Abstract：

Objective To investigate the influence and the clinical significance of interleukin-2 (IL-2) on T lymphocyte subgroup after chemotherapy in acute myeloid leukemia patients. Methods Fiftyfour acute myeloid leukemia patients were divided into treatment group (chemotherapy combined with IL-2,28 cases) and control group (pure chemotherapy,26 cases) by radom digits table. In treatment group, IL-2400 000 U was dripped after chemotherapy for 14 days. Then the T lymphocyte subgroup change before and after treatment was examined. Results After 14 days' treatment, the levels of CD3 (0.6026±0.2275 ),CD4(0.4972±0.1224),CD56(0.3016±0.1053 ) in treatment group were significantly higher than those before treatment(0.3926±0.2010,0.2264±0.1190,0.1729±0.1226) and in control group (0.4352±0.1930,0.2738±0.1362,0.1937±0.1268)(P< 0.05). Conclusion IL-2 treatment can obviously raise the levels of T lymphocyte subgroup and can raise the immunologic function.

Abstract：

Objective To investigate the relation between Fas-mediated apoptosis and glucocorticoid treatment in myasthenia gravis (MG). Methods In 17 patients with MG, 6 patients received glucocorticoid treatment (glucocorticoid treatment group),and 11 patients were treated without glucocorticoid (nonglucocorticoid treatment group). Meanwhile, 13 healthy cases were selected as healthy control group. CD4,CD8 and Fas expressions in peripheral blood T lymphocyte were detected by flow cytometry in three groups and analyzed. Results The percentage of CD4-CD8+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group was significantly higher than that in healthy control group[(36.75 ± 11.56)% vs. (26.31 ±9.00)%, P = 0.027], while the percentage of CD4-CD8- cells was significantly lower [(30.56 ± 9.72)% vs.(42.96 ± 11.54)%, P =0.018]. The percentage of CD4-CD8+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group was significantly higher than that in non-glucocorticoid treatment group [(36.75 ± 11.56)% vs. (25.24 ±7.63)% ,P =0.019]. The percentages of Fas+ and CD8 +Fas+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group were significantly higher than those in healthy control group[(46.10 ± 7.13)% vs. (31.22 ± 13.00)%, P=0.006; (62.86 ± 12.29)% vs. (45.59 ±11.50)%, P = 0.003]. The percentage of CD8+ Fas+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group was significantly higher than that in non-glucocorticoid treatment group [(62.86 ± 12.29)%vs (50.84 ± 8.31 )%, P = 0.034]. Conclusions Glucocorticoid treatment may have influence on peripheral blood T lymphocyte subsets in patients with MG. Fas-mediated apoptosis may be involved in the mechanism of glucocorticoid treatment in MG.

Abstract：

Objective To detect the serum level of interleukin (IL)-1 1, lymphocyte subsets and NK cells in patients with idiopathic thrombocytopenic purpura (ITP), and explore the related factors in the pathogenesis of ITP. Methods The serum level of IL-11, lymphocyte subsets and NK cells were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA) and flow cytometry in 50 ITP patients (ITP group) and 30 controls (control group). Results The platelet in ITP group [ (30.21 ± 19.40) ×109/L] was lower than that in control group [ (207.21 ± 31.55 ) × 109/L] obviously (P ＜ 0.05 ); the serum level of IL-11 in ITP group [(255.72 ± 163.43) ng/L] was significantly higher than that in control group [ (40.60 ± 5.57 ) ng/L ] (P ＜ 0.05 ). The correlation analysis indicated that the blood serum levels of IL- 11 had negative relationship with the platelet (r = -0.557 ,P ＜ 0.05). The percentage of CD3+ and CD4+ T lymphocyte percentage, CD4+/CD8+ in ITP group were lower and the percentage of CD8+ T lymphocyte was higher than those in control group obviously (P ＜ 0.05 ). The percentage of CD3- CD(16+56) +NK cell in ITP group was lower than that in control group (P ＜ 0.05). Conclusion IL-11, lymphocyte subgroup and NK cell change correlate with ITP morbidity closely, and the IL-11 level and the platelet possibly have the negative feedback control action.     

高压氧联合化疗对卵巢上皮性癌疗效研究

Objective To discuss the therapentic efficacy of hyperbaric oxygen combined with PC program in newly diagnosed epithelial ovarian cancer patients. Methods Fifty-eight patients with epithelial ovarian cancer were divided into two groups by random digits table: HBO group(30 cases) and PC group(28cases). HBO group were exposed to hyperbaric oxygen of 2 standard atmospheric pressure 60 min, then given chemotherapy 25-30 min after extravehicular: cyclophosphamide 1000 mg/m2 + cisplatin 75 mg/m2.PC group with the same regimen without hyperbaric oxygen therapy were analyzed. The two groups were compared in the efficacy and 3-year survival rate, progression-free survival and adverse reactions. Results The total effective rate, not controlled rate, recurrence rate,recurrence time, 3-year survival rate in HBO group [83.3%(25/30),6.7%(2/30),33.3%(10/30), (21.0 ± 0.8) months,43.3%(13/30)] were better than those in PC group [67.9% (19/28), 17.9% (5/28), 46.4% (13/28), (18.0 ± 0.6) months, 17.9% (5/28)] (P ＜0.05), progression-free survival and overall survival time in HBO group were longer than those in PC group (P ＜0.05) and adverse reactions rate in HBO group was lower than that in PC group (P ＜0.05).Conclusions The hyperbaric oxygen combined with PC programs are better than PC programs in advanced epithelial ovarian cancer chemotherapy response rate, progression-free survival time and 3-year survival rates in ovarian cancer adjuvant chemotherapy. HBO can significantly reduce the PC's hematological toxicity and toxicity of the digestive system.

目的:探讨DC-CIK细胞免疫治疗联合化疗治疗晚期卵巢癌的临床疗效以及对患者血清CD133、DDX4水平的影响。方法:将60例晚期卵巢癌患者随机分为观察组(30例)和对照组(30例),对照组仅接受常规化疗,观察组采用化疗联合DC-CIK细胞免疫治疗。比较两组患者的免疫功能、治疗效果、不良反应以及血清CD133、DDX4水平在治疗前后的变化情况。结果:观察组的客观缓解率(80.0%)高于对照组(50.0%);在治疗后和6个月随访时观察组CD3+、CD3+CD4+、CD4+/CD8+以及NK细胞的比值均高于对照组,CD4+CD25+、CD133、DDX4水平均低于对照组;且治疗前、治疗后、6个月随访后自身比较CD3+CD4+、CD4+/CD8+、NK细胞比值均明显升高,CD133、DDX4水平均明显降低(均P<0.05);治疗后与6个月随访后免疫功能指标两组无差异(P>0.05),骨髓抑制和肝功能损害的发生率观察组低于对照组(P<0.05)。结论:应用DC-CIK细胞免疫治疗联合化疗治疗晚期卵巢癌患者可提高临床治疗效果,增强患者免疫能力,更大幅度降低血清CD133、DDX4水平,减少不良反应的发生,值得临床探索应用。     

妊娠期糖尿病对新生儿免疫功能的影响

目的监测并比较妊娠期糖尿病孕妇在不同血糖控制情况下,其新生儿免疫球蛋白IgG、IgM、IgA与T淋巴细胞亚群CD 3+、CD 4+、CD 8+、CD 4+/CD 8+的值以及自然杀伤(natural killer,NK)细胞的含量值。方法选取凉山彝族自治州第二人民医院210例经确诊为妊娠期糖尿病(gestational diabetes mellitus,GDM)患者分娩的新生儿作为研究组,以及同时期100例由正常孕妇分娩的新生儿作为对照组。根据血糖控制水平,将GDM患者分为血糖控制理想组(GDM-A组)115例患者和血糖控制不理想组(GDM-B组)95例患者。采用流式细胞仪监测外周血T细胞亚群和NK细胞的含量;采用散射比浊度法检测免疫球蛋白的含量。结果经流式细胞仪检测,对于GDM-B组的新生儿,外周血中CD 3+细胞[(52.35±11.17)%]、CD 8+细胞[(15.69±5.58)%]水平均低于对照组和GDM-A组,CD 4+/CD 8+比值[(1.58±0.39)%]高于对照组;而NK细胞(6.37±1.29)%水平明显低于对照组与GDM-A组,差异均有统计学意义(P0.05)。GDM-A组新生儿外周血中NK细胞水平为(8.44±2.05)%,低于对照组(11.19±1.74)%,差异有统计学意义(P0.05)。而其他外周血T淋巴细胞亚群水平与对照组相比,差异无统计学意义(P0.05)。经散射比浊法检测,GDM-B组新生儿外周血IgG水平为(6.45±1.25)g/L,低于对照组[(9.99±1.36)g/L]和GDM-A组[(9.47±1.58)g/L]水平,差异有统计学意义(P0.05)。其他数据3组比较差异无统计学意义(P0.05)。结论 GDM可能会影响新生儿非特异性免疫功能,若妊娠期间血糖控制不理想,则可能造成新生儿免疫功能低下。因此GDM孕妇应积极控制妊娠期间血糖水平。     

胃癌患者围术期免疫状态变化规律研究

目的 探讨胃癌患者围术期外周血T淋巴和免疫球蛋白的水平的变化规律.方法 选取2009年11月～2011年12月于某院进行胃癌手术的78例患者为观察组,同期的78名健康人为对照组,将对照组和观察组术前、术后3d、7d的外周血T淋巴和免疫球蛋白水平进行检测及比较.结果 观察组术前及术后3d、7d的CD3+、CD;、CD4/CD8及IgA、IgM、IgG均先降后升,CD;先升后降,开腹手术患者术后7d与对照组相比差异有统计学意义,P均＜0.05,而腹腔镜手术患者与对照组相比差异无统计学意义,P均＞ 0.05.结论 胃癌患者围术期外周血T淋巴和免疫球蛋白的水平的变化规律对于了解疾病的发展转归有着积极的作用,且对于术式的选择也有一定的指导意义.     

艾滋病肺部感染患者T淋巴细胞亚群及血脂的变化研究

目的 探讨艾滋病(AIDS)肺部感染患者外周血T淋巴细胞亚群及血脂的变化规律.方法 选取2008年3月-2011年12月17例的AIDS肺部感染患者为观察组,同期的17例单纯肺部感染患者为对照组,将两组患者的外周血T淋巴细胞亚群及血脂水平进行检测及比较.结果 观察组的CD3+、CD4+、CD4/CD8比值及HDL-C 水平均分别为(45.36±5.14)％、(5.23±1.21)％、0.18±0.05及(0.68±0.07) mmol/L,CD8+、LDL-C、TG及TC水平分别为(41.56±4.96)％、(2.93±0.53) mmol/L、(2.83±0.23) mmol/L及(3.83±0.16) mmol/L,与对照组比较,差异有统计学意义(P＜0.05).结论 AIDS肺部感染患者外周血T淋巴细胞亚群及血脂呈现紊乱状态,可以作为了解疾病的重要方面,应给予足够重视.
