BACKGROUND:Because of their immunological properties, bone marrow mesenchymal stem cells transfusion is developed as a new treatment for refractory graft-versus-host disease. OBJECTIVE:To analyze the safety and curative effect of bone marrow mesenchymal stem cells transfusion on treating different organ damages in graft-versus-host disease after al ogeneic hematopoietic stem celltransplantation. METHODS:Eight patients with malignant hematologic disease were included in this study. The patients developed severe steroid-resistant graft-versus-host disease after al ogeneic hematopoietic stem celltransplantation and received transfusion of mesenchymal stme cell(1×106 of immunosuppressive agent. RESULTS AND CONCLUSION:For the total y eight patients, six got response (two cases of complete remission, and four cases of partial remission) and two showed no remission. Four of five cutaneous damages were ameliorated and one showed no effect. For three cases of oral graft-versus-host disease, two acquired complete remission and one showed partial remission. Two cases of liver graft-versus-host disease and two cases of astro-intestinal graft-versus-host disease obtained complete remission. No response was displayed to three cases of ocular graft-versus-host disease, one case of bronchiolitis obliterans, and one case of urinary graft-versus-host disease. In the median fol ow-up of 28 months (7-62 months), three patients developed posttransplant lymphoproliferative disorders within 3 months after mesenchymal stem cells transfusion. Administration of mesenchymal stem cells is safe for treatment of severe graft-versus-host disease after al ogeneic hematopoietic stem celltransplantation. Mesenchymal stem cells transfusion may be a promising/kg) together with the primary therapy therapy for refractory cutaneous , astro-intestinal, liver and oral graft-versus-host disease but not for pulmonary, ocular and urinary graft-versus-host disease. Whether mesenchymal stem cells transfusion is associated with posttransplant lymphoproliferative disorders needs more case data.

AIM: To detect the protein expression of TIMP3 and RUNX3 in bone marrow mononuclear cells (BMMCs) from acute leukemia (AL) patients and to investigate the relationship between the methylation status of genes and their expressional levels. METHODS: Protein expression of TIMP3 and RUNX3 in 50 samples of BMMCs and 10 samples of peripheral blood mononuclear cells (PBMCs) from healthy volunteers was detected by Western blotting. The prognostic factors related to AL and data from methylation specific polymerase chain reaction were also analyzed. RESULTS: The expression level of RUNX3 with methylation was less than that without methylation in BMMCs from AL patients. The complete remission (CR) rate was related to RUNX3 expression and blasts in bone marrow (BM). BMMCs from patients with silencing of RUNX3 and higher blasts in BM had a lower CR rate. CONCLUSION: Absence of RUNX3 protein expression resulting from methylation of RUNX3 promoter probably plays a role in the pathogenesis of AL and is of value in prognosis. No relationship between methylation of TIMP3 promoter and the pathogenesis of AL is observed.

The effects of protein kinase C (PKC) on the tension and the activity of voltage-dependent delayed rectifier potassium channel (K(y)) were examined in normal and passively sensitized human airway smooth muscle (HASM), by measuring tones and whole-cell patch clamp techniques, and the K(v) activities and membrane potential (E (m)) were also detected. The results showed that phorbol 12-myristate 13-acetate (PMA), a PKC activator, caused a concentration-dependent constriction in normal HASM rings. The constriction of the passively sensitized muscle in asthma serum group was significantly higher than that of the normal group (P<0.05), and the constrictions of both groups were completely abolished by PKC inhibitor Ro31-8220 and calcium channel inhibitor nifedipine. K(v) activities of HASM cells were significantly inhibited by PMA, and the E (m) became more positive, as compared with the DMSO (a PMA menstruum)-treated group (P<0.01). This effect could be blocked by Ro31-8220 (P<0.01). It was concluded that activation of PKC could increase the tones of HASM, which might be related to the reduced K(v) activity. In passively sensitized HASM rings, this effect was more notable.
