【Abstract】Objective To study the expression of serum soluble interleukin-2 receptor (sIL-2R) level in perioperative period of patients with obstructive jaundice and its clinical significance. Methods Serum sIL-2R was measured during perioperative period in 30 patients with obstructive jaundice by using a sandwich enzyme linked immunosorbent assay (ELISA). Results The preoperative serum sIL-2R level in patients with obstructive jaundice was increased obviously. The expression of serum sIL-2R level in them was correlated with the degree and duration of obstructive jaundice and nutritional status respectively (r=0.734, P＜0.01; r=0.646, P＜0.01; r=0.594, P＜0.05). The serum sIL-2R in the patients with malignant obstructive jaundice was significantly higher than that with benign obstructive jaundice (P＜0.05). Among the patients with malignant obstructive jaundice, the serum sIL-2R level in the patients with metastasis was higher than in those without metastasis (P＜0.05). The immunologic function underwent a process from temporary suppression to gradual recovery during perioperative period. On the 21th day after operation the sIL-2R was recovered to normal level in patients with benign obstructive jaundice while it only recovered to preoperative level in patients with malignant obstructive. Conclusion Depressed immunity is observed in patients with obstructive jaundice. The abnormal expression of sIL-2R is related to the type, degree and duration of obstructive jaundice and the nutritional status and metastasis. The result that preoperative sIL-2R might be used to evaluate the state of immunity, clinical condition, and treatment and prognosis of patients with obstructive jaundice.
To investigate the relationship between the serum soluble interleukin-2 receptor (sIL-2R) and the stage and prognosis of breast cancer. Using the method of sandwich ELISA, the preoperative and postoperative sIL-2R in 37 cases of breast cancer was measured, 13 patients with benign disease of breast and 40 normals were also measured. The serum sIL-2R levels in patients with breast cancer were significantly higher than that of the benign disease of breast and the normal controls. The serum sIL-2R about twenty days after operation was significantly lower than that before operation. The sIL-2R in patients with breast cancer was correlative to the clinical stage. The serum sIL-2R in stage Ⅲ patients was remarkly higher than both stage Ⅰ and Ⅱ, its sIL-2R about twenty days after operation remained in a high level. This results showed that expression of the serum sIL2R is correlative to the clinical stage and prognosis of the patients with breast cancer, it can be used as a marker of differentiating the benign from malignant disease of breast.
Interleukin-1 (IL-1), interleukin-2(IL-2) and interleukin-6(IL-6) activities and tumor necrosis factor (TNF) contents in plasma from patients with different sites of cancers as well as controls using bioassay technique were studied. The results showed that the levels of IL-1,IL-2,IL-6 s from patients with different sites of cancer were decreased remarkably in comparision with controls and the contents of TNF from patients with different sites of cancers increased significantly. But the difference between different sites of cancer was not statistically significant. The data suggest that the variations in the contents of TNF and the levels of interleukins may be related to the development of these caner patients.
Effect of radical operation on expression of interleukin-2(IL-2)mRNA and production of IL-2 were markedly reduced preoperatively and four weeks after operation,expression of IL-2 mRNA significantly enhanced,but it was still lower than that in the normal group.Production of IL-2 nearly reached normal level,When PBL was activated by phytohemagglutinin(PHA),expresseion of IL-2 mRNA and production of IL-2 were much higher than that in non-activated PBL.These results suggested that expression of IL-2 were much higher than that in non-activated PBL.These results suggested that expression of IL-2 mRNA and production of IL-2 are dificient in gastric cancer patients,and radical surgery will help them to recover and they can also be improved through activation with PHA.
Soluble interleukin-2 recepter(sIL-2R）levels, NK activity and T lymphocyte subpopulation in peripheral blood were determined in 34 cases of primary liver cancer (PLC). The results showed that the mean level of sIL-2R and CD8 in the patients with primary liver cancer were higher than that in health subjects (Plt;0.01or Plt;0.05), NK activity and T lymphocyte subpopulation (CD3,CD4,CD4/CD8) in the patients with primary liver cancer were much lower than that in health subjects (Plt;0.01), sIL-2R levels in stage II, III patients with primary liver cancer were significantly higher than that in stage I (Plt;0.01). The 6-month mortality rate in 3 groups of patients with sIL-2R level ≥1000u/ml, 500-1000u/ml, andlt;500u/ml were 80.0%, 29.4%and 0 respectively. sIL-2R levels were also decreased (Plt;0.05) in patient with primary liver cancer 4 weeks after immune therapy, but the cell-mediated immunity was increased. It suggests that sIL-2R level determination in peripheral blood is a new biological marker for the assessment of the stage, the response to medical intervention, the prognosis and cell-mediated immunity in primary liver cancer.
目的 通过对白芍总苷治疗前后寻常型银屑病患者血清中白介素（IL）-22水平的研究，探讨其治疗寻常型银屑病的作用机制。 方法 2009年10月－2010年8月采用双抗体夹心酶联免疫吸附法，检测30例寻常型银屑病患者，经白芍总苷治疗前后及健康对照组20例外周血清中IL-22浓度的变化，分析其在治疗前、后与银屑病皮损面积和严重程度指数（PASI）评分的相关性。 结果 寻常型银屑病患者血清IL-22浓度[（90.50 ± 51.80）pg/mL]较对照组[（40.10 ± 17.20）pg/mL]升高，白芍总苷治疗后血清中IL-22水平[（48.70 ± 23.90）pg/mL]较治疗前降低（P＜0.05），并与对照组差异无统计学意义（P＞0.05）；治疗前、后患者血清IL-22水平与PASI评分呈正相关。结论 白芍总苷可能通过调节IL-22发挥治疗寻常型银屑病的作用。

Objective To study the regulative effect of angelica sinensis on cellular immune function in perioperative patients with obstructive jaundice. Methods Fourteen patients with obstructive jaundice were injected with angelica before and after operation for 14 days. The activity of IL-2 and the expression of IL-2R in lymphocytes in peripheral blood were measured, respectively. Results The activity of IL-2 and the expression of IL-2R decreased significantly in patients with obstructive jaundice (P＜0.01). The activity of IL-2 and the expression of IL-2R in peripheral blood lymphocyte increased significantly before and after operations (after treatment using angelica) (P＜0.01), though there was a little decrease after operation but they were still higher than that befor using angelica.Conclusion It maybe useful to use angelica to improve the cellular immune function in patients with obstructive jaundice.
