Objective To investigate the cytokine spectrum of cultured human amniotic-derived mesenchymal stem cells (A-MSC) for understanding its basis of molecular biology in hematopoietic in vitro.Methods Their hematopoietic cytokines expression was analyzed using RT-PCR in the mRNA level. Results It showed that in vitro subcultured human amniotic-derived mesenchymal stem cells were capable to express many important hematopoietic cytokines such as LIF, SCF, M-CSF, G-CSF, GM-CSF, IL-3, IL-6, IL-11 and so on. Conclusion Production of abundant of hematopoietic cytokines by human amniotic-derived mesenchymal stem cells may be effective for hematopoietic support and HSC transplantation.

Objective To examine the change of body weight (BW) and blood pressure (BP) in obese rats, clarify relationships between BP and BW and other factors. Methods Male Spraque-Dawley rats were fed either with normal diet (ND) or high calorie diet (HC) for 20 weeks. BW and BP of tail artery were observed biweekly and tetraweekly respectively; serum leptin and fasting insulin (FINS) were detected by enzyme-linked immunoadsordent assay (ELISA) and radioimmunoassay (RIA) respectively. Fasting plasma glucose (FPG) and free fatty acid(FFA) were measured by conventional means. Results BW, abdominal fat weight (AFW), ratio of abdominal fat weight to body weight (RF/W), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum levels of leptin and FINS, FPG, FFA increased in the HD group after 20 weeks diet intervention (P＜0.05 or P＜0.01). SBP was strongly correlated with BW, leptin, FINS and FFA (P＜0.05), DBP was correlated with FFA (r=0.47, P＜0.05). In addition, leptin was positively correlated with BW, AFW, RF/W, FINS and FFA (P＜0.05 or P＜0.01). Conclusion In this study of high calorie-diet induced rats, the gain of BW is accompanied by increased BP. The obese rats have hyperleptinemia, hyperinsulinemia, hyperglycemia and dyslipidemia which may have important effects on the development of obesity-related hypertension. RF/W is the key factor in which affect serum leptin level.

To optimize the growth condition for the established gene engineer bacteria express cardiac troponin-I(cTnI) and to obtain purified cTnI as an antigen to produce clinical assay kits used in acute myocardial injury(AMI) diagnosis.Plackett Burman Design(PBD) was applied to select the factors which effect the expression of cTnI in Escherichial coli(E.coli) mostly.Induction time,pH and KCl were proved influenced expression of cTnI notably.Afterward,Response Surface Methodology(RSM) as second step to optimize the selected three factors,an equation was deduced to predict the percent of cTnI.In the most optimized condition,the percent of cTnI can reach to 26% of total cell protein.The procedures of purification included ammonium sulfate deposition and DEAE Cellulose ion exchange chromatography.SDS-PAGE shows that purified cTnI contain one band.cTnI could be used to immune animals as an antigen to produce monoclonal antibodies with high affinity and specificity.It maybe as calibrators to harmony the difference assays of cTnI measurement in clinical.

As one of the important active components of traditional Chinese medicine (TCM), plant origin active proteins have many significant pharmacological functions. According to researches on the plant origin active proteins reported in recent years, pharmacological effects include anti-tumor, immune regulation, anti-oxidant, anti-pathogeny microorganism, anti-thrombus, as well as hypolipidemic and hypoglycemic activities of plant origin were reviewed, respectively. On the other hand, the analytical methods including chromatography, spectroscopy, electrophoresis and mass spectrometry for plant origin proteins analysis were also summarized. The main purpose of this paper is providing a reference for future development and application of plant active proteins.
