A case of mercury-induced Baboon syndrome is reported.A 31-year-old female presented with a 2-3 day history of pruritic symmetric erythematous papules on both axillas,popliteal fossa,buttocks and groins.The patient was exposed to a broken mercury thermometer two days before the onset of the eruption.Patch testing showed that the patient was sensitive to ammoniated mercury,mercury,mercuric chloride and mercurochrome.The mercury levels in serum and full blood reached the up limit of normal value three days after the onset,and gradually decreased over time.The patient was diagnosed with Baboon syn- drome caused by mercury according to the clinical manifestation and results from laboratory studies.

The objective of the study was to prepare and evaluate the quality of curcumin-piperinedual drug loaded self-microemulsifying drug delivery system(Cur-PIP-SMEDDS). Simplex lattice design was constructed using optimal oil phase, surfactant and co-surfactant concentration as independent variables, and the curcumin and piperine were used as model drugs to optimize Cur-PIP-SMEDDS formulation. In the present study, the drug loadings of curcumin and piperine, mean particle size of Cur-PIP-SMEDDS were made as indicators, and the experiment design, model building and response surface analysis were established using Design Expert 8. 06 software to optimize and verify the composition of SMEDDS formulation. The quality of Cur-PIP-SMEDDS was evaluated by observing the appearance status, transmission electron microscope micrographs and determining particle diameter, electric potential, drug entrapment efficiency and drug loading of it. As a result, the optimal formulation of SMEDDS was CapryoL 90-Cremophor RH40-TranscutoL HP (10:60:30). The appearance of Cur-PIP-SMEDDS remained clarified and transparent, and the microemulsion droplets appeared spherical without aggregation with uniform particle size distribution. The mean size of microemulsion droplet formed from Cur-PIP-SMEDDS was 15.33 nm, the drug loading of SMEDDS for Cur and PIP were 40.90 mg · g(-1) and 0.97 mg · g(-1), respectively, the drug entrapment efficiency were 94.98% and 90.96%, respectively. The results show that Cur-PIP-SMEDDS can increase the solubility and stability of curcumin significantly, in the expectation of enhancing the bioavailability of it. Taken together, these findings can provide the reference to a preferable choice of the Cur formulation and contribute to therapeutic application in clinical research.

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.
