Bone marrow-derived stem cells, mainly including hematopoietic stem cells, mesenchymal stem cells, multipotent adult progenitor cells, etc., are the most densely studied adult stem cells up to now. Recent findings indicate that adult stem cells have the potential to differentiate across lineage barriers and to adopt the expression profiles and functional phenotypes of cells unique to other tissues. This flexibility is termed "plasticity",which has posed challenges to conventional concepts. Meanwhile, it brings new hopes for the therapeutic application of cell engineering and tissue engineering. This review focuses on the biological features, the plasticity and its possible mechanisms, research method and potential clinical application of bone marrow-derived adult stem cells

Objective To establish a reversed HPLC method to determine the contents of gatifloxacin and tinidazole simultaneously. Methods ODS C_ 18 column (4.6mm?250mm,5?m) was used as an analytical column. The mobile phase consisted of 15% acetonitrile, 25% of methanol and 60% of 0.05mol/L KH_2PO_4 buffer,which contained 0.5% triethylamine and was adjusted to pH 3.5 by phosphoric acid. The flow rate was 1ml/min. The detection wavelength was 318nm. The column temperature was 30℃. 20?l of diluted sample solution was injected to the sampler. Results The calibration curve of gatifloxacin was linear in the range of 2~20?g /ml (r=0.999 6) ,and that of tinidazole was 2~20 ?g /ml (r=0.999 9). The recovery rates of them were 100.1% and 100.4%,respectively. RSDs of both drugs were less than 1.1 %. Conclusions The method is simple,accurate and sensitive and can be used to determine the two components simultaneously.

In order to study the mechanisms of high frequency stimulation ( HFS), we designed an in vitro device to deliver extracellular electrical stimulation to live cells in culture, using the same parameters as in the surgical treatment of Parkinson's disease (PD). The system was made of a 24 wells culture plate electrified with titanium wire bridges or two titanium wires placed parallel in a culture dish of 10 centimetres diameter. The extremities of the series of wells were connected to a constant current generator. The result showed that this system had no toxicity on GH3 and PC12 cell cultures. Preliminary experiences demonstrate that this system is suitable for the study with DNA and protein chip technologies.

Objective To study the immunodiagnostic potential of recombinant membrane protein Tetraspanin 2 of Schistosoma japonicum(rSjTsp2) as a diagnostic antigen. Methods The rSjTsp2 was expressed and purified as an antigen used in indirect ELISA to detect specific serum antibody against Schistosoma japonicum of rabbits that at different stages of infection, and the results were compared with those of ELISA using natural antigen (AWA) as antigen. Results The sensitivities of rSjTsp2-ELISA were 75.4% (46/61),77.6% (45/58) and 81.5% (44/54), respectively, 2, 4, 6 weeks after rabbits were infected with Schistosoma japonicum, meanwhile the sensitivities of AWA-ELISA were 68.9% (42/61),86.2% (50/58) and 88.9% (48/54), respectively. The sensitivity difference of two methods was not significant statistically (x2 = 0.652, 1.454,1.174, all P ＞ 0.05).Conclusions The rSjTsp2 is expressed successfully in vitro, and rSjTsp2 recombinant protein expressed in prokaryotic system has a certain application potential in immunodiagnosis.

Objective To analyze the clinical profiles of lupus mesenteric vasculitis (LMV).Methods Thirty-six SLE patients diagnosed with LMV and 72 SLE patients (1:2) without LMV at West China Hospital between October 2009 and January 2012 were enrolled.The imaging,clinical manifestation,laboratory examinations data were analyzed retrospectively.Quantitative differences were analyzed by the Student's t and Z tests and qualitative data were compared with Chi-square.P value less than 0.05 was considered as statistically significant.Results ① The prevalence of LMV in patients with SLE was 1.2％(36/3 051),while 47％(17/36) as the initial symptom of SLE.Thirty-six LMV patients were all female.The prevalence of abdominal pain was 78％(28/36),nausea or vomitting was 58％(21/36),abdominal distension was 50％(18/36),diarrhea was 47.2％ (17/36),intestinal perforation was 3％ (1/36) and incomplete obstruction was 8％ (3/36).Enhanced CT scan showed 81％(25/31) patients suffered from intestinal dilation and (or) mesenteric edema;SLEDAI (17±5),C3 (0.44±0.25) g/L,C4 (0.10±0.09) g/L,Z value on above items were 4.30,-3.85 and-2.94 respectively compared to SLE patients without LMV,and all P＜0.05,the differemces were significant.In addition,Also,the proportion of ANA and anti-ENA antibody showed no significant difference.68.6％(13/36) patients were also diagnosed with lupus nephritis;61％(22/36) patients were treated with methylprednisolone more than 200 mg/d resulting in relief of symptom.Conclusion Female patients with SLE may be more likely to suffer from LMV;Enhanced abdominal CT scan is still essential to the diagnosis of LMV.LMV is correlated with urinary system malfunction.LMV always occurs in active lupus with low C3 and C4 level.More than half patients should be treated with corticosteroid and cyclophosphamide pulse therapy.

BACKGROUND:Compared with single or composite biomolecular materials, decellulazied matrices are more biomimetic to natural ectocytic surroundings. So cel-secreted extracellular matrix is paid more and more attention in the field of tissue engineering, and the composition of these matrices are influenced by decellulezired preparation methods more or less. But there are few studies about the biological effect of different decellulazried methods on the extracellular matrix. OBJECTIVE:To investigate the composition of cel-secreted extracellular matrices in vitro by different decellularizing methods and their effects as surface modification on cytobiological reaction. METHODS:After the treatment of different decellularizing methods (freeze/thaw cycles, trypsin, weak alkal, detergents), the extracellular matrix was obtained and grouped into four kinds. The biological composition of the extracellular matrix was determined by ELISA assay. Then osteoblasts were seeded onto the four kinds of extracellular matrix surfaces. cells cultured normal y served as controls. The effect of extracellular matrix coatings on cellgrowth and differentiation were determined by MTT test and alkaline phosphatase activity test. RESULTS AND CONCLUSION:The residual components were the most in the freeze-thaw group, fol owed by the detergent and weak alkal groups, and the least in the trypsin group. Compared with the control group, the absorbance value of cells were lower in the freeze-thaw and detergent groups at days 3, 5, 7 after inoculation (both P<0.05);the alkaline phosphatase activity was lower in the trypsin group at days 5, 7 after inoculation (P<0.05), in the weak alkal group at 7 days after inoculation (P<0.05), and in the detergent group at days 3, 5, 7 after inoculation (P<0.05). Therefore, we can harvest more extracellular matrices by the freeze-thaw method, and the extracellular matrix coating synthesized by the freeze-thaw method is more helpful for cellgrowth than others.
