Objective To screen proteins in pancreas cDNA library interacting with HBsAg protein.Methods After being amplified and identified,the human pancreas cDNA library plasmid was transformed into yeast Y187.Thereafter,the bait plasmid(PGBKT7-HBsAg) was transformed into yeast cells AH109.Then,two different transformed yeast cells were mated.The diploid yeast cells were plated on synthetic dropout nutrient medium(SD/-Trp/-Leu/-His/-Ade) and that medium contained X-?-gal for selection two times.After plasmids of true positive blue colonies were extracted and transformed to E.coli,the results were analyzed by DNA sequencing and blast searching in GenBank database.Results Six proteins binding to HBsAg were screened,including aconitase(ACO1),CDK5RAP3,carboxypeptidase,etc.Conclusion Most of these proteins play significant roles in the evolution of 2 type diabetes mellitus,which may supply some new clues for exploring the pathogenesis of abnormality of lipid metabolism and tglycometabolism in the patients with chronic hepatitis virus infection.

Background and purpose:The impact of the two factors of von Willnbrang factor(vWF) and integrin?3 on tumor metastasis has not been recognized. This study was done to investigate the expression of vWF and integrin?3 in human lung cancer cell line H460,the association between the two factors and tumor metastasis effect of vWF and integrin?3 on adhesion of human lung cancer cell line H460. Methods:The expression of vWF and integrin ?3 protein was examined by immunohistochemical staining. The impact of vWF and integrin?3 on adherent effect of tumor cells was evaluated by adhesion experiment, antibody inhibiting experiment and MTT.Results:Positive expression of vWF and integrin?3 was detected in H460 human lung cancer cells. H460 human lung cancer cells were able to adhere to vWF. Using anti-integrin?3, we observed that the ability of cell adhesion to vWF was inhibited,and A Value decreased from 1.59?0.06 to 0.55?0.03(P=0.01619). Using anti-vWF, we observed cell adhesion to vWF was inhibited too and A Value decreased from 1.60?0.06 to 0.54?0.03(P=0.01598),which had the same effect when using anti-integrin?3.Conclusions:H460 human lung cancer cells are capable of producing vWF, and vWF expression contributes to metastasis by adhering to cancer cells, integrin?3 is the vWF receptor on H460 human lung cancer cells.

Objective To study the value of MP-DNA in the early diagnosis of pneumonia by analyzing the result of MP-DNA in bronchoalveolar lavage fluid(BALF) and MP-IgM antibodies in serum.Methods 103 hospitalized children were detected for MP-DNA in BALF(positive:DNA copies ＞ 102/ml) and MP-IgM antibodies in serum.Results The MP-DNA positive in BALF and the MP-IgM positive in serum in children with pneumoina were significantly higher than those in children with foreign body in bronchus (x2 =13.00,4.11,all P ＜ 0.05).33.01％ of 103 children was MP-DNA positive,19.43％ of 103 children was MP-IgM positive.The MP-DNA positive in BALF was significantly higher than the MP-IgM positive in serum(x2 =4.92,P ＜0.05).Conclusion The samples of MP-DNA in BALF were collected more difficulty than the samples of MP-IgM in serum,but the detection of MP-DNA can avoid the false negative,which may be of value in the diagnosis and therapy of MPP.
