Phytochemical investigation of the roots of Scrophularia buergeriana Miq. (Scrophulariaceae), resulted in the isolation of a new iridoid derivative named as buergerinin (1). Its structure was elucidated as rel-(1R, 5R, 6R)-(2-oxa-bicyclo[3.3.0]oct-7-en-6, 7-diyl)dimethoxypropane based mainly on MS and 1D and 2D NMR spectroscopic analyses.

In order to study the chondrogenic phenotype differentiation of adult sheep bone marrow-derived mesenchymal stem cells (MSCs) in a defined medium as potential seed cells for cartilage tissue engineering. MSCs were isolated by density centrifugation with Percoll solution from bone marrow aspirated from sheep iliac crest. The third passage of MSCs were induced with H-DMEM containing TGF-beta3, IGF-I, Dexamethasone and VitC. The shape and ultrastructure of cells were observed, toluidine blue stain for GAG and immunohistochemistry for type II collagen were applied for chondrogenic phenotype identification. After 14 days of induction, MSCs changed from a spindle-like appearance to a polynal shape, a large amount of endoplasmic reticulum, Golgi complex and mitochondria were observed, and the differentiation of MSCs chondrogenic phenotype was verified by positive staining of toluidine blue and immunohistochemistry. MSCs derived from bone marrow can differentiate to chondrogenic phenotype when induced in vitro and can be used as optimal seed cells for cartilage tissue engineering.

Objective:To analyze the characteristics of infectious diseases from neurology ward and provide reference for the treat-ment. Methods:The consultation record of the neurological patients who suffered infection diseases were retrospectively summarized from January 2011 to December 2013. All the consultation were performed by clinical pharmacists. SPSS 19. 0 software was used to an-alyze the adoption and prognosis of the outcomes. Results:In 439 consultation cases,256 patients(58. 31%)were older than 65 years. Most of the cases were respiratory infection(294 cases,65. 33%),urinary tract infection(40 cases,8. 89%)and intracranial infection(37 cases,8. 22%). There were 510 strains of bacteria isolated by culturing,in which 362 strains were gram-negative bacte-ria(70. 98%),127 strains were gram-positive bacteria(24. 90%)and 21 strains were fungi(4. 12%). The top five of pathogenic bac-teria were Pseudomonas aeruginosa(125 stains,24. 51%),Acinetobacter baumannii(93 stains,18. 24%),Staphylococcus aureus(88 stains,17. 25%),Staphylococcus aureus(68 stains,13. 33%)and Escherichia coli. (32 stains,6. 27%). The detection rates of ESBLs of K. pneumonia and E. coli were 61. 36% and 75. 00%,respectively. Among 125 strains of P. aeruginosa,the sensitive rate to meropenem and inipenem was 65. 8% and 70. 6%,respectively. A. baumannii was highly multidrug resistant,and 21 strains (22. 58%)with pan-drug resistance were isolated. Gram-positive bacteria were highly sensitive to vancomycin and teicoplanin. Totally 35 strains(52. 24%)of MRSA were isolated. The complete adoption rate of consultation opinion was 84. 74%(372 cases),the partial adoption rate was 7. 28%(32 cases),and 35 cases(7. 97%)were declined. In all the adopted cases(319 cases,78. 96%)showed effectiveness. In the linear correlation analysis,the consultation adoption and therapy outcomes had significant correlation(P<0. 01). Conclusion:Clinical pharmacists can improve the efficiency in anti-infection therapy and play important roles in the treatment of infec-tious diseases in neurology ward,especially in the treatment of drug-resistant bacterial infections.

Objective To evaluate the efficacy and safety of autologous hematopoietic stem cell transplantation (AHSCT) in patients with relapsed and refractory malignant lymphoma. Methods The clinical data of 10 patients (6 males and 4 females) with relapsed (4 cases) and refractory (6 cases) malignant lymphomas who received AHSCT in General Hospital of Jinan Military Command from August 2011 to June 2015 were analyzed retrospectively. The median age was 34 years (20 ˉ50 years); 5 cases of Hodgkin lymphoma, 5 cases of non-Hodgkin lymphoma. Before transplantation, all patients received several courses of radiotherapy or chemotherapy. High dose of cytoxan combined with G-CSF were used to mobilize peripheral hematopoietic stem cell, and preconditioning regimen included BEAM, CBV or TBI. Results The median mononuclear cell of 10 patients was 7.385 × 108/kg. Complete remission was achieved in 8 patients after transplantation, and 2 cases relapsed. Median follow-up time was 18 months (20ˉ50 months). The overall survival rate and disease-free survival rate both were 80%(8/10). All patients had nausea, vomiting, diarrhea, oral mucositis and other adverse reactions, which could be tolerated. Conclusion ASHCT is an effective and safe method for treatment of relapsed and refractory malignant lymphomas.
