Methods: T-lymphocyte subtypes of the peripheral blood and cutaneous delayed-typ e hypersensitivity (DTH) response to two recall antigens, tetanus toxoid (TT) an d purified protein derivative(PPD), were measured in five patients with HIE and 15 healthy controls, respectively. Results: The CD4+ cell cou nts in HIE group were significantly lower than those in control group (P<0. 01). In contrast, CD8+ cells were significantly higher than those in the contro l (P<0.01). The induration sizes of DTH response to two recall antigens wer e smaller in HIE group than those in the control group (P<0.01). Co nclusion: There was an immunologic dysfunction of T lymphocytes in the p atients with HIE.展开更多

文摘探讨俞募配穴针法联合穴位埋针法治疗风痰闭阻型支气管哮喘的疗效及对血清免疫球蛋白E(Immunoglobin E,IgE)、可溶性二聚体细胞因子(Interferon-γ,IFN-γ)、肺表面活性蛋白(Pulmonary surfactant protein,SP-A)水平影响。方法选取医院收治的风痰闭阻型支气管哮喘患者108例,采用区组随机化原则分为两组各54例。对照组给予穴位埋针法,治疗组在对照组基础上给予俞募配穴针法,两组患者数据观察:对比治疗后临床疗效、哮喘控制测试(Asthma control test,ACT)量表评分、第一秒最大呼气容积(Forced expiratory volume in one second,FEV1)、呼气峰值流速(Peak expiratory,PEF)、用力肺活量(Forced vital capacity,FVC)、临床症状评分及IgE、IFN-γ、SP-A水平、临床治疗安全性及患者满意度。结果经过治疗后,治疗组临床疗效显著较高(P<0.05);两组治疗前ACT评分差异无统计学意义(P>0.05);治疗后两组ACT评分明显升高(P<0.05);且治疗组升高较明显(P<0.05);治疗后两组FEV1、PEF、FVC值明显升高(P<0.05);且治疗组升高较明显(P<0.05);两组治疗前临床症状评分差异无统计学意义(P>0.05);两组治疗后咳嗽、呼吸困难、喘息等症状评分显著降低(P<0.05);且治疗组降低较明显(P<0.05);两组治疗前血清IgE、IFN-γ、SP-A水平无差异(P>0.05);两组治疗后血清IgE显著降低,血清IFN-γ、SP-A水平显著升高(P<0.05);且治疗组改善较明显(P<0.05);治疗组未见治疗不良反应,对照组患者出现1例不良反应,症状为恶心,P>0.05;治疗组治疗满意率高达98.15%(53/54),显著高于对照组的83.33%(45/54),P<0.05。结论采用俞募配穴针法联合穴位埋针法治疗风痰闭阻型支气管哮喘具有较好的治疗效果,能够改善血清IgE、IFN-γ及SP-A水平,且本次治疗安全可靠,患者十分认可,值得在临床上推广应用。
