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.

OBJECTIVE: To investigate the characteristics of syndromes of phlegm and blood stasis in patients with coronary heart disease by multiple statistical methods of matching matrix, factor analysis and clustering analysis, and to provide some references for classification and normalization of diagnosis of syndromes of phlegm and blood stasis of coronary heart disease. METHODS: The correlations among 46 kinds of symptoms in syndrome of non-phlegm and non-blood stasis, syndrome of blood stasis, syndrome of phlegm and syndrome of phlegm-blood stasis blocking in 200 patients with coronary heart disease were analyzed by matching matrix, factor analysis and clustering analysis. RESULTS: The manifestations of tongue and pulse in syndromes of phlegm and blood stasis were significantly different from those in syndrome of non-phlegm and non-blood stasis. The pathogenesis of viscera in syndromes of phlegm and blood stasis lied in the heart and kidney, and the syndrome of deficiency of heart qi was the most common one while the syndrome of deficiency of kidney qi took the secondary place. The syndrome of phlegm was often accompanied by syndrome of deficiency of spleen qi. Only 15 ones of 46 clinical symptoms showed high frequency in concomitant appearance in syndrome of blood stasis, syndrome of phlegm and syndrome of phlegm-blood stasis blocking. Apart from having the common symptoms in syndrome of deficiency in origin, the syndrome of phlegm especially showed white and greasy fur and slippery pulse as well as distention and fullness of chest and abdominal distension; the syndrome of blood stasis showed purplish tongue and ecchymosis on tongue as well as fixed pain; and the syndrome of phlegm-blood stasis blocking showed the main symptoms of both syndrome of phlegm and syndrome of blood stasis. CONCLUSION: The statistical methods of matching matrix, factor analysis and clustering analysis are convenient, and can definitely indicate the clinical characteristics and syndrome differentiation of viscera of different syndromes of phlegm and blood stasis, which are beneficial to further research of diagnosis and differentiation of such syndromes of coronary heart disease.

To investigate the relationship between the plasma biomarker proteins and the states of Zang-Fu organs in patients with phlegm or blood stagnation syndromes due to hyperlipidemia and atherosclerosis.
