ABSTRACT
Objective To study the influence of serum containing Fuzheng Toudu Qudu Recipe, a Chinese formula with the actions of supporting healthy qi to expel and remove toxicity, on serum levels of interleukin 2 (IL-2) and soluble interleukin 2 receptor (sIL-2R) at different stages of CD34+derived dendritic cells (DC) of patients with minimal residual disease of myelogenous leukemia ( MRD-L) , and to explore the biological mechanism of Fuzheng Toudu Qudu Recipe in promoting CD34+ to transform into DC in MRD-L patients. Methods Bone marrow mononuclear cells ( BMMC) were separated from the bone marrow of acute myeloid leukemia patients at complete remission stage by using Ficoll centrifugation. CD34+ cells were isolated by using immuno-magnetic mircobeads method, and then were cultured with various concentrations of Chinese medicine medicated serum and cytokines in vitro for the induction of DC. The morphologic characteristics of DC were observed with the inverted phase contrast microscope, and the expression levels of DC surface molecules such as CD83, CD80, CD86, CD1a and HLA-DR were detected by using flow cytometry. On culturing day 0, 6 and 9, serum levels of IL-2 and sIL-2R of each group were measured by enzyme-linked immunosorbent assay ( ELISA). Results ( 1) Chinese medicine medicated serum combined with cytokines was effective on promoting CD34+ to differentiate into DC with typical morphology, and inducing DC to have high expression of CD80, CD83, CD86 and HLA-DR, which differed from those in fetal calf serum (FCS) group and blank rabbit serum group (P0.05) . At the same time point, combination groups had lower IL-2 content than the blank rabbit serum group (P<0.05 or P<0.01). Conclusion Fuzheng Toudu Qudu Recipe is effective on increasing serum content of IL-2 and reducing sIL-2R content, and the changes of cytokine contents are more obvious along with the maturity of DC, which indicates that the recipe plays positive effect in the process of promoting CD34+cells to differentiate into DC.

ABSTRACT
Levels of soluble interleukin-2 receptor alpha (sIL-2Ralpha) are known to increase in the sera of patients with certain malignancies, including malignant lymphoma. This study aimed to assess the clinical significance of the sIL-2Ralpha level in non-Hodgkin's lymphoma (NHL). We used ELISA to measure the sIL-2Ralpha levels in 48 newly diagnosed and untreated patients with NHL and evaluated the correlation between the sIL-2Ralpha levels and clinical characteristics and the International Prognostic Index (IPI). We monitored serum sIL-2Ralpha in 7 patients to compare the changes in their clinical progress with these levels. High levels of serum sIL-2Ralpha (> or =2,000 U/mL) correlated well with parameters defining the high risk group according to the IPI, i.e., high tumor burden at diagnosis (stage III+IV) and lactate dehydrogenase > or =472 U/L. The levels were also associated with B symptoms, bone marrow involvement, and poor response to therapy. The sIL-2Ralpha level decreased during complete remission and was elevated during disease progression or relapse. A high level of sIL-2Ralpha was significantly associated with a low survival rate. These results suggest that serum sIL-2Ralpha might be useful as a biomarker for evaluating the prognosis of patients with NHL at the time of diagnosis and during therapy. A well-controlled, large-scale study is needed to clarify the clinical significance of sIL-2Ralpha in specific groups of NHL.

ABSTRACT
@#ObjectiveTo investigate the immune tolerance function and significance of allogene bone marrow injection to the small intestines transplantation of rats.MethodsInbreeding line rat F344/N and Wistar/A were selected to perform heterotopic graft of the whole small intestine. 7 days before allogene transplantation, donator bone marrow cells (BMC) were injected into thymus of acceptor (the testing group). According to the isogene and allogene rat transplant model, it was comprehended whether injecting allogene donator marrow into acceptor thymus could decrease the acute rejection after transplantation.Results3, 5 or 7 days after allogeneic rat dystopia whole small intestine transplantation, typical reject reaction appeared, but there was no reject reaction in isogenome and testing group. 3 days after allotransplantation, serum soluble interleukin-2 receptor (sIL-2R) and tumor necrotic factor-α (TNF-α) levels were significantly higher than the other groups (P<0.01). The level of serum sIL-2R and TNF-α in the allogene marrow injecting group were only slight higher on the 3rd or 5th day, and getting downtrend, and there was no significant difference compared with isogenic transplantation group.ConclusionAllogenic donator bone marrow intrathymic injecting into acceptor 7 days before small intestina transplantation, can reduce the reject reaction after the grafting. The levels of serum sIL-2R and TNF-α can be selected as a sensitive early diagnosis index of acute rejection after small intestine transplantation.
ABSTRACT
BACKGROUND: The cell-mediated immune response plays an important role in tuberculosis. After being activated by mycobacterial antigens, T lymphocytes express a high affinity receptor (IL-2R) for interleukin-2 (IL-2) on their own surface and release a soluble fraction of the IL-2 receptor (sIL-2R) from the cell membrane into the circulation. Neopterin is a metabolite of guanosine-triphosphate, which is produced by stimulated macrophages under the influence of IFN-gamma with a T lymphocyte origin. Therefore, the utility of sIL-2R, IFN-gamma and the neopterin levels as immunologic indices of the cell-mediated immune response and severity of disease in patients with pulmonary tuberculosis was assessed. METHOD: The serum sIL-2R, IFN-gamma and neopterin levels were measured in 39 patients with pulmonary tuberculosis, 6 patients with tuberculous lymphadenitis prior to treatment and 10 healthy subjects. The serum and pleural sIL-2R, neopterin and ADA levels were measured in 22 patients with tuberculous pleurisy. The patients with pulmonary tuberculosis were divided into a mild, moderate and severe group according to the severity by ATS guidelines. To compare the results from these patients with those of the pretreatment levels, the sIL-2R, IFN-gamma and neopterin levels were measured in 36 of the 39 patients(1 patient, expired; 2 patients were referred to a sanitarium) with pulmonary tuberculosis after 2 months of treatment. RESULTS: 1) The serum sIL-2R and IFN-gamma levels were elevated in patients with tuberculosis when compared to those of healthy subjects (0.05). The neopterin concentration in the serum was significantly lower in patients with pulmonary tuberculosis(2967+/-2132.8 pg/ml) than in healthy controls(4949+/-1242.1 pg/ml)(p0.05), 41 52.8 pg/ml to 22+/-23.9 pg/ml(p<0.05), respectively, after 2 month of treatment. The mean serum neopterin levels increased from 3158+/-2272.6 pg/ml to 3737+/-2307.5 pg/ml(0.05) after a 2 month of treatment. These findings were remarkable in the severe group of pulmonary tuberculosis with a clinical correlation. 4) In the patients with tuberculous pleurisy, the serum sIL-2R and ADA were significantly higher than those in the pleural fluid, However, the neopterin levels in the sera and pleural effusion were similar. CONCLUSION: On the basis of this study, sIL-2R, IFN-gamma and neopterin measurements may not only provide an insight into the present state of the cell-mediated immune response, but also serve as parameters monitoring of the prognosis of the disease, particularly in patients with severe pulmonary tuberculosis. In addition, an assay of the pleural sIL-2R levels might signal a stimulated local immunity including T cell activation in the tuberculous pleural effusion.

ABSTRACT
BACKGROUND: A soluble form of interleukin-2 receptor (sIL-2R) is released from activated T cells. Serum sIL-2R levels are elevated in some hematological malignancies and could be used to assess disease activity and prognosis. MATERIAL AND METHODS: To define clinical usefulness and significance as a marker predicting disease progress in chronic myeloproliferative disorders, the serum levels of sIL-2R were measured in 40 cases of chronic myelogenous leukemia (CML; 25 chronic phase, 7 accelerating phase, 8 blastic phase), 3 cases of polycythemia vera (PV), 5 cases of essential thrombocythemia (ET) and 4 cases of idiopathic myelofibrosis (MF) and in 37 cases of healthy subjects using sandwich enzyme immunoassay. RESULTS: Serum sIL-2R levels in the patients of CML, PV, ET, and MF were higher compared with the normal healthy controls. In CML, serum sIL-2R levels in the patients of blastic and accelerating phases were significantly higher than those of chronic phase. In CML of chronic phase, serum sIL-2R levels at diagnosis were related to WBC count but not to other clinical and hematologic paramaters. The leukemic cells of one patient with lymphoblastic phase of CML expressed IL-2R (CD25). Among 4 patients of CML with sIL-2R levels above 2,000U/mL at diagnosis, transformation to blastic crisis was noted in 3 patients and 2 patients died within 1 year after diagnosis. But among 11 patients of CML with sIL-2R levels below 2,000U/mL at diagnosis, only 2 patients experienced blastic crisis and died within 1 year after diagnosis. CONCLUSION: This study indicated that serum sIL-2R levels were high in chronic myeloproliferative disorders, and that increasing levels of serum sIL-2R might be useful to predict disease progress. Further studies including more patients and longer follow-up may substantiate serum sIL-2R as a prognostic indicator in CML.

Interleukin-5 (IL-5), which is known to be an activator of human eosinophil, increases in IgA nephropathy. In order to find out the relationship between activated eosinophil function and the pathogenesis of Henoch-Sch nlein purpura (HSP) and IgA nephropathy, serum esosinophil cationic protein (ECP) was analyzed using a monoclonal antibody Besides, the soluble IL-2 receptor (sIL-2R) was analyzed to clarify if there was a positive correlation between T cells and activated eosinophils. As anticipated, the levels of ECP, in detail, were significantly higher among HSP patients with a mean of 9.7+/-1.8microgram/L than in a control group with a mean of 4.6+/-0.7microgram/L. The HSP patients were also classified as one group with normal urine and another group with abnormal urine. The latter showed higher levels of ECP than the former. On the other hand, the levels of ECP were higher in IgA nephropathy patients than in the control group; however, there was no significance in statistics. The sIL-2R levels were higher in HSP patients than those in serums of IgA nephropathy patients and the control group. Thus, this study came to a conclusion that the activated eosinophil might be one of the pathogeneses in HSP but not in IgA nephropathy.

BACKGROUND: It was recently shown that human atherosclerotic plaque contains large numbers of T lymphocytes : this indicates that immune and inflammatory mechanism may be important factors in the pathogenesis of atherosclerosis. By measuring the soluble interleukin 2 receptor(sIL-2R) level we can evaluate the activation of T lymphocyte. The purpose of this study is to evaluate relationship between T cell activation and ischemic heart disease by measuring the soluble interleukin 2 receptor (sIL-2R) level in patient with ischemic heart disease. METHOD: Seventy-two patients(40 males and 32 female, mean age : 56.5+/-9.9 years) who were taken coronary angiography were included in this study. Among them, 49 patients showed abnormal coronary angiographic findings and 23 patients showed normal coronary angiographic findings. Ten mililiters of arterial blood was drawn at the time of coronary angiography. The blood was allowed to coagulate and then the serum was removed and tested in duplicate for soluble interleukin 2 receptor (sIL-2R) level by ELISA. RESULTS: 1) The soluble interleukin 2 receptor (sIL-2R) level was significantly different between abnormal coronary angiographic findings and normal coronary angiographic findings (P 0.05), but showed increasing tendency with clinical severity. 3) According to numbers of involved coronary vessels, soluble interleukin 2 receptor (sIL-2R) level was not significantly different between single vessel disease group and multivessels disease groups (p > 0.05). CONCLUSION: T lymphocyte activation, as reflected in elevated soluble interlekin 2 receptor (sIL-2R) level, is frequent in patient with ischemic heart disease. In the further we will investigate relationship between clinical diagnosis of ischemic heart disease of the numbers of involved coronary vessels and T cell activation.
