Peripheral blood T-cell subsets of 54 patients with malignant or benign bone and soft tissue tumors and 20 age-and sex-matched normal controls were studied by using monoclonal antibodies. T-cell subsets were also studied before and after operation in ten patients with osteosarcoma. The number of T cells (OKT 11) and OKT 4 cells significantly decreased in malignant bone and soft tissue tumors. The number of OKT 8 cells increased. Statistically significant decrease in the T4/T8 ratio and the number of macrophage were also found in malignant bone and soft tissue tumors. In giant cell tumor of bone, the number of T cells and OKT 4 cells were also statistically decreased. But, the number of OKT 8 cells and macrophage remained unchanged. The ratio of T 4/T 8 was nearly normal. There was no difference in T cell subsets between benign bone tumors and normal controls. In malignant bone tumors, the number of T cells and T 4/T 8 ratio in some degree may be as a predictor for prognosis.  相似文献

OBJECTIVES: To assess the prognostic value of peripheral blood lymphocyte subsets in patients with bladder cancer who were treated with neoadjuvant chemotherapy. PATIENTS, SUBJECTS AND METHODS: Thirty patients with a histological diagnosis of invasive bladder transitional cell carcinoma and 30 age-matched controls with no evidence of cancer and immunological disorders were evaluated. Peripheral blood samples were assessed in both groups using monoclonal antibodies. Patients with bladder cancer who achieved complete or partial responses and those who had progression of the disease after systemic chemotherapy with methotrexate, vinblastine, epirubicin and cisplatin were compared according to the pretreatment values of the peripheral blood lymphocyte subsets. RESULTS: There were no significant differences in B lymphocyte levels between the groups. In patients with bladder cancer, the percentages of T lymphocytes (P<0.01), natural killer (NK) cells (P<0.05) and the CD4+/CD8+ ratio (P<0.05) were significantly lower than in the control group. In patients who responded to the chemotherapy regimen, the pretreatment values of T lymphocytes (P<0.001), the CD4+/CD8+ ratio (P<0.01) and NK cell levels (P<0.01) were significantly higher than in the patients who did not. CONCLUSION: In patients with invasive bladder carcinoma, cell-mediated immunity may have a role in the resistance to this malignancy and in these patients the pretreatment levels of T lymphocyte subsets may be an indicator of the potential response to chemotherapy.  相似文献

BackgroundThe use of bariatric surgery to treat refractory obesity is increasingly common. The great weight loss that can result from these procedures has been shown to ameliorate certain deleterious effects of obesity. However, the effect of surgery on immune status is unclear. We investigated the relationship between surgical weight loss and peripheral blood lymphocyte percentages in women.MethodsWomen (n = 20, age range 25–59 years, body mass index [BMI] range 36.4–68.2 kg/m2) who had undergone either gastric banding (n = 14) or gastric bypass (n = 6) were enrolled in a prospective study to determine the percentages of their peripheral blood T cells (CD3+, CD4+, and CD8+), CD19+ B cells, and CD3?/CD16+CD56+ natural killer precursor cells before and 85 ± 7 days (3 months) postoperatively using flow cytometry. The data are expressed as the percentage of total lymphocytes ± the standard error of the mean.ResultsA decrease in the BMI at 3 months postoperatively was 12% in the overall study population and 8% and 20% in the banding and bypass groups, respectively. No significant changes were found in the CD4+ or CD8+ T cells (P = .9 and P = .5, respectively), CD19+ B cells (P = .6), or natural killer precursor cells (P = .25) in the overall population or among the patients when stratified by surgical procedure (gastric banding or bypass). The change in CD3+ T cells approached significance (P = .06). A “same direction” (negative) correlation was found between the decrease in BMI and changes in the CD4+ T cell percentages between the pre- and postoperative levels in all the participants, and in the bypass and banding groups separately. However, it only reached statistical significance in the bypass group (r = ?.96, P = .002). When studying the correlation between the decrease in BMI and the changes in CD3+ T cell percentages between the pre- and postoperative levels, a borderline significant negative correlation was found for all participants (r = ?.44, P = .05) and in the bypass group (r = ?.76, P = .08). The rate of change in the CD4+ and CD3+ T cells was greatest among those with the least weight loss and decreased with greater weight loss.ConclusionAn inverse relationship exists between the change in certain T cells (CD4+ and CD3+) and the amount of weight lost after bariatric surgery, mainly gastric bypass surgery. The greater the decrease in BMI, the lower the change in these T cells.  相似文献

初治骨关节结核患者外周血T细胞亚群特点及临床意义   总被引:1,自引:0,他引:1  
目的 探讨初治骨关节结核患者外周血T细胞亚群特点、与临床观测指标的关系及抗结核治疗对患者细胞免疫状况的影响。方法 采用单平台流式细胞术检测骨关节结核患者治疗前和治疗后1-2个月T细胞亚群的绝对数及百分比,并与恶性骨肿瘤患者和健康人比较。结果 初治骨关节结核组CD4及CD8T细胞绝对数较健康对照组低(P〈0.01)。骨关节结核患者在治疗1-2个月后CD4T细胞百分比升高(P〈0.05)。青年组CD8T细胞绝对数和百分比显著高于中年组和老年组(P〈0.05,P〈0.01),CD4/CD8显著低于中年组及老年组(P〈0.01)。T细胞亚群各参数与PPD反应直径、红细胞沉降率和C反应蛋白之间无显著相关性(P〉0.05)。脊柱结核合并脓肿组CD4/CD8较低,CD8T细胞百分比较高(P〈0.01)。结论 初治骨关节结核患者存在细胞免疫缺陷,以中老年组更明显。脊柱结核是否形成脓肿与CD8T细胞有关。初治骨关节结核患者经1~2个月化疗后,细胞免疫状况改善,是病灶清除术的有利时机.  相似文献

Objective: To determine the correlation between the degree of radiculalgia and counts of T lymphocyte subsets in the peripheral blood of patients with lumbar disc herniation. Methods: Forty‐nine patients with lumbar disc herniation (group A) were divided into three subgroups according to Visual Analogue Scale (VAS) pain scores (group A1: n= 12, VAS 0–4.0; A2: n= 24, VAS 4.1–7.0; A3: n= 13, VAS 7.1–10.0. Twenty health blood donors who volunteered to be involved in the study comprised the control group (group B). Peripheral blood counts of various T lymphocyte subsets were measured in each group. Results: (i) The counts of CD4+ T and CD4+/CD8+ lymphocytes were higher in group A than in group B, and the difference between the two groups was statistically significant (P < 0.05). There were also statistically significant differences between group A and group B in the counts of CD3+ and CD8+ T lymphocytes (P < 0.05); (ii) There was no correlation between the VAS scores and the counts of CD3+ T lymphocytes (r= 0.194, P > 0.05). A strong significant correlation was observed between the VAS scores and counts of CD4+ T lymphocytes (r= 0.542, P < 0.05), CD4+/CD8+ (r= 0.468, P < 0.05), which increased with increasing VAS scores in the three subgroups of group A (P < 0.05). However there was a significant negative linear correlation between CD8+ T lymphocyte counts and pain scores (r=?0.462, P < 0.05). Conclusion: Our results suggest that changes in T lymphocyte subsets in peripheral blood take place after prolapse of lumbar intervertebral discs. The current results may provide support for involvement of immunologic mechanisms in low back pain secondary to herniation of the lumbar disc. T lymphocytes may play an important role in the development of symptoms in patients with lumbar intervertebral disc herniation.  相似文献

The effect of lentinan on lymphocyte subsets of peripheral blood, lymph nodes, and tumor tissues in gastric cancer patients was investigated. A 2-mg dose of lentinan was administered to 12 patients intravenously twice, the first at 3–9 days before and the second the day before surgery. The results were then compared with a control group without lentinan administration comprising 12 patients. Regarding peripheral blood and lymph nodes without metastasis, lymphocyte subsets defined with anti-CD3, anti-CD4, anti-CD8, anti-Leu7, and anti-Leu11 were analyzed by flowcytometry. As for tumor tissues, lymphocyte subsets defined with anti-CD3, anti-CD4, anti-CD8, anti-Leu11, and anti-M3 were analyzed after immunohistochemical staining. There were no significant changes in the lymphocyte subsets of peripheral blood between the two groups. In the lymph nodes, the CD4 cell ratios increased; otherwise in regard to tumor-infiltrating lymphocytes (TILs), the number of CD4, Leu11 and LeuM3 cells showed a prominent increase. Therefore, lentinan was observed to produce different effects in accordance with the subjective organs.  相似文献

BackgroundTo date, few studies have evaluated the role of peripheral blood T lymphocyte subsets in patients with clear cell renal cell carcinoma (ccRCC). Here we measured the levels of peripheral blood T lymphocyte subsets and evaluated its prognostic value in ccRCC.MethodsData from 122 patients with RCC from January 2018 to January 2020 were collected. Preoperative peripheral blood T lymphocyte subsets and medical records were analyzed. Kaplan-Meier cures and log rank test were used for analyzing overall survival (OS). Univariate and multivariate survival analyses were underwent by performing the Cox proportional hazards models. Correlations were tested by Pearson’s correlation analysis.ResultsOf 122 patients, a total of 80 ccRCC patients was enrolled. Patients with low CD3+ T cells and low CD4+/CD8+ ratio displayed a worse OS than patients with high CD3+ T cells and high CD4+/CD8+ ratio (P=0.029 and 0.002, respectively). Multivariate analyses showed CD3+ T cells and CD4+/CD8+ ratio were independent predictive factors for the OS (HR: 0.295, 95% CI, 0.091–0.956; P=0.042 and HR: 0.244, 95% CI, 0.065–0.920; P=0.037, respectively). Moreover, NLR negatively correlated with both levels of CD3+ T cells and CD4+/CD8+ ratio (P<0.001, r=−0.398 and P=0.012, r=−0.280, respectively).ConclusionsThe findings of our study suggest that preoperative CD3+ T cells and CD4+/CD8+ ratio in peripheral blood are independent predictors for patients with ccRCC.  相似文献
