T 淋巴细胞亚群与炎性因子在评估再生障碍性贫血病情及预后中的应用

摘要

目的：研究T淋巴细胞亚群与炎性因子检测在再生障碍性贫血（A A ）病情及预后评估中的价值。方法选取本院收治的40例AA患者作为AA组，并进一步分为急性再生障碍性贫血（AAA）组和慢性再生障碍性贫血（CAA）组；同时选取同期于本院体检的40例健康者作为对照组。比较两组患者的血常规指标、外周血 T 淋巴细胞亚群百分率和血清炎性因子水平。结果 AA组患者外周血辅助性T淋巴细胞（Th）Th1、Th17细胞百分率及 Th1／Th2、Th17／调节性T淋巴细胞（Treg）比例均高于对照组（P＜0．05），Th2、Treg细胞百分率低于对照组（P＜0．05）；AAA组外周血 Th1、Th17细胞百分率及 Th1／Th2、Th17／Treg比例高于CAA组，Th2、Treg细胞水平低于CAA组（P＜0．05）。AA组患者血清白细胞介素（IL）‐2、IFN‐γ、IL‐17水平高于对照组，IL‐4、IL‐6、IL‐10水平低于对照组，差异均有统计学意义（P＜0．05）；AAA 组血清中IL‐2、干扰素‐γ（IFN‐γ）、IL‐17水平高于CAA组，IL‐4、IL‐6、IL‐10水平低于CAA组，差异均有统计学意义（P＜0．05）；血红蛋白（Hb）水平、PTL与 Th1、Th17细胞水平及IL‐2、IFN‐γ、IL‐17水平呈负相关，与Th2、Treg细胞水平及IL‐4、IL‐6、IL‐10水平呈正相关。结论 AA患者外周血中 T淋巴细胞亚群百分率及血清炎性因子水平存在异常，而且与反映病情严重程度及预后的指标具有良好的相关性。%Objective To study the application value of T lymphocyte subsets and inflammatory factors in evaluating severity andprognosisofaplasticanemia.Methods 40patientswithaplasticanemiainthehospitalwereenrolledinthestudyasAAgroup, which was further divided into acute aplastic anemia(AAA) subgroup and chronic aplastic anemia(CAA) subgroup .In addition to that ,40 healthy people who received physical examination in the hospital during the same period were enrolled in the study as con‐trol group .Then blood routine tests were performed ,T lymphocyte subsets content in peripheral blood and serum inflammatory fac‐tor content were detected and the results were compared .Results Th1 ,Th17 contents and Th1/Th2 ,Th17/Treg ratio in AA group were higher than those in control group(P<0 .05) ,while Th2 ,Treg contents were lower(P<0 .05);Th1 ,Th17 contents and Th1/Th2 ,Th17/Treg ratio in AAA group were higher than those in CAA group(P<0 .05) ,while Th2 ,Treg cells contents were lower . Serum IL‐2 ,IFN‐γ ,IL‐17 contents in AA group were higher than those in control group(P<0 .05) ,while IL‐4 ,IL‐6 ,IL‐10 contents were lower(P<0 .05);serum IL‐2 ,IFN‐γ,IL‐17 contents in AAA group were higher than those of CAA group ,while IL‐4 ,IL‐6 , IL‐10 contents were lower .Hb ,PTL contents were negatively correlated with Th1 ,Th17 contents and serum IL‐2 ,IFN‐γ ,IL‐17 contents ,while positively correlated with Th2 ,Treg cells contents and serum IL‐4 ,IL‐6 ,IL‐10 contents .Conclusion Peripheral blood T lymphocyte subsets and serum inflammatory factors contents in aplastic anemia are abnormal and are correlated with the severity and prognosis related indicators .
