复发性流产患者主动免疫治疗后淋巴细胞免疫表型的变化

目的探讨原因不明复发性流产(URSA)患者行淋巴细胞主动免疫治疗(LIT)后淋巴细胞免疫表型的变化对治疗效果的评估价值。方法采用流式细胞术分析URSA患者LIT前后外周血T淋巴细胞、B淋巴细胞、NK细胞和调节性T细胞免疫表型的变化(P0.05)。结果 25例URSA患者经LIT后成功妊娠16例,治疗后所有URSA患者(n=25)和妊娠成功组(n=16)外周血CD3+T细胞、CD4+HLA-DR+T细胞比例较治疗前均明显增加,CD4+T和CD3-CD56+NK细胞比例明显降低(P0.05);而治疗前后B细胞和Treg细胞、CD56bright CD16-NK、CD56dimCD16+NK、CD3+CD56+NKT及CD69+NK细胞比例则无明显变化(P0.05)。结论 LIT后外周血T细胞、NK细胞的比例发生了明显变化,CD4+T细胞、CD3-CD56+NK细胞比例降低和CD3+T细胞、活化CD4+T细胞增加也许有利于维持妊娠,T细胞和NK细胞的免疫表型有望作为LIT疗效评估的一个重要指标。     

结肠癌术后化疗对外周血免疫细胞比例及凋亡的影响

目的研究结肠癌术后化疗患者外周血免疫细胞亚群变化特点、淋巴细胞凋亡状况及其意义。方法应用流式细胞术对40例结肠癌患者手术前后(术前1d、术后3d、化疗前1d)、化疗过程(化疗第3d、化疗后3d)中外周血T淋巴细胞亚群及NK细胞水平进行检测,以AnnexinV/PI双标流式细胞术对淋巴细胞凋亡、坏死状况进行检测。结果结肠癌根治术后3d,患者外周血T淋巴细胞及NK细胞数量较术前有所减少,但无显著差异(P>0.05)。至化疗前1d,患者外周血CD3 ,CD4 T细胞及NK细胞数量较术前显著增高(P<0.01),但CD8 T细胞数量减少(P<0.05)。化疗3d后,患者外周血CD3 ,CD4 ,CD8 T细胞及NK细胞水平较术前全面下降(P<0.05),但CD4 /CD8 比例变化不大,而淋巴细胞凋亡坏死比例明显升高。至化疗结束后3天,T淋巴细胞各亚群及NK细胞数量开始逐渐回升。结论结肠癌根治术手术本身对患者外周血淋巴细胞及NK细胞影响不大,术后患者免疫细胞水平明显升高,机体免疫状况明显改善。化疗可造成患者机体的一过性免疫抑制,可能与其造成机体淋巴细胞的凋亡坏死有关。

Effect of Xuebijing injection on peripheral T-lymphocyte subpopulations in patients with severe trauma

Objective： To investigate the effect and clinical significance of Xuebijing injection on peripheral T-lymphocyte subpopulations in patients with severe trauma. Methods： Thirty-three patients with severe trauma were randomly divided into a control group （n=16） and a treatment group （n=17）. The patients of two groups were all treated conventionally, and the only difference was that Xuebijing injection was given to patients of the treatment group. The CD4^＋ and CD8^＋ subpopulations of T-lymphocyte in the peripheral blood were detected respectively on admission, 3rd and 5th days after trauma by double antibody labeling and flow cytometry. Results： The CD4^＋ T-lymphocytes and CD4^＋/CD8^＋ ratio of peripheral blood in patients with severe trauma decreased markedly on the 3rd and 5th days after trauma. Furthermore, compared with control group, the peripheral CD4^＋ T-lymphocytes and CD4^＋/CD8^＋ ratio of treatment group renewed obviously on the 5th day after trauma, and showed statistical differences （P〈0.05）. Conelusion： In the treatment of patients with severe trauma, the early use of Xuebijing injection is effective in correcting disorder or suppression of T-lymphocyte subpopulations regulating network, and promoting a more balanced profile of immunologic function.

Lymphocyte subsets in renal allograft recipients with chronic hepatitis C virus infection.

BACKGROUND: The pathogenetic mechanisms of chronic hepatitis C virus (HCV) infection in renal allograft recipients are not well established. This study aimed to examine the relationship between altered immune status and HCV-related liver disease, by determining the changes in peripheral blood lymphocyte and natural killer (NK) cell subsets in these subjects. METHODS: Peripheral blood lymphocyte, NK cell and activation markers were detected by flow cytometry in renal allograft recipients with (TpC+) or without (TpC-) HCV infection, and compared with age- and sex-matched patients with post-transfusional chronic HCV infection (TfC+) and healthy controls. RESULTS: CD19+ cells were reduced in renal allograft recipients compared with controls. TpC+ subjects had increased CD3+CD8+ cells compared with controls, and increased CD3+DR+ cells but reduced CD4+ CD38+ and CD3-CD16/56+ cells compared with controls as well as TfC+ patients. TfC+ patients and controls had similar numbers and proportions for the lymphocyte subsets and NK cells. Chronic liver disease in HCV-infected renal allograft recipients was associated with increased CD3+CD16/56+ cells but reduced CD4+CD38+ cells. Reduction of CD3-CD16/56+ cells was noted in TpC+ subjects without liver disease. Yet among post-transfusional (TfC+) subjects this was associated with chronic hepatitis. CONCLUSIONS: Peripheral blood suppressor/cytotoxic T lymphocytes are increased, whereas activated helper/inducer T lymphocytes and NK cells are reduced, in renal allograft recipients with HCV infection. Increased non-MHC-restricted cytotoxic T cells and reduced NK cells are associated with the presence or absence of liver disease respectively. These data suggest that immune mechanisms are important in the pathogenesis of chronic hepatitis C after renal transplantation.     

Systemic immune dysfunction in pancreatic cancer patients

Background and aims We investigated the immune status in 32 pancreatic cancer patients (PC) in comparison with healthy controls (HC). Materials and methods Using flow cytometry, peripheral blood lymphocytes (PBL) were characterized by the expression of surface markers for T helper cells (CD4), T suppressor cells (CD8), B cells (CD19) and NK cells (CD56). The blastogenic response of PBL was analyzed after stimulation with concavalin A (ConA), phytohemagglutinin (PHA), pokeweed mitogen (PWM) and anti-CD3 antibodies. The serum levels of TNF-α, IL-1β, IL-2, IL-10, IL-12, IL-18, IL-1RA, sIL-2R and TGF-β were determined by ELISA. Results No differences in the distribution of peripheral immunocytes in PC were found, whereas the blastogenic response of peripheral blood lymphocytes (PBL) after stimulation with PHA or anti-CD3 antibodies was significantly decreased in PC. In PC, we found reduced serum levels of IL-2 and significantly elevated levels of TNF-α, TGF-β1, IL-10, IL-2R, IL-1β and IL-1RA. Conclusion These data provide evidence for a systemic immune dysfunction in pancreatic cancer patients characterized by a shift towards a T helper cell type 2 cytokine profile, a significant elevation of substances related to T cell suppression and a reduced blastogenic response to PHA and anti-CD3 antibodies of PBL.

The characterization of peritoneal and pleural exudate cells from malignant effusions

The immune function of peripheral blood cells and cells from the pleural and abdominal effusions of patients with advanced cancer was compared to that of peripheral blood cells from controls. The parameters examined included lymphocyte subsets, natural killer (NK) cell activity, and anti-Daudi and lymphokine-activated killer (LAK) cell activity. The percentage of CD4⁺ pleural and peritoneal exudate cells (PEC) was significantly higher than the percentage of peripheral blood mononuclear cells (PBMC) in the patients. The percentage of CD8⁺CD11⁺ PEC and PBMC, being the suppressor T-cells, of the patients was increased compared with controls, while the percentage of CD8⁺CD11^– PEC, being the cytotoxic T-cells, was identical to the PBMC of both patients and controls. The NK activity of PEC was significantly lower than that of PBMC in both patients and controls, and there was no correlation between the NK activity of PBMC and PEC. Although the anti-Daudi activity of PEC was markedly low, LAK cells with high activity could be induced by culture with interleukin-2 for 4 days. These results suggest that the immune function of cells in malignant effusions may be depressed due to a low population of cytotoxic T cells, low NK activity and increased suppressor T cells, while the local administration of interleukin-2 may induce LAK cells. Therefore, effective local immunotherapy for malignant effusions should not only augment effector cells, but also inhibit supprssor cells.     

肝癌患者外周血CD4~+CD25~+调节性T细胞的变化及其意义

T lymphocyte subsets and antilymphocyte antibodies in lupus nephritis

T lymphocyte subsets were determined in 12 patients with untreated systemic lupus erythematosus (SLE) and in 14 healthy controls. Six out of 8 (75%) patients with lupus nephritis had reduction in the percentage of T helper cells and low helper: suppressor cell ratios compared with controls. None of the 4 patients without nephritis had low ratios. Cold-reactive anti-lymphocyte antibodies cytotoxic to both the helper and the suppressor cells were detected in 7 of the 8 patients who had nephritis. Low T helper: suppressor cell ratio in SLE seems to correlate with the presence of active nephritis.     

A clinical study of immunological status in patients with gastric cancer: with special reference to T-cell subsets, interleukin-2 in the lymphocytes of peripheral blood

Peripheral blood lymphocytes of 63 patients with gastric cancer were studied by using different monoclonal antibodies and flow cytometry. Used monoclonal antibodies were OKT3 (total T cell), OKT4 (helper/inducer), OKT8 (suppressor/cytotoxic), Leu 7 and Leu 11 (NK/K cell). Interleukin-2 was measured by tritium-labelled thymidine CTLL assay on the supernatant of peripheral blood lymphocytes after 24 hours stimulation with phytohemagglutinin. Interleukin-2 receptor was also studied by using monoclonal antibody (for Tac antigen) and flow cytometry. The results were as follows: among peripheral blood lymphocytes; 1. the number of OKT3, OKT4 cells and the percentage of OKT4 cells decreased significantly with more advanced stage of cancer. 2. production of interleukin-2 also decreased with the progression of the cancer. 3. decreases in the OKT4/OKT8 ratio were found with cancer progression. 4. the percentage and the number of OKT8 cells increased. 5. the percentage and the number of Leu 11 cells and the number of Leu 7 cells were increased significantly in the stage III (moderately advanced cancer). These results suggested that the activated helper T cells decreased, the induction capability of cytotoxic T cells decreased and the suppressor T cells increased with the progression of cancer. Quantitative and qualitative change in T-cell subsets in advanced stage may be one factor responsible for immunosuppression.
