Superantigens are potent activators of T cells,causing rapid and massive proliferation of T cells and superantigen-dependent-cell-mediated cytotoxicity with extremely low doses.However such antitumor effects lack selectivity.Thus with the methods including monoclonal antibody targeting or binding superantigens to the surface of tumor cells as well as genetic engineering,scientists have done lots of work on targeted therapy of malignancies with superantigen.

The brainstems of 6 rabbits were cut transversely in series and stained fornerve cells or myelin.The architecture of the parabrachial nucleus was studied.Be-sides general observation the length and width of 100 nerve cells in each of the 5nuclear areas chosen were measured and analysed statistically with the help of adigital computer.The following items were calculated:ratio of length to width,itsmean and 95% tolerance interval;area of nerve cells,its mean and 95% toleranceinterval;80% elliptical contour of normal bivariates for the length and width of thecells;cluster analysis of the more dispersed nuclear areas and 80% elliptical contourof each cluster. We concluded that the parabrachial complex consists mainly of 3 nuclei,viz.medial parabrachial nucleus,lateral parabrachial nucleus and magnocellularparabrachial nucleus.Dorsal to the medial parabrachial nucleus there is asmall area,which was tentatively called“d”area in the present study.The medial parabrachial nucleus lies medial to the brachium conjunctivum.Its cells are more or less round in shape,varying markedly in size and canbe clustered into 3 groups according to their size.The lateral parabrachial nucleusis located lateral to the brachium conjunctivum.Its cells are smaller than those ofthe medial nucleus,mostly spindle in shape.Some larger cells can also be seen scat-tered among the smaller ones and the process of clustering has yielded 2 groups ofcells.The magnocellular parabrachial nucleus can be seen in the middle range ofthe nuclear complex.It lies ventrolateral to the brachium conjunctivum with denselypacked large round cells.Its demarkation with the surroundings is sharp.A dorsalextension of this nucleus can be seen wedging between the brachium conjunctivumand the lateral parabrachial nucleus.Its cells are also large and compacted but arespindle in shape.Cells of the“d”area are small and round.Its relation with eitherthe medial or the lateral parabrachial nucleus remain unsettled.The relation between the parabrachial nucleus and the K(?)lliker-Fuse nucleuswas discussed.

ObjectiveTo investigate the effects of recombinant human erythropoietin (rhEPO) on the apoptosis of human mesenchymal stem cells induced by H2O2 and related cell signaling pathways.Methods After being cultured in vitro, human MSCs were treated with rhEPO.Phosphorylation of ERK1/2,p38 MAPK and PI3K/Akt was detected by using Western blotting.One h after pretreatment with1U/ml rhEPO,cells were cultured in the presence of1mmol/L H2O2 for1h.Cell morphology was observed under the inverted microscopy.Cell apoptosis was determined by using flow cytometry,migration assay was performed in Transwell chambers,and adhesion assay was performed by plastic dishes.ResultsRhEPO could increase phosphorylation of PI3K/Akt pathway in human MSCs,but reduce phosphorylation of p38MAPK.RhEPO had no obvious effect on ERK1/2 pathway and total proteins of Akt and p38MAPK.RhEPO could decrease apoptosis of human MSCs induced by H2O2 (P＜0.01) and the inhibitory effect was abrogated by Ly294002 but not anisomysin.Conclusion RhEPO could protect MSCs from apoptosis. Activation of PI3K/Akt pathway was involved in the effect of rhEPO on apoptosis.

Previous work showed that there was high ratio of Mycoplasma hyorhinis infection in human gastric carcinoma. P37 protein is a membrane lipoprotein of Mycoplasma hyorhinis. It was reported that P37 inhibited cell adhesion and induced tumor invasiveness. To investigate the function of P37 in cancer development, the p37 gene was subcloned into shuttle vector of pAdTrack-CMV. Linearized pAdTrack-CMV-p37 was co-transformed into BJ5183 cells with adenoviral genomic plasmid pAdEasy-1. The identified recombinant DNA was transfected into 293 cells to package adenovirus. From the supernatant and cell lysis, the presence of recombinant adenovirus P37 was proved by PCR. And then BICR cells with this recombinant adenovirus of P37 were successfully infected. RT-PCR and Western blot demonstrated the transcription and expression of P37 in infected BICR cells. And the soluble P37 protein can be secreted into the culture supernatant of infected BICR cells. In the migration assay in vitro, the number of migration BICR cells infected with Ad-p37 was 52.03% more than that of control. The construction of recombinant adenovirus provided a good tool for studying P37 function and its molecular mechanism, which will be further used for in vivo migration and invasion experiments.

OBJECTIVE To investigate the degree of risk of viral prevalence of HBV,HCV and HIV through blood transfusion in Beijing Hospital in China,and to assess the need of a national Haemovigilance System. METHODS Retrospectively,7883 blood bank specimens (collected from 2004 to 2007) were re-examined using 8 indicators (including 5-item Hepatitis B,anti-HCV,anti-HIV and Syphilis) for the prevalence of most common viral infection. RESULTS From the blood bank specimens,the prevalence of HBsAg was 0.88% (69),the anti-HBc positive blood,only the anti-HBc was found in 2.65% of the specimens,while both the anti-HBc and the anti-HBe were found in 2.09% of the specimens. The prevalence of anti-HCV was 0.09% (7). CONCLUSIONS We need to establish the national Haemovigilance System to strengthen the monitoring of the above HbsAg,HBcAb and HCV indicators to prevent the transfusion-transmitted infection. Only in this way can the public confidence in blood safety be improved.
