摘    要:目的 通过测定肺结核患者外周血CD4CDhigh25 T细胞的表达,探讨CD4CDhigh25 T细胞的的临床意义。 方法 2008年1月至2010年2月选取住院患者及门诊做体检的健康志愿者共78例,其中肺结核患者40例,门诊健康志愿者38例,应用流式细胞技术测定外周血T细胞表面分子CD4、CD8、CD4CDhigh25,以百分比表示表面分子阳性T细胞占淋巴细胞的比例。 结果外周血CD4CDhigh25 T细胞,肺结核组(1.9%±1.3%)明显高于健康组(0.7%±1.0%),差异有统计学意义(t=5.237, P<0.01)。外周血CD4T细胞,肺结核组(47.9%±11.2%)低于健康组(56.0%±14.6%),差异有统计学意义(t=2.830, P<0.01)。外周血CD8T细胞,肺结核组(26.2%±6.1%)低于健康组(33.0%±11.1%),差异无统计学意义(t=0.353, P>0.05)。肺结核患者治疗2月后,CD4CDhigh25T细胞(1.8%±0.8%)有下降,但与治疗前比较差异无统计学意义(t=0.811,P>0.05)。CD4T细胞、CD8T细胞均有升高(51.6%±14.4%,33.7%±11.5%),但差异无统计学意义(t值分别为=1.496, 0.570,均P>0.05)。 结论 CD4CDhigh25 T细胞参与了肺结核患者的细胞免疫过程,发挥抑制CD4和CD8T细胞的活化与增殖的作用,从而影响了患者的临床演变及预后。

Abstract:Objective To observe the clinical significance of CD4CDhigh25T cells from peripheral blood in pulmonary tuberculosis(PTB) patients.Methods From January 2008 to February 2010,40 hospitalized PTB patients and 38 healthy controls from outpatient department for physical examination were enrolled.CD4,CD8 and CD4CDhigh25T cells which were presented by their percentages in peripheral blood lymphocytes of the above subjects were assessed by flow cytometry.Results The frequencies of CD4CDhigh25T cells in PTB patient...
