摘 要:目的分析全身炎症反应综合征(SIRS)及脓毒症(SEPSIS)患者在连续性血液净化(CBP)治疗前后转化生长因子β(TGF-β)及T淋巴细胞亚群的变化,探讨CBP治疗对患者免疫系统的影响。方法 38例行CBP治疗的患者,均符合SIRS诊断标准,其中16例患者有明确感染证据(SEPSIS组),22例无感染证据(SIRS组)。均行CBP治疗(单次治疗时间>20小时),分别于治疗0、5、10、15、20小时留取乙二胺四乙酸(EDTA)抗凝血标本,用酶联免疫吸附I测定(ELISA)方法测定血清中TGF-β的浓度,用流式细胞分析法测定CD3+T淋巴细胞,以及CD4+、CD8+、CD4+CD25+T细胞亚群,并观察治疗过程中TGF-β及T淋巴细胞及其亚群变化。同时于治疗0、10、20小时对患者行急性生理学与慢性健康状况评分Ⅱ(APACHEⅡ)评分。结果①TGF-β于治疗0、5、10、15、20小时的值分别为SIRS组:(70±20)ng/L、(130±17)ng/L、(100±18)ng/L、(115±20)ng/L、(110±22)ng/L,SEPSIS组:(75±32)ng/L、(100±19)ng/L、(70±27)ng/L、(74±28)ng/L、(75±28)ng/L,两组均表现为CBP治疗早期(5小时)一过性快速升高(P<0.05),尔后下降,维持在一定水平,SEPSIS组较SIRS组为低(P<0.05)。②CBP治疗0、5、10、15、20小时SIRS组CD3+淋巴细胞为:(42±12)%、(58±11)%、(64±13)%、(62±13)%、(55±10)%;CD4+T细胞为:(20±8)%、(28±6)%、(32±10)%、(34±8)%、(36±8)%;SEPSIS组CD3+淋巴细胞为:(68±9)%、(71±10)%、(72±11)%、(77±12)%、(85±4)%、CD4+T细胞为:(35±11)%、(43±8)%、(44±9)%、(46±13)%、(48±8)%,CD3+淋巴细胞与CD4+T细胞亚群于两组均表现为逐渐升高趋势(SIRS组CD3+,但SIRS组升高速度更快,在治疗后5小时即出现明显升高(P<0.01),10、15、20小时一直保持升高的状态(P<0.01)。而SEPSIS组CD3+T淋巴细胞及CD4+T细胞亚群升高的状态直至治疗后20小时才明显出现(P<0.05)。③T淋巴细胞CD4+CD25+亚群在两组均表现逐渐升高(SIRS组0、20小时CD4+CD25+T细胞为:(28±7)%、(39±11)%,SEPSIS组0、20小时CD4+CD25+T�Objective To evaluate changes of transforming growth factor beta (TGF-β) and T lymphocyte subsets in patients of systemic inflammatory response syndrome(SIRS) and SEPSIS before and after continuous blood purification (CBP) therapy with high volume continuous veno venous hemofiltration (HV-CVVHF) and/or high volume continuous veno-venous hemodiafihration(HV-CVVHDF) and to explore effects of CBP therapies on immune systems. Methods All 38 patients, including 16 cases with clear infection evidence (SEPSIS group) while 22 cases without infection evidence (SIRS group), were accordant to the diagnostic standard. Both groups received HV-CVVH or HV-CVVHDF therapy (the time of single treatment was more than 20 h). The serum adding EDTA as anticoagulant was taken in 0 h, 5 h, 10 h, 15 h and 20 h during the treatment, respectively. CD3+ T lymphocytes, and CD4+ ,CD8+ ,CD4+ CD25+ T lymphocyte subsets were checked by flow cytometry(FCM) and TGF-β in the serum were analyzed by ELISA. Meanwhile, the APACHE II was used to score patients in 0 h, 10 h and 20 h during the treatment. Results (1)The serum level of TGF-β in SEPSIS group at 0,5,10,15 and 20 h during the treatment was (70± 20) ng/L,(130±17) ng/L,(100±18) ng/L,(115±20) ng/L,and (110±22) ng/L,while in SEPSIS group,it was (75± 32) ng/L, (100±19) ng/L,(70±27) ng/L,(74±28) ng/L,(75±28) ng/L. During the early stage of CBP therapy (within 5 hours), the serum contents of TGF-β in two groups were elevated temporarily and then decreased and maintained in relatively stable state. After CBP treatment, the serum content of TGF-β in SEPSIS group was significantly lower than that in SIRS group( P 〈0.05). (2)The percent of CD3+ leukomonocyte at 0,5,10,15 and 20 h after CBP therapy it was (42± 12) %, ( 58± 11 ) %, (64±13) %, (62± 13) %, (55± 10) % in SIRS group; while in SEPSIS group,it was (68±9)% ,(71±10)% ,(72±11)% ,(77±12
