30 open-chest rabbits were randomly divided into 3 groups. In group Ⅰ the left anterior descending coronary artery (LAD) was false ligated. Rabbits of group Ⅱ and Ⅲ underwent 30 minuts of LAD occlusion and 4h of reperfusion. After LAD ligated in group Ⅲ were intravenously administered nitroglycerin and in group Ⅰ and Ⅱ were sodium chloride. The level of plasme nitric oxide (NO), alpha-granule membrance protein (GMP-140) on the surface of platelet and thromboxane B_2 (TXB_2) were determined in some time points before and after operation. The results showed that the level of NO, GMP-140 and TXB_2 in group Ⅰ were not difference before and after operation. In group Ⅱ and Ⅲ the level of NO was significantly decreased and the level of the GMP-140 and TXB_2 were significantly increased after myocardial ischemia and reperfusion. Changes in group Ⅱ were more marked than that in group Ⅲ. There were close relation between the value of NO and the value of GMP- 140 and TXB_2. It suggested that NO inhibited platelet activation after myocardial ischemia-reperfusion in vivo.

The adsorption of methylene blue (MB) in plasma on cross-linked agarose beads entrapped activated charcoal (CAAC-I), cross-linked agarose coated activated charcoal (CAAC-II) and cross-linked agar beads entrapped attapulgite (CAA) was tested in this study. These adsorbents are intended to be applied to blood purification for eliminating MB from virucidal MB-phototrated plasma units. The experimental results indicated that the adsorption of MB in plasma on CAAC-I and CAA was quick and efficacious, but it was slower on CAAC-II. The relationship between the adsorption time and the adsorption rate was examined with reference to the plasma with a specific concentration of MB flowing over a certain volume of CAA. A flow rate of about 1 ml.min-1 through 10 ml CAA at 25 degrees C could eliminate more than 95% of the MB in 200 ml human plasma (1 mumol.L-1).

By preventing mesenchymal stem cells (MSCs) from adhering to precoated agarose to create a model of MSC suspension in vitro, we investigated anoikis in MSCs and the role of caspase-3 in the anoikis. The cultured MSCs were randomly divided into 3 groups: the anoikis group, caspase-3 inhibitor group and control group. Before experiment, we coated dishes with 1.5 % agarose; in the anoikis group, MSCs were put into the precoated dishes; and in the inhibitor group, caspase-3 inhibitor and MSCs were also put into the precoated dishes; but there were not intervention in the control group. MSCs were collected at 2 h, 6 h, 12 h and 24 h. The alteration of caspase-3 activity was evaluated by caspase-3 fluorometric assay and western blot analysis. The apoptosis rates were detected by flow cytometry. MSCs were round and suspended sufficiently in the anoikis and inhibitor groups. Caspase-3 fluorometric assay showed that there were significant differences in statistics between the anoikis group and the others (P<0.05). Western blot analysis discovered that caspase-3 expression in the anoikis group was more than that in the control and inhibitor groups (P<0.05). Flow cytometry showed that the apoptosis peak appeared in all the three groups, but it increased dramatically in the anoikis group. The apoptosis rates in the inhibitor and control groups were low and stable. And there were significant differences in statistics between the anoikis group and the others (P<0.05). MSCs will undergo anoikis in suspended condition if they are separated from the extracellular matrix. Caspase-3 inhibitors can suppress caspase-3 activity and reduce the apoptosis rate significantly. Caspase-3 plays a vital part in induced MSC anoikis in vitro. MSCs suspension culture system might be set up with argorose and caspase-3 inhibitor.

BACKGROUND: Tumor necrosis factor-α (TNF-α) is one of important cytokines to promote the maturation of dendritic cells. Blockage of TNF-α action by binding with soluble tumor necrosis factor receptor 1 (sTNFR1) may arrest dendritic cells in an immature state and induce stable, long-term tolerance. OBJECTIVE: To construct the lentiviral vectors carrying sTNFR1 gene and investigate sTNFR1 expression in immature dendritic cells. METHODS: Total RNA of human peripheral blood mononuclear cells was taken as a template. The sTNFR1 gene fragment was amplified by RT-PCR, subcloned to the lentiviral vectors pXZ208, and ligated to the enhanced green fluorescent protein (eGFP) reporter gene to establish lentiviral vector, called pXZ9-sTNFR1. DNA sequencing was performed for lentiviral vector identification. Lentivirus was prepared by transfection of 293 FT cells with pXZ9-sTNFR1. Viral titer was determined by eGFP expression. C57BL/6 mouse bone marrow-derived dendritic cells were in vitro cultured with low-dose granulocyte-macrophage colony stimulating factors and interleukin 4. On day 5 of culture, immature dendritic cells were transfected with pXZ9-sTNFR1 recombinant lentiviral supernatant, sTNFR1 transcription was detected by RT-PCR, sTNFR1 protein expression by Western blot analysis. Following sTNFR1 gene modification and lipopolysaccharide stimulation, the phenotype characteristics of dendritic cells were observed. RESULTS AND CONCLUSION: Recombinant plasmid pXZ9-sTNFR1 was successfully constructed. Twenty-four hours after 293 FT cell transfection, eGFP expression was observed and viral titer was over 10<'6> U/L. RT-PCR demonstrated that pXZ9-sTNFRl-transfected immature dendritic cells showed sTNFR1 positive expression. Western blot analysis revealed that sTNFR1 protein appeared in the immature dendritic cells and supernatant following 293 FT cell transfection. On day 5 of culture, dendritic cells expressed low level of class Ⅱ major histocompatibility complex (MHC Ⅱ), as well as CD40, CD86, CD80, molecules. However, following lipopolysaccharide stimulation, dendritic cells expressed high level of MHC Ⅱ, as well as CD40, CD80, and CD86, molecules, exhibiting the phenotype characteristics of mature dendritic cells. But after sTNFR modification, the expression level of MHC Ⅱ, as well as CD40, CD80, and CD86, molecules was not altered obviously. Lentiviral vectors carrying sTNFR1 gene and eGFP reporter gene were successfully constructed, and recombinant lentiviral plasmids with high titer were acquired. Following high efficacy of lentiviral gene transfection, immature dendritic cells stably express sTNFR1 mRNA and protein, which prevents immature dendritic cells from activation by exogenous lipopolysaccharide and maintains the immature state.

BACKGROUND:There are several reports about the application of fresh bone marrow aspirate being injected directly to repair partial ligament injury, but the application about fresh bone marrow aspirate directly being planted on scaffolds to build tissue-engineered ligament is rarely mentioned.
OBJECTIVE:To evaluate the feasibility of applying fresh bone marrow aspirate planted directly on scaffolds to construct tissue-engineered ligament
METHODS:We constructed fibroin fiber/smal intestinal submucosa composite scaffold, then planting fresh bone marrow directly to built bone marrow seeding group and planting seed cel s (bone marrow mesenchymal stem cel s) on the scaffold to built cel seeding group. The control group had no treatment. After that, we detected the density of cel adhesion, cel proliferation ability and extracel ular matrix secretion. Then, the composite in the bone marrow seeding group was implanted into the broken anterior cruciate ligament in rabbits, and material biocompatibility in vivo was evaluated after 12 weeks.
RESULTS AND CONCLUSION:After 4 hours of incubation, bone marrow seeding group was significantly higher than the cel seeding group in cel adhesion density and proliferation rate (P<0.05). Bone marrow seeding group and cel seeding group showed higher type I, III col agen secretion compared with the control group (P<0.05), but the col agen secretion of bone marrow seeding group and cel seeding group showed no significant difference. Composite cel scaffold implantation in vivo did not cause fatal immune rejection and severe inflammatory reaction, and no significant ligament regeneration and vascularization occurred. These findings indicate that fresh bone marrow aspirate can be seeded directly on scaffolds to construct tissue-engineered ligament, and the short-term biocompatibility in vivo is good.
