T淋巴细胞比例，实时荧光定量PCR法检测Foxp3 mRNA、RORγt mRNA，Pearson法进行ATB组和RTB组患者外周血中Th17与Treg相关性、ILC2与Treg/Th17比值相关性分析。结果RTB组和ATB组ILC2比例明显高于LTBI组和TST－组，且RTB组中的ILC2比例明显高于ATB组(P<0.05)。RTB组中的Th17比例低于ATB组(P<0.05)，且两组均低于LTBI组和TST－组。RTB组中的Treg比例低于ATB组(P<0.05)，且接近于LTBI组和TST－组，但ATB组和RTB组中的Treg/Th17比值均高于LTBI组和TST－组，两组间差异无统计学意义(P>0.05)，Foxp3 mRNA、RORγt mRNA和Foxp3/RORγt比随之发生一样的变化。同时，发现在ATB组和RTB组中Th17与Treg均无相关性(r＝0.023, P＝0.444; r＝0.428, P＝0.150)。ATB组ILC2与Treg/Th17比值之间成正相关(r＝0.794, P＝0.000)，RTB组ILC2与Treg/Th17比值之间未发现有相关性(r＝0.197, P＝0.297)。结论本研究肺结核患者外周血中ILC2增高，且RTB组高于ATB组；RTB组中Th17在外周血中所占比例低，并参与炎症反应，而RTB组中的Treg未参与炎症反应，但在ATB组中可能有一定的抑制作用，进一步研究发现Th17参与的炎症反应未受到Treg的调控。ILC2参与ATB患者Treg/Th17失衡，而在RTB患者中未发现此现象。

简介：摘要目的探究给予慢性阻塞性肺疾病（COPD）稳定期患者金水宝胶囊辅助治疗，对其辅助性T细胞17（Th17细胞）、Th17细胞/调节性T细胞（Treg细胞）的影响。方法选取2017年4月至2019年8月接受治疗的72例COPD稳定期患者，行随机数表法分为对照组（36例，常规治疗）和观察组（36例，常规治疗+金水宝胶囊辅助治疗），比较两组患者临床疗效、Th17细胞、Th17细胞/Treg细胞水平及不良反应。结果观察组患者治疗总有效率为88.89%（32/36），高于对照组的69.44%（25/36），差异有统计学意义（χ2 =4.126，P=0.042）；治疗后，观察组Th17细胞值高于对照组[（1.52±0.52）%比（1.25±0.47）%]，Th17细胞/Treg细胞值高于对照组[（0.58±0.13）比（0.49±0.15）]，差异均有统计学意义（t=2.311、2.721，P=0.024、0.008）；观察组不良反应发生率为2.78%（1/36），对照组不良反应发生率为8.33%（3/36），组间比较差异无统计学意义（χ2 =0.265，P=0.304）。结论金水宝胶囊辅助治疗可提升COPD稳定期临床疗效，提高Th17细胞、Th17细胞/Treg细胞值，同时控制不良反应发生。
