Objective To evaluate the effect of propofol on lung cell apoptosis induced by acute pulmonary thromboembolism (APTE) .Methods Forty male SD rats weighing 280-300 g were randomly divided into 5 groups ( n = 8 each) : group Ⅰ sham operation ( group S) ; group ⅡAPTE and 3 propofol groups ( group P1-3). APTE was produced by iv injection of auto-blood clots. Venous blood 0.2 ml was obtained from rat tail vein and placed in a sterile test tube which was kept in water bath at 37 ℃ overnight. The blood clot was cut into thrombi ( diameter 1 mm, length 5 mm) the next day. Fifteen thrombi in 2 ml of normal saline were injected into immediately after iv injection of auto-bloed clots. The animals were killed at the end of 4 h propofol infusion and lung specimens were obtained for determination of lung cell apoptosis rate by flow eytometry and expression of caspase-3, Bax, Bcl-2, Fas, FasL mRNA and protein by RT-PCR and Western blot.The expression of Bcl-2/Bax mRNA and protein was calculated. Results Compared with group S,APTE significantly increased the lung cell apoptosis rate, and expression of caspase-3, Bax, Fas, FasL and decreased the expression of Bcl-2 and Bcl-2/Bax. Propofol infusion significantly attenuated these APTE-induced changes. Conclusion Propofol can inhibit APTE-induced lung cell apoptosis by down-regulating the caspase-3, Fas and FasL expression and regulating the balance between Bcl-2 and Bax expression.

AIM: To construct a recombinant plasmid carrying enhanced green fluorescent protein and human vascular endothelial growth factor 121 gene and to detect its expression in rats mesenchymal stem cells (MSCs). METHODS: Human VEGF121 cDNA was amplified with polymerase chain reaction (PCR) from pCD/hVEGF121 and was inserted into the eukaryotic expression vector pEGFP-C1. The recombinant plasmid pEGFP/hVEGF121 was identified with PCR, double enzyme digestion and DNA sequencing. Then this recombinant plasmid was transfected into rat's MSCs with lipofectamine. The expression of EGFP and VEGF121 protein were detected with fluorescence microscope and immunocytochemical staining, respectively. RESULTS: The recombinant plasmid was confirmed with PCR, double enzyme digestion and DNA sequencing. The fluorescence microscope and immunocytochemical staining results showed that the EGFP and VEGF121 protein were expressed in MSCs 48h after transfection. CONCLUSIONS: The recombinant plasmid carrying enhanced green fluorescent protein and human vascular endothelial growth factor was successfully constructed and expressed positively in rat MSCs. It provides a good basis for further research on differentiation of MSC and VEGF gene therapy for ischemial cardiovascular disease.

ObjectiveTo induce human peripheral blood mononuclear cells differentiate into hepatocyte-like cells by hepatocyte growth factor (HGF) and fibroblast growth factor-4 (FGF-4) in vitro and determine whether PKH26 could be used to serve as an effective tracer for the cells,and observe the ability of transplanted hepatocyte-like cells differentiate into hepatic cells in nude mice.MethodsGroup A and B were set up respectively.In Group A,mononuclear cells were cultivated without hepatocyte growth factor (HGF) and fibroblast growth factor-4 (FGF-4) in cell culture.They were used as negative control group.In Group B,mononuclear cells were cultured with the administration of both HGF and FGF-4 to induce the differentiation into liver hepatocyte-like cells.The changes in cell morphology were observed and the expressions of AFP and CK 19 were detected by immunocytochemical staining in two groups at different times after induction.The hepatocyte-like cells differentiated from human peripheral blood mononuclear cells labeled by the fluorescent dye PKH26 injected into caudal vein in nude mice is experimental group.The nude mice injected with equal amount of normal saline in control group.The migration of the labeled cells into the liver are observed by the fluorescence microscope in the hepatic tissue sections of nude mice and the expressions of ALB were detected by immunocytochemical staining two weeks after the cells transplantation.ResultsCells in group B have a strong proliferative activity.It becomes large and oval,grows in colonies following induction.Cells in group A that showed spherical shape when peripheral blood mononuclear cells were just isolated are gradually becoming inconformity in morphology,spindle or fibroid,and a few cells are round:cells developed apoptosis and cracked following incubation.The expressions of AFP and CK19 were positive after induction in group B as detected by immunocytochemicat staining.Inversely,the expressions of AFP and CK19 were negative in group A after incubation.The experimental group showed numerous PKH26 labeled cells in the hepatic tissue sections of nude mice.But the control group did not show PKH26 labeled cells.The expressions of ALB were positive in the experimental group as detected by immunocytochemical staining after two weeks of the cells transplantation.ConclusionHuman peripheral blood mononuclear cells have the potential to differentiate into hepatocyte-like cells under the induction of HGF and FGF-4.Additionally,PKH26 is an effective tracer in hepatocyte-like cell transplantation.The hepatocyte-like cells settled in hepatic tissue begin to differentiate into mature hepatocyte after two weeks of the cells transplantation.It plays hepatic cells function and expresses alhnmin.

Objective To investigate the effects of Calpain inhibitor Ⅰ on glucocorticoid receptor and its transcript activation ability. Methods Raw-264.7 cells were treated respectively with Calpain inhibitor Ⅰ and dexamethasone or both for 24 h. The changes of glucocorticoid receptor were observed. COS-7 cells were co-transfected with PRsh-GR? and pMAMneo-CAT vectors, and then the effects of Calpain inhibitor Ⅰ on glucocorticoid receptor and its transcript activation ability were detected. Results The glucocorticoid receptors was decreased after Raw-264.7 cells were treated with dexamethasone for 24 h. Calpain inhibitor Ⅰ could inhibit this effect to some extent. Co-transfection experiment revealed that Calpain inhibitor Ⅰ could also promote glucocorticoid receptor transcript activation ability. Conclusion Calpain inhibitor Ⅰ can inhibit the down-regulation of dexamethasone on glucocorticoid receptor, but promote glucocorticoid receptor transcript activation ability.
