Objective　To construct a recombinant plasmid pcDNA3-sHLA-G1 expressing soluble HLA-G1. Methods　 Total cell RNA was extracted from the cell line Jeg-3 and the cDNA was amplified by RT-PCR； The cDNA fragment was inserted into the eukaryotic expressing vector pcDNA3 and the recombinant plasmid was identified by restriction endonucleases digestion and sequencing. Results　 After restriction endonucleases treatment and sequencing, it was confirmed that the pcDNA3-sHLA-G1 had been constructed successfully. Conclusion　 In this study, the recombinant plasmid pcDNA3-sHLA-G1 had been constructed successfully.

Objective:To investigate the relationship between the level of Bcl 2 protein in EB virus infected cells and the sensitivity of this cells to NK activity and apoptosis inducing factors.Methods:Antisense oligodexynucleotides(ODNs) were used to modulate the expression of Bcl 2 gene in Epstein Barr virus transformed B lymphoblastoid cell lines(EBV LCLs);then the change of cytotoxicity of natural killer cells and the sensitivity of apoptosis inducing elements(taking out growth factor ?dexamethasone)targeting EBV LCLs,were investigated.Results:The level of Bcl 2 expression in EBV LCLs has negative relativity with the cytotoxicity of NK cells to EBV LCLs(P

Objective To investigate the effect of portal hypertension (PH) on the activity of local renin angiotensin system(LRAS). Method The expression of local renin and local angiotensinogen mRNA in liver,splenic artery and vein of PH patients was detected with RT-PCR. Result Expression of local renin mRNA in the liver in control group was 0.19?0.12, significantly lower than that of splenic artery (0.45?0.12) and splenic vein (0.39?0.12) respectively(P

The petroleum ether fraction of ethanol extracts from Boenninghausenia sessilicarpawas isolated by combination of several chromatographic methods including silica gel, ODS, and Sephadex LH-20 column chromatography, and finally purified by preparative HPLC. The structures of the isolated compounds were identified based on the spectral data. As a result, 15 coumarin compounds were isolated and identified from the petroleum ether extraction. Their structures were determined as osthenon (1), murrangatin (2), 3-(1,1-dimethylallyl)-8-hydroxy-7-methoxycoumarin (3), xanthotoxin (4), isopimpinellin (5), chalepensin (6), isodemethylfuropinarine (7), imperatorin (8), phellopterin (9), heraclenol (10), byakangelicin (11), neobyakangelicol (12), chalepin (13), luvangetin (14), 3-(1, 1-dimethylallyl)-xanthyletin (15). Among them, compounds 1 - 3, 6 - 10 and 14 -15 were firstly isolated from B. sessilicarpa.
