OBJECTIVE: To investigate the curative effect of combined transplantation of bone marrow and umbilical cord blood of same sibling in children with β-thalassemia major.METHODS: Eight thalassemia major patients undergoing combined transplantation of bone marrow and umbilical cord blood of same sibling aged from 4.0 to 7.5 years, 5 boys and 3 girls, were recruited at the Department of Pediatrics, Nanfang Hospital,Southem Medical University from January 2005 to March 2009. The patients were classified into three classes according to Pesarothalassamia classification, class Ⅰ to class Ⅱ 7 cases and class Ⅲ 1 case. Donors ranged 1-4 years received 10 μg/kg per day of subcutaneous granulocyte colony-stimulating factor (G-CSF) for 5 consecutive days. Bone marrow was harvested on the fifth day. Bone marrow and umbilical cord blood of the same sibling then were transfused into the patient.RESULTS: Recovery of hematopoiesis was gained in all patients 4 weeks following transplantation. Seven patients suffered from infection of different degree. Four patients developed mild venous occlusive disease. Two patients developed grade Ⅰ acute graft-versus-host disease (GVHD), and one developed grade Ⅰ chronic GVHD. Seven patients were alive and one died of pulmonary infection and heart failure 32 days following transplantation.CONCLUSION: Combined transplantation of granulocyte colony-stimulating factor primed bone marrow and umbilical cord blood of same sibling in children with β-thalassemia major is safe and effective with promising results. However, complications should be paid high attention following transplantation.

Objective To determine the incidence, clinical manifestation and part of lymphokines which represent the balance of Th1 and Th2 in the role of the immunologic mechanisms for IRIS(immune restoration inflammatory syndromes)in patients initiating HAART(Highly Active Antiretroviral Therapy).Methods A prospective study of all patients initiating HAART was performed. A period of six months tracking initiating HAART was performed. The incidence of IRIS, time of occurrence and clinical disease spectrum were recorded. The main T lymphokines including IL-2, INF-γ, IL-4, IL-10 which on behalf of the balance of Th1 and Th2 were detected. To explore the immunopathologic mechanisms for IRIS, the levels of T lymphokines at pre-HAART, initiating HAART for 1 month, 3months and 6 months were compared in IRIS group and non-IRIS group, healthy group. Results A total of 212 patients were enrolled in this study. 59 patients were diagnosed as IRIS at a median of 21 days after HAART initiation (QR 19 days).The main disease spectrum included tuberculosis, herpes virus infections, pneumocystis jirovecii pneumonia. No matter in the IRIS group or non-IRIS group, the main lymphokines baseline of IL-2, INF-γ reduced and IL-4, IL-10 increased before HAART compared to healthy group (P ＜ 0. 05), which had the tendency to restore balance relations initiating HAART. The lymphokines levels had significant difference between baseline and 6 months initiating HAART (P ＜ 0. 05). The changed levels of lymphokines between IRIS group and non-IRIS group before HAART had significant difference compared to healthy group. IL-2, INF-γ increased level[(11.68 ± 2. 89) pg/ml vs (8.52 ±2.26) pg/ml; (22. 19 ± 6. 22) pg/ml vs (18.34 ±5. 35) pg/ml] and IL-10 decreased level [(19. 21 ± 4. 03) pg/ml vs (23. 19 ± 5.92) pg/ml] had significant difference between IRIS group and non-IRIS group initiating HAART I month(P ＜0. 05). Conclusions The incidence of IRIS during 6 months initiating HAART in HIV/AIDS was 27. 8%, IRIS usually occurred in 1 month initiating HAART. The most common disease spectrum was infectious disease, including tuberculosis and herpes virus infection. Lymphokine of Th1 and Th2 existed unbalance in IRIS group and non-IRIS group before HAART. The unbalance tendency in IRIS group was more obvious. All lymphokines had the trend to recover balance. IL-2, INF-γ significantly increased and IL-10 significantly decreased, which might involve the occurrence of the IRIS.

BACKGROUND:Cytokines play an important role in the occurrence and development of graft-versus-host disease, but there is a current lack of reports on the association between cytokines and graft-versus-host disease after al ogeneic hematopoietic stem cel transplantation for treatment ofβ-thalassemia major.
OBJECTIVE:To investigate the association between cytokines and graft-versus-host disease after al ogeneic hematopoietic stem cel transplantation forβ-thalassemia major.
METHODS:We observed the dynamic variation of interleukin 6, interleukin 8, interleukin 12, tumor necrosis factor-αand macrophage migration inhibitory factor in 11 children withβ-thalassemia major before onset of graft-versus-host disease, when graft-versus-host disease occurred, at days 4 and 7 after onset of graft-versus-host disease, and when graft-versus-host disease disappeared.
RESULTS AND CONCLUSION:There was a significant difference in serum levels of interleukin-6, interleukin-12, tumor necrosis factor-α, macrophage migration inhibitory factor in different time points, and the highest levels of different cytokines appeared when graft-versus-host disease occurred, fol owed by those at 7 days after
graft-versus-host disease. There was a significant difference in serum levels of interleukin-8 in different time points, and the highest level appeared at 4 days after graft-versus-host disease. The dynamic expression of interleukin-6, interleukin-8, interleukin-12, tumor necrosis factor-α, macrophage migration inhibitory factor can estimate the immune function ofβ-thalassemia major patients who develops graft-versus-host disease after al ogeneic hematopoietic stem cel transplantation, and can be used as the immunobiology indicators for the early diagnosis of graft-versus-host disease.

Objective To study the effect of different dialysis modalities on pruritus in elderly maintenance hemodialysis patients.Methods Totally 51 patients were randomly divided into hemoperfusion combined with hemodialysis group (HD+ HP),hemodiafiltration group (HDF) and hemodialysis group (HD).Plasma β2-microglobulin(β2-MG) and intact parathyroid hormone (iPTH) were measured by means of radio immunoassay at pre and post dialysis,4 weeks and 8 weeks after dialysis,cutaneous pruritus was scored.The remission rate of itching was calculated at 8 weeks after dialysis.The parameters were compared among different groups.Results The level of plasma β2-MG was lower in HD+HP group after dialysis than pre dialysis [(13.48±3.05)mg/L vs.(16.27±4.73) mg/L,t＝2.044,P＜0.05],at 4 weeks and 8 weeks after dialysis,its levels were decreased to (10.97±3.25)mg/L(t＝3.808,P＝0.002)and (6.47±2.35)mg/L(t＝7.650,P＝0.000),respectively.The levels of iPTH were also found decrease from(887.5 ± 242.7)ng/L to (688.3 ±223.4)ng/L(t＝3.384,P＝0.004)at 4 weeks and (467.2±102.5) ng/L(t＝6.578,P＝0.000) at 8weeks after dialysis in HD+HP group (all P＜0.01).There were differences of the levels of plasma β2-MG and iPTH at 4 weeks and 8 weeks after dialysis in HDF group (all P＜ 0.05),but no differences of the levels of plasma β2-MG and iPTH during every period were found in HD group(all P＞0.05).The scores of cutaneous pruritus were decreased from (21.17± 5.01) scores to (13.37±2.85) scores(t＝ 5.580,P＝0.000)at 4 weeks and (8.52±4.38) scores(t＝7.838,P＝0.000)at 8 weeks after dialysis in HD+ HP group,and also the scores at 4 and 8 weeks after dialysis in HDF group (all P＜0.01),but there were no significant differences of the scores during every period in HD group (all P＞0.05).The remission rate of itching was better in HD+ HP group than in HDF group [88.24％ (15/17 cases) vs.58.82％ (10/17 cases),x2＝14.44,P＝0.000],better in HDF group than in HD group 23.53％ (4/17 cases) (x2 ＝4.37,P＝0.037).Conclusions HD+HP is superior to HDF in efficiently clear β2-MG and iPTH,and relief cutaneous pruritus,but HD can poorly clear β2-MG and iPTH or relief itching.

To investigate the dynamics of interleukin-21 (IL-21) cytokine in the Chinese HIV patients undergoing highly active antiretroviral therapy (HAAPT).Methods A total of 25 adults with chronic HIV infections,responding to combined highly active antiretroviral therapy (HAART) guideline criteria were enrolled for a 1-year follow-up.After signing an informed consent,20 mL blood was collected from each patient at the base line,6 month and 12 month,respectively.CD4 and CD8 cell count was quantified by flux cytometry,serum HIV RNA quantified by real time PCR and IL-21 concentrations by ELISA.Results IL-21 levels increased gradually during the follow-up but did not reach the healthy levels.IL-21 correlated positively with the CD4 cells but not with CD8 T cells.HIV RNA correlated negatively with CD4 cell count but did not show any relationship with the CD8 cells.Conclusion IL-21 has potential role in the immunopathogenesis of HIV,and might be an important factor in immune construction during HAART.

Although highly active antiretroviral therapy (HAART) can effectively reduce the HIV replication,complete recovery of CD4+ T cells does not always occur,even among patients with high virological control.Current researches on γ-chain cytokines have understood the biology and their crucial roles in initiating,maintaining,and regulating the immunologic homeostasis and the inflammatory processes.Due to the multiple functions such as the regulatory and effector cellular function in healthy and disease state,these molecules,their receptors,and their signal transduction pathways are promising candidates for therapeutic interference.The common γ-chain cytokines IL-2,IL-7,IL-15,and IL-21 are primary regulators of T cell homeostasis and thus have been considered prime immunotherapeutic candidates,both for increasing T cell levels/function and augmenting vaccine-elicited viral-specific T cell responses in immunocompromised AIDS patients.The objective of this review is to update the role of the common γ-chain cytokines IL-2,IL-7,IL-15,and IL-21 in HIV AIDS pathogenesis.

Objective To observe the Th17, IL-17 and Tr cells equilibrium state as well as their changes of HIV infected or AIDS suffered patients in one-year HAART treatment. Methods Select 33 HIV/AIDS patients received HAART treatment while 33 healthy volunteers as controls. Flow cytometry was used to analyze Th17 and Tr cells in venous blood at the time of pre-therapy, 6th, 12th month when IL-17 levels in serum are tested by ELISA. Results The ratio of Th17 cells in CD4 cells in HIV/AIDS patients and volunteers were (1.20±0.37)%, (2.50±1.03)%, (3.70±1.56)%, (4.70±1.43)%, respectively; The ratio of Tr cells were (9.16±3.33)%, (7.19±2.91)%, (5.53±1.88)%, (4.43±0.97)%, respectively; The levels of IL-17 in serum were (5.3±2.5) pg/ml, (7.7±2.4) pg/ml, (10.4±3.1) pg/ml, (17.7±6.6) pg/ml respectively. The Th17 cells' level was positively correlative with the amount of CD4 cells, negatively correlate with the count of viral load. However, the Tr cells level is positively correlative with the count of viral load, negatively relate to the quantity of CD4 cells. Conclusion HIV could make IL-17, Th17 cells and Tr cells lost their balance, but the immune equilibrium state may gradually recover after HAART treatment. Which indicates the IL-17, Th17 cells and Treg cells may play an important role in the pathogenesis of AIDS, and they are likely to be the effective indexes to observe the progress of AIDS and the treatment effect of highly active antiretroviral therapy(HAART).
