OBJECTIVETo investigate the inhibitory effect of bone marrow mesenchymal stem cells (BMSCs) on E coliinduced prostatitis in rats.
METHODSBMSCs were isolated, cultured and amplified by the attached choice method. Fifty SD rats were randomized into five groups of equal number: normal control, acute bacterial prostatitis (ABP) , chronic bacterial prostatitis (CBP), ABP + BMSCs, and CBP + BMSCs, and the animals in the latter four groups were injected with E. coli into both sides of the prostate under ultrasound guidance for 1 - 14 days to induce ABP and for 4 - 12 weeks to induce CBP. The control rats were injected with the same amount of PBS. Two weeks after injection of BMSCs into the prostates, pathomorphological changes in the prostate were observed under the light microscope and the mRNA and protein levels of IL-1β and TNF-α determined by RT-PCR and ELISA, respectively, followed by statistical analysis with SPSS 18.0.
RESULTSHistopathological evaluation showed typical pathological inflammatory changes in the prostates of the rats in the ABP and CBP groups, including glandular structural changes, interstitial edema, inflammatory cell infiltration, and fibrous hyperplasia, which were all remarkably relieved after treated with BMSCs. The mRNA and protein levels of IL-β ([0.829 ± 0.121] and [271.75 ± 90.59] pg/ml) and TNF-α ([0.913 ± 0. 094] and [105.78 ± 19. 05] pg/ml) in the ABP and those of IL-1β ([0. 975 ± 0. 114] and [265. 31 ± 71. 34] pg/ml) and TNF-α ([0. 886 ± 0. 084] and [107. 45 ± 26. 11 ] pg/ml) in the CBP groups were significantly higher than those in the control rats ([0. 342 ± 0.087] and [45.76 17. 99] pg/ml, P <0. 05); ([0.247 ± 0.054] and ([19.42 ± 7. 75] pg/ml, P <0. 01) as well as than those in the ABP + BMSCs ([0. 433 ± 0. 072] and [51. 34 ± 22. 13] pg/ml, P < 0. 05 ) ; ( [0. 313 ± 0. 076] and [28. 38 ± 8. 78] pg/ml, P < 0. 01) and the CBP + BMSCs group ([0.396 ± 0.064] and [56.37 ± 21.22] pg/ml, P <0.05); ([0.417 ± 0.068] and [29.21 ± 10.22] pg/ml, P <0.01).
CONCLUSIONInjection of BMSCs can reduce E coli-induced prostatic inflammation reaction, which.may be associated with its reduction of inflammatory cell infiltration and the expressions of IL-1β and TNF-α in the prostate tissue.

OBJECTIVETo evaluate the clinical efficacy of treating myelodysplastic syndrome (MDS) by hematopoietic stem cell transplantation (HSCT) combined with Chinese medical syndrome typing.
METHODSFrom July 2009 to July 2013, 6 MDS patients were treated with allo-HSCT combined with Chinese medical syndrome typing from HLA-identical sibling donors at Department of Hematology, Zhejiang Provincial Hospital of Chinese Medicine. Patients were classified as refractory anemia (RA, 2 cases), refractory anemia with ringed sideroblast (RARS, 1 case), refractory cytopenia with multilineage dysplasia (RCMD, 2 cases), and RA with excess blasts-I (RAEB-I , 1 case). Modified BuCy conditioning regimen was used in all 6 cases. Two patients received bone marrow transplantation (BMT), 1 patient received peripheral blood stem cell transplantation (PBSCT), and 3 patients received BMT + PBSCT. In order to prevent the occurrence of graft-versus-host disease (GVHD), all patients were treated with cyclosporine + methotrexate + mycophenolate mofetil. Different Chinese medical treatment methods (by syndrome typing) were given to patients according to different criticality of international prognostic scoring system (IPSS, 5 at moderate risk and 1 at high risk).
RESULTSAll 6 patients successfully reconstructed their hematopoietic system. The time from transplantation to ANC ≥ 0.5 x 10(9)/L and platelet (PLT) ≥ 20 x10(9)/L were 13 (9-15) days and 11 (9-22) days respectively. Main complications were GVHD. Acute GVHD (aGVHD) occurred in 4 cases, 3 cases of grade I and 1 case of grade II, and local chronic GVHD (cGVHD) occurred in 1 patient. All cases survived with median follow-up of 18 (11-58) months. The overall survival (OS) and disease-free survival (DFS) rate were 100%.
CONCLUSIONSHSCT combined with Chinese medical syndrome typing could improve clinical symptoms, reduce transplant as- sociated complications. So it was an effective treatment choice for MDS.

OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.
METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.
RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).
CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.
